Mistress has instructed me that the new cleaner needs to be taught how to clean effectively. She has given me very specific instruction on how to teach you. As you are there, hard, kneeling on all fours for me, I make you beg for me to let you jerk off to me. After sufficient begging I take out my tits and fondle them for you as you jerk it. After you have let go of your load I instruct you how to clean it up, licking it like the little dirty doggy cleaning boy you are.
