Keep her aroused but don’t let her finish

Abigail’s idea was simple but effective. She had played with the vibrator’s base and discovered when she turned it that it had 8 different settings before coming back around to being off.

“Since she’s completely malleable when aroused we need to keep her that way. The vibrator has several settings. One will have it turn on and off intermittently raising her arousal constantly but never letting her climax. We leave it in her vagina the whole way home. She’ll never come down enough for one of her fake panics where she tries to pretend she’s a person.”

Her mom smiled, “Abby, you are a genius. I’m so glad you’re our real child. We're so proud of you, making sure Lucy has the best care possible for her needs.”

Lucy was starting to calm down and remembering that she was being kept as a pet against her will. She realized she was naked in a crate collared and on all fours. She started to freak out a little but she had no room to move. Her arms were tucked under her and her ass was pressed against the back of the crate.

She tried to think of what to do but before she could get anywhere she felt the small vibrator from before. Instead of being pushed against her clit it was being put inside her. Her sister placed it with one hand between her vaginal lips. She moaned loudly as her sister pushed it with one finger between the grates until it was completely inside her wet and open pussy. Her sister then closed the trunk which Lucy’s bottom was pressed against it keeping it **** inside her.

A low buzzing sound kicked in as it started to vibrate and fill Lucy’s mind with haze again. She was moaning loudly as she tried to move her hands to squeeze her nipples and luckily that was about how far her hands could move. She squeezed them lightly as she felt an orgasm building. She was licking her lips and moaning and then... it just stopped. She didn’t understand what was happening. Her mind was clouded as she tried to even push her self back against the door hoping it would allow the vibrator to act as a dildo to fuck herself with but she couldn’t even push back she was packed in so tight.

Her parents got in the front seat with her dad driving and Abigail got in the second row. Abigail looked over the seats at Lucy in the crate and her eyes were glazed over as she started to come back but then the vibrations came back on and she was moaning loudly again. Her juices coated her thighs and her nipples were erect as she pinched them, hoping it would take her over the edge. Drool was running down her face. She wanted to reach back and play with her clit but she couldn’t move her hand that way. She just panted and prayed for an orgasm but then it stopped again.

Her dad addressed the family, “Don’t you just love hearing her happy like that?”

“She really is perfect isn’t she?” said her mom.

“Yes, she’s perfect just the way she is. I only wish we could go back in time and do it right from the start,” said her dad.

“We’re doing it right now, Dad, that’s what matters. No use dwelling on what we can’t change," Abigail said, "I mean I treated her like a big sister, deserving of respect and a source of guidance when it should have been the other way around completely. We just have to learn and move forward.”

“You’re maturing so fast," said her Dad, "You really know just how to put things.”

“And where!” added Abigail to the laughs of her family as the vibrator in Lucy’s pussy came back alive.

Lucy moaned and panted as she started to sweat and feel like her pussy was pulsating and sending electricity through her whole body. She filled the whole van with moans as she tried to think of any way to push herself over the edge before it stopped but then it did again. She groaned in frustration but her mind was too clouded to say or do anything.

The process of it going off and on continued for the whole trip. By mile 50 of 200 she had lost all sense of what was going on. She couldn’t get her bearings as she tried to even remember who she was or where she was or why. She felt trapped in the crate but she couldn’t even remember if she’d ever been anywhere else. The vibrations would always take her to the edge but not over as she was denied sweet release over and over.

Her family considered gagging her but felt like if something wasn’t going as planned they wouldn’t be able to tell without her loud moans.

Abigail turned around to see her former sister, and to her she looked as she should. She was covered in drool, sweat, juices and the smell of her pussy was radiating throughout the car. She was moaning softly as she hoped that an orgasm coming. The vibrations weren’t even on but she was shaking with need. Her nipples and clit were so erect they hurt.

Lucy looked at her sister, though she couldn’t tell she was her sister or if she knew her, as she reached back and touched her hand through the grate. The soft touch made Lucy smile as she felt like she’d never been touched by a person before. She wondered if this kind person would help her cum but in moments she had let go and turned back around to face the car. Lucy could see the back of the girl's head as the vibrations kicked back in and she was gone.

When the vibrations came back on and she was at peak arousal she started to lose whole moments. She couldn’t remember what happened but minutes of vibrations disappeared and she could only feel the time where they were off. She was becoming less and less lucid. Finally she was pushed forward as the van came to a stop. She wondered where she was as she heard people getting out of the car. She wondered where she was and even who she was.
