filthy simian
A sexual position where the female supports herself on her shoulders with her legs spread upward in a "V". The male likewise spreads his legs widely enough that each partner's respective reproductive organs are in close proximity to each other. The male bends his penis downward to penitrate the female. Once coupled, both parties deficate and procede to copulate.
I had the best weekend, but I now have a nasty rash from the filthy simian I performed with X.
