Upon learning that his son was being bullied, the father went to the bully's house to demand compensation for medical expenses. He then saw the mother who had been walking shoulder to shoulder with the homeroom teacher a few days prior, remembering she was Yumi, the other woman in an affair. When Yumi refused to pay the medical expenses, the father demanded, 'Then let me fuck you once.' Unable to refuse due to her son's actions and the affair, she agreed. The masochistic Yumi exposed her lewd nature the more she was tormented, even feeling intense pleasure from the punishment of a real penis.
