Mistress Jardena did not want to deal with someone who was always discouraging her when she was doing something. She was so pissed at this guy for doing that and she knew that she had to dominate as well as humiliate him and she did so. It turned out to be cruel but she did not have a choice. The mistress managed to make him learn not to discourage others.
Mistress Jardena was interested in torturing this guy and she did it with her asshole. He had to lick it and smell it. So he smelled it first and when he was done, she forced him to lick it. She loved how he did it and she even had an orgasm as he did and that is what made her forgive him because he had pleased her with his licking skills.
