You come up with...

Free rent.

"I'll let you stay here rent free," you offer. The house being a gift from your rich parents when you turned 18 in the spring.

"Shit man. I don't pay for that anyway. My sports scholarship covers that for me. If you wasn't so cock drunk you'd have known that, since the check you cash are from the university. Come on think of something. Other wise not only will Jen not be sucking your cock, she'll be sucking mine and you won't get to tonite. So what you got now?"
