"Would you like to become a nude drawing model !?" One day, I heard a voice from the art class at a boys' school. Suddenly, the drawing model couldn't come and it seems that he is asking for a new female art teacher. While being ashamed to say, "For the sake of the students," when I take off my clothes, a fresh female body is revealed. Boys' school students are excited. Today's lesson is studying Shunga. Shunga paintings depicting sex customs from the Edo period will be taught in "practical skills".
