Ever wonder what pornstars do when they have homework? They take London Keyes's deepthroat 101 class, that's what. In this awesomely entertaining hardcore photo set from Porn Pros Network she and a lovely blonde costar break out the mega-toys and practice their deepthroating technique, right up until their test subject shows up. He's a hugely hung stud who puts the girls through their paces to see if all that studying has paid off. He sinks his meat into each of them in turn, and both ladies end up with a better than passing grade at the end.
