"Trust me, you need a pet"

Tiffany knew she needed full confidence if her plan was to succeed, so despite being naked, sitting like a dog, and being more aroused than she had ever been in her life, she was going to say all she had to say with confidence. "You laid out some good points Samantha, I can respect that. But I laid out even more, and even though you think I'm going to struggle, I know how you can be. Clearly you need me to follow you," Tiffany boasted.

Samantha wasn't sure if she believed the boast, but Tiffany did have a knack for convincing her on things. Usually. "Alright, I guess as long as we be cautious, then we'll try it. But if you feel the need to back out, just tell me, and we can hurry back here." Samantha took some clothes from the basket and went into the bathroom to change.

Yet, as soon as the door was closed, the more cocky Samantha stood in her place, dressed in an outfit Tiffany had once seen Samantha in, a dress that highlighted her body, a costume fitting of a model. Tiffany had seen Samantha come home after a work party in that, and dreamed about it for many nights afterward. "You're really that determined to prove your points about petgirls, huh?"

Tiffany gazed with fervent anger at the doppelganger. "Yes! Now stop haunting my thoughts! I have this all under control."

The fake Samantha couldn't resist giving Tiffany a sly grin. "Even though you're naked and crawling and somehow hornier than before?"

"...Yes." The naked girl hated how much that grin was turning her on. "It's all going to work out. Just... trust me, okay?"

"Ooh, trust you? Such an intimate thing to say to someone you treat so aversely." Samantha knelt down to look Tiffany in the eyes. "Oh, I trust you. But it's the world that makes me wonder." Samantha reached out and pet her sister's head. "But I don't think there's any way I can stop you. You're clearly enjoying this too much."

"I... it's..." Tiffany wanted to choose her words carefully, she wanted to really tell off the doppelganger. "It doesn't matter if I'm enjoying it or not. What matters is making Samantha realize her true role."

The doppelganger started to fade away. "Oh, don't worry, I think she will..."

"What do you mean?" Tiffany asked, but was instead answered with the real Samantha opening the bathroom door.

Samantha gave a confused look. "What did you say?" Samantha asked. She was now wearing a white shirt and short jean shorts. "Sorry, I kind of want to surprise you with the bikini I chose, so you'll have to wait. I hope I didn't take too long."

"N-no... it's fine, never mind. Let's just go," Tiffany said, her mind dealing with the whiplash of switching from the fake to the real Samantha. Samantha leaned down to pick up her leash. Tiffany raised her eyebrows. "What are you doing?"

"Well, you said you're supposed to keep acting like a pet to keep the robots from taking complaints seriously. I just thought..." Samantha said, giving a look that was both confused and yet embarrassed. "Or am I going too far with the idea?"

Tiffany, so caught up in all her attempts at control, and her insane levels of arousal, was having trouble trying to decide that herself. "Well... no." Tiffany admitted, though quickly thought to herself, 'This is all just part of the plan. Part of the plan. Part of the plan...'

Samantha approached the door, and put her hand on the knob, and opened the door. Yet, she paused, waiting to take the first step outside. "You can still back out, you know. At any time. And I won't cast judgment."

For some reason, that kindness, that accepting attitude, it truly burned Tiffany. "You're damn right you won't cast judgment. Because I'm your pet, and there's nothing wrong with being a pet!"

And with that, Tiffany crawled ahead of Samantha, and into the open hallway, completely naked, and more aroused than she'd ever expect to be.

Samantha could not deny she was impressed, and in a way almost inspired. She couldn't ever imagine herself becoming a naked pet, much less enjoying it, but seeing her sister so confidently crawl forward, as if this was the role she was born for, made Samantha feel like she could take on any challenge. She wasn't expecting to be her sister's protector on this trip, and certainly not help her discover her naughtier side. But that just made the trip far more impactful, something that would matter for the both of them for the rest of their lives.

Of course, had Samantha looked a bit more closely, she would notice that it wasn't just courage pushing Tiffany forward. Tiffany's arousal was already growing strong, and she could only keep crawling forward to keep control over it. Every movment she made she gave extra focus on, as she could easily feel her mind demanding attention on her lower body. 'I... will not... give in...'

Tiffany reached the elevator, and Samantha pressed the button. To distract her, Tiffany tried considering her options. 'On the one hand, if I gave in, I would make a mess... and be stuck trying to recover... and feel really, really good... On...on the other hand... w-wait, why shouldn't I?'

Luckily for Tiffany, the elevator arrived, and she was snapped back to reality. 'Focus Tiffany, focus!' Tiffany reminded herself as she crawled inside.

Just as the doors began to close, Tiffany looked where she was sitting before, and noticed a small but dark wet spot. 'Stop it! You're getting too deep into the role! Focus!' Tiffany tried to rationalize that she had, in fact, already cummed once, last night. 'I'm covered, I'm good, I don't need to give myself more attention.'

While Tiffany scrunched her face in frustration, arguing with herself, Samantha just watched curiously. Samantha figured it would be better to let Tiffany figure out her own needs, and thus stayed silent.

That didn't stop Samantha from thinking about the situation. In a weird way, as much as this was beyond anything Samantha considered normal, there was something fun and even enticing about this. Tiffany always had a strange attitude about her, with some more aggressive tendencies she was starting to notice. And yet she was so determined to live in this new lifestyle. It was an odd dichotomy, but there was something fun about it too. 'Tiffany's basically acting like a brat, but she's clearly enjoying this scenario. And weirdly... I think I want to help her enjoy it.'

Finally the elevator landed. Tiffany tensed up, and Samantha finally decided to say something. "Are you okay Tiffany? You seem nervous."

Tiffany jumped at the comment, and gave a dirty look to her. "Yes. That's intentional. Pay attention."

Boldly forward Tiffany crawled, doing everything to ignore her nerves for the sake of her own pride. Samantha just smiled, shook her head, and followed along. The lobby was empty, to Tiffany's internal relief, but the real test would be if the pool area was.

It was not.

Luckily, there was only a few people at the pool, an older man and woman, as well as another woman lounging off on a bench. The man and woman looked to be a couple, late-forties, and were sitting at the poolside bar being served by a robot. They were dressed modestly, swim trunks and an open jacket for the man, a one-piece suit and sarong for the woman. The other woman, a white woman in her early twenties, was in a fairly small bikini, with only sunglasses and some sort of hair-tie as her adornments. Tiffany had no idea what Samantha was going to wear, but Tiffany was quite sure she'd be the most undressed one.

Samantha looked down at Tiffany, curious to what she was thinking. It was hard to tell, Tiffany did seem nervous, but she seemed willing to push through these sort of situations. Samantha figured she should word her next words carefully, in a way to give Tiffany the option to back out, without making an obvious order. "You know, the pool is a little crowded."

"Yeah..." Tiffany said, barely paying attention to her sister's words.

"No one's seen us yet, we could find something else to do if you don't want to go out there."

Tiffany's eyes started to glaze as her fingers craved action. "Go...out."

"Well, if you're sure. I'll open the door for you if you want." Tiffany nodded, still lost in thoughts, or rather, the lack of thoughts. The haze of arousal was clouding Tiffany's ability to truly think. "Just take the next step forward Tiff. We'll be fine, and, well, you'll probably even enjoy it," Samantha said, hoping her words were helping her sister. It did take Tiffany a few moments before she finally crawled forward, but she did so of her own volition.

Since the pool area was so big, eventually Tiffany did stop, unsure what to do next. Deciding to get as much privacy as possible, Samantha tugged lightly on the leash to lead Tiffany to a lounge chair in the corner. There was definitely a chance people could notice them, but they were fairly far out of eyesight. She couldn't be sure if Tiffany pieced that together, but Samantha figured Tiffany wouldn't complain even if she did. Samantha felt an urge to do something, anything, just a sign of touch and approval. So, as soon as they reached the chair, Samantha leaned down and pet Tiffany as she stood on all fours.

The petgirl tensed, but said nothing. Samantha smiled, and set her stuff down. Checking once more to make sure they were unnoticed, Samantha began lifting her shirt, and Tiffany's eyes were locked on to the full act. Tiffany had made plans to tease Samantha about her chest, in a way she believed was in good nature, but even with a small chest, it was enough to entice Tiffany. Samantha didn't seem to notice, but she was quite proud of the bikini she chose. Quite revealing, a dark blue with black spots, the bikini was more revealing than anything Samantha wore before, but with no leering eyes that she was aware of, she felt confident enough to try it.

"So... what do you think?" Samantha blushed as she posed, hands behind her head, eyes shut, imagining herself in one of those classic sunscreen commercials. Though thankfully the cloud coverage removed the sunburn concern.

Tiffany's brain was blanked out, too stunned by the sight. All of Tiffany's plans were on a reversal trend, and any opportunity to turn them around was difficult when Samantha's body came into view. Despite Tiffany never giving praise to that kind of body before, she was mesmerized by the sight. Granted, she was too silent to give any praise, but if she had time to collect her thoughts, she might do that. 'You've seen her naked... several times... many times in life... why is this arousing you so much now?' Tiffany grumbled internally.

Samantha gazed over the pool, and though she was tempted to swim right away, instead flopped onto the lounge chair. "Now, let's just relax a moment. We can do pool time antics later if you want." Even with barely anyone around, Samantha hoped they could wait out the few people here, and have the pool in complete privacy. Not just for Tiffany's sake... but also to explore her own growing interests in outdoor exhibitions.

The bikini glad gave her sister a look, and was met with a blank stare, so Samantha just shrugged and closed her eyes, laying back in a languishing fashion. With nothing else for Tiffany to do but stare, she decided to pry her eyes away, and immediately regretted it, as she saw that she was finally getting attention. The older couple was starring on in shock, while the younger woman had looked from under her sunglasses.

She herself had dark red hair that flowed down her face, a serious face at that, with a body that had a chest nearly as large as Tiffany's, barely contained in a flame-patterned bikini. Her pronounced hips and legs made her seem like a giant; Tiffany knew this because she was now standing, and walking her way over. Tiffany was struck with a feeling of arousal she couldn't process, and the feeling only grew with the woman's continued steps forward.

The woman finally was in their presence, though Samantha had her eyes closed, not noticing the new observer. The woman however let her gaze slowly sweep between the two sisters. Tiffany was surprisingly nervous, and nearly yelped at the woman's prim sounding, "Ahem."

This gained Samantha's attention, so she leaned up to look at the woman. Tiffany's head swiveled back and forth between the two, noticing the new woman consistently stayed stern, while Samantha seemed to struggle with how to present herself in the moment.

Ultimately, Samantha gave a simple, "Can I help you?"

The woman simply said, "You two should come with me."

Samantha had worried this might happen, and though she wasn't fully prepared, she knew she'd do whatever it took to protect her pet... 'Er, I mean sister,' Tiffany thought to herself. Samantha propped herself on her elbows. "No thank you." She had intended to end the conversation at that, but she could have sworn she saw a flash of an expression shift in the mystery woman. But whether it was positive or negative was hard to tell with such thick sunglasses.

"I insist. Or you can go with the security instead."

Tiffany was tempted to speak up and join in this argument, but her arousal was starting to grow again. Two strong women were on either side of her now, and both were attractive in their own ways. Tiffany was still keeping her breathing under control, if only thanks to getting some pleasure last night; had she night, she would probably be even more of a mess now, maybe even vocal in that regard.

Samantha on the other hand, did not appreciate such an imposition. Attractive or not, Samantha did not intend to balk at the command of the mysterious red-headed woman. Samantha dealt with plenty of unhappy clients in her time as a paralegal, interviews that went wrong and debates from bosses who tried to push their attitudes around. That said, there was something different about this lady, and she felt a chill clawing up her spine for some reason.

"And who are you to give such an ultimatum?" Samantha asked, grimace forming on her face. That grimace was about to shift to concern.

"I'm one of the owners of this resort."
