A sadistic nurse who met a patient during their hospitalization invites them to her home under the pretense of checking their recovery. Under the guise of treatment, she strips the patient naked and takes photos of their penis and anus. She wraps them in plastic wrap and administers electric shocks, performs enemas and denies bathroom access. She forces the patient to masturbate in front of her or watches them do so, submerges them in the bathtub for water torture or near-drowning, stimulates their anus with dildos and strapon dildos, and unleashes full-force swings with a riding crop. Even after ejaculation, the penis vibrator torment continues, and she makes them drink their own urine. What began as playful teasing gradually escalates into increasingly severe torment. She begins treating the patient like a servant, declares they require ongoing treatment, imprisons them in her home, uses them as a sex toy, and progressively tightens her psychological and physical domination over them.
