Goddess Nastya, while smoking, used a funnel to direct her watery shit into this slave's mouth. She did not want it to splash all over his face and she felt that he needed to thank her for that. She was being kind and considerate and she needed to be applauded for it. The poor guy had no choice but to eat all the shit that she wanted him to eat.
Goddess Nastya needed to dominate this loser and she used her shit to do it. The mistress teased the guy and she had him where she wanted him. She had him lie down and she blind folded him. Thereafter, she spat on his face and she showed how disgusted she was with him. In addition, she shit on him and made sure that he learned never to mess with her again.
Goddess Nastya needed to shit on this guy and she did it because the guy was wild and she did not want to continue with that nonsense. The mistress felt that the best thing to do to him was to use her shit fetish to humiliate him and she did it after she had used her big tits to tease him. He took the bait and she had fun at his expense.
Goddess Nastya found this guy to be unreliable and she had to do whatever was in her power to dominate and torture him. That is why she did what she did. It was cruel and humiliating for him but he had no choice but to do it. The mistress tied him up and she went ahead to make him a human toilet and he had to eat her poop and drink pee.
Goddess Nastya likes to get her way and she felt that if she used her shit on this guy, she would easily get her way. So she did not bother thinking twice about it and she went ahead to dominate as well as degrade him. He cried but by the end of it, he had no option but to eat the poo. She then let him clean up after himself.
