Not sex. She was a bit shorter than I. We were on the subway in Washington D C. I think she was about 18 or so, it was jam packed, morning rush hour. I was going to Union Station, anyway... I remember how round her breast were she was in a white tee shirt, cotton shorts that hung loose but wher tight on her butt. I thought she was cute, but not a knockout. She kept watching me watch her. Each stop as more people got on we kept moving closer. The rocking of the subway and people pushing me caused my dick to keep bumping her thigh, at the next stop she shifted so that her butt was next to my hard dick. I don't think she ment to do this and we really were not touching, but she smiled at me and I went ape. asthe subway pulled out of the station I bumped up to her butt, the number of people jamming in made it possible. Next thing I know my dick {still in my shorts} is pressed between the cheeks of her firm butt. Every move of the subway caused my dick to rubb her. She looked back at me smiled again then looked off as if nothing was going on. Next thing I know we are at union station. I move to get off the subway, as I walked past her she shifted her body so my dick had to brush past her cheek and thigh. She moved infront of me to an open seat, yet still standing she brushed her legg between mine and lifted her thigh against my hard on. I got off the train looked back at her and she smiled again and said "have a nice day!" I started to cum on myself as the train left Union. Sex can not be better than that moment.
