Lady Soles does not like bullies. When she caught this guy bullying others, she knew that she had to do unto him what he did to others so that he could get a taste of his own medicine. That is why she chose to dominate as well as to degrade him. She did this with her hot giantess fetish and she made sure he cried and begged her as well as peed on himself as she turned him into a little man.
Lady Soles needed to scare these little men shitless and she did it with her giantess ass and with her shit as well. She had them think that she would cover them with her shit and drown them in it. But she did not do that and was only scaring them. She loved their reaction and knew that they were scared of her and would never do anything to piss her off.
