Work Text:
Katsuki thought these things were dumb. The halls of the school were always full of preening mothers and loud fathers, boasting how great their kids were to anybody who would listen. Katsuki always felt like he was being studied when he came to these things. The pretty collar locked tightly around his neck always brought unwanted attention to him. An unmarried, unmarked omega with two children was basically unheard of outside the city. This whole parent teacher conference thing just felt like a spectacle for parents to show off and judge each other. Katsuki would have ditched the whole thing if his daughter hadn’t begged him, puffed cheeks and puppy dog eyes to boot, to come meet her homeroom teacher. She absolutely adored them. Katsuki couldn’t imagine any old hag dealing with other people’s spawn could be likable at all but he always had a hard time telling his oldest no when she was really excited about something.
“C’mon, Kaachan! My class is this way!” Mahoro said excitedly, tugging Katsuki’s arm after her.
“Hold on, kid! Your brother’s legs aren’t as long as yours!” Katsuki chuckled, trying to keep Katsuma on his feet.
“Yeah, Mahoro! I can’t keep up!” Katsuma complained.
Katsuki brought both children to a stop. He lifted Katsuma into his arms, propping him on his hip. “Okay, kid. Show me the way.”
Mahoro giggled as she gripped Katsuki’s wrist. They made it through the crowd of parents, students, and teachers. The classroom Mahoro had been spending most of her middle school time in was at the end of the hall. There was a line already formed at the door.
“Must be a popular guy…” Katsuki grumbled to himself.
“All the moms like to ogle at him. My friend, Kota, says it’s because he’s a hot alpha but I don’t see it. I think he’s a nerd,” Mahoro explained with a shrug as if she didn’t drop very loud gossip around the mothers and their mates.
“What’s a hot alpha?” Katsuma asked shyly, rubbing a strand of Katsuki’s hair between his fingers.
Katsuki nuzzled his cheek, scenting him to calm him. “Don’t worry about it.”
“It’s like Grama!” Mahoro supplied.
Katsuki sputtered. “Don’t talk about the hag like that!” He hissed as several sets of eyes found them from around the halls. “Who told you that?”
“I heard Grampa say it. He said ‘I wonder when our son will find a nice hot alpha like you.’”
Katsuki rubbed the bridge of his nose. “Good god.”
Before Mahoro could go any further, their name was called from the doorway. Katsuki had been smart and set up an appointment with the front office. From the dirty looks the other parents gave him as he walked past, they hadn’t read the letter sent home with their kids like he had.
Mahoro bounded into the room with a very happy grin. “Sensei!”
Katsuki froze in the doorway. The smile that greeted his daughter was far too familiar for his own liking. The kind green eyes and the dusting of freckles on his cheeks sent shivers down Katsuki’s spine and his stomach twisting dangerously. The “hot alpha teacher” was an old childhood friend.
The teacher looked up and locked eyes with Katsuki and his face paled except for a painted pink blush over his freckles. “Oh…this must be…”
“My Kaachan! And my baby brother, Katsuma!”
Sensei looked down at his papers and then back at Katsuki. “Um…”
“See? I told you he was a nerd!” Mahoro said to Katsuki.
“Mahoro, don’t be rude,” Katsuki hissed as if he hadn’t called the man at the desk the same thing hundreds of times when they were her age. He took a deep breath and forced a smile to his face as he stepped closer to the desk. “I’m Katsuki Bakugo.”
Sensei stood up and extended his hand for Katsuki to take, “I’m Izuku Midoriya.”
Katsuki was stunned by just how tall and…big Izuku was. He was always a scrawny little runt of a child. His growth spurts were always later, smaller, than Katsuki’s.
He accepted the handshake. “I know…” he breathed through his teeth.
Izuku blushed deeper before releasing his hand and gesturing to the vacant seat across from his desk. Katsuki set Katsuma down on the floor as he sat. Mahoro grabbed her brother by the hand and dragged him to where her desk was, chattering on about her day to day.
“So…” Izuku started awkwardly.
“Has Mahoro been behaving?” Katsuki asked, trying to keep the subject on the kids as much as possible. He couldn’t bare the Other conversation they could be having.
“Oh!” Izuku picked up his papers, adjusting them so they were straight. “She has perfect grades and perfect attendance. She participates very well in class.”
Katsuki felt a bubble of pride swell in his chest. He knew his girl was perfect. He raised her after all. She would be the best.
Izuku set the papers down. “I have no idea why they make every parent come to these things. I really have nothing else to say other than you’ve done a really great job with her.”
Katsuki beamed. “Well! She is mine! Of course she would kick ass!”
Izuku chuckled. “Good to know you haven’t changed, Kacchan.”
Katsuki blushed. “Um…well…”
Izuku’s eyes widened. “I MEAN! Sorry you have! Just…”
Katsuki stood up. “Well, if that’s all we better get going. It is a school night.”
“Wait!” Izuku gasped, standing up abruptly. “Maybe we can…catch up sometime?”
Katsuki raised a brow. “Like a date?”
“No no! Well…maybe if you want it to be…but it can also just be dinner! Friends catching up!”
Katsuki looked back at Katsuma and Mahoro looking at the class pet in the back of the room. He glanced back to Izuku, who looked very much like a strawberry.
“Alright. Let’s go to a bar this weekend. We can catch up over drinks,” he suggested. Something deep inside him, something that had been dormant for a very long time, purred at the bashful alpha perking up at the promise of meeting.
“Okay! Saturday night then!”
Katsuki couldn’t help but flirt a bit, using his physique to his advantage. He popped his hip to the side and looked coyly over his shoulder as his children bounded toward the door. “Call me later and dress nice.”
—-
Izuku fussed with his blazer as he walked into the bar. It was crowded and loud and smelly. He scanned the crowd, looking for a shock of blond hair. He found it leaning on the bar, bright eyes watching the door. Katsuki grinned and waved him over. He was wearing a tight tank top, stretched almost thin over his check and hugging his slight waist. His jeans were high waisted, tight around the hips and thighs to emphasize his hourglass shape. A nice leather jacket and chunky heeled boots topped off the entire look. He was perfect in every way and the alpha inside Izuku growled in satisfaction. That sweet caramel scent danced above all the others right to Izuku. He inhaled deeply before smiling and waving.
“I didn’t expect you to be already here waiting for me,” Izuku chuckled as he sat next to Katsuki.
Katsuki slid a drink over to Izuku. “I haven’t been waiting long.”
Izuku took the drink graciously. They spent the next several hours talking about the time since they’d last met. They talked mostly about Katsuki’s children. He talked animatedly about them. He talked about how Mahoro asked to return Katsuma to the hospital because he cried too much. Izuku listened intently, watching Katsuki talk animatedly.
“Is their…is their dad around?” Izuku asked carefully.
Katsuki sighed. “Nah. They have different dads. I didn’t feel like settling down with anybody but I knew I wanted a family of my own.” He shrugged like it was nothing. “I just haven’t found a mate yet.”
Izuku blinked. Katsuki was always far more independent than anybody he’d ever met. He just hadn’t expected…
“You’ve raised them both all alone?”
Katsuki grinned proudly. “Of course I did! That’s why they’re the best kids in the world!”
The bartender came by and asked if they wanted refills.
“Nah, I shouldn’t drink too much,” Katsuki said with a wave.
Izuku glanced over at him, his eyes drifting to his chest barely concealed by his shirt. Katsuki snorted at him.
“Don’t get too ahead of yourself there, Deku,” Katsuki warned.
Izuku turned bright red. “No! No! I wasn’t!”
Katsuki leaned over the bar, making sure his neckline sagged enough to show his cleavage. “My youngest is almost five. I haven’t breastfed in years.” He smirked as Izuku’s eyes dropped and snapped back up. “I’m not drinking much because I can’t go home to my children drunk.”
Izuku averted his eyes with a deep blush. He was very aware of all the alphas now looking at them, at Katsuki. Their scents were spiking, overshadowing the sweet tempting scent of Katsuki.
Katsuki stood up. “Let me drive you home. I know you walked.”
“It’s fine! I’ll be okay!”
Katsuki leveled his gaze over his shoulder at Izuku. “Let me.”
Izuku simply nodded and followed Katsuki out of the bar. He led him to a very fancy sleek black car at the very back of the parking lot.
“It’s a bit… brave to park all the way out here…” Izuku muttered.
“Not if you already have a plan,” Katsuki replied.
Katsuki unlocked his car and climbed into the front seat. Izuku followed suit, clumsily settling into the passenger seat. They sat in awkward silence. Katsuki made no move to start the car and Izuku made no move to say anything about it. The tension made Izuku restless. He turned towards Katsuki to say something but as he did Katsuki turned too. Their mouths collided in a messy open mouthed kiss as Katsuki gripped Izuku’s face.
Izuku moaned as Katsuki explored his mouth. His hands twitched in his lap, wanting to touch and grab and squeeze. Katsuki climbed over the center console and straddled Izuku’s lap, nearly suffocating him with his sweet delicious scent. Izuku gasped against Katsuki’s mouth, his hands gripping Katsuki’s hips tightly. Katsuki rocked his hips over Izuku’s hardening cock, eliciting desperate moans from the alpha. Izuku tried to fumble with the buttons on Katsuki’s jeans but his hands were caught around the wrists.
“I don’t think so, Deku,” Katsuki purred over his mouth. “I never fuck on the first date.”
Izuku whined. “That can be changed.”
Katsuki laughed. “No, no. But I can give you a taste.”
He leaned backwards, wiggling his hips a bit teasingly. He let his jacket slide down his arms, revealing more of his muscled arms and shoulders. Izuku’s mouth watered as Katsuki tugged the straps and neckline down, letting his breasts spill out.
“C’mon, alpha, I know you’ve been dying to get your hands on these,” he purred, using one hand to lift and squeeze himself.
Izuku couldn’t help the deep possessive growl that escaped his throat as he latched onto one of Katsuki’s nipples and kneaded the other with his hand. Katsuki let his head lull backwards as Izuku tasted and squeezed him. He ground against Izuku’s cock, purring at all the attention he was receiving. Izuku moaned as he felt the vibration against his face. He kissed his way up between Katsuki’s breasts, sucking marks as he went. By pure instinct, he tried to nuzzle at Katsuki’s neck but was met with the harsh metal of his neatly locked collar.
“Not yet,” he warned, cupping Izuku’s face to tilt it up toward him. Big watery green puppy dog eyes looked back at him, pleading for everything Katsuki could give him. “I’ve still got to test you out, alpha. Make sure you’re good to my kids and even better to me.”
Izuku whined desperately, bucking up against Katsuki. “Please, Kacchan. I’m suffering here.”
Katsuki pressed a little kiss to his nose then one to each freckle. “Prove to me you’re the alpha that will do me good. Take care of me.”
“I will, Kacchan, I will I will I will.”
Katsuki kissed him one more time before climbing back over into the driver seat. He turned the car on, the engine roaring to life, and flicked on the defrost to get all the fog off the windows. He readjusted himself back into his shirt. He ignored the way his pussy quivered in his pants from the loss of pressure and friction.
“Tell me where your place is. I’ll take you home, big boy,” Katsuki teased.
Izuku glared at him from the corner of his eye, clearly frustrated by the blue balls Katsuki just gifted him. “You’re still so mean to me, Kacchan…”
Katsuki grit his teeth. “Just testing you…”
That night, alone in his bed, children tucked in safe and sound, Katsuki thought back on the night. By all accounts, Izuku was perfect. If this had been younger Katsuki, he’d have jumped his bones and been pregnant, two cities away by now. But something about Izuku made that seem far too cruel to both him and Katsuki. Katsuki’s body felt like a puzzle piece against Izuku’s in that car. Izuku’s scent of tea leaves and rain fall mixed so nicely with Katsuki’s own sweeter scent. He almost felt safe enough to take his collar off around him.
He rolled over and stared at the light trying to penetrate the curtains. He still felt wound up. He could still feel the pressure of Izuku’s hardness sliding against his own soft heat. The skin on his chest still tingled and ached from the bites and kisses. He ran his hand over his chest, imagining it was Izuku’s, far bigger and rougher than his own. His breath hitched as he trailed his fingers down his flat stomach, twirling them over his womb, imagining another little dancing light there fluttering and growing. His back arched as he dipped his hand lower beneath the elastic of his boxers. He closed his eyes and imagined Izuku, his scent, his thick fingers plunging inside him, the warmth of his breath against his neck repeating his name like a prayer. Katsuki sank his fangs into the fleshy part of his thumb as he curled his own fingers inside himself. He was in deep deep trouble if he could cum simply off imagining Izuku’s fingers.
—-
Katsuki invited Izuku over to his place for dinner. His initial test at the bar ended satisfactorily. Izuku didn’t force himself onto Katsuki, he didn’t act like an alphahole when other alphas were throwing pheromones and checking him out, and he accepted Katsuki’s denials without much argument though he did grumble all the way back to his place.
Katsuki and the kids spent the entire weekend cleaning the house and looking up what to make for dinner. Katsuma made himself very busy cleaning up his crayons and then getting them all out again to make art to show Izuku when he got there. Mahoro helped Katsuki make dessert, standing on a chair with her tablet on the counter.
“So, we should add the milk last,” Mahoro said, pointing to the step in the instructions.
“No, that’s for the glaze. We aren’t there yet,” Katsuki corrected.
“Why is there two milk? There should just be one milk!” Mahoro argued.
“Because they’re two different things, Mahoro.”
“Why is it here then? This is the recipe for the cake!”
Katsuki rubbed the bridge of his nose. “The glaze is still part of the cake.”
Mahoro huffed and jumped off the chair, stomping to the pantry and throwing it open. “This is what happens when people put their whole life story in the recipe!”
Katsuki snorted as he mixed the batter. “Why don’t you start on the crust while I finish this part?” He called into the pantry after her.
“That’s what I’m doing!”
The doorbell rang while Mahoro was finishing up pouring the batter into the crust. Katsuki left her to finish and dusted flour off his hands as he walked over to the door. He opened it to find Izuku on the other side, a big bouquet of very loud flowers in one hand and a plate of haphazardly iced sugar cookies in the other hand.
“I’m a bit early,” Izuku said sheepishly.
Katsuki chuckled and stepped aside to let him in. “No worries. I’m sure Mahoro will find a job for you.”
As Izuku toed his shoes off, Katsuki took the bouquet, sure to sniff it first, and the cookies. He brought the cookies to the kitchen table then went to the kitchen to find a vase for the flowers. Izuku glanced into the kitchen to where Mahoro was now dictating every move her father made and decided he’d hang out with Katsuma instead.
“What are you up to?” He asked as he sat down across from Katsuma at the coffee table.
“I’m drawing,” Katsuma said, not looking up from his art.
“What are you drawing?” Izuku asked as he tilted his head to the side to get a better look.
Katsuma leaned back to let Izuku see his work in progress. In crude crayon art, he had drawn a little family. One figure was tall and drawn like an upside down triangle. Next to that one was a girl with pig tails holding hands with a little boy wearing a superhero cape. Next to the children was another tall figure topped with a cloud of green.
“Is that a tree?” Izuku asked, pointing to the green cloud.
“No!” Katsuma giggled. “That’s you!”
“Me!?”
“Yeah! Kaachan likes you so you get to be part of the family!” He reached over and colored in the green cloud. “Anybody that Kaachan likes gets to be part of us because he doesn’t like anybody but us.”
Izuku glanced over at Katsuki, noticing him frozen with the flowers still in his hand half in the vase. He smirked to himself before going back to watching Katsuma draw.
It took another hour or so before dinner was ready and Izuku found himself helping Katsuma draw. Katsuki stood over them with his hands on his hips. He leaned down and took one of the sheets of paper. The image was drawn by Izuku and colored by Katsuma. It was a surprisingly detailed drawing of Katsuki leaning over Mahoro while she poured something over a bowl. He looked down at the one Izuku was in the middle of drawing. It was Katsuma in a super hero costume perched happily on Katsuki’s shoulder, both smiling brightly.
Katsuki leaned over Izuku’s shoulder and whispered, “you didn’t get my tits right,” into his ear.
Izuku startled, snapping the crayon in half in his hand.
“Kaachan! Look what you did!” Katsuma complained.
Katsuki rolled his eyes. “Sensei can get you all new ones.”
Izuku stood up and stretched. “Oh can I?”
Katsuki put his hands on his hips. “You broke it. You fix it.” He looked down at Katsuma. “Why don’t you go wash your hands and Sensei and I will hang up your art?”
Katsuma hopped to his feet. “Yes, Kaachan!”
The two watched him go off to the bathroom down the hall. Katsuki leaned close to Izuku. “You passed another test.”
Izuku looked at him quickly but he was already bent down scooping up the drawings. He watched Katsuki’s back all the way to the kitchen where he put the drawings up, including the stick figure family, in the highest place of honor. Little magnet pictures of the kids held the art on the front of the fridge. Katsuki turned around and winked at Izuku before helping Mahoro set the table.
Dinner was quick and uneventful. Katsuki sent both kids to get cleaned and get changed for bed while him and Izuku cleaned up.
“So what was this test then?” Izuku asked.
“Whether I felt safe with you around my kids,” Katsuki replied as he handed a washed dish to Izuku to dry.
“I teach and watch after Mahoro every day and have for the last two years!”
“It’s Katsuma that has to make the final decision. He’s a bit more shy than Mahoro is,” Katsuki explained. “He’s little and gets scared easy. I scent him often for comfort but he is just a little ball of nerves.”
Izuku cocked his head to the side and he thought. “He didn’t seem afraid of me. A strange alpha in his home with his mother. Most kids hate that especially if they’re already nervous.”
Katsuki nudged Izuku with his hip. “That means you passed his test.”
Izuku snorted. “What does that mean for me then?”
Katsuki smiled to himself. “Another date. You free next weekend? The kids are gonna be with my parents the entire weekend.” He took Izuku’s hand and brought it up to his cheek. He wasn’t wearing his collar, usually keeping it off at home to scent his kids and prevent it from injuring him. He rubbed Izuku’s wrist against his scent gland before pressing a kiss to his palm.
“What…?”
Katsuki leaned against Izuku’s shoulder. “A gift.”
—-
This date wasn’t meant to be the end all for them. Katsuki wanted to have a nice dinner, watch a movie, maybe snuggle a bit. However, his body chose this time to reawaken. After years of suppressants, his heat hadn’t reappeared after Katsuma had been born. Four years of it never returning and it decided that this was going to be the time to come back. And it came back with a roar.
Katsuki laid curled up in his bed in a tight ball. His entire body felt like it was on fire and frozen at the same time. He hated the feeling of wetness between his legs. His skin felt like live wires and everything that touched him hurt. He cracked his eyes open enough to fumble for his phone. He opened his contacts and smashed the call button under Izuku’s name harder than necessary.
“Hello?”
“Izuku…” Katsuki groaned. Just the sound of Izuku’s voice sent a tidal wave of sensation through his body.
“Kacchan? Are you alright? You don’t sound good…”
“Please…” he whined into the phone. He buried his face in his pillow as his abdomen spasmed.
“I’ll be there in five,” izuku replied firmly.
Katsuki slumped back against the pillows. “S-stay on until you get here?”
“Of course, Kacchan. I’m not going anywhere.”
Kacchan hated himself for whining and begging. It was something he always hated about being an omega. He worked so hard to prove he was strong. He could raise two kids on his own. He could do everything without an alpha. Yet here he was almost in tears because an alpha was cooing sweet nothings at him through the phone.
He kept thinking he should have kept Izuku’s jacket the night he’d come over for dinner to have in his bed in the event this happened. He was also regretting scenting Izuku that night. Perhaps that’s what kicked all this off in the first place.
“Damn Deku,” he groaned to himself.
“I’m sorry, Kacchan. I gotta hang up now.”
“Nooooo.”
“Kacchan, I’m at your door. I’ll be there in a few seconds.”
The phone went dead and Katsuki felt a sob rip through his body. Then his room was filled with the most calming delicious scent he’d ever experienced. Izuku was in the doorway with bottles of water and several blankets Katsuki didn’t recognize from his house. He waited for Katsuki to invite him closer. He made no move to force himself into Katsuki’s safe space. He simply stood there and waited for permission.
Damn bastard passed the final test.
Katsuki reached his arms out. “Izuku.”
It was all the invitation Izuku needed to come and sit beside him on the bed. He set the water bottles on the floor before laying the blankets out in a nest around them both. Katsuki immediately burrowed his head under some of the blankets, inhaling Izuku’s scent deeply until it filled every crevice of his being. Izuku didn’t move, didn’t try to touch him. Ever the gentle caring alpha.
Katsuki peaked out from beneath the blankets. “You passed.”
“What?”
Katsuki grumbled. “You passed every test, idiot. Now come here and do your job.”
Izuku stared at him. “What job?”
Katsuki snarled before grabbing Izuku by the front of his shirt. “You better get naked and fuck me right now. You better fill me with your knot then claim me.” His eyes almost glowed with the fierceness and want of a man on a mission. “I want you to be my mate.”
Izuku couldn’t respond. He simply did as he was told. He pulled his shirt over his head in one single motion. He started fumbling with his jeans and Katsuki growled with impatience.
“Today, Deku!” He snapped before leaping on him. He yanked hard, sending the button flying off somewhere in the room. He grabbed Izuku’s face, forcing their eyes to meet. “Put a baby in me.”
“Wait!” Izuku gripped Katsuki’s shoulders. “You’re not going to run off? Have the baby alone? Raise them alone?”
Another wave of cramps and heat washed over Katsuki, making him moan and grind against Izuku. “N-no. I want you. I want you to be here. You’re the One. Be the father of my children. Be my mate, Izuku.”
It was all he needed. Izuku tugged his pants off, tossing them somewhere in the room. He shoved Katsuki down with his hand on the back of his neck. Katsuki willfully spread his legs, showing Izuku his hot pulsing pussy.
“Please,” Katsuki whined.
“Already ready for me, Kacchan?” Izuku asked, lightly running his fingers over Katsuki’s entrance.
Katsuki shivered violently under him. “Please,” he begged again.
Izuku used Katsuki’s slick to pump himself hard. Katsuki glanced over his shoulder and drooled at the sight of Izuku’s huge cock. Izuku didn’t give him time to prepare himself before he slammed into him. Katsuki groaned loudly as Izuku bottomed out.
“It’s good you like this rough. I can’t hold back anymore, Kacchan. Especially after you teased me on our first date,” Izuku said as he set a brutal pace.
Katsuki hung his head forward, looking down his sweat slicked body. He almost thought he could see his belly bulging with each thrust. Izuku’s hands traveled up his sides before cupping both his breasts. They were tender from the heat and extra sensitive. Izuku squeezed them and rubbed the nipples with his thumbs. The muscles tightened, making them seem even bigger. Katsuki couldn’t make any sounds. His head fell against the pillow and he drooled around panting. Izuku pressed kisses down his spine with each and every thrust and gave each tit a squeeze for good measure.
“I can’t wait…until you smell like me…and you're nice and plump and round with our child…and your beautiful tits are full…until you’re mine,” Izuku almost chanted against Katsuki’s skin.
Katsuki moaned. “Close…”
Izuku’s grip on him tightened. “Me too…”
Katsuki tried to rock back against Izuku, chasing his pleasure. Instead Izuku lifted him, not quite letting himself out of Katsuki’s pussy, and turned him so they were facing each other. With Izuku’s hands on his hips, Katsuki bounced in Izuku’s lap. He held onto Izuku’s shoulder for balance. His tits, bruised and abused, bounced with him. Izuku ran his tongue over a nipple and Katsuki shattered. He cried out as he came, tightening around Izuku’s length.
“So close…” Izuku mumbled.
“Claim me, Izuku,” Katsuki groaned, baring his neck and scent gland to the alpha. “Make me yours, alpha.”
Izuku took the chance and sank his teeth deep into Katsuki’s neck, mingling their scents as he filled Katsuki to the brim. His knot inflated, locking them together. Izuku didn’t release his bite. He stayed there, holding Katsuki tightly against his body. He hadn’t noticed in his climactic high that Katsuki had laid his claim on him too. They didn’t move for a long time, locked together in each other’s arms, until Katsuki leaned back first. He cupped Izuku’s face before kissing him gently at first. Another wave of heat and desire washed over him and the kiss deepened. Izuku gripped his hips and flipped him onto his back against the pillows.
It took the whole weekend, day and night with a few hours of sleep in between, for Katsuki’s heat to slow down. They finally made it out of bed Sunday evening to take a shower, and have sex under the water. Once the water got cold they got out, towel dried, and Katsuki was bent over the bathroom sink. They made it into the bedroom and had at it again against the mirror hung on the wall beside the closet. It took them a while to get dressed but they finally got to the kitchen to make something to eat.
Katsuki stood over the stove, pushing the egg mixture around he’d poured into the pan. Izuku buried his face between Katsuki’s shoulders, wrapping his arms around his waist.
“When are you moving in?” Katsuki asked.
“Mm…” Izuku mumbled against his back.
“Well you know, I’m not letting you go anywhere. Plus we’re only a few blocks from the school. Much better than your place.”
“After school tomorrow,” Izuku mumbled, kissing the new claim mark on Katsuki’s neck. “Too tired today.”
Katsuki smiled and settled back against Izuku’s chest. His heart hadn’t felt this full since he’d held each child in his arms for the first time.
—-
Mahoro and Katsuma didn’t even bat an eye when Izuku moved in. It wasn’t a big deal until Mahoro looked up from the test she was taking and saw Katsuki leaning over Izuku’s desk, whispering something that was making Izuku stare at him with big dopey eyes.
“Isn’t that your mom?” One of her classmates whispered to her from behind.
She turned around and gave him a disgusted face. “Shut up and take your test.”
She was incredibly mortified and kept her head down the rest of the day. When she got home, Katsuki was looking through some old pictures from a box they normally kept in the attic.
“Kaachan! Why were you at school making googoo eyes at Sensei?” Mahoro demanded, sitting across from him at the table.
Katsuki looked up with a soft smile on his face. She remembered that look. It was the same look he gave her when Izuku moved in. It was also the same look he gave her when he told her she was going to be a big sister.
“He forgot his lunch so I brought it in,” he replied with a shrug.
“And?”
“And?”
“You’ve got that soft look on your face. You never have that look on your face!”
Katsuki laughed. “You read me like an open book don’t you?”
Mahoro huffed. “Of course I do.”
Katsuki set the pictures down and folded his hands on the table. Mahoro noticed they were baby pictures of her and Katsuma. If it wasn’t for the dates scrawled on the bottoms of the pictures, she wouldn’t be able to tell the difference.
“What if I told you…you and Katsuma are gonna have a younger sibling?”
Mahoro stared at Katsuki mortified. “You…you got knocked up by my teacher?!”
“Hey! Don’t say it like that! Who taught you that anyway?”
“How am I supposed to go back to school? Everybody is gonna know you slept with my teacher!”
“Not if you don’t tell everybody!”
“First, you make Sensei my dad now you’re gonna have a baby!”
Katsuki rubbed the bridge of his nose. “I thought you’d be excited.”
Mahoro huffed as she grabbed her backpack off the ground. “I am! And I’m happy I have a dad now. It’s just…a lot when I have math homework.” She stomped off to her room. Katsuki watched after her until she closed her door, gently all things considered.
He sighed and patted his still flat stomach. “We’ve got a long way to go, huh little one?”
—-
Katsuki was exhausted. Normally when he picked alphas for children, he chose ones closer to his own size. How could he pick the biggest, most muscular alpha for his mate and father of his third child? He couldn’t see his feet much sooner than he would have liked and he kept eating weird shit. Only green things. Mostly broccoli.
His pregnant belly was so heavy this time around. He was convinced he was having multiples. He dropped onto the couch and rubbed his belly.
Izuku slunk in the front door sheepishly like he always did since Katsuki told him he was pregnant. He’d been yelled at once during a hormonal mood swing and that was enough. Katsuki watched him from his spot on the couch, tapping his fingers on his belly. Izuku set his bag down and toed off his shoes before coming right over. He kneeled in front of Katsuki and kissed his belly before resting his chin on top.
“Kacchan…” Izuku whined, his scent full of soft apology and comfort.
Katsuki tilted his head as he ran a hand through Izuku’s curls. Izuku purred as he ran his hands under Katsuki’s shirt.
“You look so beautiful,” Izuku said, staring up at Katsuki with so much love.
“I’m a whale thanks to you.”
“You’re a beautiful mother, plump with our child. So strong and delicious.”
Katsuki snorted as a blush bloomed over his cheeks. “You just want some don’t you?”
Izuku stood up and lifted Katsuki into his arms. “Only if you’re feeling up to it.”
Katsuki pretended to put some thought into it. “I think I could fit it in the schedule.”
Izuku purred loudly. The sensation made Katsuki’s heart flutter and their child finally settle down. Katsuki nuzzled against Izuku’s scent gland as he was carried to their bedroom.
