My grades were in the red and I hadn't attended enough days, so I was in a hopeless situation, and my homeroom teacher, Hiiragi-sensei, reminded me not to tell anyone and secretly summoned me to the hotel. To be honest, I was surprised since she wears glasses and seems to be a straight-laced person, but it seems that she will provide special private tutoring so that she doesn't repeat a grade. I was fidgeting, not knowing what to do, when my girlfriend's teacher touched my skin, giving me goosebumps. A side of the teacher that I have never seen before. As a virgin, I was thrilled.
