Chapter Five - Legacy

.

.

.

When Katsuki came to it was to the sound of a dull beeping monitor. He blinked open his eyes slowly and the blinding white hospital lights made his head hurt like he had just gotten fucking rammed by a truck.

Where the fuck am I? He hissed to himself when he tried to move and a sharp pain starting in his left side shot all across his body. The intense warm pressure and difficulty breathing quickly reminded him of what happened.

That dirty fighting bastard Chizome happened.

He nearly growled thinking about the match. Izuku warned him that the other fighter fought dirty, but he wasn't expecting him to grab his hair like some goddamn punk. Then he fully wasn't expecting for Chizome to purposefully break his rib.

He remembered the struggle of not being able to use his dominant side as he was too busy defending it from further injury, but those attempts quickly went out the window as the other man gave him the fight of his life.

Literally. For his goddamn life, apparently.

Katsuki could barely remember the latter half of the match. The last thing he remembered was being pinned in the final round and a voice whispering something in his ear that made him absolutely lose it.

"I'll be sure to fuck him raw until he's bleeding because of you," the deep voice had hissed against the shell of his ear. "I'll break him until he's nothing but an empty shell and there's nothing you can do about it. You'll be just a distant a memory he cries out for when I finish teaching him his place—which is under me."

The visual filled his thoughts and his mind was cruel. He imagined Izuku giving him another sweet kiss and then being abruptly torn out of his arms. All Katsuki could see was Izuku screaming, crying, and reaching out toward him as Chizome dragged him back to Nikko.

His vision went blood red from there.

The next thing Katsuki remembered was Izuku's tear filled face.

"Kacchan, please look at me," the soft voice had whispered, pulling him out of his haze. He remembered frantically checking Izuku up and down for injuries, making sure that goddamn bastard didn't touch him—then he remembered green eyes looking horrified and everything fading to black.

Ah, that's what happened.

The blond groaned as he finally glanced around the bright, white room. He could see that he was in fact in a hospital with a needle in his arm. Dusk red eyes glanced around at all the objects in the space until his sights fell onto the small body curled up asleep in the plush blue chair next to him.

All of his senses immediately heightened, and adrenaline pumped through his body at the sight of the omega sleeping so peacefully at his side. The gentle morning sun graced Izuku's skin making him look like an angel of sorts and it pulled on his heart greatly.

Red eyes softened at the sight of the gentle freckles and closed eyes that translated calmness, but more importantly, it signaled safety.

Izuku was safe. Safe right next to him.

His chest rumbled in satisfaction at the thought. Thank fuck everything was settled.

The low rumbling sound filled the room and slowly Izuku's eyes fluttered open at feeling of those vibrations. Red eyes met green and a smirk bloomed on Katsuki's bandaged face.

"Hey there, nerd," he said through a hoarse voice. "Told you I would make it back in one piece—give or take, I guess."

Within the second, tears started to swarm the emerald irises.

"Kacchan," Izuku's strained voice whispered and the omega got up to hug him.

Warm arms embraced Katsuki and soft green curls tickled his chin as Izuku buried his face into his neck. He could feel their scents mix together and his body relaxed at the sweet cinnamon smell that flooded his senses.

"I'm so happy you're okay," Izuku said through a small sob, arms tightening around him. "Thank you so much, Kacchan. I don't know how I can ever repay you or tell you how much everything you did means to me. I-I was so scared you wouldn't wake up and then how that would be terrible—"

"—Slow down, freckles. You're making it sound like I died," Katsuki laughed lightly. The injured alpha smiled as he held the other in his arms and rubbed Izuku's lightly heaving back with care. "You should know I'm way too fucking stubborn to just be taken out like that."

Izuku let out a shaky laugh at the comment and leaned back to look down at the alpha. Katsuki felt himself stiffen at the sight of happy tears, but Izuku in his arms felt nice. He returned the smile Izuku gave him before letting out a sigh. Dusk red eyes glanced down at his once uninjured body and groaned.

"But I guess the bastard did still do a number on me, huh?" He muttered feeling annoyed at how fucking dirty the fight had been.

Izuku gave him a guilty look. The blond wanted to wipe that expression off the greenette's face because he could practically hear the gears turning in that big ass brain of Izuku's. It didn't take a genius to know the omega was probably beating himself up over Katsuki getting injured.

"The doctors explained that it was a punctured lung," Izuku whispered, not looking at him. "They said it was good there was help ready on site and they were able to treat you immediately…but it's still going to take about four months to heal. You won't be able to fight for a while."

Katsuki watched as Izuku made a pained face and continued speaking.

"I-I'm so sorry I put you in danger for me, Katsuki. Now you can't fight for a while all because of the fact I couldn't fight himself myself—"

"—Cram it, Deku," Katsuki interjected quickly. He sat up slightly and winced when a sharp pain sparked over on his side. Izuku's eyes widened as he tried to steady the other from hurting himself, but Katsuki just shooed him away, forcing him to lean back a bit. "I'm fine—it's fine, just trust me. Ain't your fault, not by a long shot."

Izuku's eyebrows wrinkled with deep concern as he looked the injured alpha up and down.

"B-But your fighting career—"

"—Will be fine," Katsuki sighed. "It'll resume once I get out of this hospital bed and I'll go back to kicking ass."

He gave a wide signature cocky grin and Izuku smiled back weakly. Katsuki saw the small grin and his own smirk spread wider. The blond shifted in the bed and scooted over on the narrow mattress and patted the empty space.

"Now, get up here with me, freckles," he rasped out giving a smirk. "I think I remember seeing somewhere that cuddles or some shit make broken bones heal faster?"

Izuku immediately started laughing. The alpha could feel his heart tightened at the light melodic sound of Izuku's soft voice. He always sounded so fucking sweet and it did terrible things to him

"Kacchan, that's not a thing," Izuku smiled at him knowingly but then tilted his head, green eyes full of admiration and care. "But...I guess it wouldn't hurt. I think we have to explore it further, ah...just to be sure. See how great cuddles can heal."

"Sounds like a plan to me." Katsuki grinned like he was the king of the world as Izuku got into the hospital bed with him.

The plush surface of the mattress dipped underneath Izuku's weight and the smaller male leaned into his side amorously. The close scent of honey and cinnamon enveloped all of Katsuki's senses as he sunk further into Izuku.

A rose-tinted blush sprinkled across both of their creeks as they shyly leaned into each other. Katsuki wrapped a strong arm around Izuku's waist, pulling him in closer, and Izuku laid down and rested his head against Katsuki's shoulder.

This is perfect.

. . .

The rest of the morning consisted of Toshinori, Kirishima, and other various fighters coming in to see him in the hospital. They all were ecstatic to learn he had finally woken up and Kirishima did his annoying ass best friend thing of nearly crying.

But Katsuki didn't mind deep down. He was happy he was okay, too. Toshinori and the doctors spoke with him about his recovery timeline and it took everything in the blond not to groan out loud—or go find Chizome and finish off the fucking job.

The doctors told him he was lucky that it was only a broken rib and a punctured lung and not something that would've taken him out permanently. They told him he could go back to coaching Izuku in a month, but no sooner.

Katsuki gave a reluctant, yet thankful smile, but he could feel Izuku's hand tighten in his at the news.

The greenette was listening closely to everything the man in the white coat was saying, nervously toying with the sheets on the hospital bed. Katsuki gave a reassuring squeeze back to the omega's hand to help him calm down.

Just when that seemed to be the trick, another body had stormed the hospital room.

"I got the phone call and rushed right over when I heard the news," the commanding alpha voice said. "You goddamn knot-head, you always find yourself in some trouble." The blonde woman stood proudly in the hospital room as she signed off on all the needed paperwork to discharge him as her son's emergency contact.

Katsuki nearly fucking groaned.

His mom was always a hurricane wherever she went, but she cared.

Just...aggressively. Aggressively cared. It's exactly where Katsuki got that fierce protective side of him from.

His mom and Toshinori exchanged updates and kind conversation as he got dressed in normal clothing and prepared to head out.

The doctors had informed him that he needed to go get adequate rest and his mom volunteered for the job. She informed everyone that she was going to take Katsuki home, back to the far side of Tokyo, and immediately Izuku asked to come with to help.

His mom made a small joke about how, while she was 'eager for grandkids,' she didn't want Izuku to forfeit his matches that were already lined up. Blushes spread over both young adult fighters in question and Toshinori agreed with a small smile.

"Mrs. Bakugou is right, Izuku," Toshinori said to them both. "It's just a month, then Katsuki can go back to living at his loft. You'll get to see him when he's a little better. Until then, I'll coach you and make sure you stay on track."

Izuku nodded in understanding, putting on a tightlipped smile the entire time.

As they were about to leave, Katsuki felt his alpha nearly fucking whine at the prospect of being away from the omega. But it was fine. Just a month. He could do that after the shit show he just went through.

He watched as Izuku carefully looked him up and down, as if trying to memorize the moment. But seeing those big, doe like spring eyes locked on to him made Katsuki's stomach fill with something close to butterflies—something he would never dare say out loud.

When he thought no one else was looking, the blond quickly leaned down to steal the kiss he had been thinking about for way longer than he'll admit to.

"See you in a month, freckles," he whispered against those rosy lips and Izuku leaned in for one more kiss. Green eyes were close to tears, but they were happy tears.

"See you in a month, Kacchan. Come back to me soon."

. . .

The month went by longer than he ever anticipated. He wasn't expecting to feel so goddamn antsy not being able to fight. He had to watch everyone at Plus Ultra gym's matches from home via his parents' tiny ass television.

The young, successful alpha had bought his parents a new flat screen a while ago, but they never used it. Insisted on it being too advanced for them or whatever. So Katsuki sat cuddled up on the couch pretty much for thirty days straight, watching intensely at how amazing all his gym mates were.

He would flood Kirishima's phone with aggressive text messages whenever he saw some sort of slip up from the famous 'Red Riot'.

[You]: What the hell was that?! I thought I told you to try that combo we worked on!

[Shitty Hair]: Aren't you supposed to be relaxing and minding your business? No couch-coaching! :(

Katsuki ignored the back sass and did the same thing for everyone else: Todoroki, Denki, and even Sero. He got back pretty much the same responses, but he didn't give a shit. His friends needed to be on their A-game while he was away. Plus Ultra Gyms went beyond, not half-assed shit.

However, there was one person he didn't have to couch-coach for and it made his heart fucking swoon. The blond watched Izuku like he was hypnotized as the omega took down alpha after alpha like it was fucking nothing.

An inspiring smile spread across the greenette's face as he proudly wore signature black and orange Ground Zero colored muscle tanks and—Kami have mercy on his fucking soul—tiny ass orange shorts.

His alpha was beyond satisfied with the sight.

It was even more satisfied when Izuku would send after match selfies of him smiling into the camera with a peace sign and a cute 'can't wait to see you!' texts attached. The greenette was so goddamn cute, and the look of happiness written plainly acr oss his freckled smile. The dimples showing in Izuku's round cheeks made the pain in his chest more than worth it.

They texted and called every day and he started to learn a lot about Izuku that way. How he was raised, trained, even how he was supposed to come to Plus Ultra gyms originally. After hearing that fact, Katsuki was sure that him and Izuku were destined to meet. One way or another.

Everything about Izuku was amazing and he was the sweetest goddamn person on this planet. Not a soul could tell him otherwise.

But with Katsuki being Katsuki, it didn't take long for him to coax that sexy fucking omega into giving him more incentives toward a speedy recovery. He somehow convinced Izuku to send him some very encouraging selfies in the mirrors at the gym when he was solo training at night.

Tiny orange shorts bunched up around muscular thighs with legs widespread for the camera, giving a full view of that round, perfect ass and Izuku's strained hard-on. The greenette's work out shirts would be always pulled up, giving view of a shy pink colored nipples that Katsuki just wanted to sink his teeth into and give several generous licks. Glossy emerald eyes were always glazed over with lust and need.

Katsuki didn't need to be there to know Izuku probably smelled sweet like fucking fruit, ripe for the picking, and the alpha was more than happy to be the one to be to take a taste.

Ever since learning that Izuku used his shirt for his heat, visions of that perfect man spread across his thoughts. All Katsuki could imagine was Izuku keening for him while dripping wet with a flushed face. He could particularly smell that addictive honey perfume as his mind filled in the blanks of Izuku screaming out 'Kacchan!' as he came over and over.

Now Katsuki wanted nothing more than to deeply satisfy the omega like he deserved.

Izuku was beautiful. Strong, gorgeous, and he took Katsuki's shirt to help through his heat. That cleared up the air about Izuku possibly being interested in him. Then even more so when they drove home the concept with a kiss. Then another, and another.

The sweetest kisses Katsuki has ever been given.

A small smile spread across his face at the thought.

He couldn't wait to go back.

. . .

"Call us when you're all settled in!" His dad called from the car as Katsuki got out. "Are you sure you don't want us to drop you off at your apartment?" His parents gave him confused looks but Katsuki waved them off.

"I'm sure," he responded with a low rasp in his voice. "Kirishima's dumbass said something about meeting at the gym first thing in the morning. Something about meeting to figure out my fight schedule since it's all fucked up now."

His parents blew their kisses goodbye and Katsuki begrudgingly returned them, seeing as it was something they always did, despite being told to stop for the past several years. The red car drove away, leaving Katsuki with his bags in front of the large doors of the gym he'd come to know as home.

However, when he walked in, the entire gym floor was dark. He frowned wondering why none of the lights were on until he took a step further in and almost had a damn near heart attack.

"Surprise!" A loud chorus of people shouted at him. The lights flashed on in a second and the smells of everyone in his gym-pack mixed together to create a warm, welcoming environment.

Red eyes blinked in surprise at the large banner that read 'Welcome Home Ground Zero!'. It was decorated in his colors and there was a table full of food and drinks. Loud music blasted into the air and the atmosphere of his usual work out spot suddenly felt more like a party house.

"What the hell—" Katsuki started but before he could even get the words out, he was rushed by a blur of green nearly tackling him down to the ground. He stumbled and out of reflex, dropping his bags and wrapped his arms around the warm body that willfully collided with him.

"Welcome back, hero," a gentle voice whispered into his chest. Katsuki hugged the smaller male tighter when he realized it was Izuku. The omega pulled back to look up at him with forest colored eyes holding a thousand stars.

Fuck. He was so perfect Katsuki could just lean down again and—

"—Hey, love birds, no PDA while we're all waiting to cut the cake!" Kirishima yelled out, giving a shit eating grin as he and several others walked up the pair. "I crouched in the dark for thirty minutes for this, I'm eager to get to the food!"

"Oi, no one asked you to fuckin' crouch in the dark in the dark for me," Katsuki snapped back automatically with no real bite to his words.

"Actually, Midoriya did ask us to crouch in the dark, as an FYI," Todoroki cut in with a laugh, giving a blushing Izuku a knowing smirk. "This whole party was his idea. I think out of everyone he was the most eager for you to come back."

"Yeah, I know I sure wasn't stoked for it," Sero joked giving Katsuki a gentle poke to his cheek. "Gotta go back to smelling that musty 'lucky' shirt of yours whenever you're at the gym, but I'm sure Izuku is all about it."

The omega's face turned a bright shade of red as he stepped back from the alpha, with a graceful smile. Everyone gave heartfelt laughs and continued to give Katsuki hugs and ask how he was doing, but the earlier information was still sinking into the blond alpha's head.

Red eyes glanced down at bright green and he tilted his head curiously at Izuku. The omega wasn't looking at him, too busy being embarrassed by the admission.

Everyone continued to chat amongst themselves until they all began chatting at the party, blending into the background and heading towards the food. Katsuki bent at the waist and flirtatiously leaned into Izuku's space.

"You really missed me that much, huh, nerd?" Katsuki teased with a cocky smirk, but his heart was tripling into overtime. He could smell Izuku's natural scent sweeten at the close distance and a subtle sugar-coated blush coated his freckles in a delicate manner.

"I did," Izuku said firmly but still so soft. He returned a mirthful smirk and playfully punched Katsuki's shoulder. "Don't let it go to your over inflated ego though. Now, let's go get some cake."

The greenette offered him a million-dollar smile while taking his hand and leading him towards the rest of the bustling party.

While looking at their joint hands, Katsuki realized that he would follow anywhere Izuku would lead him.

. . .

The party continued on with everyone laughing, joking, and telling Izuku that he did a great job putting it all together. The greenette would just fumble over his words at the compliments as he nervously poked the orange and white cake he had apparently made.

Katsuki didn't know how to describe in words how he felt when it sunk in that not only had Izuku put together the party, but he had made the cake and snacks as well. The nerd was fucking multi-talented and the whole gesture showed how much he cared about Katsuki.

The tall blond didn't dare let go of the smaller male's hand the entire time and Izuku happily stayed by his side. The pair both watched as Denki and Kirishima started to playfully tousle between each other. A crowd immediately started to gather around, and it was then that Toshinori walked up to them and asked to borrow Izuku for a moment.

When the greenette came back, there were tears clinging to the edges of his eyes, but his smile was the largest Katsuki had ever seen it. The greenette's mood was elevated tenfold and it made Katsuki curious.

"You look happy," Katsuki said with a curious stare. "What's got you in such a smiley mood?"

"Besides you?" Izuku replied, chuckling slightly. The alpha shrugged with a smile as he watched the omega wipe the small tears away and continue speaking. "Everything's coming together after so long, that's all. Toshinori just told me he finally got in contact with the woman who trained me, Nana."

"The badass you were telling me about over the phone, right? Is she gonna come here?"

"Yeah!" Izuku beamed and the blond's heart clutched. "He told me she bought a train ticket this morning. She actually reached out for Toshinori when she saw the news about Chizome and the honor match but Toshinori wanted to wait and surprise me with it since I was still so stressed out about you coming back."

Izuku let out a happy laugh and Katsuki reached to grab his hand.

"'Zuku, that's great," the alpha's voice rasped out, staring in awe at the man in front of him. "You deserve everything that's coming your way, I hope you know that. I wouldn't have fought for it if that wasn't true."

"Well, I wouldn't be getting any of this if it wasn't for you, hero." Jade colored eyes looked up at him tenderly and Katsuki couldn't stop his own smile from spreading if he wanted to.

"Hero?" Katsuki chuckled. "Another nickname for me, freckles?"

"Not a nickname, I'm just stating a fact. You are my hero, Kacchan."

A deep rumble of approval bubbled in the alpha's chest when the omega reached up to pull him down by his shirt and gave him a long-awaited, deep kiss.

. . .

Another three months went by with Katsuki training Izuku fiercely and taking it as easy as Bakugou Katsuki could. All his gym mates would have near heart attacks when the blond would try to coax someone into sparring with him, but everyone turned it down saying they wanted to beat him when he was in 'top shape.'

At first it bothered the alpha, but Izuku quickly made the new down time more than interesting. The pair started dating openly and the headlines began to refer to them as 'The Wonder Duo.' After all, Izuku was quickly climbing in the ranks faster than any other MMA fighter in Japan and Katsuki was the first alpha in decades to win an honor match—with a broken rib on top of it.

Chizome went back to Nikko and was never heard from again, but Katsuki could tell he was probably bitterly watching Izuku flourish like the rare flower he was.

The three months they dated were the happiest Katsuki had been in a long time, and he realized he had found a new reason to be excited about life. Izuku helped him through his recovery and frequently came over to the apartment to cook, clean, watch movies, and sometimes they would slip into heated make out sessions.

It was very frequent that Katsuki would pin Izuku against his kitchen counter or Izuku would climb into his lap during movies. Didn't take long for either of those scenarios to end with Katsuki dry bucking frantically into a moaning Izuku as they kissed desperately.

The greenette always drew a line with how far it would go, but Katsuki didn't care. He'd do a fucking backflip on cue if Izuku asked him to. Their scents were blending together wildly, and the alpha decided that Izuku showing up to the gym smelling like a mix of honey and caramel was fucking fantastic.

The freckled man would always tease him about being ready to for their rematch when he finished recovering. As a reply Katsuki would just give a greedy grin and say that the omega was no one near ready for it.

Which is why when the doctor gave him the okay to begin fighting again, the pair kept flashing each other knowing smiles and grins all day at the gym. The flirtatious look in the omega's sparkling green eyes as they did their morning sparring made excitement swell in Katsuki's stomach.

He was beyond itching to get his second shot at fighting the powerful curly haired man again. The alpha could feel his pheromones spike in and out of control as the day went on, even Kirishima pointed it out several times, but he couldn't help it. The smell of excitement and eagerness filled the gym until it was almost suffocating.

When the last person in the gym left and it was just Izuku and Katsuki left in the gym going over some new combos, Katsuki could particularly feel the tension between them rise.

The omega flashed him a competitive look before curling his finger in a 'come hither' motion. "Ready to get your ass kicked a second time, Kacchan?"

The alpha in question gave a feral grin as he started wrapping up his hands, following the greenette into the ring.

"I dunno about that this time, nerd. I've gotten faster and stronger since the last time we went up against each other," he said with a handsome grin. "Had a certain match to train for and make sure I was the best in the ring."

"I got stronger too," Izuku laughed, running his hand through his thick curls. "I've been being coached by this guy for the last year almost. He's really talented."

"Oh, really? I bet he's really fuckin' sexy too, must've been hard to focus on what he was trying to say," Katsuki teased and Izuku rolled his eyes but didn't deny it. "Alright, let's get started and put these new skills to the test. Best out of five pins, short stack."

"Sounds good to me. Count us in, Hero."

An expression close to hunger flashed across the omega's face and Katsuki never felt more excited to brawl with someone. This was the type of fight he was always reeling to have ever since he started fighting.

They backtracked to their respective corners of the ring. The alpha rolled his shoulders and watched as the omega stretch out his arms. Viridian eyes were blown to nearly all black and if Katsuki could feel his own eyes dilate.

"Three," Katsuki began and he saw Izuku lick his rosy lips. "Two," he could sense the smell of honey and cinnamon getting stronger, "One—go."

And with that lightning speed he helped Izuku hone, the greenette charged first.

The alpha grinned like a mad man when the first kick was thrown. He ducked and grabbed the smaller man's leg by his slim ankle, surprising the other. Green eyes widened when the alpha forcefully spun him around and then and harshly knocked the back of standing leg, forcing the omega to buckle all the way down on the ground.

The greenette let out a slight yelp as they went toppling onto the soft plush surface of the mat and the large body above him immediately moved to pin him. Katsuki's large hand found its way onto his back. The alpha pressed down hard as he tried to get the omega pinned, but Izuku wrestled his way out.

With strength the alpha forgot the small male had, Izuku snapped himself up on his knees and lifted up Katsuki to body slammed him backwards. The blond growled fiercely, dominating pheromones releasing unwillingly into the air when his head hit the back of the mat.

A thick, smoky aroma filled the air and, while it should have made Izuku feel the need to submit, it only egged on his own excitement. The omega whirled around, flipping himself to try to pin the large figure but Katsuki grabbed his waist and threw him on his back again, wedging himself snuggly between the thick legs.

An unexpected, challenging rumble echoed out from Izuku's chest as the greenette dodge Katsuki's effort after effort. until searing pressure began to build within both of them.

The blond tried to ignore the coil of need that was wrapping tightly in his abdomen as he heard the omega whine and hiss. They tossed around, going back and forth with who was on top until Katsuki grinded down harshly between Izuku's legs, making the other moan.

The most delicious sound the alpha had ever heard escaped Izuku's pink lips and suddenly Katsuki wasn't too sure if they'd blurred a line.

The strong legs wrapped around Katsuki's waist tightened, locking him in place as he gave several more needy bucks, and Izuku began to meet him with the rhythm. A loud growl ripped from Katsuki's throat as he forced the omega to stay down when two hands reached out to grab him by his shirt, bringing their foreheads to rest against each other.

Katsuki stopped moving, listening only to the heavy breathing in the room as they stared intensely into each other's eyes—and that's when he smelled it: sweet and warm was the unmistakable scent of Izuku's mating pheromones for the first time.

Katsuki's chest vibrated at the realization.

The grip his large hands had on Izuku's small waist tightened dangerously and he gave another warning growl when the omega began to rock steadily into his growing hard-on.

"Izuku, your scent," he said, voice laced with caution as he tried his best not to let his mind get too clouded, but it felt impossible. "Fuck. You smell so damn good."

"Y-You do too," Izuku shakily breathed out, hot breath tickling his face. The omega continued to devilishly grind on him, firmly pressing their clothed erections together, and gripping his shirt tighter.

Katsuki felt screwed as he was enveloped with the honey-like cinnamon aroma and Izuku's hands slowly made their way into his messy spikes. He was entangled in Izuku and he knew damn well he wasn't getting out any time soon.

The tight coil in Katsuki's stomach became almost painful when he could feel the space where he was pressed firmly between Izuku's legs grow slightly damp the longer they softly moved against each other. Soft whines and gasps spilled from Izuku's beautiful mouth as the omega clung to him, calloused hands holding on desperately to his shoulders.

Then the distinct smell of slick breached his nose and he gave a harsher grind as he pulled Izuku flush against him. He buried his face in the crook of Izuku's neck, drinking in the intoxicating smell emitting from the omega's scent glands.

"You're really fucking wet, 'Zuku," he rasped out in a deep voice, his inner alpha was clawing at his chest and his breathing quickened. "Your scent is telling me you want this...do you want me? I can stop if you don't."

Katsuki's own scent quickly switched, its dominating burnt caramel smell filled the air but this time it was mixed with clear arousal. He needed to know if Izuku wanted him. He needed to know if he was enough for the strong, powerful omega underneath him.

The alpha pulled back to look down at the other as he waited anxiously for a response. Red eyes watched as a shy expression encased the omega's face. Bright eyes glanced up from underneath long, black lashes as if Izuku was deep in thought.

Slowly, like a daydream Katsuki only could imagine, the omega closed his eyes and gradually tilted his head to the side, showcasing the unmarked, beautifully pale neck to the alpha.

Katsuki snapped.

"Shit," the deep voice hissed as he leaned forward and grabbed Izuku's face with both of his hands, bringing him into a soul drowning kiss.

The greenette keened headily into their joint mouths and they were both washed under by the tide of beautiful bliss. Katsuki groaned with he felt Izuku work his mouth hungrily against him like he was was trying to devour the alpha. Too far gone, the alpha bit back with just as much neediness, sucking Izuku's bottom lip into his mouth and giving a harsh bite.

"F-Fuck! Kacchan, please," the omega panted. "I need you." He lifted his hips desperately to press into the larger body above him, grinding their socks directly together. Izuku's voice broke into a high-pitched moan as he rocked into the muscular body above him.

Without further question, Katsuki reeled back quickly and began to strip himself of his lucky shirt, tossing it off to the side. Izuku quickly followed suit, ridding himself of the 'ground zero' short crop top he was wearing.

Before the omega could even began to touch the orange shorts he was wearing, the alpha let out a harsh growl. Katsuki's nostrils flared as he reached down and pulled the shorts to the side without removing them and exposed the slick covered skin.

"K-Kacchan!" Izuku yelled out surprised when the alpha dipped his head down and expertly manhandled him.

The strong blond grabbed his ankle and bent one of his legs at its knee to his chest. Izuku let out a shaky moan and threw his head back when Katsuki's tongue darted out, licking his sensitive area.

"You taste so fucking sweet," Katsuki moaned as he tastes buds exploded with the sucrose taste that was purely Izuku. "Just like I imagined, so goddamn addictive."

Izuku groaned and buried his hands in the blond locks between his legs. The omega's legs started to shake as Katsuki used his one arm to bend Izuku in half, giving the alpha more access to his omega's dripping hole. The rough tongue swirled and prodded his twitching entrance, pushing in ever so slightly and teasing him as he pushed his face into the hole of the shorts, he was stretching out the orange fabric.

Pleasure ran all over Izuku's body when he heard the low sounds of Katsuki's growling get louder and louder until the sound of fabric ripping echoed out.

Green eyes shot open at the new feeling of exposure. He looked down at his now ruined shorts and his alpha didn't come up for air; he just pressed his face in further into his slick covered backside.

"That's more like it," Katsuki chuckled with a hungry expression. "You're so gorgeous like this omega."

Izuku whined loudly and bit his lip when he felt two fingers push into his wet entrance with purpose. The digits curled automatically to press into his pleasure button that was deep inside of him, and he arched off the matt.

"K-Katsuki!" He called out as the large fingers inside of him started to pound ruthlessly. "F-Fuck!" Red eyes locked on him and watched the way his breathing quickened and noted how his toes curled with each pulse against his prostate.

"So goddamn responsive too," Katsuki hissed as he pressed his fingers in harder, not letting up from his pace when Izuku's eyes rolled back. "Bet you can take a me fucking you real hard, can't you?" he asked, eyes clouded with lust. "You take a hit like a champ in the ring. I bet you would take my cock and knot so perfectly too. Right, 'Zuku? You're so goddamn strong."

Izuku's breathing became erratic at the thought and he nodded his head desperately. The praise shot an electric feeling all the way down his spine and his body started to quiver desperately.

"Yes," he breathed out between moans, legs shaking as euphoria washed over all his limbs. "I can take it!" Izuku's green eyes studied the impossibly large bulge in Katsuki's black fighter shorts and groaned at the thought of being filled with the thick cock he had spent the last five years fantasizing about.

The alpha above him gave a greedy grin as he lurched forward, fingers knuckle deep inside of Izuku. The greenette's breath hitched as the larger body leaned over him and began to suck gently on his erect rosy nipples.

"H-Hng!" Izuku cried out as Katsuki's wet tongue lapped, sucked, and stimulated the sensitive skin. Izuku's body jerked with each flick of the alpha's wet appendage on his chest, high pitched moans echoing all over as he was pulled to the edge with the fingers stimulating his sweet spot.

Izuku bit his lip hard enough to taste iron when he realized he was already so close and the next thing coming was going to be better than the thick fingers lodged so deeply inside of him.

The blond felt drunk on the sounds and scent of Izuku as he tried his best to give the omega all the pleasures in the world. He could still taste the saccharine taste of Izuku's slick in his mouth as he worked his tongue to the next pink bud on the small chest.

When he felt Izuku open up even more for him, the omega's hands pulled harshly on his hair, trying to get him to come up. Red eyes snapped to look at Izuku's face and what he saw was the most erotic vision Katsuki had ever seen.

The greenette's face was fucked out, pink blush spilling over from his round cheeks down to his neck and freckled shoulders. The omega's chest was rising and falling heavily, and a needy keen could be heard.

"I need you inside me, Kacchan," Izuku pleaded, spreading his legs wider to emphasize his point. "Please. I need you so much. I've been thinking about this for so long."

"Oh, yeah?" Katsuki smiled handsomely as he started to move his finger slower, more sensually. He drew out several more moans out of the omega before leaning upwards to brush their noses together. "How long as you imagined me stretching you out, 'Zuku?" He asked in a husky voice, several octaves deeper than his usual.

"Since you started your career," Izuku replied back full of lust and love. The alpha's ministrations stopped at the admission and red eyes widened. The omega noticed the pause and the shocked look from the alpha and felt himself grow nervous and continued to explain. "I-I watched you every day…I-I thought of you during my heats."

"...You've been thinking about me for five years?" Katsuki whispered in disbelief. Izuku nodded his head, unsure, and blushed deeper. A bright grin spread across the blond's face.

"Fuck—you're perfect," Katsuki admitted. Izuku looked confused briefly before Katsuki leaned forward and gave him an endearing kiss. When the alpha leaned back, red eyes were full of nothing but affection. "Your so goddamn perfect, Izuku. You have no idea how happy you make me," he whispered against Izuku's lips.

They sunk into a deeper kiss as the alpha's rough hands began to take off Izuku's ruined shorts. He made a mental note to buy Izuku several of those in the future for future 'rematches' as he took off his own.

They both hissed at the feeling of his thick cock finally being set free as it brushed against the slick covering Izuku's sensitive areas. Without breaking the kiss, Katsuki swallowed the deep moan Izuku released as the alpha began to use Izuku's slick to pump their erections together.

Both of their breathing became erratic when Katsuki squeezed tightly, drawing out his new favorite sound out of Izuku. He stopped the kiss to pull back and begin to line himself to the twitching entrance waiting to be filled up.

Izuku's eyes stayed glued on the large cock as it began sinking into him and winced slightly when his ring of muscle started to become stretched all around Katsuki's wide girth. Red eyes saturated all the way to black as he watched how Izuku's face twisted in both pleasure and pain. The tight channel drew him in like Izuku's body was sucking him inwards and—fuck—he's swore this was the next best thing to heaven.

"You're doing so good," he praised, drawing the attention of green eyes to look up at him. "Keep your eyes on me. You're doing so goddamn amazing taking my cock like this," he whispered. Izuku nodded, keeping eye contact with Katsuki until they both moaned loudly when the alpha bottomed out.

"K-Kami, you're so big," Izuku whispered as his body clamped down on the hot intrusion, welcoming it. "You feel great." The omega's body began to shake with raw emotions as this was everything he ever wanted it to be.

"Just as great as you imagined?" Katsuki whispered, lovingly brushing their noses.

Izuku nodded feverishly and kissed him again. Katsuki held the burning eye contact as he rocked his hips experimentally. He guessed he must've brushed the right spot when a sinful moan rolled off Izuku's wet lips. Katsuki grinned like a feral man as he began to slowly pick up the motions, large hands finding their way all the way down to hold Izuku's hips as he plunged in over and over.

The loud slapping of skin echoed into the empty gym and the two lover's moans and cries mixed together to create a symphony of their union. The omega's legs that we were wrapped around the alpha tightened with need as the greenette began to cry out loudly with each deep thrust that shocked his pleasure button and sent ripples of ecstasy all over.

Every nerve in Katsuki's body felt like it was lit on fire as he was overwhelmed with Izuku. He would feel the greenette's fingernails dig in deeply to his shoulders, trying to hold on as Katsuki picked up the pace. He didn't hold himself back because he knew Izuku could take it. The omega below was stronger than any alpha he knew, and he could take a pounding like no fucking other.

"Ha-Harder!" Izuku demanded as he arched into him. "C-C'mon, Kacchan, fuck me harder than that. Do it like you mean it," he moaned out, curling his toes.

A challenging growl fell from Katsuki's lips as he pulled out to shift their position. Before green eyes could blink, Izuku felt himself get flipped over and was propped on his knees. The alpha pushed his head down to the plush mat and his fingers gripped the thick green curls at the roots.

Izuku turned his head to the side and grinned up at the alpha above him, flushing deep. "That's more like it. Fuck me till I'm screamin—ah!"

Without warning, the alpha thrusted his entire cock back in the warm heat, slick pouring at the forceful movement. The grip in Izuku's hair grew tighter and Katsuki began to slam into him from behind, setting a sharp pace. Izuku's moans filled the empty space when the large dominating alpha began to fuck graciously into his wet tightness that was dripping all over the cock deep inside of him.

"Like this?" Katsuki hissed, wrapping his free arm around the slim waist to steady the smaller body and to take Izuku's dick in his hand. "You wanna take my cock full force, huh? I fucking knew you had it in you," he growled out, slamming and jerking his hips forward, loving the new view of Izuku's perfect ass bent over in front of him.

"Yes!" Izuku called out happily, breath hitching when his head was pulled off the matt so Katsuki could see how wonderfully blissed out he looked with saliva dripping from his mouth. "Hng! More! M-More!" Izuku begged and Katsuki complied happily.

The blond's grip on the narrow waist tightened to the point he was sure there would be bruises as he chased after both of their orgasms. He made sure to keep his cock angled just right to keep Izuku moaning and calling out for him, each word from the omega edging him on to go harder, and faster, and pleasure the gorgeous body more.

The heat in his lower stomach grew hotter with each second, building up like smoke about to explode. He guessed Izuku was being drowned in the same type of endless ecstasy when he felt the tight ass clutch around him, trying to milk him clean. Katsuki continued to pound in ferociously, loving the sounds he was able to push past Izuku's lips with each thrust. He loved the squelching sound and feeling of slick overflow onto the matt below them.

The tight feeling gathered into of Katsuki's stomach felt like it was about to give and he sped up, feverishly jerking his hips as he felt the base of his cock start to swell. The smell of honey and caramel danced together and intertwined perfectly making Katsuki's knot start to grow.

Right when he felt himself about to tip over and pop his knot fully, he heard Izuku call out for him.

"A-Alpha, I-I'm going to cum," Izuku warned, face completed enveloped in euphoria. Green eyes were closed fully, losing himself to the pleasure. The delicate voice cracked high with another uncontrollable moan when pleasure shot straight up his spine as he felt the thick knot begin to slam against him.

"Alpha! Hng—ah! Knot me, fuck! Katsuki, knot me, please!"

Hearing his title made the primal feeling of need to claim and protect claw its way through Katsuki's chest and he gave a deep rumble. The vibrations shocked all the way down Izuku's spine, and the omega gave a short whine as he tilted his head, fully exposing his bare neck again.

"I-I'll knot you really fuckin' good," Katsuki groaned, vision going blurry with intense desire. "Fuck, I'm gonna fill you up."

Neither could control when Katsuki bent over the smaller body, pressing his chest against Izuku's arched back as he continued to fuck the other male. Izuku let out a soft keen when he felt hot breath and the feeling of razor-sharp canine rake across his neck, causing a trail of goosebumps.

The hand in green locks tightened and pulled Izuku's head further to the side as Katsuki sunk his teeth into Izuku's neck and his knot all the way inside the slicked up tight entrance.

Izuku's voice cracked high and he cried out at the overwhelming feeling of being filled. His body shook violently as pleasure pulled him past the edge and he shot out ribbons of white cum on the dark blue mat beneath them.

Katsuki gave a hoarse moan as he felt the tight body he was seated inside clamp down furiously on him, making his own orgasm come rushing in like a tidal wave. His vision went white from the feeling of himself cumming so hard as he listened to Izuku's high pitched cry. He emptied fully inside the wet canal, filling the omega to the brim with his cum.

Several silent moments went by as the two slowly climbed down from their peak. Their ragged breathing echoed out as they tried to cool down from the blazing fire they had just started. Katsuki rested his head against Izuku's shoulder, and the greenette's knees finally gave out, making them both lay down on the mat.

"That…" Izuku breathed, trying to catch his breath. "T-That was amazing, wow." The omega rested his forehead against the floor of the ring, still fully relishing the feeling of Katsuki stretching him out and filling him all the way.

The alpha nodded in agreeance at the statement because that was something he's never experienced. Before, letting himself lose care and control like that. He moved his hand underneath Izuku to touch the smaller male's belly and he could feel the light bulge protruding from the omega's stomach.

He smiled into the new claim mark on Izuku's shoulder. "I'm sorry for knotting you," he said half-heartedly. "Should've pulled out."

The freckled male just laughed and wiggled his hips, causing Katsuki to have to stifle a moan. Izuku turned his head to the side where Katsuki was nested and gave an affection smile when the alpha pulled back to look down at him.

"It's okay," the omega reassured. "I couldn't imagine my first time happening any other way."

At this the blond laughed and ruffled the messy green curls lovingly. "You know, I always imagined conceiving my first child on this mat, not going to lie," Katsuki confessed with humor in his voice.

"Of course that's a fantasy of yours," the greenette laughed. Izuku's grin spread wide and beautiful chuckles filled the room. "Well, if that's the case, I think this should be a regular arrangement, don't you?"

"Hell yeah, wanna have another 'rematch' later tonight then?" Katsuki gave a dull rock into the omega and loved the small moan Izuku stifled. "This time we can test out how sturdy my bed's mattress is."

"I like the sound of that," Izuku swooned. "How about we go get food first before continuing this?"

Katsuki gave a delicately placed kiss against Izuku's temple and wrapped his arms around the smaller body beneath him.

"Of course," he smiled into Izuku's hair. "Anything for you."

3 Years Later

"Ladies and gentlemen, the moment you've all been waiting for!" The announcer called out to the cheering crowd.

"Give it up for the reigning champion for two years in a row, Liiooonheaaart! Our beloved champion took some time off for family, but now, the symbol of empowerment has returned back to the ring!"

Izuku stepped into the caged ring wearing the colors olive green and orange for his fighting gear. His bright smile shone like the sun as he waved to all the fans in the crowd going wild for him. Various signs were being held up that read 'We love you Lionheart!', 'Symbol of Victory + Symbol of Empowerment = Love' and 'Wonder Duo is the best duo'.

Katsuki watched proudly as he settled their newborn daughter in his lap in the V.I.P section next to Nana. The dark-haired woman was besides Toshinori and gently smiled at him.

"Do you want me to hold her?" Nana asked as she pushed a blond curl out of the baby's face. She felt her heart swoon when bright green eyes looked up at her with the same look Izuku would always give her.

"No, it's okay, I got her for now. Thanks though, Auntie." Katsuki smiled at the other alpha who gave him a gentle nod.

Toshinori grinned brightly as Izuku headed towards the middle of the ring to stand next to a tall burly looking alpha. All three Plus Ultra coaches started cheering loudly when Izuku gave that award-winning smile.

The number two pro fighter looked down at his daughter in his lap and playfully clapped her hands together for her as the announcer approached Izuku. "C'mon, Aiko-chan. Gotta start practicing now if you're gonna be your papa and dad's biggest fan."

"Katsuki, you know she can't understand you, right?" Kirishima teased as he entered the VIP section with food for the new pup. "Don't tell me you're gonna be that type of dad."

"Never too early to start training them," the young alpha laughed, flashing his signature smirk. "If she's the daughter of the famous wonder duo, she's gonna be a fuckin' force to be reckoned with. A real fuckin' legacy."

Everyone shook their heads but chuckled light-heartedly at the joke. The lights flashed once to draw everyone's attention forward to the ring.

"Now, Lionheart," the kind smiling announcer began. "Many are curious about the recent name change from Alpha Slayer to Lionheart. Could you explain it to us?"

The greenette nodded dutifully as he stepped forward into the microphone.

"I changed my name because my hero who believed in me from the start told me he fell in love because I was brave." Izuku paused and glanced off to the side at Katsuki sitting on the side. Both men felt their heart swell to the brim with love.

"He told me that I was the bravest person he ever knew, and I felt like that was more important than holding on to the ugly past that had birthed the name 'Alpha Slayer' because I love him and my daughter more than anything."

"Well, I think Lionheart is very fitting for the very symbol of empowerment himself," the announcer said with a bright smile. "Many love the omega-centered MMA classes you and Shimura Nana have started hosting at Plus Ultra Studios. Not only is it progressive, but it's drawing out some serious talent from the shadows! If anyone would be named Lionheart, it is definitely you!"

The crowd went wild and Izuku gave a shy smile as he scratched the back of his head. The alpha standing in front of him nodded in recognition.

"Now, let's get started!" The announcer called out. "Fighters, shake hands!"

Izuku held his hand out for the large alpha in front of him and the strong hand gripped his with equal respect.

"Take your stances!"

Katsuki watched as the telltale look of competition but more importantly, passion, spread across Izuku's handsome face. The omega took an offensive stance that Katsuki had taught him and the young alpha lovingly kissed the top of his daughter's head in anticipation.

Red eyes briefly locked with green and Katsuki blew a kiss to his new reason to keep fighting.

"Aaand fight!"
