When this mistress noticed that she was dealing with a guy who did not like to do things the way she wanted them to be done, she knew that she had to punish this guy and do it in a way that he had never felt before. That is why she cruelly trampled the shit out of him and made sure that he felt pain and that he learned from it.
Mistress Kitty wanted to get a confession from this guy because she knew he was the one who had committed the crime. She did not want to waste valuable time and effort to try and pin it to him. She knew he had done it and all she wanted from him was how he had done it. She used her high heels to trample his hands and fingers and in no time, he confessed.
