My sister and I had a very sheltered upbringing. We were 2 white, "Christian raised" kids living in a pretty bad neighborhood. When we weren't at school, we spent pretty much all of our time inside the house. Weren't really even allowed to go outside. I don't blame my parents for that stance. Looking back, it probably was the right choice to make. But at the time, we hated them for it.

I'm Nick. I'm 33. now. My sister is Tracy. She's 31. I'm pretty good looking, lol, if I may so say. Decent body. About 6'3" tall. Tracy looks great. Always has. She developed at age early age. Even if I had tried, I couldn't have ignored it. She's about 5'8". Growing up, we did everything together. We really had no other choice. Even as teens, we were never allowed to date or really go anywhere with friends. We'd just hang out and watch tv, or play whatever game we'd come up with.

I can remember like it was yesterday, when we used to watch Saved by the Bell on tv. It was probably our favorite show. For some reason one day, we decided that we were going to "play" Saved by the Bell. I'd be Zack Morris, and she'd be Kelly Kapowski. Innocent enough, at least until we decided we'd try kissing like we were them. I can't remember why we decided why that was a good idea, but from our first kiss, we were hooked. We used to make out and feel each other up in my bedroom while my dad was at work and my mom was in the living room or kitchen. We almost got caught a countless number of times.

I think it was maybe 2 years after we started doing that, that we became much more sexual curious. I can remember telling her I'd really like to try having her give me a blowjob, and in return I'd go down on her. I think the first time she blew me, I must have lasted about 30 seconds before I came in her mouth and she spit it out, lol. I think that was probably the only time in all of our years doing it that she didn't swallow. I didn't waste any time returning the favor. I remember her whole body shaking when she had her first orgasm. After that, we'd frequently do oral with each other, or hand job and fingering action. Even with that, I still used to jerk off a ton, thinking about her, or some girl from school.

I think we only lasted about 4 months in that set up before we started to talk about doing more. We both wanted to fuck. We were horny teenagers with no other outlet. I had no hesitation. I wanted to jump
right in. She was a bit hesitant. Well, she was just worried. "What if I get pregnant?" was pretty much her standard response. "Don't worry, I'll pull out. I promise." "Yeah, but what if you have an accident and don't pull out in time? We'd be screwed." We must have had that conversation between 15-20 times.

One day when we began our usual making out and groping, I guess I just decided I had had enough. It was going to happen today. My parents were gone. At church, of all places. We lucked out and didn't have to go for once. Looking at that body, and that pretty face... I just had to have it. We kissed. I was a bit more aggressive than usual. She noticed, and liked it. I took off her shirt, which was actually a rarity. We'd always keep most of our clothes on, in fear of getting caught. But with them gone...

This was it. I took off her bra. I think I stopped and stared at/played with her tits for a good 5 minutes, lol. I took off my shirt and we resumed kissing for a bit, and then I took off her pants and laid her on her bed. I slid off her panties, and started to lick her pussy. She was loud. It was nice to have the freedom to do that for once, and she took advantage. I couldn't take it any more. I got up and got naked. She laid and stared at me, and my cock, which was rock hard. I was pretty much fully grown by that point. My cock's a little over 7 inches long. Anyway, she started to sit up and move towards the end of the bed, where she'd normally sit and blow me. "Not today" I told her. I pushed her onto her back. She lay still and gasped. I crawled onto the bed and kissed her. Hard. I asked her if she was ready, and she hesitated. "Yeah. Um no. I don't know. I want to but... Yeah."

I got myself over her and shoved her legs open, and moved myself in between them. I looked up and down at her gorgeous body. I moved in closer, positioned the tip of my cock on the opening of her pussy, and I shoved it in. She screamed, and tears filled her eyes. I loved it. I may have only been a teenager, but she was my little sister, and it was not lost on me that I was popping her cherry. It felt like heaven inside her. I was afraid to move at first, worried that I'd blow my load right then and there.

Her hips squirmed as I just kept pushing in, trying to shove in as much of my cock as I could. She looked me dead in the eyes and said "promise?" I nodded, yes. I started to fuck her, slowly. In my mind, I just wanted to fuck her hard and fast. But instead, I went slow, stopping after every thrust to avoid cumming. Even with that, I didn't last long. I pulled out, and jerked myself off as I shot my load on her stomach. She smiled but still had tears in her eyes. I smiled and leaned in and kissed her. I went and cleaned my cock off with some toilet paper, and went back into her room to find her still laying there. Neither of us spoke. I was somewhat afraid to ask anything. Instead, I just worried about me. I got back onto the bed and I pushed her legs back open. To this day, I still don't know if she wanted to do it again or not. We don't really talk about our first time. But I wanted it. I slowly put my cock inside her again, and began to fuck her. I started slow again, taking time to kiss her as I'd thrust. I told her "I love you" and she said "I love you too, Nick." Eventually, my desire got the best of me. I started to fuck her, hard and fast. She screamed and whined as I did my best to shove every inch of my cock into her tiny pussy. I lasted much longer this time, but still nothing compared to my stamina these days. I was going to cum. I wanted to cum inside her so badly. I can admit now that I was probably about 90% of the way towards deciding to shoot inside her. But at the last second, I pulled out. Shot on her stomach again. By this point, we were out of time. We needed to clean up and get dressed before mom and dad got home. We rushed, barely saying a word to each other. She went to take a shower and I went to my room and just went to bed early. We still don't really talk about that first time.

We've been having sex together ever since. She's had boyfriends and I've had girlfriends, and we've had sex with other people, but nothing ever lasts. We keep ending up back with each other. At first, we just relied on me pulling out. Eventually she managed to find a way to consistently get condoms from a friend at school. So we switched to using condoms. My parents found an unopened condom once and flipped out.

When I went off to college, she'd come visit me. We both went through a tough period where we were pretty depressed. We hadn't been that far apart before. It was on a drunken night when I finally caved. I fucked her in my dorm room, without a condom and shot inside her. It was a very intense moment, as we had both been waiting and wanting that for years. Neither of us cared that my roommates were out in the living room area, undoubtedly hearing what was happening.

I got her pregnant twice while I was in college. She had a miscarriage both times. I never finished college.

Eventually, we ended up moving to another state, far away from anyone who knows us. She changed her last name. We've been living together as a couple for several years now. We've got one daughter who is, miraculously, healthy as can be. Every other pregnancy has resulted in a miscarriage. It's been going on so long that most of the time it doesn't even feel like we're related. But every once in a while, I like to remind myself that it's still my little sister that I've been fucking all this time.
