During the summer vacation, the girls peek through the gaps in their shirts and talk to me cheerfully. "Teacher, I can swim 50 meters today." The girls who speak innocently are still innocent and ignorant of dirt. A small, bulging, growing body ..., a lower body with no hair yet ... As a teacher, I was lustful for such girls, and when I noticed, I was repeating mischief. I can't forget that feeling that I had never felt before, and even today I call students and engage in obscene acts.
