=====================
The door opened and Vicki stepped back inside to see her sister still kneeling obediently in the center of the floor with her hands locked behind her head. She was naked except for a thin silver metal collar locked around her neck. Her body quaked as a vibrator, lodged deep in her sex, kept her off balance and on the verge of an orgasm. Their eyes met for an instant before Vicki looked away.
In that instant before she averted them, Karen saw the shame in her sister's eyes. What had she done? What had she and Jo talked about? Jo entered right behind Vicki and closed the door. Karen hadn't seen her flip the switch but the incessant buzzing in her pussy ceased. She breathed heavily knowing that it could return at any moment. Apparently, Jo wanted her full attention so she waited patiently. Then something happened that Karen would have never predicted.
"Clothes off," Jo commanded.
Karen was confused for a moment, her clothes were already off. Then she realized the command wasn't for her. In amazement, she watched her older sister start to unbutton her jeans and then peel them off. Vicki wouldn't look at her even as she pulled the t-shirt over her head. Her strong, confident older sister was standing there naked with her head slightly down and her arms fidgeting like she wasn't sure what to do with them.
"Karen, go look in my bag and find the other remote vibe like the one you're wearing," Jo said.
Karen's eyes went wide but rose and found the device after only a few seconds of searching. It looked like a big, pink sperm with a weird tail. She looked back at Jo wondering what to do now that she had it.
"Vicki, center of the room with your hands on your head and your legs spread," Jo intoned in a smooth, even voice.
The older sister did as she was told taking slow measured steps to the indicated spot and assuming the position, closing her eyes momentarily.
"Help your sister out and put it in for her," Jo ordered.
Karen paused there momentarily processing what the woman had said. She then approached her sister slowly with the vibrator cradled in her hand. Vicki still wouldn't meet her gaze. The brunette pressed gently and felt the device slide between her sister's lips easily. She was soaked.
She looked up at her sister's face and only then did Vicki look at her. There was pleading and need in that stare. But what was she pleading for? What did she need?
Karen used two fingers to insinuate the head of the vibe into her sister's hole. It resisted, then, with a faint slurp, the thing was practically sucked in leaving just the tail still protruding. Vicki let out a faint sound of surprise and her eyes widened momentarily. That look was so beautiful, Karen thought.
Her fingers lingered on Vicki's pussy. It had been so long since she had touched it but it still felt familiar. Her sister was so close to her and getting closer. Karen continued to move toward the older woman. Their breasts started to press together and their mouths reached for each other.
Then both women groaned and Karen stepped back as their vibrators activated simultaneously.
"Oh, fuck," Vicki exclaimed through a moan.
"I didn't say you could play with her," Jo admonished.
"S..sorry...Sir," Karen managed through the buzzing in her groin.
The vibrations stopped and the sisters breathed a sigh of relief.
"Now," Jo continued. "Go get the other collar. You know where it's at."
"Yes, Sir," the brunette answered quickly and moved back to the bag and the special compartment where her collar had been.
She pulled out the second one along with the small lock and started to walk back holding it out to Jo. The taller woman shook her head and Karen stopped in her tracks.
"Vicki, turn towards me and kneel," Jo said.
The older woman took a deep breath then turned and went to her knees at Jo's feet. Vicki was still trying to decide how she felt about all this. Her body was telling her that it wanted all of this even as her mind kept resisting. It's only for a day, she kept telling herself. She could follow orders for a day.
This whole process with the collar was symbolic, she knew, but it still felt like something significant. If she hadn't had assurances from Jo that it was temporary and that her submission would make it temporary for Karen as well, Vicki was certain that she could never have gone through with it. There was just something scary about locking a piece of metal around your neck when someone else had the key.
But it had not been temporary for Karen, not in her mind. She had given herself to another person as a collared slave. She craved ownership, being someone else's cherished property. For her, the collar meant permanence, an unbreakable one-way contract. Her life was no longer hers and, for Karen, that was paradise.
Jo squatted down so that she was at eye level with Vicki.
"While you wear this collar," she began, "you are mine to do with as I please. Do you understand?"
Vicki looked at her kind, stern face and nodded. Just one day.
"You will do everything I tell you no matter what or you will be punished," Jo continued. "Do you understand?"
Vicki closed her eyes. One day. She nodded once again. Would Karen thank her for this?
"I need verbal consent, Vicki," Jo insisted. "Karen, tell her what to say."
Karen's heart was probably beating faster than Vicki's at that moment. Thinking about her sister joining her as Jo's property had her almost as excited as her own collaring. She bent over to whisper into her sister's ear.
"Say that you want to be her collared slave," the younger sister said. Then, on an impulse, "I love you, sis!" And followed that with a kiss on her cheek.
Another moment of doubt crept in as Vicki formed the words in her head. Why was this formality necessary? She had already agreed to submit for the day. It was that agreement that pushed her on, this was just part of the roleplay, she knew.
"I...want to be your...collared...slave," she repeated haltingly and somewhat flatly.
Jo smirked noting the lack of conviction but didn't push the issue.
"Karen, please lock the collar around your sister's neck," Jo ordered.
"Yes, Sir," came the reply.
Vicki watched the hinged metal come down from above and then felt the cold touch of it on her throat. She heard the two ends come together and the click of the lock. She could do this for one day. For her sister.
Jo then came around to the back and used some tool to secure the thing together. As the collar settled around her neck, she reached up and tugged on it feeling its solidity. Even knowing it was for show, there was something very... visceral about this whole ceremony. Vicki decided to try to relax and enjoy the experience. Fighting it would just ruin the day for Karen. This might be fun if she could just hold her own nature in check.
She tried to imagine what Karen felt when Jo had locked the collar on her. She would have been excited and turned on. She would have been so happy to not just be desired but claimed, marked as owned by the collar. Now she was marked as well. Vicki took a deep breath and felt the stirring between her legs at the anticipation of what was in store for her, for them.
Jo stepped forward and put a hand on Vicki's head.
"Good girl," she praised and stroked her head.
This was so demeaning, she thought, but then tried to put herself in Karen's shoes. Her sister would have felt genuine pride and gratitude for the compliment and affection. For a moment Vicki felt that too and pressed against Jo's hand as it held her cheek. The taller woman stepped beside her and pressed Vicki's head against her thigh. It was such a gesture of affection that Vicki melted into it for a few moments. She closed her eyes and concentrated on the warmth on her cheeks.
Above her, Jo had pulled Karen into a passionate kiss, the two of them melding like two long-time lovers. Vicki glanced up to see what was happening and found herself a little jealous. She just wasn't sure who she was jealous of.
Jo moved a half step back bringing the younger sister with her. At the same time, she kept Vicki's head stable so that after the movement her cheek was no longer on Jo's thigh but pressed against Karen's. Vicki closed her eyes again and just waited.
The hand holding her in place left and Jo was breaking off.
"Who else is hungry?" Jo asked out of the blue. "Let's go get some breakfast."
Vicki's eyes went wide thinking that Jo meant to parade them around the ship like this.
"Get dressed," the pilot started then, after a short pause, added, "and leave the vibes in."
Karen offered her sister a hand up which she took. As Vicki stood up, the two just looked at each other. Vicki had the urge to kiss her sister just as Jo had, but something still kept her in place just looking at the beautiful woman her little sister had become.
Then both of their eyes closed and they separated as the vibes went off simultaneously. It wasn't hard but it got their attention and they both leaned forward, off balance. Vicki put her hand out and steadied herself on Karen's shoulder only to feel her sister do the same, the two holding each other up. The vibrators were nestled against their g-spots and it shot pleasure through them like tiny jolts of electricity.
Just as Vicki thought she was going to end up on her knees again, the vibrations stopped.
"Isn't that neat," Jo teased. "Your vibes are synced in my app here," she said turning her phone around to show them. "Whatever happens to one happens to both."
She flipped the phone back around and touched the screen. Both women cried out as the devices inside them came to life again this time much stronger. It lasted only a second leaving both sisters' mouths open and taking short breaths.
"Now, get dressed. I'm not going to say it again," Jo commanded.
"Yes, Sir," Karen said and went straight to get her clothes back on from the previous evening.
Vicki said nothing but looked around and located her garments.
"Did you hear that, Vicki? That's how you will address me, as 'Sir'. Do you understand?"
Vicki's eyes darted toward the pilot momentarily but kept getting dressed.
"Y..yes...Sir," she managed quietly.
"A little louder, please," Jo insisted.
"Yes, Sir, I understand," Vicki responded louder but without a lot of conviction.
Jo smirked but didn't say anything else. She just watched as the two got dressed.
"Hm," Jo said as the two turned around as dressed as they could be. "That is not going to do. I can't show off my new pets like this."
Pets?! Vicki screamed in her head but managed to keep quiet. One day, V, just one day, she kept repeating in her head. Karen, however, seemed to enjoy being called a pet. The older sister knew that turned-on look that she had enjoyed eliciting when they were younger.
