IQQQ-032 A married teacher, Rinko Okae, gets ten times wetter in a lesson where she can't scream.

Rin was indulging in the unbecoming act of a teacher, having a physical relationship with a student. It was exciting for her to touch a young man's sexual desire, and secretly piling up a meeting was immoral. However, the situation changes completely when her student asks for a relationship at school. She desperately tries to calm her down, but her student, who has been trained by Rin and turned into a sex monster, won't stop. Rin was poked by her student in a corner of the school, and all he could do was desperately suppress her voice from leaking out.
