Ueto works at a small obstetrics and gynecology hospital somewhere in Tokyo. She is a beautiful nurse who is earnest in her work, and is trusted by both patients and colleagues for her attentiveness and kind smile. However, she has a secret that even her close colleagues do not know about. She has a bad habit of seducing the husbands who visit the hospital, hiding it from their pregnant wives... The men, whose wives have refused to have sex with them, saying "No sex until the baby is born," have accumulated sexual desire and stress, and in the semen collection room, in the hospital room, and right next to the delivery room where the wives are giving birth... they betray their wives who are fighting the pain of childbirth and easily fall for Ueto's temptation. Ueto smiles gently as she looks with satisfaction at the faces of the men who give in to pleasure and climax with their goofy wigs. "When I see happy couples, I feel like being mean to them..." Contains four stories of infidelity in the hospital by sleazy husbands who are entangled with evil nurses.
