Chapter Text

“Omi, don’t worry, I’ll take care of it,” Atsumu said, lighting a candle and putting it on the bedside. Kiyoomi tried to ignore the tinge of panic to the Alpha’s voice, which did nothing to calm his stress levels.

Kiyoomi was too busy writhing on the bed, which seemed empty for some reason. After the wave of pain passed he found his hands moving on autopilot, arranging the bedding and blankets into a rough circle, getting all the decorative pillows from where he’d stashed them in the closet. It was only after he’d dumped both their suitcases into the middle of the soft ring that he realized what he was doing.

He burst into tears. He couldn’t stop himself, couldn’t help himself either, as he threw the toiletries and belts and shoes to the ground, keeping all the clothes, covering the ring of the pillows and blankets with their soft fabric, burying his nose into Atsumu’s shirts and finding nothing, since he’d been wearing patches the whole time they’d been there. There was nothing, nothing. Kiyoomi was tempted to grab Atsumu’s shoes. They at least had something. But even though his Omega was powerful, it was no match for Kiyoomi’s revulsion.

The lights flickered back on. Kiyoomi heard a distant curse, and then they turned back off again, the candle the only thing flickering in the room. Kiyoomi’s fear spiked and he declared his nest good enough. He burrowed into the center of it and shivered as the storm raged outside, rattling the glass windows in their frames. He was sure the snow and ice were cold, but he was hot, so hot, and so achy and empty. He felt his tears coming down his face, and he was so frustrated, with himself, for not checking his calendar and getting a prescription for suppressants before the trip, for not recognizing the signs of his pre-heat, for covering his glands and making it so no one else could smell him and warn him. Most of all, he was frustrated by the fact that he was an Omega, and that he had to go through any of this at all, that he’d been cursed by his gender from the moment he was born and there was nothing he could do about it. No matter how much he liked to fuck Betas, or even Atsumu, he’d never be an Alpha. He was doomed to be the weaker sex from the moment of his birth, and no amount of roleplay or respect or refusal to be bred would stop that from being true. His tears were angry, and depressed, but then a wave of heat washed over him, and he didn’t have time for thoughts, because all he wanted was Alpha, and Alpha inside him.

He moaned and writhed and then the lights came on, stronger this time. A moment later, he heard Atsumu climbing the stairs. The idea of Atsumu seeing him this way made him want to sob even harder.

Atsumu whispered when he came into the room. “Omi, didja want t’sleep?”

“Too bright,” Kiyoomi replied, and it was an embarrassingly broken sob. Atsumu clicked off the lights he’d just struggled to get back on.

“I can sleep in one of the other rooms, if y’want,” he said, coming to the edge of the mess Kiyoomi had made. “Y’r nest is real pretty, baby.”

Kiyoomi didn’t want to mewl at the words. The sound came out before he could stop it. He ran his fingers up and down his chest, which was wet with sweat, and when had he taken his clothes off?

“Alpha,” Kiyoomi moaned, and Atsumu chuckled, trying to play it off, even as Kiyoomi could see his eyes raking over his naked body, gleaming with desire in the golden light of the candle.

“I know y’don’t want me,” Atsumu said. “Not like this.”

“Help me,” Kiyoomi whispered. “Need you.”

“Oh, Omi,” Atsumu said, peeling off his shirt. “I’ll always help ya, any way I can.”  He lowered his head in respect. “Can I come in?”

Kiyoomi felt the wave of heat recede. Felt himself in control of his body again. He could say no.

“Yes.”

Atsumu crawled into the nest carefully, before turning back to where he’d crumpled the edge of it with his entrance. He fluffed the wall back up, replacing a pillow he’d knocked over. Kiyoomi watched him, pulling a scattered shirt over himself, to cover his nakedness. He’d never wanted Atsumu to see him like this. Even when they’d fucked, Kiyoomi had been the one in charge, Atsumu was the one begging, vulnerable, brought to tears. Kiyoomi hated being the weak one.

Atsumu reached out his arms, inviting Kiyoomi inside. Giving him the choice to accept him, or the opportunity to reject him. Kiyoomi wanted to say “no thank you,” or to at least wait a minute, to hesitate.

But there was no hesitation as he dove into his Alpha’s strong arms, felt them encircle him. Kiyoomi sighed as their naked skin touched, and without thinking, he arranged himself into Atsumu’s lap and leaned his head against his chest as if they were two puzzle pieces that belonged together.

Atsumu ran one of his hands through Kiyoomi’s hair, and let the other trace up and down his clammy back, comforting him. It wasn’t enough.

“Omi?”

“Yeah?”

“I know it’s against the rules, but I think it would help, if I scented ya.”

Kiyoomi squirmed against Atsumu’s embrace. That would be another admission. Another thing that would help his Omega, which he didn’t even want to acknowledge existed. He let out a frustrated whine, even as he felt another wave of heat overtaking him.

“M’not gonna force it on ya,” Atsumu said quietly. “Just think it would help.”

Kiyoomi started trembling, as he fought his secondary gender with every bit of self-control he had. “Fine,” he snarled. “Do it.”

Atsumu stopped his comforting touch to rip the patch off his right side, just as Kiyoomi’s eyes rolled back into his head, and his body was seized by the fire.

In his heat state, all he could do was ache, and whine, and cry, as strong arms laid him on his back, and wiped sweat from his brow. “Alpha, Alpha,” Kiyoomi sobbed, and Atsumu laid down next to him.

Kiyoomi inhaled, to moan, or to scream with the pain. The noise died in his throat instead, as he remembered.

He was ten years old, in the back yard, outside his family’s house. The Sakusas had been in Arizona then, developing the watersheds for all the new development in the Phoenix suburbs. Miles and miles of houses that all looked the same. They lived in one of the model homes.

He’d been left to his own devices, their nanny inside enjoying the air conditioning. This was nothing new. He was used to being alone, used to entertaining himself. Today, he was outside on the back patio in the shade, watching a lizard scurry across the rocks that enclosed a palm tree and a lime tree doing their best to survive the triple digit summer. The sun had been bright earlier, but it was beginning to get dark, even though it was mid-afternoon.

Kiyoomi looked up and saw the storm, long before he smelled it, long before he felt it. The wind kicked up around the yard, and the lizard scurried away. Kiyoomi stayed, and the black cloud kept coming, so fast he could watch its progress. He could see the faint paintbrush smears of grey toward the desert, where rain was already falling in a deluge.

The hairs on his arms stood straight up as the lightning flashed, as the hot brick of the earth sizzled with the first approaching drops, as the ground opened itself willingly to the flood. It was crisp and thick, and hot and sticky. Then the water came down, life-giving, refreshing, and Kiyoomi could hear it, could hear the water beyond the pitter patter of the rain and the booming of the thunder. It was a melody he found himself humming, even though he wasn’t making any sounds.

He walked out into the postage-stamp sized yard, felt the sharp blades of the drought-resistant grass as it pressed into the soft surface of his bare feet. He held out his hand, and he felt the vibration, coming not just from the rain. Coming from inside himself, echoing, reverberating, two whales serenading each other in the depths of the ocean.

T he rain around him stopped. An invisible shield surrounded him, and the drops, as they hovered in the air, gleamed with the light of the rest of the storm as it fell all around them, their spheres showing Kiyoomi’s face back to him, distorted and upside-down in the reflection. Lightning flashed, and Kiyoomi was frozen in time, smelling the grateful scent of the rain-soaked grass, the piquant citrus of the lime tree as it was nourished, the mossy scent of the earth as it became mud.

And above it all, the crackling ozone, a final lightning bolt brighter than any other, that seemed to go on forever, illuminating the wet globes in flickering fluorescence, as Kiyoomi Sakusa discovered that yes, he could talk to the water too, just like his mother, and grandmother before him.

“Atsumuuuuuu,” Kiyoomi slurred, his mouth beyond his control, every muscle dipped in honey, unable to be dragged, even through the insubstantial air.

“Here for ya,” Atsumu whispered, and Kiyoomi opened his mouth to breathe, it hurt to breathe, why did it hurt so bad? He clenched every muscle as the pain overwhelmed him, as he panted through the ache and the fire.

And then the wave broke, and Kiyoomi was washed up on the shore, surviving shipwreck. His eyes cleared, and he was able to see, past the red haze of his pain. He blinked as he came back to himself, and realized his mouth was pressed against Atsumu’s neck, right over his scent gland, as if he’d tried to eat the man alive.

“Y’back with me?” Atsumu said, rolling Kiyoomi off of him.

“How long have you known?” Kiyoomi rasped, coughing to clear his throat.

“That we’re fated mates?” Atsumu said. “The first time I smelled ya without y’r patches on.” He took the opportunity to peel Kiyoomi’s patches, off, to nose at Kiyoomi’s neck, as his own scent permeated the nest.

“The plane?”

“Yeah,” Atsumu laughed. “I was sittin’ there next t’ya, in the fancy leather chair, thinkin’ I’d never been in first class before, and probably never would be again, when all of a sudden m’twelve years old, at my grandfather’s house.”

“Tell me,” Kiyoomi whispered, closing his eyes as if he’d see the memory too.

“I’d run away,” Atsumu murmured. “Don’t worry, it wasn’t m’first rodeo. Happened all the time. Me and ‘Samu would get inta a fight, and Grandpa’d take his side, and I’d scream and yell and take off runnin’. They’d knew I’d come back when I was hungry, so they let me go.” His fingers were soft where they ran through Kiyoomi’s hair, before tracing the side of his face, a thumb brushing his lower lip, a pinky running along his jaw.

“I’d end up down by the lake, nowhere else t’go. I never went in the water alone. I was upset, but I wasn’t dumb. I’d nearly drowned with supervision, I’d definitely drown alone. Usually the solitude was good for me. The sounds of the waves, the wind in the bushes, hell, even the buzzin’ of the mosquitoes. It was soothin’. Usually. This time, it was different. I started thinkin’.”

“Did it hurt?” Kiyoomi asked with a faint smile, unable to stop his snark, even in the throes of his pain. Atsumu laughed, before kissing him on the eyebrow, twice.

“Glad y’re back,” he whispered.

“Not for long,” Kiyoomi said, his eyelids clenching as he felt pinpricks of sweat emerging from his hairline. “Keep going, I want to hear your story.”

“Okay, Omi, whatever y’want,” Atsumu said, running his nose along Kiyoomi’s jawline, kissing him over his swollen glands, as he took a deep inhale.

“I started thinkin’ about why no one ever ran after me. How even though I’d had my brother from the moment I was born, I was always so alone. I just felt like, and this is gonna sound stupid and overdramatic,” he sighed, and Kiyoomi laughed again, even as he felt the heat rising from his center, a low burn that simmered beneath his skin. “I know, I know. I wondered when I’d find someone who would be there for me. Not outta obligation, but, yeah. Outta love. And that’s when the storm started.”

Kiyoomi found himself ramrod straight, even as the heat attempted to melt his muscles into a puddle.

“I saw it comin’,” Atsumu continued, rubbing Kiyoomi’s body as if he’d help the tension dissipate. “But I was too angry t’go home. Even though I could see the lightnin’ and knew a lakeside was probably the worst place I could be. M’not like you, y’know?” he murmured. “I don’t come from generations of elementals. I’m the first in m’family. Think we got a flame thrower on my mom’s side, somewhere, that’s it.”

Kiyoomi wanted to nod, wanted to agree, but he was too overcome, by the fire licking through his body, and by the effort of holding it back so he could listen.

“I’m out there, and the rain’s fallin’, and at first all I can smell is the salty brackishness of the water. But the ground, the ground’s gettin’ this sweet smell, as the water hits it. And that doesn’t make any sense t’me, because I’d never thoughta the rain as sweet, it’d always been musky, or earthy. It’s almost like roses, but like, a little bit spicy.”

“Jasmine,” Kiyoomi whispered through his gritted teeth, opening his eyes to look at Atsumu’s face, even as tears ran down his cheeks for some reason, even though he didn’t feel frustrated, or angry, or sad. Even though the pain wasn’t worth crying over.

“That’s when the whole world went white,” Atsumu said. “Because I was struck by lightnin’. I could feel it in me, like, like—”

“Like a song only you knew the words to.”

“Yes,” Atsumu hissed, his eyes sparking with the analogy. “That’s perfect. I could never figure out howta say it, it’s like, y’feel it in ya, like a vibration, but there’s a meaning to it—” he broke off at the description.

“It went inta me, and I felt it, and I could control it, and it was like, like, a parta me that was missin’ was found, and it didn’t hurt, it felt so good, so much power and I could control it, and I was laughin’ so hard, and I threw my hands up t’the sky, and the power, the power went outta me and shot inta the clouds.” He smiled at the memory, and even though Kiyoomi’s pain was intense, he smiled at it too, because Atsumu’s joy was so obvious, he was glowing.

“And after that, I looked around and the whole of Pleasant Harbor RV Resort was watchin’ me.”

Lake Pleasant. Arizona. Kiyoomi wanted to be surprised. He wasn’t. He lacked the mental capacity for surprise. He clenched his eyes shut.

“And when I smelled ya, outside of work for the first time, not wearin’ y’r patches, and I smelled the flowers, and the ground, and the storm, I knew Omi. I knew y’were mine.”

Kiyoomi couldn’t help whining at that. He let go, allowing the wave of his heat to crash over him, feeling Atsumu’s mouth against his neck, smelling Atsumu’s scent wash over him, a comforting presence, his hands running through Kiyoomi’s hair, his hands on Kiyoomi’s body, his skin against Kiyoomi’s skin. It wasn’t enough.

“Need you, Al-Atsumu,” Kiyoomi begged, his mind and body on fire, a fire he couldn’t put out if he tried.

“Not like this,” Atsumu said, his own voice a plea. Kiyoomi’s tears were in earnest. Why wasn’t his Alpha giving him what he wanted, no, what he needed? Did Alpha want him to hurt so bad? Was he bad?

“No, baby, no,” Atsumu answered, and Kiyoomi howled. He felt his wet face being pressed into Atsumu’s neck, and the scent was stronger now, and mingling with his own, and he was so wet and hot it was as if the storm from his memories had returned.

The pain didn’t leave, but it lessened, and Kiyoomi fell unconscious.

He came to, and Atsumu was still holding him.

“Omi?” he heard, as he disentangled himself from Atsumu’s limbs. “Baby?”

“It’s passed,” Kiyoomi croaked. “For now.”

“You need water, and you should eat something,” Atsumu said, pulling away as if he would leave.

Kiyoomi held him even tighter. “Atsumu.”

Atsumu stopped at the command in Kiyoomi’s voice. “Yeah?”

“I need you.”

“I toldja, Omi, m’not takin’ ya like this.”

“You’re not taking anything,” Kiyoomi insisted, his voice strong with authority even though the syllables were cracking under the strain of his emotions. “I need you.”

“That’s just the heat talkin’,” Atsumu insisted. “Y’re gonna wake up in the mornin’ and hate me for doin’ it.” his voice began to shake. “I can’t live with y’hatin’ me, Omi.”

“I won’t,” Kiyoomi insisted. “I’m lucid right now, and Atsumu, you already—you know I don’t hate you, right?”

Atsumu’s lip was wobbling, as if he’d start crying, and the idea of a big bad Alpha being brought to tears was so funny Kiyoomi almost wanted to laugh, but he knew it would break Atsumu’s heart if he did.

So he didn’t.

“I toldja I liked ya,” Atsumu said. “Two days ago. An’ y’said ya ‘didn’t dislike me.’ That’s not exactly a ringin’ endorsement.”

If someone had told Kiyoomi a week ago, hell, even a day ago, that an Alpha existed who wouldn’t help an Omega through their heat without a heartfelt confession, he would have laughed in their face.

Now he knew this Alpha existed, and his name was Atsumu Miya. He was a hell of an arcer, and an amazing rival. He was kind, and good with kids, and nice to everyone, even his evil old grandmother. He was an excellent snowboarder and made a mean chocolate chip cookie. He picked out thoughtful gifts, even for people he’d known less than a week. He’d taught Kiyoomi about tradition, about family, about the true meaning of Christmas. He was Kiyoomi’s fated mate, and even then, he didn’t want to take advantage of him. And Kiyoomi loved him for all of those things, and more.

Kiyoomi loved him.

“I love you, Atsumu,” he whispered, admitting it not just to himself, but to the man fate had determined to be his best match.

“Oh, Omi,” Atsumu sighed, and then he was kissing him, his lips firm against Kiyoomi’s own, his tongue darting into his mouth, to taste, to consume.

Kiyoomi mewled, as he felt the faint lick of flame inside him, a fire he knew would grow, incinerate them both. He pressed their bodies together, his hands flying to Atsumu’s waist to undress him completely.

“No, no,” Atsumu said, pulling away, and grabbing Kiyoomi by the wrists, his touch firm but gentle. “I gotta get some things first. I’ll be right back, I promise.”

He sprang out of the nest before Kiyoomi could even protest. Not that it stopped him. Once Atsumu was gone, the nest was so empty. Kiyoomi felt so alone. Alone again, just like every other heat, he thought in despair, and he smelled the floral notes of his scent turn bitter, moldering under the sadness of his loneliness.

“Drink,” Atsumu said, bringing him to a sitting position, when did he even come back, and putting a bottle to his lips.

Kiyoomi took a gulp and choked. “What is this?” he gasped.

“Drink,” Atsumu said, and Kiyoomi drank it down, only realizing when it was halfway gone that Atsumu had commanded him. He shivered at the realization.

He did more than shiver. He slicked too, and the heat gathered in his core, dripping down his inner thighs.

“I put salt and honey in a bottle of water since there’s no Gatorade downstairs,” Atsumu said. “Y’r gonna need electrolytes after sweatin’ so much. I don’t wanna hear about how it tastes bad,” he laughed. “M’doin’ the best I can.”

Kiyoomi finished the bottle, and fell back on the bed, panting. Atsumu took it from his limp hand and Kiyoomi heard a distant clatter as it was thrown from the nest.

He opened heavy lids and found Atsumu’s face hovering above his own, his eyes glowing, his fangs dripping from where they were protruding from the corners of his mouth. “Atsumu,” he sighed, wiling his hands to reach for his Alpha. They were so heavy he could only raise them a few inches before they fell back onto the mattress, on either side of his head.

Atsumu’s powerful fingers threaded through his, pinning his wrists where they lay. Kiyoomi’s eyes shot open in terror, and Atsumu ripped his hands away.

“Omi,” Atsumu said, climbing off him, even as Kiyoomi panted. “Y’don’t want this.”

“I do, Atsumu, I do,” Kiyoomi said, reaching for him. “I’m sorry.”

“Don’t apologize,” Atsumu said, laying on his side. “It’s y’r feelin’s, and they’re valid.”

“It’s hard to…” Kiyoomi started, trying to find the words. “It’s hard to have you on me.”

“Then I won’t be,” Atsumu said. “Easy t’solve.”

“No, no,” Kiyoomi said, as the heat moved up his spine, and his breathing got quicker. “I want you, please, just, lay there?” he asked, reaching for Atsumu with a shaking hand, wanting to touch and have but afraid to let go.

“Omi,” Atsumu said, pulling him to his side, too, so they were facing each other. Neither of them on top of the other. Equals on the battlefield and in the bedroom. “I’ll do whatever y’want me t’do.”

“Touch me,” Kiyoomi said, his hand on Atsumu’s jaw, his thumb running over his lower lip. “Please, Atsu.”

He brought their faces together as his wave crested, as the heat came over him, making his toes curl and his skin prickle. He kissed Atsumu deeply, feeling his Alpha kiss him back, tasting him, drawing moans from his mouth as he nipped and sucked and growled.

Then Atsumu’s hand was wrapped around him, stroking him, and the relief Kiyoomi felt was so palpable he threw his head back to sigh, a breathy, “yes, yes,” coming from his throat, as he felt his orgasm building, already close from just Atsumu’s hand on him.

And what talented hands, as Kiyoomi felt Atsumu’s other hand against his slick entrance. “You want it here?” he asked, and Kiyoomi’s yes became more than just a breath, it was a moan as he begged Atsumu to keep going.

Atsumu’s thick finger was inside him, a hook bringing him closer to the edge of release, pulling and pushing, even as his other hand twisted around him, Atsumu’s thumb in his wet slit, Atsumu slipping a second finger inside him, working it into him, he’d never had someone like this before—

Kiyoomi’s eyes flew open as he came, hard, his dick kicking spend over his chest, dripping onto Atsumu’s fist, as Atsumu worked him through it, murmuring soft praises, his own eyes hooded and heavy as he licked his lips. Kiyoomi slicked over Atsumu’s other fingers, easing their passage as they languidly thrust in and out, opening him up further. Kiyoomi felt like he was still coming, heavy with sensation, as he melted into the mattress.

“So good for me,” Atsumu murmured, before kissing Kiyoomi, licking at his lips. He brought his hand up to his face and licked it clean. “Y’taste so good, Omi. I want some more.”

Kiyoomi’s back arched as he writhed at the praise. “Please,” he gasped.

“What d’you want?” Atsumu asked, ready and willing to serve him.

“Want you to taste me,” Kiyoomi said, and Atsumu didn’t need to be asked twice. He shimmied down the bed and dove between Kiyoomi’s legs.

Oh, Atsumu’s tongue inside him was better than just his fingers, Kiyoomi understood, as Atsumu licked from his entrance up the back of his cock, to swirl his slick and spend together in a mixture that made both of them moan. “Yes, yes.”

Atsumu’s fingers joined his tongue, now, slipping into Kiyoomi’s river, and he sobbed as Atsumu licked at his rim while rubbing against his prostate. He was going to come again, and he couldn’t help it, couldn’t stop himself from chasing the feeling, of being so fulfilled, of feeling so good. “Like that, like that,” he blabbered, as his hips bucked against Atsumu’s face and his hands scratched at the sheets.

Then Atsumu’s other hand wrapped around his cock, tugging once, twice, three times, and Kiyoomi was coming again, shooting a second line of spend across his chest, alongside the first. He screamed at the onslaught of sensations, his mind emptying of all thought as he gushed in Atsumu’s fist and around his fingers.

Unlike the other waves, his orgasms didn’t satiate him. They just made him even more feral. He’d done all he could to satisfy his inner Omega. The bitch wouldn’t be satisfied. It wanted more, more, more, a gaping maw that could never be filled.

“Atsumu,” Kiyoomi moaned. He opened his eyes, and there was Atsumu’s face, hovering over him, but not on top of him, next to him. Tears pricked Kiyoomi’s eyes at his thoughtfulness, at the concern written plain on his features, even as his mouth was covered with slick, even as his eyes blazed with lust and want.

“Did it help, baby?” Atsumu asked, and Kiyoomi felt tears run down his cheeks as he shook his head. “D’ya wanna stop?”

“Want you,” Kiyoomi said. “Inside.”

He watched Atsumu take a deep, shuddering breath.

“And y’won’t hate me for it? For doin’ it?”

“I love you, Atsumu.”

Atsumu seemed like he was near tears, too. “Omi, I love ya so much, y’know that? I love ya so much it hurts sometimes.”

“Then love me,” Kiyoomi begged. “Love me, Atsumu.”

Atsumu turned away, and Kiyoomi heard the crinkle of foil before he turned back. He looked down at Atsumu’s thick Alphan cock, and realized he was wearing a condom. Kiyoomi sobbed at the respect even as his inner Omega screamed at the betrayal.

Atsumu raised Kiyoomi’s leg, and draped it over his own hip. “Let’s try like this, okay?” he asked, and Kiyoomi nodded, feeling Atsumu pressed against him, feeling his weight, understanding that it was going inside him, where no one had ever been, where he’d never wanted anyone to go.

Then Atsumu was pressing inside, as his lips kissed Kiyoomi’s tears away, before his tongue licked into Kiyoomi’s mouth. Kiyoomi gasped as he was filled, his hips jerking forward to help Atsumu put it in further, deeper, faster. Atsumu snaked a hand down to his waist, stopping him from moving, and Kiyoomi wanted to howl, wanted to bite his tongue off in frustration. But Atsumu was big, and he felt himself stretching to accommodate him. He understood he might rip himself apart if he tried to rush.

The drag of Atsumu inside him was enough to bring his dick back to a rock-hard erection, even after coming twice already. Atsumu lifted his leg higher, and Kiyoomi had never been so thankful for his flexibility, as his knee was pressed to his chest. He felt himself slick further, his body doing its best to accept the intrusion.

“Y’okay?” Atsumu asked, and Kiyoomi gasped as he felt him keep going, even though he was sure he couldn’t take any more, how did he keep taking it?

“Yes, Atsu, yes,” Kiyoomi said, feeling their bodies against each other, realizing Atsumu was all the way inside, feeling him throb inside him, feeling his hot and heavy weight, even as Kiyoomi slicked even more, in anticipation, in excitement. Atsumu just held himself there, breathing heavily into Kiyoomi’s mouth, even as Kiyoomi wanted him to move, to fuck into him, to own him and break him and claim him. Wanted it so bad it scared him. But Atsumu was waiting. For what?

Then he felt himself relax, felt his body adjust, felt himself slick again, and Atsumu began to move, began to drag himself back out, savoring every inch, even as his tongue pressed against Kiyoomi’s lips and devoured him.

“Nh, nh, nh,” Kiyoomi moaned into the kiss, as Atsumu pushed back in, just as slowly. This, this is what I wanted, this is exactly what I wanted.

Atsumu picked up the pace, moving in and out of Kiyoomi a little faster, and it was even better. Kiyoomi gasped as he tried to ride Atsumu back. It was hard, with one leg up in the air and the other on the bed. He needed Atsumu deeper, needed to be able to take more of him.

“Please, Atsumu,” Kiyoomi said, even as Atsumu drove into him, the sounds of their wet skin obscene in the candlelight, a puddle spreading beneath where their bodies were connected, thanks to Kiyoomi’s endless arousal. “Need more.”

“Come here, Omi,” Atsumu said, grabbing him by the hip, and rolling onto his back, taking Kiyoomi with him.

Kiyoomi adjusted himself, one knee on either side of Atsumu’s hips, and oh, he was so much deeper now, fuck, Kiyoomi could feel him so much more.

“Ride me, baby,” Atsumu said, putting his hands on either side of Kiyoomi’s waist, holding onto him.

Kiyoomi rolled his hips, forward and back, bracing himself on his hands, where they were splayed on Atsumu’s chest. “Oh, fuck, Atsu,” he gasped, as he felt Atsumu’s thick cock pull out of him, and then get sucked back inside. “You feel so good, you feel so good.”

Atsumu was looking up at him in rapt wonder, as Kiyoomi continued to move his hips like a wave, crashing into Atsumu’s dick, feeling it driving deeper and deeper into him. “Y’re so beautiful, Omi,” he said, reaching up to run his hand over Kiyoomi’s face. “I wanna kiss ya so bad.”

Atsumu braced himself on his forearms, sliding upwards on the bed, so he was sitting up, and Kiyoomi put his hands on either side of Atsumu’s head, grabbing onto the headboard for support. Then he leaned forward as Atsumu leaned forward, meeting in the middle for a sloppy kiss.

“Fuck me back,” Kiyoomi moaned, and Atsumu moaned in return, before thrusting up with his hips and making Kiyoomi see stars. “Oh, fuck me, fuck me,” he sobbed, as he bounced on Atsumu’s cock, as Atsumu’s tongue was shoved down his throat, as Atsumu’s hands were on his hips, driving them down with every thrust of his dick.

Kiyoomi howled when one of the thrusts hit his prostate, dead on, and he gushed a stream of slick as Atsumu continued his steady pace. “Right there, right there,” he begged, as Atsumu fucked into him incessantly, until Kiyoomi felt like he was going to explode.

That’s when one of Atsumu’s thick hands wrapped around his cock, and that was it, Kiyoomi was screaming as he came, over and over again, his hand fisted into Atsumu’s hair, his head thrown back in a howl to the ceiling. His dick kicked ropes of clear spend across Atsumu’s chest, all over his abs.

Kiyoomi distantly realized that Atsumu was still hard, and still inside him, and his inner Omega was happy, but still hungry.

“Knot me,” he begged, bucking his hips, even as his forearms fell toward the bedframe and his head rested against the wood.

“I don’t think that’s a good idea in this position,” Atsumu said sheepishly. “Y’can barely sit up.”

Kiyoomi hit Atsumu with a weak punch.

“Let me lay down,” he said. “Can you knot me that way?”

Atsumu chuckled. “Yeah Omi, I gotchu.”

He sat up, his hands around Kiyoomi’s back, and let him fall to the side, so he was laying down. He withdrew carefully, trying not to hurt Kiyoomi where he was sensitive. Kiyoomi caught his breath as he started to fall asleep, before his Omega reminded him he had needs, with a fresh wave of cramps. Stupid fucking cunt, Kiyoomi thought. He was so exhausted there was no real fire to it.

“Roll onto your other side,” Atsumu said. Kiyoomi did, stretching his sore body out, and enjoying that he got to lay down again. “Legs up, okay?” He felt Atsumu’s strong hand lifting his knee into his chest, and Kiyoomi sighed in contentment, even though they hadn’t done anything yet.

He felt Atsumu at his entrance, and he slicked again, as if he needed to. He was surprised his body had anything left to give. He felt loose, sloppy and fucked wide open. Atsumu slipped inside, and this time there was no need to go slow. He was ready to get what he needed.

“Please, Atsumu,” Kiyoomi said, pushing his ass backwards, forcing it to swallow more of Atsumu’s cock. “Fuck me.”

Atsumu slid home, and did just that, his pace frenetic from the first thrust, as he chased his own pleasure.  “Fuck, Omi, y’just—fuck, y’re killin’ me.”

Kiyoomi moaned wantonly, as Atsumu grabbed him by his ass, yanking him toward him, his other hand twisted in his curls. “Like that, please, Alpha, fuck, like that, Atsu,” he babbled, looking down at his dick in incredulousness, as it got hard again somehow. He wrapped a shaking fist around himself, stroking his cock in the same rhythm as Atsumu’s thrusts.

“Gonna knotcha, okay baby?”

“Do more than that,” Kiyoomi’s Omega answered. “Claim me, breed me, fuck me full.”

Atsumu huffed a laugh, in place of an answer. His pace began to stutter as he fucked into Kiyoomi harder.

And Kiyoomi felt it, felt when Atsumu’s cock swelled up, when it began to catch on every other thrust instead of making its way inside. And the idea of acceptance, of embracing his Omega side, just this once, was what had Kiyoomi coming again, painting his own hand with his spend, as his ass gushed a new wave of slick that allowed Atsumu to push inside and stay there.

Even with the condom, Kiyoomi could feel Atsumu’s cock throb as it gushed out pulse after pulse of cum, sticky gobs that Kiyoomi imagined were painting him white on the inside as Atsumu filled him full of his seed. He moaned as he finished stroking his cock, as he wrung himself out, adding it to the mess of slick and spit and tears that they were soaking in. He decided not to be disgusted, and turned his head to Atsumu’s. “Kiss me,” he demanded, and Atsumu wrapped his arms around him and kissed him deeply, completely, even as he continued to fill him up. Kiyoomi had never felt so satisfied in his life. He broke the kiss to settle into his pillow with a happy sigh that came out in a soothing rhythm.

He'd never purred before in his life.

“Baby,” Atsumu said, rubbing his face into Kiyoomi’s neck. He began to croon.

Atsumu was a song, too, his vibrations matching Kiyoomi’s own. Kiyoomi felt himself shiver in contentment, at the feeling of Atsumu around him and inside him, at how he didn’t mind being an Omega, at least in this moment.

He felt post-orgasm clarity wash over him as his heat subsided, and he wiggled his toes, happy to be floating in the river of serotonin and oxytocin that was coursing through his veins. He was in love with Atsumu, and he regretted nothing.  His Alpha had treated him so right, not forcing him to present, not biting at his glands, not breeding him, or claiming him, even when Kiyoomi had begged him to. He kept purring, even as he held Atsumu’s hand, which felt wet for some reason.

He held it up in front of his face, and there, in the meat between his thumb and forefinger, was a perfect semi-circle of teeth, a deep, bloody bite mark, met by its twin on the other side.

“Atsumu?” Kiyoomi asked, interrupting his purring to turn his head in Atsumu’s direction, even though he couldn’t make eye contact, not while they were pinned so close to each other. “What happened to your hand?”

“Ah, nothing,” Atsumu said, embarrassed. He pressed a kiss into Kiyoomi’s neck, and filled him with a fresh wave of cum. Now that Kiyoomi had come back to himself, he was a little disgusted by how sticky and wet he felt. He hoped Atsumu’s knot didn’t last too long. He needed a shower, as soon as possible.

“Doesn’t look like nothing,” Kiyoomi said. He brushed Atsumu’s forearm with his lips, avoiding where he was bleeding. “Looks like a pretty deep bite.”

“Yeah, it hurts like a voltfucker,” Atsumu laughed, no longer able to keep up the deception. “Shoulda done my forearm, but my hand was closest t’y’r neck, Omi.”

Kiyoomi raised a curious hand over where his glands lay, no longer swollen and puffy. He ran his fingers over the unmarked tendon. He shivered at the idea that the bite on Atsumu’s hand could have been his neck, bleeding and torn open. He wasn’t shivering out of fear, however.

Atsumu had bitten himself, instead of marking Kiyoomi, even though he’d begged the Alpha to claim him. Kiyoomi loved him so much. “Atsumu, I—”

He gasped as Atsumu grasped him tight, filling him a third time.

“Sorry, Omi, it’s gonna be five times all n’all, and we’ll be tied up at least twenty minutes,” Atsumu apologized. “Case y’re wonderin’.”

“I was just going to tell you,” Kiyoomi continued. “I love you.”

“I love ya so much, an I’m so glad I get t’be y’r fated mate. Y’re so fuckin’ perfect f’r me. God,” Atsumu said, holding Kiyoomi tightly, “I love ya so much.” He sounded like he was crying, and Kiyoomi felt his tears as they slipped down his face to lay on Kiyoomi’s neck, even as Atsumu continued covering him with kisses and filling him with cum.

“How did you get the lights back on?” Kiyoomi asked, even though, in the end, they’d made love by candlelight.

“Y’r parents have a fancy-ass electrical generator in the garage,” Atsumu explained. “But it wasn’t charged.”

“What did you do?”

“Charged it,” Atsumu said. “Then I hadta make sure it worked, and it did, so I charged it some more.”

“You’re convenient,” Kiyoomi laughed, and the laugh was wiped off his face as Atsumu filled him one last time. He moaned at how good it felt, at how complete he was, now that he’d found his Alpha. “Can you charge my phone?”

“If you’ve got a plug, I’m your man,” Atsumu. “Glorified electrical outlet.”

But he’s the one in me, Kiyoomi thought, and laughed at his own joke.

“What’s funny?” Atsumu asked, almost as if he were upset.

“You’re the one plugging me,” Kiyoomi explained. He never wanted Atsumu to feel bad. Not like that. Not anymore, anyway.

Atsumu laughed at that, too, and Kiyoomi felt better about everything. He realized Atsumu was stroking his lower belly, where his cock was still buried inside him. Imagining me full of his pups, Kiyoomi thought. He realized he was going to disappoint Atsumu, since none of it was ever going to happen.

“I thought you wouldn’t want to be with me,” Kiyoomi said. “Since you want pups, and I don’t want to get pregnant.”

“There are other ways of havin’ a family,” Atsumu said. “If ya want one. ‘Samu and Rin are gonna adopt, and we could, too. An’ if y’don’t want a family of our own, we can always just be the best uncles in the whole world.”

Kiyoomi thought about how good Atsumu had been with the kids all week. Imagined him holding his own child, how much he would dote. He’d volunteer to stay home and raise their pup. Kiyoomi wouldn’t have to get pregnant, wouldn’t have to stop his career. Wouldn’t have to be an Omega. Could just be Kiyoomi. Could just… be.

“Can I think about it?” he asked.

“So not a definite no?” Atsumu asked in return, his voice filled with a hope he couldn’t hide.

“I don’t think so,” Kiyoomi answered honestly. “Not a definite no. You’d make a good dad.”

“So would you,” Atsumu sighed, kissing Kiyoomi behind his ear, on his jaw, his neck, his shoulder, anywhere he could reach. Kiyoomi felt a happy flutter at the fact that Atsumu hadn’t changed it to “mom” or “dam” on his behalf. They could be two dads.

A world of possibilities seemed open to him. He smiled stupidly. He looked over, and even so close, he saw Atsumu smiling back at him. His smile didn’t seem stupid, it seemed hopeful. And full of love.

Maybe Kiyoomi’s smile wasn’t so stupid after all.
