Mistress Nica and her friends Aurora and Nia wanted to dominate this guy using boots. But they had never done it before and it was not an easy thing for them as they did not want to look like amateurs as they trample the guy and humiliated him. The poor guy had no choice but to do what the mistresses wanted him to do. He regretted what he had done and he begged them to stop when it became too painful.
This guy thought he would turn on mistress Nica and her friends using his dick. He thought that just by being naked, they would be turned on and want him, but it was the opposite as they were repulsed by his behaviors. So they had to punish him and they did so using their high heels which they used to trample him with. He was also trampled with their bare feet.
Mistress Nica had tried to tolerate this guy but he kept on pissing her off. And when she got tired of it all, she had to punish the imbecile in a way he had never been. So she used her boots to trample the shit out of him and ensure that he felt the pain and humiliation that he deserved to. Besides the trampling, the mistress also had him lick dirty stuff at the horse's stable.
