Mistress Gaia had beef with her landlord and she had to sort it out as quickly as she could. That is why she opted to cruelly force the guy to eat her shit so that he would learn that she was not the kind of person to be messed with and to let it go. She did not care that the house was hers. She ensured that he learned his lesson the cruel way.
Mistress Gaia did not want this guy to think that he could do anything he wanted and get away with it. That is why she chose to make him lick her feet, then graduate to eating her shit. He first had to eat it from her asshole before he licked it from the floor. He was degraded but she did not care about what he felt. She was more concerned with the punishment.
Mistress Gaia was shocked at the way in which this guy embarrassed her. She could not believe it and she had to wait until it was just the two of them for her to punish him. She did it in a way he never expected by forcing him to lick the soles of her boots. He was humiliated but that was not all as she also cruelly trampled him for good measure.
Mistress Gaia sat down and thought about what to do to this loser. She felt that it had to be something humiliating for him to learn from it. That is why she chose to cruelly use her shoes to do it. He was forced to lick the dirty soles and was powerless against her. He had to do all she asked him to do and that is how he licked dirty soles.
Mistress Gaia needed to turn her shit into food and she did that to humiliate this loser. The mistress wanted to do it as a warning that his days of doing whatever he wanted were numbered and that he had to learn his lesson the hard way. The guy was shocked but he had to eat it to avoid being punished by the mistress. He learned his lesson the hard way.
