By request, here is a story of a time when I got naked and had sex in a parking garage.
I met up with one of my regular fuck buddies at a parking garage because we were SUPPOSED to go to a party. Him and his buddies were at a movie, that I didn't care to go to, but were going to a party afterwards, and invited me. However, when I got there, it became clear they had other ideas in mind, and the party never really left the parking garage. It was him and about 4 or 5 of his friends in a garage after they had went to some movie.
