The 4th exclusive work is ...Himika Nanao, an honor student, was worried. Since she is not good at talking to people, Himika's teacher, who has lived a serious life, says, ``The school's morals are in disarray, so Nanao should become the head of the public morals committee and fix it!'' I can't talk to people, I can't express my opinions, what's wrong? While she was worrying alone, she saw a student taking a nap and slacking off. She should first wake up this person and tell him to come to her class. Although she decided to do so, she couldn't muster up the courage to do so, so she secretly retrieved the erotic book from her student. Erotic books... I wonder if adolescent boys are only interested in naughty things. Well, it's a bit of a problem, but if you use eroticism as a lure, they'll probably listen to you obediently. Hmm. It must be so. It may hurt to spend your own money, but let's buy the lewd costumes listed in this book and face everyone. Yeah, let's do that. The path of thorns that Himika Nanao follows. That's when the sexual demands such as creampie and handjob occur.
