Lady Victoria wanetd this guy to know that it was not ok with her for him to be late and especially when it was happening all the time. That is why she chose to use her humiliation femdom to teach him a lesson. It had to be a lesson that he had never been taught before and she cruelly punished him for all that he had done. He never repeated his mistakes.
Lady Victoria did not want to dominate this guy. She did not want to punish him in any way but he was driving her to do it. The mistress had to send a message and she did this by forcing him to check out her boots and then told him that she was prepared to ball bust him with the same boots. He was scared and he stopped pissing her off.
