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.
