I was living with 3 straight guys at my last year of college. One of them was a hot guy who liked to work out and run. One day we were talking about why male athletes slap each other’s butts. It became a thing then between the two of us. It was more spontaneous and funny, but of course I found it hot. When it was time to move out, we all said our goodbyes. For him though, when it was just us left, I said I need a slap on the butt before we go. He does it, and I say I’ll miss it, and that I’ll continue thinking about him while jacking off. He laughs and says he’s glad he was able to fuel my imagination. I said, well, seeing you naked and the butt slaps helped. We kept in touch, and I went to his wedding a few years later. He’s a cool guy.
