The Montenegro Squirrel

The Montenegro Squirrel is a sexual act where the male is naked and does a headstand facing the wall while the female attempts to throw a playing card so that it sticks in the males butt crack. Once this is achieved, the male falls backwards causing the card to be jammed into his anus.

The female proceeds to take a dump on the males stomach while performing the reverse cow girl and making squirrel noises
