Kaoru remarried to a man with a child half a year ago and became the mother of her young son Atsushi. Kaoru wants Atsushi to experience various things against Atsushi, who stays in her room and only plays games. One day, in the early afternoon when her husband is not there. Kaoru asked Atsushi. Atsushi-kun is a virgin, right? Kaoru's sudden remark surprises Atsushi, but after a few minutes he safely graduates from being a virgin. With a brush that is too comfortable to envy all men in the world.
