Thanks to Jim Powers' perverted comedic genius — and a few notable cuties — this series is playing at the top of its game.

Sasha Knox makes a big impression with her schoolgirl charm and hot little bod as she explains to her best friend's dad, proctologist Dr. Alec Knight, that her butt hurts because her boyfriend wanted to try something new. "Is there anything you can do to help?" she asks during an impromptu exam. "Why yes," he replies just before burying his face in her ass. Elsewhere, step-mom Chelsea Zinn and daughter Tiger give teacher Herschel Savage plenty of good reason to reverse his disciplinary action.
