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.
