Mistress Saida and her friends mistress Kennya and mistress Sanders wanted their boots licked so they did not hesitate to make this guy do it. He had pissed them off and that was a good opportunity to send a message to him that they would not tolerate any nonsense from him. He regretted pissing them off but it was too late and he had to undergo the punishment to its fullest extent.
Mistress Saida wanted to show this bully that he was not all that he thought he was and so she used her boots to dominate and humiliate him. She did it in front of the people he had bullied. In addition, the mistress forced the guy to lick the boots of those he had bullied before. He was degraded and humiliated but at least he learned his lesson and stopped bullying.
