Chapter Text
Kirishima was correct. As soon as they were in the car, Katsuki dragged Izuku into his lap, carefully putting his lips to the cheek that had been slapped. It wasn’t red anymore, her arm hadn’t been that strong, but Izuku closes his eyes and shivers with it anyways. He slowly let’s go of the tense stress Ochako’s sudden appearance had inspired in him. His omega slowly relaxes from the tight, defensible spiral it had coiled into, ready to fight, ready to win.
“I’m okay Kacchan.” Izuku whispers.
“She’s fucking dead.” He promises darkly, against the innocent freckles that didn’t deserve such language. His nose draws down to Izuku’s scent gland, bare and ready, and he uses the omega pheromones to calm himself.
“No, she’s not. Don’t kill her. Actually, don’t kill anyone, not for me.” Izuku frowns.
Katsuki sighs, but notably doesn’t answer. Izuku doesn’t want to know.
“I think,” he says archly, shuffling on his knees to fit Katsuki’s lap better, spread as he was in the backseat with one of Izuku’s legs on either side of his hips. Izuku moves his hips in such a way that Katsuki stiffens, gritting his teeth, hands tightening so much Izuku hopes, hopes they’ll bruise into full hand marks he can wear around for weeks and—
Oh, he’s so wet it’s soaking through his pearly lace.
“I think that you need to remember that I’m here. You’re not thinking of anyone else are you, daddy?”
He hadn’t undressed when they left, only thrown his long coat overtop. So, when he unbuttons the big black expensively shiny buttons, he opens the coat slowly, sexily, so that Katsuki can enjoy the unveiling.
Red eyes burn, darkening with a pupil that fills nearly entirely black.
The hands tighten so hard he gasps with it, before releasing and dragging fingers up the strings of pearls and lace to touch over his nipples, flattening to drag over his entire body. One hand even dips to run between his thighs, over his hot, waiting cunt and he jerks with it, shocked at the possessive touch. Kacchan’s hands are firm, lustful, forceful.
Izuku’s never felt so wanted in his goddamn life.
“Just you, baby, just you.” Katsuki answers, and Izuku has to kickstart his brain to remember what he had even asked. “I have you now, I’m not letting go.”
“You’ve had me for months, Kacchan, but now I want to feel it.” Izuku whines into the car, thankful for the glass partition that blocks the driver from having to witness this.
“Anything not to do?” Izuku whispers into his alpha’s mouth, teasing a kiss but not giving it to him even though his alpha’s neck strains for it.
“More a warning for what I wanna do.” Katsuki answers, licking his own sharp canine. His eyes are hot, narrow and severe, taking in Izuku’s every shift and wiggle. “Call me daddy, baby. Call me alpha too, I wanna fuck you bare, we’re both clean, gonna call you beautiful slut, gonna make you slick and squirt, can I do that?” Katsuki asks with his hands cupping Izuku’s ass, squeezing tightly, making it bounce. “Can I make you come baby, on my tongue and my cock and come all over you, give you a new pearl necklace?”
“Yes,” Izuku breathes, kissing him quick, fast, too hard to catch and biting his bottom lip, making the alpha growl at the feeling of sharp omega fangs. “Mm, Kacchan, yes, cover me all over. I like, I like your alpha desires, the way your hands feel, your teeth. I…uhmm—” He laughs as Katsuki suckles a harsh spot on his neck, a few centimeters form his gland and threatening to make Izuku’s eye roll with the hint of marking, the hint of a claim. “Just no butt-stuff, okay?” It’s not his thing, not with any previous partners, and not without warning. Who knows what he’ll do with Kacchan though, this man could probably make anything feel good.
Katsuki snickers into his neck like a preteen.
“Okay, baby, no butt stuff.” He bites into that new hickie, and fingertips dig into Izuku’s ass cheeks. “Can I spank you?”
“Yes!” Izuku’s hips move without permission, rubbing himself over the hard line of Katsuki’s cock in his trousers. Katsuki groans at the move, at the tantalizing hint of omega pussy right there, wet and hot for him. “You, you can. You can also, pull my hair like, like this, Kacchan.” Izuku demonstrates by gripping his fist into blonde hair, tight and close to the scalp so its more of an even pull, not a yank on hair but a dominating move of the entire head. Katsuki growls, deep, dangerous and Izuku’s omega shivers at the possible threat.
“I can do that.” Katsuki licks his swollen lips and Izuku stares at him, utterly besotted. “I like that too. I’ve got kinks baby, but this time, this time I’m gonna show you who you belong to. What my omega deserves from me. Gonna mark you.” A small question in that last part, not quite asking but not quite demanding. Red eyes watch him, and Izuku puts his hands to those cheeks, holding his alpha close.
“Yes, Kacchan, mark me. I want to claim you and I want you to claim me. You’re mine now, too.”
Katsuki’s smile is shockingly soft, melting Izuku’s heart, but then the look in his eye grows wicked and he puts his hand into green hair, gripping it tight like Izuku had just demonstrated. His head is pulled entirely to the side, and his neck exposed.
Katsuki licks directly over Izuku’s swelled mating gland, bold as you please, drooling over it so he’s drunk on omega pheromones and Izuku is vibrating into smithereens in his lap. He cries out sharply, an omega keen.
The car stops, engine cutting.
“We’re home.” Katsuki says against that aching gland, and Izuku’s eyes nearly roll with how good that feels. How good that sounds. He shakily slips off the man’s lap, tugging his coat awkwardly around himself again, shy. They’re parked in a parkade, and the cars lined up and down the aisles are all luxury models that make Izuku’s mouth run dry imagining scratching.
“Goodnight, sirs.” The driver says, nodding his hat to Katsuki and Izuku. He’s entirely professional, not letting on that their general state of dishevelment means anything to him at all.
Izuku softly bids him goodnight as well, tugged along as he was on Katsuki’s heels into an elevator. The top button is pushed, along with a beep of a keycard.
Cuddled in tight to Katsuki’s side, Izuku has an alpha nose running back and forth in his hair, huffing in his scent like it was running out.
“Kacchan,” he chuckles, cooing. The elevator ride is long, but with the charged energy shared between them, Izuku is content to wait this much longer.
Katsuki’s penthouse is immaculate. It’s shining with white marble and stately dark wood, ringed with floor length windows. The surrounding city skyline shines below them, Izuku almost feels a sense of vertigo at the height. In their view, there’s no other competing building to mar their lordship over the city.
“Oh wow,” he breathes, and leans back into the alpha as he comes up behind him. They’re reflected in the glass window, and Izuku can just meet Katsuki’s eyes as the alpha leans down to put his nose against his neck again, lips pressing just lightly to his skin, and his warm palm sliding down to open Izuku’s coat.
“It’s fucking good to see you in my den.” Katsuki rumbles against his back.
Izuku’s cunt is cupped by that large hand, firm and yet still gentle.
“Kacchan,” Izuku breathes, sighing with pleasure as fingers move in a spellbinding circle, rubbing him right through the lace. He curls his own hands into Katsuki’s shirt, holding onto him to remain standing.
“Izuku,” Katsuki answers, and only steps back when Izuku shrugs the coat off, turning and losing that hand between his legs but putting his own trustingly into that palm.
“Take me to bed, alpha.” Izuku says softly, heart trilling and omega cooing when Katsuki kisses slowly and reverently over his eyelids.
Katsuki leads him down the hallway, Izuku’s feet kicking off his heels as they go. Suddenly flat-footed, Izuku feels all the smaller with the alpha looming ahead of him, and he blushes shyly under the glint of red eyes.
Katsuki’s above him, and Izuku wants to look around, wants to investigate this new room (new nest, his new nesting place, ready and waiting for him, his touch, his scent), but most of his attention is swallowed up by the way Katsuki kisses him slowly. Slow, sensual, pushing. His large hands take Izuku’s ankles and part his legs, leaving him widespread in the bed, thighs open for Katsuki to put himself between.
And, fully clothed, Katsuki presses his rock-hard erection into Izuku’s laced covered cunt.
Izuku huffs a whimpering noise through his nose. High pitched and wavering, his legs close around Katsuki’s back and pull him in tighter, accepting the nearly unconscious grind the alpha started, hips seeking to move inside Izuku regardless of the layers of cloth parting them.
It’s good. It’s so good. Izuku’s stomach flips in anticipation.
Katsuki removes his pearl lingerie delicately, a deep contrast to what Izuku half expected the rough alpha to go for. Perhaps he understood that Izuku loved this pearly piece and wouldn’t want it harmed, regardless of whether it could be replaced. He’s being kissed down his chest, a nipple getting some good, sweet suckling when the bottoms are pulled away from his cunt with the telltale slick feeling and Katsuki groans, vibrating through Izuku.
“You’re so wet, baby, fuck that’s perfect. My good slut.” Katsuki says into Izuku’s chest.
Threading his fingers through blond hair, Izuku sighs, smiling. He bites his lips in excitement when a finger slips through his pussy lips, drenching itself in wetness, and Katsuki’s mouth trails its way down his abdomen. Then that mouth reaches its destination, growling in pleasure at the taste.
“Oh, oh, Kacchan, less pressure to start, sensitive, I’m—” Izuku asks breathlessly, legs curling up around Katsuki’s head at the first, too-hard sucks.
Gentling immediately, Katsuki licks slow and careful around the nub of his clit, not touching it. Perfect, that’s—
“Perfect Kacchan, perfect,” Izuku whines, eyes closed although he desperately wants to watch, one hand abandoning the blonde hair to press against his own mouth in reaction.
Katsuki slurps, pulling away to swallow it and lick, and oh, wow, Izuku’s trembling for him to touch him again, to eat him like that again, please,
“Oh, please!” Izuku shivers with the surge of pleasure that comes from Katsuki kissing his cunt like it was his lips, licking in, around, then broadly, lightly, over his clit. That’s so good. That’s good, that’s good, that’s good!
“Like that, Kacchan, just like that, you can,” Izuku’s thighs quiver about Katsuki’s ears and he looks down to find red eyes glinting up at him darkly, mouth sealed to him, voraciously hungry, “faster, you can go faster, not harder yet, not…”
The coaching does the trick, Katsuki goes faster with that broad, careful lick that moves Izuku’s whole cunt in his mouth, his lips and his clit, without overwhelming him.
“Kacchan, Kacchan, oh please!” Izuku cries out, yanking on his hair, “harder, harder like that, faster I can, I can come on that, just that, that’s so good that’s!” He’s pinned down, as he realizes his hips have begun to move against Katsuki’s face, to hump him and his tongue that was doing wonders, how is he not tired, how is this so good? Izuku can’t think anymore, his eyes are unfocusing, his entire being is starting to light up with lightning, jittering through his limbs, heat pooling in his cunt and oh, oh, Katsuki has two fingers inside of him already, slipped right in with the slick and the stretch to curl perfectly into his g-spot, crooking in a come-hither motion that’s moving faster and faster and---
Izuku loses sight of time and space in the midst of his orgasm, stuttering with shock at its sudden, impossible strength. His thighs clench around a head that refuses to release him, he cries out, he’s breathing so fast so sharp that his mouth feels dry, he’s, oh he’s coming, he’s coming---
White pleasure.
Xxxx
Katsuki pants, resting the weight of his head against Izuku’s inner thigh and devouring the sight of that pussy clenching around nothing, framing it with his thick, slick-smeared fingers. He’d stopped when Izuku had weakly whimpered, pushing sloppily at his forehead for mercy and not too soon, either. His jaw aches, but it was so worth it. Giving himself (and Deku) a moment to rest, Katsuki kisses around the thigh his head rests on, then up over the hip and belly, the chest with those sweet, flat omega tits, and then up Izuku’s neck where his mouth still gaped open, gasping in air.
“Kah-Kaccha-nn-mmmm,” Izuku moans into his mouth, shivering with the light aftershocks of his climax.
“Yeah?” Katsuki whispers.
“Yeaaaah, how did you…” his mouth turns upwards, smiling, genuinely amaze and Katsuki’s alpha huffs, smug.
“Listened to my fucking omega, didn’t I?” Katsuki grins, licking that pouty bottom lip clean of spit. Then he dives in again, letting Izuku moan into his mouth and suckle his tongue. It’s good. He’s so hard, but its so good just to feel Izuku beneath him. To know he’s made him come so hard on his tongue and fingers alone.
“Good job, alpha,” Izuku praises prettily, eyes lidded and satisfied but still so very, very hot.
Katsuki presses another kiss to Izuku’s mouth, and they share the taste of him until it’s all licked away.
Izuku’s hands travel around Katsuki, tugging at his shirt, then his belt.
“Want me naked, omega?” Katsuki says against his mouth, smirking. “Ask pretty for it, slut.”
“Kacchan,” Izuku whines, pouting, blinking his beautiful eyes. He’s still wearing his usual pearl earrings, and the difference between the elegance of the pearl and the naughtiness of his mouth is delicious to Katsuki. “Kacchan, please, I want you completely naked, just for me. My alpha, so strong,” he coos, even as he unbuttons Katsuki’s shirt.
Chuckling at the teasing tone Izuku adopts, Katsuki stands to take off his shirt. As he’s in the middle of it, though, arms trapped in their sleeves, Izuku’s sitting up and yanking on his belt, practically snapping it as he rips it open, then pulls it viciously from his trouser belt loops.
Stumbling around, privately a little shocked at the strength in Izuku and his pushiness, Katsuki bares his teeth down at the omega and strips himself of the rest in record time.
Then he’s taking his place back on top of Izuku and they both breathe deep at the brush of his cock over a swollen, spit-wet pussy.
“Want me?”
“Yea, yeah Kacchan,” Izuku replies equally as quiet, lifting his legs to lock around Katsuki, and it’s so easy to hold himself steady at the base and slowly enter Izuku’s hot depths for the very first time.
“Fuck, that’s so good.” Katsuki says, eyes lidded, lips brushing lightly over Izuku’s. They share air, as Izuku gets used to the pressure of Katsuki inside, as Katsuki does a careful draw back and then inside push, going further each time to coat his cock with Izuku’s juices.
It’s a slow roll, a slow churn inside, like Katsuki’s pushing his imprint, his shape into Izuku’s cunt so it’ll remember him forever. His omega’s body will wish his cock never left, will ache for him to return.
One day he’ll even knot this pussy, made specifically to take it, to take Katsuki.
“Fuck, so good,” Katsuki hisses, removing one hand he’d been using for balance and wrapping it around the back of Izuku’s neck. (It lets him stare directly into Izuku’s eyes, glossy and green and fuck, still littered in diamonds). “My beautiful baby, that’s it, you’re taking me so fucking good, made for it. Made for dick.” Izuku can’t seem to handle this kind of talk with the direct eye contact, head rolling around in the bedding like it’s too perfect, it’s too good. Katsuki fills with a strange sense of protectiveness, body inside his omega, filling him up with words and cock. A stripper who’s heard the worst of the worst, still blushing with his cock inside.
“This dick,” Izuku answers, a smile flickering before a good thrust makes him moan. He’s fucked slow, like he’s something special, and he loves it, Katsuki loves it.
Until Izuku’s body screams out for more.
“Flip me over, alpha.” Izuku purrs into Katsuki’s ear, “or let me ride you. I wanna show you how well I can take this cock, fills me so good, Kacchan, oh god, daddy—” Izuku moans, head turning aside to bite the nearest pillow because Katsuki’s sped up involuntarily, listening, hearing that voice want him, want more. It’s not even contrived, it’s just babbling, it’s Izuku putting his mumbling skills to good fucking use and letting Katsuki hear it all.
When Katsuki pulls out, he slaps Izuku’s thigh and growls “Roll.”
Izuku’s roll is smooth, legs turning like he would on the pole, and then he’s bent perfect, showing off his cheeks, his ass, his puffy wet and red cunt hole. Fuck.
Katsuki spits down on it, loving how Izuku twitches and muffles his groan in the bedding covers. It’s a good sight, the long strong line of Izuku’s back, the freckles all over, the way his hands grip into the sheets and pillow.
Katsuki slaps his cock up at the pussy before pushing his way back inside like he owns it.
“Fuck, Deku,” he can’t help but whisper.
Izuku looks at him over his shoulder, eye lidded and Katsuki’s reminded of the way he’d left the stage after that first dance of his, eyes just for Katsuki alone. Shy, demure, but sinful.
“Like it, daddy?” Izuku hums, starting to move all by himself. Katsuki lets go for a moment, hips forward, cock inside, and watches his little love move on his dick. Izuku’s taken it as a challenge, because he works Katsuki’s alpha dick perfectly, one hand reaching through his own legs to cup Katsuki’s balls at the same time.
Izuku clenches his core, his pelvic floor, and Katsuki bites off a curse so feral it shivered through Izuku to hangs around his neck like a chain. He glances again over his shoulder, reaching back with his other hand so he’s mostly rested against the side of his face on the bed, spine bent, and Katsuki grabs hold of his arm, his wrist.
“That’s my alpha, inside of me, all the way to the end of me.” Izuku purrs, practically spellbinding himself and Katsuki at the same time with the slow, wet draw of him back and forth. He’s petting at Katsuki’s balls and his own clit, spreading his wetness, moaning.
Then Katsuki’s helpless to stop himself, his hips start to move, and he’s fucking.
“Fuuuck…” Katsuki licks his lips. His teeth grit tightly, pleasure crawls up his spine to set his hair on end.
Katsuki’s being driven out of his mind. He’s got stamina. He’s not gonna fucking wimp out and come before Deku’s squirted around his cock at least twice, but holy fucking god the omega was eating him up.
“Pussy’s so fucking good, Deku, so fucking good,” He groans, grabbing a better hold around those hips and pulling him back into each thrust. It sends a loud clap through the room as their body’s impact one another, and Izuku quivers, balanced as he was on one arm, the other down at his clit and frantically rubbing.
“For you, Kacchan, for alpha,” Izuku whimpers, gasping and with his dancer’s strength rolling his hips in such a wave that he’s bouncing on Katsuki’s dick. His pussy’s just for alpha, just for daddy. Fuck, fuck, fuckfuckfuckfuck---
Izuku starts jerking, body flinching and grinding and trembling like a leaf. He gasps into the bedspread, groaning loud and proud and oh, so good, as his body clenches and Katsuki bites his own tongue as Izuku comes on his dick.
Fuck!
Orgasm threatening, Katsuki pulls out entirely. Izuku grunts something surprised and bereft, glancing around and finding Katsuki stepping away, one hand tight on the base of his dick, chest heaving.
“Suck.” Katsuki orders, standing at the edge of the bed, and glaring with red eyes. Izuku goes one step further, slinking down immediately to kneel on the floor right at the alpha’s feet. He’s shivery with orgasm, heated and aching and wanting more somehow, more and more and more.
Sensing Katsuki was close too, Izuku chooses violence.
That’s the way Katsuki sees it anyways, because Izuku doesn’t immediately obey, doesn’t suck.
He kisses, wet, suckling, gentle kisses up and down Katsuki’s cock. He runs the very tip of his tongue along the side of Katsuki’s cock, flicking lightly over the head. Katsuki locks his fucking knees.
“Mmm, daddy, you’re trembling.” Izuku purrs like a demon into the sensitive skin between ball and shaft.
“Fuck.” Katsuki lets his head fall back; hand still nobly clamped to the base of his cock. He’s not going to fuck this up. He’s not gonna fuck this up for them and come prematurely.
Izuku mumbles something in return, but it’s garbled by the way he suddenly slurps the entire cock into his mouth, diving down to bob and then right back up to kiss and suckle the head again.
Nope.
It’s too much.
Thrown to his back, Izuku laughs loudly in joyful pleasure as the alpha’s large cock returns to fucking his insides, retreating to spread his pussy lips with the head just to slap against his clit with a wet noise. It feels so good, and it feels better when Katsuki dives back inside, fucking slowly, just in and out, in all the way to the fucking root and pulling out, watching each movement avidly.
He looks up to Izuku’s face, eyes drifted shut, enjoying the sensations, and Katsuki wants that face twisting with orgasm again.
Suddenly, Izuku makes a cute little ‘merp’ noise as he’s yanked clear off the bed. With alpha cock still inside, he’s still a little groggy, but he doesn’t seem to realize what’s happening until he’s got cold glass against his skin. Katsuki’s got him in a tight hold, grin mean.
Izuku squeals sharply a s Katsuki puts his back to the clear glass of his penthouse bedroom, miles above the city. His wide green eyes shoot to red, and his entire body clenches tight around Katsuki, limbs, cunt and all.
“Oh my god, Kacchan, Kacchan, this feels so, so scary, like—” Izuku quivers as Katsuki draws his cock out and then pushes back in, the standing position hitting all different places yet again. “—oh, oohh, like you’re gonna fuck me straight through the glass, I—”
“It’s strong,” Katsuki grunts, licking up Izuku’s neck to find his jaw, hips already working to find a good rhythm, to give Izuku that fuck he’s squealing about, “Daddy’s got you.”
“Oh, fuck,” Izuku whines with it, “Daddy, fuck, fuck, daddy—”
And Katsuki’s blood is on fire.
He fucks Izuku against the window, scrambling for leverage he can’t get because Katsuki won’t allow it, until his green eyes roll back and he’s shrieking into coming again. Katsuki’s hand is awkwardly stuffed down between their slamming bodies to flick over his clit meanly until he comes so spectacularly it splashes down Katsuki’s balls and thighs.
“Daddy!” Izuku’s wailing, unable to move against the onslaught.
Fuck, yeah.
“You squirted, baby, so good for me, beautiful fucking slut, fuck, yeah, fuck, beautiful,” Katsuki groans, peeling away from the window and stumbling back to bed. He places his omega down and stares at him, cock red hot and upright, still hard. On the fucking edge of orgasm himself. He’s panting, gasping in air from the effort but so full of adrenaline and need he doesn’t fucking care. This is so good. Every position, every move they’ve made, so good. Izuku quivers in his bedding, pulling the blankets around himself in an instinctual need for nest, blinking dazedly up at Katsuki with his legs spread and cunt dripping with liquids.
“Alpha,” Izuku croons, eyelashes wet with tears and diamonds, “Alpha, please!” Throat full with omega and submission and need, Izuku’s calling and Katsuki’s lost.
He’s back inside, Izuku’s legs thrown over his elbows so he’s all crunched up beneath him, his cock reaching deep. Katsuki has one foot on the floor, and if it wasn’t nailed to it, the bed would be moving across the hardwood.
He won’t knot. Izuku’s not in heat, Katsuki’s not in rut, this was merely sex for enjoyment rather than for procreation and it was good.
He’s got Izuku under him, his omega, his beautiful flexible omega with his green hair and soft mouth and good heart, and he’s all bent into the perfect press where Katsuki’s cock can drive right down, right in, trying not to push too far to slam into his cervix he won’t hurt him in the bad way and fuck, fuck, fuck yeah, fuck--!
Katsuki’s going to come. Izuku’s whining, eyes lidded, so high on pleasure he’s still shivering. He’s got his blonde head shoved in Izuku’s shoulder, pushing his head aside, finding the gland instinctually, his teeth feel like they’re growing in his mouth, salivating at the thought of biting down.
“Gonna come,” Katsuki grunts, growling, gripping too tightly to Izuku’s leg, pressing his weight too heavy omega couldn’t get a full breath but alpha’s cock was filling, stretching, balls tightening up ---
“Come in me, in me, Kacchan,” Izuku whimpers through his gasps and Katsuki’s leaping into an orgasm that sends sparks up behind his eyeballs, whites out his vision, and shivers through every part of his body. He loses control, slamming inside wetly. In the same instant, he bites on the gland under his teeth, the pulsing of their bodies unstoppable, the claim immediate.
Izuku cries out sharply, omega body coming instantly at the double claim of cock and teeth, shivering underneath Katsuki’s weight and nails biting into his back.
Katsuki’s coming a lot, he thinks, cock pulsing with it, teeth buried, and mouth filled with the amazing mix of Izuku’s concentrated scent and the metallic taste of blood. He’s got a lot of come for his omega; alpha preens.
Katsuki has a thought beneath the alpha’s desires, and with a final suck and release to Izuku’s new claiming mark, he rips away from Izuku’s hold, pulling out. The rip of pain in his back and the heartbroken snarl Izuku gives heightens his pleasure and Katsuki groans through the final throes of his orgasm, holding his wet, red cock and spurting the last of his seed over Izuku’s belly, leaving white creamy drips on his freckled skin just like promised.
New pearls, Katsuki’s come marks. Ready to be rubbed into his lower belly, to mark his womb with the swirls and designs of a gorgeous ancient omega practice. Katsuki pants, trembling, amazed he’s still upright, wavering on his knees and eyes pinned to Izuku who’s hazy and fuck-drunk.
With the omega reaching for him, he puts his still-hard cock back inside, enjoying the huff of moaned air from his re-entry, loving the hot, tight clamp of his body.
“Kacchan,” Izuku sighs, getting his breath back after heroically accepting such a powerful fucking. “Gimme.” He’s pulling weakly against Katsuki’s arms, his forearms and biceps, trying to bring him in closer, showing his teeth in the silent, instinctual display.
The omega’s bite. His heart leaping, Katsuki lumbers down, cock still cradled tight by that beautiful cunt. He notices the red blood at the tips of Izuku’s sharpened nails, and knows he’s been scratched up beautifully. Excitement fills him. Now he’s going to get his own claim bite to match. He’s getting his life partner, his match, his perfect omega, the one he’s been unconsciously waiting for all this time and found in a goddamn strip club.
Izuku snarls like a savage, licking broadly over the alpha’s neck gland and then sinking his teeth in immediately, no pausing, no hesitation.
Grunting between his teeth, Katsuki’s eyes roll back in his head with the new feeling, the sudden wash of Izuku’s pheromones mixing with his own, leaving themselves behind in his mark so he’ll smell like pine and herb forever.
“Mmmmhhhh, dash-ddy~” Izuku moans around his mouthful. Katsuki groans, cock twitching valiantly within Izuku even though he’s spent for the night. He pets over green hair, lightly thumbing the bite mark he’s left in the omega’s neck and allowing the rush of emotions to briefly, only briefly, overwhelm him.
Izuku, and Katsuki. Deku and Kacchan.
Katsuki leaves the bed briefly to grab a warm cloth, a first aid kit, and glass of cool water. He returns to find Izuku blinking dumbly at his red claws and fingertips, like he doesn’t understand how the nail polish has suddenly changed colour…and melted…
“Oh my god, Kacchan!” Izuku startles, moving to sit straight up, but Katsuki has a palm to his neck and lets loose a sharp growl. Don’t move, it means. Quelled and staring up at him with wide, omega eyes, Izuku is shocked bashfully silent.
“It’s fucking delicious, baby,” Katsuki promised, petting over that throat gently, “I loved it. Marked me up good.” He starts wiping between Izuku’s legs, gentle as can be, then moving regrettably over his soiled belly. By the time he gets to the red swollen wound of Izuku’s claim mark, the omega has already cycled through several emotions. First is guilt, because he’s soft as hell, the next is shock for doing it in the first place and then…smugness, letting one stained claw enter his mouth to lick the blood from it.
“Fucking feral bitch,” Katsuki notes, unable to help his own charmed grin when his omega giggles prettily, like he hadn’t just scarred his alpha for life. He treats Izuku’s claim mark with especial care, eyes devouring the very real, very clear sight of his omega. His. Then, he begrudgingly allows Izuku to treat his own as well as the truly impressive scratches on his back.
It’s easy then, so easy, so natural, to bed down with Izuku in Katsuki’s king bed, surrounded by soft materials that he’d stored for Izuku’s use days and days ahead of time. Laying on his back, Katsuki privately relishes in the press of the omega along his side, legs tangled around his, head pillowed on his shoulder, hand laying on his chest and petting little designs over his muscles.
“Goodnight, Kacchan.” Izuku sighs sleepily, content and sore and smelling like a roaring forest fire, sweetened with sugar. He smells like them, their coupling, their mating.
Delicious.
In the quiet between Izuku falling asleep, safe and warm with his alpha, and Katsuki’s own bedtime catching up to him, the alpha pulls out a small box he’d stashed nearby. In the manhandling and omega-throwing of their sex, he’d worried it would have been lost in the bedding, but he grasps it right where he left it, in the pillowcase.
From it he pulls a decadent ring, pearly and iridescent, ringed with crystal clear diamond and worth probably a ridiculous amount in Izuku’s eyes but not nearly enough in Katsuki’s.
It fits Izuku’s finger perfectly because Katsuki doesn’t half-ass these things. He’s possessive, he’s responsible. He takes care of what’s his. The world sits in the palm of his hand, green haired and fluffy, purring up a storm, eyelashes fluttering in sleep.
Katsuki rumbles himself into dreams that seem identical to the waking world, where he’s wrapped up in the omega he’s waited his entire life to claim. His last thought is how well pearls look against that warm, freckled skin.
