We have some shopping to do

"Now, come on," Roxy purred, taking Sarah's hand in hers and leading her away from Alexia. "We have some shopping to do."

Sarah's heart raced as she was pulled along behind Roxy, her mind racing to keep up with the older girl's erratic pace. They turned a corner and came to a pet store, the smell of fresh hay and animal fur wafting out to greet them.

"We're going to need a leash and collar for both of you," Roxy announced, pushing open the door to the store.

Sarah's heart sank as she realized what Roxy was implying. She glanced over at Alexia, who was looking away, her face flushed with embarrassment.

Roxy led them to the pet section of the store, where she picked up a small dog leash and a pair of cat collars. "These should do," she said, holding them up for Sarah to see.

Sarah swallowed hard, her throat dry. "But... we're not animals," she protested weakly.

Roxy rolled her eyes, her expression one of annoyance. "You're right," she snapped. "You're not animals. You're my captives, and I want you to cosplay as such."

She held up two black leashes and collars, one in each hand. "Put these on," she ordered, handing them each a pair.

Alexia and Sarah looked at each other, their eyes wide with fear and confusion. They both knew that they had **** but to obey Roxy's commands.

With trembling fingers, Sarah reached up to fasten the collar around her neck, but she managed to secure it in place. She looked over at Alexia, who was doing the same thing.

They both stood there, feeling the weight of the collars around their necks, their hearts racing as they tried to process what was happening.

Roxy led them to the checkout counter, where she paid for the leashes and collars. The cashier, a young man with hair tied up in a messy bun, looked at them curiously as she rang up the items. "What are these for?" she asked, raising an eyebrow.

Roxy smirked, her gloved fingers brushing against the leash in her hand. "Oh, they cosplay as my captives," she replied nonchalantly. "At the convention."

The cashier, raised an eyebrow. "Oh, really? That's quite a unique costume."

"Yup," Roxy said, tucking the leashes into her bag. "They're cosplaying as my prisoners at Bowser's castle. I'm Bowsette, and they're Princess Peach and Princess Rosalina."

The cashier nodded, his eyes flicking between the two girls. "Ah, I see. Well, have a fun time at the convention!"

Roxy smirked, her gaze fixed on Sarah's neck where the collar was fastened. "Oh, we will," she replied, her voice dripping with sarcasm. "And if my captives decide to show off the bodies, I don't have to pay for it, right?"

The cashier blinked, surprised by Roxy’s candor. "Uh, well, I guess I can pay for it if they do. But I'm sure they don't want to."

Roxy's smirk widened as she turned to Alexia and Sarah, her fingers tightening around the leashes. "You heard him," she purred, giving the straps a sharp tug. "Time to earn your keep."

Alexia's heart raced as she looked at Roxy, her eyes wide with fear and confusion. She knew what she had to do, but she didn't want to do it. She took a deep breath and slowly began to unbutton her dress, her fingers trembling as she worked the tiny buttons loose.

As she opened the back of her dress, she pulled it down to reveal her breasts, which a perky. Her nipples were already hard from the cold air conditioning in the store. She then lifted the bottom of the dress, exposing her pussy, which was shaved clean and glistening with anticipation.

Sarah did the same, pulling down her strapless dress as she showed her breasts then lifting up the bottom of the dress to show her pussy. Her heart raced as she felt the weight of the collar around her neck, the leash in Roxy's hand. She looked over at Alexia, who was also exposed, their eyes meeting for a brief moment before they both looked away, embarrassed.

As they stood there, exposed and humiliated, the cashier couldn't help but stare at them. He had never seen anything like this before. He cleared his throat and spoke up, his voice breaking the tense silence. "Um, Roxy? Can I take a picture of them?"

Roxy smirked, her eyes glinting with mischief. "Sure, go ahead."

The cashier quickly pulled out his phone and snapped a few photos of the two girls, their bodies on display for his perverted gaze. He couldn't help but feel a twinge of arousal as he looked at their exposed forms.
