If there were some things that this mistress wanted more than anything else were answers. She wanted them from this guy but the guy did not want to give them to her. She had to come up with a way to torture him and get them and that is why she chose to cruelly trample the shit out of him. He learned his lesson the hard way as she used her high heels to do it.
This slave had never been punished before and he felt that he could do what he wanted and get away with it. But that was not the case and the mistress did not like it. She used her heels to trample his nuts and he cried as he had never felt such pain before. The mistress warned him that if he ever did that again, he would have himself to blame.
