Professor D is giving Lauren a second chance at her exam. When she finishes he grades the exam right then and there and gives her a big old F. Determined to pass this time, Lauren takes his pen and adds a line to the F, making it a squared A. She asks him if he can change her grade to that. When he refuses, she takes the pen and scribbles in ‘NAL’ after the A. Professor D quickly accepts her offer and fucks his silly student up the ass..
