Student Izzy Taylor wants to raise her grade and in order to do that, she has to make the professor's cock raise

Izzy Taylor approaches Professor Knight during his office hours in an attempt to improve her failing grade from his class to a good grade. He can't really assist her out, he tells her; he can't provide preferential treatment to one kid over another. Izzy then convinces him otherwise by caressing his large, firm cock, placing it in her mouth, and having her fuck him on his desk!
