A young Mary Fox fucked with a professor for a good grade

Tired grey-haired teacher enjoys his deserved cup of coffee when Mary Fox comes up to him and asks to check her papers. The teacher doesn't want to do anything, he wants to relax but sweet brunette begs him so much that he surrenders to her pleads. He understands the work is full of mistakes right away and that Mary Fox needs a miracle to pass the test or maybe his special help is enough. Luckily, Mary Fox understands hints perfectly and kneels in front of the grey-haired teacher to suck and beg for his help.
