Rieko, a woman in her prime, lives happily with her beloved husband, but recently her older husband has been repeatedly having sex, and Rieko is no longer satisfied. Just then, her husband's younger brother, who was laid off, comes to Tokyo to look for a job and stays with her for a while. The brother-in-law's job search is not going well, so the three of them have a drink to cheer him up. Soon, the drunk husband is taken to the bedroom by the brother-in-law and Rieko. Then the brother-in-law hugs Rieko and kisses her. The next morning, Rieko and her brother-in-law look a little awkward as her husband says he is drunk and has no memory of the past. That night, while her husband is taking a bath, Rieko is hugged and kissed by her brother-in-law again. She resists, but when he presses his hardened crotch against her, she is confused and ends up sucking on his hardened crotch as he tells her to.
