Sierra looked at herself in the mirror skeptically, wondering if she should change yet again. It seemed like nothing she tried on looked right!

It might not have been so bad if it wasn't so hot out. This wasn't her first babysitting job by a long shot, but it was the first one that felt professional. It was the first that wasn't just for one of her neighbors, and that was meant to be long term, so she wanted to impress what sounded like the single mother of her hopeful new charge, but at the same time, the mother had told her she was a bit of a handful, so she really didn't want to be stuck chasing a toddler around in the heat in anything too fancy.

She was pretty sure she'd gone too far in the opposite direction this time, though. She'd picked out a pair of black denim shorts, the pockets on the rear shaped like hearts and colored red, and a sleeveless pink button up, tie front shirt with a white lace collar, and a matching pink bow in her hair. She thought it looked pretty cute, and she shouldn't get too warm, even if the baby wanted to play outside, but she wasn't sure it would really impress the mother.

Unfortunately, she was out of time. She glanced over at the clock and gasped as she saw what time it was, hardly able to believe she'd wasted so much time looking for an outfit. She was just so nervous! She really wanted a good summer job, something other than flipping burgers, and this sounded like it could be that! Or would be, if she could get there on time now.

She had planned to drive, but now there was no way she could do that, so instead she just grabbed her bag of supplies, slinging it across her shoulder, and her wand and Apparated, praying that they hadn't put anything between their fence and garage since taking the picture they'd sent of their house. Thankfully, when the world snapped back into place around her, she saw that was, indeed, the case. Just walking up to the door didn't feel quite as mature as driving, but it would just have to do. She had wanted to leave her wand out in the car, though, because from her experience, kids always liked to play with it if they saw it in her bag, and that rarely ended well for her. She'd just have to keep a closer eye on it this time, she thought. Then, with a flash of brilliance, she decided to use a rather complicated little charm on it, disguising it as the most boring toy the viewer could imagine, making it so that she was certain the little girl would have no interest whatsoever in it, while still not looking out of place in her bag.

She marched up to the door and rang the bell, waiting patiently as she tried to think of the best way to introduce herself. Even if she was still pretty sure her outfit wasn't right, maybe a good first line would make a good first impression on her client. She smiled up at the woman who opened the door, surprised at how quickly she arrived. She still wasn't ready, so she froze for a moment, giving the woman a chance to smile at her and ask, "Are you lost, dear?"

Sierra shook her head with a blush. "N-No, I'm... I'm Sierra!" she declared, standing there awkwardly for a few seconds before deciding to clarify, "I'm the babysitter!"

"Oh, of course you are!" the woman said, standing aside. "Come on in! You're right on time!"

"Oh, good!" Sierra smiled, glad to hear that, after how worried she had been. "You have a very beautiful home, ma'am!"

"Thank you!" the woman replied. "You can go ahead and call me Lilly. And you're Sierra?" Lilly grabbed Sierra, holding her out at arm's length for a moment, looking her over thoroughly before declaring, "Yes, I can see that! Your references had some very... interesting stories about you!"

Sierra blushed as she wondered exactly what those stories were. She usually managed to get things at least mostly cleaned up before the parents got there, but who knew what the kids said after she left, and whether the parents believed them. "Good stories?" she asked hopefully.

"Interesting stories," Lilly repeated unhelpfully, though it became clear what she meant when she continued with, "I have to admit, I have some doubts about you."

Sierra bit her bottom lip nervously. Had she come here for nothing? "I really do know what I'm doing!" she promised. "If you just give me a chance, I..."

"Yes, I'm sure you'd be just fine," Lilly interrupted her flustered begging. "But this is a special case, and I just don't know if you're ready for it."

"I can try!" Sierra nodded. "You don't have to hire me for the whole summer right away!"

"Well, I wasn't planning on it, but thank you for the offer," Lilly patted her on the head condescendingly, making Sierra blush. "I do like that you came prepared. Let's see what you brought with you," she said, reaching out and opening Sierra's bag, starting to rummage through it. Sierra couldn't help but blush again as Lilly pulled the first thing out of the bag - her stuffed bunny, Ms. Hoppikins. "And who is this fine fellow?" she asked, her tone sounding more like she was asking a child than a potential employee. "Is he your friend?"

"Sh-She's just a toy," Sierra squirmed. "It's important to keep kids occupied, so I have lots of toys..."

"Yes, but the rest of these look like games," Lilly commented. "Do you not think the children would have stuffed animals of their own?"

"W-Well, yes, but..." Sierra stammered. "But..."

"Oh, don't worry, I'm just teasing," Lilly smiled, tapping Ms. Hoppikins's nose against Sierra's before shoving the stuffed animal into the girl's hand. "Hold this. I don't mind babysitters having friends over if they're as well behaved as this little lady. Let's see, Pampers, good, baby lotion, good, baby powder, very good... Zoe loves that! Hmm... No diaper rash ointment?"

Sierra blushed as Lilly turned her attention back from the bag to her. "I-I just thought, if I needed it, the parents would already have it," she said, feeling proud of having come up with that, considering she had really just not thought about it.

"And you didn't think they would have powder or lotion? It's always good to have extra, isn't it?" Lilly asked seriously.

Sierra nodded, biting her bottom lip and staring down at her feet, embarrassed at the oversight. But not nearly as much as the next one. "And no changing pad?" Lilly shook her head.

"What?! No, I have one!" Sierra declared, looking back up to dig through her bag, only to realize that the woman was right. "I thought for sure I'd put it in here!"

"But you didn't double check?" Lilly shook her head again, closing the bag up without bothering to take Ms. Hoppikins back, leaving Sierra holding her.

"I did!" Sierra responded back automatically. She usually did, but she'd been in such a hurry she hadn't had time.

"Did you?" Lilly demanded. Sierra nodded hesitantly. "I think you're fibbing to me, young lady. And I will not put up with that! Thank you for your time, but I will not be requiring your services!"

"No!" Sierra squeaked, seeing the woman reach for the door. "Please, give me another chance! I can do this, I swear!" She got down on her knees, begging, blushing as she realized she was still holding her stuffed bunny, now clasped between her hands in front of herself, before reaching up with her free hand and grasping at Lilly's skirt when she began to open the door anyway. "Please, I just lost track of time and didn't pack as well as I should have! I still know what I'm doing! Just give me another chance!"

"Hmm..." Lilly paused, doorknob half turned, before letting it go. "All right, one more chance. Let's see if you really are as good as you say." She reached down and took Sierra's grasping hand, helping her to her feet, but not letting go afterwards as she led the girl through the house, still holding her bunny. Lilly seemed to be taking large steps, making Sierra have to struggle to keep up, which only made her feel more silly as she made her way through the house after Lilly, until finally the woman opened a door and pulled her through it into the nursery.

But it wasn't just any nursery. Sierra's jaw dropped as she looked around at the place, trying to take it all in. Like most nurseries, it had a changing table, a crib, a rocking horse shaped like a lion, crib, and toy box, and smelled of baby powder, and just slightly of used diapers. What was strange about it all was the size, which was more than big enough for Sierra - Lilly probably could have used it all if she wanted! That made sense, though, since when Sierra looked past the bars of the crib, she saw not a baby, or a toddler, but another full grown woman, this one with pink hair, sleeping there in nothing but an obviously wet diaper, sucking on a pacifier.

"Standing there gawking is not a good way to start," Lilly teased, bending down to whisper in Sierra's ear before standing back up with a giggle as the girl jumped in surprise. "Come on, now, get out your diaper bag and show me what you can do!"

Sierra blushed at Lilly calling her bag of supplies a diaper bag as she took it off her shoulder, though she wasn't quite sure what to do from there. "Umm... How?" she asked, confused.

"Show me you know how to put a diaper on! Show me on your little bunny friend!" Sierra blushed again, this time at the memory of doing just that thing when she was younger, though she hadn't in quite a long time.

"O-Okay," she nodded, starting to walk over to the changing table.

Lilly stopped her in mid-step, grabbing her arm gently, but firmly. "No, no... You're just using the supplies you brought. Let's see what you can do with those, first."

"Umm... All right..." Sierra said, though as she stood there, looking around, she couldn't help but still feel overwhelmed, and a little scared. Should she really be there? After a moment, Lilly grabbed her arm again, this time pulling her over in front of the crib and pushing her down onto all fours. Sierra dropped her bag, sending stuff pouring out in all directions, surrounding her with baby supplies as Lilly patted her on the bottom.

"Get going now, Sierra!" she instructed. "Your baby is bound to have an accident if she isn't in diapers soon!"

Sierra's cheeks turned red as she quickly sat, settling her backside down in the soft carpet of the nursery to keep it out of Lilly's reach, embarrassed that the woman she was trying to impress had done that. "Y-Yes, Lilly," she nodded, looking around herself to find one of the Pampers, grabbing it and starting to unfold it. They weren't just any Pampers, of course... It was a good idea to have some spare diapers, just in case, but it was always hard to tell what size baby you would need them for, so Sierra had come up with an ingenious solution for that. She just enchanted one set of diapers so that they would automatically fit whoever they were intended to be put on at the moment. Nice and simple! She'd chosen Pampers because she thought their designs were the cutest the last time she'd gone diaper shopping. The first couple times she'd tried using diapers she'd enchanted that way had led to leaky diapers - she wasn't sure if she had just not been paying attention, or if the magic affected them somehow, perhaps stretching the padding out further than it could handle - so there was an extra spell on them that made them quite a bit thicker as well.

As Sierra laid the Pamper out, she failed to notice the girl in the crib starting to stir, slowly waking up and turning to watch her as she put Ms. Hoppikins in the center of it. She felt absolutely ridiculous, but this was what Lilly seemed to want, and she wanted to make the woman happy so she would hire her. She grabbed the baby lotion and pretended to squirt it out onto the bunny's crotch, then pretended to shake the baby powder there as well before pulling the diaper up between the toy's legs, taping it into place.

"There, see?" she said, glad to be done with the silly test. She started to stand up, but Lilly put a hand on her shoulder, keeping her down on the floor, holding out her other hand expectantly.

Lilly took Ms. Hoppikins as Sierra handed her up, shaking her head. "Bunny, do you think Sierra did a good job with your diapering?" Lilly twisted the toy's neck slightly, making it shake its head before using a slightly higher voice, bouncing the bunny a little with every word. "No way! She didn't use baby wipes, or rub in the lotion or powder! And just look at how loose the diaper is! I'd leak all over!" Lilly sighed dramatically, switching back to her normal voice to ask, "Do you think she's ready to be a babysitter?" before answering through Ms. Hoppikins with an emphatic, "No way!"

"You heard her," Lilly shrugged. "What do you think, Zoe? Do you want her to look after you?"

Sierra turned in surprise as the girl in the crib began to speak, blushing at the realization that her audience had been even bigger than she thought. "Nuh-uh!" Zoe said with a playful smile, as if she knew what was coming next.

"Well, that's two votes!" Lilly declared. "Of course, my vote is the one that matters, because I'm the Mommy. And, honestly, while I think it's just adorable that you carry diapers for your little friend here..."

"I don't!" Sierra protested automatically, pouting.

"Oh, don't you?" Lilly raised an eyebrow. "Do you take care of many babies the same size as your bun-bun here?"

Sierra bit her bottom lip, not really able to answer that. Of course she couldn't explain the spell that was on the diaper, and there really wasn't much else she could say except, "It's so the kids can play with her and dress her up..."

"I'm sure it is," Lilly said condescendingly. "And don't interrupt me! As I was saying, while I think it's just the cutest that you carry around your little bunny and a diaper for her so you can pretend you're a babysitter, you are obviously nowhere near ready for the real thing. In fact, I bet Zoe here is more capable, and she's just a baby! But, you know what? I'm still glad you came, cutie, because you gave me a great idea. Zoe, how would you like a practice doll, so you can practice diapering and feeding and taking care of a baby yourself?"

"That'd be lots of fun, Mommy!" Zoe exclaimed, bouncing in her crib. Sierra, still being held down on her knees on the floor, looked between her and Lilly nervously, having a bad feeling about the way the conversation was heading.

"It will be!" Lilly agreed enthusiastically. "Do you like this one?"

Sierra froze as Lilly's hand tightened on her shoulder, just as she tried to stand and get away. "But..." she tried to protest.

"Yay!" Zoe clapped her hands.

"We'd better get her into a diaper, then, huh?" Lilly smiled.

"No! I'm not a baby!" Sierra whined, trying to squirm free of Lilly's grasp.

"I'll show you how to do it this time, and then you can try when she needs a change," Lilly said, pulling Sierra to her feet and patting her bottom again. "I'm sure that won't take long!"

"You can't do this!" Sierra thrashed as the woman dragged her to the changing table, which, now that she saw it close up, she realized had a pair of cuffs attached to the sides, which Lilly easily pushed Sierra's wrists into, locking them into place before setting Ms. Hoppikins, still diapered, down beside her as she struggled. "Let me go!" she whimpered as Lilly walked back to the crib and let Zoe out, who eagerly hurried over to the changing table as Lilly bent down, grabbing a Pamper from the floor, then reconsidering and taking a second as well.

"It was so nice of you to bring such cute diapers!" Lilly said, setting them down on the changing table. "They look like they'll fit you perfectly! And they'll match your little friend's!"

"No!" Sierra blushed, glancing over at Ms. Hoppikins. Not only was she going to be put into a diaper, an actual baby diaper she had enchanted herself for her babysitting charges, it was, indeed, the same kind that she'd just put her stuffed animal in.

"These clothes aren't appropriate for a little baby, either," Lilly observed as she began to unbutton Sierra's shorts and begin sliding them down the girl's uselessly kicking legs. "We'll have to find something else for her to wear!"

"My clothes are fine!" Sierra insisted, face flushing as Lilly grabbed the waistband of her pink, heart-covered panties. "Especially my underwear!"

"She's awfully grumpy!" Zoe observed. "Maybe her tummy hurts! Should I go get the suppositories?"

"No!" Sierra squeaked, trying again to break free from the table.

"What a great idea! You're so smart!" Lilly smiled at her, kissing her on the top of the head. "They're in the bathroom."

Zoe scurried away, leaving her Mommy behind to finish undressing Sierra, sliding her panties down, then tickling the girl's tummy where her shirt had ridden up and exposed it. "You're so squirmy!" she teased, before starting to unbutton Sierra's shirt from the bottom, freeing her wrists from the cuffs just long enough to slide the shirt off of one of the girl's arms, and then the other, then starting to untie Sierra's sneakers.

"You can't do this! I'm not a baby!" Sierra tried to keep her feet away, but Lilly clearly had lots of experience with wrangling babies, and easily finished her job, casting Sierra's shoes, and then socks, aside, leaving her completely naked on the changing table, then starting to tickle the soles of the girl's feet, making her protests quickly dissolve into helpless giggles.

"You sound like a happy baby now!" she said, picking up one of the Pampers and unfolding it, just as Zoe returned with the container of suppositories. "What a good helper! I'm sure you'll take great care of your little dolly, won't you?" Lilly kissed Zoe's head again, setting the container down on the table. "Now, get close and watch how to do this!"

Carefully, Lilly showed Zoe how to cut slits in the outside cover of the diaper, then laid it out and grabbed a large booster pad from under the table and laid it out inside. Sierra gulped as she watched. Clearly, Lilly already planned on double diapering her... Did she really need to add even more bulk to the diaper?! "I don't need all that!" Sierra pouted, but the woman just slipped a pacifier into her mouth in reply and lifted the girl's feet into the air, sliding the diaper beneath her bottom.

"There we go! Now, we have to make sure she's nice and clean! She didn't make a messy this time, but she will next, so it will be even harder then!" Lilly explained as she grabbed a cool baby wipe, making Sierra squirm as she began to use it to thoroughly clean her, seeming to pay a little more attention than was really needed in some of Sierra's more sensitive spots.

"Stop it!" Sierra pouted behind her paci, squirming and blushing.

"Then, when she's nice and clean, you put on the lotion," Lilly instructed, squeezing the stuff directly onto Sierra's skin, making her squeal at the cold sensation. "You have to make sure you rub it in well!" she said, starting to do just that, massaging it into Sierra's skin very thoroughly, especially between her legs. "And now..." she said, trailing off expectantly.

"The baby powder!" Zoe giggled.

"Of course! Your favorite part!" Lilly agreed. "Why don't you try this?" She handed the baby powder over to the diapered girl, who eagerly twisted it open and began shaking it onto Sierra, quickly creating a cloud of sweet smelling dust that made Sierra cough while Lilly said, "You have to rub that in, too!" and she felt Zoe doing just that.

"Usually, you would just tape up the diaper now," Lilly went on once Zoe was finished, looking quite proud of herself as Sierra laid there, a little flustered and blushing, "but we can't forget about these!" She smiled and picked up the container of suppositories.

"Yes, you can!" Sierra tried to insist past her pacifier.

"Hmm..." Lilly speculated for a moment. "I wonder if we should take her temperature, too... Maybe she's cranky because she's sick."

Sierra shook her head, feeling pretty sure they wouldn't be using an oral thermometer for that.

"Maybe if she's still cranky after she fills her diaper," she decided finally, lifting Sierra's legs in the air, leaving her bottom fully exposed. "Now, do you want to be a big helper again?"

"Yeah!" Zoe nodded.

"Okay, take one of those suppositories, and put it into her bottom!"

"Nooo!" Sierra whined, staring helplessly as she saw Zoe gleefully grab one of the little white objects, then stare down at her backside.

"Where do I put it?" she asked innocently, though Sierra had a feeling she had done it mostly to see her blush some more.

"Right there!" Lilly told her, patting Sierra's lotioned and powder rear. "Just push it in!"

Sierra's cheeks turned bright red as she felt the girl's finger begin to push into her, slowly forcing the suppository inside her body, sliding it deeper and deeper, until Sierra could feel her body take ahold of it and continue the job, pulling it inside, no matter how much she tried to will it not to.

"Good job!" Lilly praised Zoe. "What a good helper you are! Do you think we should do another, just in case?"

"No!" Sierra yelped, but Zoe just nodded enthusiastically, repeating the procedure before her Mommy cleaned her hand with a baby wipe, and continued with Sierra's humiliation.

"Now, just pull the diaper up nice and snug, like this," she demonstrated, holding it tightly against Sierra's tummy, "and tape it up!" She repeated the procedure with the second diaper, then ran her finger along the leg gathers, making sure it was on perfectly, before patting the front of it. "And there we go! A perfectly Pampered little baby!"

"I'm not a baby!" Sierra wailed, squirming in her thick baby diapers.

"She's still awfully cranky," Lilly mused. "Maybe we should have given her an enema instead. Oh well, there's always next time! Now, I'm going to pick her out a more appropriate outfit... Why don't you blow some raspberries onto her tummy like Mommy does with you?"

"Okay!" Zoe nodded, and before Sierra could try to say anything, hoping that Zoe would be more reasonable than her Mommy, she was giggling helplessly, the tickling sensation of Zoe's lips on her belly almost making her forget about the already mounting pain in there. Zoe, seeing how effective it was, kept going, ignoring Sierra's half-giggled protests.

By the time Lilly returned, Sierra was laughing so hard she could feel her bladder dribbling into her fresh diapers, making it easy for Zoe and Lilly to pull a pair of rainbow striped thigh high socks onto her squirming legs. Lilly then unfastened Sierra from the changing table and sat her up, slipping what seemed at first like a shirt on over her head, tugging it down over her queasy tummy, then lifting her down onto the floor, and, almost before Sierra notice part of the shirt was dangling between her legs, had pulled those parts together and snapped them up, making Sierra realize it was a onesie. It was pink, with a butterfly pattern, and the crotch bulged quite a bit from the thick padding beneath, which it held quite snugly right against her body, no matter how she stood. Lilly shoved Ms. Hoppikins, with her matching Pampers, into Sierra's arms, and her outfit seemed to be complete.

"All right," Lilly said, sounding a little more serious as she turned to Zoe. "Now, it's your bathtime, so I'm going to go get it ready. I want your nursery all cleaned up by the time I come back, okay?"

"Okay, Mommy," Zoe nodded obediently. "Is Sierra going to take a bath with me?"

"No, not this time," Lilly shook her head. "I don't think she needs a bath just yet... But she will pretty soon!" Zoe giggled at that, while Sierra blushed and stared down at her feet, past her puffy crotch. "And if we wait, I can teach you how to give her a bath!"

Zoe pouted a little at that. "But I just learned... I wanna play with her some more first! I want to show her my rocking horse!"

"That's fine," Lilly nodded patiently. "You can give her her bath whenever you're tired of her stinky diapers... But you're getting yours now, so get to cleaning up!"

Zoe nodded, and started to pick stuff up off the floor, including the toys Sierra had been carrying in her bag, taking them over to her toybox and dumping them inside. Sierra stood there watching in a daze for a minute or two before remembering that one of those toys was her wand! That would get her out of this! Quickly, she toddled over to the toys, looking around at them and trying to spot it. "Here, you take this stuff over to the changing table!" Zoe ordered, shoving the rest of the Pampers Sierra had brought with her into her arms, along with her other supplies, piling more and more on until Sierra was struggling to keep ahold of it all, then swatting Sierra on the diapered bottom when she just stood there.

There was way too much stuff, especially when she was trying to hold on to Ms. Hoppikins as well, and she still wasn't used to walking in her thick diaper. By the time she got to the changing table, she'd already dropped half the stuff, and had to go back and collect it all, setting it on top of the table, then hurrying back over to the toys, only to see that Zoe had just finished putting them up, slamming the lid of the toy box with a loud bang. Sierra toddled over to it and tried to open it, a little surprised at how heavy it was, only to have Zoe slap her hand away anyway.

"Those are my toys!" she said with a huff. "I'm the one in charge, so I get to choose what we play with!"

"But I just..." Sierra protested.

"No!" Zoe declared loudly. "They're mine!"

Sierra squirmed, starting to suck nervously on her pacifier. Zoe didn't look like she was going to change her mind anytime soon, and without her wand, she wasn't sure how she was going to get out of here... Especially before something very bad happened in her diaper! And if she just left it up to Zoe, she wasn't sure if she would ever bring her wand out to play with it! She had enchanted it to look like the most boring toy the viewer could imagine, so why would she, when she had so many other toys to choose from?

Of course, Sierra thought, Zoe was about to be given a bath, something she was reminded of when Lilly returned, a towel slung over her shoulder. Zoe couldn't stop her from getting into her toy box if she wasn't there! There was some hope after all!

"All right, to the bathroom with you!" Lilly ordered, swatting at Zoe's wet diaper to send her scurrying away, giggling. "And let's make sure you stay out of trouble..." she said, grabbing Sierra and putting her into the crib, pulling the side up and locking it in place before following her baby girl out to the bathroom.

Sierra's eyes widened as she rattled the bars of the crib, tugging urgently on them, trying to figure out how to lower them again, to no avail. She groaned, pressing a hand to her bottom as her tummy rumbled, but she was barely able to feel it through the diaper. She sucked harder on her pacifier, staring up at the bars as she bouncing in place urgently, knowing she was very close to being out of time. She made a feeble attempt to climb out of the crib, but it ended just as badly as she thought it would, with her getting barely off of the mattress, and certainly nowhere near the top.

It wasn't fair! Her wand was right there! She could practically touch the toy box from the crib! In her desperation, she tried to do just that, reaching through the bars, stretching out her arm as far as it could go. She wasn't quite sure what that was going to do - the lid was heavy enough that she was pretty sure she'd have a hard time opening it even when she wasn't reaching out from so far away, and the wand could be way down at the bottom - but she felt like she had to try!

She was still trying when she felt another rumble in her tummy. This one was a little different, but she didn't realize it until it was too late, and her eyes went wide as it caused not a little gas, but a huge wave of squishy, stinky mush to push out into her diaper. She squeaked and squirmed, feeling the mess spread out into her diaper, being pushed up against her quite securely by the onesie, forgetting about the toy box as she hugged Ms. Hoppikins to her instead, cheeks bright red as she felt herself continue to fill her diaper, not able to stop herself no matter how hard she tried.

"This isn't fair!" she whined as she finished, stomping her foot angrily, though all that did was make the mattress beneath her crinkle. "It's not..." She gasped as she lose her balance, falling flat on her mushy butt, blushing bright red as the mess in her diaper squished beneath her bottom. It only made her feel more upset, and she began pounding her fists against the crib's mattress, pouting and whining while, in the distance, she could hear Zoe laughing and splashing in the bathtub.

What she didn't hear was Lilly saying, "It sounds like she's still awfully cranky! I think I'd better get the thermometer out after all!"

"Yeah!" Zoe agreed with a giggle. "And if that doesn't work, can you show me how to give spankings?"

"Of course!" Lilly smiled proudly at her baby girl. "You're such a good girl! I'm sure you'll take just the best care of your little dolly!"
