My Hero Regressademia: Nefarious Nursery?! Redux (Patreon)

I

Being a Class 3-A senior had lots of bonuses, one of them being the tons of practical experience that came with helping real, ranked heroes. Ochaco Uraraka and Tsuyu Asui had all that and intense and unexpected experiences from dealing with the League of Villains and the Paranormal Liberation Front. Over the years they were now practically heroes in their own right.

The pair had spent their high school years proving their worth in class 3-A, hoping to show that they belonged with the elite group of students there. When one of their instructors—The 18+ Only Hero, Midnight—asked them to assist her with a search and rescue operation, they jumped at the chance to help.

It was strange the way the female students of UA had started to disappear, with the first being Yui Kodai from class 3-B, who never returned to the dorms after a meal out and what she called a 'quick errand.'

After that, more and more students continued to disappear until class 3-B was completely left without female students. Search operations began promptly, but no clues were found. Even worse it kept happening until eventually all of class 3-A’s female students besides Ochaco and Tsuyu were nowhere to be found too.

Now both the staff of UA and the city were in full-blown panic mode, searching high and low for the missing women. Meanwhile, the rest of class 3-A had split off with various pro heroes to go look. Midnight started to brief Uravity and Froppy on what little information they knew.

“We're not currently sure why or how students are disappearing in broad daylight, but we do know the general area in which they’ve all gone missing.” She said.

In a display that seemed more ridiculous than helpful, she used the flogger she usually carried to point to a specific area on the map, the markings denoted it to be an industrial district somewhere on the outskirts of Mustafa. “We’ll look here,” Midnight stated, “this cluster of 20 or so buildings could easily hide that many people.”

The pair nodded to their instructor, determined to help their missing classmates and friends. Unfortunately, searching their assigned section of the city started off slowly. The trio worked diligently, traveling from warehouse to warehouse, talking to workers, and investigating each building. Still, they found themselves coming up empty-handed.

Undeterred, Midnight strode confidently forward, remaining determined that this was where the missing heroines would be found despite their current failures. Every warehouse worker they came in contact with seemed nervous about speaking with her. Despite her well-known status as a pro-hero, they still weren't quite sure where to put their eyes.

Not only was she rather curvaceous, but the skin-tight bodysuit she wore along with the black leathered breastless leotard made her appear like some sort of fetish exhibitionist to the unfocused eye. This didn’t bother her though as she walked confidently in her thigh-high stockings and knee-high leather boots, continuing on without paying the gawking stares and shifting eyes any mind.

Midnight’s long black hair fluttered as she lifted her red-rimmed glasses to rub her tired eyes a little. Tsuyu and Ochaco had both gotten used to their teacher’s hero outfit, as well as the strange looks it garnered from people around them. They were even secretly glad about the attention she attracted because with her around nobody bothered scrutinizing either of them. Their attention was fully focused on the main attraction.

Ochaco’s hero suit was also form-fitting, showing off more of her slightly above-average bust and toned body than she would have liked. This was due to an error caused by her request not being specific enough during the design phase, and now she was stuck with it. She had a large bright pink belt with darker pink accents that matched two armbands and a collar around her neck.

These served to hit pressure points on her body so her quirk would not make her nearly as nauseous as it normally did. Ochaco’s wide pink boots came up to about knee height and were built specifically for impact shock absorption should she come down from a height using her anti-gravity powers.

In stark contrast, Tsuyu’s suit’s tightness was on purpose; her frog-based quirk worked best because of it. It’d been built to aid with her natural camouflaging abilities, making it so the material could blend in with the environment around her. Still, when not matching her camouflage, her suit remained a very froggy green with black accents if only to keep her theme. Her web-toed footwear hit the ground with a soft *plip-plat* as she scanned the surrounding area with the thermal setting of her goggles.

Her eyes caught a warehouse about a block down giving off more heat than the others around it. “Ms. Kayama.” She called, “I’ve got something strange here.” She wanted to rush and see what the clusters of body heat shifting inside the warehouse she’d focused on were, especially since they didn’t walk around like normal workers. Even odder were the two much larger figures walking among them. They were bigger than any normal human and were mainly why she thought something strange was going on. She stayed put though, waiting for her teammates. Tsuyu was no fool and wasn’t about to walk alone into an unknown building without backup.

Ochaco came to her first upon hearing her call, giving a simple “What’d you see Hon?” to her friend.

Midnight snapped away from the worker she was questioning to see her two helpers staring straight toward a warehouse. She gave a small sigh of relief at the possibility of finally finding some kind of lead. She’d been so insistent on her hunch that this is where all the missing heroines had ended up that it would have been almost degrading to go back without any success.

“What’s going on Froppy? Do you have something?” Midnight asked

Tsuyu nodded, now that her instructor was here she explained the situation to the two of them. “Ribbit~ There’s obvious heat signatures in that warehouse. More than just the normal workers. Plus, two of them are larger than everybody else. Rib~ I’m not sure if they’re villains or not but it would be worth approaching with caution.”

Midnight nodded with agreement, and the trio approached the warehouse slowly. The huge front shutters were closed tight on the large exterior of the metal building but next to them, a regular-sized door stood completely unlocked and even slightly ajar.

“If that’s not an invitation to enter I don’t know what is.” Midnight thought.

No sounds came from within the steel structure. Cautiously Ochaco stepped forward first, pushing open the door while her allies covered her.

All three expected an enemy of some sort to present themselves, but instead, they were greeted with another building inside the metal structure. It'd been built within the confines of the warehouse they just entered, seemingly as a way to hide it from the public eye.

Rather than the boxes, shelves, and wandering workers they’d seen at every other warehouse in the area, they had stumbled across a large bright yellow concrete wall. Built into the front of it were two glass double doors. Hanging above them was a sign that read "Nefarious Nursery" in colorful neon backlit letters. In smaller print below were the words, “A place for Little Heroes who get too big for their britches!”

All three of them gawked at the structure.

Obviously, this was some kind of themed villain hideout, but it was so poorly hidden that they couldn't believe it hadn't been discovered faster. “Who the hell would have gone through all the trouble to build this?” Midnight wondered, “On top of that what can we expect when we get inside?”

Ochaco broke the silence between the three first. ”Should we go in?” she asked.

Midnight considered the option but Tsuyu answered before she could strategize. “There's an awful lot of body heat coming from within the building. Given that they seem to be mostly unmoving, they could be the kidnapped heroines, Ribb~. What concerns me is the two larger body heat signatures, we don't know anything about these villains. I really think we should come back with help.”

Ochaco nodded in agreement but Midnight shook her head.

“No,” she said, “We’re the scout force here but I think we’re capable enough to deal with this on our own. Those students could be in danger. We can’t not help them.”

Ochaco and Tsuyu looked unsure despite her confidence. They exchanged a look between them that said one thing. “This doesn’t seem like a good idea.” At the same time, they both understood that Midnight was in charge during this search. She had years of experience on them and if she thought them capable then they probably were.

“Ribb~. It’s not like we can let her go in alone either.” Tsuyu grumbled. She’d said it low enough that the statement was obviously only meant for Ochaco though Midnight caught it. The insight into the pair’s reluctance made her second-guess her gung-ho attitude.

Still, they nodded in unison, letting her know that they would follow her in. Midnight shook her doubts away. With them both on board they pushed through the double doors of the Nefarious Nursery.

II

Through the glass front doors of the nursery, a small waiting room awaited them. Off to one side were a few rows of chairs, directly opposite from which was a simple wooden desk where a secretary would sit if one were there.

Covering the sunshine-yellow walls was a childish mural of a sun with a giant smile. Under it, small forest animals such as a raccoon and a squirrel played together, prancing through a meadow. On the wall opposite the chairs was a bulletin board with no flyers attached to it.

"Looks like they don't have a lot of info to share with parents huh?" Midnight said jokingly.

Ochaco rolled her eyes, used to her teacher's playful nature but unamused given the possible danger. Meanwhile, Tsuyu just continued to scan the room, checking it for enemies.

Beside the desk were two doorways with large baby gates blocking the entrance. These baby gates were massive and obviously not meant for babies but rather were upsized so that they came to just above Midnight's head in terms of height. At about 6 feet tall, they were much bigger than anybody would need to keep a child contained.

Past the metal bars, they could see the yellow walls extending down a small hallway until it hit a bend and turned. The same cutesy dancing animal mural followed all the way down.

Ochaco placed her hand on the baby gate and removed the force of gravity from the blockade. It slowly floated upward until their path was completely cleared. Tsuyu dropped down to the floor, activating her camouflaging abilities. “I’ll scout ahead,” she whispered, scurrying off down the hallway.

“Wait! What about a plan?!” Ochaco whisper yelled after her.

With Tsuyu being her charge, Midnight panicked, grabbing out for a near-unseeable heroine. Her hand grasped only empty air, meaning she was too slow.

Rainy season Hero: Froppy

With her quirk, Tsuyu reaped the benefits of natural camouflage that made it easy to sneak her way through the short hallway and down into the main room of this so-called Nefarious Nursery. The two hallways connected into one at the end, creating a giant U out of yellow-painted stucco walls and a tiled floor. In the center of the conjoining hallway was a single archway that opened into a main room.

From her position low to the floor, she noticed the top of the archway was extremely high, extending to almost 9 feet up; the ceiling of the building was another few feet above that.

"Rib~ This place is huge, the roof has gotta almost touch the top of the warehouse." Tsuyu noted as she scurried forward. From her low position at the entrance to the archway, she scanned the newly visible space. At the same time, she kept as still as possible to avoid being seen.

The main room had pastel pink and blue striped walls with pictures of lettered wooden blocks interspaced all along them. On one wall near the back, she could see what looked to be rows of charts pinned directly to it, though she was too far away to see what they said.

The floor transitioned from a hard white tile to a soft forest green shag that Tsuyu felt her hands sink into slightly. Against the right wall, she could see two tables with multiple drawers that were topped with vinyl mats. In the lower cubbies of both these tables, colorful edges of linens or fabrics of some kind peered back at her. Along the left-hand side, Tsuyu noticed beds: two rows of five made for ten huge beds with bars that towered above any normal person.

“Ribbit~ must be cribs.” Tsuyu thought to herself, realizing the outside of this place wasn’t just for show—the whole thing was themed.

From her position, she couldn’t see who, if anybody, was trapped in the barred beds. She wanted to check but her eyes were drawn instead to two women standing in the center of the nursery. They were both unbelievably tall, standing at least at a solid 8 feet if not taller. Now the size of the doors and ceiling made sense: it was to accommodate these two.

One of them wore a knee-length floral pattern dress with a skirt that swayed whenever she moved. Blue, red, and gray roses emblazoned the fabric and bright red trim made the edges pop against her pale skin. The trim even framed a neckline that opened up to reveal her substantial cleavage and accentuated her hefty bust. The mystery woman's long and sturdy legs were confined within beige thigh-high stockings that disappeared into her flowing skirt, and red high heels that matched the trim and roses boosted her up another six inches—not that she needed it. Her fiery hair was pinned in a 1950s-style updo with a small rose beret that matched the crimson color of her lips.

The pale woman smiled and laughed to the other woman next to her whose outfit was much more provocative. The other woman almost reminded Tsuyu of Midnight; so much of her olive-toned skin was bared to the world as her legs and arms remained completely uncovered. "All she needs is a skin-toned bodysuit that doesn't hide anything." Tsuyu thought.

The woman wore a white lacy see-through pair of skimpy underwear. As she turned and shifted, Tsuyu could see the thin white string disappearing into the supple cheeks of her rump, and sitting above it was a small white lace-like triangle. This villainess wore a similar white negligee bra with elegant lace framing her own set of busty bosoms. Through the thin material Tsuyu could see the faint image of her dark areolas. Her midriff was covered by a blue satin corset with a similar floral design to her partner’s; it connected the white negligee into a leotard-style outfit, giving her somewhat of a villainous look, unlike the sweet-looking woman she stood next to. She danced back and forth on sharp, sparkly stiletto-heeled sandals, seemingly impatient about something. With diamond earrings and a necklace, her slutty outfit still had a strange look of class on her, and unlike her partner’s careful updo, her hair flowed down her shoulders with elegant blue-tinged ringlets at the bottom.

Both women shared the same red-lipped smile, it being the one similarity between their outfits. She carefully adjusted her dark-rimmed glasses as she talked to the paler woman in hushed tones just out of Tsuyu’s earshot.

To her dismay, Tsuyu realized she’d have to get closer to have any chance of catching what they were saying. She stayed low and inched steadily closer to the two women, the air in the room mysteriously silent save for the hushed tones they spoke to each other with.

*BRRRRAAAPPPPPPPPP*

A sudden and loud sound ripped her attention away from the two women as she whipped her head back to discern the source and whether or not it was an oncoming attack. Behind her she saw one of her classmates, their hands gripping tightly to the bar of the crib they were trapped in. It was Mina Ashido, the pink-haired acid-producing hero. She was in a squatting position, using the bars as support. A strained look was evident on her face as she seemed to be struggling with something.

“Ribbit~ Is she trying to escape?” Tsuyu wondered, “No that’s not it.” Something about the way Mina looked was wrong.

She wasn't wearing her trademark green and purple acid-splatter bodysuit and vest. Instead, her outfit had transformed into a childish onesie. Her vest now looked like a printed design rather than a separate piece of clothing, but the fur collar remained the same, puffing out around her neck. Usually, her bodysuit would end just above her breast line, but it now continued, connecting to the top and sealing her entire upper body within the strange new garments. Around her waist, she could see the bottom of the outfit puffed out and underneath the obvious snap crotch of her onesie, a thick pillowy diaper filled the space between Mina’s body and the seat of her clothes. The long leggings of the suit were gone, as were the heavy-duty specially built shoes she normally wore; instead soft socks with ruffles around the ankles replaced them, leaving the rest of her legs bare.

Her unruly and fluffy hair shifted as she struggled, her dark eyes squinting with tension. Then a loud *BLLLOOOOORRRTTTTT* filled the overly quiet room as Mina’s face turned from struggle to relief. Loud moans took the place of her straining grunts as the back of her onesie sagged lower and lower toward the mattress of her crib.

“She can’t really be—” Tsuyu started to think, appalled that her classmate could so casually let go. However, her thought process was quickly interrupted by a rumbling sensation in her own stomach.

She let out a loud groan involuntarily, blowing her cover because of it. “Rib~ Ohhhh My tummy hurts.” she said, grasping her stomach with a gloved hand.

Tsuyu was quick to snap back to attention when she felt the gentle touch of a hand stroking her back. She jumped away quickly from the couch and landed on her feet, preparing to fight.

Her eyes whipped back to see the woman in blue leaning over, her white bra was now gone, leaving her breasts fully exposed. Her face was masked in some sort of breathing apparatus that hadn’t been there before. Her eyes were solely focused on Tsuyu.

“I told you we had a customer come in. She was just playing hide and seek with us.” The woman in the dress chuckled,

“Oh, you were right, you were right. It's a good thing she got closer so your aura could affect her.” The bare-chested woman replied. “It seems like she’s firmly in its grasp, do you think you can turn it off so my tits don’t have to be hanging out?”

The red woman nodded. “Of course dear but you’ll just need to change her outfit quickly. She'll be making a mess of our floor soon if you don't.”

The blue woman moved closer, tapping the gas mask around her face. Tsuyu watched as the black latex material that covered her mouth began to change. Threads of white fabric snaked their way down her olive-toned breasts, spinning themselves back into the white lace negligee from before.

The froggy heroine tried to leap away from her encroaching opponent's grasp but found the span she could cover in a single leap was significantly reduced. Her legs felt weakened as she tried to jump away again, this time barely making it off the floor,

She looked for a way out but got distracted by her lolling tongue. While her tongue usually hung out of her mouth just a little bit due to its length, it was drooping out of her mouth so much more now. Usually, she could use the appendage much like a prehensile tail but Tsuyu found she was having trouble controlling it. On top of it all, she felt an excess of drool start to drip from her mouth.

“Ribb~ Wha haphenin? Why can’th I mothe righth?” Tsuyu said with a new and terrifying lisp. Looking down confirmed that she hadn’t been hit or injured anywhere. “Maybe it’s some kind of Ribbit~, poison?” she thought

While looking down didn’t reveal a wound, her eyes did come in contact with her outfit which had already started to change dramatically. In fact, she could pick out many similarities between her and Mina’s clothes.

Now rather than her normal tan-colored gloves, her hands were trapped in mittens: they were still the same color, but the buckles on her wrists had become locks. No matter how hard she tried, she couldn't maneuver her fingers enough to remove them. The straps and belt of her equipment were now missing, and various extraneous ruffles were added around her wrists and across the rump of her suit. Whatever material had covered her legs before was gone just like her equipment, leaving only leg holes and a snap crotch groin. Her boots and headband still remained the same, unaffected by whatever had altered the rest of her outfit and she could still feel the insulation within her suit that kept her frog-like body from falling into hibernation still there.

Tsuyu’s stomach grumbled again while an intense cramp in her gut caused her to keel over. This gave the blue villainess a chance to move in, and now the froggy hero could see exactly what she was doing. The woman placed one hand on the top of Tsuyu’s head while her other rested gently on her boots.

“Don’t you worry my sweet little tadpole,” the woman said, “Nanny won’t let you make a big mess on the floor."

Tsuyu's eyes grew wide with panic "Rib~ what does she mean mess?!" she wondered.

Nanny’s tone changed from sweet into sadistic in the band of a single pause, "You’ll be making a big mess in your diaper for me.” she said, and with her hands placed on the remaining unchanged parts of Tsuyu’s outfit, she started to morph the clothing with her quirk.

She quickly shortened the boots down to match the ruffled socks of the other babies in the nursery, opting to leave the cute frog toes on as part of her outfit. They’d become a very basic latex sock with some wire work in them for design, she made sure to leave no functionality to them whatsoever.

The material left over from the boots would become the outer plastic shell of the diaper with Nanny first changing the atomic composition and then forming it into the design she knew she wanted. The loose crotch of the onesie she'd created began to fill out as the crinkling plastic formed snuggly around Tsuyu's waist.

Next, she moved her hand from her captive's now bare thigh to the stomach of her onesie. The outer material squeaked a little as it changed into a rubbery latex and slowly became tighter around Tsuyu's body. She was removing the built-in insulation and placing it within the plastic shell she'd created to become the fluffy padding of the nappy, causing it to completely fill out the loose crotch perfectly.

She removed her hand from the new green and black squeaking latex of Tsuyu's outfit and wondered what to do with the goggles still on her head. The complex machinery within would give her plenty to work with, but besides that, the outfit was perfect already. She decided just to stuff all that material directly into her diaper, transforming the electronics within into more padding that made its way down her body and caused the thick bulk to expand more, pulling the onesie she was wearing taut.

"It'll probably be a big mess anyway." She remarked, watching the newly redressed Tsuyu squirm. Once she was done she stepped back, allowing her partner, Mommy Dominator, to examine her craftsmanship for herself.

The latex of Tsuyu’s new babyish hero costume bulged heavily from the monstrosity of a diaper underneath. Her legs were spread wide by the pillowy fluff and the round bottom of the protective underwear reached Tsuyu's knees without her adding anything to it. Mommy Dom nodded, happy with the transformation.

“Perfect, now we wait. She won’t be able to hold out much longer. My Motherly Aura quirk will have her filling that new diaper in no time. Then we can add her to the collection.”

Naughty Nanny agreed with a chuckle as she watched Tsuyu’s diaper slowly expand and balloon around her waist. “I just hope the diaper I made with Dress-up Doll will hold out. She’s already let her bladder go.”

Tsuyu was doing her best to keep herself together but Nanny was right—she’d let a flood of urine fill her diaper without a second thought. Not only was it without warning, but it made her body tingle in a highly pleasurable way. She’d never thought of diapers as being erotic, but now a strange horniness filled her mind like never before.

Focusing on the enemies in front of her was quickly becoming impossible. The growing need to poop was overtaking every thought she had.

She already felt herself letting out small farts that were muffled by the thick padding of her diaper. Tsuyu was losing the mental fight to keep from filling her nappy.

“Watch this,” Mommy Dominator said “I love when they just shit their mind into their diaper for the first time. It’s always the best.”

Tsuyu wanted to ask what she meant but there wasn’t time for the weakened hero to worry about the statement. Her sphincter failed her right at that moment.

*BBBBLLLLLLAARRRRRRRTTTTTT*

The fart emanated from Tsuyu’s backside as she started to push a massive load into her massive pampers. A scream of delight rose up through her body and out from her lips as she felt the burning pleasure rise up through her core.

Filling her diaper under these women was unlike anything she’d felt before.

Anti-Gravity Hero: Uravity

Ochaco heard the scream of her friend deep within the nursery, and against her better judgment rushed down the hallway toward the distressed calls of her teammate. She released her quirk's hold on the giant baby gate, bringing it crashing down in front of her instructor who called desperately for her to stop.

She didn’t care about Midnight being left behind. Instead, she was hyper-focused on the path in front of her. She’d need every bit of her anti-gravity power for the foe ahead and couldn’t waste it trying to hold up the giant gate. If Midnight didn’t make it through fast enough, that was her own problem.

With zero concern for her own safety, Ochaco rounded the corner down the short hallway and then the other at the archway. She examined the nursery room she’d just entered, seeing the changing tables to one side and the cribs to the other. But since Ochaco wasn’t on the floor, she could actually see what was in the cribs.

All of the missing girls from the various classrooms were lined up in the caged beds. Each and every one of them was thickly diapered and in some sort of onesie version of the outfit they’d come to the nursery in. Some of the classmates were sleeping while others sat awake.

She stood there flabbergasted as Mina Ashido ground her sagging diaper against the bar of her crib. In another she watched Momo Yaoyorozu raise her rear high into the air while the back of her diaper expanded and she moaned loudly into a pillow.

The sounds of moaning pulled Ochaco’s attention to the center of the room where Mommy Dominator and Naughty Nanny stood over the newly regressed Tsuyu. The rainy season hero had collapsed to the ground in a heap after her explosive orgasmic mess.

Ochaco knew nothing of what had happened to Tsuyu but she could see it’d left her on the floor much like a squashed frog. The sounds she was making could only have been some type of perverted pleasure and it distracted Ochaco enough that she stood dumbfounded for a moment.

After coming to her senses, she rushed towards the two massive women looming over her friend. With a practiced motion, she activated her zero gravity and launched herself upward whilst running, planning to use her combat prowess to pin the red-haired woman’s neck and bring her to the ground.

Just as her fingertips started to brush the strands of the woman’s hair, Ochaco felt a stiff poke hit her ribcage, sending her off course and away from her target. She looked surprised to see the woman in blue with her finger extended. It pointed at where Ochaco had been a moment ago and a cruel smile spread across her face.

The red-haired woman spun on one foot, sending the hem of her skirt upward as she twirled, flashing Ochaco a pair of red garters that sat above a pair of satin pitch-black panties and connected to her modest beige stockings. She too smiled at the girl who’d be the newest baby in their nursery.

They watched as her suit started to change from just a small poke from Naughty Nanny. The blue-clad villainess was only able to affect it a little bit. However, both she and Mommy Dominator had done their homework on the UA heroes. She knew that Ochaco couldn’t release the anti-gravity field on herself without pressing her fingertips together.

As the fabric of her hero suit twisted, they watched the arms of her outfit shrink to short ruffled sleeves, the remainder climbing down her arms and covering her palms in constraining latex mittens similar to Tsuyu’s. Through the bright pink shiny mittens, Ochaco tried to force her fingertips together in a vain attempt to drop down to the ground. Instead, she was floating helplessly in one spot, unable to push off from anything or pull away from the approaching form of the red-headed woman.

“You’ll want to step back or hold your breath Nanny, it’s time to start the process of regressing this one.” Mommy Dominator said. With three long steps, she was below Ochaco, just out of reach from her wild flailing, but close enough to have her pheromones start working their magic.

Nanny stepped away, making sure to leave the effective range of Motherly Aura. She knew better than to get caught up in Mommy Dominator’s quirk. The neurotransmitter she released would leave her a drooling diaper-addicted fool just like their captives, and she hadn't used her quirk enough to negate it yet.

The process always begins with an urge to use the bathroom in the affected target, but the crazy part was that it also re-wired their brains to associate using a diaper with intense and unbridled pleasure. These two together effectively caused the subject to dump all of their intelligence into their pants while they orgasmed into oblivion. Quirk control was usually the first thing to go due to Mommy Dominator’s brain affecting scent.

Sometimes, in rare occasions, Motherly Aura could even change quirks in ways that suited Mommy Dom’s purpose of making naughty heroes fill their diapers. Even with the red-headed giant standing clear of her target, the quirk itself had a ten-foot range and was already taking effect in Ochaco. All Mommy Dominator had to do was hum patiently to herself while she waited for the effects to start.

Ochaco threw punches and kicks at the red-haired woman standing below her, but with nothing to push off of and no gravity, she was floating ineffectually in one spot. Her enemy simply stood there, watching her bemusedly and humming nursery rhymes to herself.

Ochaco stopped, realizing the futility of her flailing and let herself hang limply in the air, instead opting to catch her breath and plan a tactic of some sort in the meantime. Her breathing had become ragged and hard as she’d semi-exhausted herself from her fruitless attack and only now did the words that the red-haired woman had spoken to the one she called Nanny set in.

“What did she mean by “regress” me?” Ochaco wondered while her eyes scanned the room. Finally, she rested her gaze on Tsuyu. Her friend lay on her back with her arms and legs splayed in all different directions and her crotch somewhat lifted into the air by the packed full diaper that was stretching the latex crotch of her onesie taut. Ochaco could see the buttons just barely holding together to contain the puffed padding.

She wondered why her friend's outfit was so different and how the two women before her were able to change Tsuyu’s clothes so quickly until she remembered the latex mittens now around her hands. Obviously, the scantily clad woman had the ability to change somebody's clothes just by touching them. That meant the red-haired woman must have made Tsuyu fill her diaper like that.

“It’s gotta be a proximity-based quirk! Just like Ms. Kayama!” Ochaco realized.

Despite having figured out her opponents' quirks she hung limply in the air. She could do nothing about her situation and the drawback of her quirk began to rear its ugly head. The normal nausea of being in anti-gravity was one thing, but the hard use of her quirk for so long normally caused Ochaco to puke from the strain.

However, floating there, she felt like something had changed. Her stomach grumbled and shifted in a different way than her normal nausea, Almost like she needed to use the bathroom…

That feeling only grew stronger in the minutes since she and the other woman had started staring at each other. Ochaco called out in panic to Midnight, hoping her teacher would hear any information she could. “DON’T GET NEAR THE RED-HAIRED ONE HER QUIRK—”

Her voice was cut off quickly as the blue-haired woman rushed forward, slipping her hand under the lip of her helmet and covering Ochaco’s mouth. “Now, Now. We can’t have you spoiling the surprise, can we? Mommy Dom, turn off your pheromones. I don’t want to end up like these two.” The red-haired woman, Mommy Dom, as Ochaco now knew her—stepped back, allowing Nanny the space she needed for her portion of the change.

The woman looked into Ochaco’s eyes with a sinister smile painting her face. “One breath is all Mommy Dominator’s Motherly Aura takes to start working, a person can come back from that. Heck, while we were figuring this out I accidentally breathed in a few times. You though, you took a lot of deep breaths. Unluckily for you, just catching a taste of that pheromone is enough to trigger a reaction. Lucky for me my quirk kills my ability to taste or smell for a little bit after I use it. I’m gonna make sure you’re all ready for what's about to happen because you just took a biiiig hit of what Mommy’s laying down.”

Ochaco glared back at Nanny with a furious look in her eye, angry that she was completely powerless before the woman. Naughty Nanny’s hands drifted over Ochaco’s body while she decided what to do with the young hero’s costume.

She started with the wrist equipment, connecting them to the latex mittens she’d created before and locking them around Ochaco’s wrists. She did the same thing with the ring around her neck, connecting it to the skin-tight bodysuit and turning it into a locking electronic collar. For the suit she pulled the long leg material upward, creating the same leotard-like bottom for Ochaco’s suit that she’d made for all the others. She made sure to widen it and leave plenty of room for the hyper-absorbent diaper the girl would soon find herself trapped in too.

Rather than the normal buttons for the snap crotch, she decided to leave the bottom closed, instead using the extra material from the legs to make her new onesie extra stretchy. “I might have to remove it all the way to change you, but those naughty little hands of yours won’t have any chance to remove your nappy.”

Mommy Dom piped in from behind her with a laugh, “Not that she’ll want to!”

Naughty Nanny joined her in her laughter while she used her quirk to transform Ochaco’s boots and helmet into the thick plush padding that filled the bottom portion of her onesie. The diaper was easily as thick as Tsuyu’s and Ochaco could only barely bring her knees together. Her thighs were spread wide by the sheer bulk of the padding now tightly situated around her nethers.

As Nanny removed her hand from Ochaco's face, the glass of the helmet twisted, morphing into a small plastic guard with a ring and rubber nipple before forcing its way into Ochaco's mouth. The newly formed pacifier replaced Naughty Nanny's hand in keeping her quiet.

She moved to spit it out only to find that her straps held it tightly in place, compressing the bottom of her brown bob haircut and cheeks. Without any of her nausea-reducing gear, her stomach was turning all around and upside down while she hovered in the air. The two women apparently didn’t care because they just fawned over how cute her new outfit looked.

Ochaco sucked on the rubber nipple in her mouth, annoyed at how ineffectual she was against the villains before her. It wouldn't matter soon though, as the rumbling in her stomach quickly grew louder and the cramps threatened to make the pain oppressive. Her urge to shit was becoming unbearable and the expectant looks on the faces of the women told her she was going to do it in that diaper whether she liked it or not.

Nanny’s eyes glittered while they stood watching before lighting up with an idea. She’d left Ochaco’s belt alone, unsure of how to use it, but the perfect solution came to her in that instant. With a playful wiggling of her fingers, she touched the device, feeling the vibrations from Ochaco’s rumbling gut. Using her quirk she started rearranging parts to suit a new functionality and when she was done she backed up, advising Mommy Dominator to do the same.

Another spasm sent Ochaco’s bowels into a grumbling cramp, this time causing her to let out a small fart into her pristine white padding.

*PPFFFTTTT*

When her stomach grumbled the belt reacted, and she felt the metal shell tighten, pulling its padded interior into her stomach, squeezing on her intestines and bladder.

“EEEP!” Ochaco squeaked from shock, feeling her bladder squeezed to the point where the pressure became too much and pee started to gush into her diaper. A racing flow soaked the front of her diaper, causing heat to spread across the front of her crotch and down toward her butt.

Nothing she did would stop it. Defiantly, she clenched every muscle she could but the pressure from the belt made the flow unstoppable. Even worse though was that she found that the warmth of the urine caused an ache in her pussy like she’d never felt before.

“Ohhhh Godddd.” Ochaco moaned, the feelings of horniness taking over as her nappy filled and expanded, the outer shell crinkling with every movement.

*PPFFFT FRRRT*

In that moment of weakness, Ochaco felt the tension she had applied to her sphincter weaken and a torrent of farts joined the stream of urine pouring into her diaper.

“HEY!” A loud shout came from the entryway, and Ochaco turned her attention towards the sound, desperate to get her mind off of the burning passion for her padding that she felt. The two villainesses turned too, curious to see who their next victim was.

There stood Midnight, flogger ready for action and an analytical eye scanning the room. “I thought I was the only kinky quirk user around, but this… This takes things to a whole new level.”

The 18+ Hero: Midnight

For Nemuri Kayama (Midnight) this was just a simple search and rescue operation, so why she was now staring down a massive baby gate with her two senior students gone into the clutches of god knows what kind of villain confused her.

“I guess I’ll handle this myself,” she said with a sigh, “and I’ll punish those two naughty little heroes later.”

Midnight’s sadistic side sparkled through her annoyed exterior as she started to look at the smashed gate before her. With the various sharp edges and exposed metal blocking her way at this entrance, she decided to run over to the other massive gate and heft herself over it. It was only a short climb, but halfway up a small electrical jolt ran through her body.

She dismissed it as static electricity and continued her climb. However, right as she was about to throw a leg over the top edge, a powerful shock hit her, sending her flying back into the empty waiting room of the nursery.

“Ohhhh that was quite a jolt, left me a little tingly.” She said flirtatiously.

Whatever sexualized demeanor she had was covering up her worry. She took a minute to catch her breath and considered how to vault herself over the electrified obstacle. The loud shout of Ochaco yelling: “DON’T GET NEAR THE RED-HAIRED ONE HER QUIRK-” snapped her back to alertness and she considered the pile of broken gate her student had left in her wake. She figured if she was careful enough maybe she could get through without getting jabbed by a piece of metal. It was certainly better than getting electrified again.

With a few careful steps, she managed to only get one rip in her skin tone bodysuit. After clearing the pile, Midnight rushed for the main room down the small hallway. Entering the main room caused her to slow because she was shocked at the amount of work that’d gone into its construction.

These villains had constructed a massive nursery, complete with high chairs, cribs, and changing tables. She was amazed at the quality of the craftsmanship. For a place that popped up in a warehouse overnight, it was built like a twenty-year permanent fixture. Nerumi looked over it all, noting the various mechanical arms and devices nestled in the ceiling above.

“Is this place automated?” she wondered. A sudden hope that she wouldn’t have to deal with the threat of mechanical arms along with whatever villains ran the nursery struck her. “That could be a problem.” Midnight thought.

The heroines in the cribs wrapped in the latex fetish onesies caused her to make the final connection she needed to understand this place’s purpose. She knew well the telltale signs of people lost in a foggy pleasure-induced haze—her whole identity was built around it after all.

Based on the drooling, open-mouthed expressions and the full diapers, each of these students was long gone in terms of mental capacity to fight. It would take plenty of retraining to regain their mental faculties, not to mention their ability to hold their bladder.

“That’s why they’re doing it, they’re thinning out the hero population one diaper-filling, brain drain at a time.”

Against the back wall and behind the highchairs she noticed the sets of rocking chairs and a large couch tucked into a corner. Behind all of them was a wall of charts. "What's with that corner?" she wondered, noting how strangely out of place it looked.

Once she’d taken in the entire space, Midnight felt good about approaching the pair in the center, thinking they wouldn’t have anything to surprise her with.

“That outfit may be a copyright violation…” she thought to herself jokingly, amused at how similar she and the woman in blue’s get-ups were.

The red-headed woman Ochaco had yelled her warning about seemed innocuous enough and just smiled while looking up at the flailing heroine.

Midnight, however, wasn’t about to underestimate anyone based on outward appearances, these two had made short work of both Tsuyu and Ochako. She tried to strategize, thinking about how she might be able to take the pair down. Somnambulist would only work if she was within five or so feet. She also needed to stay close for several minutes as these women would be less affected than her normal male opponents. If she couldn't get close to the red-headed woman, how would she be able to bring her down?

Another question raised in her mind though, one unrelated to tactical decisions, "Do these two just share an extreme AB/DL fetish?" she wondered. She had, of course, studied up on AB/DL in her earlier days, she was a “kinky” hero after all. That being said, it was never her cup of tea and she looked at it with passive disinterest.

Her eyes drifted to her two students, Tsuyu passed out on the floor and Ochaco floating in the air looking like she was losing a battle with a Hitacho magic staff™.

Her lack of a plan was undercut by the desperation on Ochaco’s face. She needed to save these two before they joined their other classmates. While she may have had the element of surprise, that was never her style anyway, so Midnight announced her presence loudly to the room with a playful tone, curious to see how the two villainesses would react to her presence.

“I thought I was the only kinky quirk user around,” she said, filling her voice with as much confidence as possible, “but this… this takes things to a whole new level!”

All eyes turned to her standing in the doorway. Her eyes were firmly placed on the two foes before her. While the women may have been significantly taller, she hoped she'd have an agility advantage on both of them.

The woman in red laughed at the sudden introduction, her partner shaking her head alongside her. “Well, at least you have the manners to introduce yourself before coming into the nursery un-invited unlike your two friends here. Of course, we already know who you are, Midnight.”

The woman in blue piped up, “I suppose we owe you the courtesy of an introduction as well.” She took a step forward, striking a sensual pose. She threw her body forward, bending at the waist and blowing Midnight a kiss down at face level. “I’m the Naughty Nanny. Here to punish these mischievous heroes who thought they could take us on.” as she bent over, Midnight watched her ample bosom heave inside her white lace bra.

“She’s straight up just copying my whole theme!” Midnight thought, feeling her confidence give way to anger.

The red-haired woman stepped up behind her, a single hand thrown up to cover a giggle from escaping her painted lips. “I’m Mommy Dominator,” she said, twirling a little as she did. “I’m here to regress you down to a helpless pants-wetter, so you feel right at home with the other babies.”

Nerumi laughed. “You two certainly are a strange duo, but I think it’s time to stop your kidnapping of heroes!” she announced.

Without giving them a chance to react she moved to rush forward, planning to snatch Ochaco from the air and reach the high chairs behind the two. This would give her something to hurl at Mommy Dominator, effectively pinning her so she could deal with Naughty Nanny. On the third step, she watched the black and blue-haired villainess rush to counter her move, an action she’d expected. Even in her heels, Nemuri was able to turn her body around the solid wall of a woman that was rushing towards her.

The only blow she’d landed was a gentle tap on her raised foot as she passed by her combatant. As Midnight brought her foot down, however, she discovered what her foe could do. Where the high heel of her boot was supposed to be there was suddenly nothing. She wasn’t ready when her foot landed flat on the shag carpet and it broke her stride. Her body tumbled, somersaulting ass over end until she came to a stop directly under Ochaco's floating form.

VI

Ochaco herself felt relief at watching Midnight enter the nursery and confront her captors. The distraction was even enough to just stop the raging horniness inside, which allowed her to regain composure and halt the massive load of shit she was about to deposit into her diaper.

When she watched Naughty Nanny tap Midnight’s shoe and change the heel to a flat, her relief disappeared because she knew it was all over. When Midnight slid directly under her, the pressure in her gut became too much and the rumbling of her stomach caused her belt to retighten around her waist.

*FLLLLLLLLOOOOOOORRRRRRRPPPPPPPPPPPP*

Feelings like fireworks going off behind her eyes lit up Ochaco’s brain as she forced a smelly, slimy mass of shit from her body, instantly achieving a new kind of relief. It started to pack into the back of the diaper, causing it to balloon outwards aggressively before sagging below her, slowly reaching her former teacher's face. She screamed as the sensation of her spasming asshole sent a blaze of satisfaction through her cunt.

“OHH FUCK!” she cursed. Nothing in this world had it felt as good as shitting herself did at that moment. Something about feeling the heat of her squishy mess being held against her bottom and pushed upwards by the latex onesie drove her wild. The plastic-shelled nappy was trapped by her sealed leotard bottom, straining to grow and expand in its confines.

Ochaco bucked her hips, trying to find anything to grind against, to bring some sort of frictional force up into her diaper and push the squishy absorbent padding into her groin. To her delight, somewhere in the process, she finally found what she was so desperate for as the edge of the squishy padding caught a raised bit of surface on the ground.

She remained oblivious to it being her teacher's face. The weight of her diaper and a slow loss of quirk control had her falling, lowering her still swelling messy diaper down onto Midnight’s horrified face.

Standing above both of them, Mommy Dominator smiled, “Guess it's about time to-”

“No!” Naughty Nanny cut in, “Let me change her outfit first, then you can regress her.”

Mommy Dominator shrugged and allowed Nanny to move forward and lay her hands on Midnight’s fetishwear hero suit.

VII

Midnight found herself unable to move from the shock of watching her student fill the diaper she'd been trapped in so shamelessly, and so much at that. The way the padding ballooned and filled out it looked to be more than Ochaco's small body could hold on any given day.

What was worse, she realized that slowly the pink and black stripe of the latex outfit was coming closer to her face both due to the diaper continuously filling out and Ochaco slowly lowering down on top of her.

She moved to roll out of the way of the brown balloon closing in on her head, only to find it was too late. The anti-gravity effect Ochaco had placed on herself had failed and as she slipped into pleasure she began smothering Midnight without care.

The latex covering the outer layer of padding did nothing to halt the smell that assaulted her nostrils, and Ochaco continued to fill the messy padding over her. Once her face was fully encompassed, Nemuri felt the mass shift on top of her in a rough back-and-forth motion over her.

“Oh fuck, she’s using my face to get off, isn’t she?! Shit, can’t breathe, can’t move.” She was panicking under the weight of her pleasure-addled student. Midnight knew from experience that her air would run out fast.

The smell of Ochaco’s mess alone was enough for her to not want to breathe. However, as the shifting of the plastic shell crinkled and the warm mush caught and held within shifted, her nose was forced to inhale the sour smell of the girl’s mess as she ground her wanting pussy into her teacher's face.

On the outside of the situation, Naughty Nanny placed her hands on the leather leotard of Midnight's hero suit while considering how to morph the outfit for her to fit into the nursery.

“Maybe it doesn't have to be as drastic,” Nanny said, “a light touch might be nice. She is already dressed so naughty."

Stuck underneath the diaper, Midnight felt the hands shift around her body and she started to panic; she had no idea what was happening, only that she could feel the slow soft touch of hands running around her body. Tickling fingers cupped her breasts and hips in gentle motions before clamping down; one on her wrist and another pressed on her stomach.

The normally tight bottom of her leotard loosened around her hips, and she felt the weight of her knee-high boots relieved from her feet. The jangly cuffs on her arms also disappeared in the process. It was a strange feeling having the fabric of your clothes shifting around your body while you were still wearing them, especially when they were becoming something else.

Nemuri couldn't quite describe it, not with the air running out under Ochaco’s diaper. When she felt the skin tone bodysuit that normally concealed her nudity start to shrink and disappear, only one thought came to her mind.

“Gotta activate Somnambulist!”

She knew her quirk would shut down the villainesses fast if she could just release the sleep-inducing aroma from her body. The outer bodysuit disappeared completely from around her body, exposing her breasts to the open air of the room. The material danced along her skin to the lacy black underwear that she always wore under her hero suit. It too started to slowly expand and change.

The material from the other parts of her costume merged with it, puffing out her normally skimpy panties into a whole new piece of clothing.

Funnily enough, it was something far more protective than what she’d been wearing before. Her legs started to spread as the new bulk of her diaper grew more and more between her legs.

On the outside Mommy Dominator watched as Midnight struggled weakly under the massive diaper around Ochaco’s hips, her student having let all her weight fall into the mess as she moved desperately on top of her.

Naughty Nanny was preoccupied with changing her outfit, simply widening the crotch of Midnight’s outfit and adding her traditional snap crotch to it, turning what little material she could into a diaper to rival the ones her students were given. She left the top part of the outfit alone, leaving the black leather strap that connected her corset and collar between her now bare breasts. Her stockings and garter also remained, highlighting the hero’s long graceful legs as they extended from her now thickly diapered waist.

“Seems like a rather subtle job for your work Nanny.” Mommy Dominator commented.

Naughty Nanny turned back to her with a smile. “I can appreciate a good outfit when I see one, just needed some minor adjustments.”

Back under the moving mess, Midnight

gasped, using the last ounce of her strength to exude her quirk through her now bare skin.

The similarities between Somnambulist and Motherly Aura were eerie. Nerumi herself released an aroma or pheromone like Mommy Dominator did, except hers put her targets to sleep rather than regressing them mentally.

The main drawback was she had to be showing plenty of skin for it to work. This wasn’t a problem for her though, she wasn't ashamed of her sexuality and had no problem dressing or acting in such a manner outwardly.

The other drawback was that the effects of her quirk worked slower on women. As the world around her started to go dark, Nemuri felt Ochaco’s weight suddenly shift in a different direction before completely falling off of her face. A loud thud followed by a snoring sound came from her student as she hit the ground.

She blinked, her eyes taking several seconds to adjust to the bright lights of the nursery after having been trapped under Ochaco. Looking down revealed changes to her outfit and she felt herself cringe in a disgusted manner at the way Naughty Nanny had altered her hero suit.

She locked eyes with the twisted tailor, feeling first anger and then surprise, a realization struck her.. “Shouldn’t you be passing out just like her?” Nerumi asked.

“No," She answered "Probably won’t before you’re done, either. Foolish little one, did you think I’d just let your quirk run rampant?”

Midnight shook her head in shocked disbelief. “Why isn’t it working!?” she wondered, “If Ochaco is passed out, shouldn’t these two be?” She looked up to the other woman, Mommy Dominator, to see her eyes were in fact half-lidded but she was still standing strong.

“I wonder which will win out first: Mommy Dominators quirk or yours? Either I get to see you totally regressed or I get to give her a new outfit. Either way, I win.” Nanny said.

Midnight stuttered out a quick “But why not you?!” in a panic, willing her legs to work so she could escape and get help.

The evil duo laughed and Mommy Dominator answered. “Nanny’s quirk makes it so she can’t smell or taste for a while after she uses it. With all the heavy use today, she’s totally immune to both of us right now cutie.”

The horror spread on the dark-haired hero's face as she realized that Mommy Dominator’s quirk must have turned Tsuyu and Ochaco like this, and she was in range of that power now! The sudden pressure of a full bladder and a slight rumbling in her stomach quickly confirmed her suspicions.

Somnambulist was a feeling for Midnight. When the sleep-causing pheromone leaked from her body she could actively feel it, so when it stopped suddenly it felt like a part of her was suddenly missing. Her sleep-inducing aura was completely gone, and Mommy Dominator’s quirk was in full swing in her system.

Nanny stood, pulling her face away from Midnight’s to lift Ochaco into her arms. She cradled the sleeping student in her arms while Mommy Dominator did the same for Tsuyu. Nemuri saw an opportunity while their backs were turned to escape and pushed herself up onto her legs. Her foes hadn't left her with much in the way of clothing, having instead put it into the thick padding around her waist. Midnight now ‘walked’ with an exaggerated waddle, and as she tried to make a break for the door she found that her padded rear swung hard with every step she took.

The way the bulk of the diapers spread her thighs made it impossible for her to get a solid stride. Even if she could make it through the archway, the nagging urge to pee was only aggravated by her quick movements and sudden jostling.

*PFFFT, PFFFT, PFFFT*

Each step she took let out a small fart, and every time Nerumi felt Somnambulist activate for a brief moment. "No, It can’t be," she thought, pushing a little to allow flatulence to escape and feeling her quirk activate again, "It's my... farts now?"

She understood that any chance she had to use her quirk was effectively muffled by the thick diaper she wore. The light of hope was slowly fading from the hero.

Still, she kept running, feeling liquid sloshed around inside her full bladder. She got so close to leaving the nursery room but just as she stepped to the archway she felt her body let go. The raging river of piss soaked into the padding around her waist.

“Shit, SHIT, SHIT!” she called, enraged with her new and sudden incontinence. The sodden padding became more of an obstacle for her now as the diaper steadily swelled. The more liquid her body added to it the more pronounced her waddle became.

Not only was it slowing her down but the squishing of the material between her thighs and groin started bringing forth feelings that she'd rather not have distracting her while she was trying to escape.

Gritting her teeth with each step, Midnight powered forward. She was the 18+ hero after all. A little eroticism and promise of orgasmic pleasure weren’t enough to stop her dead in her tracks. Unfortunately for her, Motherly Aura was stronger than she knew.

The horny desires created in somebody who'd used diapers under its influence could drive a person insane, or as the two nursery owners liked to put it “Made them shit out their intelligence like naughty cum-addled babies.”

Unconsciously, Nerumi’s steps slowed until she was standing before the great glass doors of the nursery. The outside world and freedom were only a few more waddling steps and a yell away, but she couldn’t make the final movements to go out the door. The intense feeling of soaked padding rubbing into her groin made her rethink escape for just a moment.

The hesitation was enough time for Mommy Dominator to catch up to her and watch with a satisfied smile on her face at Nemuri’s pause at the doors of the nursery. The massive redhead stepped up behind the padded heroine. Grabbing her by the sides and lifting her into the air.

“Noooo.” Midnight whined, realizing now how close she was to freedom and how quickly it was gone.

VIII

Mommy Dominator swung Midnight into the same cradling position she’d put Tsuyu in moments before, handling her body like it weighed nothing to her. Just like that, all her efforts were for nothing and she was carried back into the nursery.

All the movement brought new churning and rumbling to her gut, but she held strong, determined to hold back that last part of her dignity.

As they returned to the nursery, Midnight started to scan the room, looking for a way out before she was completely lost like her students. Sitting on the couch in the back corner of the room was Naughty Nanny, both Ochaco and Tsuyu sitting on either side of her, their heads propped up by her hands so their faces sit at breast level.

Above the cribs mechanical arms moved, transferring messy students from cribs to changing tables to be cleaned and rediapered before the arms placed them into high chairs.

“Looks like nap time is over, which means it's time for lunch, then playtime.” Mommy Dom explained. Midnight watched as long tubes extended down from the automated ceiling, presenting the nipples on the end for the nursery’s residents to suckle on, allowing a flow of some mysterious liquid into their bodies.

“You can’t get away with this, somebody is going to find and stop you.” Nerumi grumbled through gritted teeth. The cramps running through her body became worse and worse by the minute and she now had to clench everything she had to hold back the inevitable.

Mommy Dominator looked down at her with a very sweet caring expression. “And we’ll just pick up and move like we've always done in the past. Do you think this is the first nursery we've established? No, me and Nanny have a system. You pesky heroes need to be taken down a peg so Nanny and I regress a bunch of you then you’re sold off to people who want to take care of big horny diaper babies. The same goes for the furniture.” she explained, “We’ve gotten very good at it over the years. In fact, with you three added in, we have a full roster so we will disappear once you’re all sold off.”

Midnight couldn’t believe her ears: this wasn't just some small-time villainy by two random quirk users. She'd stumbled into a massive operation that now she might be stuck as part of it. A hard fear started to take over in her head and she looked more fervently for a way out.

Even running wouldn’t get her far. Nanny and Mommy Dom were ready for it now and with her waddle, she had no chance of getting clear of them.

When her captor sat, Midnight noticed the moisture on her arm. At some point along the way the front of the red-headed woman's shirt had been splashed with something or... no, it was coming from the inside of her shirt? She was lactating?!

As the woman lowered herself Midnight turned her head to see Naughty Nanny and her two students. Now that she was right next to them she could finally see that they weren't just laying there with their heads propped up. They were moving, drinking. The woman in blue had lowered her white lace bra so that the two girls, still trapped in their messy diapers, could be breastfed.

Midnight turned her face to meet Mommy Dominator’s above her. “Don’t worry, you’ll get your fill too.” the Red-headed woman assured her.

She lowered the steep neckline of her dress, revealing the milky white skin of her voluptuous breasts, each tipped with perky pink nipples standing at attention. From both, small drops of milk leaked down into her pulled-down dress. Something within Midnight’s mind told her to latch on, that the liquid would taste better than anything she’d ever drunk or eaten before.

“Uhhh” Mommy Dom groaned, “The worst part of my quirk is how full it makes my breasts. They’re so tender.”

Midnight regained some composure: so that was her drawback, her baby-making quirk caused her to lactate. Midnight supposed that made sense in a way. The pheromones must react differently with her body somehow. The real question was how Naughty Nanny was doing the same. She wasn't dealing with the same quirk drawback so how was she able to breastfeed the two attached to her?

These questions would go unanswered for Midnight though, as her head was turned and one of the woman's nipples was forced into her mouth. Mommy Dom kept a hand on the back of Midnight’s head to stop her from escaping and the command from her brain to bite down as hard as she could was quickly overridden when the sweet taste hit her tongue.

Automatically she hallowed her cheeks, drawing in as much of the saccharine, warm milk as she could. A deluge filled her mouth, leaving Midnight to swallow it greedily. This continued for a few minutes until the flow dried up, leaving her sucking away at nothing until Mommy Dom switched her to her other breast.

Without thinking, Midnight clamped down again and emptied it as well. This of course only worsened the gurgling cramps and pain in her excessively full stomach. She was coming to realize how unbearable the feeling was as the milk-drunk feeling disappeared.

The pressure in Midnight’s stomach was unbelievable and something about the breast milk she'd drank was only making the situation worse as it roiled within her gut.

“W-what’s happening, what’s in that breast milk?” she asked.

Mommy Dom carefully pulled her away and set her on the ground. Midnight stood and clenched her stomach, fighting to talk against the pain.

“Well little one, I constantly produce colostrum in my milk. It's great for your body but your poor adult stomach doesn’t react so well to it. I’m amazed that you kept that diaper clean for so long but I guarantee that you won't be able to for much longer.” Mommy Dom explained

Midnight continued to shift uncomfortably, turning her gaze to see if her students were faring any better. Both of them lay with their head in Naughty Nanny’s lap burbling happily while she stroked their hair. Even distracted Midnight could see the strain on each of their faces as they started to push automatically.

*FLLLORRRP*

*BLLLORRRRRRRRTTTTTT*

Tsuyu went first, then Ochaco, their diapers continuing to expand. The latex of their onesies stretched as they packed their pampers full. For Tsuyu the snaps at her groin eventually gave way, freeing the crinkly padding within to sag and droop, now a brown bean bag chair around her waist. Nanny shifted her hand from their heads down to their groins, giving the two something to hump against as they finished their messes.

Midnight herself felt her body at its final limit and she turned to try and make a break for the door one last time, hoping to abandon the now cold, wet padding around her waist in the process. She only made it two steps before she buckled at the knees into a squat.

*BLAAAAAAAAARRRRRRTTTTT*

Her bowels were no longer able to stay clenched and instead they started the natural process of pushing mushy waste from her body, only for it to be caught by the damp, absorbent padding around her waist. Wave after wave of shit forced its way into the nappy, causing it to expand as far as it could, stretching the outer leather layer of her onesie before the diaper could stretch no further. Instead, shit began filling into any and all other spaces that it could, piling into the front and around her waist and groin.

The feeling of her bowels working hard to expel so much molten waste from her body was sending surges of ecstasy throughout her entire being. Midnight felt her body tread that edge, just before she was to lose herself in the pleasure of her mess. Now, after she finished, her diaper had stretched to nearly reach her ankles, stained and strained far beyond what a normal incontinence garment could handle. The added weight alone threatened to pull down her body as she shook, fighting off the pleasurable feelings as best she could.

“Y-You think that’s enough to beat me?” she threatened, her breathing heavy and ragged. “I’m Midnight, the 18+ hero! I’m not gonna be taken down by being dominated by a couple of fetishy giants. I do the dominating!”

She turned to try and break for the archway only to bump into Mina, who now stood in front of her, having been changed and fed. Nemuri quickly lost her balance and fell back into the squishy mess beneath her. There was enough there that she was fully propped up, sitting comfortably in a wonderful world of mushy euphoria. The primal urge could be ignored no longer, and she threw both hands into the mass of crinkly padding, hoping to apply any pressure to her now aching pussy.

“Shiiit, I need to cummmmm!” she screamed, all previous declarations and plans forgotten as all she could think of was pushing herself over the edge.

Mommy Dominator and Naughty Nanny watched on as the mechanical hands took away Tsuyu and Ochaco so they could be wiped, powdered, lotioned, and changed into new diapers before they were put onto the playroom floor, where they’d fill them again and again.

“She was a tough one.” Nanny remarked, pleased with how fervently Nerumi was rubbing her diaper now.

“Yeah,” said Mommy. “But I figured we could break her. After she cums this time, there’s not gonna be any resistance left. Look, she even has a playmate.” She pointed to Mina, who Midnight had bumped into. The pink-haired hero finished a squirmy orgasm of her own as she squatted and filled her diaper. She then pulled herself on top of Midnight and began humping her own messy padding into her teacher’s, driving her deeper into an orgasm that finally made her lose control and push the last of her will and resistance out in the form of more stinky mush.

“Do we have a buyer lined up yet?” Nanny asked.

Mommy Dom shrugged. “Unfortunately no, we might actually have to release most of them but I bet I know a certain kitty who’d love Little Nerumi here.
