Mistress Enola was bored and she had to find something fun to do with her time. She chose to play with and crush tiny men for fun. She had nothing to lose by doing so as the guys deserved it. So she was punishing them and at the same time passing time and having fun. So she did it for several hours until she got tired and went to rest.
This slave needed to be tamed and mistress Enola did it with her giantess fetish. She did not want him to become unruly so she used her giantess feet to crush him and stomp on him until he became a tiny man. He was scared shitless as she trampled him but he learned his lesson and chose to abide by her instructions and her rules so as not to be subjected to the same punishment again.
Mistress Enola was angered by how abusive this guy was towards other people and she resolved to put an end to what he did. So she stomped and crushed him until he became a little man. The mistress had used her giantess feet to do it and when she was done, she was sure that the loser would not do what he had done as he would not want to go through that again.
