サイレント補習クラス

A female student who is scheduled to take supplementary classes. She was called to her teacher's personal preparation room. It was a small room adjacent to the classroom. "Don't raise your voice, there's a club activity next door." The female student, who was tied to the teacher's table and had a large vibrator inserted, silently nodded in response to the instructions. The vibrator, which was secured with a rope and underwear, penetrated deep into her body, causing stimulation the female student had never felt before. Then, in the adjacent classroom, about a dozen students gathered and club activities began, with the teacher serving as an advisor. "Don't turn it on. I'll make a voice." The female student complained, but the teacher only smiled at her.
