Lady Stefanie did not want this girl to continue being a pickpocket. So she used her hard trampling fetish to punish her and make her regret what she had done and promise her that she would never do it again. The pain got to her as she hard trampled her hands using heels and the girl cried and begged for mercy. The mistress told her that if she did it again and was caught, she would only have herself to blame for what would happen to her.
Lady Stefanie wanted to send this guy to enemy territory but she was afraid of how he would fare there. She had to humiliate and torture him so that he learned how to cope in enemy territory. She crushed his balls with her high heels and she did other cruel things to him to prepare him for any eventuality when she finally sent him and it helped him ultimately when he went.
