Mistress Jacky makes a lot of money with her hands and she has christened them her moneymakers. And since she depends on them to make a lot of money, she wanted them to be in the best of shapes. That is what led to her moisturizing them and ensuring that they were in the best of shape for her to use them as she was planning to on a money slave she had identified.
Lady Kassy felt that her hands were too soft. She wanted them to be hard so that when she slapped someone, it would be very effective. So she waited for this loser to mess up and when he did, she slapped him repeatedly. At first, it was not painful to him. But as she went on, the pain started to get intense. And she did it over the course of several days and they started to harden.
Lady Amy did not like what she had caught her slave doing. He was jerking off in her kitchen and she was pissed because she did not want him to do that anywhere other than his room. She took him to his room and she punished him by hand crushing him. She also choked him and made him pee his pants for him to realize how serious she was about it.
