You are having sexual intercourse with a woman and you are thrusting your penis into her anal cavity. Just before you are about to excrete manjuice, you pull out and spit on the woman's back so that she thinks you came. Then, as she turns around, you jack off in her face, leaving a sticky, smelly mess.
Woman: "Are you gonna cum?"
Man: "Yes honey, right now." *spit!*
Woman: "Wow, that was some great sex! Let me just turn around and-"
when you are fucking a girl in the ass, in the doggy style position, you spit on her back and when she turns around because she thinks you came you blow the load in her face
