Ace Omegaverse
Warnings: DabiHawks attempt to navigate their relationship and what they want from each other. Assumptions are made and conversations that Dabi would rather avoid have to be had. Hawks is a version of Ace, they talk regarding intimacy and heats, how Keigo deals with those vs how Dabi is used to dealing with them.Ā
Past Sexual assault and rape while Dabi was in a previous abusive relationship are touched on.
This is not meant to represent the entire ace community or anyone in it. It is a story idea. If you do not feel represented properly by this story your welcome to give this one a tip, and request something that would rep YOU better.
Itās always inconvenient to lose a base. They are more than meeting places, thatās why they keep getting discovered. If the League had enough time to set up a warehouse where they could meet, and a seperate one where they could live, it might work out better. Shigaraki was refusing to let them split up though, eyes maniac as he scratched his neck bloody and insisted he keep his pack close.
It led them to situations like now, Dabi approaching his heat right on time and with them still trying to find some place to rest. Shigaraki doesn't stop him when he peels off from the group like he did any other time. They both know where heās going. Shigarakiās heats are too erratic to keep track of, striking suddenly, but he actually does a decent job of keeping track of the rest of theirs. He considers it part of being the pack leader, Dabi had dragged out of him during one argument over knowing where Dabi was at every moment. Apparently it drove him nuts that something could happen to a League member if they went into heat or rut and out in the open.Ā
Dabiās headed to Hawks. The Hero heād been dancing around a relationship with anyways. The recruit Dabi knew wasnāt an actual recruit. Dabi broke into the apartment enough that doing it in the rain that was pouring down wasnāt even that much of an added challenge. He picked up the feather he knew would alert Hawks he was there as he stepped inside. He set it on a table as he stripped and headed for the shower. Birdie would be home whenever he felt like it, Dabi at least wanted a shower first before he got there.
He knew Hawks, he reminded himself as he stepped into the hot water, washing his hair with Hawksā shampoo. The scent relaxed him further. Visiting Keigoās apartment was always nice, but maybe Keigo wouldnāt even come home before his heat ended. Keigo had just offered Dabi his apartment the last time he showed up smelling of post heat. Probably due to Dabi being a little more willing to light feathers on fire than normal.
Dabi stepped out of the shower feeling drained of energy, a sign his heat was settling in. He paused at the empty hallway bedroom door, considering if it was for him to use. The door was unlocked and a stack of thick comforters with blankets at the end of it. It was wide open as he paused in the doorway. Hawks still wasnāt home. He could come home at any time to find Dabi in his apartment. If he didnāt want Dabi unsupervised in his apartment he should get better locks on his damn doors. The hair on the back of his neck raised as he stepped inside, he forced his shoulders down but it felt too much like invading a room he was not supposed to be in.
Fuyumi had hated him stepping into her room; heād gotten in trouble for that often enough with the nanny. His stomach turned as he kept his ears tuned for any sound at all. There were worse consequences now than when he was a child, sneaking into his siblings room out of curiosity. Even with the type of house Touya had grown up in.
He swallowed hard as he turned and walked out of the spare room. The tempting idea of curling up by himself, placing the bedding into a half hearted nest and closing the door had been overshadowed by his unease. A mental image of Hawks dragging him out of it bringing a shiver down his tense spine. Dabi shuffled into Hawksā room instead. It smelled better there anyways. Stealing a pair of Hawksā sweats he found while snooping around, he crawled into Hawks bed, eyes drooping as he struggled to stay awake. If Hawks came back to his apartment he wanted to be aware of it.
He lost the fight eventually, after several times trying to wake himself back up. He was warm, clean, and the room smelled like an Alpha while he was about to enter heat. It was a losing battle that Dabi unwillingly gave in to. The door opening woke him up and he struggled to lift his heavy eyelids. He knows he should wake up. He gets himself prepared and ready to talk about boundaries, Sako had told it was important to establish them right away. The hand gently carding through his hair did not help.
āWhy are you in my room, hot stuff? You could have taken the blanket into the spare one.ā Keigo nudged him over and Dabiās eyes finally fully snapped open.Ā
He couldnāt just let himself drift off like that in the Heroās home. No matter how much his own instincts and heat were telling him the Alpha was safe, he knew better. Wanted to lay the hard lines and the gruesome consequences until he couldnāt enforce them anymore. His neck was burnt to hell and back, the scent gland beneath damaged and still, Alphas went for it. Heād been pressed against too many alleys nosing for that scent of safety and Alpha.
He liked Hawks, even, it wasnāt like it would be difficult to just let the heat take over. The Alpha was already kneeling on bed beside him, encroaching into his space. Dabi crawled out of the blanket and yawned, ignoring Hawksā eyes softening at him.
āDo you need any help with your heat?ā Hawks wouldnāt meet his eyes as Dabi removed his borrowed sweatshirt. Warm and soft as it was, his staples tore away from his skin too easily to let Hawks take it off later, better to just do it now.
āNo biting my scars, even for a mating mark,.ā he muttered as he swung himself over Hawks hips leaning down and stealing a kiss from the hero.
Hawks let out a soft noise of surprise as Dabi moved his attention downwards. He wasnāt even truly horny yet, just interested with his stomach doing strange swoops at the sight of Hawks. Alphas tended to relax his instincts and give a false sense of safety anyways. With Hawks it may even be real, Dabi didnāt know and didnāt want to find out how patient he could be, letting the haze of heat start fogging his mind over with itās insistence that he nuzzle into Keigoās neck. Mouth at the sensitive skin where his shoulder and neck met, right on his scent gland.
Keigo didnāt move underneath him. What was more surprising to him was that his scent wasnāt affecting the Hero from what he could tell. Most Alphas Dabi had met had one out of two reactions to him. Either they found his scent disgusting after whatever the scarring had done to them, or they didnāt care and took advantage of his damaged nerve endings. There was no arousal burning in his nostrils, Keigo wasnāt kicking him out or throwing him off of him either. He just laid there stiffly beneath him, maybe surprised Dabi was actually here. He could have offered his apartment as a joke. An empty gesture Hawks didnāt expect to be taken up on.
Not his problem if the stupid Hero had decided to offer him a safe space to spend his heat for the first time since the Leagueās base got raided and not expected him to take him up on it. This was actually not a bad way to spend one all things considered. The nagging thought that Keigo had hoped for more than Dabiās bony ass draping himself across Hawks lap still wouldnāt let him relax. His back was cold and the texture of Hawks flight suit was annoying him. One way to get him out of that.
Dabi gave a sharper nip to Keigoās scent gland and started pulling off the others fluffy aviator jacket.
āDabi, wait.ā He wrapped his wrists around Dabi's, seeming to flounder for words as Dabi stared at him dully. Keigo looked distinctly uncomfortable and a coil of unease slunk deeper into the arousal his heat was giving him. If it was a weird kink of some sort it wouldnāt make sense to tell him now. Unless he was just giving Dabi the illusion of choice. It was always the Heroes that were into the weird crap and never told him ahead of time. Dabiās blood went cold as Keigo continued to stutter uncomfortably at him and avoided looking directly at Dabi. Fine, Dabi knew he wasnāt exactly a model like the Alpha underneath him sometimes was, but Keigo never had problems meeting his eyes or looking at the Villainsā battered body any other time.
āNo biting the scars, including a mating mark. Only rule, Hawks.ā He grit his teeth and jerked his hands away from Hawks, diving for the Hero's belt and ripping it off. Boundaries, set them in stone and donāt let the Hero change them, Sako had advised him. The arousal was getting worse and part of Dabi wanted to let Hawks do whatever got them both off. Piecing his skin together or hiding the bloody slow healing marks from the League wasnāt worth it yet.Ā
āItās not my only rule. Get off me, Dabi.ā He growled as he āhelpedā Dabi, firmly grabbing him by his hips and setting Dabi beside Keigo on the bed again. The effortless way he manhandled Dabi had the Omega swallowing thickly. It did interesting things to his dick at the same time he could see Keigo throwing him out with very little effort which was not arousing.
āYou are not kicking me out like this,ā he snarled at Hawks, uncaring how stupid he must have looked in his desperation. āIf you werenāt intersested in fucking me you shouldnāt have given me the option of staying here.ā
āWhatever joke you wanted to play on me is now on both of us, I took you up on it so youāve got to deal with me,ā Dabi hissed, shivering and wrapped the comforter he had discarded earlier around himself. One of his staples pulled extra tight with the tension and Dabi grimaced.
āThis is why I wanted to talk to you,ā Hawks snapped at Dabi before taking in the way he was gripping the bed and furrowing into Keigoās comforter. Like Dabi could physically hold onto the mattress and stop the Alpha Hero from removing Dabi from Hawksā own bedroom. āI didnāt invite you to spend your next heat here to fuck you.ā
āIām sure.ā Dabi sneered at him. āThatās why you offered āhelpā, Iāve woken up pressed into a wall or mattress too many times. Tell a better lie Hawks, you're getting nowhere by waiting until Iām already in heat to talk about whatever you want from me.ā
Hawks face contorted and he finally turned around to refix his belt. The silence was deafening to Dabi, only the low growling coming from himself filing it. Breathing in an Alphaās scent, Hawksā scent from the blanket barely put a stop to it. He shouldnāt have called the other out on his lies. It had never gone well for his mother when she got sick of Enji saying heād do better and contradicted him.
āDabi, I offered to āhelpā and asked if you needed any heat products, because Iām not interested in fucking you.ā He sat down on the bed again and leaned back against the headboard. āIām not really interested in anyone like that, so if you need, I can get you some Omega products for heat relief but I donāt want to help you like that.ā
Silence greeted the room for several minutes as Dabi wrapped his head around what Hawks was telling him. It wouldnāt bother him, he didnāt think at least. His heats did make him want something in him, someone to fuck him, but that was rare and outside of heats he hadnāt thought about it.
āWeāve been flirting for weeks.ā A flash of heat pulsed through Dabi and he laid down. Pressing his thighs together against the building arousal.Ā
āBe honest about what you need as well, Dabi. I donāt trust Hawks to ask you if you donāt tell him.ā Kuroguri had quietly advised as he sent Dabi through a swirling portal.
āI, Hawā Keigo. I donāt like not knowing whatās going to be done to me. I can handle most kinks, I donāt care once the heat gets going. I canāt keep bites clean enough to avoid infection. Just tell me whatever thing you donāt trust a regular corner Omega to not stain your reputation with.ā Dabi glared out from where he was enfolded into the blanket at Hawks. His dick strained against his borrowed sweats and he moved a tiny bit closer to the Hero. He just wanted to be able to smell his scent again, maybe lay down on him and get off later.Ā
āI, Dabi, it's not you, the press. Can we get you through your heat first? Then I can tell you all about how Iām on the Ace spectrum. You're not just some corner Omega, not convenient and I do like you, just later, okay?ā Hawks ran a hand through his hair and opened up his arms.Ā
A trap, clearly a trap and Dabi scooted further into it anyways. Pillowing his head against Hawks bicep and breathing in the addicting sense of safety. Hawks ran his hands through his hair again and Dabi slumped into the touch. Was he desperate for something more to happen and alleviate some of the heat? Yes, but it was secondary at the moment to the gentle touch and scent he was foolishly buying.
āYou like to be told what Iām going to do when you're in heat. Given, whatā what you just implied, I think thatās a necessity at the very least. Iām not going to do anything sexual to you, but I donāt mind if you have to get off or want some toys to help you through it.āĀ
āYou said nothing sexual. What does that leave?ā Dabi bit his lip. He wanted to trust Keigo, he just didnāt know how to make himself fully believe the Alpha. Past experiences had taught him better,Ā every Hero every Alpha was kind until they suddenly werenāt. There had been enough favors and deals made before Girian and the League. Even if he smelled good and was letting Dabi take over his bed.Ā
āThis, cuddling and letting you scent me. Pretty much just being here for you in other ways.ā Keigo spoke softly and ran his fingers through the Villain's soft black hair.
There wasnāt a response Dabi could come up with to that. So he waited for the heat to completely take over. Like it had every other time in his life, it never happened. He just relaxed into the Alpha next to him, fresh citrus and mint filling his nose. Keigo eventually moved him closer, so he was pressed shoulder to hip against the Hero and also relaxed. Scrolling through social media on his phone.
When he couldnāt stand it anymore Dabi just, gave his body what it wanted. Small noises occasionally escaping him. He wasnāt out of control, hadnāt fought to stay focused as long as he could. Keigo asked him if he was alright when he really started burning up, and came back with a mostly frozen bottle of water.Ā
āThanks, for taking care of me.ā The words werenāt as hard to say now. Droopy eyed and comfortable in Keigoās bed.
āItās what anyone should have done, though I wouldnāt say no to a cuddle ever.ā Keigo placed a kiss on Dabiās forehead. Hesitantly, like he wasnāt sure if he was welcome to.Ā
In the following days Keigo wasnāt always there but Dabi didnāt care. The room still smelled like him when he wasnāt there and it was comforting enough. When Keigo was in his room he didnāt seem to care what Dabi was or wasnāt doing. True to his word, the Alpha mostly left him alone or let him take naps up against him. It was possibly the fastest heat Dabi had ever gone through, he didnāt have a pounding migraine or nausea when he sat up several days after he had taken over Keigoās bed.
There was the sound of him on the phone in another room so Dabi rolled his neck as he checked himself over. No torn staples and the only aches he felt were common for him. The blue eyed Omega grimaced as he stood and made a beeline for Keigoās shower.Ā
Keigo was waiting for him when he got out.Ā
āAre you feeling alright now, hot stuff?āĀ
āWhat gave it away? Showering without you nudging me for the first time in days?ā Dabi strutted up to his⦠whatever they were. Keigo was his, and he liked him enough to want to keep him. Thatās all that mattered to him.
āYeah, thereās your usual charm.ā Keigo flashed him a grin as he looked Dabi over.
āSo, since you're not checking me out when you do that. What are you doing?ā Dabi flopped onto the couch next to the man heād spent days in a bed with. While in heat. Keigo had stayed true to his word, never touching him sexually.Ā
āWho said I wasnāt?ā Keigo smiled at him, teasing just a little.
āPretty bird, Iām no model and I know we agreed to talk about your special umbrella when I was done being stupid horny and sappy,ā Dabi sneered as he spoke. Keigo glared at him but he shrugged. Maybe if the bird wanted him to be serious he shouldnāt string him along like he had.Ā
āJust because Iām Ace doesnāt mean that I donāt find you attractive, Dabi,ā he bit out.
āSo you find me attractive but didnāt take the chance when I offered up anything on the table?ā The Villain tilted his head with a slow smirk and a gleam in his eye.
āDabi, you didnāt even know what was on the table,ā Keigo calmly pointed out through his teeth. The Villain knew just how to dig under his masks, try as he had, Keigo didnāt think he could do it back. Hard to dig into a bruise when Dabi was nothing but open wounds, physical and Keigo was beginning to suspect otherwise. Some people that life hurt, got back up angry with no soft spots left.
āHave you heard of the Ace spectrum? Or are you assuming things about me again. Like that I would kick you out or take advantage of you?ā Dabiās face didnāt so much as twitch an eyelid. He was back to being wrapped up, unwilling to show Keigo much of anything.
āYou said weād talk about it but so far all I see is making excuses for, thatās the thing thatās getting me tripped up. For what? Weāve been flirting for weeks, gave me a little smooch while I was down and that was it. What gives, Keigo?ā
āI like you, I want to do things like kiss you. Take you out to dinner and listen to you when you're not being a fucking bastard on purpose. I didnāt know youād decide my room was so much better than the one I set up and left unlocked for you. Not like I actually expected you to warn me youād be over,ā he snapped at him and Dabi nudged his leg with his foot until he looked back at him.
āKiss me, but not fuck me?ā Dabi turned his hand in a go on gesture.
āKiss you, court you, you insufferable ass but no. No sex. Itās just, not something Iām interested in. Never really have been. I havenāt been leading you on, I just didnāt expect you to climb up on me in my bed like that.ā Keigo fluttered his wings and Dabi grabbed the end of one with a warm grip.
āWhen were you originally going to tell me then? Since my biology was inconvenient for you,ā Dabi drawled and let his head hang back to stare at the ceiling. The scent gland on his neck was swollen and irritated. Keigo sighed and sent a feather to find a jar of crap for it.
āPresumably when we got to that point. Some point after you stopped spooking everytime I moved in a way you didnāt expect. At the very least until after you stopped tracking every feather attached to me.ā Keigo watched Dabiās fingers tap out a rhythm as he thought. The Omega was thinking about it, tilting his head up to avoid his eyes and look like he wasnāt. The finger tapping down turned lips and biting the inside of his cheek all betrayed him anyways.
āI canāt. Not flinch. Or stop watching your hundreds of telepathic knives. Just like the, when I assumed you wanted sex from me. Iām working on it. Talking to some people. Itās the best people like me are going to get.ā Keigo opened up his returned jar and stood up, walking behind the couch. Dabi was still tracking him across the room, of course Dabi was and knowing what little Dabi had told Keigo, that wasnāt something that was going to stop. He held the jar out for Dabi to take himself.Ā
Instead Dabi drew a breath in through his nose, deep and slow, and turned to expose his irritated gland and neck to Keigo.Ā
āCourt me?ā Dabi closed his eyes and crossed his arm to hide the slight shaking of his hands. Closing his eyes as Keigo got a better look at the damaged skin around the irritated gland. Almost hidden by how it was placed was a faint scared biting mark. Keigo made sure not to touch it as he dabbed the clear thick creme on the irritated gland. No biting or mate marks Dabi had stressed.
Dabi was asking for more than how Keigo was going to court him. He was asking if he still would. Dabiās eyes flicked open when there wasnāt a response right away, only to lock onto Keigoās steely gold ones. Lips close enough that if he turned his head right they would touch. The good stomach squirming appeared and while he hesitated Keigo did not. Swooping in for several chaste kisses.
āIf you can get me that meeting with Shigaraki so I can finally get his blessing.ā Keigo pulled back.Ā
āYou're a spy,ā Dabi countered. Although at this point, it wouldnāt matter. The word 'court' spun around in his head, making it hard to think straight.
āI want to meet your best friend, your pack leader. Not the leader of the League of Villains.ā Keigo sat back down beside Dabi and wasnāt surprised when Dabi flopped himself into his lap.
āDabi, before you agree, understand that my life is very public outside of you. You're going to hear a lot about parties I wonāt remember enough to separate and who I supposedly went home with.ā A hand found its way to his and he took it. The press had wrecked most relationships. Partners thinking some person he didnāt remember enough to refute was getting some part of him they werenāt.
āLet them. Iāve spent three days in your bed, with you able to do whatever you wanted. I said you could, and you chose nothing. Only a idiot would believe you fucked someone else on a drunk whim after that. Besides, you're Ace, donāt want to fuck anyone.ā
