Goddess Gabriella did not want this guy to continue being difficult. He was difficult to deal with and she felt that the best way to deal with him was to humiliate him which she did without caring. He was shocked at what she did to him as she cruelly spat on him and used him as her human ashtray. He never saw it coming but he knew he was done being difficult with her.
Mistress Gabriella felt that her slave was starting to misbehave and she did not like that. She felt that he had to change and it was up to her to make him change. So she forced him to change by cruelly having him lick her spit and also lick her feet. Her feet were sweaty and so he had to lick her sweat besides her spit. It was humiliating but he deserved it.
Mistress Tatjana needed this guy to lick her spit. She tried to talk to him to do so but he did not do it and she did not want to force him since he had not done anything to warrant that. So she convinced him instead to do it for a fee and the guy agreed. That is how she got him to lick her saliva and also to lick her feet.
