[ABDL, Diaper Use, Mental Regression, Brainwashing]

It was supposed to be a simple task. Get Reaper Princess out of Blood Princess' clutches, lest she end up brainwashed by the woman's maternal nature and how quickly she could turn one into her baby. That's what it was supposed to be.

And yet here they were. Stuck inside a nursery underneath the school. Stuck inside a room that left them awfully vulnerable to that very same Blood Princess' love. All because they tried to act like they were sick. And if she found out that they weren't sick, then...

The two Princess Series girls, Beast Princess and Steel Princess, were in a predicament that was practically inescapable. Especially since Blood Princess had already made her move, closing the door to the nursery once she arrived. She was there to take care of them, even if neither of them truly wanted that kind of treatment.

"Beast Princess, what do we do..?" Steel Princess asked as she looked to her tanned ally. Surely they had a way out of here. Even if they didn't have their gear on them, they were still far stronger than any normal human. They could force their way past her, couldn't they?

Beast Princess narrowed her eyes a little. All while she felt her stomach trembling and growling as soon as she laid her eyes upon Mom- Blood Princess. "We... We just have to get out of here. That's all." She didn't know how to get out. She just knew that if they stayed here, they were going to end up brainwashed. And given Reaper Princess' state when they arrived, they didn't have much time before Mommy- Blood Princess would get through to them.

"Ara... What are you girls whispering about?" Blood Princess giggled softly as she let one hand rest up against her cheek. "You aren't thinking of anything naughty, are you? You're just going to get hurt if you try something naughty. Just listen to Mommy and let her handle everything, okay..?"

"L-Like hell we'll do that..." Beast Princess tried to sound tough, but her usual roaring protests were like mewls when she was faced with Mommy. She could barely even stand on her two feet. She just wanted to sit down and... relax...

Steel Princess was quick to notice Beast Princess' mind faltering, mostly due to how she swayed side to side. But Blood Princess hadn't done anything to her, at least not beyond talking to her. Was it the brainwashing that still lingered in her mind, or... or... What... What was she thinking of..?

The longer they looked at Mommy, the less they were able to think. Was she doing something to them? There's no way that they could tell, especially with their minds in this state. And yet she just kept on gently smiling towards them. All while slowly, carefully, stepping across the padded floor. All so she could get those girls into something nice and cozy. After all, she had helped dear Reaper Princess get nice and cozy as she started having that fever, so naturally she'd want to help the others as well...

"It's okaaay. It's okaaaaay..." Her voice practically swallowed all of their thoughts as it echoed through their minds. All while they felt a wave of warmth overwhelm them. "Mommy'll keep you all nice and healthy. Just relaaaaax..." It was hard to tell where she was coming from. All because of the pressure she exerted over their minds thanks to her love and care..

But Steel Princess just barely managed to break free as soon as Mommy laid her hands on her. "D-Don't... Touch me..." She muttered, panting as she tried to look through her glasses. But it was hard to do so, since they were completely fogged up. And even her normal vision wasn't great, all thanks to the fog inside her mind. "I don't... need..."

"Of course you need help, Steel Princess. Don't try and resist Mommy, you'll just get hurt all over again." Blood Princess smiled even though the girl tried to resist, all while gently taking a step back to wrap her arms around Beast Princess. "Just look at Beast Princess. She knows what it's like to listen to Mommy."

"Mommy..." Beast Princess muttered, even drooling a bit. All while ignorant of the bib that she wore, as well as the cute infantile dress, and the cute hood, and especially the big and thick lion-printed diaper that she wore around her waist. She didn't even notice that it was spreading her legs so far apart that she'd have to waddle. She was completely submerged in the blissful warmth of her Mommy's love.

"K-Kiki..." The sight of her fellow Princess having fallen this far was too much for Steel Princess, to the point where she had to use her real name. It was both a shocking sight, but also a comforting sight. Mommy was... Mommy was going to love her that much..? W-Wait, no, she shouldn't be focusing on that. She should be trying to get away.

And yet her legs didn't want to listen. She took a single step, and ended up tripping over herself when one of her feet just didn't move. Which prompted poor Steel Princess to end up with her face planted on the extra padded floor. It didn't hurt, though it did leave her a bit disoriented. Not the best combo considering what had already happened to her.

"There there. I told you that you'd get hurt if you resisted..." Blood Princess's soothing voice echoed out once more as she let go of Beast Princess, though not before carefully letting her lay down on her side. She was such an adorable girl like this... Ahhh... No, it was awful for her to wish that the girls got hurt so she could spoil them. She was there to protect them and nurse them back to health, not permanently baby them. Even if she really wanted to.

Steel Princess tried to get back up. But she just couldn't. Her limbs weren't responding. Her mind was getting foggier with every passing second. And the more she tried to resist, the more she ended up having her thoughts... drowned out... by... Mommy..?

Using what little ability she had to think all on her own, Steel Princess finally noticed the faintest sweet sound. It was like... A mostly muted nursery tune. And it seemed to get louder the more she thought. Only as she started to piece together what it meant, did she lose track of it. Much like she lost track of her thoughts, as a bit of drool poured out the side of her mouth.

"Oh dear, oh dear. You're leaking everywhere, Steel Princess. But don't worry. Mommy's here for you."

Steel Princess tried her best to blink and focus on what was going on. But she felt something wet between her thighs. Something warm and wet that made her want to just close her eyes and lay down on Mommy's lap. Even as Mommy... wiped it... away...

Ah. She had... She had wet herself. That was why Mommy was wiping it away. It was only as her fingers brushed against her soft body that she realized what had happened. "N-No, M-Mommy. I-I... I-It was just..."

Mommy didn't let her finish, merely putting a single finger across her lips. "It's okay. We all have accidents when we're sick. But don't worry. Mommy has the perfect diaper for you. It'll make sure you don't make any messies, and it'll make you feel so nice and cozy that you'll feel like you're dreaming." Her voice never raised an octave. She was always so smooth and kind. Why was she trying to fight back against Mommy when she was like this..?

Even the sight of the diaper, which had a cute cartoony print of Culverin Bear on the front and on the back, didn't embarrass her enough to snap her out of the haze. If anything, the idea of wearing a diaper that had her beloved Bear on it... It made her feel like he was there, comforting her and making sure that she enjoyed the experience.

Steel Princess didn't really try to struggle after that. Not as Mommy lifted up her legs to allow the diaper to slide underneath her butt. Not as Mommy cleaned away the last few droplets of pee that had poured out of her. And especially not as she felt the diaper getting secured around her waist. If anything, she started to slip deeper and deeper into Mommy's loving trance thanks to the diaper clinging to her in such a wonderful manner...

"Mmmm... W-What's... Oh. Oh nooo..."

And as she sank deeper, Beast Princess finally managed to snap out of her trance. If only enough to notice that she had been forcibly dressed like a baby. Was the diaper around her waist bigger than last time..? Yeah, yeah it was. She remembered the thickness of the last one perfectly, because she forced herself back to her room as soon as Blood Princess left her alone for a minute or two. The humiliation of letting that thing crinkle was nothing compared to the thickness of the one she wore right now.

It also wasn't anywhere near as bad as seeing Steel Princess end up just as brainwashed as her. But at the same time, Blood Princess was completely distracted now, wasn't she? That meant... That meant that she could get out of there. So what if she was diapered!? She'd make it back to the dorm and kill anybody that saw her!

"Sorry, Steel Princess! You're going to have to deal with Mommy!" Beast Princess cried out as she tried to make a break for the door. She just had to get away. Even if she had to waddle the whole damn way, god why did her diaper have to be so thick!? Why'd Mommy punish her like that!?

"Ara... You're being naughty, Beast Princess." Blood Princess giggled. And as soon as that voice echoed through Beast Princess' ears, the girl was unable to make it a step further. All because of the hold that the older Princess had on her. "Don't you want your nummies before you go? You really need to eat to grow big and strong so you can serve Lord Bossler to the best of your ability..."

Beast Princess felt sweat run down her face. Why wasn't she running!? She could make it to the door! It wasn't locked or anything, she just had to endure the humiliation of the crinkling diaper beneath her waist! And yet... And yet... T-The offer of nummies...

Slowly but surely, the humiliated Princess turned around to face Mommy. "I... I-I want nummies..." She muttered, all while waddling towards her. She couldn't resist. Mommy's words were too strong, and her care was even stronger. Especially as her tummy started rumbling, begging her to eat.

"That's a Good Girl. Mommy knew you wouldn't try and get yourself hurt." Mommy chimed, all while giving her sweet little Baby Princess a hug. A hug that slowly lowered her onto the soft padded floor, all while she gently hummed a sweet lullaby into her ear.

Beast Princess' eyes widened for a moment as she recognized the lullaby. It was the same lullaby that Mommy had sung to her when she was her baby last time around. It made her feel all sorts of fuzzy and happy inside. This was bad. If she kept on listening, she'd definitely... Definitely...

Drool poured down her chin as her gaze turned nice and absentminded. Mommy's lullaby was really nice... Ahh... She wanted nummies... Biiiig nummies... Big squishy nummies and then milkies from Mommy...

Mommy giggled, all while she carefully helped Steel Princess sit up as well. They were so adorable. Clad in their cute little onesies with their even cuter diapers around their waists. The cutest little lion, and the cutest little bear. They were definitely going to grow up and be some of the greatest Princesses that the organization had ever seen. But for the time being, they were her Baby Princesses, and as their Mommy she was going to make sure that they were kept well fed and well rested so they wouldn't get sick again.

"Say Aaaaaa..."

Both girls didn't notice how Mommy suddenly had a bottle full of baby food in her hands. Nor did they question it. They just opened their mouths and let their tongues stick out so the airplane could land, with each slowly swallowing the nice messy meal as Mommy took her sweet time feeding them. It was soooo delicious too. Why were they trying to avoid this kind of treatment? They should've just let it happen ages ago...

The more they ate, the more they started to gently rock back and forth on their butts. Their diapers were nice and cushy, the sheer thickness of them making sure of that, but these girls were still 'big girls'. So naturally, they wanted to avoid filling their diapies with poopy. Even though that was what babies like them were meant to do.

Mommy noticed the way that the girls tried to indicate that they needed to use the potty. And she just chuckled a little as she gave them each a kiss on the cheek. "It's okay. It's okay. Mommy's here. You can take her hand if you're afraid to go number 2 in your diapies. She'll be there for you..." Her words were so soothing and so comforting. So of course they didn't worry once she gave them the comfort that they needed.

Both Baby Princesses slowly closed their eyes and just... Let go. They just let everything that needed to flow out of them pass through without a problem. Whether it was the poopy that needed to pour its way into the seat of their diapers, or the pee that just carefully hissed out from their crotches. It all just poured out without restraint. All because they just let go and accepted that Mommy was right, and that they should listen to Mommy and not worry about a thing.

To say that they went number 2 was an understatement. It seemed like both girls had really been keeping it all in, no doubt due to the fact that they had been fighting a lot. So the back of their diapers very quickly started to expand outward, popping open their outfits and letting the extra brown side of their padding stick out. Such stinky seats, and yet such comfortable and happy girls. It didn't even matter that they were stinky, because they couldn't smell it. The delicious taste of Mommy's baby food had practically clogged up their nostrils.

With both Baby Princesses having messed themselves to the point where they both looked absolutely exhausted, no doubt due to the fact that they really needed to go potty, Blood Princess couldn't help herself as she pulled them both a little closer. All while moving her clothes out of the way ever slightly...

Just so the two of them could latch onto her nipples. Those nipples that were meant for babies and babies alone, so she could nurture them and help them grow nice and big. And since both Baby Princesses definitely needed to grow nice and strong after sinking into her care... Yeah, they definitely needed to have a little drink from her...

"That's it..." Mommy whispered as both Beast and Steel Princess suckled on her nipples through nothing but their regressed instincts. All while she gently ran her hands through their air. Combing her fingers through the strands as she watched over them. Ah... This was what gave her life meaning. Caring for those young girls that still had so much room to grow. All so they could eventually thank her in the future. Because they'd realize just how much this care meant for them. They'd realize, and they'd carry on her lessons to their children. And their children could end up in her care as well, so she could tell them all sorts of stories about how their mommies had ended up being adorable babies...

Blood Princess giggled softly as she let her maternal mind wander. All while both girls slowly but surely latched off her nipples and gently laid their heads down on her lap. Snoring and snoozing away, as the warmth had completely consumed them and forced them to rest. All so they could get the sleep that they needed, the sleep that Mommy desperately wanted them to go through.

When they'd wake up, they'd be as fresh as babes... And they'd be stronger than ever, all thanks to Mommy's care...

"Hey, Steel Princess. Is it just me, or do you feel like something's off too?"

"No, I don't think so. But I don't think I've had such nice sleep in ages..."

"That's right, I slept like a rock last night. I could go for a fight against Gelato 5 right now, I'd take them all out all on my own!"

"Oh, Beast Princess... But you're not wrong. With my darling by my side, we could destroy them again and again, all in such short time..."

Both girls felt extremely well rested. And yet all of the common Gekko soldiers were strangely quiet and jittery as they walked past them. How strange. Were they forgetting something? Nah, they must just be awed by their strength. Of course they were. They were grunts, and they were Princesses. It's just part of the natural order.

"Beast Princess! Steel Princess!"

But one person always treated them like a pair of gal pals. Reaper Princess. Who looked just as radiant as they did, if not more so. Had she also slept like a rock and gotten all the rest she needed?

"Eh? Why are you two wearing diapers?"

The coin dropped as soon as Reaper Princess pointed out the obvious. With both Steel Princess and Beast Princess looking down to notice the extra thick double-layered diapers that they were still wearing. And thus, the humiliation returned, as they both let out screams that pierced all the way to Gelato 5's base..

All while Mommy softly giggled within her room, hoping that she could take care of the Princesses again. If she could, then she'd definitely make sure that they knew how much she loved them...
