Katsuki was never the most well behaved person at the best of times, this was a fact that his loving boyfriend and daddy dom Eijiro both knew and accepted.
But even he was taken back as after being woken up at 5 am sharp Christmas morning so they could open up presents, Just how much of a pain in the ass and whiny Katsuki could get with a combination of a lack of sleep and munching on sugary treats.
The only thing that had so fair saved Katsuki from getting a spanking of a life time and having his mouth washed out so much he'd be blowing bubbles until new years day was the fact that A: Eijiro took into account it had taken Katsuki until 1 am to fall asleep in the first place and B: the little guy was just SO adorable in his candy cane print thick diaper and sleeves green top with frosty the snowman on the front. Even then though, the little cutie pie was pushing it, such as his little stunt while Eijiro had been making lunch.
Being called away from the kitchen with a cry of 'Daddy I drew you a picture!' Eijiro was greeted by a poopie smell, not that he wasn't used to that with his boyfriend crapping himself more often then not.. but then froze as he saw brown smeared on the wall and brown all over Katsuki's hand.
"..You didn't!?!" Eijiro gasped, in shock and disgust.
"Whattt don't you like my pretty picture?" Katsuki asked then pointed at the house and the stick figures. "That's our place..and that's you.. this is mean.."
Pausing Katsuki went to slip his finger in his mouth, and got a loud gag of disgust from Eijiro who rushed over to grab his wrist.
"Katsuki! stop what d-" he started to ask, but Katsuki burst out laughing.
"it's just chocolate ya dork! did you really think I'd play with my own soft serve?!" Katsuki cackled.
Lifting his butt up, Katsuki showed Eijiro that small chocolate balls he'd sat on, with some wrapping paper under his butt to make the 'paint and smirked.
"Oh man, the look on your face! I can't even do it justice!" Katsuki giggled and snorted, then caught a look at Eijiro's face and all the mirth dropped from his.
"..Soo I'm thinking maybe that joke wasn't as funny as I thought, and after Lunch I should take a nice long nap." Katsuki said quickly.
"Read my mind!" Eijiro said, between gritted teeth, then lead Katsuki off to go and get washed up.
The prank was useful in one way: Eijiro had been on the fence about letting a certain cat out of the bag for awhile, but hadn't been able to make up his mind as he didn't wanna humiliate his widdle baby boyfriend.
Despite what Eijiro told him and Katsuki's own arrogance told him.. the blonds babyish habits and choice of undies and lifestyle had outed him to more then a few of their friends, who got the rest of the details from Eijiro in exchange for keeping up the lie that they didn't know so Katsuki wouldn't freak out.
The blond barely could handle the humiliation and embarrassment that Eijiro could dish out once he got going, and though his body showed how much he loved it, Katsuki's mind was stuck in toddler land for hours after a good little humiliation session (Usually ended with Katsuki going 'goo goo gaga' hands free.)
But act like a brat and get punished like one was Eijiro's motto for dealing with this, and he started to call up the friends who'd be coming over for a little Christmas party later.. telling them to bring the special gifts for Katsuki that he'd helped them get.
it would only be Izuku, Denki and Momo.. but Eijiro had a feeling that that's all it would take to have Katsuki in baby land till new years, if not a little longer.
'Heh, that would actually work out..we won't have to have a fight over who's the new years baby!' Eijiro thought and snickered.
in the middle of a dream where the stupid red nosed fucktard hadn't shown up so it was Katsuki in his diapers and reindeer sleeper stuck leading the sled for Santa.. The Blond whined and tried to swat away the hand gently shaking his back.
"heh, come on little guy..time to get up." Came Eijiro's voice, though Katsuki kept his eyes closed.
"No get up! sleep!" Katsuki grumbled, reaching around and snagging a large teddy bear and pulling it over his head.
"yes get up. come on little man." Eijiro said, easily taking the teddy and tossing it to the foot of Katsuki's toddler style race car bed.
"Five more minutes!" Katsuki tried.
"you've already said that twice.. if let you sleep in anymore there won't be time to change your diaper before the party." Eijiro said with a snort.
"Bah! I'm clean.." Katsuki grumble, then reached down, patting his butt and front to double check. "Yeah! so it's good." he grumbled.
"Alright but I did warn you..Five more minutes." Eijiro said, clearly delighted.
letting Katsuki drift back off to sleep, he wondered if he should of pointed out that meant no changing into one of his thinner daytime diapers, but then shrugged. that seemed more like a sleepy brat Katsuki problem, not his.
7 minutes later it was a whinny yawning Katsuki who was dressed in long sleeve shirt, red with Santa and some elf's on it and a pair of light grey sweats, his crotch and butt puffed out and the top of the diaper poking out, not that the sleepy blond seemed to notice or care as he gave half hearted waves to everyone as they showed up, nuzzling into Eijiro and trying to sneak back asleep though Eijiro was a step ahead of him.
Silently the four adults agreed to not say anything about Katsuki's clearly padded state till the blond noticed it himself, instead just making small talk as they gathered around the living room to chat and catch up.
Izuku, Momo and Denki had gone on to become full on hero's while Eijiro and Katsuki had opted for the private sector, renting themselves out as super powered bodyguards as needed though it was all on the level, but naturally the three hero's had the more exciting stories to tell.
Not that they were keeping Katsuki from trying to sneak off and get a few more minutes of sleep in, playing it off as he was just cuddling Eijiro. The redhead was wise to the trick however and sat Katsuki up with a smirk.
"I think I better go get someone a coffee or he's never gonna wake up." Eijiro said and wagged his eyebrows.
"oh, I didn't think Katsuki drank coffee." Momo giggled, sipping a tea. "Bad for little guys and all that.." She added with a wink.
case in point, Katsuki DIDN'T like coffee and never drank the stuff if he could help it. He would just get hot chocolate and play it off as coffee instead.
However hearing Momo's comment the diapered brat went wildly on the defensive.
"What!?! Of course I drink coffee! I drink like 2 pots a day! how do you think i stay awake and aware when working long hours?!? I'm a legend at coffee shops around here..or I was till they're coffee was so weak i started to make my own!" he ranted and huffed, snarling and wiggling around in his seat, clearly unaware how much he was crinkling as he did so and the others were biting the insides of their cheeks trying desperately not to burst out laughing.
"in fact, I make a pot of coffee, then use that coffee as the water to make anther pot, then use THAT coffee t-" Katsuki was saying, when Eijiro reached over and pinched Katsuki's lips shut with a expression that made it clear this wasn't the first time he'd had to shut the blond up this way, and he doubted it would be the last.
"Let me sum it up for all of you. he drinks coffee." Eijiro said, then let Katsuki's lips go as the blond glared at him. "Be good while I go and get your drink..failing at that, try to be less bad then normal."
"Hey!" Katsuki huffed and glared as Eijiro got up and walked away. "I can be good!"
"Really? I'll believe it when i see it." Izuku commented, taking a bite out of a Christmas cookie and smirking as Katsuki locked onto him with a death glare.
"Careful, if you attack him you prove him right." Denki warned.
Katsuki growled and crossed his arms, but managed to keep from attacking anyone as he muttered and grumbled away, making the guests laugh.
Getting in the kitchen, Eijiro decided since Katsuki was gonna put up such a epic fuss over him being a 'coffee drinker' that it would be indeed Coffee Katsuki got.
of course he knew this would backfire in a way on him since the little guy would be amped and wired for sound but figured it would be worth it as he got the brat 4 sugar and chocolate milk instead of white milk for the cup of Joe, slipping in some 'fart powder' as Katsuki called, it, though it was really fiber powder.
'not that he needs help pooting up a storm.' Eijiro thought with a smirk, coming back out.
Katsuki had the trey of Christmas cookies in his lap and was blowing a raspberry at the others as he walked back in and he paused.
"..Katsuki do you really wanna explain whats going on or do you wanna put the cookies back?" He asked.
"Um.. is that a trick question?" Katsuki asked.
"Put the cookies back or I'm taking back your game system extreme 6." Eijiro said, setting the coffee down and winking at the others.
"you wouldn't!" Katsuki said, a look of panic coming over his face and a muffled poot coming out.
"Try me little man." Eijiro said and held his hands open for the cookie tray.
"..I'm giving you the cookies because I don't want you to look bad in front of the others." Katsuki said, handing them over quick and picking up his mug, blushing.
"Mmmmhmm and I thank you for that." Eijiro said with a roll of his eyes as he set them back down on the coffee table and then took his seat.
Katsuki stuck his tongue out one last time when went to take a chug of what he assumed would be hot chocolate..and then his eyes bugged out and he gagged for a second, barely managing to swallow the coffee down as everyone looked at him.
"heh, what's wrong?" Denki asked.
"Yeah buddy, what's wrong?" Eijiro asked, snagging cookie and munching on it as Katsuki glared at him.
"I,...you.." Katsuki growled.
"Gee, if I didn't know better..I'd almost say Katsuki doesn't like coffee..but that can't be after how much you were boosting about the coffee you drink earlier." Momo said.
"unless of course..you were lying." Izuku added.
Katsuki huffed and glared at them all.
a honest brat would of admitted the truth. a smart brat would of claimed it was too weak and offer to go and make his own. But Katsuki.. took a big long drink, trying to just get it over with and prove what a big boy he was, even as coffee leaked down the sides of his mouth and dribbled down his chin.
"awww, somebody needs a bib! here, let me handle that." Momo said and used her quirk to make a white one with a blue trim and 'daddies little stinker' written in baby blocks on the front, then handing it over to Eijiro.
"awww look buddy! Momo made you a extra present!" Eijiro gushed as Katsuki pulled the mug away from his face, making faces and trying not to gag. "What do we say?"
"..I couldn't possibly accept that and whatever awesome gift you already brought me so I'm sorry but I'll have to refuse it because I only have one gift for you." Katsuki said, talking normally and then his speech speeding up as he started to bounce a little.
"Nonsense! I Insist that you accept it! you'll just get me two presents on my birthday ok?" She said and then snickered as it was clear to everyone that the sugar and caffeine was hitting Katsuki's system like a ton of bricks.
"No no no no nonononononononononono!" Katsuki said, sounding as if he was going on hyper speed but alas, even though he waved his arms around (having thankfully set his drink down) the bib was tied on nice and tight around his neck. "Ugh! Bib's are for babies and I'ma big boy!"
"oh of course. Totally a big boy." Izuku said, winking over to Denki, who snickered and smirked.
"Why don't you just sit back and relax and enjoy your cup of Joe. Once your finished we'll open up the rest of the presents." Eijiro chuckled then mentally added. 'Of course by then you'll likely be MAKING presents but ah well..'
Such was the price you paid for having a total big baby brat and dork for a boyfriend.
Feeling like his body was filled with energy, Katsuki couldn't sit still and was crinkling up a storm as he wiggled his butt around, slowly working the back of the jogging pants down as he did so, not that he could tell.
with the last of the god awful coffee in him, he scooted onto the floor and slid over to the Christmas tree, to snag the other's presents, not aware that his white diaper butt was semi on display as he wiggled it looking over the gifts and then smirking impishly.
"Momo gets her present first as a thank you fer the bib!" he declared, still wearing it and tossing it over to her.
"Awww, And here I thought I'd be first." Izuku said smirking.
"NOPE~ you git ta go last!" Katsuki coo'ed, then with a evil grin added. "Heck, Maybe you don't even HAVE a pres-"
"Katsuki, you know I still have the receipts to your gifts and CAN return them." Eijiro said, cutting the brat off before he dug himself in too deep.
"You wouldn't!!" Katsuki gasped, and a muffled fart was heard, getting laughs from everyone even as the bratty blond blushed. "Oh grow up, it's just a fart!" He huffed.
"I think I better take over handing out the gifts. why don't you go and sit and behave like a good boy." Eijiro said, coming over and disarming Katsuki's retort before it could leave his mouth with a head pat and hair ruffle.
Huffing and acting like he was doing EVERYONE a huge favor, Katsuki scooted his way across the hardwood floor on his shins and knees using his hands and climbed back up onto the couch.
"Let's do everything YOU wanna do!" He huffed.
"Glad you see it my way." Eijiro said and winked.
with the adult gifts handed out (Momo getting a new MP3 player, Denki getting a box of trading card from a series he was into as a kid and Izuku getting a baseball cap that was signed by every big name hero the duo could find) it was time for the happy couple to get their gifts.
Eijiro's just got a gift from all three in one go, a gift card for a local shop and he gushed over how handy it would come in with getting things for the house.
Katsuki had blushed and squirmed, since the shop in question was where they got his diapers from and Eijiro had been commenting about just how fast Katsuki seemed to go though them.
'but..there's no way those two things are related. you're sooo not busted. your a ninja! a diaper ninja!' Katsuki thought to himself, and was picturing himself in a Naruto type setting and throwing ninja stars when Eijiro snapped his fingers next to his face, Making Katsuki jump and wet himself.
"Jesus!!! Are you trying to give me a heart attack!?!" He yelped and glared, puffing out his cheeks.
"Well I tried saying your name 5 times but you were off in la la land." Eijiro said. "I figured you MIGHT wanna be paying attention when you opened up your gifts..but hey, I'm silly like that."
"...Smart ass." Katsuki muttered under his breath.
"what was that?"
"Nothing! Oh, I better not keep everyone waiting!" Katsuki said quickly, sweat dropping and snatching the nearest present and ripping it open, barley noting that it was from Denki.
whatever he had been expecting as he tore the paper away from the large present, it wasn't the night time lullaby player that boasted about how easy it was to hook onto a baby's crib or even a toddler bed..and how it played 5 different lullaby's.
"Oh wow, look at that little guy! No more fussing and trying to get to sleep at night for you anymore!" Eijiro coo'ed and smirked, patting Katsuki's head as the blond brat's mouth hung open in shock, some drool leaking out and going onto his bib.
"I..I.." Katsuki stammered and then shook his head. "I don't need this! this is for babies!" He said hotly.
"That's bratty baby for thank you Denki." Eijiro said and smirked, as Katsuki stood up and turned to face Eijiro.
"You hush! I'm NOT a bratty baby I'm a-" Katsuki was interrupted as Izuku leaned over and with one swift motion, tugged the pants down around Katsuki's ankles. "Big..big.."
"A big baby?" Izuku suggested, getting chuckles from the the others. "Relax Katsuki, we all know your Eijiro's widdle guy. it's frankly super cute." the green haired hero said and sat back in his seat.
"I..But..nooo! See I hid it so well an-" Katsuki started to say, but it was Momo who cut him off.
"Everyone's known for awhile. you really don't do a good job of hiding it. but like Izuku said, it's alright, it's cute. now be a good boy and sit down and open your next present." She said.
At lost of what to say or do, Katsuki nodded dumbly and took a seat, then as a after thought kicked his pants off from around his ankles.
"Uh-oh, Looks like he's soaked, Do you need to change him?" Denki asked, more out of legit concern then teasing.
Katsuki was too stunned to react or say anything, and the question wasn't addressed to him anyhow. It was Eijiro who asked a, but not before sticking a finger in the leg band of the diaper..a act that had Katsuki sucking on his thumb.
"Nah, he'll be fine. he's flooded them way worse then this before, right little guy?" Eijiro said/asked, then reached up and gently tugged Katsuki's thumb out of his mouth. "Ah ah ah, we've talked about this buddy..whats the rule?"
"N-No thumbs..in mouth..cuz..cuz little boys thumbs have lots of germs.. and..and.." Katsuki said in a slow almost toddler like state.
"Holy crap..did we break him?" Momo asked, raising a eyebrow.
"Nah, he's coming down from the caffeine and when he's super embarrassed he gets like this." Eijiro said, tugging Katsuki in close to him, and giving him a one armed hug. "we might have to just put him to bed though. He'll open your gifts later guys, we don't wanna push him too much further when he's like this or he'll go total baby for a good day or so and we're suppose to visit Mitsuki tomorrow."
"awww ok. well let me know how he likes his T-E-D-D-Y B-E-A-R." Izuku said, reasonably sure that Katsuki could spell at the moment.
"Heh, and if he likes his new S-L-E-E-P-E-R from me." Momo said, getting into the game.
Katsuki felt like he should argue that he could spell, that he knew what the gifts were.. but truthfully he was having a hard time figuring it out at the moment and just nuzzled into daddy, feeling small but safe and warm all over..then a lot warmer around his butt.
"Heh, I guess Katsuki wanted to give you all one last present before he went night night!" Eijiro said. or at least that's what Katsuki thought he said, he was too busy going back to sleepy land to care.
The end.
