Mistress Cybill knows that her slave is desperate to worship her ass, but she wants to make her pet earn the privilege first. Cybill orders him to worship her boots with his tongue, then allows him to worship her ass with a few kisses. But the slave does not kiss her ass to her satisfaction, so Cybill decides to really make him worship her ass by sitting on his face. Cybill enjoys making the slave suffer under her ass, ignoring his pathetic begging until she decides that he does not deserve to worship her ass anymore. Instead, Cybill crushes the face of her useless pet under her boot, then leads him away to lock him back in the kennel.
