Lovely secretary knows her job perfectly

Movie description: Izzy Taylor needs to boost the F she has in Professor Knight's class to a hire grade, so she visits him during his office hours. But he tells her that he's not able to give preferential treatment to just one student, so he can't really help her out. That's when Izzy changes his mind by stroking his big hard cock and putting it in her mouth and then fucking him on his desk!
