A shocking story of a mother and son's separated lives evolving into a forbidden relationship. Yukie Toake, 43, gave birth to a son who became the sole purpose in life for her 63-year-old mother. Enduring discrimination and workplace sexual harassment as a single mother, she heads to Yokohama in pursuit of her son's happiness. Her first experiences in the city lead to being picked up by delinquent students at Motomachi Park and immediately taken defenseless to a love hotel. At her son's boarding house, she's forcibly raped by a perverted, eccentric landlady. On the final night of her three-day, two-night journey, she passionately sucks her beloved son's cock, and they wildly make love with warm creampie penetration, driving her into such intense ecstasy that she rolls her eyes and faints.
