Femdom extortionist, Penny Barber, has simple motivations-drain wallets and bust balls. When one of her "clients" doesn't pay fast enough she is more than happy to tie him to a chair and make him find out how many slaps, punches, squeezes, and smacks his balls can take before he gives her his very last dollar. His poor little nuts only get a break when Penny stops to laugh at him for getting a hard-on in front of her despite all the pain and humilation. Mixing in some cock teasing with the balls punishment will actually make it easier to break his spirit and bank accounts.
