The Worst

A vile stench sent Adagio tumbling awake. Pulled to the world of the waking, her nose was wrinkling without permission when she opened her eyes. When she caught her first waking whiff, she nearly gagged.

“Ohhff.” She clapped a hand over her nose. “What the heck?”

She finally moved her body, now wide awake thanks to the assault on her senses. Adagio was about to wonder where that smell was coming from, but the universe decided to answer the question for her.

squish.

She shuddered. A cold, slimy sensation pressed against her backside. It even sloshed to her inner thighs. It felt gross and clammy, and concentrated near her hips. Almost like it was...

Oh no.

Adagio threw her sheets off. Just below her red satin nightie was the diaper she’d been allowed to forget about for three glorious seconds. It was brown.

“Aw— Uuugh!” She sat up, and cringed as her butt sank deeper into the mess she’d made. “You’ve gotta be kidding me!”

She’d soiled herself in the night. Not quite the first time this something like this had happened. In the past week since losing her gem she’d woken up to wet sheets. But pooping herself? At least she’d never had the displeasure of waking up to that before.

Good thing she was wearing a diaper, otherwise the mess would be a lot worse.

Adagio paused and shook her head. She couldn’t believe she’d just been grateful for the stupid thing around her waist.

Muttering some choice words under her breath, she slowly shifted her legs to the edge of the bed. Each movement sent her mess jostling around in her diaper, forcing her to freeze and wait for it to settle against her skin before she tried again. Eventually her legs made it over the bed, and touched down on the floor.

Adagio pushed herself up, spreading her legs even wider than the diaper demanded. She wanted her mess touching her as little as possible. Forced into the widest waddle of her life, she toddled to her bedroom door and pushed it open.

“Sonata!” Adagio called out into the house. “Get over here now!”

No response.

“Sonata!”

Still nothing.

Adagio shot a glare at her clock. It was half past nine. Was Sonata just not up then? She was usually the light sleeper of the bunch, though.

Growling, Adagio shuffled into the hallway and down to Sonata’s room. Though her diaper’s stench was overpowering, Adagio still detected a hint of pee in the air. Briefly she checked to see if she at a wet spot as well, but no. Just brown, lumpy, bulging padding.

She shivered in disgust. The smell still permeated her surroundings, and she pinched her nose trying to avoid it.

When she reached Sonata’s room she pounded the door. “Sonata, wake up already! I need— uh… I need your help!” The other side of the door didn’t answer. “Stupid, ditzy, idiot,” Adagio grumbled, all but kicking the door open.

Sonata wasn’t inside. Her neatly made bed told her she was long gone. And to make matters worse, the baby bag with all the changing supplies was nowhere in sight.

“Gotta be kidding me,” Adagio groaned. Of all the things to be missing… Now she couldn’t even change herself if she wanted to.

Adagio spared another glance as her mutilated padding. It sagged between her legs; the sheer size of her mess was immense. If she had to go again this diaper may not survive. And she couldn’t go without one either.

“SONATA!” She shrieked, desperation creeping in her voice.

Her best idea was to try and peel the diaper off herself and just sit on the toilet until the other Siren heard her calls. But what if she was outside? Or if she went into town? Adagio may sacrifice the whole day in fear of her bowels.

Wincing, she looked down at her mess once again. It was big…

Okay… I probably don’t have any more left in me, she reasoned. Her stomach growled with morning hunger, confirming that theory. In that case, there was no need for her to sit on the toilet, waiting.

But should she take her diaper off?

Adagio cringed. The feeling of poop against her hips… It made her shudder. And the stench was so powerful. Even with her nose pinched shut she could taste it in the air. But still, just ripping it off would only cause the mess to go to the ground. And then what, clean it up herself? No thank you.

She needed someone to change her, as utterly disgraceful as that fact was.

“Great…” Adagio resigned. Her stomach growled again. She couldn’t deny the emptiness in her stomach. With Sonata gone a change was nowhere in sight. Maybe she should just get breakfast.

In a dirty diaper?! Her mind screamed. Seriously?

She sighed. Both at how repulsively humiliating that was, and at how common it could become given her new lifestyle.

Her stomach growled one more time, rivaling her screaming from earlier. She couldn’t deny it any longer; she needed to eat something.

Stupid human body. Adagio stomped awkwardly to the stairs. Why did she have to live like this? Forced to eat every couple of hours only to wind up with the disgusting situation around her waist. It was the most demeaning thing she’d experienced in a millenium. And that included being defeated by Starswirled the Bearded and Sunset Shimmer.

Sunset, she growled mentally. She would never forget the source of her suffering. Sunset Shimmer and her friends were the reason the Sirens were stuck like this. Incontinent, diapered, powerless. It was an injustice above all others. One day, Adagio would make them pay for that.

But first, she was going to have the find a way downstairs in her dirty diaper.

Adagio cringed at the flight before her. She hadn’t considered it before, but going down with her diaper in the state it was was going to be… challenging.

Hesitantly, Adagio spread her gait even wider than she already was, and forced herself to take the first step.

squish. squish.

Her diaper enjoyed itself. Adagio did not. She slowly brought her other leg forward for round two.

squish. squish. squish.

Adagio bit her lip, body wracked with shudders. It was so slimy and gross! She couldn’t keep this pace up if this was how it was going to be. Taking a deep breath, Adagio darted down the rest of the staircase.

squish. squish. squish. “Eww, eww, eww!” squish. squish. squish. “Eww, eww, eww!” squish. squish. squish.

Her face was tied up in knots by the time she reached the first floor. Her jostled diaper took its sweet time settling down. All the while she hissed and cursed in disgust.

“SONATA!” Adagio screamed one last time, just in case. If there was any chance she could get out of this stupid thing now, she would take it.

Unfortunately, the silence didn’t make that likely.

Grumbling, Adagio toddled onward. The stairs spilled out into the living room, with the kitchen was adjacent. She didn’t have far to go, but even a short walk in her diaper felt like a marathon.

When she finally waddled into the kitchen, a sticky note on the table caught her eye. She shuffled over to it, wincing all the way.

Hey girls,

I’m out picking up more baby supplies. I can’t believe how much I forgot last night! Don’t worry, I’ll pick up some El Locos Tacos for lunch. See you soon~

Sonata

PS I brought the diapers with me. Sorry! Just had feeling I’d need a change before I got to the store.

Adagio crumbled up the note. So that’s where she was. “Idiot.”

Of course, just take off for who knows how long with the only diapers they had. Brilliant idea, it’s not like she would need a change come morning or anything.

Adagio angrily threw the note across the room. It smacked uselessly against the fridge. She couldn’t believe this; if Sonata was picking up fast food for lunch that meant she wasn’t expecting to get back until noon. Or maybe even later.

It wasn’t even ten. Was Adagio really expected to wait around in a dirty diaper for hours?

“Stupid freaking idiot!” She yelled. Sonata was going to get it when she got back. Adagio didn’t know quite what she had in store, but it was going to be something alright.

The crappiness of her situation was really beginning to sink in. In more ways than one. Adagio affixed a scowl to her face and stomped around the kitchen. Patiently waiting around for a diaper change was her only option, but it was also the worst thing ever.

“Forget it,” she grumbled, her empty stomach rearing its ugly head again. “Just forget it.” She couldn’t deal with this right now. Adagio settled on getting her breakfast ready; it was the reason she came down here in the first place, right? Her trip downstairs was not going to be in vain.

She toddled around in order to throw something together. Grabbing a bowl, cereal from the pantry, and milk from the fridge took her all around the kitchen. She ended up filling the room with her stink and the sounds of her squishy diaper. “Ugh.”

Eating wasn’t any better. The smell of her mess was overpowering compared to the taste of the cereal. Even plugging her nose again didn’t do much good.

I’ve gotta figure out how to hold it, Adagio thought as she chewed. And soon.

But how was she supposed to find the time? After the Battle of the Bands, the three Sirens had been forced to make a deal with Principal Celestia. She wouldn’t have any charges pressed against them, but they did have to attend school until they graduated. Plus detention. Every. Single. Day.

And missing just once better come with a good excuse; Celestia had made it clear she wouldn’t hesitate to hand them over to the authorities. So it was school five days a week, plus detention until five thirty. Pile on the homework they were obligated to keep up with and it left them very little time during the week to get potty trained. The deck was rigged against them now.

Curse those Rainbooms for shattering their gems. One good song would’ve gotten them out of all of those punishments. Of course, if they did have their gems then even this incontinence wouldn’t be a problem. But all that remained of them was the handful of tiny pieces Adagio had managed to recover from the stage. Useless.

And that brought up the question of what they could do without their gems. Over the past millennium trapped in this world they had done a lot. They’d hypnotized their way to fortunes and spent their way through them dozens of times. Saving money was something they rarely did, but Adagio did keep an emergency fund spread out through a couple of bank accounts. They might’ve had something like seven or eight million dollars between them all.

Even after all these years she didn’t understand this world’s economics all that well. Adagio was still pretty sure what they had was a lot. But was it enough? Without their gems she had no idea if they were immortal anymore. Maybe for three normal lifetimes that was enough. But if they kept on living forever, they’d eventually run out. And how would they ever make money again the way they were now?

Adagio pulled herself out of those depressing thoughts. She realized she’d been swirling her spoon around in the bowl, not eating. The remaining cereal was all soggy now, drowning in milk. Gross.

Her diaper squished as she took a step back and she cringed. Grosser.

She left all those unanswered questions for another day and poured herself a new bowl. Adagio could only focus on one horribly dismal fact of their situation at a time. And right now, that meant her dirty diaper.

Footsteps suddenly drew her attention. Aria soon appeared from around the stairs, sporting a yawn. And a clean diaper.

Adagio glared enviously.

“Morning,” Aria yawned out. She froze halfway into the kitchen, and sniffed. “Uoough!” Covering her nose, Aria backed up. “What’s that smell?”

Adagio ground her teeth. She couldn’t believe she had to deal with this too. “Nothing.”

“That’s not nothing,” Aria groaned. “Geez it smells like—”

“Don’t say it!” Adagio hissed. Her face must’ve been pink. She could feel the mess in her diaper settling, squelching against her thighs. A disgusted shiver ran down her spine.

It didn’t take Aria long to put two and two together. “You crapped your diaper.”

Pink became red. Adagio didn’t know quite what to do with her hands, eventually crossing her arms. “Y-You—!”

Aria cackled. “Who’s gonna be telling Sonata about her ‘poopy diapee’ now, huh?” She laughed so hard her hand left her nose. Then gagging at the stench cut her off. “Ack! Why hasn’t she changed you yet anyway?”

“She’s not here,” Adagio grumbled. “Went shopping or something.”

Aria snickered. “So you’ve been stuck in that thing all day?”

Adagio clenched her thighs and the mess sagging between them squished. She winced. “Y-Yeah.”

Even though her nose wrinkled with each step, Aria strolled around the counter to inspect the damage. Adagio wanted to step away, but couldn’t work up the nerve. She’d come across as vulnerable no matter what she did.

When she saw the brown, lumpy padding, Aria whistled lowly “Wow, you destroyed that thing.”

Adagio’s ears burned. “Shut up.”

“Phew!” Aria waved her had to ward off the stink. “That’s worse than the load you dropped during that test.”

Adagio slammed the counter top. A sudden, embarrassed rage boiled in her gut. “I told you not to bring that up or—”

Aria shoved her knee into the seat of Adagio’s diaper. Poop shifted and pressed deeper against her, freezing out her anger. “Or what?”

Adagio couldn’t speak as her blush spread from ear to ear. Aria crossed her arms with a defiant smirk. She was reveling in this victory.

Her knee slipped away from Adagio’s diaper, leaving the messy padding to settle back into place. Adagio couldn’t believe it. Where was this newfound smugness coming from? She never had this much trouble keeping Aria in line before.

Stupid diaper. She grumbled in her head. Her authority wouldn’t be challenged if she was in control of her bowels. Aria was only getting a big head because her padding was clean.

“Whatever,” Adagio grumbled as Aria walked back around, fingers pinching her nose.

“Just don’t ask me to change you,” Aria quipped.

“Wasn’t gonna,” Adagio said through clenched teeth. Sonata had taken the diapers anyway. Even if Adagio did lower herself enough to beg for one, it wouldn’t matter.

“Sure you weren’t.” Aria smirked. A vein on Adagio’s forehead bulged. Just who did she think she was?

Adagio wanted to snap at her. If only the shoe was on the other foot, then they wouldn’t be having this problem.

I am going to give her hell when I catch her using that thing. Adagio reluctantly returned to her cereal, but frustration had replaced her appetite.

The two went silent now that the mocking session had passed. Adagio wanted to bicker more, unable to stand the fact that she hadn’t come out on top, but couldn’t muster up the nerve. Anything she said wouldn’t have any effect thanks to the mess sagging between her legs.

So she simmered in her own stinky loss while Aria toasted a bagel.

She didn’t bother finishing her second round of cereal. She wasn’t hungry anymore.

Dumping it in the sink for someone else to take care of later, Adagio waddled around the kitchen aimlessly. Her diaper squished and smushed with each step, and she honestly couldn’t decide if that was grosser than just standing still in it. But Aria’s snickering didn’t help.

Laugh while you can. Adagio growled internally. Who cared what Aria thought anyway. Adagio would get the last laugh if—when—she put together those shattered gem pieces.

Best not to mention that, she decided. It’ll be better as a surprise.

Oh yes it would. Just think, her as the only Siren able to feed off negativity again. Wouldn’t that just drive Aria crazy. The thought actually brought a devilish grin to her face.

“What, are you enjoying yourself now?” Aria cracked from behind her bagel.

The smile dropped. Adagio scowled at her, retort on the tip of her tongue. But just before she could voice it.

SLAM!

“I’m baaaaaaack!” Sonata’s clear as day voice rang out from the front door. Adagio flinched. Aria smirked.

They both stood still as Sonata made her way into the kitchen. The rustling of plastic announced her arrival. At first Adagio thought it was the sound of her diaper, but when Sonata appeared she knew better. It was her shopping bags.

Two fistfuls of bags, looking like wrecking balls at Sonata’s sides, thundered their way into the kitchen. Adagio could make out bags of diapers, rash cream, baby powder, and a whole host of other stuff that she didn’t even know what to call. Her gut sank, especially as she saw the big, stupid grin on Sonata’s face.

The youngest Siren sniffed the air, and her nose wrinkled. “Ooof. Did someone go potty while I was out?”

Aria point. Adagio covered her diaper with her hands. The brown lumps were too big to hide though.

“Oh wow.” Sonata dropped half the bags and waved her hand in front of her nose. “That’s a doozy, Dagi.”

“Can it!” she growled through gritted teeth. “And who told you you could go shopping?”

Sonata frowned. “But we… we needed baby powder. And while I was out I found soooo many things I thought we could use. For example…” she dug a hand into one of the bags, producing a large, magenta training potty. “Ta-da!”

Aria and Adagio glared at her.

Sonata shook the potty. “Ta-da!” she tried again, more nervous. “Oh come on girls, this will be so helpful. We can use it to practice our potty training.”

“We already have real potties for that,” Adagio growled. She blushed and shook her head. “I mean toilets! Look, forget all that crap, okay? We won’t even need the diapers for much longer, let alone all that other garbage.”

Sonata cocked her head, eyes on the dirty diaper around Adagio. “Are you sure, because that it looks like you definitely need—”

“Watch it,” she snapped.

“But it’s true!” Sonata reached back into the bag, withdrawing a bottle of baby powder. “And this isn’t garbage. We need it to keep us from getting diaper rashes.”

Aria cackled, eyes on Adagio’s browned bottom. “Might be a little late for that.”

Sonata’s attention turned to the snickering girl, eyes lighting up. “Oh, and I got something just for you, Aria!”

“What?” Aria’s eyes narrowed.

Sonata dropped the rest of the bags on the floor and rooted through them. “Aha!” She pulled something free.

It looked like plastic bloomers. They were tinted purple, but were still see-through. There was a zipper in the back meant to keep them nice and tight, and even a padlock of all things at the waist.

“What the hell is that supposed to be?” Aria seethed. Adagio couldn’t help but smile deviously.

“They’re plastic pants,” Sonata declared, blissfully ignorant to the mounting anger in the room. “So you don’t lose your diapers again.”

Adagio cocked an eyebrow at Aria. “You lost them?”

Aria’s face was pink. “I took them off last night because I don’t need them, okay? Sue me.”

Sonata’s brow furrowed. “But, didn’t you pee yourself in the hallway? I could’ve sworn I had to scrub it down last night.”

“Did you now?” Adagio put her hands on her hips, smirking as Aria squirmed. Oh how quickly the tables turn.

“Yeah,” Sonata said very matter-of-factly

“No!” Aria insisted. “Well, yeah… But I don’t need those things!”

“Aww, come on!” Sonata jiggled the padlock and held up a key in her other hand. “See, they even lock to make sure your diapee never comes off by accident.”

Forget pink, Aria’s face was red. “I am not wearing that!” she screamed. “And it didn’t even come off by accident anyway!”

That cocked on of Adagio’s eyebrows. She strutted toward Aria, her smirk growing. “So you took your diaper off on purpose only to cover the hallway in urine? Am I hearing that right?”

Aria’s face dropped. She tried to retort, but the words caught in her throat. For a moment, she just stood there, gaping like a fish out of water.

Adagio nodded to Sonata. “Get those pants ready.”

“No!” Aria shouted. She backed up, only to bump into the kitchen table. She immediately turned to flee as Sonata encroached.

“Oh no you don’t.” Adagio crossed to her, ignoring the squishy sensation between her legs. The second Aria’s back was turned, Adagio grabbed her.

“Let go of me!” Aria thrashed as Adagio hooked her fellow Dazzling in an awkward full nelson. Her arms struggled, but were reduced to too short a range to make any difference.

Sonata was still approaching, unzipping the plastic pants as she eyed Aria’s diaper. “Don’t worry, you’ll love them! I tried them on at the store and got so jealous of you.”

Her cute attempts to placate her friend did not go over well.

“Don’t come near me!” Aria screamed. She kicked furiously, still trying to break free of Adagio’s grip. “I’m serious, Sonata, stop!”

“Keep going!” Adagio commanded. She was not going to lose this one. Aria had to learn her place.

Sonata obeyed. Probably because she was excited to doll up Aria a little, and not because she was actually paying attention to her orders. But it didn’t matter, so long as she did what Adagio said.

Now Aria’s kicking actually worked against her. When she brought up a leg to fling at Sonata, the plastic pants were able to slip right up it.

“H-Hey!” Even from behind, Adagio could tell Aria was blushing up a storm. She tried to shake the pants off, causing her diaper to crinkle like made. But Sonata held firm, even giggling at the attempt, which did wonders for Aria’s blush. “Stop it already!”

Adagio snickered. “No need to throw a temper tantrum, Aria,” she teased.

Aria stamped her foot in anger. “I am not throwing a temper tantrum.”

It was almost too perfect; Adagio could barely hold back her laughter. “Keep acting like a big baby and we might just have to treat you like one.”

“Ooh, can we?” Sonata eagerly chipped it, forcing Aria’s other leg through the remaining pant hole. “That sounds so fun!”

“Don’t you dare!” Aria hissed.

“Awww.” A disappointed Sonata still pulled the plastic pants up and over Aria’s pampers.

Aria didn’t stop struggling as they were zipped up, but she couldn’t break free from Adagio’s hold. Nearly trapped, she looked back at Adagio in desperation.

“Don’t,” she begged, biting her lip. “I won’t take them off anymore, I swear.”

Adagio just grinned. She’d won. Her authority wasn’t going to be questioned anymore, no matter how full her diapers got from here on out.

“I know you won’t,” she whispered into Aria’s ear.

She released her from the full nelson. But before Aria could get used to having her arms back, Adagio struck the final blow. She bent down, and snapped the little padlock on the back of the pants in place.

click.

Aria was locked in.

Pushing away from her, Aria stumbled as her fingers dove for the lock. “No no no!”

“D’aaw!” Sonata’s fingers curled as she covered her squee. “You look so cute, Aria!”

“Do not!” The blushing Siren screeched. Her face was going to burst into flames any second now. She dug her fingers into the plastic pants, but they wouldn’t tear. She fiddled with the lock, but it wouldn’t budge. She pushed the pants down, but they remained snug at her waist. “Get these off of me!”

Adagio snatched the pants’ key from Sonata. Dangling it in front of Aria, she let the cruel taunt sink in. “Oh, we will. If you need a change, that is.”

Aria opened her mouth to reply, but was unable to speak. Her face shifted from red embarrassment, to pale shock. “You wouldn’t,” she finally managed.

“Yes I would.” Adagio clenched the key in her fist, while an out-of-the-loop Sonata just looked between them with confusion. “That diaper only comes off when I say it comes off, Aria. You’d do well to remember that.”

“Buh— Wha— I— You—” Aria sputtered, unable to send back a fireball of a retort. She was trapped, and they both knew it. Questioning Adagio’s authority was off the table.

With a shrill shriek of defeat, Aria stormed off. Her face was red again, be it from anger or humiliation, Adagio couldn’t say. She just watched her scramble up the stairs with an amused smirk. Aria was probably going to try and throw some clothes over her shame, but it wouldn’t change anything.

Adagio looked down at the key in her hand, her smile only growing wider. She’d won, and it felt great.

“Do you think we were too hard on her?” Sonata asked, frowning. “She looked a little mad.”

“She’ll get over it.” Adagio waved off. She started to breath a sigh of relief, but a sickening stench slapped her nose back to reality. Adagio looked down, remembering her nighttime accident was still plaguing her.

The sensation of the sticky, cold mess against her butt and inner thighs was back in her head. The temporary reprieve she’d gotten from putting Aria in her place was over, and now she couldn’t ignore the awful, stinky mess between her legs. It really soiled her victory, in more ways than one.

Sonata seemed to notice too, as she waved her hand to waft the stink away from her nose. “Peeyew!” she cried. Eyeing Adagio’s diaper, she smiled innocently. “Wow, Dagi. Your diapee sure is sagging. Maybe we should get you your own plastic pants too!”

Adagio narrowed her eyes at the dimwit. One look that immediately forced Sonata to understand that was never going to happen.

“Just change me already,” she grumbled.
