While hospitalized, Aya is suddenly administered an aphrodisiac drug and, in a hazy state of consciousness, she can't resist beginning to masturbate in her hospital room. When a doctor starts fondling her body under the pretense of a medical examination, she makes expressions of reluctance, yet her body reacts abnormally. Her eyes roll back as she nearly loses consciousness, eventually reaching a point where she can no longer hold back, climaxing lewdly and repeatedly.
