This hot giantess did not want to deal with people who misbehaved and when this guy did, she had to do something about it which she felt would make him avoid doing that. The mistress used her giantess powers to dominate him. He was crushed and turned into a tiny man and she tormented him until he cried and begged her to stop what she was doing to him. But she did not stop.
Mistress Gabriella wanted to humiliate this tiny man and she did it with her feet. She stomped the shit out of the guy and she transformed him into a tiny man. He tried to beg her for mercy but she ignored him and she made sure that he had a great time. He cried but she did not care and instead went on to humiliate him and have fun at his expense.
