Tell us about your PARTNER(S). What did they look like? How well did you know them, had you hooked up before? How/Where did you meet them? How did you feel about them before the hookup? I was adopted and separated from my half siblings when we were very young. Being the oldest, I was 5 years old when adopted. My sister was 4. My brother was 3. After we were adopted, I never saw or heard from them. So naturally, I forgot exactly how they looked. When I was 18 and my sister was 17, we met at a mall, but only hung out through mutual friends. At the time, I didn’t know this was my long lost half-sister and she didn’t know I was her half brother. We began to hang out more just as friends over the next few months. I honestly thought she was hot as fuck. She had long brown hair with blonde streaks, thick, soft double d sized tits, a thick figure, and had a very gothy way of dressing. I’m very much into that kind of thing.

How/where did the hookup BEGIN? What led to it? Was planning involved? Who instigated it? One night, she was at my house and we were browsing MySpace, and we both just happened to turn towards each other after making fun of a couple people we knew and then began kissing. We took it to the bedroom and ripped each other’s clothes off. I would say she probably instigated it because she later told me that she had been thinking of this for a while.

What happened DURING the hookup? What sexual behaviors took place (e.g., oral, vaginal, anal, kinky stuff)? How did you feel during it? How did they behave toward you? Were they a good lover? What did you talk about? How did it end? Immediately, after the initial kissing and feeling all over her body, I made my way down to her pussy and went to town. She was by far the sweetest girl I have ever tasted and by far the easiest to get off. I could feel her spasming with my tongue and lips. After that, she climbed on top of me and rode me good. To this day, I have not felt a tighter pussy at all. She was so loving and you could tell she legitimately wanted this. When I told her I was going to cum, she started grinding me harder and directed me to cum inside her. I fought to pull out, but she forced me to cum inside her. At the time, she gripped my penis with her vaginal muscles and gave me the most Earth shattering orgasm I have ever had. Luckily, she told me she was on the pill afterwards. We went at it 3 more times until I was sore as fuck. I don’t know how she wasn’t.

How sexually satisfying was this hookup? Very

Did you have an orgasm? Yes, more than one

Did your partner have an orgasm? Yes, multiple

What happened AFTER the hookup? How did you feel about it the next day? What are/were your expectations/hopes for the future with this person? How do you feel about them now? It was amazing! We started dating for a while after until I finally met her adopted mother who informed me that she remembered me as a kid and that was my siblings. After checking various sources, it was confirmed… I had been fucking and was in a relationship with my own sister. It was the strangest feeling. Luckily she never told her mom the full nature of our relationship. Even after finding out, we still dated and had sex for a few months afterwards. We never really officially ended it. It just kind of died out because now people knew that we were siblings. Weirdest time of my life, but honestly, the best sex I have ever had.

What was the WORST thing about this hookup? Finding out that she was my half sister. That was depressing to me. I kept thinking, “What are the fucking chances!?”.

All things considered, how POSITIVE was this experience? Fairly positive

All things considered, how NEGATIVE was this experience? A little negative

Anything else you want to add about this hookup? As farfetched as this story is, I honestly miss having that kind of relationship with my sister. I am married to another woman and live a couple states away from her now, so we barely ever communicate.

What are your thoughts on casual sex more generally, the role it has played in your life, and/or its role in society? What would you like to see changed in that regard? It would be wise to play it safe. Condoms, the pill, and anything else you can use to protect yourself. I was pretty stupid early on in life.

What do you think about the Casual Sex Project? Excellent project!
