Work Text:
Izuku walks into the common rooms of the dorms and hears the attempts of hushed whispers from his classmates gossiping on the couch. It’s not like they need to be quiet, considering that secrets are quickly shared with everyone, but it does add a bit of dramatic effect when silence falls over the group as they stare at Izuku, who just came down to get a glass of water.
He can tell by their expression that they’re just dying for him to ask what they’re talking about.
“Uh,” Izuku starts, “what’s up, guys?”
“Ren Kuboyasu is courting Arisa Mitsuba!” Mina exclaims without any delay.
“Uh, who?”
“They’re both in the same first-year general studies class!” Hagakure quickly fills in, before leaning onto Ochako, sighing wistfully , “isn’t that so romantic ?”
“They seem a bit young, in my opinion,” Tokoyami says, holding one of Yaomomo’s tea cups.
“Don’t ruin it!” Hagakure wails, “I wish someone would court me . Serenade me in front of the school, bake me some homemade cookies, sneak me out of my room in the middle of the night-”
“You read too many romance mangas,” Tokoyami frowns, “You’re gonna disappoint yourself with expectations like that.”
Oh, they’re talking about romance . It’s not that Izuku doesn’t like romance, he enjoys occasionally hearing his friends dish about their own crushes, but he always feels a bit awkwards and guilty for talking about other’s affairs without their knowledge. He pours himself some water, hoping that if he stays quiet then he can sneak off back to his room.
“It’s not unrealistic!” Hagakure says, “ Midoriya gets those things!”
Izuku pauses, blinking as he processes what he just heard.
“ What? ” He squeaks, “What are you talking about?”
“Okay, well maybe Bakugou doesn’t serenade you or bake you cookies,” Hagakure quickly says, “But he cooks you food! And you both sneak out at night!”
Bakugou . Like Bakugou Katsuki. Like Bakugou “Kacchan” Katsuki. Like Izuku’s childhood friend turned rival Kacchan , who has never looked at Izuku with anything other than an unimpressed face, who constantly chastises him for being a clumsy and shitty nerd , who has known him since he was a child with a snotty nose and crybaby eyes. She's referring to that Bakugou.
“Me- what, huh ?” He sputters, “ Kacchan? Me and Kacchan ? I’m not- we’re not- he’s not courting me!”
“What?” Jirou says, face crumpling in confusion, “He’s not courting you?”
The words are so appalling to Izuku that he thinks his brain short circuits for a second. Courting is what you do when you like someone, and there is no way that Katsuki could like Izuku after all the shit he’s seen. He’s probably seen Izuku with broken bones and a busted, bloody nose more often than not, and who in their right mind could ever find someone attractive after seeing them in that state?
“Why would you think that?” Izuku asks in disbelief, feeling his palms starting to sweat, “Kacchan and I are just friends!”
“Then why do you guys leave the dorms so late at night?” Hagakure questions with a playful tone that he does not appreciate.
“We go out at night to train together, with Aizawa’s sensei’s permission too! We’re not sneaking off to- to- uh- ! ”
“Wow,” Jirou says, “I really thought you two had a thing going.”
“Well we don ’t.”
“That’s so weird,” Mina says thoughtfully, “Ki- I mean, someone was talking about wanting to court you, and Bakugou basically growled at him. We thought Bakugou was telling him to back off ‘cause you’re taken.”
“We- he-” Izuku sputters, trying to come out with an explanation. Our alpha is possessive over us , his inner omega says, pleased - much to Izuku’s annoyance, reminding himself that Kacchan is not our alpha , “He probably thinks romance is a distraction and doesn’t want to risk all our progress to become the top heroes!”
Mina frowns, “Is that what you really think?”
Well, it’s the most probable explanation.
“That’s such a shame,” Hagakure sighs, “I was so jealous of you guys too. An alpha and omega couple that are childhood friends? That’s to die for.”
Izuku can’t help the grimace on his face. It’s not that he blames his beta friend for being a bit disillusioned, knowing that most of the romance media on the market focuses on mostly omega and alpha relationships. And as a beta, she wouldn’t know that those kinds of stories tend to leave a bit of a sour taste in his mouth, though he can’t exactly criticize her for liking them so much. The occasional extremely sappy romcom with an omega and alpha pair is his guiltiest pleasure, once he’s able to look past all the more… problematic aspects (it’s easier to do so on the days leading up to his heat).
But it’s also that Katsuki doesn’t really… well, seem to recognize that Izuku is an omega. It’s not that he doesn’t remember , but gender doesn’t seem to be something that matters to him. Katsuki sees people as their strength on the battlefield, which Izuku - and many of the girls for that matter - greatly appreciates. But it does leave a bit of a disappointment in him when he realizes that Katsuki is an alpha that is highly fawned over, tall and handsome and strong , while Izuku isn’t like the image of what a stereotypical omega is supposed to be like, who are round and pretty and soft .
Not that he cares to be, his top priority is becoming a strong hero that people can depend on, and it’s evident in all the marks that cover his body, rough skin and puffed out scars from wounds that have healed over, and the new ones he gets almost every single day.
But still… sometimes he can’t quite silence his omega that yearns to have someone to depend on.
“Stop being weird about Midoriya secondary gender,” Tokoyami scolds, “It’s inappropriate.”
“Oh!” Hagakure says, “I didn’t- I didn’t mean it like that , Midoriya, I’m sorry!”
“It’s fine,” Izuku forces a strained smile, “I’m gonna, uh, go back to my room.”
Once he’s safely alone in the stairwell, he lets out a tired sigh. Though this whole conversation made Izuku want to sink into the floor, he’s glad that he was able to clear up this misconception, before it got out of hand.
Oh gosh, imagine if Katsuki heard about this. He shudders at the thought.
Izuku stands in front of the mirror, carefully placing the transparent scent patches over his glands, smoothing hand over them to avoid any wrinkles before moving on to apply the next one. It’s a tedious routine that he has to do before changing into his suit, but it's required by law that heroes have to cover up their scents while they're on the job.
It doesn’t bother him too much, Izuku is used to the boring, repetitive motions of applying his scent patches. Even when he’s not interning he still prefers to remain scentless, especially since Yuuei is a school filled with mostly alphas and betas, and as an omega he tries to avoid any accosting that could happen to him because of his scent.
He doesn’t feel as if he’s at a disadvantage in any way because of his gender, but he knows that he was lucky to have received a strong quirk like All for One that helped him gain admission into Yuuei. Most of the other omega at the school tends to be in general studies, with a select few in the support courses. Izuku, however, is the only omega in the hero course, and he is very conscious of that fact.
Especially when he catches Shoto staring at his body while he’s changing into his suit, stepping his feet into the legs one at a time before pulling it up to his waist, eyes widening in a bit of shock and confusion as the boys have an impromptu staring contest. If it were any other alpha, then Izuku would feel a bit worried, but since it’s Shoto, the most Izuku feels is awkward .
Shoto is already dressed, and they’re standing in the locker room at the Endeavour Agency, ready to go out on patrol with some of the sidekicks. Bakugou finished changing first, as he normally does, and promptly left as soon as possible, despite them still having ten minutes before the trio is expected. Shoto stayed back with Izuku, knowing that the second he leaves he’ll be hounded by his father. Endeavor would normally also be kicking down the door to his locker and room looking for his son, but he tends to stay away from there whenever Izuku is inside.
It’s a bit… traditionalist of him, since the other male sidekicks don’t seem to have a problem changing with someone of a different secondary gender, but not necessarily in a bad way. Endeavor has even offered to build Izuku his own locker room for more privacy (technically he just offered to build one for omegas specifically, but Izuku is the only omega hero in the building), to which Izuku politefully - and embarrassingly - declined.
While the older Todoroki is very mindful of Izuku’s secondary gender, the younger Todoroki doesn’t seem to notice it at all, which often gets them stuck in awkward moments like these where the alpha doesn’t seem to understand the nuances and grace needed when hanging around an omega. Where he is blatantly staring at a half-naked omega, as he gets dressed.
Finally, Shoto breaks the silence, “What’s that on your back? I’ve never noticed it before.”
Izuku immediately looks over his shoulder, down his bare back before he realizes what his friend is referring to.
“Oh,” Izuku laughs, full of air and relief, “It’s a hormone inhibitor.”
Shoto blinks a few times, face blank as it usually is, “Inhibitor?”
“Yeah,” Izuku confirms, sliding his arms into his sleeves before zipping up the suit, “It’s, uh, it’s a bit stronger than the suppression pills are. It’s a little machine device that gets attached to your skin, and it injects a steady flow of enzymes that, well, inhibit hormones. I used to wear it on my thighs but I always broke it accidentally whenever I used shoot style.”
“That sounds painful,” Todoroki frowns.
“Not at all!” Izuku assures, “Well, putting in the device itself kinda hurts, but it’s usually a one and done kinda thing. I just have to replace the pods that have the inhibitor medicine whenever they run out.”
“Oh,” Shoto nods in understanding, “How come the rest of us don’t have one?”
“Uh…” Izuku puts his gloves on, flexing his fingers in the snug fabric, before looking over at Todoroki. He doesn’t know how many people know the inhibitors even exist - save for All Might, obviously, and Katsuki, who asked about it once before, “It’s for omega heroes.”
“Oh,” Shoto repeats.
“Yeah,” Izuku says, lacing up his shoes. Then he volunteers, “It- uh, stops me from being able to smell pheromones so I can, um, avoid falling under a command. From an alpha. If it ever happens. Not that I think anyone would! I know how it’s illegal and all - but if it’s, you know, a villain , who is already doing other illegal things, then they might…” he gestures weirdly to himself, “... yeah .”
“It would be despicable of an alpha to do something like that,” Shoto says seriously, as the boys make their way out.
“Yeah, of course,” Izuku agrees, “But… you know… there’s a reason why it had to be written as a law that it’s illegal to use commands without the consent of the omega’s, or even beta’s - it depends how strong the alpha’s pheromones are, but I heard of cases of where even betas can be affected by commands if it’s really strong - but I wonder how that could even be measured? It must be a mix of things, it’s not like an alpha could go up to any beta and have them be affected by their commands - betas still get affected by scent though, so maybe if the alpha’s pheromones are really, really strong then it could sway the beta’s biology towards to other side, but prime alphas like that are really rare .”
“My sister’s a beta,” Shoto says as they round a corner, “I don’t think she’s ever said anything about an alpha’s scent affecting her like that.”
“Well it would be really rare-”
“Oi!” A familiar voice interrupts, rough and gravelly, “How long were you nerds planning on making me wait?”
Izuku freezes, turning his head to see Katsuki standing by the entrance, arms crossed over his chest. He’s back in his summer uniform as the spring season starts to become warmer and warmer, muscles biceps on full display, the cut of his tank dipping into his prominent pectoral muscles. His blond hair sticks all over the place, but it looks messy in a purposeful way, falling over his forehead, covering the top of his mask. His ruby eyes gleam with annoyance, lips pulled into his signature scowl.
He looks like how Katsuki normally does, but Izuku doesn't ever think he’ll be prepared for it.
“We aren’t late,” Shoto informs him, glancing at the clock hanging over the door, “Burnin isn’t even here yet.”
Katsuki clicks his tongue, and Izuku laughs nervously, glancing between the two alphas.
Katsuki and Shoto always seem to be having a petty argument of some sort, though the latter is always completely oblivious to it. Izuku finds their relationship to be like a breath of fresh air - even though Katsuki has considerably mellowed out since his first year at Yuuei, he still tends to butt heads with everyone else due to his ornery personality and short fuse for his patience.
But with Shoto, even though Katsuki vehemently denies that they’re friends - as he does with all his classmates - the dual user simply refuses to label them as anything else. (Shoto has told Izuku once that he thinks he and Katsuki are working their way towards the title of best friends , considering how much time they’ve been spending together sparring, and Izuku doesn’t have the heart to be anything other than supportive of Shoto’s conclusions).
Izuku notices the way Katsuki’s eyes seem to be locked onto his figure, and Izuku can’t help but get lost in his gaze, staring into eyes bright like a red star, almost dancing with solar flares. Izuku always tends to feel small in Katsuki’s presence, and it’s not necessarily because he’s an alpha, but because he’s freaking tall . Izuku’s not short by any means, he’s even on the tall side for male omegas, but he still only reaches up to the blond’s shoulders, and that’s when Katsuki’s walking around with hunched shoulders.
Though it’s stupid, his inner omega tends to fantasize about what it’s be like to have a strong alpha like Katsuki, and it doesn’t help that Izuku himself has a candlelight of a crush on Katsuki that’s been burning wax since they were children. Even though it seems at first glance that Katsuki acts like a typical egotistical alpha, Izuku knows that’s not the case at all. Even though he struggles here and there with low self-esteem, he still respects himself enough to never find himself attractive to a cocky, sexist alpha. It’s more accurate to say that Katsuki is just battling a severe case of teenage angst, and that’s something Izuku doesn’t have a problem with.
Even when Katsuki sneers, Izuku can’t help but feel a bit of attraction bubble inside of him, still thinking that the blond is the most handsome person in the world ( objectively speaking though, the prettiest person Izuku knows would probably be… Shoto, or maybe Mina, but subjectively there’s no competition, Katsuki takes the cake). Katsuki is still a bit scary and rude, obviously , but despite the fact he looks three seconds away from murder at any given time, Izuku still think he looks… cute. Like how a pug looks cute - ugly, but in an endearing way.
Izuku realizes everytime he becomes aware of his own heartbeat in Katsuki’s presence that he must be a real masochist , falling for someone who has no interest in him. He tries to convince himself that it’s just a harmless childhood puppy-crush, but with every year that passes and the boys become more mature, Izuku’s crush becomes less and less innocent.
“Hey boys!”
Izuku turns and sees Burnin walking towards them, green flames crackling behind her, waving and grinning at the trio. Izuku and Shoto greet her back, and Katsuki stays silent as he watches her, though at least it’s not an annoyed tch . A nonverbal greeting is the closest to a happy greeting that someone can get from Katsuki.
“Do you guys have your bracelets?” Burnin asks.
“Yup,” Shoto says, lifting his arm to show the bracelet around his wrist.
It’s technically called a Hero Watch , though the band is thin and compact, and the design is so minimalist that it makes it look like a bracelet. It’s supposed to work as a tracker and and has a button on the side that can trigger a distress signal to the closest agencies and the one the hero themself work at in case of any emergency.
Izuku nods, resting his hand on one of the holders on his utility belt where he keeps his Hero Watch. He finds it uncomfortable for him to wear underneath his air force gloves, and though it’s supposed to be almost indestructible, he doesn’t wanna test out to see whether it can withstand the recoil from an OFA punch.
“Alright!” Burnin grins, “Let’s go!”
The group ends up splitting up into teams of two to cover their patrol area, and naturally the Wonder Duo pair off together. It’s more accurate to say that Katsuki walked off with his heavy steeps against the sidewalk, before turning his head and barking hurry up, ya damn nerd!
It’s a mostly uneventful patrol, with just walking around the neighborhood and stopping to chat with some store owners that they’ve made acquaintances with from seeing so often, and occasionally stopping to entertain the children that run up to them all excited to be in the presence of a hero. Though Deku is the friendlier one who juggles their small bodies (with their parent’s permission, of course), Katsuki also tends to get dog-piled with energetic kids who think that his off-putting attitude makes him so cool , and when he lets off a few sparks there’s no tearing them off his gauntlets.
“I didn’t know you liked kids so much,” Izuku teases once the parents walked away with their children.
“I don’t ,” Katsuki grunts.
“Well they seem to like you,” Izuku sing-songs, “They must think Kacchan is amazing.”
Katsuki snorts, “Think you’re projecting a little bit there, nerd.”
“What?” Deku squeaks, “no I’m not!”
“Oh yeah?” Katsuki challenges, a mean smirk on his face, “I only know one shitty fanboy who runs around saying ‘ Kacchan is amazing’ .”
“I don’t say that!” Anymore . Not out loud , anyways.
Surprisingly, Katsuki doesn’t continue his antagonism, “Right,” he says, looking down to the end of the street. “Of course.”
Izuku frowns. It’s not that he necessarily likes having small arguments with Kacchan, but that’s just a part of who Katsuki is. And when the blond starts pulling back his verbal punches, Izuku can’t help but feel as if they’re not close enough to have that sort of banter. Though he knows they have a complicated history, and they’re both just trying to navigate their budding friendship, it doesn’t stop Izuku from wanting to tell Katsuki to just treat him like Kirishima or Kaminari, or even Shoto .
Being on the receiving end of an explosion is deadly, but Izuku thinks it’d be more satisfying than a cut fuse.
“We should head back,” Katsuki says, and then grumbles, “The Icyhot bastard is probably missing you.”
That makes Izuku frown harder , wondering what Katsuki is talking about.
‘Ki- I mean, someone was talking about wanting to court you, and Bakugou basically growled at him. We thought Bakugou was telling him to back off ‘cause you’re taken.’
He bites his lips, wondering why he’s thinking about Mina’s words now . He’s being silly, there’s no way that Katsuki is… jealous of Shoto, right? That makes Izuku want to laugh at himself for even thinking that could be the case.
“Shoto isn’t-” Izuku starts to say, but gets cut off when he sees something shifting out of the corner of his eye, a chill running down his spine.
Turning around he sees nothing except an empty street, but he could’ve sworn he saw someone behind him, felt the presence of something heavy there. There’s a weight in his chest when he sees a dark alley in between two buildings, a strange instinctual pull of a hero that tells him to go.
“Kacchan, do you smell anyone?” Izuku asks. The lack of being able to smell was one of the sacrifices Izuku had to make with his inhibitor, but most people just wear scent patches anyway.
“Hah?” Katsuki pauses before answering, “Not anyone particularly close, why?”
But the shadow is calling out to him. He takes slow steps, and Katsuki follows behind. He tries to calm his heart, but it beats rapidly like it did when he first met Eri, when he first laid eyes on Chisaki, the alley reminds him of the darkness they went back to. He’s not as inexperienced as he once was, but he can’t help but always feel scared just the same.
They stop at the alleyway and there’s a couple of overflowing garbage cans at the back, near the brick wall covered in graffiti, no one in sight.
“What’re you doing?” Katsuki asks when Izuku takes a step inside.
“I don’t know,” he murmurs, as Katsuki still walks behind him, “I feel like there’s- there’s someone .”
“What?” Katsuki lifts his arms, curling his fingers, “Where they fuck are they then?”
“ Behind you. ”
Katsuki and Izuku whip around, explosions popping and lightning crackling from them respectively, as they come face to face with a tall man wearing a ski mask, who seems to have appeared out of nowhere.
“ Fucker! ” Katsuki yells, charging at the man. He tries to let off an explosion but the man sinks into the ground below, disappearing without a trace in the concrete.
“What the fuck ,” Katsuki growls, the boys looking around, “Who the hell was that shady fucker?”
He doesn’t get an answer, because the very next moment, the boys sink into the ground too, swallowed by the darkness.
When Izuku comes to, that’s a painful throbbing in his head. He opens his eyes and doesn’t find himself in darkness, but the flickering light that barely fills up the room is creepier . He tries to move but he can’t, the stiffness of his body and cotton in his head makes him let out a low, muffled groan. He can distantly hear the sounds of a chain rattling wildly, and furious snarling.
“Hey, he’s finally awake!”
Izuku feels hands gripping into his hair before yanking up, forcing him to look at his captor. There’s a bit of haziness in his vision, but he can see the sadistic smirk on the man clearly, all his teeth pointed sharp like canines. Izuku feels his stomach drop at the sight and he tries to struggle away to no avail, quickly realizing that his hands seem to be bound behind a beam, and his legs are tied together with a rope. He tries to activate OFA in a panic but feels a stinging on his wrist when he does, and he realizes he must be wearing quirk-cancelling handcuffs.
The man lets go of his hair and his head falls forwards, feeling fatigue all through his body. Lifting his neck up, the back of his head hits against the beam, as the man presses a finger directly onto the scent gland on Izuku’s neck.
“So you’re the omega hero we’ve been hearing about?” The man says, voice scratchy and hoarse in the worst way. “ Wow, I can already tell you’re gonna fetch me a pretty penny.”
He turns to a man behind him that Izuku didn’t notice before, who seems to almost blend in with the grey wall, “His scent is even better than I thought, it might make up for how fucked up his body is.”
“I wouldn’t worry about it too much,” the other man replies, brushing his black bangs out of his face. “He’s still got a nice ass and hips, if you lock him up for a bit he’ll lose all the unnecessary muscle.” Then he snickers, “Get him pregnant and it’ll happen even quicker.”
Izuku whimpers around the cloth gag in mouth, cold and wet with the drool, digging into the corners of his lips. He hears an angry roar, managing to turn to his head to see Kacchan a few feet away, similarly bound but thrashing against the restraints, howling as his face turns more and more red in anger. Izuku can’t smell him, but he sees the way his captor’s face scrunches up in disgust, and it doesn’t take a genius to figure out that Katsuki is enraged.
Alpha , his omega calls out, need our alpha .
“Damn, he’s a real noisy one,” the man in front of him complains, as if Katsuki is causing an inconvenience to them. He turns back to Izuku, “You smell so fucking good , omega, I can hardly hold back - you don’t mind if I have a taste, right?”
“Fuck, I kinda want a turn too. I bet he’s a real knotwhore - all the innocent looking ones are.”
Izuku can feel the tears instantly fall out of his eyes, a primal fear awakening within him. A sickening panic erupts in his body, his hands struggling against the cuffs, trying to break out and get away . His heart drums in his ears and his veins fill up with adrenaline, but all the energy is contained within his body - he can’t move , all he can do is pathetically shift around and whimper in an attempt to fight.
Don’t fight , his omega says, though it sounds pained, you’ll make it worse. If you submit it’ll be over with quickly, if you fight he will make it hurt .
He knows deep down that his omega is only trying to protect them from any unnecessary harm, but it makes Izuku spiteful , resenting the voice that tells him to freeze instead of fight , he wants to fight and roar and rage . In his hardly lucid state, however, he has a harder time fighting back against his omega, who works best with his primal instincts, not his rational mind.
He’s stuck, left to cry as the man leans over more and more. He looks over at Katsuki for some reason, his eyes filled with regret and heartache that he hopes he can convey.
Help us , his omega cries in a last attempt, help me, Kacchan .
And before Izuku can comprehend what’s happening he hears a loud howl, the sounds of a chain rattling before it snaps , and Katsuki arms come in front of him as he lets off an explosion.
It all happens too quickly, and then everything seems to go in slow motion. Izuku thought he saw the white flash of an explosion, but when he blinks his eyes open he’s in almost darkness. He’s barely able to blink his eyes open, limbs moving sluggishly as he tries to get up, and he realizes he's still restrained.
No - not restrained. Izuku is being held by someone, strong arms wrapping around his body, one large hand at his waist and the other pushing his head against firm pecs, his legs around their waist as he sits in their lap. He hears a deep, gravelly rumble vibrating from their chest, and he realizes he’s being held by Kacchan.
He takes a deep inhale and is instantly hit with the scent of what he can only describe as alpha . The rich scent of raging fire and caramelized sugar hits through his senses, and the underlying headiness of protect, protect, protect makes Izuku unconsciously start purring back weakly, too lethargic to fight back against his omegan instincts.
Safe, safe, safe. Safe with our alpha. Alpha will protect us.
“Deku?” Katsuki says once he hears the gentle purr, moving his hand from Izuku’s neck to his face, carefully pulling Izuku back so they can look at each other.
Izuku feels a warmth burst through him at every place Katsuki is touching, heat slowly seeping through his body, in a way that becomes increasingly alarming as the ringing through his ear disappears, but the fuzziness persists in his head and seems to start travelling through the rest of his nerves.
His mouth feels full of saliva, tongue thick and gently passing over his teeth. Izuku stares at Kacchan, blond spikes tousled and stuck to his sweat damp forehead, pupils dilated and almost shaky as he looks at Izuku in concern.
“What happened?” Izuku manages to ask, though he’s slurring his words.
“I’m sorry,” Kacchan breathes out to the few inches in between their faces, “I-I fucking- fuck, I don’t even know, I just- I just fucking-”
There’s a hint of distress that Izuku didn’t pick up on before, though now it’s bleeding through with a quiet shriek. Izuku takes deep inhales, relishing in the way his lungs fill up with Katsuki’s scent, but there’s a distant voice in his rational mind that tries to tell him that he should be concerned, and not just because they’re stuck in the darkness after an explosion.
“They tried to touch you and I just- you smelled so scared and I-” Katsuki stumbles over his words, which is completely unlike him, as if he’s trying to dance around the words but there’s no other way to say it. “I didn’t even have a chance to think about it, Deku, I just- I just couldn’t let them .”
Alpha protected us. Alpha protects us .
There’s a syrupy need that’s starting to pass through Izuku at that thought, a welcome warmth that he leans into more and more as he breathes in sweet smoke and nitroglycerin, the calming scent of his alpha.
Izuku starts to feel embarrassed as he realizes that Katsuki isn’t his alpha, but his omega cries at the thought of acknowledging that, especially when Izuku is safe in Katsuki’s arms and his scent and purr is like a nostalgic lullaby that comforts him immediately.
Kacchan’s scent ... Izuku thinks, before realizing that he shouldn’t be able to smell Katsuki.
Izuku reaches over to the left side of his lower back, over the fabric of his hero suit, and winces at the sharp pain he feels where his inhibitor should be, fingers almost cutting over jagged plastic if not for his clothes, the pieces crumbling to his touch.
It’s broken, Izuku realizes. His inhibitor is broken. Probably smashed when his body hit the concrete after the explosion.
Oh.
Oh no .
And the puzzles slowly start falling into place; Izuku realizes that he recognizes the hot pulsing in his body, knowing exactly what he’s headed towards. He isn’t supposed to be having his heat for another month - but he’s still young, his omega is immature and easily pliable, and sitting in the safe arms of an alpha he’s known all his life, inhaling the scent that brings a waves of security and comfort over his sense and is like a sweet spice on his tongue, Izuku can’t help but bloom for Katsuki.
Izuku pulls away from Katsuki’s chest, though his omega yells at him to stay subdued, the rational parts of his brain still tell him that they’re trapped, potentially still with the villains that kidnapped them. He looks around, there’s a flashlight that Katsuki has propped up, the beam hitting the ceiling and filling the space in a bit of light, dust and dirt particles floating in the air around them. Izuku realizes that they’re in some sort of safety pocket, where the building has collapsed all around them, encasing the two boys in concrete slabs and exposed beams.
“I couldn’t get us out,” Katsuki mumbles, embarrassed, “I- I don’t know how the damages are above us and you were knocked out. Didn’t wanna… risk anything.”
That comes as a surprise to Izuku, fully expecting the hot-headed blond to try and explode a path out of here. Although it would be unfair to Katsuki for Izuku to assume that he’s just a careless risk taker. No, Katsuki knows what he can do - which just happens to be more than most can - and his confidence is well-earned.
But it’s the fact that Katsuki is implying that he didn’t try to bring the building down more because… because he was worried about Izuku. He shakes his head and tries to fight off the blushy feeling he gets at that though, but it’s hard when the target of his affection for most of his life is cradling him and acting uncharacteristically gentle.
“Where are-” Izuku tries to clear his throat, “what happened to… to the people who, uh, took us?”
Katsuki’s silent, looking off at the parameters of their small enclosure. “I dunno,” he eventually mumbles, and they both sit in the heaviness of what those words could potentially mean.
“Oh.”
“Are you okay?” Katsuki asks, “I had to use your bracelet ‘cause mine broke, but I already sent out an SOS signal, so hopefully someone will come find us soon but…” Katsuki pauses, taking a deep breath, his mouth falling open as he shakily exhales, “You smell… you smell different .”
Izuku realizes exactly what it is Katsuki is smelling, his usual scent of fresh rain on warm earth and pine trees starting to shift to something more delicious, to the nectarous sweetness of ripe fruits and wildflowers blooming in the forests on balmy spring days. Usually there would only be hints of this scent peeking through on the days when his pre-heat started, but it never becomes overtly fragrant before Izuku could lock himself in his room for his heat days.
And obviously Katsuki wouldn’t have a clue what to make of this smell - but from the way his body seems to be reacting, his alpha seems to know.
“The inhibitor broke,” Izuku says, not meaning to speak in a whisper, but their faces are just so close together and it makes him nervous, “I think… I think my heat is starting early.”
Katsuki's eyes widen in realization, “S’your pre-heat smell...” he drawls, “ Fuck , was it always this strong ?”
Izuku shakes his head miserably, “No… I’m… I’m going into heat.”
“ What? ” Katsuki tries to recoil as much as he can, “What the fuck , Deku? Why the fuck didn’t you already go on leave?!”
“It’s not me-” Izuku’s breaths start to become heavier in his chest, feeling the familiar ache start to form in his gut, the sinking of a heavy stone through the surface of a pond.
“What do you mean it’s not you ? Did Endeavour fucking force you to work during your pre-heat? I’ll fucking kill that bastard-”
“No,” Izuku cuts him off, “It’s you- it’s for you ,” he says, forcing his mouth to move around his heavy tongue.
Katsuki can only manage to stare at Izuku in shock, processing the implication of the omega’s statement.
“It’s for… me?”
Izuku nods.
“You bloomed for me?” Katsuki breathes.
He nods again.
“You bloomed for me ?” He repeats for confirmation, voice almost tortured.
“I’m sorry,” Izuku whimpers, forcing himself to push off of Katsuki, a sickening swirl passes through him as his omega cries at the rejection.
Our alpha , his omega wails, stay with our alpha .
Not our alpha, Izuku thinks bitterly, as the thick pull of need begins to make him clench in his pants, cock twitching in response, “I’ll- I’ll stay away,” he tries to say, though the farthest he can go is only a few feet.
“Fuck, no- ”
Izuku gasps as he’s pulled back into Katsuki arms, a cloud of soothing pheromones pumping out from Katsuki in response to Izuku’s distress. And Izuku can see the way Katsuki’s body starts reacting to him, his dark pupils eclipsing the vermilion of his eyes, the alpha’s scent thickening and Izuku can practically taste it in his mouth, the surge of hormones in an instinctive reply to Izuku’s call.
The tension pulses between them as Katsuki grips into Izuku’s body, letting out a soothing purr upon hearing Izuku’s whimpers. The omega feels the thick dew of slick start to dampen in between his legs, his hips scooting down Katsuki’s thighs as their cocks tent in their pants.
“I didn’t- fuck , Deku,” Katsuki chokes out, “I don’t- I didn’t want to take you like this-”
His alpha, however, is screaming in his head, begging Katsuki to claim his omega, pick the fruits that have ripened, sink his canines into the taut skin and taste the nectar flow through his mouth. He cups Izuku’s face and watches in a morbid fascination as the omega’s pupils begin to expand until there’s hardly a trace of bright green left, his mouth hanging open and letting out hot breaths as he sinks into his heat.
Our omega needs us, his alpha snarls, needs us now .
Izuku nuzzles into his palm, face overheating and flushed, swallowing down the excess drool pooling in his mouth.
“Kacchan,” Izuku whines softly, “ Alpha .”
“ Fuck ,” Katsuki groans, burying Izuku’s face into the scent gland on his neck, scenting the top of the omega’s head with his cheek.
Izuku can’t help but be a slave to his instincts, hating the way his hormones reduce him to something desperate, vulnerable, and downright stupid . He laves over Katsuki’s neck, savouring the heady taste of sweat mixed in with the alpha’s blissful scent, his teeth gently nipping but not breaking the skin. He whimpers into Katsuki’s body, painful sounds of begging at Katsuki’s hesitation that his rational mind knows is fucked up , but his omega is starting to take over and is doing everything it can to tempt Katsuki to break his restraint.
“I’m sorry, Kacchan,” Izuku cries, “I’m sorry for doing this to you, I’m sorry, Kacchan-”
“ Don’t, ” Katsuki's voice drops and it makes Izuku’s body tense, that singular word slicing through his heart. But he continues, “Don’t fucking apologize, Deku, this isn’t about you , this is- this is about me .”
“You?” Izuku swipes his tongue over his dry lips, watching how Katsuki eyes shut, brows furrowing, before he forces them back open.
“This- fuck ,” Katsuki curses. “This is my fault - my scent’s the one that sending you into a heat against your fucking will and I just- Jesus, fuck, I wanted to do this properly .”
Izuku blinks, trying to desperately hold onto his last piece of sanity, hating the way Katsuki looks so pained, “What’re you talking about?”
“I shouldn’t have been so careless, holding you like this, this close,” Katsuki continues, “I couldn’t help it, Deku, I- fuck, fuck , you smelled how much I fucking want you and now-”
“Kacchan,” Deku interrupts, starting to slowly understand what Katsuki’s rationale is. But that would mean… that would mean that Katsuki likes Izuku, that Katsuki thinks the omega could smell how protective and enamoured the alpha is, sending him into heat against his will. And while technically, it is against his will, it’s not in the way Katsuki is picturing.
How goddamn far does someone have to reach to come to that conclusion?
“It’s for you,” Izuku says.
“Yeah, I know -”
Izuku shakes his head, “Kacchan, it’s for you . You’re the one… you’re the one I like- I’ve always liked.”
“What?” Katsuki almost yells, “ Why? ”
“What do you mean why? ” Izuku says, trying not to sound exasperated but he is trying really hard to fight back against his heat, and Katsuki thinking that Izuku didn’t like him is not the problem Izuku thought he would have.
Just present yourself , his omega tries to convince, he won’t be able to resist .
Izuku pointedly ignores that advice. Stupid, stupid omega brain.
“After- after all I’ve fucking done to you?” Katsuki whisper-shouts, “You liked me after all the shit I put you through?”
“Well, I never said I liked all the shit you’ve done to me,” Izuku grumbles, trying to solve all this miscommunication so he can convince Katsuki to fucking knot him already - no, no, that’s not the end goal here. The end goal is… is…
Izuku’s brain is so heat muddled he doesn’t even know what he wants. He wants to bite Katsuki all over, into every inch of corded muscles and skin candied with sweat. He wants Katsuki to do the exact same to him, letting them dissolve into a mess of carnal desire and animalistic need.
He just wants his alpha. He just wants his Kacchan .
“I… I want you,” Izuku manages to say, “It’s always gonna be you , Kacchan, you’re always gonna be the alpha- you’re always gonna be the person I want.”
“You should hate me,” Katsuki says, though he doesn’t sound like he wants that.
“I could never hate you,” Izuku instantly replies.
He can see the way Katsuki is warring with himself right now, and Izuku is only a few seconds away from descending into madness.
“I need you , Kacchan, please , I need my alpha .”
And the rope that Izuku was holding onto pulls so hard that it snaps , and the omega instantly collapses against Katsuki, body burning unbearably hot as his heat starts to prickle under his skin.
“ Shit ,” Katsuki says sharply, before nosing along Izuku’s curls, trying to calm the omega, “Okay- okay , it’s okay. I’m here.”
And while Izuku is mortified for falling into this state, weak and delirious before his alpha, Katsuki is downright terrified that he’s the one in control, not wanting to make the wrong move and hurt his omega.
“Tell me what you need,” Katsuki murmurs, swallowing thickly and fuck - are his teeth getting sharper? He knows it happens during his ruts, but it’s not like he notices it - brain too drunk on lust and biting desperately into his pillow as he fucks into his rut-aid, wishing that the cotton and feathers were Izuku. It’s weird, his body surging with hormones but still able to think with clarity, hyper aware of every movement in the space.
“Want you ,” Izuku whines, eyes watering because everything hurts so bad and he needs Katsuki to make it stop.
“I know baby, I know.” Katsuki runs wide hands over Izuku’s body, palms sweating and he has to make a conscious effort to not set off an accidental explosion - if he burns his omega he will take a fucking swan dive off the roof, Jesus fuck. “How- how far can I go?”
“Kn- Knot me ,” Izuku pants, “need your knot, Kacchan, alpha .”
“Okay- okay ,” Katsuki swallows thickly, holding Izuku’s head and pulling him back, staring into his heat seeping onto his features - half lidded eyes, cheeks like overripe peaches, mouth hanging open and lips shiny and slick with his drool. His eyes bore into Izuku’s, sharp and serious, but face still earnest, caring , “I’ll take care of you, Izuku.”
Katsuki leans forward slowly, and Izuku’s eyes flutter shut as their lips press together. It’s… soft , doesn’t feel much other than skin touching skin, but a fire erupts in Katsuki’s face and chest at the gentle intimacy. Izuku sighs contently, letting himself become a deadweight in Katsuki’s hands as they start to deepen the kiss. Experimenting with pressure, pace, Katsuki pays close attention to the omega in his arms before lightly swiping his tongue over Izuku’s petal plush lips. Izuku immediately parting his mouth and allowing Katsuki’s tongue to dip inside, and the feeling of their tongue wrapping together is a bit odd at first, but it’s quickly replaced by a need for more, Katsuki and Izuku pushing onto each other like waves crashing against the sand.
Izuku whines as Katsuki ducks his head to start kissing down the omega’s neck, a feverish need to nip at at skin and run his tongue over the freckles, inhaling the inebriating scent of Izuku’s arousal and need for him, for Katsuki .
He swipes his tongue over the scent gland at the crook of Izuku’s neck, swollen underneath and making the skin tender, causing Izuku to throw his head back, baring more of his neck, and moan .
Katsuki thought Izuku’s normal scent was intoxicating, but Izuku’s heat scent is electrifying . Bolts of lighting hit each and every nerve in their bodies as their pheromones crests together, trapping them in the flames of a forest fire, rich and heady and thick like honey on their tongues.
“God,” he murmurs, “you smell so fucking good .”
“ Please ,” Izuku whimpers, trying to relieve the ache in his pants by rolling his hips over Katsuki.
A low growl rumbles through Katsuki’s throat as he holds onto Izuku’s head and waist before tipping them back onto the dusty floor, accidentally knocking the flashlight away from the boys, the light now hitting against the walls that surround them, cloaking them in shadows, an almost pitch black darkness.
But there’s a throbbing pulse of need thrumming inside their bodies - bright, syrupy, and red .
It’s a messy clash of tongue and teeth and saliva as they rut against each other, the relief washes over Izuku like a drug, the saturated euphoria makes his head feel light but his gut heavy. He aches in his pants, a bit unsure as to what he should be doing, but wanting more than the fumbling that’s happening, wanting Katsuki to meld their bare bodies together with his hands as hot as a brand.
He tries to pull away at their clothes but his hands are weak and his fingers are slipping, “ More ,” he begs, “want more, Kacchan, wanna feel you-”
“I got you,” Katsuki grunts, dropping his sweaty forehead against Izuku’s as he goes to undo the zipper at the front of Izuku’s suit, pulling it down as the omega arches his back to help, bumping their hard cocks together, “I’ll give it to you, baby, I’ll take care of you.”
Izuku keens , the omega absolutely blissful as the molasses pull of his heat drips out of him, clenching around nothing and cock twitching. Katsuki rids him of his clothes and immediately begins running his hands down his body, massaging the flesh and molding Izuku like putty.
Katsuki traces every dip and curve on Izuku’s body, trailing a path of kisses down to his sex, bracketing Katsuki’s shoulder between Izuku’s thighs. He tentatively reaches over, slowly circling his hand around Izuku’s cock where it stands, pink and pretty and the head beading with a pearl of pre-cum. Izuku gasps at the contact, a jolt sending through his body as his cock leaks a little, and his hole dribbles out some slick.
The alpha is absolutely ecstatic at the sight, and Katsuki is completely mesmerized.
“I wanna taste you,” Katsuki breathes out as a sort of warning, before diving between Izuku’s legs and licking up the spilling slick.
Izuku gasps and Katsuki moans at the taste, swirling his tongue around the tight ring and wrapping his arms around Izuku’s legs. Katsuki plays with the flow of Izuku’s pleasure, coaxing his body to let out more slick as he flattens his tongue, mixing the wetness pooling with his own salvia. He carefully pushes his tongue inside Izuku’s ass, and Izuku’s hips grind down on Katsuki’s face, searching for more of his alpha’s touch and tongue.
There’s a million things that Katsuki wants to say, he wants to tell Izuku that he’s being so good for Katsuki, he wants to say that his omega tastes so fucking good . But he can’t, because he’s greedily drinking up Izuku’s arousal, ambrosia in his mouth and it makes Katsuki feel like he’s in heaven. It’s addictive and dangerous and Katsuki is unable to do anything but continuously feast upon the taste of saccharine berries on his tongue, the tarte aftertaste having him salivating for more sweetness.
Izuku threads his fingers through Katsuki’s hair, unknowing what to do with his hands. He tilts his head back and lets out a string of pitchy mewls and debauched moans. He feels so sensitive and everything overwhelms his brain as he feels the heat of a nebula swirl rapidly inside him, stars sparking and spitting stardust to every nook and cranny of his body. Katsuki’s tongue in his hole, hands on his body is better than anything Izuku’s ever felt.
“ Ah! Kacchan- oh god ,” Izuku whines, feeling himself rise to the familiar feeling of his climax, except it’s so much more intense , a hollow ache inside him that longs to be filled, stuffed to the brim, “ Alpha ,” he speaks mindlessly, letting his instincts guide him, “ Please, need you inside me.”
Katsuki pulls off, taking jagged breaths, wiping the glistening off his chin with the back of his hand. He’s trying not to lose himself in the sea of hormones flooding through his body, but he’s quickly drowning in his instincts to claim, to mate, to take , fighting against his alpha that bares his teeth and demands that he rages a path of fire through his omega’s body. But Katsuki grits his teeth and forces himself to calm down, to be slow, to be gentle with the boy that he loves.
“Need to get you ready for me,” Katsuki slurs, “you’re so fucking tight , baby.”
He feels thick fingers start to prod at his drooling hole, before they dip inside his honeyed body. Izuku’s breath hitches in his throat as the fingers slowly pump themselves inside, gently stretching him out. They explore around Izuku’s gummy walls, curiously bending and curling, the pads of Katsuki’s fingers dragging in and out until it bumps against a bundle of nerves that makes Izuku jolt.
“ Ah! ” He cries out, hips jumping down on the fingers.
Katsuki aims for the sweet spot again, curving his fingers carefully, “Here?” he asks, experimentally bumping against Izuku’s prostate.
Izuku wails, hips straining as his body heats up more and more as Katsuki works his fingers inside. Katsuki continues his ministrations as Izuku’s body warms and melts around the digits, drenching them in slick as he scissors and stretches them out, preparing the omega’s body for his cock.
Katsuki nips his way up Izuku’s feverish body, using his other hand to stroke Izuku’s cock painfully slow, and he buries his face into the crook of Izuku’s neck, scenting the omega and breathing in the cloying scent of embers sparking off wood and rosey lust.
“Want you,” Katsuki murmurs, completely losing himself to delirium.
“Need you,” Izuku whimpers back, lifting his hips and bumping against Katsuki’s clothed cock, straining painfully hard in his pants. Izuku's hand reaches down to Katsuki’s belt, sweaty and scarred fingers trying to yank it off, growling in frustration, “Off,” he demands, “off, off, off-”
Katsuki lets out a breathy laugh as he rids himself of his pants, his thick cock jumping out, an angry red and leaking. A needy and feisty omega has his alpha very pleased.
Izuku licks his lips and swallows thickly. “You’re so big,” he mutters, completely out of his mind, head falling back onto the concrete, heart aching in his ribs, “big- big knot , gonna fill me up so good, alpha’s gonna fill me up so good .”
“Fucking hell, Deku,” Katsuki hisses, “you can’t just say that.”
“ Please ,” Izuku begs, watching Katsuki with blown out eyes, submission and softness dancing in the darkness like fireflies dancing under the moonlight. Katsuki wants to trap this feeling in a jar and keep it forever, watching in amazement as Izuku willingly sinks inside this honeytrap, sticky sweet love flooding his veins with every pump of his heart, “Please, please, please-”
“Don’t beg,” Katsuki immediately says, his heart beating erratically and lodging in his throat, “Don’t fucking beg like that, baby, I’ll give you anything you fucking want.”
“Want you inside,” Izuku breathes.
“Okay, okay- fuck , yeah, okay.”
This is happening now , Katsuki realizes, like right now , right now.
He drags the tip around the soft and winking rim until it catches against Izuku’s sopping hole, and they both hold their breaths as Katsuki carefully pushes inside. Izuku’s hole stretches happily around the girth, every inch that works inside is clenched snugly against the silky walls.
Katsuki is taking his first time, Izuku distantly realizes, body filling with warmth, clenching around the heavy cock as Katsuki sinks inside.
Izuku makes a strangled sound that has Katsuki halting, looking down and seeing the way the spongy rim is struggling to spread around his girth. He worries for a second, thinking that he’s hurt Izuku, but the omega simply rolls his hips, searching for more cock while he makes the same choked noise, and Katsuki realizes it’s a sound of pleasure .
Fuck .
Katsuki balls his fist and grits his teeth, dropping his head down onto Izuku’s chest, “S’warm,” he murmurs, “I can- I can feel you around me, fuck , you’re so- soft .”
“Kacchan’s inside me,” Izuku mutters, lips pulling into a delirious grin as his eyes flutter shut, “Alpha’s inside me, my alpha, my alpha is filling me up so much-”
He cuts off with a moan as Katsuki bottoms out with a fluid thrust, pressing his thighs against the curve of Izuku’s ass. It’s round and fits in Katsuki’s palms beautifully , he can feel the dips of the stretch marks that extend out to Izuku’s thighs, tracing them delicately.
Izuku feels so full . He can feel their sexes pulsing together, impossibly deep as the lines between their bodies blur, liquifying them into a puddle of carnal need and blinding heat, the air muggy and thick with the omega wailing, wanting the heavy weight of Katsuki to pin him down and take , blending with the alpha’s unfiltered desire of claiming , leaving his mark on the body that irrefutably belongs to him.
Scintillating sparks glow in their eyes as the alpha and omega inside Katsuki and Izuku howl , the cries echoing through their bones and vibrating on their skin.
“ Kacchan ,” Izuku garbles.
Katsuki pulls them into a kiss, breathing into each other, still clumsy and trying to figure out a dance that leaves them both dizzy and disoriented.
“Kacchan’s mine,” Izuku slurs, wrapping his arms around the alpha’s neck, “Kacchan’s mine .”
“All yours,” Katsuki says, gripping the sides of Izuku’s waist “‘M all yours, baby, s’all for you, for my pretty omega.”
“ Alpha ,” Izuku pants, tilting his head to the side and baring his neck, “M-Make me yours .”
Katsuki drops his head down, mouthing around the length of Izuku’s neck, gently nipping at the sink before he breaks the skin. His mouth fills with Izuku’s pulsing blood, metallic on his tongue and screaming for Katsuki. He doesn’t bite the scent gland, even in his lust-addled mind he knows that they’re both too young for that, and while Katsuki does want to mate Izuku, he wants to do it after courting the omega properly . His alpha grumbles, but has some respect for his reasoning.
Then, Katsuki draws himself back, struggling a bit against the tight clench Izuku has around his cock, before snapping his hips and drilling himself back into the wet heat.
Dulcet moans escape from Izuku as he feels heat bloom all over his body, spilling love from his skin as his blood pulses with desperation, feeling sparks zapping every nerve, every pleasure point inside. He gets lost in a hazy euphoria, bliss exploding through him like a bomb. Katsuki’s cock fits so perfectly inside him, the swollen tip hitting his prostate and length dragging against his walls deliciously, giving Izuku exactly what his body craves.
Katsuki’s tongue laps against the bite mark, on Izuku’s searing skin, as he plunges himself again and again inside the drooling hole, the squelch and slaps of their skin of Katsuki fucking Izuku with unadulterated need fills the space, rings off the walls, overwhelming their senses as they feel everything between them, around them, inside of of them.
Izuku’s body quivers, a riptide of hormones and instincts singing through him as he’s laid bare, the mindless gratification of fulfilling his primal urges makes him keen. And Katsuki feels it all crashing through him like a tsunami, easily getting drunk off the thick scent he’s inhaling and the feel of Izuku’s ass around his cock.
Though they want nothing more than to get lost in the feeling for as long as possible, they’re both still inexperienced, both unable to draw out the euphoric sensation before they start to feel themselves become overfilled with pleasure. Izuku can feel the way Katsuki’s cock becomes thicker, the way his thrusts become faster and more frenzied, and the way his own body is coiling so hard and begging to be filled by a knot already.
“God, shit, fuck, fuck ,” Katsuki grunts, sweat dripping off his forehead, the roots of his hair becoming damp, blond spikes drooping, “Gonna- gonna fucking knot you, fuck ,” his grip on Izuku’s waist tightens, “Gonna stuff you so fucking full of my cum and knot you, baby, d’you want that? Wanna be filled up with your alpha’s cum? Wanna get fucking stuck on my fat knot?”
“Yes!” Izuku cries, wrapping his legs around Katsuki’s hips, “Want your cum, alpha, want your knot, please, please, please -”
Katsuki’s hips stutter as his knot begins to swell, pistoning his cock inside as he works towards his release. He slams himself inside all the way as his knot pops fully, locking their bodies together. Thick cum floods into Izuku’s body, and the omega clamps down like a vice as he cums with a cry of his alpha’s name. He spills all over his abs, rope after rope spurting out while Katsuki grinds his hips, savouring the white hot pleasure that lights through their bodies.
Katsuki collapses beside Izuku, drawing his blissed out omega into his arms, licking around his face. Izuku nuzzles inside Katsuki as his chest heaves, trying to even his breath out as the rumbling hunger inside him is subdued.
“My omega,” Katsuki murmurs, “So good for me, my omega, my Izuku, so perfect for me.”
“Kacchan,” Izuku mumbles, “Feels good… feel tired.”
“Sleep, baby,” Katsuki says, peppering kisses onto his forehead, “I’m here, don’t worry.”
“What happens after this?” Izuku asks, feeling himself thinking with a bit more clarity.
“The heroes should be coming to get us soon.” Katsuki pauses, lips on Izuku’s skin. Then he sighs, “I- I can take care of you for the rest of your heat, if you want-”
“I do,” Izuku immediately says.
Katsuki holds him a bit tighter, “After this I’m gonna court you properly, okay?”
It’s a bit funny to Izuku, having Katsuki court him after the omega’s body has already been taken by the alpha. Though, his heart sings at the idea of Katsuki giving him presents, taking him on dates, taking care of him .
But still, Izuku’s shy, “You- you don’t have to.”
“I want to.”
“Oh,” Izuku finds himself grinning like a fool, “Okay. Yeah, okay.”
“Okay,” Katsuki breathes.
They embrace each other in a cocoon of their safety, purring softly and nuzzling gently as Izuku is lulled to sleep. Their bare chests press together, tangling the garden of flowers that have bloomed within their rib cages, as the specks of stardust fizz out and draps a heavy cloud of security over their bodies.
Safe , Izuku’s omega says, safe with our alpha .
And for once, Izuku agrees.
