Mayu, a rookie tutor. I head to the student's house I'm in charge of for the first time while being nervous. The house was rich, but an erotic parent and child... A father who sends an adult toy to his son who is worried about his teacher's breasts and can't concentrate on studying. She is in trouble with money, and Mayu, who has a personality that she can't say she doesn't like, is at the mercy of this parent and child.
