Princess Nikki needed her new slave to eat her poo and she made sure that he did. The mistress wanted him to eat her poo so that he would learn never to take anything for granted. She was afraid that he would learn to disobey her so that fear made her do something cruel and crazy for him to learn to fear her. That way, he would never disobey her.
Princess Nikki was amazed at how this loser was able to lie with a straight face. She had never met such a guy. He even believed his own lie. Even when caught, he still tried to lie his way through it. She knew she had to do something crazy to get him to stop lying. She forced him to eat her shit. The guy had a hard time eating her poo.
