Yoko, who was dissatisfied with her husband, Waichi, whose energy has declined due to her age, is thrilled with her old boyfriend whom she met for the first time in a long time at the reunion. Her son Keita, who was suspicious of her strangely exhilarated Yoko, saw her making a date appointment. Keita, who felt lust for his mother's woman's face, attacks unbearably. At first, Yoko was reluctant and desperately resisted, but her body reacted to Keita's relentless caressing and crossed the line between her parent and child. Yoko gradually comes to accept Keita... Where are the two headed, driven by lust beyond the boundaries of parent and child?
