Yuki thought she could have sex with her boyfriend, but when she is introduced to a man who is her boyfriend's friend, she becomes displeased. He begins to blame the man who is a masochistic man as his boyfriend tells him to do. While he's doing the act, he inserts himself in front of his boyfriend's camera and starts shaking his hips. In the end, she is a boyfriend-approved NTR who is made to cum by a masochist man in front of her boyfriend.
