This mistress had beef with this tiny man for being clueless. She used her giantess feet to crush and smother him to make sure he learned his lesson the hard way. She did not want him to think that it was ok to be clueless and so she hoped that the pain as well as humiliation he felt as she trampled him would teach him the lesson that he needed to be taught.
Mistress Nyx had beef with this guy which she had to settle as soon as she could. She did it in a way he had never had it done before. That is why she used her giantess fetish to do it because she needed a quick and easy win. So she trampled him into a tiny man and she scared him shitless. He behaved as she wanted immediately after the punishment.
