Driven mad by the constant moans of his neighbor's wife, the man next door transforms into a beast. As soon as he presses the intercom, he barges into her house and pins down Kana, his neighbor's wife. Kana is initially confused and resists the sudden intrusion, but when she's confronted with the man's erect cock, she quickly becomes aroused. Forgetting her resistance, she mindlessly sucks him off. Her pussy, made sensitive by days of masturbation, and his cock dripping with precum, they give in to their desires and engage in endless sex.
