In the dimly lit "Anus Asylum," a bound, squirming girl is brought in for a "cure" that's more pleasure than pain. The doctor, a dominatrix in disguise, teases the girl's tight hole with her gloved fingers, making her moan and beg for more. She replaces her fingers with a thick, black dildo, pushing it in inch by inch, until the girl's asshole is stretched wide. The doctor smiles, knowing the girl's "treatment" is just beginning.
