In the dimly lit, cold corridors of Analtreat's Anal Asylum, a feisty young woman, dubbed 'Kitten', is brought in for a 'painful treatment'. She's stripped naked, her petite body quivering with fear and excitement. Her tight, unyielding asshole is the focus of the depraved doctors. They prod and poke, stretching her limits with their fingers and toys, pushing her to the brink of tears. But Kitten's resilience surprises them; she takes their hardest thrusts, her cries turning into moans of twisted pleasure.
