Even after their son Kenji grew up, the couple Toru and Yananami remained close. They had sex almost every day. However, a pinch came to this lively couple. Kenji was coming home for a school holiday. As parents, it was a joyous event, but the couple, who were always affectionate day and night, were bewildered. Especially Toru, who was in his late heat period, couldn't stand it. They tried to send Kenji out, but their relatives at the hometown were good-for-nothings and wouldn't move an inch like stones. Unable to bear it any longer, Toru took Yananami to a love hotel.
