Gracie "Give Me Good Grades

Gracie is desperate to get good grades in her upcoming college tests so she has asked if she can go through some of the books in your office, as she is leaning over the desk you notice that the baggy jumper she is wearing has fallen forwards and you can see straight down it to her perky tits. Gracie looks up and asks you if there is anything you can do to help her get a good mark, you decide to use the situation to your advantage and tell her that you will guarantee her an A grade if she lets you wank over her tits.
