Chapter Text

Today was going as normal as it could be going, class 3A (with the exception of Izuku) bundled up on the couch watching some new movie that had came out. He was running a bit late, wanting to get some work done before heading down with the rest of his classmates. Once he was finished, he texted their group chat, just in case one of them were too focused on the movie to reply to his message.

Izuku 💬: Hey! Does anyone want anything from the convenience store while I go? I'll be with you guys when I'm back! 😊

He grabbed his key and some cash, throwing on a hoodie with some sweatpants for his quick evening store run. About 5 minutes later, his phone pinged with a message from the group chat.

Mina 💬: Zukuu! Can you bring some sodas and the white cheddar popcorn please?

Mina 💬: Also, bring me a snickers thx babes ❤️

Kacchan 💬: You need one of us to come with you?

Izuku 💬: No, I'm fine! Thanks guys

Kiri 💬: Be safe, bro!

He smiled to himself at the message, shaking his head and hearting the message. He was already on his way when they texted, but he was there now, picking out the snacks that were requested and a few additional things. After he paid for his things, wishing the cashier a good night. He gripped the bag tightly as he stepped out of the store. Once out, he stood there for a second, taking in the air and how peaceful the streets were at the moment.

He was so used to chaos and villains by this point, so it was nice to get away from his hero struggles. It was the middle of fall, so it was a little cooler outside, another nice change. He took a deep breath, the wind picking up a bit and flowing through his curls. He gathered himself, starting the walk back home.

Halfway home, there was some commotion he heard through an alleyway. He peered through, careful not to make his presence known. It was a father screaming at his daughter, the girl clearly scared and holding her hands together to her chest. The father was still going on, screaming about her making a scene in the restaurant. Izuku was conflicted, he didn't like what was in front of him, but from his years at UA this didn't seem like something he should interfere with, especially if no violence was inv- His train of thought cut off when he heard a loud slap with the sound of a body crashing.

The girl now on the floor, crying with her hand up to her cheek. Izuku rushed over, calling out to the father.

"Hey! Stop!"

The father looked shocked, clearly recognizing the aspiring hero. The girl looked even more terrified, shutting her eyes closed as she put herself in a fetal position. The father went to reach down for the girl, looking to get away from this situation. Izuku went to reach for her as well, not wanting this unstable bastard to get away with this innocent child, family or not.

There was a noise, and then a gasp. Next thing Izuku knew, his eyes were shut and his clothes were a little too loose and somehow things just seemed so much.. bigger? He looked around, the girl and dad were gone now and his bag was next to him. The bag, also somewhat bigger now. That's when he realized, he had been hit by a quirk. He doesn't really know what happened or how. Sighing to himself, he wondered how he could safely get home now. He was starting to feel the effects of the quirk, it was making his brain fuzzy. He'd have to note that down when he was himself again.. If he could ever return back to normal that was. While still in his right mind, he pulled his phone from his pocket, wanting to call the most sane out of his friends. He couldn't decide between Shoto or Katsuki to better handle this situation. He sighed, calling Bakugou's number. It rung a bit, then a click.

"What, Deku?" Bakugou barked on the other end of the call.

"Kacchan.. help. Near the car shop."

Katsuki was confused, looking towards his classmates with a raised eyebrow. He gave them a look, and it seems only two of them understood that look. 

"I'm comin'. Stay right there." 

The call clicked off, Eijiro and Shoto throwing their shoes on along with Katsuki. Shoto mumbled something to their classmates about meeting Izuku, not wanting anyone else to worry without reason. 

𓂃𓂃𓂃𓂃𓂃

On their way there, Bakugou was worried sick, as much as he'd hate to admit it. He was the one who heard Deku's voice, he was the one who heard the pitch and fear in it. Kirishima could sense he was off, he put his hand on his shoulder, giving him a soft smile and reassuring him that he's sure Izuku would be fine. Hopefully telling Bakugou this would ease his own worries..

Once they got near the car shop, they saw a small boy sitting on the curb with a bag in his lap. A crying small boy. It was Deku. The three glanced at each other, confused on what to do during this situation. Shoto slowly approached Izuku, stooping down face level to the boy.

"Hi, Izuku. Are you okay?" He kept a soft voice, reaching his hand out to Izuku. Izuku grabbed it.
"Sho.. there was a.. dad and girl.. and then a quirk. I feel weird.." Shoto just nodded along with what Izuku was saying.
"Let's get you home, we can figure out how to fix this in the morning with Aizawa and hopefully return you to normal."

He hauled Izuku up into his arms, grabbing the bag that he had in his lap and making his way back to Bakugou and Kirishima.

"He says he was hit by a quirk and there was a dad and a girl? I don't know. But let's just get him somewhere safe." Bakugou scowled hearing the explanation, poking Izuku's forehead.
"I told you to stay safe, nerd. Gettin' yourself into all kinds of trouble." Izuku pouted, putting his face into Todoroki's neck.
"Sorry, Kacchan.."

Katsuki felt himself blush a little, remembering that's exactly how he was when they were kids growing up together. Always calling out for his kacchan. It made him feel soft inside, he couldn't help the smile that formed on his face.
"It's fine." Was all he could muster to say. 

Kirishima chuckled, nudging Katsuki's shoulder. 
"Who knew you could be good with kids, bakubro!?"

There was screaming and some more laughter. Izuku was safe now, so maybe everything would be okay.

The group arrived back to their building soon after, Todoroki walking through the living room area with a sleeping Izuku in arms, Katsuki and Eijiro behind them. It's safe to say the rest of the group was confused, Katsuki just quickly muttered a 'I'll explain later.' to ease their concerns. Shoto carried him up to Izuku's room, placing him on the bed and putting the blanket over his body. 

The boys looked to eachother, Katuski on the edge of the bed, Eijiro in the desk chair and Shoto on the floor. They all spoke in a low volume.

"Okay, so.. What should we do?" Eijiro asked. Katsuki ran his hand through his hair.
"Okay, like half and half said, we'll tell the old man tomorrow, but for now we just have to let Deku rest. I don't wanna deal with a cranky kid. I'll stay here with him, you guys go on ahead."

Todoroki was a bit hesitant, giving Bakugou a confused look. "Are you sure you want to stay here with him? I mean.." Katsuki quickly cut him off, huffing a bit as he spoke. 

"It'll be fine. Me and Deku grew up together, so I know what kid him likes and doesn't like. Things are different now. I'll play nice." Todoroki and Kirishima gave eachother looks, then nodded, concluding it was alright. They exchanged goodnight's and soon the other two were out of the room and heading to their own. 

Katsuki looked down at the sleeping child beneath him, moving to the floor in front of Deku, propping himself up with his knees. He took in the sight of the boy, the way his chest moved up and down as he slept. His flushed cheeks, and the perfectly placed freckles on said cheeks. His long eyelashes and beautiful lips. Oh, the things he could do to those lips. He looked away, facepalming himself. Jesus Christ, he's a child right now. It wasn't right. But he liked Deku even when he wasn't a child, so it was fine right? Deku was still himself, and he was 18 now. So, it's fine. He's not some sick creep, they practically grew up together. He was doing everything to convince himself, and most importantly his morals and it worked. He put his hand on Deku's cheek, rubbing over his freckles with now hitched breaths. His hand practically being able to cover his whole face. He let his fingers wander, his thumb moving to his bottom lip. 

Something was stirring inside of him the longer he kept their skin touching and the longer he let his mind wander. His pants were suddenly tight, until he looked down to see his erection. He cursed himself, taking his hand off of Deku's face. He did mental gymnastics again, trying to convince himself on why this was okay, why it wasn't wrong for him to be hard over Deku right now. Because he had gotten hard because of Deku many.. many times. So, it'd be fine to relieve himself, after all he couldn't walk out of the room with a tent in his pants.

He nodded to himself, it was fine. So, he unzipped his pants, freeing his cock from his boxers and holding it in his hand. He gave it a few pumps, using his finger to touch Deku's lip again, carefully putting his thumb in his mouth to gather some of his saliva. He withdrew his finger, rubbing it on his cock, it wasn't much, but fuck it made him so much harder. Katsuki kept stroking himself, laying his head next to Deku's on the bed to get a closer look. His breathing picked up, his face close enough so Deku could feel his breath. He got a bit closer, he knew he was getting greedy, pushing his limits but he licked a small stripe up his lips. His cock was burning hot, but there was a click. He turned to find the source of the noise, and there was Eijiro in the doorway. Katsuki came, he came right then and there. He had just been caught, cock in hand and tongue on a kid's face. Eijiro stood there, eyes blown as he slowly walked out the room and closed the door behind him. Fuck.

Kirishima stood outside of the door, hand clenched on his chest as if he were gripping his heart. He took a heavy breath, steadying himself. What the fuck was that? He didn't know what to think, was Bakugou some sort of sick creep who preyed on children? Sure, everyone sees how he looks at Izuku but was that really justified right now? He had so many questions invading his brain, but the most important one was why did the sight make him so fucking hard? 

Before he could think much else, the door opened behind him, quickly closing and there stood Bakugou. He looked distressed, hair damp and clinging to his forehead from sweat. They stood there for a couple of seconds, no one saying anything. Katsuki took the bite and spoke first. 

"About what you saw.. I uh, fuck. Shitty h- Ei. I don't know what to say." The hallway was silent again, so silent it felt like you could hear each of their hearts thumping in their chest. Kirishima finally spoke.

"I get it man, I mean.. It's Izuku. Who wouldn't? What I'm trying to say is uh- I won't tell anyone, bro." Suddenly, it felt like a weight was lifted from Katsuki's heart. He was about to thank him, but then realized what he said. 'It's Izuku. Who wouldn't?' He shot him a look of confusion, but shrugged it off. As long as this whole scandal didn't get out, he didn't give a single fuck. Kirishima gave him a soft smile, grabbing Katsuki and hugging him tightly. Usual Ei.

"Ah- Fuck! Get off of me, red!"

𓂃𓂃𓂃𓂃𓂃

Izuku woke up, sitting up and stretching his, now little body. He rubbed his eyes, getting off of the bed one foot at time. Everything else felt normal except for the obvious difference in his size and obvious state of mind. He pitter-pattered down the hallway and to the lounge area. Kaminari, Hitoshi and Sero were already down there talking amongst themselves. They eventually noticed him standing there, Kaminari, being the extrovert he is was the first to call out to him, despite the confusion.

"Izuku! Come sit with us!" He patted the spot beside him and Hitoshi. Izuku obeyed, sitting next to the both of them. He was a little nervous with the sudden attention on him.

"Mm.. good morning." He said, his voice quieter than normal. Sero basically melted, looking to the other two. "Dudes! He's so freaking cute!" Izuku felt himself blush.

Hitoshi nodded along, being as stoic as he usually was. "He is, but don't yell. You'll probably frighten him." Denki playfully hushed him.
"So, Zu, how'd you sleep?" Denki asked with a smile. 

"I slept good.. thank you." They were all practically melting even more now, not wanting to show it, though. Hitoshi sighed, slumping back.
"So. Now, what about our little.. relief break?" The three of them had planned to smoke since no admin were currently in the building, until Izuku showed up that is. Denki, looks like something finally clicked, since it seemed as if he had forgot.

"Dude! You're so right. We can go up to our room, or Izuku can go back up to his.." Izuku pouted a bit, tugging on Shinsou's shirt, looking up at him with big green eyes. 
"It's okay.. I don't mind. I can stay, I'll be good." Shinsou looked down at him, raising an eyebrow and questioning the repercussions of all of this. He looked to the other two for some sort of backup or confirmation. Denki sent him a thumbs up. "See, man! He can stay. My mom smoked around me as a kid and I turned out fine. Afterall, it is Izuku and he'll be back to normal soon anyone so it won't cause any uh.. stunts." Shinsou rolled his eyes, sure he turned out 'fine', what a joke.
Sero nodded along. "Yeah, should be fine."

He was conflicted, but Denki did have a point (in the second half) he'd be back to normal soon, so it was fine. He shrugged, he had just better not get blamed for this. He started to roll his blunt, once all of the boring stuff was done he grabbed the lighter off of the couch, lighting his blunt and taking a deep puff. Soon after, it was being passed around between the three of them. Once it was back in Shinsou's hand, he felt a tug on his shirt and big green eyes peering up at him again.

"Can I try.. please 'Toshi?" He jumped a bit at the request. "Izuku, you're just a kid. This is hard stuff. I can't give you this." Izuku pouted, fidgeting with his fingers. Hitoshi sighed, taking another puff and grabbing the boy's face, blowing the smoke into his mouth. Just like a good boy, Izuku let it inside, sucking in the air and coughing after. Hitoshi doesn't know what came over him, or why he did that but it was pretty damn hot. He looked to Kaminari and Sero who sat there, jaws dropped at what they just witnessed. 
"Holy." Denki said

"Shit." Sero finished for him.
