(this is one of Puppy's stories)
This story begins when I was an innocent young man, 15 years old. We lived in rural Utah, and I was a pretty straight kid. I took the bus to my high school, and while I was aware there were "bad" boys into loud rock music and drinking, that was something I avoided. I had my own innocent hobbies, I was close with my family, my father who worked at a nearby ranch, and my sister Isabel who was a year older than me. My mom was a full-time housewife. I was just beginning to become aware of the opposite sex, with some crushes on girls at my school, but not even as far as holding hands.
It all began one afternoon after school, when my sister came into my room. I braced myself for usual, Isabel complaining about something I had done, or some chore I had forgotten that she had to do. Instead, she surprised me by coming right in and sitting on my bed.
"Mike, what do you know about sex?"
I just stared at her in surprise. "I know it's something you're not supposed to know about, until you're older and get married."
She smiled. "You don't know anything? Don't you talk about it with your friends?"
I had heard only rumors, myths, and exaggerated stories of sexual exploits, none of which I would be comfortable telling my sister about.
"Not really."
"Have you even kissed a girl?"
"No."
"Not even what's-her-name, Suzy, last year she said she was your girlfriend."
"No. She dumped me before we even got that far."
Isabel smiled, with that smug look like she knew an awful lot more than me, which was often the case. I didn't doubt it.
"I've got a secret, and I'm supposed to share it with you." Her smile shifted a little into a look of uncertainty.
"OK?"
"Dad taught me all about it. And now I'm supposed to teach you too."
I just stared, dumbfounded. "Dad taught you?"
"Yeah. Well, not everything. I've still got my virginity. But do you want to learn?" She still looked unsure of herself. "We could start with first base."
It took me a long time to get my head together to respond.
"I'm not supposed to learn that kind of stuff from my sister, am I?"
She shrugged. "Yeah, but who cares? It's not like I'm going to be your girlfriend. It's just physical stuff, you know? So that when you get a girlfriend, you'll know what to do. You think I'm pretty, don't you?"
I stared at her. Of course. Pretty face, long dark hair, curves developing in her shirt and jeans, but I never thought of her that way before.
"Sure. You're beautiful."
Her smile came back. "Thanks!" She came closer and took her hands in mine. They felt so soft. "Let's start with kissing."
That's how it began. That first day, we kissed really gently, then more confident with our tongues. She put her arms around me, and I cautiously put mine around her. We rolled around in my bed, fully clothed, my erection straining inside my pants. I learned the feeling of her body as it pressed against mine, the taste of her lips, the scent of her hair.
The second day, she came into my room and closed the door behind her. We kissed for a while, then she asked me about masturbation and got me to admit I did it. She opened my pants and exposed my young cock, taking it in her hand, remarking that it was smaller than Dad's. I nearly lost it just from her holding me, and when she pulled off her shirt to let me touch her breasts, I did lose it, big time. She laughed gently and helped me clean up the mess, then we went back to kissing. She let me kiss and suck on her nipples, while she stroked me to my second orgasm.
On the third lesson, we both got totally naked and she took me on a tour of her erogenous zones, with a full explanation of her pussy and clit. I was captivated, totally lost in amazement, as my fingers explored her soft intimate folds. She showed me how she masturbated, then let me try it as well. I didn't get her off with my fingers that first time, but she got herself off, so for the very first time, I got to see her come.
On the forth lesson, it was oral sex. After a lot of foreplay and kissing, she smiled and took me into her mouth. I didn't last long, and she simply swallowed. Then she put me to work, learning how to make her pussy and clit happy with my mouth. I learned slow and steady, but she didn't seem to be in any hurry. It seemed to take an hour before she came that first time, but pretty soon it was down to a few minutes.
That's as far as the lessons went, for the first few months. My dad, who was supposedly aware of the whole thing, never said a word about it to me. We continued our life as a regular family, except that my sister and I were always sneaking away to fool around in private. Still virgins, we figured out how to 69. One time when we were alone in the house, we took a shower together, giggling with soapy hands on each other. My parents gave no indication that they were aware of what was going on, although I assumed that father knew, since Isabel told me it was his idea, and that she fooled around with him too.
One day, my father broke the silence, finding me alone, in the living room.
"Mike. There's something we've got to talk about."
I looked at him cautiously. "Yeah, Dad?"
"I know you've been fooling around with your sister for a while now." That was the same phrase Isabel and I used - fooling around. I stared at him. He didn't look upset at all, perhaps just a little awkward at raising a subject he wasn't sure how to discuss.
"Uh-huh." I acknowledged carefully.
"She's a very beautiful girl."
"Uh-huh."
"Have you thought about going all the way with her?"
I stared at him. Of course I had though about it a lot, and Isabel and I had talked about it plenty. I had no idea how to respond.
"Don't worry, Mike." he said calmly. "I think it's totally great that you two are into each other. It was my idea that she practice with you, she told you that, right? Your sister's growing up, she's ready to lose her virginity, but I don't think I should be the one to do it. For one thing, it should be with someone her own age. And since you're younger, you're probably a bit smaller down there, so her first time will be more comfortable. You know I care about both of you, so I want it to be good for you. You want to do it with her, don't you?"
I nodded, barely able to make sense of it, this whole new side to my father I had never known.
"But, um," I fumbled, "I'm not supposed to be doing this, right? I mean, with my sister."
He smiled. "Well, sure, there's some taboo against it. Most folks wouldn't understand, you know that, that's why we keep it secret. But your sister doesn't seem to mind, does she?"
"No... I guess not."
"So let me be honest with you, son. One of us has got to fuck her soon, and I'd rather it was you. And for God's sake, use a condom."
That night, I snuck into Isabel's room after everyone went to sleep. I told her exactly what Dad said. She was excited, kissing me passionately, pushing off my pajamas, pulling me into her bed against her warm naked body. She reached by her bedside to show me a box of condoms, explaining that Dad had gotten them for her. After some minutes of touching and fumbling, I was hard as a rock, we got the condom on together, and then I was inside her. It felt totally, completely right. All those worrying thoughts about what was right and wrong left my mind, as our bodies moved together.
I came quickly that first time, but she assured me it didn't matter. We spent an hour cuddling together afterwards, just touching and talking.
After the first time, it was like the flood gates had opened. We wanted each other all the time. The only constraint was regular life - school, meals, homework. Sometimes we were daring, meeting in my room after school with the parents downstairs, trying to be quiet, my sister muffling her sounds as I rocked into her pussy. Other times we waited for night, the cover of darkness, when we assumed the parents were asleep.
One time we ran out of condoms, and had to wait a week until Dad bought some more to give to Isabel. That week, I continued to eat her pussy frequently, and she took care of me with her mouth. A few times we dared to start fucking, being careful to pull out before I came, letting Isabel use her mouth to finish me.
One Saturday morning, my mom was out shopping, and Dad was downstairs washing the car. It was a hot day. Isabel and I ran into each other in the living room. She came up behind me and put her arms around me, her tits pressing against my back, her breath hot on my ear. I knew what she wanted, and I wanted it too. We made our way upstairs and fell into my bed, forgetting the open door. We were soon quite naked, kissing and fondling, my body between her legs, already with a condom on my cock, ready to penetrate her, when I realized we weren't alone.
"Go ahead, don't mind me." said my Dad, watching from the doorway.
I looked down at Isabel, and she was smiling, clearly unconcerned at having an audience. I decided I didn't care either - if Dad knew we were doing it, why couldn't he watch? I pressed into my sister's hot pussy and we began to fuck. I was mostly paying attention to her, but saw that at some point Dad had moved closer to us, sitting in a chair watching his children fuck. He had his cock out and was stroking it slowly. Isabel was really responsive, moaning and rocking her body to meet my thrusts, her modest-sized perfect tits bouncing with each thrust. I felt myself coming, our bodies shaking together. For a moment I stayed there, softening inside her, then carefully pulled out holding onto the base of the condom. I sat on the bed looking at my sister's naked body, still flushed with the throes of sex, and my father watching both of us, his hand moving slowly in his lap.
"If you don't mind, it's my turn." he said, standing up and dropping his pants.
I just nodded, dumbly, amazed at his boldness.
"Yes, Daddy." said Isabel, still charged up with no release.
I sat back and watched as she took his cock in her hand, fumbling by the bedside for another condom, helping him put it on. I noticed that his cock was indeed a bit bigger than mine. Then he was between her legs, taking my place, fucking her. It seemed very clear it was not their first time. They went for several minutes, in a classic missionary-position fuck, my father's large body rising and falling on hers. She moaned as happily as she did for me, and soon his body made the telltale signs of coming.
He pulled out, and sat on the other side of the bed from me. The three of us looked at each other, a lot of unspoken communication.
"How long do we have before Mom gets home?" asked Isabel, breaking the silence.
"At least a couple of hours." said Dad.
"So we can do it again?" she said seductively, reaching for my cock.
I suppressed a chuckle, then Dad laughed, then Isabel and I joined in, the tension broken.
In the next hour, Dad watched as I lay back and Isabel sucked my cock to hardness, she put a condom on me and rode me, taking Dad's cock in her mouth at the same time. I was close to coming when she rolled away from us and insisted I eat her pussy, which I did happily did to her orgasm, while Dad kept her mouth full of cock. Dad pulled to her hands and knees and fucked her that way, a position we had only done a few times. I played with her swinging tits as Dad gave it to her hard and fast until he came for the second time. He pulled out and I took his place, fucking my sister doggy-style until I also came a second time.
From that day onward, fooling around with Isabel was a bit easier. I knew we didn't have to hide it from Dad, only from Mom. He only walked in on us a few times, joining in. More often it was me and Isabel by ourselves, or the two of them when I wasn't around.
We might have kept going along like that, but the following summer, Isabel and I had an accident with a condom that broke, and she missed a period. She was pretty freaked out, but when we told Dad, he was surprisingly calm about it. Apparently, he had already thought about it for some time.
"You know, abortion is legal now." He looked at Isabel. "Do you want to keep it?"
"Well I can't have my brother's baby!" She looked distraught. "It might have two heads or something."
"It might, but it probably won't. I've read a bit about it. There's a one-in-four chance that your baby will have some major problem, and probably won't make it. Whatever you decide, I'll support you."
"What about me?" I asked. "I don't want to be a father."
"Nobody has to know it's yours." he said. "She can say she got pregnant by some boyfriend nobody knows. A minor scandal at most."
"And who will take care of it?" asked Isabel. "I'm still in school!"
"Your mother and I are well off. We can support another child, so that's not the issue. The issue is, do you want to have it? To be pregnant, to bring this child into the world? To be a mother?"
Isabel asked for time to think about it, which she did largely by herself, quiet in her own thoughts for a week. Neither of us initiated sex with sex with her that week, giving her space. In the end, she found Dad and I alone in the house one day, and told us she had decided to keep it.
"Wow." I said, taking her in my arms and kissing her. She smiled.
"If it works out, I'm going to be a grandfather." said Dad, kissing her as well. "You're pregnant, do you know what this means?"
"It means I'm going to have a baby?"
"Yes, and it means no more condoms."
"Oh. Right." She smiled, reaching for the bulge in his pants, her body expressing her approval. We all went off to a bedroom, where Dad and I took turns fucking her, condom-less. The naked wetness of her pussy around my cock felt wonderful.
Later, when the secret of the pregnancy came out in the family, Mom was pretty freaked out. Isabel made up a story about having slept with some guy she didn't know, apologized for being so promiscuous, and Mom eventually forgave her. But Mom was totally worried about the scandal of a teenage pregnancy in our neighborhood, in Isabel's school. After a whole lot of discussion, they decided to send her away to a boarding school that fall, far away, in Maine. It didn't make much sense to me - sooner or later she'd be home from school with a baby, and everyone would find out eventually. Even in a rural area like ours, people know each other, rumors would spread. But Mom insisted, and Isabel gave in.
We spent the last month of summer fucking up a storm, then tearfully said goodbye when she left in the fall. At school that year, I was introverted, lost in my thoughts, trying to pay attention to my schoolwork, ignoring the social scene. I was a bit of a nerd. I looked forward to when Isabel would be home for two weeks, for Christmas.
When Dad drove her home from the airport, there was snow on the ground, it was bitterly cold, and Isabel was all bundled up. Even with the clothes, I was still shocked to see how big her belly was. We had a small, private Christmas that year, no neighbors invited over, trying to keep the secret. Isabel and I spent long hours together, being careful not to let Mom notice. Pretty soon Isabel and I were in her room, getting naked. I touched her bulging belly and kissed her all over. She was eager, barely sucking my cock for minute before insisting on having it inside her. Fucking my pregnant sister's bulging body was a strange sensation at first. It limited our positions a little, and we had to move sometimes to keep her comfortable, but it was also strangely thrilling, something perverted about it, about spilling all that sperm inside her, when she was already pregnant. Even more perverted than incest, it seemed to me, as I had already become so used to that.
I know that Dad got together with her a few times as well that Christmas, dipping his cock into his pregnant daughter, although Dad and I never shared her openly.
Isabel went back to school, and had the baby during the school year. It caused a minor scandal at her school, some violation of their rules, which required some long-distance phone calls with my father to convince them to let her stay to the end of the school year and finish her finals.
Isabel came home with a baby boy, naming him Joseph, although he never went by that - even as a child, he was always Joe. No extra limbs, no deformities, no fatal defects.
Isabel loved being a mother. Back at home, Mom was always there to help with the baby. Slowly, Isabel resumed our sex life together, back to condoms. A week later, when she came to my room at night, she had a serious look on her face.
"Mike, I want to ask you something."
"Anything." I began to undress her.
"I want another baby."
I stared at her. "You mean, you and me...?"
"Actually, Dad wants to do it with me."
I stared at her, stunned.
"Uh, when we got you pregnant, it was an accident. You mean, do it on purpose? With Dad?"
"Yeah. I realize now that I love children, I want to have a few of them. I'm 18 now, I'm an adult and Dad says I can make the decision. But I want you to be OK with it."
I sat at thought for a while. "So... you and me keep using condoms, and with Dad, you don't?"
"Yeah." She looked apologetic.
"Don't you want to go get a real boyfriend? I mean, someone you don't have to risk getting some two-headed baby?"
She sighed. "But you and Dad are my lovers. I don't want anyone else. Can you see me trying to date other boys, without giving up my relationship with you?"
I shook my head. "I guess not."
She pulled off her top, her swollen breasts tumbling out. She brought one nipple to my mouth, and I sucked, tasting my sister's milk. I started to get hard, and pretty soon we were fucking - with condom. She ground her hips against mine, in pleasure.
"God, I love you, Mike. Thank you for letting me have a baby with Dad." Our bodies slapped together gently, her pussy gripping me rhythmically. "If you like, there's something I would do for you."
"What's that?"
"You could fuck me without a condom..." she paused, holding her body against mine. "But not get me pregnant. Have you heard of anal sex?"
I held her, looking into her eyes in surprise. "Sure I've heard of it. But that wouldn't feel good for you, would it?"
"I'd by happy to try it with you." She looked at me with total love and surrender. "Do you think the idea is sexy? Putting it in my butt?"
My cock throbbed, giving me away. "Um, yeah."
She pulled away from me, wrapping her robe around her body, leaving me in my bed. I saw her head off towards Joe's crib, to check on him, then she vanished downstairs. When she came back up, she had a pat of butter on a small plate.
"Dad told me all about how to do it." she said. "But I'd never let him do it with me, he's too big. You're smaller, it might work."
We spent the next half hour exploring. I licked her pussy while probing her ass gently with a slippery finger, then two fingers. She came once from my tongue on her clit, and her back door relaxed a bit more. Finally she seemed to be taking my two fingers in and out quite smoothly. She told me it was time, so I put the head of my naked cock up against her sphincter. Very, very slowly it went in, inch by inch. She told me several times to stop, trying to relax, then start again.
That first time was a real struggle for her, but I was wildly excited by having my cock buried in my sister's ass, and fortunately came in a few seconds of actual thrusting. The next times got a lot easier.
Over the next month, although I didn't witness it, I knew she was having unprotected sex with Dad. I was happily enjoying Isabel's mouth, sometimes her pussy with protection, and many times her tight ass, bareback. The baby was always needing attention, so I often had the strange experience of Isabel leaving me in the middle of sex, to go nurse or comfort the baby back to sleep, then coming back to me and resuming sex as if nothing had happened.
One hot day that summer, we left the baby at home with Mom, and took a hike together out into the hills at the back of our ranch. We trekked out to a small pool along a stream there, and had a picnic lunch. We got naked and waded into the pool, only as deep our knees but very cold, splashing each other, the cool water feeling great on our hot bodies. On the blanket by the picnic basket, one thing led to another. I felt her pussy, already wet and ready. Being daring, I scrambled on top of her and sank into her pussy.
"Oooh." she moaned. "That feels good, but don't come in me yet." She looked into my eyes. "I think I'm pregnant, my period's late. But let's be safe, OK?"
"OK." The firm ground under my knees made it a bit uncomfortable, but sucking her milky tits and fucking her wet pussy felt great. When I felt myself getting close, I pulled out, and moved to straddle her chest, pointing my cock at her mouth, stroking it. She opened her mouth with acceptance. Just as I started to come, I put it in her mouth and she made a suction-lock, swallowing rapidly.
After the rush faded, I moved down to eat her pussy properly. She moaned quietly for a few minutes, building in intensity, then her body went rigid as she came hard.
"You want to go again?" she said, coming down, reaching for my cock.
"Yes, but we better be safe!" I reached down and touched her anal pucker with a fingertip.
"Oh, you're right, we better be safe." She smiled, moving onto her hands and knees, reaching back to spread her butt cheeks, in a wanton display of submission. I played with her ass to prepare it, then within a few minutes I was balls-deep. I closed my eyes briefly and thanked God for my modest-sized cock, around five inches and not too thick, which allowed me to give my sister a vigorous, hard, butt-slapping ass-fuck in the great outdoors, draining my balls deep in her rectum.
Later that week, it was for sure - she was pregnant with Dad's baby. We fucked like bunnies for the rest of the summer, then she went off for her senior year at the boarding school again. She was home briefly for Christmas for family bonding - of both the innocent and indecent kinds - then off to school again.
That spring, I really tried to act normal at school, to get a girlfriend. I actually did sorta fall in love, or at least in lust, a couple times, with some girls that showed some interest in me. There was some making out in cars, but I didn't go all the way. Really, I should have known it wouldn't work. I was in love with Isabel, but not ready to admit it to myself.
Isabel gave birth that year to a baby girl, who she named Tessa. The baby seemed fine at first. We didn't figure out about the disabilities under a couple years later, but that's getting ahead of the story.
Isabel graduated and came home for good, with Tessa. Now there were two babies in the house, so even with Mom's help, she had less time for hooking with with Dad and me. Still, we found times to be together. On a few occasions, my Dad and I shared her body, on her hands and knees, with me in her pussy and Dad in her mouth, or the other way.
Pretty soon Isabel let us know that she wanted another baby, and she had decided it would be mine. We made the adjustments, Dad sticking with condoms, and she and I for the first time deliberately trying to get her pregnant.
Before we knew for sure whether Isabel was pregnant, a tragic event rocked all our lives - Mom died in a car accident. The loss hit all of us hard - Dad especially. I never knew how their relationship had been as a marriage - it must have been strange, as Dad was fucking his daughter. Had Mom known, or suspected? Had they still been intimate, or was Mom just going through the motions, "staying together for the kids?" I never learned.
After the funeral, the house felt quiet and gloomy. Dad withdrew into himself. Isabel tried to take on more of the cooking, and I did my best to help out wherever I could. While my friends were out partying or cruising girls, I was home helping to take care of the household and two babies. It felt like my childhood had suddenly ended, even though I still had my senior year ahead of me. In a lot of ways, Isabel and I now felt like husband and wife, with two kids - and a third on the way, as she was now definitely pregnant.
Dad's mood finally started to improve. One night after dinner, we had a fateful conversation. Isabel started it, with a frank admission.
"I wish I could marry Mike."
Dad and I looked at her. For a long minute, we were all lost in thought.
"Well, you could." said Dad. Now we looked at him in surprise. "In fact, that might be a good idea. We could move somewhere else, where nobody knows us, and start over. We just wouldn't tell anyone you're related. One of you would have to change your last name, and no longer be my child, publicly."
"I could do that." said Isabel, with some excitement in her voice. "You'd still be my secret Daddy."
"We'd all have to change our last names." I offered. "To be safe."
"How about Smith?" offered Isabel. "I could be a Jones or something, then marry Mike, and be Mrs. Smith."
"We'd need some fake identification." said Dad. "I have an old friend in Texas that could probably help."
And so it happened that we moved from Utah to Texas. We found Dad's friend, who asked no questions when he forged papers for us. We found a town in Texas, rented a house, found a job for Dad as a mechanic, and started making friends. Pretty soon, we were planning a wedding. Our friends were supportive. To the world, it looked like I was finally marrying my girlfriend after having two children out of wedlock with a third on the way. It looked like I was doing the right and proper thing.
We had a small informal wedding, becoming Mr. and Mrs. Smith. Isabel gave birth to her third child, a girl we named Emily. I took my GED to get out of my last year of high school. Dad lived with us at first, but after I found a job as well, he got his own place.
To the outside world, for the next several years, we looked like a totally ordinary family. Isabel went on the pill so we could make love as husband and wife. She was a traditional homemaker and I had a steady job, we raised our three kids in a nice small-town community in northern Texas.
Dad came by almost every week, usually to help babysit. Sometimes, he would stay over, and Isabel would help him with his sexual frustration by sleeping with him, although she always referred to that as sex, instead of making love as she did with me.
In time, Dad found another woman, a nice lady his age named Evelyn, and eventually married her. We were often all together on holidays, the seven of us, as a family. As far as I know, Evelyn never learned anything of the family secret. I knew Dad was happy with her, and he came to secretly partake of his daughter's body much less often, sometimes just on his birthday.
Thirteen years went by. With three kids, we were busy parents, always moving from one drama to the next. The three of them developed into very different young people.
Joe, the oldest at 15, was completely normal. He liked baseball, was popular, although he never had a girlfriend. He bonded with my Dad, his grandfather, doing manly stuff like watching sports or NASCAR.
Tessa, the middle child at 14, was different. We never used the terms "learning disabled" or "developmentally challenged", but it was obvious. Tessa was a sweet girl, very simple, and two years behind in school. Something had clearly gone awry genetically with Isabel having a child by her father, but we loved Tessa no differently. Her good-natured personality was often the glue that kept the household working smoothly. Joe was intensely protective of her. On one occasion Joe heard some boys his age calling his sister a "retard", and he beat them up so bad they never said it again. There was some tension because Tessa's body had blossomed into quite a stunning figure, a pretty face and a curvaceous body, but she was still in a 7th-grade class with a bunch of younger kids. There was a lot of teasing.
Emily, the youngest at 13, was a real handful. Intensely intelligent, even intellectual beyond her years, and a year ahead in school. To the outside world, she was introverted, preferring the company of books, which she devoured in quantity, no mean feat in a small town in Texas. At home, she was talkative, often going on and on about some subject she had just read about - philosophy, or history, or things like that. At 12, she taught herself French from books and cassette tapes. She had the only computer in the house, and was the only person that knew how to use it. She had bonded with me, perhaps because I was the only one who would engage with her intellectually, so she was a "Daddy's girl."
My relationship with Isabel had changed over the years. There was still some passion, but much less often. Sex was down to once or twice a month, with so many other distractions in our lives and the demands of parenting. At 32 and 33 years old, we were still young and fit, but I admit that my eyes wandered to other, younger women. I knew I would never cheat on Isabel, but figured there was no harm in looking and fantasizing. Some of my children's older teenage friends were starting to look pretty hot - around the age that Isabel and I had been when we first became sexually active.
One Christmas, we found ourselves sitting around the dining table with Dad. It was getting late, the kids were already in bed, and Evelyn had already gone home. Just the three of us, and a bottle of whiskey. Isabel, who usually never touched the stuff, had a glass with us.
"Have you talked with your kids about sex yet?" asked Dad. "They're getting to be the age where they'll be curious."
"They get that in school nowadays." said Isabel laughing.
"Joe and Emily are too shy." I said. "And Tessa, well ... her body's ready, but she's not ready to have a boyfriend."
"That might be dangerous." said Dad. "She could end up in a sexual situation, and not know how to respond. Now..." he paused, "I took care of that with my own family. I taught you... well, I taught you, Isabel, and you taught Mike. That turned out pretty well."
We laughed, but I realized he wasn't quite joking. "You're serious, Dad? You think we should teach the girls about sex?"
"The way you taught me?" said Isabel, her laugh changing to a surprised look.
"Sure. That way, they'd be well prepared for when they hook up with a boyfriend or girlfriend. They'll know what to do."
"That's what you said about me." said Isabel. "You said I'd be educated. But I bet you just wanted to get your dick in my mouth or my sweet little teenage pussy."
"Well, that's a side benefit." Dad laughed. "Now Mike here, he could teach the girls in secret, never telling you about it, like I did with your mother. But that'd be a shame. You too are close enough and you have the history together, Isabel, you could teach them too."
"Dad, you're crazy." said Isabel, but I could tell, in the way she said it, she didn't think it was that crazy.
She changed the subject, and that's all we said about sex that night.
It was a cold Saturday night in January. Joe was staying over at a friend's house, Tessa was downstairs watching TV, and Emily was as usual reading quietly in her room. I showered and brushed my teeth to get ready for bed, finding my sister-wife in bed already. She was smiling, rolling over to the edge of the bed and touching my cock.
"Is that for me?" she asked, as it started to grow in her warm hand.
"You are in a good mood tonight, aren't you?'
"Um-hmm." She sat up, taking a hold of my hips. As I stood next to the bed, she pulled my soft cock into her warm, wet mouth. One thing led to another, and soon we were under the covers together, kissing, my half-hard cock in her pussy.
"How would we teach them?" Isabel said suddenly, catching me surprise.
I stopped and held myself inside her. I knew exactly what she was talking about. "How did Dad teach you?"
"Just like I taught you. Starting with kissing, first base. Can you imagine going to first base with Tessa? Or second base."
I imagined it. Kissing my 14-year-old curvaceous daughter like a lover. Not actually my daughter, I reminded myself. What was she? My father's daughter, so that made Tessa my half-sister. And my sister's daughter, so that made her also my niece. Kissing my half-sister-niece. Exploring her erogenous zones. Sucking on her nipples, touching her young pussy...
"Oh, I felt that!" said Isabel as my cock gave a lurch, suddenly much harder inside her. "You do like thinking about it."
"I guess so." I admitted.
"I like thinking about it too." Her voice dropped to a conspiratorial whisper. "I've been thinking about it a lot recently. And when I do, I have to use my fingers or my vibrator." For a minute I thrust into Isabel, both of us with indecent thoughts in our heads, my cock so hard inside her. "Do you want to do go start her education now?"
"Yes." I gasped.
"Then come inside me now. We can't have you all fired up when we introduce her gently."
I let myself come inside my sister-wife, then we dressed and went downstairs, finding Tessa in front of the TV. She wore a warm robe, settled into the cozy sofa. She looked half-asleep, not really watching the show. Isabel and I sat down on either side of her, looking at each other with nervous excitement. We both wanted this.
"Tessa sweetheart." began Isabel. "Your father and I want to tell you something."
Tessa was full awake and looked between us, with that beautiful, innocent smile of hers. "Yeah?"
"You've never kissed a boy, have you?" I asked.
"No. They tease me too much." Tessa still smiled. She didn't let the world get her down.
"Your father and I would like to teach you about kissing, and some other things that feel nice." said Isabel. "Would you like that?"
"Uh, sure." She looked back and forth between us. "I've seen you guys kissing lots of times. It looks like fun."
I was almost trembling, excited but uncertain if what I was doing was really right. I leaned in, put one arm around Tessa, and brought my lips to hers. We kissed. It was gentle, sweet. We kissed again, and again, as she started to get the hang of it.
When my tongue ventured through Tessa's young lips, her tongue came up to meet it, mimicking my actions. Without breaking the kiss, I glanced up at Isabel. She was watching us with fascination, with lust in her eyes. I broke the kiss, sitting back. I took a deep breath, and we all looked at each other.
Tessa turned to Isabel. "Mom, are you going to kiss me too?"
Isabel looked back and forth between us. We hadn't discussed this possibility, and as far as I knew, Isabel had never kissed a woman - not that way. But she surprised me.
"Sure, honey." She bent in and they began kissing.
My cock gave a lurch in my pants, watching mother and daughter, my sister-wife and niece-half-sister, kissing with growing passion.
"Kissing is fun." declared Tessa when they came up for air. "It feels nice." She turned back to me and kissed me again.
"There's some other things we can show you that feel nice." said Isabel. "Would it be OK if you showed us your boobs?"
"Sure." Tessa opened her robe. Under it, she was in bra and panties. At 14, she already needed a bra for support, while I suspect that her younger sister Emily would didn't need one for some years to come. "Boys are always looking at them or saying things about them." Isabel helped unsnap the bra, and Tessa's absolutely beautiful teenage breasts came into view. In the cool air, her nipples visibly hardened.
"This can feel nice." said Isabel, leaning in to kiss, her left hand gently playing with Tessa's nipples. After a minute, Tessa surprised me by actually moaning softly. Isabel moved back and I took my turn, kissing Tessa, my hand roaming over her flawless tits, gently teasing the nipples. I was hard as a rock in my pants. Finally I broke the kiss.
"There's one more thing I'd like to show you tonight. Is it OK if I touch you between your legs?"
"Sure." Tessa spread her legs slightly. She looked at me with excitement and total innocence.
I kissed her and smooth ran my fingers down her belly, dipping them under her panties. My finger ran over her soft downy hair, finding her tender lips, slipping between them, finding some wetness there already. The tip of my finger gently explored all around, pressing ever so slightly inside her, then up to find her clit. To my surprise, it felt quite large and well-developed. My wet fingertip ran around the hood of her clit, and she moaned into my mouth, spreading her legs wider and tilting her hips to give better access.
"Let me try that with you as well." said Isabel. I pulled back and watched as Isabel moved into kiss and run her fingers under her daughter's panties, exploring her daughter's pussy, finding the clit. Soon I could see her fingers moving in patterns, back and forth or in circles. She was carefully testing, paying attention to Tessa's reaction, finding what Tessa liked best. I took the opportunity to suck on Tessa's nipples again, rolling them around my tongue. I put my hand down to join Isabel's for a minute, the two of us stimulating Tessa's pussy together, but it was a bit crowded, so I pulled back. After a few minutes of this treatment, Tessa's small body trembled with the telltale signs of orgasm, coming from the touch of her mother's fingers.
"Wow!" she gasped, kissing both of us again. "That does feel nice!"
"That's enough teaching for tonight." declared Isabel with parental authority in her voice. "It's time you went to sleep, and remember, these lessons are a secret between you, me, and your Daddy."
"OK. Sure!" Tessa grabbed her bra and pulled the robe around her, heading off to her room.
Isabel and I sat together on the sofa, scooting together to kiss. Her hand went down to feel the bulge in my pants.
"I can't believe we just did that." I gasped.
"Are you ready to begin with our other daughter?"
"God. I don't know." I thought about it. "With Tessa, you know what I was thinking? She's got the body of a woman. But the mind of child."
"That's true." acknowledged Isabel. "And Emily, her body's not as developed, but she is 13, and she's got a precocious mind, she might be smarter than both of us put together. So we can ask her, and see what she thinks."
We went and found Emily in her room, reading a book by the light of her bedside lamp.
"Yes, Dad, what is it?" she asked as we knocked and entered.
We sat down on her bed. I paused, unsure of how to approach the subject.
"Your mother and I were wondering if you had some questions about sex?"
Emily smiled, almost laughing, looking at both of us. "Oh, so this is The Talk? The Birds and Bees? Don't worry, Dad. I read all about it, the biology. I know how pregnancy happens. I could even tell you how eagles do it in mid-flight."
I chuckled, and looked from her to Isabel. This was going to be trickier than I thought.
"Book knowledge is one thing. But we were thinking about something else - the real thing. You've never been with a boy, have you?"
"No, Dad. I'm still a virgin, don't worry."
"But you've fooled around with a boy?"
"Oral sex?" interjected Isabel.
"No. But I know what that is." Emily's seemed a little taken aback at her mother's frankness. "They wouldn't tell us in sex ed class. All they talk about is abstinence. But I know how to find a subject like fellatio in a library."
"And do you masturbate?" I asked.
"Do you?" she blurted back, smiling.
I grinned at her cheekiness. "Yes. Your mother and I both masturbate sometime, when we aren't having sex with each other. So do you?"
Emily's voice softened. "Yeah."
"We'd like to teach you some things about how to enjoy yourself." said Isabel gently. "By doing them with you. Would you like that?"
Emily stared at her, shocked.
"Um, you can't do things with me. You're my parents! That would be, um, wrong."
"You're right." I said, carefully. "I've got a different idea. Would you like to watch your mother and I making love? You don't have to do anything you might feel is wrong. But you can see what sex is really like between two people who love each other. You can't get that from a book, or even a movie."
"That would be weird." Emily stared at us, caught off guard. She considered it for a minute. "Weird but ... cool, too. I mean, it's weird that you guys are so open about it."
"You're curious, aren't you?" asked Isabel.
"Yeah." Emily smiled. "That's my weakness, I'm always curious."
We ended up back in the master bedroom. Emily sat in a chair facing the bed. Isabel and I stood facing each other and embraced. We kissed, slowly removing each other's clothes. My cock had been hard since we were with Tessa earlier, and I was eager, but Isabel made me slow down. Slowly we tumbled onto the bed. I kissed my way down her body, from her mouth to her pussy, and she spread her legs to give me better access. I licked her pussy, finding her very hot and aroused. I was a little distracted by our audience, glancing up to see Emily staring at us with astonishment, watching her mother's naked body writhe in pleasure. I was surprised with Isabel barely lasted a minute before having a wet orgasm on my mouth.
I moved up and prepared to enter her, but Isabel wanted to give Emily a full education, pushing me back and sitting up to take my cock in her mouth. Emily stared as her mother gave me an enthusiastic blowjob. I was deliriously excited, worried about coming too soon. Mercifully, Isabel let me go and lay back. I lay down on her gently and began to fuck.
Thrusting my hips and kissing my wife, I paused to glance over. To my surprise, Emily had one hand under her nightgown, moving. She was modest, but there was no question she was touching herself.
It was a good thing I had already come once earlier - it gave me a change to last longer, fucking Isabel for a good ten minutes or so, in missionary. Isabel was very hot, reaching an orgasm of her own in the course of the fuck. I heard some very soft gasps coming from Emily, which might have been her young body coming. That pushed me over the edge.
In the aftermath, I rolled off Isabel and we looked at Emily, smiling.
"Um, thanks." she said sheepishly, pulling her hand quickly from between her legs, and padding off to her own room.
That was how it began.
On times that Isabel and I were alone with Tessa, we gradually went further and further with her. We started with kissing Tessa and masturbating her, but soon we got naked with her too. Isabel showed her how to touch my cock, how to stroke it. Tessa giggled with delight the first time she succeeded in jacking me off to an orgasm, while I was laying next to her and sucking on her tits. She tried touching her mother's pussy as well, and they moved from making out to mutual masturbation.
I was the first one to kiss my way down Tessa's body and replace my fingers on her pussy with my lips and tongue. She loved it right from the start. When I looked up at Isabel, to see if she follow suit, if she would dare go down on her daughter, she looked very tempted, but said "maybe later." Instead, she demonstrated to Tessa how to suck my cock. The first time, I came in Isabel's mouth, but the second time she had me come in her hand, so she could show Tessa what cum looks like, and let her gingerly taste it. The next time, Tessa had no qualms about sucking me to orgasm. I glanced at Isabel as I was coming in her daughter's mouth, and I saw only love and lust in her eyes.
With Emily, we invited her to watch us each time we would have sex, and she never said no. She sat in the chair, watching us on the bed. At first she remained silent, shy, but soon she would ask questions, even in the middle of sex. She watched as Isabel faced her, legs spread, masturbating herself to orgasm. She watched as I jacked myself off, onto her mother's breasts, so she could see the volume and viscosity of the cum. She watched us suck and fuck in many positions, including cowgirl and doggy-style. She often touched herself while watching, but always with her hand demurely under her clothes. Bit by bit, she became very comfortable with our naked bodies, with our sexuality, but still very shy about her own.
She brought home a book on human sexuality, and asked us questions about what she read. She wanted to know how old Isabel was when she first experienced an orgasm, exactly what turned her on, whether she came from oral sex more easily than from fucking. When the subject of anal sex came up, we demonstrated, to Emily's great surprise. She was actually on the edge of her seat, staring in amazement as my cock slowly worked its way up her mother's ass.
One weekend afternoon, Emily cornered me alone, as I was upstairs reading.
"You and Mom are doing stuff with Tessa." she said, a serious look on her face. "Sex stuff."
I nodded. "Yes we are. Very gentle stuff."
"Do you think that's right? She's like a child. Do you understand the concept of meaningful concent?"
I shrugged. "I don't think it's wrong. We went to her, and gave her the same choice we gave you - to learn about sex by trying it with us. Her body is well-developed, and you know it's dangerous. Sooner or later some boy is going to press himself on her, and if she doesn't know what she's doing, she could end up hurt, or pregnant."
"So you're teaching her... for her own good?"
I sighed. "Emily sweetheart. Do you think for a minute your mother and I would do anything we thought would hurt any of you?"
Emily shook her head. "I guess not, but... it's incest."
"Alright. Sit down, it's time you learned some of the family secrets. You're old enough and sophisticated enough that you may understand, and I can sense that with you, it's better to know that to not know."
She sat down, and I spilled the whole tale. How Isabel and I were brother and sister. How my father had introduced Isabel to sex. How Isabel had taught me, how we lost our virginity together, how Joe was conceived by accident, how she and Tessa were conceived on purpose. How Tessa was only her half-sister.
Emily sat still for a while, digesting it all.
"So." She stared at me calmly. "That's why you've never told me anything about Mom's parents." She paused. "Because it's the same people as your parents."
"That's right."
"I'm the child of incest." She said it out loud, as if barely believing it. "I wonder why we aren't all deformed."
"I bet you've studied it, in those books on biology and reproduction." I said. "What are the odds?"
"25% chance of a regular offspring." she said, as if reciting from a photographic memory. "50% chance of some unusual genetic combination that can cause problems. 25% chance of a serious, debilitating or fatal defect." She smiled, grimly. "So I guess Joe is the 25% normal. And Tessa is probably in the 50% problem category."
"And what about you?" I asked gently. "Unusual genes aren't necessarily bad genes."
She thought. "You mean ... me being 'gifted'?" She paused. "You're right. It could be that. I read a book on anthropology about the Polynesians once. In the traditional culture of some islands, brother-sister marriages were seen as powerful, among the ruling class. Sometimes the offspring were deformed, and killed. But other times, they were exceptionally strong or skilled. The missionaries did a good job of wiping that out quickly...." She paused. "So every time I've watched you and Mom together, I was watching incest."
"Yes. I didn't look bad, did it?"
"But everything in the literature on incest says its bad. It's a nearly-universal taboo. It's always referred to as abuse."
"I guess books don't know everything." I smiled.
"When you do stuff with Tessa ... she enjoys it?"
"Tremendously."
"I guess a father-daughter combination isn't always bad then... Mom did it with her father, and that was OK. And besides, I guess Tessa isn't your daughter anyway. Let me think ... she's your half-sister! Oh, that is so weird." She paused and looked at me thoughtfully. "You and Mom have been teaching her....?"
"Yes. To enjoy her body, and to give and receive oral sex."
"And I've only been watching you. So that's a degree of intimacy that she's gotten from you, that I haven't gotten."
"Um... Yes. I guess so." I looked at her in surprise. Our eyes met.
"Would you... would you really want to do stuff with me? I'm not all curvy like Tessa."
"Emily." I sighed. "You are so beautiful to me. I would love to do anything with you."
"Even though I'm your daughter?"
"Even though."
She paused. "You... could kiss me?" The look in her eyes was sensitive, vulnerable - a side I had almost never seen.
I moved to her, and my arms went around her. The hug was innocent, but our kiss was not. It was wet, passionate despite her inexperience.
"Take me to my bed." she gasped, as our kiss broke.
She pulled me through the room, down the hall, and into her bedroom, slamming the door behind us. We tumbled onto her bed, groping and making out like teenagers. My hands, which had touched her so many times, washing her or carrying her as a child, now touched her in a different way, feeling the bumps of her chest through her clothes, now aware of her as a sexual being. She mashed her small mouth against mine with eager inexperience.
"What do you do with Tessa?" she asked, breaking the kiss.
"Well, we started with teaching her to kiss."
"Yes. What else?"
"We showed her how it feels ... to let us touch her sensitive parts."
Emily rolled away from me, off the bed, standing up. In one motion, she pulled her blue cotton dress off her body. She stood there with only white panties, looking at me as my eyes took in the sight of her budding breasts, her small nipples. Then she lay back on the bed next to me. I kissed her, my hands trailing down to caress her breasts, my fingertips teasing her nipples. She giggled with the new sensation, then I moved my fingers down, under her panties, and her giggle changed to a gasp.
"That's my pussy." Her voice trembled.
"Yes. It feels incredible." I gently caressed her lips, with just a hint of hair above. "I can't believe we're doing this."
"Why?" She looked into my eyes. "Because it's incest?"
"Yes - I guess so."
"But you've done it with your sister your whole life, and that's incest too. And Mom did it with her Dad."
"Yes, but..." I pulled my hand away. I couldn't touch her pussy and think at the same time. "You may not be able to understand, it's different when you're a parent. You're my daughter, I love you so much and I've spent my life thinking of how to make you happy, to protect you from any harm."
"Dad, you won't harm me." she said firmly, with the absolute confidence of a teenager. "If you want to make me happy, make me feel good. Show me what you do with Tessa."
I just nodded, reaching down to pull off her panties. I went back to kissing her and sucking on her small nipples while exploring her pussy and stroking her clit. She was already breathing heavy when I moved down and gently started to use my mouth, licking my own daughter's pussy, swirling my tongue around her clit, much smaller than her sister's. I kept at it until I could tell she was coming. I trailed my kisses up her body, holding her in my arms, kissing her lips through her afterglow.
"I love you Dad."
"I love you sweetheart."
"Does Tessa do that for you too? Oral sex?"
"Yes." I admitted. "But you don't have to. For your first time, I'm happy just to pleasure you."
"No way." She stuck out her lip. "There is no way I am going to let my sister try something I don't get to try. I've seen Mom do it to you lots of time. Let me?"
I sighed. "OK. You can experiment."
Emily ran her hands down my chest. I helped her pull off my pants, and my briefs, letting my painfully hard cock escape. She kissed me and I felt her small soft hand grip my shaft. Then she moved down, and I felt her mouth. With no experience, I though there was no chance I would come. But she must have learned something by just watching - or perhaps I was just incredibly turned on at having my cock in my daughter's mouth - because in three minutes in sucking and rhythmic bobbing, I was going crazy.
"Emily." I managed to gasp. "If you don't want me to come in your mouth, stop now!"
"Mmm-hmmm." she moaned, without pulling away. It was too much. I came hard, with my daughter swallowing, for the first time.
That night in bed, I told Isabel about the whole thing, every detail. She got so turned on from listening to the story that I had to fuck her to orgasm before she would let me go to sleep. We hadn't had so much sex with each other in years. It seemed involving the girls had woken up something deep and sexual in her.
Emily and I got together a few more times, always the two of us alone together, in her room. We moved more slowly than the first time, carefully exploring each other's bodies. We lay together naked, touching all over, my hands cupping her precious young butt. The sex was the same: I ate her to orgasm, then she returned the favor.
Isabel and I got together with Tessa again, letting her join us in our bedroom. We explained that I was now teaching Emily as well, and that we had been letting Emily watch us fuck.
"I want to see that too!" said Tessa.
"Let's just fool around together, and maybe we'll do it for you to watch." I suggested.
"Okay." Tessa started to tug at Isabel's clothes. They undressed each other, and were soon laying naked on the bed, breast to breast, kissing, Tessa's hands between her mother's legs. I pulled off my own clothes, delighting in the erotic sight of them together. I knelt next to them, taking a turn to kiss Tessa, then suck her tits, then trailed my lips down her body, going down on her young pussy, sucking her large clit. I was really getting into it, when I noticed that Isabel had moved in close, watching me. I raised my mouth.
"Do you want to try?" I looked into Isabel's eyes. So far, she had been comfortable with kissing her daughter, and mutual masturbation. But not using her mouth. Perhaps that seemed too lesbian, too far out of her comfort zone. She smiled, and shook her head.
"Maybe later."
I raised up to press my mouth against Isabel's. Her eyes widened in surprise, as my lips met hers, realizing I was daring her, pushing her boundaries, my lips dripping wet with the arousal from Tessa's pussy. Isabel froze for a second, then melted, French-kissing me wetly. We swirled the taste of her daughter between our tongues.
"Are you sure?" I asked, breaking the kiss.
Isabel stared at me for a long moment, then she moved down, taking my place. She licked gingerly at Tessa's clit a couple times, making her moan. Then she settled in for good.
"That is so beautiful." I said to her softly, caressing her long dark hair as she ate her daughter's pussy for the first time. My cock was painfully hard, watching her. I sat up on the bed next to them for a minute, and Tessa's hand reached out to stroke me idly as her attention was consumed by her mother's mouth between her legs. Wanting more, I moved up and dangled my cock into Tessa's mouth. She latched on and sucked happily for several minutes, until an orgasm suddenly overtook her.
There was a lot of kissing between all three of us in Tessa's afterglow.
"You said you would show me what fucking looks like?" she reminded.
I nodded. Isabel lay back to spread her legs. I entered my wife, with Tessa right next to us watching every move. Both of us were on edge, so turned on from what we had just experienced, that the fuck was quite short, barely a couple minutes before I came inside her.
"Damn it." gasped Isabel as I pulled out. "I was so close!" She reached down to stroke her clit, staring me. "Finish me with your mouth."
I started to move down, then got a better idea, looking at Tessa. "Would you like to try it instead of me?"
"Sure!" said Tessa happily, so innocent and free. She moved over and took my place.
It didn't bother Tessa that she was performing sex on a woman. It didn't bother her that it was her own mother. It didn't bother her that Isabel's pussy was dripping wet with arousal. It didn't bother her that my white cum was trickling out of Isabel's pussy. She dove in enthusiastically, mimicking what she had seen me do, slurping, sucking her mother's clit. I lay back and watched in amazement, until Isabel cried out and came hard, her body tensing, her toes curling.
"I did it!" giggled Tessa cheerful, lifting her wet face.
We both kissed her and cuddled for a while, then sent her off to her own room.
A few days later, I came home from work. Isabel was in the kitchen, the kids were upstairs. She came out to the living room, a smile on her face, hugging me, welcoming me home. We embraced and kissed.
"You won't believe what Emily did today." she said in a hushed, conspiratorial voice.
"What?"
"She confronted me about what we've been doing with Tessa. Not upset with me, but she wanted to know everything. Everything we've done with her."
"She is very curious." I smiled. "It's her weakness."
"Yes, well, she is curious and she is jealous, too. She wanted to make sure that she's getting the full education, everything her sister is getting."
"Mm-hmm. And you told her about the last time, about you and Tessa?"
"I did." Emily grinned. "I know better than to lie to her. She's my daughter, but in some ways she's smarter than me. So I told her everything. And then she stuck her lip out and insisted that she get it, too."
"You mean...?" I held Isabel's body to mine. My cock was hardening.
"Yes!" She was almost whispering. "I tried to protest, to tell her I didn't have to do it with her. That nobody should do anything sexually if they don't want to. And she looked at me with puppy-dog eyes and asked if I really didn't want to. What a guilt trip! But it worked. I gave in."
"You really did it?"
"I did. I took her upstairs and we undressed each other and we made out, then I went down on her little pussy. God, she's so cute. And she tasted so sweet."
"And did she...?"
"No. Didn't return the favor. And I didn't ask."
"I better have a word with her."
I went upstairs, finding Emily in her room - sitting in her bed, reading a book, as usual.
"Young lady." I began, in my paternal voice. "What you did today was NOT right."
Emily put down her book and gave me a smile, smug, and sultry. Such sophistication in such a young woman.
"What, Dad? What do you mean?" She batted her eyelashes as me.
"You know exactly that I mean. Manipulating your mother like that."
"But she liked it." Emily stuck her tongue out at me. "And I liked it too. Surprising, really. After all I've read about human sexuality, I didn't know how I would feel about the touch of a female. But it was great!"
"That's not the point." I could feel myself entering an argument I would probably lose.
"Come on, Dad. When Grandfather did stuff with Mom way back, you've gotta admit - he manipulated her. And when she seduced you. And when you and Mom started doing stuff with Tessa, and with me. That was all manipulation too. So don't tell me what I did was wrong. Just relax and accept it. Besides, I bet it turns you on." She smiled. "From what I've read about male sexual fantasies and lesbians, I bet you got turned on when Mom told you what she did with me. Just like when you watch Mom and Tessa together."
I opened my mouth to speak, but she was right. In fact, I was still hard, in my pants.
"How about I make it up to you?" Emily pulled back the covers, revealing her body in just a T-shirt, her naked pussy drawing my eyes. She got out of the bed and came to me, dropping to her knees and putting her hands on my belt. "Can you think of anything I could do?" She batted her eyelashes again.
"Jesus." I gasped, giving up, letting her undo my pants, pulling them down along with my briefs. Half-naked, on her knees, Emily took the head of my hard cock in her small mouth, starting to suck, looking up at me with big eyes, happy in her control over me.
For a minute I was overwhelmed by the sensation, by the situation. Then the small part of me that was still upset with her took control. I ran my fingers through her soft dark hair, holding her small head in my large hands. Gently at first, but then more firmly, I started to pull her head toward me, a bit faster, pushing farther into her mouth. We had never done this. She made some noises of struggle as I came closer to her gag reflex, but I kept going. I was close. Now I had a hold of her head, it was no longer her sucking my cock - it was me, fucking my daughter's mouth, using her, like just another wet hole to dump my cum in. And I did, coming hard, holding her head steady as my knees trembled, filling her mouth with my seed. I heard her swallowing several times.
"That was mean..." she said, when I finally pulled away.
I looked at her with concern, suddenly feeling guilty. Had I hurt her feelings? Had I gone too far?
"But I deserved it." she concluded, and smiled. "God, Dad. I've never seen that side of you."
"You... you..." I sputtered. Outmaneuvered by a 13-year-old girl. "You had better get some clothes on, before your brother or somebody sees you going around half-naked."
"Why?" She stuck her tongue out at me. "Shouldn't I introduce him to the family secret too, like your sister did for you?"
"Emily!" I gave her a firm look, then softened. My mind didn't have time to process it. "Maybe. Someday."
I pulled up my pants and left her in her room, walking away wondering how I could be so helpless with her.
The next time Isabel and I invited Emily to watch us - for her sexual education - she did much more than watch. With newfound self-confidence, she pulled off her clothes and got right in the bed with us, watching up close as Isabel and I gently kissed, moving through touching and foreplay, until I was hard, Isabel was wet, we were ready to fuck.
Emily sat right next to us, cross-legged, wearing only a tight-fitting T-shirt, touching herself as she watched. I slid my hard cock slowly into Isabel, moaning in pleasure. Emily stared at the point where her parent's bodies merged, her fingers on her little virgin pussy. She leaned in, her lips seeking mine. Gently, I kissed Emily as I started to fuck Isabel.
"That must feel so good." said Emily, pulling back to watch. She lowered her voice. "I wish I could do that."
"You're too young." I said. "Your first time should be with a boy your own age."
She nodded in agreement, but I could sense she didn't entirely agree. Her finger moved more quickly on her clit.
"If you ask nicely," I said, "Your mother might help you with that."
Emily looked back and forth between us, figuring out what I meant. Then she nodded and turned to Isabel.
"Mom... would you... um, could you lick me like you did the other day?"
Isabel, highly turned on in mid-fuck, didn't hesitate. "Sure, honey. Come here, sit on my face."
"Oh!" Emily giggled, then she did it - climbing up and squatting over her mother's face, lowering her little pussy to Isabel's mouth.
My cock lurched, growing even harder inside Isabel's pussy, penetrating deeper, as I watched Isabel's tongue come out and slip between her daughter's labia, then Emily was tilting her hips, finding the most pleasurable angle on her mother's mouth. I held onto Isabel, cupping her generous tits and fucking her harder.
To my surprise, we managed to keep going for several delicious minutes. I managed to hold back my orgasm. Emily came first, squealing with surprise then rolling off to one side, panting, regarding with us with lust-glazed eyes.
"Your mother has done that for you twice now." I said, thrusting steadily. "And you haven't returned the favor." I got a wicked idea, pulling out, my cock hanging there in the air, dripping wet. "Would you like to taste her?"
Emily smiled, nodding, leaning forward, taking my wet cock in her mouth. She sucked it clean, the licked each side of it.
"It tastes sexy." She smiled at me.
"Are you ready to try it?" I look from her face down to Isabel's pussy.
Emily looked uncertain.
"Your sister is already quite good at it."
Emily stuck her tongue out me, then smiled. "And you say I'm manipulative? Let me."
I moved aside and watched as Emily took my place between her mother's legs. She cautiously began to lick.
"Put some fingers in me, sweetheart." said Isabel, looking down tenderly. "My pussy feels empty."
Emily put one, then two, then three fingers into her mother's wet pussy. I moved up to dangle my cock in Isabel's mouth, watching as Emily gradually figured out how to pump them in and out, combining a finger-fuck with clit-sucking. She kept it up, growing more confident, for a couple minutes, until Isabel reached a toe-curling orgasm from her youngest daughter.
I still hadn't come. They allowed me to position them how I wanted, with Emily laying down on her back, on top of her mother, both of their legs spread. I got between their legs and slid into Isabel's pussy, laying down on Emily. Her body was sandwiched between us. I kissed Emily. Isabel's hand came around to cup Emily's breasts, pushing them together, almost making cleavage. I sucked on her little pink nipples as they were presented to me. Reaching between us, I found Emily's pussy, and for the first time I slipped one finger carefully into her pussy, through the constriction of her hymen. Still sucking Emily's nipples, I finger-fucked her while hard-fucking Isabel, until I suddenly came.
Spring was approaching. In the flurry of domestic life - homework, cooking, my job, the kid's hobbies, after-school sports - there often wasn't much time for fooling around. The bounds of sexual behavior in the house were set: One daughter or the other would join Isabel and I in bed. Sometimes, it was just Emily and me together. We taught both of them, separately, about how to 69. It was a lot of fun to have one of the girls on top of me, and a delight to watch them 69 with Isabel.
Joe, as far as I knew, had no idea what was going on with his sisters. He continued to be a solid B student, Emily got straight As. Tessa's grades were irregular - not quite so dismal that she would be forced into "Special Ed" classes, but usually not passing either. She was headed for repeating seventh grade, again.
Tessa was fascinated by watching Isabel and I fuck. She sometimes pressed fingers inside herself, while she watched, imagining what it must be like. She told us about boys at her school that she thought were cute, that she got excited thinking about. It worried me, it worried Isabel. We talked at length about what to do, and came to a conclusion.
One day, I worked up the courage to sit down with Joe, alone, and have a man-to-man talk. I approached the subject gently, offering to clear up some family mysteries he had always wondered about - like the identity of his mother's parents. He was pretty freaked out.
"Mom's your sister?!"
I smiled calmly. "You can see why we don't just tell everyone. It's a family secret." I gave him the whole story. I explained about the genetics of incest. I explained about Tessa, how she was actually his half-sister, daughter of his mother and grandfather. Joe's jaw hung open in amazement.
"But... but... this can't be true."
"You can ask your mother. Or Grandfather. Or Emily, she knows the whole story now too. But not Tessa. I don't think she'd understand."
He nodded. "Hell, Dad. I'm not sure I understand either. It's seriously weird."
I sighed. "I'm telling for a reason. I know you might have preferred to go through life not knowing. But just as Grandfather introduced your mother to sex, the girls have been learning from us too."
"You... and my sisters?" He looked really alarmed now.
"Calm down - they're both still virgins. We've only taught them gentle stuff. Just like how your mother learned. She turned out just fine, even with learning sex from her father, and doing it with her brother. But what I'm trying to tell you is, there's a reason you need to know. Tessa has the mind of a child, but the body of a well-developed woman. Sooner or later, she's going to lose her virginity with a boy. Some boy, who might not treat her right, some boy, or man, that would take advantage of her... innocence. She could get hurt - physically, and emotionally. I don't want that to happen."
"Damn right." Joe looked at me seriously. "I'd beat him to a pulp."
"So what I'm trying to say is - Tessa's first time should be with someone she loves. And trusts. Someone her age, someone close to her." I stared at him. "That can only mean you."
Joe stared at me, his jaw dropping again. For a long minute, he didn't say anything.
"Dad - that can't be right. You're asking me to ... have sex ... with my sister?"
"Half-sister." I corrected. "Now, you don't have to jump all over her. Take it really gentle, slow. You're still a virgin, aren't you?"
"Yeah." He seemed to be calming down.
"Tessa would love to show you what she's learned about kissing, and oral sex. You don't need to go all the way until you're both comfortable. But, knowing Tessa, that'll be pretty soon. And you've got to admit, she's a sweet girl, you love her, and she's got a totally hot body. Whatever you do, don't tell her it's not right, or try to explain about incest. It would just confuse and upset her. And one other thing: When you do go all the way, use a condom."
"Jesus, Dad." Joe stared, his mind overloaded.
I told him not to worry, and left him to think about it.
Isabel and I sat down with Tessa and prepared her as well. We told her that it was OK to have sex only with people that she loved and trusted. That it would be OK to try it with Joe. That he would enjoy it. And it had to stay a secret, in our family.
The very next day, Tessa excitedly told us that she and Joe had started to fool around. They had kissed, and he had been so excited to touch her bare tits. They fooled around in private, but we got regular updates from Tessa as the flirtation developed. The first time he put his hand on her pussy. The first time she sucked his cock.
Spring break arrived. The kids were out of school for a week. Joe went off to a camp with a bunch of boys his age. We knew Tessa planned to stay active with a lot of soccer games, and Emily would most likely hole up in her room with books, or down at the library.
That Sunday was my 33rd birthday. I expected that Isabel would bake me a cake, and the girls would probably give me some small gift, like a tie, or something they made in school art class. It turned out rather differently than I could have expected.
The first surprise was waking up to a blowjob - Isabel's mouth around my morning erection as I gradually woke up. She sucked delightfully until she was sure I was totally awake, then moved up to kiss me.
"Happy birthday." She smiled. "I'd finish sucking you off, but you have more surprises in store today." She went to the closet to get dressed. "Go ahead, go downstairs, breakfast is almost ready."
I pulled on some clothes, went to go pee, shaved, then made my way downstairs. A delicious smell came from the kitchen, and the scampering of feet.
"Just sit down Dad." came Emily's voice from the kitchen. There was a clattered of dishes.
Soon, Emily and Tessa came out of the kitchen, with waffles and bacon. I was somewhat surprised that they had made breakfast together - something they had never done before. But I was also surprised that they wore skirts - and were otherwise completely topless, their adolescent tits magnificently perky. They set the food down.
"Happy birthday Dad." Emily leaned toward me, offering her nipples to my mouth. I happily sucked each of them in turn.
"Happy birthday!" said Tessa, leaning in and getting each of her larger nipples sucked.
Isabel came downstairs - also topless - and everyone sat down to eat.
"It's quite a view." I said, looking around the table at three sets of tits, as we all dug into the waffles.
"You like?" Isabel beamed. "I thought you might, since it's just the four of us here this week."
"It's a little distracting." I laughed, and the girls giggled. Somehow, I made it through breakfast, making small talk. When I pushed my plate away, finished, Emily stood up from the table.
"You really like sucking my tits, don't you?" She dipped a finger in the maple syrup, touching it to her nipples.
"I sure do." I admitted, as she moved to my side. I sucked the syrup from her nipples until they were red and puffy, then it was Tessa on my other side, offering her sweetened nipples for me to suck, then Isabel. I was hard as a rock.
"Come take a shower with us, Dad." Tessa tugged at my sleeve.
"With both of us." said Emily, giving me a wicked grin.
"They planned it." said Isabel, looking at me with a smile and a shrug. "It wasn't my idea."
I found myself upstairs, in the larger shower in the house, with two eager teenage girls. They undressed me, pulled off their skirts and panties seductively, got the water hot then pulled me inside. I was sandwiched between Emily's thin, trim body and Tessa's soft curves and plush tits, as we splashed and played and got soapy. They took turns kissing me, as my hands went everywhere, over their bodies and between their legs. Their soapy hands gently squeezed my cock, getting me all clean.
I had one finger gently inside Emily's virgin pussy, as Tessa was stroking me and playing with my balls.
"Dad, put one in my butt." Emily wiggled her hips at me.
"Are you sure?"
"Sure. Mom takes your whole cock in there. I'm sure I can take a finger."
"Me too!" said Tessa.
I complied, and soon had one slippery, soapy finger in Emily's ass, and one in her sister's. It was hopelessly tight, but an incredibly sexy sensation.
"I never thought you would .. be with me together." I said.
"Sure, Dad. There's some things you don't know." Emily gave me a wicked smile, then winked at Tessa. Tessa smiled, and they moved together, in front of me, their soapy tits sliding around me until they were pressed together, then they kissed. A hot, passionate kiss, the sisters going at it with total abandon. My cock, in their squirming hands, gave a lurch and I almost lost it. I wiggled my left and right index fingers, my left in Emily's ass and my right in Tessa's.
"Let's get rinsed and out of here before you come." said Emily prudently.
Once rinsed and toweled dry, the girls led me to the master bed. Isabel was already there, naked, on her hands and knees. They directed me to lay out on the bed, on my back, my legs spread. I lay back happy, ready for anything. Isabel took my cock in her mouth, and with a warm naked girl on either side of me, I though this would be nice - a suck from my wife, with an audience. Then the girls moved in from either side, and I realized what I was in for.... a triple blowjob.
I pulled a pillow to prop up my head, so I had a perfect view as they each took turns, each taking as much of my cock as they could. Isabel licked my shaft while the girls' tongues played with the head, then Isabel was sucking my balls as they girls alternated bobbing their head. They kept me going for a long time, like torture, not letting me come. I was going crazy. I tugged at Emily, and she let me pull her up to me, straddling my face, settling her pussy down for me to suck it while her mother and sister sucked my cock. Then it was Tessa's turn, her softer thighs and bigger clit in my mouth as the other two sucked.
"I can't take it anymore!" I cried. The girls giggled, moving down.
"OK, let's finish him." said Isabel. She sucked my balls into her mouth. Emily took the head of my cock in her mouth, and Tessa used her fingers to stroke the bit of exposed shaft, in effect masturbating me into the suction of her sister's mouth. I reached down and squeezed one of her tits, staring at the obscene sight of their mouths on my cock, and let myself go.
Before passing out, I was dimly aware of Emily kissing her sister, then her mother, sharing my cum between their mouths.
That Sunday was the beginning of a week of sexual freedom, but there were more surprises in store for me before the end of the day. During the day, the girls kept me going with teasing and suggestive body language. I mowed the lawn, and Tessa sunbathed naked in our private back yard, distracting me. I tried to sit in the study going over the bills, but Emily came in to make small talk, pulling up her skirt and casually touching her pussy, pretending nothing was going on. I found Isabel doing some housecleaning wearing only a T-shirt, with a lot of sultry glances and booty-shaking as I attempted to move around the house. I tried reaching for her, but she just smiled and slipped away from my grasp.
That evening for dinner, they were all topless at the dinner table again. I looked around at the girls, exasperated.
"Oh, Mike." said Isabel in a teasing voice. "Did you have a hard day?" The girls both broke out in giggles. I smiled and nodded my head. Tessa's tits, wiggling as she laughed, kept drawing my eyes to her.
After dinner was cleared away, they brought out a small cake with candles, and sang happy birthday for me.
"Did anyone get me a present?" I asked light-heartedly. "I mean, beside the wonderful present this morning."
"Actually, Emily has something for you." said Isabel with a smile, looking at our youngest daughter.
I gave Emily a warm look. She met my eyes, but seemed suddenly shy.
"Dad?" Her voice was soft. "Would you ... would you take my virginity?"
I swallowed. "Um, sweetheart, we've been over that before. You should lose it with some boy your age, don't you think?"
"But I don't like any boys."
"Think about it." said Isabel. "My father didn't want to take my virginity, partly because he's got a big cock. But you're comfortably normal-sized, Mike. And you know Emily has always been a Daddy's Girl."
"And I'm the last virgin left." said Emily, looking over at her sister.
I turned to my right. "Tessa?"
"Yeah!" She beamed. "Me and Joe did it on Friday night, before he left!"
I sat there for a minute, taking it in.
"You... you used a condom with Joe, like I told him to, right?"
"They didn't need one." Isabel was smiling at me from across the table. "I put both girls on birth control pills recently."
I sighed. "Wow. I guess there are some secrets around here, even from me."
"So will you, Dad?" insisted Emily. She looked at me with hope, and vulnerability. "Would you be my first?"
My heart trembled. I couldn't say no to her, not when she asked like that. But there was still some part of my mind, somewhere deep, that insisted that taking my 13-year-old daughter's virginity wasn't right. Slowly, I wrestled with the options. Could I suggest that she do it with Joe first, instead? But she was so much closer emotionally with me. Could I promise to do it later, when she was older? I started to speak, but the words didn't come out as I expected.
"Yes, sweetheart. I'll be your first."
"Cool!" She hopped up from her chair, dashing to my side, throwing her arms around me. I kissed her, and she kissed back passionately. I almost lifted her onto the table to fuck her right there on the spot, then my rational mind regained some control.
"Where would you like to do it?" I asked through the kisses.
"In your bed."
"Do you want to be alone?" asked Isabel, her face full of emotion. She was the type of person to cry at weddings - happy tears, at a rite of passage, and that was certainly the case here.
"No, Mom, Tessa, you guys should be there too."
Emily shrieked with surprise as I picked up her small half-naked body, giggling as I carried her up the stairs. The cake was left on the table, forgotten. The others followed close behind. In the master bedroom, I laid her out on the bed, kissing her. Tessa was by our side, pulling off her sister's skirt and panties. Isabel was right next to me, helping me out of my clothes. Naked, I lay beside Emily and kissed my way down her body, ending up on her small pussy. She made soft noises of appreciation as my tongue snaked around her pussy and swirled over her clit. Glancing up, I watched as Emily was kissed and caressed by her mother and sister.
"Let me." said Isabel after I had licked happily for a couple minutes. I switched places with her, moving up to kiss Emily as her mother went down on her pussy. After a few more minutes, it was Tessa's turn, moving down between her sister's legs. I had never seen the two of them together this way, just a kiss in the soapy shower that morning.
"We've been doing it for a while now." said Emily to me softly, as if answering my unspoken question. "She's so good at it. She can make me come even better than you or Mom."
Sure enough, in barely a minute, Emily's body flexed, her breathe coming in gasps, as she came on her sister's mouth.
"I'm ready, Dad." Emily's eyes met mine with excitement.
"Do you want to be on top?" I asked her. "So you can be in control?"
"No, I want you on top Dad. I want you to do it like you first did with Mom when you were my age."
I got on top of her in missionary, my arms around her small body, her arms around me. We kissed, and I moved my hips so the head of my cock found its way to her velvet slit, pushing gently against the obstruction.
"Are you ready?" I thought to warn her about what she would feel, but then remembered that with all the books she had read on sexuality and anatomy, she probably knew better than I did.
"Yes, Daddy. I love you."
"I love you too, Emily."
I pushed, and that was it. Completely wet and slippery from the oral sex and orgasm, there wasn't much discomfort for her as I pressed my way into her incredibly tight virgin pussy, and gently began to fuck her. Her right hand gripped her mother's. Isabel looked at us beaming with love, a single tear of joy running down her cheek as she watched our daughter deflowered.
As physical sex, it was brief and limited, but emotionally it was tremendous as my thrusts picked up speed. A whole day of teasing, and the precious vulnerability of my daughter, this gift for me, had me on a short fuse. I bottomed out in her pussy once, and came, hard, my arms around her, our lips locked in a kiss, my balls clenching again and again as I flooded her with my sperm.
We all lay in a tangle of bodies afterwards, cuddling.
"Do you want to fuck me too, Dad?" asked Tessa.
"Yes, sweetheart. But not tonight."
Tessa went off to her own bed, but Emily slept with us that night, cuddled up between our bodies.
Monday morning was harsh, the alarm clock, the rush to get ready for work. All I wanted to do was stay in bed with my wife and daughter, but spring break didn't apply to my 9-to-5 job, so off I went. All day long I could hardly focus on work.
Coming home, I was barely through the door when my attention was captured by the delicious smell of dinner cooking, and the sight of Tessa coming in from the backyard, topless, in a short skirt. From the look of it, she had been sunbathing again, although the sun was now low in the sky.
"Come on, Daddy, we have time before dinner!" She giggled as she ran up to me and took my hand.
"Time for what?"
"For sex! You said you would do it with me."
I didn't protest any further as she led me upstairs to her room. I was still in the slacks and polo shirt that I wore for work, but Tessa's hands were all over me, tugging off my pants. I tried to hold her in my arms and slow her down a little. She let me kiss her and suck on her magnificent tits, but she also had her hand on my hard cock, stroking it impatiently. I suddenly knew how I wanted her.
"How did you do it with Joe?" I asked.
"With him on top of me." giggled Tessa.
"Then I'm going to show you another way."
"Cool!"
She let me led her on the bed, onto her hands and knees. I pushed off my pants and briefs, getting on the bed behind her. I lifted her short skirt, and pulled her white panties to the side. Slipping one finger into her pussy, I found her hot, tight, and already surprisingly wet. There was no need for preliminaries. I lined up my cock and worked it in gently. Tessa moaned softly at the new sensation. I held her hips and started to fuck. It was intensely pleasurable immediately, and after a minute, Tessa started to get into it too, gently rocking her hips back to meet my thrusts.
It was different, I thought - the part of my mind that was still in rational control, as my hips thrust deliriously into her 14-year-old pussy. It was different than with Emily. Socially, I was Tessa's father. But biologically, I was not. What was I? Her half-brother. And her uncle. And she was simple, with the mind of a child. But that was a decision already made, when Isabel and I had started teaching her to kiss that night on the sofa. Already made, when I had let her suck my cock and swallow my cum. And her body was so ready - she was really enjoying herself, her body made to love fucking. She might never marry, and she would probably always be like a girl - and most likely, always be available for me to dip my cock into.
I came inside her. She giggled as she felt my cum, then it was time for dinner.
That night, Emily cornered me alone. She wanted to know exactly how Tessa and I had done it. I told her, and she insisted on me doing the same with her. I obliged her - in her room, by the light of her bedside lamp, pulling off her shirt, on her hands and knees on the bed, lifting her skirt and pushing aside her panties, giving her a doggy-style fuck. Her pussy almost painfully tight, I barely lasted three minutes. Differently from Tessa, she really wanted to cuddle afterwards, so we lay together in her bed talking until it was time to go to sleep.
Back in my own bed, Isabel reached for my cock, finding it soft.
"I'm sorry dear. The girls have drained me completely." I explained exactly where my cock had been.
"Oh, that's OK." She cuddled up against me. "I had a lovely orgasm today already."
"How did that happen?"
"Tessa." Isabel grinned. "I found her in the yard, sunbathing naked again, and she was so beautiful I had to kiss her. One thing led to another, and she was so eager to go down on my pussy. Emily's right, Tessa is really good at it. She knows how to use her fingers and tongue together on me, and I had such a wonderful come."
"She does seem quite uninhibited." I agreed.
"Very. I think casual sex comes naturally to her. I guess we'll see as she grows older."
Each night that week, my cock was in demand. When Emily came to me, it usually wasn't for sex - more often she wanted to talk, or tell about something she'd learned in a book, or just cuddle and spend time. But when Tessa came to me, it was predictable - she wanted sex. She barged in on me in the shower one morning, and I could not refuse her - I let her join me in the shower, and fucked her there, standing up, bending her against the wall, the hot water streaming over our bodies as I quickly drained my balls in her, before leaving for work.
When Emily found out about it that evening, of course she wanted the same. So we went into the shower, giggling together, getting clean and touching each other. I had to spread my legs quite wide to get my cock down to the level of her pussy, the hot water splashing everywhere as she bend forward to accept her father's cock in her tight hole.
With all this newfound pussy, I never came in their mouths that week. Giving head was just a warm-up, to get me ready for real fucking.
On Friday night, I got up from watching TV with Isabel, following the sound of giggling up the stairs and into Tessa's room. I found the two sisters naked together, in a 69, with Emily on top. Emily looked up to invite me to join in. I undressed and sat next to them for several minutes, just admiring the beautiful sight of their bodies together, caressing them. Finally I dipped my cock into each of their pussies. With a little practice, we figured out I could fuck Tessa at the same time her sister licked her clit, and for the first time Tessa came with me inside her. Moving around, I carefully fucked Emily doggy-style with her sister still underneath her. I found I could move easily between Emily's pussy and her sister's mouth, but I knew where I wanted to come. Without my even asking, I felt Tessa sucking my balls into her hot mouth as I pressed deep into Emily and filled her with her daddy's cum.
Joe came home from camp the next day, Saturday morning. I worked outside all morning, tending the landscaping around our house. I was hot and sweaty when I came in for a cold drink, sitting with Isabel in the kitchen. Ever so quietly, from upstairs, I heard the sound of heavy breathing, the slap of bodies against each other.
"I guess Joe really missed his sister this week." said Isabel with a chuckle.
I laughed with her. "Do you remember the first time Dad walked in on us?"
"Yes, perfectly." She grinned. "You looked so shocked when you rolled off me, and he rolled on. You probably didn't realize that you would be sharing my body quite so openly."
"I don't think it's going to work in this house, for us to hide sex from each other. The walls are too thin."
"I already told them you know everything, so there's no need to hide from you, or from Emily." She grinned wickedly. "You want to go watch them?"
"You mean the both of us?"
She shook her head. "I'm fine with having sex with the girls, but I don't really want to get involved with Joe. I mean, could you see doing it with Mom? Mother-son doesn't feel right to me."
I nodded. "That's totally up to you. It would probably freak him out anyway."
I went up the stairs, following the sound to Tessa's room. They hadn't even closed the door, no wonder we had heard them! I stood at the door, watching. My son, strong and fit, his naked body on top of his sister, his hips pumping away. It was a delightful sight, pure raw youthful sexuality, forbidden fruit.
"Go ahead, don't mind me." I said.
Joe looked up with a start, glancing up at me with a look of surprise. For a moment, he froze. Seeing the calm look on my face, he soon relaxed as well, and his hips started to move again. I sat down in a chair facing the bed, pulling out my own cock and gently stroking it as I watched. Tessa was so beautiful, her pretty face, her generous tits bouncing with each of Joe's thrusts, her legs wrapped around his, pulling him into her, loving every minute of it. It didn't look like he would last long, and I was right - he came quickly, rolling off of her. I was overcome with a strange sense of deja-vu, a flashback of being in his position many years ago, with my own father.
"If you don't mind, it's my turn." I said, standing up and dropping my pants.
He just nodded, dumbly, amazed at my boldness.
"Yes, Daddy." said Tessa, still charged up with no release.
I climbed on and gave Tessa a royal fucking. There was no more holding back, no more being so careful with her inexperienced pussy. She clearly enjoyed a vigorous fuck, and that's what I gave her. I realized that one thing was different from a generation before - no condoms. Her pussy was still slippery with her brother's sperm. I soon added my own sperm to the depths of her tight pussy, then pulled out and kissed her. I patted Joe on the head affectionately.
"I'll bet she's ready for another round, son."
"Yeah!" agreed Tessa.
"I guess... I guess we'll share her?" managed Joe, still looking a bit disoriented.
"That's what she would like best." I agreed, leaving them together. As I walked away, Joe was climbing on his sister for another go.
The next week, the amount of sex went way down, finding a balance. The sexual tension between my daughters and I simmered down to a more reasonable level. Tessa was well matched with Joe, the two of them sneaking off to fool around almost every day. Although there was no real need to, they tried to be discreet. I spent more quality time with Isabel, less with the girls.
My father was coming to visit the following weekend. I sat alone with Emily in her room one night, and asked her about it.
"Emily, sweetheart. How do you feel about your grandfather?"
"Grandfather? I like him, although he is a proletarian dork. Why?"
I chuckled at the range of her vocabulary. "Because I just know he's going to want to have sex with you and your sister. It was because of him reminding us, that your mother and I started to teach you both about sex."
"Geez. Grandfather and me?" She screwed up her face. "He's a dirty old man. I mean, not literally dirty. I'm sure he cleans up nice. But he's like, how old?"
"He's 54 this year."
"Can he even still get it up?"
I laughed. "He sure can. You know he comes by to fuck your mother a few times a year."
"Oh. Right." Emily considered it. "I'm sure he'd love to do it with me. And I guess I could get into it. I mean, it's really kinky. Letting my grandfather fuck me." She smiled. "We'll see."
"He's actually more than your grandfather. He's both of your grandfathers, by your mother and me. A double-grandfather."
"Oh. Yeah." She looked thoughtful. "And of course he'd want to do it with Tessa. She's his daughter - and his granddaughter! Wow, that's so weird. It would be hard to draw the family tree for us, it'd be all tangled up."
"And Tessa loves sex, and likes her Grandfather too, so of course she'd do anything he asks."
She nodded. "Geez." She patted me between the legs, finding a bulge. "Well, I can see you think the idea is sexy too. Your male physiological response gives you away. Want me to take care of that for you?"
I grinned. "That would be great, sweetheart."
My daughter moved down to fish my cock out of my pants, stroking it, then bending down to take it in her mouth. She sucked for a bit, then raised her head.
"Is Grandfather bigger than you?"
"Yeah. A little. But don't worry, he'll take it slow with you if you tell him to."
"My sister will probably love it." she said with a sigh, then she returned to the task of stroking and sucking to make me come in her mouth, which she did perfectly.
My dad did come over that weekend. He spent the afternoon doing man stuff with Joe - throwing a baseball, talking sports. He joined us for dinner, then afterwards, with the kids gone off to their rooms, he brought out the bottle of whiskey. Isabel and I joined him for a glass.
"So, did you educate your girls?" he asked. "The way we talked about?"
"Oh yes, Daddy." said Isabel. She must have been slightly drunk, as she never called him Daddy openly unless they were having sex. She started the story, and I joined in. Dad took it all in with astonishment and a huge grin on his face.
"Jesus H Christ! You've done better than I could have ever imagined!" He looked at me. "I figured you might get one of the girls to do it with Joe. And I figured if you did that, Mike could dip his cock in a bit as well. But you, Isabel!" He regarded her. "I am so surprised with you. Lesbian sex with your girls! That is so, so fucking sexy."
"I'm glad you think so, Daddy" beamed Isabel.
"And I've already asked them about having sex with you, Dad." I said. "If you ask nicely and go slow, you could probably try it with them."
"Holy Toledo." He looked as me in astonishment. "I never even considered that, with my granddaughters! Well, OK, that's a lie. I considered it, but I didn't think it was a real possibility."
"Why don't I go get them, and you can ask them yourself?" said Isabel, standing up on slightly shaky legs. She headed off up the stairs.
"Son, I'm proud of you." beamed Dad. "And your sister. You know me and Evelyn, I still have a sex drive, and she'll accommodate me sometimes, but it's different. My old body, and hers. She's like an old friend, and I do love her. But it's different with family."
Isabel came back with the girls in tow. They wore nightclothes, pajamas for Emily and a satin teddy on Tessa, looking adorable. They sat down at the table with us.
"Cool, can I have a drink too?" said Emily eyeing the whiskey.
"Just a sip." said Isabel.
"So, we've just explained to Grandfather about everything we've been up to recently." I told the girls. "Sexually."
"Is it true what Dad said about you, Grandfather?" Tessa piped up. "That you did it a lot with Mom when she was our age?"
"That's very true." he admitted. "And we still do, sometimes."
"And did the incest not bother you?" asked Emily. "Or did it turn you on more, doing it with your daughter, the thrill of the forbidden act?"
Dad grinned. "You are such a smart girl, Emily. Yes, it turned me on. Hell, it still does. And hearing about what you've been up to as a family, that turns me on something fierce."
"Can we watch you do it with Mom?"
Dad and I chuckled at her frankness, but Isabel, slightly drunk, took her meaning very directly.
"Sure, honey, you want to see me fuck my Daddy like you fuck yours?" She stood up from the table, bunching up her dress, pulling it up to her waist. "Come on, Daddy, show them."
"Right here and now?" Dad gasped. He was slightly drunk too. "OK, why the hell not." He stood up and came around the table, dropping his pants. Isabel pushed off her panties and bent right over the table, between the girls. Dad got behind her.
"Wow." said Emily, staring at her grandfather's large, hard cock.
"Cool!" giggled Tessa.
Isabel gasped as her father found her pussy with his fingers, lined up his cock, and pressed it in. There was a big grin on her face as we all watched him start to vigorously fuck her, right at the dining room table. Her large buttocks made a slapping sound against him as he drove himself into her pussy.
Emily sat back, watching carefully as if studying them. A middle-aged man and his adult daughter, fucking in plain sight of his family. His face and hands, his naked hips showing signs of his age, but his thrusting cock showing his intact sex drive.
Tessa was more simply and viscerally involved, her mouth hanging open with lust, her hands touching them as they fucked. When Dad pulled out for a second to catch his breath, his cock hanging hard and wet in the air, Tessa bend forward and sucked it into her mouth.
"Jesus!" he gasped, staring down at the unexpected sight.
"Do you like that, Grandfather?" asked Tessa pulling her head back.
"Sure angel! I love it."
"Will you let me drink your stuff?"
It took Dad a moment to realize what she meant. "Sure thing, angel. That would be very sexy!"
Tessa grabbed his cock and put it back in Isabel's pussy. Dad resumed thrusting. With Tessa playing with his balls, it wasn't long before he came, suddenly and abruptly.
"I thought you were going to let my sister drink it." said Emily, laughing at her grandfather. "Too hot for you, huh? I guess we're a pretty kinky family."
"That's OK, I can still drink." said Tessa casually, sucking Dad's cock clean, then she turned to press her face between Isabel's buttocks. There was a slurping sound, and I realized she was drinking cum from her mother's pussy. Even I was astonished. I'd never seen her do that before.
"Can you fuck me too, Grandfather?" asked Tessa eagerly, lifting her head, with cum on her lips.
"Wait, wait a minute." he gasped. "I'm an old man now. I doubt I can get it up twice in a night."
"Oh, I bet we could do it." said Emily with a wicked grin.
We all moved upstairs, to the master bed, shedding clothes as we entered the room.
"Let me start with Grandfather." said Tessa, standing in front of him by the bed. We watched as they embraced, his hands roaming over her delectable curves, her large yet perky tits, pulling off her slip. They kissed and fondled each other. I was already hard, but Dad wasn't yet.
"Here, give me a turn." said Emily, standing up, naked, taking her sister's place. She put her arms around him, offered up her lips. He kissed her, his hands roaming over her small tits and pointy nipples, down her pale soft belly.
"Hmmm, OK, you kiss nice." Emily grabbed one of his hands and moved it lower, wrapping one of her own hands around his half-hard cock. "Don't be scared to touch my pussy. I bet it feels really sexy to you."
"You feel incredible, sweetheart." gasped Dad.
I glanced at Isabel, who was on the bed, legs spread, touching herself as she watched her father and daughters cavorting. I looked at Dad, and it looked like he had a finger or two inside Emily's little pussy. Tessa dropped to her knees, next to them, taking Dad's half-hard cock in her mouth.
"Do you want to taste my pussy, Grandfather?" asked Emily sweetly.
"God, yes." he gasped.
They all tumbled into the bed, and we moved from one arrangement to another. Dad kneeling between Emily's legs, licking her pussy. Emily sucking Dad's cock as he watched Tessa and Isabel do a mother-daughter 69. Dad's cock, finally hard again, jutting up as he lay back and Tessa sat down on him, fucking her father/grandfather for the first time, bouncing on him playfully. Eager for some attention on my own cock, I pulled Emily to me and slid into my daughter's pussy from behind, so that we could fuck and still watch the others. Isabel cuddled up to Dad, playing with his balls as Tessa rode him. After many long minutes, Dad finally came, with one of Isabel's nipples in his mouth as Tessa's athletic body bouncing on him. I was close behind, holding myself deep inside Emily and letting myself come.
Dad stayed over that night, sleeping with Tessa in her bed. Emily slept in ours.
With Dad's visit over, we settled back into the regular flow of our lives. School, work, cooking, sports. The sex was there, in the small parts of the day that weren't already so busy. Joe and Tessa sneaking off to suck and fuck. Emily bonding with me, often joining Isabel and I in our bed at night. The girls rarely got with each other, unless I specially asked to enjoy them together.
There were several more birthdays before the end of the school year - Emily turning 14, Tessa turning 15, Joe turning 16 and getting a driver's license.
School ended, summer vacation started. Dad came over much more often, often just to hang out. Joe went off to a summer camp. He complained that he was too old for camp, but I knew he'd have fun - what he was really complaining about was being away from his sister's charms.
One time, Isabel sat down with me and told me about what she'd been thinking about a lot recently - our kids growing up and turning into adults, that would leave someday.
"What do you think, Mike?" She looked at me tenderly. "I'm still young. I could have more children."
"You've already given me a precious son and daughter." I said. "And you know as my sister, the genetic odds aren't good for us having children. We might not be so lucky again."
"What about Dad?" she asked. "I talked to him about it. He said he'd be happy to impregnate me again."
"But it's a similar genetic roulette." I protested.
"I know. But I asked Emily to look it up for me. She did a lot of research. There's a lot of screening you can do nowadays, Mike. They can detect most defects early. I'm not opposed to getting an abortion if it's not going to work out."
"Geez. Well, if it's something you really want, I'm happy to support you. We can afford another child or two, especially when the others move out. Dad really wants to knock you up again?"
"Not only me." She grinned. "He talks about getting the girls pregnant too."
I shook my head. "They're too young."
"Well, I already talked to them about it. You might be surprised, but both of them were open to the idea. They actually do both want to be mothers. But Emily insisted on waiting until they turn 16, like I was when I had Joe. So, it's not going to happen right away."
Isabel went off birth control.
I had long talks with Emily about it. Did she really want to be a mother, at only 16? Didn't she want to have it with someone outside the family? She assured me that she loved the idea of having her grandfather's baby, she knew all the risks and medical context, and besides, she still had a couple years to change her mind.
Since I was no longer able to ejaculate safely into my wife-sister's pussy, she started to offer me her ass more often. We had proper sexual lubricant now, not the messy butter or Crisco of our childhood, so it was more comfortable for her. I was very happy, with a tight hole to fuck that I hadn't had much in many years.
Dad came by on his frequent visits, and always went off to a bedroom with Isabel. Tessa often joined in, just to help pleasure him, although he always managed to leave his cum inside Isabel's fertile and unprotected womb.
One hot summer day, Isabel was wearing a very skimpy outfit around the house. I was feeling horny, and went looking for her. I found her in the backyard. Tessa had been sunbathing, lying naked as usual, on her back, on a blanket. Isabel was wearing only a shirt, squatting over Tessa, rubbing her pussy on her daughter's face.
I went upstairs to grab the lube, then went down to join them.
"Oh, Mike!" Isabel looked up, a little apologetically. "I was feeling so horny, and Tessa was lying here looking so beautiful."
"Don't worry, I understand." I chuckled. "She is beautiful, and she never says no. It is very tempting. Go ahead, don't mind me."
As they resumed, I got between Tessa's beautiful bronzed thighs, with no tan lines. With some fingers, I felt inside her pussy. Finding it wet and receptive, I pressed my cock in and began to fuck her gently. The sun beat down on us, making us slippery with sweat. Isabel ground her pussy until she quivered with a small orgasm, adding even more wetness to Tessa's body. The slipperiness gave me an idea.
"I want your ass." I said.
"Sure thing." Isabel moved down and pushing her buttocks back at me.
"Ass?" said Tessa.
I thought about it, and realized this was a kind of sex we had never shown her. Emily had seen it, early on in her education. But I had been reluctant to do it around Tessa, not sure she would understand.
"Yes, honey." said Isabel. "Sometimes I let him put his cock in my butthole, and fuck me that way."
"Wow! Doesn't that hurt?"
"It can hurt a little at first, but I've gotten a lot of practice, and once he's inside, it can start to feel good. You know how sometimes Daddy or I put a finger in your butt, when we're eating your pussy? You know how that can feel kinda nice?"
"Yeah. But a finger is small." Tessa squirmed under us. "Can I watch you do it?"
We let her get up from under us. The blanket was a little crowded, but Isabel was still on her hands and knees in front of me.
"The secret is to use a lot of lubrication." I said, putting a lubed finger in Isabel's ass.
"Cool." Tessa looked at the lube, then put some on her finger. "Can I try too?"
"We can do it together." I grinned.
Isabel moaned as she felt both of our fingers, squirming around together in her backside. I added another finger. We took turns, with me pumping two fingers in and out, then Tessa doing the same. She laughed, as if it were a game.
"I'm going to put it in now."
"OK!" Tessa ran her slippery hand over my hard cock, helping me guide it. I sank into Isabel's ass very slowly at first, getting past the sphincter, letting her relax, and then it was a matter of working my way in, inch by inch.
"Wow!" said Tessa as I started to thrust in and out.
"This is called anal sex." I explained. "Or ass-fucking, or butt-fucking. Or sodomy."
"Ass-fucking!" she repeated, giggling. She lay down on the blanket next to us, spreading her legs, holding the lube in her left hand, lubing the fingers of her right hand, then pressing one finger into her own ass.
I casually and slowly ass-fucked Isabel, in no hurry. Next to us, Tessa was having a lot of fun playing with lube and her own ass. She got two fingers inside herself, pumping them slowly in and out. She didn't seem to be in any discomfort. I got an idea.
"Tessa sweetheart, would you like to try anal sex with me?"
"Sure!" She giggled.
I pulled out. Isabel looked over her shoulder with a look of lust and apprehension, not sure if this was a good idea. She had been 18 when she first let me do anal with her, but Tessa was only 15. Isabel lay down next to her daughter, kissing her, helping to lift her legs up high. Tessa held her legs up, exposing her pussy and ass as widely as she could. I moved between her legs, putting one finger into her ass, then another. She felt ready. I gingerly worked the head of my cock into her virgin asshole, going even more slowly than I had with Isabel. It took two minutes to get all the way in. Tessa was biting her lip, her eyes wide with surprise at the new sensation.
"That's it, I'm all the way in." I bent forward and kissed her. "Do you think you're ready for me to fuck you this way?"
"Yes, Daddy. I want to be like Mom." She kissed me again. "Do it."
The sun beat down on us. Sweat trickled down my body as I carefully thrust my cock into her impossibly tight passage. Isabel watched us carefully, and when she saw that Tessa was in no great distress, her apprehension gave way to lust. She slid one hand down Tessa's body, slipping two fingers into her daughter's pussy.
"Oh, God, I can feel you moving." Isabel gasped. "Fuck her, Mike. Fuck my little girl in the ass, I want you to come, come deep up her ass."
Within a few strokes, I did.
Two months went by. The birth control worked its way out of Isabel's system, and the pregnancy test came back positive - she had another baby by her father.
I was enjoying Tessa in all three holes now. Emily of course insisted that I do the same with her, anal sex, but for once I was able to talk her out of it - just too young, and too small. As a compromise, I told her she had to wait until she turned 15.
Summer came to an end. Joe came home from his camp, resuming his sexual relationship with Tessa. Tessa told me about when she turned Joe on to anal sex, so I knew they were doing that too. Joe never expressed any sexual interest in his mother or his youngest sister - just Tessa. I could see their bond was strong, more clearly than they could.
School started again, and the kids got busy, there was less sex. Isabel's belly started to show a bulge.
Once during the long Thanksgiving weekend, I accidentally walked in on Joe and Tessa, going at it in his room. I closed the door behind me quickly and went over to them. I always enjoyed watching them together, and by now Joe was pretty used to me watching, and sometimes joining in. Tessa was naked on her hands and knees, with Joe giving it to his sister doggy-style. They were both strong and athletic, so their fucking was energetic. It was sexy to watch them enjoying themselves.
"Did you just start?" I asked, sitting down on the bed with them and kissing Tessa, reaching down to play with her swinging tits.
"Yeah, a few minutes ago." said Joe, thrusting away.
Tessa was pawing at my lap, so I stood up to drop my pants and briefs, getting back on the bed on my knees in front of her, feeding her my half-hard cock to her mouth. Joe and I used her beautiful body together, for a few minutes until Joe gasped and shook, coming in his sister.
"I could use a fuck." I said.
"Your turn." said Joe with a grin, pulling out and sitting back.
"Do you want me on top, Daddy?" Tessa asked.
"Sure, sweetheart." Happy to let her strong body do all the work, I lay down on the bed with my cock sticking up. Tessa climbed on me and with practiced skill, took me inside her for a bouncing fuck. Her pussy was very slippery already from her arousal and her brother's cum. Joe was watching us, his cock still youthfully erect. I had an idea.
"Tessa, do you want to try something new?" I asked, already knowing the answer.
"Sure!" she giggled.
"Joe, is there some lube handy?"
"Yeah." He reached in a drawer by the bed, pulling out a bottle.
"Tessa, slow down for a minute, and lean towards me." She bent down, and I gave her a kiss. "Joe, go ahead and lube her ass, let's see if this will work."
"Oh. Wow! OK." Joe scrambled into place.
It did work pretty damn well. It took a little practice to figure out how to move our three bodies together, but Tessa took me in her pussy and her brother in her ass quite readily. There was some extra tightness, but the range of motion wasn't quite enough to get me off. Joe loved it, and Tessa moaned like crazy as our two cocks pistoned in and out of her holes. In just a few minutes, he came for the second time. Ah, to be 16 again.
Joe pulled out and went off to go clean up. Tessa continued to ride me with her wet pussy. I was close, but still not quite there.
"Tessa sweetheart, could you lift up a little? Do you think you could put me in your ass like this?"
"Sure, Daddy." She lifted up, grasping my cock, then lowered herself down, taking me in her back hole. I had never fucked her like that before, in her ass with her on top, but she didn't seem to have much difficultly. She bent forward, and I sucked one of her nipples into my mouth as she started moving up and down on me. In this position, her sphincter was gripping me tightly, clenching rhythmically as she rode up and down. That did it, barely a few bounces until I came hard up her ass.
When I told Isabel about it later, she got hot and asked me to do her ass while she used two vibrators, one in her pussy and one on her clit.
I didn't dare tell Emily about it, knowing she'd be jealous that her sister had done something she couldn't. On the occasions I got together with Emily, we did a lot of talking and hanging out before slowly moving into making out and sex. A simply straight fuck with my daughter's tight pussy was more than enough to drive me wild.
That Christmas, Isabel got her chance to try two cocks. My Dad was visiting, and we found ourselves playing cards at the kitchen table, up late at night, the bottle of whiskey out again. At six months pregnant, Isabel wasn't drinking, but she was in a good mood. With just the three of us there, we found ourselves talking about sex, and I told the story of Tessa taking on Joe and I together.
"Jesus, Mike." Dad shook his head. "That can't be right. Hell, putting in a woman's butt is crazy enough already. And she's still just 15."
"I don't know, Daddy." laughed Isabel. "It sounds sexy as hell to me." She never called him Daddy unless she was turned on.
"You've have had anal sex, right Dad?" I asked.
"No, I never have. You know I'm a bit bigger than you, and I wouldn't want to cause any woman that kind of discomfort. And my first wife, your mother, was a bit too straight to try that anyway."
"You know, we could do it." said Isabel smiling. "I mean, with you in my pussy, Daddy."
"Even though you're pregnant?"
"Sure. C'mon, let's try it!"
We gave in, following her upstairs. In the bedroom, she pulled off her clothes and lay back on the bed, lowering herself slowly being careful with the bulge in her belly. She directed us, my face between her legs to eat her pussy, Dad's cock to her mouth. After a bit of that foreplay, she declared she was ready. Dad lay out on the bed, his old but thick cock sticking up. Isabel straddled him and lowered down, moaning as his cock stretched her pussy open. With her belly, she could only rock a little while remaining comfortable, but it was enough to make both of them moan. I knelt by their side, letting Isabel suck my cock a bit, then I went for the lube, getting behind her. It felt a bit strange as I got behind her wide buttocks, as I was between Dad's legs as well. I had a perfect view of her labia stretching as she moved gently up and down on Dad's cock.
Getting some lubed fingers, and then my cock, into Isabel's ass was a slow, careful process. Finally my cock was in there. Just like with Tessa, there was a process of finding the right rhythm for our three bodies to move together. Isabel was beside herself, gasping and grinding her clit down on Dad as her hips moved, accepting the growing speed of my movements. Right there, pregnant with her fourth incestuous offspring, with her father's cock in her pussy and her brother in her ass, Isabel came, and came hard. I was right behind her, her orgasm setting off mine, as I filled her ass with cum.
When our bodies stopped buzzing, I pulled away, and Isabel rolled off Dad as well. She reached over and took a hold of his cock, big and hard and wet.
"You know, Daddy, if you want to try anal... there's never been a better time than right now."
I looked down at her ass, dilated with cum trickling from it.
"She's right." I agreed.
"Jesus. Damn. OK." Dad sat up, running his hand between her legs, petting her. "How can you take me, on your back like that?"
"No, let me get up." She got onto her hands and knees. Dad got behind her, and gingerly, unsure of himself, pressed the head of his cock into her ass. She gasped, the larger cock stretching her slightly, but she was so wet and so high on sex that it would work. Soon Dad was all the way in, fucking very slowly.
"Well, it does feel different." he said. "Hot as hell."
"Hey." I realized something. "You know, you think I'm living here with a crazy sex life with my family. But you're actually doing something I've never done - fucking your daughter in the ass. I've done it with Tessa, but she's not my daughter, she's yours."
"Don't worry about me, Daddy." said Isabel, breathing heavy. "This is for you. Just keep doing it." She managed a smile. "Merry Christmas!"
"Fucking awesome Christmas." Dad mumbled, lost in the sensation, their flesh starting to slap as he fucked harder and faster, until suddenly he cried out, coming deep in his pregnant daughter's ass.
That Spring, Isabel gave birth to a healthy baby girl, Jessie. To our friends and neighbors, Jessie was my daughter, which as far as genetics goes, wasn't actually too far from the truth.
Tessa stopped taking birth control soon before turning 16. She got her birthday present: a pussy full of incestuous spunk from Dad, her father/grandfather. She was pregnant right away, as if her body was just waiting for the moment. Joe and I were happy, since we could go back to having unprotected sex with Tessa, although she had always been happy to accommodate us using her mouth or ass.
Emily arranged to spend the summer in France, with a host family, and a few weeks going around Europe. We were a bit concerned, our unaccompanied 15-year-old daughter travelling alone, but she came back even more charged up with intellectual enthusiasm, and proficiency in Spanish and Italian, even a bit of German. Joe got a summer job as a mechanic. He'd always loved cars, and knew so much about them, it was natural for him.
Emily tested out of high school easily, got a car (a small French car - and there aren't too many of them around our part of Texas!) and a job at a video store. She made me watch a lot of French films with her, old stuff, black and white - and she knew a lot the actors and details by heart. Some of them were interesting, although I'm sure I didn't get a lot of it. I did love spending time with her, though. Sometimes we made love after watching a movie. Other times, when she was in the mood, she would join Isabel and I in bed. She usually wanted to take care of her mom first - the two of us licking Isabel's pussy together - then she wanted to get fucked. Emily liked to sit in my lap, impaled on my cock. If Emily was facing me, Isabel playing with her daughter's small back hole as we fucked. Or if Emily sat in my lap the other way, Isabel would get down and lick her daughter's clit as we fucked. Emily had exquisite French lingerie that she wore to great effect on me, and I've gotta tell you, there's nothing like having your daughter talk dirty to you in French while you're eating her pussy or fucking her.
As fall approached, Tessa's belly grew. Sex with her was delightful - her curvaceous, pregnant 16-year-old body such a temptation, Joe or I could barely resist stuffing with her cock frequently. She loved it on her hands and knees, a pillow under her to keep her belly comfortable.
Due to Emily's technical advice, we arranged detailed pre-natal testing for Tessa's baby, and it tested negative for any major birth defects.
Emily and Joe often bickered - about her little car, her smug attitude, or his "boorish Americanism" as she called it - but when Emily got tipsy on wine or cognac, she did seek him out and seduce him. Her inebriation and intelligence collided, with a logical argument for Joe along the lines of "Why settle for fucking your half-sister when you could fuck your full-blood sister?" Emily's body also began to fill out, not to the eye-catching proportions of her sister's tits and ass, but very sexy in her own way.
Tessa's baby arrived in January, a baby boy she named Toby. We had to invent a story about an unreliable, out-of-state boyfriend to tell the neighbors about who the father was. Isabel was still nursing Jessie, so she and Tessa could nurse each other babies, for convenience in a busy household, often one of them ended up with both babies to nurse.
Emily went off birth control. She hadn't changed her mind about having her grandfather's baby when she turned 16, even with the whole wide world of culture she had been exposed to. In fact, incest was now one of her (not-so-secret) favorite subjects. She studied it deeply, and would often regale me with things she had learned - the anthropology, biology, psychology, genetics, and law regarding incest. Unlike Tessa, who simply accepted that sex was something fun and secret that our family did in private, for Emily, it was a fully-conscious erotic perversion, a taboo she delighted in breaking for the sake of breaking it.
Dad was only too happy to visit on Emily's birthday and fuck her. He had rarely done it with her, so it was a treat for him, coming by often during the next couple weeks. Emily's goal was to get two loads of his cum in her pussy each visit. Getting Dad up a second time was sometimes a challenge, so she enlisted the help of her sister. Although Emily had rarely had sex with Tessa before, they worked as a team to get Dad hard, with a double-blowjob, or letting him watch as they made out or sucked or finger-fucked each other's pussies, until he was hard enough to go another round. Finally, Emily tested pregnant.
At the start of that summer, Joe graduated from high school and moved out into a place of his own, in our same subdivision. It was walking distance, but he always drove, in love with his cars, two in the garage, one at the curb.
It was that summer that Emily began her pre-natal testing at the earliest possible date. The grim news came back. Our luck had run out, the baby would be born with a crippling defect. Too many of the same genes piled up together. On the surface, Emily was detached and logical and calm, arranging an abortion. But alone with me, she cried.
Two weeks later, on the Fourth of July weekend, she had gotten over the experience enough, emotionally and physically, to start talking about trying again. We had a family BBQ in the back yard, with everyone there, including Evelyn and some friends. Emily wore her dark European clothes, hiding as usual in the shade from the hot Texas sun. She pulled me and Dad aside, out of earshot of everyone else.
"I still want to be a mother."
Dad nodded seriously. "I know you know all about the risks, sweetheart. Do you want me to try again with you?"
She looked uncertain. Something didn't feel right to me - something that hadn't felt right in a long time. I finally spoke up.
"Why should it be you, Dad? Why are you always the father? Getting Isabel pregnant again? And Tessa? And now Emily?"
He regarded me, taken aback. "Well I'm sorry Mike, I thought it was what everyone wanted. I wanted to, they wanted to."
"If I didn't know better," said Emily, "it sounds like you're jealous, Dad." She regarding me with a sensitive look.
We all stood there looking at each other, the truth of her words settling in.
"Don't be jealous, Son." Dad looked at me with a smile. "If you'd like to be the father, just say so."
"Yeah, Dad." Emily gave me a look - was that hope in her eyes? "Just say so."
The realization came to me. The passion I had felt with my sister Isabel, over the two decades we had been intimate, had shifted. I would always love Isabel and be a good and caring husband for her. But the spark, the romantic bond, the flutter in my heart was for our daughter Emily. That's why I was jealous. I wanted to be the father of her child.
"Emily, my love." I gazed at her sweetly. "I'm saying so."
Within sight of the mixed company of friends, we couldn't just fly into each other's arms, but the look into each other's eyes was intense. Dad just grinned, pleased that the situation had worked out. That night, Emily and I spent hours together, talking and touching, kissing, caressing each other until making sweet love together. I brought her to orgasm once with my lips and tongue before taking her gently, leaving a load of my cum in my daughter's unprotected young womb, not knowing if her body would be ready to catch again.
As it turned out, it didn't happen right away. There was two months of unprotected sex that summer, sometimes slow and loving and tender, other times 'quickies' or scenes with her mother or sister. Isabel was very understanding. We still slept together and had sex from time to time as husband and wife, but if I was going to spill my cum, she made sure that Emily was there with her snug pussy to receive it. Emily also enlisted the help of Tessa, as she had when getting pregnant the first time. Together the sisters would strip slowly and make out with me and each other, teasing me to maximize my arousal, to get me worked up, so turned on that I would slip into Emily's pussy and immediately started to come.
Emily was so happy when she proved pregnant, and even happier that fall, when the future baby tested negative for defects. That winter, as her belly grew, I finally knew the pleasure of fucking my own pregnant daughter.
Emily gave birth to her daughter, Sarah, just three days after her 17th birthday. Tessa turned 18, Joe turned 19. I found myself a grandfather at the surprising age of 36.
There were two more pregnancies in the family that year. Emily and I considered having another baby, but after a great deal of review of the scientific literature in genetics, Emily had concluded that we should, as a family, be trying to mix up our matches. That's how I ended up getting Tessa pregnant, and Emily chose Joe as the biological father for her second child.
After Tessa had her second baby, a boy she named Thomas, she moved with her two babies into Joe's house. To the outside world, it looked like Joe was a swell guy, taking care of his retarded sister and her two out-of-wedlock children. They kept separate bedrooms on opposite sides of his house, to keep up appearances. But our family knew they slept together every night as husband and wife, like a secret marriage. Over the next few years, Joe had a few girlfriends, but we knew they would never threaten the family. He and Tessa loved each other too much, in every way.
Emily had her second baby, a daughter she named Caitlyn.
As the children grew up, we learned the traits that a pre-natal test can't tell you. Toby was "developmentally challenged" like his mother, Thomas was a regular all-American boy like Joe had been. Sarah was gifted and introverted like her mother, Caitlyn was more artistic and outgoing.
Although the family was split between two houses - Joe and Tessa with her two kids, myself with Isabel and Emily and three kids - the short distance between our houses meant a lot of gatherings with the whole family present, the convenience of being able to take care of each other's kids. Just as when we were raising our first batch of kids, the households were often totally overwhelmed by the logistics of parenting - school, hobbies, their friends, sports. There often wasn't much energy left over for sex in the daily grind, so it was more common on weekends and holidays.
Joe was comfortable getting regularly laid by Tessa. Tessa loved to be with Joe, but she also came to our house to have sex with me, Isabel, and sometimes her sister. She developed into a stunningly beautiful woman, with a powerful sex drive. She also enjoyed anal sex far more than her sister or mother ever did. With the appropriate preparation, she was even able to take my Dad's cock - her father/grandfather - in her ass.
I sometimes slept in Isabel's bed, sometimes in Emily's, and sometimes the three of us would sleep together - entirely depending on the women's moods and cycles and the day-to-day logistics of the household. As the years went on, Isabel's sexual tastes settled on her favorite things: long sessions of straight sex with me, and oral sex with her daughters.
In 1999, I turned 40, Emily gave me a birthday present: her ass. After years of watching her sister get fucked in the ass by me, Joe, and even my Dad, she had decided that this was an experience she wanted to try to learn. Seven years had gone by since the time she gave me her virginity for my 33rd birthday, and now it was her virgin ass. She had already been practicing for some time with a lubed dildo, so that when she took me to bed after my birthday dinner, she was ready. After warming up with oral sex and some straight fucking, I got the head of my cock through her sphincter and managed to last around a minute of thrusting before coming.
She got more comfortable with it over time, although it never became a big part of our sex life. At least now my Dad wasn't the only one to have ass-fucked his daughters.
I always knew that the next generation would get swept up into the sexual traditions of our family. I didn't realize how young it would start.
When the oldest, Jessie, was 13, it came to light that Tessa had been regularly "tickling" the young girls with her tongue, and had been since before puberty. The girls liked it, Tessa liked it, Tessa understood that sex within the family was OK, and nobody had ever told her not to - so she did it. It also came to light, a bit more shocking to me, that she did the same for her two boys, Toby and Thomas, as soon as they began to have erections.
We had a family meeting, with all the adults besides Tessa, to decide what to do. We had always avoided any inappropriate touching before the children were adolescents - young adults at least 13 years old. And we had always avoided mother-son contact as well. But nobody had explained these rules to Tessa. We decided that there would be less harm in letting her continue, than in trying to convince her that her gentle, affectionate actions were "bad".
We also decided to start Jessie's education right away. At 13, without knowing much about sex or her family history, Jessie was in danger of concluding that the licking from her aunt (and, actually, half-sister) Tessa was some kind of molestation. So, Isabel and I taught Jessie about sex, very gently, just as we had taught Emily and Tessa a generation before.
Over the next two years, very gradually and gently, Jessie taught her cousins/half-brother Toby and Thomas about sex, and finally Emily and I taught her daughters, Sarah and Caitlyn.
Mostly, the kids' sexual experimentation goes on between them, not involving us adults. The girls lost their virginity early to their cousins/half-brothers, after Isabel put all of them on birth control. Over time they have experimented more with the adults, and I've had my modest cock in each of the girls, gently.
I've been thinking back to something Emily said years about - our family tree is tangled. I thought about it, and realized I had never drawn it out. A normal family tree looks something like this:
Our tree looks very different. I tried to draw it once, and it came out like this:
I turned 48 this year, Isabel 49, Emily 29, Tessa 30, Joe 31. Trying to remember everyone's age in a family our size is tricky. Counting backwards, I figure Jessie at 16, Toby 15, Sarah 14, and Thomas and Caitlyn at just 13. Dad, bless his soul, is still with us, just shy of turning 70.
The times we all get together, a few times a year, it is a family experience. Isabel is usually the only person who doesn't join in the parties, as she still avoids sexual involvement with her son Joe. Unless Joe isn't there, in which case Isabel is happy to join in, mostly oral sex with all the youngest.
It's now Thanksgiving, an extra-long weekend, no work or school, a great time for a family sex party. We just finished one lovely such gathering. Some family traditions have formed about the rules and the order. It starts with the older adults affectionately kissing and undressing the young adults, then performing oral sex on them. Warmed up, the youngest get together for oral and straight fucking, in a group as the adults watch. Then it's the youngster's turn to move around the group and provide oral sex to the adults. Finally, we all move into the center and the younger and older ones get to fuck. After that comes the anything-goes stage, family members fucking each other in groups. Finally, at the end, is the anal stage - those old enough can get ass-fucked.
Anal is very specific. With our reasonable-sized cocks, Joe and I can do our sisters or adult daughters, and Jessie at 16 has started accepting us in her ass as well, as long as we're gentle. My Dad, his cock still large as an old man, is only allowed in Tessa's ass. Sarah, at 14, now lets Toby and Thomas, with their boy-sized cocks, practice in her ass, but only at our family parties.
Tessa is the one wildcard, willing and happy to do any sex act with anyone, anytime. She's tried everything the family has thought of - a strap-on fuck from her sister, a fist-fuck from one of the younger girls, two cocks in her pussy (a strange sensation, speaking as one of those cocks), or three cocks in her mouth/pussy/ass. We knew Tessa was sucking off her sons, and Emily had tried it as well, the kinky novelty of sucking young cock appealing to her. But I was still blown away with surprise when, at our first family sex party, Tessa lay back and spread her pussy for her young sons to fuck. Emily, our family's scholar-in-residence on all matter of incest, loved it. She went right over to caress Tessa and Toby as they fucked, masturbating herself as she watched them, almost coming when Toby did, then taking his place to suck his young cum from her sister's pussy.
Since then, it's become a tradition that our parties conclude with Tessa on her hands and knees or draped over a bit of furniture, spreading her buttocks, inviting any male that can still get it up to do her ass - her father/grandfather, brothers, uncles, even her sons. It's a little disturbing to me, perhaps because I didn't grow up with it. Each generation seems to be getting more uninhibited. The girl-girl sex didn't start until my children's generation, and the mother-son didn't start until my grandkids. What will happen by the time I'm an old man - the men and boys start fucking each other?
Tonight my daughter Emily and I cuddle up together in our bed to sleep, with our daughter Sarah next to us. The party has us totally drained. I managed to come three times: in my 13-year-old granddaughter Caitlyn's mouth, my 14-year-old daughter Sarah's pussy, and my 16-year-old niece-cousin Jessie's ass. As I drift off to sleep, I am thinking of the pleasures of growing old with such a tangled tree.
The End
