IQQQ-036 In a climax lesson where she can't make a sound, the married teacher Yukoko Shiraki becomes ten times wetter

Yuko was thought to be a strict teacher by those around her, but her true nature is that she loves young men. She had an affair with one of her students behind the scenes, and she enjoyed an affair after school. However, one day, her student asked for a relationship within the school for further stimulation. She tries to stop her, but her body reacts to her student's technique, which has been trained by Yuko and has improved sex deviation. She does her best to keep her voice from leaking out so that those around her don't notice. Yuko dies silently in a corner of the school.
