[ABDL, DDLG, Soiling, Futanari]

The Phantom Thieves of Hearts. Those that had managed to change the hearts of many that stood against humanity and tried to take advantage of their apathy and their need to feel comfortable without putting up a fight. They had succeeded in doing so, freeing the world from the Conspiracy that had been pulled over it.

...But that didn’t mean that they were done. Or rather, it meant that the Leader’s true desire could be let free. He didn’t just worm his way into the hearts of several girls just to lead them and turn them into thieves that followed his beck and call. No, he had something else in mind for them. Something that could best be described as… Infantile.

It started out slow. Carefully sneaking into the Metaverse while it still existed. Sneaking into the hearts of his allies. And then changing their needs and wants by placing strategic little gifts. Bit by bit, they became more and more dependent, until they asked if they could take the next step.

From that day onward, they disappeared from the public eye. They didn’t need to show themselves off to anybody except for him. And instead, they arrived in the home that they’d spend the rest of their lives in. The nursery that belonged to them and only them…

The five girls that had helped Joker free the hearts of man had been stolen away. And now, they were his greatest treasure. A treasure that he made sure to spoil day in and day out, making sure that they were cared for and taken care of.

And today would be just another day of that loving routine…

“I’m home.”

Joker, the black-haired boy that had led the thieves to victory, walked into the pastel-colored nursery. An area of his personal Palace that he had specifically designed so that it was ready to house anybody that might need to rest there. Including the five girls that had been there with him.

Each of them had abandoned their adult identities. They didn’t need them any longer. Nor did they need their names, because they were Daddy’s little girls, after all. And what Daddy said, was what they responded to.

Panther. Queen. Oracle. Noir. Violet. Five girls that were at the peak of their physical ability due to all of their training, now… Little more than adorable babies, after having given up everything to their Daddy. And it was evident by the way that they were dressed.

Just looking at one of them, such as Panther, was enough. While she still wore the colors of her original disguise, it did little hide her identity at this point. Her mask was gone, turned into a bib around her neck. Her body was left mostly uncovered, with only her shoulders, her legs and her hands being covered up by adorable latex accessories. And of course, the thing that characterized every single baby in this nursery.

A thick, shiny and crinkly diaper. Perfect for them to wear. Perfect for everything that Daddy wanted to do with them. After all, he protected them. It was only right that they wore diapers that showed how dependent they were.

Every single girl was dressed in the same fashion, with the slightest of tweaks. Beyond their masks being displayed on their cute bibs, the colors of their accessories and their diapers matched that of their original disguises, helping set them apart. They were babies, they didn’t need anything more complex than that.

“Daddy…” Violet, the newest of the five Phantom Babies, mumbled a little as drool ran down her chin. Her hand was between her thighs, pushing up against the crotch of her diaper. Thanks to how intimate she had gotten with Daddy, she was always in quite the horny state. And she always wanted him to get closer to her so the two could ‘play adults’. Something that he was happy to do, in between changes.

However, today was not one of those days. Despite her expression seeming like she wanted to have the usual kind of fun, the pained look in her eyes made it clear that something was different. And she wasn’t the only one, as Panther crawled closer to their masked Daddy with a needy look in her eyes.

“What’s the matter?” He asked, slowly kneeling down to look at two of his dearest babies, pulling the pacifier out of his blonde baby’s mouth so she could speak. She loved sucking on that thing, as it kept her lips busy, but it made talking rather difficult.

The red-clad baby squirmed a little as her stomach started rumbling. It wasn’t because she was hungry, the flow of time within the Metaverse meant that they wouldn’t experience many of the usual needs that humans had. “Daddy, tummy hurts!” She said, intentionally simplifying her vocabulary because it was what Daddy liked to hear. Even if she sounded like a little brat when she did so.

“Mmmm? Your tummy?” Joker asked, as he put a hand on her naked belly. Slowly rubbing it, bringing a little bit of comfort to the blonde baby. “And what about you, Violet? Is your tummy hurting too?”

Violet nodded as she crawled over, shivering a little. “Poopy won’t come out…” The nervous baby muttered, her hand still grinding against her diaper. Even when she felt discomfort, she still wanted to masturbate. What a naughty baby. This was why he put them all in mittens…

“Another blockage? Did you two eat something you shouldn’t have?” He asked, and they both shook their heads. A cursory glance at the back of the nursery revealed the other three babies were in a similar condition, they just preferred to keep quiet about their issues. Only the shy and the loud baby were confident enough to ask for Daddy’s help.

Joker smiled. Of course he’d help his little babies take care of their business. That was what Daddy was meant for. Helping them out in their time of need. And so he rubbed away at their tummies, giving them all of the stimuli that they might need.

Both Panther and Violet started giggling as he rubbed away at their tummies. It was like getting tickled, which always made them pee. But their bladders weren’t the full ones, as the crinkling from their diapers didn’t intensify the more he rubbed. Just as the blonde Baby had said, the problem was entirely with their poopies.

Since he couldn’t stimulate their bowels with just a few rubs, he had to do something else to give the stimuli it needed. And that meant that he pushed his palms as hard as he could down on their tummies, almost as if he had punched them in the gut. Not as forcefully or as suddenly, so they wouldn’t be scared into sobbing the day away. But just enough that they might be able to get all of the poopy out of their bowels.

Both of his dear babies started to squirm even harder as they felt the pain run through their tummies, but it wasn’t enough. They could feel a little bit of it loosening, but it didn’t get close to what he needed. He had to go harder. He had to do much more to make them go poopy.

Joker pulled his hands away, sighing a little. He preferred to get this over with without using anything external, but it looked like his babies were really blocked. “Daddy’s going to have to give you the tummy juice, okay? The stuff that makes you make huge boombooms. Can you both handle it?”

“Mmhm! Lots and lots of boombooms!” Panther giggled. Just the idea of making a huge mess was enough to perk her up. In fact, it made a stiffy slowly grow inside her diaper. One of the few changes that Daddy had made to her, and Queen as well, to make them stand out amongst the other girls.

Violet slowly nodded. She was also quite fond of making huge messies for Daddy, but she wasn’t the most enthusiastic about announcing it. She much preferred to just sit there and push it all out until she got praised. And that praise would loosen everything else up. That was how she usually won the messing contests with the other babies.

“Alright. Daddy’s going to remove your diapers for a moment, then. Don’t kick, okay?” Joker said, as he slowly helped both of the girls onto the padded floor below, laying them down so it’d be easier to tear the tapes off their waists.

Both of the two babies remained as calm as they could, as the diapers came undone. The tapes were durable and reusable, so he didn’t have to go through a lot of effort to close them back up after giving them the ‘tummy juice’.

Opening their diapers up revealed their spotless pussies, and in the case of Panther, her adorable baby cock. The thing was quite the throbbing shaft, always ready to blow a load for Daddy.

Their puckered butts were adorable. And as clean as they could be. Which really did show how absolutely pent up they both were. It did make it a lot easier to guide a straw into the both of them, so that they could receive the enema that would clear up their jams…

But that wouldn’t be enough. Joker knew that from experience. A little flick of the wrist, and the mental space materialized a pair of bottles filled with chocolate milk. Five, actually, but he wanted to focus on these two first before he’d give the others their ‘tummy juice’.

“Drink up, Panther, Violet.” Daddy said, as he handed the two babies their bottles. Their mittens didn’t allow for the best grip, but using both hands at the same time meant that they could easily stuff the rubber nipple into their mouths, distracting them from the rush of water pouring into their butts.

Both of the cute babies drank and drank from the big bottles, slurping down as much of the chocolate milk. Unaware that the chocolate ingredient was actually a flavored laxative, designed to put even more pressure on their bowels than both the enema or the pushes that Daddy did ever could.

After their dear father figure finished pumping the ‘tummy juice’ into their bowels, he pulled the small straws out of their holes, and quickly taped them back up. To ensure that they wouldn’t leak, because the combination of the juice and the milk would cause quite the messy display.

They were both ready to make a mess. He had made sure of it. But just to be extra careful, he put his hands on both of their crotches, rubbing away through the thick and crinkly padding. Just to give them a little extra push.

For Panther, it was divine. She could feel Daddy’s hand brushing up against her cock, making her squirt plenty of that sticky goodness straight into the padding. She was a sensitive girl, and this was hardly the quickest shot she had ever made. But it was definitely a show of just how easy it was to make her cum.

Violet, on the other hand, just squirmed silently as she swallowed more of that nice chocolate milk as Daddy practically fingered her through the pamper. It felt really good. It felt like heaven. This was exactly the kind of love that she wanted from him. Though he didn’t stick his hand down her diaper like he usually did, this was still fun…

And this stimulus was enough to make everything come crashing down on them at the same time. Their horny feelings, plus the laxative in their tummies, plus the enema, all melded together to make sure that their tummies wouldn’t be hurting anymore. Their poopies were going to be loosened, and they were going to fill the seat of their diapers with such a huge mess that one could hardly call them human…

Panther’s shock at her tummy growling and moving all about was so big that she dropped her bottle, the thing falling straight out of her mouth as she happily declared what she was about to. “Panther making boomboom!” She cried out as she bit into her lower lip, pushing and pushing as her crinkly diaper started making all sorts of loud sounds. She was doing her very best for her Daddy, to get rid of all the stinkies that were stuck inside her.

Violet was shocked, but the feeling of the chocolate milk was enough to keep her calm, as the suckling sounds echoed around her. She didn’t move an inch as her legs spread apart on their own, the seat of her diaper filling up bit by bit. She was pushing out so much that it was hard for her fellow baby to keep up…

Joker smiled as he watched the seats of their pampers slowly inflate due to everything that was being packed into them. It was astonishing. But it was exactly what he had come to expect from the two. It was something that he loved about them. The sheer capacity that they both had. The amount that they could just push out without a care in the world…

Panther let out more and more moans, something that only grew louder as Daddy moved his hand down from her dicklet to her mess, pushing it up against her and smothering her cock in the mess. It felt heavenly to have it all squishing around her. It made her make so many squirties, orgasm after orgasm piling on and on. She could hardly keep conscious with this much pleasure pouring through her, the delight filling her to the extreme…

Violet was just as filled with ecstasy. She just didn’t vocalize it, preferring to drink more and more of that chocolate milk to make her tummy happy. Which technically made it angrier, as more and more of her sloppy messes poured out. Her diaper was about twice the size of her blonde ‘sister’s at this point, and hers was already the size of a beanbag chair. A testament to just how much they both could pump out.

Joker loved seeing the two have so much fun, but he couldn’t keep himself to the two girls, as he let his hands come off their butts. “You two have fun with each other, okay? Daddy’s going to go help your sisters with their terrible tummies. Don’t make too much of a mess, okay?”

Neither baby could really respond due to their poopy-induced hazes. The red-clad baby was too busy making a total mess of her diaper thanks to all of it wrapping around her cock and milking it dry, and the black-clad baby was busy drinking the rest of her chocolate milk. It was a miracle that her diaper was able to hold it all inside, given how much she had filled it with.

But as Daddy went to go help his other Babies, Violet slowly let go of her bottle, putting it aside as she looked to Panther. The baby that was cumming her mind out.

A soft yet dominant smile worked its way onto the pooping redhead’s face as she wrapped her arms around her ‘sister’, kissing her straight on the lips as she pulled them together. And in the process, their diapers started to grind against one another. Giving them a little extra pleasure, while they both waited for their Daddy to come back.

This was what she did whenever Daddy wasn’t there. She took charge. And thus the ‘oldest’ Baby in the nursery became the ‘youngest’s bitch, the blonde Baby letting out more and more moans as she was forced to hump her diaper as she kept filling it.

Both of them would be at it for a long time. Long enough that Daddy would be able to watch them the entire time, after he finished dealing with the other three. And enjoy the sight he did, stroking himself off as he watched all of his Babies having fun.

All in all… Another normal day in the Phantom Nursery. Babies enjoying each other’s poopies, and Daddy spoiling them rotten. And the best part of it all?

They loved every moment of it. Both Daddy, and his babies… And who knows, maybe he’d add a few more to his nursery, should he get a little greedy...
