Mistress Amberleigh likes intelligent slaves. But this one was a dumb fool and she wanted to make sure he changed that. She had to punish him and make him associate being foolish with pain so that he could change. She trampled him and crushed his face with her boots and trampled his stomach with the same boots and left him in a lot of pain. Then she told him if he did not take steps to enlighten himself, she would do the same every time.
When a slave thinks that he knows more than his mistress, he has to be punished. This mistress did it in the most effective way possible. She had a leash on his neck and she used her boots to trample his head and push some sense into it. She also used her bare feet to trample his bare chest and his stomach. By the time she was done with him, he had learned his mistake.
