JUR-419 At school, I learned that the teacher’s naked body is the “blackboard.” Graffiti Homeroom Yuna Shiina

My body is a blackboard. It all started when I scolded a student during class. He had a lot of pride and he hated me. One day, the students called me to their room, where I was violated. Not only was he violating me, but he also “doodled” on my body as if it were a blackboard… This happened every day, during and after school, and gradually I began to awaken to the pleasure of being defiled.
