Work Text:
Endeavor was used to scandals. But this one took the cake. It was a stupid fucking mistake. A useless one-night stand. The leopard hybrid was fucking angry as the bunny hybrid in front of him showed no fear as she signed away her rights as a mother and dumped him his son. Maybe deep down he hoped this one would have his fire quirk but something told him he wouldn’t. Rei was already expecting his fourth kid—well fifth.
Word had already been leaked to the press. That he could easily ignore. His family? Not so much. Coming home with a car seat and placing it in front of his wife and three young children.
“This is Izuku. Your brother. Treat him as your brother. Rei take over him. His mother dumped him on me and signed away her rights .”
That’s all he said. No more had to be said.
Rei rubbed her hand over her swollen belly before gently pushing back the car seat cover to reveal the new baby. Fuyumi smiled softly as she saw small bunny ears.
“A bunny!” she squealed.
“He has green hair,” Touya comments.
Rei smiles softly as she sees freckles dusting pale cheeks and wide green eyes. A pup that didn’t look like her or Enji. He was perfect.
Fuyumi and Natsuo stood by the crib watching their new baby brothers sleep quietly. Shouto and Izuku. A bunny and a snow leopard. Just months apart. Touya watched his siblings gush over the babies. He couldn’t do that. He needed to train. His father lit this fire inside of him and he needed to prove his worth before any of the two new brats showed any power.
Rei was tired. Raising one newborn was tiring but two? She was exhausted as she breastfed Izuku and pushed the bouncy that held Shouto. She wasn’t too sure what would be different between raising a pup leopard and a bunny. Apparently bunnies require much more attention than her average pup.
Touya continues to be rude to her as she tries to convince him to stop using his quirk. Her boy keeps harming himself trying to make his father proud. She tries to ignore how disappointed Enji was when Fuyumi revealed her quirk. While Touya had fire but his skin could not handle it. Fuyumi had ice but her skin was too warm for it causing her to get frostbite quickly. Natsuo shows signs of just inheriting her ice quirk with no fire.
Turning to her son Shouto she already knows deep in her bones he has both her ice and Enji’s fire. White hair split with crimson, one turquoise eyes like his father’s, and one grey one like her. Izuku, well, with green fluff hair, wide emerald eyes, and freckled cheeks. He was a breath of a fresh air to her.
She smiled softly rubbing fingers over Izuku’s green ears and doing the same over Shouto’s white one. It was times like this when the house was quiet besides the chatter of her children and a soft easiness on her shoulders.
Touya watched as his brothers crawled around the living room. Izuku sucked on his pacifier as Shouto stayed right beside him the whole time. Natsuo and Fuyumi played with them and entertained them as their mother slaves away in the kitchen for dinner.
Touya keeps his distance but can’t help but be drawn into the family room. In the end he stays close and plays with his siblings. It’s nice.
He isn’t burning himself today but tomorrow would be different. When his father gets home he’s in a slightly better mood. He joins them in family room for a bit watching them carefully. His eyes steady on Shouto and Izuku.
It’s peaceful. For now.
“Aren’t you too big to keep doing that?” Touya asked his brother.
Shouto flips him off. So what if he sneaks into his brother’s room because he had a “nightmare”. Sliding the door open he sees his bunny brother scrolling on his tablet.
“Oni-chan,” Shouto said as be pushes off his blankets and tangles himself between his legs.
“Shoucchan,” Izuku says happily and pushes his tablet to the side and hugging his brother.
Shouto curled his tail possessively around his brother’s thigh and purred against his chest. Izuku ran his fingers through his hair and pulled more purrs from his brother.
“Father hasn’t been too harsh on you, has he?” Izuku asked.
“No,” he mumbles, “Since I’ve been opening a bit more to my left side and with your quirk it’s been easier. He doesn’t seem so keen to beat me especially with Touya on his ass everyday.”
“Father eventually gets his way. Are we going to visit Mom tomorrow?” Izuku asked as his alpha brother looked up at him.
“Sure. I don’t like you going out to places without me,” Shouto says making his brother laugh. It’s a soft laugh but it makes his heart clench and butterflies swarm his stomach. He presses nose to his stomach again and purrs softly rubbing his scent over him.
It was only just a couple of months ago he presented as an Alpha. Unfortunately, the same can not be said the same about his older brother Izuku. But he was sure his brother would present as an omega. Even if it was much later his brother was born to be an Omega. Preferably his omega. His brother was perfect. Maybe their relationship was too much for some people. People found them too close for brother’s much more as half siblings.
Touya wasn’t blind.
From when his little brothers were toddlers he noticed how close they were. Now that both go to Shiketsu High they’ve gotten touchy. Of course they come package deal in working together. Izuku’s quirk was pyrokinesis. Although his ability to create fire was hard he very easily manipulated it. Izuku had practically clung to the idea of becoming Shouto’s sidekick or working together as duo. He had the heart of a hero but he also had many ideas he wanted to do. In the end he was placed in the hero course and came in third at the Sports Festival.
Shouto being the youngest of the five had everything he ever wanted. Especially that he had both ice and fire. But his brother was just too possessive of Izuku. Wrapping his tail constantly around his waist or his thigh. Always rubbing Izuku’s bunny ears no matter how many times he complains that there too sensitive. But Izuku is the same. Plopping himself into Shouto’s lap when they think their alone. Shouto might be the youngest but he was taller than Izuku. He occasionally catches them staring at each other for too long. And their codependency drove him insane sometimes. It was too much! Even as toddlers. If Izuku was gone for a doctor's visit that Shouto had no business being at he would throw the biggest tantrum. He definitely drove their father up the walls with his wails of being separated from Izuku.
Now Izuku clung to him like velcro. When they were five and Endeavor had begun Shouto's training, Izuku bursted in. Yelling and screaming to the older alpha to stop hurting his brother. Now as teens if separated Izuku falls into depression and Shouto is much more aggressive.
But he’s sure it’s just brotherly love. They were always closer than any of their siblings.
He just hoped he was jumping to conclusions.
Enji was not blind.
He might be a shit father but he was not blind and certainly not deaf.
He’s quiet as he can be as he reaches Izuku’s room. He wants to think he’s imagining the noises he thought he heard earlier. The door is cracked open allowing a sliver of space for him to watch his son. He sees it then. Shouto pinning his elder brother to the futon and kissing him slowly. Izuku wraps his legs around his brother’s waist.
Enji stays still as he watches Shouto slide a hand between them. “Shoucchan,” Izuku whines as Shouto slides his hand beneath his shorts. Izuku had just recently presented as an omega and Enji had not been careful in protecting his son from alphas. Well, from the strange ones, yes, but he never considered the alphas in his family.
His feet couldn’t move. Frozen in place in front of the door watching his most beautiful creation create a disaster. Shouto licks and sucks on his brother’s scent gland. Izuku flushes, beyond embarrassed at the amount of slick coating on his brother’s fingers. He feels liquid fire fill his veins as Shouto continues his ministration, flicking his thumb occasionally over his swollen clit. His thick scent of cinnamon lays on them both like a blanket.
He feels his brother’s fangs nick his skin.
“Shoucchan no marks! I can’t have Camie asking questions,” the bunny hybrid whines as his brother completely ignores his complaints and continues with leaving marks.
Shouto has always been too possessive.
Scaring any alpha, beta, or omega who dared try and court his omega. He won’t forget the stupid blond boy from Yuuei. He practically wanted to knot his brother in front of him with how forward he was. The blond wasn’t who Izuku looked for anyways in a mate. He was too brash, too loud, too much.
Izuku in his own ways was just as possessive.
Boy omegas were rare enough and were often treated with a higher respect than the girls. But equally female alphas were held on a higher ground than regular male alphas. He’d always pushed his brother away from girls and boys who wanted a quick fuck or his number. A girl cat hybrid once gave him box of chocolates to give to Shouto for Valentine’s Day. Shouto never received those chocolates.
“Kiss me, please!” Izuku nearly screamed as his orgasm was on the crest. Shouto quickly smashed his lips to his brother fingering him through his orgasm. Slick pooled beneath Izuku as he body gently relaxed from the intensity.
Enji finally felt his legs move. He was oddly quiet as he shut his room door. He watched his two sons engage sexually with each other and his dick was harder than it ever was. No! This was wrong beyond what he ever thought his sons would ever do.
Rei smiles softly as her son tells her the story of his current work study with a hero named Eraserhead. Shouto lays on her bed with his head in her lap and his tail wrapped around Izuku. She misses them dearly.
Running her fingers over Shouto’s red hair carefully rubbing the tip of her fingers over his ears. A small chuff left his throat as his tail tugged Izuku to lie down beside him. She chuckles softly as she plays with both of their hair. She notices Shouto hug Izuku tighter and bury his face into his scent gland. It was highly inappropriate to show such affection in public let alone to your brother.
But Izuku didn’t complain. She brushed it off.
Just brotherly love.
Izuku had his nest perfectly made—a mixture of all his family with just a tad more of Shocchan. His father was working late, Touya had some business deal, Natsuo was at a frat party, and Fuyumi was away on a trip to Paris. Just him and his little brother Shouto.
He had a study session but it was canceled. Shouto was fresh out of the shower after a workout in the dojo. It was rare for him to use it without their father being there to monitor him. Shouto slides into his nest being careful not mess anything up as Izuku meets him for a soft kiss.
“You okay?” He softly asked.
“Better now,” Shouto replied leaning down to capture his plump lips again.
A pink blush covers his freckled cheeks as he pulls away and cards his fingers through his brother’s silky hair. “Are… will you knot me today?” He shyly asked his cheeks turning redder.
“Should I?” Shouto teases as he pushes Izuku to lie down. Pulling his T-shirt up and revealing the lacy purple panties.
“You’re being mean, Shoucchan. I won’t let you come in here anymore,” Izuku shoots back. He holds back his smirk at the growl his brother lets out.
“I dare you oni-chan… you belong to me. Anyone else you bring home I’ll find a way to ruin it,” Shouto responded as his fire slowly burned off his panties. He could easily get him new pairs.
“Oh yeah? And how would you do that?” Izuku pressed on hating how much slick was pouring from his cunt. Little burn marks forming around his hips. He hopes for a couple of handprints too if Shouto truly wants to.
“The cameras in your room,” he suddenly said.
The bunny hybrid stills. “Cameras?”
“Its only if you leave me, oni-chan,” Shouto replied kissing his cheek softly. “I can show the footage later.”
A full body shiver leaves Izuku at the thought. When or where Shouto found the time to even set them up to just keep an eye on him. He liked it. Knowing Shouto was always watching.
“Come on and fuck me already, brat,” Izuku tugged his pants off. Shouto was never one to disappoint.
Sliding his cock between slicked, sticky fat folds Shouto could cum on the spot. Izuku softly whines and grinds back against him as his clit kisses the crown of his brother’s cock. Shouto is careful in not to hurting his omega but his brother is impatient. Izuku nudges his heel into his brother’s backside forcing him in. It’s a wet smooth slide in. Shouto moans into his brother’s ear as his walls clench around him and honey slick stains his happy trail.
Izuku feels tears spill over as Shouto settles deep inside. He sighs at the feeling of his brother settled against his cervix. It felt like a wound finally stitched up. Being tied beyond just the blood they share between them.
Shouto runs his fangs over one of Izuku’s bunny ears making his brother clench tightly and whine loudly. He was incredibly glad no one was home. He started to pick up pace giving his elder brother a thorough fucking.
“Yes! Yes, yes, don’t stop!” The omega whines as his insides are rearranged to be molded around his brother’s cock.
Shouto feels his fangs enlarge and his gums burn with built-up venom. Izuku feels a slight burn on his thigh. He looks down seeing Shouto had either intentionally or accidentally burn him. A red handprint marked against his pale thigh. Deep down he knew he was a masochist. Inflicted by the right person and more slick made a mess on their thighs.
Shoving his knot Shouto is blinded by pleasure and the need to claim and breed his brother. Biting his brother’s mating gland Izuku screams in pleasure.
Izuku felt a nice buzz over his body and his omega was sated. Knotted, claimed, and bred. What more could he ask for?
Natsuo stared at Touya with visceral disgust on his face. They heard enough but Touya just had to watch and make sure he wasn’t going crazy. He doesn’t miss Shouto’s angry glare at him. Izuku is half asleep in his arms, full of cum, and stuck on a knot.
Turning away to Natsuo he’s not sure what comes next. Besides a very long therapy session.
