Tiffany Takes Her Turn

Without warning, Tiffany began to remove her shirt. The few people still near the area weren't noticing yet, but there was enough that Samantha immediately worried for her sister's safety.

"Tiffany, no, you can't! People will see!"

Tiffany at this point didn't care. She wasn't an exhibitionist, she didn't really feel the passion flow when naked, but she did feel a desire to accomplish her goals, and she needed to make sure this goal came together. If it meant being seen by random bystanders, she'd do it.

"It's not a big deal, sister. It's just nudity. We should treat it as normal as wearing clothes." Samantha didn't seem to buy it, so Tiffany knew she had to continue, and began removing her belt. Tiffany removed that easily enough, but lowering the pants did cause her to feel something. She knew the feeling well, it came from her fantasies. This wasn't a fantasy she ever had though.

'It must be because how close I am to victory.' Tiffany's rationalization may not have been the most solid, but it made the most sense to her. Within seconds, her pants were lowered, and as she removed her shoes, socks, and pants, all in one go, she finally realized this may backfire on her.

Projecting confidence, she looked to her sister. "See? This isn't so bad." She waltzed around a bit, now definitely getting some attention from various passersby. She didn't require any attention, nor did she want it. This was all to push her agenda on Samantha, to manipulate her into believing it was good to be naked. Was Tiffany a bit embarrassed? Sure. But if she succeeded, her sister would be her petgirl, and that was an embarrassment she'd enjoy for a long time...

Tiffany, as one last showing of confidence, intended to lean on the automated carrier and make a gesture as if to say 'After you,' but the machine lambasted her.

"Error!" This made Tiffany jump, but worse than that, it ruined the zone of confidence she had easily slid into. She quickly masked her fear again, but the damage would be done.

"Task incomplete! Pet carriers are only for pets. All other possessions must be stored in luggage or carry-on."

'So this is what Samantha meant,' Tiffany thought to herself. The AI and its camera reading system really was that poorly programmed. 'It's one thing to not tell me or Samantha apart, but to not recognize species?'

Tiffany shrugged it off. "Whelp, at least we know the machine is determined." Tiffany then focused on Samantha, hoping to pull off a soft but intimidating look. "You can do, Samantha. You should do this."

"Easy for you to say," Samantha retorted. "You've still got clothes. This thing would want me naked, and..."

"And?" Tiffany had an idea on what Samantha was about to say, but she wanted...needed, to hear it.

"And...I'm not as strong as you, or attractive, or even as educated. You've got all those programming certifications, you've got a strong will and spirit, and, as for looks..." Tiffany made a motion to encourage Samantha to continue. "Well, with the shimmering hair, your perfect curves, your...ahem...large breasts, I'm just...not as sexy as you."

That was the key. Tiffany's heart accelerated as Samantha's face became flush. This was just an unintentional tease of what could be coming soon in Cancun. 'Yes...a lot of things would be coming in Cancun.' Tiffany thoughts led her astray, thinking of all sorts of possibilities of where this vacation could bring her, and Samantha.

Samantha waved her hand in front of Tiffany's face, and instinctively Tiffany grabbed her wrist and squeezed. "Ow!"

Tiffany, back in reality, let go, worried to ruin the opportunity. "Sorry, I just got lost in imagining...all the things coming." She gulped instinctively, and internally cursed herself for showing the weakness. She tried to play it off. "Look sis, we're holding up the plane. Getting naked is easy, watch."

And with that, as fast and casually as she could, Tiffany removed her bra and panties. It wasn't exactly a sexy striptease, but that was the point. She needed to sell to Samantha that this kind of casualness was okay.

"There! Now I'm naked, showing my support for all the nudists out there. They'd be really happy to see both of us spreading the good view." Tiffany winked, hoping to add some levity. It worked, as even though Samantha blushed, she smiled too. Tiffany was now sure that this plan was going to work. "Now, if you get naked next, we can get you in the cage and get to our vacation! And don't worry, everyone will love and appreciate you for all this!"

'That was a little ****,' Tiffany admitted, 'but I need to get this going before we get kicked off the flight.'

"Okay, I...guess I could see myself...being brave like you. But," Samantha gulped, and instinctively covered herself, despite wearing clothes. "It's one thing to be naked. But what you're asking...getting naked, crawling into a cage, there's no way I could do that."

Samantha seemed pretty hardline on this point, and it may have been enough to convince most people to believe her...but Tiffany saw something different. The way Samantha's face summoned its blush, the posturing she was doing, and most of all, the tongue. Tiffany could have sworn Samantha tried to lick her lips. It was an action she knew some people did subconsciously when encountering a very pleasurable situation. It was an action she was guilty of, and she was pretty she had seen Samantha do it plenty of times in the past.

It was possible that Tiffany's desires for Samantha to love her kink was real, or just that was a nervous tick Samantha had that Tiffany didn't know about. It could even be Tiffany's mind playing tricks on her, and that there was no lip licking tongue at all, that Tiffany's subconscious just made it up.

'It doesn't matter. All that matters is getting what I want.'

"Don't worry Samantha, I can prove it'll be fine, watch." And with that, Tiffany went onto her hands and knees, and began to crawl backwards to the cage. Or rather, she tried to. The automated cage actually rolled back, shouting, "Error! Pet not wearing control collar."

"What?" said both girls in unison.

"Flight Service Inc. mandates all pets wear control collar for their safety and the safety of others."

Tiffany kneeled up, angry, but was surprised when it was Samantha who yelled at the machine. "That's ridiculous! She doesn't need a collar!" Tiffany was charmed that her sister actually stood up for her; it was never required before, but it was actually nice that Samantha could do so when the time arose.

"Incorrect. Flight Service Inc. mandates all pets wear control collar for their safety and the safety of others. If pet will not wear collar, security will be authorized to detain pet and owner before alerting authorities."

"Unbelievable," Samantha said. She reached out her hand to Tiffany. "Come on sis, let's get a refund and get out of here." A normal sister would gladly take her hand, and appreciate the protective nature of a sibling like Samantha.

"No." Tiffany casually pushed her hand away. "We worked too hard for this vacation. And I'll prove to you that putting up with all of this frustration will be worth it." After stripping herself in a public place, Tiffany had to prove this to herself as well. She turned to the machine. "Give me the collar."

"You will find a control collar in the compartment above the pet carrier which can be rented for a small fee."

"Ugh!" Tiffany growled in frustration. "Fine, pay for the collar."

"Oh, uh, right." Samantha dug into her pocket and pulled out a ten dollar bill she had saved for emergencies.

Tiffany wanted to growl at how slow her sister was to react, but Tiffany quickly realized it would make her look like a rapid pet. 'And I'm not a pet.'

A click occurred, and Tiffany looked over. Samantha had paid the automated carrier, and in turn it dispensed a collar.

"Uh, sis, should I?"

Tiffany growled, "No, I'll do it myself." Strangely, a part of Tiffany wanted Samantha to do it, but Tiffany shoved that thinking aside. She had spent too long wanting to dominate and manipulate her sister. Giving Samantha any more authority over her now would be going too far.

The collar easily snapped around Tiffany's neck, concluding with a beep. She crawled backwards into the carrier. She looked to her sister, a look of satisfaction on her face. "See? Easy! Now it's your-"

The carrier locked up.

"Thank you for using Flight Services to transport your pet. You will find them at your destination."

Horror struck the sisters as they realized what just happened. Tiffany began to swear like crazy, and struggled violently against the door and walls of the carrier; the carrier didn't budge. Samantha, stunned that Tiffany had just gotten pulled into the role Flight Services Inc. tried to screw into her, tried to jump for the automated carrier and pull open the door; it was too late, as the carrier was already off.

As it drove away, Samantha was more worried than ever. Not just did she worry about her sister going on a naked adventure...she worried that something else might be wrong with her. Tiffany was never so angry and aggressive before...at least, not as far as she could recall. Samantha thought about trying to help free her sister, but she herself said she wanted this vacation, and she was **** to get them both to go. And with the plane delayed for so long, if she didn't leave now, the plane would probably cancel their tickets. For now, Tiffany would have to be the pet.

Samantha turned to the security robot. "Uh...so. I'm not a pet. Can I have my sister's seat?"
