[Age Regression, Diaper TF, Diaper Use]

"I wanna plaaaaay!"

"Yeah, yeah, you've got your toys, kiddo. Don't bother us if you don't need to."

Jane thought that she could make an easy bit of cash. All she had to do was take care of some woman's lil' tyke, Samantha, and then she could get a good few stacks worth. And once that was over and done with, she could head out to town and just enjoy the nightlife. At least, that's what she thought.

But it was just too boring. That kid was practically an infant. Despite the fact that she was very clearly ready to enter kindergarten, she was still playing with toys that were meant for babies. Rattles, silly little shapes that had to be stuffed into the right hole, those kinds of toys that she should've outgrown long ago.

And what was her excuse? Well, she didn't have one. She was just a little kid after all. But it was seeing her play with those toys that had bored Jane out of her mind, and instead of waiting for her chance to just head out and go to town, she called her friends and invited them over to make them try and alleviate the boredom that came with babysitting.

"I dunno, Jane. Playing with her might just numb you to the experience." One of the three friends that Jane had called over, Haley, brushed a hand through her long blonde locks as she rested up against the couch's armrest. "That or you might just find that you can't solve a simple puzzle. Wouldn't that be funny?"

"Funny's stretching it." Michelle, the second friend, said as she pushed up her glasses. Compared to the others in their little friend group, she almost looked out of place. In fact, she looked like she was ready to hunker down and study instead of going out after their little gig was over and done with. "But I suppose she's almost like an infant whenever she gets shitfaced."

"Pfffft. No way, she's still got control over herself whenever she's that drunk." The third and final friend, Riley, laughed at the insinuation that Jane would've been just like an infant. "Besides, you see that girl? She's still in diapers, even at that age. Jane might be a lil' stupid, but she's nowhere near that stupid. Trust me, girls."

Jane glared at Riley. "Really, you're saying that when I had to bust you out when you were this close to flunking like, every single semester? Come on, this ain't the time to call me stupid, no matter if I'm being compared to her or not." She said, taking her eyes off Samantha as she engaged in a verbal fight against one of her friends.

All while little Samantha watched and looked at all four of those big girls. Mommy had told her that just one of them would be her big sister for the day, but then she ended up inviting all of them over and... Well, it got really loud and now she didn't have a playmate. That was something that annoyed her a lot.

But what annoyed the kid much more than just being ignored... Was being called stupid. One of those big girls was calling her stupid! Okay, so she was a little kid, and Mommy always told her that she was going to have to grow nice and big and old before she'd be nice and smart like her. But that didn't mean she was stupid! She was a perfectly smart little girl!

And unlike most of the friends that she had made whenever she was off with Mommy, she had a little secret. Okay, it wasn't as little as her, but it was definitely something that she was told to be secretive about. If Mommy found out that she had used it recklessly, then she was going to get a spanking. But at the same time, she'd probably accept that it was the only thing that she possibly could've done against a bunch of meanies that thought that she was stupid.

Before she could get the better of the four meanies that were being really mean by calling her stupid, she needed something to channel her power. And though she had a nice ring rattle that made a nice sound whenever she shook it, there was a better one a little further away. All she had to do was crawl a little, anddd...

"Hey, the kid's crawlin' around. You sure that's okay?" Haley noticed the little tyke crawling, though she didn't bother getting up to try and stop whatever was about to happen.

Jane looked over her shoulder and towards Samantha, before shaking her head. "Nah, she's not getting in trouble or anything. Just let her crawl around, better than having her try and ask if we want to play with her." She asked, stretching a little. "Seriously, can't this be over and done with already? I'm getting all sore from sitting around and doing nothing..."

Michelle pushed her glasses up slightly as she observed the young girl that had now picked up a rather thick looking rattle with stars covering the sides. But she didn't move to do a thing, merely just watching as she enjoyed some 'peace' with her friends.

Not that she would've realized the true potency of the weapon that Samantha now had in her hands. It wasn't just a rattle, it was a wand. The wand that Mommy had powered up to ensure that it would work just as well in her little daughter's hands as it would in her own. And that meant that even though her magic was nowhere near the same level as Mommy's, it was going to do exactly what Mommy could do with that Wand.

"Aw, cute, the stupid little tyke thinks she's a wizard or somethin'." Riley said, grinning a bit as that 'wand' was being pointed right at her. "What's the matter, baby? What kinda spell are you gonna shoot at me? You gonna mess your diaper and then think you've cursed m-"

"Turn into diapers!"

Samantha cried out as a big powerful spark fired straight from that rattle, one that was colored the exact same as baby powder. And to the shock and surprise of the older girls, it actually did exactly what the young girl said it did. As soon as it slammed into Riley, the older girl's body started to secrete the same sort of powder, as she shrunk and shrunk and started to collapse in on herself, until...

There was nothing left of Riley. Well, not in her human form anyway. There was a big and bright-colored pack of diapers sitting on the same chair that Riley had been sitting on, with the older girl's figure imprinted on the packaging... And her face was printed on the front of every single one of those diapers too, just for added humiliation.

Jane, Haley and Michelle all looked at Samantha in complete and utter shock. The tyke could cast magic. What in the world had they just gotten themselves into? There was no way that they could possibly deal with something like that. And yet, as much as they wanted to leave and get away from her, the sound of her rattle was... really nice...

Samantha giggled as she waddled over to the big chair. "Okay, girls!" The lil' girl said, all while pointing towards the ground as the lil' balls inside of her rattle continued to fly around and make that mesmerizing sound. "Get down and I'll get you all a change! Mommy taught me how, so you're all going to be nice and cute!" She giggled, while pulling out a couple of those nice diapers that were a lot softer and a lot less mean than the girl that had been used to make them.

Riley blinked as she was still fully aware of what was going on. What in the world had that girl done!? Why was she able to turn her into diapers!? Why was she stuck looking straight ahead, and why were her friends actually listening to her!? This wasn't right, this wasn't supposed to happen! She was supposed to be wrapped around babies and ensure that they were nice and safe and all sorts of secure so they wouldn't make any messes!

Wait... No, no that wasn't right. She wasn't supposed to be used for that. She was supposed to be used to ensure that babies remained nice and clean. No, she was human, she wasn't a diaper! She wasn't meant to be soft, she was meant to be absorbent! N-No, no no no! She was... She...

Riley's remaining consciousness was having trouble keeping its identity straight, as the struggling face on the front of the diaper gradually shifted emotions. Until it slowly but surely became little more than a cartoonishly big smile, all because of her mind slowly accepting that she was definitely nothing more than a diaper meant for little toddlers. Girls that were smaller than Samantha, and there weren't exactly any around here that were fit for that.

Not that Riley would have to worry about being too big for the babies that were going to wear them. All she had to do was just point her wand at the nice big girls that were now laying down obediently on their backs, and then rattle it a bit to make sure that the magic was working as best it could. And then... Well, she was going to put their diapers on them! Easy!

All three of the older girls were shocked to watch their clothes very abruptly disappear, leaving them all completely and utterly naked. Not a single garment remained on their bodies, leaving them with even less modesty than the girl that was currently pointing a rattle at them. And yet... They kinda felt like they were supposed to be like this? Barely wearing anything, just enjoying the experience of being naked..?

It was something that dwelled on their minds as one by one, one of the diapers that had Riley's face on them slid underneath their butts. And one by one, each of them were being forced to wear them. Or it wasn't really forced, since they all just followed their instincts whenever the lil' tyke tried to help them put on their brand new diapees...

The first to get hers on was Jane. Because Jane was supposed to be the big sister that was supposed to take care of Samantha. But as that diaper slid right onto her, she couldn't help but feel like it was right. It was really right to wear it. It was like... She had been missing out on this for so long. And sure, it was a little small, but she could grow into it. Because she was still just a lil' girl who didn't know any better, but at least she had her big sis here to help her!

Haley wanted to try and fight back against the padding. It was way too tight around her waist and it dug into her privates. And yet the more she tried to struggle, the more she felt the need to suck on something. So she stuck her thumb into her mouth and started suckling on it. And that really helped. Sucking on her thumb always helped, why hadn't she thought about sucking on it earlier? She sucked and she sucked, and she slowly started to drift off as she forgot all about what she was worried about...

Michelle knew better than to mess with somebody that could use magic. So she just laid there quietly as she was stuffed back into diapers. And she didn't really think much of it. Sure, it was tight and it was a bit too soft, but it was just as undersized as her glasses were oversized. In fact, why was she using these anyway? She didn't need glasses, they were for smart people that were older and cleverer. She didn't need them, she was still a lil' baby!

As each of the girls were being stuffed into diapers, the magic that Samantha had secretly casted on them started to take effect. And little by little, each of them shrunk down until they were the exact same size as one another. The size of toddlers that didn't know any better. They were about half Samantha's age, and just one good look at the older baby...

It made them immediately recognize her as their dear big sister! They weren't even aware of the fact that they had been transformed thanks to her magic, nor were they aware of the fact that they were wearing one of their friends in the form of a diaper. They were just happy to be here with their big sister!

Samantha giggled and the younger girls giggled too. All of them looked like silly girls with big diapers around their waists, because the diapers were a lot bigger than the ones that babies like them would usually wear. Too big for babies like them, yet too small for adult babies. It was the perfect kind of diaper. Especially since there was still one important thing that had to be done. One thing that would not only make sure that the other babies were stuck like this, but also enjoyed every moment of it.

"Okay, who wants to play house?" Samantha asked, and all three of her 'little sisters' raised their hands. Not that they really knew what house was, but they wanted to play along with their big sister. "Okaaaaay. Then I'll be Mommy, and you all are gonna be my babies. Okay?"

The three nodded, giggling as they looked at each other. They were gonna be Mommy's big babies! But what did they need to do to be babies? It was something that hadn't crossed their minds. But it definitely felt like something was wrong. Like they were supposed to be... doing something. What were they supposed to be doing again..?

"To be Mommy's babies, you have to do something for Mommy, okay?" Mommy Samanta said, having taken the moment to change out of her own diaper and into another Riley diaper while the three babies were distracted by their own amusement. "You just have to push and use your diapees! Then you'll be babies, because babies use their diapees all the time! Even Mommy uses her diapee when she needs to!"

All three of the toddling babies nodded as they looked at one another. They were going to push and then they were going to push and they were going to be good babies for their Mommy. Even if it felt like something was wrong when they pushed, they wanted to make Mommy happy. And that meant that they just had to push even if it felt wrong!

In the back of their minds, it was like their older selves were screaming at them. Telling them that they shouldn't be doing this. That they were all adults. And yet those voices just grew quieter and quieter as they pushed harder and harder, right up until the moment that they went properly silent...

Because they had pushed them out. Right into the back of their diapees. Diapees that were now nice and full of poopy, making the three girls definitive and undeniable babies. And just knowing that was enough to make them all giggle together like the ditzy little toddlers that they were. They were happy to not have somebody yelling at them in the back of their mind. Especially since Mommy was smiling at them.

Samantha giggled herself, all while watching the faces on their diapers having turned all sorts of happy from being full. If the big meanie was still conscious and still able to be herself, those faces would've been frowning. But she had accepted her role as a diaper, and that meant that she was happy to be full. Maybe a little too happy, she'd have to ask Mommy if she could fix the meanie and make her look less like she was doing the same kind of face that Mommy made whenever she got too excited in bed...

"Samantha! Mommy's home!"

All of a sudden, Samantha felt the sweat running down her face. Oh no, oh no! Mommy was home! And she hadn't prepared an excuse. Well, she was going to tell the truth, but Mommy wasn't ready to see three stinky babies. Oh no, oh no!

Indeed, Samantha didn't have a chance to change anything before her Mommy stepped into the living room and put her eyes on the scene. It didn't take long for her to realize what had happened, once the shock of that sight had come and gone. "Oh, Samantha. What did I tell you about using Magic on people that don't know you're a lil' Witch?"

"Sorry, Mommy! But they called me stupid! And I'm not stupid!" Samantha cried out, a few tears trailing down her cheeks. Even though her Mommy hadn't really scolded her, she couldn't help but cry. She knew that Mommy didn't like it when she went against her. It meant that she had been a very bad girl... A very, very bad girl...

Mommy just silently rubbed her temples as she looked down on the young toddlers that had their diapers stuffed full of poopy, and the pack of diapers that had definitely been another girl. While Samantha had gone against her, so had the babysitter. And it seemed like they had paid for it...

"Alright. I'm going to have a talk with their parents, wipe their memories and make sure that they won't need to worry about those girls. And then you're going to be a responsible big sister and make sure they each grow up to be just as good a girl as you. Okay, Samantha?" Mommy said, and her little tyke started rapidly nodding, the tears giving way to a big and happy smile.

Well... Even if those girls were going to end up needing diapers well into adulthood, at least they were going to be happy growing up alongside her little girl.
