Chapter Text
Ochaco announced she was pregnant with her second and third children after a year and a half after Izuku and Katsuki bonded. For some unknown reason, that planted a seed of want deep inside Izuku. Maybe, just maybe he wanted a second child with Katsuki. The alpha hadn't so much as brought it up since before they bonded in fear that it would scare Izuku away. Unsurprisingly, Izuku was grateful for that. Even if time did heal all wounds, his first pregnancy was something that his body remembered no matter how much his mind tried to forget.
Both Mina and Ochaco told him that they couldn't really remember the pain of childbirth or the bad parts of pregnancy and Izuku always thought they were lying; but as he saw Camie and Himiko cradle Ochaco's belly and talk to the baby, Izuku thought about how nice it would be to be in that position again. When he realized what he was thinking it scared him completely. Why now when things were going so well? Maybe it was because things were going so well that his mind wandered to what it would be like to actually have a mate through pregnancy and beyond. Not just any mate, but the only person he'd ever wanted to go through this part of his life with.
Instead of burying it deep, he decided to lean into it. He didn't hesitate to make an appointment with his doctor to check on his health. It would do no good to get his hopes up if it wasn't possible or if it wouldn't be good for him. No one would benefit if he got hurt over this and it would absolutely gut him if it impaired his ability to be a good parent to Mai.
"Well, your check-up came back completely fine," Izuku's doctor smiled at him.
A medical resident named Dr. Hagakure assisted his primary doctor when he was pregnant with Mai and after he retired Izuku kept going to see her. Izuku could only sigh in relief. There came a point where all that mattered was that your body wasn't falling apart.
"What I'm most concerned about is the fact that you want to get pregnant again." Hagakure trod carefully. While it wasn't any of her business to get involved in the choices that someone else made with their body, she remembered how much Izuku hated it and how much it affected him.
"I'm in a better place now with an alpha who takes care of me." Izuku beamed.
“If you’re sure,” she smiled back. “I’ll make this short, there’s nothing wrong with your fertility, but because your omega had a hard time during your last pregnancy, it might be more difficult to get pregnant because of the increased anxiety and stress that your body might feel because you’re actively trying to conceive.”
Izuku nodded, expecting this outcome. “I expected as much, I just wanted to know if it was possible and if it wouldn’t be too hard on my body. We haven’t really talked about it, but I know that it’s something that we both would want.”
Hagakure finished her notes as she listened to her favorite patient.
“And if it doesn’t happen,” Izuku continued, “Then it wouldn’t be the worst thing in the world.”
“Sometimes,” Hagakure turned to smile at Izuku, “things come when we least expect it. It’s best to let everything run its course.”
“Whatever happens, happens.” Izuku chirped. It was his new favorite life saying after Katsuki came back into his life. All his life he stressed about how his life would turn out when in the end it turned out better than all right.
*
Even if Izuku knew that Katsuki wanted more children, it was only decent to ask him if he wanted to try for another. Last time neither of them really knew they would end up pregnant, so trying for it would be something new for the both of them. Instead of just texting the alpha the question, Izuku decided to make it more exciting.
On his way home from the doctor, Izuku picked up a few items that he was sure Katsuki would enjoy. The alpha was working from home for the day and Mai was over at a friend's home after school to work on a project together and wouldn’t be home until later. It was the perfect opportunity to spring the news on Katsuki that he did, in fact, want another one of his demon spawn.
As he arrived and walked through the front door, he waved and blew a kiss to his alpha who seemed to be too entirely involved in a virtual meeting with a foreign investor. Katsuki subtly nodded at him in acknowledgement from the kitchen table (his temporary home office) as Izuku scampered off to their bedroom. Stripping immediately, Izuku changed into a soft pink mini lingerie dress and thigh-high white stockings. It wasn’t what he usually went for and in all honesty something that Izuku didn’t even try since it seemed like Katsuki preferred him naked, but maybe it would be a nice change of pace.
Well, that and maybe the dress would put Katsuki in the mood to actually make a baby. It was a monumental step in their relationship. Sure, they already had a child, but this was their first time planning one now that he felt like their relationship was strong enough. Taking a few deep breaths, Izuku steeled himself before opening the door and confidently strutting out into the kitchen where Katsuki looked one second away from chewing someone out. Ever since Camie and his assistant left for family leave again, he’s been more than stressed.
“And what I’m saying to you fuckers is th-” Katsuki’s voice died in his throat when he looked up at his mate.
“Midoriya? Is everything okay?” A woman’s voice called out.
Without another word, Katsuki shut the laptop screen and stood up. Izuku shivered at his mate’s gaze, like a predator sizing up its prey. Izuku had never felt more desired than when Katsuki looked at him.
Katsuki walked over and played with the strap on Izuku’s shoulder. “I must’ve done something really good to deserve this.”
Nodding, Izuku smiled slyly. “You’re always such a good boy for me, Kacchan.”
“That so?” Katsuki leaned down to capture Izuku’s lips.
Wasting no time, Katsuki hauled Izuku up into his arms and deposited him on the couch. When Izuku landed he couldn’t help but notice the tent in Katsuki’s pants. It gave him goosebumps knowing that Katsuki always got so hard so quickly simply because of existing.
“And, maybe I want something?” Izuku looked up at Katsuki through his lashes.
And Katsuki was a weak, pathetic man when it came to his omega. “Yes.”
“Yes, what?”
“To anything you want, baby.” Katsuki caged Izuku in between his arms and leaned down to lick at his scent gland.
“W-what if I wanted a pup?”
Katsuki froze and if it wasn’t for his absolutely pleased scent then Izuku would have started freaking out.
“R-really?” Katsuki’s voice shook as he pulled back to search Izuku’s eyes. When all he found was absolute sincerity, tears welled up in his eyes. “A-are you sure? We don’t have to, I’m so happy with what we have now.”
Izuku smiled softly and cupped Katsuki’s face in his hands. “I want one, Kacchan. The reason I couldn’t do it before was that it wasn’t you. I don’t think I could ever have a pup that wasn’t yours and now that I know you’re not leaving, I-I think I want another one.”
Katsuki looked at him skeptically and Izuku gripped harder. "I know I want another. I'm gonna stop taking my birth control, but it still gives you a window to back out if you don't want this."
The fire ignited in Katsuki's eyes as his hands found Izuku's thighs and pried them apart and up. "Then, let's get started," Katsuki smiled wickedly.
Before Izuku could cheer, Katsuki put his thumb up against Izuku's mouth and pushed against those plush lips and let the feeling of Izuku instinctually sucking on it send shivers down his spine. Feeling brave, Katsuki leaned down until his lips were mere centimeters away from Izuku's ear and unleashed every disgusting thought that passed through his head anytime he was lucky enough to see Izuku like this.
"You're gonna look so good knotted on my cock, baby."
Izuku sighed and his eyelids fluttered shut, face heating up at how deep and gravelly his mate's voice was.
"Gonna make you nice and full. Everyone's gonna know what I did to you."
Izuku visibly shuddered and slick began to run down his leg past his lace thong.
"You like that? You want everyone to know what I did to you, what you asked for?"
Izuku's hand began to wander down to his wet pussy and whined when it was intercepted by Katsuki's.
"You know better than to touch what's mine," Katsuki growled into his ear and unshed tears collected in Izuku's eyes and spidered his lashes so beautifully.
Wasting no time, Katsuki unzipped his pants enough for his cock to spring free and tease at Izuku's entrance. "Want my knot baby?"
Izuku nodded around the spit-soaked thumb and bit down when Katsuki pushed through his folds until he was completely sheathed in that perfect tight heat that he would never get used to.
Grinding their pelvises together, Katsuki used his free hand to tweak harshly at one of Izuku's nipples that were peeking out from his top. "Can't fucking wait to see you full of my pups," Katsuki hissed as he pulled out until only the tip remained before thrusting back in.
Twin groans echoed throughout the small living room and the world around them disappeared. All Katsuki could think and feel was Izuku. It was the same for the omega who was lost to the pleasure.
"Can't wait to fuck you so hard you leak milk. Fucking can't wait to see you bounce at my dick when you look ready to pop."
And Izuku never thought about sex during pregnancy, but it did sound incredibly appealing; especially when Katsuki looked at him like he was going to devour him whole.
Saliva had long escaped Izuku's mouth along with the tears. He looked so debauched that Katsuki couldn't help but flip Izuku over and slap his ass hard in a few quick swipes.
Arching his back, Izuku pushed back for more, loving the sting. Katsuki rarely took him from behind, something about the alpha always wanting to see Izuku's face as he came.
"Aw, poor little omega wanna be filled?" Katsuki teased as he quickened his pace.
Izuku couldn't even tell he was nodding until he felt something prodding at his winking asshole. "Then, let's fill up both your greedy little holes."
The second that Katsuki's thumb popped through Izuku's rim, the omega tensed up and before he could cum, Katsuki gripped Izuku's face and turned it enough to face the alpha.
"Cum, baby, cum on my cock."
Eyes rolling to the back of his head, Izuku seized up and stopped breathing as he squirted all over their couch and Katsuki's work pants.
"Fuck yes! My fucking pussy, perfect fucking omega, shit! Gonna knot this perfect cunt and make sure everyone knows who owns it!" Katsuki grunted. He sputtered and eventually his knot finally locked and his orgasm hit him like a freight train. Rope after rope painted Izuku's guts white as his stomach rounded out a bit.
Izuku purred lightly as Katsuki maneuvered them so Katsuki was sitting on the couch with Izuku sitting above him, warming his knot. Katsuki pressed light kisses onto Izuku's scent gland.
"Thank you," Katsuki whispered in between each peppered kiss.
"I love you," Izuku whispered back.
Looking back, Izuku couldn't have wished for a more blissful start to them trying to expand their family. What made it that much better was the fact that Katsuki took the rest of the day off to clean Izuku off and cook for him, making sure he knew that he would always be taken care of. They talked all day and well into the night about names and how excited they were to finally expand their family.
*
As Izuku made his way into the kitchen one random Tuesday, he felt a strange cramp at the bottom of his abdomen. Usually, he would think nothing of it since things like that happened to all omegas, but it'd been pretty consistent for the past few weeks. That combined with other things like bloating, sore nipples, and fatigue made him more than a little suspicious that it wasn’t just him feeling off.
Most of the time he would ignore it and it would go away, but everything seemed to line up too suspiciously for him to simply forget about it. Before he thought too much about it, he took out his phone and texted Mina, Ochaco, and Shoto a simple "I think I'm pregnant," and put his phone away immediately.
Right when he and Katsuki decided to try for more kids he created a group chat with the two other moms in the group and the fun uncle who never wanted kids but would steal yours for a day to satiate any alpha instinct that he had. It was mostly for moral support since it'd been a while since he'd done it last and he'd never tried to purposefully get pregnant before. Maybe they had a special technique that seemed to work that he could use for himself seeing as Mina was currently pregnant with their second at the time and Ochaco wanted more. They all knew that he might have some trouble, but were happy to help where they could and wouldn't get too excited about anything until it was confirmed with his doctor.
The problem was, however, that nothing ever seemed to work or happen. It had been almost a decade since they decided they wanted to start trying again and about three years since they gave up. There were no hard feelings about it, but Izuku was so tired of tracking his unpredictable heats and taking vitamins every day and planning sex with his mate around their very hectic schedules.
Plus, it always made Izuku so sad to see the eagerness on Katsuki's face die out every time a test turned out to be negative. Izuku knew the alpha didn't mean to show any disappointment, but Izuku was beginning to take it personally and when Katsuki noticed the resentment building, he assured Izuku that he didn't care and he'd be happy regardless. It was for the better, maybe the stress of getting older and feeling like he was running out of time was getting to him. Better to put it out of his mind rather than let it fester and make him sick. They'd decided early on that if it didn't happen without medical intervention then they wouldn't pursue it.
So why now of all times was his omega on edge like he'd never felt it before? There was an old wives tale that he always heard about omegas knowing they're pregnant the second it happens. Izuku never put much stock into it seeing as he never realized it with Mai and every inkling he had these past few years had been wrong, but his body seemed to be telling him otherwise. Not half an hour went by after he sent that text did Mina, Shoto, and Ochaco arrive at his home with a couple of pregnancy tests, some tea, and a whole lot of snacks.
"Ready, mommy?" Shoto deadpanned.
Izuku could only roll his eyes. Everyone hated that joke and it only seemed to encourage the alpha that much more.
"But first your snack," Mina pulled a plain donut from one of the bags and handed it to Izuku. "You've been losing weight and if you're gonna carry a baby then you need to bulk up!"
Izuku could only clench his jaw as he added another symptom to the mental checklist he had going. He also lost a lot of weight when he was pregnant with Mai; maybe this was the real deal.
"No time," Izuku's voice wobbled. "I just need to know, okay?"
Ochaco nodded and handed him the test. Wishing him luck, they stayed behind while Izuku made his way to the bathroom. The entire home was filled with an anxious scent that the three of them had unfortunately grown used to.
"I hope he is pregnant," Shoto mused. "I want another."
Mina snorted and Ochaco couldn't help herself. Shoto always seemed to know what to say at the right moment. What made it better was that Shoto never had any intention of lightening the mood or making things better, he was just truly speaking his mind.
"If it's a boy do you think they'll name it after me?" Shoto placed his finger to his chin and pondered seriously despite the snickers from the two girls.
"Over Kacchan's dead body," Izuku appeared. "And please don't ask him, I can already hear him complaining about it." He whined and he ran his hands over his face.
"What did the test say?" Shoto changed the subject.
All he got in response was a shrug. "I'm kind of too scared to look at it."
Ochaco smiled sympathetically. "Well, what's the worst that could happen? Worst case you're not pregnant and can go find out what's actually up with you, best case is you end up with another gremlin."
Gremlin was right. Mai was so sweet until she hit her pre-teen years and presented an alpha. In hindsight, it shouldn't have shocked him so much to see her be an exact copy of her sire just as Katsuki was a copy of his. Despite Izuku's prayers that his genetics would influence her too, he was wrong. She was never rude or disrespectful towards him, but she and Katsuki always seemed to butt heads. One minute they were best friends and the next Katsuki was sleeping on the couch because Mai wanted the nest all to herself and her mother even if she didn't sleep there as much anymore.
Taking a deep breath, Izuku nodded. "You're right, you're right." It took all of his strength and the knowledge that his pack was literally behind him as he made his way back to where his fate lay.
Before his anxiety could get to him, he flipped the test over and immediately broke into tears.
"I-I'm pregnant."
*
It didn't begin to feel real for Izuku until the tests that Ochaco brought him had all been taken and all read positive. Shoto and Mina insisted that they spend the night as her children were a little older and could survive a day without her unlike Ochaco and her almost-four-year-old.
Katsuki and Mai had just left for an extended trip at the behest of an exhausted Izuku who couldn't take three bickering for a second longer. They didn't even fight about anything of substance, it just seemed like they loved to fight for the sake of it. To make matters worse, his usual doctor was out on vacation for just as long as his family was away. So it became the job of his pack to keep him sane until Izuku could decide on how to tell Katsuki.
The week was filled with too much takeout and binge-watching old reality TV shows that they hadn't caught up on in years. It proved to be so great a distraction that when Katsuki and Mai got back all Izuku did was greet them off-handedly as he finished his discussion with Mina about one of the girls in the show and almost completely forgot why she was even there in the first place.
Once Mina had been cleared out and Mai was settled back into her room, Izuku took the opportunity to let his first pup know about what was going on before anything else. She used to ask for a sibling a lot after Ochaco's first son was born, but after a few years she stopped completely and Izuku could not understand what happened. No matter how much he asked her about the change she just refused to say anything about it.
Now, years later, he hoped she would still be excited about it.
“Hey,” Izuku called out to her.
“Hey,” She replied distractedly, looking through the photos that she took on her phone of nature, different rocks, and selfies of her and her dad.
“Have fun?” Izuku smiled sadly. It suddenly hit him that she was no longer going to be his only little pup.
“I guess,” She shrugged. As she grew she started to repress her emotions more like Katsuki. It was just her personality but Izuku could see that she was more than happy about the trip as she made a picture of her and her father on top of a hiking trail her lock screen wallpaper. As much as it saddened him to see her replace one of them in the garden Izuku used to take her to as a baby, he was happy that their relationship was mending.
“I’m glad, I know you needed a little vacation from this place.” Sitting on her bed, he immediately pecked her on the cheek. “Wanna know a secret?” He whispered.
That immediately cracked her iron wall. As much as she muted her feelings, Izuku could always tell what he was feeling. It was only the two of them for so long, how could he not?
“Remember when you used to want a sibling?”
Mai looked at him for a second before she gasped. “W-what?!”
“I haven’t talked to a doctor yet, but I took a few tests and so far they’re positi-” Izuku was engulfed in the embrace of his daughter before he could finish.
“When did you find out? Why didn't you wait for me?!” She sniffled. She’d always been protective of him and now even more so since she presented as an alpha.
"I just wanted to make sure that I wasn't dying!" He laughed as he pulled her in for a hug. "I hope you're not mad."
"Of course I'm mad! You didn't even tell me this could still happen. I gave up hope when I was like 12." She pouted.
"I didn't think so either. Not to gross you out with too many details, but it really did just happen by accident, so when the test was positive I thought I was dreaming."
One thing that never seemed to change about Mai was that she always viewed Izuku as an extension of herself. Without any warning, she shot her hand out and felt around Izuku's stomach. Even after all those years she and Katsuki were the only ones he was comfortable with touching him like that. Mai didn't count though, not when she came from there.
It looked like he'd have to get used to one more touching him too.
"How long?" She asked.
"I'm not sure, I have an appointment tomorrow. Wanna come?"
That seemed to perk her up. "Really?"
"On one condition; you help me tell your dad afterward."
Searching his eyes for a second, she cracked a wide smile. "Deal."
*
"Well," Hagakure entered the room where Izuku sat atop the table, "it looks like you are indeed pregnant!"
Both Izuku and Mai could not contain their excitement. Because Izuku didn't have regular heats and he couldn't pick a date of conception since he and Katsuki were very active, it was hard for the doctor to be able to determine how far along Izuku was. After Mai made a face at his comment and Hagakure chuckled, she decided that an ultrasound was in order to see just how far along Izuku was.
The doctor let Mai place the gel on Izuku's stomach and let her hold the wand with some heavy guidance. Izuku hadn't seen her face light up like that in so long. If it wasn't his first time seeing the new baby then he would have pulled out his phone and snapped a photo of her.
"Oh! There they are," Hagakure pointed at a small speck on the screen. "Here is the head," she moved the little wand around, "and those are the feet."
Although neither Izuku nor Mai could really make out what they were looking at, they knew it was the newest little Midoriya.
Hagakure gave them a few pictures and sent them on their way with Izuku's next appointment date and the prenatal vitamins that she recommended. "Take it easy. Your body seems to be reacting better than the last one, but I still want you to take plenty of rest and really keep off the stressors."
It wasn't too much of a concern given how involved Katsuki was since he came back into their lives. He continued to prove himself day after day for the past decade and Izuku felt solidly comfortable in their situation.
"So, about telling your dad," Izuku started.
Mai cocked her eyebrow. "I'm not putting on a stupid shirt that says 'big sister' or anything!"
That made Izuku pout. "But it would be so cute!"
As much as Izuku tried to wear her down, she just wouldn't budge. She was her sire's pup after all. The only difference was that Katsuki could never say no to Izuku but Mai apparently could. In the end, they both settled for putting her in a shirt that read "pack alpha" and making a little gift box for Katsuki containing a bright yellow onesie, socks, a beanie, and one of the ultrasound photos of the new pup.
"I can't believe I let you talk me into this." Mai scowled, a furiously blush covering her cheeks and nose. "Don't think you're taking photos!"
Izuku gasped and before he could say anything she folded. "Fine! Just don't freaking share them, okay?"
And that was perfectly fine with him. Now that Mai wasn't so little anymore he felt like there was no need to share so much of her life with just friends as now she had direct contact with them for life updates or anything she wanted to tell him. It made Izuku so happy to see that she was surrounded by people that really and truly cared for her and hoped the same for his newest pup. Now they'd even have little pups to play with.
Izuku wanted it to be a surprise; a good surprise this time rather than the ambush that was the last one. As much as Izuku knew that the situation was so completely different than last time, his omega was still stirring in fear that maybe this wasn't a good idea. Mai, ever so observant, scented her mom, even if she didn't know what was going on or exactly what he was feeling. While she didn't know exactly every detail of their relationship, she knew that they both worked hard to maintain what they had, especially her sire. Izuku never wanted to involve her in their relationship or lean on her in that way. She was their child and Izuku would rather die than abuse or change that relationship.
Both of them were so engrossed in each other that they almost missed Katsuki walking through the door. He wasn't in the best mood and looked ready to tear someone's throat out. Usually he would just start ranting, but the second he saw Mai's shirt his hackles were raised.
"What the fuck is going on?" Katsuki sniffed the air. "Baby," the alpha immediately softened, "what's wrong?"
All Mai could do was roll her eyes. "we have a surprise for you, old man."
"You can't call me 'daddy' like you fucking used to?" Katsuki snorted.
"You were young and not old back then." Mai waved her hand around. "Here, or whatever." She handed him his gift and ignored his dumbstruck face.
"The fuck is this?"
"Just fucking open it, will ya?!" She pulled at her long hair. "Don't make this any more embarrassing than this already is."
Izuku looked over at Katsuki and smiled nervously. "I think you'll like it."
Katsuki eyed them both suspiciously before tearing the box open and stopping dead in his tracks. An unreadable expression covered his face and as the seconds ticked by Izuku's anxiety grew.
"You- I, I missed your first ultrasound appointment?" Katsuki's voice cracked and if Izuku wasn't so relieved then maybe he would have felt bad.
"Kacchan, we're finally gonna have another pup!" Izuku cupped Katsuki's cheeks and kissed his chin.
"I'm such a shitty fucking alpha to let you do this alone again!" Katsuki sniffled, embracing Izuku firmly, but not hard to avoid jolting the pup.
"I'm not alone! I went with Mai."
Katsuki looked at her, mouth agape. "You little traitor, how long have you known?!"
Shrugging, she continued scrolling on her phone. "I don't know, like a week?"
And before Katsuki could argue any further, Izuku pulled him in for a chaste kiss. "You can sulk later, today, let's just celebrate. It's been so long and the doctor said we're already almost to the end of the first trimester. I didn't know until about 2 weeks ago, so this is a good sign."
And as hurt as Katsuki was to be the last to find out, now he could let it sink in that this thing he'd wanted for years was finally happening for him, for them.
*
The love that Izuku held for Katsuki was strong, durable, enduring, and never-ending, but as much as he loved Katsuki, the alpha was getting on every single one of Izuku's nerves. The day after Izuku broke the news to Katsuki that he was pregnant he became completely and utterly insufferable and hadn't stopped since.
Izuku was now almost six months pregnant with the tiniest bump to his stomach. Katsuki had completely forbidden him from going to work or working despite Hagakure giving him the green light to continue his normal activities. He couldn't even get up in the morning without Katsuki snapping his eyes awake and practically carrying him to the bathroom or wherever he wanted to go.
"Don't step on the floor without shoes, it's too cold!"
"You need to fucking dry your hair properly before you go to bed."
"What do you mean you want to go for a walk? There's supposed to be a full moon out!"
"Wait, don't eat that shit yet! You need to wait for it to cool down first so you don't burn yourself."
Katsuki was even too scared to have sex with Izuku at first which left the omega to just masturbate any chance he got. After the morning sickness ended it was all Izuku could do to not go absolutely feral and rip Katsuki's scent gland out of his throat. As ashamed as he was to admit it, giving Katsuki the cold shoulder until the alpha would fuck him again seemed to work.
Now, either his mouth or finger was always attached to Izuku's clit, getting him off and Katsuki's knot was usually plugging Izuku's swollen hole. No matter how many orgasms he had it just felt like never enough. Katsuki was a trooper, he'd never not been able to keep up with Izuku or his stamina before; but now that Izuku was asking for it all day every day, the most he could offer was his mouth or fingers to give his dick a break. After a few months it felt like Izuku could only tolerate him when he was being used as a walking sex toy. If that was what his omega needed then so be it. The only other problem was that Izuku had become kind of mean. Katsuki would never complain out loud, but it did hurt his feelings when Izuku went out of his way to terrorize him.
Just that morning as Katsuki was eating a simple breakfast of fried eggs over rice when Izuku came into the kitchen after sleeping in. "Hey baby, do you want anything to eat?" Katsuki blew on his hot food.
Izuku had never been a breakfast person, especially after becoming pregnant. The omega took one look at the sink with two pans and a spatula in it and back at Katsuki's simple breakfast before walking over and knocking it off the table. Just as soon as he'd walked in, Izuku turned around and stomped back into his room, and slammed the door shut.
As shocked as Katsuki wanted to be, he just wasn't. With a sigh, he got to work cleaning his breakfast off the floor before finding a stale cereal bar that he knew was well past expired and praying he didn't get sick from it. All he wanted was to be a supportive alpha to his pregnant mate and he couldn't even do that right. It was hard for him to give Izuku space because he just wanted to make sure his mate was taken care of.
Katsuki found himself apologizing for things he never thought he would have and now he was about to apologize for the crime of wanting to eat breakfast at nine in the morning. As he approached the door and steeled himself to apologize, he heard sniffling on the other side. All of his confusion and apologies went flying out the door and ran into the room to make sure his mate was fine.
"Baby, are you okay?" Katsuki approached their nest.
"Why do you put u-up with m-me?!" Izuku sobbed.
If Katsuki was confused now then he was straight up baffled at this point.
"What the fuck are you talking about?"
I hate you so much because you did this -" Izuku pointed to his barely swollen stomach, "to me! And I know we wanted this but I don't k-know why I'm so mad . You breathe too loud and you're too clingy and, and-" Izuku took a deep breath and Katsuki took the opportunity to reach for his half-finished bottle of water from the night before and give it to Izuku to drink.
Complying, Izuku finished the bottle after a few shaky gulps. "But you still c-care about me and make sure I drink water so I don't get headaches or have to clean or anything." He continued to ramble.
"Well, yeah. I love you, ya fucking shit nerd. Think a little attitude is gonna scare me away, huh? You think I'm some ain't shit alpha?"
And just as fast as he went from anger to sorrow, Izuku was now giggling so hard he couldn't sit straight. Hagakure had explained to Izuku that pregnancy in older omegas could cause severe mood swings and Katsuki was more than prepared to deal with it; especially if it would only be for a few more months. Omegas usually went back to normal after the pup was out, but even if he wouldn’t then Katsuki didn't mind. Izuku always went back to normal after a few hours and he would be more than happy to admit he was being a little suffocating about the whole thing. They both had a lot of grace for each other, more so Katsuki, but it was what made their relationship work.
"Want me to make you some breakfast?" Izuku asked as Katsuki wiped the tears from his pretty freckled cheeks.
"No, but if you want to keep me company while I make my food and maybe something for you and the gremlin inside of you then I would love that very much."
*
Midoriya Kousei was born on a rainy Tuesday night. Only Katsuki and Mai were allowed in the hospital room and thankfully for everyone involved it was a quick delivery. His name was spelled with the Kanji for "light" and "star" and the second he was out both Izuku and Katsuki felt that their family was finally complete.
Both Mai and Katsuki were completely and totally enamored with their mini-Izuku. The only thing that it looked like he inherited from Katsuki was the little red specs in his big green eyes and how clingy he seemed to be with Izuku. After breathing a sigh of relief that both pup and mate were healthy, Katsuki let himself finally be happy for the family that he created.
One thing that neither of them expected was Mai's jealousy over the new pup. Not because Izuku spent all his time with the tiny thing who quite literally couldn't do anything except poop and sleep, but because Katsuki spent any amount of time at all with the pup.
Mai began to sleep in the nest again and when Kousei was just over a month old Izuku placed him in Mai's room for naps so he could get used to sleeping alone. Katsuki would usually sneak over when everyone else was asleep in the nest to have some one-on-one time with his son and obsess over him in peace. As he grew it seemed like he was growing used to Katsuki and wouldn't cry when it was anyone other than Izuku picking him up. His favorite thing was talking to Kousei and watching the pup's eyes roam over Katsuki's face.
"You're getting so big." Katsuki cooed and kissed his nose.
All Kousei could do was sneeze and rub his nose with his covered hands.
"Must be nice to have a new kid who doesn't know about your fuck-ups." Mai appeared at the doorway, sneering at the sight.
While they were still in therapy, Katsuki thought they'd worked through the fact that he was missing for so much of her childhood. It seemed like the scars were still there. Mai knew that her sire loved her and that he was just excited to have a new pup, but it still hurt to see Kousei have what she didn't.
The last thing she expected was for Katsuki to set the pup back down in his crib and make a beeline for her and pick her up like she was the newborn baby.
"Oh, he'll know. I'll definitely make more mistakes, but he's not my first baby, so I got some practice."
She couldn't help but crack a smile.
"If you want me to wake you up every morning with a kiss and cradle you like the little baby you are then so be it."
"No!" She squealed, completely forgetting that they weren't the only two in the home. As Kousei began to cry, Mai tried to get away from Katsuki.
"Nope, let your mom get it, I'm with my other baby."
Sometimes it was okay to indulge her. And he always would, especially if it meant that he could reassure her that this wasn't just to right his wrongs and she wasn't just some consolation prize. She was the prize and just as wanted and loved as Kousei was.
After getting scolded by a very tired Izuku, Mai decided to take Kousei for the morning and spend some time with him and his new baby's scent so Izuku could sleep a little more. Even if she was a little resentful, who could resist the cutest pup with the chubbiest freckled cheeks and matching green eyes that their sire was obsessed with? As wild as their life was, none of them would ever change anything about it.
