Third Person POV

It was the third day since being captured, at least, that's what Midoriya thought. He is unable to tell time since the dark room he was being locked and held in had no windows and the only light source was from under the metal door that separated him from the League.

Midoriya, disoriented, awakes to find himself incredibly sore, as usual ever since he stepped in this hell hole. He rolls his head to the side to see his arms bandaged but it was still a slight red color, his blood probably having stopped spilling but still soaked the bandages a decent amount. However, that's the moment he notices that he was still in his tattered green hero suit, of course his gear is missing though. But what made him snap out of his daze was the cold, metallic item around his neck, as he remembered it had been some sort of leather earlier.

Sitting up quickly, the greenette found himself choking back when he felt the collar pull tight around his neck. Coughing a few times, he shakily glanced back to see that not only was he wearing a collar, but a metal chain was attached to it and to the metal bedpost. Just great.

Midoriya now tried to examine his surroundings while keeping quiet, noticing that he was alone in this room. A small wave of relief washed over the green haired Omega at the fact that he could at least collect himself enough to wrap his head around what happened to him, and to try and look for a way to escape.

Pulling against the collar to see if it would budge, even if he doubted that, he suddenly feels a sharp jolt of pain hit his body and he flinched back to let the chain go slack again. Of course, a shock collar that also negated his quirk, even better in his situation! Leave it to the black market and the League of Villains to have such a cruel item that would keep someone as perfect as him here and under control.

The Omega is snapped out of his thoughts when the door unlocks and begins to open, in which he snaps his gaze to the now blinding light seeping into the dark room. He winces and shields his eyes with his hands for the moment until the light disappears and he is able to see once again. However, he wished he had never opened his eyes, because there stood Shigaraki and Dabi, grins across their faces and hunger glimmered in their eyes. Midoriya knew he wasn't safe and the little bit of relief he had earlier was shot down at the sight of the two Alphas locking the door and approaching him.

Dabi was the first to approach the boy while Shigaraki seemed occupied doing some other thing at the moment. "S-stay back," Midoriya immediately tried to shift away from the Alpha but he's harshly yanked back to his previous spot in the middle of the bed, Dabi now grabs his wrists and holds them tightly as his turquoise eyes bore into the Omega teen chained to the bed, sending an icy cold shiver down Midoriya's spine.

"You'll soon enjoy this, Omega boy. If you don't squirm, maybe we'll go easy on you," Dabi spoke in a low, husky voice that made Midoriya want to vomit. He knew what they wanted from him and though he had been trying hard to deny it and make himself believe they were just going to torture him, he couldn't do anything to stop it now.

"Back off, Daddy Issues. I called him first, so hands off my Omega," now, Shigaraki came into the picture, and the moment he referred to Midoriya as 'his' Omega, he felt his heart plummet.

Shigaraki shoved Dabi aside who just moved to sit on the edge of the bed while watching, slowly taking his shirt off before the pale blue haired male crawled on top of Midoriya, pinning him to the bed and smirking widely. The greenette tried to inch away from him but couldn't, refusing to turn his head away in fear of exposing his neck where his precious, unmarked scent glands were. The older male's red eyes also had deep hunger and desire in them while he grabbed the smaller male's wrists and began to tie them above his head.

"No! Get off! You damn villains, get the hell off of me!" Midoriya started thrashing, trying to kick the Alpha off of him but Dabi caught his left leg and with one hand on his pinned wrists, Shigaraki grabbed his right leg and forced his leg to the side, effectively placing himself between his legs and keeping them spread as he leaned forward to mash his dry lips against Midoriya's in a sloppy kiss. Midoriya's eyes widened and he tried to get free or at least get Shigaraki's lips off and away from him, so he bit down on the other's lip and that made the Alpha release his lips and wrists. The freckled teen tried to pull his hands down so he could land a punch to Shigaraki but found that his wrists were not only tied tightly to each other but to the bed frame, preventing them from moving anywhere where they could be a threat.

Shigaraki pulled back and pressed a finger to his lip, noticing that it was beginning to bleed and suddenly, a dangerous look appeared across his face. "You little shit brat," the Alpha growled deeply before he suddenly lunged forward and grabbed the side of Midoriya's head, forcing it to the side and forcing him to expose his bare neck. Deep fear rushed through Midoriya as he realized what was about to happen, and he began to thrash again in a pitiful attempt to get Shigaraki off of him but to no avail. The older Alpha possessively growled in his ear before sinking his teeth into his scent gland, marking the Rogue Omega as his.

Pain shot through Midoriya's body once again as Shigaraki marked him and for a moment, he felt his body go numb. A bit dazed, he realized that Shigaraki and Dabi were now growling at one another and beginning to argue.

"What the fuck, Handy Man? I though we'd both get to mark him, dumbass," Dabi growled in anger as he faced Shigaraki who growled back. A deep scowl on his face, the dark haired Alpha bared his teeth as a sign of anger and a display of dominance.

Shigaraki responded with his display of dominance while still in between the Omega's legs and on top of him. "Fuck off. I already told you, he's mine. I could care less if you fuck him, but don't try that bullshit."

Midoriya comes to and smells that their pheromones are flying at each other, dominant pheromones that make him lightheaded from the sheer amount that was oozing off of them. And they seem to argue and bicker for a couple of minutes until Shigaraki snaps back to his new Omega and grabs the chain attached to his collar, pulling it just enough so it wouldn't shock him but he still noticed the pull.

"Hey, Omega brat, why don't you be a good slut and go into heat for us, huh? I'd be so much easier if you did," Shigaraki sneered and Dabi watched Midoriya's reaction and expression like a hawk. Seems like they were done arguing, or more like their Alphas decided to take control for the majority of their minds and redirected it to the pinned Omega male under Shigaraki.

Then, anger blossomed inside of Midoriya at the question and he bared his small Omega fangs. "I'd rather die," he spat at Shigaraki and Dabi, his focus finally coming back while he glared hatefully between them, especially the man above him.

"So be it. Go into heat. Now."

All of a sudden, Midoriya feels the familiar wave of intense warmth overcome him and though his mind resists, his Omega had no choice but to follow Shigaraki's Alpha Command, his Alpha's Alpha Voice. His vision begins to blur a bit as the first wave starts and like all his previous heats, his body rises in temperature, his heat expels more of his sweet heat scent, and his lower region starts to become coated with slick. He feels his worst nightmares are about to come true and he was powerless to stop it.

"That's more like it~ Let's have some real fun now~" Shigaraki hummed huskily, the scent of his Omega in heat pushed his Alpha in control and the same happened with Dabi. The two who were just arguing were now side by side, on top of the poor Omega, and beginning to inhale more of his delectable heat scent as they quickly grew hard in their pants.

Quickly, the two Alphas discarded all of their clothes, tossing them and forgetting about them while Midoriya struggled to get a grip on himself. He was just barely able to remain conscious, but remained unable to do anything against them, against the two Alphas who had him in their grasps now.

"P-please, s-stop......I d-don't want this, please..." tears quickly run down his face as the two now rip away at his hero suit, until he was bare naked beneath them, his hard member and slicked entrance on full display.

Shigaraki and Dabi quickly start to lick his skin, but they latch onto his nipples and begin to suck and bite them, triggering unwanted pleasure to flow through him. The two worked swiftly in leaving visible marks on the claimed Omega's skin, moving down as well until Shigaraki lifted Midoriya's hips up until his rear was at the level where his entrance was now clearly seen.

Shigaraki immediately shoved his tongue into his entrance, splitting him open for the first time by someone other than Midoriya himself. Pleasure wafted over him enough to let a moan out, his member twitching and the tip leaking precum as Dabi continued to suck and bite on his left nipple and pinch the other with his fingers. Shigaraki hungrily lapped up his sweet tasting slick and occasionally shoved his tongue back in in an attempt to scoop out more for himself. He finally couldn't resist it any longer and he let Midoriya's hips drop down into his lap and nudged Dabi, letting him know it was time to start.

Midoriya feels even more fear hit him but like before, his body is unresponsive to his cries to move and to fight. Going silent to let his Alpha and his Alpha partner have their way with him.

Shigaraki strokes his cock a few times and groans as his eyes remained locked on the green haired Omega's twitching entrance. He licks his lips before finally giving in to his lust and presses the tip of his member against Midoriya's asshole, making him whimper and whine. And without warning or even preparation, Shigaraki jerks his hips forward, shoving his entire cock inside of Midoriya who wailed in mixed pain and pleasure, his body tensing up and he pulled against the rope restraining his hands.

Then, the pale haired Alpha started to thrust wildly even though droplets of blood slipped out past his full entrance. He gripped tightly to Midoriya's hips and clawed at his skin for grip as he slammed into him relentlessly, drunk off of pleasure now and getting even more the more he shoved his cock in and pulled out only to thrust back inside of his Omega.

Midoriya continued with his pained screams that reverberated off of the cold walls in the room, his body and the bed beginning to shake and jerk from the intensity of Shigaraki's restless thrusts. Then, Dabi pulled his head to the left and while his mouth was still open, he too shoved his dick into him, only, it was his mouth instead. He choked on his thick length and swore his eyes rolled back into his head but he couldn't be sure as his heat was beginning to worsen now that he was being mated, and mated hard too.

Soon enough, the Rogue Omega's cries and screams turned into loud moans and panting, his green gaze laced with a layer of lust despite his heat having been induced forcefully, against his will. He was sure that the rest of the League could hear him outside of the room. Midoriya could feel how big Shigaraki was whenever he'd thrust inside until all of him was in his tight entrance, and he swore the two Alphas would've remarked about it if their inner Alphas weren't in full control of them right now. Some time passes of continuous thrusting from both of the League members, one in his ass and one in his mouth, until their members began to throb and their knots started to swell.

"Gonna fuck you up so good, Omega, that you won't want any other cock other than mine's~ You're gonna be full and pregnant with pups, then we'll continue breeding you like the slut you are~" Shigaraki growled through his moaning and huffing. Then, both Alphas' thrusts became more erratic and sloppy.

"Fuck~ Take it like the good Omega slut you are!~" and finally, Shigaraki slams one last time into Midoriya, knotting him and cumming deep inside him while Dabi does the same, but his knot was too big to fit the Omega's mouth so he couldn't get the same satisfaction as Shigaraki, but it was enough for now. The green haired teen ends up climaxing as well while the Alphas' seed fills both his insides and his mouth, sliding down his throat as he's forced to swallow it all.

Midoriya feels completely miserable and violated that he feels like passing out, but he can't. He's ashamed of himself for climaxing as well, but knew it was only because of his forced heat. He thinks it's over and he's partially relieved until Shigaraki pulls out of his entrance, nearly ripping his ass apart as he screams in agony again, and starts thrusting once more. Dabi luckily withdrew earlier after cumming but was now jerking himself off, watching Shigaraki fuck Midoriya again.

—

What felt like hours go pass until Shigaraki and Dabi finally are done and spent for the time being, leaving the poor Omega used and wasted on the bed with white stains over not only the sheets, but his body too, mostly around his face and lower region. The two Alphas had taken turns in using Midoriya, fucking him raw and senseless and cumming inside of him each time so much so that more leaked out of him whenever they withdrew because he could only hold so much.

Completely exhausted, Midoriya finally feels the last bit of his heat fade for now, and he is able to at least get some sleep, hopefully to wash away all of this but he knew that was naive to think like that. He could only pray that his friends or the Pro Heroes and All Might would be able to find him before things got even worse.
