“Do?” I asked.
Alison shook her head. “You did notice?” She could tell I had no clue. “My dear sweetheart. Didn’t you notice Tracy giving you a show?” I still looked dumbfounded. “Allen, didn’t you notice how she kept leaning so you could she down her top? Didn’t you see how she sat cross legged so you could see her puss?”
“She did that on purpose?” I asked, for I had noticed very well. I had noticed Tracy had very shapely breasts and a nice pussy. “On purpose?”
Of course I had spied, or tried to, on my sister just like most brothers. I had noticed when she got tits. I had noticed when she turned into a woman from a girl. I had even jacked off thinking about her though I would never admit that to anyone. But was Tracy putting on a show for me?
“A girl never does that by accident. She wanted you to see,” Alison said. “What are you going to do?”
“Nothing,” I said logically, at least it seemed logical to me.
Alison smiled indulgently, “We’ll see.” She sat up and looked at me seriously. “Allen, don’t hurt Tracy’s feelings. And don’t get all guilty. Promise me that whatever happens you’ll tell me.”
That was easy since I had no idea what Alison was so serious about. “Sure. Now what the heck are you talking about?”
She patted my hand. “I told you I read about this stuff, the psychology of sex. It happens a lot so there’s nothing to feel guilty about.”
Girls, I said to myself.
Little did I know at the time that Alison knew exactly what she was talking about. I just wish she had told me so I’d have known what to expect. I guess guys are supposed to be kept in the dark.
It started a few nights later. As a note that maybe helps, our house had an unusual layout. My parent’s room was all the way on the other side of the house. On ‘our’ side, Tracy and I had our rooms, a bath we shared, and the den. As long as there wasn’t blood curdling screams coming from our side, we basically had it to ourselves. I came out of my room to see Tracy coming out of the bath after her shower. Nothing unusual about that except she was buck naked. She normally would be wrapped in a long towel. I stopped dead and stared.
Tracy stopped but didn’t try to cover up. “Don’t stare,” she said. “You and Alison were naked.”
“Yeah, and you stared,” I said.
“Did not.” She said. I looked up to look in her eyes. She puffed up for a second, then smiled. “Okay, I stared.”
“Okay, don’t blame me for staring,” I said looking at her. It was completely strange, my little sister standing naked and seemingly unconcerned. In fact, there was a bit of the tease in her eyes. She wasn’t such a little sister anymore. Maybe she was only fourteen but damn she looked hot. She was standing with one leg bent and I realized it was the classic pose used to make a woman enticing since time began, and it did. “God, Tracy, you look beautiful.”
“Really?” she asked.
I nodded.
“Take off your clothes,” she said.
“Tracy!”
“Don’t be a poop. No one ever comes to our side. Come on, Allen. I’m naked. Take off your clothes,” she begged.
I looked down the hall and realized she was right, but… I ducked back into my room with Tracy following. It was really weird to be taking off my shirt and jeans in front of her. Of course, I had an amazing erection from seeing her naked. As I stood up from slipping off my jeans it bounced up and stood straight. Tracy stared at it just as she had before.
“What is it like when Alison, you know, sucks on it?” she asked.
I smiled, “It’s great.”
Tracy knelt in front of me and I wondered what she was doing. Naïve me! She took my cock and put the tip in her mouth and started sucking and licking. I was stunned. Tracy? Then like a ton of bricks it hit me, everything Alison had been saying. She somehow knew Tracy was going to do this. How? But I really didn’t have time for deep thoughts as Tracy continued sucking my cock. The other thought that struck me like a two by four was, Alison knew and she hadn’t said not to.
Tracy looked up right about then and asked, “Have you ever done this to a girl?”
“No, but I know what to do,” I said. After all, I had read stories about eating pussy.
Tracy stood up. I lay down on my bed and she crawled over me straddling my head with her knees. I felt her take my cock back into her mouth. Funny, I had been having sex for months but I was now looking up at my very first pussy, all pink and wet. She was just out of the shower and she smelled faintly of soap.
The stories really didn’t help all that much now that I was looking at a real live pussy. I spread her labia but still didn’t really know what to do. I stuck out my tongue and started licking. I must have done something right because pretty soon, Tracy’s hips were bouncing around and she was grinding her pussy down on my face. It was sort of claustrophobic, that first time.
We had been 69ing for a while, when Tracy rolled off. “Allen, please do me.”
She lay back on the bed, her legs spread wide, her pussy wet and pink. I would have fucked anything right then I was so horny. I moved over her and realized this was very different. I had always been able to see where I sticking my dick when I was fucking Alison in the positions we used. Now, I was going only by feel and didn’t have a clue. “Help me, Tracy,” I said.
She reached between us and led my cock to her. I felt the heat of her pussy. As I did with Alison, I slowly entered allowing Tracy to get used to me. The difference showed up when as I pushed suddenly, her cherry ripped.
“Ow,” Tracy yipped.
“You okay?” I asked.
She took a second to assess the damage. “Yeah, it’s fine. God, Allen, you feel so big.”
I was hardly inside and she thought she was full. I slowly kept sliding deeper and deeper as Tracy moaned, I think in pleasure, until I was all the way inside. It was incredible. It was very much like fucking Alison but also different in subtle but wonderful ways. The thought flashed through my mind that I get to do both, what a lucky guy.
I rolled my hips grinding against Tracy causing her to gasp, “Yessss…” I fucked her slow and deep at first then faster as she started moving her hips in time with mine. We built up a good head of steam and soon the rumbling began in my balls. “Tracy, I’m going to cum,” I moaned.
“Oh God. Allen, give it to me,” Tracy shouted.
I did. Pumping furiously, I blasted my cum into her pulsing pussy. Again and again, loads of cum spattered from my cock and into my sister below me. Drained, I fell to her side. She snuggled into me.
“Thank you, Allen,” she said.
“It was my pleasure, Tracy,” I said.
She giggled at that. “God, we actually did it.”
“I know.” It was strange now that the excitement was wearing off. Shit, I had fucked my sister. I had convinced myself that Alison was going to think it was okay, but what if she didn’t? What would Mom or Dad say? Oh my God, they’d skin me alive. “Tracy, we can’t tell anyone,” I said starting to worry.
“Well, duh. Like I’m going to go tell everyone I seduced my brother?”
“Oh yeah,” I said.
“Don’t worry, bro. No one is going to know except me and you. Thank you for making my first time good,” she said.
*****
That did make me feel a little less nervous but I still was worried about Alison. I told her the next day at school. We had lunch away from everyone else so we could talk as we often did so we could talk dirty. She could tell I had something on my mind and finally tired of hinting came out and told me, out with it!
“Tracy came in my room last night, and she was naked, and…” I stopped
“And?” Alison asked.
“She got in bed with me and… we had sex,” I said in a rush. I looked at Alison and saw her getting angry. I had screwed up and before I could even say anything the tears started.
Alison saw the tears and said, “Wait, don’t cry you dufus. I was just pretending to be mad. I was going to tease you,” she said.
“Tease me?” I asked holding back the tears.
“Yes, tease you. Allen, I practically told you it was okay, didn’t I? I knew Tracy was going to do something like this and I didn’t tell you not too. In fact, I told you not to feel guilty, that it happens a lot.”
I nodded feeling a lot better.
“Okay, tell me what happened. I want all the salacious details,” she said.
“Alison,” I said shocked.
“If I only get to enjoy this vicariously, you need to make it a good story,” she said.
I could see she was serious. I started in and her encouragement got me going. I could have sent it to Penthouse by the time I was done.
Because of her unique situation, Alison was very sensitive and knowledgeable about sexual preferences and differences. She read all sorts of papers and kept up on websites. She also had kept up a conversation with a couple counselors who had worked with her when she was confronting her own gender issues. One of the things the counselor had told her was how frequent incest is, both in fantasies and in reality. Let’s face it, right at the point when all these feeling start boiling up at puberty, who are the people of the opposite gender you care for and trust? Family, of course. And who is there, able to take advantage of the opportunity when it arises, so to speak, family of course.
Alison hadn’t been shocked when she realized Tracy was attracted to me. In fact, she admitted she had been curious and a little bit turned on herself since Tracy was a genetic girl. Alison admitted to me that she had fantasies about me and Tracy, fantasies that included her. I of course immediately started seeing a threesome, but Alison said no, she didn’t want Tracy to feel like she had to, in Alison’s words, be with a freak. This was something that has always bothered me. Alison sort of tried to joke about her status, but I can feel the truth right under the surface when she makes jokes like that, calling herself a freak, and then laughing. I know it hurts and there is nothing I can do other than love her for what she is.
So Alison allowed, maybe even encouraged me to share myself with Tracy. I had Alison and Tracy. It wasn’t all that unusual for me to get a bj from Alison after school while we supposedly doing homework and have Tracy sneak over at bedtime and have a quick roll in the hay. Lucky for me I was sixteen and able to get erections at the drop of a hat, and Alison and Tracy had lots of hats.
It was a Saturday night and my folks had an evening out planned so Alison and I had planned an evening in, fucking like rabbits. We were just getting started, our clothes on the floor and us in the bed when Tracy knocked and came in. Tracy stood there in the door staring.
Alison as always kept her head. “Come on in.”
Alison was behind me and moved to hide her equipment. Tracy came to the bed and sat on the edge. “Alison, you don’t need to hide. I have seen it once… Well, I peeked a few times too. I didn’t understand it at first but I started reading stuff.”
Alison, because of her unique background, is very sensitive to others and reads people very well. “So, do you mind that Allen and I are a couple?”
“I guess I’m a little jealous, but I know I can’t really be his girlfriend. And you are so cool to share him with me I really like you for being so cool,” Tracy said. “So, thanks. That’s funny, me thanking you for it.”
Alison smiled, “No, it’s cool that you thanked me.”
“You ever use that?” Tracy asked Alison. Alison had relaxed enough that Tracy could see her equipment.
“No, it isn’t really part of me,” Alison explained.
“Yes it is,” Tracy said laughing. “I mean, I like looking at it. Does it get hard?”
I nodded. Tracy asked, “Can I see?” Alison looked surprised and a bit leery but nodded. Tracy came around to Alison’s side of the bed. Alison laid back, a look of concern clouding her face. I could tell she still felt awkward about her condition. Tracy looked unconcerned as she took Alison’s small dick and started playing with it. Alison closed her eyes. Tracy winked at me and lowered her head sucking Alison’s dick into her mouth.
Alison’s eyes sprang open as she felt Tracy’s lips, “Oh God.”
Tracy sort of smiled, as much as a girl can with a dick between her lips and started sucking. Alison’s head fell back onto the bed and I could see the pleasure building. I was a little surprised how much she was enjoying the bj. I guess thinking of her as a girl as I did, I just never realized. Her dick got hard as Tracy sucked it. It never got that big but it was respectable. That’s when Tracy really surprised me. She was wearing her nightgown when she sat up, whipped it over her head, squatted over Alison and sat on her dick, moaning as she filled herself with my girlfriend’s erection. It happened so fast I don’t think Alison or I realized what was happening. My sister was now fucking herself on my girlfriend.
My cock sprang up with dangerous pressure. It was so hot watching my girlfriend and sister fucking. Tracy was bobbing up and down on Alison’s dick. Alison was moaning and Tracy joined her in a unison of lust. Tracy was really grinding now, rubbing her clitoris all over Alison’s loins. Suddenly, Tracy went stiff as a board, threw her head back, and cried out. Alison’s eyes flew open as Tracy’s pussy starting pulsing on her dick. Alison joined Tracy in climax cumming along with my sister. The two girls filled the air with their climax. I have never heard anything so sexy in my life as those two together.
As Alison slumped back onto the bed, Tracy slumped against her, titties pressed against titties. I sat there with my cock red and hard, pulsing with desire and need. I needed to fuck somebody. Tracy fell off to the side and Alison rolled towards her displaying her fine ass to me. I grabbed the lube, lay behind my darling and slathered the lube on my cock. I pressed forward, sliding between her half globes and found her tight opening. Alison felt the head against her puckered ass and moaned. She looked back and saw my need. Smiling, she pressed back and the head of my cock popped into her.
I held still for a moment to let her get used to the pressure. Once she pressed back again, I started fucking Alison. Tracy had recovered enough to realize what was happening. She leaned over the prostrate form of Alison and looked. “Alison, does that hurt?”
“God no. It feels so good. Allen, fuck me,” she moaned.
Tracy stared, fixated by my cock sliding deeply into Alison’s tight ass. I was so wound up from watching them that I couldn’t hold back. The rumbling began and I felt the cum deep in my balls, then exploding up the shaft and into Alison.
“Cumming,” I cried out as again and again I buried my staff in her backside and sent another streamer of cum into her. There were three moans filling the air as I blasted my last drop into her.
I was lying in the middle of the bed with one girl on each side. We talked quietly as we recovered from the wild sex. Tracy was asking Alison about anal sex and Alison told her the technical details and also the pleasures.
Tracy rolled over so she was draped across my chest but talking to Alison. “I’d like to try anal sex,” she said.
Alison said, “Allen is gentle.”
Tracy interrupted her, “No. He’s kind of big.” Tracy looked down at my darling girlfriend’s little dickie. “I want to try with yours.”
Alison looked surprised. “But Tracy, I’m a girl.”
Tracy smiled her little wicked smile, one I would come to know well, the one that meant she was on the prowl for wicked sex and wasn’t going to be put off. “Alison, we already fucked. Come on, fuck me that way. I’ll promise not to tell anyone you’re a dyke.”
It was so ridiculous. Alison and I stared at Tracy for several seconds, then she started giggling and I followed. In seconds all of us were rolling on the bed laughing like fools. For it was ridiculous for any of us to be constrained by gender. What mattered was how we felt about each other. What also mattered was that we cared for each other. What really mattered was making each other happy.
When we settled down, Alison got serious. “All right, Tracy. If you want me too…”
Tracy nodded. Now she looked a little nervous. “If it hurts, you’ll stop.”
Alison smiled, “It won’t hurt. I think you’ll love it.”
Tracy smiled, then climbed across me. She leaned down and kissed Alison. Soon, their kissing was passionate, with hands roaming over each others bodies, tweaking nipples, rubbing breasts, grinding loins together. Once she was hard, Alison had Tracy roll over and lifted her butt in the air. She grabbed the tube and slathered it in Tracy’s rear. Slowly, she used one finger to gently work the lube in. Then she ran her finger around the rim, relaxing her butt. Tracy was moaning at the sensations. Alison worked a second finger in and repeated the massage until Tracy’s sphincter was relaxed.
Alison lined up behind Tracy and slowly inserted her girl cock in her butt. Tracy moaned in pleasure. Alison began slowly fucking my sister in the rear. I was getting really turned on so I rolled close and began touching Tracy in all of her secret spots. She rolled her head to me and it was a mask of lust. I kissed her and she thrust her tongue in, raping my mouth. I responded, catching the heat of passion from her. I could feel Alison pushing hard into Tracy as we kissed, until Tracy pulled away so she could scream in climax. I looked up to see Alison throw her head back as she pumped her girl cum into Tracy’s ass. They both crumpled to the bed, used up.
That was pretty typical when the three of us got together for sex. You’d think as the guy I’d be the one pushing for new and different experiences. I never had the chance since Tracy and Alison were always inventive. I had trouble keeping up with them. Let your mind go with possibilities and we probably tried it.
That’s how I spent my junior and senior years: fucking my girlfriend and sister. Talk about the perfect life for a high school guy. When Alison couldn’t take care of my needs, Tracy was available in the evenings. All I had to do was quietly invite her to share the shower. She’d get this lustful grin and we’d be off. And the threesomes added variety and always kept our sex lives fresh. It turned out that both Alison and Tracy had a bit of voyeur in them and liked it when I’d describe my last time alone with the other. Either they would want to try the same thing, or they’d get turned on like crazy and I’d have to screw them until I couldn’t go anymore, or even better, they’d try to outdo the other girl. Those were the best times. Funny, but I remember my folks commenting on how well Tracy and I got along. If they only knew…
Alison had her surgery right after graduation and was mostly recovered by Fall. It was a new experimental surgery. They took her genome; cut out the Y and doubled the X. Then using stem cells they encouraged a new set of genitals to grow in the lab. So instead of surgery to fake a set of almost female parts, they lopped off the male and put in new lab grown and matured parts, genetically her female parts. The technically most advanced element was the nerves. But they used stem cells to ‘weld’ the new nerves to her nerves and the stem cells grew to become nerve cells reconnecting the new and the old.
So Alison wound up with a new set of female genitals just as if she had been born with them. If it wasn’t for the scars no one would even know. You have to be real close between her legs to see them so only a few people besides her doctor have any idea. The biggest deal was she now had functioning ovaries and could have kids, once all the muscles healed. Alison might be one of the few women who actually enjoy their periods since it reminds her she is a real woman now. The docs said give it a couple years before she got pregnant. Once she was healed and the muscles knitted, they gave the okay for sex. One funny thing is her new genitals had a hymen so I got to take her virginity twice. The first time I got to eat her pussy to orgasm was so incredible we both cried with happiness.
We went to college entering as juniors. She majored in Psych and I in engineering. We married two years later and I got a job in Seattle. She finished a counseling degree at UW and set up shop. We had two kids, a boy and a girl. The boy takes after Alison, blue eyes and blonde hair, and the girl takes after me in color but Alison in beauty. We didn’t want them to grow up believing they had to be one kind or the other and tried to avoid gender typing them, so of course they are completely gender typed. Like parents who think they can keep boys from guns, nature has a big surprise. Our son is the typical roughhousing boy, picking up sticks to be guns from the time he was three. The girl is all about dolls, and having tea and frilly dresses. She was a princess from the time she was three. Their gender fits them like a glove.
When Tracy comes to visit she still climbs in bed with us, although she complains that she liked it better when there were two cocks to please her. I like it better now that I have two women devoted to my pleasure. And it is all because I was open minded with Alison and Tracy. It makes me wonder how much people miss out because they have already made up their minds.
Warning to those who don’t realize this is all fantasy – Kids, don’t try this at home. Don’t have sex with your brother or sister, unless they are really hot. Uncles and aunts are okay as long as you are the one who asks them first. Cousins are legal almost everywhere. Do use condoms, even with your siblings, because you don’t really know who they have been fucking. Maybe your brother has been fucking that slutty bitch at school, the one who is like a Vespa: fun to ride but you don’t want your friends to see you on it.
Guys, sorry if I creeped you out with this one. Just figure it is a chick story, love and all that crap, and forget you ever read it...
