Chapter Text

Izuku swam towards consciousness slowly. There was a desperate confusion as to why he wasn’t able to think in the first place, a sense of urgency, but why? Why fight against something so hard as he had to struggle now against this sticky version of sleep?

The decision was made for him when red slashes of pain lit up the inside of his eyelids as his head was roughly yanked back by the hair. He still doesn’t want to open his eyes, but someone is trying to say something and it feels important. 

“C’mon pretty little hero, I’m getting bored waiting here all by myself.” It’s said with a rasp and a smile, the deep voice swirling around his throat and chest, pressing in. It takes a moment before Izuku can recognize the pressure is actually a pair of hands holding him up and into a hug too tight to hide the predatory hint to their placement.

He slurs out a greeting, the closest thing to a hello with a question mark he can when his airway is being constricted and his brain feels squeezed even tighter.

“Good morning to you too,” he felt the man holding him up chuckle and relax his hold. “So polite, I guess you really are one of the ‘good’ guys.”

Awareness was inching through his body in fits and starts as his brain tries to catch up with each new sensation. His head is so heavy still so he lets it fall back onto the helpful man’s shoulder, nose tickling his neck. He smelled nice, campfire smoke and summer nights that made him want to snuggle deeper into that scent. Izuku tries to shuffle around but he can’t find his arms, resulting in him nuzzling into the stranger’s neck.

“You’re being so good little hero, I think that means you deserve a treat,” the rough hand on his chest groped at a pec, squishing the muscle in his hand, “do you want a treat, omega ?”

At that, Izuku jerked, alertness cutting through the densest portion of the fog clouding his thoughts.

“Oh? That woke him right up, look at his face–” the hand that had been just fondling his chest moved to lightly pinching the nipple, a laugh shook Izuku at the resulting squeak and attempt at wriggling back from the touch. “You’re that excited for a treat? Is that why you’re being such a good omega for me?”

“N-no–” he attempts to shake his head but the hand at his throat kept his face tucked into the stranger’s neck, pressed too close to the scent gland. He’s already so dizzy and the heady aroma only makes it harder to move away. Izuku tries to struggle, finding his arms bound behind him and arching his back with the pressure trapping them between him and the alpha’s chest. Izuku could discern it from the scent invading his thoughts now, deep and powerful. Demanding.

It makes him shake.

“Aw, don’t be shy omega. You deserve it,” a harsh tug on his nipple had Izuku crying out and it was quickly followed by another one, only this time, scarred and metal-studded fingers didn’t let go. He tried to move, get his legs underneath him, but his thighs couldn’t close. Why were they splayed so far open like this? He began to thrash as hard as he could with his thoughts still so thick, but the metal cuffs only bit into the soft skin of his inner thighs as the bar spreading him open refused to yield.

Searing lips came down on his own, cutting off the beginnings of a scream with no mercy. A tongue invaded his mouth, thrusting a chalky pill to the back of his throat before grinding against his tongue. His mind may not have been fully on, but his internal alarms were blaring at top volume. He reached for his quirk, desperate to end this quickly.

He felt nothing but the scorching hands and mouth on his body.

The cuffs weren’t only binding his wrists, they were trapping his quirk. He couldn’t breathe, he was fighting iron and losing.

The kiss broke off, loud and messy, but before Izuku could swallow down more than a single gulp of air, a stapled hand clamped down covering his nose and mouth. Dabi smiled down at him.

“Isn’t this a good treat, little hero? Come on, swallow it like a good omega and maybe I’ll let you swallow something else later.” He laughed, breath hot against his ear and Izuku thrashed. He wouldn’t swallow whatever this pill was, he couldn’t. But he also couldn’t breathe.

–

Dabi leaned down and pressed a kiss to his forehead in a teasing sort of affection before pulling back to watch his prey struggle in his arms a few moments longer. The omega in his arms was trying desperately to jerk out of his hold, attempts weakened as his air ran lower and lower. Big green doe eyes were wild and bright with fear, pupils dilated with adrenaline. He was so pretty. He turned Izuku’s head, exposing the soft side of his neck where his scent glad was pumping out distressed pheromones as hard as it could. 

The good thing about omegas this pretty? Their scents were pretty too, even when upset and angry. The bitterness that poured out was sweetened to the smell of dark chocolate and Dabi loved it. Their scents would mix together perfectly, chocolate melting just that perfect amount in the summer sun, gooey s’mores roasted and smoked over a campfire. Dabi salivated.

Not just yet.

The League wanted UA and their baby heroes’s spirits broken. They wanted the Hero Commission on their knees whimpering. And what better way than the Villain son of the number one hero Endeavor mating All Might’s successor?

These hero schools had shown time and time again how they couldn’t protect their students; pupping the golden boy of the most notorious hero school in Japan would start riots calling for administrative blood. Coupled with the reveal of Dabi being the long-dead eldest Todoroki, the Hero Commission would face riots. He would show them the heroes were just as bad as the villains. Him, Izuku, and the adorable green haired and blue eyed pups they would have.

But first, Dabi had to show his omega he was worthy. He leaned down to nose Izuku’s ear, biting his lip to keep himself calm when the boy shuddered. So sensitive .

“ Swallow. ” He felt Izuku go rigid in his grasp at the alpha command, muscles tensed and holding still even as his throat was forced to swallow down the heat inducer. “See? Now that wasn’t so hard, was it?”

He kept his hand where it was cutting off the omega’s breath, moving his head up and down in a nod, even as the boy tried to shake his head no. Still so defiant after so long without air. Strong omega, pups will be strong. Strong enough to beat Endeavor. Dabi was his father’s son after all.

Now for the real treat, his omega had been so good, was still being so good. Izuku was still jerking in attempts to struggle. Dabi embraced him as best he could while also making sure he couldn’t breathe, taking in a deep lungful of air into his chest for the both of them. Something sweeter cut through the cocoa dark chocolate of Izuku’s fear. Mint and honey. Slick . He groaned in joy and arousal, running the hand that had been pinching and playing with one of those cute nipples the whole time down his freckled abdomen. It was all red and hard now, he would kiss it better soon. He would kiss every part of Izuku.

“My pretty little hero’s been so good for me,” his fingers skimmed farther, dipping down to meet the dark green curls between plush thighs. The resulting whimper made him giddy, “now alpha’s going to make you feel good too.”

With one finger he softly, so gently, began to circle the boy’s clit. The reaction was instant, Izuku had been fading, his attempts at breaking free weakening, but with the jolt of attention and pleasure he jerked hard. He tried to pull back from Dabi’s hand, only to grind that perfect ass back against his already hard cock. The omega froze in shock and Dabi’s fingers moved.

He had wanted to do this slow, bring his omega to the edge of pleasure slowly, carefully, like an alpha that could provide should for their first time, but Izuku just knew how to rile him up. He circled around the boy’s clit hard and fast, using the pressure to push him back to grind against Dabi.

“Oh fuck omega, I’m not even in your pussy yet and you feel so good. Look at you arching your back already, dripping and begging with your body since your alpha won’t let you talk just yet. Fuck, you’re such a good boy.” His hand was flying over the boy’s clit, the squish of slick sounding over Izuku’s muffled squeals. Dabi felt the strong abdominal muscles under his palm where he pressed down clenching, Izuku was tensing up, unable to struggle as his body locked up with his first orgasm of the night. 

“Gonna come for me already, hero?” He pulled his hand from Izuku’s face at the same time he plunged two fingers into his pussy, thrusting deep and curling his fingers while his palm ground down still on his clit. Izuku didn’t even get the chance to breathe in before he came, hard and silent with no air left in his lungs to scream.

–

Dabi didn’t let up after that first orgasm, finger fucking him through and past it. Izuku’s head was spinning from the mix of whatever had been used to knock him out, the mystery pill Dabi had forced down his throat, and the high of finally getting oxygen. Only, with every breath, whole lung-fulls of the alpha’s pheromones joined the toxic swirl inside him. The slick that had already embarrassingly lubed up scarred fingers nice and shiny was now squelching out of him in drips down his thighs.

The movement inside of him was harsh and fast, knuckles punching into him with every thrust as his clit was ground with a ferocity that had him seeing red. His thighs were still locked in aftershock spasms, completely unable to squirm away from the oncoming second orgasm the villain was determined to force out of him even if his thighs hadn’t been trapped in steel.

“What a good omega, you come so fast on my fingers, fuck– ” the cock grinding against his ass was a burning rod, god did his cremation quirk extend over his whole body? “Can’t wait feel you coming on my cock.” He slowly rubbed his fingers hard against his inner walls with each panting breath. The realization Dabi could feel his pussy fluttering with pleasure under his assault had Izuku desperately clenching his thighs in yet another futile attempt to close them, resulting instead on clenching down on the hand inside him.

“N-no, Dabi–” he could barely get a word out, the sound punched out of him before he could get through.

“That’s right pretty boy, say my fucking name when you come.”

“Don-don’t wa-ant to–” he was nearly thrashing at this point, able only to share his head back and forth in refusal.

“You don’t want to come? But I can feel you clenching around my fingers,” the burning fingers inside him stroked roughly and achingly slowly in emphasis. Burning kisses were lathered down his neck, smoke curling off the skin, sending sparks down his skin and pooling into his gut. Red arcs of electricity that had nothing to do with the quirk he couldn’t reach stretched taught within him. His back arched further against his will, thighs quaking, pulse hammering through his clit hard enough to barely need any more ministrations to bring him over the edge.

“Don’t want to c–” god he couldn’t admit, couldn’t say it, couldn’t give Dabi the satisfaction of hearing him. He couldn’t keep his voice from letting fucked out moans slip as he was thrust into over and over, but he could keep the words inside. Never tell Dabi he was going to come because of him or anything he did. He would swallow them down like the pill he could still taste on the back of his tongue. Push them deeper inside himself than Dabi could force his fingers. Thrust them inside hard, harder, right there–

Dabi’s hand stilled inside him and he wanted to scream. The pressure that had been building, the rising wave was halted, curled around him and pinning him in place with the inevitability that yes he would come, if only a moment more, a thrust aimed at just the right place, another hard grind against his clit. It would come crashing and world-shaking and take him, save him, from the reality of the moment.

“Oh my god, you really are painfully sweet.” A nip at his earlobe, a hot tongue circling his earlobe like fingers had his clit only moment before. “What a good boy, best boy.”

“Wha–?” He shook his head in an attempt to keep himself from moving his hips to fuck himself on those fingers. Don’t let him know. Don’t beg. Don’t break.

“You want me to come now that you already have? You’re feeling selfish being the only one getting loved on–” Dabi began to pull his hand out, the slick sound loud enough to squelch over the sound of heavy breathing in Izuku’s ear..

“No! Nononono!” And to what exactly he didn’t want to happen, he couldn’t say.

“My selfless little hero,” Dabi gripped his jaw with a wet hand, so hurried it could have been a slap had it not ended with the mashing of lips. He pulled off and set about smearing the slick and come over Izuku’s face, mixing it with the drool and tears he hadn’t realized were dripping down his chin. “Such a good omega, wanting to satisfy his alpha. Don’t worry baby, you can come. I want you to come, I want you to come until it’s all you know, until my hands, my mouth, my cock are all you can think about with that big beautiful brain of yours.”

And with that, a too-hot hand finally made its way back between his legs, gathering up the slick growing sticky oh his thighs. His orgasm wasn’t abating, it felt like one last touch would get him over the edge. He was so hot, when had he gone from chilly and naked to burning to match the hands that torturously traced only his outer folds? The skin exposed to the air, being left untouched, was prickling with gooey warmth pooling down down down within him to collect right in between his hips. Fuck, he needed that hand back inside him– no something more.

“It’s really starting to kick in now, god the face you’re making,” that traitorous hand left him wanting, spread and desperate and so wet, to angle his face up to the alpha. “You wanna come, baby?”

Izuku tried to shake his head no, the vow he had made before still burning hot enough inside him to feel it over the forced heat he was going through now. Dabi’s face took on a look of… concern? 

“I know you want to, look how you’re dripping–” metal staples scratched along his bound arms as Dabi twisted Izuku like a doll to look between his own legs at the drops of arousal not just painting his thighs, but actively running down them. “You want to come Izu, you can say it.”

“I don’t! I don’t want to!” He scrunched his eyes shut, trying to hide from the embarrassment of just how turned on he was, just how close to the edge. He did want to, needed to. But not like this. Not at the hands of a villain, begging for his own torment to continue.

Dabi simply pulled him back up and against his chest, doing so with more care than Izuku had thought the monster could. Strong alpha, strong, but also gentle to omega. 

“Who told you you couldn’t ask for what you want?” Pierced brows angled themselves sadly. “Do the heroes– did they do this to you?”

“ No! ” God his pussy was aching, thighs and abdomen clenching down on nothing in the hopes for any sort of relief from the heat that built and built.

“Izuku, you don’t have to protect them, it’s okay. I’ve got you now– we’re going to take them all down. We’re going to do it together.”

“That’s not! No! I don’t want to–”

Dabi buried his nose against his scent gland and sucked in a harsh breath, calming himself with the bitter scent of Izuku’s distress. Although, the scent of his arousal was so heady at this point the honeyed mint had to be cutting the bitter cacao dark chocolate, easing into omega sweetness. Enticing. 

Begging.

It was without words, but Izuku was begging all the same.

“They really did a number on you, huh little hero? You know, they almost had me too. But I’ve got you now, you’re okay. I’ll give you what you deserve until you can heal from their brainwashing. I– I didn’t realize we had so much in common. Fuck, I knew you were the one Izu, but this, we were made for each other. Let me take care of you baby.” The hands imprisoning him curled around his middle, crushing him back not to grind the white hot iron rod of the alpha’s cock into him, but to hold him. Hug him. Embrace sweetly. Alpha wants to take care of you.

Izuku keened and Dabi answered.

“ COME. ”

Izuku was gone, consciousness consumed completely by the surge. The tsunami that had built up and up and up as he watched and finally crashed into him, stealing his air and making his body a useless puppet being thrashed around by forces and muscle spasms beyond his control. His cunt throbbed with wave after wave, not stopping or fading as the alpha command held its power over him.

Then, in a moment, his muscles couldn’t hold him up anymore, he collapsed, head lolling forward and his chest pressing into the strong, scarred arms still embracing him. Dabi leaned him forward gently, whispering promises in his ear he couldn’t hear through the rush. Ass up, cheek to the rough floor and lovingly caressed, the pressure encompassing his whole body began to let up. He was swimming in his own mind once again, but this time he didn’t want to reach the surface. 

The pleasure flowed through his cunt, hot and dripping and so achingly empty. He had come the hardest of his life, the hardest he physically could, it should be impossible to achieve a higher pleasure than that which flowed freely down his thighs. And it wasn’t enough.

“ Alpha– ”

“Fuck yes omega,” Dabi threw himself over Izuku’s back, cradling his head gently with one hand so as to not scrape up his face on the ground below. Izuku wondered if he would lap up the blood if he did. “Anything, anything. Say it baby, say it.”

“C– come? ” At that, something eons larger, hotter, more satisfying speared its way into him at the same moment fangs tore into his scent gland, marking him, claiming him. Permanently.

Dabi pounded into him, strong alpha jaws clamped so hard on his neck he could barely breathe. Izuku was coming, it was like he had never stopped and never would. He was finally able to scream when Dabi let go of his throat, the drawn out sound going staccato with each thrust into his pussy. 

Everything in his mind was gone but the pleasure, the feeling. He couldn’t think, he could only take and take and scream. But it still wasn’t loud enough to drown out the barrage of commands Dabi was ordering into him with each slam inside.

“ COME. COME. COME– ”

It never stopped.

Chapter Text

It never stopped, it only accelerated.

“ Come. Come – fuck Izuku you’re so damn pretty like this– come. I’m going to make you feel this good every day because you deserve it, perfect omega– come. Come. Come harder. ” The alpha at Izuku’s back couldn’t keep his words to himself, spilling out of him unbidden in the same way Izuku’s squeals couldn’t be silenced

He was once again swimming, no, this time he was drowning. He couldn’t breathe, couldn’t get the muscles crushing down on his lungs to budge. The cock plowing into him filled him too much with each stroke to relax, it felt like he was choking on it. It was wonderful.

It wasn’t that his sight came back, it was that he was finally coming down from the hardest damn orgasm of his life enough to take in anything other than the abject pleasure overwhelming him and everything he was. The ability to process sight came back first, as a background to the all-encompassing crash. Then the realization his body had boundaries. He was not just this eternal feeling, he was something separate from the hazy floor he was pressed up against. Was it hazy because it was so close or because his eyes were rolled back? Was the world made up of endless jagged motion or was that the ragdoll way he was jerked back and forth.

“Fuck baby, when you clench like that on my cock it feels so good,” Dabi lapped up the blood seeping from his fresh mate mark, breath hot on his neck. Wait–

Mate mark?

Izuku fell back into his body and the euphoria of the come down from his orgasm made the terror all the more horrifying. An alpha had marked him, a villain alpha. Was still inside him–

“ Come. Harder. ” 

He screamed, unseeing. He was nothing but the feeling of the white-hot iron rod skewering him through and the desperate way his body clenched down again and again on the fire inside him. His legs couldn’t close, something was stopping them. He could only clamp down harder on the unforgiving cock splitting him open.

His body had tensed up, uncontrollable muscles arching his back into the pounding and lifting his head from the rough ground to project his wails as far as they could go. Let anyone with any hope of hearing him know just how hard he was getting fucked, raw, bound, and spread against his will on the floor by a villain whose gentlest touch burnt scars into his waist.

A burning hand caught his face as his body gave out yet again, sending him crashing back to the floor. Steam curled up where the sparks of blue flame met the soft skin of his cheek. He didn’t have the will to flinch away.

“Good boy, such a good boy for me, coming so pretty–” it hadn’t even been an alpha command, but Izuku’s pussy clenched and throbbed until he was choking. Coming just from hearing the word? How was this possible? How was he still so sensitive? He was being pounded into the ground like it wouldn’t stop until he’d been plowed six feet down. It should hurt. He should scream and rage and rip his alpha’s dick off with his teeth–

“Izu, baby, you’re already screaming. If you wanna swallow my knot so badly, you know I’ll gladly give it to you,” the smile in Dabi’s voice was palpable. God, had he been saying that all out loud? The piston of the alpha’s hips slammed to a punishing stop and Izuku desperately missed the motion.

When thrusting in and out of him, he’d had the chance to gasp in mouthfulls of air before it was punched back out again. Now, he felt full to bursting. There was no room in his body, no crevice he could store oxygen that hadn’t been stuffed to overflowing.

“Keep talking about my dick like that omega, and you’re gonna give me a complex. This muttering habit of yours is dangerous,” Dabi pulled out with excruciating slowness, laughing at the senseless babbles Izuku couldn’t help letting slip with the glide of inch after inch.

“Nn-” how was it that when he meant to talk his tongue got caught in his mouth, but his thoughts spilled out along with the slick down his thighs? “No!”

“No what, omega?” Dabi halted his exodus, grinding the head of his cock gleefully just inside the ring of Izuku’s cunt. “No don’t pull out?” He slammed back in, laughing at Izuku’s pathetic attempt at a squeal. 

“Can’t! Can’t take it!”

The villain held himself still, spearing him through with the full length and draped himself completely over Izuku’s back to whisper hot and devastatingly clear into his ear.

“Baby, you already are.” He ground his hips, straining Izuku’s insides. In direct opposition to everything he’d done, Dabi gently cradled his head, scraping his own knuckles against the stone beneath them to protect Izuku’s face. His other hand slipped up and around his throat, not to choke him again, but to coat his fingertips in the mixture of blood and claiming venom that dribbled from the mate mark on his neck like the come down his thighs. “You’re taking me so well, and you’re going to keep taking my cock until you know you deserve it. You deserve everything I can give you. Wanna know how I know Izuku?”

Izuku could only gasp for breath, desperate around the intrusions taking up all the space in his body and mind as blistering fingers pressed into the punctures in his neck in a mimicry of the burning rod spearing his cunt open.

“I know because we’re meant to be.” Dabi trailed bloody fingers sweetly down Izuku’s sides, petting him with a care that matched the sweet horrors he was whispering into his ear. “I wanted you before we even had a plan to take you. I saw that fire in you, that fire that burns in me. You fight for what is right, but you just don’t know what ‘right’ is yet. You want to change the world, my little hero, and together we will. We’re going to take our fire and burn it all to the ground so we can build it up perfectly.”

Dabi still wasn’t moving, wasn’t thrusting, was only painting bloody trails over his stomach, over his womb and pressing down down down, sparking lights across his vision. Why wasn’t he moving? Why was he making him feel the cock inside him in its totality? What happened to the relentless alpha commands to orgasm over and over, harder than he ever had before? Why was Izuku desperate to feel it again?

Izuku’s thighs, spread and held open by the stretcher bar, shook as he tried to rock himself back. The villain sucked in a breath above him and wrapped his arm around the omega’s middle to keep him still, pin him in place as nothing more than a warm hole.

“Just like that baby, that’s how I know. Not every omega will come-” Izuku came again, unexpectedly and squealing on Dabi’s dick, even as it burned motionless inside him, “just from an alpha command. And even fewer omegas, the rare ones, will always follow the first command their alpha gives them after claiming. Even when it isn’t a command. Just saying the word come- ” again, pussy pulsing and clit aching to be touched. The ministrationless orgasm and the heat singing through him from the pill earlier left him needing more, more than he’d ever wanted before, “will be enough to get you to come. I don’t have to do a damn thing. I can pleasure you endlessly. Because you were made for this. Made for me. Made to come like the perfect omega you are. Come, baby, come on my cock.”

And he did. Again and again. Whimpering and whining and desperately trying to move his hips, to free his hands from the cuffs behind his back to stroke his clit and finally get an orgasm that made him feel complete, satisfied. He needed something more, everything more to satisfy this ache. 

His forcibly induced heat rocketed through him, the blood in his veins pumping too hot and causing every part of him to tingle. Sparks scorched along the areas Dabi touched like flint rocks being struck. The white hot rod searing inside him wasn’t enough, not without motion, friction, a spark. He needed his clit stroked. He needed his alpha’s cock pistoning into him like it had what felt like ages before. He needed a knot.

“Alph-alpha-”

“Yes, my omega? Want to come again? You will. Come. Come.”

“No!” He was scrabbling best he could, raking blunt nails against the body pinning him down in an attempt to grip the flesh and pull, push, anything to get some movement, get his alpha to be the one to come. To fill him fat and full with come that would finally quench the fire inside.

“No? No you don’t want to come? But you deserve to come, and you look so pretty when you come. Come on baby, come again for me.”

Every part of him was shaking, awareness tunneling down until he could only focus on the need, the lava in his guts, and the hyper sensitivity of his pussy. It was all he was anymore, all he had become was a molten cunt to fuck and his alpha wouldn’t even use it as anything but a cock warmer.

“Listen to you come, god Izuku you sound so good when you come. Come harder .”

He was screaming, sobbing. Every time he opened his mouth to plead for the knot he needed, he was forced to come again without it. Hot slick ran in rivulets down his thighs to make his knees slip on the floor, almost sliding free into some sort of movement, but Dabi’s hold was too strong to let his legs giving out jostle his dick even slightly inside him. He stayed, pinned open and coming unceasingly.

The hand cradling his face crashed their mouths together, finally giving his pulsing pussy a break, a chance to come down from the relentless orgasms that rocked him. Dabi’s tonge licked its way into his mouth immediately, hot as his cock and filling Izuku from both ends. He was entirely encompassed by the alpha, held tightly enough in his grasp to be used as nothing but a toy. Only he wasn’t being used. 

Wasn’t being fucked.

He bit down on Dabi’s tongue until the villain pulled away, blood spilling from his mouth to join the puddle already formed by Izuku’s mate claim. He wasn’t begging anymore.

“Alpha! Knot!” 

“Omega- fuck!” Dabi groaned, quickly turning the sound into a smiling snarl as he nuzzled into Izuku’s scent gland. “As you wish.”

–

Dabi really had planned on easing his omega into this. He’d planned to finger him open softly; starting him out slowly with gentle circles of his clit, a pinch or two to make him cry all prettily. Get those big green eyes sparkly with tears until they spilled over down his cheeks for the alpha to coat his fingers in to slide wet and easy into his pretty little boy cunt. Rile him up until he could only focus on each finger sinking into him one at a time to savor the stretch, the start of their first time. Have him coming on his hand enough times to get it through his brainwashed head that this was what he deserved. 

Only then would he fuck him sweetly, claiming him for his own as they both reached a climax high and heavenly and right out of the steamy romance books he’d found in Izuku’s room to learn more about his future mate. 

He had been too closely watched at the dorms, UA and their asinine “protection” policy keeping them apart. But his home? Mrs. Midoriya Inko – his stomach twisted with something akin to joy when he remembered he could call her “mom” now too – couldn’t keep a discount house plant out of her house, let alone an upper member of the League of Villains. 

It had been nothing to pick the lock. He had his omega to learn about. And while it was incredibly fun to face down his future mate on the battle field, eyes wild and feisty and strong, he wanted to know more. This was the omega he was going to spend the rest of his life with, the (other) father of his children. The children who would grow up to take down Endeavor and everything he had ever stood for.

And finding his little hero’s collection of spicy romances and heat toys? Dabi had gotten off to that for months as he’d planned out their future together.

He’d wanted – prayed – his and Izuku’s bond would be one strong enough for his alpha commands to work, period. And then? To hold his omega in his arms and have fate deliver him one so receptive, so well matched to him he would orgasm to a command alone? The alpha’d just had to see how far he could take their bond; try speaking the trigger word rather than putting any power behind it. Just to test. Just to see. 

Destiny tasted like mint chocolate on his tongue and sounded like heaven on his cock.

He encompassed his omega, not just on top of, but around on all sides, curling, shielding, protecting his omega how he deserved to be. Giving him the pleasure he deserved. Impress omega.

He’d watched Izuku cry, enchanted, as he made him come again and again with his voice alone, with their bond alone. His pussy clenching rhythmically down on him each time he came had Dabi fighting against popping a knot just like this. 

He’d meant to be sweet, he really had. But he was a villain, after all. His little hero sobbing and begging on his cock for more even as he came himself into a drooling mess had just been too cute to pass up. He watched, enraptured by the faces his omega made every time he writhed, whimpering to get some sort of friction from the dick inside him. The tracks of tears and the cum Dabi had slathered on his cheeks earlier only made him prettier.

And then Izuku had surprised him. His perfect little omega stopped begging. He demanded Dabi’s knot.

He was just so good. Of course it wasn’t enough for him to be the only one coming. Strong omega cares for you.

Dabi didn’t bother holding himself back any longer and sank his fangs back into the claiming bite. He’d had Izuku coming and crying so long the blood had begin to clot, but now it was mixing with the sweet little nip on his tongue. Connected through fangs in flesh, cock in cunt, and bonds in souls. Connected in all ways but one. 

He pulled his hips back and slammed forward, slick squelching out in a sound he wanted to hear over and over again. He repeated the motion, using the grip of his jaw in his mate’s neck to hold the omega still as he fucked him.

Blood boiled into his mouth, searing his gums with the strength of Izuku’s heat. He bit down harder, snarls tearing their way out with each pounding of his hips. The world was entirely made up of the soft flesh crushed in his jaws and the cunt fucked into submission by his cock. He would hold his omega down and fuck him full of his knot and pups and not stop. His omega would grown swollen under him, overstuffed with come and plugged by a knot that felt like it would never abate.

The thought of Izuku, caught tight and unable to crawl off of the cock pupping him but trying to anyway, just wind up coming yet again from the tug of the knot in his abused pussy had Dabi’s orgasm crashing through him. His knot inflated, faster and fatter than it ever had before.

Izuku screamed, he roared.

Chapter Text

It was the hardest Dabi had ever cum. 

His fangs were grinding deeper into his mate’s little neck in time with the knot locked inside his cunt, practically fucking the wound with his teeth. The alpha was beyond words, beyond the human part of him that didn’t want to get off to the image of Izuku fucked through every hole and opening new ones just to keep going. He saw holes torn and drilled into those plush thighs, the femoral artery pumping hard and fast to fill the space with blood and mixing with cum there to the pretty pink of his omega’s blush.

He saw the strong stomach, guts rearranged literally, soft and squishy and ravaged beyond ever fitting back under the skin. His alpha told him to let go of his mate’s throat and sink his teeth into round and chewy cheeks. He could bite through the soft meat there and fuck his face in a way no one else would ever dare. In a way no one else ever would.

Izuku was his. His to have and hold and fuck and consume .

It was a disgusting thought. It caused another wave of full-body pleasure to seize him by the spine and force him into spasms the way he had forced Izuku through his overwhelming orgasms all this time. His hips bucked hard, dragging the omega trapped on the knot across the floor scraping up those now well-bruised knees and cute omega tits. As soon as he could he was going to spin Izuku on his cock so he could lick the blood off those bouncy pecs like it was the milk he dreamed of sucking out of them.

All he had to do was get his omega pregnant first. Fuck, he could alternate between lapping up omega milk and sucking on his cute little clit, see what tasted better, see what made him squirm more.

Until then, pinching with just his fingers would have to suffice. With the way his omega shook under him, he was in luck. He was going to suck on those tits until his little heroling learned how to come from them alone. 

What felt like a torrent of cum burst from him as all the ways he could pleasure his omega and how good he would look with scars spelling out Dabi’s name for everyone to know who he belonged to. Right in the soft skin over his womb, branding it with the blue-hot flames he would use to protect his mate at all costs.

He couldn’t help it, he was snarling into the mating bite to keep himself from ripping and tearing, he would not break Izuku on their first time. Not until he’d trained his omega how to take it all. He would regain control over his alpha. He curled his fingers into the soft stone beneath them, fuck he must be entering a rut from Izuku’s heat for it to be this easy to carve rock, letting his claws bury themselves deep in the ground rather than his omega’s flesh. His omega.

His omega, marked and ravished and knotted. Dabi bucked his hips again, just to tug on their connection, to drag his omega by the cunt across the floor and prove to himself that nothing could separate them now. He couldn’t hear Izuku screaming in pleasure anymore, his own blood was rushing too fast in his ears. That, or his poor little hero had passed out from the intensity of being knotted for the first time. 

Of being bred senseless.

And this was only their first time, their mating night. Dabi knew it was antiquated these days, but he wanted a traditional marriage too, not just a mate mark. Matching rings and matching scars on their scent glands. Brands of his hand prints all over his omega’s freckled skin. His alpha’s name scarred into his flesh, fuck maybe one day even his bones for everyone to always know who he belonged to.

The thought had him pulling his teeth from his mate’s neck, blood and claiming venom running hot out of the ragged holes. He’d intended to check the mark, gazing lovingly down at their soul bond, but instead, the slow bloody seep from the mark grabbed him by the knot and pulled him back into the gutter. 

That’s how his cum would pool out of Izuku’s ravaged pussy once his knot finally went down. Slow and gooey and thick as it mixed with the omega’s own slick. He could eat him out like that, tasting their combined pleasure all while bringing him even more. He’d suck on that cute little clit until it couldn’t come anymore, draining him completely of everything. And then he’d knot that cunt all over again, emptying his womb just to fill it over again, pump his pussy over-full making his tummy pooch out with the sheer volume of cum. He could even plug him up with a toy, leaving Izuku to suffer through being stuffed until he cried and begged Dabi to empty him, not knowing it would just be the beginning of an endless cycle. 

But a good alpha provides, he would need to feed his little mate soon. And what better than the high-protein meal between his legs? Drinking his alpha’s cum would be good for their pup anyway, dense and rich as it was. God, there were so many ways to fuck his new mate.

He wrenched his eyes from the oozing mate mark to take in Izuku’s lips. Red and ravished with beautiful lines of drool dripping down. They would look so good wrapped around his knot. Later. They had time. They had the rest of their lives.

Moaning in excitement, he ground his hips in circles, relishing the inadvertent twitches his omega’s body gave where it was slumped boneless and defenseless under him. Dabi leaned back to sit up in a more comfortable position until his knot went down. Izuku was completely supported by their tie, so exhausted from cumming his hips were only staying up due to the knot he was pinned by.

Like a butterfly specimen , Dabi thought. He hadn’t expected love to make him poetic, but then, he hadn’t expected love from his mating in the first place. He was his father’s son in all the worst ways. He’d been raised to fight everyone else around him into submission, to be the top alpha in every situation. Enji just hadn’t expected to be one of those prostrating themselves before him. Foolish man. 

It wasn’t Dabi’s fault, he was just living the way his father raised him. You best those who think they are stronger than you, pound them into the ground over and over until they know their place.

Izuku had never thought he was above Dabi. Like a good omega, he’d never thought he was above anyone. Dabi had watched the way he stuttered through small talk with fans who stopped him on the train. He had to know he was famous after the sports festival, and yet he’d been so genuinely surprised each time, smiling and blushing. 

Dabi had tracked his search history on his computer and phone with the fun little app Shiggy had found in one of his endless video game discord servers. Originally it was for nefarious purposes, getting more information about UA and its plans, and then getting more information on how to best keep his omega contained as the League enacted their plans. Dabi had, of course, watched with manic glee the porn videos and smutty ebooks Izuku had searched up. It was expected of teenage boys and only served to show Dabi he had a good omega who could, in time, match his kinks at the very least. 

He was shy with exploring more hardcore things, preferring romantic scenes to start off and slowly working his way into harder and harder territory as he rode his own hand; the villain had spent night after night watching along with his now-mate, jerking himself with the question of at what point in the video Izuku would come, boy pussy clenching down on his fingers while his toes curled and back arched. 

But he spent so much more time on volunteer websites. Online volunteering wasn’t something Dabi had considered before, but his heroling really did it all. Free tutoring. Omega mentorship for pups just presenting and seeking guidance from someone closer to their age for all the awkward questions. Archiving and digitizing old hero databases. Hell, he even had extensions on all his search engines that would donate money to anti-quirk discrimination funds to passively raise money for those less fortunate than him with his golden quirk.

He knew so much about quirk discrimination, it took Dabi’s breath away. He knew about the cracks in their hero-centric world. He worked to become a hero because he genuinely wanted to help. It was so sweet and so, so naive. He still thought he could fix it from the inside. 

He needed his alpha to show him.

He gathered his limp lover in his arms, cradling him to his chest through the tremors that came with being so over-sensitive and over-stuffed. To his delighted surprise, Izuku let out a little whine.

He was still conscious.

Strong omega. Strong pups.

His omega’s heat had just begun, thanks to the pill Dabi had forced down his throat. He was going to keep him completely sated. It was his duty as alpha.

He wiped a tender hand across his mate’s face, gathering tears and drool to lube up his fingertips before bringing them down, down to lovingly rub his clit. The whine increased in pitch.

“Don’t you worry baby, your alpha’s got you and he’s going to keep you knotted and stuffed through your whole heat, and then some.”

In response Izuku could only turn his face into his alpha’s neck to nuzzle the scent gland there, purring and whining intermittently along with Dabi’s stroking of his clit.

“Yeah, Izu? You like my scent? You like your alpha’s scent?” The omega may have been conscious, but Dabi honestly wasn’t expecting him to be capable of understanding anything but alpha commands with the glazed look in his eyes, but he was pleasantly surprised.

“Bonfire,” it was soft and small, the whisper only audible because his mouth was already so close to his ear.

“Yeah omega, bonfire. Such a good boy,” he would have continued, something along the lines of answering your alpha even when you’re so tired or other meaningless praise, but the pussy around him clenched down hard. “Oh? You like being called a good boy?”

Another clench and whimpering nod answered him.

“Use your words, your alpha needs to hear you.”

Watery green eyes looked up at him, all the fight from earlier dissipated with the knot plugging his pussy. Fuck, Dabi loved these swings. The omega thought that he could dangle a golden opportunity like a praise kink in front of him and snatch it away without punishment. Cute.

He couldn’t wait to show him how stupid he was.

–

Izuku blearily looked up into blazing blue eyes. His alpha had just asked him something, but he could barely hear over the pounding of the blood in his ears. 

The hand at his clit lifted, dragging softly up his belly and leaving a sticky trail of slick as it traveled. He crooned, that hand had felt so good, why was his alpha taking it away? Hadn’t he just said he was being good? A good omega?

The dark-haired alpha brought the hand up to his own mouth and began to lap up the juices he’d fucked out of Izuku all while the knot buried in his cunt continued to pulse inside him. He keened, needing those talented fingers back, they had felt so good and his alpha had even praised him! He was being a good omega!

“As cute as those omega sounds of yours are, I asked you to use your words. Do you like being called a good boy, Izu?’

Izuku keened and nodded, moving his hips in circles to milk more come from his alpha. He loved being a good boy, wasn’t he being such a good omega taking his first knot so well? Wasn’t he so good for making his alpha knot his little boy cunt like a good omega was meant to?

His alpha frowned and Izuku’s stomach plummeted. What had he done wrong? Had he come too many times when his alpha hadn’t? But he had said–

Smack!

“ Ahn! ” his clit throbbed.

“I said–” smack!

“Hng!” His clit!

“Use,” smack!

“Ahh! Owie–” his alpha was spanking his pussy!

“Your,” smack!

“A-owie! N-no!” And it hurt.

“Words,” smack!

“Nooo! Alpha!” He tried to writhe, but all that accomplished was tugging on the knot in his cunt, practically fucking himself on the huge intrusion.

“No? You don’t want to do as your alpha says?” A burning hand grabbed him by the throat while the other took his swollen clit between two fingers almost gently. A threat.

“N-no, please don’t!” Squirming only ground his alpha’s knot into him harder, so large and overwhelming he saw lights dancing across his vision.

“Don’t what? Say it clearly, omega.”

“Don’t pinch!” Not his clit! It was throbbing with more than arousal between his alpha’s fingers. He knew how strong they could be, the bruises they could leave.

“Then tell me, Izuku, with your words. Do you like being a good boy?”

“Yes! Yes, I like being a good boy– AH! ” Another searing smack, this time followed by a rough fingering of his clit.

“You wanna be good for me?”

“Yes! I do I do–”

“Then come .”

Izuku’s entire body convulsed with the power of the command, a full, virile alpha command to orgasm. It was lightning up his spine with waves and rolls of thunder shaking through his veins. He could feel his pulse all the way down to his fingertips, trapped and bloodless as they had been bound what felt like forever ago. But this was fire in his veins; his blood was hot, boiling under the skin that made contact with his alpha’s. It felt like he was running, had been running his entire life, that desperate for air and heart pumping painfully fast, exhausting past anything he’d been put through before.

His cunt convulsed around the knot inside it long after he lost consciousness.

Chapter Text

Dabi eased his omega down to the ground. Poor little thing had worked so hard to be so good for him. Too bad Dabi was a bully. Izuku was going to get his pussy slapped no matter what happened, finding a legitimate reason to punish him just made his squeals ring out all the sweeter in the alpha’s ears.

He trailed a hand lovingly over his mate’s ass, pulling and kneading at the cheeks to get the perfect view of his knot plugging up a red and abused cunt. God it was so fucking hot. Izuku was still unconscious, surely Dabi could have a little fun until he woke up?

He was barely able to pull back, but watching the bulbous knot stretch the skin even tighter and feeling those walls trembling around his dick was mouthwatering. He kept knotfucking, using Izuku as nothing more than a hole to stretch, grinding harshly into the omega who spasmed in response. 

Small whimpers and snuffles filled the air in between the staccato beat of skin clapping. Izuku wasn’t fully awake, the sounds were being pounded out of him. When his heroling woke he was sure to still be deep in the throws of his heat, they could try something new.

The thought had Dabi smiling softly, gazing lovingly down at his mate. Every position would be a new one for Izuku. He was a virgin, of that he’d made sure. He wanted no other alpha to come in between them, beat him to the punch of pupping this gorgeous omega. No one to crawl out of the woodwork to claim his beautiful kits as their own. A paternity test could only do so much, what with his younger brother being Izuku’s classmate. If he stepped onto the scene pretending to be the sire, claiming he’d had a chance to stuff what was rightfully Dabi’s full of his own cum, it would be difficult to prove and the heroes would have an easier time of stealing Izuku back.

Of course they would come for their golden boy. It was what the League had wanted him for in the first place, to bring the heroes to their doorstep and then their doom. To open the door wide for All Might and all the cameras to come with to see his little mate smiling angelically, holding their pup. See what had become of the future of heroes.

At long last, his first knot of the night began to subside. He could feel it in the lessening of the tension around the knot as he continued to luxuriously grind into his omega. Pulling plump cheeks apart once again to watch enraptured as rivulets of alpha cum started to dribble out of his mate’s overstuffed pussy. It was still stretched tight by the size of his cock, but the sheer volume Dabi had filled him with was too much for the boy to take all at once.

Good alpha, omega will be pupped for sure. 

He smiled. An omega as responsive to his alpha as Izuku was would definitely be easy to knock up. That didn’t mean he was going to stop. 

Gently, lovingly, Dabi began to undo the harsh straps binding freckled arms. He rubbed at the sore marks where the cuffs and spreader bar had bitten into soft skin and maneuvered Izuku out of the presentation position so he could hold his mate sweetly to his chest until the knot subsided. 

When it finally did he flipped Izuku over onto his back and spread his legs to watch the cum seep out. He looked beautiful like this; swaths of cum and tears painting his peaceful face, blood and mating bond venom dry and flaking from his neck, and last but certainly not least, the numerous little burns and hickies and bruises down that beautiful muscled torso. Abdominal and thigh muscles still quaked with strain. A trail of claw marks lead down to the green curls gone darker with cum and slick he’d happily spend the rest of his days buried in. 

And then his boy pussy. Clit flushed red and raw from a savage spanking, glistening wet lips hot with slick, and a steady stream of thick, viscous cum leaking from that sweet little cunt.

The alpha was salivating, spent cock valiantly attempting to stand again. Instead he reached over to grab his phone and open up the camera. He took dozens of photos. Izuku’s unconscious face. Izuku’s mate mark. Izuku’s pinched and swollen nipples. And most of all that well bred pussy. The puddle of cum as it grew, spilling out more and more. His fingers sliding in, cum squelching out around them. 

It wasn’t enough. He switch to a video where he finger fucked his omega, driving three fingers in and out meanly as Izuku cried out in his dreams. Perfect boy pussy convulsing in yet another orgasm, squeezing out more of that never ending stream of seed with each contraction and thrust. He held the camera from all angles, zooming in on the minute facial twitches, full body shots so every viewer would know for certain just who they saw being fucked, and close up on that cunt taking his fingers so well. He could have done this for hours, but Izuku began to stir. He was his alpha now, he had a job to do.

Fucking like animals was hot and Dabi would most certainly be pinning his heroling down on the bare floor again, reinacting their first time over and over, but now that his heat had activated fully the omega would need a nest. He quickly selected a few full body and mate mark photos to send to Shigaraki as proof, okay and maybe the video too but it was just too hot and he needed to brag, and lifted his omega, nude and dripping, and carried him up out of the basement. 

It was time to show his new mate his den.

–

Izuku came to fuzzy and warm, like a sift glow was added onto his vision that made every light more haloed and diffused. The unidentifiable shapes around him formed whole deserts of soft hills in all different greens and blues until they came into focus as blankets. Nesting materials. And even better, they were the same color as his and his alpha’s eyes.

Good alpha provides for us.

He set to it, weaving and tucking the deliciously scented blankets around him into a nest worthy of his mate. The pile seemed almost unending to his omega’s extreme delight. Izuku had spent the few heats he’d had so far desperately scrounging and embarrassingly asking for scented items from his friends and family. Now he was fully, without begging, surrounded by his alpha’s scent. Only his alpha’s scent.

The ache in between his legs was steadily growing as he built, the warmth of his cunt distracting to the point he would catch himself humping blankets he’d grabbed originally for nesting. He couldn’t help it! His head was so fuzzy and his movements were becoming clumsier and clumsier and there was the deep crackling campfire scent of his alpha all around him that made his thighs clench together instinctively upon breathing in.

But he had a job to do! His alpha was off gathering supplies to last them through the rest of his heat and had left Izuku to make their nest. He wasn’t sure why he hadn’t built a nest before his heat had taken him, but his alpha was the best and had knotted his needy pussy there on the ground even before Izuku had shown him how good of an omega he could be.

Only, just thinking about his alpha’s knot made more slick slip from him while his hips jerked over blue sheets. He bunched another between his legs and ground down, trying to sate himself while weaving more blankets around himself. He rocked his hips side to side slowly, letting the slow pressure and uneven texture of the blanket rub across his clit and messy cunt. Each rock sent white sparks of pleasure shooting up behind his eyelids until he realized he’d been humping the blankets and whimpering without continuing his nest. His alpha couldn’t come back to a half completed nest after going off hunting for provisions! His alpha deserved the best! 

Izuku lifted himself from the blankets, sticky strings of slick still trying to drag him back into the throes of pleasure. But no. Izuku was stronger than the thrumming of his clit. The better his nest was, the more pleased his alpha would be. The more cum he would stuff Izuku with.

The thought had him licking his lips.

He made it only a few more minutes before he was writhing, hips working as desperately as his hands. He’d only made more piles to hump rather than strengthening the walls and was working to slather them in his scent and slick. Where was his alpha? He needed more of him, more of his scent, more of his touch. So much more of his cum.

Izuku burrowed down into the nest he had created, whining as he got closer and closer to the strongest scent of his alpha. Finally, he unearthed a pillow, firm and well used. These scented blankets were a godsend, but they were so sterile, so new. This pillow had been slept on for ages, soaking up the smell and flavor of his alpha. It was perfect.

Izuku’s next destination was even harder to get to, with his instincts screaming to not leave his nest for any reason, but the laundry bin was calling to him with the siren song of campfire and hot summer nights to mimic the heat dripping down his legs. It was only a few steps away but it was agony. His pussy was so hot and empty without even the scented blankets to rub against. One shaky footstep after another brought him almost within reach of his goal, only for his legs to give out. He scrabbled for a hold, catching himself on the side of a desk that by the smell, his alpha had spent quite a bit of time at. He was bracing himself on the edge, whimpering each time his needy hips jerked, seeking something, anything or his alpha’s to rub his cunt across. God he needed that cock in him, but he had to be a good omega and wait. His alpha wasn’t leaving him empty and wanting out of anything mean. His alpha had been so good to him, making him cum over and over with only his commands.

Just the memory of the feeling of coming had Izuku bracing himself for the onslaught of feeling. It had been so easy, so constant with his alpha that not coming now felt like torture. A few more steps. He could last a few more steps without his alpha’s scented things between his thighs. He looked towards his goal, the laundry basket, full of the ripe scent he craved. Sweat-soaked work out clothes, until finally he brought his cunt to the corner edge of the desk and reached.

His hand closed around a shirt at the same time the desk corner nudged his clit. A spark of bright red lust lanced through him and he ground down again, pulling the scent-drenched shirt to his face to huff. All the self control he’d managed since he woke up shattered with the all-encompassing smell of a wild, raging campfire and he humped the corner of the table desperately.

The pheromones had his mind swirling, the room spinning as he huffed the fabric and frantically rubbed his cummy clit over more of his alpha’s belongings. Alpha was his. This den was theirs and everyone who came too close would know to stay away.

Cum spurted from him, dripping down the desk onto the floor. Izuku moved to the chair, the wardrobe, even standing on some books to slather himself on the door handle. But it was when he finally made it over to the laundry basket that his omega howled, needy in the utmost for his alpha, not just his scent.

He dragged the entire laundry basket over to his nest awkwardly as he also couldn’t stop humping it and pulling more clothes out to scent. By the time he made it back to his blue and green oasis nearly a quarter of the contents were wrapped around his neck.

He wove them in with one hand, the other flying over his clit and smearing his mint chocolate scent everywhere he could. When he finally placed the last shirt, he rolled onto his back to finally free both hands. One was still grinding down on his clit harder than he had ever dared before alone in his room, his alpha had trained him so well so quickly! 

His other was plunging slim fingers in and out of his sloppy cunt, at first three but it wasn’t enough, wasn’t anything compared to his alpha’s cock. Not even four was enough. And!His hands were too small, fingertips unable to even graze the myriad of spots inside him his alpha had shown him. He was so desperate; the orgasm was building but without enough pleasure from how he was touching himself. It rolled over him, legs shaking where he had splayed them open, hands working furiously grinding and thrusting, mouth agape with wanton moans and despondent omega sounds pouring from him.

The pressure behind his eyes was immense, the growing and roiling of a storm inside him. The fingers in his cunt crushed by the tightening around them, pinning them in place like a deer in headlights. His head lolled to the side, drool spilling onto the cum-slathered nest. His nose found his alpha’s pillow and he buried his head into it, giving one last urgent thrust of his hands and exploded, the storm began with a downpour. 

Izuku squirted, cum shooting out of him and drenching the nest in his scent. Eyes rolled back as the thunder and lighting of his heartbeat and pleasure rocketed around his body, from his cunt spasming and pushing yet more cum out with each jerk, to his toes curled so tight it hurt, to his lungs, crushed with the pressure and locked unable to breathe for the eons the orgasm shook through him.

He collapsed, fingers slipping from his hole to drip cum over his already soaked thighs. He shook, eyes still rolled back and gasping for air. 

He’d done it. He had thoroughly scented his nest. Izuku was gone, the heat haze descending upon him fully. He needed more.

The omega weakly gathered himself as best he could, taking a shaky but deep breath. Finally, he crooned for his alpha.

Chapter Text

Dabi had Izuku’s knees up by his ears and was fully sheithed inside his hot cummy cunt before he was able to process what he’d had the pleasure to walk in on. 

“Fuck baby,” and oh how Izuku flushed and smiled up at him at the pet name; well as much as he could while being completely fucked out of his cute little head, “scented our nest so fucking well. What a good boy.”

Beneath him, Izuku keened and came to the praise, shaking and adorable. Green eyes hazed over with pleasure, tears brimming over with each harsh thrust and tiny tongue peaking out over plush and bloody lips. They looked delicious. He leaned down to taste, spearing the boypussy through completely as his hips slowed, tongue out and licking a long stripe across that wobbling lower lip before diving in and devouring. 

His moans tasted even better than they sounded. Dabi thrust his tongue in, rubbing along small but sharp omega fangs just to feel the shadow of his heroling’s bite. The boy tried admirably to keep up, kiss him back even with all his inexperience, but the cock stirring his guts kept forcing pleasured cries and mewls from his mouth, leaving him panting slack jawed as his alpha explored and took how he wished. 

Well, if he was going to keep taking those heaving desperate breaths with his tongue out, his alpha would grant his wish. Dabi latched onto his omega’s tongue, sucking hard and luxuriating in watching glossy green eyes cross in pleasure. He was so damn sensitive, if this was how he reacted to getting his tongue sucked, how hard would he cry when the alpha sucked on his clit?

He nipped Izuku’s tongue gently before sliding his own along the soft underside of the muscle as if it were a cock. He was the one who had to teach his mate how to give proper head. From the tracking apps he’d put in his omega’s computer, he knew the boy watched plenty of alphas knotting their bitches’ mouths, catching behind their teeth and forcing them to drink cum until it deflated. Dabi had coated every photo he had of his future mate with his cum at the thought of Izuku down on his knees, mouth locked onto his knot, choking and guzzling. Getting him started practicing with his tongue would be good for the boy.

Changing his pace to an even slower grind, he thrust his tongue into the boy’s mouth, fucking it in time with his pussy. Izuku choked in shock, throat constricting reflexively around the intrusion before relaxing submissively like the good omega he was. Kissing his little hero really was the best.

Breeding his mate from behind while he’d been bound had been hotter than his own cremation quirk, but humping into him from this position, getting to watch every change of his face as his body was ravished? Swallowing every gasp fucked out of him? Simply getting to keep their open mouths pressed together as they crushed together too intensely for Izuku’s cock-drunk little brain to do anything but take and take and take it all.

The alpha pulled back to watch where they were connected, growing knot pulling at fucked red and raw walls. He pulled out, warmed through his cold, dead heart all the way to his toes when Izuku whined up at him. He kept the omega bent in half, pinned down by his own shivering legs. Fuck he was so bendy. They would certainly be making use of that information.

“A-alpha?” and oh how that sniffle made Dabi preen with pride. Izuku tried to wiggle his hips enticingly even with his restricted range of motion, struggling against the clawed hands caging him in.

“ Stay ,” he commanded, watching as his heroling stilled beneath him. “Good boy. Don’t worry, alpha will knot your needy pussy soon, he just wants a good look.”

“Nnnn-not needy!”

“Not needy? You think your little pussy here isn’t needy, omega?” Dabi grabbed his cock by the base, drops of Izuku’s slick dripping off and back down onto where they’d come from. “You think you can finger your own sopping hole while your alpha is trying to gather provisions just a stairway away and not be a slut?”

“Slut?”

“Yes, my little heroling. Omegas who matsurbate until they cum so hard their pussies learn how to squirt are sluts.”

“Didn-didn’t mean t-to squ– squ–” Izuku trailed off, too embarrassed to own up to what he had done. Well, his alpha couldn’t allow that, now could he? Dabi slapped his dick down right on that defiled clit. Izuku came with a squeal, muscles tensing as he instinctively wanted to pull away but the alpha command to stay held him as the older man smacked his cock down on the sensitive bud again and again. Slick and cum splattered over the backs of Izuku’s thighs, decorating the hand-shaped burns and bruises like stars.

“Say it, slut, say what you did.”

“I! I came! Ahh- alpha, I came! Uhn! ”

Dabi paused in his assault with his dick, instead bringing his closed hand down hard on the whimpering boy’s ass. It jiggled too deliciously to not repeat the action, frothy cum still pooled from the boy’s first knot sloshing from side to side inside his now gaping hole. Again he brought his hand down sharply, eyes locked in on the abused pussy’s desperate twitching. His omega liked being spanked, no matter how he tried to protest. A glistening drop of precum splashed down with every “no, alpha,” “please stop,” and “ it hurts, ” he was gifted. He treasured each one.

“You didn’t just cum omega, tell me what you did. Confess ,” he brought his hand down harder than before, right on his boy’s cunt. Izuku screamed out his orgasm and it was music to Dabi’s ears.  How had he managed to score the omega that came from getting his pussy spanked?

“I squirted, Daddy, my slutty omega hole squirted touching myself to your scent!”

Oh. That– that did something. Unlocked a new place in the man’s mind, somewhere he would never have dared venture before Izuku. But now the door was thrown open, blasted off the hinges.

“Say that again.”

Izuku did so, barely managing around confused sobs.

“My slutty omega hole squirted touching myself to your scent, I did, I really did, Daddy! Look at our nest, needed your clothes. H-humped piles of them l-like a slut.” Their position had the omega locked in place, but he was frantically trying to look over and past his own legs to find proof, some shirt of his alpha’s he’d rubbed himself with still sticky with his slick.

“ Daddy’s slut.”

Izuku paused his search to meet Dabi’s eye. Whatever expression he saw there, made his blown-out pupils expand that very last millimeter they could.

“Yes, Daddy.”

The new title was too much for the alpha to take. He slammed back into that cunt and pistoned in and out as he plunged his fangs back into the barely-clotted mating mark on his omega’s neck.

Izuku didn’t have the air left to scream as the older man wrenched another brain-liquifying orgasm from him. The fact he still was able to keep going, keep cumming after squirting his brains out was a testament to his strength. Dabi truly could not have chosen a better omega. He was going to breed him over and over, keep him stuffed full of cum and pups until some other hero finally blasted his brains out. It might even be Endeavor himself, the Daddy kink originator himself back to put down the dog he couldn’t kill the first time. It certainly would provide perfect motivation for their pups to take down the false idol.

But if he died, he wouldn’t be able to keep knotting his omega, and that he would not let happen. Throwing himself entirely into his revenge plot had been so much easier before he’d gone and fallen in love with his mate, but this moment, looking his little mate dead in the eye as he creamed himself on his alpha’s cock, mouth wrapped around that beautiful call, he couldn’t help but feel this was better.

He wanted Endeavor to see him alive and well, happy with his mate worshipping him and know how completely the hero had failed. He wanted all of Japan to watch All Might’s successor bounce himself on a villain’s cock, begging for his Daddy to breed him. He wanted the world to know Midoriya Izuku was his.  

When the croon had come, Shigi had been trying to give him shit about the sheer amount of photos and videos he’d sent, whining about how he didn’t want to see this much of an omega he couldn’t push down and mount himself. He hadn’t cared, the others could gripe all they wanted, that was half the fun of showing off your omega’s nudes anyway. Showing everyone what they could only drool over while you feasted. 

Dabi had been grabbing onigiri by the fistful to shove into his omega’s heat basket when he’d heard the call from upstairs, trying to arrange it like a lovesick teenager making a flower arrangement. The sound shot straight to his dick. His omega was in heat, in their nest, ready and wanting for him.

The food basket was now a jumble in the corner from when he’d burst into the room and scattered everything that stood between him and that cunt. His omega on his back, hands pulling his slick-coated pussy lips apart for Dabi to dive right in and fuck. The sight was burned into his mind. He wished he could paint just so he could recreate that image on canvas and hang it over their nest.

Even with just photos they could make bank, really fund the league with his mate’s pretty cunt.

He could fuck him on camera, mark him again and again in front of thousands so no one could deny he sired their pups and no one else, no one able to step in and steal away what belonged to him. Everyone else would get to see how beautiful his omega was. How fucking satisfied. How thoroughly well bred by his alpha.

And it certainly would help with their mission of attracting attention.

Having his own videos of big green eyes spilling over while freckled cheeks bulge with cock, excess alpha cum running in rivulets down his bruised and bitten throat, small omega fingers lathering themselves in semen to work as lube to pump his own hole as he was being used would definitely keep his morale up on longer missions. There were so many possibilities.

After the heat, he’d set it up. For now, Izuku’s orgasm face was his and his alone.

“You’re so damn wet around me, baby boy. So wet and cummy for Daddy’s cock,” the boy’s sobbing reminder that just the word ‘cum’ from his alpha would set him off had Dabi soaring with pride. “And here you were trying to say something about how you’re not a slut, but look at you. You’re just a hole made to cum, taking every excuse to. You cum when Daddy commands, you cum when I fuck you, you cum on all Daddy’s things – don’t think I’d overlooked your slick lining my desk and chair and even my damn doorknob – Daddy’s slutty pussyboy even cums when his cunny is spanked. The more savagely I smack this clit of yours the harder you cum baby. You’ll cum no matter what I do because it’s what your omega cunt was made to do.”

“I was– I was made to – ahn! C-cum – unnh– for Daddy.”

“Did you just cum from saying it yourself?”

“N-no, I cameee eeahhh-ha-anh from Daddy’s cock!” It was a piss poor attempt at a lie and the older man would not allow his omega to think he could get away with it.

“Like hell, confess, omega.”

“I came, I came frommmm mmph the com-mand! My pussy cums– unh– every time Daddy says or I say! I keep cum- uh ming and I can-an’t st-hop!”

Izuku was so wet around him with slick and cum frothing against his cock as he plowed in. The combined stretch of Dabi’s knot and Izuku’s entire fist had his alpha cock fucking in and out with delicious speed. The little omega was helplessly folded in half, hands scrabbling in sheets, eyes crossed in pleasure, and thighs quivering under his burning hands. Dabi had effectively turned UA’s golden boy into a sex doll that came on command. 

“I’m gonna fuck you pregnant baby, going to breed you here and now and keep you stuffed full of my cum and cock. You’re going to carry my litters like this womb of yours was fucking made to do. Do you hear me omega? You were born to carry my seed, to be pupped by me. Your boy pussy knows it’s true,” he pulled out and it felt like he was tearing his own heart in half. “Say it, omega.”

“Yes! Yes! Alpha please!” Izuku writhed and whined as best he could under him with his knees crushing into his chest. Dabi was impressed he had enough air to keep begging.  

“Please what, omega?”

“Pup me! Fuck a baby into my boy pussy! I need it! I need to be bred, my pussy needs your knot so badly, Daddy, please! ”

Dabi slapped his hand down on his cunt as hard as he could, and before Izuku even had a chance to fully register the pain, slammed his knot in and came, breeding his little mate once again.

It was only once it was over did he realize he had cum. The act itself was too much, he felt like he was falling, terminal velocity only a moment away as he fell face first towards the spinning ceiling. He was falling, the world around him rushing along with his blood. Izuku scrambled, desperately clutching at anything his hands could grab ahold of. He was falling falling falling, something needed to hold him down, hold him back.

There, soft black spikes were already threaded between his fingers. He didn’t have the chance to question when he’d buried his hands in someone’s hair, or even to realize that’s what he was gripping so tightly, he was too busy trying to survive the next moment. All he could do was clamp down and hope his grip would be enough to keep him grounded when he flew. He clenched his fingers, only to find that increased the falling feeling. He was holding himself and yet the wooden planks above him swirled together with his vision in the extended moment of suspended time before his pussy pulsed with the delicious first beat of his orgasm. 

He wasn’t falling upwards, gravity hadn’t reversed, his back had simply arched so hard he’d sat himself fully up with the sheer strength of this orgasm. He flailed helplessly against the torrent, tugging hard on the black hair he’d tangled his hands in. He looked towards his hands, not down, he wasn’t oriented in space enough to understand directions yet, and into blue eyes gone electric with want. Fangs sent shudders down his spine as they traced dangerously along his pussy lips before his alpha latched meanly back onto his tormented clit.

He came over and over in great pulses that overwhelmed his senses each time. His hearing went muffled as if his brain had been turned to cotton and then back into soup repeatedly as his sight fuzzed in and out. Were his eyes crossing? Were they just rolling up into his head? The omega couldn’t process it, nothing but the shocking lights and pressures that lanced up and down his body as his alpha sucked and rolled his poor, overworked clit with his tongue.

Izuku fell back into the sheets, falling the right way this time, but his head still spun too much to feel gravity was working the right way. Dabi’s tongue didn’t let up even as the waves came fewer and farther between. No, instead he lifted Izuku’s hips from the bed to lavishing his pussy with sucks and nips and flicks of a burning hot tongue.

“Daddy, please! It’s too much! I’ve– I’ve– I’ve– AHHNG! DADDY WAIT, PLEASE! Oh my god I can’t I can’t not again–” he babbled and thrashed as hard as he could, but to no avail. His legs were weak and his body betrayed him with the fever of his heat, not that he truly wanted it to stop. Something about his alpha pushing him, dominating him so thoroughly that he could do nothing but comply. So satisfying for his omega instincts. He really had the best, the strongest alpha. 

He’d never had a hope of keeping track of how many times he’d come, but he wasn’t even sure now how many hours, how many days he’d been here folded in half, bent over the desk, pinned to the wall, twisted and rammed and plowed and ravaged beyond thought.

Dabi gave his clit another tear-jerkingly hard suck before pulling off with a pop and grinning down at him from between his raised thighs.

“Can’t what, baby boy? What can’t you do? Because if I know this pussy,” he planted a sweet kiss on his clit, “the way I think I do, I’ll bet that you can.”

“You– you know I can’t say it!”

“Can’t say what, omega?” He laughed, pleased with himself and happy to his core as Izuku whimpered and tried to hide his blushing face behind his hands. It didn’t seem to matter how many times he or his alpha said the command, it never failed to embarrass him with its lewdness. “Say the word, my little heroling, if I have to command it out of you, you know you will have to be punished.”

Izuku sniffled miserably while his omega preened, twitchinging with every breath his sadistic alpha blew over his sore cunt. Nothing was better than when his Daddy punished him. The sting of his spankings made the fireworks of his orgasms spark all the brighter.

“C-cum,” the orgasm that overtook him at the word, the tug of the original mating command in his core sent the now too-familiar spasms through his cunt and up through his entire body along his nerves. If he had been flying earlier, he was floating now. So overstimulated, the soft breath ghosting over his clit was too much, too good, too electric, he couldn’t help but jolt. Dabi laughed, the vibrations rocked through his thighs where they were splayed over strong, scarred shoulders and caused one of his leering fangs to brush the tender nub. Izuku didn’t quite cum again, but it was a near thing, the sharp sensation sending his hands scrabbling up to his alpha’s cheeks to try and hold his face back from more accidental brushes. It was the wrong move. Dabi nuzzled sweetly into his hands before brute-forcing his way past them to his slick cunt and feasting rapaciously. His body was made of sparks barely held together and his cruel cruel alpha kept forcing him through more.

“ Cum harder .” His eyes rolled back into his head, his body trembled uncontrollably as his body lit up again. Aftershocks rocketed through him, bouncing off his bones like steel balls as Dabi easily slid three fingers into his aching hole, pulling it even farther open to gaze at the cum-coated inside. “Oh my sweet boy, you’ve done so well for me. This pussy has opened up beautifully, the perfect hole for my cock.”

Even with how strung out he felt, the praise from his mate washed over him like a cool bath. He couldn’t help but smile. Alpha thought he was a good hole! Being so good for alpha! To his delight, Dabi smiled lovingly back down at him, electric blue eyes going soft and heavy-lidded with affection. Izuku had spent so long, longer than he could recall in this heat haze, his body fevered and ravenous even while exhausted beyond anything he’d ever experienced before, but the warmth that flowed through him was of a different sort. Emotional and delicious, filling his belly, sloshy with cum, with contentment.

“Daddy trained his omega well,” Izuku bashfully avoided Dabi’s intense stare, knowing the older man would take him by the chin and force him to meet his eye. Commanding, domineering, absolutely sexy. He wasn’t let down.

His alpha lowered his hips back down to the nest, viscous strings of cum and slick stretching and snapping between them at the movement, before the broad, strong form prowled up to cage him in. A large fire-scarred hand slid up his torso, trailing over his chest, to collar the expanse of his bruised and bloodied throat, long fingers digging into the soft hollows behind the juts of his jawbone.

“Let’s put you to the test then, mate of mine. I’m going to mount and take you, oversensitive as you are now, as ferociously as I want. You’re going to scream at the overstimulation. You’re going to beg me to stop, but I won’t. I won’t even if you cum yourself unconscious again. I’m going to pound this hole,” burning fingers thrust into him with violent foreshadowing, “relentlessly untill my pussyboy squirts himself stupid on my cock. I will pound you ruthlessly until this cunt, that has cum countlessly, cumes so hard you squirt what’s left of your slutty brains out getting bred with my pups. Then and only then, when you’re bound and completely broken on my knot will we pause. Just give me one more flood baby boy, and then you can have a rest. Okay?”

With the hand choking him, pinning him to the nest Izuku couldn’t nod his accent, and he was turned on too viscerally for words. He could only croon for his alpha.
