A forbidden honeymoon love affair between teacher and student that cannot be told to anyone. In the early morning, I inserted a dildo into the empty staff room, and hid in a private room in the toilet during lunch break. After school, I had vaginal sex as usual in an empty classroom, received sexual harassment instructions during club practice, and asked each other to become men and women at the teacher's house before going home. I could not stop the love affair that made that love burn because I knew it was a love affair until I graduated.
