Goddess Tempest wanted to show this guy that he had to learn to pay his debts with the same enthusiasm he took them. So she asked him for her money but he found a way to lie to her and evade the whole issue. She was not going to take it anymore and so she used her shit to dominate him and to make him do things her way. He had no choice but to do so.
This mistress wanted to punish her slave for bringing girls to her house when she was away. She had come back unexpectedly one day and found him entertaining the girls at her expense. She did not talk. She wanted her actions to talk for her. After she had chased away the girls, she used her slave as her human toilet. She made him eat her shit before she let him go.
