Shizuka is asked to take care of Kazumi's son, Satoshi, while her mother's friend, Kazumi, is in Okinawa for a relative's wedding. Satoshi says he can't move because he fell on his bicycle a week ago and was injured. "If you're in trouble, don't worry about it." Shizuka agrees and goes to Kazumi's house to take care of her, but she makes a big mistake because of her huge boobs!
