Its kind of a rare fetish... I dunno if I'd be willing to try that or not. I think I'd try everything once, though. Haha
I also have done this, and now I think everytime I pee in the shower I'll think of this thread.. and also how you peed in the shower while thinking of it, too. Hahah
The only place i would attempt urinating on a chick would be in the shower. One time i was with a girl in the shower and she had her back turned so being the guy i am i decided to piss on her ass for the lulz. well the water was warm so she didn't notice, so i tapped on her shoulder so she would turn around and see the dastardly deed i was performing. she said "ew", I said "lol", it was great. Then later I turned to wash myself and I feel a really hot sensation on my leg. I turn around and this chick is straddling my leg letting one flow. It was actually pretty 'hott' to watch and feel it. I actually enjoyed it!
