Ai is dissatisfied that her husband's sex is too kind. Katayama's masculinity, introduced to her by her best friend Miyuki, and her hot gaze staring at her make her heart flutter. She says, "You're a masochist." At a later date, she visits Katayama's house with the expectation that she will be trained. She orders masturbation in front of the mirror. She gives a blowjob service to the courier. She is left naked in the parking lot. She is POV from Katayama's junior. Ai was drowning in the pleasure of her masochism.
