When this mistress noticed that she was dealing with a guy who did not do things the way she had asked him to, she knew it was time for her to punish him. And it had to be in a way he would never forget. That is why she used her fisting fetish to do it. The pain he felt was out of this world and it helped him learn his lesson.
Mistress BlackDiamoond knows how to get what she wants. Today she wanted some money from this loser. She knew he was loaded but he was a miser and did not like to part with his money. So she fisted him in the ass and she even double fisted him to make it even more painful. He cried in pain and when it became unbearable, he gave her the money she wanted.
