Mistress Gaia and her friend needed to deal with the boredom they found themselves in. They did not have anything better to do so they came up with some play involving feet and they tried it as mistress Gaia had seen it somewhere and wanted them to try it. They recorded themselves as they did it and reviewed the footage then tried it again. It helped them to pass time.
Mistress Gaia was not going to let this guy get away with abusing her. He had called her names and tried to soil her good name. She depended on her good name to make money in her trade and she had to guard it jealously. She laid a trap for the loser and when she caught him, he had to lick her feet and endure being trampled and humiliated cruelly. She even had him lick the soles of her sandals.
Mistress Gaia is the kind of person who does not take it kindly when she is taken for a ride. Today she wanted to choke this guy and humiliate him for not doing what they had agreed on. She realized that the guy took her for granted and she used her foot fetish to teach him a lesson. She turned him into her sole licker and he licked her dirty soles and endured trampling as punishment.
