I need to know if my slave is better at licking pussy or asshole. It's important that it's on record so the slave can't try to make stupid excuses to get privileges he doesn't deserve. So, he is going to pleasure my asshole with his tongue, then I'm going to let him worship my pussy. Whichever activity is more enjoyable for me is going to be the permanent job for the slave. Starting with asshole, he tries hard to please me and licks the stinky hole diligently. I am impressed - I am considering deciding his job for him right here and now! He seems to have an affinity for ass cleaning. Scraping up the sweat and filth with his tongue seems suitable for him. I moan with pleasure. Then it's time for pussy. I sit on his chest with all my weight and stuff his mouth full of my juicy pussy lips as he whirls his tongue around desperately aiming to please me. He doesn't want to end up being an asshole slave. But his pussy licking skills are not up to scratch. I try to enjoy myself but ultimately end up unsatisfied. As I expected, he will be banned from pussy licking and will be a permanent ass licking slave from now on. I spread my cheeks to swallow his face and order him to stick his tongue back in my asshole. He is devastated. But it's really only fair!
