Lazy student gets anal orgasm as punishment

Sweet brunette missed a couple of math lessons and now she has to pass a little test. She comes to do it at the office of her teacher but all she can think about is his dick. She even draws his cock on the whiteboard. Sure, the teacher is not satisfied with such an answer and punishes her by spanking her. He decides to go further and to fill her anus with a pen. Even that is not enough for a lazy chick and he tells her to give him a deep blowjob and to get ready for a deep anal fuck.
