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.
