Mistress Zephy watched trampling videos and she wanted to do that. But she did not have anyone to do it to and she chose to pay someone to endure her the pain inflicted by her sneakers. The mistress had a great time as the guy agreed and she did not care about how he felt as she had already paid him for what she did to him. It was so good to her she had to do it again soon.
Mistress Zephy did not like how much of a fool this old guy was and she wanted to tame his foolishness. That is why she had to humiliate him and she did it with her converse sneakers. She asked him to lick them and he had no choice. She even tried to force them into his mouth and she nearly tore apart his mouth. He had to conform to her standards.
