A little (jealous)

Summary:

Bakugou is a little and the whole Bakusquad are his carers. He’s used to being the center of attention because of that but what will happen when a certain redhead says he wants to try it as well?

Surely nothing bad could happen! Right?…

Notes:

I had this sitting in my notes for such a long time now already so I thought fuck it and just started editing it and now I’m posting it. (ृʾ́꒳ʿ̀ ृ )ु
This is quite… well, it’s not as angsty as some other fics but it doesn’t have a lot of fluff as well. (Just a little disclaimer for intrusive thought)
Let’s just say Kirishima is the fluff because that boy is too pure for this world!

Enjoy!<3

(See the end of the work for more notes.)

Work Text:

Because of an… accident… the Baku squad found out that Bakugou regresses. At first everyone was extremely confused and Bakugou… well, he was panicking but after a while it all calmed down and Bakugou didn’t have one carer, he now had four! Obviously they weren’t allowed to talk about it outside of his room but hey, they were closer than ever before because of it!

They got used to the routine of Bakugou sending a short message into the group chat when he wanted to regress or was feeling himself slipping and everyone coming to his room in seconds to take care of him. It was kinda suspicious how all four of them would just randomly stop what ever they were doing and scurrying off instantly after looking at their phone. But since it was all of them no one really cared.

Bakugou got used to all of them being there. Stopped being scared or shy after a while and just started having fun while he’s regressed. He got used to having everyone fawning over him and being the center of attention. With four people being there he didn’t need to worry about anything and even though big him would never admit it, he enjoyed it quite a lot and he was way more relaxed now.

However, considering all that, he didn’t really react well when Kirishima said he wanted to try regressing as well.

Let’s just say that, at least he wasn’t screaming but he still threw something that could only be labeled as a temper tantrum. He didn’t know what came over him but he was strangely annoyed at the request from his friend. All four were his caregivers! He can’t loose that, he can’t loose his only support!
Just when Mina was rubbing a dejected looking Kirishimas arm, glaring at Bakugou, Seros mouth hanging open, brows furrowed and Denki just saying :„What the fuck dude?“, did he realize that he hurt the redhead. Of course he hurt him with that reaction but…
Maybe Kirishima really wants someone to take care of him as well?

„Guys, it’s alright… sorry, i won’t ask again… that was kinda stupid right?“, Kirishima let out a little embarrassed laugh and rubbed the back of his head but his smile trembled a bit. Fuck. God damn it…

„Are you sure?“
„Yeah, I clearly made Bakubro uncomfortable. Sorry, I won’t ask again.“, he apologetically looked at Bakugou and the blond bit the inside of his cheek.
They didn’t talk about it again, to be honest they didn’t even really talk at all after that. There were only angry glares and shaking of heads from Mina, Sero and Denki. Not even any scolding or telling Bakugou off. Probably because they knew that Bakugou knew that he fucked up. They wanted him to feel it.
And he did.

He felt it with every time Kirishima shifted and fidgeted. Every time he tugged at the hem of his own shirt when they met after the incident. Every time- fuck. He should really get his shit together. He can probably deal with loosing one carer… right? He’ll even win a playmate so it’ll be fine… right?

„Let’s do it.“, he mumbled when they were once again sitting in silence a few day after. All of them looked at Bakugou, confused. He rolled his eyes but even though he was acting so high and mighty the next sentence came out almost completely breathless „Kirishima regressing with me.“, Kirishimas eyes grew wide for a short second before he composed himself again. „It’s alright, you really don’t have to force yourself. It was a stupid request to begin with.“

„I’m not… forcing myself! I- It’s ok. I’m sorry for… the other day.“, he bit out. The other three looked at each other, doubt in their eyes. „Really?“, Kirishima lit up, completely oblivious to the weird atmosphere in the room. Bakugou nodded before slightly looking away.

Mina cleared her throat and smiled at the two „I’m so glad you changed your mind blasty! But… wouldn’t it be better to have Kirishima regress alone the first time? It’s just that we don’t know how young he’ll slip and-"
„I said it’s fine!“, Bakugou huffed.
If Kirishima regressed only with the other three around… what if they forget about Bakugou?! No… they wouldn’t. But what if Kirishima is cuter? What if he slips so young that they give him all their attention? What if they realize how annoying Bakugou is compared to another age regressor?…

Mina, Denki and Sero exchanged another look. Kirishima clapped his hands „When should we do it?“
„We can do it right now. I wanted to slip anyway!“, more doubtful looks and Bakugou is dead set on making sure they won’t be able to open their eyes ever again if he catches them doing it again. But it also encourages him to not make them regret it. He’ll do a good job at making Kirishima feel good! That can’t be difficult… he can do it. If he shows them that he’s ready to give up some of their attention maybe they won’t abandon him because the other little is cuter…

It took a while to make Bakugou slip and it took even longer to kinda, sorta make Kirishima slip, but they eventually managed to take all sense of responsibility from them and let them relax. Kirishima was very embarrassed at the beginning, always looking at Bakugou for reassurance and still being pretty tense when Mina tucked him under her chin and wrapped her arms around him. Essentially babying him. It was to be expected from someone who used the word manly not only on a daily basis but also as mantra for his life but it suddenly seemed to be a lot easier after Bakugou started to slip into the mindset of a four year old.

Having someone around that actually was regressed and basically proved to him that it was ok to let go would make everyone tempted to at least try to slip once as well. Maybe that’s the reason why Kirishima wanted to try it.

And let’s be real, the boy deserved to just be able to relax. Everyone saw how tense he seemed the last few days so they and especially Mina made it their mission to make him slip fully! They cuddled, played games and after Bakugou was little they started watching a cartoon.

That day Kirishima only fully slipped for about ten minutes, maybe even less, before he was ripped out of it again because his brain somehow thought it was necessary to connect the „nice“, Denki said with the upcoming English test he still needed to study for. But it was more than they already expected for the first time and they now knew that Kirishima fell around three to four-ish, which would be perfect since Bakugous age usually was around four plus minus depending on how stressed out or tired he was.

They decided to try again and after maybe two weeks Kirishima actually stayed in headspace and got comfortable. It would have been perfect now that they were getting into the new routine and everything seemed to be stable again… well, if only Bakugou, or better Suki, wouldn’t behave so weird. Bakugou seemed to only have agreed to this to maybe play with little Kirishima in the first place but that never really happened.

It was as if Suki was ignoring Kirishima, no Eiji. Never even talking just one word to him, which was very unusual. It was even more concerning since Eiji stuck to Suki as if he was his older brother. Always trying to show him something or copy the things he did. It got the point that all of the carers would start scolding Suki but all that achieved were pouts and glassy eyes and then the circle would continue.

The more time went on the more distant Suki grew and the more frustrated Eiji got. Finally Eiji just stopped to follow Suki at every move he did and fully concentrated on Mina as his comfort person.
Mina was giving Eiji her full attention as well and while at the beginning Sero and Denki were completely concentrating on Suki, only occasionally looking to Eiji to coo at him, their focus gradually shifted as well the more Suki pulled away.

Maybe they should have been alarmed because of it, but they just labeled it as Suki wanting to be more independent.
One particular stressful day later however it all went downhill…

Bakugou was feeling the all too familiar fuzziness creeping in while he was sitting in class. Training had been hard, fucking Deku beat him while sparring because of fucking course! The day couldn’t get fucking worse! He couldn’t concentrate on anything since he woke up, his battery is just empty. Everything just felt like too much. The light coming through the window was too bright, the extras were talking too damn loud, the chair was too hard and the stuff the teacher said was just too incoherent, the air was too stuffy, there was too much dust dancing in front of his eyes…

So when he finally got back to his dorm room, teetering on the edge of little space (he was already proud of himself that he actually managed get to his room without any incidents on the way) he pulled out his phone to type into the group chat that he was regressing but he stopped mid track when he saw that Kirishima had written something just a few seconds ago. He wrote that he’s slipping.

In his half regressed state he didn’t think about how he could just write „same“ and go next door to be little with Eiji, no. The only thing he thought was „I’m too late.“.

As a result he forcefully tried to hold onto his big headspace. He couldn’t slip without anyone around… he wouldn’t want to admit it but regressing alone became scary for him. God he was so needy… no wonder they all liked Eiji more. Eiji didn’t fuss around when no one was there to hold him. Eiji didn’t cry when Sero ignored him that one time because Suki showed the carer something. Eiji didn’t even as much as pout when Suki didn’t look at him or snapped at him because he copied his movements.

Suk-Bakugous brain was full of fog and a headache was creeping in after he sat on the ground for about an hour, starring into nothing and fighting against the mushiness. It didn’t help that he heard Minas or Denkis voice from time to time, or giggling and laughing. He turned around, grabbing his phone. Maybe that’ll distract him?

But it didn’t because he saw another message. It was from Sero asking if he wanted to come to Kirishimas room. He probably doesn’t mean it right? He just texted that to make Suki- Bakugou! To make Bakugou feel included… right? If he were to come over they would be annoyed because Suki can’t do anything alone. But god, he wanted to go over! He wanted Sero to hug him and Denki to play with him and Mina to pat his head and Kirishima to-
No!

He’s a big boy! He can do that alone! He can already regress without carers! Who even needs carers? Only babies! He can do that alone and then he’ll tell them and they will all be so proud of him for doing it alone! They’ll be so proud that they’ll all hug him and compliment him and Eiji will look at him with big eyes and a lot of admiration and say what a cool big brother he has and then no one will see him as needy or annoying and they’ll all need him because he’s the best!

He stood up, swaying slightly and toddled over to his pacifier and teddy, that were placed inside of his drawer. As soon as he put the pacifier into his mouth and started popping it the fuzzy feeling took over. But not completely quite yet! He needs to stay big enough so that he won’t be scared because that’s only what babies are!

But it proved to be very difficult to willingly stay in that floaty middle ground. He really, really wanted to just let go. To just let himself fall and someone taking all responsibility from him so he didn’t have to worry about anything. To just not care what was going on in the outside world… and finally he lost that fight and everything instantly just got too much. It hit him how alone he was. How helpless he actually was if something were to happen.

He was too small and he still was getting smaller. He just wants his carers. He just wants them to hug him and- no. He… he should be able to do this! He did it before they all found out so why is this so hard now?! He’s so stupid!
He can’t-

There was a knock on the door that made Suki jump. No. Nononono. It’s scary. He’s scared. Who’s knocking?! What do they want? He has to get out of headspace! Now! Now…
Not possible. No matter how hard he tried to pull himself out it was useless. It only made his headache worse and nausea was setting in. It’s too much.
The blanket he wrapped himself in was too hot, the fabric rubbing on his skin like needles. The air in his room none existent. The knocking too loud. Too loud. It’s too much.

Suddenly there was red hair in his vision before it was gently pushed behind and exchanged with pink. Through Sukis tears he couldn’t see their faces but he knew who they were.
„Honey, don’t hug Suki right now. Stay here ok?“, Minas voice sounded silent, whispered. Suddenly black and yellow where there and Suki could hear Denki talk „Hey buddy. Is it ok to touch you or would that be too much right now?“

Would hugging be too much? Through his clouded brain he tried to think straight. Did he deserve a hug? He was a brat. He didn’t deserve it right? So he shook his head. „No? No touching?“, Suki nodded. „Ok, that alright little buddy. But I still need you to take deep breaths ok? We practiced this before remember? In and out.“, Sukis vision was clearing up a bit and he could see how Denki was demonstrating the breathing technique.

It took a bit but he gradually calmed down. „Would it be ok if I sat beside you and patted your head little one?“, Sero was kneeling in front of the bed, right besides Denki. Suki thought for a bit before nodding. The mattress gave in a bit when Sero sat himself next to Suki, making the little fall a bit into his direction. Sero gently placed his hand on Sukis head and pulled him onto his shoulder. „Do you want your paci again buddy?“, Denki held the pacifier up into the air for Suki to see. When did it fall out of his mouth? But despite that question he still nodded.

„Suki otay?“, Eijis voice came from behind Sero and Denki. The redhead was now standing right at the door with Mina holding him in place. It was clear that the little wanted to go to Suki to hug him. „It’ll be alright honey. Suki just needs some time. Let’s go back to your room ok?“
„Bu-", and Eiji got dragged out of the room again. Now only Sero and Denki remained.

Suki stared at his door. Mina was probably annoyed right? Why else would she drag Eiji with her? He didn’t want-
„Hey, buddy. If you were feeling small why didn’t you text or come over mh?“, Suki shrugged and buried his face in Seros shoulder. „Don’t feel like talking? It’s alright.“, Sero gently tugged at Sukis hair a bit. It was grounding and calmed him down more and more. He wasn’t alone anymore. But… he felt as if he lost.

They stayed silent for some time until Suki finally tried to speak again. Most was muffled or got caught in his throat again. „M big an don ne-need care‘s an u have E-Eiji.“
„Oh Suki.“, Sero pulled away a bit to look the blond in the eyes „I don’t think you are big enough to be alone right now sweety. And if we didn’t want you to come over I wouldn’t have texted you, would I?“, Sero gave a small smile but Suki look away.

„U jus want to make me feel bedder…only be annoyed.“
„Buddy we always want you to feel good. We’d never be annoyed at you coming over. Why would you think that?“, Suki shrugged. „Be‘ause u think m clingy an no as good as Eiji.“
The carers looked at each other, that’s kinda what they feared for to happen at the start of this, that’s why they tried their best to give the little all he wanted, giving him hugs when he asked, giving him space when he seemed to need it and- oh. He probably misunderstood that, didn’t he?

„Buddy listen! We love you and Eiji both the same ok? We don’t think either of you is annoying or too needy. It’s normal to want hugs and attention Suki, ok? But you have to tell us what you want, we grownups can be really stupid from time to time ok?“, Denki grimaced at the last part making Suki giggle a bit. „This was a huge misunderstanding ok? We thought you wanted more space and you thought we didn’t want you anymore right?“, Sero placed a kiss on Sukis head as he nodded.

A misunderstanding? So they don’t think he’s too clingy? „How old are you right now buddy?“, Suki thought for a while. He was exhausted from keeping himself out of little space and crying… 3? Yeah, sounds about right… so he put up three fingers. „My!“, Denki smiled brightly at Suki. „Do you think you’d want to play with Eiji a bit or do you want to stay here with us buddy?“, he didn’t want to get up just yet so they stayed like that about five minutes more in comfortable silence till Sero spoke again.

„Suki, I know it’s been hard for you but I still need to say this ok? I’m not angry with you but please listen. You behaved very rudely to Eiji the last few weeks, you know that? It hurt him a lot.“, Suki twitched. He knew. He was awful! He-
„So-sowy!“, he sniffled.
„Now now, that’s no reason for more tears Suki. It’s good that you know that that behavior was very wrong. So don’t apologize to us because you weren’t rude to us but to?“
„Eiji?“
„Yes buddy, very smart. And what do we do when we were rude to someone even though they didn’t deserve it?“
„Apologice to em?“
„We have such a smart boy here!“, Sero squeezed him tightly and Suki smiled.

„Otay! I wanna go to Eiji!“, the other two smiled widely at that. „Good idea buddy! Let’s go.“

Eiji was sitting on his bed with Mina still holding him. Maybe because he’d try to go to Suki? When the two carers and the little knocked at the door and let themselves in Eiji actually almost really jumped up. „Suki!“, he beamed trying to free himself from his carer. Suki stopped in the middle of the room and looked to the ground, fidgeting. Sero nudged him gently „You wanted to say something to Eiji right?“
„You can do this buddy!“, Denki gave a thumbs up and Suki took a deep breath.

„M sowy for bein mean to u when u were really nice to me!“, He said it really fast but Eiji still seemed to have understood it because he smiled so wide that one could see all his teeth. „Is otay. Mh… I was really sad an all bu it’s otay now!“
„Sowy…“, finally Mina let go of Eiji and the redhead dashed to Suki and grabbed his hands. „Let’s play something!“, Sukis eyes grew wide. He didn’t expect the other little to just move on like that, then again they were both little kids right now so when Eiji pushed him to play heroes he quickly forgot about his bad feelings as well.

After that their whole dynamic shifted for the better. Suki finally started to really play with Eiji and you could think that those two really were brothers. They started to stick together like glue, if one wasn’t there the other would be completely lost. If they were separated they’d start crying.
It got to the point that, when one of them would wake up regressed they’d go to each other’s rooms even if they had a rule that stated that they can’t be both little and without caregivers.

And even if Suki from time to time still was a little brat to Eiji he almost immediately would apologize as soon as he realized his wrongdoings.

It got peaceful again. Well, as peaceful as it can get with two littles and three carers.

Notes:
