This mistress was angry at what her slave had done. He had gone and gotten drunk and peed on himself in her house. She angrily used her giantess powers to crush him and to teach him a lesson. She did it till he woke up and got sober. She also crushed some food with her feet and she made him eat it. He never repeated his mistake as he knew the consequences.
Miss Taylor likes to have her way. This guy tried to say no to her and did not know what he had gotten himself into. To show him that she meant business and that nobody dares say no to her, she used her bare feet to crush the guy and turn him into a tiny man. She then tormented the little man and told him to be careful next time or else she would do worse.
