Lady Sylvia had a problem with this slave and she felt that the slave was good for nothing. She did not want to keep him around if he was going to be good for nothing to her. That is why she chose to hard trample him. He regretted what she did to him and she degraded him like never before. He never messed up again as he knew what would happen.
This mistress did not like it when her boyfriend came home drunk. She had to put an end to that nonsense and she did so using her hard trampling fetish. He was head crushed while he was drunk and she also waited for him to have a hangover and then doing the same thing. That way, he would not forget what she did not want him to do. It worked.
