A madhouse inmate, a kinky woman with a hunger for extreme pleasure, is strapped to a table for her daily 'therapy'. The staff, dressed in clinical white, watch with hardened cocks as a massive, veiny dick is brought to her eager asshole. The patient's moans echo through the room as her anus is slowly stretched, her tight ring of muscle resisting before giving way to the relentless invasion. The drilling intensifies, her asshole gaping and slurping as it's pummeled with force, her cries of pain and pleasure mixing with the wet, smacking sounds of her kinky treatment.
