Chapter Text

Being mated to his two handsome, alpha seniors was not something Osamu foresaw in high school. Really, he thought his crushes on them would remain unrequited, and would eventually fade (not). At fifteen, Osamu fanaticized about being their omega and receiving their attention at all times. Now, at twenty-seven, he had it and more.

Just, right now, Osamu wasn’t sure that it was a good thing.

When Aran and Shinsuke had approached him towards the end of his time in university, both of them asking to date him, wanting him to be theirs, Osamu had been flabbergasted. Sure, he was still as close as ever to the two, and sure, there had been years worth of romantic and sexual tension building up for longer than Osamu would like to admit, but still! He didn’t think both of them would confess to him!

After Osamu’s mild cardiac episode and a lot of reassurance and praise from both alphas, the omega eventually agreed, but not before having a long, awkward discussion with his alpha twin.

“Hah? What the fuck’re you talkin’ about, Samu?” Atsumu shrieked, making Osamu groan into his hands.

“Can you stop bein’ so fuckin’ dramatic? I need yer advice, not yer theatrics!” Osamu complained.

Atsumu wholly ignored him, going off on his own tangent, “Aran-kun and Kita-san wanna mate ya? Both of them? What the fuck, were you a goddamn prince in yer last life? How the fuck didja get so lucky?”

Osamu glared at his twin, “What, ya wanna sleep with them?”

“Well, I wouldn’t be opposed to it,” Atsumu mumbled, making Osamu smack him upside the head, “Ow, fuck! They aren’t even yer alphas yet and yer already this possessive?”

“Shut up,” Osamu said, pretending like he wasn’t pouting, “I’m sure that Ushijima-san would love ta hear that you wanna sleep with Aran-kun and Kita-san,” he jibed, making Atsumu flail.

“Don’t rat me out, ya fuckin’ snake!” Atsumu whined, making Osamu glare again.

Osamu huffed, “Then don’t talk about sleepin’ with them! Ya already have an alpha of yer own!” he complained.

It was Atsumu’s turn to roll his eyes then, “Stop cryin’, ya big baby, ‘m kidding. Why would I need anyone else when I have the alpha of the V.League? Besides, Aran-kun and Kita-san want you, don’t they? Why’re ya hesitatin’ anyways? You’ve had a crush on them since, like. Forever,” he questioned, an eyebrow raised.

Osamu stared at his hands, “Just – ain’t it a bad idea? Aran-kun and Kita-san have been datin’ fer years. And now suddenly they want me? What if they just want me cause they want an omega to –“

Before Osamu could finish his sentence, Atsumu interrupted, “Osamu,” he said, voice so serious it stopped Osamu in his tracks, “It’s Aran-kun and Kita-san. You of all people know they aren’t like that. They’d never toy with anyone’s feelings, much less yers. Don’t you think yer just tryin’ ta talk yer way outta this?”

When the omega failed to respond, Atsumu sighed, wrapping an arm around his brother and speaking softer, “I know yer scared, Samu, but there’s no reason to be. This is Aran-kun and Kita-san we’re talkin’ about. They’ve always cared about ya. Ya don’t remember how protective they were of ya in high school, when you suddenly went into heat during practice?” Osamu groaned at the memory, flushing.

“That was humiliating,” he whined, making Atsumu cackle.

“Yeah, ya gave me a heart attack that day,” the alpha replied, earning him a shove from Osamu. He ignored it, continuing, “I was holdin’ ya close and tryin’ to bat everyone off, but Aran-kun and Kita-san refused ta leave yer side. They weren’t touchin’ ya, but they were hoverin’ so hard. And then they walked us home, as if I wasn’t an alpha who could protect you. They kept checkin’ up on ya and bringing snacks to the house – oh wow why didn’t I realize that they were inta ya back then –“

“Okay! Okay, I get it, Tsumu, stop,” Osamu groaned, face bright red. He remembered all of that; how scared he’d felt until the only scents he could breathe in were his twin’s and his favorite alphas’. He also remembered Atsumu leaving the plastic bags of all his favorite snacks by his door, grumbling that they were presents from their seniors. The sweet notes that Aran and Kita had written for him were still tucked away in a drawer at home, a precious memory to him now.

Osamu sighed, “I do really like them, Tsumu. I wanna be with them, but…ain’t it unconventional? Two alphas with one omega?”

Atsumu stared at his twin for a moment, before smacking him. Before Osamu could retaliate, Atsumu went off, “Samu, I am in an unconventional relationship. Aran-kun and Kita-san are currently in an unconventional relationship. A bunch of alphas fuckin’ each other ain’t exactly standard, if ya didn’t know,” he deadpanned, making Osamu stutter.

“I didn’t mean that there’s anything wrong with –“ Osamu stammered, making Atsumu roll his eyes fondly.

“I know, stupid. ‘M just sayin’, there’s nothing wrong with bein’ in a relationship that looks different than what we grew up seein’. As long as you and Aran-kun and Kita-san are happy, who’s to say that it’s wrong? It’s yer life, Samu. Do what ya want, and be with who ya want to, no matter how it looks,” Atsumu said gently, making Osamu finally smile.

He wrapped his arm around the blonde, “Thanks, Tsumu,” he whispered, making his twin smile back.

“Course, Samu. Always got yer back,” Atsumu replied.

That had been over five years ago now, and Osamu could confidently say that that decision had changed his life for the better. After he’d told Aran and Kita about his acceptance of their proposal, the two alphas had been overjoyed, excited to finally have Osamu the way they’d been wanting him for years now. It had made Osamu very blushy, but very happy.

A year after that, Osamu was able to make one of his dreams come true, when he opened Onigiri Miya. It was also around that time when he was officially mated by Aran and Kita, the trio so content and in love. The gold wedding bands the three shared were a constant reminder of their commitment to each other, as well as the scarred-over bite marks on all of their necks; a physical manifestation of their love and their lives together.

And now, at the age of twenty-seven, Osamu was making another dream of his, of all of theirs, come true.

“Osamu, what’s this?” Kita asked softly, holding up the box on the kitchen counter. He’d just walked into their shared home when he noticed the present, sending a questioning look to his lover.

Aran walked over to the other alpha, “Samu got us somethin’, but he refused to let me open it until you got here too. Said it’s fer the both of us, so we had to open it at the same time,” he explained, pressing a kiss to Kita’s temple.

Osamu watched his anticipation, a small smile on his face. He gestured to his alphas, “Open it then.”

Kita unwrapped the ribbon, letting it fall as he pulled the top off. Osamu knew the exact moment both alphas realized what it was, their breaths catching and their eyes bulging with disbelief.

“You… you’re –“ Aran started, stuttering as he tried to regain his words.

“You’re pregnant?” Kita finished, looking up at Osamu with hopeful, wet eyes.

Osamu felt emotions well in him, leaving him unable to speak, so he nodded his head, smiling at his two alphas. There was a moment, before –

“Oh my god, baby!” Aran shouted, running to his omega and sweeping him right off his feet, making Osamu let out a surprised laugh, “Yer pregnant! Yer havin’ our baby!”

“Aran-kun, it’s dangerous!” Osamu yelled, even as he laughed and felt his heart soar at their reaction.

He felt Aran tighten his arms around him, setting him down but letting Osamu nuzzle into his neck, “My baby. My darling. Yer pregnant,” Aran breathed, holding Osamu so close to him, clutching him like he was the most precious thing in the universe.

Osamu let out a bubbling laugh, “I’m pregnant,” he said, voice cracking as his emotions took over.

Before he knew it, Osamu felt Kita pressed up against his back, nuzzling into the back of Osamu’s neck, “Yer pregnant. Sweetheart, you’re having our baby,” Kita said, voice shaky.

The omega turned, looking at Kita who had tears welled up in his eyes. He snaked an arm around his shoulders, “I’m havin’ our baby, Shin. Aran-kun. We’re gonna have a family,” he said, smiling even as tears spilled down his cheeks.

Aran and Kita were quick to press kisses to his cheeks, making Osamu giggle, “We’re gonna have a family, all because of ya. Thank you, sweetheart. For giving us this joy,” Kita said softly, nuzzling his omega’s neck and pressing kisses there.

“Thank you fer giving us everything and more, Samu. We love ya so much,” Aran choked out, pressing a kiss to the top of Osamu’s head.

“I love you two. So, so much. Thank ya fer lettin’ me be yer mate,” he cried, basking in the attention of both of his mates.

After announcing his pregnancy to his mates and Atsumu (who had sobbed uncontrollably for so long, Ushijima had begun to grow concerned), Osamu had been on cloud nine. While he was nervous about giving birth and about the new life they’d have after having a baby, more than that, he was excited. Osamu had always dreamed of having a family, and it was finally coming true.

The only thing was, his alphas, who were already very protective of their omega, seemed to go into overdrive once they learnt that Osamu was pregnant.

Not long after finding out Osamu was pregnant did the intense doting start. Usually, Osamu made breakfast in the morning alongside Kita, while Aran slept. But now, Kita would wake up even earlier, making breakfast alone for his mates, as well as preparing bentos for both of them. At first, Osamu had thought it was a one-time deal, but after a week of it happening, realized that his mate was doing this on purpose. When he asked, Kita had just replied sweetly.

“I just want to take care of you, sweetheart. You need your rest before work, and this way you’ll be on your feet less,” he said as he pressed a kiss to his mate’s pouting lips.

Osamu had accepted it, knowing that his alpha was trying to lighten his load and take care of him. He knew that he had the two most doting alphas in the world, so Osamu prepared himself to be even more spoiled that he already was. He just didn’t know how much more they would step it up.

The next thing was that Aran had begun visiting him at Onigiri Miya during his lunch breaks. Now, this alone was no problem; Osamu loved when Aran had the time to stop by during lunch, and getting to chat and make food for his lover was a highlight of his day. The only problem was that he wasn’t coming to eat; he was coming to work.

“Aran-kun, what are ya doin’?” Osamu exclaimed, watching his mate put on an apron.

Aran just looked back at him with a sweet expression, “I’ll help ya take orders and serve, baby. Don’t worry, I got an hour before I have to go back to the gym,” he said, pressing a kiss to Osamu’s temple and scenting him.

Osamu just stared back, incredulous, as his lover went to the cash register and began taking customers, a charming smile on his face. Begrudgingly, Osamu let him stay, preparing orders while grumbling about his mate. Aran should be resting, not working during his lunch break!

After half an hour, Osamu had enough, “Aran-kun, go eat,” Osamu said sternly, pushing four onigiri towards his lover.

“Samu, I’m fine. Why don’t you go sit down instead? I’ve got this,” Aran said kindly, petting the back of his omega’s head.

As much as Osamu wanted to give into his mate’s affections, Osamu held out, “No, Aran-kun, you have ta go in a little bit and ya haven’t even eaten anything yet! Ya gotta eat or else you’ll faint durin’ practice,” he scolded, scowling when Aran only smiled.

“I’ll be fine, baby. I’ll take it to go and eat on the way back. Now, why don’t you sit down and rest while I clean up a little?” he replied, ushering Osamu into a seat at the bar quickly. Osamu wasn’t even sure how they ended up here, but suddenly he was sitting and munching on an onigiri, watching his handsome, strong, persistent mate clean his counters and tables in his own damn restaurant. What the hell was going on?

Frankly, Osamu thought his mates were being a little ridiculous with the amount of spoiling they were doing. First of all, Osamu was only a few months pregnant! He wasn’t even showing yet, and they were already treating him like he was full term! He could still wake up early and make breakfast, and he could still work during rush hour with no problem. There was no reason for his alphas to be as protective as they were being, and he was going to give them a piece of his mind!

And yet despite his conviction, Aran and Kita were able to have their way with their omega. After all, they were so sweet about it; showering Osamu with affection and adoration from the moment he woke up to the moment he went to bed. Every day when he got home, Aran would take his bag from him and help him out of his shoes, while Kita scented him and rubbed his shoulders. The two spoiled Osamu with all their attention, making the omega preen. There was just no way for him to reject their protectiveness, no matter how ridiculous Osamu thought they were being.

Oh, and if Osamu thought they were acting insane before? After they found out the news at his three-month ultrasound, they went downright feral.

“It’s twins?” Osamu all but screeched, staring at the ultrasound tech like she was growing another head out of her body.

Unaware of what was going to come, she smiled brightly, “Yes, congratulations! You’re having twins. I read in your chart that you’re also a twin, isn’t that amazing? Sometimes it just runs in the family,” she said kindly.

Meanwhile, Osamu was reeling as he looked over at his shell-shocked mates, staring at the ultrasound machine in disbelief. And there it was, their two pups on the screen, right next to each other.

“Osamu,” Aran said, voice cracking as tears fell from his eyes, “This…thank you. This is everything to us,” he mumbled, pressing kisses all along the side of his omega’s face.

“Please, print out many copies of this. We’re going to need a lot,” Kita said, voice so warm and happy, the ultrasound tech agreed readily.

“Two?” Osamu said softly, causing everyone to look at him, “I’m…I’m really having twins?”

Kita took Osamu’s hand then, pressing a soft kiss to it and looking at him affectionately, “Yes, sweetheart. You’re having twins. Is that…are you happy with that?” he asked, wondering if this was too overwhelming for their mate. They hadn’t asked before getting excited, what if Osamu didn’t want twins for some reason?

There was a moment of silence where everyone held their breath, watching Osamu with rapt attention, before a small smile made its way onto his face, “Well, I guess so. That means they’ll have their own Tsumu,” he said softly as tears fell from his eyes.

Both alphas were quickly all over him, rubbing his cheek and holding his hand while murmuring praise, the doctor just smiling at the scene. Osamu just took it all, watching the screen where his pups were being shown, smiling at them as he thought about him and Atsumu, crying all the while. Maybe this wouldn’t be so bad.

Unfortunately, that feeling of excitement did not last.

Now, objectively, Osamu knew that his mates would get even more protective once they found out he was having twins. He knew that their alpha instincts would be set to overdrive, having two pups to protect, as well as a more vulnerable pregnant mate. However, Osamu couldn’t help but feel irritated with how overboard he felt the two were going. So much so, that he was complaining to his twin about it.

“They’re just being so overbearing! I can’t even make myself a snack anymore, Tsumu! They drop whatever they’re doin’ and make it for me!” Osamu whined, kicking his feet and pouting.

Atsumu stared back, nonplussed, “Oh, the horrors. They care,” he said unsympathetically, making Osamu kick him, “Ow, fuck! God, who said being pregnant would soften you up? Yer still such a scrub,” he groaned, rubbing his shin.

“Would it kill ya to just listen ta me? I can’t even talk to them ‘bout it cause they just start sweet-talkin’ me and I fall fer it every time! I’m going crazy here!” Osamu said, a bit hysterically.

“I don’t see what the big issue is here, Samu. They wanna talk care of ya, isn’t that good? They’re excited ta be parents, especially to twins –“ he said, voice cracking at the end, making Osamu roll his eyes.

“Are you serious? Tsumu, I toldja a month ago I was havin’ twins, are ya really still cryin’ about it?”

“Shut up, Samu! Ya don’t understand!”

“Considering I’m yer twin, ‘m pretty sure I do.”

“It’s just – they’re gonna be like us!”

“God, I hope not.”

“Why you –“

“Atsumu is just emotional because this has been his dream for years now, Osamu,” Ushijima explained, startling Osamu as he’d almost forgotten the alpha was here (he was preparing dinner for them. Osamu would never understand why such an upstanding man decided to mate with his twin).

Osamu looked at the other alpha in confusion, “What do ya mean, his dream? Me getting pregnant with twins was yer dream?” he asked, turning to look at his brother who was getting suspiciously red.

Ushijima huffed a laugh, “Well, since Atsumu and I cannot have children biologically, his dream has been to be there for you when you have children. Secretly, he’s been hoping for you to have twins because he wants to raise twins himself, like the two of you were raised. He thinks it’s sweet, as do I,” he told Osamu, making him blink before turning his attention back to Atsumu.

“Why’d you gotta expose me like that, Ushiwaka?” Atsumu mumbled, face red.

“You should just be honest with your brother, Atsumu. Then he would understand why you’re on Ojiro-san and Kita-san’s side,” Ushijima said kindly, smiling at his mate.

Atsumu pouted, “Yeah, but now he knows ‘m soft fer him. That I like him.”

Ushijima blinked, before, “My love, you’re rubbing his feet as we speak. I’m sure he already knows,” he said point-blank.

The blonde squawked from where he was sitting, as if suddenly realizing his twin’s feet were pillowed in his lap and he was rubbing them. He was quick to reply, “That’s cause he has fat fuckin’ feet and ankles! I can’t let ‘im walk around with cankles, what if people think it’s me?” he shrieked.

“Hey, fuck you!” Osamu shouted, the two immediately bickering. Although, from where Ushijima was, he could see that it was half-hearted, as Atsumu was still rubbing his twin’s feet and Osamu was melting into their couch. The sight made him chuckle to himself as he stirred their soup for dinner.

“I think you gotta just tell ‘em how you feel, Samu,” Atsumu said as he scarfed down some rice, making Osamu grimace.

“Can you eat with some fuckin’ manners? How does Ushijima-san put up with ya?” Osamu complained, making Atsumu stick his tongue out at him.

Ushijima picked up a napkin and gently dabbed his mate’s face as he spoke, “Atsumu is right. If there is something bothering you about their treatment, you should tell them directly. Even if they have good intentions, it’s all for nothing if you feel smothered,” he added, looking back at Osamu seriously.

Osamu shied under Ushijima’s stare, “Yeah but I don’t wanna hurt their feelings. I know they ain’t doin’ it to upset me,” he mumbled, sticking a spoonful of soup into his mouth.

“Course they ain’t, but it doesn’t matter. If ya want them to stop babyin’ you so hard, ya gotta tell them, Samu. Or else they’ll just get worse and worse, and then you’ll snap and make ‘em cry,” Atsumu told him seriously.

“I wouldn’t make Aran-kun or Shin cry,” he said dryly, giving his twin a skeptical look.

Atsumu shrugged, “I dunno about that. Yer pretty mean, and you’ve only gotten crankier since ya got knocked up –“

“Shut yer stupid, fat –“ Osamu growled, almost lunging across the table before Ushijima stopped them.

“I think it’s almost time for dessert,” he stated, making both twins perk up considerably. Leave it to the promise of sweets to get the twins to stop fighting. Ushijima Wakatoshi was truly a miracle worker.

When Aran came to pick up his mate that night, Ushijima made pleasant conversation with him at the door while Atsumu helped his twin get his shoes on, speaking quietly, “Yer gonna be fine, scrubbie. Jus’ tell ‘em how ya feel, and they’ll adjust. Yer their precious baby, they’ll do whatever ya want, as long as you tell them that what they’re doing ain’t it,” he whispered, hugging his twin goodbye and smiling at him.

Osamu smiled back, “Thanks, Tsumu. I’ll see ya later,” he said, waving at the pair of alphas as Aran took his other hand, leading him to the car.

“How was yer twin time? Any pain?” Aran asked as he strapped Osamu in, making Osamu huff a laugh.

“Besides Tsumu bein’ a pain in my ass, it was fine. Ushijima-san bein’ there helps us not fight as much,” Osamu explained, making Aran chuckle.

He shook his head as he replied, “Thank god Atsumu married someone as responsible and upright as Ushijima. He’s the only one who can wrangle in all of Atsumu’s energy without gettin’ exhausted,” Aran joked, making Osamu giggle.

As they drove home, Osamu thought more and more about his mates and the gestures they’ve shown him since they found out he was pregnant. It wasn’t necessarily like he minded everything. He liked that they were even more cuddly with him now, and the small acts of service. It was just that they were doing an overwhelming number of acts of service, and it was starting to make him feel useless in his own pack. Osamu didn’t like that, and if he wanted to change it, Atsumu was right (something he hated admitting to); he needed to tell them.

When they parked, Aran was quick to go around the side of the car and open the door for Osamu, helping him out of the car. While Osamu’s belly wasn’t too big yet, he was still showing earlier than he thought he would, considering there were two pups in there. As Aran held his hand and brought him inside, quickly slipping off his own shoes before helping Osamu take off his, the omega couldn’t help but feel guilty for not wanting his mates to be doing all of this for him.

So, what did he do? He started crying.

“Osamu? Baby, are you okay? What’s wrong?” Aran said quickly after noticing the tears falling from the omega’s eyes.

“Aran? Osamu? What’s going on?” he heard Kita call, making a sob rip from Osamu’s throat. That seemed to startle the alphas more, their protective instincts flaring at the sight of their blubbering mate. Aran was quick to pick his omega up, carrying him to their sofa and setting him down.

Kita cupped one hand to Osamu’s cheek, while Aran cooed and rubbed his back, “Sweetheart, what’s wrong? Are ya missin’ Atsumu? Do you want to call him?” Kita asked, eyebrows furrowing when Osamu shook his head.

“What’s goin’ on, baby? Tell us, it’s okay,” Aran pleaded softly, pressing a kiss to Osamu’s hairline.

Osamu sniffled, “I just – I feel so overwhelmed –“ he started, sobs pouring out of his mouth.

Kita hummed, “Is it work that’s overwhelmin’ ya? You don’t have to go in tomorrow, sweetheart, we’ll call yer workers and take care of it,” he explained sweetly, rubbing underneath Osamu’s grey eyes.

Aran agreed quickly, “Yeah baby, we’ll take care of it. We’ll make sure ya can just rest and not worry –“

“It ain’t the shop that’s overwhelmin’ me. It’s you two,” Osamu sobbed, the guilt rushing over him as he felt both of their hands freeze, shock running through them at Osamu’s words.

“…Us? We’re making you feel overwhelmed?” Kita whispered, hand frozen on his lover’s cheek.

“It – I – please don’t be upset,” Osamu begged.

Aran jumped in then, “Osamu, just tell us what’s goin’ on. I promise, we won’t be upset with ya. We just wanna know what’s going on in that pretty little head of yers,” he promised, hand on his back slowly starting to rub again.

“Yes, Aran’s right, Osamu. We won’t get upset. Just talk to us,” Kita whispered, cradling his mate’s cheek once again. And that’s what finally caused him to break.

“It’s just – I don’t mind that ya want to do stuff fer me. Honest. I think it’s sweet, cause ya love me and our pups so much, I get it. It’s just – it’s a lot sometimes. Like, our whole routine has already changed cause the two of ya are so worried about me,” Osamu mumbled, making Kita coo at him, “Ya don’t let me help with meals anymore and ya come help at the restaurant without me askin’ and it’s nice, ‘m not mad, it’s just. I’m not useless, ya know? I’m pregnant, but I can still help around the house and work in my own restaurant. I know yer just tryin’ to be sweet, but it feels overwhelming when everythin’ is changing so fast and yer basically rendering me useless. I know eventually it’ll be hard fer me to work and that there’ll be times that I don’t wanna cook, but that’s not now. Fer now, I wanna make breakfast and dinner with my mates and I wanna make ya onigiri when ya come in on yer lunch break and chat. I don’t wantcha to do everything fer me right now. Maybe when I’m about to pop, but not right now,” Osamu explained as best as he could, even as tears still dribbled down his face.

There was a moment of pause while the alphas absorbed what Osamu had said, before Kita spoke, “So, you feel overwhelmed by the way we’re making you feel helpless?”

“Yes,” Osamu mumbled, feeling guilty.

Kita sighed, “Sweetheart, why didn’t you tell us sooner?”

“I knew you were doin’ it ta take burden off of me, so I didn’t wanna complain, but. But I just –“ Osamu stuttered.

“You didn’t wanna hurt our feelings, but you also didn’t wanna seem ungrateful,” Aran said kindly.

Osamu nodded, “Yeah, exactly. I just didn’t wantcha to think I was bein’ mean,” he explained shyly, although he was grateful that they understood his jumbled speech. The two of them always knew what he was trying to say. It was why he loved them so much.

Kita sighed fondly, “Sweetheart, we would never think that. We know that you’re going through the toughest time out of all of us, and we just wanted to help ya. But if what we’re doin’ is just stressin’ you out more, then it’s fer nothing. We didn’t mean to make you feel like you couldn’t do anythin’ anymore. We just wanted to ease any burden,” he said softly, smiling at his pregnant mate.

“I know, I know that’s what you were tryin’ to do. I just – I know lots of things in our lives are gonna change now that we’re havin’ pups, but I don’t wanna change everythin’ just yet. I – I wanna still take care of the two of ya, just like you wanna take care of me,” Osamu whispered, feeling his face flush.

Aran chuckled, “Course ya do, cause yer so sweet, baby. Okay, let’s figure out what yer boundaries are, and we’ll stick to it, okay? We still wanna help and take care of ya, but if there are things ya feel like ya want to do yerself instead, then let’s talk about it so we don’t make ya feel bad again,” he said softly, making Osamu finally smile.

Kita cooed at him, cleaning off his omega’s face while Aran wrapped his arms around Osamu, pulling him into his lap and letting him nuzzle into his neck. Osamu sighed happily at the touch, making both alpha’s laugh. Kita was quick to join them, coming to Osamu’s other side and pressing against his back, all three of them intertwined.

“Thank you, fer listenin’ to me and not gettin’ defensive,” Osamu whispered, feeling warm and safe in his lover’s arms.

“Of course, sweetheart. We’ll always listen to what you have to say,” Kita said softly, rubbing against Osamu’s mating scars.

Aran agreed, “Always, baby.”

And when Osamu felt his twins kick in his belly, he knew that they felt just as content and safe as he did at that moment.

Chapter Text

After Osamu’s conversation with his alphas, their relationship improved quite a bit, to Osamu’s glee. He felt a lot better just by telling his alphas his feelings, and that feeling only improved when he noticed the changes they made to their routine for him. Kita began waking Osamu up to cook breakfast with him instead of for him, Aran came to the restaurant during his lunch breaks to eat and chat instead of helping, and the trio cooked dinner altogether at night instead of Osamu just watching. It made Osamu feel more included in their routines, as well as helpful, which was important to him. He could see that his alphas were happier too, seeing their mate be happy as well.

His relationship with his alphas? Perfect. His relationship with his pups? He was sure these babies were trying to kill him.

At the five-month mark, Osamu started to have bouts of nausea and vomiting, much to his dismay. Certain smells and textures triggered him so badly, he would barely make it to the bathroom before he was yacking. It was to the point that Aran had thrown out his favorite cologne, and Kita had switched body washes, less he wanted Osamu to vomit in bed.

Thankfully, he didn’t have too much trouble with food. His texture issues were quickly resolved by Kita, who began bringing home fresh produce and grains from his farm and the neighboring ones.

“Once my neighbors found out my mate was pregnant, they practically forced all this stuff on me,” Kita had relayed to Osamu, who’s eyes bulged at the amount of produce on their kitchen island.

“They didn’t have ta do all of this though! It’s so much…” he trailed off, even as he felt his mouth water seeing all the yummy things in front of him. Still, he felt guilty that they’d given so much to him, just because he was pregnant.

Kita had just shaken his head fondly, “They wanted to, sweetheart. Everyone knows how important you and Aran are to me, and they wanna help me take care of ya and our precious little babies,” he explained softly, wrapping his arms around Osamu and pressing a kiss to his pout. That got a smile out of the omega, making Kita mirror it.

“Okay,” he conceded, before excitement filled him, “What should we make with it?” Osamu asked, making the farmer laugh.

The fresh foods had helped tremendously with his texture issues, to all of their relief. Osamu was able to still eat a lot of what he wanted, and was eating for three now, which meant: he was eating a lot. Luckily, his mates were happy to provide, bringing him snacks and any craving he had, no matter the time of day. He knew he was a lucky omega.

Now, if only his twin would learn to have some tact.

“Goddamn, Samu. Yer gonna swell like a parade float at that rate,” Atsumu said, watching as Osamu scarfed down another bowl of rice like it was nothing.

Osamu looked up then, staring at his twin as he continued, “Don’t ya gotta be careful about eatin’ like that? Couldn’t ya end up with that thing where the babies get too much sugar?”

Before Osamu could reply, Ushijima interrupted, “That’s gestational diabetes, and that’s rude, my love. Osamu is doing fine, I’m sure,” he said, trying to placate any argument before it could start.

“Yeah, Osamu’s fine, Atsumu. Don’t start,” Aran said plainly, while Kita wrapped his hand around his omega’s.

Atsumu put his hands up in surrender, “Whatever, ‘m just tryin’ to look out fer him and the pups. I wasn’t tryin’ to start anything, I just thought Samu could stand ta skip out on his third bowl of rice,” he said, even as Aran gave him the stink eye and Ushijima sighed.

It wasn’t until they heard a sniffle that their eyes landed on Osamu, who was currently crying with scattered grains of rice on his face, “Yer such an ass, Tsumu,” he mumbled, putting the bowl of rice down as tears slipped down his face. Now that put the entire table into disarray.

Quickly, Kita got up from his seat and crouched down next to Osamu, cooing at him and telling him it was fine, that he could keep eating. Meanwhile, Ushijima was scolding his mate, while Aran interjected occasionally. And Atsumu?

“I – I didn’t – why’re you cryin’, scrub?” Atsumu stuttered, eyes wide as he watched the scene in front of him.

“Atsumu, I told you to leave it alone. Why are you teasing him? You know he’s pregnant and the hormones will make him sensitive,” Ushijima reprimanded, making Atsumu blanch.

Aran joined in too, “Exactly! You know yer not supposed to dig into him now. Ya can’t go back and forth with him like before right now. Why wouldja do that?”

Atsumu gaped at them both, “I – I thought he’d just argue with me! I didn’t know he’d cry! Ya think I wanna make my pregnant twin cry?” he asked, eyes going back and forth between the two alphas and his brother, who was still crying in Kita’s hold.

“You need to apologize, Atsumu,” Ushijima told him, gesturing him to go over to the omega.

With his imaginary tail between his legs, Atsumu walked up to his twin and squatted in front of him, trying to ignore the way Kita was glowering. He sighed, reaching out and wiping the stray grains off his twins face, “Sorry scrubbie. Didn’t mean that,” he said softly, Osamu pouting at him.

“Yer such a dickhead sometimes, Tsumu,” Osamu whimpered, making Kita shush him sweetly.

Atsumu sighed again, “I know, ‘m sorry. I wasn’t tryin’ to start anything. I should’ve just kept my big mouth shut.”

“Yeah, you should’ve. I’d never do anything that’d hurt my pups,” he pouted.

“I know, I know. I’m sorry, Samu. I’ll do anythin’ ya want, okay? Just – just stop cryin’, my chest hurts jus’ watchin’ ya like that. Please,” Atsumu begged, making Osamu sniff back his tears.

He hummed, “Anything?” Uh oh. Atsumu could already feel he was going to regret this.

“Yeah, anything,” he confirmed, waiting for the imaginary anvil to drop on his head.

Just then, Osamu smiled. Lord, he was in for it, “Then I have the perfect job fer ya,” Osamu said sweetly, making Atsumu resign himself to his fate.

Which was how Atsumu ended up working at Onigiri Miya during his off-time, much to Aran and Kita’s amusement.

“I thought you didn’t want help,” Atsumu complained as he washed yet another pile of dishes.

“I didn’t want help from my alphas,” Osamu stated, smug, “I don’t mind gettin’ my stupid alpha brother to do the work for me,” he teased, making Atsumu’s eye twitch.

He glared at the omega, “You set me up, didn’t ya?”

Osamu just kept that innocent look on his face as he replied, “I have no idea what yer talkin’ about, Tsumu. Make sure ta start preppin’ after that!” he said cheerily as he went back to the front of house, leaving Atsumu knees-deep in dishes and unscaled fish. He was going to scream.

Besides all of that, Osamu’s pregnancy was going as smoothly as it could be, given that he was pregnant with twins. His stomach had been expanding faster than he thought it would; leave it to him to have two huge pups growing inside of him. He had even more respect for his mother after dealing with his babies fighting his bladder at 3am.

Every sonogram appointment that he had, his alphas dropped everything to attend, holding his hand and cooing at him as he winced at the cold gel.

“Your pups look good,” the tech said, smiling as she looked around.

“Yeah? They’re doin’ okay in there?” Osamu asked, straining to look at the monitor. The ultrasound tech quickly noticed and moved the screen closer to the omega, who smiled gratefully.

He looked at his pups, his babies, and smiled, “They’re so big already. How’re they gonna fit in here for three more months?”

“Well, if you start to have any issues, we may induce you a little earlier than forty weeks,” she explained gently, “Now, don’t worry, it’s very routine for omegas who are having more than one pup. Nothing for you to be nervous about. We just need to make sure we take care of you, so your pups come out perfect, right?” she said, prompting the alphas.

Kita spoke up first, “She’s right, sweetheart. We need to make sure you’re okay, so that our babies will be okay too.”

Aran agreed as well, “Yup. We’re gonna take such good care of ya,” he whispered, making Osamu smile.

“You already are. It’s okay, I understand. Thank you,” he said to the tech, who smiled back.

She then clapped her hands, “Okay, are we ready to find out the gender, or are you waiting until the babies are born?” she asked.

“No, I wanna know! I wanna know what ‘m havin’,” Osamu said, excitement in his voice.

Kita nodded, “Yes, we’ve been waiting to find out. Can you tell?”

“Yes, I can see it. Are you ready?” she asked, watching all three of their faces light up.

“You’re having girls?” Atsumu shrieked, tears already welling in his eyes. When Osamu nodded, his twin all but ran to him, hugging him tightly, “Oh my god, we’re getting little girls! I’m gonna cry!”

Ushijima patted his husband’s back, “You’re already crying, my love,” he said, before turning to Osamu and smiling warmly, “Congratulations, Osamu. That’s what you were hoping for, correct?”

Osamu smiled, “I mean, I woulda been okay with boys, but yeah. I’ve always wanted daughters, and I know Shin and Aran-kun feel the same. They’d be so good with ‘em too, ‘m so happy,” he said, remembering how hard Aran specifically had cried at the news. Kita had smiled like he’d never seen before, both alphas overjoyed at the news.

“Speakin’ of yer alphas, where are they?” Atsumu asked, finally detangling himself from the omega.

“They’re paintin’ the nursery today and buildin’ some stuff I think.”

“Ah, and they don’t wantcha there?”

“Nope, they’re scared about me breathin’ in paint fumes or something.”

“So doting. So overprotective. You don’t mind it now?”

“Mm, not really,” Osamu said, “I’m pretty big now, so their instincts go haywire these days. I don’t want either of ‘em gettin’ too anxious, so I let ‘em do as they please. Plus, it’s helpful now. My belly makes it harder fer me ta do labor like that,” he explained, laying back on Atsumu and Ushijima’s couch and almost melting in, “Wow, this couch is so comfy. Can I have it?” he asked, just to get a reaction out of his twin.

Atsumu just shrugged, “Sure, but I dunno how yer gonna haul it outta here.”

“We can hire someone,” Ushijima agreed, making Osamu laugh.

“You two are just as insane as my alphas,” he giggled, “I was jus’ kidding. Ya’d really give me yer couch?”

Atsumu chuckled, laying back next to Osamu and pulling his twin to lay on him, “Yer carrying my nieces in there. I’d give ya just about anythin’ ya wanted, Samu,” he said, running his hand through Osamu’s hair absentmindedly.

Ushijima concurred, “He’s right. Anything you need, you can ask us as well, not just your mates. We’re here for you too, Osamu,” he smiled. Osamu couldn’t help but feel emotional about that, sniffling as he mirrored Ushijima’s expression.

“Thanks, you two,” he whispered, so content.

All in all, Osamu’s pregnancy was going well, and he had four very doting alphas looking out for him; something that a lot of omegas couldn’t dream of. When he got home that day, he was delighted to see the pale yellow on the nursery walls, and the two cribs already built.

“Ya even put out some of the décor!” Osamu exclaimed, looking around the room excitedly.

Aran chuckled, pulling the omega into a back-hug as he spun around the room, “We thought we’d surprise ya a bit. You like?”

“I love it,” Osamu said nodding, “It’s so cute. How didja get it done so quickly? I thought it’d take longer than a few hours,” he asked.

“We’re two highly motivated alphas, sweetheart. We could do anything ya like,” Kita replied, voice a bit smug as Osamu giggled.

“Well ain’t I lucky to have two big, strong alphas,” Osamu teased, earning him a kiss from Aran and a laugh from Kita.

Aran buried his face in the omega’s hair, “I think we’re the lucky ones, aren’t we Shin?”

“I couldn’t agree more, Aran,” Kita said, smiling at his two lovers.

All these small moments had given Osamu such joy, such happiness while being pregnant, that he couldn’t fathom being anything but. Unfortunately, as he entered his last trimester, specifically halfway through month seven, that he really became over the whole thing.

“I want ‘em outta me,” Osamu groaned, flipping from one side to another. He’d been trying to sleep for over an hour now, to no avail; his pups kept moving around, leaving it impossible for him to get comfortable. That, plus the fact that his stomach was humungous, was leaving Osamu wishing that he would just give birth already.

“I know, baby,” Aran cooed, rubbing Osamu’s back to try and alleviate some of his pain. They’d tried different things to make Osamu more comfortable sleeping, but nothing seemed to make a difference.

Frustrated tears sprung to Osamu’s eyes, “Aran-kun, help me,” he whined, making Aran purr to try and soothe his mate. He knew there was nothing his alpha could do, but Osamu couldn’t help but cry to him.

Just then, their bedroom door opened, Kita appearing, “Osamu, can you stand up for me?” he asked, making Osamu moan.

“Don’t wanna,” he complained.

“I know, sweetheart, but I found something that might help,” Kita explained, making Osamu still for a second. He then hefted himself up, with the assistance of Aran, who was looking at Kita with hopeful eyes.

Osamu got off the bed with a huff, “This better work. ‘M so tired,” he groaned, making Kita smile sympathetically.

“I know, Samu, I know. Can you turn around?” Kita asked, making Osamu raise a brow at him, before dutifully turning around, “I’m gonna put my hands under your belly, okay?” he explained, leaving Osamu confused.

“Uh, okay?” he replied, looking at Aran and making a face. The other alpha shrugged, watching with rapt attention to see what his mate was going to do.

Kita put his hands under Osamu’s belly, before saying, “Okay, take a deep breath for me, sweetheart.” And again, Osamu did as told, when he suddenly felt a huge weight lift from him, literally.

“Oh my god,” Osamu said, surprise coursing through him as he felt so much relief, “What didja do, Shin?”

“I saw online that a way to relieve your pregnant partner’s pain is by physically holding their belly for them. I thought that maybe if I got you some relief, it would be easier for you to sleep after,” he explained, all while carrying the weight of his twin girls.

Aran commented then, “That’s amazing. We can do that every night before bed then!”

Osamu sighed, “I’ll sleep like a baby every night then. I can feel myself fallin’ asleep just like this,” he breathed out, slowly swaying. Aran was quick to get up and steady his omega’s shoulders, keeping him upright.

“Careful now, baby. Don’t need ya tumblin’ over,” he teased, making Kita laugh behind Osamu.

Osamu just hummed, unable to care about any teasing. He just felt so good. He didn’t realize just how much pressure and weight was on him until Kita lifted it off, and suddenly he felt more relaxed than he had in months.

After almost a half hour, Kita gently set Osamu’s belly back down, before slowly shuffling his lover into bed, helping him lay down. Osamu all but melted into their bed then, snoring almost immediately. Both alphas laughed softly, glad that their mate could finally sleep comfortably, before cuddling next to him on either side and falling asleep themselves. That was quickly added to their routine after that night; before bed, either Aran or Kita would hold Osamu’s belly for at least twenty minutes. It was an easy sacrifice, even if it made their biceps burn; anything for their omega and his comfort.

And like that, the rest of Osamu’s pregnancy continued on smoothly, only running into little bumps in the road like Osamu’s feet getting so swollen he couldn’t wear his shoes anymore (he cried until Ushijima of all people bought him some luxurious pairs. Osamu had preened while Atsumu had whined about his twin being spoiled by his alpha) and him being unable to hold his pee (they’d cleaned up quite a few accidents, much to Osamu’s embarrassment. Neither of his alphas cared at all).

The only thing left?

“Holy shit,” Osamu gasped at their weekly family dinner, making all four alphas look his way. He’d been putting some dishes in the sink when he felt a gush of something fall from his body.

“What? What is it, baby?” Aran asked, rushing over to his mate, Kita on his tail.

Osamu blinked a few times, “Well. Either I just peed a lot, or. My water broke?”

It was silent for just a second, before, “Holy shit!” Atsumu shrieked, and that put everyone in motion.

Within a few minutes, his alphas had collected the baby bag, gotten Osamu into a new pair of pants, and loaded their car to head over to the hospital, all while Ushijima cleaned up the mess on the floor (that man was truly a saint). The ride there was tense, as Osamu’s contractions had started and he was really feeling them.

“What the fuck,” he groaned, Aran holding him back against the seat as another one reigned over him, “This – oh my god – it’s gonna be like this the whole time?” he screamed, squeezing his eyes closed.

“Yer alright, sweetheart, just breathe,” Kita cooed, making Osamu groan.

He whined, “I am not alright, Shin. These babies are givin’ me hell!”

Atsumu piped up then from the front seat, “Well, we did this to Ma, so I guess this is yer karma,” he mused. He could hear Ushijima sigh next to him as he expertly drove through traffic.

“Yer gonna get yer karma right now if ya don’t - ,” Osamu growled, before another contraction came and he groaned.

“You can beat ‘im up later, baby. Let’s focus on gettin’ our terrible two outta you first, huh?” Aran placated, rubbing Osamu’s shoulders and trying to get him to untense.

After that, the car ride blurred into Osamu screaming and the rest of the alphas trying to calm him down, sans Atsumu, who Ushijima was keeping a firm grip on to not say anything out of pocket. They thankfully arrived at the hospital quickly, and were immediately rushed into a room while Osamu put on his gown. Atsumu was quick to help, lacing it up carefully.

“Wow, I can see yer whole ass,” he said plainly, making Osamu groan in pain and annoyance.

“You fuckin’ –“ Osamu snarled, before he was being turned around and hugged.

Atsumu buried his face into his twins shoulder, “Yer gonna be fine, ‘kay? Give the twins a kiss fer me when they come out,” he whispered, before pulling away, “And you better come back ta me, ya hear?” his voice cracking on the last word.

Osamu froze for a moment before chuckling, “Don’t worry ‘bout me. We Miyas are built sturdier, ain’t we?”

That made his twin smile, before pressing a kiss on Osamu’s temple and leaving the room, walking to the waiting room where Ushijima was. Aran and Kita were then brought in, both alphas in surgical gowns for some reason.

Osamu made a face, “What, are you two takin’ this baby outta me?”

Aran snorted, “No, but we wanna catch the little ones when they come out, if that’s okay with you,” he explained, making Osamu’s eyebrows shoot up in surprise.

“That’s okay?” he asked, looking at the nurse who ushered them in.

“There’s no reason they can’t, unless you’d rather they not,” she explained kindly.

Osamu shrugged, “I don’t mind, as long as I can switch off holdin’ yer hands while the other catches,” he said, making everyone in the room laugh.

Kita pressed a kiss to his temple, “Of course, sweetheart. We’re gonna be right here with you.”

And with that, two hours passed as Osamu’s body got ready to give birth. Through it, his alphas held his hands and cooed at him, encouraging him through it all. It took a while, but then, it was over.

“Here’s the first one,” Aran said, voice shaking as he held their first daughter in his hands.

Osamu gasped for air, “That’s Airi,” he huffed, looking over at his daughter and smiling, despite his exhaustion.

“And here’s our second,” Kita said softly, tears pooling in his eyes as he got closer to Osamu.

“That’s Eri. Our two girls,” Osamu mumbled, tears slipping down his cheeks as he looked at both his daughters, a beautiful mix of all three of them.

Both alphas gently put the girls in both of Osamu’s arms, the omega sobbing the second he got his hands on his pups, his girls. He sniffled, “They’re so beautiful. And so little. They were really this little inside of me?”

The doctor chuckled, “They must’ve felt way bigger, I’m sure.”

Aran wrapped his arms around Osamu and Airi, while Kita did the same with Eri, “Thank you, Osamu. For giving us our dream. Our girls,” he cried, pressing wet kisses to the side of Osamu’s face.

“Our little girls. Our little family,” Kita sniffled, holding Osamu tightly and helping him cradle their daughter.

Osamu just smiled, pressing kisses to both girls’ foreheads, “That’s from yer Uncle Tsumu,” he mumbled, so content at that moment, knowing that he had his family right where he wanted them.

“They’re so freakin’ cute, ‘m never gonna recover,” Atsumu sobbed, full-on crying as he carried Eri in his arms, bouncing her.

“They are very adorable, I agree. Airi-chan looks a lot like you and Osamu-san,” Ushijima said softly, cradling their firstborn in his arms carefully.

Osamu chuckled, “She does, doesn’t she? She’s got our hair and eyes, but Shin’s eye color and Aran-kun’s lips. And Eri-chan’s almost the same, but she’s got my eye color,” he whispered, watching as his twin and brother-in-law held his daughters.

“She’s got a little white in her hair too, like Kita-san,” Atsumu whimpered, making Ushijima huff a laugh at his mate. Atsumu whined, “Don’t laugh at me, Ushiwaka, these’re our nieces! I’m allowed to be a little emotional!”

Ushijima conceded easily, “You’re right, my love. This is an emotional day,” he said, looking down at the babies with an easy smile on his face.

“I wonder if they’ll both get tall like Aran-kun,” Atsumu mused, cooing at Eri when she stirred.

Osamu sighed, “I don’t care either way, as long as they’re healthy and happy.”

“You too, Samu. You gotta stay healthy and happy too,” Atsumu added, Ushijima nodding along with him.

“Yes, you should take it easy. We’ll be available at all times to help with anything, so please don’t worry. We are both prepared to clean the house and make meals daily, so please rely on us,” Ushijima tacked on, making Osamu laugh.

He smiled gratefully at them, “Thanks, you two. I couldn’t have done it without ya.” The smiles he got back warmed him from the inside out, ten times over.

And when his mates came back to the room, the takeout that Osamu had requested in hand as well as some other treats, Osamu knew that he was well taken care of. He smiled when Aran pressed a kiss to his temple, while Kita did the same on the other side, before they took their daughters from the other two.

With Eri in Aran’s arms and Airi in Kita’s, Osamu just basked in the new life journey they’d started. And when they crowded around him, opening up the takeout containers and began feeding him while holding their children, Osamu knew; there was absolutely nothing to fear. He had his whole family with him, after all.
