Devoted to protecting her sisters, Rika sacrifices herself to a debt collector. “I’ll do anything you say, so please leave my sisters alone,” she pleads before stripping naked in front of them, sucking the man’s cock, exposing her pussy, and letting him fuck her. Her sisters spit on her and cover her body with obscene writing as the humiliation continues. In the end, she becomes a cock-crazed sex toy and even her sisters abandon her.
