For the Rest of Our Lives

Summary:

Katsuki had no filter and no self control when it came to Izuku. He had no idea how it fucking happened, but somehow, in the middle of training, even though he lost a bet, somehow he had fucking won.

How did losing end up feeling like victory? Simply because apparently Deku asked him to go to the Light and Hope themed Cultural Festival UA was hosting that Izuku had been a big part in organizing... the kicker...

IT IS A FUCKING DATE! THEIR FIRST FUCKING DATE!

Save to say Katsuki was a smorgasbord of excited, nervous and freaked the fuck out.

Notes:

The second I got the prompt inspiration hit me cause I always wanted to write the BkDk crepe date and dammit I did it. Enjoy the fluff fest. Minor mentions of post war spoilers but this is all about the fucking fluff my loves.

Work Text:


Bakugou Katsuki didn't get nervous. He was steel forged from iron, unyielding, immovable, absolute with his victories and the best at everything he put his mind to. Yet here he was, the night of the UA Cultural Festival, standing by the front of the class 3-A Heights Alliance sweating up a storm, pulling at the cuffs of his long sleeved dress shirt, waiting for Izuku.

To think losing to Izuku's team during a training exercise would lead to this, a fucking date between him and the fucking adorable nerd to the festival. Fuck since the war and their talk in the hospital, the two of them had gotten so much closer, the rift no longer existing between them and they flourished. Their teamwork was otherworldly, their skills unparalleled when they were teamed up together, and even apart. 

Fucking nothing beat the feeling of chasing Izuku and working towards becoming heroes with the nerd and time had done wonders for the nerd's confidence. His mastery of One for All just got better because it seemed that by some miracle, it seemed that Izuku had retained One for All before Katsuki remembered the day Izuku came to him in tears that he had had a dream and spoken with the first and second and they told him that One for All had merged with him now, that it had become his own.

That Izuku would never be considered quirkless ever again because One for All was his and his alone.

Katsuki remembered that that was the day he realized he was in love with Izuku, the euphoric feeling of realizing he and the nerd would be heroes together forever, that that childhood dream would come to fruition... suddenly forever felt so much more than just a promise of being heroes. It felt more than a reason for a legacy, but more that it would not feel right if Izuku wasn't there by his side.

Then became what the band of idiots called the Cute Aggression Gay Panic Pining arc of Katsuki's origin. Fucking Denki and the purple haired hobo 2.0 were the ones to point out how pathetic his longing was and then fucking Monoma, the bitch started pointing it out to him too. How the fuck Monoma of all people became his friend he will never know but Mindfuck always likes to say, assholes attract assholes so it was bound to happen, especially when they were forced to have therapy sessions in the same place from the war. 

When Monoma wasn't being a complete shit stain, he wasn't that fucking bad... though he laughed anytime Katsuki self combusted after an episode of gay panic when Izuku was in his presence. It was so pathetic but dammit he couldn't help it. Izuku was so damn fucking hot, adorable, frustratingly cute and idiotic and nerdy and Katsuki was a pathetic obsessed simp merely thinking about the nerd.

The amount of embarrassing events the goon squad had witnessed was humiliating but he couldn't help it.

The fact that his friends fed his obsession wasn't helpful but he fucking took it with an aggressive feral hiss and threatened to kill them if they said a word as he obsessed over the nerd content like a creep. The amount of fucking cheering those idiots did when Izuku asked him out was insane but Katsuki couldn't blame them because even he himself never believed they would ever witness the scene of a mutually shared confession between Katsuki and Izuku.


Fucking fuck, Katsuki had to admit fucking Deku had him this time. As he lay on the floor, quirk cancelling cuffs on his hands as the Hobo announced that Deku's team won the exercise. Curse Katsuki for getting distracted by Izuku's fucking contortionist bullshit whilst they were grappling in the air before Katsuki took a full cowling combo to the fucking face. Fucking nerd's hair had come out of it's ponytail making him look like a fucking princess hovering above him with the light of the sun illuminating his fucking freckles that Katsuki had committed to memory before his cheek was caved in.

"Wow Kacchan that was an excellent battle." Izuku said as he crouched down by Katsuki, face hanging around his face as he smiled down at Katsuki whose face flushed pink at the way Izuku looked so pretty above him, tucking a strand of his hair behind his ear as he looked down at Kacchan with so much happiness, Katsuki felt like his heart was gonna explode all over again. Fucking get yourself under control Katsuki he told himself as Izuku did this fucking cute head tilt as he looked over Katsuki's face with slight worry. "You good Kacchan?"

"Yeah, that full cowling was particularly nasty nerd. And that was without your steel toes." Katsuki said as he felt the swelling of his cheek and the blood in his mouth as found himself smiling ferally at Izuku, not really caring about the blood that was probably staining his teeth. "You're so fucking good Deku." Katsuki said, proud and breathless as Izuku beamed, freckled cheeks flushed pink reminding Katsuki of strawberries. 

Damn he wanted to fucking bite his cheeks and chew on them forever like a fucking jaw breaker.

"Thanks Kacchan. I took your advice last month and have been working on my core and movements to make less style and more impact and substance." Izuku said as Katsuki bit the inside of his bleeding cheek as Izuku took his hands in his own, moving to deactivate the cuffs and all that was running through his head was fuck, fuck fuck fuck as Izuku's hands were touching his own goddammit.

"Good job Nerd, fucking kick ass." Katsuki said, voice gritty and tight as he barely kept his shit together, glad that therapy had taught him how to be more open with his words and with Izuku it came so much easier. He sighed as he felt his quirk thrum to life after the cuff's deactivated and he was free as Izuku smiled, and Katsuki groaned, knowing what was coming.

"Yo Baku-bro that fight between you and Midoriya was sick." Kirishima said as he and the rest of the class arrived for the Aizawa's final assessment of their exercise as Izuku helped Katsuki to his feet.

"Yeah like seriously, that was some wicked moves Izuku. You and Toshi totally got me and Katsuki." Kaminari said as he joined the group, Shinso's arm wrapped around his shoulders as Kaminari beamed at his boyfriend, "I was caught off guard when you mimicked my voice? The fact that Katsuki leapt to try rescue me made me feel so warm and fuzzy inside."

"I can make you warm and fuzzy on the outside too." Katsuki said in a threatening voice as he raised his hand which was sparking as Kaminari 'eeped' and hid into Shinsou's side.

"Please kindly don't threaten my boyfriend with innuendos of affection. That's my job." Hitoshi drawled out making Katsuki splutter at the suggestive implications and pulled a disgusted face.

"Gross, keep it off campus please." Monoma said as he and the rest of class 3-B joined them as Katsuki groaned, so done with the situation and was turning to walk away but stopped when he felt a hand take his own, making him still. The rest of the class was silent as Katsuki turned around and looked to see Izuku holding his hand, their fingers being laced together intentionally by Izuku who was focused but cheeks were flushed pink.

He was doing that nervous thing with his thinking face as he muttered quietly to himself, obviously psyching himself up as Shouto said from behind Izuku, "Izuku, you're muttering. Just ask him." He said with an encouraging tone. Fucking therapy, The fuck did it do to all the emotionally constipated idiots.

Izuku was shocked out of his stupor and bit his bottom lip as he looked into Katsuki's eyes, "I won, right Kacchan?"

"You did." Katsuki said as he tried not to lose his mind at the way Izuku was examining Katsuki's bare hand, the one that had lost it's glove when Katsuki managed to escape black whip and Katsuki was doing everything in his power to not explode as Izuku held his hand.

"I caught the Kacchan." Izuku said with a giggle, eyes sparkling the same way it did when he rambled about heroes and quirks and battle strategies. "I get to have my reward I was promised right?"

Katsuki swallowed sharply but nodded, not really sure where this was going. He remembered the competitive dumb game when Izuku was training his quirk and how he promised when Izuku really beat him in a decisive victory, he could ask for whatever he wanted. That time had come and Katsuki braced himself for all the possibilities that the nerd could ask him.

"I want to go to the Festival... with Kacchan... on a date..."

Out of everything that Katsuki imagined being asked... this requested was filed in the never ever going to fucking happen so stop being a delusional asshole category in the back of his mind.

What the fuck? Katsuki felt the air leaving his lungs as he stared at Izuku like he had just shed his skin and turned into Shigaraki, "Um... what?" He heard the way everyone gasped dramatically, Mina hanging dramatically on Kirishima's arm as she smacked him as if she couldn't contain herself and to be honest, Katsuki was barely holding himself together as he stood there like an fish with his open mouth catching flies.

"Fuck sakes Bakugou! Get your shit together and give him an answer dammit." Monoma groaned as he jabbed his finger hard into Katsuki's side making him hiss and come out of his floaty realm of delusion to realize this was reality. Izuku had just asked him out on a date. 

Katsuki stared at Monoma with wide eyes, "I heard him right? I'm not hallucinating or been hit by a quirk?"

"Oh God Bakugou, he did you fucking constipated Pomeranian." Monoma groaned as the others cheered, having come out of their stupor as Katsuki looked at Izuku with wide eyes as the nerd seemingly wilted beneath the gaze as he rubbed the back of his neck with his free hand.

"Kacchan... you don't have to feel pressured and-"

"No, Maybe, Yes I mean fucking yes Nerd!" Katsuki said in a panic as he tried to get his shit together as he looked at Izuku with seriousness. He breathed in a harsh breath as he tightly squeezed the nerd' s hand tightly in his own. He felt calmer than he ha in a long time as Katsuki looked at Izuku with all the seriousness and love in his gaze as he smiled, awkward and stupidly happy as he spoke, "My answer is yes, Izuku. I wanna go out with you... not just once though... I'm all in for the long haul... not just once... cause it's only ever been you."

Izuku looked ready to cry but his smile smothered all the tears that threatened to fall as he nodded, "Me too, I want that too." He said with a warm smile as he squeezed Katsuki's hand and beamed like he had just seen the radiance of the sun for the first time. "I... we can make the arrangements after class. I don't want to invoke Aizawa-sensei's wrath any further with teenage antics." He said as they both looked at Aizawa who was waiting patiently although he looked totally done with this shit.

"Cool." Katsuki said with a bright smile, as he remained holding on to the nerd's hand as they got their feed back, feeling stupidly euphoric and happy.


The idiot squad hounded him after he and Izuku met up after class to talk and confirm that yes, they had actually agreed to go on multiple dates, not just one and when they sat and talked about it, they realized this is something they had both seemingly wanted this since second year and they did not want to waste anymore time. They spent more time together than before, falling into the intimate comfort that went beyond the standard friendship and it was so fucking good.

So when Izuku declared that even though they were going on their first date at the festival a few days after they agreed to go to the festival, when Izuku said he hadn't envisioned being with anyone but Kacchan, Katsuki blew caution to the wind. When Katsuki looked at Izuku he wasn't filled with fear, but rather certainty and confidence in his choice as he listened to Izuku speak the feelings Katsuki was reciprocating, that forever really meant forever in everything, not just being in each other's lives, Katsuki asked Izuku to officially be his boyfriend and the nerd said yes.

The fucking class went ballistic with excitement and happiness the next morning when Katsuki came down and hugged Izuku in full view of everyone and told the shitty extras that Izuku was his boyfriend, it was a fucking great feeling. Knowing how far in this life they had come, that everyone was mutually happy for them, hugging the two of them as others paid bets towards Aizawa's open hand just making everyone erupt with warmth and laughter.

With the festival being two weeks away, Katsuki had had a conundrum, and it was that he didn't fucking know what the fuck he was going to wear on his date with Izuku so he had the help of the goon squad to figure it out. Having been an emotionally repressed asshole for most of his life, he had never been on a fucking date in his life and he'd rather die than confess to his mother that he was nervous about going on a first date with the nerd, let alone ever.  

Thank fuck Mina was helpful with helping him figure out what to wear and shit because Izuku had asked her for styling help so she did him a solid. She'd found that red shirt and vest combo he'd worn when they went to I-Island in their first year and got Momo to customize a new look from it. He was wearing a red button up shirt with the sleeves rolled up and the top two buttons undone and a pair of black jeans and a form fitting black leather jacket. He had to give it to pinky, she did him good without compromising him or embarrassing him.

"Looking good Baku-bro." Kirishima said, dressed comfortably as he too was excited for his date with Mina, patting Katsuki on his back. "Mina did great."

"You and Izuku both look great." Todoroki said as he come down the stairs with Sero on his arm, the two smiling like ridiculous idiots who got the shit together faster than Izuku and Katsuki did. 

"Yeah Izuku really is gonna kill people today with his outfit. Mina really went all out. Don't think I've ever seen a man look so handsome and beautiful all at once." Sero said as he ran his fingers over his growing facial hair, having decided to go for a more matured look after his growth spurt. 

"Fuck, are you trying to make me explode." Katsuki groaned, unable to believe just how easy it was to finally be able to talk about this shit after all the help he got. "I'm nervous as fuck but more because I still can't believe he's my fucking boyfriend. Still wake up wondering if its actually real and then I see his nerdy good morning text of aggressively stupidly cute emojis and realize it is real as I try not to fucking destroy my phone again. Its already the ninth one this month and the hag's teasing is pissing me off."

"I am still regretting my part cause its so disgustingly adorable seeing you two be so in love." Monoma said as he walked up with his arms crossed over his chest, Shinso and Kaminari joined them from the Heights Alliance. "Oh wow you lucky bastard." Monoma said as Katsuki pulled a face and turned round and felt his eyes widen as Izuku came out the building with Mina, giggling and smiling a smug smile but Katsuki's eyes were all over Izuku.

Nothing prepared him for Izuku with his long hair down, framing his face in a beautiful, ethereal way, his hair held back out of his face by a silver firefly hair pin with orange and red wings, a light application of make-up accentuating Izuku's beautiful features, accentuating and highlighting those freckles that made Izuku so perfect. Izuku's torso was exposed as he was wearing a orange crop top underneath a black rhinestone mesh top. On top he was wearing a body chain harness dotted with red stones in the silver metal that framed all of his toned features, including the sinful lithe waist and his abs.

He was wearing a pair of long bell bottom white jeans and what looked to be a pair of black healed boots, fuck what had Mina done to the nerd. He made him look so pretty but so masculine and hot that Katsuki's face was red as he stared open mouthed at his date. The fact that Izuku was so confident in his skin and with his body and his scars as he smiled nervously as he stopped in front of Katsuki and played with his hands, "Hey Kacchan."

"Hey Princess... fuck I mean, Izuku dammit." Katsuki said as he nervously rubbed the back of his neck, sheepish but he noticed the way Izuku's cheeks flushed pink at the nickname, "Wait... did you like me calling you that?"

"It's not the first time I heard you say that to me and I like that you think I'm pretty enough to be compared to a princess." Izuku said as Katsuki groaned, leaning forward and wrapping his arms around Izuku and buried his face in his neck, "K-Kacchan?"

"You're too fucking much for my heart sometimes." Katsuki said as he sighed as he felt Izuku hug him, "You're so pretty and so hot it does things to me. The fact that you dressed up like this for me makes me lose my mind and I just wanna eat you up and then lock you away and not share you with the world. I didn't realize how pathetically obsessed I was with you until now." 

"Well I guess we are both pathetic since I've been obsessed with everything Kacchan since I was little." Izuku said with a giggle as he pulled back so Katsuki could pout at him but sighed as Izuku reached up and cupped his face in Izuku's hand, Katsuki sighing as he nuzzled Izuku's hand, groaning quietly to himself when he realized how much of a pathetic, weak man he was when it came to Izuku. 

He did not realize he was a touch starved, thirsty man was for physical affection until Izuku started initiating it more and more and now he couldn't live without it even if he did it in public, he didn't care. Izuku made him weak and Katsuki liked it, made it all the more real cause Izuku also gave him strength. When he was with Izuku he felt like he could accomplish anything and he was stupidly in love with the nerd and was so glad he did. 

"Alright enough flirty confessions in front of all of us who are still single." Monoma droned on dramatically as he he turned on his heel, "If you wanna get to all of your plans on time, you got to stop staring into each other's eyes." He said as Katsuki sighed and glared at Monoma but Izuku just chuckled and moved to lace his fingers through Katsuki's and gave his hand a squeeze.

"Ignore him. We're together and I couldn't be happier." Izuku said as he leaned his head against Katsuki's shoulder, making the man groan as he watched the squad taking photos of them to memorialize the occasion. 

"Fuck lets go and do all the shit you want, Nerd." Katsuki said dramatically as he pulled Izuku along, who giggled excitedly as the others trailed behind them.


Izuku and the team had done a fucking incredible job with all the other members of the classes to make such a beautiful festival. The lighting, the designs, the theme, everything was ethereal and beautiful and almost indescribable.  The nerd took him everywhere, took him to the game stands, the play, even a fucking couple's contest which they actually won because they were the fucking best after all. Katsuki was almost fucking feral with excitement when he won a free limited edition All Might collectable plushie and card collection for obliterating a game challenge.

The nerd swooned as Katsuki came over with the nerd hoard, loving the attention as Izuku kissed his cheek. It took punching himself in the gut to not explode, much to the delight and humor of Izuku. And then they went and got some food, sharing fucking crepes like Katsuki had promised and sitting on a forest themed Ferris wheel ride made by the support course. They made so really intricate project shit that made the inside of their pod look like a romantic forest filled with fireflies and romantic ambience that Katsuki couldn't fucking comprehend.

Everything with Izuku though, it was so easy, so perfect as they arrived at the top of the ride and got to see the entire festival and take in this moment. Katsuki didn't even fight it when Izuku pulled out his phone and shyly asked for a picture. "Of course you can nerd. I am happy to oblige." Katsuki muttered as Izuku pressed his face against Katsuki's as he moved to take a photo of them. 

Izuku immediately opened his gallery and examined the picture with a beaming smile so wide it made his cheeks puff out adorably that Katsuki couldn't help but lean in and bite the cheek nearest to him. It made Izuku squeak as Katsuki snickered and nuzzled his cheek, "Sorry you are too cute I couldn't contain in. You make me wanna bite you all the time and it's frustrating but I like being able to express that I enjoy how it feels."

"I never thought I could be happier than the day I received All Might's quirk but you saying yes to going out and being my boyfriend beats all that." Izuku said in a dreamy tone as he turned his head and looked into Katsuki's eyes with so much warmth and love. "I never imagined this would happen Kacchan... especially not that day when I thought I'd lost you forever."

Katsuki knew it was still hard for them to talk about it, but he knew in that moment just how constant he wanted Izuku to be in his life, in his orbit, in his existence. Izuku was the explosive dynamite that kept his heart racing, that brightened his day and made everything so much more. He didn't want anyone but Izuku and now that he had him, he would never let him go. "You were my last thought then, and my first thought when I can back. You're my first thought every day and last thought every night. I plan for forever and every life time, so you're stuck with me you adorable bastard."

"I wouldn't want it any other way." Izuku aid with a smile as he turned to fully face Katsuki, who mirrored the posture, though he reached up with his hand, cupping Izuku's face with his hand and smiling at the nerd as he held him like he was something precious which Izuku was. "Today has been perfect, and I never want it to end."

"It won't because we're together now, so every day will be perfect and magical cause its us." Katsuki said as his eyes glanced down at Izuku's lips as he licked his own. "Wanna make it even more perfect?"

"Fuck yes." Izuku said, breathless and giddy as Katsuki burst out cackling as he descended and kissed Izuku the way he'd been fucking wanting to since the moment he realized he was fucking ass over mouth obsessed and in love with one Midoriya Izuku. It was everything he'd imagined and fucking more, it was euphoric, like when his quirk awakened further and he'd realized he could still keep up with Izuku. It was like a drug, addictive but never satisfying, only the desperation to have more burning in his veins as he slotted his fingers into Izuku's hair and tugged on the green locks, tilting Izuku's head more to deepen the kiss as Izuku let out a soft gasp and Katsuki turned ravenous.

He didn't know how to fucking kiss but fuck he was thankful he was somewhat paying attention when Mina explained how to kiss and he tangled his tongue with Izuku's the two battling in the kiss but fuck was it perfect. It was wet, messy and unco-ordinated the but the longer he kissed Izuku, the more the came together just like they always had and it was so fucking perfect. He felt Izuku smiling against his lips as they parted, the nerd giggling as he pecked Katsuki's lips, giddy and beyond happy with those freckled pinch cheeks, sparkly green eyes and blinding smile as Katsuki leaned his forehead against Izuku. "I don't think the happiness I felt when receiving One for All compares to how happy I am now."

"Fuck  you're too fucking cute dammit." Katsuki said as he couldn't contain himself and bit the nearest strawberry cheek, making the nerd giggle as they felt the Ferris wheel moving again but it didn't matter. The two of them were blissfully happy and in their own little world as Katsuki kissed Izuku's cheek, "Feel like fucking prince charming getting his happily ever after with his perfect prince or princess or some shit dammit."

"I don't mind you calling me Princess sometimes as long as it's between us." Izuku said with a giggle as Katsuki groaned and buried his face into Izuku's neck as the nerd giggled with so much love and affection that Katsuki never wanted it to end.

And it didn't because when they debuted as a number four duo right out of graduation and within a year broke the records of becoming the youngest number 2 heroes after moving in together right out of high school, surpassing Hawks and at the end of that year became the number one Duo, the Wonder Duo, Katsuki got down on one knee and proposed in front of everyone, declaring that he only deserved the best and the best had always been by his side, chasing him down till Katsuki had to be the one to catch up and catch up he did. What started as a race between two rivals became a side by side race between two people who never wanted to surpass the other, just wanted to mutually shine together.

Izuku, his beautiful nerd, his princess didn't hesitate and said yes and it was better than getting number one in Katsuki's opinion. Winning, owning and having Deku's heart was better than number one and it only got better when they got married and eventually decided to make some little heroes of their own.

Katsuki didn't know that would happen the day of their first day but as they disembarked from the Ferris wheel and he looked at Izuku, he wanted all of it. As the fireworks set off in the sky, the fireflies and lanterns dancing in the air, Katsuki realized that life with Deku was always going to be the light of his life and the beauty of his world.

"Love you, Izuku." Katsuki said as he held Izuku's hand, looking up at the beautiful kaleidoscope of fireworks erupting in the night sky.

"Love you too Kacchan, for the rest of our lives."

"For the rest of our lives." 


The End
