Chizuru, a married teacher with plump big tits, is the mother of the protagonist's friend and his homeroom teacher.

She is serious, cool, and strict, and her students are afraid of her, but the main character is attracted to her eroticism and spends his days getting horny and indulging his desires, even while he is being scolded.

One day, when he went to a sugar mama website in search of a tasty encounter, he came across the teacher he had been longing for, Ms. Chizuru. The protagonist, who has a weakness for her, presses her to let him fuck her one time as a price for keeping his mouth shut.

Chizuru is conflicted because she can't do such a thing with one of her students, but she is also lonely and frustrated enough to turn to sugar mama activities, so she finally agrees to do it. She can't let this chance pass her by!

The hero fucks Chizuru with all the vigor of a young male and corrupts her ripe and erotic body in one shot. She feels guilty about her husband and son, but she can't resist the tingles in her body, and he thoroughly fucks Chizuru whenever he gets the chance!

The best day of his life begins as he turns the married female teacher of his dreams into a masturbating bitch teacher.
