In the grim, sterile confines of an asylum, a wicked teen girl finds herself subjected to an unusual form of therapy. Her ass, a playground for pain, is stretched and filled by a sadistic doctor. He uses her tight hole for his pleasure, drilling into her relentlessly. She gags as her own ass juices are fed to her, her throat forced to take every drop. This is no ordinary treatment, but a brutal, hardcore exploration of her limits.
