Bound and helpless in the peculiar asylum, the uninhibited nympho's ass is the focus of her unique treatment. The nurse, with a penchant for anal play, begins by rimming her patient's tight butt hole, savoring every crevice. She then inserts a succession of toys, from small to massive, preparing the eager hole for penetration. The nurse, her own arousal evident, takes the patient's ass with her thick strap-on, pounding relentlessly until both women climax in a symphony of moans and ass-clapping slaps.
