1. Penny is a martial arts instructor who is having fun teasing her male students about their delicate little balls! She lets all the boys know that they all definitely need the smallest cup size before she mocks the way they usually react to getting kicked between the legs. Penny's final message of caution to the guys before letting the female students loose on their crotches is that their protection is useless if they pop a boner! 2. Shopping for an athletic cup is probably something a shy guy should do online, not with the hottest female trainer at his gym. Especially one with an appetite for busting balls and embarrassing weaklings. When scrawny Sammy timidly asks if any male instructors are on duty femdom fitness expert Penny smells an opportunity for humiliation. When she makes him admit that he is looking for crotch protection Penny knows this wuss is about to give her a very entertaining work day.   3. 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.
