Professor Helly Hellfire, Johnny's teacher, can tell he's not very interested in quantum physics from watching him in class. She informs him that she wants him to succeed during their private discussion about it one day in her classroom. And since the chalkboard's mathematics and figures aren't aiding in that endeavor, she suggests a more hands-on strategy that involves his hands all over her large tits and his buckyballs in her mouth. The enormous dick goes in-out, in-out, in her hot pussy. It's possible to like quantum physics.
