A married woman, "Riri," returns to her parents' home with her husband, but her husband has trouble at work and has to go alone. The two of them are left alone in the house, and the two nights and three days they spend together are held by their sexually ravenous father-in-law. Even in the morning, my father-in-law, who is too virile, keeps pounding my crotch...I'm made to cum so hard I could die...I feel guilty, but I accept the pleasure and the affair.
