I’m a male, 36 years old. I was adopted as a baby. I met my biological family about 8 years ago. It took several years before i started to get close to them, my half sister especially. This story happened about 2 years ago.

I never intended or ever thought of sleeping with my half sister, it just happened. I was visiting some friends in a city about 3 hours from me. My half sister also lived near there so I figured I’d see her too at some point.

I was out to dinner with my friends when my sister asked if I wanted to meet her downtown at the bars later. She was attending a rock concert and then her and her friends were going out later. I didn’t have anything planned other than dinner that night with my friends so I said sure.

I took an Uber later and met her at one of the bars. She had been drinking a little as had I. She likes loud packed bars, not really my cup of tea. I prefer dive bars off the beaten path. But, I hadn’t seen her for awhile and always enjoyed hanging out with her. We stayed out for a few hours and then some of her friends started to catch Ubers home. Eventually it was just her and I. The night was still fairly young so I asked if we could go to a dive bar I knew about down the block that was a lot quieter. She agreed

We found a small table and got some drinks. We got to talking about lots of different things while we continued to get drink after drink. At one point, she asked me about my marriage. She knew it was not going well. We had talked in the past about how it had turned into a sexless marriage and I’ve been getting frustrated trying to fix it. She said, “Well, I know how you feel, I haven’t had a boyfriend or even been with anyone for over a year”. We both laughed and joked how we share the same DNA which means we have high sex drives. It’s come up before.

At this point, we are both feeling good with liquid courage. She asked where I was staying and I said I had a hotel the next couple days. She lives in a smaller town about 30 minutes away. She was going to take an Uber home. That would have been an expensive Uber ride. I offered for her to just crash at my hotel and she agreed. I told her I’d give her a ride in the morning.

I had no intentions at this point or even thought about her sexually. I was just being a big brother and looking out for her. She was about 6 years younger than me.

We stopped at a gas station on the way to the hotel to get some beer and snacks. We were starving and had the drunk munchies.

In the midst of me trying to be a good brother, I forgot I only had a 1 king bed room. We walked into the room and I was like, “whoops, forgot I had 1 bed”. I told her I’d sleep on the floor. She said, “no, you don’t need to do that, it’s a king bed, it’s fine”.

We continued talking and having some drinks. We then started talking about our sexless lives. It was actually starting to make me horny. I thought I could just jerk off in the bathroom later when she falls asleep. I need to cum to sleep better. It was getting late and I changed into something more comfortable for bed. I offered her some basketball shorts if she wanted. She declined and asked if I would be creeped out if she slept in her underwear and one of my tshirts. I said good for it. She went into the bathroom and I hopped in bed.

I turned off the light and turned the tv on. She walked out of the bathroom. She is not a skinny girl, she has a little extra with a really pretty face. She has huge tits, like DD or something. I could tell she took her bra off. I could see her nipples pointing out of my shirt. The shirt went just passed her underwear but her ass was most definitely not fully covered. I was still horny from earlier, but seeing her got me hard. I could tell I had some pre cum going on. She hopped in bed.

She asked if I was tired, I said not really. I gave her the remote and said pick something. She turned it A&E. Of course the first 48 was marathoning.

We started talking again. At one point she asked, “Before you found us, did you ever wonder or fear accidentally sleeping with me or our mom?”. I actually did. I like older women too so my mom could have been a possibility. We laughed about it. My intrusive thoughts started to take over. I started to get the feeling she may be horny too. I didn’t want to make a move and be wrong, especially if it ruined our relationship. I kept thinking how can I know if she wants to hookup.

We were on our sides facing each other. Still talking about our miserable love lives. She asked if I was going to cheat on my wife to fill that void. I told her it crosses my mind every day. I was certain at this point that she wanted me. Between her asking where I was staying, our sex lives talks, her in my bed half naked….she’s gotta be thinking the same. I was gonna make a move or say something.

She asked if I had a phone charger. I said it’s behind you on the bedside table. She rolled over to plug her phone in. She is a lot shorter than me. She was closer to the middle of the bed so she really had to reach over. When she rolled over the shirt pulled up and the sheets lowered enough. I could see her ass through her see thru underwear. This was my chance. I blurted out “Nice Ass!”. Cringe I know.

She laughed but didn’t even try to cover up. As she finished plugging the phone in she said, “Do you like it?” While giving it a wiggle. I told her it was perfect. She gave a soft laugh and rolled back over to face me.

At this point my dick was wet and hard. I was committed. She asked me if I had ever fantasized about her in anyway. I said, “Not until now”. She laughed. She said she had about me and that she had been trying to drop hints the past year. It started to click, I was just too stupid to see it.

I told her I was horny, hard, and wet. She said she had been horny since the bars. She then ran her hand through my hair and placed it on my cheek. She leaned in and we started to kiss.

I nearly came. I couldn’t believe it was happening. She stopped kissing. She ask, “Are you ok with this? Like it doesn’t freak you out that I’m your sister?”. It did not. I was all for it. We both had the same fucked up sex drives. We agreed nobody could find out.

She started kissing me again. I put my right hand on her waist. She was a good kisser. We started to move our hands all over each other. She moved closer to me and put a leg between my legs. Her thigh was touching my balls. I started to feel her tits. They were so big. I was almost shaking. Everything felt so good.

She sat up and took her shirt off. Her nipples were just bigger than a quarter. They were perfect. She then said lay back. She got on top of me and took my shirt off. She leaned down and put her tits in my face. I started sucking on her nipples. She started to moan. I was doing everything in my power to not cum.

She sat back up, still on top of me. She said, “I’ve been wanting to do this for so long”. “I’m so wet right now”. I reached down and felt her pussy through her panties, she was soaked.

She backed up a little and grabbed my shorts waist line. Her fingers were barely inside my boxers, resting on my pubic hair. It made me shake and sent an intense feeling through My body. She then pulled my pants down just passed my balls. She got down on her belly between my legs. She started to suck my dick. After a few minutes I told her I’m so close to cumming because I’m crazy horny. She stopped and laughed. She said same for her and that she wasn’t going to last long either.

She took my pants the rest of the way off. I was now fully naked. She stood up off the bed and took her panties off and then climbed back on me. I could see her pussy, shaven and nice and perfect. It actually reminded me of my wife's. She grabbed my dick and said, "I'm on birth control, but don't cum in me. I'll tell you when to start fucking me."

She took my dick and started rubbing it on her clit and then slid it in her pussy. It was like losing my virginity all over again. A feeling like nothing I've ever experienced. She just left it in and started to rub her clit. I moved my dick very very slowly up and down so I didn't cum yet. I could tell she was really close to cumming. She wasn't loud, but not quiet either. She was starting to shake a bit in her legs and then she said, "Oh fuck, I'm gonna cum, fuck me now". I started going, she began to orgasm and I could feel myself getting close. I reached up and put a hand on her tit and my other hand on her ass. She started to shake and then moaned hard. She kind of hunched over having almost like stomach spams. It was so hot. She said "Oh fuck that was good, keep going till you cum and pull out and I'll finish you".

It wasn't more than 30 more seconds and I had to cum. I pulled out and she grabbed my dick and continued to jerk it off as I came. It went so high in the air, there was a ton of it. She angled it so he landed on her stomach and under her tits. She moaned while it happened. It was one of the best orgasms I've ever had.

I watched her grab a towel and she cleaned us both up. We couldn't have had sex for me than 5 minutes we were both so horny. She laid back down next to me and put her head on my shoulder. We were both super relieved and happy. We slept naked in bed that night and were very close to each other most the night.

The next morning we both woke up with hangovers. She asked how I felt about last night. I said it was amazing. She agreed. She wanted to watch me cum again because she couldn't believe how much cum I could produce. She thought it was hot. She ended up teasing me for awhile to get me worked up. We ended up mutual masterbating and she watched me cum.

Neither of us have ever regretted it. I think it's easier for us because we never grew up together as kids. She feels more like a close friend than my half sister. We continue to remain close to this day. We have hooked up many other times. I'm divorced now so we see each other a lot more than we used too. No matter what we don't exchange nude photos or anything like that. We also talk via snap a lot so messages dissappear. I'm not sure how long we'll keep hooking up, but I'm enjoying as long as I can.
