Veronica Stone fucking in the desk with her piercings

Despite her best efforts to study and pay attention in class, Veronica Stone is unable to get anything better than a "D" in Professor Lawrence's class. Thankfully, he's come up with a new grading system just for her: D stands for tits, C for hand job, B for oral, and A for fuck. What will it be, Veronica? Are you going to accept a "D" or a "D-i-c-k" for a "A"?
