START-298 | I'm keeping my teacher soaked in 'sensitivity doubling liquid' on campus lol I restrained her with her legs spread wide and a fixed vibrator, and made her cum so hard her pussy became numb Nao Satsuki

Nanao is a new teacher who has been put in charge of a problematic class dominated by bullies. Due to her strong sense of justice, she tries to protect a student who is being bullied, but it turns out to be a trap. Nanao is covered in liquid in the gym storeroom, tied up with her legs spread wide, and tortured with a vibrator. She desperately tries to keep her sanity, but as the liquid takes effect, she can no longer resist the pleasure...
