Katsuki is a monster. He knows that, but fuck, he doesn't give a shit. Having been given an out of the hero world, which suffocated him into a world that would actually accept him for all he is, even the darkest, worst parts of himself, was amazing. He didn't regret leaving U.A.—the only thing he regretted was leaving Deku, his Deku, behind. Fuck, what he would do to get his Omega, h̶i̶s̶ ̶c̶u̶m̶d̶u̶m̶p̶, back. Fuck, what he would do to feel that tight cunt lock around his knot again. See those pretty tears once again, hear that cute, mewling moans coming from his Omega once more. It had been over a year and a half since he had left not only U.A. but also left Izuku.
He couldn't risk the Omega getting hurt due to his connection with him. He'd get Izuku back one day, seeing as he kept tabs on the Omega and Inko, and always had someone watching them. Watched Izuku grow as a person and get top of his class. Saw how Izuku had gained more baby weight in his cheeks and had gained beautiful curves. Wide birthing hips, a lean figure, and an even cuter, fuckable body.
Fuck, Katsuki wanted to ruin him.
In due time.
Katsuki groans, rubbing his hard cock through his black sweats, reclining against his headboard. The large Alpha huffs, feeling his cock weep in his loose boxers. Katsuki huffs as he stuffs a hand down his pants, gripping his hard, aching cock. The Alpha huffs as his mind wanders back to that faithful day when it all started. Fucking Izuku on their dinner table, watching those pretty crystal tears streak down Izuku's flushed face. Feeling that pretty pussy flutter around his cock, filling Izuku full with his cum.
The Alpha roughly fisted his cock, shoving his sweats down past his cock, releasing it from his pants. Katsuki huffed as his cock bobs in the cool air, hissing when the A.C. blowing overhead makes his sensitive cock twitch and drool pre. The large Alpha grits his teeth, jacking himself off as his head falls back, squeezing his eyes shut. His mind flickers to the memory of that day playing on repeat, making his cock leak and twitch in his hands.
The Alpha's toes curl as his feet dig into his mattress, gritting his teeth as pleasure surged through him. Tingles scatter and buzz in his body, feeling like little electric bolts coursing through his veins. The tight coil in his gut tightens more and more as the scene plays out in his mind, his heels digging deeper into the mattress. Katsuki growls and snarls, feeling his fangs leak copious amounts of claiming venom, the citrusy taste bitter on his tongue. Katsuki's hips buck into his tight fist, cock leaking pre, the sticky pre-cum running down his cock in thick rivulets. Katsuki groans and hisses, his empty hand popping embers, smoke billowing out of his palm.
//Katsuki hisses, feeling his knot start to inflate, pulling at Izuku's cunt, popping in and out. "Kaa-gguh," Izuku gurgled, saliva running down his bright-red face, spilling onto the table. With an echoing roar, Katsuki shoved his knot into Izuku's tight cunt, feeling the Omega clamp down, cumming together. Katsuki surged forward, clamping down on Izuku's scruff as he let Izuku's throat go, hearing the Omega splutter and choke on the incoming air.//
"FUCK!" Katsuki shouts, hips rising off the mattress, cock shooting ropes of cum onto his black tank, splattering onto the dark fabric. Katsuki grunts and growls, fist locking around his growing knot, feeling it inflate inside his fist, pushing against his tightly clamped fist. After a minute of non-stop cumming, Katsuki's hips flopped down, chest heaving as his cock drooled and spluttered the last ropes of cum, leaking down his slowly softening cock.
Fuck.
He needs to get his Omega back for the sake of his sanity and for the sake of his cock.

Izuku snuffles and mrrps, tossing and turning on his bed. He didn't even know what time it was, but he knew it was already quite late. The Omega hummed and turned into the large pillow, grasping it tightly as he stuffed his face into the shirt covering the pillow. It smelt just like Katsuki, his Alpha, that luscious, smokey scent, with hints of burnt caramel and chili pepper making his nose tingle. Izuku huffs as he breaths in the rich, smokey smell, brows furrowing at how intense the scent is.
It smelt so fresh.
Izuku opened his eyes, breath catching when he met eyes with Katsuki's dark, carmine eyes seemingly glowing in the dark. The Alpha was reclined on his bed, staring at him with a grin Izuku couldn't tell if he liked or not. "K-Ka-..?" Izuku whimpered but was quickly quieted when Katsuki's hand, rough and warm, cupped over his mouth. "Shh, Deku," Izuku's mind felt hazy and loopy, breathing in his Alpha's concentrated scent after nearly a year and a half of going off slowly fading scents on dirty laundry.
"Shh, go back to sleep," Katsuki purred, watching Izuku's eyes flutter shut—the scent-based sedative smeared on his palm, working as Izuku slowly fell asleep once more, breath evening out. Katsuki huffs, taking a moment to hold Izuku close, chuffing quietly, finally able to smell that heady, sweet scent once more. It felt like he's finally alive, that scent flooding his nose and making his entire body feel like it was alive. Rising from the dead of scent withdrawal.
Katsuki carefully bundled Izuku up in his arms, taking a duffle bag full of Izuku's clothes and fleeing into the night.

Izuku awoke slowly, a weak, cracked moan breaking through his chapped lips, feeling pleasure rip through his heavy, sleepy body. Izuku could feel his cunt flutter, the wet, hot, slick painting his freckled thighs. Izuku's eyes slowly cracked open, head twisting backward, looking over his shoulder. The Omega's eyes, hazy from sleep and pleasure, stared into deep, carmine eyes, coming face-to-face with Katsuki. The same Katsuki from a year and a half ago, the same Katsuki who held him the night before he disappeared for good, fucking into him, holding him so dearly. His best friend. His Alpha.
His Kacchan...
"N-..hn, K'cch'n...?" Izuku could feel tears well in his eyes, both from being overwhelmed by the pleasure coursing through his veins and finally seeing Kacchan again after a year and a half away from each other. "Fuck," Katsuki hisses, nipping at Izuku's nose gently, making the Omega squeak, hips bucking in Katsuki's grip. Katsuki huffed as Izuku's cunt fluttered around his cock, that tight heat sucking him deeper.
Fuck, he's higher than fucking ever.
"Fucck, such a good Omega," Katsuki groaned, pressing Izuku deeper into the mattress, fucking into him roughly, growling and snarling. His cock battered and kissed Izuku's cervix, feeling the Omega twitch and clamp around his cock. "K-Kaa?!" Izuku moaned, eyes widening as he choked on a squeal, gripping the bedding. Izuku could hardly breathe as Katsuki fucked into him, those heavy balls slapping against his engored, cherry red clit. Katsuki molded his cunt to his cock, ruining his slick, wet cunt for anyone else.
Not like he needed anyone else, he had Kacchan.
Izuku curled in on himself, the pleasure almost painful, hips trying to run and chase the pleasure simultaneously, tears boiling down his cheeks. "Ka-Kaachan...! T-Too much," Izuku sobbed as Katsuki growled against his neck, lapping up the sweet-tasting, rich oils bleeding from his scent gland. The Alpha's barbed tongue, rough on his skin, lapped over his swelling scent gland. The sensitive scent gland twitched and bled more aromatic oils, making the Alpha groan into his neck. The scent was pure sin—the oils were like ambrosia on his tongue.
Katsuki groans as he mouths Izuku's scent gland, letting his large, ragged Alpha fangs graze and run over the swollen scent gland, teasing it before sealing his mouth over his Omega's scent gland. He suctions to the gland, tongue leaving over it as he sucks the rich oils out of the gland, huffing, and groaning. He can feel Izuku's pulse under his lips, jumping under his skin as he suckles and nibbles. Izuku moans and whines, bucking back into his thrusting cock, that tight heat enveloping him.
"Fuuck," Katsuki groans as he pulls away, licking the sweet oils off his lips with his tongue. "Smell so good, baby...Fuck, you taste good too," Katsuki groans, pulling Izuku back on his thrusting cock, the dull clapping of that sweet, chubby freckled butt smacking against his hips. "Kaaa..." Izuku sobbed, the coil in his gut tightening, his core feeling as if it was dipped in lava. Izuku's eyes were dripping tears, sleepy jade eyes full of heady, dark lust coiling in those pretty jade eyes. Katsuki huffed and groaned, letting go of Izuku's hip as he pulled out. "W-Wha?!" Izuku sobs, trying to chase Katsuki's cock as the Alpha's tip pops out. With a gentle pat to the Omega's hips, Katsuki shushes the Omega, turning him till their face to face.
"Wanna see your pretty face when I fuck you full of my cum," Katsuki growls, gripping Izuku's hip, his own hips shifting as the tip of his cock kisses Izuku's winking hole, slick drooling around the mushroom head. Katsuki grins as he seals Izuku's lips with his own, pulling back as he slams him, holding Izuku still as the Omega jackknifes, twitching and writhing in his hold as he squeaks and squeals. Katsuki swallows Izuku's moans as he starts a rough, unforgiving thrusting pace, nipping and delving his tongue into Izuku's mouth. Izuku whimpers into his mouth, their tongues twisting as he fucks Izuku hard, huffing and groaning. Izuku's cunt squeezes hard around his cock, the slick slide making the pleasure in his core burn bright like a star, heating his entire body up.
Smoke coils and hisses from his bright orange palms, a steadying growing heat against the Omega's hips making Izuku twitch and writhe, mouth popped open in a perfect little 'o' shape. Embers spark and smother against Izuku's hips, the Alpha's hand pulling away before coming down with an explosive spank on Izuku's pudgy, freckled ass cheek.
The explosion was loud but small, the smoldering embers dying in the air as Izuku choked on a scream, eyes rolling back. The Omega clamped down and convulsed, cumming hard. Katsuki growled at that wet heat suctioned him in, finding it harder and harder to thrust in, his knot slapping against Izuku's flushed, dark red folds. "Fuck, gonna fuckin'..." Katsuki groaned, "Knot this goddamn pussy," Katsuki growled, pulling Izuku down harder and harder onto his growing knot. "Want me to fuck you full? Fill you up? Knot your cute little cunt?" Katsuki growled, beads of sweat dripping down his muscular back, watching Izuku's face scrunch up in pleasure, no tangible thoughts behind the Omega's pretty dark jade eyes.
"Y-Yesss...!" Izuku sobbed, blunt nails scratching his arms, drawing deep, bright red welts into his arms as he sobbed, scent spiking with lust and need. Katsuki snarled, saliva and venom drooling down his mouth, a snarl bellowing through his clenched teeth as he shoved his knot in, roaring at the heat in his core reached boiling point, boiling over as his knot popped.
Katsuki's cock twitched as his balls tightened, the first heavy rope of cum spurting into Izuku's tight heat, virile cum painting the Omega's walls white. Katsuki's hips thrusted and bucked with each spurt of cum, leaving his cock, grunting and groaning. "Nnnhgh..." Izuku whined, eyes hazy as he stared at Katsuki. The Alpha huffed as he pulled Izuku close, peppering kisses over Izuku's pretty chubby cheeks, eyes tracing those constellations dotting around Izuku's chubby cheeks. Izuku's purrs were scratchy and weak, the Omega's little chest heaving with little gasps and huffs. "Fuck," katsuki muttered, kissing Izuku softly. "Missed you, fuck...Didn't know how I stayed away for so long," Katsuki groaned, nipping Izuku's bottom lip.
"Y-You...nnh...really came back for me?" Izuku whimpered, another tear running down his cheek as Katsuki continued to fill his tenny pussy with virile cum. "Fuck, of course, I would. You're my fuckin' Omega—I wouldn't leave you," Katsuki growled, rolling his hips as he started to fuck Izuku again, making the Omega whimper and sob. Katsuki grasped Izuku's neck, squeezing lazily as he licked Izuku's crystal tears, the salty taste heavy on his tongue. Katsuki crooned and groaned as he rolled his hips hard and fast, knot tugging at Izuku's puffy cunt, still locked in the Omega's cunt. Izuku whimpered and bucked against his rolling hips, face wet with tears.
"Too...much! Too much, Kacchan! I-I can't..!" Izuku whimpered, face scrunching in pain and pleasure, sobbing quietly as Katsuki nipped and growled into his throat. "Nah, you can take it, Omega," Katsuki patted Izuku's bright red ass, the handprint still tender, and seared into Izuku's freckled ass. The freckles on Izuku's bubble butt popped in the bright red welt, standing out. Katsuki groped Izuku's ass, pulling him into his rolling thrusts, making Izuku sob and writhe.
"Good boy," Katsuki groaned, feeling his knot slowly deflate—the second it popped out, Katsuki slammed in hard and quick. Izuku squealed and locked around his cunt, eyes fluttering as his mouth popped up, seizing as he squirted hard, wetting Katsuki's abs. Katsuki grinned, a feral tint to his smile. "Fuuuck, that's it, baby, cum on my cock," Katsuki growled as Izuku sobbed, gripping the Omega's throat, holding his face still as he licked and groaned at the taste of Izuku's tears on his tongue. The salty taste burst on his tongue, making his cock twitch inside of Izuku's tight cunt.
Katsuki huffed and snarled as he shoved his second knot into Izuku's cunt, watching the Omega's eyes roll up into his head, those pretty sleepy jade eyes disappearing as tears streaked down Izuku's chubby cheeks, those pretty cheeks flushed a dark red. Katsuiki groaned— his goddamn balls were starting to hurt as he emptied his second load inside of Izuku, chest heaving. Katsuki huffed and panted, pulling Izuku close as the Omega twitched and whined, cuddling close to him. Katsuki carefully grabbed Izuku's leg, letting it flop over his hip as he cuddled close to Izuku. His cock throbbed and twitched, sensitive as fuck.
"Nn...Kacchan," Izuku slurred, head nestled into his neck, nose poking against his scent gland. "T-Thank you for coming back, nn.." Izuku mumbled, making Katsuki snort, squeezing Izuku's ass gently. "'Course, shitty nerd. Can't believe you didn't think I'd come back for your sweet ass," Katsuki snorted, jiggling Izuku's asscheek in his hand. "You're just a bonus," Izuku giggled into his neck, breath slowly evening out as he mumbled inaudibly, breath puffing softly against Katsuki's neck.
Katsuki stared at Izuku quietly, huffing as he kissed the Omega's face and grabbed the discarded bedding, throwing them over their intertwined bodies. Katsuki's cock, still locked in Izuku's slick cunt, twitched as he continued filling Izuku's pussy with his cum.
His Omega was finally back with him.
Fuckin' finally.
