Tamaki, who works at a gynecology and obstetrics hospital somewhere in Tokyo, is a beautiful nurse with a calm and bright smile. Her attentive care towards pregnant women is highly praised by patients and she is trusted by her colleagues, but Tamaki has a secret that she cannot tell anyone. She has a bad habit of seducing husbands who visit the hospital, hiding it from their pregnant wives... Men who are sexually frustrated and stressed because their wives refuse to have sex with them, saying "No sex until the baby is born," easily fall for Tamaki's temptation in the semen collection room, in the hospital room, and right next to the delivery room where the wife is giving birth... betraying their wives who are fighting the pain of childbirth. Tamaki smiles gently as she looks with satisfaction at the faces of the men who give themselves over to pleasure and climax with their silly 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.
