Mistress Michelle wanted this guy to learn that messing with her was a ticket to untold pain and suffering. So she took out a huge strapon and she used it to fuck him in the ass. She wanted to fist him in the ass but she chose not to do it because she did not want his poo on her hand. She knew the strapon would work just the same.
Mistress BlackDiamoond was angry that this guy had betrayed him. She was not going to forgive him. She had to teach him a lesson and make him an example to others. So she fisted him in the ass cruelly and painfully. He was in a lot of pain but she did not care. That was actually her intention. She nearly inserted her whole arm into his ass and she made him regret what he had done.
Mistress Kira did not appreciate the fact that this loser was not doing things her way. She had to punish him and she did it cruelly. She did not want to ever punish him again so she had to make sure this time she punished him would be enough even for the future. She fisted him painfully and she did not even use lube. The pain of it all taught him a lesson he will never forget.
