Goddess Tempest wanted to dominate this guy and she did it with her shitting fetish. She had chosen to play with herself while she dominated him. That is why she rubbed her clit and she had fun shitting on him thereafter. He was excited as she did it and he thought she would want to fuck him but she did not. Instead, he had to eat her shit and lick her asshole clean.
This mistress wanted to disgust her slave on many levels. She had never done it before so she knew it was bound to be effective. She tied him to a chair and she shit on a paper towel on the ground. Her shit was stinking and it got to her slave. It was disgusting and humiliating to be made to watch that. But that was not all. She also made him eat it and smeared it on his face.
When it comes to cruelty, it doesn't get worse than this. This mistress had a score to settle with this bitch and she did it in cruel fashion. She tied her up with her hands hoisted high behind her back. She whipped her without caring what she felt and had her kneel and bend over as she did it. She then shit in front of her and made her eat it.
