[Kim Possible ABDL] A Matter Of Time

Kim wakes up one morning with a weird feeling. Why is there a test to determine if you should be sent BACK a few grades? Why does it hurt to think about it? And why did she dream about fighting the superhero, Shego?...


Chapter 1
Complete Story

"Kim Possible's spirit will be crushed!"... 


"KP look out!"... 


“Have fun being stuck in diapers princess!”...


"It's gonna blow!"... 


Kim gasped as she leapt up from her bed, ready to fight. She took heavy breaths as she searched the room for danger. When none presented itself, she realised what had happened. "Just a dream… just a dream" she whispered. She sighed and sat down in her bed. "Too late to go back to sleep too" she groaned. School was already hard enough for regular teens, but also having to regularly save the world was a whole other ball game. 


She walked to the bathroom and stripped out of her sweaty clothes to shower. Despite how vague the dream was, the parts she could remember were… concerning. It was more like a memory than a dream. But since it definitely hadn't happened, could it maybe be a vision? She snorted. "Turning into Ron" she said, brushing aside such a ridiculous theory. 


She basked in the heat of the water for another minute before exiting the shower. There's something I'm forgetting she thought. Her eyes widened and she bit her lip. "Results day" she whispered. Since she was a child, the government had introduced a new test to determine if students were in the right classes. Both to push forward more gifted students, and also hold back those who needed more help. In rare cases, students were even sent back a few grades. 


She groaned and held her head, holding onto the sink for balance. "That's definitely not right" she muttered. Drakken had to have hit her with something. Or maybe Monkeyfist? All she knew was that the idea of this test was backwards. 


She tried to not fall over as she got dressed, suddenly hit with vertigo. “Dammit! What the hell is wrong with me today?!” she whispered harshly. Kim took a deep breath again, trying to focus on standing straight. After a few minutes, the vertigo passed. “Haven’t felt that rough since Shego…” she paused. Why was I fighting a superhero in my dreams? She thought.


“But… she’s supposed to be a villain… I think” Kim muttered. Okay, something is seriously wrong she thought. She picked up her Kimmunicator and contacted Wade.


“Oh hey Kim. You’re up early” he said, downing whatever unhealthy breakfast he was having. “What can I do for you?”


“Wade, this sounds ridiculous but… I had a really weird dream last night. I know it’s stupid to be thinking too much about it but it just felt so real… and if I try to think about it too much I get really dizzy” she said, hoping he might at least be concerned about the second part.


Wade frowned. “That’s… unusual? And you’re sure the dizziness only comes around when you’re specifically thinking about your dream?” he asked. When she nodded, he sat back in his chair. “Uhm… I’ll have to look into this first. Could you just hold the sensor at the top of the Kimmunicator to your forehead so I can run some scans?”


She did so. “Whoa that’s a lot of activity… I’m gonna need to get back to you on this Kim. Try not to get into any fights today” he said, furiously typing away at his keyboard. Kim sighed as he hung up.


“At least I’m not completely insane” she muttered. She finished getting dressed and grabbed her bag. Her Mom was the only one up and hadn’t even started breakfast yet. “Morning” she said, trying to not seem troubled by her dreams.


“Oh, someone’s in a good mood” Ann Possible said. “Any particular reason you’re up so early sweetie?” she asked, pouring herself coffee.


“Nope, just woke up before my alarm” Kim said, putting 2 slices of bread in the toaster. “Have I to take the bus or do I get a car today?” she asked, grabbing her own cup of coffee.


Ann smirked at her daughter. “Are you sure you didn’t get up for something?” she asked. Kim scoffed. As if she had anything else to worry about. “You can take my car today. I have the day off. Something about it being illegal to let me work too many hours” she said, sipping her coffee. Kim snorted. Just like her Mom to work too much, even for a surgeon.


She buttered her toast and scarfed it down along with the coffee. “Thanks Mom. See you later” she said, not waiting for a reply as she grabbed the keys and was out the door. She checked her phone. “Still got an hour before school” she muttered. Just enough time to visit Wade.


She hopped in the car and drove off. As she drove, she frowned as she started thinking about her situation. "Wait… shouldn't I be getting ready for college?" she whispered. Her head started to hurt again, and she struggled to stay focused on the road. "Okay. Existential crisis can wait" she said, rubbing her forehead. When she finally got to Wade's house, she wasn't expecting much. Come to think if it…  why had she come here? They hadn't spoke that long ago, and he certainly wasn't a miracle worker. 


"Maybe he could get a better reading in person?" she muttered, not entirely believing herself. She knocked on the door and was surprised when Wade himself greeted her rather than his Mom. "I know it's a long shot but you've hardly made any progress?" she asked hopefully.


"Uh… sorta? I'm not too sure" he said, inviting her in. "Basically, your brain is full of highly active particles, and they're going haywire. The problem is… well I've literally just discovered them. Your head is full of something that humans had no idea existed" he said, offering her a can of coke. 


"... Well that's not what I expected to hear" she muttered, opening the can. In other words, there was nobody on the planet that could help her any faster. Remembering her thoughts in the car, she decided to bring them up. "Hey Wade? On the way over I was thinking about school. I sort of had an existential crisis because I thought I was in college and high school at the same time" she said. 


Wade paused and pinched his chin in thought. "Well… unless this particle has the power to travel through time then I'd say you just had an unrelated crisis there" he said, chuckling to himself. Kim laughed along with him. "Although I guess I shouldn't rule out that possibility. Physics can make no sense like that sometimes" he said. 


Kim snorted. It wouldn't surprise her if the boy genius figured out time travel. Wade did actually decide to take a few more scans since she was there. Kim glanced at the time and sighed. "Well, I'll pop by after school I guess" she said downing the rest of the coke.


"Maybe you'll be coming back as a college student" Wade chuckled as he tapped the keyboard furiously. She groaned as she got back in her car. Results day. Come to think of it… 


"When did I take that test?" she muttered, driving off. It nagged at her the whole way to school. Surely she'd remember taking it. She started biting her thumb as she drove. "Mom would kill me if she saw me doing that" she muttered, putting both hands on the wheel.


The whole school seemed more active than usual. It was normal this time of year. After all, the students would be finding out if they were moving up, staying behind or worse yet, being sent back through the grades. "Possible! You're taking up too much on the right!" 


Kim winced when she heard Barkin yell at her for an admittedly poor parking job. She made sure to reposition her car correctly in the parking spot and got out. "Much better. And you can come with me to my office" he said. Kim held back a groan, but only because Barkin seemed rather stoic. In other words, this was more serious a matter than just a shoddy first park job. 


She slung her bag over her back and followed him. "What's the matter Possible? Already get in trouble?" Kim turned to see Bonnie Rockwaller, smirking at her with hands on hips. Barkin stopped his march and turned to Bonnie. For a moment, Kim had hoped that she might actually get reprimanded for once in her life.


“Rockwaller, just the student I was looking for” Barkin said, flipping through pages. His words were fairly off putting. Usually, he’d be doing that drill sergeant shtick and start shouting at someone. Yet here he was, hastily looking through papers and looking rather solemn. “You will be joining Possible in my office” he said.


As he walked off, now with both cheerleaders in tow, he kept mumbling to himself. “Damn robots screwing up. Should’ve just gotten someone to check the pile…” he muttered, entering his office. “Take a seat” he said, walking to his desk and pulling out several more pages.


“Uh… is this a serious thing?” Bonnie asked, flopping down into the chair at the desk. Kim reluctantly sat beside her as Barkin slammed the papers down on his desk.


“There’s no getting around this… your test scores were lost” he said. Kim felt her heart skip a beat. “And until the matter is resolved, I’m legally obligated to give you both 0s for your score… which would send you back to Kindergarten” he said. Bonnie was the first to freak out.


“What the fuck do you mean LOST?! How the hell can they LOSE the damn tests and THEN say it’s basically a fucking failure for US?!” she yelled. Kim, while surprised that Bonnie actually said ‘us’, could only stare at Barkin with an open mouth. Her worst fear this morning had been that she might not graduate…


“Ms. Rockwaller, I have not slept since I found out about it late Friday evening. The laws around this were made far too strict. By law, I am required to send you both to Kindergarten until a time when the tests can be retaken… in 3 months” Barkin said, rubbing his eyes.


This time, Bonnie was silent as she too stared at him with an open mouth. 3 months would mean they’d be playing catch up with their peers the rest of the year! “Your parents were informed this morning when it became apparent that the powers that be weren’t budging. Personally I think a lawsuit is in order…” Barkin grumbled, pouring himself coffee from the pot.


For once, Kim could say she appreciated Mr. Barkin. If the mountain of used cups off to the side were any indication, he actually had been fighting for them against this positively ridiculous ruling. “You’ll be escorted discreetly out to the parking lot, where you will be taken to the Kindergarten… I’m truly sorry I couldn’t do more for you” he said. The last few days had very clearly taken a toll on him. It was like he was a completely different man.


As he said that, someone knocked on the door. “And that’ll be your… temporary teacher. Come in” he said. The girls both turned around to see Shego walking in. Kim grit her teeth as her head started to pain her again. Superhero. Villain?... Kim struggled to not let the thoughts go wild.


“Uh, I doubt we’d need protection to go to any school… much less a Kindergarten” Bonnie said. Shego snorted.


“Well it’s a good thing I got bored of being a hero and started teaching then” she said. “But we can laugh at my career choice later. You’ve got your own mess to figure out first” she said. Kim was barely paying attention. She saw glimpses of her and Shego fighting. Her and… a younger version of her? It took all her effort to not groan as the pounding in her head kept thumping away.


She barely even registered that she had gotten up and followed Bonnie and Shego out to the parking lot. Shego was… good? No, she was bad!?... Kim took a deep breath and exhaled as she got in the back, not putting up a fight with Bonnie as she hopped in the front. Shego started up the car.


“Obviously, we’re not just going to allow this bullshit to happen. As far as the kids and their parents are concerned, you girls are teaching assistants doing an internship for your degree. I’ve been told you’re not exactly the best of friends, but I’d ask you to at least ignore one another until this blows over” she said, glancing back at Kim in the mirror.


Kim nodded but her thoughts were elsewhere. Shego. Monkeyfist? Drakken? She gasped as quietly as she could, a flood of memories coming to her at once. She hadn’t had a dream! She grit her teeth and glared at Shego. One the one hand, she was right! This whole situation was entirely fucked! You didn’t send a pair of girls with their drivers licences back to finger painting!


On the other hand though, did Shego herself remember? She didn’t quite seem as goody two shoes as she had when she was Ms. Go in their original timeline. The correct timeline. But she seemed far more amicable than before. “Breathe Possible… breathe” she whispered to herself so neither in the front could hear. She closed her eyes and just focused on her breathing. Every now and then she’d cringe when she felt something in her mouth, but when she’d open her eyes, everything was normal.


They finally arrived at the Kindergarten. It wasn’t joint to any other school, looking more like a mature daycare than anything. “Try to get rid of your scowls, girls. The parents are going to be skeptical of you being TA’s if you’ve got resting bitch face” Shego said, getting out of her car. Kim snorted as she got out.


“Bonnie, you go inside. There’s a table facing the class where you two will sit. Kim, give me a hand with my equipment her please” Shego said, opening her cars trunk. When Bonnie was out of earshot, Shego sighed. “Please tell me you remember?” she asked.


Kim gasped and went to punch Shego, but the older woman caught her punch. “LISTEN TO ME! I know. Drakken’s little time travel adventure has sort of screwed you, but it’s WAY worse than you seem to think!” she said, grabbing folders out of the trunk.


“I am literally being forced to go back to a class learning their abc’s! How much worse could it be?!” she whispered harshly. Shego stared at her.


“Because you’re getting worse” she said. Shego reached into her handbag and pulled out a small mirror. Kim gasped and pulled her thumb out of her mouth, only being made aware she’d been sucking it. “Both you and Bonnie were doing that the whole ride over. And unless velcro is the new trend, your shoes have changed too”


Kim looked down and sure enough, her fashionable shoes had been changed to velcro sneakers. Not childish by any means, but certainly a far cry from what she’d been wearing before. Shego shut the trunk. “To be quite honest, I’d much rather not have to go back to changing diapers. Much less a grown woman's diapers” she said.


Kim flinched at the mere idea that she could actually end up pissing her pants. “It’s your fault this is even happening! And why the hell was Bonnie sucking her thumb too?!” Kim asked, trying not to shout for fear of the brunette hearing them inside.


Shego sighed. “Look. I’m not exactly a scientist. All that I know is that until this morning, things were… relatively normal. Don’t you have some genius computer guy that could help us with this shit?” she asked. Kim then remembered her visit with Wade.


“Yeah, but when I told him this morning, he said there were some particle things in my head that hadn’t been discovered yet” she said. Shego reached for Kim’s face and pulled the younger girls thumb out for her, making the red head blush harder than before.



“Well for both our sakes, he’d better figure it out fast. I don’t want to risk ending up in diapers either” she said, walking in. Kim glanced behind her and saw the first of the parents had started to arrive, so she followed Shego in.


She sat down in the chair beside Bonnie and watched as the kids started to come in. Glancing at her rival, she could see Bonnie was sucking her thumb. None of the kids or their parents seemed to take any notice of it though. She glanced down to see her own thumb was bobbing away too. She tried to pull it out, but found that as soon as she did then she wanted to put it back in. She sighed and relented to the urge. At least whatever was going on seemed to be making people think it’s normal for a couple of 18 year old girls to be sucking their thumbs.


Kim froze. If sucking her thumb had suddenly become… normal, then that would surely mean everything else that would happen would seem normal too! She blushed at the thought of her Mom collecting her later, and instead of being angry about this mess… she instead starts playing peek-a-boo with Kim. She blushed and did her best to wipe those thoughts from her mind. That wouldn’t happen.


She managed to pull her thumb out of her mouth just as Shego got the class settled down. “Hello everyone! I have an announcement to make! I’m sure you’ve noticed a couple of new faces. This is Kim and Bonnie, and they’ll be helping me with teaching for the next few months!” Shego said, her tone much more like her Ms. Go counterpart.


The kids broke out into the loud whispers younger children tended to do. Shego ignored it. “Kim and Bonnie are studying to be teachers like me, so if you have a question then don’t be afraid to ask them either!” she said. The sweetness of Shego’s voice didn’t suit her. Maybe it was that she wasn’t totally like Ms. Go had been, but it felt very much fake to Kim.


Still, Kim smiled through the whole thing. Glancing at Bonnie, she could see the brunette was doing the same… while she still sucked her thumb. Would Bonnie even think it was weird if Kim or Shego pointed it out? She hadn’t been involved with the time travel, so she probably wouldn’t remember how things were supposed to be.


“Now, please take out your notebooks. Your parents have said you’re all doing really well with your writing” Shego said. Kim sighed and got up, intending to help the kids. All in all, their work wasn’t exactly difficult. 5 year olds couldn’t really learn complicated things after all. The worst they’d have to worry about was their basic addition.


After about an hour, the kids were let do some menial task without help. She hadn’t been listening to what Shego said it was, only that she wasn’t needed for it. She sat down beside Bonnie, surveying the class as they worked and chatted with each other.


If there was one good thing to come of this, it was definitely Bonnie’s compliance. She’d never been so quiet around Kim before. Giving herself a quick look over, Kim held back a groan. Her sneakers now had lights on them that lit up when she walked, and she was fairly certain her green top was turning pink as she watched faint blue letters appear on it. They were so faded she couldn’t make out what they said.


She sighed and put her thumb back in her mouth. It was oddly calming to just sit there, sucking her thumb without a care in the world… almost kind of nice. She shook her head. Those thoughts could be dangerous. To take her attention off it, she glanced over at Bonnie.


The brunette seemed a little further along than Kim, now sporting a glittery t-shirt and a cute headband. She was dressed more like a mature tween than a young adult. Kim felt a sudden twinge in her bladder. She took her thumb out and leaned over to Shego. “Where’s the bathroom here?” she asked.


Shego pointed to a door at the end of the room. “Girls toilets are on the right. Signs need to be replaced” she muttered, keeping an eye on her students. Kim shuffled to it, suddenly feeling like her bladder was about to burst. She closed the stall door and almost tore her pants off when she pulled them down and sat on the toilet. She sighed with a smile as her bladder took that moment to let loose.


She closed her eyes, listening to the hissing of her pee hitting the water. “How did I not notice earlier?” she whispered, unwilling to entertain the theory that she might be losing her continence. Thankfully, her Kimmunicator beeped and took those thoughts away. “Hey Wade, hope you’ve got something” she said.


Wade looked a mess and was furiously typing away at the keyboard. “Kim, I’ve detected a LOT of activity from those particles near a Kindergaten! Can you… why are you looking at me like that?” he asked.


“Well I’m currently IN the Kindergarten. Long story but for the next few months I’m to act as a teaching aid here… with Bonnie… and Shego is the teacher” she said. Wade stopped typing and sighed.


“Damn, warn me next time you’re taking an unexpected trip Kim. I thought… did you just say you were a teaching aid at a Kindergarten with Bonnie and Shego?” he said, the explanation only hitting him now. Kim nodded.


“And what’s worse… me and Bonnie seem to be going backwards… what’s the word? Regressing?” she groaned, putting her face in her free hand. “We were both…” she blushed, took a deep breath, and exhaled. “We were sucking our thumbs and our clothes are changing. It’s almost like we’re getting younger, just not physically” she said.


Wade suddenly started typing much faster than before. “Okay, we definitely weren’t worried enough. Nobody else pointed it out to you? That you were… uh… sucking your thumbs?” he asked. Kim’s blush became redder and she shook her head no.


“Even Bonnie doesn’t seem to notice anything being wrong. Only me and Shego… oh yeah, and Shego basically confirmed that I travelled through time. She remembers as well!” she said, grabbing toilet roll to wipe herself.


“Huh… well congrats on being the first time traveller I guess?” he said, chuckling. Kim joined him with a giggle of her own. If not for the messed up test and the regressing, this was a monumental discovery! Drakken had actually managed REAL time travel. Travel that could actually affect the timeline.


She wiped the remaining pee off her crotch and tossed the wet toilet paper. “Well thanks I guess. I wonder if… fuck!” she whispered harshly. When she went to put her panties back on, she saw it. Around her ankles was no longer a pair of velvet purple panties, but a purple pull up. “Wade, please fix this fast… I don’t fancy ending up in diapers” she said, pulling her new underwear up.


They looked exactly like the pull ups she’d put on many kids she babysat. Except these were MUCH bigger. Anna from Frozen was on the front of it, which made her smile. She liked Frozen. She shook her head, suddenly feeling dizzy. “Kim? Just try to hold it back as best you can. I’ll see what I can do” he said.


Wade cut the call, leaving Kim to her problem of not slipping into that mindset again. She pulled her pants up and put the Kimmunicator away. “At least it’s not too noticeable” she muttered. The pull ups stuck out over her pants by about an inch but otherwise you wouldn’t know she was wearing them.


She sighed and walked back out. When she saw Bonnie, she really wished she hadn’t. Bonnie was sitting at one of the kids tables and seemed to be actively taking part in whatever they were doing. “Alright boys and girls! We’re going outside for the next lesson! Bonnie, Kim, could you two clean up while we’re out?” Shego asked, making sure all the kids had their coats on as she brought them outside.


“Not exactly giving us a choice” Kim muttered. When they were all gone, Kim decided to confront Bonnie. “Didn’t take you for someone who’d have fun with kids” she said, clearing up some construction paper from one of the tables.


Bonnie, who had surprisingly remained silent up till now, suddenly snapped. “Oh well EXCUSE ME for trying to ignore the fact that I’m basically being sent back to Kindergarten for a few months with the biggest bitch I know!” she shouted.


Kim flinched and her jaw dropped. Bonnie hadn’t made a snide remark, nor some witty comeback. She full on shouted at Kim. “It’s all well and good for you! SOME of us want to have a normal life that doesn’t involve your stupid fucking save the world bullshit! I NEED to get a college degree because I can’t get away with living off my parents forever!”


It was like the girl had been bottling up her feelings for years. And was finally letting loose. “Ha! That’s rich coming from you! Don’t BOTH your sisters already do that? Complaining to Daddy every time something doesn’t go their way like a pair of spoilt brats”


That had apparently struck a nerve with Bonnie as she pursed her lips and glared at Kim. With a much lower, and calmer voice, she spoke again. “Don’t compare me to those two leeches” she said, her voice barely above a whisper. At first, Kim had wondered if the time travel had changed the dynamic of Bonnie’s family. This certainly wasn’t the same bully she’d known from the original timeline, although she was just as bitchy as always.


It was either that or something serious had happened since the little incident where Kim and Bonnie had been stuck together. Deciding the conversation was over, Bonnie put her thumb in her mouth and resumed cleaning up, although with a much more menacing pace and movement. She almost seemed to be picking a fight with the tables by how she cleaned them.


Kim, noticing her thumb had also slipped its way into her own mouth, sighed and began to quietly clean up as well. They stayed at opposite ends of the room, only cleaning the table furthest away from the one the other girl was cleaning.


By the time Shego and the kids came back in, the tension between the girls was thick enough that even the kids seemed to sense something was off, though most were too busy talking to each other. Kim reluctantly sat beside Bonnie again, muscles tensed in case she actually started a cat fight. “Bonnie, could you… could you go clean yourself up?” Shego whispered.


Both Bonnie and Kim looked at Shego in confusion, then Kim heard Bonnie gasp. There was a small patch of wetness on her pants, although it was in a strange area. “Sorry…” Bonnie said, briskly walking to the bathroom with her thumb still firmly planted in her mouth.


“I’ll start catching flies at this rate” Kim whispered, noting how much she’d been staring with an open mouth today. Bonnie hadn’t just pissed herself. She’d pissed so much that she leaked onto her pants. It was fairly discrete. But it was there. “This crap is going too quick” she whispered again. At the rate the changes were coming about, Wade definitely wouldn’t be able to fix them before they were back in diapers.


Shego got on with her lesson, and about 10 minutes Bonnie came back out of the bathroom. Her clothes were completely different. Whereas Kim’s attire could still pass for a tween, no tween girl would be caught dead in what Bonnie was wearing.


She had a glittery Hello Kitty t-shirt on, along with flowery dungarees. Her short hair was tied up in pigtails and Kim swore she could make out a pull up at the side of the dungarees. When Bonnie sat down, she reached into her pocket and pulled out a pacifier attached to a clip.


Without any hesitation, she popped it right in her mouth and clipped it to her t-shirt. Kim quietly sucked her thumb as Bonnie sucked the pacifier. It looked… pleasant? And it would free up one hand... 


Kim gave a quick bite to her thumb. Those were bad thoughts to be having! She glanced down where she thought she saw the pull up and froze. It was way too thick and now that Bonnie was next to her, she could hear it crinkling. That was 100% a diaper. “Hurry up Wade” she whispered, begging to receive a call before she was in the same boat. Shego started handing out spreadsheets for the kids to work on. As Kim stood up to help her with it, she noticed something had materialised in her pocket. Reaching in, she pulled out her own pacifier with a clip attached. Her heart skipped a beat.


Her thumb was more mature… but the paci gave her both hands. She took a deep breath, and swapped her thumb for the pacifier. Wade would fix this. She just needed both her hands to do anything.


At first, it was odd. The taste, texture, smell, all entirely different than her thumb. But she couldn’t really say it was unpleasant. And as she sucked it more, she began to like it more. She went around helping the children again, now looking much more immature than before. She came up to a girl who was practicing drawing with the correct grip.


“Hi!” the girl said, smiling up at Kim. “My name’s Kim too! I love your paci!” she said. Kim blushed and giggled at the compliment.


“Fank ‘ou. Whatcha wowkin’ on?” she asked the younger Kim, eager to steer the conversation away from her little accessory. The girl started showing Kim her worksheet, although Kim couldn’t make heads or tails of what she was supposed to be doing.


“I’m writing the letter c a lot for Ms. Go!” younger Kim said, tracing the letter. Older Kim gulped. She didn’t recognise letters anymore then. Which meant reading was WAY beyond her now. She tried to think how her name was spelled, but came up short. She sucked her paci hard, trying to cope with her imminent regression.


Yet… something about it made her want to giggle. The idea that she was going back to such a carefree time of life… was it really that bad? She shook her head. Of course it was. She should be in college. Or fighting one of the many super villains of the world. Not standing here in a diaper trying to relearn the abc’s.


Kim gasped when she felt her bladder twinge again. She’d barely gone half an hour ago, but already felt full to bursting again. She pushed both hands against her crotch and did the potty dance all the way to the bathroom. Nobody even chuckled at her, let alone laughed.


She closed the stall and pulled her pants down. She sighed as she sat down, letting the pee gush out. While she was peeing, she grabbed her Kimmunicator and called Wade. “Wade, pweathe teww me you can filth thith!” she lisped behind her pacifier.


Wade glanced at her, and frowned. “Well shit. How did you get this device sweetie?” he asked. Kim felt her heart drop. And her stomach. And her pacifier. There wasn’t going to be any fixing. She had regressed so far that Wade had actually forgotten who she was.


“Buh… buh…” she whispered. Before Wade could speak again, the Kimmunicator started to vanish. Kim started sobbing, helpless as she watched her only chance of going back to a normal life vanished in her hands. After only a moment, she was sat holding nothing in her hand.


She sniffled. Tears started to fall down her cheeks. She shoved her pacifier back in, hoping for any form of comfort. Then she saw her pull ups. Or rather her diaper. She’d forgotten to remove it, and had just pissed in it on the toilet. She poked it. The warmth of her pee felt sort of good…


She grabbed a wad of toilet roll and wiped away her tears. She kept sniffling, but now she found it difficult to be so depressed. She… had to see the bright side in this… “That… free’th good” she muttered. She pushed into her diaper again, this time moaning quietly at the feeling. 


“Kim? You alright?” Shego called from outside the stall. Kim sighed and opened the stall for her. “Do you… oh no” Shego said. She must have looked a mess and was still on the verge of tears. “Is… is your friend not able to fix this mess?” Shego asked. Kim sniffled and shook her head.


“Wade no wemembew me…” she whispered. She caught a glimpse of herself in the mirror behind Shego. She looked ridiculous. Adorable too… but she was still ridiculous. An adult woman with her hair in pigtails, sitting in a wet diaper as she cried and sucked a pacifier. She could see her clothing change in the mirror too.


Gone was her tween clothes, now replaced by a pink onesie and baby booties. Shego helped her to her feet. “Did you make it?” she asked. Kim shook her head no. This time, Shego was stunned as she not only witnessed Kim’s clothes change in front of her, but also a giant changing table materialise beside the sinks.


“I really hope this is the worst it gets… because I doubt it’s going to get better” she muttered, helping Kim up onto the changing table. She unbuttoned the onesie and opened the diaper. “Nearly leaking” she muttered. “Uh… I’ll be back in a second” 


Shego briskly walked out of the bathroom, leaving her on the table, staring up at the ceiling. As she was left to her thoughts, Kim started to think about her future. Would she even go to school again? How will people react? She blushed as she felt a spurt of pee shoot out. She’d definitely be wearing diapers for a while. Maybe even the rest of her life…


And somehow that prospect was exciting to her. She imagined herself in her room, humping her pandaroo in her crib as she pissed her diaper. It brought a smile to her face. And maybe her Mom would even help her make cummies…


Shego came back in, large pink diaper bag in hand. She couldn’t read the word embroidered on it, but she assumed it was either hers or Bonnie’s. They were the only ones who needed diapers after all. Shego pulled out a pink princess diaper, which made Kim giggle. Shego smiled back at her. She actually looked sort of… depressed?


“Glad you can laugh at SOMETHING in this mess” she said. “Now, let’s get little princess Kimmie in her princess diapies” Shego said. She had Kim changed into a fresh diaper soon enough. “By the looks of things, you might have to get used to them” she said.


Shego picked her up, showing the strength that made her a superhero, and brought Kim back out to the kids and Bonnie. Kim giggled at what she saw. The kids were playing in the corner, and a few girls seemed to be playing house with Bonnie. Gone was her scowl, or really any look of general annoyance. Bonnie was all smiles and giggles as she crawled around after the now far more mature Kindergarteners.


“Kimmie!” Bonnie yelled as Shego placed her beside the brunette. Bonnie had clearly been chewing on her hair and her face was a drooly mess. She collapsed into Kim’s lap and giggled as she hugged her former rival. Kim joined along in giggling and playing with the kids.


This wasn’t as bad as she thought it would be. Maybe that was her mentally regressed mind speaking, but Kim was fairly certain she was legitimately having fun. She played with a stuffed bear and came up with wild adventures that the bear was going on. It wasn’t all too different to what she imagined her pandaroo doing.


Bonnie giggled and started humping her bear. The kids laughed and said she was wrestling it, but Kim could only giggle, knowing her former rival was getting off. “Kim, your Mommy’s here”


Kim turned to see Shego and her Mom smiling behind her. Something urged her to reach up to her Mom. Instead of picking her up, her Mom leaned over and covered her face with her hands. And just like that she disappeared! “Where’s Mommy Kimmie cub?” she heard her Mom say.


Kim looked around, genuinely confused at the magic her Mom had just pulled. “Peek a boo! Here I am!” her Mom said, revealing her face. Kim giggled so much that she felt her diaper start to warm with pee. “Thanks for taking her with the Kindergarteners. I could hardly get you to babysit too huh?” her Mom asked Shego half jokingly.


Shego smiled. “I’d love to actually. Kimmie might not know her abc’s yet but she speaks much more maturely than some of my students here” she said. Kim giggled. Shego and Kim herself knew that she was WAY more mature than the kids here. But her Mom definitely didn’t.


As her Mom kept speaking with Shego, strapping the red head in a giant baby car seat, Kim could only smile. This wasn’t so bad. She was still her, which was more than Bonnie could say. A bit more giggly and easily amused, yes. But she was still an adult in mind. She grunted, willingly pushing her poop into her diaper. “If I gonna be tweated wike a baby… (grunt) I betta enjoy it too” she whispered behind her pacifier.


She hugged her pandaroo that her Mom had brought for her. It was the truth. She was stuck like this. So it was much easier to just sit back, and enjoy the baby life.
