Lady Nightfrozen had beef with this guy because he was full of lies. She did not want him to think that she was powerless and she had to make sure that he knew never to repeat that. So she wore her high heels and she told him to choose whether she would crush his hands or his balls. He chose his hands but she did not do it. She told him it was a warning and a last chance.
Lady Nightfrozen wanted to tame this slave because she felt that he was not as well behaved as she wanted. So she had to make sure that he learned his lesson the hard way. He wished he had not messed with her but it was too late and the mistress used her shoe fetish to punish him. He was trampled and crush and in no time, he had learned his lesson.
