A peculiar therapy session unfolds in the derelict corridors of an asylum, where a voracious nurse specializes in unconventional treatments. Her patient, a timid young woman, is hesitant at first, but her curiosity and arousal grow as the nurse binds her wrists and guides her to the edge of a cold, metal bed. The nurse's gloved hands explore the patient's body, focusing on her trembling ass, then her tongue follows, lapping at the virgin hole, teasing it open. The nurse then introduces an array of anal toys, each one stretching the patient's ass further, before finally, she brings in a strapping orderly, his cock rock-hard and ready for the patient's tight, new hole.
