Give her a choice

"Well the way I see it, you have two options. You can either continue wearing what you have on now or change into some of the lingerie we bought earlier."

Tracy takes a moment to consider her options. She looks down at the hole in her crotch, inspecting the damages. The tear isn't too wide and from the back doesn't expose too much of her ass cheeks. The walk back to the car wasn't too long either, however this was a busy street, although it was hardly at it's peak this time of day. Tracy finally arrives at a decision.

"I'll keep these on I guess." You're unsure as to the reason for this decision as you're uncertain which option was more revealing. Perhaps it was in the interest of time, or maybe she liked the idea of her holes being on display to any onlookers, but for whatever reason, Tracy's mind was set.

With Tracy's decision made, the shopkeeper interrupts your grin by looking at you as if you've forgotten something.

"Oh right, payment."

You grab out your wallet and move to the other side of the counter to pay for your new goods. Tracy eyeballs them one by one with excitement as the shopkeeper places them in a bag. He takes extra care to grab your ball gag from before by the straps so as not to touch the drool covered gag. You pay for your goods and flip his sign round for him before exiting the store and beginning the walk to the car.

At first Tracy is nervously looking around at each passerby, watching as they notice her ragged appearance and then turn their eyes south to her exposed pussy. She eventually realises that the exchange is much easier without eye contact, and looks at the ground in front of her instead, somewhat shamefully. Thankfully the walk to the car is fairly short and without incident. You place your bags in the boot before getting into your seats. Before starting the drive home you look at your little slut and take a moment to admire her appearance. Her cunt is out in the open and in contact with the car seat, dried pussy juices staining her yoga pants. You look up at her face and spot saliva and potentially a bit of cum on the sides of her mouth and going down to her chin.

"You have a little something..." You say, touching your chin with your finger. Tracy uses her finger to scoop a little bit of spit/cum from her chin onto her tongue. Good enough, she can get the rest later, you think as you start the car and begin the trip home.
