駄目だと思う程に燃え上がる背徳の校内不倫。クラスで一番可愛い芽衣に告白された担任の僕。一度は断るも、積極的なアプローチと若い身体の誘惑に抗いきれず、昼休みにだけ密会する日々が続いていた。結婚して妻もいる、こんな関係が許されるわけがないと分かっているはずなのに、気づけば彼女の淫らな誘惑に溺れてしまっていた…。本当にごめんなさい…。

The more I knew it was wrong, the more my forbidden passion for this school affair intensified. I, the homeroom teacher, was confessed to by Mei, the prettiest girl in the class. I initially refused, but I couldn't resist her aggressive advances and the allure of her youthful body, and we continued our secret meetings during lunchtime. I'm married and have a wife; I know this kind of relationship is unacceptable, yet before I knew it, I was succumbing to her lustful temptations… I'm truly sorry…
