This guy thought he was funny and he tried to make fun of lady Rockabella. She did not find him funny and she did not appreciate his jokes. So she punished him for it after she told him to stop it but he went on doing it. She used her sneakers to trample him and he cried and begged her to stop and told her that he had learned his lesson.
Lady Rockabella wanted to show this loser that he was not the kind of person he was used to dealing with. And that is why she chose to use her stinky feet to dominate and humiliate him. He was made to lick her sweaty feet and stockings as well as stinky socks. He regretted what he had done and changed into what she wanted and what she would be comfortable about doing it.
Lady Rockabella had an issue with her ex and since he did not want to accept that he was wrong and to change so that there was no beef, it meant that she had to come up with a way to dominate as well as humiliate him and she did it with her high heels that she made sure he licked. The mistress also trampled him with her high heels.
