Hiyori is a close friend who consulted her about her husband's unfaithful nature. She approaches her husband in anger, but seeing that he shows no remorse at all, her anger heats up. ``Is your penis so big that women come to you? If it's true, show it to me right here and now!''

Hiyori's body begins to ache at this unexpected turn of events, and she tries to get a taste of his exasperation under the guise of investigating the cause of the affair.
