The Great Gasperini
While doing your girlfriend from behind, you tag team with a needy buddy to switch off without her knowing. You then leave bedroom with them still going at it. You then go outside and video your friend doing you partner from behind. You then end it by knocking on the window while still videoing them for her reaction.
Hey if your not busy tonight, do you want to help me pull off The Great Gasperini tonight so I can dump my new girlfriend?
