Yes, but with consequences

"Are you really sure? I mean, I'll try to protect you, but-"

"Ha, don't worry yourself, dear sister. I may be your, ahem, naked pet. But I can be brave. And like you said, there's hardly anyone around." Tiffany could easily all say this without flinching, but she still held back the truth that she felt more than just curiosity. She felt a bit of thrill, but she brushed that off as the idea that, in better circumstances, this would be Samantha's life right now.

"Don't interrupt, I'm not finished." Tiffany raised her eyebrows, surprised that Samantha actually fought back a bit. Tiffany didn't like it...but she also felt a tingling in her lower regions. Her brief confusion was enough for Samantha to continue. "I'll try to protect you, but if you're coming with me, you have to follow my rules."

"Rules?" Tiffany wanted to make that sound more defiant, but the attitude shift was throwing her off. 'What is this coming from?'

Samantha felt strange to be acting more in control, but there was something fun about it too, as if she was defying her fate. "Yes, rules. And if you break them, I'll have to...reprimand you." She considered saying "punish", but she worried if that was going too far.

Tiffany decided to take it too far. "What, I get punished? I'm trying to do you a favor!"

Samantha debated for a moment on what to say next. It felt a bit sudden to use such a term, but Tiffany brought it up, and Samantha almost wondered if she saw a hint of desire on Tiffany's face. Instead, Samantha compromised. "I suppose you could say that. But if that were true, that you were doing me a favor, shouldn't I see how a petgirl handles the consequences of misbehavior?"

That threw Tiffany off again. "Oh...well, I suppose, that does make sense, but..."

"Then I'd say that, as a consequence to your defiance, I'll be enacting this rule. While outdoors, you will be quiet, and you must do everything I say without question." It was a simple set of rules, but Samantha felt like she had just taken a major step forward. She felt the confidence flowing through her, dancing in her veins, and making sure to visit every erogenous zone that could be found.

And though Tiffany would be loathe to admit it, she felt the same way. Tiffany immediately rationalized it as feeling heated due to her defiant nature building inside her. For some reason defying her sister's commands felt good, and it reached a point where she debated pushing her luck even further. But she shook away any good feelings to focus solely on the defiance. Tiffany didn't want to believe Samantha would enforce any sort of rules. 'After all, she's a pushover, that's why I'm making her my pet in the first place. Although...'

While Tiffany was sure she could easily push back, she came up with a wicked idea. She'd let Samantha lead for now, and when Tiffany did make her push back against Samantha later, she'd prove to Samantha that she couldn't handle being the master, and would have to be the pet.

Tiffany shrugged. "Fine, I can obey."

Samantha was surprised how quickly she gave in. Even Samantha, who was unaware of all of Tiffany's schemes and thought process, knew to be suspicious. 'That was too sudden, there's definitely a trick attached here. Still...if Tiffany does try to trick me, she's going to be quite surprised at the consequences for that.'

Although trickery seemed afoot, Samantha decided to shrug in turn, and motioned for Tiffany to approach. "Well, if you're coming with me, I'll need your leash." Tiffany didn't freeze or tense up externally, but internally she felt like every muscle had frozen over. Samantha didn't notice, but she wondered what was going through Tiffany's mind.

Slowly Tiffany reached for the leash, laying on the floor but still attached to the collar, and raised it up for Samantha to grab. Tiffany couldn't tell if Samantha thought this slow movement was suspicious, but Tiffany kept cursing herself. She knew she couldn't stop, to avoid showing weakness, and going too fast would make her seem like she was into this whole thing. It was a careful balance, and she had only a vague hope that it was paying off.

Samantha felt confused why Tiffany was moving slowly, but internally shrugged and grabbed the leash.

"So, should we go now?" Samantha asked. Tiffany nodded, and Samantha approached the door to the apartment. Now it was Samantha's turn to slow down. She was taking a big risk, as being seen with her sister like this could be really hard to explain. 'Well, if I going to be her master, I'll have to take on that responsibility.' She looked down to her sister, who gave a blank stare in return. 'I'll make this work.'

As the door swung open, Tiffany couldn't prevent herself from catching her breath. For some reason she felt even more nervous than the other day in the lobby. Tiffany was naked, on all fours, collared and leashed and dripping fluids she wanted to deny existing. Yet this time she was doing all this by choice. The last bits of her doubts screamed in her mind, telling her to stop all this before it was too late.

But it was already too late. Samantha took the first steps out of the room, and pulled the leash; Tiffany had **** but to follow. Tiffany crawled her first shuffles into not just the outside world, but into a world of willing submission. And, despite all the denial and confusion of her feelings, Tiffany's arousal grew stronger with each moment. She'd need to find some way to calm herself, or admit that she truly loved this.

As for Samantha, seeing the empty hallway made her feel relieved. She had a feeling she'd be in a tight spot eventually, but she was building confidence with every step. She almost felt the urge to stride, but she could tell Tiffany wouldn't be able to crawl fast enough to keep up. Instead she merely took light and easy steps. She could hear Tiffany breathing, a bit heavier than usual. 'Probably trying to calm herself, makes sense.'

Going down the hallway was uneventful, which gave Samantha the opportunity to give the occasional glance to her pet sister. She could tell Tiffany was different, no longer was she moving with cockiness or aggression. Every move felt careful and deliberate. At first Samantha assumed that it was a case of nerves, as anyone doing this would logically feel. But Samantha could smell the faintest hints of arousal, and couldn't resist smirking.

'My little sister...I'm learning so much about you on this trip.' Samantha felt a strong temptation to say it aloud, but held her tongue. She knew she'd have plenty of time to tease her sister, once Tiffany was more comfortable embracing this unique side of her.

Samantha walked Tiffany to the end of the hallway where the elevator was. "Press the button, Tiffany."

Tiffany looked to the button, and back at her sister. "It's too high up, I can't reach."

Her sister took on a more stern look. "Tiffany, press the button, now."

'Stern voice, huh? Real nice sister, but you can do better.' Tiffany couldn't resist a small grin emerging. "Do I have to?"

"Pet. Button. Now." That evaporated the grin quickly. Samantha's expression had only slightly changed, but Tiffany as if she had just been struck with a strong aura of authority.

Awkwardly, Tiffany grumbled, "F-fine, whatever." She turned and slowly reached up for the button. Tiffany was about to mock that she still couldn't reach it, when suddenly a hand came right against Tiffany's rear. Her right cheek barely jiggled, but to Tiffany it felt like she had felt tremors throughout her entire body. Her pussy, which was finally starting to cool a bit, was ignited even more than before. 'Did...did she just spank my ass?'

Stunned into silence, she slowly turned to face Samantha. Samantha had a face more stern than before, and waited several seconds before saying. "That's for the defiance. The next one is for speaking in public."

Tiffany was mind-blown, but did not to stop Samantha as she prepared for the next slap to her butt. In fact, she was strangely craving it, and did nothing but turn to face forward, as Samantha's hand met her left cheek. Truly, the most horrible thing in that moment, to Tiffany at least, was that she yelped.

As for Samantha, her mind was blowing too. A strong instinct entered her mind, she needed to show discipline, and though she wanted to make it a light tap, she also knew she couldn't show weakness. So, with a solid amount of power, she had swung. Tiffany's attitude shift was noted, but not important, as by Samantha's count, she had disobeyed twice.

When the second smack came down, Samantha's internal panicking seemed to fade. She still felt nervous, but she felt better about it. 'If the roles were reversed, would Tiffany be spanking me?' Samantha looked down after landing her palm, and noticed Tiffany's pussy lips practically shining with pleasure. 'Ah, never mind, she's the type to prefer being spanked.' Despite the older sister's prior reservations, she was feeling quite satisfied now.

Tiffany, on the other hand, felt a satisfaction she couldn't, or rather wouldn't, fathom. Being aroused by the dominance felt like too big of a subject to currently analyze, so Tiffany merely followed her directive and leaned up to press the button. She tried to remind herself that she was supposed to be defiant, but the petgirl worried that, if she felt more spanks, she might just cum in that moment. She had no idea how to justify such a release with her delusions, so Tiffany resumed her position on all fours.

She turned to see Samantha smiling. "Good, Tiffany, much better. Remember the rules, and I promise you'll have a lot more fun on this trip than a couple of spanks." She gave a wink to Tiffany, not only showing she could tell Tiffany enjoyed the butt smacks, but that she was growing more confident in her role. This felt so far from what Tiffany had ever imagined, and yet exactly right, just with a role reversal she never would have imagined before this trip.

Luckily for Tiffany, her concerns were halted with the arrival of the elevator, an empty one at that, and Tiffany sighed with relief.

Samantha smiled. "Don't worry, this night isn't over yet, and I'll make sure that whatever happens stays just between us."
