After she misses the last train, my best friend's girlfriend comes home with me to drink until morning. It is supposed to be harmless, but once we are both drunk, I make a move. She resists at first, then gives in to the mood, accepts me, and cums repeatedly. The guilt of betraying her boyfriend makes the sex even more intense, and we fuck until morning. When the doorbell rings, my worried friend is outside looking for her. I hide her, lie to him, and send him away—but the thought of letting her go drives me back into bed with her. Their physical chemistry is so strong that pleasure conquers her resistance completely, leaving her eager to keep sleeping with her boyfriend's best friend despite the betrayal.
