Knowing her Professor's weakness

Nathaly Lisseth goes to see her English Professor before the midterm because she hasn't studied at all. Normally this would mean she would fail the class, but Nathaly has an ace up her sleeve. She knows just his weakness is...her massive ass, big tits, and beautiful face. He is so easily seduced that she is getting her ass pounded out bareback right there in his office! Now she has a definite A!
