“Your Majesty, Prince Shoto Todoroki wishes to greet you.”
“Tch. Whatever.”
The last thing Katsuki wanted to do was to listen to another alpha flaunt their feathers and boast their wealth at him in hopes of ‘wooing’ him into marrying them. But alas, this was a path he’d been forced to walk. There’s talk and tension of the Shigaraki Kingdom slowly inching their ways onto Katsuki’s lands, and despite his militia being closely comparable to what Yagi’s once was, the lack of an alpha as a political figure makes other kingdoms roll their eyes. It’s bullshit, utter bullshit that Katsuki has to deal with being perceived as wrongfully crowned simply due to being an omega. The Bakugo family always demanded the power go to the strongest, the wittiest, the one who’d make the proper decisions with an incomparable ferocity. His mother had been a righteous Queen, someone he’d been inspired to learn from, and yet she as well received remarks of disgust simply because she was a woman. An alpha woman - but that didn’t seem to matter.
~
The Plague of Rot took many by surprise. Adults across the lands fell ill to the infected particles in the air, making them fall into a sickness that rotted them from the inside out. It held no rhyme nor reason that children and the odd older human remained alive after a ghastly eight months time. The Rot castrated the most sound of kingdoms, effortlessly vanquishing any soul that held a crown upon their heads. His mother had just happened to be cursed by fate, cursed along with the rest of the departed by the Gods as they played their chess pieces of misfortune.
Katsuki had been young when the Rot had spread, but not young enough to not be of conscious mind. He’d watched in despair and confusion as his mother turned ill, as his omega father who’d never left her bedside fell ill with her, as the messenger with a grim expression relayed the parchment paper telling of Yagi Toshinori’s passing. The paper was creased, as if the hands that were to carefully tell the world of the Mighty’s passing couldn’t believe nor bear with it themselves.
With the Rot came a new generation out of necessity. Leaders were thrust into crowns and robes and adorned with jewels too heavy for their youthful bodies. Katsuki despised the many weaker noblemen that came out of those months unscathed, those who forced the upcoming generation to settle into titles they were unready for. In his own act of rebellion, Katsuki hadn’t worn the crown Tsunagu had ushered him into until he’d beaten every member of the militia in the training grounds. Even then, once in power, he’d removed them all and appointed entirely anew.
Tsunagu was not the worst elder to have survived, Katsuki would quietly admit. The man never desired the crown for himself and only wished to nurture Katsuki once he’d been left an orphan. When Katsuki had bawled and swung at him for appointing him his mother’s crown, Tsunagu wept his own quiet tears and took the hits, cradling Katsuki in his arms once he’d tired out. Their relationship was minutely unstable for many months until they’d found an understanding.
Something that provided a great help to that was Katsuki’s appointed knight, Izuku Midoriya.
Izuku was an adopted son of Yagi, a warrior in training under the Mighty King. With his father an unidentified bandit and his mother a victim, Yagi had taken the Midoriyas into his arms and heart. Inko had been a dear friend of Katsuki’s mother, a calm voice that travelled between the two kingdoms - Yagi’s sensitive mind in his old age and Mitsuki’s brashness wouldn’t mesh well in direct proximity. Because of Inko, the two kingdoms lived harmoniously where citizens of either could travel without tension nor question. Due to this, Katsuki had become well acquainted with Izuku in their youth, and had found the emotional boy’s trek to become a knight amusing.
“You are training for knighthood?!”
“Y-yes! I want to be strong enough t-to protect and save who matter-”
“That’s ridiculous. You in a set of armor would be nothing more than a Deku.”
The name had stuck.
When Yagi had fallen ill to the extent of counting his hours, the messenger arrived with an uncrumpled parchment. They did not know the paper they held would reshape the entirety of Katsuki’s future.
One for All and All for One,
I bestow upon the Bakugo heir my dearest son, Izuku Midoriya. With this writing I grant him knighthood and honor. He shall protect and serve the kingdoms with grace and strength, and lay his sword down for none other than his Lord. By the Gods and all that is mighty, Young Midoriya will surpass all evil that haunts the land of his beloved. I plead you take care of him and the righteous heart he grants your soul.
With no fear, I declare I was here.
Yagi Toshinori
Katsuki keeps the parchment locked in a chest beneath his bed. His mother had read aloud the message on her deathbed, his father cradled into her side, and with a weak arm handed the paper towards him. With trembling fingers and a dry throat he’d taken it, folded it into his pocket as he watched his mother take her final breaths.
Masaru followed not long behind, declining any offered food or water for days in favor of staying within his wife’s cold embrace.

Katsuki glances over towards Izuku as the palace worker nods and turns around to collect the next visitor. The green haired alpha softly smiles at him incomprehensibly, an expression only years of closely knowing another would convey. Katsuki huffs and crosses his arms, turning back to the doors of the chamber as they swing open.
Shouto Todoroki glides in with an enviable atmosphere of grace, a man entirely polished down to the pleasant sound of his footsteps. Katsuki scowls despite it - he personally knows this prince, is well acquainted with him and has a great knowledge of his volatile family. A revolting waste of time believing Katsuki would wed him and place himself within that mess.
The prince walks closer to the throne before settling down on one knee, a hand over his heart and his head bowed. “Your Majesty, I wish to be granted a conversation with you.”
Katsuki scoffs at the stiff display, the choreography of it all. “Yeah yeah, half and half, what is it that you want?”
Shouto raises his head, his handsome features on display - the infamous scar covering his eye does nothing to anchor his looks, only amplifies his mystique. Katsuki would admit the alpha is easy on the eyes, but he holds no emotion towards his heart.
“I understand you do not wish to wed,” is how the prince begins. And that is what takes Katsuki by surprise.
The blonde raises a brow. “Then why are you here? I’d imagine even you aren’t dumb enough to not know what today’s meetings are held for.”
Shouto releases a breath and brazenly stands without permission. “If I may,” he speaks, holding onto Katsuki’s eyes. “I come with a proposal, both for wed and for not. More of a… unity of power.”
Katsuki spares a glance towards Izuku, but his green eyes are focused solely on their visitor for the moment. He returns his gaze to the prince, releases his arms to rest on the sides of the throne. “Go on,” he urges, maintaining an air of boredom.
“The Shigaraki Kingdom is threatening your lands - and, should they continue, ours as well.” Shouto clasps his hands behind him to assume an unhostile posture, speaking with honesty. “And though I am not appointed of Kingship yet, I am granted exponential more power as my father grows sicker and sicker. While I understand our Kingdom comes with an unfortunately bitter taste, our militia is strong and sound. I propose we combine our power to diminish the Shigaraki empire for good, and grant our kingdoms an even greater range of harmonious travel and living.”
And by the Gods, was that a bold declaration.
“You think that by wedding, our kingdoms would be strong enough to overpower the black magic beasts that raid our farmlands and tear our people to shreds?” Katsuki leans forwards, his eyelids squinting and brow furrowing. “Do you doubt my people have voices and weapons of their own to fight for their own sakes?”
Shouto stays standing tall and proper, seemingly undisturbed by Katsuki’s egging. “There is no doubt that your people are strong - I myself would praise their achievements thus far. But this is not a proposal in regards to the past nor present, but of the future. Tomura will surely grow restless in the upcoming time, and our kingdoms are first in line. What I wish for is the protection of our dear lands and people. Together, we could put up a momentous battle, one that would bring solace for decades.”
Katsuki stares the dual-haired alpha down for many moments in silence, rolling his speech over within his mind. He sighs, straightening his spine and crossing one leg over the other. “Very well. I hear your proposal, and I granted you permission to have said what you said. You speak from a sound sort of reasoning - I’ll give you that much - but your passion lies inhibited by your flesh. I ask that you give me time to process the extent of which you seek from me. Should your patience run thin, I ask that you refrain from reentering this hall if you wish to keep your head. As such, I relinquish you from our time of speaking, and hope you find your way outside with ease.”
Shouto departs with a respectful, unemotional nod. Katsuki releases his own posture to slump down in the throne, thoughts array.
~
Despite how well he may think he’s hidden it, Izuku is in a poor mood once the meetings end. Katsuki can tell by the way he sets his jaw in a near clench, the way his shoulders hunch with a small tension just enough to make them bow forwards, the way his booted foot falls the slightest bit heavier onto the ground beside him.
“What’s your deal, Deku?” Katsuki questions without ceremony.
Izuku grunts before manually fixing his smallest of tells, realizing he could be read by the omega. “Nothing of concern, my Lord.”
Katsuki scoffs, tilting his head towards the alpha. His crown feels noticeably heavier. “Cut the shit, you know that doesn’t work with me. What’s upset you?”
Pursing his lips, Izuku fights to remain silent as they continue their trek down the halls. The King’s gaze is fierce upon the side of his face, however, and he crumbles after a diligent battle in silence. “It’s not really my place to say. However…” He trails off, then drops his thought in favor of meeting Katsuki’s eyes with an air of purposeful questioning. “Are you considering Prince Todoroki’s proposal?”
Katsuki quirks a brow towards him, halting his steps. He watches viridian eyes for any sort of tell, but finds nothing but inquisition. “Shouto had the most reasonable of proposals, and wasn’t just trying to get his dick wet with royalty. Besides,” The omega squints his eyes into a glare, craning his neck towards his knight in a postural challenge. “Aren’t you friends with him?”
Izuku clears his throat. “We are well acquainted.”
Katsuki shakes his head in a small emphasis of annoyed confusion. “Then what would be your concern about it?”
Izuku sighs and leans slightly onto his staff, the casual gesture releasing the smallest amount of tension that had begun to slither into Katsuki’s spine. This may be a back-and-forth between Knight and King, but it was also simply just a conversation between them. The Knight’s lips pursed as if he still failed to find the proper wording for his thoughts, muscles shifting within his forearms. “While I get that the combination of our militias would be something grand, is it really necessary?” Izuku’s eyes almost seem to glow as he gives Katsuki a meaningful look, lowering his voice. “You know I can take on whatever Shigaraki throws our way. No beast has gotten away from me.”
A frown finds its way onto Katsuki’s lips, giving his own meaningful look back towards the alpha. “I don’t doubt that, Deku. But this fight won’t be just beasts.”
“Our men have killed before-”
“But you have not!”
And that was Katsuki’s issue with it all, really. The political tension of being a lone omega in power isn’t something a Bakugo would ever shy away from, nor allow it to make any decisions for them. But despite it being thrust upon both of them, Izuku had become something dear to Katsuki, and the thought of forcing him to reshape the morality of his own already battle-worn hands and mind made the omega feel sickened. Guilty.
Katsuki fists Izuku’s black undershirt tightly, words nearly spat into the other’s face. “You know damn well Shigaraki will eventually arrive to use his black magic by hand. To kill me, you, and all of our people that revolt against him.” There’s a tremble in his fist that the omega chooses to ignore. “Maybe if we had the fucking numbers, we’d be able to overpower him without you needing to throw yourself into the fray - without you being forced to kill or be killed.”
It goes without saying that they both knew the underlying truth - Izuku’s strength and intelligence would be the greatest match against Tomura and his hellish power. And while Katsuki trusts the knight with his entire being, he cannot look past the fact that Izuku always tries to save before he swings. Will inevitably put himself into danger to try and avoid casualty, only ordering their soldiers to go for the throat once he deems every possible avenue of peace is of no substance.
The Shigaraki Kingdom needed to be ended, which means the goal would be the quickest death brought upon their monarch.
One of Izuku’s hands, larger than Katsuki’s own despite the alpha being just the slightest bit shorter, comes up to lightly hold the fist in his shirt. The warm palm does nothing but make Katsuki’s heart feel heavier in his chest, the cool air of the hall flowing softly against the exposed skin of his chest. “Kacchan.” Katsuki clenches his teeth, eyes burning. “I will do what needs to be done. My duty is to protect you. Protect this land, our people.” Izuku’s expression is somehow both soft and hardened, sincere but stern. “If my King does not truly wish to wed, I cannot stand aside and let you do such a thing for my sake. You will always be the most important thing to me - I beg that you trust I will do whatever it takes to keep you safe.”
Katsuki cannot keep his temper down, his heart thudding heavily against his sternum as he keeps his gaze locked onto Izuku’s. The alpha remains standing calmly, hand tightening minutely against Katsuki’s own, his gaze also locked onto the omega’s. It’s silent for many moments as they dissect one another, the only sounds being distant echoes of footsteps in neighboring hallways.
And then, Katsuki smells it - pine, mint, comfort.
It seeps into his bones much too fast for his tastes. A feeling of thick warm water runs down his body and urges his muscles to relax, his mind to ease. His hand starts to fall lax against Izuku’s shirt but remains in the alpha’s loose hold. A thumb sneaks beneath his armill, discreetly rubbing soothing circles into the scent gland on his wrist, and Katsuki feels the fight drain out of him.
He weakly rips his hand out of the knight’s grasp, turning back towards the direction in which they were heading, resolutely not looking back towards the alpha. “Fucking cheating bastard. Don’t fucking scent me.”
Izuku hums, placing the hand that held Katsuki’s into a fist behind his back, straightening up his posture as if nothing was amiss, nothing improper had been enacted. “Apologies, my Lord. My patches must have reached their time limit.” The knight begins taking steps forwards as Katsuki remains still, and Izuku throws him an annoyingly triumphant and teasing smirk as he passes the King. “Allow me to return to my chambers to take care of this. I believe dinner will be ready for you shortly.”
Katsuki grumbles and glares as he watches Izuku make his way down the hall, the green and white of his robes lightly reflecting the rays of the lowering sun through the windows, his staff resting casually over one broad shoulder, grasped in one strong, scarred hand. The omega’s own thumb finds its way beneath his armill, pressing into the gland on his wrist almost mindlessly.
~
Izuku knew what needed to be done, what he had to do.
It was a small price to pay for Katsuki’s happiness. A small price to pay for the omega to remain unwed.
He hated the smell of blood. Its tangy scent a putrid memory of watching his adoptive father heave and hack his life away as the Rot spread. Its consistency of vile clinginess, drying on any surface it can get its grubby hands on and soiling any sort of softness with a disgusting crisp. Its revolting color of red then black, an enraging spoiled mimicry of what could be considered beautiful.
Izuku’s favorite color was red. Red, like Katsuki’s eyes. The color of blood offends him for ever daring to put on a mask of life before it dries into its true revolting core.
And Izuku is covered in it.
The stench makes him want to retch the little food he’d managed to down prior to leaving for the battlefield. He dare not to look down upon his armor, its once pristine silver coated in thick layers of remains and dirt. Scratched by claws and swords and beaks. The number of black beasts he’d slain has fallen uncountable, unimportant.
He had yet to take a human life himself. Yet standing before him is a man with eyes like blood, with long white hair flaunting cleanliness. As if all the bloodshed today had been nothing but a chore for him. Something that could never touch him.
Tomura Shigaraki had sent wave after wave of his black magic beasts to thin their soldiers, savagely mauling those who dodged just too late, those whose stamina diminished just too quickly. It filled the fields with gore as Izuku shouted orders, strategizing how to move towards an ending with the least amount of lives lost. He himself had taken his staff through the bodies of many a beast, the raw strength within him amplified by the blessing of a sorcerer prior to the battle. Ochako had blessed him first with the strongest conglomeration of spells, then slowly withered herself to exhaustion as she donned soldiers with protection. Though many lives had been lost, their numbers still stood strong due to her determination.
Now, Izuku stands with energy brimming beneath his skin, feels it thrum within his staff. He’d always held a higher capacity and compatibility with magic, though he could never conjure it on his own. Yagi had assigned him lessons underneath the warlock Sorahiko in attempts for him to be able to draw out his own power, yet they endlessly proved unsuccessful.
The name Deku tended to echo in his mind, then. He never gave up trying until the elders passed.
“Well now, aren’t you a sight to behold, Midoriya?” Tomura grins, eyeing the lightning-like green magic cascading along Izuku’s limbs like veins. “No wonder my nomus have fallen - you’re looking more a creature yourself.”
Izuku grits his teeth, sneering. “Don’t speak of my name as if we are comrades.”
Tomura’s grin widens, gleeful as he floats above the ground. “Huh ho! Feisty now, aren’t we?” His red (the wrong red, wrong wrong wrong-) eyes darken as he leans forwards, cocky. “You learn to posture like that from blondie?”
Rage clouds his vision as Izuku surges forwards, the ground crumbling beneath his feet as he begins a barrage of attacks. Tomura dances with him with effort, grunting as few blows scrape him, humming as strikes land on Izuku. Each time he manages to jab successfully at the knight, Izuku feels that same sort of nausea the blood causes him. How dare he speak of Katsuki so casually. How dare he further soil the armor bestowed upon him.
They separate and land, each heaving breaths and not once looking away. Tomura’s magic spirals around him unassumingly, though Izuku knows they harden and strike in an instant. Coy, a lie. A mimicry that could be compared to blood.
Tomura hums and tilts his head, eyes flashing. “Where is that pretty little omega who calls himself king?”
Izuku’s breaths pick up, pleading for his scent to remain stuffed beneath his patches.
~
They had fought.
“My Lord, I cannot allow you onto the battlefield. Knowing Tomura’s powers-”
“Who the fuck are you to tell me what I cannot do!?”
“I am your Knight, the one whose sole purpose is to protect you! I cannot fight to my best ability knowing his eyes are preying on you-”
“Oh, so what? You think I’m in need of saving? That I can’t hold my own out there?” Katsuki’s face grows red with anger. An unpleasant red, not like his eyes nor like blood. A frustrating red. A stinging vibrational red. “Says you, the knight with no true form of magic himself!”
Izuku growls, low and threatening. Katsuki just scoffs.
“Did I piss you off, alpha?” He sneers, nasty and crude. “Do I need to go out there and do everything myself?” Katsuki takes bold steps forwards, getting chest to chest with the still growling alpha. He gazes down at Izuku from over his nose, pointedly using their height difference to his advantage. “Can an alpha like you really make the finishing blow, Deku?”
Izuku fights back a snarl, enraged. “Anger me all you want, you are not going out there, Kacchan.” His chest is heaving, every deep inhale in an attempt to calm himself presses his sternum to the fur on Katsuki’s cloak. “I have already said I will do what needs to be done.”
The omega growls. His face is twisted in disbelief, and Katsuki not believing his word pinches his heart more than anything else. “If you go out there and fuck around like you always do, you will die. Dead. You want me to stay here and sit pretty while you go protect my kingdom?”
Izuku steps even closer, their faces now centimeters apart. “Have I not given you enough reason to trust me?!”
“This is not about trust!” Katsuki roars, spit flying from his lips onto Izuku’s cheek. He doesn’t bother to swipe it away, lets it settle into his skin and hopes it helps extinguish the blaze of impulsiveness throbbing within him. “This is about my kingdom being held at knife's edge! There is no possibility of me not being out there for my people! For you!”
Katsuki’s chest is heaving along with Izuku’s, breathless and passionate and devastating. Izuku takes a deep breath. Two. Three. He locks away his rationality as he feels himself slipping.
“...So. There is no hope for me to convince you to stay?” He speaks, quiet. A dangerous sort of quiet.
Katsuki growls once more. “Fuck no.”
And with that, Izuku makes his decision.
Perhaps he knew he’d have to go to such lengths all along. Knowing Katsuki for nearly the entirety of their lives has granted him the intelligence of being able to read the omega, being able to know what decisions he’d make and why. It’s with this intelligence that he’d begun perusing the royal library for information. It’s with this knowledge he’d tracked the calendars.
It’s with this, he’d stopped taking his inhibitors to be ready for this day.
In an instant, Izuku yanks the scent patch off of the right side of his neck. In the same moment he uses his opposite hand to grab the back of Katsuki’s head, shoving his face, and more importantly, his nose into his scent gland. Izuku’s staff falls to the floor with a loud clang, though he pays it no mind.
Unleashing every chained irrationality within him, Izuku allows his rut to take over.
The air surrounding them fills with his scent, pine turning heavier with hints of sandalwood, mint sharpening enough to sting one’s gums. He allows his emotions to pour out, roughly forcing the omega in his grasp to take it all in. Izuku ignores the muffled shouts coming from the blonde, the sharp nails digging into his arms.
He holds Katsuki there for ten seconds. Twenty. Thirty. Forty. By forty-five, the omega has fallen completely lax against him. Panting, flushed, quietly whining.
Katsuki’s heat has taken ahold of him.
Izuku sweeps the trembling omega into his arms, not sparing a glance towards his staff that’s rolled further down the hall. He’d deal with that later. Now, all he focuses on is the omega in his arms, whispering sweet nothings and affirmations into his ear as he carries his king towards his sleeping chamber.
The alpha lays him down on the bed, carefully removing his crown to place it at his bedside. Izuku clinically removes his cloak and pants, placing them gently on the credenza. He ignores his reflection in the mirror just above, ignores to the best of his ability the sweet noises Katsuki releases. Izuku walks back towards the bed and draws the quilt over the omega’s near-naked body, already squirming and sweating in the sheets. He crouches down and uses a hand to brush back Katsuki’s bangs, giving a soft and meaningful pained smile when red, beautiful red eyes flutter open to gaze at him. “I’m sorry, Kacchan. I’ll be back soon, okay?”
Katsuki’s eyelids blink rapidly as Izuku removes his hand, a loud whine escaping him. When Izuku resolutely turns with his back to the omega, heading steadily towards the door, the whines and whimpers turn into cries.
“D-De-ku..! N-no.. Don’... Deku-!”
The door shuts quietly between them. Izuku takes a moment to inhale deeply. Upon his exhale, he moves to seal the door, entrapping Katsuki’s enticing sweet scent and cries within his room. As he stands, he hears their soldiers rallying, and declines himself to spare one last longingful glance at the barrier before he rushes himself into the fray.
~
He’d hoped the scent of blood and gore would be enough to cover it.
“Don’t think I don’t smell him on you, Midoriya.” Tomura’s pupils darken even more as he licks his lips. His alpha fangs elongate as his grin splits his face, cracking the corners of his dry lips. “Don’t tell me you’ve left such a ripe omega to writhe alone in his sheets? And you call yourself his knight!”
Izuku’s breathing gets heavier, messier. He feels the sharp tingling of his own fangs elongated, feels his blood rushing from his brain to his brawn, adrenaline waiting to break free from its ensnarement.
Tomura takes one of his hands (vile, disgusting hands) and grabs his crotch, grunting with a pleased smirk. “Don’t worry. After we finish here, I’ll make sure to take care of him in more ways than one.”
Izuku blacks out.
It might’ve taken seconds. Minutes. Hours. Izuku has little to no recollection of their fight - all he knows is the scent of blood, the sound of screaming, the setting sun allowing relief to his amplified eyes. His rut and the blessings of magic surge his strength to an unholy degree. He became an animalistic version of himself, a measly man who the Gods would either cast away to the depths of Hell or grant him his own temple for worship. When he returns to himself, his hands, face, armor, and staff are coated in blood.
And it feels warm.
The land is mostly quiet around him. The sun has set, night air cooling the liquid matter splattered all over him. A glance tells him the once clean white hair has long turned pink and matted, clumps of it ripped and scattered along the ground. There’s a hole shaped to be just about the diameter and circumference of his staff through the middle of Tomura’s chest, an unbeating heart lying carelessly a foot or two away from the lifeless body. Izuku’s mind is strikingly empty, his heart and breath calming.
Casting his gaze across the lands, he finds their kingdom’s remaining soldiers with their weapons raised high, shouts riddled with exhaustion exuding their victorious pride. Bodies of beasts and fallen soldiers seem to span for miles, yet the ferocity of their people stays strong. The battle had been won.
What needed to be had been done. It’s exactly as Katsuki would have wanted.
…
…Kacchan-
~
Izuku left without a word to the soldiers, entrusting them with their own returns. Cleanup would have to wait should they not attend to it without orders. He had a priority to return to.
Upon his return to the castle, his instincts screamed at him to find the omega immediately, to take care of the mess he’d started. Instead, he clawed back whatever had remained of his sanity, chained and locked it within his mind as he took himself to his own chamber. His armor and staff clangs roughly onto the ground as he discards it within the walls, blood spotting onto the wood beneath it. His ruined scent patches plap onto the floor, leaving a trail as he makes his way to the bathroom. He throws himself into the shower, scrubbing himself as if it was a battle in and of itself. His skin feels raw and sensitive as he steps naked out of the stall, amplified by the rut hormones still festering within him. He barely takes care of drying himself before throwing on his clothing, the uniform of robes he wears as if it was any other day in their kingdom. As if today was any sort of normal.
Only then, when he is cleansed and donned in his mask of normalcy, does Izuku vacate his chamber en route to another.
The seal had worked well for the long hours Izuku had been gone. With a sharp tug he removes the strip holding the door shut, the last of his gifted magic fizzling out with the effort it takes. He’d sealed it tight.
He opens the door and is immediately bombarded with Katsuki’s scent, sweet caramel, salty sweat, distress. Izuku nearly slams the door behind him in an effort to grant his king some imitation of privacy, but forces himself to soften his strength so as to not frighten the blonde. As soon as the door clicks, Katsuki shoots up in bed with wild eyes, shaking and flushed and fearful.
When he sees the alpha who entered his space, he snarls.
“Y-you fucking bastard,” He hisses, venemous and heated and Izuku is so, so happy to hear his voice. He walks towards the bed as if entranced by a siren’s song, unaffected by the barrage of pillows Katsuki pitches at him, continuously spewing curses. “How dare you! How f-fucking dare you pull that shit!” Their eye contact never strays as Izuku finds himself at the edge of the bed, mere inches away from the omega. Katsuki forces a sneer onto his face, his eyes turning tearful. “How dare you leave!”
Izuku falls to his knees, pumping out enough soothing pheromones to sedate an elephant. He smiles weakly, tears beading into his own eyes. “I’ve returned, my Lord.”
Katsuki hiccups, Izuku’s scent calming him despite his rampaging emotions. His body falls lax against the bed, laid upon his side and facing the alpha. They silently shed tears as they gaze at one another, Izuku finding solace in those red orbs, Katsuki’s eyes flickering all across Izuku’s tired, peaceful expression.
The omega swallows, inhaling their mixed emotional scents. “You’re alive.”
Izuku’s smile widens, sheepish and boyish and utterly unbefitting of a man who’d just won a war. “I told you,” He almost whispers, affection and devotion unfiltered in his tone. “I would do what needs to be done.”
Katsuki shutters, his eyes filling with more unshed tears. He raises a shaky hand to Izuku’s face, cupping his cheek with a damp palm and trembling fingers. His scent releases another wave of pheromones, enriched with pride and care and relief, so heavy that Izuku nearly chokes. He feels his own tears fall into Katsuki’s hand, and the blonde does the smallest, most tender of swipes against his cheek. Not quite clearing the emotional waters, more so a reverent touch.
Pink wobbly lips break into a grin, weaker from his heat but still so, so enrapturing. “You’ve done well, Deku.”
This time, Izuku does choke. His heart swells in his chest as the dam in his eyes breaks, tears cascading down his freckled cheeks. He takes Katsuki’s smaller hand in both of his own, bowing his head and placing the omega’s fingertips by his forehead. “K-Kacchan…my Lord, my King…” Izuku’s breath stutters repeatedly, relief flooding his veins, exhaustion and rut intensifying his emotional vulnerability. “I’m sorry, I am so sorry, I wanted to keep you safe, I had to, I had to keep you here, I couldn’t have you out there with-”
Katsuki shushes him weakly, taking his hand from Izuku’s devoted grasp and raking it through his clean green curls. Izuku’s now free hands clutch themselves into fists, as if holding himself together. “I know. I’m really, really fucking mad at you - but I know.” His hand draws down the side of Izuku’s face to his jaw, gently coaxing him to raise his head. Izuku faces his king with flooded emerald eyes, lower lip quivering, cheeks flushed. “Don’t bow your head, my knight. Take pride in the victory you have bestowed our kingdom.”
Izuku bites his lip, the praise and title doing more than just striking his heart. Arousal begins to burn heavily in his lower belly, his cock filling out in his slacks.
Before his scent can give him away, Izuku quickly stands, leaving Katsuki’s hand floating mid-air as the blonde blinks in confusion. “T-thank you, my Lord. I shall return to my chambers a-and grant you privacy at this time.” He bows twice in quick succession, grasping his hands against his trousers to pull them downwards, attempting to keep the fabric from bunching up at his crotch. “My sincerest apologies again for putting you in such a state-”
“Oi,” Katsuki calls, and Izuku stiffens. He keeps his gaze off of the omega beginning to once again pant in his sheets. Katsuki doesn’t seem pleased by this. “There’s no one I trust in this world more than you, stupid Deku.”
Izuku gulps, nodding along to the omega’s words. “I-I’m glad! I’ll always protect you, K-Kacchan!” He responds just a tad bit too loud, lips awkward and posture tight. He quickly turns his back to the omega and takes hurried steps towards the door. “I-I’ll leave you to rest! L-let me know if you nee-”
“Izuku.”
The sound of his given name makes Izuku stop in his tracks, hand reaching towards the door handle. There’s a moment of heavy silence, thick with tension. Izuku hears the sheets rustle as Katsuki sits up, and his ears ring.
“Izuku. Continue your path and leave if you do not want me. But if any part of you does..” He trails off, voice low and quiet and earthshatteringly vulnerable. “...If only for a night, stay.”
Izuku swallows the lump in his throat but does not dare to turn around. “..If you allow me to have you,” He shakily speaks, heart pumping with a fight-or-flight he’d never felt before, “I cannot take just one night. You.. are much too important to me for such a thing.”
He continues to keep his back turned as the sheets rustle once more, listening intently and unblinkingly as the sound of bare feet pad across the polished wood. A lean arm wraps around his waist, a hand softly around his own that reaches for the door, a warm back encompassing his own. The sweet scent of Katsuki overpowers all of his senses besides where they touch.
“Then have me,” the king murmurs to his knight.
Unlike how he’d blacked out before in battle, Izuku finds himself in such a keen awareness he’d be able to look back upon these moments as if watching a film. The alpha turns himself in Katsuki’s hold and yanks him by the back of his bare thighs, causing the omega to yelp and scramble to grab ahold of his shoulders. The sound of Katsuki giggling in surprise has a smile stretching onto Izuku’s face as he takes long strides back towards the bed. He drops Katsuki somewhat roughly into the sheets to make the blonde sputter. Before he can get out any complaints Izuku climbs atop of him, grinning viciously down at the flushed king. “Kacchan,” He exhales reverently.
Katsuki quirks a somewhat nervous smile, never having seen the alpha in such a display before. “Y-ya damn knight, throwing your king around so carelessly.”
Izuku sticks his face into the crook of Katsuki’s neck, breathing deeply before releasing a deep groan at his aroused scent. “Believe me, my lord, I care.” He keeps one hand planted by the blonde’s head to steady himself as the other trails down the omega’s exposed side, relishing in the shiver it causes. “I care deeply.”
Katsuki huffs petulantly, grasping green curls to roughly yank Izuku’s head up. His green eyes are dazed and clouded by lust, overtaken by his devotion and rut. Katsuki smirks as his cheeks flush, biting down on his lip just to watch the alpha’s eyes focus once again. “Then show your king how much you care, alpha.” He purrs.
Without hesitation Izuku slams their lips together, his hand on Katsuki’s waist grasping tight enough to draw a gasp from the omega. He groans as those pretty fingers yank his hair even tighter while he licks into Katsuki’s parted mouth, mapping every surface he can reach, tasting everything he has to offer. He trails his tongue along the underside of the omega’s, teasing and ravishing the appendage until the body beneath him is shaking. He coaxes the blonde’s tongue out and sucks, obscenely wrapping his lips around the cute pink muscle as if it were a cock, and Katsuki squeals.
He moves his hand from the blonde’s waist to his chest, groping roughly at the solid pec beneath his fingers. He exhales in ecstasy into their kiss, lowering his body to be pressed against the other, needing to feel all of him. Izuku grunts as his dick makes contact with Katsuki’s hip, moving his fingers to pinch the pretty pink bud of his nipple as he grinds down, tongue still devouring Katsuki’s mouth. When he finally opens his eyes and gives them the slightest bit of space for their lungs to fill with air, he finds the intoxicating view of Katsuki, flushed and utterly dazed, panting and sweating and squirming under his fingertips lightly flicking against his hardened nipple. “Kacchan,” He pants, maneuvering himself to rest on his elbows so that both of his hands were free to play with the omega’s chest. “You’re sensitive here, yeah? You- you’re so cute.”
Katsuki whines and throws his head to the side, hips bucking up with nowhere to go but against the alpha’s thigh. “Sh-shut up, you freak!” Izuku continues his assault on his nipples as he buries his face into the blonde’s neck, dragging his lips light across the sensitive skin to keep him squirming. When another wave of pheromones are released from the nearby gland, Izuku moans and latches his lips onto the skin underneath Katsuki’s ear, sucking and nipping until he ensures it will leave a bruise. At the lack of sounds Izuku lifts his head, finding the omega biting his lip with a fist to his mouth. Izuku rips a hand away from the other’s chest to grasp his jaw, forcibly moving his head to face him straight on. Katsuki’s eyes widen at the rough treatment and gasps silently, releasing that plump, bitten bottom lip.
Izuku breathes into his mouth. “I wanna hear you, Kacchan. I want to hear all the pretty sounds you can make while I make you feel good. You’re feeling good, yeah?” He pinches the nipple still in his grasp, and when Katsuki whimpers, he can’t help but thrust his cock into the omega’s hip. “Fuck, I want to make you feel so good. Will you let me? Will you let me take care of you, my beautiful omega?”
Katsuki’s breath catches at that, eyes widening in wonder, pupils dilating. He swallows and nods, and Izuku smiles with a small shake of his head. “Uh uh, I want to hear you, yeah? Tell me what you want, Kacchan.”
Katsuki whines softly and averts his eyes, lips trembling like he wants to bite them again but knows better now. Such a good boy. “O-Okay,” He croaks weakly. Izuku feels warmth flood his chest. “I wanna feel good, a-alpha.”
Izuku surges forward to kiss him again, though this time much sweeter. He lets their lips smack wetly against one another, feeling the plushness of their mouths as soft sounds leave their chests, and the obscene noises of their lips fill the heated air between them. Goosebumps filter along Izuku’s spine, making him arch and roll his own body into the heated skin of the omega below him. Once he’s had his fill (for now) of the taste of Katsuki's mouth, he slowly inches himself downwards, mapping his trek with open mouthed kisses along the blonde’s neck, collarbone, chest, ribs, abdomen. When he kisses the lovely hipbone he slides his fingers into Katsuki’s tight boxers, inching them down his thighs. He pulls back to survey the revealed beauty of Katsuki’s sex, wet folds glistening underneath a small patch of soaked blonde curls. His king is a man of aesthetics, after all - of course he’d keep himself trimmed and proper.
Izuku licks his lips and raises his eyes to Katsuki’s face, finding the omega watching him with a shy trembling expression, hands gripping the sheets beside his head. Izuku smiles softly and moves his hand to cradle the blonde’s cheek, reverent, loving. “You are so endlessly beautiful, Kacchan. Everywhere,” He breathes. His eyes follow the lump in Katsuki’s throat as he swallows, noting how the omega presses minutely into his hand.
He trails the hand down Katsuki’s body until he reaches the boxers trapped along his thighs, making quick but coordinated work in fully pulling them off his lean legs. Tossing them aside, Izuku kneels on the bed above his king, himself fully dressed while the blond lays bare, legs twitching with half a mind to cover his modesty. Izuku doesn’t bother to hold back a whimper as he spreads his hands on milky thighs, spreading them open to reveal that beautiful, leaking pussy. He lowers his head to be closer, shifting his legs from underneath him so that he was lying on his stomach. He breathes deeply into the crook of his leg and pelvis, relishing in the musky scent of entirely Katsuki. Izuku releases a desperate noise and flutters his eyes open to gaze upon the beauty that is his king, skin flushed such a beautiful red that Izuku may have to reorder his favorite color scale. Katsuki stares down at him with a clouded gaze, intercepted only by a sliver of humility, and Izuku wishes for it to disappear. He needs his omega to feel safe, whole, utterly cared for in his hands. Releasing one of his hands from Katsuki’s thighs, he slithers it up the sheets, palm upwards, a question, an offer.
Katsuki hesitates for only a moment before shakily bringing one of his own to Izuku’s, squeezing his fingers just enough.
Izuku breathes in and parts his lips, tongue falling out flat as he drags it from Katsuki’s hole to his clit in one slow swipe. The thighs around his head already threaten to tighten as the omega releases the cutest sound, and Izuku tightens his remaining grip. Having gotten a taste, he knew it would never be enough. He loses himself between Katsuki’s legs, licking between each lip, pulsing his tongue against his slit, closing his lips around the bundle of nerves up top, slurping the divine nectar that floods from his hole. His eyes roll back from the taste as it coats his tongue, throat and chin, his hand holding Katsuki’s squeezing back mindlessly at the deathgrip the blonde has on him. He goes from mapping his folds to plunging his tongue inside, deep deep but not deep enough, licking along the walls that pulse around him before thrusting his tongue in and out, in and out. Katsuki’s crying above him, broken sounds of his given name and nickname falling from his mouth as Izuku devours him. The sounds of Katsuki’s stuttered voice and squelching sex are driving him insane, rutting into the sheets beneath him, frustration building at the barriers of clothes he hadn’t cared to remove before servicing his king.
He moves the hand from the blonde’s thigh to his cunt, spreading his lips with his fingers. He licks one last devastating drag from his hole to his clit before he sucks, rubbing the tip of his tongue teasingly along the nub. Katsuki falls apart above him, and he feels it more than hears it. His hole gushes against his chin, pulsing and throbbing as he leaks and leaks into the sheets beneath them. His thighs crush against Izuku’s skull, the soft, sensitive meat of his inner thighs feeling like an angel’s touch against his cheeks. Izuku’s dizzy from the lack of oxygen and arousal as he sucks and licks him through his orgasm, never wanting to part ways with such a divinity. He only removes himself out of pity once the hand holding his turns to nails raking across his palms, Katsuki’s cries turning overstimulated and overwhelmed.
Sitting up he heaves deep breathes, dizzy with how hard his cock is in his slacks. Katsuki lies pliant and twitchy beneath him, floating in his gifted orgasm. Izuku whimpers as he crawls forwards, pushing his mouth against the omega’s, slipping his coated tongue into his mouth so that he may taste the fruitful gift he’d given Izuku. Katsuki’s mouth is nearly lax against his own, lazily kissing back and moaning softly at the taste of himself on Izuku’s tongue, and the alpha can’t get enough.
“Kacchan,” he whines, hands desperately raking along any exposed plane of skin he can reach. “Kacchan, Kacchan, K-Kacchan-”
If his mouth’s not occupied with some aspect of Katsuki’s body, he can’t help but pour out his name in desperation. He can’t believe the gorgeous omega lying beneath him, so open and giving, would ever grant an alpha such as himself this sort of grandeur.
When Katsuki comes back to himself, he raises his hand back to Izuku’s hair, gripping tight. Izuku immediately finds his eyes with the utmost focus, ready to please.
“Izuku, if you don’t fuck me in the next thirty seconds, I’m kicking you out,” He growls, and though it’s weaker in his post-orgasmic haze, Izuku’s heart beats rapidly and his hands twitch to move. He wants to be good. He’ll do whatever it takes to be good for his king.
Katsuki doesn’t allow him to go far, though, as he uses his grip on Izuku’s head to bring him down and press their lips together. It’s the first time Katsuki’s initiated their physical intimacy tonight and Izuku feels like he could cry. He wants this. He wants me. Omega is pleased. Izuku lets Katsuki lead this time, going along with the tender ways their lips press against another, the way Katsuki’s hands find the robes that have fallen from his shoulders. He disconnects them from their kiss and yanks at the fabric, scowling and flushing just the smallest bit more. “Would you undress, for fucks sake? These things are going to be filthy.”
Izuku quickly straightens up and scrambles to obey, flushing at the sound of Katsuki’s breathless laughter at his antics. He has to stand from the bed to fully pull down his slacks and boxers, and when he turns back around he notes that the laughter has subsided. Growing nervous, he picks his gaze up from his discarded clothing on the floor to Katsuki’s face. The omega is fully flushed, mouth parted, pupils dilated as he scans the planes of Izuku’s skin, scarred and tan from many reckless trainings and battle. Katsuki swallows again before raising his eyes to meet Izuku’s. And Izuku, despite the day’s nightmarish qualities, has never felt so happy. So desired, so wanted.
He places his knee onto the bed and crawls forwards slowly, the tension between their gazes molten with heat despite everything they’d already done. This was different. With this, they would become one.
“Kacchan,” Izuku purrs, finally atop of the blonde. Katsuki looks up at him wondrously.
He can’t help the way his hand immediately trails back down the soft body beneath him, inching towards Katsuki’s sensitive, sloppy sex.
A hand on his shoulder stops him in his tracks.
“No,” Katsuki starts, eyes blazing as they never look away from the alpha’s face. “No fingers. Just you.”
Izuku’s breath stutters, fingers pressing into the meat of Katsuki’s abdomen. “K-Kacchan, it’ll hurt-”
“I don’t care,” his king breathes, spreading his legs beneath him. The hand on Izuku’s shoulder glides up to his face, petting his brow before tucking a rogue curl behind his ear. “I need you.”
Izuku’s lips tremble as he fights with himself not to cry. When Katsuki just smiles at him sweetly, he can’t help but let a few tears escape down his cheeks. Izuku sniffs and positions himself properly, taking his hand off of Katsuki’s stomach and instead grasping his cock. He whimpers as he finally feels pleasure, can’t help but take a few strokes of himself to rid of some of the sensitivity. Katsuki watches him as he does so, breathing deeply, eyes entranced by the size, the way it moves within Izuku’s strong hand.
When Izuku finally lines himself up to Katsuki’s hole, head teasing his slit, he desperately moves himself back to his elbows around Katsuki’s head, needing to be close to him. Katsuki hums pleasantly and brings his hands to freckled cheeks, bringing their lips together serenely. Izuku feels his mind simultaneously go clear and blank, tears falling from his closed eyes as he returns the kiss and presses himself in slowly.
After a few inches their kiss breaks as Katsuki gasps, eyes flying open and shooting upwards at the stretch. Izuku stills for the moment and peppers his cheeks and neck with butterfly kisses, shushing him and keeping him within his body. After some long seconds, Katsuki releases a whimper and lightly squeezes Izuku’s cheeks, and the alpha takes that as his cue to keep going. He watches Katsuki’s face as he continues pressing inside of him, taking in the way his mouth falls open helplessly and the way his eyes unfocuses. He looks absolutely stunning as he loses himself being split open on Izuku’s cock. He looks like he’s exactly where Izuku knew he always should be.
When he bottoms out they both groan, Izuku shaking as his balls lightly press against soft skin. Katsuki’s hands move from his face to his back, digging into his shoulders desperately, trying to hold on. The way he clings makes Izuku’s heart soar, makes his alpha whine. He slips a hand between them to rub lightly at Katsuki’s clit, immediately feeling him tense and whimper from overstimulation. It quickens the way his walls relax around him, though, and so he removes his hand in favor of grasping the sheets beside his head.
Izuku pulls out just an inch before pressing himself back in, and Katsuki mewls. His alpha flares at the sound, immediately pulling himself out further before slamming back in, causing the blonde to cry out more pretty sounds, forced out of his lungs by the slamming of their bodies. Izuku can’t help the way he desperately fucks into Katsuki’s soft heat, drunk on the way his walls clench around him, mind spiralling from the whoreish sounds falling from lips just beside his ear. The sounds and smell of sex flood the room so heavily that Izuku can’t breathe without choking pleasantly on Katsuki’s heady scent, can’t think without hearing the wet slaps between their bodies, the gasps and choked sounds Katsuki lets out. Overwhelmed, he stops his thrusts and full-body grinds himself into the warm body beneath him, choking on his own sobs. He’s shaking, aroused beyond belief and so in love that he can’t fucking function-
“I-Izuku,” Katsuki calls, a breath away but not nearly close enough. Izuku trembles as he raises his head to look at him, takes in the way the blonde is drunk on infatuation and pleasure. “Y-you’re doing so well, so good. Making me f-feel so fucking good, alpha. I- uh- I’m so happy, so happy I’m with you. I l-love it, I love you, you stupid, big hearted idiot, you f-fucking moronic b-bastard-”
Izuku’s going to fucking cum.
Katsuki.. loves him? He loves him?
Izuku cries out as he shifts his hips back and plunges back in deep. Katsuki screams. He continuously cries as Izuku sets a pace so desperate, so devastating he fears the omega’s going to truly split in half from his cock, sever from his center in two perfect pieces, a perfect cavern for Izuku to bury himself into. He continues pounding into his cunt as Katsuki chokes on praises, whimpering how he’s so good, such a good boy, such a good alpha and Izuku forgets anything else. Forgets that he’s officially taken a life, forgets that there was ever a war to fight. Forgets everything but the beautiful, loving man beneath him, sobbing and moaning from his dick, so deeply connected to him that he can’t imagine ever leaving.
Can’t imagine ever separating from his Lord. His King. His lover.
Izuku snarls brokenly as he shoves a hand between them, once again finding Katsuki’s clit, but this time goes ballistic with his fingers. Rubs in rough, firm circles that has the omega squirming away from his touch, trying to crawl away from the onslaught of pleasure. Izuku won’t allow it. He keeps the omega pinned underneath his weight, babbling his own confessions of love and lust as he loses himself, fluttering eyes locked desperately onto Katsuki’s own sloppy, beautiful face. He needs to see it. Needs to see Katsuki cum from his cock, needs to see him feel good.
“Izuku- Izuku, Izuku,” Katsuki chants, both out of pleasure and out of overstimulation. Izuku responds with his own purred growl, rubbing his nose along Katsuki’s scent gland. The touch makes Katsuki somehow impossibly tighten, and they cry out in sync. “I-Izuku! B-bite, bite me- bite me, alpha!”
Izuku roars and sinks his fangs into the gland immediately with the permission, and the last thing he registers before he blacks out from his own orgasm is Katsuki screaming loud, hole fluttering and clutching down on him, spewing a sharp spray of fluids onto the alpha’s pelvis.
~
It could be seconds, minutes, hours before Izuku awakens, sticky and sore and so, so satisfied. He groans in his throat as he tries to turn on his side, before realizing he physically can’t - and that’s relayed through a sharp tug from his cock, knotted and stationed inside Katsuki’s quivering pussy.
He immediately sobers and scrambles to find his hands on the bedding, pushing himself up to take in the scene. Katsuki’s asleep beneath him, breathing softly besides his grunt of disapproval from Izuku’s shuffling. His brow is relaxed, face serene and still slightly flushed, hair messy from sweat. It’s the dead of night but Izuku thinks the sun must be rising as he gazes down at the king, his beauty shining like the soft morning sun despite only being illuminated by the moonlight sneaking in through the blinds. Izuku feels a content purr rumbling in his chest as he takes in the bite mark, deep and sure, adorning the right side of his neck. He realizes he can smell it, then - the way their scents are intertwined, barely changing their base at all. If he could view them physically, they’d be wrapped around each other like a strand of DNA, like the tracking of an eagle’s mating ritual, their trusting fall from grace holding on to one another. Izuku’s known his heart was Katsuki’s all along. But to be accepted so wholly, so undeniably reciprocated…
He lowers himself back down as gently as he can onto Katsuki, who sleepily throws an arm around him.
Izuku should begin planning a proper proposal, for once the battlefield cleanup is resolved. He softly takes Katsuki’s free hand, lying beside his head, into his own, rubbing his thumb affectionately across the smooth skin above his tendons, gazing longingly at his fingers.
…Yes, Katsuki needs a ring. A red one, to match his eyes.
