Katsu receives a phone call from her mother-in-law, Saori, and goes to her aunt Miyuki’s house to pick up her forgotten items. There is no response even if I ring the bell, so when I go to the backyard, Miyuki may be masturbating with a vibrator while watching TV! !! I was overwhelmed by Miyuki’s appearance and tried to escape, but I was forcibly invited to my house. Eventually, Katsu drowned in Miyuki’s abundant physical charm.
