As a personality and naughty student who spends too much time taking care of himself, Makimura's academic achievement is always at the end of the class. In order to help her progress and not affect the ranking of the classroom, the homeroom teacher decided to spend his free time to help more at home. But this also does not change Makimura, on the contrary, it is counterproductive. She uses supple body and super sex skills to seduce the teacher, facing temptation as a young student so it is very difficult to wake up to make a wise decision. The two have been constantly having sex on the tutoring days after school since that time.
