Dabi knows his heat is coming in plenty of time. He's already asked Hawks if he can stay at the Heroes apartment, and gotten the shocked yes from Hawks.
To Keigo having someplace to nest while in heat for a week was something outside Heroes and Villains. A basic need that Keigo is surprised Dabi felt the need to ask for, as if Hawks would deny Dabi a safe nesting place. It's still difficult to believe, Keigo telling him these things Dabi can't quite believe. A few days ago Dabi started nesting. Omega suppressants wearing off for the first time in years. Keigo offered to stay in a hotel while Dabi used his Apartment.
It doesn't make sense to Dabi. They're already fucking, Dabi's more attached than he ever expected to get, with anyone let alone a Alpha and Hero. He's nesting in the goddamn number 2 Heroes apartment. Dabi doesn't want Hawks to leave him alone or he would have stayed with the League. Although past memories of heats aren't good he doesn't want the Alpha to leave during the one he's choosing to spend with him. The first one in years Dabi has gone through. The misery and distress in his family home, to the mess he became while homeless. Dabi went through one heat while on the street, never again. Even if he hadn't found Giran, or a reliable supply of suppressants, he would have done whatever it took to avoid that again.
"Dabi? I really just, this has to be difficult for enough for you. I don't want to make it worse just because you don't have anywhere else." Hawks face is flushed as he stands outside the closet.
The lack of suppressants have left Dabi feeling unfocused, overly vulnerable, and Dabi can't stop the whined distress from escaping his throat. He covers his mouth best he can to muffle the pathetic cry. He flaps his hand at Keigo to ignore it, Hawks can do what he wants. Because he's still not sure what he wants. If trusting Hawks during his heat won't come back to bite him in the ass later. Dabi wants Keigo, but he's scared at the same time.
"Hey, None of that Dabi. Just tell me. Did you want me to leave something here? More stuff from the league?" Hawks questions softly as he steps closer to the Omega. Carefully trying to tiptoe around what is making Dabi feel distressed.
Nests aren't supposed to be in a closet. That much even Hawks knows. He doesn't know much else, just that Omegas make them when they feel safe. Dabi, his omega hasn't felt safe in years. Possibly ever, Keigo doesn't know how to help him. Most of the time Hawks has known him, Dabi has been on suppressants. This heat is to take a break from them, before Dabi ends up going into heat in the middle of a battle or worse. With how long it's been since Dabi had a heat Dabi's body temperature could shoot too high too fast, his heart could fail under the stress.
So when Dabi had asked if he could spend a heat here, Keigo hadn't gotten his hope's up too high that Dabi wanted to spend it with him. Dabi was just looking for somewhere safe when he didn't have any other options like any other Omega would. One without a criminal record. With how Dabi was leaning towards him and the Omega's distress, Keigo should ask Dabi what was going on before he left.
"C'mon babe, look at me and just tell me. Can't help if I don't know." He stepped closer to the edge of the nest and then he was being pulled into it. He went willingly, surprised, but willingly.
"I want you to leave you with me you dumb fuck." Dabi spat out as he curled around Hawks and laid half on top of him. He wanted him, he really really did and it scared the living shit out of him. Giving himself away with shakes and whines even as Dabi burrowed into his Alpha. Safe, Dabi knew he was safe with Keigo. Until he wouldn't be. That was also a possibility Dabi didn't want to think about. Keigo wouldn't, Keigo wouldn't do that to him. Being with Keigo was nothing like being on his knees. Nothing like the bloody memories of Dabi's only heat on the street, still healing and half delirious in pain. Keigo wasn't anything like a old john or a sugar daddy either. He was just Keigo.
"Dabi. Your shaking." He stated bluntly. Dabi grit his teeth against another whine escaping. Dabi's scent glands were damaged to hell and back but what little scent he had probably reeked of distress. He wanted to be under Keigo, in heat and in a nest for once. Have it all and just have it feel good for once. Have Keigo every moment Dabi wanted, just for a week, to come out of Heat tired and sore and happy. Satisfied in the way a cat always seemed to be.
"Is this..." Keigo tried to figure out how to word the bone chilling expectations Dabi had of Keigo the first time the Villain wound up in Hawks apartment. Dabi curling up beside him as he tried to get paperwork done on the couch. Then Dabi had begged Hawks to just get 'it' over with so he could at least go to bed. How Dabi had thought the basic supply of food or shelter had been something he owed Hawks for. Dabi hadn't been in a situation where Dabi could afford to negotiate much or say no to the help.
"Is this, like when you first stayed here? And, you thought you owed me? Even though you weren't okay with it, you tried to fake like you were?" Hawks hates bringing up their past. He'd been stupid, hadn't considered about how Dabi might interrupt an arm across his shoulders or a casual scenting.
"No. I just, - " How does Dabi tell his Alpha that he knows Hawks won't hurt him, but that he's scared anyways, while still wanting to have sex? Heat sex none the less, where Dabi's never truly been mentally present for.
"I'm nervous. Haven't ... I haven't done it, like this before. I just, I want to try it with you and get." Dabi bit his lip, squeezed his eyes shut.
"I just want, what everybody else got to experience for once." Dabi admitted with a hoarse whisper. Just once. He wanted to be able to feel what everyone else got to feel during their cycle. Wanted it with Keigo, Wanted to not be so fucking scared.
"Okay, was just making sure." Hawks rubbed one Dabi's back, kissed the top of his head. Letting out a rumble to try and help sooth the Omega resting on him. Eventually Dabi did relax enough to join with his own stuttered purr, a sound so quiet and sputtering that Keigo had been shocked it came from Dabi the first time he heard it.
"I don't want you to leave. But if it's too much or you want us to wait-" Dabi was cut off by a soft kiss from his alpha.
"If I wasn't comfortable with you I would have left when you started nesting. Why is it in here by the way? You know you can-" Hawks cut himself off as he noticed the embarrassed look on Dabi's face and how Dabi was facing away from him.
"Its smaller than the rest of your place. Quiet." He mumbled out, embarrassed it wasn't on the bed or on a couch like Shigaraki or other Omega's did.
"Fine by me, just curious." He pulled Dabi back onto his arms with soft kisses. Dabi could also see the only entry and exit point from his nest in here. Keigo noticed, but let the issue lay. Dabi's purr started again as Hawks left little love bites on his healthy skin. Only way to get past anxiety this time was through it. Dabi couldn't wait to have something good like Keigo during his Heat.
Dabi's Heat hit a few days later. He's wakes up too hot and wanting Keigo's knot in him.
"Kei?" Dabi whines hoping Keigo has kept his promise to stay. Hawks has spent the past few days pampering the Omega. Dabi still feels anxious about this next part. He's also so turned on right now, loose and slick around his entrance. Dabi usually likes taking Hawks knot but the Omega hasn't even touched himself and he wants his Alpha inside him. Wants to feel the stretch and the pressure as it fills him.
"Dabi?" Keigo's eyes widen as the faint scent of Heat hits him as he enters his closet.
"Oh hot stuff, it's here isn't it?" He questions and kneels next to the nest, patiently waiting for Dabi's permission to enter it as his omega starts trembling. Small waves of scent flow off of him. Heat and Fear mixed with want.
"I. don't-, Keigo I'm leaking." Dabi let out with a embarrassed squeak as he buried himself into the nest. Dabi's cock bobs against the blankets underneath him and he lets out a high pitched whine.
"I -I don' t- t know what to do and just -, I'm scared." Dabi grit out with a small cry as he curled into a ball. Keigo swallowed hard and reminded himself that Dabi felt safe here, with him. It's why Dabi asked to use Hawks apartment and why he called Keigo in now.
"It's okay babe. what do you need me to do? do you want me to just stay besides you? to watch, or talk to you? tell you where to touch? If you want me to go, you can change your mind Dabi." Keigo sits as close to the nest as he can glancing at Dabi's hiding form. There's no movement except for his hand, balling up a section of the nest and releasing it.
"Are you overwhelmed?" Hawks questions softly as he places his hands on the edge of the nest, where Dabi can see them. Dabi cries out with a scared whimper as he stares at Keigo. It's obvious that he wants to invite Keigo in, that Dabi's asking his alpha to help.
Keigo's eyes soften as he clasps his hand tight to the nest so he doesn't reach to comfort Dabi. it would only harm more that it would help.
"Verbal response love, I know your struggling but I need a verbal okay to help you." Keigo's voice is as soothing as he can make it while he rumbles a purr.
Dabi blushes bright red but gives a tiny nod, relaxing minutely.
"Can,canyouwatchandtellmewhattodo" Dabi wheezes out all in one breath, blush spreading down under his low cut shirt.
"Such a good Omega for me." He immediately praised Dabi and gave a sharp grin when Dabi's hips bucked sharply. Dabi was weak to praise in general but most Omega's tended to get extremely turned on by being praised. Not all, but most.
"Take off your clothes for me Dabi, let's get a look at you. my pretty Omega." Keigo purred out while Dabi stripped himself with shaky hands. It forces him to unball, Keigo checks the visible staples for signs of strain or bleeding. Dabi waits anxiously for Keigo's next instruction's. His scars are not even a thought currently, all that occupies his mind is the want for Keigo. Dabi shifts when he feels Keigo's eyes on him, gasping a little as Dabi looks at Hawks gold eyes, pupils blown wide with want for Dabi.
The Omega lifts his hands, unsure where to touch first but his dick is twitching under all Hawks gaze. Dabi doesn't know weather he wants to get off quick or put on a show for Keigo or reach back and play with his achingly empty entrance.
"Kei" he whines out. he's tempted to roll over onto his side but then he wouldn't be able to see Keigo as well.
"Go ahead and touch yourself Dabi, put 2 of your fingers in, touch your cock. It's okay if you come, it happens just go slow." Keigo's eyes are bright and he bites his lip as Dabi obeys him again but Keigo's hands stay firmly locked on the edge of the nest. He's not coming in until Dabi asks him too.
Dabi tries to tease his entrance, wanting to tease Keigo but the moment he touches his sensitive rim he groans, shoving his fingers as deep as he can, arching his back with a moan. The stretch is barely felt, no pain, not like any of his other heats just pleasure. He starts moving them immediately, whining and gasping at how much more sensitive his hole is, every nerve working double time. His other hand trembles before Dabi grabs his twitching, leaking dick. Keening and distracted by how hot he feels, he hears a wheeze turn into a cough and glances up to see Keigo's hands white knuckling the edge of the nest and a look of pride paired with a genuine smile on his Alpha's face. that's what does it, seeing Keigo so proud of him and smiling at him like Dabi is worth something. Like Dabi's precious, has Dabi Cumming with a shout as his eyes lock with Keigo's. Dabi's hole squeezes around his fingers as slick squirts out of him with a lewd moan. Keigo points out where he put the towel when he grimaces at the mess and starts looking around for someplace to wipe his hands off at least.
"you moved it last night babe, its to your left and part of the edge now." Hawks guides with a small tease in his voice. Dabi snorts, boneless from the mind blowing orgasm as he slumps in the nest. He's already ramping up for another one, he can feel it and its expected for Dabi's heat to be intense after the on suppressants. Dabi rolls onto his back and tiredly hums before letting out a deep breath, he's never heard the noise himself. At the base Shigaraki always moved his nest and locked himself away during his heat. He didn't even know if it was true that Omega's could do it, or if Dabi's fucked over vocal cords and lack of Omega qualities had taken it away. Dabi tried a soft croon anyways, calling his Alpha into his nest without having to ask, his eyes pop open with delight when a low soft noise leaves his mouth. Dabi laughs in shock before repeating he croon.
Keigo trips as he stands up, mouth open in awe as Dabi lidded his eyes and crooned at him again. he stripped as he stepped in the nest and crawled until he was over Dabi and able to silence the beckoning pleas with kisses.
"Have you been practice-" Hawks gasps when they part for air. Moaning as Dabi props his leg up for Keigo's hard on to grind against.
"Fuck, good. Your doing so well. I'm so proud of you" Keigo bent his head down kissing Dabi's neck. The scent glands were mostly useless there and the scarring prevented hickey's but Dabi still appreciated it. Keigo loved to bite on his way down to the more sensitive skin on Dabi's chest.
"I just- was too anxious before but Keigo!" Dabi crooned again, reveling in the feeling and groaned as he felt the shiver roll through Keigo at the sound. His own dick was hard again and his entrance was clenching around nothing on nothing.
Keigo aligned himself and his Omega started shaking again. The thought of being stuck on Keigo's knot during a heat was as exciting as it was terrifying. Dabi knew it would be more intense, more pleasurable, but if he changed his mind, there was also less of a chance that Keigo would be able to pull out. or that Keigo would be able to stop with how wet Dabi was. Dabi squeezed his thighs together and Keigo paused, rolling over on his side so he wouldn't be blocking the doorway. Dabi stopped him with a hand on his shoulder before he settled.
"I do like this. You do make me feel safe and theirs something about having your weight on top of me that's right." Dabi clung to Keigo and pulled him back , burying his face in Hawks shoulder. He couldn't bring himself to stop shaking but Keigo rolled their hips together, grinding their cocks in a smooth slide against each other until it lessened. Listening to Hawks groan in his ear and feeling him shiver as he rocked back against Dabi gently.
"please." Dabi whined through a gasp as his dick kicked against Hawks.
"please what baby? you wanna get off again like this?" Keigo stroked the side of Dabi's cheek down to his neck, where the damaged scent gland was. Dabi keened highly and bucked his hips up harder.
"please, Keigo. Please knot me. I want it." Dabi's entrance was already giving tiny pulses in anticipation, milking the cock he desperately wanted in himself already. Keigo reached down and taking his cock he teased Dabi's soaking wet entrance, circling it before pressing the head in. Dabi tried sinking back onto Keigo's cock, trying to stuff himself with the thick length faster. Keigo pulled away, letting Dabi's walls try to keep his dick deep in his Omega, before pushing his cock back in to the hilt, Dabi's thighs twitching. Dabi was close to another orgasm already, the cock in him felt like it belonged there, his hole was practically dripping slick from how turned on he was and he could feel the band of Hawks knot. Not large enough to get stuck yet but enough to tease that it was there. Dabi's nails dug into Keigo's shoulders above his wings as Dabi's back arched sharply, Cumming again as Keigo's dick lodged his prostate, pressing right into the bundle of nerves and staying there for a moment. Keigo swore as Dabi's hole tried to milk him of his own orgasm.
"Fuck Keigo, Alpha move." Dabi locked his ankles behind Keigo as tears from overstimulation ran down his cheeks. "It feels good"
"Dabi, so good sweetheart. perfect Omega." Keigo spoke in Dabi's ear and nuzzled at his hair as Hawks pulled himself out to slowly sink back in. driving Dabi and himself wild as his knot swelled with each pass.
"Please. knot, want your knot." Dabi let himself fall fully back into the nest, exhausted. The Omega could barely think. His dick was even tired and fill more than half way.
"Feels so good like this." Dabi kissed Keigo again. Moaning every time Keigo pushed back in and ground into his prostate.
"Can I knot you?" Keigo checked as he rocked them together and reached his hand down to start stroking Dabi's dick. Dabi threw his head back letting out a wail as he shoved his hips back into Hawks again. He crooned at his Alpha, nodding and Keigo started moving faster. his knot swelling as Dabi crooned for him in between pleasure filled moans. Keigo snapped his hips harder as the knot started getting stuck outside Dabi's rim. "so proud of you baby, doing so well."
Dabi tilted his head for Keigo to bite on his scent glands, a bond invitation if Dabi was capable and Keigo started teasing him as he popped his knot in past Dabi's rim one last time and was unable to pull it out. Shallowly thrusting as Dabi tensed, trembling on the edge of another orgasm. Keigo's knot stopped swelling too and warm cum filled Dabi, Hawks biting down on the offered gland as he came. Dabi's mouth open with a soundless screech at the new sensation of being "marked" in heat and he came between them as Keigo stroked him through it. Keigo groaned as his dick released another spurt of cum into Dabi and was rewarded with the sweet scent of arousal increasing as Dabi started purring.
"Kei,Kei listen." he nudged Keigo, exhausted and excited as he pointed to his throat. He purred again, no hitching broken cracked unbalanced purr. just smooth happy omega. His eyes watered as he basked in Keigo's arms in a nest he built and spent a heat in. This bit of normalcy had been worth struggling to.
"Holy shit babe, my dicks magic." Keigo laughed as Dabi smacked him and joined in, snickering. "Are you enjoying your heat so far Dabi?"
"It's everything I wanted to experience and more. Thank you Keigo, for giving me this back." he tucked himself as close to his alpha as he could, purring again as he felt more cum soot into him enough for his stomach to start looking filled instead of empty, before yawning and closing his eyes. "I love you."
