Goddess Nika had an asshole for a landlord but she did not want to move out as she knew others would come in after her and would suffer the same fate. She wanted to make things better for those who will come in later and so she used her extreme humiliation fetish to deal with him. She made sure she had fulfilled all her obligations to him then she teased him, turned him on and used her spit to humiliate him after denying him and leaving him high and dry. She then told him all the nonsense he did and why he had to drop it.
Goddess Nika wanted this perverted slave to learn a lesson and that is why she baited him. She was dressed in a sexy way so as to get him out of his shell. He took the bait and she had a great time torturing him. And she made sure it was the sort of punishment he had never had before. It was extreme humiliation and he learned a lesson out of it.
