Ecchi Soudanshitsu / Female Students: Special Consultation

Madoka-chan, wandering the corridors of the administrative building, caught her beloved teacher having sex with one of his students and realized that she could use blackmail to force him to sleep with her. However, that wasn't necessary, because the teacher turned out to be a real playboy who couldn't resist young and sexy students. He takes the initiative himself, and Madoka gets what she wanted. Soon her friend Rin tells her about her sexual contacts with the same teacher and suggests having a threesome.
