Lady Dalin wanted to ballbust this guy and she did it with her high heels. She had to make sure that the guy felt not just pain, but that he learned his lesson. That is why she had to do whatever she needed to do and she had to see to it that he stopped that habit. The guy did not want to stop it but he was forced to do it.
This mistress did not have much time to get the info she wanted from this guy. He had refused to cooperate and she had to use other means to get the info. So she settled on using her high heels as well as kinky trampling to do it. The guy was shocked at what the mistress did and as the pain got more and more intense, he spilled the beans.
