"Nooo!" Sierra wailed, squirming unhappily on her tummy and trying to look behind herself. She knew what was coming, but she couldn't see when, which made it feel all the more threatening. "No faiw!"

"I'm sorry, but this is for your own good," Madison told her, patting the girl on the bottom and making her jump a bit at the touch. "You know you aren't supposed to hold it like that. You are starting over, and that means giving up all your control, even over this, to prove you're ready to start again. Unless you just want me to take it from you."

"No!" Sierra shook her head. She knew quite well, from Zoe's hypnotic triggers, what it was like to be incontinent temporarily, and she didn't want to have to go through that with Madison, especially since she had no idea how long Madison would make her stay that way. She wouldn't be surprised if Madison made her potty train all over again! "I don't wanna use my diapews!"

"Well, I'm sorry, sweetie, but you're going to," Madison informed her. Sierra gave a little gasp as she felt the small nozzle being gently pushed into her bottom, slowly gliding further inside her.

"Maddy, no!" Sierra wailed, whimpering as Madison's hand closed around the enema bulb and Sierra felt the small rush of liquid gush into her before the nozzle was removed and Madison tossed it into the diaper pail. Madison didn't even have to say anything more, since that action made it very clear that, yes, Sierra was going to be using her diaper, and very soon.

Madison turned her over right onto a waiting Pamper, lotioning and powdering her up well before taping it into place, then picking Sierra up off the changing table and setting her down on the floor of her room. Sierra pouted, looking up at the table where the skirt she'd been wearing over her diaper was still sitting. "I'm cold!" she insisted, reaching up for it.

"It is not cold in here, young lady, and you know it," Madison reprimanded her, giving her hand a light smack, as if the girl had any chance of actually reaching the skirt. "It'll be time for your bath by the time I change you anyway, and then we can put you into your PJs."

Sierra crossed her arms sulkily. "When I get pneumonia, it's gonna be youw fauwt!"

"Of course," Madison kissed her on the forehead. "Why don't you think about being a good girl? I'll be in to get you for your bath in a bit."

Sierra glanced over at the cute kitten shaped clock hanging on her wall with a frown. "But bafftime isn't fow..." she started, only to realize Madison was already gone. Madison kept her on a very strict schedule, and bathtime was a little over an hour away! Was Madison putting her to bed early because she'd protested so much? Was she planning on making Sierra stay in her soon to be messy diaper for that long? Or, as usual, was she just acting like Sierra didn't know how to read the clock since she was in the body of a four year old?

None of those possibilities made her very happy. She scowled over at the closet door, behind which all of her clothes were held captive. Madison had put a safety cover over the knob, to prevent Sierra from changing her clothes to what she wanted to wear, and it was quite frustrating just how effective that bit of babyproofing had turned out to be. It hadn't even required any magic! Sierra's toddler-sized, and strength, hands were just no match for it. The top of the changing table was also purposely too high for Sierra to reach from the floor, mostly to make sure she didn't try to jump off and run away, although it also worked to keep anything on top of it, like Sierra's skirt, out of her reach.

She groaned, wrapping her arms around her tummy as the cramps started. She wouldn't be able to last long at all! "Stupid Madison!" she sulked, stomping her foot. "It's no faiw!" Unhappily, she toddled over to her toys, sitting down delicately on the floor to try to take her mind off her current problem as much as she could.

While she didn't mind having a very valid excuse for sleeping with a ton of stuffed animals, it was quite difficult for the rest of the toddler toys to keep her attention for long. Madison liked to use the dolls and dollhouse to 'help' show Sierra the right way to babysit, which only made Sierra more annoyed. There Madison was, a girl that she used to babysit, acting like she knew more about taking care of kids than Sierra did! Sierra had a ton of babysitting experience! Just because she was a kid now didn't mean she didn't know how to do it!

So she usually stayed away from the dollhouse when she was playing alone. The only thing that really helped keep her mind busy was her wand, the toy one that Santa had given her for Christmas. Sometimes practicing with it was nice to remind her that she really was an adult, by mentally travelling back to when she was in school, learning all these spells. Sometimes, like now, as she sat there in just her diaper and t-shirt, trying desperately not to fill her pants, it just made her more angry about her situation. Why couldn't Santa have just given her a real wand so she could make herself big again?! She knew she had to look like a silly baby just waving a stick around, since it was impossible to produce as much as a spark from the toy.

She whimpered as another cramp hit, and she desperately pressed her bottom against the floor beneath her, feeling a slight stickiness there, telling her that she'd been slightly too late. She wrinkled her nose. The longer she could hold it, the less time she'd have to spend in it, but already she could feel the end approaching.

Her skin crawled slightly as she felt the distinctive sensation of magic being used, and she scooted around, wondering what Madison was up to now. As if things weren't already bad enough! Behind her, however, wasn't Madison, but somebody else. "J-Jessie?!" she squeaked, hardly able to believe her eyes.

Sure enough, it was him. She'd met him back when she was still in school, and while he was a magic user himself, he wasn't a student there. He came from another dimension, and Sierra had been trying to show off some of her magic skills when she'd regressed him to a toddler, and then been unable to figure out how to change him back. They'd gotten it straightened out eventually, and he was back to his usual, adult self, and she'd invited him to come visit her whenever.

Unfortunately, she hadn't planned on him popping in on her in a situation like this! Now she was the baby, and moments away from using her diaper! He turned around to see her, making her blush as he said, confused, "Sierra?"

She started to shake her head, wanting to deny it and pretend she was just a little kid who happened to look like the witch he'd met, only to remember that she'd just said his name. Reluctantly, she nodded, grunting softly as her tummy contracted again. "H-Hi," she waved bashfully, hoping he hadn't noticed what had just happened as she tugged at the hem of her shirt.

She could see a small smirk starting to form on his face. As much as she wanted to be angry at him, it was hard to justify it. She'd probably had a little too much fun teasing him while he was regressed himself, so it was only fair that he be allowed to enjoy this turning of the tables, at least a little.

"What happened here?" he asked.

"I-I just had a wittle accident!" she replied automatically, her cheeks darkening a little.

"This looks like quite an accident," he said, looking around the room. Sierra's cheeks grew even redder as she realized he had been talking about her age, not the state of her diaper.

She looked up at him, trying to figure out what to say next. He wasn't particularly tall, though while they were both at their normal heights, he was still a good bit taller than her. Now, he looked huge, especially since she was sitting down. She would have felt a little better about things if she could stand, but she knew that if she did that, she'd be filling her diaper in no time!

"Weww, the accident is named Madison," she pouted.

"Her again?" he teased. She'd told him about her encounters with the girl at Thanksgiving, and the alternate version of her in the other dimension. "Did she decide she needed her dolly again? I can't say I blame her, you're pretty cute like that," he said, tapping her on the nose.

"I-It's a wittle mowe compwicated than that," she squirmed, biting her bottom lip. How much should she tell him? In the stories, Madison was just a cute little girl. Now, she was probably taller than him, and about the same age, if not older. "I was..." She winced as her tummy pushed out a small pile of mush into her diaper. She pushed her bottom harder into the floor, squishing the contents of her diaper but making her feel slightly more secure.

"She switched ouw ages, then wegwessed me even mowe!" Sierra declared. It was technically a lie, but it was close enough. "Pwease, you have to hewp me!" she begged. "I don't know when she's gonna change me back! I think she wants me to gwow up again!"

"Of course I'll help," Jessie smiled at her. "What do you think we should do?"

"Make me big, and make hew a wittle kid again," Sierra suggested. "Then she can't use hew magic, and we can get my wand back and fix evewything!"

"That kind of magic is pretty complicated," Jessie frowned. "Time magic can be pretty difficult."

"You said you'd hewp!" Sierra pouted. "You can't just weave me hewe as a baby!"

"I don't know, you look pretty cute as one," he teased, bending down and tickling her tummy. Sierra helplessly giggled and squirmed, gasping a little as her movements caused her diaper to fill up even more as she anxiously tried to push his hand off, wanting to get him away from her so he wouldn't smell her accident, if he hadn't already seen it.

"Stop it!" she ordered with as much authority as she could muster. "You wewe a pwetty cute baby, too! And I fixed you!" She decided to leave the 'eventually' out of that, even if it was true.

He pulled out his wand. It glowed for a moment before turning into a rolled up scroll, which he unrolled, revealing lines and lines of spells. "It's going to take some time to write down even one of those spells," he told her. "Do you really think I have time to do both before she comes to check on you?"

Sierra sighed, but she knew he was right. He'd told her a little about how magic worked in his world before, and it sounded like it could be useful at time, but writing spells down on your wand, especially when they were as complex as he was making this one out to be, sounded like a lot of work. He'd said he could also speak them, but that took more time than with the spells Sierra knew. "Fine," she said. "Make hew wittle. Then she'll be out of the way, anyway."

"Okay," he nodded. "How little?"

Sierra knew she ought to just make Madison her old age again, and put everything back the way it was supposed to be, but she couldn't resist saying, "Make hew two or thwee. That way it'll be a while befowe she can get into twouble again."

Jessie nodded again, reaching into his pockets and frowning. "Do you have a pen I can use?"

Sierra gave him a look, then glanced around her room. "Does it wook wike a do a wot of witing?"

"Well, I'm not sure where I put mine," he said. "And there's no way I could get through this spell in time without writing it down."

Sierra sighed. "Weww, I have some cwayons."

Jessie frowned, looking at his scroll, with all its nice, neat handwriting. "I guess that'll work," he said.

"They'we ovew thewe," Sierra pointed to her toybox.

"Could you get them for me?" he asked. "I'm trying to work out the right wording."

Sierra fidgeted, her tummy rumbling quite ominously now as she squirmed in her already pretty squishy diaper. They really didn't have all that much time, so she knew she ought to help as much as she could. She tugged at the hem of her night shirt, chewing on her bottom lip nervously. If only she hadn't been a good girl and cleaned up all her toys, then there would surely be a crayon tossed aside somewhere within arm's reach of her or Jessie. The toybox looked so far away, and the pressure in her bottom was growing every second.

"Sierra?" Jessie said. "Are you okay?"

"Yes!" she answered back, a little too quickly. Sighing, she glared over at the toybox. She didn't like messing her diaper in the best of times, and doing it in front of someone whose diapers she'd changed last time she'd seen him was even worse. But this was probably her best bet for getting out of this whole situation with Madison and making everything the way it should be again, so it was worth it.

She pushed herself up onto her feet, wobbling a little as she toddled forward quickly towards the toybox, chewing on her bottom lip as she waddled forward. The toybox wasn't that far, she told herself. She could make it, if she just concentrated really hard!

And, somehow, she did. She'd hardly believed herself, but her diaper was no dirtier as she finally reached the box. Smiling in triumph, she grabbed the lid and yanked, but it refused to budge. She frowned, tugging at the lid again, a little more desperately before realizing Madison must have locked it with her magic. She did that sometimes when she really wanted to make sure Sierra did something specific, so she wouldn't be tempted to play with her toys instead.

She gasped, moving her hands away from the lid as her tummy gave a push, and she felt the mess in her diaper growing again, much more quickly this time. She let out a small whimper, her legs bending slightly involuntarily, getting her into a better position for what she had to do. She clamped her hands to the seat of her diaper, trying to make it stop, but her body had waited too long, and there was no stopping it now.

"Oh, here's my pen," Jessie spoke up, pulling it out of his pocket. "I don't know how it got tucked away so deep in there." Sierra glared as she turned to look at him, diaper drooping slightly now, wondering if he'd known all along and just sent her over there to make this happen, or if it really was a coincidence. "Do you need a change?" he smirked at her.

"No!" she pouted, looking away with a blush. She squirmed a bit, wondering if he was still watching her, knowing that he could do it anyway. She'd changed him several times last time, so it would only be fair, even if he hadn't messed his diaper while under her care. He'd protested that he didn't need help, either.

"All right," he shrugged, after letting the threat hang there for a few moments, whether he intended that or not. "Just let me know if that gets too uncomfortable."

With that, he rolled out the scroll that formed his wand and began writing the spell out on it. Sierra hadn't gotten to see him actually do that for a complicated spell like this, so she was curious to watch, but her now full diaper made her too self-conscious to get close enough to see, so she wandered around the room nervously, wrinkling her nose as the mess in her pants shifted with every step, growing slowly cooler and even more uncomfortable. She was almost tempted to take Jessie up on his offer of a change, or at least see if he would help her up onto the changing table so she could do it herself, but she couldn't make herself bring up either of those topics to him.

So, when the doorknob began to turn, Sierra's diaper was still quite messy. Unfortunately, Jessie was still scribbling on his scroll, making Sierra's eyes dart over towards him. "Huwwy!" she urged quietly. "She's coming!"

"Are you ready for your bath now?" Madison asked as she pushed the door open. Sierra scurried over to her, trying to keep her from opening the door too far and seeing her visitor before he was ready.

"Yes!" Sierra nodded, trying to move the girl back out into the hall. "Come on!"

Instead, Madison turned her around, tugging out the back of her diaper. "Wow, you made quite the mess for such a little girl, didn't you?" she teased, making Sierra's cheeks redden, shooting Jessie a dirty look when she saw him smile. "This is what happens when you refuse to use your diaper like a good girl."

"Yes, Maddy," Sierra sighed. "Can I have my bath now?"

"I don't know," Madison replied, giving the seat of Sierra's diaper a firm pat. "Have you really learned your lesson?"

"Yes!" Sierra insisted, wrinkling her nose. "Pweeease!"

"I'm not so sure," Madison said. "You really need to get used to this. You know my special baby powder ought to keep you from getting a rash, so maybe you should just go to bed in this, and we can get you all cleaned up in the morning."

Sierra's eyes darted back over to Jessie nervously, trying to will him to work faster. "No!" she whined. "That's not faiw! I can't sweep wike this!"

"But you need to get used to it," Madison repeated. "If you really need your diapers, you're bound to have a messy accident in bed every now and then, so learning to ignore it so you can sleep would probably be a good idea."

Sierra fidgeted bashfully, sure that Jessie was having a hard time not laughing at the thought of her being sent to bed in her full diaper. "Maddddy!" Sierra pouted.

"We'll just get you into another layer of padding, just to be safe, then pop you into bed," Madison declared, grabbing Sierra's hand and starting into the room, despite Sierra's best attempts to stop her. "I think an early bedtime will be a fine punishment for how much you're talking back to me."

Sierra gulped, knowing that Madison was about to spot Jessie at any moment, looking over at him frantically, just in time to see him starting to roll the scroll up. It glowed slightly, then formed into his wand again. A ball of light shot out from one end, hitting Madison as she headed for the changing table. She kept moving, tugging unconsciously at her pants, which suddenly seemed a little too big, her steps growing shorter and shorter as she kept moving, before finally she nearly tripped as her pants fell down around her ankles, followed shortly by her underwear. She frowned, looking over at Sierra, only to realize that the girl was now the same size as her, and rapidly growing taller.

"What did you do?!" she demanded, standing in front of Sierra, now totally naked as her shirt and bra flopped down over her shoulders and landed with the rest of her clothes, revealing the now two year old girl underneath. Sierra felt a little huffy, hearing that the girl's voice, while higher pitched, still sounded much more mature than her own, but that was something she could fix. Sierra ignored her, starting to dig through Madison's clothes, searching for her wand so she could fix her own age.

"That wasn't her, it was me," Jessie spoke up, walking up next to the tiny girl and picking her up. "What do you think we should do with her, Sierra?"

"Get her in a diaper, quick!" Sierra piped up, still searching. "We don't want any accidents, do we?"

"I'm not going to have any accidents!" Madison insisted angrily as Jessie laid her down on the table, quickly getting her taped into a Pamper. "I'm not a baby!" Even as she said it, Jessie was smoothing the final tape down, and one of her tiny, chubby hands nervously patted at the thick diaper around her waist before the boy picked her up, plopping her down into Sierra's playpen.

"Whewe is it?!" Sierra growled, kicking aside Madison's clothes in frustration. "Whewe'd you put my wand?!"

"I'm not gonna tell you!" Madison stuck out her tongue. Sierra stomped over to the playpen, glaring at the girl, again smaller than her, the way it should be, through the mesh. Despite the size difference working the right way again, it was still difficult not to feel more immature than her, with her lisp and the fact that her own diaper was quite well used.

"Yes, you awe!" Sierra stomped her foot. "It's mine! Give it back! I beat you!"

"No, your little friend did," Madison reminded her.

"Should we go look for the wand?" Jessie suggested.

"No!" Sierra glared at Madison. "Not untiw we finish with hew!"

"She's out of the way, I think..." Jessie started to say.

"No!" Sierra yelled. "If she won't hewp, she can be a weal baby!"

"Mental regression?" Jessie frowned. "I'm not sure, that's pretty complicated. Maybe I should work on fixing your age first?"

"We have time now!" Sierra reminded him. "Come ooon!" She did want to be an adult again, but after all this time, it would be satisfying to see Madison as a real toddler again. "Oh, I know!" she said suddenly. "Maybe it would be easiew if she wasn't a baby the whowe time."

"What do you mean?" Jessie asked.

"Weww, she was sooo anxious fow me to use my diapews wike a weal baby," Sierra said, pacing a little in front of the playpen now, eyeing the girl standing inside. "Maybe she needs to know what that's wike. Make hew incontinent, but whenevew she uses hew diapews, it makes hew think wike a baby untiw she's changed." She grinned, watching Madison's reaction.

"Are you sure?" Jessie looked down at her. "That might be a bit..."

"Oh, no!" Sierra shook her head, coming up with another idea. "Do the opposite! Make it so she's mentawwy a baby, and is alweady potty twained, but when she has an accident, then she can wemembew being a big giwl until she gets changed!" She giggled. "Which do you want, Maddy? Do you want to be a big giwl who knows she can't contwol hewself, just dweading hew next accident that wiww make hew a fuww baby again? Ow a baby who twies hew best not to have an accident because she knows she's supposed to be potty twained, but when you do you actuawwy wemember you'we a big giwl, and want to stay in youw wet twainews as wong as you can?"

Madison looked out of the playpen at Sierra, shaking her head. Sierra knew she was probably getting a little carried away, but she couldn't deny this would be fun, at least for a little while. She'd probably take off whatever curse she went with after a day or two, but that would be plenty of time for Madison to learn her lesson, she was sure.

"Are you really going to do that to me?" Madison asked, not sounding nearly as nervous as Sierra would have liked.

"Yes!" Sierra crossed her arms.

"How about if I tell you where the wand is?" she offered.

Sierra paused for a moment, then smirked. "Then that'll just make it easier," she stuck her tongue out. She had all the power now, and she was sure Madison knew it. It didn't really matter where the wand was at this point, Sierra thought. Once they had this all done, they could take all the time they wanted looking for it.

"All right, then," Madison shook her head, raising one hand. "Accio wand!"

Sierra could only watch in horror as the wand shot in through the door, landing in the girl's waiting hand. By the time she thought to turn and demand that Jessie, "Stop her!" Madison had already flicked the wand, and Jessie was already shrinking before her eyes, turning into a toddler himself. Sierra turned back towards the playpen, gulping. "I-I was just joking!" she claimed.

"Oh, really?" Madison raised an eyebrow. "It sure didn't sound like joking, young lady. I think you need a taste of your own medicine."

"No!" Sierra pouted, stomping her feet. "No faiw!" Madison was even younger physically than she was, but she could still use magic! It wasn't supposed to work like that! Jessie must have messed the spell up! "You can't do this!"

"Oh, silly girl," Madison shook her head. "Do you really think I don't have a baby monitor in here? I heard every word you said, so I was ready for your little attack. I thought I'd see if you were mature enough to do the right thing, but it doesn't sound that way. Now, I think we should see how you like your own ideas."

Sierra started to protest as Madison waved the wand, but as she sparks flew out of the end of the implement, Sierra slowly began to forget what she was going to say, as well as why she was so upset, why her sitter was so little and in her playpen, what she was holding, and just about everything else. She sank to the floor, wrinkling her nose in surprise and disgust as she realized her diaper was icky and feeling a warm wetness as it became even more so.

"Yucky!" she pouted, pawing at the front of her diaper, having no idea how to get away from that feeling.

Madison waved her stick again, then started getting bigger, the way Sierra was sure she was meant to be, her diaper quickly popping and falling to the floor. Madison stepped out of the playpen as soon as she could, grabbing up her clothes and getting dressed before walking over to Jessie, pulling him out of the clothes he must have been playing dress-up in and carrying him to the changing table.

Sierra quickly grew bored with that, getting to her feet and waddling over to her dollhouse, plopping down in front of it to play. She whined as her bottom sank into her mushy diaper again, squirming uncomfortably as she sat there, playing until Madison came over to pick her up, carrying her to the changing table. "I'm pwaying!" Sierra squirmed, trying to pull away from her sitter's arms, even as she was being laid down on the table.

As soon as the diaper's tape was undone, it all came rushing back. Her cheeks turned bright red as she squirmed, staring up at Madison, then glancing around the room to try to find Jessie. "What did you do to him?!" she demanded once she saw him, already fast asleep in Sierra's crib.

"Just what the two of you were going to do to me," Madison replied. "Don't worry, I won't keep him here against his will. He's free to leave whenever he wants. And once he does, I'll think about removing your curse, too."

Sierra perked up at that, feeling glad that Madison was being so merciful, even as the girl taped her into a fresh Pamper, then carried her to the playpen, laying her down, then stepping back and waving her wand, transforming it into a second crib. "Night-night, Sierra," she said, bending over to kiss the girl on the forehead.

Sierra got to her feet as soon as Madison was out of the room, grabbing at her crib bars and staring over at Jessie. He could get them out of this! She started to open her mouth, wanting to shout at him to wake him up, then remembered what Madison had said before. She had a baby monitor, and she'd hear the whole thing. She probably wouldn't appreciate Sierra trying to keep Jessie up past their bedtime. But that was okay, she thought. There was always tomorrow.


---------------------------------------------------------------

Sierra woke up wet, ensuring that she didn't even know to think about talking to Jessie about this. She could just gaze between her crib bars, jealous to see Madison bending over and checking him, declaring that he'd stayed dry another night before taking him to the changing table to put him into a fresh pair of training pants and shortalls.

"You're soaked!" she said when she went to check Sierra, making the girl squirm and blush.

"I'm sowwy," Sierra sniffled.

"It's okay," Madison hugged her. "Everyone learns at different rates. Just because your little friend is younger than you and already almost completely trained doesn't mean it's bad that you still need your diapies."

By then, Sierra was already laid out on the changing table, her blush turning much deeper as she was changed. Sure enough, when she was set down on the floor, in a Pamper and short dress, it turned out she was a little taller than Jessie, who she guessed was probably about three. Madison picked him up, taking Sierra's hand and taking the two of them into the dining room, where a pair of high chairs were set up.

Immediately, Sierra was given a sippy cup of juice and ordered to drink up, while Madison watched her like a hawk. She had no choice but to do as she was told, and after a few minutes, Madison nodded, heading into the kitchen. Sierra didn't know how long she had, so she quickly set the sippy cup down, turning to Jessie. "Jessie, listen..." she started, only to gasp as she felt a warm wetness trickling into her diaper. By the time she noticed it, it was already too late, and she was already picking the cup back up, with both hands this time, going back to happily drinking her juice.

After breakfast, Madison announced that since they had missed bathtime the night before, they would have to do it now. Sierra giggled, knowing that she loved splashing around in the water, and the bubbles that Madison always put into the water for her. At least, until they got to the bathroom and her diaper was untaped and she was set into the tub with Jessie. Her cheeks burned as she tried to hide her tiny, toddler body in the bubbles, not wanting him to see her naked. Of course, he didn't know any better, and couldn't have cared less, but free of her diaper, Sierra was fully aware of who he was, and their history, and being seen like this just made her feel all the more self-conscious.

When bathtime was finally over, the two were re-dressed and dropped off in Sierra's room. Sierra knew there wasn't much time, so she quickly toddled over to where he was building with his blocks. "Jessie, you hafta wet youw diapew!" she insisted.

He looked up at her like she was crazy. "Nuh-uh! I'm not a baby like you, I don't do that!"

"You have to!" Sierra stomped her foot. "Don't you want to be a big boy again?"

"I'm a big boy because I don't do that!" Jessie insisted. "And that's why you'we just a baby, even if you'we oldew!"

"I am not!" Sierra glared. "You hafta listen to me, ow we'ww be stuck wike this until..." She gave a little grunt, squirming as she bent over slightly, her body moving involuntarily, though she was all too aware of what it was doing. She tried to stop it, but there was nothing she could do. If this was all the longer she could keep her diaper clean, she thought worriedly, right before the mental drain started, this might be a lot harder than she'd anticipated.

"Can I pway?" she asked, fidgeting a little as the mushy mess started to push out into her diaper.

"Okay!" Jessie nodded, scooting over a bit so Sierra could sit down, musing over the blocks as her diaper continued to expand beneath her, a pair of happy toddlers, at least for the time being.
