JUR-193 I was taught in school that the teacher's naked body is a 'blackboard'. Graffiti homeroom Yukinari Takeno

"Let's write a message on the blackboard (teacher) to remember graduation."
My body is a male student's blackboard.One day, I was strict with my students, and I was given a grudge from one student.Then the students called me to the club room and I was raped.Not only did he do it, but he was "cracking" my body like a blackboard...The act was carried out every day during class and after school, and gradually I became awakened to the joy of being defiled.
