Poor little Sam got kicked so hard in the balls at karate class that he had to get checked out by a doctor. Unfortunately for him, this particular doc finds his incredibly embarrassing situation to be quite hilarious. She giggles at the size of his little package and even compares it to her much larger boyfriend. She takes away his pants and underwear so she can make him try on different athletic cups. She delights in pointing out that he fits perfectly in the boy sizes instead of the men's. The doctor then gives him a series of painful taps and smacks to his balls because she wants to check how well they protect him and because she thinks his little grunts of pain are funny. She does not let him leave till she drives home the lesson that boys are just too delicate between their legs to ever go without protection.
