Goddess Kiffa had an issue with her slave because he had chosen to give her the silent treatment. She did not like it and so she punished him for it. The mistress cruelly made him realize that the silent treatment was not the best way for him to solve his issues. That is why the mistress foot gagged him with her bare feet and ensured that he felt a lot of pain.
Goddess Kiffa knew this guy was behind her betrayal and she did not need him to say anything as he would only lie to her which would further infuriate her. So she used her foot gagging to torture him. She choked him first and after that she foot gagged him. The guy wished he had never messed with her as he was now suffering and it was all self inflicted.
Goddess Kiffa liked this slave but he was too forgetful. That was the only beef she had with him. And since he did not change despite her trying to encourage him to change, she felt it was important to try something different. So she used her foot gagging fetish to dominate him and after he felt a little humiliation, he learned his lesson and he changed and stopped being forgetful.
Goddess Kiffa wanted her neighbor to learn to be civil and know that his actions especially his noisy music, parties and sex disrupted other people's lives. So she took one for the team and she tried to do something about it. She went to his house and he thought she wanted to seduce him and have sex with him but he was shocked when she trampled him and foot gagged him to make him realize his noise would not be tolerated anymore.
Goddess Kiffa does not like people who are messy and when she realized that her new assistant was messy, she had to punish him and make him stop being messy. She knew she had to give him the motivation not to be messy and this came in the form of being trampled and foot gagged. As he nearly choked, he realized it was easy not to be messy than to be punished.
Goddess Kiffa wanted this slave to learn that she was not the sort of person to be pissed off and keep quiet. So the mistress chose to foot gag him and force him to feel pain he never knew she could make him feel. He regretted what he had done and learned that if he did not want to feel such pain again, he had to do things her way.
Goddess Kiffa asked this loser to give her answers but he refused. He thought that the goddess was helpless and would not make him give her the answers. He even tried to shake her down but he was shocked when she turned on him and she forced him to lick her dirty feet and to endure her trampling. He realized she was not messing around and he gave her the answers she wanted.
