Mistress Nicole and her friend mistress Kira felt that the best thing to do to this girl was to trample as well as humiliate her and they did it without thinking twice about it. The girl was shocked at how they stuck their boots in her mouth and nearly tore it apart. But she had to feel the pain and she felt it before the mistresses felt it was enough.
This slave had the mistaken belief that she was an equal to mistress Anna. She had tried to tolerate her thinking that she would change her ways and her views but it did not happen. So she had to teach her a lesson and she did it in a cruel manner. She used her dirty boots to humiliate her. She had to lick them and that made her learn her lesson.
