Every late-night nurse call becomes a signal for another assault. My devoted, gentle, big-breasted girlfriend—a beautiful nurse—first gives herself to a wealthy patient, who then uses the secret to blackmail her. One patient after another strips off her uniform, demands titjobs, rapes her, and creampies her in the deserted midnight hospital. Although she has a fiancé, the repeated abuse gradually conditions her body to become aroused whenever the nurse-call bell rings.
