Your girlfriend is a few feet behind you, fucking another man. Meanwhile, her best friend describes what's happening and teases you by demonstrating on her fingers. When you get turned on, she tells you that she's going to make you cum on her tits before your girlfriend makes him cum inside of her. (Originally a custom; Some themes of cuckholding/groupsex. Shows breasts, finger sucking, finger stroking, eye contact, and lots of talking. Voiceover to simulate your girlfriend getting fucked off-screen.)
