Slide those panties down your legs, kick them away, and lay down on the floor in front of the mirror with your legs spread high in the air. This is the position sluts like you like the best.
With one hand spread open one of your ass cheeks, and with the other, start rubbing your asshole. Feel your hole pucker in anticipation as there is no other part of your body that is so sensitive as your most private hole.
Keep rubbing your ass sensually, thinking about how badly you need that hole filled. Watch yourself playing with your ass in the mirror. Are you not embarrassed that you are laying on the floor naked and playing with your asshole. Are you ashamed, or are your turned on by watching you do something that most people would find totally degrading?
