During their second year, Izuku accidentally slips when they're watching a movie (it was Big Hero 6 and he loves that movie!). Before he knows it, he is sitting with his legs curled up and the hand he was using to pick at his lower lip just slips the thumb into his mouth.

No one really notices at first, all content on the movie or sleeping. Izuku just watches, wide-eyed with excitement at the display of heros on the screen.

He's sitting in between Shouto and Ochako, with Iida on Ochako's other side and Denki and Sero in front of them on the floor. Kacchan sits on the loveseat by himself to the right of the room and Mina, Kiri, and Tsuyu have the other couch on the other side.

No one notices the thumb-sucking for a good third of the movie.

Izuku isn't super little or anything, maybe 4 or 5 years old... he just likes putting things in his mouth and his fingers are usually the first to go in. It is a comfort habit of his. It is why his favorite candies are lollipops and suckers; some people would call it an oral fixation.

Really no one notices until Shouto glances over and in his usual calm tone asks, "are you sucking on your thumb, Midoryia?"

He looks over, turn his head and keeping his thumb securely on his tongue, and cocks his head to the side. No one has ever asked him about it; the only person he's really been around is Kacchan when he is like this and the blond has never asked him about it.

When he glances around, he sees a lot more eyes on him than he was used to. It makes him shrink his head into his neck a little and he doesn’t know what to do. His thumb slips from his lips.

"Is't bad?" he asks in a voice pitched a little higher than usual.

"What?" Ochako asks right next to him, genuine curiosity in his voice; not that his little mind can comprehend that.

Izuku looks around wildly until he finds a familiar face. The moment he looks over, Kacchan glances away from the movie for the first time to tune in to what is happening.

"Oh shit," he mutters, sitting up from his reclined spot on the couch.

The curse makes Izuku giggle, yucky feelings disappearing now that he know Kacchan's here! "Hehe, dats'a bad word," he giggles.

Katsuki stands up and doesn't look away from Izuku's face when he asks, "how old are you right now, Izuku?"

Izuku stops and thinks about it for a second. Then he holds up four fingers.

And that is how the majority of class 2-A finds out about Izuku being an age regressor.

Izuku keeps cumming prematurely. It's to be expected, really, he was a virgin when you met and he gets worked up easily. You've never held it against him- in fact you find it pretty hot. He always keeps going, though it can be hard for him. Too intense. And embarrassing in his eyes. He's a firm believer in making your partner cum first. So you had to come up with something to help him hold off for a few minutes, for his sake.

That's how you end up on his lap, telling him to talk you through his last homework assignment or his favorite anime. He rambles through equations or plot points in extreme detail while you ride him, asking him questions to keep his focus off of your pussy and on whatever topic he chose. It works pretty well- he doesn't cum within the first fifteen minutes if fucking you, and you think it's hot when he rambles. It's a trait about him that initially attracted you to him in the first place. You love your nerdy little boyfriend and his rambling <3

Aftermath of the Accidental Slip

a/n: This is part two in my Little Heroes series, you do need to read the first part to understand what they are talking about in this fic. You can find the first part HERE

summary: The day after the movie night, some of Izuku's classmates and friends have a few questions. So they ask and maybe Izuku has a lot more to gain from the conversation.

~

It is the next day when Denki is the first to ask about it. They’re sitting in the common room and Izuku is buried in his books sitting at one of the tables in the area behind the couches when Denki plops himself in the seat next to him. 

“What’s up?” Izuku asks conversationally, looking for any excuse to get out of doing his physics assignment. 

Denki leans forward and his eyes dart around the room wildly for a second, as if he were scanning who all is in the room with them (it is the middle of the afternoon so there are some people here, but it is the usual group that chills here after classes get let out: Kacchan, Kirishima, Mina, Uraraka, Tsuyu, Iida, and Todoroki). Izuku also realizes that everyone here today was with him last night when he…

He ended up regressing during last night's movie night (not that he blames anyone, but come on, they played his favorite kiddie movie!) and no one really asked about it then. At least anything that Izuku can remember. They just sort of sat back and watched the rest of the movie and let Izuku keep sucking his thumb after Kacchan had given a very brief explanation of the headspace he’d been in at the time. A very, very brief explanation. 

“I just wanted to ask you about something,” Denki asks in a slightly hushed tone, putting emphasis on the final word so that Izuku could maybe understand what he was talking about. 

“Is it about last night?” Izuku asks anyway, just to make sure. 

Denki nods his head, his hair bouncing with the movements. 

Izuku has been waiting for someone to ask him about it specifically, but he wasn’t prepared for it to be quite literally the next day. He supposes he is just glad it wasn’t last night though, his poor littleself would have been so confused. After the movie was over, Kacchan declared it bedtime for the both of them, and he made sure to tuck Izuku under the covers in his bed with his favorite stuffed All Might toy before leaving to presumingly go to his own. 

He hopes that the questions aren’t too invasive, but he also wants to spread more information on the topic as well. Izuku thinks his entire class would benefit from gaining more knowledge on age regression; in fact, he thinks some of his peers might even be regressors themselves but they just don’t know it yet. 

“Okay, shoot,” Izuku gives the electric blond permission to ask his questions. 

“Is it something that you are comfortable talking to all of us about?” 

The question throws Izuku off for a second and he immediately cocks his head to the side and watches Denki’s face carefully. His immediate response is to ask who all of us are and when he finds out that it is everyone from last night then he relaxes some. Yes, he wants his class to learn more about regression but he doesn’t want to jump right into giving a lecture about it in front of the whole class! Especially not about his own littlespace adventures because he’s not sure how a handful of them would react…

“I have no problem talking about.. about it, no. But I-uh, like, what do you want to know?” He can’t help the stutter in his voice, it flairs when he’s nervous. His stomach is in all sorts of twisty knots over this. 

Izuku’s regression means a lot to him and he hadn’t expected that he’d be comfortable around so many people at once to slip as he had, but as long as everyone remains respectful he doesn’t mind talking about it. 

Denki shocks him again by looking up and waving everyone over to the table excitedly. 

“Wha—” Izuku asks as more people suddenly sit at the table. 

“D’you ask him?” Kirishima asks the blond sitting next to Izuku while he sits down in his own spot. 

“Yep!” Denki looks proud of himself. “He said he has no problems talking about it, right?” A moment of doubt flickers across his features as he waits for the subject of the conversation to confirm his statement. 

“Oh, I-I didn’t realize you all had questions- or wanted to talk about it, or whatever. But-but yeah! I don’t have a problem with it if you guys don’t…” it is hastily thrown together, but Izuku does throw that corroboration out there. He ends it with a simple, “what do you want to know?”

Uraraka eagerly throws her hand in the air and rocks in her seat until Izuku laughs at her and “calls” on her. 

“I wanna know more about it in general! I did some research last night and it sounds neat. I was just curious what it feels like for you specifically—”

“Oh!” Iida cuts her off to add, “and what triggers the regression, and what your signs are so that we can help out better the next time it happens. I felt a little bad just ignoring you last night, but I didn’t want to upset you… I don’t know much—” he pushes his glasses up the bridge of his nose and smiles a little as he speaks, “—but I do know it can be a fragile mindset for some people. So I wish for you to enjoy doing it around us rather than the opposite.”

The rest of the group nods their heads and agree that they all feel the same; they all tell Izuku how they would much rather be more prepared in case it happens again. 

It warms Izuku’s heart so much, his insides feel gooey in a matter of seconds. His friends and classmates care so much for him, he just hadn’t really realized it until just now. “You guys…” Izuku felt the prickle of oncoming tears behind his eyelids and he blinked rapidly for it to go away. “...thank you.”

Kacchan, who had been resting on one of the couches reading a manga book, now gets up and walks over to the table. 

Izuku knows he was within earshot and so he isn’t surprised when the fiery blond inserts himself directly into the conversation. 

“You wanna know what his tells are? Because I can tell ya them better than he can,” he grins triumphantly, as if being better at this somehow mattered in his overall plan to be better than Izuku. Hell, maybe it did matter because Izuku didn’t really know how to answer their questions. He’d never really thought about the during too much, it all just felt like a sweet pillow of cotton candy in his head during. It is stress-free when he is little and with Kacchan. 

“Oh, that would be helpful, Bakugo,” Todoroki says, much to the agreement of the rest of the group. 

Kacchan throws himself into the remaining open seat and slams his elbows on the tabletop. “Fine, then I will tell you as long as the nerd is okay with it?”

Izuku hides his grin behind his hands and nods his head. He remembers a time when he’d been scared to open up to Kacchan about his regression, fearing he’d just be giving the other boy a weapon to use against Izuku. However, the blond had been the most loving, caring, and thoughtful person to Izuku when it comes to his littleself. 

Actually, it wasn’t long after he found out that he’d been taking care of a small-minded Izuku in his dorm while he did homework. From there they both found comfort in the regression (for Izuku it is the act of being cared for, and for Kacchan it is feeling the sense of purpose as a caregiver). 

So… between the two of them, they cover all of the bases and retell the story of how they found out. They haven’t been doing this for very long so it doesn’t take a lot of time to retell everything. 

“So it was the movie last night then?” Ochako asks. 

Izuku squints down at his hands resting on the table overtop his open textbook, his studying has long since been forgotten about. He thinks about the question for another second before looking back up to meet the eyes of his friends. “Honestly, yes, but it doesn’t always happen. I mean- I’ve uh, watched kids' movies with everyone before without regressing…” 

“Was it that specific movie?” 

“Uh, no, I think I just had a stressful day and that mixed with the movie just caused it.”  He is pretty sure that’s what caused the regression the night before, but it isn’t always important to figure out the why part. Sometimes he just needs the mental break and he tries not to fight it when he can, and a part of him knew that last night he was safe and comfortable enough.

“Hmm.” The group takes in the information while Iida speaks, “do you always know you’re going to regress? Or does it just happen?”

Izuku shrugs, “kinda both.” 

“Okay, another question,” he clears his throat and starts talking again, “if it just happens around any of us, would you like us to take care of you like Bakugo does?” 

Izuku’s eyes widen and he immediately shoots his gaze over to Kacchan himself. Was Iida really asking to be his caregiver here? Well, the title might be a bit premature, but did they really want to care for his littleself? It can be quite a bit of responsibility… especially when he goes really young and he does get fussy sometimes and he knows that that isn’t really enjoyable for anyone. Heck, sometimes he wonders why Kacchan even stays to help—

“I-zu-ku,” the voice of Kacchan pronouncing each syllable of his name startles him out of his own thoughts. 

By the look on everyone else’s faces, the green-haired boy knows that he said all or nearly all of that out loud. Oh god, he really does have the tendency to mumble. 

“I’m sorry,” he looks back down at his hands. 

“I didn’t mean to ask if it was going to stress you out, Midoryia,” Iida consols. 

“Oh no, no, that’s not it!” Izuku waves his hands erratically in the air and feels bad for the misunderstanding, so he corrects himself right away. “Being a caregiver can be a lot sometimes—”

“—please, you’re easy—” 

“—and I just want you guys to know what you’re signing up for, you know?” 

Iida hums thoughtfully but doesn’t say anything. Uraraka grins wild enough for her round cheeks to push out even further. And as Izuku looks around to table, he realizes that the silence isn’t awkward but maybe a little energetic? Everyone has clear or happy looks on their faces and the green-haired boy can’t help but feel like something is coming. 

Uraraka is the first to break. “But taking care of little you would be so fun because you’d be so cute!” Her voice gets all squeaky by the end and she starts kicking her legs under the table and bouncing in her seat; she is very clearly excited about this. 

“Ochako,” Tsu speaks up in her plain tone, “you have to make sure it is okay for you to coo over him first, ribbit.” 

Uraraka slaps a hand to her forehead and mumbles oh yeah! before turning her gaze back to the subject of their conversation. 

“I would also like to know the answer as well,” Todoroki says. 

Izuku’s head is spinning. 

“I am sorry if that weirded you out, Deku,” she says honestly, “I just- ever since I was looking more stuff up last night I started getting all of these ideas and I would love to have a play date with you!”

“Wait—” Izuku stares wide-eyed around the table when he notices some agreement. Then they start adding to it to further blow him away.

“Yeah, man,” Kirishima speaks up, “it would be cool to make little kiddie snacks and maybe play some video games, depending on how little you go, of course.” 

“Oh!” Denki joins in, “I read that cuddling is also a really big thing with regressors, so that would be loads of fun. You know me, always down to get my cuddle on!” He jams two thumbs in his own direction with his signature goofy grin and Izuku is too busy trying to keep up with all of them to even laugh at it. 

“Wait—” he tries again, “now hold on.” 

“Also just making sure you are cared for would be a huge benefit for the class, as you don’t typically do that on your own anyway—”

“Okay, slow down!” Kacchan barks, cutting off all conversations that were starting up at once. “Let him speak for Christ’s sake!” 

After the shock of such a loud voice, everyone else quiets down. Izuku takes his chance to speak now: “Thank you, Kacchan,” he starts with. Then he flattens his hands overtop his book and takes a breather to collect himself before speaking, “first, I would love to have more of you involved with my regression if you’d like but I suggest you be with Kacchan and I for a while first. It isn’t always happy and stress-free when I am little…” 

He stops for a minute, remembering with quite a bit of embarrassment all of the times he’s been fussy or thrown literal temper tantrums when little. Almost all of which Kacchan had been there to soothe him as best he could. And then there are the times when he couldn’t sleep and how his neediness would impede on Kacchan’s schedule (even if his friend said it didn’t matter, Izuku always knew when he was big again). Being someone’s caregiver is a lot of responsibility. 

“Izuku,” Kacchan starts, his tone hinting at the start of a possible argument. 

Izuku speaks again before he can say more. “What, am I wrong? I’m not bashing myself here—” he doesn’t look away from the boy he’s talking to for a second, “—I just know that all of the crap that is wrong in my head doesn’t always go away when I am little. Sometimes I’m upset, sometimes I can’t sleep, and sometimes I am just needy.” 

He does turn to the others now, needing them all to know this. “Kacchan and I stumbled into this kind of relationship, but I want you guys to know that once my littleself trusts you, you can really mess me up by leaving. And that trust builds after a while, so we can tiptoe around it for now, but being one’s caregiver is big. Are you sure this is what you want?”

“Just because we didn’t plan on it,” Kacchan interjects, not looking anywhere but at Izuku so that he knows what the blond is speaking is the truth, “doesn’t mean I regret any of it. I know I probably don’t say it enough, but I do enjoy taking care of you like that.” 

Izuku smiles, his vision blurring a little with unshed tears once more. And once more, he blinks them away. “I know, Kacchan,” he says. “I like that you enjoy it, actually, I need you to. Knowing that it helps you just as much as it does me makes me feel less guilty…” he admits. 

“You shouldn’t be feeling guilty at all, ya damn nerd.” 

Izuku looks away at that, he doesn’t have any sort of argument there. He knows he shouldn’t be feeling guilty, but sometimes the reassurance when he is big is just what he needs. He and Kacchan have always been enough and have always known exactly what the other needed. It took a lot of missteps and a hell of a lot of bumps in the road, but being here with him after so long is perfect. Izuku wouldn’t want to take this journey with anyone else. 

But before he can get too lost in his thoughts and his appreciation for his best friend, said friend’s voice pulls him out. 

“Let them help too if you think it is too much for me.”

Izuku sighs, letting Kacchan hit it right on the nail yet again. He looks around at the rest of them, gauging their varying reactions to the two of their’s conversation. He’s grinnig by the time he is ready to start circuling back to his original speech from a little bit ago, “the second thing I wanted to say is that I don’t mind if you call me cute or ‘coo’ over me or anything, but please save it for when I am little. We can talk more about boundaries and stuff but I do know that hearing you guys talk about it while I’m big makes me feel weird—”

“I’m sorry, Deku!” Uraraka covers her mouth with her hands and Todoroki puts a comfortingly warm hand on her shoulder. 

“—no, you’re okay! I’m just more likely to argue with you when I am big, but my uh… heh, yeah… just not when I am big,” he laughs off the rest of his sentence and rubs at the back of his neck. He was gonna say something about his littleself, but he might want to save that for another time, or like never—

“He eats that shit up when he’s little,” Kacchan says plainly, looking all nonchalantly at his nails. “That’s what you were going to say, wasn’t it?”

Izuku blushes and looks down, he can’t believe Kacchan read his thoughts so easily! 

“Heh, that’s what I thought.” 

“Shut up—”

“Would you be okay with us taking care of you when you’re little, ribbit?” Tsu’s cut-in sobers them both up instantly, focusing back on the overall conversation once again. 

“Yes,” Iuku says plainly. “I trust all of you with my life on the field, I don’t see why my littleself shouldn’t either. Hell, he trusted you enough to come out last night.”

“True,” Todoroki says aloud. 

There is another moment of silence, albeit not awkward like Izuku might have feared it would, now that the overall conclusion has been made. Izuku might have some more caregivers in the future, and he has to admit that he really does love the idea of it. So that he doesn’t have to suppress his own regression on nights when he knows Kacchan will be busy or at his work-study late, and also knowing that he can spread his time out with more than just one person. 

Denki is the one to pull Izuku out of his thoughts again, “so do you like… schedule these playdates with Baku, or do they just happen?”

“You dunce face,” Kacchan says immediately, “we already covered this!” 

“No, I know, I know!” Denki bites back, both of them still smiling. “I just meant like, can we—” his hand circles the air in front of him so that he gestures to everyone sitting at the table, “—schedule a time to play with him the next time he’s regressed, so we don’t all come at him at once and overwhelm him.” 

Izuku is grateful for Denki for a lot of reasons, but this is definitely at the forefront right now. “That’s so sweet,” he catches himself murmuring. 

“Oh, I know!” Uraraka is back to raising her hand in the air again. She speaks when they all look at her, “we could make a group chat! That way Bakugo, or even Deku can if he’s big enough to use his phone, can text when he’s little and we can figure it out right then and there.”

Izuku grins, a thrill of happiness and excitement sipping through him. He now understands the feeling everyone seem to be exhibiting when they all first sat down. At some point, they all talked about this and came up with a plan for Denki to ask him if they could talk because they all wanted to know more so that they could be there for him… Sometimes Izuku doesn’t realize how much he loves his friends and how much they love him right back. 

“Most of the time I text Kacchan when I feel myself slipping anyways, so that is a perfect idea, Uraraka!” 

They all start talking at once about which app they should have it on and who should create it. Izuku sits back and lets them. He still can’t believe how lucky this has turned out for him; to have so many people be not only willing but excited to care for him? 

Then Kacchan laughs suddenly, interrupting all conversations. 

“What?” Kirishima asks. 

“Be prepared to get some nicknames,” is all he says. 

Izuku knows what he means immediately and his cheeks flame up. 

“Wait, what?” Uraraka laughs, looking back and forth between Izuku and Kacchan. 

The blond smirks and leans back in his chair, pulling himself back far enough to balance on only two legs. “How do you think I got the name ‘Kacchan’?” 

“Wait, that came from him being regressed?” Denki asks. 

Izuku thunks his head forward onto his textbook, sighing dramatically. Oh, why did Kacchan have to tease him about this? He could have just let them figure it out on their own… not that he’s actually upset at the teasing, after all, it is all light-hearted. 

“No, that came from when we were actual children. But would you like to tell them why that is, Izuku?”

“No,” he laughs, thinking that Kacchan is incredibly cruel for this (he really isn’t, but Izuku isn’t sure if his cheeks will ever cool off). After a second he concedes and answers him anyway, still talking into his textbook and not looking at anyone, “it’s because I used to have a hard time pronouncing things when I was little. And especially names. So I gave him the nickname and it just stuck… so yeah, my littleself probably won’t call you by your actual name.” 

“Okay, that is cute. I wonder what mine will be,” Todoroki thinks out loud, then a split second remembers what Izuku had said earlier, “I’m sorry.” 

Izuku laughs at his tone along with some others, “I don’t have as much of an issue with the compliments now as I thought I would, just don’t do it all the time.”

They nod and agree to follow his first rule. It gives Izuku hope for the future. He isn’t sure how this will pan out but he kind of hopes it does soon. In fact, he’s kind of excited for the next time he regresses. 

Eventually, their conversation does end and they all part ways to do their own thing, but all of them hold a secret from the rest of their peers. That secret has a group chat called “Little’s Corner <3” on each of their phones and Izuku leaves with a full heart. 

[flying-cat]

I just thought of Izuku immediately shooting up in the hero rankings like a week after he becomes an active pro-hero again because everyone is so happy that he's back and Katsuki wants to be annoyed that Izuku ranked higher than him so quickly like he would've been, once upon a time, but he really can't be because this is what he worked eight years to see, and now he can finally compete with him again. So he sits in his apartment, TV on, watching Izuku try not to stutter his way through his first returning interview with fondness and pride, and thinks it's finally time to put some actual effort into climbing higher on the hero rankings.

(Not that being #1 is his priority anymore. He's just happy that he gets to fight alongside Izuku again, that they can compete with one another as equals, and that they can complete one another like two sides of the same coin. For the rest of their lives.)
