A peculiar asylum becomes the setting for an unusual form of therapy, where a naughty nymphomaniac is taken in for treatment. The therapist, with a sadistic streak, uses her patients' bodies as his playthings, focusing on the tightest of holes. He begins by rimming the nympho, lapping at her asshole, before proceeding to facefuck her, shoving his cock deep into her throat. Next, he drills her ass, stretching it wide and making her moan in pleasure and pain. The therapist's unconventional methods leave the nympho begging for more.
