When I forgot the erotic book I borrowed from my friend in the classroom and went back to pick it up... It all started when I saw the serious and unfriendly class president masturbating while looking at the erotic book.Grab your weaknesses and do naughty things... If you talk to me with such a light feeling, "You're telling me to rub your breasts, right?"After that, I was secretly made into a slut and a sex slave in every place in the school, such as the infirmary, the toilet, and the library.
