Being a mischievous and naughty student who spends too much time taking care of herself, Tojo Natsu's academic performance is always at the bottom of the class.

In order to help her improve while not affecting the class's ranking, the homeroom teacher decided to spend his free time tutoring her at home.

However, this did not change her, but on the contrary, it had the opposite effect. She used her flexible body and super-quality sex skills to seduce the teacher. Faced with the temptation of such a young and tender student, it was difficult for her to stay calm and make a wise decision.

The two have continuously had sex on after-school tutoring days since then.
