This is a phenomenon similar to backwash. It occurs when a male ejaculates in the vagina of a woman and as he pulls out there is some residual sperm mixed in with vaginal lubricant.

Cockwashing station :

When you are sitting on a toilet and a chick fucks you so hard that you lean back and break the toilet tank. Thus causing the water to gush everywhere and wash your cock off as well. Extremely helpful if a tidy bowl cleaner is inside the tank - as this may reduce risk of pregnancy and std's.
I waited in line to use the bathroom at the club forever! Bitch walks out smiling, looked like she PISSED her pants . Get in the stall and there's my man trying to wipe the water off the floor. Oh hell no! Fireball whore just opened up a Cockwashing station!"
