Mistress Nica did not care that this slave was naked. She had caught him doing some bad things and she was not in the mood to forgive. Together with her friend, the two of them ball crushed the guy and they also trampled him painfully. That is how he learned never to take anything for granted and to always do the right thing whether he was alone or he had company.
Mistress Nica loves to torture without being interrupted. And that is why she wrapped up this guy so that he would not interrupt what she wanted to do to him. She then took out his dick and she played with it before she tortured it for her own fun. The mistress laughed at the guy and he cried as the pain got to him. But he was powerless against her.
