Incestuous relationship, vaginal penetration of a mother in her fifties, Kanako Narita, AED-255

A fifty-year-old mother with a soft, full, white body receives a vibrator as a birthday gift from her son. The pleasurable vibrations are directed at her throbbing genitals, causing her to masturbate intensely. Witnessing his mother's infatuated state, the son develops an abnormally twisted desire for his mother's exposed naked body, greedily devouring her. Although she rejects her son, her ripe, wet vagina is obscenely moist, and the fifty-year-old mother, in a state of ecstasy, indulges in forbidden intercourse.
