29-year-old visiting caregiver Shirota, despite being in charge of caring for the father, tempts the son with her huge ass and massive tits, constantly seducing him each time she comes to work. Finally, an opportunity arises—but then 36-year-old caregiver Inamori appears, continuing the seduction. While saying "no," she exposes her huge breasts and abandons her duties to the father, engaging in sex. Additionally, 30-year-old married visiting caregiver Kuchi discovers a vibrator in the room and begins masturbating. When the son sees her, he moves in, and they end up having sex.
