I used to have a fantasy when I was a little girl that I was on a gameshow and had to hold in my piss and they would turn the water up on my pussy higher and higher and in my head I won a bigger prize if I withstood a stronger setting for longer. It was a stall shower but I can't cum while standing so I'd lay like I was doing a handstand while doing this. Sometimes I'd soap up the floor and spin on my ass as well, as a treat.
