Upper-decker Double Blumpkin

A dude sits atop the toilet tank and craps in it, facing forward. A woman (or man, I guess...) sits on the toilet backwards and also crals as s/he performs oral sex on the guy seated atop the tank.

What were you two doing in the bathroom so long?
I expelled every fluid imaginable thanks to getting an upper-decker double blumpkin.

Double decker

When a guy is peeing in a urinal while another is peeing in between his legs. (In a heterosexual manner)

Hey bro, we both have to pee and there’s only one urinal. Let’s hit a double decker

Double Decker

where you receive oral sex while shitting in the top part of the toilet while the other party shits on the bottom

while I was taking a upper Decker she caught me and sat down to double decker me before I could finish.
