There is a young perverted tutor who secretly steals the bras and panties of the female students he teaches to smell, that is the shadow of the tutor in this movie. He doesn't even stop there, he even entices Morimoto to masturbate with a sex toy he brought from home so that she is stimulated by the pleasure, from which he can freely take possession of this plump, smooth body without any resistance or being discovered by the parents. The actions of this perverted, lustful tutor are very condemnable, he is good at teaching but not teaching badly.
