This guy was selfish and lady Victoria did not want to associate with him. She had to make sure that he learned never to piss her off again and that is why she went out of her way to facesit him and smother him. The objective was to choke him a little with her ass and make him panic as well as get scared, which is what happened. He learned to stop his selfishness.
This guy betrayed lady Victoria and she had anger in her which she had to get out. And it would have been unfair to make someone else suffer the consequences that the guy needed to suffer so she made sure to take out her anger on him. She cruelly ass smothered him and had her friend trample him with her high heels. It was a cruel and painful combo but it worked.
Lady Victoria had to deal with this troublesome colleague and she did it in a way he had never expected. He had never thought she was capable of doing such a thing but she was and she made him find out the hard and cruel way. He tried his best to beg his way out of it but she would not hear any of what he wanted to tell her.
