Summary:

Story for Snakeman. This is a continuation of an older story on Deviantart found here: https://www.deviantart.com/andsoisaidmrglrg/art/Midnight-s-Mountainous-Mommy-811381280

Here, we continue with Midnight being told that her new life as a baby is going to be a little more permanent. However, despite actually enjoying the treatment, the former pro hero isn't going to cut her mommy any breaks. If she wants a baby, she'll get a baby.

Work Text:

It had been a few months since Midnight’s fall from grace as a pro hero. Just when she thought she couldn’t stoop any lower than being Mt. Lady’s sidekick, the R-rated hero found herself proven wrong rather quickly.

The first few days were fine other than the fact that she was parading around the city dressed like the world’s biggest baby, but as the days went on, the treatment only seemed to get more and more intense. It wasn’t long before Midnight wasn’t even allowed out of the office to get something as mundane as coffee, the older woman forced to sit inside of the agency all day and act like mommy’s precious little stinker. It was a surprise that she was even allowed to go home after all was said and done for the day but having to wear the baby stuff even after work might have been the tradeoff.

Regardless, Midnight knew that all she had to do was endure this longer than Mt. Lady could dish it out. So what if she had to poop herself like a baby and play with toys all day without having to worry about the next villain attack. Actually, in her mind, that didn’t sound like so much of a bad thing. In fact, it sounded like a rather nice vacation since she would be waited on hand and foot. The only downside was that her “mommy” in this situation wasn’t even in her top ten picks if she had to choose.

With that thought in mind, Midnight found herself starting to relax more and more as the days went by. Of course, being a rather attentive mother, Mt. Lady started to notice that there was something going on with her baby girl.

“Well, well, well. Someone has been in a better mood recently.” The pro hero stated as Nemuri walked through the door of the younger woman’s agency. “I guess you’ve finally started to accept your role as my big baby. I knew it was only a matter of time before you learned that’s all you are.”

The babified former pro hero knew that her mommy was right in her assumption, but she sneered at it regardless. “Nonsense. I’ve merely gotten into a rhythm. Things are a lot easier when you aren’t constantly changing things around just for me you know.” Midnight said before toddling away from her employer so she could get to her nursery and start her day. It was bad enough that she could hardly walk straight with such a thick diaper between in her legs, but her reply had even less of an impact since she was wearing a super frilly pink dress to boot.

“You know, you make a really good point.” Mt Lady said as she watched the older woman waddling past her, only to grow ever so slightly larger before scooping her baby girl up. “That’s why I think that it would be much better if you were to stay here at the office for the time being. So that means that even after a hard days work of pooping your pampers, you can stay here with mommy and continue to be my adorable little pamper packer. How does that sound?” She cooed as she moved Nemuri into a cradle position, the young woman making silly faces and doing her best to tickle the diapered woman in her arms as she did so.

“Wait, you can’t be serious!” Midnight exclaimed as she tried to fight off Mt. Lady’s arms, but her mommy’s strength was too much for her to handle and she swiftly found herself giggling at the little pokes and prods here and there.

“See? I can already tell you’re enjoying it already. Now let’s go get you into your nursery. Mommy has some ground rules that she needs to set now that you’re going to be ‘working’ around the office more.” The pro hero continued to coo as she carried her diapered charge out of the main office area and up to Midnight’s nursery which was conveniently placed in a hidden room next to Mt. Lady’s office.

When the pair arrived, the younger woman did her standard thing and placed the diapered woman in the playpen, checking her sidekick’s diaper by pulling back the waistband before letting it snap back into position so she could explain what these new rules were.

“Alright, so rule number one is that you are to address me as mommy.” Mt. Lady stated firmly, only confusing the padded woman sitting on the floor.

“But I already do that.” Midnight bluntly responded, unsure of why her mommy felt the need to reiterate something as basic as that.

“Yes, but you are going to do it no matter what the circumstance is. If you call me anything other than that at any point in time, I will make sure to remind you with a firm spanking.”

Midnight sighed. There really was no point in arguing with the pro hero and trying to do so was only going to end up with her getting needlessly exhausted. “Okay, mommy.” Nemuri simply stated, making sure that she added mommy at the end to let Mt. lady know that she understood the new rule in place.

“Good girl.” The younger woman praised. “Now then, onto rule two, and that is no more walking. Period.”

Again, Midnight just went with it and nodded her head to show she understood. After that, her mommy just went off listing a plethora of rules, most of which she was already doing, just to a little more of an extreme like being unable to feed herself or using nothing but baby babble. If it had more than three syllables, odds are it wasn’t a word the older woman could use.

“Now then, any questions?” The younger woman asked as she knelt down closer to her baby girl.

“No, mommy.” The diapered woman replied in a cutesy babyish tone since that was also a new rule that she had to follow less she end up punished. It wasn’t that she didn’t want to get punished at all, it was just that the older woman wasn’t in the mood to deal with such an inconvenience at the moment and just wanted to spend some time winding down before she started winding up her mommy.

Smiling at the response, Mt. Lady gave her padded charge a little kiss on the cheek before leaving the older woman to play with her toys while she took care of some “big girl things” as the younger woman put it.

With her mommy out of the room though and no other distractions, Midnight looked around the playpen until she saw a pacifier. Once her eyes locked in on one, the older woman smiled before crawling over to it and popping the rubber soother in her mouth. She said she didn’t accept her new role, but she never said anything about not enjoying it.

With the pacifier secured, Midnight gave it a couple of suckles before crawling off to a different area of the playpen. There was so much room that it was an understatement to just call it another part of the room when it could have easily been one on its own. Other than the big toy chest off in the corner, there was an area filled with plushies and one that was a little more spacious in case she wanted to play a little pretend. She wouldn’t want anything getting in her way after all, and she could easily recreate any sort of scenario she wanted with the stuff available from the toy chest. However, Midnight wanted to do something a little more dumbed down.

Crawling towards the toy chest, the older woman took her time sorting through all the various toys that where in there until she found the simplest, and possibly her most favorite toy of all, a rattle. Once she had found the circular shaped noise maker, Nemuri looked at it with a glimmer in her eyes before grasping it tightly and taking it over to the pile of stuffed animals.
When she made it to the massive pile of plushies, the older woman plopped down on her crinkly rear and fell back onto the fluffy pile. She was already planning on just playing with it, so she might as well make herself comfortable.
After she was totally nestled in, Midnight lifted up the rattle till it was right in front of her face, the large piece of plastic already making a bit of noise as it was lifted into the air. Once it was in position, the padded woman held it in place for a short moment before giving the rattle a good shake.

The loud and simple noise that came from it tickled Midnight so much that she couldn’t help but giggle gleefully, kicking her legs outwards and causing her diaper to crinkly from underneath her fluffy skirt. From there, Midnight shook the rattle without a single care in the world, anything that wasn’t the sound of her rattle filling the air falling flat on her ears.

The padded woman was so engrossed in the activity that she didn’t even hear the hissing coming from the front of her diaper as she wet herself. She certainly felt a need to go, but it was so subtle that it easily passed under her radar, almost as if she were completely incontinent now. There was at least some part of her that knew when she was going to go, but because she was forced to wear and use her diapers for so long that it was just natural at this point. Because there was no point in holding it, the need to tell when to go just wasn’t important enough to care about. It might become a problem once the older woman gets her hero license back, but for now, it wasn’t important.

A few hours had passed and Nemuri was still contently playing with her rattle, her eyes practically glued to the plastic toy as its deafening noise continued to resound throughout the nursery. Within that time, Midnight had managed to wet herself at least two more times, her crinkly undergarment now swelled to its utmost capacity and it hadn’t even been messed in yet.

“So that’s what I’ve been hearing this whole time! I might have to get a little more soundproofing in here.” Mt. Lady suggested as she walked over to her padded charge. “Of course, it would be harder for me to hear you if you needed me, so perhaps I should add a baby monitor in here as well. That way I can keep an eye, or rather an ear on that padded butt of yours.” The younger woman cooed teasingly before letting out a small giggle.

Midnight didn’t seem to have absorbed a single word of what her mommy said though, the diapered woman too preoccupied with her toy to focus on much of anything else really. Mt. Lady didn’t care though. In fact, she thought it was rather precious. It was almost a shame that she had to stop it once she noticed how full her baby’s diaper was.

“Woah! You really soaked that diapee of yours huh? Guess I had better change you before you start to make a puddle.” The younger woman commented before stepping into the playpen to get the soggy woman out, using her quirk to grow ever so slightly larger so she could lift her baby up with ease and carry her over to the changing station.

Midnight was a little agitated by the abrupt halt to her play, so she was a little fussy about being picked up. Her mommy however was more than strong enough to stop her rowdy little rug rat before she got too out of control, but even with restricted movement, Nemuri wasn’t about to be whisked away without giving her mommy a piece of her mind.

“Hey! I was pwaying!” The diapered woman lisped from behind her pacifier as she tried to bonk Mt. Lady with her rattle.

“I know sweetie, but mommy needs to get a new diapee on you before you leak.” Mt. Lady replied in an attempt to reason with her diapered charge, but Midnight just refused to yield.

“No! No changie!” Midnight protested, not wanting to change out of her diaper just yet. There really wasn’t a reason for it other than the fact that she was interrupted, she just wanted to be put down so she could play some more. That and the feeling of a wet diaper was actually rather pleasant, especially when it was as drenched as it was. The weight of it alone was more than enough to cause the crinkly undergarment to sag to the point that it revealed the top half of Nemuri’s butt.

“Are you sure that’s what you want?” Mt. Lady asked in a more serious tone, making sure that this was absolutely what Nemuri wanted.

“Yes!” Midnight exclaimed like a child on the verge of a tantrum if she wasn’t put down in the next few seconds.

“Alright, if you say so. But don’t come crying to me when you get a nasty case of diaper rash.” The pro hero responded as she set her baby girl down on the changing station.

Midnight then looked up at her mommy with a confused face. She was just told that she wasn’t getting a change, and yet here she was still placed on the changing station. It became clear what the younger woman’s objective was though when the front of her soggy diaper was cut open with a small knife.

Once the front had a large cut from nearly front to back, Mt. Lady grabbed a new, thicker, and bigger diaper and laid it under Nemuri after she had unfolded it. When the new diaper was centered in place, the younger woman pulled the front over the used diaper and held it firmly in place as she went to grab one of the tapes.

Just before the blonde could secure one of the tapes, Midnight decided that she wasn’t going to let this go without a fight, so she started kicking her legs a little to make things just ever so slightly harder on the pro hero.

While she thought that it would be a bother for her mommy, Mt. Lady actually smiled a bit when the resistance started. After all, it wouldn’t be any fun if her baby girl didn’t act out from time to time. Besides, it was nothing more than a minor nuisance. All the younger woman had to do was grow larger so that she could easily grab both of Midnight’s legs with one hand while the other taped the diaper snuggly around the black-haired woman’s waist.

Finished with the layering, Mt. Lady shrunk down to a much more reasonable size and lifted her baby girl off of the table, outstretching her arms and giving the diapered woman a full look over to see how cute her charge was in her double diapers.

“Aw, don’t you just look absolutely precious in your thick diapee!” Mt. Lady cooed as she lightly shook Midnight, pursing her lips and continuing to make infantile noises at the padded woman since there wasn’t anything her baby girl could do to stop it.

Still a little miffed about being taken out of the zone, Nemuri figured that now was the time to unleash her ace in the hole. She was planning on saving this for later, but with her stomach already feeling like it was about to burst, now was as good a time as any.

Staring her mommy directly in the face, the black-haired woman let out a grunt as she started to strain her face, her arms and legs pulling into her body and shaking violently as Midnight struggled with all her might to force something that had been brewing in her for a while now out into her diapers.

Within just a few short seconds, a loud brassy bout of gas ripped through the air before the sounds of crackling and crinkling started to join in. A small bulge began to appear in the back of Nemuri’s diaper, the slimy sludge pushing against the drenched walls of her first layer with such force that it was easily visible despite the overall thickness of the undergarments combined.

After another grunt, the bulge exploded in size, bulging the crinkly undergarments out with a large spherical bulge that only continued to grow. Because of the tightness of the newly added diaper though, the protrusion just continued to grow until it was forced down into the bottom of the absorbent undergarment. The foul-smelling mess didn’t manage to make it too far before it stopped however, the mud-like sludge just barely backing it to the front while the rest sat firmly in the back.

Finished with her soiling, Midnight let out a sigh of relief before relaxing her body, her pacifier falling from her mouth as she giggled and kicked her legs in delight.

“Hehe, I go boom-boom in diapee!” Nemuri cooed as her giggle turned into a laugh, the older woman thinking that now she was definitely going to have to get changed with how much she had just unloaded into her diaper. Not only did it have a very high chance of leaking now, but the odor it produced was absolutely awful, it’s noxious fumes already starting to permeate the air and make the room smell like a diaper pail. Unfortunately for Midnight, her mommy wasn’t in the mood for a second change in a row.

“Pew yew! That diaper reeks! It’s a shame you’re not going to be getting a change for a while though, so I guess I’ll just have to spray some air freshener in here later.” Mt. Lady cooed as she turned her head in an attempt to get her nose away from the source of the foul-smelling aroma.

“B-but my diapee tinky!” Nemuri lisped in shock, thinking that her mommy must be out of her mind to just let her baby girl sit in such a messy diaper.

“It sure is, but someone wanted mommy to put another diaper over her soggy diapee, so you’re not getting out of that one till that second one is all filled up.”

“B-but…” The messy woman trailed off; not really sure what else she could say that would make her mommy listen to her.
“No buts missy, unless you want a red one that is.” Mt. Lady threatened as she set Midnight back down in the playpen with a disgustingly squishy squelch.

“N-no mommy.” Midnight stuttered as she felt the slimy muck crawling against her skin, small pockets of air bubbling and splattering as they popped from being smeared around her backside.

“Good girl.” The blonde woman replied with a smile before she started heading back out of the nursery to go out on her daily patrol. “Maybe when I get back, I’ll consider changing that poopy diaper of yours. Unless you leak of course, then you’ll just get another one on top of that as punishment.” She continued in a sing song voice as she walked out of the room, closing the door behind her without even giving Midnight a chance to get a word in.

Left to wallow in her own filth, Nemuri slumps her shoulders and huffs before getting on all fours to crawl around in hopes of finding another pacifier. Thankfully, her mommy was generous enough to have gotten a plethora of them, so it wasn’t too hard to find another rubber soother to replace the old one with.

Once the new soother was placed in her mouth, Nemuri started suckling once again and crawled around the playpen in search of something new to do. After wandering around in circles for a few minutes, Nemuri figured that the toy chest would be a good place to start. It was fun just crawling around aimlessly, but the feeling of her mess swaying back and forth as she did so wasn’t the most pleasant feeling in the world. At least when she found something else to take her mind off of it, she could sit down and sink into the putrid goop once and then not have to worry about it again until the next time she got up.

At the box once again, Midnight got on her knees and started digging around to find a toy, this time just grabbing the first thing that really gets her attention. Luckily, the older woman didn’t have to look too long, for at the very top was a stackable ring set that her mommy had recently bought her. There haven’t been many times where she had played with it, so Nemuri thought that today she’d have some fun with it.

Although, the black-haired woman wasn’t too sure how long her mommy was going to be gone for, so rather than putting all of her eggs in one basket with one toy, Midnight went ahead and grabbed a box that was filled with a plethora of different blocks, all of which she could use to construct some towers or other buildings if she so desired to later. In fact, just thinking about all she could do gave her an idea on how to integrate it with the stackable rings.

Wanting to get to that as soon as possible, Nemuri sat the items on the ground and began pushing them over towards the stuffed animals so that she would have a cozy place to sit while she played. The open area seemed a little more inviting at first, but the plushies gave Midnight an extra sense of security. Plus, some of them could act as townsfolk in her pretend city that she may or may not being making later.

When she was finally back over with the stuffed animals, the older woman carefully positioned her butt before sitting down, making sure the mess inside of her diapers didn’t accidentally crawl out the back and get on her plushies. Once she was settled, Midnight pulled the stackable rings in between her legs and set the box of blocks next to her.

From there, the older woman played to her hearts content, stacking the rings in a multitude of different combinations until she found a design that really captured what she was going for. After that, she started getting all the blocks out of the blocks so she could construct the area around it, the rings serving as the center piece for the whole thing.

With the town complete, all that was left was to fill it with life, Nemuri reaching back behind her and grabbing some of the smaller stuffed animals to place all around the basic structures that encircled the colorful toy in the center. When she was finished, the older woman looked down at her craft and smiled before reaching down for some of the new citizens of her new town to have some real fun.

A few hours passed and Midnight had totally exhausted herself. While she was in the middle of her intense play session, the diapered woman found herself drifting further and further away until she was knocked out completely.
When Mt. Lady returned from her patrol, she saw her stinky baby girl blissfully sleeping against the pile of plushies with some still in her hand, the sound of a subtle suckling filling the air as the older woman instinctively suckled on the soother for comfort in dreamland.

Finding this absolutely precious, the blonde woman took out her phone and snapped a picture before carefully making her way to the sleeping sidekick, gently picking her up and cradling the padded woman in her arms before making her way over to the crib.

“Looks like someone had a busier day than me. Sweet dreams my cute little stinker.” Mt. Lady commented as she placed Midnight in the crib, tucking the older woman in with her smelly diapers before giving her baby girl a soft kiss goodnight.
