Mistress Nikky wanted to show her friend how to punish and torture a slave or a loser. And since there was no slave or loser to demonstrate on, she had to do it on her slave. She wiggled her ass in jeans on her friend's face and enjoyed as she protested in pain. She also spanked her friend and told her she did not want to do more since she was not a loser or a slave. But she had gotten the gist of it.
