Mistress Isil and mistress Roxi were angered by the fact that this guy wanted a threesome with them. He was crude about it and the mistresses were pissed at him and had to punish him. He had to realize that they were not the kind of girls he told anything he wanted however he felt. So they trampled him with their bare feet and taught him a cruel lesson he never forgot.
When it comes to using everyday tasks to punish, this mistress is on top of her game. The mistress was so disappointed in this guy that she had to do something she had never done before which was to make him lick mud from her boots. She went out and waded in mud before she used it to punish him. And he stood no chance against her as she did her thing to him.
