The son has long been curious about his mother's voluptuous body. Following his male hunting instinct, he devours his mother's body, but is captivated by the protuberances atop her huge breasts. Driven by curiosity, he uses a milking machine and other tools to stimulate her nipples until they develop into new erogenous zones. At first, the mother resists violently, but gradually she begins to arch her back at the touch of a finger... She begins to accept her forbidden relationship with her son.
