A story of a married woman torn between hidden desire and intense shame. To fulfill her husband's cuckolding fantasy, she hires M Yuki, the organizer of a swinging enthusiast circle, to perform gonzo-style filming. Now in her fourth year of marriage, she agrees to let another man take her, believing it will make her husband love her more. As her body is touched and penetrated, her breathing grows ragged and she begins moaning. Though she insists, "I won't say it feels good," she writhes helplessly in pleasure. Afterward, while being stimulated with a vibrator, she calls her husband. In a state of confusion, she is thrust into again—this time climaxing uncontrollably during the phone call with her husband. This raw depiction captures the inner conflict and primal urges simmering within the married woman.
