*This is a repost, I've used a different method, so I hope it is not gibberish!*
This is an extra for my omegaverse fic An Unexpected but Happy Family this fits in the last chapter, and has ended up detailing their vow renewal, the last/only planned pregnancy, Eulalia and Fabian's first day in school, Dazai and Chuuya's uhh war with some of the parents, and a bit around the birth/first few months of their final children (again, the actual birth is skipped)
If you don't want to read that first to sum up:
Firstly, I don't know when Odasaku died, and I completely disregarded their official birthdays. Anyway: Dazai and Chuuya are fated mates, Dazai becomes pregnant with their first child (twins) when they're 18, he finds out 6 weeks after Oda's death, they get married the same day as their 8 week scan (Chuuya promises a lavish vow renewal on their 5th wedding anniversary) per canon he stays hidden, starting work at the ADA 6 months later than canon, just after the twins turn 2. The same week he starts he finds out he's 6 weeks pregnant with quadruplets (he becomes freelance for the ADA at 4 months pregnant because he can't take leaving his kids, and would rather be a stay at home parent)
Chihiro is their neighbour, she's in her 60's and is one of those little old ladies who's taken a liking to Dazai, Chuuya and their family. (She and her husband were also fated mates)
This starts the day of their 5th Wedding Anniversary vow renewal (as their first kids ended up born in August, I think this is set around April) their twins are 4 and a bit, their quadruplets 2. Chuuya and Dazai are 23. Yes I know Obaane-san isn't a word, I just liked the idea of Koyou trying to get them to call her Oba-san (grandma) but Dazai and Chuuya constantly calling her Ane-san confusing the kids who just ended up smushing the two together.
Chapter 1
They ended up choosing a Shinto Blessing for their vow renewal, the ceremony involving just them and their six children. They wore traditional clothing, with Ane-san picking their outfits, the three boys were wearing pale trousers, dark tops, and elaborately decorated kimono style jackets, the three girls were wearing brightly decorated kimono's (Chuuya would bet money than Ane-sans own kimono would be complimentary to the girls.)
They invited members of the Port Mafia, Armed Detective Agency and Chihiro's family to a big party in the evening, the children eager to attend their first 'grown up' party. The party wrapped up at 9pm, the invitees from the Mafia needing to get to work, and the children were happier to leave because everyone else was.
Ane-san had offered to babysit their children for the weekend so they could have a honeymoon. Dazai and Chuuya tucked their children into bed, before getting a taxi to Chuuya's apartment, they had chosen to spend the first night there as it allowed Chuuya to have a drink (Dazai hadn't touched alcohol since the beginning of his first pregnancy) before they made their way to his secluded cabin for the rest of their honeymoon. They had thought about going to a Hot Springs resort, but no local resorts allowed omega's and they needed to be close by as Dazai was never good at leaving their children for long.
Paying the taxi driver, they made their way into Chuuya's apartment block, Dazai pinning him to the wall and kissing him the second they got into the elevator.
"Eager, aren't we?"
Dazai moaned, "I think," another kiss, "I think my heats starting,"
"Are you sure? It's only been two weeks since your last one and you've never been this early,"
Dazai grabbed Chuuya's hand, pulling it round to feel the slick soaking the back of his trousers,
"I think it started just as we left the house,"
They exited the elevator, Dazai constantly trying to touch and kiss Chuuya as he fumbled to open the door to his penthouse suite. Getting into the apartment Chuuya knocked on the lights and set the security system, Dazai already trying to strip off his clothes.
"Dazai. Wait."
"But Chuuuyaaa"
"I haven't taken a pill, and I don't have any here. Unless…?"
"I haven't changed my mind since our discussion, it's your choice Chuuya,"
After Dazai's last heat Chuuya surprised him by bringing up the idea of them having more children, there was roughly two years between the twins and quadruplets and he was beginning to feel broody. Dazai surprised him by agreeing, despite the hell of the quadruplets birth and first week home, he was ready for one last pregnancy (as he was likely to have twins or quadruplets again, they felt eight or ten children would be a big enough family for them.) They decided to start trying at Dazai's next heat, feeling a bit strange that they were planning a pregnancy, rather than being surprised when Dazai started being sick. They had wanted to discuss it again before Dazai's next heat to make sure they both definitely wanted it but Dazai's body had other plans.
Chuuya nodded, pulled Dazai into a hot, sloppy kiss. Dazai grabbed Chuuya's hand, placing it on his stomach,
"Put a baby in me then," he smiled,
Chuuya lightly slapped him,
"Urgh, not if you're going to use cringey lines likes that Dazai," he laughed.
Dragging Dazai into the bedroom, Chuuya pushed him onto the bed. Their omega and alpha instincts taking over…
*Sorry! My attempts just went really badly, maybe some other day, just know Dazai's a whiny impatient brat when he's in heat and they spent all night doing basically everything and anything, with a few showers thrown in-between, and a few hours' sleep after his heat dies down*
Chuuya made his way into the kitchen, Dazai was making coffee for the both of them, wearing nothing but a pair of boxers. Using his ability, Chuuya floated up behind Dazai wrapping his arms around him as he came back to the ground, kissing the back of his neck,
"Good morning,"
"I think you mean afternoon," Dazai laughed
"Do you still want to go to the cabin?"
"Hmm, it's quite a bumpy road and I'm a bit sore from last night,"
"We can stay here then? Have an afternoon doing nothing? Maybe you'll be up for more tonight…?" Chuuya suggested, running his hands over Dazai's stomach, smiling to himself at the thought that their next babies could already be growing, "unless you want to go back early?"
"No, the quiet is nice, and I think Ane-san may set golden demon on us if we ruin her time with them, she was quite looking forward to it,"
"Okay then, are you sure you're okay? You're still really hot and you're never this calm away from the children."
"I'm fine, I knew we would be leaving them this weekend so I felt more prepared. Chuuya worries too much" he moved to kiss Chuuya, "I'm just tired, honest,"
"Fine, I'll go grab a blanket and some movies,"
Back home and Chuuya found himself more clingy than ever, he felt the urge to protect Dazai, to be near him at all times. It was out of character for him and he couldn't stop it, even when he could tell it was starting to drive Dazai mad.
It was two weeks after their vow renewal, all six of their children were tucked into bed, and Chuuya had the night off. They were in the shower, Chuuya pining Dazai to the wall and kissing him, his hands kept coming to rest on Dazai's stomach, Dazai batting his hands away every time
"Will you stop pawing at me? I've barely slept and I'm not in the mood," he grumbled, Chuuya stopped, the kids had been off this week, not particularly unwell but not right either, and as he worked some unexpectedly long nights Dazai had been the unlucky one up with them, but
"It's been two weeks, and you" a kiss, "look," a kiss, "so hot tonight,"
"No." Dazai finished rinsing his hair and got out of the shower, leaving Chuuya to finishing washing by himself.
Chuuya sighed, so much for getting Dazai in a good mood before his request, he turned off the shower and made his way over to Dazai, who was pulling on his pyjama's
"I'm sorry, I know how hard you work with the kids, and sometimes I get a bit carried away"
"It's fine," Dazai turned to pull Chuuya into a kiss, "it's just not knowing what's wrong with them is frustrating, but at least they're getting better, and it's totally your turn tonight" he smiled.
Chuuya put on his pyjama's, before pulling out the box he'd hidden in the cabinet early,
"Dazai?"
"….Yes?"
"Did you know omega pregnancy tests start at two weeks?"
"Chuuya, my last two pregnancies were essentially accidents, why would I know that?!"
Chuuya ignored him, continuing, "Well they do, and I was wondering if you would take this?" he handed the box to Dazai, "the lady in the pharmacy said there could be a false negative, but for most omega's it works fine, I thought it would be nice to have the news to ourselves for a few weeks," he smiled,
"You're awfully convinced this is going to be positive,"
"Just humour me, please?"
Dazai took the box, waving Chuuya away "Shoo, I don't need an audience,"
Chuuya complied, making his way into the bedroom, Dazai joined him a minute later, test in hand, he placed it upside down on the dresser,
"Put a timer on for 3 minutes,"
They waited, Chuuya fussing with his hair, thankful it was warm enough to let it air dry.
The timer went off. Chuuya was practically bouncing with anticipation,
"Ready?"
Dazai nodded, he flipped the test over – pregnant. He pulled Chuuya in for a cwtch, excitement finally kicking in. Chuuya kissed him,
"Congrats Dazai"
"I'm glad you were right," he smiled.
After finding out Dazai was pregnant Chuuya's clingy behaviour got worse. He had taken to applying lotion to Dazai's upper body every night, wanting to take in every little change to his body.
It took three weeks of this for Dazai to snap, he was now five weeks pregnant. They were settled in bed, Chuuya had worked till the early morning so had been given that night and the next night off. He kissed Dazai before trying to pull his top off, Dazai grabbed his hands,
"No"
"It's just so I can put some lotion on, I'm not trying to get in your pants," Chuuya explained, knowing how much Dazai disliked the idea of having sex when he was pregnant.
"I've had enough of you doing it, I don't feel pregnant, I don't look pregnant,"
"Ehh you do a bit…"
Dazai laughed, "I look like I've had a good meal Chuuya," he sighed, "just because I've stopped wearing the bandages doesn't mean the reason why I wore them has left, I'm better with it than I used to be, but all this attention on my body makes me feel uncomfortable. I don't mind it when I have a bump, your attention is for the babies, not me. But right now, my stomach aches, my breasts are sore but not, and I'm too hot, and your hands on me at all times isn't helping."
"Shit, I'm sorry, I didn't think of that, you've been doing so well lately," he paused, "and as this is probably your last pregnancy, and we've never known this early, I can't help but be eager. I love seeing how your body changes as our babies grow," he moved to stroke Dazai's stomach through his top, Dazai turned away, letting Chuuya's hand fall to the bed,
"I don't like it. My body hasn't changed at all yet." He turned off his light and pulled the duvet around him, back to Chuuya, "just leave me alone."
"But…" the rest of Chuuya's sentence was lost to Dazai's snores.
Chuuya woke to his alarm chirping, it was rare he was woken by that and not one of his children, but he had a 9am Mori mandated yearly check-up at the doctors and he could not miss it. The house felt quiet, Dazai's side of the bed was empty and cold. He found a note on his desk: The kids woke up at 5am, so I'm taking them to the park to wear them out. Hope your doctors goes well. Dazai x. Chuuya didn't know how he'd managed to sleep through a 5am wake up, but was kinda glad he had some more time to work out how to deal with Dazai after the night before.
The kids hadn't really woken up at 5am, they had the decency to let Dazai sleep till 7am, not wanting to talk to Chuuya, Dazai fed them and got them dressed quickly, the quadruplets, still sleepy were put in the buggy, and they made their way out.
"Mama, where are we going?" Fabian asked, yawning.
"Just to the shops, Mama's been a bit" he paused trying to find the right words, "annoyed with Dada lately, and it's not his fault so I thought we could bake him a cake, but we need some more ingredients,"
"Chocolate cake?" Fabian asked,
"Yep, lots of cream and strawberries too,"
"Yay!"
"Are you annoyed with Dada cos your heats soon?" Eulalia asked,
"I…" he was stumped, they hadn't had that talk yet,
"Obaane-san told us how you may be a bit more shouty and easily annoyed when your heats near cos the omega inside you is a drama queen,"
"Ahh, yeah that's why," he smiled, making a note to have a word with Ane-san about what she was telling their children. "Dada's got an appointment this morning so I thought we could sneak out, get the ingredients, make it when he's still out and then surprise him,"
The twins were happy with that logic, they always enjoyed baking days with Dazai. Chuuya had forced him into learning to cook when the twins had started on solid food, as Dazai would spend the entire cooking process hovering over Chuuya to ensure the food was right, despite Chuuya having read the same feeding book as Dazai. It soon became clear Dazai was useless, until they got to the oven – roasts, cakes, biscuits, pasta bake, casseroles, he could make better than Chuuya could, anything on the hob, unless it was reheating something Chuuya had made, was an inedible mess.
Two and a bit hours later and the cake and six cupcakes were made and decorated, all six kids taking pride in the beautiful mess of a cake they had made. Dazai finished cleaning the kitchen before turning his attention to his cake batter and frosting encrusted children, suddenly very grateful for the shower in the laundry room. Just as Dazai was getting them to move, the front door opened,
"I'm home!" Chuuya yelled out.
"Don't come in here!" Dazai quickly moved to the kitchen doorway, Chuuya frozen in the entryway. "Don't come in the kitchen, but can you go and grab some clothes for all of us please? Comfy clothes, I don't think we're going back out today."
"Okay…" Chuuya was itching to ask why, but thought better of it. He started making his way upstairs,
"Oh! And come in the hallway door, we'll be in the laundry room, thank you" Dazai disappeared before he could hear Chuuya's answer.
Chuuya quickly grabbed the clothes and a set for himself, it was unusual that a bath time wouldn't end up with both of them soaked through.
He was right, but half an hour later and all six kids, Dazai and Chuuya were washed, dried and dressed. The cake covered clothes already in the washer.
"Can we show Dada now?" Eulalia and Fabian asked, excited.
"Yep," Dazai smiled,
"Close your eyes," Eulalia instructed, as she and Fabian took a hand each and led Chuuya into the kitchen, the quadruplets following sleepily. They stopped in front of the kitchen table, where the cake sat on a fancy (plastic) cake stand
"Open eyes!" Fabian announced
"Wow! That's amazing!"
"Everyone helped" Dazai smiled, as Chuuya pulled all his kids in for a big cwtch,
"Thank you! Can we try some now…?"
"Hmm I usually say no sweets before lunch, but I guess I could make an exception for today,"
The kids were at their seats before Dazai had finished, he placed a cupcake in front of each of them, trying to remember who had decorated which cupcake, and cut two slices for himself and Chuuya. The kids were too engrossed in their cake to pay attention to their parents' conversation,
"I'm sorry for how I've been acting lately," Dazai said, handing Chuuya his slice of cake, Chuuya pulled Dazai in for a cwtch, placing a light kiss on his lips,
"There's no need to apologise Dazai, although if it gets me cake, I think I need to annoy you more often," he laughed, "I forget that being an omega your hormones like to screw with your head, a lot."
"Oh, you mean the drama queen inside of me?"
Chuuya gave him a confused look,
"Ane-san's been trying to explain heats…" he trailed off,
"Ohhh, that's what she was on about, she was asking if they'd had any questions for us after our honeymoon, with that knowing smile she has,"
"I'm not correcting them yet, I quite like Ane-san's version" Dazai smiled, "how did the doctors go?"
"Fine, all good,"
They had a pleasant day, making a fort in the living room and watching movies all afternoon. The kids, worn out from their early start had all gone to bed early, leaving Dazai and Chuuya with a few hours to themselves. They were sat in the living room, some random anime playing in the background.
"So, the doctor told me why I've been acting so protective over you lately." Chuuya began, "apparently the Alpha side of me is afraid after the ending of your last pregnancy,"
"Why? Nothing went wrong, our children just decided to torture me and my omega instincts have overwritten that into a haze of err pleasantness" Dazai laughed,
"Yes, but," he paused, "you scared me Dazai, that first night home, hell that first week until we found our routine, your eyes got darker and darker, and I know damn well those cuts weren't accidents, I just went along with it, cos honestly you seemed better, more in control after it,"
"Yeah because you suddenly became more attached to me than the babies, and well, I was too exhausted to feel guilty,"
"Anyway, the doctor said both of our behaviours is normal, if we'd known that early for your other pregnancies, we would have behaved like this. Alpha's want to protect their omega from the changes they can sense and omega's have a point where their bodies seem happy that their pregnant and want you to know and until then, well, you turn into a grumpy bitch at the mere suggestion or acknowledgment that you're pregnant."
"Oi!" a mock gasp of outrage, "I'm not a grumpy bitch…often…" Dazai pulled Chuuya in for a kiss, "I'm glad there's an actual reason though, I may get uncomfortable at times, but I love being pregnant with your children, and seeing you smile as my bump grows and the excitement when the babies start kicking, but I can't stop how I've been reacting lately, and I hate it and," he started crying, the sobs cutting off the rest of his sentence, Chuuya pulling him in close, stroking his back to calm him down
"Shh, shh, it's okay Dazai, we only have a week at most left of you feeling like this, we can get through it,"
"Huh?"
"Your about 5 weeks pregnant now, right?"
Dazai nodded,
"So, you usually start throwing up at about 6 weeks, and whenever we've found out our pregnant you've gone straight into yay! Babies mode,"
"Oh, I see, that's not so bad then,"
"God, this must be screwing with your mind if I manage to outthink you," Chuuya laughed,
"Shut it Chibi," Dazai snapped back, before yawning,
"C'mon let's go to bed,"
They quickly settled into bed, it was only 9pm but it had been a long day for both of them,
"I forgot, I picked up the business card for the Mafia therapist you used to see, I know the twins happened and you were too busy to go, but I can drop you off and handle the kids for a few hours if you want to start going again, even if it's just once a month,"
"I'll keep it in mind, thank you" he yawned again,
"Goodnight Dazai," Chuuya kissed Dazai lightly before moving to turn off the light,
"Wait,"
Chuuya paused,
"Can you," Dazai paused, "if you're awake enough," he was struggling with the next words, especially after his outburst the night before, "could you put some lotion on, please? I didn't realise how relaxing it was, and couldn't get to sleep last night without it," he blushed, he hated it when Chuuya was right,
"Sure" Chuuya smirked, filing this win away for another day, Dazai might break if he gloated tonight. Dazai pulled off his top as Chuuya grabbed the lotion, starting to slather it onto Dazai's stomach,
"Ahh cold!"
"Sorry," Chuuya quickly worked it in, trying to warm it up, "hmm you're definitely starting to show a little bit, more than a good meal. God you look so hot Dazai," he moved up to kiss Dazai slowly, "I can't wait till we can tell everyone; can you imagine Eulalia and Fabian's excitement? I hope Cosmo, Tabi, Dante and Alma are excited too though,"
"They're either going to love not being the babies anymore or hate them, or both." Dazai laughed, "your hands feel so good Chibi,"
Chuuya continued, it ended up turning into a massage until Dazai fell off to sleep. Chuuya pulled his top back on, careful not to wake him, before turning the light off and cwtching into Dazai.
Exactly a week later Dazai started throwing up again, halfway through breakfast. Chuuya was quick to assure the kids that Dazai was fine, trying to keep them interested in their own breakfast's. Dazai returned five minutes later, Eulalia and Fabian running over to wrap their arms around him
"Dada says your fine," Fabian stated in a way that implied he didn't believe a word Chuuya had said.
"I'm fine," he smiled,
"You're squishy!" Eulalia announced, hands prodding Dazai's stomach, Fabian copying, Dazai taking a deep breath as the nausea was returning the more his kids touched his small bump,
"Be gentle with him, or he might be sick on you," Chuuya warned from across the kitchen. Eulalia suddenly squealed, excited
"Are you having more babies?"
Dazai and Chuuya exchanged a look, their children's intuition was quite scary on occasion.
"Yep, you'll all have more siblings soon," Dazai smiled
"Yay! Can we come and see the magic pictures again?" Eulalia and Fabian were far too excited, the quadruplets were confused as to why Mama being sick meant they would have more siblings soon.
"Of course, we can go and see them in two weeks."
The rest of the day was spent trying to explain what was happening in a way the quadruplets would understand, the fact that Eulalia and Fabian had been the same age when Dazai was pregnant last helped, and they were looking forward to getting to see them at Dazai's magic picture scan. Eulalia and Fabian ended up attached to Dazai claiming they had magic cwtches that would stop him being sick (it worked for an hour or two)
Two weeks later and they were at the hospital for Dazai's scan, his bump noticeable by now, but he didn't feel as big as he did at this stage during his last pregnancy. Dazai went in alone for the doctor to check everything was alright, he was a bit concerned with how Dazai had been at the start of the pregnancy but was pleased he was seeing a therapist for it. He also wasn't surprised that with six kids already that he and Chuuya had planned for this to be his last. Happy with how Dazai was, the doctor and nurse quickly called in Chuuya and the kids, they had set up three chairs next to the bed Dazai was lying on, Chuuya perched on the edge of the one closer to Dazai, holding his hand, whilst their kids settled in the other chairs.
"Are we all ready to see your new siblings?" the nurse asked as she prepped Dazai,
"Yep!" a jumble of voices answered.
Starting the scan, the images of their babies quickly filled the screen, the kids quickly counting them,
"One…Two! Aww is that it?" Dazai and Chuuya weren't sure which of their kids the last bit was from, but found themselves incredibly relieved it was only twins,
"Good counting," the nurse praised the children, "it is twins, they're both healthy and growing well, basing on your last heat, you're due mid-October"
"Great," Dazai and Chuuya were beaming.
"Can we go and tell Obeane-san now?" Fabian asked.
"Yep," Chuuya answered as he helped Dazai wipe the goo off his stomach.
Ane-san was delighted that they were having more children, she had currently had no interest in kids of her own, but thoroughly enjoyed babysitting and spoiling Dazai and Chuuya's kids.
