Would you prefer fail or have cum on your face?
Sometimes I hate being a professor but at other times I really like it, like today, for example there are some girls who will do anything to pass.
Sometimes all it takes is a few bucks to get a slut like her to let you cum on her face, sometimes after you cum on her face, they're so happy they don't even want the money, just like her.
If you are a teacher, you must teach your student everything so she is prepared for the future, that includes teaching her how to take a good cum on her face.
