My tutor is teacher Nana who has an extremely erotic body. Big boobs that you can see when you crouch, plump thighs that you can see when you rearrange your legs... If you have a teacher like this next to you, you won't be able to study hard, and you'll want to insert your dick into your pussy. Nana-sensei, students who are at a dead end need gentle and naughty body care...
