Take a good look at my ass, mister smarty pants.
But, keep your hands to yourself (you've obviously noticed that I haven't completely immobilized you . . . yet.)
I'm thinking that you're going to guess right, which will really make your girlfriend happy, but will sorely disappoint me.
So, get your thinking cap on.
What's that?
Oh, yes, I forgot . . . you can spot a shemale a mile off, but you still have to see my breasts before you make a guess. Sure, you're real perspicacious. Harumph!
Well, O.K.
