This guy was rude to the wrong mistress. He had done it intentionally because he looked down on mistress Enola. But he was shocked when she turned on him and she humiliated him using her saliva. The mistress knew that she was not going to sit back and watch someone disrespect her that way and that is why she chose to degrade and humiliate him as she felt he deserved it.
Mistress Enola wanted her husband to be scared of her. That way, he would always do things that she wanted and he would be careful not to piss her off or to disappoint her. She knew that if he coupled love for her and fear of her, they would live a happy life. So she got feared by spitting on him and making him lick her saliva while promising some unspecified consequences if he did not. But she also made sure she fucked him like a pornstar to dilute the effects.
Mistress Enola trampled this guy's mouth so that he understood that she was not afraid of inflicting pain on him. He had to understand that she was the sort of person he should never piss off. And after that, she asked him to lick her saliva and he obediently opened his mouth and she spat into it. It was a test and he had passed with flying colors. She let him go.
