Our protagonist is a broke college student who's struggling to make ends meet. He's sharing a dorm room with his promiscuous friend who suggests a rather unusual solution to his financial problems. Seems his roommate has been hooking up with his ex-girlfriend, who's more than willing to get down and dirty with anyone for a good price. The plan? To let her service him in exchange for cold hard cash! The dude is initially hesitant, but the thought of some extra cash and watching his ex get pleasure from another guy is too much to resist. He agrees, and before long, his roommate is getting down and dirty with his ex, all while he's watching and stroking his own cock. The scene escalates into a wild threesome, with the dude joining in and fucking his ex-girlfriend. It's a wild ride of hardcore action that leaves everyone satisfied and the main dude with a few extra bucks in his pocket.
