While facing a window, a man and a woman have sex dogystyle. Unknowingly to the woman, you slip it out in the middle of intercourse and switch places with a friend. You than proceed to leave the room and run around to the window. As your friend and the woman are climaxing, you knock on the window and wave to them.
You played the dirty neighbor perfectly last night.
