This guy was careless and his mouth did not help him at all. That is why these mistresses had to ensure that he learned to know where to go and what to do. They had given him a last chance and they had to make sure that he learned to do the right thing. He did but it was after he was forced to lick saliva and enjoy his snot and phlegm.
This mistress knew without a doubt that this guy was behind what had happened. But she wanted to know how he did it and that is why she tied him up and she cruelly ballbusted him. The mistress knew that if he felt a little pain he would talk. And that is exactly what happened as the guy talked immediately he felt a little pain from what she did to him.
