Somewhere in Tokyo, in a room of a certain love hotel, there is a pair of parents and children. Asagiri and her parents were forced to stay out due to the construction of the outer wall in the neighborhood. The mother was excited about going to a love hotel for the first time, but the son couldn't concentrate on his studies because of the atmosphere of the love hotel and the sex appeal of his mother, who felt more familiar than usual. One day, my son's friend accidentally witnessed the Asagiri parent and child coming out of a love hotel.
