Professor Kimmy Granger knows the secret of holding on to her class's attention. She begins her first lesson in Sex Ed 101 by bringing her assistant, Adriana Chechik, to class for a hands-on demonstration. Kimmy emphasizes the importance of stimulating the pussy to get it nice and wet as she fingers Adriana and spanks her with a ruler to make sure she's extremely horny before fucking her with a dildo until she squirts! Then it's time for a volunteer, and star student Duncan Saint is eager to take a turn. He's so good at eating Adriana's pussy Kimmy decides he's ready for the advanced lesson of fucking them both! Duncan finishes with an F for Facial, but in this class that's the best grade you can get!
