Hello slave, do you like my ass? I think you should worship it then. On your knees, and crawl to me, give each cheek 25-50 worship kisses. No quickies! If I feel you held back whatsoever, I will force you the hard way. Ooh, stop smiling, you won't enjoy it. Now stroke 200-1000 times (any speed) to show my ass the respect it deserves. I think I should sexually strip and tease you whilst you do these.
Trust me, if you think this is hard, then give up! I haven't even started!
