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? Some context: I broke up with my ex girlfriend over a decade ago. I hadn’t seen her or anyone in her family since that time, despite living in the same general area. Fast forward to now. I’ve been trying to get back into shape after having a surgery. I’m by no means overweight, but I hate the feeling of being sluggish. Anyway, the local rec center had a great gym with personal trainers for hire. Since I do better in the gym with someone there to push me, I paid for a few months. On my introductory visit, they introduced me to one of the trainers. As soon as she turned around, I recognized her. It was my ex’s little sister. She had definitely grown up (she was 15 when I broke up with her sister)! Obviously, she was in good shape being a personal trainer, but she was also very attractive, much more so than her sister.

How/where did the hookup BEGIN? What led to it? Was planning involved? Who instigated it? The first training session was a bit awkward, but we started talking more and more (thankfully not about her sister) and started to hit it off. On the fourth session, she caught me looking at her ass. I thought I was toast! Instead, she proceeded to tell me how she had a crush on me when I was dating her sister and asked if I’d like to get dinner after her shift. After a nice dinner at the local Italian restaurant, we chatted a bit in the parking lot. I was about to leave for the night when she said, “Wait!” I turn around and she proceeded to kiss me and then she asked: “Want to come to my place?”

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? We walked into her apartment and immediately picked up where we left off. Soon, I slid a hand between her jeans and belly and started to rub her pussy through her panties. Not long after, she unbuttoned my pants and slid them and my boxer briefs down to my ankles. I soon felt the warmth of her lips and tongue as they wrapped around my cock. Partly because she was so damn good at it, and partly because of who it was, I felt close to coming. “I’m going to come!” She went faster as I came in her mouth. Wanting to make sure I repaid the favor, I immediately took off her jeans and panties and started to go down on her. It didn’t take long for her to come either. I have to say that, like her sister, she was very orgasmic with oral. We rested a few minutes and chatted more about what she has been doing over the last few years. That led to more oral and me telling her that I wanted to be inside her. She shook her head, laid on her back, and guided my cock into her pussy. We switched positions several times before I realized we had forgotten a condom. She told me she didn’t care because she was on the pill (I had a vasectomy anyway, but was always conscious of STDs). I then felt myself about to come and told her as such. She grabbed my ass and pulled me in tight. After a few more thrusts, she was filled with my cum.

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? Over the last week, we’ve hooked up after every workout. She hasn’t told her family yet and I hope she keeps it that way. The strange thing is, I actually feel a connection to her. She’s not nutty like her sister and is actually fun to be with.

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? Casual sex should be the norm. We as humans are in denial about what we really are: sexual animals.
