WOMC-014 Fucking a stranger in front of her boyfriend

Yuki thought she was going to have sex with her boyfriend, but when he introduced her to a man who was his friend, she got upset. Her boyfriend told her to dominate the man, who she said was a masochist, and so she started to dominate him. As they acted, she inserted him in front of her boyfriend's camera and started to move her hips. In the end, she was made to cum over and over again by the masochist in front of her boyfriend, in an NTR scene approved by her boyfriend.
