Helly Hellfire & Johnny Castle in My First Sex Teacher
Johnny's bored as shit with quantum physics, and his teacher, Professor Helly Hellfire, knows it after observing him in class. So she has a private meeting with him one day in her classroom to discuss it, and she tells him that she wants him to succeed. And since numbers and equations on the chalkboard aren't helping that effort, she proposes a more hands-on approach ... one that gets his hands all over her big tits, and his buckyballs in her mouth. In-out, in-out, goes the big dick in her wet pussy. Quantum physics can be fun.
