I go back and forth on this one, but I have to admit I have cum several times while masturbating while thinking about a man peeing on my tits and it running down between my legs. When I am thinking about a dominant man i something think about it making me clean his cock with my mouth after he pees. *blushes*
I get very turned on thinking about pissing over a masturbating woman, playing my stream of hot yellow piss over her tits and down to her pussy. I also get very hard thinking about a sexy lady peeing on my cock,chest and face or even just sitting there pissing and then letting me lick and suck her pussy clean.
