TNTP Pee in the shower.

From Create Your Own Story

You proudly plant your feet either side of the drain, and unleash. A yellowish strain merges at first from your vaginal lips into the cascade of clear water running down your tummy and thighs, then breaks apart and splatters noisily about your feet. The release, the warm water, and the sonic confirmation of your abandon take you to a place of mild ecstasy.

Your bladder spent, you rinse off and towel down.
