Rin is a student who loves me, her homeroom teacher. Not only is she a teacher, but she also knows that I have a wife, but she approaches me with a devilish expression and seduces me. "You don't really want to, do it..." "Hey, teacher, do it more..." I'm in a position where I definitely shouldn't do this... She invites me to a hotel, and we end up having forbidden sex over and over again.
