At that point, the urinal sitter grabbed the dirty cock and pulled the guy closer and shoved the cock in his mouth. The guy came up the bottom's ass, and when he pulled out there was visible santorum on his cock.
Eventually a guy facing the urinal-sitter dropped his pants and a guy right behind him fucked him raw. It got increasingly crowded until it was shoulder-to-shoulder. Also I did resent that he was GOING to make everybody pee on him whether they were in the mood or not). I became pee shy for the first time in my life. (I found this more challenging that I should have. He was sitting in the trough urinal (good for him not being ashamed of his desires!) and would reach over and aim the stream at himself. I LOVE sleazy bathroom sex but one guy really gave me pause. I was there one weekday afternoon and went into the men's room to take a leak. Dark, sleazy decor, real rock music on the jukebox.
The Hole in the Wall Saloon in San Francisco in the mid-90s had a lot that qualifies it for inclusion here.
