Remove it for her

Making the most of Katie's helpless state, you run your finger over her wet thong, her body trying to follow your fingers as you pull them away from the mound hiding her pussy. You take hold of the material and pull the thong down her legs. Her pussy is revealed in the strong store lighting, glistening with arousal. Her thong is small and cheap, probably to help make her feel more slutty during her teasing trips. You pull it hard and it rips off her body. You take the bra-let from the floor and place both items behind some items on a nearby shelf. A nice surprise for some male shopper with any luck.

Katie is bending over in the store, her pussy and breasts out for any passerby to see. You chuckle to yourself at the comic yet erotic scene before you. Katie can't help but moan, waving her ass and pussy at you from her pose. You reach out and push one finger into her dripping pussy, causing the loudest moan so far. She thrusts back at you trying to get your finger deeper into her pussy.

"Look how desperate you are, you are making a puddle on the floor Katie" you whisper in her ear. She moans in response, seeming having lost the power of speech. "Should I fuck you right now in the store? You might even get an audience".

Katie gasps and finally managed to say, "No, please not like this.... Let's go somewhere."
