PRTD-001 A group of students specifically raped the homeroom teacher

I am being bullied by some annoying people with high tension, who immediately resort to violence. I didn't know that my room was their gathering place, and Mr. Sakurai was hoping to visit my house. I can only watch the teacher, the only one supporting my future, being trapped and stripped bare. For some reason, the bottom of my pants is reacting violently even though the teacher has received more humiliation than I have.
