Several years have passed since he entered an arranged marriage with Yuki, a teacher. With almost no sexual experience before meeting her, he still becomes nervous and fails in bed, leaving the couple sexless. One day Yuki tells him that adult-student role-play characters at school secretly filmed her and admitted masturbating while fantasizing about her. The revelation sends a shock through both his mind and groin. His desire to watch his embarrassed wife being humiliated grows uncontrollable, so he invites her to a porn theater where he intends to share her with vulgar strangers.
