Mistress Ava and her friend lady Bellatrix were duped by this guy and for that, he had to be punished. The mistresses did it cruelly and made sure that he was in pain and that he was humiliated enough for him never to do what he had done. He cried but his tears were not enough to make them stop. Instead, they continued with their punishment as well as humiliation.
Mistress Ava Black did not like how this guy tried to trick her. She was pissed at him and she resorted to punishing him to make him understand that there were things he could not do to her. He had to learn his lesson the hard way and the mistress made sure that was the case. The mistress choked him and also slapped the shit out of him to make this happen.
When dealing with slaves, mistress Ava Black likes to test their pain threshold. That way she knows what their limits are and she is able to better customize her punishments. Today the mistress tied up her slave and she slapped him as hard as she could. She knew he would not resist whatever she was doing to him as he was helpless. She beat him up and was impressed with how he held on.
