A middle-aged couple is addicted to sex in a love hotel while their son is back home.

Even as her son Kenji grows up, Too and Honami are close friends with each other almost every day. A pinch comes to this thriving couple. Kenji was going back to work on school break. As a parent, it is a joy, but the couple who were able to play with each other day was confused. In particular, Tooru, who is in heat in his later years, cannot bear it. Even when I let my son go outside, my parents' house is lazy and it doesn't move like a stone. Toru, unable to hold back, takes Honami out to a love hotel.
