Professor D isn't quite sure what to do with Barbie. She's got the highest average in the class, but she keeps insisting on hanging around trying to get some extra credit. When Professor D breaks the news that her grades can't get any higher, she decides to show him some of her other skills - like how she can fit her prof's meat ruler down her throat. After pounding her pussy deep, Professor D may not be able to give her extra credit, but she's at least earned his massive load all over her face!
