Aaron is starting to get used to his wife's dominating personality, but Mistress Caren still believes that he requires some advanced training. She orders him to worship her beautiful black ass - first with his nose. He smells the sweet scent of her ass and tells his Mistress that he likes it. Mistress Caren then allows him to place his lips on her round ass cheeks, and kiss them softly. When she is pleased with that, she moves on to the most important part of this lesson. She tells him that she would like her ass and asshole thoroughly cleaned by his pathetically small tongue. He sticks it out as far as he can and inserts it into her ass. She spreads her ass wide open so that he can clean every inch of her sexy ass, and besides a few mistakes, she is generally pleased with his cleaning ability. But that is only because it is his first time. If he does not progress in his ability to clean her asshole, he will be sorry.
