A momentary impulse to shoplift takes a drastic turn, throwing Yumi's life into chaos. Her neighbor, Kaibu, seizes the opportunity to target Yumi's big breasts, gradually spiraling out of control. He forces her to undress herself, spreads her embarrassed, quivering pussy, and bombards her with lewd, degrading words. He proceeds to molest every inch of her body in increasingly depraved ways. Ultimately, he makes her assume a dog-like position, completely stripping her of control.
