cw: consensual izuku gangbang)
'Plus Ultra' is one of the most famous boy groups people know, with record-breaking songs and exhilarating concerts, but what fans really love to talk about is the size difference. Midoriya Izuku, the lead of+

the group, is far smaller than the other four in the group. He only reaches the chests of Bakugou Katsuki, Kirishima Eijirou, Todoroki Shouto, and Shinsou Hitoshi, and yet he's the most vibrant of them all, making even the more reserved members smile and matching the energy of +

the more outgoing members effortlessly. No one denies that he's the glue of the group, the best singer and the best dancer. He's front and centre in all of the dances, and seeing the tiny twink surrounded by the bigger members sparks a lot speculation amongst fans, especially +

when Plus Ultra is performing more sensual routines. The fancams of Izuku's cheeky grins, of his intent gaze and of the way he bites his lip are always accompanied by some other member's chest in the background, because even on the rare occasions that his outfit includes heels, +

he's /tiny/.
Izuku knows just what his fans think. Some of the headcanons are uncomfortable, not just because of the fact that real people are spectulating those sorts of things about him, but also because some of them are scarily /accurate/. He's not too worrried though, +

because it's not as if they'll ever find out, right?
Well, that's what he assumes, until the day they accidentally leave a stream running. They're streaming a dance practice of one of their latest songs for an upcoming concert, and as much as Izuku's proud of the song's pure +

/sex appeal/, something they've never fully captured before, he can't deny that the routine is really, /really/ difficult. Still, he's being watched, so he continues to push himself, dropping low into the split with his ass facing the camera as the other four drop into a low hip+

roll at the same time. He can see the chat blowing up, he can tell they're doing well, but all he can think is of move after move after move. As he slides up against Kacchan's body and then drops back against Eijirou's, he can feel himself start to fall behind a little, so he +

forces himself to work /harder/, only for Hitoshi to step out of the routine and stop the music. Izuku stumbles forward, not expecting the sudden stop, but Shouto swoops in and catches him in his arms.
"Thanks," Izuku says a little breathlessly, receiving a gentle nod in return.+

They turn to Hitoshi, who's yet to explained why he's stopped.
"Hey," he waves at the camera, addressing the fans. "I know we go Plus Ultra, but it looks like Deku-" Izuku's stage name "-is going a little /too/ Plus Ultra, so I think we'll take a break here. Stay tuned for +

another stream, and remember to tweet us at plusultra, okay?"
"Alrighty, we'll see you soon!" Eijirou joins in, heading forward to close the stream.
"See ya later, losers," Kacchan grins, and Shouto just waves. Once Eijirou gives the thumbs up that the stream has ended, Izuku +

immediately turns to Hitoshi.
"I'm so proud of you for saying all that!" he squeals. Hitoshi's always had issues with talking to the camera, preferring to observe in silence a little like Shouto, but he'd said all the right things. Hitoshi smiles at him and ruffles his hair as +

Shouto lets go of him.
"I had to," he shrugs, "I could see you were being stupid and pushing yourself too hard. You know that you need to save energy for the concert, right? If you get injured, it'll be harder on yourself."
"Yeah, dumbass," Kacchan retorts, "you need to tell us +

this shit."
"But it was going so well," Izuku whines, sinking to the floor.
"And it'll go even better if you look after yourself," Shouto reassures, sitting down cross-legged next to him.
"Yeah!" Eijirou pipes in. "You're doing well already, bro, you don't need to worry!" +

"Those splits especially," Kacchan muses. "They're hard, but they make your fat ass pop, so you need to practice those rather than rushing through them."
"Kacchan!" Izuku splutters, flustered. He knows just how much the others like his ass, but it's still something that has him +

blushing whenever they mention it.
"Mm, come to think of it, you did look delicious in that pose," Hitoshi says slowly. "We should help you /practice/ it sometime."
"But not right now," Shouto cuts in. "Right now, we need to be looking after Izuku."
He rests a hand on Izuku's +

inner thigh, making Izuku squirm a little.
"I've got an idea on how we could /look after him/," Kacchan says, walking up to him and threading a hand through his hair. Izuku looks up at him, blushing as if he doesn't know exactly what Kacchan means.
"Yeah, right," Hitoshi snorts +

sarcastically, "as if that's not gonna /wreck/ him."
"W-Well, sometimes if he's /physically/ taken care of, th-then his mentality will follow through!" Eijirou says, before frowning. "Does that make sense?"
"Izuku would you like us to make you feel better by fucking you?" Shouto+

asks blatantly. Izuku and Kacchan both splutter at the statement, but Eijirou and Hitoshi laugh at his frank speech.
Izuku gulps, looking around at them. It has been a while since the last time he'd had sex with /all/ of them... Everyone's been so busy with the upcoming concert,+

after all, so...
"U-Um, yes," Izuku mumbles. As soon as the words are out of his mouth, Shouto moves forward to kiss his lips, and Izuku reciprocates the kiss eagerly, clambering into Shouto's lap and straddling him. He grinds his ass against Shouto's growing erection, only for +

Kacchan to grab two handfuls of his big ass and yank him backwards forcefully. Izuku yelps as he falls with his nose buried in Shouto's clothed crotch.
"Better," Kacchan purrs, his hands kneading against Izuku's ass. "Fuck, these leggings are straining so hard over your ass, I +

wanna-"
"No," Izuku scolds, looking back, "no tearing them! You've ripped enough of my leggings!"
"Shame," Kacchan tuts, before hooking his fingers under the fabric of Izuku's pants and tugging them down quickly to force them over the round curve of his ass. His ass jiggles, and+

Eijirou marvels at it.
"You really do have a great ass, Izuku," he says sincerely, as Kacchan spreads his cheeks.
"What's /this/, Deku?" he teases, rubbing his finger against Izuku's leaking hole. "What's got you all stretched and lubed up? Is that /cum/?"
"H-Hitoshi fucked me +

before practice," Izuku confesses, his words muffled against Shouto's crotch.
"Quite bold of you to suggest resting then, considering you've already had your fill," Shouto murmurs. "Maybe we should leave you out of this."
"It's not my fault I caught Izuku feeling horny this +

morning," Hitoshi defends.
"Yeah well, I'm fucking the nerd's ass, and Shouto's taking his mouth, so where are you gonna fit?" Kacchan sneers.
"He can fit-"
"-more than one, you're right!" Eijirou interrupts. "So I'll be taking his ass too, if it's okay with him."
Izuku hums his+

(no tweet limit, u don't get to be part of the gangbang, go away)

agreement, his small dick hardening at the thought of it already.
"I-I can give you a handjob, Hitoshi," Izuku offers timidly. "Y-You can cum on my freckles, if that makes you feel better."
Both Hitoshi and Kacchan groan at that statement as Hitoshi nods.
"How the hell do you +

get so lucky when you've already tapped his ass?" Kacchan mutters. Izuku shakes his ass a little, making his ass cheeks clap the way that Kacchan likes it, just to cheer him up. But instead he gets a rough slap across his ass, making his ass jiggle more.
"Kacchan!" Izuku +

whimpers.
"Bro, don't spank him, he's behaving himself," Eijirou says, kneeling down next to Kacchan.
"He's been overworking himself and we're just pampering him," Kacchan huffs. "He deserves a little bit of a punishment."
"Don't listen to Katsuki," Shouto says calmly, tilting +

Izuku's chin up. "You're a very good boy. Are you ready?"
"Yessss," Izuku says eagerly, his hands reaching for the hem of Shouto's trousers. He pulls them down with Shouto's boxers to reveal Shouto's erection. Eijirou's got the girthiest cock, Hitoshi's cock has the best +

texture, and Kacchan's cock is the best combination of all the members, but Shouto's the one with the longest cock, and Izuku's mouth waters as it rests against his face. He licks the underside of it, before moving up to kitten lick the tip. Shouto lets him go at his own pace, +

but it seems that Kacchan's getting impatient, because Izuku doesn't get a single word of warning before Kacchan's /ramming/ his cock into his prepped hole, hitting his prostate on the first try. Izuku cries around around Shouto's cock, the force of the thrust pushing his mouth +

a little further down Shouto's cock. He doesn't even know when Kacchan got his cock out, let alone Hitoshi, but when he looks up, Hitoshi's stroking his dick to the sight of Izuku being spitroasted. He can't see Eijirou, but he's sure that Eijirou must be jerking off too by now.+

Izuku makes a grabby hand motion towards Hitoshi, and Hitoshi leans forward so that Izuku can start stroking his dick for him.
"Fuck, your hole's so /tight/, even though Hitoshi took the liberty of using your fat ass," Kacchan praises, his hand coming down to spank Izuku's ass +

in time with the thrusts. Izuku moans, spreading his legs wider as he bobs his mouth up and down on Shouto's cock, taking more and more of it into his mouth.
"Do you think he can take me now?" Eijirou asks Kacchan, to which Kacchan responds by spreading Izuku's ass cheeks again.+

"I'm sure our pretty little slut could take /more/ than two cocks right now if he wanted to," Kacchan croons, and Eijirou must take that as an invitation, because Izuku feels the tip of his thick cock pressing against his ass. It's okay though, because Eijirou always goes- +

Eijirou /slams/ into his hole at the same time as Kacchan, and Izuku's eyes widen as he moans loudly around Shouto's cock.
"I might as well join in," Shouto says pleasantly, before thrusting up and forcing his entire length into Izuku's mouth.
He's so stuffed that he can feel +

it in his belly and his throat, and tears spring to his eyes as Shouto starts to fuck his mouth. He slackens his jaw and twists his wrist as he jerks Hitoshi off faster, his ass jiggling wildly as Kacchan and Eijirou piston in and out of him. The tears spill down his face the +

same way drool spills down his chin and wettens Shouto's lap.
"Fuck, even a handjob from you is perfect, Izuku," Hitoshi pants, bucking his hips against him.
"Because he's our perfect baby boy," Shouto hums, his voice a little strained as he picks up the pace, shoving his dick +

down Izuku's throat over and over.
"He's our perfect little /whore/," Kacchan corrects, driving in particularly hard at the phrase. "Such a pretty fucking /cockslut/, bet he'd take even more if he fucking could."
"He's amazing, either way," Eijirou manages, one of his hands +

sinking into Izuku's supple ass. "His ass feels so good, and it looks delicious - I wanna take a bite of that round, fat ass, I wanna make him feel so /good/ the way he makes us feel-!"
"Fuck, getting ahead of yourself, are you?" Kacchan teases, grabbing one of Izuku's thick +

thighs and hosting it up so that he can fuck Izuku /deeper/. At the very same time, Hitoshi grips Izuku's hair and tilts his head back so that his plush lips tighten around Shouto's cock as he fucks his throat /harder/, and even though not a single one of them have touched +

Izuku's pathetic, quivering cock, they know they don't have to, because the combined sensation of all the members using his body has his eyes rolling back, a muffled scream escaping his mouth as he /orgasms/ hard. His whole body trembles as he cums against the floor, and Hitoshi+

calls out Izuku's name as he cums too, Izuku tilting his head as he continues to stroke so that Hitoshi splatters cum all over his freckles.
His hole clenches, and he feels Eijirou's nails dig into his fat ass as Eijirou tips over the edge too, filling Izuku's belly up with cum.+

But Kacchan and Shouto aren't done yet, Shouto still fucking his cum-covered his face with a desperate urgency and Kacchan still fucking his ass sloppily. Hitoshi and Eijirou both finds way to be useful too, Hitoshi's hands slipping under his shirt to play with his overly +

sensitive nipples and Eijirou's hand wrapping around to milk Izuku's overstimulated cock. His body feels hot all over, the sensations far too /strong/ for him to deal with, but all he can do is mewl around Shouto's big cock as Kacchan hammers against his prostate.
"Ohh, you look+

so /beautiful/, Izuku, I'm so close," Shouto makes out, hands tightening in Izuku's hair as he fucks him /harder/ and /harder/. Kacchan slaps his big ass even more roughly, grabbing another thick handful and jiggling it forcefully as he pounds him relentlessly.
"Fuuuck yeah, I'm+

gonna stuff your belly so fucking full of cum that you won't be able to move," Katsuki groans, slapping Izuku's ass again and again. "You'd like that, wouldn't you, you little /bitch/?"
"You're my perfect /princess/," Shouto says at the same time, and Izuku's throat constricts +

at the praise, his hole clenching tight at the degradation. The way he tightens around them /both/ sends them into a simultaneous orgasm, Katsuki pumping Izuku full of cum until his belly is bulging as Shouto fills his mouth with cum. They keep thrusting in and out, Hitoshi and +

Eijirou picking up their ministrations, and Izuku sees white as he cums /again/, screaming hoarsely at the overwhelming pleasure. They fuck him through his high, and when he comes down from it, they pull out carefully, Kacchan scooping him up and cradling him against his chest +

as the others pepper him in kisses. A short while later, Eijirou goes to pick up the tablet they were streaming from to check the time, only for him to drop it with a loud gasp.
"Guys," he says shakily as they all stare at him. "T-The stream didn't end. It's still running."
END.

OKAY this definitely isn't like anything I've ever written before, both character/content wise, but Anon hit me up with this idea and drew me some DELICIOUS ass expansion, so I just had to write it!
If it hit you in the kink, please consider tipping me🥺💕
