Don’t mind me with this self indulgent little fic of Izuku and Shouto having huge crushes on Y/N, and Bakugou being a jealous shit <3

“What the hell?!” you say, confused as Aizawa comes to you, Ochako and Tsuyu, holding two small versions of your former friends, Izuku and Shouto.

“Don’t talk like that, L/N,” Aizawa said, exhausted. “They got hit with a quirk that reversed their bodies, they’re both about three right now. The quirk should wear off in about a day,” he told the three of you as he handed you little Shouto, and little Izuku to Ochako. “I trust you three will be able to watch them. I have a lot of work to do,” he said before leaving. 

You stand there, holding a toddler Shouto, watching your teacher abandon you. Sure, you were now third years and could definitely take care of kids, but why was he dumping this on you? Just because you were close to them? 

A gentle pat to your cheek makes you look down at the cute heterochromic eyes. 

“Oneesama?” little Shouto says, looking at you with big eyes. 

“Oh, do you remember me?” you wonder, smiling.

Little Shouto shakes his head slowly, “N-No…?” he says, but you can tell he’s struggling to keep up with everything. After all, a toddler's brain is a bit different from a teenagers. 

“It’s okay, don’t push yourself. I’ll take care of you all day, okay?” you say, grinning.

“Me too!” little Izuku says, wiggling in Ochako’s arms. 

“Yes, we’ll watch you too, Izuku,” Ochako says, laughing as he hugs him. He wiggles in her arms until she lets him go, running over to you, holding out his small hands for you. Ochako pouts a bit, crossing her arms.

“Midoriya, they’re holding Todoroki,” Tsuyu says, “Want me to hold you?” she offers.

Izuku shakes his little head, looking up at you with big green eyes. 

“Well, can I hold you, Todoroki?” Ochako wonders.

Shouto frowns and hugs around your neck, his little eyes glaring.

You sigh and adjust Shouto so he’s sitting on one hip before picking up Izuku and holding him on the other.

“Sorry, I have this effect on kids,” you say with a nervous laugh. In reality, you have no idea why these two were acting like this.

Ochako keeps pouting a bit, but accepts this and offers to get them some snacks, disappearing into the kitchen.

Both small boys cling to you as you move to the couch, not wanting to hold them for longer than necessary. As you sit down, both boys snuggle into either side, holding onto your shirt as if you planned on leaving them. 

“What the fuck?” you hear, turning your head to see Bakugou looking over at all of you.

“Hey don’t cuss in front of kids!” Ochako complains as she comes in with the snacks, setting them down on the table.

“Those are no fucking kids! What happened to Deku and Half n Half?!” Bakugou said, frowning as he walked towards the couches. 

Kirishima and Kaminari are behind him, “What’s going on?!” they both wonder, heading towards you on the couch to get a better look at what was happening.

“They’re still kids!” Ochako retorts.

“Well-” Tsuyu starts to explain but gets interrupted by a loud voice.

“WHAT HAPPENED HERE?” Iida shouts from the doorway, his arms karate chopping the air in a panic. Everyone is starting to get back from their individual activities, so the room quickly crowds, confusion swirling.

“Will everyone just BE QUIET?” you say, annoyed, but loud enough for everyone to hear you. You’re covering both boy’s outer ears and pressing their small heads against your chest to keep them from hearing your shouting. Shouto looks irritated, clinging to you, while little Izuku looks more confused.

“Now that that’s settled…” you say, letting the small boys free, but Shouto clings to you and Izuku stays close, looking at everyone with curious eyes. “Okay, everybody, the two of them got hit with some kind of quirk that turns people into toddlers,” you explain as much as you can, not knowing much since Aizawa really didn’t either. “They should be back to normal in a day or two, but we all have to keep an eye on them, okay? Aizawa-sensei would really like us to do this favor for him, since he already has Eri to worry about.”

“They seem to both really like Y/N, though,” Tsuyu said offhandedly, the way she always did. She was just a direct person like that. 

“Yeah we’re sure you’ve got this!” Kaminari and Mineta said, the two of them running off. Neither wanted to be stuck with little kids. 

Bakugou just tch’d and left, loudly proclaiming he wouldn’t help, Kirishima apologizing and chasing after him. 

Aoyama offered to help with little Izuku, but Izuku nearly cried when he tried to hold him. Oh, lovely. Izuku would throw little fits anytime someone but you tried to hold him, while Shouto didn’t even let go of you, as if his life depended on keeping you close. Eventually, you were left with the toddlers with only Iida and Ochako to help you. 

Izuku had finally warmed up to the two of them, which left you holding Shouto on your hip, him not wanting to leave your side. 

“Onee-sama, I’m hungry,” little Shouto said, looking at you with big eyes.

“Ah, well, let’s go see what we can find,” you say, taking him with you as you leave the common room.

Right as you turn the corner, you hear loud crying, followed by “Hey, come back!” from Iida. 

Turning, you see little Izuku running towards you whining “Don’t leave me!” before he crashes into your leg, clinging to it. 

“Izuku, I’m not leaving…” you say, gently patting his fluffy green hair. “Shouto is hungry, are you hungry too?” 

“Come on, Midoriya-san, let’s go back into the common room,” Iida tries to pursue the small green haired boy to go with him.

Izuku shakes his head at both questions and grabs onto your leg tightly, burying his face in it as he sniffles.

Shouto pouts at the fact Izuku stopped you from getting his food, gently kicking his leg towards Izuku’s head. It connects, making Izuku scream and sob again, even if it hadn’t been that hard.

“Shouto!” you scold, frowning. Iida is shocked and tries to help, but you gently wave your hand at him to tell him you have it handled. 

Shouto buries his face in your neck, mumbling sorrys. 

You set him down, “Apologize properly,” you say sternly.

Shouto whines at being let down, grabbing onto your wrist and trying to pull himself back up, but you slip your arm away from his tiny hands. You get down on your knees and gently rub Izuku’s head.

“S-Sorry…” Shouto says, pouting and looking at Izuku before looking at you.

“For?” you prod.

“For kicking… your head..” he said, holding out his little arms for Izuku. Izuku blinked and wiped away his tears, hugging Shouto tightly, sniffling a bit. 

“Now can we be nice? I have enough attention for both of you, okay?” you whisper, ruffling both boys' hair. 

Shouto’s eyes light up, grabbing your pant leg and nodding. 

“Yes!” both boys said together.

Izuku clings to your other leg, but you make them both let go in favor of your hand, leading them both into the kitchen. 

“Okay, Shouto, what do you want to eat?” you wonder as you start looking through the cabinets. 

“Soba!” he said happily.

You blink, wondering if you even have that. You rummage around, finding everything you need before you start to cook. “This’ll take a bit, just sit tight, okay?” you tell the boys.

As you cook, you don’t notice the boys getting out of their seats, at least not until you feel small hands gripping at your shirt hem on either side. 

“Ah, boys! Stay away from the stove, it’s hot,” you say nervously, but when you look down they are both looking at you with big eyes. “Not much longer, okay?” you reassure them. You really wished this hadn’t happened, or that the toddler versions of the boys would at least be willing to let someone else watch them. They both scootch back a bit, staying behind you but not going back to their seats. “Fine, fine,” you mumble, wondering if they would remember this when they turned back to normal. 

They definitely both would owe you, even if they didn’t. You finish up making everything that's needed, the boys both watching you curiously as you move around the kitchen. The two had agreed to stand in one spot away from the sink as you drained the water and finished it all up. Finally, you put everything on the table for Shouto, sitting down and laying your head on the table. 

Shouto sat happily across from you, eating his cold soba like a pro, even as a toddler.

Izuku sat beside you, watching you, “Tired, onee-chan?” his little voice asked, gently patting your leg.

“Ah, a little bit. It is getting late…” you say, pulling out your phone and noticing it was nearly 7pm. Ah, shit, where were the boys going to sleep? Toddler versions couldn’t sleep in their own dorms, so far away from adults and likely behind a locked door. They would definitely get into trouble.

“Where are we gonna sleep, onee-chan?” Izuku asked, looking at you with bright eyes.

“Ah… I guess I’ll have you two sleep in my bed and I’ll sleep on the floor,” you say, figuring it would be easier that way. They wouldn’t be able to escape the room if you slept near the door. “That way you’re safe,” you say, smiling. 

“Hey, is that going to be okay?” you hear a voice, turning to see Bakugou standing near the kitchen door.

“Why wouldn’t it be?” you wonder.

“Because those little brats are all touchy with you,” he says, “Wouldn’t it be inappropriate to sleep near them? They are boys.”

You roll your eyes, “They’re toddlers. It’s not like they’re going to try anything,” you retort. Shouto glares at Bakugou, hopping down from his seat and scampering to your side, clinging to you. 

“See? That shit right there!” he snaps, “Stop touching Y/N so casually, half and half little brat!” 

“Bakugou, they are children right now! Stop acting like that,” you say, standing and picking both boys up, Izuku buried into your neck whimpering at Bakugou’s voice so close.

“Oi! Deku stop that shit!” he growled out, about to grab Izuku before you moved back.

“Don’t touch him, they’re under my watch. He can do what he wants,” you say sternly, frowning.

“I’ll watch them, then!” he growled, going to grab Izuku. 

You purse your lips and hold both close as you swiftly spin around Bakugou, avoiding his grasp. “No! You’re going to make them cry!” you say, about to leave the kitchen before he grabs the back of your shirt, stopping you.

“Then give them to someone else!” he shouts.

“What? No! We tried that. They want me!” you reply in a loud voice.

“So do I!” he shouts back, his ears going red as he realizes what he said. His crimson eyes get a bit bigger, then he quickly looks away. “Ugh! Nevermind!” he snaps, “Just leave!” 

You’ll definitely have to come back to this, but right now the toddlers in your arms are basically throwing fits. You groan, “This isn’t over!” you tell Bakugou before leaving, the boys calming down only a bit as you get into the elevator. 

You set both boys down and sigh, burying your face in your hands. What the frick just happened?! Did Katsuki Bakugou, the rudest boy you knew, just confess to you? This was definitely not the time for that to be happening. 

Izuku came up to you, tugging on your shirt.

“You… okay onee-chan?” he asked.

“Ah- yes I’m sorry boys… I should be watching you better,” you say, sniffling before you smile at them both.

Shouto didn’t say anything, but clung to you tightly. You smiled and led them to your room, letting them run inside as you took off your shoes and set them beside the door. Izuku runs to one of your All Might figures and admires it, while Shouto goes straight to your books and begins to look through them. 

“Sorry, I don’t really have kid stuff…” you say, trying to decide what to do with them. After texting Momo for some help for something for the boys to sleep in, you settle in and start cleaning an area for you to sleep on and move things breakable out of their reach. 

She brings them rather quickly, two cute little sets of feety pajamas, each looking like the boys hero costume. 

“Oh my gosh they’re great Momo! Thank you so much!” you say, beaming. You had been very concerned they would have to sleep in underwear or their current clothing. 

“No problem!” she replies. Momo says hello to the boys and gushes over how cute Shouto is, revealing she had made a few other things to keep the young boys entertained. You thank her multiple times before she takes her leave, saying goodnight. 

“Oneechan? I.. have to go pee…” Izuku said, whimpering softly. 

“Ah, oh shit, ah, okay.” you say a bit panicked, you hadn’t thought about this. You lead him to your small private bath that has a sink and toilet. “D-Do you need help?” you wonder.

Izuku shakes his head and you close the door, sighing out of relief. 

Shouto is suddenly beside you, clinging to your side, “Onee-sama…” he murmurs, looking a bit nervous as he looks down at the ground.

“What’s wrong, Shouto? We’ll play once Izuku is done, okay?” you reassure him. Shouto nods slightly, still clinging to you. Izuku comes out a moment later, and luckily only needs help washing his hands. Thank goodness the outfit was simple pull down pants and not a zipper.

Playing with some of the toys, you all end up playing heroes with the figures, which turns into them running around and “saving” you from each other. After a while, both of them are tuckered out, yawning loudly as they start to slump. 

Looking at your clock, you notice it’s nearly 10pm, way past the time most would put a toddler to sleep. Groaning to yourself, you get both boys changed rather easily into their pajamas since they’re so tired. You get them settled into bed, but they both whine when you try to leave them.

“Onee-chan!” Izuku whined, “Stay.”

“Please, Onee-sama…” Shouto whimpered, both of them holding onto your hands.

You sigh, their big eyes too much for you. “Fine, fine. Let me go change…” you say, them reluctantly letting you go. Going to your bathroom, you quickly change into your pajamas and brush your teeth, trying to reason with yourself that the boys only like you so much because children have an odd attraction to you. You grew up around a lot of them, after all. 

Going back out, you find that Izuku has passed out, and Shouto was nearly there. Luckily, he doesn’t notice you in the dark room, as you lay down on the bed you had made for yourself. Yawning to yourself, you find as soon as your head hits the pillow, you’re passed out.

Groaning to yourself as you wake up, you shift a bit to feel two large muscled bodies against either side of you. Blinking your eyes open, you shift your eyes towards a fully grown Izuku, and look the other way to see a fully grown Shouto. They must have moved down here sometime in the night. Unable to help yourself, you let out a slight scream, sitting up immediately, feeling both their arms that had been crossed over your torso fall into your lap. The loud noise and movement caused both to stir, Izuku waking up first.

“Y-Y/N?” he stutters out, looking around and trying to figure out what the hell was going on. He pulls a blanket over him, his face bright red.

Their pajamas had obviously torn when they had suddenly grown sometime during the night, leaving them both nude on either side of you.

Shouto groans, his mismatched eyes opening and looking around, equally as curious. He doesn’t seem to notice he’s naked.

Quickly, you’re out from between them, standing near your door, “D-Do you two remember anything about yesterday?” you wonder, worried they would both be angry with you for the situation.

“We… got hit with a quirk?” Shouto says, trying to remember.

“Y-Yes, and got hit turned into kids! For the day! A-And.. Erm..” you say, trying to figure out how to really explain.

“It’s.. coming back…” Shouto said, frowning as he held his head. He finally seemed to notice his nudeness, covering himself quickly as he tried to process everything.

“O-Oh god!” Izuku says, hands on his head as both of them seem to be getting flashes from yesterday.

“We.. stuck to you… so embarrassing…” Shouto says, his voice showing his shame as he looks down, embarrassed. 

“No, no!” you quickly say, “It’s okay!” you try to reassure him. “But… I do.. wonder why…?” you ask out loud.

Izuku looked up quickly, his soft features even softer, “I… It’s likely because I have feelings… for you…” he admitted honestly, his face bright red.

“Ah, yeah, same for me. Probably…” Shouto said, slowly looking up. 

Looking between the two boys, you can feel your face heading up. 

“You don’t have to respond right away,” Shouto said, noticing your face.

“What happens if I like… both of you..?” you wonder quietly, the boys eyes snapping to your face, unsure if they heard you right.

“Well…” started Shouto.

“I guess we’d have to discuss?” Izuku finishes.

Ry: Sorry for ending it here…. I figure it’d be more fun that way. Hope ya’ll enjoy (owo;;)
