*Custom* Your girlfriend has come up with a great way for the two of you to go on a nice vacation together. She will make a bet with that cocky guy from her work. What is the wager? If she makes him cum he will pay for the vacation, but if he makes her cum he gets her. Your girlfriend knows you can't resist her feet, so she manages to get you on board by telling you to jerk off to her foot movement. Your girlfriend starts off so confident in not cumming for him, but his cock is just so big and he's fucking her like she's never been fucked before. She just can't hold it back anymore, and you accept that your girl is now his. You watch her get fucked mindlessly and become his toy.
