Hitomi, a single mother in her fifties, decided to work as a temp to support her son who was studying abroad. One day, while working late, the president said to her, "I'll make you a full-time employee," and forcibly raped her. Her son happened to be there to pick her up and heard his mother's moans when he tried to open the office door… Upon returning home, her son reprimanded her, but in the struggle, they ended up having a relationship. The "woman" inside his mother awoke, becoming addicted to sex and transforming completely. Thus, they fell into the taboo of incestuous mother-son relations.
