One day Kotomi comes home and sees some strange guy there. He asks his mother what’s wrong, and she explains: a relative and her husband are leaving on a trip, and now Kotomi will have to look after this guy for a week. His name is Ren, he is younger than Kotomi. She is immediately enraged by Ren’s impudent manner - he easily calls her by name, as if they have known each other for a hundred years. But then everything doesn’t go according to plan, and Ren ends up moving right into Kotomi’s room. After dinner, he watched enough of some scary show on TV and is now afraid to sleep alone. Kotomi, gritting her teeth, allows him to climb into her bed. There he immediately presses his whole body against her. Kotomi feels something hard pressing against her, and then Ren"s hands begin to slowly but surely become more and more explicit. She tries to push him away, but he is already deftly kneading her big tits with skillful hands, and before Kotomi has time to come to her senses, she herself begins to like it.
