■Myomochi, a Daisho (high school student) who was quirked by Oyaji's thick tech

The serious female college students, Koi and their boyfriends, were not satisfied with the situation where they could not have sex well because they had a relationship with each other at virginity. One day, an old father's friend, Uncle Miyoshi, visits the house and has a physical relationship with drunkenness. As the body and mind of an outstanding middle-aged man became melodious in many ways, and on that day it became a goofy and quirky sensitive constitution, I began to seduce the middle-aged man by myself without being able to restrain myself.
