Mayu Kuroki, the perverted mother, possesses an insatiable sexual appetite, craving any cock she can get—including that of her own son. Her deviant behavior spreads throughout the neighborhood, leading her to engage in sexual affairs with local men like the butcher, greengrocer, and liquor store owner. Constantly unsatisfied, Mayu begs shamelessly, "Give me a cock!" At the butcher's demand, she undergoes forced anal stretching with milk enemas, violently expelling the liquid in grotesque fashion. Stimulated by handjob and vigorous thrusting, she squirts repeatedly, ultimately losing herself completely during a 5-person double penetration gangbang—including her son—exhibiting not just perversion, but the raw lust of an inhuman beast.
