Madam Tulpan was angered by the behavior of her slave and she had to put an end to his nonsense. She did so using her shit as well as her spit. So she had him lie down and she turned him into her human toilet. The slave was fed poo and when he was done eating it, she spat into his mouth and he had to swallow it as well.
Goddess Andova does not care about being respected. She would rather be feared. She knows that she can get people to do anything for her when they fear her and that is why she had to make this loser fear her since she had strategic interests where he could help. The mistress used her poo to strike fear in him and to get him to be malleable enough for her.
