815WOMC-014 Having sex with a stranger in front of my boyfriend

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. Her boyfriend tells her to blame the man who is a masochist, and she begins to blame him. While doing the act, she inserts it in front of her boyfriend's camera and starts shaking her hips. In the end, she is a boyfriend-approved NTR who is made to cum by a masochist man in front of her boyfriend.
