I'll never be a good student

Description: I don't think i'll ever be a good student as it's so hard and boring to study. but my stepmom (who wants me to call her mistress for some reason), really wants me to succeed and punishes me when i have bad grades... but i'm not sure if she ever noticed that my pussy gets wet from it everytime.. whenever she leaves the room i always masturbate a little. this time it was a bit different as she walked back into the room, like wtf?! so i got punished once again, but this time i had to read a book in the corner, while being naked, "so i get smarter".
