This guy was irresponsible and he had the audacity to try and associate with mistress BlackDiamoond as well as with lady Alice. That is how he found himself in hot soup and he regretted his association with them. The mistresses turned the guy into a trampling slave and they head trampled him until they were satisfied with what they had done to him. He was never irresponsible again after that.
Mistress BlackDiamoond had a score to settle with this guy and she made sure it was settled in the most weird way possible. And the mistress did this using her shoes. She crushed the guy and then head trampled him as painfully as she did. It was cruel and it was humiliating but she did not care. All that mattered to her was that he learned his lesson and he did not have a choice but to learn it.
