Mistress Kinga felt that she was disrespected by this guy and she had to teach him never to do so again. She used her saliva to do it because she felt that it was not too much. It was not painful but it was humiliating and so it was perfect for what she wanted to do to him as well as the message she wanted to send to him. It worked.
Mistress Jane was disgusted by the things he found her slave doing. She did not know he was a pervert and she was disgusted when she learned that he was. She tied a rope around his neck and she used it as a leash. She also spat on his face and on the floor then asked him to lick them. He was degraded and it served as a warning to him.
