Back to the shoe store, panties in tow.

"Back to the shoe store?" You proffer, tapping.

"Sure." I nod, my purse dinging. I step out and toward the escalator, and you follow along stepping on behind me.

"Oh, gosh, my shoe's untied!" I say oh-so-believably as I bend over and being to fuss with my lace-less flip flops. My shirt rides up in back, being a shirt and not a dress, baring my panty-clad ass to the world at large.

Notionally, this is fine. I am wearing panties, after all, and these days this could really pass for a dress. A short dress, but a dress. And it's totally reasonably that I'd need to tie my shoe on the escalator. With my knees locked straight.

Of course, the part where my shirt slips right along my torso, baring most of my back with my ass in the air, my tits all but popping out as well, ya, that part might be a little more... unusual.

An unusual moment later and we reach the bottom. My shirt rights itself when I do, and we step off heading into the shoe store.
