This guy was acting as if he knew everything and that he could not do any wrong. But when she gave him a chance, he did plenty of wrong and she was not amused by any of it. So she turned him into a foot slave and she dominated and cruelly punished the guy for her own fun. That is why and that is how she used her trampling fetish to get him to change. He even had to endure her pee and her facesitting.
