From today, new nurse Izumi has become an angel in white, devotedly attending to patients and doctors alike. Her voluptuous figure draws attention, and she's especially praised for her tender care with bedridden patients, bringing them to climax with her mouth. After drinking an aphrodisiac, Izumi transforms into a sensual being whose desires grow so intense that masturbation alone isn't enough—she craves the rough treatment of wild threesomes. Captivated by her allure, patients gather around her one after another.
