Mistress BlackDiamoond did not just fist this guy painfully, she double fisted him. She used both hands to do it and the slave felt like dying. he was in so much pain he could equate it to labor pains. He cried and told the mistress he had learned his lesson but she did not listen to him. She had to finish what she had started and that was her top priority.
Mistress BlackDiamoond found the guy who had carjacked her and she had to teach him a lesson that would serve him for the rest of his life. He did not know her well but she knew him. So she lured him to her torture chambers and she cruelly fisted him in the ass. She made sure to do it without any lube so that it would be even more painful for him.
