What if, during class, a pubescent boy gets inexplicably aroused and ends up with an erection without even realizing it? Imagine a big-titted, kind yet naughty teacher at school who quietly seduces her students. The school atmosphere would become constantly lewd and erotic. Haru Kawamura, a slender teacher with H-cup breasts, seduces students from morning assembly to after school. Beneath her gentle demeanor lies a surprisingly aggressive, carnivorous nature, tempting students at every moment of their youth. Whether in the classroom or the nurse's office, no one can resist her allure. If such a teacher existed, school would be so thrilling that every student would attend daily, never missing a single class.
