Mistress Helga did not like how snobbish her boyfriend was. She felt it was time he had to change that behavior and since he had not done it himself, she had to help him change. She did this by forcing him to lick the soles of her sneakers. They were dirty but she did not care. She wanted him to be degraded so that he found it a steep price to pay to continue being snobbish.
Mistress Gaia had forgotten about her ex. She had moved on but he had not. When he tried to look for her, she told him off but he did not take no for an answer. She did not want him to look for her any longer because she knew he was trouble and a bad influence. So she humiliated him and dominated him using her dirty sneakers and stinky socks.
Mistress Gaia wanted to humiliate this guy. She knew he wanted her and so she flirted with him and she turned him on. They went back to her house where her boyfriend was. She made out with her boyfriend while the guy was made to lick her boyfriend's shoes as they made out. He could do nothing about it and had to suffer the humiliation of being cuckolded. She even made him lick her spit.
