The answer may shock you...

"I...don't know. All these options kind of make me feel bad. They don't seem safe to do on people."

"This is a pet, not a person." Samantha wanted to correct the robot, but knew there was no use in debating it now. "Flight Services Inc. has multiple options for supporting the regulation of pets. The most selected option is using shock settings."

Samantha balked at that. "That seems like the worst one!"

The robot denied this, determined to pledge the safety and satisfactory settings Flight Services Inc. provided. "Negative. The shock setting allows for a varying level, and thus the owner can regulate the pet in quite humane methods."

"I...see." Samantha wasn't convinced, but the robot was pressuring her to make a decision. If Tiffany was in her situation, would she have been struggling to make a choice like this? "Do I...really have to choose something? I know she's my...pet, but I can't do that. Isn't there another option?"

The robot stood taller, and started to get some attention from the other passengers, which made Samantha feel uneasy. "This is your final warning, Tiffany Smith. If you do not make a selection, you will be fined $15000, arrested and delivered to Cancun police upon landing, relieved of all carry-on and carriable items, and temporarily lose possession of pet Samantha Smith." Not only would Samantha get arrested under Tiffany's name, but she'd be pushing a heavy fine on Tiffany, losing their stuff, and getting Tiffany confiscated by who-knows-who.

Sighing, Samantha finally said, "Show me the shock setting."

Nodding with its digital face, the robot then slid away the face to show the setting for Tiffany Smith, the pet. The settings went from 1 to 10, so logically Samantha chose 1. The only other options she could choose in this menu were called Positional Position Setting, and Bark And Noise Control Setting. Both settings had only two options, 'Zero Tolerance' and 'Mild Level'. Samantha left both settings at 'Mild Level', hoping that wouldn't restrict Tiffany too much from talking or moving; granted, she would be alone down there with no one to talk to, and she was probably not able to move much, but the added restriction shouldn't be necessary. With the last click down, the robot said, "Please stand by while regulation procedures occur."

Tiffany, who's rage against the machine was beyond all reason, suddenly stopped with a shock to her system. "What the fuck?" she said in a surprisingly calm manner.

The robot ruined this calm. "Foul language is not-"

"ARGH!" Tiffany screamed. The decibel level was beyond what Flight Services Inc. considered a 'Mild Level', so sent a shock to her again. It was minor, but enough to frustrate her greatly. Unfortunately, she was too angry to stop, and instead went after the source of the shocks, which she realized was the collar. She struggled greatly against it, but the collar was designed to withstand even the strongest of animals.

Every attempt to remove it came with swearing and grunting and yelling from the shocks. Normally, the shocks were less painful than even static electricity...but Tiffany was so enraged and loud, the shocks kept coming. The robot watching over her realized Tiffany must have a high pain tolerance, but even worse, that she was at risk of hurting herself severely. The robot sent this information to the robot in the cabin...

"I have received confirmation that the shock settings are being applied." Samantha released a breath, hoping this would be the end of this, and that she'd find some way to make it up to Tiffany. "However, your pet is resisting."

"Uh...is that bad?" Samantha had a feeling she knew what was coming, and braced herself for what she predicted.

"Yes," the robot confirmed. The robot's facial screen returned to the settings. "In order to protect your pet from causing further harm to herself, we recommend altering the settings."

Samantha sighed. Exactly what she thought. Tiffany would be so angry at this...but her behavior was jeopardizing the safety of both sisters. Samantha was not the type to given a punishment to anyone, but now she was being **** to. "I...guess I could adjust it again."

"For the safety of your pet and to prevent further incidents, Flight Services Inc. recommends a setting of 5 and to implement the 'Zero Tolerance' option for both Bark And Noise Control Setting and Position Position Setting." Samantha looked at the setting, and gave herself one last moment to think it over.

She loved her sister, deeply, and though Tiffany was always bad about showing her affection, she had to imagine Tiffany would show her love if she had the right opportunity. Samantha always wanted to form a stronger bond with her sister, and this trip was supposed to do that; now, she was putting that all to risk. If she did this, even if Samantha gave the reasoning, Tiffany wouldn't be happy...but if she didn't do it, they'd be screwed by fines and law enforcement, essentially ruining their lives, all because they were screwed by Flight Services Inc. and Tiffany's anger at the situation. Tiffany was right to be angry, but Samantha realized that, had she been naked and in the cage down below, she would never cause them this much suffering.

Maybe the **** was clouding her judgment, but even ignoring that possibility, something was very clear in Samantha's mind. Her sister was her responsibility now. That didn't just mean protecting her, but also making sure she didn't hurt herself or others. Samantha remembered the piercing grip Tiffany gave her, and looking down to her wrist, still saw marks left by her. Marks that would heal, but a memory that would not. Something was wrong with Tiffany, and though this wasn't the right way to deal with it, Samantha decided this was the best alternative she'd get.

"I'll choose the recommendations then."

If Tiffany wasn't so lost in the moment, she'd be impressed with how much she could yell. She was caught in a loop of swearing, screaming, getting shocked, and attempting to break the collar. At times she did stop, attempting to break the cage again, but was making zero progress. Of course, Tiffany, so lost in her anger, was sure that she WAS making progress, and was willing to put up with the minor shocks to accomplish her newest goal.

And then a much bigger shock came. And then she screamed in pain, and that came with a shock as well.

It was so stunning, she collapsed to the floor of the automated carrier. Forcing herself up, she attempted to whisper "What the fuck?" yet again. This time, she only got out "Wh-" before the debilitating shock coursed through her. It wasn't enough to make her lose balance, but it was enough to make her see what was going on. She attempted to kneel in the carrier, but got shocked for that too.

As she went to all fours, it finally dawned on her. The tables had fully turned against her. Her goal of making a naked pet succeeded...

"Pet has been fully regulated. This unit will monitor further should pet need further assistance. Thank you for flying Flight Services Inc." The robot rolled away, and though Tiffany saw it return to the shadows where it must be locking itself away, her thoughts lingered on one word.

'No, I'm...I'm not a pet.' Tiffany assured herself, making sure to keep her thoughts internal. 'A pet...a pet is someone like Samantha. Someone who loves to be in these situations. Someone who would get turned on being naked...in a cage...with a collar...someone like,' she gulped, pausing to center her thoughts. 'Samantha is the type to love this stuff, I know it. I...I can still turn this around. I just need to think.'

However, her ability to think was still clouded. Not by anger, that had been decimated quite thoroughly by the shocks; her thoughts kept dwelling of more passionate needs. 'I...will not.' And yet the fingers of her right hand were already back to work on satisfying the hunger of her lower lips.

Tiffany tried to use her other hand to forcefully pull away the first, but the collar interpreted that as an aggressive position, sending another shock her way. She yelped, got shocked again, and put her left hand down. She cursed herself for causing yet another shock, but she let the thought pass.

With some clarity returned, Tiffany tried to let herself think. This conflicted battle in her mind needed to be resolved. Tiffany knew that, at this point, all Tiffany could think about was stopping the masturbation, or letting it go full throttle.

She didn't want to let the more perverted side of her take over, but her mind made it easy to rationalize why she should give in. 'You're bored. You're **** for action. You're basically alone. You're just like your sister should be...and you're sure if she was here, right now, she'd be dripping with delight.'

Tiffany's pace quickened, and had to bite her lip to hold back a moan. The passionate feelings were becoming too powerful to overcome, and her desire to stop was turning into a fading memory. This was even better than any of her fantasies. Tiffany's greatest fantasy was to make Samantha her naked pet...and this wasn't it. And yet, she had never felt this in need of orgasm. 'I...can't stop it. But I should stop it...shouldn't I? Just because my body is...desperately craving this...I shouldn't just give in to orgasming in public. I can't justify that!'

If she had any hope of stopping herself, this was her last chance...
