Obviously the most submissive position is on my back. That is where a good Submissive Whore should be to assume position as your toilet. Well, make that on my back with your ass on my face. Truth is that the best way to determine the submissiveness of a slut is how she assumes the position.
Another way to determine if a sub slave is a good one is shown now. Your ass should be the focus of her attention. A good slave will spread your ass cheeks if her hands are free. If she is bound, as is proper, she should start driving that tongue between your ass cheeks and start rimming that hole.
With me, you get a good slave. I will lick and suck that asshole. Clean that brown juicy moistness from inside and rim it like a good slave. Eating that ass and milking that prostate for master’s pleasure pleases me.
