Mistress Gaia has no time for a slave who does not take instructions. That is at the very core of who a slave is and she did not want some dumb person she had to teach something over and over again. She called her friend and the two mistresses trampled and crushed this slave and taught him a lesson. He learned that he had to be quick if he was to escape cruel punishments.
This mistress loves to exercise. But she does not believe in going to the gym. She does not like taking her hard earned money to the gym when she can do it at her house using her slave. So she decided to trample her slave as a form of exercise. She likes to trample him using all kinds of ways and she sometimes tramples him while wearing high heels and sometimes with her bare feet.
