When mistress Enola noticed that she was dealing with an unruly slave, she felt that it was time to dominate him and teach him something he had never been taught before. The mistress cruelly trampled him and made sure she did it with her feet. As he felt pain on every part of his body, he knew he could not afford to be unruly again. That is how he changed.
Mistress Enola had beef with her brother and she wanted him to know that she would not tolerate him forever. So she went ahead and she used her body trampling prowess to trample the shit out of him. She had crushed him and made him cry in the process. He even peed on himself as she did her thing on him. And that is how she got him to change.
