you and you're buddy have to secretly plan this, and you have to be cool with your buddy fucking your girl.

when having sex with your girlget her over to a window, have your buddy quietly and quickly switch with you so now he is fucking the girl. then you run around outside to the window and wave to the girl
me and my bud pissed this girl off when we pulled the window switch on her
