Horse Man's Revenge
You're fucking a girl in the ass and she tenses up so tight that the inside of her large intestine rips off onto your dick and then you start fucking her in the vagina, using the intestine as a condom so she doesn't get pregnant.
Dude, did you hear mercer hit her with the horse man's revenge last night?
Her ass will be sore for a fortnight.
