[ABDL]

"For the last time, Illustrious. You have to listen to me when I'm telling you this. I am not a baby."

A rather peculiar situation was brewing in the Royal Navy-dominated naval base. The young Destroyer Javelin, famous for one of her fatal accidents that had left her at a drastically shortened height, was calmly discussing something rather infantile with the dignified Carrier Illustrious. The latter of which was shaking her head at the younger girl's affirmed declarations.

"Javelin, sweetie. You know what the admiral ordered. To prevent any additional damage to your frame, you have to wear diapers and be treated with delicate care. By all accounts, you are like a baby to him, and I just want to make sure that you're comfortable with the role." The white-haired woman sighed as she spoke, the displeased destroyer not backing down in the slightest... which just served to emphasize the garment that she had been forced to wear.

With every little dejected squirm and sway, a crinkle from the thick padding between the little girl's leg rustled forth, causing her cheeks to turn a soft light-red shade. Despite the low energy she possessed as a result of her current gas-lighted state, she was still an adorable little girl. It frustrated her that Illustrious didn't take her seriously at all or that the Admiral had chosen THIS as the treatment she should endure while she was incontinent, but she had no place to properly argue against it. After all, she had been placed in diapers after she had experienced quite a few combat accidents, including ones during skirmishes.

"Haaah... Well, if you won't take me seriously, I'll just have to prove myself to the Admiral. I won't sink like that ever again, and I'll be out of this diaper before long. You can count on it." Javelin tried to work up a bit of her usual energy, tugging at the waistband of her Royal Navy diaper as she attempted to prove a point... only to stop trying with a dejected sigh. She couldn't pull it off, she couldn't even rip a tear into the tough waistband. The wings of the diaper didn't even give way. She was severely weakened... 

"Since when were disposable diapers this durable..?" Her exasperation with the situation was evident as she propped herself up against the older woman, playing a little with the tight-shut diaper in an attempt to find an opening to no avail. Despite all of that earnest struggling, she hadn't made any progress, and all it earned her was a hug from the taller Carrier. A hug she accepted with... no real reservations. It wasn't worth fighting against.

"Please try to understand, little Javelin. We only want the best for you." The blue-eyed carrier smiled and gently nuzzled her cheek against her younger companion, who just sighed. She didn't think that the older-looking ship girl was entirely honest, but she wasn't wrong either. 

"You win, Illustrious. Do what you want." The purple-haired destroyer limply hung in Illustrious' grasp as she tried to just forget about everything that was happening. Maybe if she did that, she'd wake up in tip-top condition. Maybe she'd wake up and realize this had been some strange nightmare. That'd be nice.

Illustrious' smile grew a little pensive as the defeated tone of Javelin's words weren't the most reassuring, before it widened once more. She knew exactly what would cheer her up, if she grew used to it anyway. She needed to learn what the best parts of being a baby really were... and so she whisked her way to a secret little room that only her and a few certain others, like the Admiral, knew about.

As they made it into the naval base's most hidden secret room, Javelin felt something in her stomach. A gut feeling that told the saddened Destroyer that she should be worried. She dismissed the feeling, knowing that she couldn't do anything about it anyway.

The moment she saw the decor, the feeling in her gut was validated. Everything was either pink, cream, baby blue or baby pink, and pastel shades of each as well. She had been whisked away into a nursery for babies... One of which she absolutely wasn't. She was still a useful Destroyer, no matter what Illustrious said. At least, she would've been if she could work up the energy to pull that damned diaper off...

"Welcome to my little pet project, Javelin. Isn't it pretty? A nursery for all the littles that the Admiral have deemed unfit for general use, so that I can ensure they can be rehabilitated for the roles that he gives you. It's not the most extravagant place, but I'm sure you'll grow to enjoy your time here." Illustrious was more than happy to explain and explain, but that didn't make her little companion any more excited. It actually seemed to make her more peeved at her predicament.

"Yeah yeah. You're the Admiral's little darling, making us all into diaper-wearing 'babies'. You're enjoying this a lot, I know that, but I'm not. Just quit it and let me down." Javelin wasn't in the mood for what the older woman was selling, not a bit. It just fed into that feeling of inadequacy and the feeling of her independence being taken away from her. She didn't want any of this...

Illustrious shrugged her shoulders. "As you wish." The gentle-eyed woman relented and let the purple-haired girl gently fall the ground, the crinkle from the diaper hitting the floor all too audible to the two of them. The Carrier's gentle and pleased smile at the noise was directly opposed by the Destroyer's frumpy frown.

"So, I'm going to stay in here permanently, is that what you're playing at? What's going to stop me from running away?" Javelin asked as she started to roll onto her back, looking up at the ceiling that depicted a bright blue summer sky, something that she yearned to see in reality. It had been so long since she had been allowed out on a normal sortie, she just wanted to feel the sea breeze...

"I wouldn't quite call it a permanent stay, more... Well, maybe it's better if I just let you experience it all." The white-haired woman chimed as she skipped over to a closet that seemed to be stuffed full of different outfits for babies, demonstrated as she tossed several embarrassing pieces of clothing onto the floor as she dug into the very depths... Until...

"Ah, there we are!" Right as those happy words left her mouth, Illustrious pulled out a onesie that seemed to be sized for destroyers like Javelin. It wasn't the most humiliating outfit, but that didn't make it too exciting either. Plain-blue all over, plus a pair of mittens and booties to make sure she wasn't going to do anything on her own... It did make Javelin feel a little disgusted, but it was ultimately harmless.

Sighing in defeat, the purple-haired girl didn't even move a muscle as Illustrious gently slipped the outfit onto her, stuffing her arms into the 'sleeves' of the outfit so that the hands ended up inside the mittens. The legs were a little more difficult as she was still quite the padded girl, but with a little tugging, the Carrier managed to pull the Destroyer's legs into the holes, where the feet snugly slid right into the booties below.

As Illustrious zipped up the onesie, she made sure to flip the little girl's hoodie on, causing her to blush as she started to let the softness of the outfit soak in. It... wasn't actually that bad. Sure, she looked like a baby now, but it was nice and soft on the inside. She couldn't complain that much.

Except for the ass-flap. With how big her diaper was, that thing was one bad mess from popping off prematurely. It didn't help that the flap was decorated with a cutesy and cartoonish anchor.

Right as Javelin was (regrettably, given the blush that was growing on her cheeks) getting comfortable with her new outfit, her stomach started to rumble. She didn't even bother speaking up as she knew exactly what Illustrious was going to do. If there was one thing she knew about how babies were treated, it's that they were directly fed by their caretaker.

Sure enough, the white-haired woman giggled as she pulled out a little jar full of some kind of mushy substance. "Do you want the high chair, or do you just want me to spoon-feed you directly on the floor?" For once, the Carrier had given the infantilized girl a little choice.

"I-" Javelin's eyes lit up just for a moment as she savored the autonomy, before she realized how pointless it was. Her energy drained in a second as she sighed. "Just on the floor. It's fine." The onesie-clad girl muttered in reply.

The fact she immediately received a spoonful of the gunk surprised her. It also surprised her that Illustrious practically shoved the spoon into her mouth, causing her to cough a little as she swallowed the fruity mash. "G-Geez, and you're su..." The purple-haired girl was just about to complain about how rough that was, only to be distracted by how sincerely delicious the mash was.

"Can I have another?" She asked, almost sounding as excited as she once was.

"I don't know, little Javelin. Can you?" Her Carrieretaker giggled as she winked down at the babified girl, who immediately realized her mistake and began to bashfully blush more than ever.

"...May I have another spoonful?" She asked again, this time being a polite little child... which earned her the food that she wanted. Then just a few more spoons full of that delicious mush as she finished chewing through the first spoonful. She had earned a reward, and quite the hefty one at that.

So hefty that she had to let out a little belch to indicate that she had been stuffed full, the red on her face growing deeper. "Thanks..." Javelin was starting to come around, something that made her older companion giggle.

"Well, would you like anything else, little Javelin?" Illustrious was happy to accommodate any infantile needs the little girl might have, as long as she kept acting like the baby she was trying to condition her into being.

"...I'm kind of thirsty." The baby Destroyer replied as she looked straight towards the busty carrier's bosom. She was being awfully direct, just like an infant should be.

Illustrious could only smile and sit down, putting the food down by her thigh before caressing the little girl's head. She softly pulled the onesie-clad girl onto her lap, and pulled down her dress to expose her nipples. One of those large areola slipped into the Destroyer's lips, before she was allowed to gingerly suckle away. She deserved a nice nutritious drink for how nice she was acting.

Milk sloshed around in Javelin's mouth as she gently suckled from the older woman's teat. It was... kind of thin, actually. Sure, they weren't real people as they were nothing more than the spirits of the ships that had sailed the sea, but something within her told her that mother's milk was supposed to be thicker than this. It didn't bother her too much, if anything it actually made her suckle Illustrious' tit that much more vigorously. She wanted and needed that milk.

As the milk dribbled down her throat, she felt the white-haired would-be Mommy slowly running her hand through her hair. It felt kind of nice, as much as Javelin didn't want to admit it, but she was more interested in the delicious milk than she was a show of affection. She rolled her eyes and continued to suckle with an audible "nuk nuk nuk nuk" sound echoing throughout the otherwise lonesome Nursery.

"My my, you've turned quite eager, little Javelin. Although, I am very glad that you're wearing that diaper of yours... because right about now, you might just need it." Those words immediately triggered something within the purple-haired Destroyer, her eyes widening in fear as she realized just what the woman had done to her.

Javelin would've at the very least called the Carrier bad names for this turn of events, if not for the nipple still in her mouth. She couldn't cut off the flow of pleasant milk that was pouring into her mouth as her stomach started to throw a tantrum. It hurt a lot, but that wasn't the worst part of it. The worst was the gas that was being pushed out of her other end, causing the young girl to groan the best she could. Her pained noises were muffled by the nipple, but the defiant expression revealed it all to Illustrious.

"Oh my, you're turning into a little farty baby, Javelin. You must've gotten so full from eating all that mushy food... Here, why don't I help you get rid of all of that pressure in your tummy?" The blue-eyed woman’s foreboding words were not helping in the slightest, and neither was the way she wrapped an arm around Javelin's back to press her closer towards her.

Illustrious' hand slowly dug into the poor girl's back, pressing in just the right manner to make the build up in her tummy figure out what way it had to get out of her. Namely, the bottom exit. Before the Destroyer had a moment to even utter a word to try and protest this, stop her from ruining her credibility as an adult...

It just happened. A large torrent of muddy sludge just squeezed itself out of her poor hole. The back of her diaper immediately turned soggy and saggy from the way it filled up with a mixture of the Destroyer's already incontinence-induced poopies, as well as the laxative-laced oatmeal that 'Mommy' Illustrious had spoon-fed her. She knew that she shouldn't have given her the chance to treat her like a child... and yet...

Why did it feel so good?

Javelin couldn't quite wrap her little mind around it, but something about just letting loose and pushing all of that mush out, all of that horrid-smelling slurry of shit pumping into the seat of her diaper, quickly causing the buttons of her onesie's flap to pop off and reveal the padding underneath... It felt really good.

She didn't want to make it seem like she was enjoying it as much as she did, so she tried to calm herself down by suckling more of Illustrious' milk... but that just made her stomach more upset, which just made her poop her pampers more, and the cycle just continued.

Eventually, she both couldn't poo herself any longer, having thoroughly exhausted her colon's contents, but she also couldn't stomach even a drop more of milk. She pulled herself off Illustrious' nipple and immediately let out a satisfied and surprisingly subtly cute burp, before she collapsed against that massive bosom of hers. The plain-blue onesie-clad girl sighed in satisfaction, her cheeks still nice and red with embarrassed enjoyment.

Illustrious had not said a single word during all of this, but she seemed very pleased with this turn of events. It seemed like Javelin had learned the true value of being a baby, and it would leave an imprint on her psyche for many weeks to come. And, she didn't eve-

The little girl suddenly started to sniff against the woman's breasts, before she pulled herself out of her milk-and-poopy induced stupor as she glared up at her 'caretaker'. "That... is not the scent of my diaper." She was a clever little girl it seemed, already having put two and two together. Especially as she prodded her fingers against the 'thing' that pushed out against the Carrier's incredibly delicate dress. It stood out like a sore thumb...

The look on Javelin's face when Illustrious hiked her dress up to reveal her equally messy and equally adorable Royal Navy diaper? It perfectly reflected the bashful embarrassed red that now coated the white-haired woman's face. The mommy was just as much of a baby as her 'baby'...

And Javelin wasn't going to forget that any time soon.
