This guy was too inquisitive to mistress CatDeluxe and she did not like it. She felt that he was too much and so she had to do something about it. That is why she went out of her way to deal with him and make sure that he would stop that habit. The issue was handled by forcing him to lick her feet, her ass as well as her saliva.
Mistress Cat and her friends lady Stefanie and madame Svea wanted to make sure that they got this guy punished for what he had done. They wanted to train him to lick spit as they felt that he would mess again and they wanted to always use spit to degrade him and make him feel humiliated. So the mistresses did what they do best and they degraded him with spit and also trained him.
