"I'm so sorry, Zoe," Sierra blushed, looking down at her feet. "I was just so busy, I didn't have time to find you something."

It was kind of true, but really, Sierra just had a bad track record when it came to birthday presents for the pink-haired girl.  She always tried to use to occasion to trick her or embarrass her, or make her realize how much of a meanie she could be. Now that she wasn't seeing Zoe quite as often, she didn't feel as much of a need to do that, plus she didn't want to risk another backfire like she'd gotten the last couple times.

"It's okay," Zoe told her, but Sierra could tell that she was a little disappointed.

"I-If you can think of something you want, then I can see about getting it for you!" Sierra offered. For as many times as Zoe had humiliated her, she really was a good friend, and Sierra didn't want her to be sad.

"Well," Zoe smiled, her expression immediately changing, making Sierra suspect she'd just been acting a moment before. "Could we play dress-up, like old times?"

Sierra squirmed, knowing exactly what that entailed. It was Zoe's birthday, though, and it was harmless, really. "For one day," she told Zoe sternly. "That's all!"

"Okay!" Zoe nodded, grinning. "But I get to choose the day!"

Sierra was a bit surprised. She'd fully expected Zoe to want to do it right away. She usually wasn't good at waiting for things that she wanted. "Umm, all right, sure," she shrugged, feeling a little nervous now. Why would Zoe want to put this off? "When?"

"We'll see," Zoe shrugged.

___________________________________________________________

The next weekend, Zoe invited her to go to the zoo. Sierra was certain this was the day Zoe was going to choose, so she made sure to leave her wand at home, but agreed to go. She felt anxious and blushy as soon as Zoe answered the door, but the girl just greeted her like nothing was strange, and the two of them went on their way. It was hard not to notice the abnormally large bag Zoe brought with her, though.

It was a lovely spring day outside, and Sierra had a great time running around the zoo, looking at all the cute animals, despite feeling nervous the whole time. Any moment, Zoe could tell her that it was time!

Sierra didn't want to give Zoe any excuses, so she did her best to ignore the mounting pressure in her bladder, but after lunch, and a big glass of yummy lemonade, she had to say, "I'll be right back!"

"Where are you going?" Zoe inquired.

Sierra blushed. She was sure Zoe knew, and just wanted to make her say it so that she could tell her no. It didn't make much sense for her to go anywhere else on her own, though. "The bathroom," Sierra sighed.

"Oh, I'll come, too!" Zoe exclaimed. Sierra pouted a little, but she had agreed, after all.

Zoe let Sierra go first as they followed the signs to the nearest bathrooms. Once they got to the little hut where the bathrooms were, Sierra headed towards the women's room. Zoe grabbed her arm and pointed towards the family bathroom entrance instead.

Sierra sighed, but went inside. Zoe followed her, pulling the door shut behind them and locking it with an ominous click that made Sierra jump. Unfortunately, since she'd already been feeling pretty jumpy before that, the latest start made her body do something else, and she couldn't stop the tiny gasp as she felt a trickle of pee leak out into her panties as she imagined Zoe putting her onto the changing table built into the wall here and diapering her up. She'd worn a longer dress today for fear of exactly that happening, but who knew what Zoe had brought for her to wear.

She hoped nobody had been watching them too closely. It was going to be bad enough walking around for the rest of the day in a diaper. Having someone watch her go in as a normal, if petite, adult, and come out as an oversized toddler would be even worse!

"What did you do, Sierra?" Zoe asked sternly.

Sierra felt herself slipping back into her usual submissive role much easier than she would have liked. "N-Nothing," she fibbed, tugging at her skirt. Zoe gave her a skeptical look, and Sierra knew what was coming. Her cheeks lit up even more in preparation, and she wanted nothing more than to sink into the floor.

"Fine!" she gave in after a long moment, lifting her skirt. "I had a little accident! Come on, let's just get it over with! What do you have?!" She grabbed at the bag Zoe had brought. Zoe let her unzip it, watching in amusement. There were some fresh diapers for the bigger girl, but, sure enough, there were some in Sierra's size, too.

"Let's just get it over with," Sierra pouted, grabbing one of the diapers out of the bag and shoving it at Zoe.

"All right," Zoe smiled, picking Sierra up and setting her down on the changing table. She pushed Sierra back, making her lie down and strapping her to the table, even though Sierra wasn't trying to get away any more than with her usual squirming. "These are so cute!" Zoe gushed as she pushed Sierra's skirt up, examining her damp panties with cartoon puppies dancing around on them. "It's too bad you went tinkle in them!"

Sierra blushed, tugging against the strap, more out of embarrassment than trying to escape. "Just get it over with," she whined.

"Why? Does somebody need to go even more?" Zoe teased. She turned the plain youth-sized diaper Sierra had picked over in her hands. "Well, then I don't think this will be enough." She slid the diaper under Sierra's bottom, powdering her up and taping the diaper up snugly before pulling a second one out of her bag. "We'd better double you up just to be safe, don't you think?"

"No!" Sierra whimpered automatically, before remembering her agreement. "Fine, if you think so," she sighed. Zoe grinned, making a few holes in the plastic coating of the diaper on Sierra before securing the second one in place. Sierra squirmed on the changing table, squeezing her thighs together and fretting over how much of a waddle this was going to give her.

Zoe wasn't done yet, though. "That ought to hold even a little fountain like you!" she exclaimed, giving the diaper a pat. "But they're so plain! I think we should spice them up a little!" She reached into her bag again, this time producing a Pamper. Sierra blushed, telling herself that, even though Pampers fit her normally, they surely wouldn't when she was already double diapered.

Unfortunately, she was wrong. It fit perfectly, covering the other two diapers and making it look like she was simply in the world's thickest Pamper. Sierra was all too happy to scramble down off of the changing table, groaning as she felt how far her legs were being pushed apart even just standing.

Zoe turned her around, then tutted. "Uh-oh, someone leaked on her skirt," she chanted.

"What?!" Sierra squealed. In an instant, Zoe had the skirt pulled off, and was showing the back of it to her while she stood there in the bathroom with nothing covering her huge triple diaper. There was a small wet spot there, but it probably wasn't big enough for anyone to notice unless they were looking.

"Good thing I brought a spare," Zoe grinned, reaching into her bag to pull out a much shorter skirt. It was a pleated, red plaid skirt, and Sierra had no doubt that it would be a constant struggle to keep her diapered covered in it. She had agreed, though, so she sighed and let Zoe put it on her and prove her right.

"Perfect!" Zoe clapped, looking down at her handiwork. "Now, I need a change, so entertain yourself for a few minutes." She began to dig through the bag again for her own diaper.

"Do you want me to help?" Sierra offered helpfully.

Zoe just giggled and asked, "You?" as she patted Sierra on the head condescendingly. "I think I can handle it."

Sierra blushed, tugging at her skirt as she watched her reflection in the mirror. The bathroom stalls were mere feet away, but she knew she wasn't going to be using them anytime soon. She sighed and squirmed, trying not to be too obvious as she let her bladder go. She'd come in here to do that, after all, and at least there was some privacy. She was a little surprised at how much she needed to go, as her diaper kept filling more and more, the padding swelling up even more as she kept peeing.

She should have known better than to think she could fool Zoe about this. As soon as Zoe had her own diaper changed, she hopped off the table and pressed a hand to the crotch of Sierra's diaper. "Wow, you had to go that much again already?" she giggled.

"I barely went before!" Sierra fumed, wanting to point out that her panties had barely been wet. Then again, that meant admitting out loud that she'd peed them, plus, it had been enough to get her skirt wet, if even just a little.

"Well, I must have forgotten how much you go," Zoe said. "I thought those diapers would be plenty, so I guess you'll just have to stay in them for the rest of the day."

"What?!" Sierra whined, pouting. They already felt soaked, though she knew that was probably just the first layer. Was she really going to have to spend the rest of the day toddling around in them?!

"Sorry," Zoe grinned, not looking like she meant it at all. "Come on, I think it's almost time for the elephants to get fed!"

The rest of the day was still fun, even if it was impossible to forget that she was diapered, and pretty obviously so. Every time she saw someone looking strangely in their direction, she blushed and tugged at the skirt, sure she'd been moving too quickly trying to keep up with the taller Zoe, or that maybe her last little accident had made the diaper swell enough to be visible no matter how much adjusting she tried to do.

"Happy Birthday," Sierra blushed as they got back to Zoe's house, and she let the girl change her into a fresh diaper at last for her trip back home.

"What?" Zoe furrowed her brow. "My birthday was days ago, silly!"

"Yeah, but this was your present," Sierra felt just as confused as Zoe looked.

"I'm supposed to choose when I get that!" Zoe insisted. "You're the one who demanded I diaper you!"

Sierra tried to protest, only to blush and stammer uselessly as she realized Zoe was right. Maybe the girl had been planning on forcing her into those clothes, but Sierra had jumped the gun. "But I still..." she whined.

Zoe sniffled. "A-Are you going to take my present away?"

Sierra sighed and shook her head. "No, I guess not," she said.

________________________________________________________________

"Hey, do you want to go shopping?" Zoe asked her a few days later.

Again, Sierra was suspicious. "I guess so," she said, seeing as she didn't have anything better to do. She left her wand at home again. Zoe always did love to play with it when she could, and Sierra had no doubt that she would do so if she found it in Sierra's old clothes after dressing her up. Zoe with a wand never led to good things, so it was best to keep it as far away from her as possible.

To Sierra's surprise, Zoe didn't bring a diaper bag with her this time. The trip seemed pretty normal as the two of them wandered around the store, looking at clothes and toys and various other junk they didn't really need. Sierra almost suspected that she'd just been acting paranoid when Zoe steered their cart into the baby aisle.

"See anything here you need?" she teased.

"Zoooe," Sierra pouted, fidgeting as she eyed the packages of baby diapers, all lined up and staring down at her.

"Go on, pick them out!" Zoe urged. Sierra sighed, searching for what would be the least embarrassing ones. Unfortunately, since it was the baby aisle, the relatively plain youth ones were nowhere to be seen, nor were Goodnites, which were still babyish, but at least a little thinner.

"Don't be silly," Zoe told her as she grabbed one and quickly returned to the cart. "You know you need the nighttime ones!"

Sierra sighed and reached into the cart to pull the package back out, returning it to the shelf and returning with a pack of overnight diapers instead. She trailed behind Zoe as the girl began pushing the cart back through the store, but that turned out to be a bad idea.

"Are you tired, sweetie?" Zoe asked. Before Sierra could answer, Zoe had picked her up and set her down in the shopping cart's baby seat. It was a bit of a tight fit, though not as much as Sierra would have liked.

"I can walk!" Sierra insisted, cheeks burning as Zoe steered her through the store, hoping nobody was looking at her, and then down at the package of diapers in the cart behind her.

Zoe took her time, looking at every flavor of baby food and asking Sierra if she liked it or not, going through the baby clothes section and commenting on how adorable Sierra would look in the outfits, and then heading back to the baby supplies to pick out a pacifier, opening it right then and there to shove it into Sierra's mouth before they went to the checkout.

"I am so sorry I had to open this!" Zoe gushed to the woman running the cash register. "She just wouldn't stop fussing until I did! She's still Mommy's little baby, isn't she?" Zoe teased, tickling Sierra's tummy while the girl sat there in the cart, pouting. Sierra couldn't help but giggle and wiggle, unable to escape.

"Enjoy it while it lasts," the cashier advised. "They grow up all too soon."

"Not her," Zoe told her in a fake whisper. "No matter what I try, she just won't stop wetting her pants! It would be frustrating if she didn't look so cute in those!"

Sierra blushed as she watched the cashier pick up the package of diapers. "Oh, these are for you?" she smiled at Sierra. Sierra looked down at her dangling feet until the cashier reached over and tickled her, too, making her squeal in laughter again.

"I'm surprised they fit a big girl like you!" the cashier teased, her tone making it obvious she didn't think Sierra was all that big at all. "But I'm sure you'll be out of them when you're ready, huh?" Sierra, unsure of what else to do, nodded. The cashier chuckled. "I'm sure she does look cute," she told Zoe.

Once Zoe had everything paid for, she pushed the cart over to the restrooms, and finally let Sierra out. Sierra looked up at Zoe worriedly from behind her pacifier as the girl took her hand, leading her into the bathroom, and then to the handicapped stall.

"That cashier was so nice," Zoe said. "I think you ought to show her exactly how cute you do look in these, don't you think?"

Sierra sighed and blushed, wanting to say no, but remembering her agreement. "Fine," she pouted, letting Zoe diaper her up, then lead her back to the cashier. She gave Sierra a pat on the padded bottom to urge her forward, and Sierra nervously approached the woman. She tried to stay far enough away that she wouldn't notice her until she was done with her line, while still keeping Zoe happy. Unfortunately, the woman turned almost immediately.

"Oh, hi, there!" the cashier smiled down at her. "What are you doing, sweetie?"

Sierra glanced back over her shoulder at Zoe, then, red-faced, pulled the top of her shorts down. "Oh, look at you!" the cashier gushed, bending down to give her a hug and a tickle. "What a little cutie you are!" Sierra quickly zipped her shorts back up, hoping that not too many people in the line had seen, or that the bulge wasn't too obvious as she waddled back over to Zoe and left the store.

_____________________________________________________________________

Sierra showed up at Zoe's place bright and early the next Saturday, trying not to look too excited. It had been a while since she'd gotten to do an Easter egg hunt, and even though it was kind of a silly thing to look forward to, she really was.

"Am I really that early?" Sierra asked as Zoe answered the door and Sierra saw that nobody else was there. She hadn't thought she'd let herself get that over-eager about this!

"No, you were supposed to show up first," Zoe informed her. "We have to get you dressed up!"

"Huh?" Sierra's eyes widened. "H-How so?"

"You don't get to ask that," Zoe booped her on the nose. "This is my present, remember?"

"B-But... What about the store?" Sierra whined, before realizing, "You didn't actually tell me I had to do that, did you?"

"Nope!" Zoe giggled. "But that cashier was glad you did! Now, come on!" She grabbed Sierra's hand, leading her back to her nursery. She had a few things laid out, but not nearly as many as Sierra would have liked.

"You're cheating!" Sierra pouted, fidgeting nervously as she looked at the clothing. "This isn't fair!"

"You promised!" Zoe reminded Sierra as she started to undress the girl. Sierra was grateful that she'd thought better of bringing her wand today, either, just because some of Zoe's more troublesome friends might try something with it if they spotted it. She could hear them starting to arrive and being greeted by Zoe's Mommy. "Besides, you have a very important job today!"

"What is...?" Sierra started to ask, before Zoe shoved a pacifier into her mouth. She pulled the strap on the pacifier tight around Sierra's head, locking it into place. Sierra frowned, wrinkling her nose as her tongue began to feel strangely numb and stiff and hard to use, even if the pacifier's bulb wasn't in the way. Sierra was sure there was something wrong, but there wasn't a lot she could do about it.

Zoe quickly put Sierra into the rest of the outfit, before pushing the girl in front of the mirror. The pacifier-gag had a bunny nose and mouth painted onto the front, complete with whiskers and two little bunny teeth. Below that, she had a bib in the shape of a carrot, and nothing else. The bib was pretty big, covering up Sierra's breasts, but she still blushed, seeing how exposed she was. The bib hadn't looked big enough for that when she'd first seen it, and her chest had the same, odd tingling feeling as her tongue, and other places.

Like her hands, which were covered in a pair of fingerless white mittens. The palms were decorated with large pink circles, and smaller circles above those, in the shape of bunny pawprints. Moving downward, she had on, of course, a huge, thick white diaper, with a fluffy tail glued on the back.

She frowned as she looked at that in the mirror, squirming and blushing as she felt that, just like the reflection seemed to show, the diaper really was already damp. She didn't remember going at all! She gulped, glancing down at her feet, and the pink Mary Jane booties on them, decorated with tiny bunny ears and little bunny faces.

It was all cute, sure, but she was sure there was something more to it all. Everywhere the clothes were touching had that strange feeling, making them seem not quite right. She felt clumsy just shuffling her feet back and forth, and as Zoe handed her a fuzzy Easter basket in the shape of a bunny's head, she had even more trouble holding on to it than she should have with the fingerless mittens.

"Perfect!" Zoe giggled. "She told me you'd look adorable, but I didn't expect this!"

Sierra's eyes widened a little at 'she', and she tried to mumble the question of who Zoe was referring to from behind her pacifier.

Luckily, Zoe seemed to know what she was asking. "Your little friend sent me all this! Wasn't that nice of her? She told me it was all made special for you!"

That didn't really answer Sierra's question, so she mumbled again.

"Now," Zoe went on anyway, as if she didn't hear, "your job is to find as many Easter eggs as you can!" Sierra furrowed her brow. "I know, that's what everyone's trying to do at an Easter egg hunt, but it's especially important for you!" She reached over to the changing table to pick up the last piece of clothing on it. "She said I was only supposed to put this on you once I'd explained that."

Sierra frantically tried to speak again, starting to get very worried about all of this.

"Well, if you must know why," Zoe giggled, "it's because every egg you find will let you undo the spell on one piece of clothing, but only one! Oh, and you'd better hurry, too, because the spells only get more powerful the longer you're wearing your outfit."

Sierra's eyes widened as she frantically reached up, trying to clumsily undo the pacifier gag. Zoe tapped her on the wrist, just hard enough to make her stop. "Bad girl! No cheating!" she told her sternly. "That's only going to make the spells more powerful, anyway! Now, stop messing around, or everyone else will find all the low eggs before you can get out there! Unless you think you're still coordinated enough to climb up and get the higher ones?"

Zoe smiled, watching Sierra squirm, knowing that her feet were already feeling awfully klutzy. "Of course, if you can't find any, I guess I'll just have to take care of you, huh? Don't worry, we'll have lots of fun! We can play dress-up every day! Now, let's finish up your outfit!"

She raised the last piece of clothing, then paused for a moment. "Oh, what else was I supposed to tell you? Right! Samara says Happy Easter!"

With that, she slid the headband over Sierra's golden hair. A pair of white bunny ears with pink lining stuck out from the top, with a pink bow on one of the ears. Instantly, almost before Sierra could begin to worry over how far the spells her old classmate had put on these clothes would go, her brain began to feel fuzzy, making it difficult to concentrate on any one thought, especially of something like her old school. She wasn't old enough to go to school anyway, was she? She wasn't sure anymore, and just thinking about it made her head hurt.

"Come on, let's go!" Zoe encouraged her, holding out a hand.

Sierra grabbed it with one mittened hand, nearly dropping her basket as she waddled across the nursery floor, tripping over her own feet several times as she felt her diaper grow warmer between her legs as more pee-pee dribbled out with every step, and she tried to remember what Zoe had just told her she was supposed to do. It was very important... Wasn't it? Oh well! She was sure Zoe would let her know if it really was.

Zoe grinned as they walked out to join the rest of the hunt, softly singing to herself, "Happy birthday to me..."
