A request arrives from a man who runs a credit bureau in Tokyo. It was from a person who owns an apartment and said, "I want you to investigate because a female college student who is a shopkeeper is being stalked." The agency will install a hidden camera in her room. What was reflected there later was the appearance of the apartment owner's small son coming to play in the female college student's room. My son pretends to be innocent and repeats shameful acts to her, such as rubbing her big tits! At the end of the day, the female college student and her little son have a physical relationship.
