WAAA-233 Answering the phone with mom while fucking boyfriend

As a personality, naughty student who spends too much time taking care of herself, Mizuki's academic performance is always at the bottom of her class.

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

However, this didn't change Mizuki, on the contrary, it was backfired. She uses her supple body and super sex skills to seduce the teacher, facing the temptation of being such an immature student, it is very difficult to be awake to make an informed decision. The two have been having sex continuously on tutoring days after school since that time.
