"Come on, this isn't fair!" Sierra pouted as she trailed after Lilly, going as fast as she could to try to keep up with the taller woman's pace.

"What isn't fair? I have to go out for the day, so I have to hire a babysitter. That's just how it works!" Lilly said, grabbing her purse and looking through it to make sure she had everything she needed.

"That's just it! I'm the babysitter!" Sierra whined, stomping her foot.

Lilly just turned, eyeing Sierra up and down. Sierra blushed and squirmed under her gaze, glancing down at herself, too, seeing herself standing there in her yellow t-shirt with the duck on it, barely going down to her belly button, and the Pamper beneath it, expanded with her own spell to fit her perfectly, despite originally having been the same size as the one taped on the stuffed bunny she was holding. Along with the two ponytails in her hair, held with ribbons that matched her shirt, Sierra knew she certainly didn't look the part of the babysitter.

"Well, I was supposed to be!" Sierra glanced down at her feet for a second before looking back up at Lilly. "I don't need a babysitter!"

"Of course you don't!" Lilly agreed, to Sierra's surprise. "Zoe is here to take care of you! But she's still getting used to taking care of her little dolly, so she needs help! Besides, somebody has to take care of her, too!"

"I am not a doll!" Sierra huffed, stomping her foot again.

"I can't believe you're being so fussy after what happened last time," Lilly said casually as she closed her purse back up, satisfied that it was packed correctly. "Do I need to give you a nice, big, soapy enema before I leave so you'll behave for the babysitter?"

Sierra gulped, taking a toddling step back from Lilly as she realized she might have pushed her too far. "N-No..." she said nervously, afraid the question was rhetorical.

Luckily, the doorbell rang just then, halting Lilly as she advanced on the petite girl in front of her. "Well, that should be Robin," she said with a smile, grabbing Sierra's free hand. "Come on, you'd better come meet her! But don't think I've forgotten about this!" Lilly swatted the rear of Sierra's thick diaper. "If Robin tells me you were fussy today when I get back, we'll take care of it then, before I put you to bed extra early!"

"B-But..." Sierra pouted as she was pulled through the house, toddling behind the taller woman, feeling very much like a little kid, especially once they came to a stop in the living room.

Zoe was there, where she had been when Sierra had followed Lilly to her bedroom after hearing about the babysitter, still in her blue shortalls with nothing except her diapers underneath, and its three rows of lace across the backside. With her, however, was somebody Sierra had never seen before, obviously the babysitter.

Sierra wasn't quite sure what she was expecting. Maybe some old woman who smelled like mothballs, or someone a bit older than her with a riding crop, dressed in black leather. What she actually saw there was quite different, however. She looked like she was about Sierra's age, perhaps a little younger, considering the cheerleading uniform she was wearing that made Sierra think she could still be in high school, though definitely as a senior if that was the case. Sierra gulped as she stared up at the tall girl, feeling even more small than usual, especially as she was unable to help glancing down at her ducky shirt after being unable to help noting just how well this Robin girl filled out her uniform.

"And who is this?" Robin cooed, patting Zoe on the head as moved over to Sierra, bending down right in her face with a smile, making the smaller girl squirm and blush, especially when she felt the girl's hand reach out to pat the padding between her legs. "She's a little wet, whoever she is!" she announced quite loudly.

"This is our little Sierra," Lilly said. "She's Zoe's little baby-doll, though I'm sure she won't mind having your help looking after her!" Sierra's blush darkened as Lilly reached down and patted her diaper as well. "She'll be all right for now! We're running a little low on her diapers and I haven't had a chance to get more, so she can wait a little longer for a change. Her Pampers can handle it!"

Sierra pouted at that. There was no way Lilly could know about her diapers, and no way for Sierra to tell her without revealing she was a witch, but those diapers would hold up for much longer than Lilly thought. Sierra's first attempt at expanding Pampers had been a bit of a disaster, absorbency-wise, so these ones added some bulk to try to help with that. They also had an anti-leak charm, just in case. They were designed to make the tip of her wand - which was still lost in the bottom of Zoe's toy chest as far as she knew - glow slightly when they had been used, so she would know her charge needed a change, because otherwise, they never felt overly well-used... At least from the outside.

Sierra hadn't realized it when she'd made the charms, but from the inside, it was always quite evident just how wet, or messy, those diapers were, and she'd been dealing with diaper rashes off and on ever since she'd begun her new life here as Zoe's doll, much to her embarrassment. Especially when Lilly decided to mention it to other people, so that was just what the woman did. "Make sure you use lots of diaper rash cream on her when you do change, her, though! She was looking a little red this morning!"

"Poor thing! We can take care of that!" Robin said, patting Sierra's diaper again. Unfortunately, this time was far worse. Sierra thought she felt something poke into her diaper, but she just assumed Robin was slipping a finger inside. A moment later, however, her eyes widened and she let out a gasp as she felt a huge, warm, mushy mass begin to fill the seat of her diaper. This couldn't be happening! Not right in front of everyone, especially her new babysitter, whose hand was still on her expanding diaper. Sierra stared down at her feet, blushing, knowing there was no way Robin could fail to notice what was happening.

Unfortunately, neither could anyone else. "Mommy, Sierra's pooping her pants again!" Zoe giggled.

"Am not!" Sierra sniffed, squirming in her increasingly full diaper. It really didn't feel like she was doing anything at all, and her tummy still felt just as full as before, but obviously something was going on! It finally stopped, just in time for Robin to remove her hand and Lilly to move hers there in its place.

"Oh, you most certainly did, young lady!" Lilly shook her head, giving the lumpy Pamper a swat. "Did you do this just so Robin would have to change you right away after all? Well, that's just too bad! You'll still be all right for a little while, and if you get a rash, you only have yourself to blame. Your behavior for today is not off to a good start." Sierra bit her bottom lip, shuffling her feet nervously as she remembered Lilly's threat from earlier. "She can be a bit of a handful," Lilly smiled apologetically at Robin.

"Don't worry, I'm sure I can handle the two of them!" Robin assured Lilly. And with that, Lilly kissed Zoe and Sierra on the foreheads and went on her way, leaving Sierra standing there in her full diaper in front of her new teenage babysitter. Sierra wished she could fall through the floor right then. The whole thing was quite embarrassing, not to mention confusing. Had she actually pooped herself without noticing, or being able to stop it?!

"Why don't you two play in your nursery for a while?" Robin suggested, picking Sierra up and resting her on her hip, then holding her hand out for Lilly. While the girl had probably nine inches on her not quite five foot frame, Sierra was still quite surprised by just how easily she had been able to lift her, and she carted her to the nursery with what seemed like very little effort.

"I don't want to play with her!" Zoe complained on the way as she trotted alongside Robin. "She's stinky!"

"She smells just fine!" Robin chuckled, and as Sierra took a tentative sniff of the air around herself, she realized the girl was right. It didn't smell like she'd had an accident at all! But with Robin's hand planted firmly under her bottom, she could feel it even more than ever!

"She will!" Zoe insisted, hurrying over to her coloring books and crayons once they were in the nursery and grabbing them all, taking them to a corner of the room and starting to sort through them.

"Go on, you play, too!" Robin said, setting Sierra down with a pat to her diaper, then walking back out of the room. She started to toddle over towards Zoe, but the other girl just glared at her, gathering her stuff into a tighter pile in a way that clearly demonstrated she didn't want to share.

Sierra couldn't help but feel a little offended at first, until she realized this was too good an opportunity to pass up. Normally, Zoe didn't let her choose what they played with, since she was the one in charge, but if she was set on coloring by herself, then Sierra could finally go through the toy box and get her wand back! Clearly, she needed it, because it seemed like this place was really starting to get to her for her to just have an accident like that!

The lid to the toy box was just as heavy as she remembered, if not more so. Sierra groaned, straining as she pushed it upwards, wishing she hadn't relied so much on magic while she was at school. They'd warned her about that, but, being from a non-wizard family, the temptation had just been too great, and now that she didn't have her wand it was more difficult than it probably should have been for her to do physical stuff like this.

She let out a small sigh as she stared down into the box at all the toys piled in there. There were a ton of them, though there was still room for quite a few more, and at first glance, her wand wasn't among them at all. Of course, it was rather small and thin, so it had likely fallen down near the bottom, and since it was enchanted to look like the most boring toy possible to anyone other than Sierra, that made sense. Zoe had probably pushed it aside many times while getting playthings, and piled stuff on top of it.

It was a very big box, and Sierra had to stretch a little to even brush aside the top layer of toys. To dig deeper, she had to get up onto her tiptoes, then nearly climb up the front of the box, her lacy ankle sock clad feet slipping against the heavy wooden surface as the lip of it pushed into her tummy. It wasn't the most comfortable, or efficient, way of searching, so it wasn't much of a surprise that she didn't seem to be getting anywhere. This had to work, though, so she just leaned in further, putting all her concentration into just finding the wand that would help her get out of here.

She didn't even hear Zoe walk up behind her. She didn't know the other girl was there until she felt her hands press against her mushy backside, pushing her higher up. For a second, Sierra thought she was trying to help, and it was helping her get closer to the bottom of the chest. Then she realized Zoe wasn't stopping. She started to kick her feet, trying to find some grip on the box so she could stop what she knew was about to happen, but that only made Zoe speed up, shoving Sierra up and into the toy box, which her petite frame fit into just right.

"I told you to stay out of my toys!" Zoe exclaimed angrily. "Well, if you want in there so bad, you can just stay there! You're just a dolly anyway!"

Sierra sputtered and twisted, contorting herself to try to get free from the mass of stuffed animals and oversized baby toys she'd been forced into face first, managing to turn over just in time to see Zoe start to shut the lid. She gasped, letting out a burst of warm pee into diaper in fear as she reached upwards, trying to hold the top open, but she had sunk too far into the collection of toys to reach, and it was slammed shut with a loud thud, sealing her into the darkness.

"No!" she wailed, trying to bang her fists against the side of the box, only to be met with a loud squeak as she mashed a toy instead, the unexpected noise causing her to start to wet again. This time, however, surrounded by darkness with no apparent way out, she couldn't make it stop, even as she clamped her hands to her crinkly crotch, feeling herself helplessly flood the already full garment. Sierra was not a fan of the dark at all. If she hadn't had to share a room at school for so long, she would probably still sleep with a night-light, and even now she really didn't mind the fact that Lilly kept one on in Zoe's nursery at all times.

"Let me out!" she yelled, unsure whether Zoe could even hear her outside of the chest, not that she was likely to care. "Zoe, please, I'm sorry!" she whimpered, still flailing futilely among the toys as she sniffled, the last of her bladder's contents dripping its way into her now very well-used diaper. She knew she should probably be grateful for the spell she'd used to keep it from leaking, since it would probably be doing that just now, and Zoe would be mad at her if she knew that, but at the moment she didn't really care if she ruined a few of the other girl's toys.

It felt like hours, but according to the big sun shaped clock on the wall of the nursery it was only a minute or two later that light suddenly flooded her prison, making her shut her eyes to avoid getting blinded. Before she could even open them again, she felt herself being picked up, and knew right away that it was Robin's strong arms around her, as she heard toys spilling out onto the floor as she was dragged out and set back on the cheerleader's hip.

"That was not funny, young lady!" Robin lectured sternly, encouraging Sierra to open her eyes a little quicker to see Zoe's pout.

The girl didn't even apologize, she just whined, "How did you know?"

"Babysitters hear everything," Robin said simply before turning to Sierra, readjusting her position a little. "Hmm, you seem a little wetter," she observed. "But I need to deal with this first." Sierra felt that same odd feeling in her diaper as before, like something pushing its way in from the leg hole, and then, without warning, she felt the same warm, thick mush begin flowing into it.

"No!" she gasped quietly, biting her bottom lip as she fidgeted, frantically trying to stop it, but she still couldn't feel it at all, much less stop it. She had just gone, though! How could she need to go so badly again this soon, and this much? It felt like just as much as the last time, if not more, though it was hard to tell, having not been changed since then.

Robin frowned and looked down at her as it finally ended, making her blush and stare down at the floor. "There seems to be something wrong," Robin mused, almost to herself, just before a third wave started. Sierra gave a humiliated squeak that Robin didn't acknowledge as she moved the girl off of her hip, setting her down not on the floor, but in an oversized baby bouncer.

"No, not there!" Sierra blushed as her loaded diaper was set into the seat, earning herself a pat on the head by Robin.

"That should do for now," Robin said before the girl turned away, her eyes locking on Zoe.

As she walked away, Sierra's diaper finally stopped filling. In her relief, she looked down at herself, surprised at how relatively clean her diaper looked from the outside. From the corner of her eye, she thought she saw something moving across the floor towards Robin, but before she could look up, or even say anything, it was gone. Sierra sighed, pouting as she did her best not to move, but the messy diaper around her waist made it difficult to feel comfortable, prompting her to squirm, which, unfortunately, only made her seat start to bounce and jostle her even more, making her feel all the more uncomfortable.

"Well, then," Robin said, standing over Zoe with her hands on her hips. "Do you have anything to say for yourself?"

Sierra glanced up, wondering what was about to happen. Zoe shrugged, putting on her best innocent face, the one that always seemed to work wonders on Lilly. "I was putting away my toys like a good girl!" she smiled, batting her eyes.

"That's what I thought," Robin shook her head, sticking her hand into her pocket and coming back out with a pink, heart shaped paddle with holes drilled into it. Zoe's eyes widened, and even Sierra couldn't help but gasp at the sight. At least since Sierra had been around, Lilly had always allowed herself to get talked out of spanking Zoe when she was naughty. Robin, on the other hand, didn't look like that was going to work on her.

"I-I'm sorry!" Zoe changed her tune immediately, starting to toddle over towards Sierra to apologize, only for Robin to reach out and grab her by the wrist, pulling her over to the rocking chair and yanking the girl over her lap. There was a loud thwap and crinkle as the paddle came down on Zoe's backside, the girl jumping and yelping.

Despite her own situation, Sierra couldn't help but giggle at the sight. After everything Zoe had done to her, it was rather satisfying to see her get spanked, especially watching her struggle in vain to escape the babysitter's grip, tears quickly welling up in her eyes.

After ten swats, Robin lifted Zoe off her tummy, setting her upright on her lap for a quick hug before putting her down on the floor. Robin stood, patting the still sniffling Zoe on the head as she walked over to Sierra, plucking her out of the bouncer and carrying her over to the changing table. "Zoe, while I take care of Sierra, I want you to clean up those toys."

"But she's the one that dropped them all!" Zoe whined, but a glare from Robin silenced her quickly as she shuffled over to her toybox.

"Your Mommy tells me you're supposed to be sorting through your toys to give some of your old ones you don't play with anymore away. I think this would be a good time to do that, don't you?" Zoe nodded obediently, but from her expression it was clear she didn't agree at all.

Sierra wrinkled her nose as her mushy bottom was lowered onto the crinkling surface, though she was quite grateful to feel Robin finally untape the diaper, freeing her from the squishy prison, and begin to clean her up.

"My, that's fuller than I thought," Robin observed, making Sierra blush. The girl seemed quite good at her job, however, and made short work of making sure Sierra's bottom was clean and taping her into a fresh magic Pamper. Instead of putting her back on the floor afterwards, however, she picked her back up, carrying her over to the rocking chair, where the paddle was still waiting. It looked even bigger up close, and quite threatening. For a moment, she found herself wondering how that had fit into Robin's pocket.

"Wh-what are you doing?" Sierra gulped, wriggling worriedly as Robin picked up the paddle, then sat down, turning Sierra over onto her stomach across her lap, giving the girl an excellent view of Zoe, squatting in front of her toy box and tossing stuff back inside.

"It isn't nice to laugh at your poor sister while she's in pain," she pronounced.

"That's not fair!" Sierra squeaked. "She..."

"I know what she did," Robin said. "And arguing isn't helping your case, young lady." With that, the punishment began, the paddle slapping against Sierra's bottom hard enough to bring tears to her eyes, even through her thick diaper. Her vision blurred, but not enough to keep her from seeing Zoe pick up her wand, examining it with distaste, almost immediately dropping it off to the side, the beginning of her pile of unwanted toys, joined mostly just by old stuffed animals that were nearly falling apart.

"S-Stop!" Sierra whined, thrashing in the babysitter's grasp, trying to break free to go grab her wand so she could get out of this place. "Let me go!"

"I told you to stop arguing," Robin reminded her, punctuating it with another whap. Sierra could practically feel her bottom growing red already, just after two! "One more word out of you and you'll get just as many spanks as Zoe."

Sierra wanted very much to point out that Zoe's spankings were much more well deserved, so she ought to have had more, but she forced herself to bite her tongue, twisting and whimpering her way through three more swings of the paddle, before Robin gave her a hug, then put her down on the floor.

"That was your punishment for laughing," Robin told her. "Now I'm going to punish you for sassing me about it."

"B-But..." Sierra pouted, still sniffling from the spanking.

"No buts, young lady, except yours in the corner," Robin shook her head, picking her up off the table and setting her down on the floor, patting her throbbing backside through her diaper. Sierra turned to stare up at her in disbelief for a moment, but it was obvious the girl wasn't joking. She stuck out her bottom lip, hands curling into fists, but with her bottom still freshly reddened, she didn't dare say anything. Sulking, she stalked over to the corner, feeling ridiculous to be standing there like some naughty toddler. "Don't think I didn't see that look," Robin told her. "Because of that, I'm extending your time-out to half an hour."

"What?!" Sierra spun around before she could stop herself, and in a flash Robin was right beside her, spinning her back around and smacking her diaper.

"That's an hour, then," Robin informed her. "Are these the toys you're getting rid of? Good work! Let me get these out of your way. Look after Sierra for me."

Sierra twitched nervously as she heard those words, wanting to go grab the wand. She was too afraid to move from the spot now, though, especially since she doubted she'd have been able to get the wand away from the bigger and stronger Robin. All she could do was grumble, "No fair" and stomp her foot defiantly... But only once she had heard Robin leave the room. She had a feeling Zoe wasn't going to let her get away with cheating, either, so she was going to have to ride out the whole hour.

Or so she thought. A minute or two after she'd heard Robin's footsteps retreat from the nursery, she heard the door begin to close. She wasn't able to resist the urge to turn her head to see what was happening, only to find Zoe standing behind her, Robin's paddle in hand, evil smile on her face.

"That really wasn't very nice of you," she said, tapping the paddle against her open palm. "I think Robin let you off way too easily!"

Sierra gulped, squirming in place. She knew that, on the other side of the house, her wand was free from the toy box, and probably quite easily accessible, if she could just get to it. Unfortunately, Zoe was standing between her and the door, and there was no way around her.

"Come on, it's time for your real spanking!" Zoe declared, reaching out and grabbing Sierra's hand. Sierra tried to dig her heels in, to prevent the larger girl from dragging her across the floor, but Zoe was stronger than her.

"I-I can't!" she protested. "R-Robin told me to stay here! I'll get in trouble!"

"Oh, don't worry! I won't tell! Probably..." Zoe grinned as she sat down on the rocking chair, dragging Sierra over her lap. As she was pulled down close to Zoe's diaper, she caught a whiff of an all too familiar smell, a blush tingeing her cheeks as she realized she was about to get spanked by somebody in a messy diaper. "Now, let's get this off..."

Sierra gasped as she felt Zoe's fingers on the waistband of her diaper, realizing what the girl meant. She was going to give Sierra a bare bottomed spanking! "N-No, don't!" she squealed, trying to wriggle away. "I-I'm supposed to wear my diaper, you know that! I'll get in trouble!"

"Hmm, that's funny," Zoe smirked. "All this time, you've been complaining about not needing these diapers, no matter how many times you use them. And here you are, practically begging me not to take them away! Just wait until I tell Mommy how much you really do love your Pampers!"

Sierra blushed, reaching back to try to grab her diaper and hold it in place, but Zoe had already slid it down around her knees. "Don't be nervous!" Zoe told her, patting her wiggling bottom. "I've practiced this plenty of times! I'm sure I can handle it for real!"

Sierra knew that was true. When Zoe thought Sierra was acting up, Lilly would let her do just this, yanking her over her lap, sometimes even taking down her diaper, but she always made sure Zoe just gave her a few light taps, even though Sierra could tell she often wanted to do much more. She gulped as she felt Zoe's hand slide across her backside.

"She did all right for a start, I guess," Zoe mused. "But I want to see this little bottom bright pink!" And, with no more warning than that, she started the spanking. It was hard to judge for sure, but it didn't seem like Zoe was hitting her as hard as Robin had been, but without the diaper in the way, she didn't have to. And she was definitely spanking her hard enough!

Sierra squeaked and squealed, making no effort to keep quiet, hoping that Robin would hear her and come to her rescue, but with the door closed, she had no idea if it would happen or not, and after the first few minutes, she gave up hope, staring to bawl and kick her legs while Zoe continued to warm her backside. It seemed like she'd made it her mission to make sure the paddle found every inch of Sierra's bottom, and before long, the whole thing felt sore and hot. Sitting was not going to be fun after this!

Finally, Zoe seemed to have had enough, dropping the paddle to the floor and moving her hands to Sierra's rump, giving it a pat and then rubbing it. "You're practically glowing," she giggled after a moment. "I think it suits you! I guess it'll do for now, but maybe I'd better hang on to this paddle so we can make sure it stays this way!"

Sierra whimpered, still crying as Zoe pulled the diaper back up into place, the thick padding only making her bottom feel warmer underneath it. "Now get back to the corner, or I'll tell Robin you were out!"

Sierra toddled back into place obediently, trying to rub her now twice spanked rear through the diaper as she stared at the wall for what felt like days. There was nothing to do but think about how she'd just been spanked, diapered, and put into the corner, which made it all but impossible for her to put an end to her post-spanking crying. It was all so unfair! She was an adult, she shouldn't have to deal with any of this! She wasn't sure it was really any worse than anything else she'd been through, especially when she'd opened the door to that weird alternate dimension for a school assignment, but at the moment anyway, it definitely felt that way!

Finally, she heard Robin come back into the room. "Uh-oh, somebody's stinky!" she announced right away, getting a giggle from Zoe. She could hear the soft crinkle of Zoe being lowered onto the changing table, and did her best to stop the last of her tears before Robin could finish and come see her. It didn't seem to matter much, though, because the babysitter asked, "Zoe, is your sister crying?"

Briefly, Sierra thought that maybe this was a good thing, and she could get Zoe in trouble for what she'd done, but Zoe pre-empted her by lying, "Yeah! She tried to get out of the corner and I told her no! She got so upset she started throwing a tantrum and crying! She's such a baby!"

"It looks like it," Robin agreed. "You're a good girl for taking care of her for me. I think it's about time for your nap, though, isn't it?"

"I guess," Zoe sighed.

By the time Robin got back to Sierra, Zoe was already tucked into her crib, sucking on a bottle of milk as her eyelids started to droop. "She was lying! She..." Sierra grumbled as soon as Robin turned her around and she knew it was safe to talk.

"Be quiet, your sister is trying to sleep," Robin lectured, cutting her off. "I'm sure you're still mad at her for what she did, but I won't have you waking her up just to make up some story to get her in trouble." Robin picked Sierra up, but rather than taking her to the crib, she carried her to the door, where she paused to turn out the lights. "Sleep tight, Zoe!" she said softly, starting to walk towards the door.

"Where are you taking me?" Sierra gulped nervously.

Robin chuckled. "Don't look so scared, little one! I'm not going to eat you! I just think it would be best to separate the two of you, at least for naptime, to give you both a chance to calm down a little more." She turned out the light and walked out the door, closing it behind her as she carted Sierra off to the living room. Sierra's eyes widened as she saw the pile of toys Zoe had discarded sitting in the middle of the room, but Robin didn't even give her a chance to look for her wand among them, instead plopping her down into a huge pink and purple infant car seat, fastening the harness tightly into place around Sierra.

Lilly and Zoe obviously had a lot of oversized baby furniture, but nothing like this! Sierra had a feeling she could fit into a booster seat if she had to, but this was clearly a car seat intended for little babies, complete with a carrying handle. There was no way she could fit one of those! She'd never seen one of these this size! At least, not in this dimension. What was going on?!

Robin took a step back, her eyes briefly turning red as a light began to shine from them, scanning the captured Sierra up and down. "Just as I thought," she said. "You are the one I was looking for. Now, I think it's time to take you home."

Sierra gulped, squirming against the tight straps holding her against the seat. She'd seen that red light before, though not coming from some cheerleader. "Wh-what do you mean?" she asked, eyes darting over towards the toys again. Her wand was right there! If she just had it, maybe she'd have a chance!

"The Cases miss you," Robin informed her, making her blood run cold as her fears were confirmed. She had lived with the Cases while she was in that strange dimension! There was no way she was going to let this girl take her back there! She struggled, trying to find some slack in the straps, but they refused to budge. She looked back over at the toys, wishing she had studied harder when it had come to wandless spells. They were useful for just this kind of situation, but she was terrible at them! And, as Robin grabbed the handle of her carseat and began to pick her up, she knew she was running out of time.

"Wh-who are you?" she asked quickly. "Some inter-dimensional bounty hunter?"

Robin chuckled. "In a way, I suppose. My main purpose is to look after babies, but I was designed specifically to go after runaways like you. The old model was simply too conspicuous in these less-evolved dimensions."

Sierra's mind froze in the middle of trying to work up the strength to summon her wand as she finally realized exactly who - or, rather, what - this was, the revelation making her bladder release into her diaper. She fidgeted, cheeks starting to glow red as she thought back to her time in the robotic nursery, and the huge robot caretakers she'd seen there. Just like Robin with the paddle, they'd always seemed to have access to whatever they needed in the pockets of their aprons, even if the item was realistically too large to come out of there.

"My, my, wet again," Robin shook her head. Sierra watched in horror as a silver tentacle popped out of the girl's back, darting towards her and sliding its way into the leghole of her diaper, feeling just like that odd sensation of intrusion she'd felt back before she'd 'messed' her diaper those times earlier. And, sure enough, she felt her diaper begin to fill with the same goop as before. It was comforting to know that she hadn't had an accident those times earlier, but that didn't do much to help her now as her diaper began to expand, pushing against the strap on her crotch, though not nearly as much as it should have for as much as she could feel being pumped into it.

Robin seemed confused by that, shaking her head. "I must need to refill my rash prevention solution reserves," she said, letting another long burst of the mush out before the tentacle slid back into place on her back, blending in perfectly with the skin there. Sierra let out a small gasp as she realized that had been what she'd seen out of the corner of her eye right before Zoe's spanking. If only she'd been paying more attention! "Don't worry, little one, that should last you until we get home. They have plenty of diapers for you there, so you shouldn't need it as much anyway!"

Sierra supposed she could see the logic in Robin's reasoning after what Lilly had instructed her to do. If this really was one of those Robo-Nannies, she was programmed to take care of 'children' like her, so when ordered to give Sierra limited changes, it made sense that she would try to prevent her from getting a rash. It also meant something else, though! Something much more important to the matter at hand!

"Are you really going to leave Zoe here all by herself?" she asked pointedly.

"Zoe has a Mommy to take care of her," Robin responded. "And there is no evidence that she has ever even been to our world. She belongs here, unlike you."

Sierra sulked, wanting to point out that she didn't belong in that crazy place, either, but instead she said, "Yeah, but she's still a baby, isn't she? As a nanny, are you really just going to take me off and leave her here alone until her Mommy comes home?"

Robin's expression froze for a moment. It was just long enough for Sierra to wonder if that would work, and then, thankfully, Robin set the car seat back down on the couch. "That would be quite irresponsible of me," Robin agreed. "I suppose you'll just have to wait here for now. You should probably take a nap as well."

Sierra let out a quiet sigh of relief as Robin shuffled away, looking over at the toys once again. She had no idea when Lilly would get home, but she'd bought herself a little time. Squeezing her eyes shut, she channelled all her energy into her summoning spell. It was simple enough to do normally, but without her wand it was far more tiring, and after her spankings she was already feeling quite drained. She opened her eyes hopefully to see if it had worked. The wand wasn't in her hand, or in the car seat with her, but the toy pile had shifted enough that she could see the tip of it there.

Before she could try again, however, Robin walked back into her view. "Zoe is sleeping like a little angel," she said. "Why are you not napping as well?"

"Well, umm..." Sierra fumbled, searching for a good excuse.

"You must be thirsty," Robin decided, unbuckling the harness and pulling Sierra out of the seat. "I can take care of that!" Robin sat down next to the car seat on the couch, laying Sierra face up over her lap as she began to pull down the top of her uniform, revealing that underneath she looked just as realistic as she did on the outside.

Sierra's eyes widened as she realized what was happening, trying to wiggle her way out of Robin's grasp, only for a pair of silver tentacles to spring out of the robot's back, wrapping around Sierra to pin her arms to her side and hold her in place. "No!" she whimpered as she was brought up ever closer to Robin's chest.

"Are you not comfortable feeding from this form?" Robin asked. "I have two more that are capable of feeding." Suddenly, her body seemed to ripple, and a moment later the cheerleader was gone, replaced with a similar looking, but slightly older looking and taller, woman, this one in a nurse outfit. The top was unbuttoned, one side folded back to reveal the open nursing bra underneath. The other side of the top had a pocket, holding a few syringes, a lollipop, and a thermometer.

"No!" Sierra repeated, shaking her head. Again, Robin's form changed, turning a little older still, now in a dress and apron, one that looked exactly like the ones she'd seen the Robo-Nannies in the other dimension wear, though, unlike them, Robin still looked completely human underneath it. "No! I'm not thirsty!" Sierra whined.

"You're not used to this, are you?" Robin asked, patting Sierra's bottom. "According to your records, you've only dealt with the first R.N. model. Us second models have many new features, including a camouflage function to help us blend in on these other worlds. Our research indicated that uniforms tend to make people more comfortable. We are also able to produce our own synthetic milk, which we can customize to the situation as needed. I could add a diuretic to it, for example, but you seem perfectly capable of soaking your diapers on your own." Sierra blushed at the teasing, getting a smile from Robin. "What you do seem to need is help getting to sleep," she continued.

Sierra's eyes widened and she started to open her mouth to protest again, only to be pulled upwards and against Robin's breast. As soon as her lips touched it, she felt her mouth begin to fill with milk. It felt warmer and thicker than Sierra was used to, and slightly sweet, though the thought of what it was, even if it was coming from a fake breast, made Sierra try to deny that it actually didn't taste too bad. She knew she couldn't let herself drink it anyway, or she'd fall fast asleep, helpless to think of a way to avoid being taken back to the other dimension.

She tried to pull her head back, trying to spit the milk back out, but it was coming too fast. She did feel a little dribble from the corners of her mouth down her cheeks, but most of it was getting in. Robin noticed as well, shaking her head. "A messy eater, huh?" With that, yet another tentacle appeared, sliding up over Robin's shoulder, then down towards Sierra's stomach. Sierra glanced down in time to see her shirt begin to raise up off her body towards the tentacle, as if it was being drawn towards it, and then, with a rip, it was sucked inside. Yet another tentacle appeared from the other side of Robin's body, and one of Robin's normal arms reached up towards it, allowing it to drop a large, plastic coated yellow bib with a duck on it into her hand, which Robin quickly tied around Sierra's neck.

"That's usually meant for when babies like you are found in big girl clothes, taking those nasty old things and reforming them into something more appropriate," Robin said, rocking Sierra lightly, "but at least you seemed to realize that you don't belong in those."

No matter how hard Sierra tried, there was always more milk being pumped into her than she could spit out, so she was going to have to try something else. She tried to twist around, to get a better glimpse of the toys, but Robin's tentacles just wrapped around her more tightly. It was going to be even more difficult now, since she couldn't talk around the mechanical, if very real feeling, breast in her mouth, so the spell would have to be both wandless and wordless, a difficult combination in the best of times, even when she wasn't already worn out and being force fed sedatives.

Still, it looked like her only chance, so she closed her eyes again to help her concentrate, her lips moving subconsciously, making more milk dribble down her face and onto her bib. She didn't even notice that she was dribbling from elsewhere as well until Robin patted her bottom and observed, "Someone is a regular little fountain, isn't she?"

Sierra blushed, her concentration temporarily broken, forcing her to start again, trying to push aside all thoughts of the milk she was drinking, the diaper she was wearing and wetting, the robotic woman holding her, her mind focused just on the spell at hand. To her surprise, she felt the familiar, slightly tingly, sensation of magic. A moment later, her hand, still held against her body by one of the tentacles, closed around the handle of her wand.

Her eyes snapped open as she cast another spell, still difficult without being able to talk, but far easier with the help of her wand. She remembered quite well that this kind of technology had seemed to have some sort of resistance to magic in the other dimension, though her magic had just worked worse in general there, so she wasn't sure if that was the cause or if there was some other factor at play. Either way, she didn't want to try doing anything against Robin herself until she could talk again, so instead she cast a spell on herself. She'd used it several times, and she disliked having to do it, but it seemed like her best bet.

In a flash, she shrank, loosening Robin's grip on her enough to let her slide free, jumping to her feet clumsily and backing up, pointing her wand at Robin. "You'd better leave me alone," she threatened. "I'll turn you to scrap metal!"

"If you can't play nicely with your toys, I'll have to take them away," Robin lectured her, the two grabbing tentacles shooting out towards Sierra. She was ready for that, though, blocking them with a hasty, but effective, shield charm.

"Just go away! Tell them you couldn't find me!" Sierra ordered the robot.

"I can't do that, little one," Robin said sternly. "You are going right back where you belong, whether you like it or not!"

Sierra had been using the time as the robot spoke to focus her energies, aiming a magic blast right at the robot's face. If she could damage it enough, maybe it would have to leave to hide what it really was from any outside observers.

Instead of blasting a hole in the robot's head, however, its form merely shifted again, this time shrinking downward to a little shorter than Sierra herself, as a cute little girl in pigtails and a Girl Scout uniform. "Hey, I told you to play nice!" the girl squeaked in her cute little voice, crossing her arms and stomping her foot right before changing back into her cheerleader form.

The grabbing tentacles swiped at her again, and this time her shield spell faltered, forcing Sierra to jump out of the way, scrambling clumsily out of the way. "Stay still!" Robin ordered, but Sierra had no intention of doing that, staying on the move as she changed her tactic, aiming instead at the base of the tentacles where they sprouted from Robot's back, hoping to break them off.

One of the other tentacles unfurled floating across the room not at Sierra, but at the pile of old toys, sucking them up as it's companion tentacle appeared as well, shooting a brightly colored net out of itself at Sierra. She swung her wand, managing to swat it out of the air just in time, making it hit a lamp instead, knocking it over and breaking it.

"Naughty girl! Look at what a mess you made!" Robin scolded her. "Do you need another spanking?"

Robin grabbed for her with the tentacles again, this time coming at her from two different directions. Sierra managed to avoid them, just barely, but she could tell this wasn't going well for her. Maybe she just needed to Apparate out of here once and for all, and hope Robin couldn't follow. As she ducked out of the way of the second tentacle, however, she turned right into the path of a third, one she hadn't seen the robot use before. The end of this one was shaped like a pacifier, which, to Sierra's horror, was shoved into her mouth and immediately began to pump disgusting baby food into her mouth. A strap began to grow from one side of the mouth guard of the pacifier, quickly winding its way around Sierra's head to fasten to the other, attaching itself to Sierra.

"Don't think you can outsmart me, young lady," Robin said sternly, quickly moving in closer now that she had a hold on Sierra. "You're just a baby!" The tentacle that had just spit a net at her moved towards her feet, where it began to spit out more fabric, weaving what looked like a pair of fuzzy pink bunny feet around Sierra's own sock clad feet before starting to move up her legs as it's companion continued to devour the stuffed animals to fuel it. The two grabbing tentacles wrapped around her arms, holding her in place, though she kept her hand clamped as tightly as she could around her wand. Finally, the last tentacle, the one that had filled her diaper so many times that day, came to join the fun, snaking its way back into her pants.

"My rash solution tanks read as 85% full," Robin mused to herself. "There must be some other malfunction with the delivery system. I'll have it checked out when we get home. For now, however, I believe you would benefit more from another function." Sierra yelped in surprise as she felt the tentacle twist in her diaper, moving up towards her sore backside, then narrowing slightly as it pushed its way into her bottom. It slid upwards as she squirmed uncomfortably, then, when it stopped, she felt a rush of liquid begin to pour into her.

"Let's see if we can clear all this naughtiness out of you!" Robin said cheerfully. With all these tentacles working, she looked like some huge, half-mechanical, half-human spider, especially as the one continued to move up Sierra's body, bundling her up in what was now recognizable as a fluffy, footed sleeper, one made to look like a bunny. As it moved up to her crotch, it halted just long enough for its companion to join it over there, sucking the diaper right off of her, only to be rebuilt and reattached as a much thicker version, this one thick enough to force her thighs well apart, before being covered by the bunny sleeper.

With the baby food still flowing into her mouth, she couldn't talk again, but she began to desperately shoot off any spells she could manage at Robin, trying to get her to stop. Most of them bounced off the robot, hitting various things in the room and knocking them aside, but a few of them made the surface of her body ripple in places, like she had when changing shape.

If that had any effect, however, Robin didn't show it, just wrapping her grabbing tentacles tighter around Sierra's arm before reaching out with her normal hand and pulling it away right before the tentacle wrapping her up moved over that arm, making the sleeve of the bunny sleeper, which ended with a thick mitten shaped like a paw. It seemed quite hopeless now as she stood there, held in place, being force fed what tasted like mashed peas, being given an enema while the last touch were put on her new outfit, a big fuzzy hood going over her head with a pair of floppy ears attached. Sierra could see herself in a mirror across the room, and she looked like one of those stuffed animals Robin's tentacle had consumed to make this, other than her face and some of her hair sticking out of the front of the hood. There was even a little tail on the back!

Luckily, just as Sierra thought it was all over, she heard the front door open. Lilly was home! Robin seemed to realize this as well, as she started to retract all of her tentacles, slipping Sierra's wand into her pocket. The tentacle at her face snapped free of the end, leaving the pacifier still in place, ready for Robin to reattach any time she wanted. Sierra gave a little sigh of relief as the enema stopped and that one snaked up her back and out of the neck hole of her sleeper as well, though she was uncomfortably aware of the water Robin had already managed to put into her with it.

The tentacles all retreated back towards Robin, but stopped before sliding back into their hiding places on her back. She frowned, the tentacles bobbing slightly, but still not going any further in. Robin's eyes narrowed as she glared down at Sierra. "You damaged my camouflage circuit, you little brat!"

"Oopsie," Sierra giggled, feeling a rush of pride that she had actually managed to accomplish something with her magic. "What if one of the inhabitants of this dimension sees you like that? Won't that blow your cover?"

Robin gave her a dirty look before rippling into her nurse form. The tentacles snapped back into place in a flash, almost before Sierra could see them do it. Sierra's stomach sank as Robin grinned down at her. Maybe she hadn't done anything after all... When Robin changed back to a cheerleader, however, the tentacles all instantly popped back up, making Robin frown again.

Her shape snapped back to that of the nurse right before Lilly walked in, looking around at the mess the two had made of it in their fight. "What is going on here?" she demanded before turning to Robin, narrowing her eyes as she realized it wasn't the same person she'd left in charge. "Who are you?"

Sierra hoped that Robin would have to struggle a little with that, but instead she smoothly said, "I'm Robin's big sister. She wasn't feeling well and called me to take over."

"That's too bad," Lilly said. "I wish she would have called me, too, to let me know." Her eyes turned to Sierra now, narrowing angrily. "I don't think I need to ask if you were well behaved, now do I? Don't think this cute little outfit is going to get you off the hook, either!"

"It's not my fault!" Sierra squeaked.

"Did Sierra do all this?" Lilly turned to Robin, gesturing towards the wrecked living room, turning back to Sierra after the robot nodded. "I think I believe her more than a bratty little girl like you. This is how you act when I tell you to be on your best behavior?"

"B-But..." Sierra pouted.

"Does your sister need that sleeper back?" Lilly asked Robin, who shook her head. Lilly opened her purse, pulling out some cash. "Well, thank her for for me, it is awfully adotable. And give her this, please. Feel free to take some yourself for your time. I hope she feels better soon. Now, as far you, Sierra..."

Before Lilly could finish her thought, they were interrupted by a sleepy yell of, "Mommy? Is that you?" from down the hall.

"You stay here," Lilly ordered Sierra before heading down the hall.

"All right, Zoe is fine now. Let's get you home, too," Robin said, stepping towards Sierra. Sierra took a few clumsy steps backwards, barely able to even waddle with this hugely thick diaper between her legs. There was no way she could outrun the woman dressed as she was, but fortunately, before she had to, Lilly returned, leading Zoe by the hand.

"Oh, thank you for keeping an eye on her," Lilly told Robin, sounding a little surprised she was still there. "We have some business to attend to, though, don't we, Sierra?"

Sierra gulped, the liquid already in her tummy sloshing slightly as she nodded. She knew she was condemning herself to even more of an enema to be added to that, and likely bedtime right after that. Still, it was better than giving Robin any excuse to stay and possibly find another chance to snatch her away.

Robin, sensing that she was being dismissed, frowned at Sierra, seeming to be searching for some reason to stay without blowing her cover, then finally just said, "I hope you'll give my sister another chance! She felt so awful having to leave early! And even if she's not available, I'd be happy to help out!"

"Okay!" Lilly smiled and waved as the robot retreated. Once she was gone, though, she said, "I don't know about that! Just look at the mess those two let Sierra make!"

Sierra's mind raced as she processed those words. Robin still had at least two other forms Lilly hadn't seen, so even if Lilly never called her again, there was a chance she'd find another way to take her. But there was no telling when or where that would happen... And, unfortunately, as much as Sierra didn't want it to happen, she had to see Robin again, if only because the robot had taken her wand with her. She wasn't sure how she would get it back, but the longer she was around her, the more chance she would have of figuring something out, and the best way of making sure she was around was to have her as a babysitter.

"It's not their fault!" Sierra said reluctantly. "Don't blame them! This was all me! They were both really nice!"

Lilly seemed a bit surprised at the words. She smiled down at Sierra, patting her on the head. "That's very mature of you, taking responsibility like that. It isn't going to get you out of your punishment, though. Now, Zoe, would you like to get get the enema bottle ready?"

"Yeah!" Zoe giggled, racing off down the hall excitedly. Lilly took Sierra's hand and began to follow, Sierra having to go much slower with the diaper she had on. By the time they reached the hall, Sierra could already hear the water running in the bathroom and blushed, hoping Zoe didn't fill the bag too full. For a moment, she wondered if she had made the right choice not just letting Robin take her, but, as humiliating as it could be from time to time, she knew this was much better than that other world. She would just have to hope that she could come up with a plan for outsmarting that robot before she came over to babysit the next time... And that Zoe would be less of a meanie while playing with her from then on.

That second hope was quickly quashed as she was taken back to her crib, tummy even fuller now - though not from supper, which she was being sent to bed without, though she'd already eaten more than enough baby food - and cramping from the cool water Zoe had filled the bottle with. Zoe had gotten only a slight reprimand and a reminder that warm water was better when Sierra had complained about it, batting her eyes and claiming that she had forgotten. Between that and the sight of the toy box, sitting there open, heart shaped paddle sitting on top of the other toys, Sierra was sure that things weren't going to be getting any easier for her here.

As she squirmed on the mattress, bottom still sore from her spanking, fighting hard not to fill the huge diaper under her bunny sleeper, she wondered if maybe she could find a way to make Robin take Zoe with her to the other dimension instead. The thought of the other girl living with the Cases, and especially the spoiled, bratty Madison, made her giggle, right before she reached back to rub her throbbing rump, barely able to feel it through her diaper, remembering the trouble she'd gotten into for laughing about Zoe's misfortune last time. Still, it couldn't hurt to dream about it, and, as Sierra snuggled up, the sedatives and the long day she'd had finally catching up to her, that was just what she intended to do.
