Mix-up has recently joined OwOHub, posting his drawings there, mostly consisting of sailor horses wearing diapers. That wasn't all he was into, though, as he also animated a pony getting coated by a pink goo, turning into a rubber gasmasked drone in the process, as well as a musky pony made out of socks. His drawings generally do get a bunch of favourites, but none of that was able to make up for the emptiness of life.

Outside of the digital world, Mix-up isn't as tolerated. The mask of arrogance he puts on hasn't fooled anyone, as people continue to bash him for the diapers he occasionally wears, and others go out of their way to avoid his presence. Mix-up has lost many of his friends whenever people eventually find out about his diapers, and his OwOHub page. Even before the UGV pandemic hit like a shot from a sniper rifle, or like a boom from a Vine, he felt like he had no one left. All he could do was sit in front of his computer, the only thing that gave him something to do in life.

He checked OwOHub again, and received a notification. Someone named 'koita1234' favourited his changeling drone transformation animation. Out of curiosity, he checked Koita's account.

The bio read:

'helo i am koita, femboi minikaiju

accepting trades too uwu'

Damn. Mix-up did not expect to see someone who shares more kinks with him than just diapers. Mix-up had to check out this guy's work. Koita took photos of himself in various full suits, all of them covering his body from head to toe. Even if some of them do appear to show some fur or skin, on closer inspection, they were actually still just another part of the same suit. Mix-up was impressed. He couldn't even see Koita's real eyes in any of his suits. Some of his suits didn't even match the same shape or form, with some appearing indistinguishable from real pool toys, real plushies, or real giant rubber figurines. This guy could be hidden inside any inanimate object and Mix-up wouldn't even notice until the object starts moving. While this would be enough to cause paranoia to some, Mix-up thought it was not only cute, but sexy.

Some of Koita's various suits feel like creative ways to make bondage appear seamless. His suits also had the mysterious appeal that would make many curious. Plus, even though a lot of people are into socks, there still isn't enough sockcritter, stockingcritter, or socksuit content. Plus, nobody seemed to turn underwear into full suits, nobody except for Koita, that is.

Not only was Koita a suiter, he was also a writer. He never wrote entire novels, but he wrote short stories, usually involving suiting, but he also did transformation stories as well. He even created an entire open species based on underwear, called underwearcritters. This species has no mouth or organs, sock-like feet, mitt-like hands, are entirely made out of underwear cotton fabric, are autotrophic and capable of photosynthesis with adequate water, have a permanent underwear on their crotches that cannot be taken off, cannot get pregnant, have to rely on transforming others to 'reproduce', and they cannot ejaculate actual sperm unless sperm touches their body, which lets them become a fountain of cum, regardless of their actual sex, and the cum transforms others into underwearcritters upon contact.

After favouriting Koita's underwearcritter transformation story, Mix-up left a comment:

'Woah, this is really awesome. I would be so up for a trade if you want.'

Unexpectedly, Koita immediately replied back:

'yeah me too. hit me up when youre ready uwu'

Mix-up wasn't sure if he was ready to trade. He didn't know what exactly he wanted, and he didn't know what he was willing to do for Koita. There was so much he was into that he didn't know what to choose for the trade.

Perhaps it would be nice to read about himself being transformed into a sockcritter, but it would also be awesome to read about himself transforming into a diapercritter, but there's no denying that he would like to help contribute to the growth of underwearcritter stories either.

After some consideration, Mix-up mustered the courage to send a note to Koita on OwOHub:

'I would like to talk with you about a trade using Dmod.

:whatever:

Here's my Dmod tag.'

Mix-up then closed his browser window and opened Dmod, waiting for a private message while reading posts on art servers, looking at cool cute art, and getting chewed out by other Dmod users for his arrogance.

And then Koita sent a private message:

[koita1234] so what trade would you like?

[Mix-up] I would like to be tfed into a sockcritter/diapercritter/underwearcritter by you.

[koita1234] oh awesome. i can do that for you

[Mix-up] Okay, just one question: are you familiar with talking ponies?

[koita1234] ive never seen a horse talk. why?

[Mix-up] Well, I am a talking horse.

[koita1234] in real life?

[Mix-up] Eeyup.

[koita1234] oh ok

Koita's never seen a horse talk, but now he believes that Mix-up is a talking horse? That's quite the adjustment.

[Mix-up] So, how will we meet?

[koita1234] heres my address

Wait, Koita thought Mix-up was talking about real life? How does he think Mix-up is going to be able to actually TF into a sockcritter, diapercritter, or underwearcritter in real life? Aren't they all fictional species? There's no way real life could be that sexy, right?

Perhaps Koita thought Mix-up was talking about suiting. That's the only way this could all make sense. Still, the curiousity was flowing through Mix-up's veins, and he also desperately wanted to try out one of Koita's suits anyway, so either way, Mix-up saw it as a win-win.

[Mix-up] So, what do you want me to draw for you?

[koita1234] you can draw without fingers?

[Mix-up] It just takes a bit of practise...

[koita1234] i dont know what exactly i want.

[Mix-up] Perhaps you in your sockcritter, diapercritter, or underwearcritter form hugging, kissing, and groping me while I'm tfed into a sockcritter?

[koita1234] oh yess i would like that please

[Mix-up] They say a picture is worth a thousand words, but a drawing is worth 3000. Or 4000 with a background.

[koita1234] oh?

[Mix-up] Yeah, so after you're done making me your little sockcritter/diapercritter/underwearcritter pony, it would be nice to receive an experience worth 3000-4000 words.

[koita1234] i will give you even better

[Mix-up] I knew you could, sock monster.

[koita1234] uwu

That was a pretty amazing conversation. How did this day go from 0 to 100 really quickly? At this point, Mix-up couldn't wait to go meet up with Koita and see what he actually looks like.

Due to the UGV pandemic, Mix-up has to put on special gear to protect himself from getting infected, and protect others from being infected, too. Mix-up opened his drawer (not to be confused with himself, as many people tend to do when complimenting his drawings), full of diapers. Mix then pulled the diapers over his pelvis, ensuring that the diapers were at a comfortable position before dropping himself back down to all fours.

Mix closed his drawer and opened his closet, surprisingly full of suits fitted for a 4-legged horse his size. Mix grabbed 2: his socksuit, and his red hazmat drone suit. He threw them on his bed, and then went to the bathroom to grab some wipes before heading back to his bed. Mix laid down, cleaning his feet one-by-one with the wipe, to minimise all the dust that gets on his feet.

Mix then laid his socksuit down on his bed, the front side facing up, which was where the entry slit was. Mix laid himself down in front of the suit, putting his 4 legs through the slit into the suit's own legs. Mix then put his head through the slit into the suit's head, adjusting it to ensure his face fits properly. Mix then put his tail and put it inside the suit's tail.

Now that the suit's slit is in front of his body, it was time to sew it shut. Mix took a sewing needle and some string out of his nightstand. He grabbed the string and pulled it through the thread, pulling out twice as much as he thinks he needs. Then, he tied both ends of the string together, making a knot. He then cut near the knot, having the knot mark the end. Then, Mix pierced the needle through the suit, and pierced again, making tiny zigzag stitches to ensure the suit doesn't break open. After sewing the entry hole shut, he made another knot with the needle, and tightened the stitch, ensuring it's not too lose or too tight.

After sewing himself inside of the socksuit, Mix then laid out his red hazmat suit in the same fashion he did with his socksuit. Mix then unzipped the suit from the front, starting off by inserting his legs into the suit's. For each leg, Mix had to pull the suit up to ensure the leg fits comfortably, since Mix's suit is meant to be form-fitting. Mix then inserted his tail into the suit's, just like he did with the socksuit he is currently wearing. Finally, Mix put his head into his suit's, adjusted it, and zipped the hazmat suit shut.

Mix could hear his own breath inside the gasmask of the hazmat suit, every muffled inhale and exhale enough to turn him on. Mix walked out of the almost-in-disrepair house, holding his keys in the pocket of his hazmat suit. With every step, Mix-up had to resist the urge to orgasm in public from the big poofy diaper shuffling in between his hind legs, itself producing a visible bulge in the suit that everyone could see. The weather was actually unusually warm for early spring, which made Mix-up, wearing 2 suits at once, sweat even more. This was something Mix desired, the sweat and musk serving as an appetiser for the encounter with the mysterious Koita.

Mix ran through the bike lanes of the streets, following the directions he folded into his other hazmat suit pocket. Horses have always been allowed to walk on the street, as a leftover from history. The catch is that miniature horses have to use bike lanes due to their incredibly small size.

Once he verified the address, Mix was in front of a broken and beat up apartment building, similar to his own house. He rang the doorbell corresponding to Koita's apartment, and spoke through the fabric of his socksuit, and through the filters of his gasmask.

'It's me, the one and only Mix-up, here for the experience.' said Mix.

Mix then heard the sound of a window opening, echoing against the walls of the other buildings surrounding them. He looked up, and staring back at him was a strange purple creature, with long floppy ears dangling at the sides of the head, long eyelashes, 2 fangs sticking out of the mouth, and what appeared to be arms with no hands at the end. Or could it be front legs? Mix was uncomfortable with the way the creature seemed to stare at him, but could not understand why.

As soon as the creature went back into the window, the door buzzed. Mix pushed it open, and went inside.

It was not the right time to wonder about a purple stranger, the species of which he has never seen before in real life. Now that he thinks of it, could that be... Koita in another one of his suits? The creature did resemble the design of one of them, but Mix-up was really sure what he saw was made of flesh and blood.

It was pretty difficult to walk up the stairs, as they were a bit thin for Mix-up's thick hooves. After a long way up, Mix was in front of Koita's address. With no hesitation, Mix pushed the doorbell with his muzzle.

The door opened, revealing the same purple bipedal creature that was staring at him. And as Mix suspected, this creature was pure flesh and blood, with no feet on the legs either, and a vaguely feminine body shape where the hips were a bit wider than the torso. The creature's arms were indeed very thin, too, contrasting with the thick legs. In between those legs was all it took for Mix to know that despite the overall feminine appearance, this creature is a male.

'henlo' said the strange purple guy, with his signature creepy stare. Did Koita send the wrong address? Who is this guy, and why did Koita base one of his suits off of him? The purple being then seemed to recognise him.

'u must be mixup, that guy on owohub and dmod' exposited the purple man.

'Do you know where Koita is?' responded the confused equine.

'he is me'

This is Koita? That must mean he based a suit off of his own body, not that anyone would know it was his real body.

'perhaps this will convince you. uwu!!!' Koita put his arms on the sides of his head and tilted his body to his left, replicating one of the poses from his photos.

'How do you craft those suits with no fingers?' asked Mix.

'It just takes a bit of practise...' replied Koita, blushing. 'anyways come in'

Mix came in with Koita. Mix unzipped his hazmat suit, revealing his beautiful hoof-sewn work of art and socks.

'wow that is so cute did you make it urself?' praised Koita, petting Mix.

'Yes, nuzzle the socksuit. You may touch all of the masterpiece.' replied Mix.

Koita put the stub on his arm on Mix's diaper, rubbing the soft padding on Mix's arse.

'How can you turn this perfection into an underwearcritter?' joked Mix.

'simple i have a special pair of underwear that will activate when worn and integrate with anything.' explained Koita, unaware Mix was joking. All Mix could do was stare, as he followed Koita and his thick arse to his room.

Koita's room had a lot of dressers and drawers, a pump for inflatables, boxes of foam, a giant dummy that matched Koita's size and shape made out of duct tape, brushes, latex paint, a sewing machine, sheets of several different fabrics... and no bed. There were, however, piles of dirty discarded clothes on the floor, with a 'sheet' of socks also on the floor. There was also a thick, old laptop connected to a power outlet, with an ethernet cable as well.

'u can lay on the bed while I get my gear ready ;3' uttered Koita. Mix did so, waiting to see what Koita would be wearing.

Mix heard Koita's dresser being opened. The audible crinkle of a diaper soon followed. Mix could then hear a small smack on the floor, like a piece of clothing hitting it. Mix's curiousity kept him on edge, but he didn't want to spoil half of the experience. More crinkling followed, as well as the sound of tapes being pulled up. After, some snaps were heard, like the kind that happens when you put on something tight. Then Mix could hear tapes being applied again.

Mix saw 2 shiny crinkly legs walking over to him. As they turned towards him, it was apparent that they were purple on the outer sides, and grey on the inner sides, separated by a while outline. Mix looked up to see a seamless diaper with tapes in the front, matching the same colouration as the legs, except only the front was grey. The torso also followed the same colouration, being made of the same material, and even having more tapes around the white lines dividing the front from the sides. The arms are also purple, the sides facing Koita's body coloured grey and also separated by white lines. The head matched the colouration as the rest of Koita's diapersuit, almost completely purple except for the snout, which was grey, connecting with the grey on his front body. The suit's face lacked any facial features: no eyes, no mouth, nothing to breathe out of.

Koita laid down on the socksheet with Mix.

'i can see that you have been pretty patient for me' observed the featureless diapercritter Koita. 'have this'

Koita gave out a pair of underwear.

'this underwear has the ability to fuse anything you have on into your body. be warned: once you put it on, you can't take it off, though other similar special pairs of underwear can overwrite this one' explained Koita.

Does Mix-up really want to mix up his life forever? In Koita's stories, underwearcritters can't eat, but rather get their food from the sun, and absorb water through their featureless skin. They also do not ejaculate sperm, though they can still have dry, clean orgasms. If Koita's stories had some basis on reality, then a single underwear really can change Mix-up's life.

blooooort

'ah, I can still smell my own waste products.' remarked Koita, who had just shitted in his nappysuit.

pbrrrrrrt

Mix-up took a shit in his diaper, too, enjoying the feel of his own waste products.

'I will always accept perfection.' remarked Mix-up, as he put the black underwear on over his diaper. The underwear initially squished Mix-up's diaper, revealing that he was as hung as a horse right now, but then immediately grew to cover the whole diaper, leaving an underwear with a giant diaper bulge inside. Mix-up's socksuit also began to change colour and pattern. What was initially grey with hints of red became primarily blue, with white areas on the legs nearing the hooves. The socksuit's tail also began to match the exact colouring of Mix-up's, and so was its face, though it still lacked Mix-up's eyes, nostrils, and mouth. Mix-up's socksuit also began to grow hair coloured identically to his own, though instead of being made of socks like the rest of his body, it was made out of underwear.

'woah this is amazing!' shouted Koita. 'i wonder if the sperm thing works too'

'Go ahead. Try it if you want to share my perfection.' invited Mix-up.

Koita rubbed his arm on his diaper, hoping to release new sperm. It was coming, but it was not far up into the queue yet. Koita flipped face down, grinding his diaper against the floor. Koita climaxed.

Koita quickly undid his tapes and made sure to aim the sperm onto Mix-up. He shot lots of sperm and Mix-up absorbed it. Mix-up could feel the sperm travel through his body. It was multiplying, too...

Mix-up felt like his entire body was filling up with life. On Mix-up's diaper crotch grew a giant bulge, ready to release all the sperm out like a hose. Koita had taped himself up again, but that didn't matter, because Mix-up's cum still landed on Koita. It was like Koita was being entirely coated in cum, like it was flowing through every spot, through all the fabrics' pores.

Koita was too wrapped up in erotic pleasure to notice any weird feelings he is currently experiencing from his body. His internal flesh and bones melted away, leaving only faeces and urine inside, while his skin fused with the diapersuit. All Koita could tell was that he now felt much more sensitive, not realising that the diapersuit is now his entire body.

There were also visible changes happening to Koita. His diaper was changing colour, from being split between purple and grey, to pure black, with an elastic underwear waistband forming. Koita's tail was also changing, growing longer, and changing pattern to resemble... Mix-up's?

The purple of Koita's crinkly skin became blue, with white areas around the tips of his arms and legs, just like Mix-up's, though the grey parts stayed as-is. Koita also grew hair matching Mix-up's, also made of cotton too. Koita's legs started to grow hooves, thickening up even further. However, what neither Mix-up nor Koita would be able to predict was what would happen to Koita's hands.

Instead of becoming hooves, Koita's hands started to grow fingers, similar in shape to that of a human's. Unlike the underwearcritters Koita wrote about before, Koita's new fingers are completely separate and independent.

With his new crinkly hands, Koita put them on Mix-up's head, holding his head as Koita started to nuzzle him.

'ur right this is perfection!' shouted Koita.

Mix-up nuzzled Koita back. Koita and Mix-up began to hug each other, Koita's new hands gently caressing Mix-up's back and underwear diaper arse. Mix-up started to use his front legs to do the same to Koita's underwear diaper arse. Koita and Mix-up's arses were sensitive to touch, enough to cause them to come close to another orgasm. And then Koita's diaper started to have a growing bulge similar to Mix-up's.

Koita started hosing huge amounts of cum into Mix-up, the loads coming through Koita's underwear diaper. Mix-up's cotton skin absorbed it all up, but Koita's cum now had strange properties to it, too.

Mix-up began to feel that something was changing. Mix-up's structure was being rebuilt, the front legs restructuring into arms, the torso flattening, the legs growing as tall as Mix-up's torso, the neck changing position from the top of the torso to its front, and yes, Mix-up's new arms developed hands with independent fingers.

Not only did Mix-up have a different structure now, his pattern was changing too. Mix-up started to form dark grey areas identical to Koita's.

Mix-up did not expect a transformation as major as this to happen to him. Mix-up stood up on 2 legs, feeling like he's high up on a shelf due to the higher view he has. As Koita stood up, Mix-up now noticed that he was quite a bit taller than Koita. Mix-up quickly embraced Koita and squeezed with joy at the new change. Koita hugged him back.

Through his blank, mouthless face, Mix-up had a message for Koita.

'Thank you for everything! X3 The fingers, the underwearcritter form, and this whole night together!'

'night?' asked Koita, before turning his head to look at the window. The sky was a very dim blue, the orange street lights the only thing making the roads visible.

'Well, it's dark out. I have got to go home, good night! uwu' exclaimed Mix-up, beginning to pick up on Koita's habits before leaving.

Koita locked the door, unable to forget the night that had just happened. Koita looked into the mirror in his bedroom, the new changes making him already miss Mix-up. Koita opened the toilet and was about to step out of his suit, but as he was pouring all of his waste into the toilet from his insides, he was surprised to find out there was no body inside. Koita then went into the bathtub, started up the water, and washed himself, remembering to put soap inside of his underdiapercritter body.

After a lengthy drying process, Koita then went back to socksheet, rubbing his permanently fused sensitive underwear diaper crotch against it.

---

Mix-up was no longer as fast as he used to be, his anthropomorphic structure now making him bound to the sidewalks, but ever since he grew fingers, his drawing skill has greatly improved. Mix-up's new fingers also allowed him to practise typing faster, as well as making it easier for him to sew.

Mix-up no longer had to pay for food, all he needed now was sunlight, water, and some dirt to roll around. Ever since that night, Mix-up also no longer had to use the bathroom. It was also much more common for Mix-up to stroke himself, since his orgasms are now completely dry, and his cooldown period is much shorter as well.

He has only a single purple femboy minikaiju to thank for this...

[koita1234] uwu ur welcome any time
