"Please?" Sierra pouted, batting her eyes as she stared up at Lilly, her hands clasped in front of her chest. "I'll be a good girl, I promise! I'll do all the chores for the rest of the month, even Zoe's!" It seemed like a pretty safe gamble, since Zoe usually made her do her chores anyway.

"I don't know," Lilly still shook her head. "After the way you behaved while Robin was here, I don't know if you deserve any special treatment."

Sierra forced herself to stay quiet and not mention how all of that hadn't been her fault. "But it isn't for me!" she explained. "I just want Zoe to have a happy birthday, and I know you're so busy you don't have as much time to work on planning her party! But I can do it!"

"That's an awfully hard job for a baby like you! I don't know if I can trust you with all that," Lilly said.

"I can! I'll try my hardest, I promise!" Sierra promised.

Lilly's eyes narrowed. "Is this a plan to make sure you're allowed to come? Because even if I did say yes, you'd still have to be a good girl until then."

"That's fine!" Sierra nodded. That suited her just fine, in fact! She wasn't sure she even wanted to meet Zoe's friends, not while she was the baby doll of the family. "I just wanna help! I want her to have the bestest birthday!"

Lilly smiled, her resistances melting. "It's nice to see you finally getting along with her better! All right, you can be in charge of the entertainment, but don't let her know about it! You have to keep it a secret!"

"I will!" Sierra agreed. She was very good at keeping secrets! After all, she'd never let Zoe or Lilly know that she was really a witch, or that their last babysitter had been an evil inter-dimensional robot, who she was still trying to convince Lilly to use again, since the last time she'd been there, she'd stolen Sierra's wand! She also didn't tell Lilly how over-zealous Zoe was with using the paddle she'd stolen from that same babysitting robot, or how, since getting it, Zoe had been looking for any little thing to punish Sierra for, but that was mostly because Sierra knew Lilly wouldn't listen.

But Sierra had a plan. She felt a little bad about it, especially doing it on Zoe's birthday, but, at least until she could get her wand back from Robin, this was her best bet. Any qualms she had about it were quickly quashed when she toddled back to the nursery and Zoe immediately ordered, "Come here, baby Sierra!"

Sierra sighed and marched to the bigger girl, blushing as Zoe's hand pressed against her diaper. "Not wet at all? What a bad baby! I think you need a spanking!"

"What?!" Sierra gasped. "B-But you spanked me last time because I did wet my diaper! That's not fair!"

"Aww, that's because you should have asked me for a change so you didn't get a rash," Zoe said, stroking Sierra's hair. "Now I'm afraid you're holding it too much and hurting your little bladder! I just want what's best for my baby doll! Now get to the spanking chair right now, or I'm taking that diaper down first!"

Sierra sighed, sulking over to the chair, where she saw the heart shaped paddle already laid out. She had no doubt Zoe'd had this planned out already, and probably would have spanked her either way, though this time Sierra had a plan. It was a little scary just how easy it was for her to let go as she walked, feeling her diaper's padding grow warm and wet around her as she moved.

"See?" she pointed out as Zoe strolled to the rocking chair and sat down with a grin. "I did it!"

Zoe reached out to check her again, but instead of being happy, she just shook her head. "Look at how wet you are! Obviously you were holding it too much! And you wet yourself just to get out of your punishment? I think you need even more of a spanking! Such a bad girl!"

"N-No fair!" Sierra stomped her foot angrily. "What was I supposed to do?"

"You're supposed to be the perfect little baby," Zoe informed her. "I didn't think it was that hard, but obviously you need all the help you can get! Now lie down and ask nicely for your spanking, or I'll send you to the corner after!"

But Sierra found herself in the corner a few minutes later anyway, trying to rub her sore backside through her thick diapers, because she hadn't been quick enough. Sierra had thought it was bad living with the Cases, but by now she was pretty sure that Zoe was even brattier than Madison. And unlike Madison, Zoe was really an adult, which made it all the worse, but also meant that she didn't feel nearly as bad as she planned her revenge.

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

"If you're grumpy because of this later, you'll finish your nap then, and I'll be taking over," Lilly warned Sierra, holding a cell phone just out of the girl's reach.

"Okay!" Sierra nodded, feeling exhilarated at just the idea of having been allowed out of her crib partway through naptime. "I don't need a nap anyway!"

"We'll see about that," Lilly said skeptically. "You're always fast asleep when I come in to wake the two of you up."

"There's nothing else to do," Sierra mumbled defensively.

"Of course there isn't!" Lilly smiled. "Babies need their rest. But since you're doing something nice for your sister, maybe you can do without it this once."

"I can!" Sierra promised, and finally the phone was lowered into her waiting hands. She started to walk away, but Lilly grabbed her arm.

"Where are you going?" she asked.

"I'm going to make some calls," Sierra answered, a little confused. That had been the whole plan!

"And why can't you do that in here?"

Sierra gulped, fidgeting in place. She hadn't prepared an answer for this! She hadn't thought she would need to! She probably should have, since she never got any privacy any other time, but she had just assumed that came along with the territory in this job. But the more she thought about it, the more she realized there was no reason Lilly couldn't listen in... At least, not if she was just doing what she claimed.

"I-I just, I want this to be a surprise!" she sputtered after a moment. "To both of you!"

"It isn't my birthday, though, sweetie," Lilly told her. "And I'm the one who's going to have to pay for it."

Sierra's stomach fell. She should have known this was too easy! Her plan was nearly complete, but now it was all falling apart, and she might wind up actually having to plan a real party for Zoe! "I-I can pay for it!" she offered. "I'm gonna do Zoe's chores for a month anyway, so I can just use my allowance from that! A-And I can keep doing them for as long as it takes to pay!"

Lilly smiled. "You're doing those chores to be allowed to do this, though, silly, not to get paid! Besides, Zoe is already getting paid for them, whether you or she does them! That's her allowance!"

"But if I'm doing them, shouldn't I get an allowance, too?" Sierra pouted.

"Allowances are for big girls like Zoe, so she can buy fun things for herself at the store, not little dollies like you," Lilly said.

"That's isn't fair!" Sierra whined before she could help herself, stomping her foot. In no time at all, Lilly had snatched the phone back and was reaching out to grab Sierra's arm again as well.

"I had a feeling this was a bad idea," Lilly shook her head. "Come on, back to naptime."

"No, I'm sorry! You're right!" Sierra agreed hastily. "I can do it out here! I-I just wanted you to be proud of me at the party when you saw how good I did!"

Lilly gave her a suspicious look, while Sierra sniffled and squirmed pitifully. She wasn't sure if it would work on the woman or not, but after a few moments, she handed the phone back over. "All right, you can stay here. I'll go work in my office. You have to be back in the crib before naptime ends, though! And you'd better wet your diaper before then, too, or Zoe will get suspicious!"

Sierra's face turned bright red, and she declared, "I'm not always wet after my nap!", but Lilly was already out of the room. It was true that she had been waking up wet, both from naps and nighttime, even more often than usual, but it wasn't all the time! She'd had occasional troubles for a long time, but she just wore Goodnites to bed, and more often than not, when she woke up, they were dry. But here, she didn't have any choice. She had to wear diapers to bed, and everywhere else, and, try as she might, she couldn't recall a single dry morning in the past couple weeks.

It wasn't her fault, of course! Zoe always felt the need to force feed her way too many bottles before bedtime, and she wasn't allowed out of the crib once she was put to bed, so she didn't stand a chance! Zoe was actually into this stuff, and there had been mornings when Lilly had pointed out that she was dry, but not Sierra. As much as the thought mortified her, she was now a bona fide, undeniable, bedwetter!

She couldn't blame it all on Zoe, but that felt much better than blaming it on herself, or just accepting that she was losing control that way, and it helped strengthen her resolve for what she was about to do. Her sore bottom helped with that, too.

She wasn't even sure if the listing she'd found in the yellow pages would still be active. She didn't know how old that copy of the phone book had been, though it was old enough to have lost its cover, and a few of its pages. Part of her almost hoped she would get a wrong number. Even if she didn't, there was no guarantee this would do any good. This guy might just be a fake, or rather, a normal Muggle.

If not, though, that might be even stranger. She'd always heard that hypnotists, at least the 'good' ones, were often wizards with a very particular power. Whether that power was too weak, or too specific, for Ilvermorny, Sierra didn't know, but they rarely showed up at the school. She'd also heard it was because they were too dangerous, but she wasn't sure she believed that. If that was the case, wouldn't that make the teachers want to bring them in all the more, to teach them control? Of course, it was always possible that their 'powers' weren't magic at all and that had just been a silly rumor.

Either way, she felt a little strange as she pulled out the phone book and flipped back to that page. She paused for a moment, staring at the ad, then dialed the number. The phone rang twice, then, before she could decide if she was glad or not that nobody had picked up, it was answered.

"H-Hello?" she said quietly into the phone. "Mr. Hadalis? O-Oh, I'm sorry, Dr. Hadalis? Hi... Yes, I was just wondering if you happened to do birthday parties. I have some special requests for the birthday girl..."

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

"There!" Zoe declared, spinning around in front of the mirror one last time to take in her pink party dress. With its tulle skirt and the huge bow at the waist, it clearly looked like it was designed for a toddler, but that didn't phase her one bit. "Now, let's get back to you!"

Sierra had actually been pleasantly surprised. She wasn't sure what Zoe would make her wear to the party, and it could have been anything, really. What it turned out to be was a white dress with pink trim, covered in a balloon pattern, along with a matching hair band with a couple of the same balloons along one side, replacing Sierra's usual hairbow. She was in a diaper as well, of course, and unlike Zoe's dress, hers was short enough to show off the bottom of it, but it was still more covered than she had anticipated.

"It's all right," Zoe mused, giving Sierra a good look. "I think something's missing, though! Now, what could it be? Does your bottom need some fresh redness to poke out from under your diaper? Or do I need to give you something to make your diaper droop a little more under your skirt?"

"Zoe, please," Sierra whined. Even though, with some luck, relief was in sight, she didn't want to go through either of those, especially with Zoe's friends on the way.

"Excuse me?" Zoe raised an eyebrow.

Sierra sighed. "Birthday Princess," she tried not to roll her eyes at what she had been ordered to address the other girl as that day, "please don't."

"It's my birthday," Zoe reminded her, as if she wasn't already aware. "I can do what I want with any of my toys, especially my dolly! And if she's going to be all sassy, then maybe she ought to have both!"

"I'm sorry!" Sierra squeaked.

"You will be," Zoe smiled. "Go fill up the enema bag for me! And make sure its completely full, or you'll have to refill it once its in!"

"Zo- Birthday Princess, please! Don't make me! I'll fill my diaper in front of everyone!" Sierra gulped.

"Aww, sweetie! THat'll be half the fun!"

"Please don't..!" Sierra started to beg.

Luckily, she was interrupted by Lilly's voice. "Come get the door, Princess! Your friend is here!"

Instantly, Zoe was distracted, grabbing Sierra's hand and dashing out of the room and through the house. Sierra was glad the other girl's mind was off of punishing her for a moment, but at the same time, she couldn't help but worry who was going to be at the door. She let out a little sigh of relief when it was Laura on the other side of the door and not Abby.

"Happy Birthday, Zoe!" Laura said as she stepped inside, giving the birthday girl a hug, then glancing down at her feet bashfully as she handed over a gift bag. "I got you this. I hope you like it! I can always return it if..."

Zoe grabbed the bag and immediately pushed aside the tissue paper, pulling out the onesie inside. "This is great! Thanks so much!" she grinned, hugging Laura again before sliding the garment back inside the bag and replacing the packaging as well as she could. "I'm supposed to wait until after cake to open presents," she explained quietly, shoving the bag at Sierra. "Go put this with the others!" she ordered.

"Hi, Sierra," Laura said shyly.

"Hi," Sierra blushed, all too happy to do as she was told. If Zoe was distracted with her friends, then she couldn't punish her! And once the day was over, Sierra shouldn't have to worry about punishment from her ever again!

"So, are you wearing?" she heard Zoe ask teasingly as she headed towards the living room, looking back to see her grabbing at the hem of Laura's yellow dress while Laura blushed.

Sierra set the bag on the table with Zoe's other presents, standing there for a while, rearranging them all, trying to act like she was busy. All she could think about was what she hoped would happen very soon now. She'd had her doubts at first, and she still wasn't entirely convinced Dr. Hadalis could do all he'd claimed, but after actually talking to him, she felt much better about her whole plan. It had been much easier to talk to him than she'd imagined, and she had wound up doing so much more often than she had anticipated. Lilly hadn't been happy about it, but the more she'd thought about it as the days leading up to the party wore on, the more things she thought of to add to her own little present to Zoe. Just thinking about it, she almost wanted to call him again, but he was probably already on his way by now.

She was so caught up in her thoughts, she didn't hear the others enter the room, or notice they were there until she felt something whiz towards, and then over, her head. A second later, something tightened around her body, pinning her arms to her side and pulling her backwards, making her fall onto her padded bottom.

"See? I told you I could do it!" Sierra's stomach sank at the sound of Abby's voice. That girl was such a troublemaker! She always seemed to be coming up with something new to talk Zoe into trying, more often than not on Sierra. Sierra glanced down to see the rope that had been lassoed around her, then back at Abby, advancing towards her in her denim shorts and blue shorts.

Sierra grunted as Abby pushed her forward onto her tummy, the rope quickly wound around the rest of her body, tying her feet and hands together behind her back and leaving her lying there, hogtied and helpless. "See?" the black haired girl said, patting the seat of Sierra's diaper. "Easy as that! Now you can do whatever you want with her!"

"I can do that anyway," Zoe bragged, kneeling down in front of Sierra. "Look at all this cool stuff Abby got me!" she squealed, clearly trying not to be too loud so Lilly wouldn't interrupt and find that she had already gotten into her presents. "You were so worried about making a mess in your diaper in front of everyone, but I bet this will help!" she said, pulling out a large butt plug and showing it to Sierra. "Watching you squirm will be so fun! And if that gets boring, we can just take the plug out, and that should liven things up! And we can always use this if you whine too much!" She held up a locking pacifier gag for a moment, then went back to digging through the contents of her present. "Oh, or this would be fun! It isn't meant for a baby like you, but maybe I'll be nice and let you try it out! Ooo, or this!"

Sierra was saved from Zoe's various new devices by the sound of the doorbell ringing and Lilly shouting, "You girls play! I can answer it!" Quickly, Zoe began shoving everything back into the large gift bag, pushing it into place with the rest right as Lilly walked into the room with Robin.

Apparently Robin hadn't yet figured out how to repair the damage Sierra had done to her cheerleader form, the one that she had used to babysit Zoe and Sierra a couple weeks prior, because she was still in her slightly older nurse guise, and carrying a pair of bags. "Happy Birthday, Zoe! My sister is so sorry she wasn't able to make it, but she sent this!"

Zoe retrieved the bag, clearly tempted to peek inside but not daring to with Lilly right there. "Thank you!" she smiled as she put the bag down, untouched.

"And I brought something for Sierra, too!" the disguised robot exclaimed, much to Sierra's surprise. "My sister told me you were running low on her Pampers, and they seemed like an unusual size."

"They are!" Lilly shook her head. "She just refused to tell us where she got them, and the ones we found fit, but they were just too leaky!"

Robin smiled. "Well, my sister has all kinds of extra baby supplies, and she found some that she thinks are the right size, so she sent them over!" she said, setting the second bag down. From her vantage point on the floor, Sierra could see that there were several packages inside. Obviously, they couldn't be the same as the Pampers she'd brought here initially, since she had enchanted those herself, but she had a feeling they weren't ordinary diapers.

"Isn't that nice of her? What do you say, Sierra?" Lilly asked, crossing her arms.

Sierra squirmed, blushing slightly as she realized neither of the 'adults' had mentioned anything about her being tied up, certainly not to tell Abby or Zoe to untie her. "Th-Thank you," she made herself say. Hopefully, with Robin here, she could find a way to get her wand back as well and get out of here altogether. That had been her hope, anyway, when she'd suggested that they invite Robin. Lilly had been sceptical, since in her mind they were inviting the cheerleader, who had apparently skipped out on the babysitting job partway through, but Sierra had insisted. Any spare time she had she spent practising her wordless spells, especially Accio.

Getting away now might almost make all the time she spent working on her plan with Dr. Hadalis seem pointless, but at the same time, there was no guarantee that everything would fall perfectly into place. This way, if anything did go wrong, she would at least have Zoe under control. And even if she got to go home after today, it would still be fun to get a little revenge, even for just a day. Not to mention that Dr. Hadalis's 'performance' might give her the perfect chance to pull off what she needed to do. Hopefully everyone would be distracted by that, giving her time to slip away to somewhere private and summon her wand to herself, right from within Robin's mechanical pocket, assuming she still had it there.

Her blush deepened as Lilly walked over to her, taking her position as an excuse to check her, sliding her fingers into her diaper and declaring, with more surprise than Sierra thought was warranted, "She's completely dry now! But don't worry, I'm sure she'll need a change before long, and then you can let your sister know how well they work out!" To be fair, it was impressive that Sierra had lasted that long, but she had been working extra hard lately to put off using her diapers as long as she could. She had no choice but to use them eventually, but she was trying to train herself to hold it better again, as much as she was able, though she hadn't made any progress with being able to do the same at night again yet.

"Sounds good!" Robin smiled, bending down to pat Sierra's diaper. In that close proximity, Sierra was sure she could feel the presence of her wand just inches away, all but confirming in her mind that the robot still had it on her. "Did you hear that, cutie? You'll be back in your precious Pampers in no time!"

With Lilly lurking overhead, Sierra had little chance but to give a falsely enthusiastic, "Yay," while she resolved to work extra hard to keep her pants dry. At the very least, she was glad that she was the center of attention for the moment to keep Robin from sending one of her little tentacles into her diaper to fill it with her diaper rash goop.

"Would you mind helping me out in the kitchen?" Lilly asked, leading Robin back out of the room, instructing the girls, "Play nice!"

"Yeah, play nice," Sierra pouted, glaring up at Abby. "Let me go!"

"Hey, why don't we go play in your nursery?" Abby suggested instead. Zoe seemed to think that was a good idea as well, but before they could leave, more guests began to arrive. Sierra, still tied up, could only watch as they arrived, blushing as they walked up to the table to put down their gifts, with no way to keep them from seeing her there, her dress pushed up to completely expose the back of her diaper.

It wasn't a huge party, but there was a small crowd by the time they all arrived, some of which Sierra recognized, some that she didn't. She wasn't sure which was worse to see, although she felt especially embarrassed when Elizabeth made her trip to the present pile. With her purple hair, and her gorgeous, ornate dress, Sierra had always found her to be very elegant. So, of course, it seemed like any time she was visiting, Zoe went out of her way to make Sierra look as silly and babyish as possible.

Finally, with everyone there, Lilly came back into the room, carrying a large chocolate cake, candles flickering on top, Robin beside her juggling several containers of different flavors of ice cream, and starting to sing 'Happy Birthday' to Zoe, the rest of the room quickly, and enthusiastically, joining in. Sierra glumly added her voice while she squirmed on the floor, her bladder starting to ache, just in case Lilly or Zoe happened to look over at her and saw her not participating. Zoe hurried behind Lilly as the woman set the cake down, blowing out the candles and waiting impatiently for Lilly to cut her a slice.

"Shouldn't you let Sierra out so she can have some cake?" Lilly suggested as she slide the plate over towards Robin, who had been put to work scooping out the ice cream.

"No!" Zoe shook her head. "She's just my dolly, so she should stay over there with all my new toys! And whatever else I might have gotten," she added quickly, trying to hide the fact that she already knew what was in most of the presents. Across the room, Sierra whimpered, wondering if she was going to be stuck there for the rest of the party. Not only would it be uncomfortable, she couldn't move her hand enough to do the movements needed to try to summon her wand to herself. There had been no guarantee that would work, but she wouldn't even be able to try like this!

"You know, she worked hard on this party, too. I think maybe she deserves to enjoy it," Lilly said.

"What did she do?" Zoe asked with a pout, but she obviously knew what her Mommy wanted. "Fine, I guess she's been down there long enough," she sighed, taking her plate back from Robin and starting to head towards Sierra, only to be stopped temporarily by a hug from Lilly.

"Good girl," she said, before sending Zoe on her way with a pat on the bottom.

The rope came off surprisingly easily, making Sierra feel even more silly to have been stuck in it. "Go get some cake," Zoe ordered, picking her own plate up from the gift table where she'd set it down.

For once, Sierra was quite happy to do as she was told. She did have to scurry away after getting her ice cream, and Robin began to reach for her diaper to check it, and probably fill it to justify changing her, but there were so many other girls there waiting for their sweets that the robot couldn't pursue her. Sierra had no doubt that Robin had noticed her fidgeting while she stood there, and that she knew it meant Sierra wouldn't last much longer before she needed a change, but she managed to buy herself a little more time. The cake really was very tasty, but it was hard for Sierra to enjoy it too much when she knew her real treat should be arriving any minute.

Sure enough, halfway through her slice of cake, the doorbell rang one last time. "I'll get it!" Sierra announced, waddling hurriedly towards the front door before anybody could stop her. Despite her hurry, she paused once she got to the door, feeling suddenly anxious at the idea of actually meeting this Dr. Hadalis after speaking to him so many times, wondering if maybe she'd gone too far. Glancing at the still fading red marks on her wrists from the rope helped answer that question as she reached up to open the door.

"Hi," she said shyly, staring up at the tall, bearded man on the other side. The hair on the back of her neck started to stand up as she stared up at him, sure that she felt some slight semblance of power, not unlike how she'd felt when she'd first arrived at Ilvermorny, with all the full blown wizards there. "You're, umm..." she started to say, only to get engrossed in stirring her ice cream on her plate shyly, feeling suddenly very aware of her immature state of dress. That feeling was only amplified as she felt a sudden twinge in her bladder, forcing her to drop her fork and reach between her legs to stop herself from soaking her diaper.

"Dr. Hadalis," he stated, starting to reach out his hand, only to withdraw it. "Don't let me interrupt your... cake," he said with a slight twinkle in his eye. "Are you the birthday girl?"

"Me? Oh, no! No, I'm Sierra." She blushed a little saying it, still squirming in place, letting out a small whimper as a trickle of pee escaped before, finally, the urge to go passed.

"Of course! I should have recognized the voice," he nodded. Sierra's cheeks darkened further. It felt very strange to be seeing him in person, wondering what he thought about all the things she had asked him to do. She still had time to back out of this and tell him she had changed her mind.

"Zoe is in there," Sierra nodded towards the living room, although the sounds of the party had likely already tipped the man off. "She's the one with the pink hair in buns, and..."

"Is she the only one having a birthday?" he asked with a small smile, making Sierra blush again and nod. "I think I'll be able to find her then, but thank you. Now come along."

"Okay," Sierra nodded, obediently walking behind him, his tallness making her feel extra small as they made their way back to the party.

"Good afternoon, ladies!" Dr. Hadalis proclaimed loudly as he strode into the room, Sierra trailing after him. "I hear its somebody's birthday today!"

"That's me!" Zoe announced, rushing up to him. "I'm the Birthday Princess! Who're you?"

"Yes, you are," Dr. Hadalis smiled. "Why don't we come up this way, and I'll tell you." Gently, he put his arm around Zoe's shoulders, leading her through the crowd to the other side of the room.

Sierra was tempted to follow, so she could see what happened next up close, but she knew that this would be her chance. If she stayed there, close to the entrance, while everyone was looking the other way, then maybe she could get her wand back after all. It was all coming together!

"My name is Dr. Hadalis," he announced to everyone. "Your little friend Sierra over there brought me here to give you a very special gift!" He pulled a small, gift-wrapped cylinder from the pocket of his coat, handing it over to Zoe with a bow. "I think you'll enjoy it very much."

Zoe started to tear the wrapping paper off almost immediately before glancing over at Lilly to make sure it was okay. Lilly smiled and nodded, which was all the encouragement it took for Zoe to finish the job, pulling out a rolled up sheet of paper inside.

Sierra had to admit, she was curious as to what this could be. She didn't know for sure, but ever since talking to Dr. Hadalis on the phone, she'd suspected that there was some truth to the rumors that hypnotists like him had some minor access to magic, and meeting him in person had only made her more certain. She'd assumed that his power came from his words, and that he could somehow use them to form spells without any sort of wand, so she wasn't sure what the paper would have to do with anything. She was definitely eager to find out, though! Ever since that incident with Olivia's mother, she had been very interested in the different ways people used to access magic, and this seemed like yet another new one.

Zoe wrinkled her brow as she stared at the paper, then glanced back up at Dr. Hadalis. "What does this mean?" she asked, sounding much less enthusiastic than she had just a few seconds ago.

"Just read it," he urged.

Sierra nodded, nibbling at her cake, engrossed in the show. She needed to wait until everyone was really interested in what was happening anyway, she reasoned, so she could watch for now, too. This was definitely interesting, and different from what she had imagined. Was Zoe reading whatever was on there a part of the spell? It made sense that saying the words yourself rather than just hearing them was bound to be more effective, and even more humiliating to the person once it was over and they realized they had done it themselves.

She pushed her legs together as she watched, feeling her bladder begin to beg for relief again, nearly trembling with excitement. Was this all really going to work? Even a potentially wet diaper wasn't enough to dampen her mood. The air felt electric as Zoe at last opened her mouth and said the words Sierra had chosen as a trigger for the very first thing she'd chosen for Zoe's punishment. "What a clumsy baby!"

In her excitement, Sierra felt her plate slip from her hands, bouncing onto the floor. "Sorry!" she squeaked immediately. "I'll clean it up!" It was unfortunate timing, definitely, but at the same time, it could work in her favor. That gave her an excuse to kneel down, out of sight, and prepare to use her spell. It also blocked her view of the action at the front of the room, which was a pity, especially since Zoe hadn't even dropped the paper yet for some reason, but that was just a sacrifice she'd have to make.

Her first suggestion to Dr. Hadalis had been quite simple. At first, she'd considered just requesting he implant a trigger that would make Zoe weaker in case the bigger girl tried to spank her, but after some thought, she had decided that it would be better to just make her much clumsier, like a toddler. That way, she wouldn't even be able to hold onto the paddle, or any other object of torment, long enough to use them on Sierra. As an added bonus, Zoe would also be unable to hold any cups with just one hand, and even using two, it might be difficult, just like for a toddler. It was useful, and humiliating, and at first, Sierra had thought that would be enough.

But at the end of the first talk on the phone, Dr. Hadalis had asked, "Are you sure that's all?" For some reason, that had made Sierra pause and think. That would solve her basic problem, maybe, but if she had this hypnotist at her disposal, maybe it would be better to do a little more, just in case. So, after a little hemming and hawing as she tried to think of what else to do, he told her to call him back. Afterwards, that had been all she could think about, as she continually tried to think of what else to add to Zoe's hypnosis while she had the chance.

"Very good!" Dr. Hadalis praised Zoe. "Now, on to the next one."

Zoe still sounded very confused, which Sierra took as a good sign. She looked around at the sea of legs in front of her, trying to get a good idea of where Robin was in it, positioning herself for her spell.

"Babies can't walk!" Zoe proclaimed at the front of the room, making Sierra grin.

She wished she could see the girl stumble and fall as she lost control of her legs as well. The idea had come to her a couple days after her initial session with Dr. Hadalis, after trying to resist yet another spanking. Zoe was just so much bigger than her that it was easy for her to wrestle her down onto her lap, or do just about whatever she wanted, really. Sierra doubted Dr. Hadalis could do anything about her height, but he could still bring her down to size by forcing her to crawl, unable to even stand on her own until, as with all the hypnosis, the trigger to return her to normal was spoken.

"Please! I forgot something really important!" she'd had to beg Lilly to let her use the phone again while Zoe was asleep.

"I suppose I'm not allowed to listen this time, either?" Lilly had questioned, but thankfully she'd handed over the phone anyway. "I guess I can't expect a baby like you to remember everything the first time around."

Sierra could just imagine Zoe sitting there, in front of her friends, struggling to be able to stand back up and failing, getting more and more confused. It was sure to be quite the show, and just thinking of it made Sierra giggle a little, but she had to remind herself that she had more pressing business to attend to.

Oddly, when Zoe spoke again, she didn't sound all that panicked when she moved on to the next trigger. "Goo-goo, ga-ga, baby girl," she said, her voice still seeming more confused than scared at what Sierra knew had to be happening to her.

That part seemed to make the whole idea of forcing Zoe to actually say the words that would do this to her worth it. It was almost too cruel, hearing her say it, knowing that those first two phrases were pretty much all she would be able to say until the hypnosis was broken.

That idea had come much quicker, though Sierra had really been trying to find something at that point, searching for some reason to call Dr. Hadalis again. She told herself it was just because it was so unusual for her to have contact with the outside world here, and less that she was really enjoying the idea of finding new ways to humiliate Zoe. This seemed like her best idea yet, ensuring that Zoe wouldn't be able to tattle on her for anything, as she was prone to do. A lot of the time, she even claimed that Sierra had done things that she had been behind herself, or that hadn't even happened at all! It only made sense to protect herself! And, to make it extra fun, Sierra had decided to also make this one force Zoe to drool.

She furrowed her brow as she felt a strange wetness on her own chin, reaching up to try to wipe it off, though she found it unusually difficult to aim her hand correctly. Dr. Hadalis was going to have to read the next part, and it would probably be the most entertaining, so she didn't want to miss it. She'd wasted enough time already anyway, so she moved her hand away from her still damp mouth, and focused, quietly murmuring, "Accio wand!"

Or that's what she thought would happen. Instead, it came out more as, "Gabbia wawa." Her stomach clenched in fear as her confusion slowly faded and she realized what was actually going on. Her eyes widened, heart pounding in her chest as she attempted to get to her feet, only to realize that, sure enough, her legs refused to work. Somehow, maybe just by talking about them with Dr. Hadalis, the triggers were working on her as well! Knowing what was coming next, she turned, starting to crawl out of the room as fast as she could move.

She was nowhere near fast enough. From across the room, she heard, still in Zoe's voice, somehow unaffected by the last bit of hypnosis, "Uh-oh, did somebody have an accident?"

Instantly, all the work she'd done, over the past couple weeks, but especially that day, trying to re-gain her control, was undone. She heard a hissing sound she knew was coming from herself as her padding began to grow warm all around her bottom. Even worse, a series of involuntary grunts began to escape from her drooling mouth as she started to mess her diaper. She froze in place, as helpless as an actual baby to stop what was happening, her diaper drooping even further below the hem of her dress.

That one hadn't even been her best idea! She had just been anxious to hear Dr. Hadalis's voice again, almost as if she was addicted to it, and she had to think of something! Zoe didn't seem to mind using her diaper, but Sierra thought that maybe if she had no control, that would make her feel more helpless. Maybe her seeing that Sierra could do that to her at any time would make her be nicer.

"I think somebody is just trying to get out of her naptime," Lilly had said when Sierra had asked, yet again, to have her cell phone. "Are you even calling anybody, little lady?"

"Yes!" Sierra had pouted. "Just check your call log! I'm sorry, I'm doing my best!" she sniffled, trying to act pitiful. "Planning a party is hard!"

"That's why I tried to tell you," Lilly had shaken her head. "Maybe I'd better just call this doctor and get everything straightened out." Looking back at it now, Sierra wondered if she was remembering correctly, if Lilly really had said 'doctor'. How would she have known that was who she was talking to?

"No!" Sierra's eyes had widened, not wanting Dr. Hadalis to tell Lilly what she was planning. "Just one more time, I promise! I'll get everything fixed!"

Lilly had relented, and Sierra had called, the doctor's voice making her feel much calmer almost instantly. She tried to tell him that this was the last time she'd be able to call, but he still told her at the end that, if she thought of anything else, she could call back.

She'd done her very best not to think of anything more, not wanting Lilly to get suspicious, but there was something empowering, and almost intoxicating, about talking with Dr. Hadalis, and when she came up with the final trigger, she just couldn't resist begging for the phone one last time. It had seemed like such a good idea at the time. One last command, to make Zoe do whatever Sierra told her, just in case everything else wasn't enough to show Zoe that Sierra was now the one in charge. Sierra had promised she would only use it if she really needed to, but just knowing she could do it might have been too much to resist.

Hearing the words come from Zoe's still completely coherent mouth instead was horrifying. As she heard, "Such a good baby girl!", there was something inside her mind that she could almost feel change as her ability to resist Zoe's orders faded away.

"Come to me!" Zoe proclaimed, and sure enough, Sierra had no choice but to obey. No matter how hard she tried to stop herself, her arms and legs kept moving, crawling through the crowd up to the front of the room, where Zoe was waiting.

Zoe, who was still standing, still holding the paper, clearly still able to talk, and, Sierra could tell from her even lower than normal vantage point, still in a clean, dry diaper. The hypnosis hadn't affected her at all! And yet, there Sierra was, essentially an overgrown baby now, completely in Zoe's control, all because of her own plans! All because of...

Her eyes flashed as she glared up at Dr. Hadalis, finally realizing that he had betrayed her. "Goobah tuwie bawah!" she growled at him, her inability to form a single coherent word making her all the more upset. His eyes twinkled as he stared down at her.

"Sierra planned all of this on her own for you! I think she just wanted to be a better baby doll for you! Isn't that sweet of her?" Lilly said, stepping over towards Zoe. "Isn't that just the sweetest present?"

Lilly and Dr. Hadalis exchanged a look, confirming in Sierra's mind that they were in cahoots. She wasn't sure how that could be at first, but, of course, she had been using Lilly's phone all along. All she would have to do is redial the number Sierra had used and see what she had been planning for the party. If she'd done that, it was no surprise she would turn the tables on Sierra! She'd probably even encouraged Dr. Hadalis to keep asking her for more ideas, to let her dig herself into a deeper and deeper hole, and Dr. Hadalis had probably used his mind control magic to keep her wanting to do just that! She'd never stood a chance! Unable to do anything else, Sierra started to cry.

"Thank you so much!" Zoe exclaimed, bending down to give Sierra a hug. "That's such a great present!" She gave Sierra's diaper a pat, then grinned. "Aww, poor baby Sierra! Look at how full your diaper is!" she teased. "No wonder you're so upset! Here you go, suck on this! It'll make you feel better!" A large pacifier was shoved into Sierra's mouth, and she had no choice but to start sucking on it.

"I can take care of this!" Robin declared, stepping forward, bearing her bag of Pampers. "Come on, Sierra, I'll take you to the nursery and get you all fixed up!"

"No," Zoe stepped in, though Sierra knew not to be glad for that interruption from the look in the girl's eyes. "We can change her here! Sierra, why don't you get your changing pad and supplies for Ms. Robin and bring them here?"

"Hold on, baby Sierra," Dr. Hadalis stepped in as well, forcing Sierra to stop mid-crawl. "She won't be able to carry them like this, Zoe. Here, just say these," he said, pointing to a line on the paper Zoe was still holding. Zoe pouted, clearly not wanting to release any of her power on Sierra, until Dr. Hadalis encouraged her, "You can always use these on her again when she gets back."

"Okay!" Zoe was satisfied with that answer, turning to Sierra. "Look how coordinated the baby is! And look at baby's first steps!"

Cautiously, Sierra tried once again to get back to her feet, this time succeeding easily, as if her failure to do so just moments earlier had never happened. "Now go on! We're waiting!" Zoe waved her off, and Sierra turned and hurried off towards the nursery, her diaper squelching between her legs in her rush, unable to think of anything else but doing what she was told, gathering up the changing mat, baby wipes and powder, and carrying them all back to the living room, where Robin seemed to be doing her best not to look annoyed that her obvious plan to get Sierra alone had failed. Sierra dropped the supplies at the robot's feet, then turned to Zoe eagerly, looking for some praise for doing what she was told.

Instead, Zoe quickly said, "Such a clumsy baby! Babies can't walk!" and Sierra instantly started to wobble before falling onto her thickly padded backside, making the mess inside all the worse from the impact while beside her, Robin began to spread out the changing pad. "Lay down like a good girl and let Robin change you!"

Sierra whimpered behind her pacifier as she helplessly did the last thing she wanted, laying down in front of everyone, letting Robin bend over her. She was sure she could feel her wand now, so close but at the moment it might as well be a million miles away. Even if she wasn't being watched, she couldn't speak to say the incantation, and couldn't use her hands well enough to even try to slip them into Robin's pocket and pull it out, if that would even work.

Robin pushed Sierra's dress up, fully exposing her swollen diaper and untaping it. "Whew! Somebody made a big mess!" Robin teased as she started to wipe Sierra clean, the girl's cheeks bright red, sure that everyone was staring at her. "That's all right, sweetie, we'll get you into a nice, new diaper in no time!"

Sierra gulped as Robin wrapped the diaper up in itself, then pulled out one of the fresh Pampers, lifting her legs and sliding it underneath before grabbing the powder and starting to sprinkle it onto Sierra's crotch. Sierra tried to force herself to roll off the diaper, not knowing what it might do to her, but she had been told to let Robin change her, and she just couldn't make herself disobey.

To her surprise, Robin stopped massaging the powder into her skin, and all of the sudden she heard people start to giggle around her, and even a few, "Aww!"s. Confused, she tried wiggling free of the changing pad again, only then realizing that the diaper beneath her was feeling a little wet, and when she started to sit up in shock, she saw that she was, indeed, starting to dribble right in the middle of her change, just like a little baby.

"It's all right," Robin cooed, pushing Sierra back down flat. "Its just a little! Your Pampers can handle it!" And with that, she brought the front of the diaper up between Sierra's legs, forcing her thighs apart slightly, and taped it into place.

As soon as the last tape was secured, Sierra knew something was wrong. Some part of her mind felt more fuzzy, and she just felt weaker in general, but it was only when Robin bent forward to kiss her on the forehead that she realized what was wrong. Even with the robot that close to her, she no longer felt the presence of her wand. She couldn't feel any of the magic energies that she normally sensed all around her, even if she couldn't access them.

"We made these just for you," Robin whispered, her voice precisely tuned so that only Sierra could hear. "We analyzed your little toy and made something that would be sure to keep you out of trouble until I can collect you and take you back home, and make sure you can't escape again once I do."

Sierra gasped, pawing clumsily at the front of her diaper for a moment or two before realizing she was still in front of everyone. Robin just smiled, gently scooting her off the mat and starting to fold it up.

"You should thank Robin!" Zoe 'suggested', then giggling with everyone else at the garbled mess of syllables that managed to escape from behind Sierra's pacifier. "Now go throw away your dirty diaper and put your changing things away!" she said, allowing Sierra to walk and hold things again before she went trotting off through the crowd, blushing bright red as she passed everyone with her stinky cargo.

Once she was in the nursery, she immediately threw away the diaper and put all the supplies up before she was freed from Zoe's order and able to do what she wanted. Immediately, she looked down at herself, trying again to undo the tapes. She could grab them now, but when she tried to tug them off, they refused to budge an inch, no matter how hard she pulled. She whimpered, stomping her foot angrily, the full weight of what had just happened starting to hit her.

She had planned to end today with full control over Zoe, and hopefully the return of her wand. Instead, she was even more helpless than ever, any hope of regaining any bit of her maturity riding solely on Zoe's whims, totally cut off from her powers, and maybe trapped in this diaper until Robin decided otherwise.

"Aww, is it too loose?"

Sierra spun around at the sound of Zoe's voice, blushing as she realized the girl had managed to end up right behind her without her noticing. Zoe reached out and easily undid the tape Sierra had been fighting with for what felt like at least five minutes, tugging the diaper tighter around Sierra's bottom and smoothing it back into place, making Sierra suspect that Robin's personalization of these diapers had included making it so that only Sierra herself couldn't remove them.

"I thought you were looking a little fussy, so I told Mommy I'd put you down for a nap. I know parties can be stressful for little babies like you," Zoe said, lowering the rails of the crib and herding Sierra inside, tucking her in nice and tight. "Maybe there'll still be some cake left when you wake up. I bet Laura would love to feed it to you!" She bent down giving Sierra a kiss on the forehead, then raising the bars again. "Thanks again for the present! Its just what I wanted!"

Sierra whimpered as Zoe walked away, trying to make some kind of noise that Zoe might realize meant she wanted Zoe to use the trigger to undo everything, since there was no way she could get out of the crib anyway. Sierra knew what that phrase was, of course, but even if she could have spoken it at the moment, she had made sure Dr. Hadalis made it so that the subject, which she now knew had been herself all along, couldn't use it on herself.

To her surprise, Zoe stopped at the door and turned. "Oh, I almost forgot!" she said. "What a perfect baby!"

Sierra sighed as the strength and coordination flowed back out of her hands and legs. That phrase was meant to activate all of the triggers at once, or, as in this case, any that weren't already active.

"Night-night! I'll make sure nobody bothers you!" Zoe smiled, switching off the lights and stepping out of the room, closing the door behind her.

Sierra groaned, pushing weakly at the blankets, but she couldn't even make them budge now, not that it would do any good. The bars of the crib were too high for her to climb normally, and now that she could only crawl, it was definitely out of the question.

Part of her mind told her she deserved this for trying to put Zoe in this same position. She had to remind it that she had made sure to include a trigger phrase, 'Such a big girl', that would instantly undo all of the other effects, at least until she used one of them again. She was sure Dr. Hadalis had included that on his paper as well, but she wondered if she would ever actually hear it, or if Zoe would make sure to always keep at least one of the triggers active in Sierra's mind.

The only comfort she got as she squirmed in her crib, feeling her diaper grow slowly wetter around her with no way of stopping it, was that Zoe really did seem pleased. Now, she could make Sierra the perfect doll, having her do whatever she wanted, whenever she wanted. That in itself wasn't much of a consolation, but it did mean that Zoe might be a little more protective of her. Like any little girl with her favorite toy, hopefully she would want to keep Sierra at her side at all times, which would at least keep Robin from being able to easily take her back to the diaper dimension.

That was her only hope now. Robin had been there, and had no doubt recorded all of the trigger phrases for herself, which combined with the diapers meant that Sierra didn't stand a chance against Robin on her own. She was just going to be the best dolly she could for Zoe to make sure she never got bored with her... Not that she really had a choice anymore.
