A group of several girls take their friend (girl #1) out to a bar for her birthday. She brings her boyfriend (the only male in the group). As the night goes on, they get pretty drunk. One of the girls (girl #2) says she bets that she can rape a guy. (This girl is wearing a strap-on underneath her pants). To the guy's dismay, his girlfriend takes up that bet. Girl #2 proceeds to rape the guy. At first, the guy thinks she' not serious. When it soon becomes clear that she is, he thinks that he can fend her off, but it turns out that he can't. As she pins him down, pulls down his pants and enters him from behind, he pleads with the other girls to help him. But they just watch.
