Ronan grumbled softly under his breath as she tugged a backpack full school work over one shoulder while making his way over to his best friends place. The fact that the school work was all done didn't matter as it had mostly been used to escape his own place where it had been currently just him and his big sister (who was ironically named Grace when she had none) home, till one cup of cheese attack too many made him decide to bail. 
'Honestly, catching a fart in her hand and putting it in my face at her age! I thought she was 15 not friggen 5!' The 10 year old mentally huffed, then thought about it. ' Heck, even younger! Felix is -4- and he's more mature then her!' 
the thought of his best friend Ellie's little brother being more mature then the bully that called itself a sister make Ronan smirk a little, and his mood ever so slightly lightened up a bit as he came to Ellie's front door and rang the door bell.
He didn't have to wait long for Ellie to opened the front door up, though she only opened it up part way, guarding the entrance with her body.
Slightly taller then Roan, who was 4'9 to her 4'11, Ellie had orange hair that while some would call messy, it more made her look like she had walked out of a anime. Combine that with her green eyes and fun loving always happy attitude, and there were days that Ronan had to wonder if she really WAS a escaped anime charter, gracing the real world. 
Then again with his own spiky black hair and grey eyes he could semi be accused of the same thing, though he was more stand offish, and anti social since Ellie and Felix were his only real friends. 
"Hey, this really isn't a good time right now, if you had called first I would of told you and saved you the trip." She said quickly, looking genuinely sorry. 
"Ah come on, please let me come in? Grace is being a total rhymes with witch and I need a place to escape to till mom and dad come home. Plus I figured hanging out with my bestest and my semi little brother from anther mother would help perk me up!" Ronan pleaded. 
"And any other time I would say come on in, but it's really not a good time." Ellie said again. 
"Pleasssse, Haven't we been best friends since we were in diapers? Help a brother out!" Ronan tried again, figuring playing the longtime friendship card would help.
"Look, I told you that.. I.." Suddenly it was like a lightbulb went on over Elie's head, and she broke into a bigger grin then usual (which was saying something!) and grabbed onto his arm. "Actually you know what, you CAN come in! I need help with something you're just perfect for it!"
Yelping as he was tugged in, Ronan raised a eyebrow and went to ask what was going on, but then before he could Felix walked onto the scene, and it looked like the poor little guy had been crying. 
only coming up to about Ellie's belly, and still having baby fat in places like most four year old's, he shared his sisters green eyes and orange hair and normally had just a big of a grin as she did, but not today. 
"Hey buddy, you feeling any better?" Ellie asked, letting go of Ronan and dropping to one knee, moving to give him a head pat but the little guy turned away. 
"Nnn.. Gonna go ta my room.." he muttered and walked off, closing his door.
"..Ok what's going on wi-" Ronan started to ask, but got a hand over his mouth and Ellie put a finger to her lips, then pointed upstairs where her room was. 
Knowing better then to bother trying to ask, Ronan nodded his head and followed her up the stairs. 

Once they were safe in Ellie's room, and she had turned on some music to cover up what they were saying, she started to explain. 
"Sooo you know how there was a semi thunderstorm today right? like it made all the noise and some flash's of light but no rain and went away before anything really happened?" Ellie asked. 
"yeah, I was there in class with you when we all heard it." Ronan said dryly. 
"Wellll... Normally Felix is ok with thunderstorms, he's a pretty cool and brave kid that way.. but see he was waiting in line to use the bathroom when when of the thunder claps happened andddd.." Ellie trailed off.
"Oh crap.. Was it just pee at least?" Ronan asked, feeling bad for the little guy. 
he could recall having more then a few close calls himself back in pre school and even in kindergarten. 
"Well yeah, but still he totally flooded his pants and all the other kids were laughing at him and called him tinkle pants and the like for the rest of the day. Now he's all depressed and says he feels like a big stupid baby." Ellie sighed, moving over to her computer desk and putting a hand on one of the drawers.
"Well that's stupid! he's the coolest little kid ever!" Ronan huffed, getting a little worked up now. "If there's anything I can do to make him feel better, just tell me!"
"I'm SO glad you said that!" Ellie said, getting a HUGE grin on her face. "I actually DO have a plan in mind to make him feel super duper grown up and cool. I was gonna do it myself but with two of us it'll go even better!" 
"heh, Ok, so what's the plan? we let him kick our butts at video games? let him watch cartoons meant for older kids?" Ronan asked.
"nah, well yeah, Maybe those but my main plan is nice and simple! we'll make him feel like a super cool big kid in his underoo's because WE'LL be rocking these!" Ellie said then opened the drawer and pulled out a thick white with a nursery print on it diaper. 
"...when I said I'd do anything.." 

Felix whined softly, laying on his tummy on his bed, listening to some music but not even the magic of sing along with micky 5 could get a smile on his face and h pulled a pillow over his head, trying to think about just how he was gonna be able to face everyone at school tomorrow.
it had already been made clear to him that he couldn't just quit school for forever and half, and not even just for forever when he'd try to bargain it down. He had thought he was being super reasonable but his mom didn't share that sentiment and had made it clear he was going to school before she had taken off for her job.
Switching the music off he paused as he heard Ellie and Ronan arguing upstairs, making the little guy slowly sneak out of his room and creep up the stairs trying not to be heard. As it turned out though, all of his stealth had been pointless as the pair were still arguing too loudly to hear him coming up. 
"Remind me again why I agreed to this?! You've had a LOT of dumb ideas, but this one has to not only take the cake, but went and opened a cake shop!!" Ronan was saying, huffing and crossing his arms over his chest. 
"What does that even mean!?! I mean.. Really! I think you're just grumpy because you need some juice!" Ellie huffed back, crossing her own arms and turning away from Ronan and locking eyes with Felix, a blush coming over her face and she tugged on the front of Ronan's t-shirt. 
"So um.. How long have you guys been wearing diapers?" Felix asked, giggling a little and grinning, rocking back and forth on his heels.

Ronan gulped, they hadn't had time yet to decide just how to spin this, in fact that had been what started the whole semi fight with Ellie anyways.  He'd been annoyed that AFTER he'd put the stupid diaper on, THAT was when she revealed she hadn't thought of a way to expose their diapered butt's to Felix yet. 
"Are you kidding me?!? That's kind of a big part of this!!" He'd huffed.
"Oh excusssse me! I just thought being diapered first would help us think better mister 'I'm-always-right'"! She had shot back.
The argument had escalated from there till they were in the hell and now, were stuck like deer's in the headlights.
A quick look over at Ellie told him she was coming up dry when it came to ideas, and with the clock ticking Ronan just jumped in, figuring he had nothing really to lose. 
"O-Oh poopies! You caught us! Ellie I told you we should of stayed in your room! Now your awesome little brother knows all about us!" Ronan whined, tossing in a extra touch of grumpy toddler.
"Wait.. what?" Felix asked, wrinkling his brow and tilting his head.
"Oh shuck's.. Ronan's right.. well.. I guess there's no choice but to come clean." Ellie sighed, picking up on Ronan's idea and running with it. "Felix, Me and Ronan have been TRYIING to tell you this for awhile, but well, like the big dumb babies we are we couldn't figure it out before you just caught us in our undies."
"uh.. but those are -giggle- diapers not undies!" Felix pointed outa big silly grin on his face while looking at the to blushing 'big kids'.
"well see.. about that.." and Ellie looked over her shoulder to Ronan, silently asking for help.
"We've secretly been.. Babies this whole time!" Ronan said, having never really excelled at improv though he was doing better then most would of in this situation. 
"..Wait that's a THING!?!" Felix asked, his smirk turning into a look of amazement. 
"O-Oh yeah! Me and Ronan never really grew up! we still need diapers and the whole nine yards!" Ellie said, taking a step back and putting a arm around Ronan.
"It's more common then you think. lots of grow-up are really still big babies." Ronan quipped, smirking a little and getting a slight elbow from Ellie not to go off track.
"Actually that makes a LOT of sense! seen LOTS of people on the shows mommy watches that are always bawling soo.." Felix said, smirking and giggling again. 
"W-we've been hiding it from EVERYONE from years and ... and now you know and.." Ellie said, starting to fake cry and anther elbow got Ronan joining in, both of them rubbing their eyes and doing their best sobbing voices. 
"Wahhh! we're just big stupid babies who go potty in our pants all the time!!"
It was safe to say they were never going to win an award for their acting, but then again the only person they had to fool was Felix, who thankfully wasn't a critic.
"H-Hey! it's ok! I still think your both super duper neat!" Felix said, rushing over and giving them both hugs, and then making them both super blush as he patted their diaper butts.  "And dun worry! your diapies are still clean!"
"O-Oh thank you for uh.." Ronan squeaked out, looking at Ellie, a mixture of utter embarrassment on his face and a scowl at her for getting him into this.
"Checking! us big dumb babies don't always know.. actually.. could you pleasssse look after us? I think it would help us out TONS to have a big kid like YOU looking after us big babies." Ellie said, likewise blushing but in for a penny, in for a pound.
"heh, Of course! Come on, let's go git some cartoons on for you too!" Felix said, leading the way.
'...I'm totally just going to the park next time I wanna escape my sister.' Ronan thought dryly.

Heading down the stairs and getting into the living room, Felix had a ton of questions that he asked rapid fire. Knowing that Ronan was already having all the regrets (Ellie was having a few herself) she fielded the questions as best she could.
"isn't it gross sitting in stinky diapers?" 
"W-well when your a big helpless pants pooper, you kinda get used to it."
"How do you guys manage to hide their big puffy diaper butts so well most of the time?"
"Years of practice, though it wasn't always flawless, like today for example."
"If you've always been a big baby, how come this is the first time I've looked after you, and why does mommy always get you to babysit me?"
"uh, you've been totally misreading it the whole time. You've been babysitting ME for years! This is just the first time I've asked you to be more hands on. It's been soo cool and awesome you were hands off but clearly we need a BIG KID to show us the ropes."
The answers seemed to satisfy Felix, at least for the moment, and he spread out a semi thick and comfy blanket on the floor of the living room for the big babies to sit on. Turning on the tv and putting it on treehouse (all day pre K shows) he ruffled both Ellie's and Ronan's hair (which admittedly had both of them grinning like fools) before telling them to be good while he went and got them toys to play with.
With Felix out of the room Ronan gave Ellie a death glare.
"Jeez, could you of made us sound any more babyish?" He muttered softly.
"Well i didn't hear you chipping in with any details." She snickered and stuck out her tongue. "Maybe chip in next time if you wanna modify our cover story." 
"...there's SO not gonna be a 'next' time." Ronan huffed. 
"Cute that you think so.. don't you think it'll be wear if your not diapered every time you come over now for the next few visits?" Ellie said, a HUGE grin on her face. 
"..Ah poopies." Ronan groaned louder then the quiet talk they had been doing, right as Felix came back with a basket of toys.
Felix quickly set the toys down and came over, sniffing the air.
"Hmm, I don't SMELL any poopies Ronan, but you better stand up so big bro can check yer butt!" Felix said, thinking Ronan had been declaring he was going in his diaper.
"heh.. yeah Ronan! stand up and let my AWESOME big bro check your diapie!" Ellie said, a hand going over her mouth to hide her grin. 
"..Yeah ok." Ronan huffed, any fight going out of him since it wasn't like he was actually stinky or anything and it was all for a good cause. 
A couple of pants on the butt and the back of the diaper being tugged open (though Ronan had to bend down slightly for Felix to get a good look) and the 'big baby' was declared clean, Felix giving his butt a couple of extra pats.
"It was likely just a toot, but your a good boy for asking for a diapie check!" the little guy said. 
"..Oh yeah. I'm just the best." Ronan said, blushing big time and looking away. 
Thankfully sarcasm still mostly sailed right over Felix's cute little head.

Half a hour of TV time and playing with toys later, and all three of them were getting hungry, though it would be Ellie's petite tummy that announced it the loudest with a very unlady like growl. 
"heh, are the babies hungry?" Felix asked, giggling and walking over, patting his sister head. 
"Well maybe. just a touch." Ellie said, blushing lightly from the growl. "but there's a problem.. we're big babies and don't know HOW to make or get food!"
"oh don't worry about that! Mom left phone for pizza and heh.." Felix smirked and run his thumb under his nose, striking a cool guy pose then jerking a thumb at his chest. "I know how to use the phone AND our address!" he said.
"Oh wow! Koolies!" Ellie gushed. "the only phone I know how to use let's me talk to Micky mouse!"
"I know my address too!" Ronan said, deciding to get in on the goofy fun. "It's 1 2 3 mommies house!" 
"heh.. of course it is." Felix giggled. "you two play nice while I go order us a couple of pizza's, Ok?" 
"Whoa, a super cool baby sitter AND pizza? can this day get ANY better?" Ronan asked.
"I really don't see how." Ellie replied, the pair winking so only they could see. 
the effect was clear on Felix who strutted out feeling like the coolest big kid ever while making the phone call.
"..Think we're hamming it up too much?" Ronan asked in a whisper. 
"Nah, if anything I wanna go even more hammy! full on porky pig!" Ellie giggled. 
"..what does that even mean? you gonna start stuttering? and If I didn't know any better, I'd say you like playing the part of a big baby." Ronan lightly teased. 
"heh. who doesn't like being spoiled. And your out doing me by shades mister 1 2 3 mommies house." She pointed out. 
"heh.. ok fair. i-" Ronan started to say but then spotted Felix coming back in. "Are you kidding me? Paw patrol is WAY better then Dora the explorer!!"
"Pffft, in your dreamssss!" Ellie said, without missing a beat. "Dora cou-"
"hey now you two, no fighting! I don't wanna hafa put you on time outs!" Felix said, hands on hips. 
"eeep! we'll be good!" Ronan yelped 
"Sorry big brother!" Ellie chimed in.
"it's S'ok. Maybe that's enough tv for right now.. how would you two like me to read you a book while we wait for din din?" Felix asked. 
the pair exchanged a look, neither of them knew that Felix could read but they didn't wanna bring that up and derail the little guy after all the work they had put into making him feel big and cool.
"That would be great." Ronan said, giving a reassuring smile. 
"Oh boy! story time! But you'll have to pick the book. us big dumb babies can't read ya know." Ellie said, hamming it up once again. 
Felix furrowed his brow for a second making Ellie and Ronan tense up, worried that they had blown it after getting THIS far. 
"Huh, Makes sense. Ok. you two get comfy and grab a stuffie, I'ma go and git a story!" Felix said and dashed off. 
"..This is gonna be painful isn't it?" Ronan whispered to Ellie.
"It might not be.. mom reads to him a lot.." She said, but didn't look totally convinced.
Felix came back to the pair sitting on their diapered butts and Ellie hugging a brown teddy bear while Ronan had been left to pick between a pink hippo or a antimorphic heart (likely a prize from a heart based charity fair the family had gone too) and in the end went with the hippo because the heart freaked him the feck out.
Felix took a seat on the couch and got read to read, holding one of the text only story books that their mother favored and.. it quickly became clear that the little guy couldn't read and would be reciting the story from memory as he was holding the book upside down.
"Once upon a time, there was a magical kingdom.." Felix started and Ronan glanced at the clock on the wall, praying and hoping that the pizza place lived up to it's quick delivery slogan. 

25 LONG minutes later (As whenever Felix forgot exactly what was suppose to happen between too events he would add lib so Snow white and seven dwarf's now stared characters from paw patrol) the front doorbell rang and Felix set the book down on the table. 
"You guys sit right there, I'll go and handle this." he said with a pride on his face as he scooted off the couch and snatched up the pizza money.
Waiting till he was out of ear shot Ronan shot a glare at Ellie then started to whisper. "You owe me the last 25 minutes of my life back, with compound interest for how long it actually seemed!"
"I don't know what your going on about, that was the most entertaining version of Snow white I ever heard! who knew a four year old could be such a good storyteller!" Ellie whispered back, a look of pride on her face that was replaced by a look of oh crap. "A four year old.. who we just sent to answer.. the door.. with money.."
"..Oh crap!" Ronan yelped. 
The pair scrambled to their feet and dashed towards the door where a tall blond woman who was somewhere in her 20's was listening to Felix tell her all about what a big boy he was, and how he was babysitting two big babies.
"Oh, these must be the little cuties right now." She said, a look of amusement etched on her face and a twinkle in her eye. "Cute diapers little ones!"
Instantly Ronan and Ellie were blushing SUPER bad and Ronan found himself being used as a shield of sorts as Ellie hide behind him, going for quick peeks over his shoulder.
"...Really?" Ronan asked in a deadpan voice. 
"hey, I thought I told you two to go and wait for me!" Felix said, turning around and putting his hands on his hips and shaking his head, then his left index finger. "Bad babies!"
"Now now, don't be TOO harsh with them." the pizza lady said. "I bet the big babies just missed you and wanted to help.. Right?" 
She gave a wink to the kids that Felix missed and Roan and Ellie instantly jumped on board, nodding their heads.
"Heh.. well ok. I'll let it go THIS time. but next time I'm babysitting." Felix said and turned back to the Pizza lady to hand off the money and get the pie. 
Ronan and Ellie exchanged looks, silently mouthing 'next time?' to each other, spotting a big flaw in the plan. 
"Uhh, Felix, since you called it in and paid for it, why don't you let Ronan carry the pizza? that way we can say we helped out with supper too!" Ellie suggested. 
"Well.. Ok.." Felix said and nodded to the pizza lady who started to hand the pie over to Ronan who had waddled forward. 
"Carful little guy, it's hot." the lady said, milking this for every moment it was worth. "Make sure you let your babysitter hand out the slices ok?"
"I will." Ronan said, rolling his eyes as Felix was busy walking over to Ellie now. 
"Pinky swear?"
Ronan shot the woman a death glare that was negated by the fact he was in huggies, and got the pinky swear over and out of the way, kicking the door shut as she left. 
'I'm never gonna be able to order from there again.' He thought, trailing behind Ellie and Felix as they headed for the dinner table.

Of course if Ronan had assumed the torture was over with just getting the pizza, he had sadly underestimated the depths that Ellie had gone to to keep up the big baby act.. and maybe how much some divine power out there must hate him. 
As the trio went to take their seats Ellie spoke up. 
"Oh Felix, I know you're gonna have a can of soda cuz that's what big kids do.. but can you get me and Ronan's ba-ba's out of the fridge? we can't be trusted with big kid cups like you after all." Ellie was smiling sweetly at her little brother but also soaking in the shocked look on Ronan face.
'I swear, if it wasn't for the fact I'd likely just keep missing till i hit a table leg I'd kick her right now..' he huffed mentally but once again, in for a penny..
"Yeahhh last time I tried to use a cup I just soaked my face with it and had Kool-Aid in my diaper! Was really chilly!" 
that got a giggle from both Ellie and Felix. 
"Oh! and don't forget our bibs, their in the bottom drawer by the fridge!" Ellie called as Felix went into the kitchen. 
'..Just how far out do you have this planned?' Ronan mouthed at Ellie, who just smirked and pretended not to understand him.
The bibs turned out to be your basic white Snap-on's, and the baby bottle were filled with cherry juice which Ronan loved so it wasn't TOO bad sucking on them, ever if they were semi teddy bear shaped. 
Thankfully with pizza being a finger food Felix hadn't tried to insist on cutting it up for them because neither of them were gonna let the little guy use a sharp knife, as as they munched and drank, Felix naturally had even MORE questions for the pair.
"So, if you guys can't read how do you do your homework?" He asked.
"Oh well.. that's easy. we just scribble lots of stuff and then put on our best 'we're so cute!' faces when we turn it in to our teacher and she takes pity on us."  Ellie said, making sure to get some sauce on her bib and face. 
"heh.. I'd like ta see that! ...So are the other kids in your class big babies?!" he asked, eyes going wide.
"Uhhh Nope! just me and Ellie! but ya know.. it's a whole no child left behind think so while they're learning math and stuff we're in the corner blowing spit bubbles and.." Ronan trailed off, trying to think of something and then blurting out. "Doing the diaper dance!"
"The diaper dance?" Felix asked, looking at Ronan with a HUGE grin on his face. 
Ellie mouthed 'the diaper dance?' at Ronan, a look of confusion on her face, though she quickly returned to smiling as Felix turned to her. 
"Can you two show me the diaper dance?" he asked, sounding excited and bouncing in his seat a little.
"Oh well, we could but.." Ellie started, desperately racking her brain for a excuse. 
"If you wanted to see it you should of asked before dinner Felix. It's a whole lot of jumping and shaking our butts and with full tum tums we might get icky tummies and up chuck. And I know you wouldn't wanna make us sick." Ronan said, dazzling himself with his brilliance. 
"Oh yeah! I didn't think of that! Of course big babies like you guys would have sensitive tummies!" Felix said, the pair exchanging a smile. "I'll just git ya to do it next time I babysit before you eat!" He said and went back to munching, pleased with how clever he was and not seeing the big babies exchange worried looks again. 

After supper the trio headed for the living roof and watched some tv, Ellie noticing how Felix was starting to get a little droopy eyed and she nudged Ronan who nodded, getting the drift. 
Both of the big babies started fake yawning like crazy and laid down on the floor by Felix (who had come down to keep a better eye on them..it wasn't because the blankie on the floor looked SO soft and comfy!) and Slowly but surely the pair 'fell' sleep, eyes closed and breathing softly while staying still which wasn't really easy because Felix had insisted they finish their bottles.
'come on come on go to sleep before I wet my huggie!' Ellie was mentally pleading with Felix who thankfully picked on the psychic plea (who had just stuffed himself too much and was in a food coma, at this point Ellie wasn't picky) and the little guy zonked out.
As quickly but as quietly as the pair could, they slowly got up and waddled out of the room, making a dash for the bathroom and getting to it at the same time.
"Ladies first!" Ellie hissed. 
"I wore diapers all afternoon for you, I'm calling dib on first pee!" Ronan hissed back.
"..Fine but if I wet myself  y-" Ellie started to threaten but Ronan was in the bathroom and the door was shut, leaving Ellie doing the potty dance. 
"Cross your legs, do a dance.. that's the way to keep dry pants!" 

With both of them having relived their bladders and their diapers still dry, they made their way upstairs to Ellie's room to go and get changed. 
"So.. you thought about how your going to explain this when he talks to your mom about it?" Ronan asked.
"Eh, he'll hopefully just think it was all a dream. if not.." She paused and shrugged. "I'll cross that bridge when I get to it. I gotta say though, I feel like the BEST big sister ever!" she beamed, pausing a beat since she was still padded. "..Despite what my current attire might say." 
"Heh.. yeahhh I gotta say, I feel pretty awesome too for helping the little guy feel better about himself. it's kinda weird but after awhile I almost forgot about what i was wearing." Ronan admitted, rubbing the back of his head. 
"Oh? Does somebody wanna snag some of the left over diapers and take'em home?" Ellie teased.
"Yeah no thanks. I only said they semi felt normal, not that I was gonna switch to Huggies for my undies of choice. I'm a underoo's guy all the way." Ronan snorted and stuck out a tongue. 
"well if this is the last time I'm gonna have you padded.." Ellie said and picked up her cell phone. "Wanna do some selfies?"
"..You know, every time I think this can't get any weirder.. fudge it. why not!" Ronan said. 
Logically he knew he'd be safe because he was going to make sure that she was in every picture.
For the next five minutes the pair of diaper dorks did pose after pose, Peace signs, Ronan acting like a damsel in Ellie's arms, one each with one of them holding a nose and pointing to the back of the others diaper.. just cute and funny poses till the last one where Ellie surprised Ronan with a big smooch on the lights that apparently shut down all the higher functions of Ronan's brain.
Giggling and babbling in semi gibberish, he picked up back pack and slid it on.
"I Uh.. I had a really great time today.. we should totally do this again sometime!" the love dazed boy giggled, making his way out her bedroom door while Ellie looked on amused.
She silently counted down from five and then Ronan dashed back into her room, crimson faced and shutting her door behind him.
"So, were you almost out the door before you realized you were still diapered and not wearing pants?" She asked cheerfully, holding his undies and pants up. "You MIGHT wanna put these on if you don't wanna give your sister fuel to torment you till the end of time and six months longer." she giggled and turned her back so he could get changed in semi private. "Don't worry, Next time I'll warn you sooner." 
Ronan blushed but smiled, somehow a next time suddenly didn't so bad. 

The end
