With her top, of course ;)

You silently get close to her as she faces away from you.

Putting your phone away to free up both hands, you wait for the right moment. Katie has almost got the top arranged when you strike. You grab the bottom of the top and bring it up turning it inside out. Her breasts pop out the bottom of the top, but you keep going higher, forcing her arms and head inside the top. You notice a hair tie (scrunchy) on her wrist and snag it. Her protests are muffled as you secure the material with the hair tie, trapping her hands inside with her head. Her breasts are once again hanging free inside the lace bra-let and there is nothing Katie can do about it now.

"Hush Katie I am just enjoying the show. If you are not providing a show, I need to help you out, right?"

If you listen carefully to her inside the top and can make out what she is saying. "Let me out, this isn't funny!"

You can just about see her Pink thong inside her leggings, but it would be much clearer if they were stretched tighter over her ass.

You find the place where her ear should be and whisper "Bend over and stay there until say. If you do this, I will let you out and you can leave with all your clothes."
