I was busting for a piss on the way home one night and went to some dingy public toilets, I was a bit pissed and soon as I walked in the smell of dirty toilets and damp filled my senses, it was pitch black but I could make out shadows, I wasnt looking for anybody just wanted a slash, I got my cock out had a piss and was just doing my fles up when a man grabbed me and stuck his tongue in my mouth. I just reqcted naturally and kisssed him back we tongued each others mouths and it felt strange because he was stubbly, after a while I unzipped him and sucked his big cock, I licked his bell end and could taste his pre cum, after a while he came in my mouth,his sperm was warm and salty, the next day I felt filthy.
