Mistress Mikaila was tired of trying to convince this guy to agree with her way of doing things. And that is why she opted to humiliate him instead and get to have her way as opposed to begging him. So she used her boots to stomp on him and as the pain got to him, he realized that he had to do things her way if he was to get her to stop.
When it comes to trampling fetish, there are a few mistresses who get it. This mistress is one of them. She is the kind of mistress who loves to have fun and she does what she can to ensure that she humiliated losers for what they have done and not for her own enjoyment or because she is bored. She takes time to do what she likes and she does it well.
