This is one of Puppy's Stories.
Part 1 was the build-up without any incest...
One morning after the kids had gone out the door, and we were sitting at the breakfast table, Beth turned to me with a new and disturbing subject.
"Mike honey... I want to tell you. I don't feel right about something. We always have to be so careful around the kids. You know, they're not stupid, they know about sex. They've had sex ed in school, and I know that Julie isn't a virgin because of that boyfriend last year. Remember him?"
"Sure I do. As hard as it is for me to accept, they are sexually mature, not little kids anymore. But what are you saying? We can't have sex in front of them."
"Well.... why not?" She had a mischievous twinkle in her eye.
I stared at her. "Well, lots of reasons. It would make them uncomfortable. They would think it was weird, maybe even icky to see their parents having sex. And what if they told someone?"
"They wouldn't tell. Come on, if you had weird parents who had sex openly around the house, would YOU tell anyone?"
"Good point. Last thing in the world I would do. But look Beth, you have to consider how they'd feel."
"How do you feel? Assuming the kids were fine with it. Would you be OK fucking me with them around?"
I thought for a while. "I guess so. I mean, if they're OK with it. It should would be nice to be able to have sex without being paranoid all the time. But it would never happen - they'd wouldn't want to deal with it."
Beth looked at me and smiled. "Aha. Think you know so much? As it turns out, I already discussed it with each of them, separately."
"What?! What did you tell them??"
"Well, Mr. Know-It-All, it may come as a surprise to you, but they were both already well aware of the fact that we've been having a lot more sex recently. These walls aren't that thick, you know. So I talked about them with it. At first, you're right, they thought it was icky, but then I had long conversations about being sex-positive, that we are humans with sex drives just like them, and that it's natural. Julie even said it would be fine if we had sex without hiding it."
"You mean... she... right in front of her?"
"Well in the same room, you know. Basically, yes."
"I don't know. I'm not so sure it's a good idea. Call me old-fashioned, but there's something a little bit too strange and perverted about having your kids watch you have sex."
"Fine, honey." She just smiled, and let the subject drop.
I thought that was the end of it, until that afternoon. I learned later that my wife had planned the "incidents" completely, but at the time I was freaked out. I came home, and Beth was horny as hell when she met me at the door. I tried to lead her upstairs, but she just tossed off her clothes and lay down on the floor. She held her pussy lips wide and smiled, and I couldn't stop myself from unzipping and getting down to fuck her.
We were part-way into an excellent fuck when I heard the front door open behind me!
"Oh, hi Mom, hi Dad." said my son's voice. I froze. "Don't mind me, keep doing what you're doing." He walked right past us and went up to his room.
I looked at Beth with my eyes wide. "I told you so!" she said giggling. "Now keep fucking me!" Slowly I started again. Soon was rock-hard again and really getting into it when I heard the door open again behind me.
"Oh!" said my daughter Julie's voice. "You guys are fucking again. Seems like you're always at it." She walked right past us and into the kitchen.
"See?" said Beth. This time, I was amazed and a bit disturbed to find that rather than stop, I was actually turned on. I fucked Beth even harder, even as Julie came out of the kitchen holding food, and stared at us for a minute. I looked up, and the look on her face was one of calm amusement. Beth's pussy convulsed around my cock, and I came, pumping her pussy full of sperm. Julie giggled, then turned to go to her room.
That evening, as we were all sitting in the living room around the TV, Beth took it a bit further. It was a commercial break, and she was cuddled next to me on the sofa. Her hands were stroking my crotch, which was making me slightly nervous already, then she said "I wanna suck on your cock."
I looked at the kids. The kids looked back at me.
"I.. uh..."
"Go ahead guys." said Mark. "Don't mind me."
"Yeah, go ahead. I mean, you're like married and all." said Julie.
Beth smiled and unzipped my pants. She slid down the sofa to the carpet, and slurped my cock into her mouth happily.
My head was spinning. The kids weren't paying much attention, mostly watching the TV, but during the next commercial break they were definitely staring at us. I looked at Julie, and saw her watching Beth's head move up and down on my cock. She's looking at my cock, I realized. My daughter is looking at my cock. She's watching her own mother give head. She watching her father get a blow-job. I couldn't quite wrap my head around it.
Both kids turned their attention back to the program. Beth stopped, stood up briefly, and pulled her dress over her head. She kept her bra on, but pulled her panties off, then climbed back onto my lap, lowering herself onto my cock.
"You... sure..." I looked at the kids. "You're alright with us.. "
"Of course Dad. It's not like we haven't seen Mom naked." said Mark.
"And you know we're not virgins." said Julie. "Go ahead and fuck. It looks nice."
We kept fucking. In fact, it seemed as if Beth was trying to give them a show. She fucked me sitting in her lap, she got on her knees and had me fuck her doggy-style, then put me on the floor and bounced on top of me, her bra removed, her large tits bouncing. She made absolutely no attempt to be quiet, but cried up her orgasm noisily when it finally came. I was incredibly turned on, but for some reason I couldn't come. I think it had to do with the kids watching! A part of my brain still wasn't coping with it.
Beth rolled off, pulled her clothes back on and watched the rest of the show with the kids as if nothing had happened. They went off to their homework, and I took Beth upstairs to our bedroom.
"That was fun!" said Beth. "It looks like something is still bugging you though." She looked at my still-hard cock.
"What did Mark mean, he's seen you naked lots of times?"
Beth sat down on the bed. "Well, OK. It's time I told you. Sit down." I sat down. "Mike, honey, you know how parents need to have "the talk" with their children."
"The Talk, where you explain to them about sex?" I asked.
"Right. Only when I gave each of them the talk, over the past few weeks, I've done a bit more than talk."
I looked at her in amazement. "Like what?"
"Well, I talked to each one separately, so they wouldn't be embarrassed to ask questions. For starters, I got undressed, and we went over the names of all the sexual anatomy."
"You didn't."
"Oh yes we did. And I had them touch my body to explain erogenous zones."
"You.... what?! Didn't they think it was weird?"
"A little at first. But I helped them relax and get over it. They were both really curious actually, after they got over the embarrassment, they thought it was fun."
"They put their hands...."
"All over my body. And I gave them kissing lessons."
"Kissing?!"
"It's an important part of sex, you know. Just some parental guidance in case there's things they don't know yet."
"Kissing... with tongue?"
"Of course."
My head swam. I tried to picture Beth French-kissing Mark. It was so perverted, I was simultaneously horrified and... I had to admit, since my cock was stirring.... a little turned on. Then I imagined Beth and Julie kissing. Deeply. My cock got even harder.
"I see you like the idea. Let me tell you what else we did."
"Go on."
"I showed each of them how to rub my clit - how to masturbate me. Mark really like sucking my tits while he did it. Julie preferred kissing. I think kissing is her favorite."
"Don't tell me you had sex with them."
"Well not really sex. Just mutual masturbation, really. As an educational thing. I mean, I am their mother."
"And you remained detached through this? A parental distance?"
"Detached, hell no. By the second lesson, I had an orgasm with each of them. The third lesson, I instructed both of them together. It was good for them to work through their shyness with being naked in front of each other."
"They got naked?!"
"Well, sure. You can't learn about sex with your clothes on! After some prodding, we got Mark to show us how he masturbates, and we showed him how we do it. Each of us came with the other watching."
"God Beth. I can't believe it."
"You can't, but it's true, and I can tell you're turned on. Come up here and fuck me."
I was hard as a rock, Beth was wet and ready, and I slammed into her heavily.
"You want it, don't you." she said in my ear. "You want me to go all the way. You want me to have sex with the kids."
"No, that's sick." I said, but I didn't stop thrusting.
"You want it, but you won't admit it." she said smiling. "You want to see me go down on them. You want...."
My body tensed and I was coming hard into Beth.
"I knew it." she said. "I want it too."
The rest of that week, we were all busy with our normal lives, but there was definitely no longer any attempt to hide the sex between Beth and I. Mornings were too busy for sex, but evenings usually found Beth and I having a fuck somewhere. Sometimes one of the kids was around, sometimes both. Sometimes they just walked past us with some comment like "Go for it, you guys." By the end of the week, I was finally started to get used to it.
Saturday morning, Beth got up and rounded up the kids. With the morning sun streaming into through the window, Beth came back with both kids in tow and they all sat on the bed. The kids were in their underwear. Beth had a robe on, which she took off as she climbed into bed.
"Alright kids. You know I've told your father about the lessons I've been giving you."
"Uh-huh."
"You're sure you're OK with these lessons?" I asked, looking at each of them carefully.
"Sure. It's important stuff to learn." said Julie. She was so pretty in the morning light. Her body wasn't as curvaceous as her mother's, her breasts a little smaller, but she had a face that could stop traffic.
"OK. Let's review." said Beth. "First, let's get naked." The kids tossed off their underwear casually. My eyes were on Julie's body, her nipples small and pink, the tuft between her legs trimmed short but not shaved.
"Kissing." said Beth. "Let's see if you remember. Mark first."
I watched as Mark leaned forward, and kissed Beth. It started delicate, then rapidly moved to a hot, heavy kiss with lots of tongue. His cock was starting to stir.
"No problems there!" said Beth. "Now Julie."
Julie leaned forward. I drew in my breath. Julie gave me a glance with half a smile as if she was amused by my reaction, then crawled forward and sat in Beth's lap, facing her. They locked lips, and it looked serious. Julie put her hands around her mother, pulling their bodies together, their tits touching. Julie broke the kiss to run kisses along Beth's neck, her earlobe, and back to her mouth.
"That's it." said Beth. "Julie, you're an expert. So far you've practiced kissing with me, because I have the experience to teach you, but you will probably want to learn how to kiss men and boys, not just women. They are different. Do you want to practice with your brother and father?"
Julie gave each of us a look, slightly shy, and nodded her head. She crawled out of Beth's lap and over to Mark. Mark stared at his sister's lips. Slowly, they leaned in and began kissing, very softly at first, then with more and more passion. Beth reached for my cock, still under the covers, and felt how hard it was, smirking at me as I watched our children. The kiss grew, their hands found each other's bodies, and they started heavy petting.
"Enough." said Beth. "Let's keep some focus here. Julie, you've obviously got the hang of kissing a boy. Your father is next."
Julie was eager as she scooted over to me, and pouted her impossibly perfect lips. She waited. I leaned in and found myself pressed against her delicately soft lips. Her tongue slipped into my mouth, and I was lost. I pulled her close, and I could feel the heat between our bodies.
"It tickles." she said, pulling back and touching the stubble on my chin.
"That's one differenced in kissing a man." said Beth. "OK kids. We already covered masturbation in our last lesson. But kissing and masturbation don't teach you much about sex. The next lesson, if you're ready, is oral sex."
The kids looked at each other. They both nodded. I think I gulped.
"OK. Let's start with giving oral sex to a man, since I can provide instruction that way. Mark, you can be our test subject. Unless you're also going to want to learn to give oral sex to a man?"
"Uh, no." he said.
"Suit yourself. Come here and lie down." She patted the bed. Mark lay down, his cock rock-hard and sticking up. Julie and Beth sat on either side of him, and leaned forward. They put their hands on his cock, and started with gentle stroking.
"It's good to start gently, especially if the man is already hard." said Beth. "Like Mark here." She leaned forward and ran her tongue along the underside of Mark's cock, then around the glans. Mark moaned. We watched as Beth teased him for a couple minutes. "It's good to tease the man first. That way, when you suck him all the way in, it's quite a pleasant surprise after the anticipation." She demonstrated by sucking Mark suddenly deep into her mouth.
After a minute, she pulled back, and offered Mark's cock to Julie. Julie apprehensively licked around the end of her brother's cock, then sucked gently. Beth scolded her, and the two of them passing Mark's cock back and forth, refining Julie's attempts.
I stared. My wife is sucking off my son. I thought. My daughter is sucking off her brother in front of me. Julie's firm tits barely wiggled as she sucked up and down vigorously on Mark's cock. Mark made noises like he was about to come, and Beth showed Julie where and how to squeeze to stop the orgasm.
"Cum is an acquired taste." said Beth. "You may not like it at first, but it is a lot nicer for the guy if he can come inside your mouth. It's your personal decision how you want to handle it. Here, it looks like he's about to come."
"Ummm-hhhm!" said Mark as Julie sucked his cock hard.
"OK." said Beth, "let me." Julie let Beth take over, and Marc came hard in his mother's mouth. Beth pulled her head back and let the last squirt ooze onto her hand. She raised her hand to Julie. Julie stuck her tongue out and licked.
"It's kinda sweet." said Julie, licking more. "Oh. It's kinda bitter on the back of the mouth."
"Yes, it depends on where it touches your taste buds." said Beth. Julie kept licking until Beth's hand was clean.
"Next!" said Beth. "Oral sex on a woman. Mike, do you want to show the kids what to do using me as a model, or should we use Julie?"
"Me!" said Julie quickly, then giggled. "Uh, I mean, Mark should learn how to do a girl first."
"You're right." said Beth. "Mark, roll aside. Julie, lie here and spread your legs, wide but not too wide for comfort." Mark and Beth leaned in to get close, their faces inches from Julie's pussy. I also scooted over to get a close view.
"You remember the importance of the clitoris, from our masturbation lesson." said Beth. "Here, you can stimulate the clitoris in more ways with the tongue, but the fingers are also useful, to spread and heighten tension on the inner labia." She spread Julie's lips apart. Inside was beautiful - waves of pink velvet, sensuous folds within folds. "Each woman is different, so you'll need to try a variety of approaches and learn which she likes best, by listening to her carefully."
Mark nodded. Beth leaned forward and began licking Julie's labia, then got busy on the clitoris.
Julie is getting head from her own mother. I thought. Beth is sucking off her own daughter. My head spun at the sheer perversion of it. Mark looked like he couldn't wait to try.
"OK Mark." said Beth. He got between his sister's naked legs and started licking. Julie made quiet noises of pleasure. "More gently at first... now a little higher... that's better." Beth showed him how to keep the labia spread and lifted slightly, making the clit stand out. He seemed to get the hang of it quickly. Julie's noises became moans.
"That's good!" said Beth. She scooted up to Julie's side, leaving the task to Mark. She kissed Julie, and held one tit toward me provocatively. I got the idea and gently sucked on Julie's tit while mother and daughter kissed. Beth broke the kiss. "There's no pressure, sweetie, but see if you can have an orgasm. If he's doing a good job, you might be able to." She went back to kissing Julie. After a while we switched, with me kissing my daughter and Beth sucking on her tits. Julie lay back, the center of attention, and moaned quietly.
After a long delicious time, Julie came. There was no mistaking it - the lurch of her hips, her tongue suddenly going still in my mouth. We let her lay there and relax for a minute. The sexual tension in the room was thick.
"Congratulations Mark!" said Beth. "OK, group practice time. Julie, you don't have to practice on me unless you want to learn about having sex with women."
"Uh.. I think I do wanna try that." said Julie. "At some point. Right now I think someone needs to practice on Dad. I think I should."
I was painfully hard, having watched this whole spectacle with no release. Julie, my sweet, beautiful 17-year-old daughter, came to me and took my cock in her hand, a couple strokes and this her little tongue was moving around. I was delirious with pleasure.
"Be careful, he's probably close to coming." said Beth. "Unless you want to try having a lot of cum in your mouth. Now Mark, let's see if you can apply what you're learned from your sister with an adult pussy." She spread her legs, and Mark crawled over and got busy.
Sure enough, I exploded too soon in Julie's mouth. She did her best to contained it all, but she didn't know to pull her head back and choked a little. Beth was also on a hair trigger, and came loudly from only a couple minutes of Mark's attention on her clit. Probably boosting the kid's confidence, I thought.
I motioned for Julie to climb up and sit on my face. She smiled and complied. Mark was encouraged to climb up and plant his cock in Beth's mouth, and we gave enthusiastic head to our children. If my brain had been still working, I might have questioned exactly what this lesson was supposed to teach them at this point! But we were past logic, and into pure lust. I slid a couple fingers into Julie as I ate her beautiful little pussy. Mark vigorously thrusted into Beth's mouth. We kept going until each of them came again, then they toppled over and we all hugged in a heap.
"Who's hungry?" said Beth.
There was a unanimous chorus, and we all went downstairs for a big breakfast.
I forgot my lust while we devoured the food, but as soon as it was over, I suddenly realized that I had only come once this morning, that my wife and children were in front of me naked, and that I had endured an enormous amount of sexual provocation.
"I... I'm sorry, I'm still so turned on." I said.
"Why don't you fuck me then?" said Beth.
"Yeah, why don't you fuck her?" said the kids, still eating.
Why not indeed? I sat up, and so did Beth. She leaned over the breakfast table for support, and I slid my hard cock into her to start a pleasant, steady fuck. The pussy of the woman I loved so much, the pussy I had gotten pregnant all those years ago, that bore these beautiful children, these fine young adults. Leaning over the table, Beth's tits swayed over the food, her nipples brushing past the syrup and the butter. Mark took the last bite of his pancake, and pulled one of Beth's nipples right into the butter. He looked at her for reaction, as did Julie, seeing how she would respond. This was sexual contact outside the excuse of a lesson.
"Oh yes. Please play with my nipples." said Beth. "Play with them while your father fucks me."
The kids both smiled, and leaned forward. Julie kissed Beth, and Mark grabbed butter with his hands and gripped Beth's tits. He was doing something I couldn't see with her nipples, and Beth was moaning into Julie's mouth. Mark pulled the nipple to his mouth, sucking the taste of butter off it, and Julie did the same with the other nipple.
This sight was too much for me, Beth with her children oiling her body and making out with her. I came hard in Beth's pussy.
"Thanks for helping, kids." said Beth as we sat down again. Breakfast was over, and we all fell into our usual roles of cleaning up. In fact, it turned into a totally normal Saturday, as if nothing had happened! But I sure felt different. For one thing, I wasn't looking at either of my kids in the same way. I wondered how they felt - were they really as happy and casual as they seemed? How would this affect our normal family life?
Saturday night was also normal - Julie went out to hang out with her friends, Mark went to a movie with his. Beth and I cuddled in front of the TV. I was asleep even before the kids came home.
Sunday morning I woke up to the feeling of Beth's mouth around my cock.
"Mmmmmm..... what a nice way to wake up." I said, rubbing my eyes and reaching down to pat her head.
"I thought you might like it." said Beth's voice... from next to me on the bed. I blinked, and looked down, trying to focus. My daughter's head was bobbing on my cock. She wore a bra and panties, but was otherwise unclothed. She lifted her head up long enough to say "Good morning Dad!" then went back to steady sucking. I was still half-soft, but getting hard fast.
"It looks like she's getting quite good." said Beth approvingly, watching Julie's lips moving on my cock. She reached for one of my hands, and pulled it between her legs to her crotch. I expected to feel the heat of her pussy. What I didn't expect was feeling other fingers - Julie's fingers - already in Beth's slit.
"She's fingering me while sucking you." said Beth. "Isn't she good?"
I just lay back and enjoyed it. My right hand reached down to hold Julie's head - like I had to touch her to believe it was really happening, the other hand felt her frigging her mother's clit. After a long delicious time Julie raised her head.
"Mom, can I, uh, I wanna practice on you. If it's OK."
"Sure it's OK honey. I know I'll love it, and I bet your father would really love to watch."
"He would?" Julie looked at me.
"Yes, most men love to watch women having sex." said Beth. "You've probably heard guys talking about it."
"Yeah, but... that's like, fake lesbians in dumb porno movies. With fake tits."
"You're much more beautiful than any porn star." I told her. "And yes, it would turn me immensely to watch you with your mother."
"Aaaaah, Dad." said Julie giggling. "Alright." She scooted over in the bed, and gingerly approached Beth's pussy. I rolled around to put my head down for a close view. Julie stuck out her tongue and ran it over Beth's clit. Beth moaned. Julie pulled her tongue back in and seemed to be considering the taste. Then she started again, planting her mouth right over Beth's clit, sucking it into her mouth.
"Oh!" cried Beth. "That's... good... honey, just a little intense."
Beth stopped to giggle, then went back to feasting on Beth's clit. I stared for a while, then went up to kiss Beth.
"You are such a sexy woman Beth. I am so lucky to have you as my wife."
"I'm sex-crazed, aren't I? Her mouth feels so good, but I'm even more turned on because it's her."
"Our darling girl."
"Our darling baby girl, not a girl anymore."
I got down next to Julie again. "Here - let me have a turn. See, you can pull her lips upwards, like this... and her clit is more sensitive." I sucked Beth's clit for a minute, then let Julie take over.
"Can we do it together?" asked Julie.
We put our heads side by side. I used my lips to pull Beth's labia taut, and Julie centered in on the clit. Beth was going crazy, her hips starting to move. Then we switched. Somehow our tongues collided, and we found ourselves kissing, the taste of Beth's pussy filling both our mouths. Julie's tongue danced hotly in mine.
"Hey you two. Don't stop."
Julie took over giving head, and I sat up, running my hands down Julie's body. The bra was just in the way, so I took it off, followed by pulling off her panties, slick with her own arousal. I pinched her nipples gently with one hand, running my other between her legs. She parted her legs slightly - to give me access! Taking the hint, I rubbed around her pussy lips, then slid a finger inside... then two.
"What are you doing down there?" asked Beth.
"I'm fucking her with my fingers. I've got two fingers in her hot little pussy."
"That's good. Julie honey, put some fingers in me too."
I watched Julie slide a couple fingers in, then another, then all of them. I finger-fucked Julie, she finger-fucked and sucked Beth's clit. Beth moaned, and came quietly.
"I did it!" said Julie beaming.
"You beautiful girl." said Beth panting. "Come up here and kiss me."
Julie slid up Beth's body, they breasts pressing together, then locked into a deep kiss. They hips pressed against each other, Julies legs spreading to press her pussy against her mother's. I reached between their legs and fingered them both.
"69 with me." said Beth.
Julie moved around and lay completely naked on Beth's body. They settled together comfortably and mouths found pussies. Julie's hand found my cock, and she gently stroked it while she slurped her mother's post-orgasmic juices. My left hand went between Julie's legs, right next to Beth's mouth, and back into her pussy.
"What, another lesson?" said Mark's voice from the door. He stood there in his underwear, ogling his mother and sister naked and 69ing.
"Yeah." said Julie lifting her head. "Come over here and let me 'practice' sucking your cock."
Mark grinned and dropped his BVDs on the floor as he strode forward. He climbed right onto the bed, and Julie had her mouth open and ready for him. I was amazed again at how comfortable they seemed, how natural it was for them. Mark's cock slid into his sister's mouth, she rocked her head, and he started a gentle fucking motion. I felt Julie's pussy contract a few times around my hand. She's so turned on, I thought, riding her mother's face, having her clit licked and sucking her brother's cock.
Julie's face was still right above Beth's pussy, one hand playing with her mom's clit. Mark's cock slipped accidentally out of her mouth, and slapped against Beth's pussy lips. Julie sucked Mark's cock up with her mouth, and went back to giving him head, then his cock slipped out again. This time Julie left it there, lying between Beth's labia. She rubbed his cock against Beth's clit, playing with their flesh.
Julie looked up at Mark. Mark looked back at her. Both kids looked at me. We stared down at Mark's cock, large, incredibly hard and erect, resting on Beth's pussy. Finally, it was Julie that spoke.
"You wanna fuck Mom?" she asked.
There was a tense silence. Mark nodded.
"Mmmmm, do it." came Beth's voice, muffled by Julie's pussy. I nodded.
Julie got a serious look on her face, spreading her mom's pussy lips wide and aiming her brother's cock in. She turned her head to one side so that his hips were free to move forward. We watched as his cock sank slowly, deeply into Beth's pussy.
"That looks so sexy." said Julie. "C'mon, fuck her."
Mark slid out then back in, then started picking up speed. I could tell that despite his length, more or less the same length as me, perhaps a little skinnier. he was bottoming out. He looked really into it, his eyes half-closed, concentrating on the sensation.
"Oh, I think I'm gonna come!" said Julie. I renewed my attention to her pussy, and I could feel Beth's mouth going crazy on her clit. Suddenly Julie tensed up, went quiet, then moaned and rolled off Beth's body. Mark took the opportunity to lean forward onto Beth's body. Their fucking got more serious.
"Look at them go." said Julie. She cuddled against me, in post-orgasmic glow. I hugged her body, one hand found a tit and the other felt her slick wet crotch. We watched Mark and Beth fucking, which they were doing with intensity. At one point Beth started recommending different position, and we watched them go through them. They fucked with their legs scissored together, they fucked with Beth's legs over his shoulders, they fucked with Beth on her side, they fucked doggy-style. They stayed in that position the longest, Beth's wide hips wiggling, Mark driving his cock as deep as he could.
"It feels so good." said Mark. "I don't know why I haven't come."
"You're probably just nervous." I said.
"You want to fuck me?" said Julie.
I looked at her with surprise. Mark looked at her with surprise.
"C'mon, why not?" asked Julie. She lay out on the bed and spread her legs.
"Go ahead, fuck your sister." said Beth.
"I know you want to." said Julie. She stuck her tongue out at him. "You... motherfucker!"
"You hot little cunt!" he said, laughing at her. He pulled away from Beth and fell on top of his sister, wrestling with her. The wrestling turn to kissing, and his hips got between her legs.
"Wait, I wanna see this." said Beth. She scooted around and put her head by their hips. "Pull back a bit, Mark. I'm going to aim your cock. I wanna watch it go in."
I watched as well. Beth grabbed his cock with one hand, and spread Julie's labia with her other. His cock looked too big for Julie's little pussy lips, but after minute of gradually pushing deeper and deeper, he was all the way in, buried to his balls in his sister's pussy.
"That is so, so, fucking hot." said Beth. "I need to be fucked NOW." She lay down right next to Julie, their hips pressed against each other, one arm around Julie's neck, her arm like a pillow. I came around to oblige her, sinking my hard cock into her more-than-ready pussy. Mark started thrusting into Julie, and I matched his strokes into Beth. Both women gasped softly.
We settled into a nice solid fucking session. Mark and I fucked them, side by side, mother and daughter, wife and sister, through a whole range of passion. I sucked on Beth's tits while we fucked, and Mark sucked on Julie's, then we switched and sucked on the other pair of tits. I really liked kissing Julie while fucking Beth, there was something even more perverted about it.
"I'm gonna come!" said Mark.
"Go ahead, come in my pussy." said Julie. "I'm on the pill."
I stopped thrusting. Beth and I turned our heads to watch. Mark's body thrust hard, then froze, Julie's hips arched as she took his cock deep. We watched wide-eyed as Mark's body trembled slightly as his cock pulsed, pumping his cum deep into his sister's pussy.
"That's so... beautiful." said Beth. "My darlings. Let me clean you up."
I pulled out of Beth to let her move. She crawled around towards their crotches. As Mark pulled his cock out of Julie, Beth gave his cock a quick suck to clean off their juices, then fastened her mouth on Julie's pussy.
"Oooooh!" said Julie. "She's... she's licking up Mark's cum."
"You mother does love cum." I said. "I guess she likes it so much she'll even drink it from your pussy."
Beth slurped and sucked, trying to crawl into her daughter's little pussy. Finally she raised her head.
"Who needs more sex?"
"Uh, I just came." said Mark.
"Yes, and you've already had two pussies and a mouth on your cock." said Beth. "I've been pretty well fucked. Your father hasn't cum yet at all. Julie, how about you?"
"I loved my orgasm, then one you gave me. But I only got a couple minutes of Mark's cock."
"Well then." said Beth. "The natural thing would be for you to have your father fuck you."
We all paused, letting it sink in.
"Yeah." said Julie. "C'mon, Dad, fuck me. I want you to."
We all smiled, the tension broken. "You know," said Beth. "I was your age the first time your father fucked me, 17. I wasn't a virgin, but he was the first man that I enjoyed sex with. I think I got pregnant with Mark from that very first time." She was moving out of the way to let me crawl between Julie's legs.
The image flashed across my mind of Beth, pregnant, then a moment of terror as I imagined Julie, pregnant, pregnant with my child. A second later I remembered that she had just said she was on the pill. I tried hard to relax and go with the flow, as if fucking my daughter was the most natural thing in the world. I lay above her, looking into her beautiful dark brown eyes. We kissed, and I lowered my body
"Wow." said Mark. "I gotta see this." He scooted around for a good view of Julie's pussy.
Beth's soft hands held my cock, lining it up with my daughter's adorable little pussy. Her inner labia were tickling the head of my cock, then I was sinking in slowly.
"Mmmmmmm." I moaned, feeling her tight pussy walls around me for the first time. Julie was silent, a look of concentration on her face as she felt me slide in. I felt something like hitting bottom, then started wiggling in and out a bit to get just a bit deeper inside. She was smiling at me. I kissed her again, more slowly and deeply, and we started to fuck.
I picked up speed. Julie opened her mouth to moan. My hands wandered down to her naked tits, unbelievably firm for their size. She shifted her legs to allow me to go deeper, and we moaned together.
I was dimly aware that Beth and Mark were watching us. My whole world was my darling Julie, her unbelievably wonderful pussy around my cock, her smiling face, her moans of arousal. Far, far too soon, I felt myself starting to come.
"Already?" I head Beth saying. Then it was too late, I was pumping my sperm deep into my daughter pussy.
"Sorry." I managed, still laying on top of Julie, my cock softening.
"Don't be sorry, I liked it." said Julie. "Don't worry, we can practice another time."
It dawned on me. There was no going back. Beth's lust had transformed us all. There would be no rules anymore, no barriers between us, only between our family and the outside world. It had to be secret. But it was a whole new page in our family's history.
The kids wandered off, and I got into the shower to wash away all the sweat and sexual fluids. Beth came in behind me and hugged my tired wet body.
"I'll bet Mark and Julie are showering together now, like us." she said.
"You don't think they're... again...."
"Oh no, they're not fucking. I told Mark no more sex until tonight."
"Tonight?"
I tried to go about my Sunday like a normal weekend, but instead ended up taking a longer nap than usual. I woke up, spent a while reading my email then went downstairs. Beth was in the kitchen, the kids were watching TV together. It was unusual for them to agree on the same TV program, so I stared at the screen. To my surprise, I recognized one of my own porn tapes.
I walked over to them. Julie was braless under her loose shirt, and had one hand under her panties slowly moving in a circle. Her other hand was in Mark's lap, holding the erection which protruded from his opened pants. On the screen in front of them, two young women were 69ing, and a large man was fucking the one on top, occasionally letting his cock dangle into the mouth of the one underneath.
Beth came over and sat down next to us. For a minute, we all watched the screen together. I was getting hard, and Beth had a hand between her legs. The realization crossed my mind that we were watching my porn together, as a family, and that we were all getting turned on by it.
It was Julie that pressed stop on the VCR.
"Can we have sex now? I am soooo turned on."
We looked at her in surprise. She had her panties off, and had both hands holding her little pink lips apart. It crossed my mind that perhaps Beth was not the only one in the family on her weight-loss program...
"Alright." said Beth. "You saw the sex in the video, it was all threesomes. It's a common male fantasy, isn't it? To have two women at the same time." She looked at Mark and I.
"Sure." said Mark.
"Sex with three people is slightly more complicated." said Beth. "You kids will have to practice for a while before you get the hang of it. For the next hour, no two-person sex allowed." She was removing her clothes.
"Right here?" said Mark, look at the sofa and the living room rug.
"Yeah, let's fuck!" said Julie, pulling off the rest of her clothes and getting on the floor. "But if it's going to be a threesome, we need either Mom or Dad to join in."
I was already pulling off my pants and moving toward Julie's face. Mark got his hard cock lined up with his sister's pussy, and I held the tip of my cock to her mouth. Beth say beside us, naked and watching. Together, we sank our cocks into Julie, pussy and mouth. Beth reached in to rub Julie's clit, and sucked on one of Julie's pert tits. I felt Julie's eager tongue snaking around me, and the family fuck-fest was in motion.
Julie flipped over to suck me more deeply, while Mark fucked her doggy style. We rhythmically pressed into Julie's mouth and pussy, my hands on Julie's head, my fingers curled through her beautiful dark hair. Beth was giving advice to the three of us on how to stay in synch, chiding Mark for wanting to thrust too fast.
"I'm not going too deep, am I?" I asked Julie, and pulled my cock out of her mouth so she could answer.
"No Dad, it's OK." She looked up at me smiling, and opened her mouth wide, sticking out her tongue encouragingly. I slid back inside and kept thrusting.
Beth knelt by my side and kissed me hotly, her hand joining mine on the back of Julie's head. After a while she reached for my balls, fondling them as they shook with the force of fucking Julie's mouth. Then she moved away, over to Mark. I watched them kissing, and she was fondling his balls as he fucked his sister.
"I'm gonna come soon...!" he said.
"Turn around, Julie." said Beth. "Switch ends, so that Mark can have your mouth."
We pulled out, and Julie quickly turned around, presenting me with her cute backside and curvaceous hips. The tip of my cock found her pink pussy and slid in, resuming a nice gentle fuck, until Mark cried out and came in Julie's mouth, Beth holding his balls to feel them contract as they shot his sperm.
"With Mark soft for now, it looks like it's the three of us." said Beth. "Every man's fantasy, two women for you."
"Uh.... Dad?" said Julie, looking at me. "Do guys really fantasize about two women? I mean, you've only got one dick. What do you do with two women?"
"Oh, I've got lots of ideas." I said smiling, my cock straining hard and pointing toward Julie.
"Me too." said Beth. "We can start with giving him a double blow-job."
Beth took charge of the situation, which was good because I was so turned on that I wasn't thinking too clearly by then. They proceeded to give me a fantastic blowjob together, my wife and daughter, alternating between my cock and my balls, then Julie climbed up to settle her pretty pussy on my face, while Beth climbed onto my cock. I sucked Julie's clit and let Beth do all the work fucking me. I remember moving around several times, fucking Julie under me while Beth rode our daughter's face, Julie fucking me on top while Beth sucked my balls. Julie was kissing me, then she suddenly looked in my eyes with surprise.
"Mom's... uh, she's licking me! I mean.. on my butt."
"She's licking your ass?"
"Yeah! ..her tongue is so wet... oh, isn't that dirty?"
"I'm sure you're clean enough, but you're right, it is kinky! Does it feel good?"
Julie paused and considered, then smiled. "Oh yeah...." she moaned, pressed herself down to get my cock all the way inside her, and we stayed like that for a minute while Beth was busy with her ass. I heard Beth and Mark talking, and I felt a finger enter Julie's ass, the pressure changing on my cock in her pussy. Apparently Beth was teaching Mark how to finger his sister's ass gently, and lick it as well. Beth moved aside, and I heard her and Mark shift their attention to Beth's asshole. I rolled Julie over to fuck her from above. Beth was on all fours next to us, and I saw her hand moved between our legs, and felt a finger, or perhaps two, slide into Julie's ass. Julie's pussy felt even tighter around me, and I cried out as I came, filling Julie's pussy.
When I came to my senses, I realized that Julie and Mark had all their attention on Beth's asshole, and she was just explaining to them about anal sex. Both kids took turns prodding their mother's ass with two fingers, then Julie held Mark's cock in position, watching it sink slowly into Beth's ass.
I sat next to Julie, holding her, watching in fascinating.
"She's really got it in there. She's doing it!" said Julie.
"Yes, I fuck her ass sometimes." I told her. "Your mother is fantastic, she hardly needs to be warmed up. She never ceases to amaze me." I looked down at Julie. "You've got a pussy full of cum. Why don't you let her drink it? That would be nice and kinky for her."
"Oh, yeah." said Julie, and moved over to spread her legs in front of her mom's face.
Beth got busy slurping, and Mark sped up his thrusts into her ass. I sat beside them, watching my wife, who only a few weeks ago would avoid giving me head, lost in a world of lust. She has one of her children with his cock slamming her ass, and the other oozing my cum into her mouth. I grabbed a nipple and twisted it. Mark had his hangs on Beth's hips, pulling her onto him, and Julie had her hands on the back of Beth's head, pulling her mom's face hard onto her clit. I looked a each of my children and we all shared a big grin. Beth was really making her family feel good, getting them off, and she herself was moaning like crazy.
I was getting hard again. I walked off into our bedroom, and came back with one of Beth's larger dildos just a Mark was coming hard in Beth's ass.
"Alright Mark!" I said. "Way to go. Her ass is awesome, isn't it?"
He just nodded, pulling out and sitting back, his mind blown. I held the big dildo up to Beth's pussy and pushed it in, Beth's pussy completely wet but still needing a little time to adjust to the big invader. Julie was squirming around under Beth's mouth, apparently close to orgasm. I held my cock up to Beth's ass and pressed firmly, watching it sink slowly into the now incredibly tight hole.
"Wow." said Mark. "She can take two in her?"
"Oh yes." I said, my cock now all the way inside. "I know she'd love it if we both fuck her sometime, in her pussy and ass. Would you do that for her?"
"Would I? Is that a rhetorical question?" said Mark grinning.
I concentrated on the extreme pleasure of Beth's tightened ass, Beth concentrated on making Julie come. When Julie did, it pushed me over the edge, an incredible feeling as my balls spasmed, but Beth's ass was actually so tight that my come couldn't shoot into her! The pressure was delicious, drawing out the orgasm, the cum finally pressing its way deep up Beth's ass.
We all relaxed. Julie kissed all of us then went off to shower with Mark. Beth and I showered and talked about the incredible sex and our children's acceptance and pleasure with it. She admitted that she had indeed encouraged Julie to join her weight-loss program, in full knowledge of the expected effects, but that Mark was simply acting on his natural horniness.
Looking back, that weekend was the real turning point in our lives. Sex with the kids still didn't feel casual, at least not in the first two weeks, when everything was still so new. Monday morning, instead of getting a hot kiss from my wife when going off to work, I got one from Julie as well. Monday evening Julie came home wanting sex, now, apparently hot and bothered from being at school all day, unable to act on her lust. I gave her a nice long fuck in the living room, then Mark came home and took over. Beth dropped in on us periodically to check on us, as we switched back and forth, trying to sate Julie's lust, her mad desire to get fucked again and again. When I finally couldn't get it up any more, Julie decided that watching her with Beth would get me hard again. She called her mom into the room and the two of them made out, intensely, kissing while grinding their pussies together, fingering each other, until Beth had an orgasm and I was hard as a rock. Then it was back to fucking Julie again... I went to sleep exhausted that night!
Tuesday, when Julie came home, Beth said she had more to teach us and invited us to take a shower with her. We peeled off Julie's tight-fitting clothes, stuck to her body with sweat, and brought her into the shower, between us. After a lot of splashing, kissing and washing each other, Beth brought up the subject of anal stimulation. She showed Julie how to wash the inside of her asshole nice and clean. Julie and I fingered Beth's ass together with soapy fingers, then we turned our attention to Julie, helping her to get used to the feeling of a slippery finger in her ass. We got out of the shower, dried off, got on the bed, and Beth brought up the lube. We taught Julie how to finger Beth's ass for pleasure, then we fingered Julie's ass together while licking her clit, the we took turns kissing and licking her asshole. We managed to give her a nice orgasm with my tongue on her clit and Beth's tongue up her ass. In her post-orgasmic glow, she put up no resistance to the idea of tonguing Beth's ass. I had to put my erection somewhere, so I slid it down Beth's throat while she got her ass got a delicious workout from Julie's tongue. Mark walked in on us, and Julie begged him to fuck her, he just "dropped trou" and got busy in his sister's tight pussy. After I came in Beth's mouth and Beth had an orgasm from Julie's fingers and tongue, we disengaged and Beth proposed that Julie consider getting fucked in the ass.
Julie was game, Mark was definitely up for it, so we got out more lube and the three of us really gave Julie's asshole a workout with our fingers. Finally she said she was ready, and Beth guided Mark's cock into her ass slowly. I remember he didn't last more than two strokes before coming! Julie was disappointed, but we got Mark hard again and this time he lasted a longer time, both of them really getting into it, moaning like crazy. Beth and I fucked, while watching our children ass-fucking their little hearts out. Julie almost had an orgasm of her own that time! When Mark came, I switch from Beth's pussy to her ass, and we both filled the assholes we were fucking with our cum.
The next few days were normal sex - if you can consider your children openly fucking you and each other around the house normal. I didn't get into Julie's ass until the next weekend, on Saturday morning. Julie had been 69ing with Beth, Mark had just finished fucking Julie's ass (coming too quickly). Julie reached back to finger her own ass, moaned something into Beth's pussy that sounded like "I want my Daddy." I got behind her, slipping a finger into her ass alongside her own. She raised up in order to reach back and grab ahold of my cock, bring the tip of it to her own ass. We made intense eye contact as I pushed forward, slowly, watching her beautiful face for signs of pain as I slid in slowly. She winced a few times, but didn't say stop until my large cock was all the way inside, buried deep up her ass. It turned into an incredibly slow, tight, delicious assfuck, Beth's mouth keeping busy on Julie's clit to help her relax, while I slowly worked myself in and out. After I came, Julie said she was sore for the next couple days, only regular sex with her for the rest of that weekend!
