Mistress Betty could tell that this slave was not well trained and she did not want to take a long time training him. So she did what she does best and she trampled him with her riding boots. The poor slave was naked in a lot of pain. This in turn made him more attentive and that is how she got him trained in a relatively short period of time.
Mistress Betty knew that a scared slave was a good slave as he would be obedient and would not ask questions. So she took her slave to the stable even though he had done nothing and she stripped him naked and turned him into a human pony. Not only did she ride his bare back, but she also had him lick her dirty boots until they were clean. The mission was accomplished.
