Mistress BlackDiamoond needed to help her friend teach her husband a lesson and they chose to do it with spit. The two of them ganged up on the guy and they tied him up after they had undressed him. He was then spat on and made to do some humiliating things. He had no choice but to do all of those things and he learned never to mess with his wife.
This guy was interested in this girl and she had milked his desire for her and when she did not have any more excuses, she knew that she had to find a way to turn him off so she used her drool to do it. She had learned that he found other people's spit gross so she did it after lying to him that they would have fun that day and he was turned off and did not want anything to do with her again.
Lady Bertie does not like anyone giving her the silent treatment. She is the only one allowed to give it to others. When her slave gave her the silent treatment, she was pissed and instead of finding out what the problem is, she punished him for it. She made him lick and swallow her spit. She spat on his face repeatedly and he had no choice but to lick it.
