After losing her husband in a traffic accident, Rin had quit drinking and was living in deep mourning—until the day her father-in-law, Youji, came to visit. Youji, who had always shown an unnaturally intense interest in Rin even before his son's death, took out all his rage over losing his beloved son on her. He forced her to drink alcohol, knowing full well that once Rin drank, she transformed into a lustful woman. Minutes later, as the alcohol coursed through every part of her body, Rin found herself with the man she despised most—her father-in-law. What follows is an intensely passionate encounter.
