Goddess Nastya had taken her car for repairs at this guy's auto shop but things did not work out the way she wanted them to. That is why she had to dominate and she had to torture him for him to get the point she was passing across. The point was that her car had to be fixed in time and correctly unlike what he had just done to her car.
This guy was condescending and goddess Nastya was not going to allow it. She had to do something about it and she chose to use her shit to punish him. He did not see it coming and he was shocked. He could not believe that he was being turned into a human toilet by the mistress. He could not do anything about it and had to endure all that she did to him.
