A boy who works hard with a tutor Naho and a three-legged race to pass a first-class university. Naho is talented and good at teaching, but she loves to be sexually harassed by naive boys, and without exception, boys also suffer from it. Naughty words are whispered in the ear with sighs, and plump boobs are pressed against the body. With this, the adolescent boy can not concentrate on studying for the entrance exam, and at last the boy is invited by Naho, but he gets a lot of vaginal cum shot.
