When a man and a woman are having sex in a bed and the man lays on his back, his penis erect, and the woman jumps into the air off the mattress and tries to aim her self in such a way that her vagina lands over the man's penis (his penis entering her vagina) leaving him unharmed.

Guy 1: I think my dick is broken. I think I need medical attention.
