Yumi is hospitalized due to appendicitis, but her post-surgery recovery progresses smoothly. However, the pubic hair shaved for the operation begins to grow back, causing discomfort and itching. Unable to endure the sensation, she resorts to masturbation for relief—but her lecherous attending physician, Takamori, catches her in the act. He touches her groin, and her sensitive body instinctively reacts to the stimulation. Takamori persistently caresses her, drawing out her pleasure. Once awakened, her body grows even more sensitive, and her craving for pleasure becomes uncontrollable. Lost in a sweet, dreamlike state, she surrenders herself completely, yearning for more of his touch.
