Work Text:
Izuku could hardly contain his excitement as he threw open the heavy curtains covering the floor to ceiling windows, revealing a breathtaking view of the Sumida River and beyond it the shorter buildings of the surrounding neighborhood. The sun was beginning to dip lower in the sky, painting the blue with the softest hint of pinks and oranges. He felt Kacchan come up behind him as he placed a hand on his waist and snorted.
“Knew you’d like this,” he said confidently, squeezing Izuku’s waist.
Two weeks after Izuku’s 19th birthday, Katsuki revealed that he had planned an entire weekend away for Izuku, as a post-birthday treat. He’d said on the day that Izuku’s birthday surprises “weren’t over yet”... but to be honest, Izuku just thought he meant the sex that they’d had that night. The Sumidagawa Fireworks Festival always took place in Tokyo on the last Saturday of July, and he’d even bought two traditional yukatas for them to wear for the event – a green and white silky floral design for Izuku, and a plain silk orange one with a black obi for himself.
Katsuki had even gone the extra mile and booked a stunning hotel nearby which had a river view. He explicitly stated that it wasn’t a romantic decision, but rather because Izuku was a “fucking idiot who would only get blisters from wearing the geta sandals” and Katsuki “won’t carry him all the way back home like some fucking damsel in distress because this ain’t some shoujo manga”. It still didn’t stop Izuku’s heart from fluttering at the sentiment, though.
“Kacchan, thank you! I’m so excited! This sounds amazing!” Izuku practically leapt into Katsuki’s arms, with the blonde nearly losing his balance. “It’s going to be so romantic.”
“It falls on Raccoon Eyes’ birthday this year, and Shitty Hair is taking her. He talked my damn ear off about it all fucking shift, and it sounded like the same cheesy crap you’re into. But our date is gonna wipe the floor with theirs.” He brushed a lock of hair behind Izuku’s ear. His face twisted in annoyance when the lock flopped right back to where it originally sat.
“Firstly, you can’t beat someone at dating,” Izuku said with a giggle. “Are we gonna be meeting with them?”
Katsuki huffed out a laugh. “Only losers don’t think you can beat someone at dating. I’m gonna take you on the best goddamn date you’ve ever been on, nerd. And hell no, we ain’t meeting with those extras. Tonight is all about you.”
Izuku never would’ve thought that Katsuki would be the type of boyfriend to take Izuku on romantic dates, but ever since they began their relationship after the war in their second year at UA, he’d been spoiled rotten. He still chuckled quietly to himself at the thought that Kacchan was determined to take Izuku on the best date ever, since his competition was… well, himself.
He continued to ogle at the view of the river and the city until Katsuki tugged him gently away, pushing him toward the bed where he laid out the yukatas. Izuku admired the fabric and designs, particularly the sleeveless design on Katsuki’s. He loved when those strong, defined arms were on display just as much as, if not more than, Kacchan loved showing them off. The bulging muscles might be the only thing that could shut off Izuku’s brain.
“Is now a bad time to say that my mom always helps me with yukata?” Izuku asked.
Katsuki tried to hide the smirk on his face with a look of exaggerated exasperation. “Then it’s a good thing I’m the best at everything. I guess I’ll help. But I’m only doing this for me, ‘cause I can’t wait to see you in it. And then out of it later.”
Dressing took much longer than intended. Kacchan was slow and methodical with wrapping it, giving instructions that Izuku could not follow along with because each instruction was punctuated with a scalding, damp kiss on his chest, his shoulder, his neck, his jaw, his chin. Katsuki also made sure to jerk Izuku with his aggressive tugs of the fabric. Izuku didn’t mind, so long as Kacchan was happy to do whatever to him.
When he was dressed, Izuku offered to dress Katsuki in his own yukata. Katsuki smirked at Izuku. “In your dreams, nerd. You can watch so you know how to take it off.”
And Izuku hyper focused on each step of wrapping a yukata, from the specific side on top to the way Kacchan tied the obi. The sleeveless yukata suited him just well, and while Kacchan was not one to complain, Izuku figured the lack of sleeves helped him immensely in his comfortability in the warmer months, when his quirk was dependent on the sweat.
He tried to focus on Katsuki’s instruction on how the yukata should be tight on the back of a man’s neck, but it only made Izuku think about what he might do to Kacchan’s neck if it had been on full display for him to admire. What he wouldn’t give to lay a thousand wet, open mouth kisses to his tender porcelain neck, teasing the sensitive points with light nips of his teeth, biting a little harder with each encouraging moan vibrating against Izuku’s mouth, sucking a possessive bruise for the world to know that Great Explosion Murder God Dynamight belonged to him–
“Shitnerd, are you listening?”
He was supposed to be paying attention… whoops. “Of course!” Izuku lied.
Kacchan had always been able to see right through him, though, replying with a “tch'' as he finished wrapping the obi around his slim waist. “There’s usually food stalls and shit around Oyokogawa Water Park, so you’d better get moving else you’ll be so hungry you’ll start eating your own damn arm.”
“Hmm…” Izuku pretended to think about it, exaggeratingly stroking his chin in contemplation. “No, your arms have more meat on them.”
“You fucking–”
Izuku’s laughs and Katsuki’s curses followed them to the festival.
Oyokogawa Water Park was a sight to behold in all its festive glory. Their path towards the festival booths was almost tunneled with the white lilac trees hanging over the footpath. Either side of the pair was beautifully decorated with an abundance of hydrangeas, camellia and hanashobu, standing out starkly against the sea of green chrysanthemums and cymbidium orchids. Sumida River looked like a doorway to another realm with the ethereal way that the rainbow of colored flowers reflected off the water. The light summer breeze cooled Izuku from the heat that they’d endured on their journey here, and Izuku admired the lanterns glowing brightly against the setting sun.
“Kacchan, can we get okonomiyaki?” Izuku asked once they’d reached the food stalls and his mouth watered as the scent of the deep fried goods overwhelmed him.
“Hell no, that shit’ll clog your arteries,” his boyfriend scoffed rudely, not even turning to look at him. “It’s no fun beating you to the number one spot if you die of a heart attack in your twenties.”
“One pancake won’t kill me!” Izuku huffed out an exasperated sigh, hanging his head as he followed hot at Katsuki’s heels. Apparently finding a food stall that his boyfriend found acceptable was a much more difficult task than Izuku had anticipated, as he’d pointed out several other stands and was always met with a resounding ‘no’. Kacchan repeatedly grumbled about the poor quality of fried food. “What about takoyaki, then?”
“Would All Might let you eat that crap in a meal plan? That shit does not belong in the diet of a Pro Hero,” he asked with a quizzical eyebrow raise, folding his arms over his chest. Izuku was certain that his knees had given out for a moment as Kacchan’s defined arms only enhanced the shape of his pecs through that motion.
If that was the game that Kacchan wanted to play, then Izuku would bite. Shooting Kacchan a smug smile, he whipped out his phone and texted All Might there and then. “Hi, All Might,” Izuku narrated patronizingly, as his thumbs worked quickly over the glass screen of his phone. “Kacchan won’t let me eat any of the food here at the festival because he’s being a big baby about the fried food being unhealthy and he says that you’d hate it. Could I eat some takoyaki today as a treat?”
Katsuki’s eyes narrowed playfully, albeit with a hint of genuine irritation. “And I’m the big baby. Sure, I’ll buy you your damned grease balls if he agrees. I guess that it’s moderately better than the instant ramen and frozen 7/11 garbage that you normally live off.”
Izuku’s features flattened slightly at the remark, but he chose not to argue about it. Instead, the pair continued to browse the local stalls until his phone dinged.
From: All Might
Midoriya-shounen, I’m just pleased to hear that you both are having a nice time, you both deserve to enjoy yourselves! Have a night off from being Heroes – that includes the strict diets. Though I’m certain that Bakugou-shounen just cares about your wellbeing. I’m happy that he encourages you to eat well.
“Ha!” Izuku cheered gleefully and shoved his phone into Katsuki’s face. The blonde eyebrows knitted into a defeated furrow over every word, much to Izuku’s satisfaction. “Kacchan is the best boyfriend ever. I can’t wait to eat takoyaki with you.” His words dripped with sarcasm in an attempt to be playful, yet the words were totally sincere.
Mumbling something under his breath about stupid All Might being a fucking pushover and this stuff is pure fucking grease, Katsuki ordered two portions of takoyaki and the pair headed to a nearby seating area to eat.
“This is delicious!” Izuku said through a mouthful of food, earning a disgusted look from Katsuki.
“Don’t talk with your mouth full, you gross bastard.” Katsuki shot him an irritated glance, but it didn’t have much bite to it. He popped another takoyaki piece into his mouth, chewing politely, as he examined the nearby booths from their seats. “It’s fucking creepy seeing folk wear All Might masks at these sorts of events still. Like, I get that he was important and shit, it’s just that he was our teacher for three goddamn years.”
“I really like it,” pondered Izuku, stuffing more takoyaki into his mouth than he could clearly handle. “I mean, after all this time and after all we’ve been through, he’s still an icon loved internationally. He was the number one Hero for decades, and none of the other Japanese Pros, like Endeavor or Hawks, have come close to affecting society the way that All Might did. Not even us, after defeating All For One and Shigaraki. It’s nice that everyone still loves him and admires him. The impact that he had on society not just in Japan, but in the entire world, is really something…”
He had honestly expected Katsuki to interrupt him for nerding out, but instead was met with Katsuki’s full attention. His boyfriend continued to nod in mild enthusiasm as Izuku rambled on about All Might, picking at his own takoyaki.
Well, Kacchan was a secret All Might fanboy too.
“I’m not getting you one.”
“Kacchan!” Izuku pouted, swallowing his food dramatically. Before he could pester his boyfriend further, Izuku spotted something out of the corner of his eye. “Fine. Will you win me an All Might plushy from one of the matsuri booths? They’re authentic Silver Age designs that actually have the two toned cape and the accurate chest piece!”
Katsuki’s lips twitched up into a wicked smirk, a determined glimpse in his eye. “I guess so. If we compete, I’ll only win anyway.”
Of course, competing is something that actually got Kacchan’s attention. Izuku should’ve expected this, but he’d be lying if he said he wasn’t up for a little… friendly competition. “Deal, but when I win, I’ll give you the All Might plushy.” Izuku balanced his chin on his hands, gazing at Katsuki with a lazy smile and eyes like butter wouldn’t melt.
“I just said I was gonna beat you, you shitty nerd!”
After finally finishing their takoyaki between shouting matches which earned some very displeased looks from civilians around them, the pair headed to a shateki booth amongst the matsuri games.
The problem was, the shateki games did not go as Izuku had anticipated. It was pretty common knowledge that carnival games and the like were rigged against anyone who played them, but having faced off against some of the worst villains the world has ever seen, Izuku thought that at least one of them would be okay at hitting moving targets with a toy gun. This was not, however, the case. Izuku and Katsuki both failed miserably and kept missing every single target. They obviously had two very different techniques – Izuku overanalyzed the speed at which the bullet would hit the targets, which were perched on moving shelves, and kept fudging his estimates. Katsuki, however, just let his anger take over as he screamed at both Izuku and the poor man who ran the booth.
“I need you both to leave before you destroy my equipment!” The man cried, trying his best to sound stern, but was clearly terrified of Katsuki, by the way his voice trembled and he looked as though he was about to piss himself.
“Hell no, dumbass,” growled Katsuki, as bright orange sparks crackled in his palms. “Give me one more fucking try, and then we’ll be outta here.”
“Fine, but it will be three times the price this time.”
“Hah?! Are you fucking kidding me?”
“Kacchan,” Izuku hushed. “It’s okay, we can probably head over to the firew–”
“I’m winning you that damn All Might plushy,” Katsuki replied confidently, but still staring down the booth-keeper. He reluctantly placed a few yen notes in the man’s hand (read: slammed it into his hand) and hoisted up the gun, a fierce concentration suddenly striking him.
Seconds felt like hours the way that Kacchan was taking a leaf out of Izuku’s book with the overanalyzing. Every time Izuku thought he was going to pull the trigger, Kacchan stayed as still as a statue, and Izuku let out the breath that he didn’t realize he was holding. He really was taking this seriously, wasn’t he?
The sound of the bullet suddenly being fired startled Izuku and the All Might plushy dropped off the shelf with a CRACK.
As the booth-keeper handed Katsuki the prize, he turned to face Izuku with a smug grin overpowering his entire face. “Don’t ever doubt me for a second.”
Izuku yanked the toy from Katsuki’s grasp. “Kacchan, sugoi!” Izuku beamed and engulfed his boyfriend into a suffocating hug, nuzzling the plushy close to his chest. “Thank you!”
“Yeah, yeah. Let’s go see some fireworks then.”
The pair found a spot to stand near the pre-bookable seated booths. Normally, this amount of people would be driving Kacchan insane, but Izuku was pleased to see him keeping his cool even though civilians kept bumping into him every thirty seconds.
As the fireworks were about to begin, a hush fell over the crowd in anticipation while the booths around them started dimming the lights.
Amidst the hush and low lighting, Izuku hugged the All Might plushy tight to him, as his mind wandered to how nice it would be to hold Kacchan like that. Kacchan was normally very affectionate in private, always touching Izuku in some way – whether it be resting his feet on Izuku’s lap as they lay on the sofa, or an arm around Izuku’s shoulders as his nose was buried deep into the latest manga volume, but that wasn’t the type of touching that was on Izuku’s mind.
Their sex life in the Heights Alliance dorms was restricted to solely frotting; usually fully clothed during a passionate make-out session before they retired to their own rooms for the night, but other times they needed that skin-on-skin contact. Sexual contact was strictly prohibited in the dorms, and they also wanted to focus on their studies. Two hormone-driven teenagers discovering the bliss of penetrative sex could frankly take precedence over anything else, but it was a step that neither of them wanted to take right away. It was a mutual agreement to wait until they had their own place together once they’d graduated.
(There were a few extra reasons as to why Izuku and Kacchan chose to abide by the “no sex” rule: Number one, they didn’t dare be loud enough to alert Iida to their activities. The thought of Iida scolding them or, God forbid, Iida reporting them to Aizawa-sensei was… not pleasant, to say the least. Number two, Kacchan was always a stickler for the rules. Number three, Mineta was far too comfortable with Izuku and Kacchan’s sex life, especially since he shared a wall with Izuku. Ever since Mineta came out as bisexual, he spent a long time thirsting after Izuku and Todoroki, and earned himself a few explosions to the face from Kacchan for that).
So, they waited. Once they had graduated from UA and accepted sidekick positions in a large Tokyo agency a couple of months ago, they wasted no time beginning their lives together in their new apartment and finally moving away from their hometown of Musutafu. Finally, Izuku and Kacchan were allowed to sleep in the same bed! Izuku had no idea how easy it was to fall asleep with his head resting on Kacchan’s chest; the soft, rhythmic beat of his heart reminding him that he was alive. The last time they’d shared a bed together was when they were both in hospital following the war, and that was only because Izuku cried so much that Recovery Girl and Aizawa-sensei accepted it for one night. In Izuku’s defense, Kacchan died. Cut him some slack.
The first time they had sex properly was unplanned. Izuku, being the anxious pre-planner that he was, had an entire thesis worth of questions to ask regarding his boyfriend’s boundaries during sex, determined to learn every single desire that Kacchan might have. Instead, his brain short-circuited the second that Kacchan’s smart mouth latched around Izuku’s cock and swallowed him in one large gulp the night that they moved into their apartment. Calloused, warm fingertips gently massaged Izuku’s prostate as Kacchan continued to bob his head up and down his cock – Kacchan’s so amazing, even in bed.
From that night, every night followed the same set routine of Kacchan topping Izuku, albeit in a multitude of different positions. And as much as Izuku loved being filled by Kacchan, he couldn’t shake the feeling that it was time they tried something new.
With a sudden surge of confidence, he leaned into Katsuki and whispered in the blonde’s ear, “I want to fuck Kacchan.”
Katsuki’s entire face burns a shade of red akin to his eyes, whipping his head towards him. “Hah?! What the fuck did you say?!”
Izuku shushed him, especially when a few heads turned their way. He bowed his head slightly at the civilians, murmuring an apology. “Kacchan,” he said under his breath in warning.
Katsuki huffed, but spoke again in a heated whisper. “We ‘fucked’ this morning, you damned nerd. You can keep it in your fuckin’ pants until after the date.”
“Not like that.” Izuku brought the All Might plushy up to his chin, squeezing it for the confidence to continue. “I want to fuck Kacchan.”
There was no verbal response from Katsuki – only the sound of air getting stuck in his throat, as if he were choking on the words he’d meant to say.
Izuku shrugged at this, only turning slightly to regard him. He kept half an eye on the inky, star-freckled night sky above them, but mostly to just assume the air of nonchalance about his proposal.
He couldn’t help but steal a glance at his boyfriend, though – Katsuki’s cheeks still burned a ferocious crimson, which had now spread to the tips of his ears and down the back of his neck. His eyes, normally cool and collected, now wide and pupils blown, hiding most of the red irises that Izuku loved so much. Probably from the lack of light around them… but Izuku hoped it was from lust, too. Kacchan looked so beautiful in his orange yukata, the sleeveless one showing off his large, defined biceps. The reflections from the lanterns shone against Kacchan’s face in a way that almost made his cheek scar glow in the starlight. And despite the fold of the yukata cutting across it, the muscles of his broad chest were still noticeable. He’d even chosen to wear a sleek black obi around his traditional outfit, giving sweet definition to his tight, little waist that had been driving Izuku crazy all evening. He was having a hard time keeping his sex-driven thoughts to himself.
“I want to do so many things with you, including being inside you,” Izuku continued in a low whisper, still not meeting Katsuki’s gaze. “I want to be as close as possible to Kacchan.”
Katsuki replied with a guttural groan – frustration? arousal? – and buried his face in his hands. Even with Izuku’s vulgar language in such a public setting, nobody appeared to overhear the conversation, paying the pair no mind at all. Nobody seemed to know that two young Heroes who saved Japan from the evil that burdened it for decades were among everyone. Nobody seemed to know that the Hero who defeated Shigaraki was talking about putting his cock inside his boyfriend.
Izuku continued to study his boyfriend through discreet, stolen glances. The reaction he was receiving was encouraging, to say the least. “I bet Kacchan would be so tight around me. You really are the best at everything. You could probably suck me in and clamp around me with ease.”
It was at this point where Katsuki had gripped Izuku’s hand and hid his face into Izuku’s shoulder, trying to stifle his blush even more through Izuku’s silk green and white yukata. Even through the material, Izuku could feel the heat radiating off of Katsuki. Most of it was likely just because Kacchan always ran hot from his quirk, often leaving behind some dampness from his nitro-sweat, but Izuku knew it was mostly from Kacchan’s blushing.
“I just want to make Kacchan feel special,” Izuku finished in a murmur. He gave Katsuki’s hand a light squeeze and tried to focus his attention onto the night sky.
The firework display didn’t give Katsuki a chance to respond further to Izuku, as the sky was lit up with bright neon red and green lights. Seconds later, the thunderous boom of the sound followed suit, and Izuku stared in awe as the remnants of the last firework trickled down in a steady stream. The thick scent of gunpowder and smoke filled the air as more starshells bursted above them in an array of blues, yellows and reds. The reflections of the colors on the river made the sky look endless.
He was grateful to spend this beautiful moment with Kacchan.
He felt Katsuki move his head from his shoulder, felt the warmth of his breath on Izuku’s neck, sending chills down his spine. Katsuki’s lips pressed to Izuku’s ear, and in a dark, husky whisper, he said, “Okay.” The hand that held his own gripped tighter to punctuate this new decision.
For the first time since they began this conversation, Izuku tore his eyes from the sky and focused completely on the one thing more beautiful than the display. Kacchan’s face was close, and the reds, greens, blues, and golds of the fireworks illuminated his pale features, painting him in the most effervescent light. Izuku’s lips parted because he wanted to say so much, but his throat suddenly felt so dry. His heart beat loudly, echoing in his ears with the explosion of fireworks.
“Okay?” he croaked out finally.
Katsuki tucked his chin on Izuku’s shoulder again. He still looked shy about this, but there was that familiar determination in his eyes. “I trust you,” he said. “Those… things you said. I really – fuck.” He cut himself off, letting his gaze wander to the fireworks. “Repeat anything I’m about to say to anyone, and you’re fucking dead.”
Izuku shook his head fervently. “I would never! Kacchan is the only one I can’t keep secrets from.”
The blush that spread across Kacchan’s face and the little smile that toyed on his lips looked even prettier in the red and blue light. “Yeah, yeah. I know. It’s just… what you said… it didn’t sound half bad, I guess. I can’t describe it, but something about it flipped a switch in me. Besides, I told you I was gonna take you on the best damn date of your life, and if this is how you wanna conclude the evening, you got me.”
Izuku’s only response was tipping his head near Katsuki’s and capturing his lips in a kiss. He could feel Katsuki’s hum against his mouth and parted his lips to taste it. Kacchan mimicked his motions in a dance they had grown familiar with in their two years of dating. Katsuki slipped his hand from Izuku’s grip and placed it firmly on the small of his back, pulling him closer. Izuku’s own hand fit itself on top of the tight obi around Katsuki’s firm, tight waist.
Their tongues started to brush, when someone around them loudly called, “Excuse me!”
They pulled away from each other, a little breathless, and incredibly sheepish. Well, Izuku was sheepish. They were never a couple who partook in public displays of affection. Even holding hands in public was a special occasion. Katsuki, on the other hand, glared at the woman with two children who had interrupted them, as if he were plotting to do something very un-hero-like to her.
“Kacchan,” Izuku admonished again. His hand still held Katsuki’s waist, and he squeezed his side to grab his boyfriend’s attention.
Katuski heeled and pressed himself closer to Izuku. “Tch. There’s too many fucking people here.”
He was right. In the time since the fireworks had begun, the crowd of people around them had become more dense, and they packed closer to accommodate the mass filling in around them.
“It is a firework festival, Kacchan. There’s going to be people,” he teased with a boyish giggle, tugging on Katsuki’s yukata.
Kacchan was likely in half a mind to agree before a figurative lightbulb suddenly lit up above his spiky hair. Or maybe it was a firework in the distance. It was anybody’s guess.
“The hotel room had a damn good view of the fireworks,” Kacchan said with a wicked smirk, biting his lip devilishly and delicately playing with the baby hairs on the back of Izuku’s neck. It sent shivers down his spine. “How about we ditch these extras and make your fantasies a reality?”
Izuku would be lying if he said that didn’t go straight to his dick. He wasn’t sure how good his yukata would be at hiding a giant boner. Especially with the crowd pressing closer and closer.
In his panic, he grabbed Katsuki’s hand, lacing their fingers together, and started making an exit toward the hotel. He used the arm wrapped on the All Might plushy to part the crowd, whispering a quick apology to each passing person.
Kacchan quickly got annoyed with Izuku’s speed and grabbed him by the shoulder to allow him to pass and take the lead. Kacchan was less polite about pushing, charging ahead and shouldering past everyone. Izuku kept his head bowed in a permanent penitence as he heard complaints from every passing person.
When they finally escaped most of the crowd by the river bank and the booths, Katsuki glanced back at Izuku. Their eyes locked, carmine to veridian. Izuku could see the love in them. Could see it written on all of Kacchan’s features, the sharp angles soft with adoration and affection. Then Kacchan’s lips kicked up. It started to look like those signature smirks, the kind he always wore around Izuku even in Izuku’s daydreams, or when he’s facing off against a villain. But then his lips pulled back over his teeth, and Katsuki flashed Izuku a radiant grin.
Izuku’s heart pounded in his chest hard. He tugged Katsuki’s hand to stop him before yanking him close and kissing him again. Katsuki’s free hand went to Izuku’s head, fingers combing through the curls and pulling his head closer.
He only allowed Izuku to relish in the kiss for a minute, enough for lips to part and tongues to graze, enough to get him harder. Izuku could tell Kacchan was also working himself up, if the hardness pressed against his hip was any indication. Then Katsuki pulled back. The smile he wore was shy, with his chin lowered, peeking up at Izuku through his lashes. “Get your ass moving back to the hotel, before I make you take me right here, right now.”
“O-okay,” Izuku nodded fervently. And then he took off in as much of a sprint as the geta sandals would allow, pulling Katsuki with him and weaving through people.
“Don’t run in front of me!” Katsuki exclaimed, running even faster in his own sandals, passing Izuku. Their hands stayed linked throughout their race.
They made it halfway to the hotel when Izuku had to stop from pain coming from his foot. It was almost laughable because his pain tolerance was notoriously, abnormally high, especially when he was focused. He stopped, forcing Katsuki to stop, and bent down to examine his foot with a hiss of pain through his teeth. The strap of the sandal had rubbed a fat, raw, bleeding blister onto the side of his foot.
Katsuki peered down at it and scoffed. “I fucking told you that you would get a blister. Good thing we’re close to the hotel because I’m not carrying your ass.”
“Kacchan doesn’t have a problem carrying me and throwing me around when we’re making love,” Izuku retorted, rubbing at the sore and trying to adjust the strap so it no longer chafed. He straightened with a cheeky grin at the sound of a strangled gasp from Katsuki.
“Where did this filthy fucking mouth come from?” Katsuki asked, rubbing his face to hide the obvious blush.
“I learned from the best.” Izuku wrapped an arm around Katsuki’s waist and leaned in for a quick peck. He passed the All Might plushy over. “Please keep him safe. He's a limited edition.”
Katsuki took it, confusion painting his face. “Why do I have to–”
He never finished before Izuku released blackwhip, aiming toward the nearest building, and then the two of them were flying, with Katsuki held firmly in just a single armed hold. Katsuki’s arms quickly wound around Izuku’s neck, the All Might plushy hitting Izuku’s back in the wind. Izuku activated float as well to keep them in the air, when he let go of one blackwhip tendril and sending out the next.
It took less than a minute for Izuku to land them gently right in front of the hotel. Kacchan’s wild spikes looked even messier from the wind, and Izuku was sure his hair hadn’t fared much better.
Katsuki let his arms slowly fall from Izuku’s neck, trailing along Izuku’s arms and his chest before they fell to his sides. “Dumbass,” he grumbled, shoving the All Might plushy forcefully into Izuku’s arms. “You were supposed to be begging me to carry your whiny ass back to the hotel.”
“But you told me so many times that you wouldn’t carry me!” Izuku protested. “So I decided to carry Kacchan instead.” He grabbed the stuffed doll and then Katsuki’s hand, and together they went into the hotel. Izuku deliberately avoided eye contact with the front desk attendants and concierge, muttering a quiet greeting to them. He felt like they knew what they were about to do.
Katsuki hit the button for the elevator, and with every floor that counted down its arrival, Izuku’s heart picked up speed. They had sex before, but this was new. It was a new way to explore each other’s bodies, and while he desperately wanted it, he wasn’t sure how Kacchan was feeling about it.
Katsuki’s hand tightened on his, and it was then that Izuku felt how clammy Katsuki’s hand had gotten. Katsuki sweat more than the average person because of his quirk, and Izuku had grown used to it over the years, even before they had started dating. But he didn’t get nervous too often–or rather, he didn’t let anybody see his nervousness.
Feeling the dampness of his hand in Izuku’s made it feel all the more real. Izuku turned his head, staring at the profile of his boyfriend. The flush had taken permanent residence on those sharp cheekbones, dusting his pale skin in a pretty pink. His jaw was twitching as he worried at his lower lip with his teeth. His eyes were downcast, studying the tiles at their feet.
But then, as if he could feel Izuku’s stare, those ruby eyes turned toward him. Amazingly, Kacchan made no attempt to hide his turbulence. Instead, Izuku watched with great focus as his teeth gnawed on his lower lip more. Izuku wished that could be his lip in those teeth.
The elevator dinged, and the doors opened. Izuku wasted no time entering, yanking Katsuki with him, narrowly avoiding a couple exiting at the same time. The doors hadn’t even begun to close before Izuku lunged at Kacchan, pushing him up against the wall and locking lips. He pulled on that abused lip with his own teeth, and Katsuki’s moan filled the small space.
Hands wove around his hips, pressing him ever closer to his boyfriend, before roaming over Izuku’s yukata-clad body and muscles. Izuku followed by example, despite the All Might plushy still firmly in his grasp. He ran his hands over each muscle, feeling how each one flexes and relaxes.
They barely separate when the elevator arrives on their floor, stopping every other step to the room to kiss again. Izuku had already been an expert on the inside of Kacchan’s mouth, but he could write pages and pages on what it tastes like, what it feels like, how his tongue roams Izuku’s mouth, how his teeth make a frequent appearance to tug on Izuku’s lip. They kissed like they sparred, always fighting for dominance and loving every second of it.
Finally they reached their door, and Kacchan fumbled with the key without breaking contact. They parted only for a gasping breath while they entered, but when the door closed, Katsuki was on Izuku again, forcing him against the door.
Izuku quickly flipped them around, caging Katsuki in instead, to give him just a taste of what was to come. At this angle, with Izuku pressing into Katsuki, his hard-on pushed against Katsuki’s, and Katsuki arched into it. They groaned in unison at the sensation.
“Bed,” Katsuki demanded, bucking against Izuku one more time.
“Okay, okay,” Izuku whispered against his lips. He grabbed Katsuki by his narrow hips and walked them backwards toward the bed. They didn’t even remember to turn any lights on, as they had left the curtains open before leaving when the sun was still up. The fireworks display continued, illuminating the room well enough.
Katsuki turned his head, separating the kiss momentarily. “Izuku, I swear if that stupid toy whacks my ass one more time, it’s meeting my explosions.”
Reluctantly letting go of his boyfriend with one hand, Izuku continued to passionately kiss Katsuki while propping up the All Might plushy onto the spare chair at the bedside. Naturally, though, Kacchan had always been ridiculously observant; breaking the kiss to side-eye the plushy that now had a direct view of the bed.
“God dammit, put that thing literally anywhere else.” Katsuki rolled his eyes and was about to head over to the desk, but Izuku beat him to it. Without a second of hesitation, he threw his boyfriend onto the bed in a bold display of dominance. (Izuku might have used a small 1% of One For All to ensure that the push was effective). To further enunciate his point, he straddled his boyfriend’s lap, which was met with another exaggerated eye roll. “I don’t want the plushy version of our teacher watching his successor plough me into next week.”
Izuku opened his mouth to protest further, but Katsuki had wrapped his arms around his back to lock him into a firm embrace. He tried to escape the grip by writhing around on top of Katsuki, but it was a fruitless effort. Just when he thought he’d at least restrained Kacchan enough to focus on kissing again, Katsuki reached his leg out from under them. In a second’s notice, a set of toes clumsily grabbed All Might’s signature hairdo and threw the plushy across the room, hitting the door with a dull thud.
“Kacchan! That was mean. You didn’t like it when Shigaraki did that to you,” Izuku said without thinking. Once the words had left his lips, he immediately darted his gaze back down where he was met with vermillion orbs that stared into his soul. They weren’t there for long.
“Too soon!” Katsuki screamed so violently that his pupils had actually vanished for a moment, leaving nothing but two huge, white, upturned crescents in their absence.
But Izuku knew Kacchan better than anyone.
There had been a lot of emotions surrounding Kacchan’s temporary death, which was to be expected. Enough tears to fill an ocean were shed, a touch of anger erupted during heated arguments (how dare Kacchan leave him? Rest assured, that anger had dispersed quite quickly), but the occasional joke was also cracked. Using gallows humor to cope with the trauma from the job was pretty well-researched by Hero psychologists, the same way that EMTs had been doing for centuries. Much to everyone’s surprise, most of the jokes had come from Todoroki. Izuku had suspected that they probably weren’t meant to be jokes, but they had just come out like that, and even more surprisingly, Kacchan always laughed at them. Only from Todoroki, though – Kaminari tried once and had his door blown off for it. So, Izuku knew what Kacchan could handle.
Just as predicted, Kacchan hadn’t been able to feign his anger for long. His bottom lip wobbled pathetically, not holding back tears, but in his failed attempt to suppress a laugh.
The room filled with the sounds of giggles erupting from the pair. Izuku basked in that moment for a while; the bright, boyish smile on Kacchan’s face akin to the one that was broadcast to the world when All Might gave him the gauntlet. His stunning ruby eyes glistening with joy and raw love. The faint throbbing of Katsuki’s pulse on Izuku’s skin serving as the loud reminder that he was alive.
It was beautiful. Kacchan was beautiful.
Carefully, Izuku began undressing Katsuki from his yukata (yes, he had been paying attention about how to take it off). His scar-painted fingers worked methodically to unfold the sleek flat obi belt that had tightly found purchase around Katsuki’s waist, and their hips met momentarily when Kacchan raised his pelvis to assist Izuku with the bow around his back. Both of their breaths hitched as their groins brushed up against each other.
Once the obi was untied, Izuku focussed his efforts on removing the stunning yukata Kacchan had donned. He tenderly opened up the folds of the material and his hands made themselves at home around Kacchan’s generously padded trapezius, admiring every single twitch and bump underneath his fingertips. Viridian eyes locked onto the faint starburst scar on his lover’s shoulder – the bittersweet reminder of where they came from, how he might not have been so lucky. A soft kiss was pressed to the scar, so delicately as if Kacchan was made of glass. A breathy moan left Kacchan’s lips as he tilted his head back, exposing more of his neck to Izuku.
Katsuki leaned into Izuku’s touch as he removed the yukata fully, and Izuku allowed himself a moment to truly bask in the sight of the body laid beneath him. Vulnerable, wholly trusting of Izuku. Kacchan’s body was almost oxymoronic, Izuku thought to himself. A beautiful contradiction. Every muscle was sculpted out of marble, every inch of flesh perfectly chiseled, and each pale scar told the story of his many battles. A warrior, a Hero, a true image of victory. And yet, the slim waist enunciated all of his roiling muscles beneath Izuku. Kacchan’s supple porcelain skin was so soft that it made Izuku wonder if he was touching clouds. He was angelic, looking up at Izuku with soft, crimson doe eyes as if he had held the entire world right in front of him.
Izuku couldn’t wait to devour this man and turn him into a writhing mess.
His lips latched onto a sensitive spot on his neck that he knew would drive Kacchan crazy, and as predicted, a small hum could be heard seconds later. Izuku nibbled before pressing his tongue flat on the surface to soothe the bite mark. He continued to trail sensual kisses to his boyfriend’s tender neck, mouthing over his jaw and Adam’s apple, earning a low purr from the back of Katsuki’s throat. The noise was electrifying. Izuku pressed an intricate series of feather-light kisses to the collarbone and drew more hitched breaths from the blonde.
He sank lower down the bed and down Katsuki’s body, nipping and licking and biting every part of his smooth skin, paying particularly close attention to those pecs that Izuku adored so much, before finally coming face-to-face with the scar his lover received from Shigaraki. Izuku’s palm was so wide that it nearly covered the entirety of it. It was known to still be a bit tender for Kacchan at the worst of times, but it couldn’t be ignored. It shouldn’t be ignored – it’s not an ugly, torn piece of flesh to be hidden away from the world. It was solid proof that Katsuki Bakugou fought against Tomura Shigaraki and All For One and lived, because there was nothing that Kacchan couldn’t do. Flat palms brushed up and down his firm obliques, the rise and fall of Katsuki’s chest increasing ever so slightly at the new sensations. A set of fingers found themselves tangled in Izuku’s curls as he littered the scar with kisses more gentle yet more passionate than he ever had done before. His efforts ushered a soft hiss; Kacchan was becoming undone and Izuku had barely even gotten started.
Before sinking lower down his body, Izuku took a moment to swipe his thumbs over Katsuki’s nipples, being rewarded with a small mewl. Izuku always did have a soft spot for Kacchan’s chest.
Izuku’s fingers slotted into the dip in Katsuki’s hips, darting his eyes upwards for a moment.
“I’m sure I saw you put underwear on when we got dressed earlier,” Izuku said, slightly confused. He wasn’t complaining, though – the thought that Kacchan was naked under his yukata the entire time made his cock throb again.
“Took ‘em off before we left,” he replied, a smirk tugging at his lips. “Was feeling traditional.”
Strong hands pulled Izuku upwards as Katsuki bolted upright in an instant, capturing his lips in a deep and heated kiss. As Izuku cupped Kacchan’s face affectionately and his tongue brushed his lips, Katsuki’s hands were going to work on the green yukata Izuku was wearing. That familiar warmth pooling in his abdomen spread across his entire body as his tongue lapped into Katsuki’s mouth.
“Getting impatient,” Katsuki murmured into the kiss, throwing the mound of clothes onto the hotel room floor and yanking Izuku’s boxer shorts off. “You were wearing too fucking much.”
Izuku wanted nothing more than to let Kacchan continue to manhandle him, but he had insisted that he wanted to make Kacchan feel special tonight, and he was dead set on doing that.
With a forceful shove, Katsuki fell back onto the bed with a thud, his eyes widening with anticipation. He placed either hand underneath Katsuki’s knees, pulled them up, and then spread them wide, giving Izuku a glorious view of his cock and asshole, and he was certain for a moment that he had just drooled. Kneeling in between his legs, Izuku perched himself neatly on his knees at eye-level with Kacchan’s cock. Their gazes locked again and the sheer feral need lit a fire inside Izuku, maintaining that intense eye contact as he dipped the tip of his tongue out between his lips and licked a bead of pre-cum from the head of Katsuki’s cock. It appeared as though Kacchan was biting his lip to suppress a moan, and Izuku wasn’t having any of that.
His tongue trailed around the head of Katsuki’s cock, lapping at the slit hungrily as his mouth was acclimating to the bitter fluid left on his taste buds. Even now, it was still one of the best things Izuku had ever tasted. He flattened out his tongue and slowly, teasingly, licked up the entire shaft, starting from the base, feeling every thick vein under it, and flicked the tip again once he’d reached it. Kacchan had started breathing more rapidly, but that still wasn’t what Izuku wanted.
In one swift movement, Izuku swallowed the entirety of Kacchan’s cock, and his boyfriend let out a long, breathy groan. Bingo.
Bobbing his head up and down Katsuki’s thick shaft in a sloppy rhythm, Izuku worked his hand around the base of his cock agonizingly slowly and the room filled with soft, whiny moans that were music to Izuku’s ears. His vision blurred slightly with tears every time the head of his cock hit the back of his throat, but the burning feeling was exquisite. Izuku hummed with enthusiasm into every dip of his head, his own abdomen pooling with heat with every moan that escaped Kacchan’s lips. The fingers that had found themselves tangled into his curls encouraged Izuku to deepthroat him again, leaving a long string of saliva from his lip to the head of Katsuki’s cock when he retreated for air.
“Fuck, Izuku,” Katsuki panted, one hand cradling Izuku’s jaw to entice him to look up and face his boyfriend. The reverence in his face alone could’ve been enough to push Izuku over the edge. His thumb ghosted over Izuku’s lip to wipe away the remaining saliva, only for Katsuki to dip his thumb in between his lips after. Izuku sucked on it obediently, swirling his tongue around it. “You are so fucking hot.”
Izuku didn’t verbally respond – only dropping the thumb from his mouth to suck a bruise onto the inside of his lover’s thigh, nibbling sweetly and then kissing his handiwork after. He repeated this a few times across both thighs and Katsuki threw his head back into the pillows with a strangled growl.
Both of Izuku’s hands then cupped each of Kacchan’s ass cheeks, fingers digging deep into the soft flesh and spreading them apart to the best of his ability while Katsuki was on his back like this. His warm breath on Katsuki’s hole made the man twitch below him. It looked delectable, and the serene expression on Kacchan’s face only continued to stoke the fire inside Izuku. That being said, he couldn’t be sure how Kacchan would take to being eaten out – he’d only just managed to convince Kacchan to bottom for once. Baby steps.
Still, Izuku couldn’t resist the temptation to swiftly flick the hole with his tongue, before sitting upright. The high-pitched, un-Kacchan-like whimper that echoed in Izuku’s ears following his taste made his head go fuzzy for a moment.
“Lube?” Izuku asked breathlessly.
Kacchan reached over the bed to retrieve the lube that was in their overnight bag, his body stretching perfectly to give Izuku a breathtaking view of his torso and abs. Izuku would never grow tired of staring at Kacchan’s body, admiring the years spent toning his muscles to be able to withstand his quirk. His throat was suddenly very dry, but he was snapped out of the daze when the bottle was ungracefully thrown into his lap, a set of piercing ruby irises staring at him expectantly.
Unless anything had changed in the past week, Izuku knew that Kacchan hadn’t experimented with anal play on himself before, so he had to take things slow. He squeezed a sizable puddle of lube onto his palm and generously coated his fingers, pressing the tip of his index finger against Katsuki’s hole. Kacchan jumped ever so slightly at the contact – or maybe because the lube was still cold; Izuku hadn’t left it in his palm long enough to warm it up. Oops.
“Are you ready?” Izuku asked sweetly, massaging his entrance in slow circles.
Katsuki replied with a grunt and an impatient roll of his hips.
Izuku pressed the first finger in slowly, earning a startled gasp from his boyfriend, as Katsuki bit down on his lip. He waited for a moment for Katsuki to adjust before setting a steady rhythm, pumping his finger in and out of Kacchan. Once it was moving with less resistance, he added a second finger and increased the pace.
“Izuku…” Katsuki whined breathlessly, his brows furrowing as he fucked himself on Izuku’s fingers. “Fucking more.”
“You’re doing so well, Kacchan,” Izuku cooed, pressing a wet kiss to the inside of Katsuki’s thigh – which earned another guttural moan that went straight to Izuku’s cock. “Just a bit more and then I can give you what you want. Keep going, that’s it. You’re doing so good.”
The idea that it was Izuku who was pulling such filthy sounds from Kacchan was enough to make his own cock painfully throb – almost hotter than the fact that he was already two fingers deep inside him. A few strands of Katsuki’s sandy blonde hair were stuck to the sweat beading on his forehead, and his lust-blown eyes had not left Izuku, piercing his very soul. Becoming impatient himself, he added a third finger slowly, watching as Kacchan writhed around with the bedsheets firmly in his grasp. Izuku wondered if he was going to tug on them so hard that they would rip under his raw power.
Izuku suspected he’d hit that sweet spot when Katsuki all but screamed his name, trying (and failing) to match Izuku’s rhythm with his hips with much more vigor than before. That sound alone could’ve been enough to make him cum right there and then, removing his free hand from Katsuki’s thigh to squeeze the base of his own cock.
They’d never last like this. It was now or never.
Without any warning, Izuku removed his fingers from Katsuki, who let out a pathetic whine at the sudden emptiness. He’d opened his mouth to spit out a bitter retort about the loss, but Izuku beat him to it.
“Kacchan looks so pretty around my fingers,” Izuku preened, trailing sloppy kisses up Katsuki’s inner thighs before putting his hands atop the blonde’s knees. “But he’s going to be even prettier around my cock.”
Izuku slid his hands to the underside of Katsuki’s knees and heaved, almost bending his boyfriend in half beneath him, as he flicked a rose-tinted nipple with his tongue. It earned a shiver from his boyfriend. Before letting himself get too distracted by Kacchan’s body – he really could worship it for hours, if Kacchan would let him – he sat himself upright, aligning his lube-slicked cock against Katsuki’s hole. “I’m going to take it slow for you, okay Kacchan?”
“Ugh, would you just fucking hurry up–”
If Izuku knew it was this easy to wipe that smug smirk that was permanently seated on Kacchan’s pretty face, he’d have asked to fuck him a long time ago. Izuku slowly pushed into Katsuki’s suffocating heat, watching as his eyes widened more and more with every inch, until Izuku had bottomed out inside of him.
“Mmm… so tight, Kacchan,” Izuku gasped and remained still for a few moments to let his boyfriend adjust. He meant what he’d said earlier about Kacchan looking beautiful around Izuku’s cock, but the images in his mind’s eye were nowhere near as breathtaking as the real deal. His cheeks were flushed a violent scarlet, the sweet scent of nitro-sweat already overloading Izuku’s lungs, heat radiating off him, overloaded with Kacchan.
He pulled out slightly, just enough to roll his hips back into Katsuki with a soft thrust. The sensation was everything that Izuku could have hoped for and then some, a low “fuck” escaping his throat as he was consumed by Kacchan again. A slurred string of profanities also left his boyfriend’s mouth.
“Ngh… f- fuck, Izuku,” Kacchan whimpered as Izuku repeated his movement; pulling out until just the tip was inside him, then slamming back inside at just the right spot to make Katsuki’s legs tremble around Izuku’s hips. “Ahh, harder, faster, fuck–”
“Kacchan takes me so well,” Izuku moaned as he picked up the pace, driving in with more force. The motions and the pleasure were both familiar and foreign. It was like getting the hang of Full Cowling for the first time; something that came naturally when he turned his brain off.
He wasn’t sure if it was overwhelming pleasure or if it was Izuku’s words, but Katsuki threw his arm over his eyes and let out a lewd mewl from his throat. His cheeks were getting heated again, almost rivaling the shade of red in his eyes.
Izuku leaned down, locking Katsuki’s legs between them. He folded so well. He kept his balance on one arm, continuing to drag his cock out of Katsuki’s tight hole and slam it back in, and grabbed the arm strewn over his boyfriend’s face. He threw it over Katsuki’s head and pressed into the pillows. “I want to see your face and hear your voice while I fuck you. You make the most beautiful faces and noises.”
Another broken noise came from Katsuki at that, his eyes flying open. Those gorgeous, carmine irises locked onto Izuku’s, while his chest rose and fell with short breaths. He looked utterly debauched like this, and it was was fucking phenomenal. Izuku dove down to capture Katsuki’s lips. The kiss was short, but wet and needy, Kacchan moaning into his mouth. Izuku was fucking Kacchan so hard, drool was pooling under his tongue like a dam about to burst.
“Holy shit, Izuku, fuck, fuuuuck–” Kacchan’s words quickly became unintelligible with every thrust, and Izuku pressed a series of open mouth, wet kisses to his boyfriend’s damp neck. He nibbled slightly here and there, the vibrations from Kacchan’s moans encouraging him further.
Izuku pulled back, releasing his grip on the wrist and letting it trail along the arm and down the body. He cooed to his lover, “I knew you would be so good for me. So tight. Oh my god. I won’t be able to last very long. You are so pretty, all unraveled under me like this. You’re going to cum for me without even touching yourself, isn’t that right, Kacchan?”
Katsuki gave a fervent nod.
Izuku readjusted Katsuki’s knees so they were thrown over his shoulders. His hands found purchase on that small, tight waist, his fingers almost touching. He picked up the pace even more, using the new angle and the grip to his advantage.
The slapping of skin on skin and the squelching of lube was obscene, but it had nothing on the noises coming from Kacchan. Especially the scream when Izuku’s cock found the perfect spot. The cried pleas of Izuku please intermingled into obscenities. Kacchan didn’t beg often. His neglected cock was hard and red, the precum-wet tip leaving trails on his hard abs. His whole body shone with sweat from the workout. The sight and sounds of Kacchan actively coming apart pushed Izuku nearer and nearer to the edge.
He dared a glance down to where they were connected, where Izuku’s cock breached Katsuki’s hole, where his balls hit the pale ass. It was surreal to watch the stretch and shrink of Katsuki’s hole along the contours of Izuku’s cock while it pushed in and out.
Izuku turned his head to the side, dropping open mouth kisses on the toned leg and knee on his shoulder. One of his hands released Katsuki’s waist and trailed down his hip and up the thigh. Izuku dug his short fingernails into the meat of the leg. “I want to watch Kacchan cum around my cock. Will you be a good boy and do that for me?” he asked, focusing back on Katsuki’s face. He emphasized his statement with rapid thrust of his hips, aiming right for the prostate.
As if he had been waiting for permission, Kacchan tensed up and arched his back, throwing his head back into the pillows with a delicious deep groan. It might just have been the hottest noise Izuku had ever heard in his life. His untouched cock twitched as it started to spurt short white ropes on his abs and chest.
But then in the illumination of the fireworks festival, Kacchan became his own fireworks display. Starting from the hands that gripped the bedsheets, then up his arms, and then his whole body, the sheen of sweat that coated Kacchan’s skin ignited in small pops of micro explosions. Izuku almost went still as he watched the majestic sight of his boyfriend beneath him, but he continued to drag out the majestic orgasm with slow but deep thrusts. The waist and thigh under his hands, and the legs wrapped around his shoulders were the next to spark. The explosions weren’t large enough to hurt, but the heat of them was sensual on Izuku’s sensitive, aroused skin.
Even with the massive bursts of reds, greens, golds, pinks, blues, and coppers right outside their hotel window, Izuku’s eyes could not focus on anything but the beautiful, ethereal sight of his boyfriend writhing, cumming, and exploding beneath him and around him.
Izuku didn’t know it was possible for him to fall even more in love with Kacchan, but he did always surpass all expectations.
The sight, mixed with the sensation of being inside Kacchan, was enough to send him over the edge. He gave one more thrust, pushing as deep as he could before he came inside him. “Kacchan is so beautiful,” he moaned, leaning down again to press his lips against Kacchan’s. This kiss was slow and exhausted while Izuku rode out his own orgasm.
When he felt his dick stop twitching and start to soften, Izuku unmounted Katsuki’s legs from his shoulders. The new space allowed Izuku to lay on top of his boyfriend, and while he knew he could take his muscle dense body weight, Izuku still propped himself on his bent elbows. He felt the wet of Katsuki’s spent smear onto his own chest and stomach with this new position.
“You felt amazing,” he murmured and rubbed his nose along Katsuki’s cheek.
Katsuki grunted in response, avoiding eye contact. His arms were still taut as he kept a grip on the bed sheets.
They basked in silence for a minute, until Izuku felt himself slip out. Katsuki gasped, one hand finally letting go of the sheets to dart between his legs. “Shit, Izuku. Is this what you always have to fucking deal with?”
“What do you mean?” Izuku pushed himself up to study Katsuki’s face.
Katsuki rolled his eyes. “I feel fuckin’ empty. And all your jizz is seeping out and it’s fucking gross. Did One For All give you the ability to spunk buckets along with the strength and extra quirks?”
Izuku laughed. “Sorry, Kacchan. If it makes you feel better, that’s what it feels like for me too. Let me clean you up. Be right back.” He rolled off Katsuki and sat up. With one more longing glance at a wrecked Kacchan laying on the bed, and a quick note at the singed marks in the shape of Katsuki’s fingers on the sheets, Izuku got off the bed and padded to the bathroom. He’d have to be sure to tip the housekeepers an extra ¥5,000 for the damage to the bedding.
He turned the faucet on hot and allowed the water to heat up while he grabbed two washcloths. He wet the first one and almost felt begrudged to remove the marks of Kacchan’s cum and the lube on his cock. When he was unfortunately clean, he wet the second washcloth and went back to Katsuki who was lying in the same position Izuku left him in.
In the dark room, with the only lighting the finale of the fireworks display shining colors throughout, he could still see the clouded look in Kacchan’s eyes as he started to withdraw. The one hand still tangled itself in the mangled sheets in the aftermath of his bliss. Izuku kept studying his features and methodically wiped at his chest and stomach. Then he focused on cleaning his cock, ghostly lightly along the tip, just enough to clean but not to not overwhelm Katsuki’s post-orgasm senses.
Finally, he dragged the washcloth to Katsuki’s abused asshole. He could see it still flexing as if it was still adjusting to emptiness. He cleaned up the stray lube and the leaking cum, resisting the urge to fit a washcloth-covered finger back up there to start the cycle over again. To see those fireworks again… Izuku would’ve given the world.
When Katsuki was as clean as a damp washcloth could fix, Izuku leaned down and pressed a kiss to each of Katsuki’s cheeks, forehead, and then finally his lips. “Love you, Kacchan,” he murmured.
A sheepish, “You too,” was Katsuki’s grumbled reply.
Izuku retreated to the bathroom to toss the used washcloth with the one he had used earlier. Then he returned to his dear Kacchan, he found Kacchan perched on the bed, facing away from him with his head in his hands. “Kacchan, what’s wrong?”
“I didn’t hurt you, did I?” Kacchan replied quietly, turning to face Izuku reluctantly and oh, the broken expression on his delicate features made Izuku’s stomach knot.
Perching himself on the bed beside his boyfriend, Izuku wrapped an arm around his slender waist and pulled him closer. His brows knitted together in concern as he said softly, “No, Kacchan could never hurt me.”
“What the fuck was that?” Katsuki snapped, a hint of bitterness in his tone, but Izuku knew the bitterness was not directed at him. “I have perfect control over my quirk, I don’t know why that fucking happened. I could have hurt you, Izuku.”
Izuku used his scarred hands to shift Kacchan so that they were facing each other now, not allowing Kacchan the opportunity to emotionally cut himself off by avoiding eye contact. He couldn’t let Kacchan shut him out like that. Izuku had spent too long trying to knock down the wall that he had built. “But you didn’t hurt me. Like I said, Kacchan could never hurt me.” He brought up a hand to cup his boyfriend’s cheek, softly rubbing it with his thumb, and Kacchan leaned into the touch. “I’ve read that it’s not unusual for somebody to lose control of their quirk during sex, and if you’ve never experienced prostate stimulation before, of course it might have been overwhelming. Especially since your quirk is focused around sweating, and we were building up quite a sweat back there. And now since you can create explosions from anywhere on your body, not just your palms, the chances of–”
“Mumbling, nerd.”
“R-right,” Izuku chuckled awkwardly before locking eyes with Kacchan’s. “The point is: you’re not failing, or broken, or anything like that. What happened was normal. You didn’t hurt me – I actually really liked the feeling of them on my skin.” Kacchan’s eyes widened a miniscule amount at this admission, so little that any regular person might’ve missed it. But Izuku knew Kacchan better than anyone. “And you looked so beautiful like that, lighting up like my own personal fireworks display. I didn’t think it was possible for Kacchan to get any prettier.”
“Tch.” Kacchan attempted to put on a brave, nonchalant front, but his cheeks flushing had given away his true feelings, as he buried his face into the crook of Izuku’s neck. “Soppy bastard.”
“I love making Kacchan feel good.” Izuku planted a kiss on the soft, but slightly damp, blonde spikes, nuzzling into them. Katsuki threw an arm around Izuku’s waist, and Izuku mirrored the action, squeezing him tight. “I love you, Kacchan.”
“I love you, too, Izuku,” Katsuki mumbled against his neck, lips brushing his throat.
And they fell asleep in each other’s arms. Izuku drifted off, floating on cloud nine, grateful for this new, exciting step they had taken in their relationship. He was shy to admit that he rather enjoyed the new dynamic, and he hoped Kacchan did too.
The next morning, Izuku rose gently to the sunlight through the windows. They hadn’t remembered to shut the curtains before they had fallen asleep. The alarm clock on the bedside table told him it was still really early, but Izuku felt well rested. He turned toward Katsuki who was curled on his side facing Izuku. His face relaxed, looking almost boyish in slumber.
Kacchan was not an early riser, preferring to get as much sleep as possible, but Izuku couldn’t resist leaning close and ghosting a kiss right on his cheek. He groaned, tensing a little as he woke, before opening a single, red eye to stare up at Izuku, squinting at the glare. He looked adorable, a view Izuku never got over even after months of living together and sharing the same bed. He was so blessed.
“Good morning,” Izuku whispered, smiling gently down at his beloved.
Katsuki stared for a silent minute before shutting his eye again and tossing the sheets over his head. “Too damn early. I’m going back to sleep,” he grumbled, voice even deeper than usual from sleep.
Izuku’s lower lip jutted out in a pout. “Okay, Kacchan.” He hoped his disappointment didn’t show in his voice. Usually even when it was too early for Kacchan, he still tugged Izuku close, either pulling Izuku’s head to his chest or burrowing into Izuku’s neck. His brain had shifted into overdrive, but he tried to change the subject before he started fawning Kacchan. “What time did you want breakfast? I can order room service for us.”
“Sleeping,” Katsuki bit back, a little harsher than usual in comparison to his usual morning moodiness. The tone made Izuku’s heart plummet into his stomach, but a grumpy Kacchan would not be willing to discuss it. Later, Izuku thought to himself.
Light snores came from him only a few minutes later. Izuku decided to spend the morning on his phone, messaging Uraraka about the date and scrolling through Hero news sites and forums. He sent an article to Todoroki that talked about a takedown he had done yesterday afternoon, sending his own analysis and praising Todoroki for his technique.
When the morning hit a reasonable hour, he climbed out of bed and began his day. He went to the hotel gym, which wasn’t as fancy or technical as an agency gym, but it did the job. Then he went back to his room, called room service for him and Kacchan (something that would appease him and All Might’s meal plan), and showered away the blissful memories from last night.
When he exited the bathroom, wearing only a pair of shorts and toweling his hair, Katsuki was awake. Room service must have arrived in the few short minutes that Izuku showered and woke him up. He was sitting at the bedside chair where Izuku had placed the All Might plushy the night before, picking at a fish with his chopsticks.
“Good morning, Kacchan,” Izuku said for the second time that morning, trying to make his words sound as happy and sincere as possible. He wasn’t entirely sure that it worked, though.
Katsuki glanced up from his breakfast to take in Izuku for all of three seconds, his eyes flicking up and down Izuku’s half-naked body, before his head whipped back to his food. Izuku fought a frown, especially when Katsuki only deigned a grunt in response.
Worry started to worm its way into Izuku’s gut. He knew when Kacchan got into a mood, there were two courses of action. Either he could just ignore him until the mood passes, or he could push his buttons until he snaps and finally opens up, usually in a spar or a screaming match. But now that the afterglow of last night faded, he worried Kacchan’s behavior had to do with his displeasure of bottoming, and Izuku wasn’t sure if he was strong enough to take Kacchan yelling at him that he didn’t like last night. It would hurt too much, considering Izuku learned many things.
How much he liked the dynamic. How much he liked being sheathed inside Kacchan. How much he liked making Kacchan feel good. How much he liked Kacchan cumming through prostate-stimulation, when he became a beautiful fireworks display.
Izuku placed his towel back in the bathroom and pulled up the desk chair to sit next to Katsuki. “Is this meal sufficient enough?” he asked.
Katsuki took a noisy sip of his miso soup. “Better than that junk shit from last night.” He peeked over at Izuku again, shorter than before. A flush went across his cheeks, and Izuku assumed it might’ve been anger at eating junk food.
The feeling in Izuku’s gut wove its way into his chest and heart. Kacchan couldn’t even look at him.
Izuku plastered on a fake smile that he had perfected in high school. “Well I’m glad! Thank you for the date!”
“We were only there for a little over an hour. Missed most of the fireworks.”
The smile tried to crack on Izuku. “We had a nice view from the room. Besides, Kacchan was a better sight.”
Katsuki’s eyes darted over to him, scanning his face and then sneaking lower towards Izuku’s abs. He quickly averted them again. “Whatever.”
They ate in a tense silence. When they finished, Katsuki took a shower while Izuku packed their bags and tidied the room again, his hands jittering slightly when he picked up the All Might plushy. Fond memories of Kacchan’s loud, genuine laughs filled his head, only causing the pain in his chest to spread. They had such a wonderful night… What was going on with Kacchan?
As Izuku went to make the bed, he winced when he noticed the lube had left an oily stain on the sheets, hoping there weren’t any other fluids on them as well. The scorch marks from Kacchan’s explosions had definitely burned through the comforter and onto the mattress, too – Izuku set himself a mental reminder to up the housekeeping tip to ¥10,000.
Kacchan barely said a word as they checked out or on their walk to the metro station. At least he had the excuse of politeness when they didn’t speak on the train. By the time they walked back to their apartment, the silence was stifling. Izuku’s thoughts were running a mile a minute, racing between Kacchan hating bottoming to Kacchan just hating Izuku in general now.
Katsuki’s elbow dug into his side as they approached their building, a moderate 4 story apartment complex near a small park. “You’re mumbling, nerd. I can hear the thoughts churning in your head.”
“Sorry, Kacchan. I was… thinking about upgrading my costume. Something about it just doesn’t work for me, and I can’t quite put a finger on it.” This was true. It was something that was bothering him for weeks. So he began rambling about his costume to Katsuki. He was grateful when the awkward tension between them began to evaporate as Kacchan shot off his own ideas, as if he hadn’t been giving Izuku the bare minimum all morning.
They entered their modest apartment which was furnished with cheap, mismatched furniture. The genkan was plastered in photos in clashing frames filled with pictures of them throughout their childhood and UA years. Class photos, photos of them as children as well as graduation, family pictures from their parents. It was chaotic, and Kacchan had complained the entire time Izuku hung each frame. But Izuku wanted to show anybody who entered their apartment that this was a home.
They spent the rest of their day off watching old All Might movies and documentaries, sitting on the couch with a foot of space between them. It was almost normal, similar to how they were when they had first started dating where they had to restrain themselves in the common areas.
But it didn’t ease the uneasiness that had filled Izuku.
They were back to work the next day, and the long, tiresome shifts helped ease Izuku’s mind the slightest bit. However, there was a sense of intimacy missing between them. At work, they always managed to sneak a kiss in passing, but Kacchan had begun to restrain himself from even that, flushing whenever Izuku leaned close in public. At home, the kisses were brief and limited, never enough to continue into something more. And something more devolved from a once or twice daily activity to a never activity.
Izuku supposed he was subconsciously responsible for it. He didn’t want to pressure Kacchan into doing anything he didn’t want to do. The glances he sent Izuku’s way were fleeting and almost… shy? That’s not possible. Katsuki Bakugou would never be shy. What would he even have to be shy about? It’s not like there was a big event coming up, and even that would never affect Kacchan this much.
It had to be about that night.
His mind was going into overdrive. Was Izuku just really bad at topping? Did he not prep Kacchan enough and now he’s in pain, but trying to keep it to himself? Had Kacchan hated bottoming so much that he couldn’t even look Izuku in the eye anymore? Izuku felt sick. The nausea swirled around violently as the train of thoughts came dangerously close to slipping off the tracks and setting alight at any moment.
So, Izuku shut down too. He wasn’t about to make Kacchan more uncomfortable than he already had done. Despite it breaking Izuku’s very soul, he refrained from the longing glances and stolen kisses throughout the next two days. He put on a brave smile – a Hero must always smile, regardless of what’s happening – and carried on, until whenever Kacchan felt ready to talk.
So he waited.
And waited.
And waited.
And the entire time, Katsuki barely spoke more than necessary to him. Izuku caught him looking over at him when he was sure Kacchan thought he wasn’t paying attention. This was not unusual behavior. All his friends from UA and even All Might himself all talked about the soft, yearning looks Katsuki would wear when staring at Izuku, but Izuku never noticed until they pointed it out. Then he started to feel the eyes on him, and he slowly started to pay even more attention to Kacchan, subtly watching him watch Izuku. Izuku felt so warmed when he saw Kacchan’s eyes soften and his lips curl the slightest bit.
The looks aimed at Izuku now were similar, but different. He kept staring, but never for very long. Shortly after he looked away, though, it was like his eyes were a magnet to Izuku’s pole, finding him again. The eyes weren’t as soft as they typically were, but instead more analytical, probing, dragging up and down Izuku’s body. It was soul-crushing to see Katsuki look at him like that, when he used to look at him like Izuku had handpicked every constellation in the sky just for him.
Izuku was not used to this kind of staring, and he assumed maybe it could be the start to the resolution of their weird tension. So he pushed the delicate boundaries a little. Only once. One evening, when Katsuki’s shift ended two hours before Izuku’s, Izuku came home to Katsuki preparing dinner in the kitchen, wearing sweats, a tank top that displayed his large arms, and an apron wrapped that accentuated his tight, little waist.
“Kacchan!” he greeted, salivating at the decadent smells and delicious sight. He hurried over to the kitchen, peering at the mapo tofu Katsuki was preparing, before he snuck an arm around his tight waist. He squeezed right at the base of his ribs and then leaned in for a kiss.
Katsuki recoiled, ducking away from Izuku and his hold. He turned his head away.
Well, if that wasn’t the nail in the coffin of Izuku’s heart.
Izuku broke.
It took only four days, eight hours, and about seventeen minutes of trying to give Kacchan space before Izuku couldn’t stand it anymore. He feared the future of his life might be at jeopardy if he couldn’t even fix his own relationship. But, hell – Kacchan was his life. Kacchan was his everything.
His vision blurred, and he quickly squeezed his eyes closed, swiping a hand across them. Tears always came too easy for him, and when his heart hurt so much at this tension and silent treatment, it was hard to hold them back. He dropped to the floor, onto his knees and elbows, and pressed his forehead to the cool tile between his hands.
“What the fuck are you–” Katsuki started, but Izuku interrupted.
“I’m so sorry, Kacchan!” If he wasn’t so distraught, he might’ve winced at his volume. He hoped the neighbors couldn’t hear him loudly grovel at his boyfriend’s feet. “Please forgive me!”
“Forgive you for what, you shitnerd? Get up!” Katsuki started to reach down, but Izuku forced himself even deeper into the floor, trying to express his sincerest apologies.
He also didn’t mean to start crying – sobbing, actually. The tears dripped directly onto the tile, and his breath caught in his throat with the beginnings of a hiccuping sob. “I’ve made you uncomfortable! You didn’t enjoy the sex we had, and I don’t want this to ruin our relationship. It was just an experiment, and you didn’t like it. So you never have to bottom ever, if you don’t want it.”
Katsuki heaved a sigh. It sounded like it came deep from his diaphragm, exposing the weight of his own troubles. He crouched down next to Izuku’s head, and then Izuku felt fingers in his hair. They stroked the curls for a few seconds before twining around the roots and gripping tight. Katsuki used this hold to pull Izuku’s head up and look at him.
The air felt cold on Izuku’s wet face, but the tears flowed even more when he realized that Kacchan was looking at him and maintaining eye contact for longer than five seconds. “Izuku,” he said in a low voice, dipping his head closer. “I’m fine. We’re fine.”
Izuku shook his head as much as Katsuki’s grip in his hair would allow. “Something is wrong!” he demanded. “You’ve barely talked to me since Saturday. You won’t look at me, and even when you do, it’s not the same as it used to be. You won’t touch me, and when I go out of my way to touch you, like just now, you avoid it. You haven’t even tried to initiate sex since that night. It’s like you hated it.”
Katsuki jerked his head back a little, as if surprised by the analysis. Then he glared, eyes narrowing. “You can complain all you want about sex, but you haven’t initiated it either.”
“I’m not going to pressure you into something you don’t want to do, Kacchan. Besides, I didn’t want to bring up the conversation about which one of us would top because it feels like a sore subject with you.”
Now it was Kacchan’s turn to break. His cheeks got red, but not in the same way as Saturday. This was a frustrated, angry flush. He withdrew his hand from Izuku’s hair to grab his own hair. Izuku caught his lip wobbling and the teeth catching it to stop.
“Sore subject? What, was my ass not fucking good enough? Just decided to stop touching me entirely ‘cause you’re too chickenshit to tell me that I sucked? Tch.” Katsuki growled, visibly trying hard to not yell.
Izuku felt his eyes widen of their own volition at the same time he felt something crack inside of him. Maybe it was his heart at the realization that even after two years of dating, their communication skills were horrible. Despite the newfound intimacy of living together, seeing each other everyday, and exploring each other’s bodies, they connected and expressed their deepest emotions the best when they were having some sort of fight that had been caused because of their miscommunication.
“Kacchan… of course you weren’t bad at it. You could never be bad at anything. Is that really what you thought?” Izuku felt his heart breaking as he spoke those words. Kacchan couldn’t have possibly believed that. Could he?
“You stopped fucking touching me, so yeah, forgive me for jumping to that conclusion.”
“Because you stopped touching me first! You’d been avoiding me ever since the weekend and I assumed it was about the sex we had. I didn’t want to make you feel uncomfortable, so I didn’t push anything, but if you really didn’t like bottoming or you were embarrassed about what happened with your quirk, I don’t mind–”
“Izuku.” Katsuki sighed and dropped to his knees, cupping his hands with his own clammy ones. Immediately the physical contact soothed Izuku, but not enough to stop the tears still spilling pathetically. The heat on Kacchan’s face was much more prominent now, his red irises shining even brighter with the added layer of tears threatening to pool over his lower lashline at any moment, like a dam about to burst. His expression was… unreadable. Izuku didn’t like that. “I’m gonna fucking say something, can you shut up and let me say what I need to say?”
Izuku nodded uneasily, sniffling.
“I was embarrassed, sure, but not for the reasons you said. Look, I… I didn’t hate bottoming. I – fuck – I actually really fucking liked it. A hell of a lot more than I thought I would, and I didn’t know how to fucking tell you that I wanted more of it.” Katsuki took a sharp intake of breath, albeit shaky, his thumb rubbing over the scars on Izuku’s hands. “Ever since that night, I saw you differently. Dammit, not in a bad way – the complete opposite. Seeing you like that was so hot, I was almost too fucking shy to touch you after that. I ain’t some dumb teenage girl with a crush, I feel pathetic. But also, I…”
“You got in your own head thinking I’d see you differently. You were vulnerable, and you thought I’d think badly of you because of that.”
“Didn’t I say not to fucking interrupt me?”
“Kacchan,” Izuku sobbed loudly, pulling Katsuki into an aggressively tight hug as the tears continued to stream down his face. “You’re the strongest person I know. There is not a single thing on this planet that could make me think badly of you.” He pulled back to cup Katsuki’s face in his hands, his thumb ghosting over the scar across his cheek. “I wish you’d have told me that you liked it, but I know that this is just how you work. I’m flattered that I fucked you so hard you became shy around me, but I never want you to feel weird around me, ever.”
It was clear to Izuku that Kacchan was holding back a defensive remark at the last statement, but he had chosen to remain silent. His features softened and most of the heat from his cheeks was starting to dissipate.
“If… if you really want me to top more often, you’ve got it. You’ve got all of me, forever. However you want me, I’m yours, Kacchan. Always have been.”
Kacchan was obviously trying hard to avoid shedding any tears, but the way his face was crumpling indicated that Izuku had hit the nail on the head. He only responded with a few shaky breaths, his eyes flickering over Izuku’s face like he was looking for something more.
“I meant what I said that night. Your explosions… they were the most beautiful thing I’ve ever laid eyes on,” Izuku continued, a nervous smile growing on his lips as he spoke the next few words. “And besides, I kinda… maybe have a quirk kink. Even if you start being able to control your explosions during sex, I don’t think I want them to stop.”
In a second’s notice, the dam had burst and their lips collided together desperately. Katsuki kissed Izuku with a fervent need, his warm hand gripping the nape of Izuku’s neck to pull him so close to Kacchan that he could barely breathe.
“Izuku,” Katsuki gasped, pulling apart and staring intensely at Izuku, so close that their foreheads were nearly touching. “I want you to fuck me.”
Izuku nodded enthusiastically. “Okay.” His voice was almost inaudible, the sound barely able to escape his choked up throat. “Okay,” he repeated louder. “I want that too.” He leaned in for another open mouthed kiss.
The sound of sizzling made them pull apart. “Fuck,” Katsuki muttered. His eyes flicked between the stove and Izuku, and Izuku could see the desperate need and want in them. Their dinner gave a bubbling noise as the sauce reached boiling temperatures.
Izuku stole Katsuki’s lips with his own to ease his worries. “It’s okay, Kacchan,” he whispered against those kiss-swollen lips. “We’ll turn off the heat and then eat it after I’m through with you. Sounds good?”
Katsuki gave a tiny nod, closing his eyes briefly. They rose from the floor together, and Katsuki turned off the burner, moving the pan onto an unused one and covering it with a lid. While he did that, Izuku came behind and wove his arms around the waist emphasized by the tightly knotted apron. He perched his chin on Katsuki’s shoulder, watching his slender hands complete the tasks at hand.
When he finished, Katuski began to turn in Izuku’s arms, but Izuku literally swept him off his feet with an arm at the back of his knees and one at his back. Izuku regarded his boyfriend with a smirk when he used both hands to hide his face from the red hot flush that consumed his cheeks. Izuku hummed. “I should princess-carry you more often, Kacchan. I like holding you like this.” Izuku padded across the living space to their bedroom.
“This is the only fucking time I’m going to allow this shit,” Katsuki said, but the growl he typically relied on to for threats was replaced with a higher voice, like he couldn’t chose between embarrassment or excitement.
Izuku crossed the small space to their bed before unceremoniously tossing Katsuki lightly. “What if it means I’m carrying you off to fuck you?” he asked, eyelids falling to half mast as he took in the blonde. He climbed onto the bed slowly and prowled up Katsuki’s body.
Katsuki bit his lip. “I could be swayed.” His piercing gaze followed Izuku’s every move. Izuku felt like they were predator and prey, but he couldn’t tell who was actually the predator and who was the prey with the look that Kacchan gave him.
When he was fully atop Katsuki, he quickly learned who was who. Kacchan struck like a viper, using one hand to shove Izuku’s shoulder. Izuku toppled, more surprised than anything. Kacchan took advantage of the new position, jumping on top of Izuku.
Straddling Izuku’s thighs, Katsuki desperately threw off his apron and t-shirt, and bent down to press a set of wet, open mouthed kisses to Izuku’s neck. With his tongue he trailed down the shell of Izuku’s ear, earning a shiver.
One of Katsuki’s hands slid underneath Izuku’s post-work t-shirt, and Izuku was anticipating to feel the familiar warmth on his chest or abs, or a teasing flick of his nipple. Instead, Izuku’s nose was flooded with the smell of burnt fabric and smoking nitroglycerin, as the t-shirt fell off his body in a charred mess.
Izuku wished he told Kacchan about his quirk kink much sooner, because this was delightful.
Kacchan worshiped Izuku’s chest as though it were royalty, licking strips of his abdomen like it was his last meal. Every little butterfly kiss and kitten lick went straight to Izuku’s cock – just when he realized how much he was enjoying being the victim of Kacchan’s starving affections, another warm hand reached down Izuku’s boxer briefs and burnt them off in an instant.
When Izuku’s pants were scraps flung across the room, Izuku’s cock brushed right in the valley of Kacchan’s defined pecs and it made it unceremoniously twitch even harder between them.
Katsuki suddenly put himself level with Izuku’s pelvis. Izuku combed a hand through the blonde spikes, sitting up on his elbows for a moment. “What are you planning on doing, Kacchan? I wanted to make you feel good.”
Kacchan looked up through his lashes, a scandalous sight. He gave a wicked grin full of teeth. “I wanted to try something out on you.”
And then without warning, he completely took Izuku’s cock in his mouth, consuming it wholly. Izuku gasped when he felt his tip hit the back of Katsuki’s throat. “Kacchan!” he shouted. He could feel that wicked curl of the lips at his base as Kacchan proved his skill. The gags he gave felt more like moans than his gag reflex.
Katsuki bopped up and down, from the very tip to the very base. His hands stayed firmly latched on Izuku’s thighs, to both keep his balance and give him leverage but also to keep Izuku from thrusting his hips up.
He pulled himself off, breathing heavily, and laved his tongue along the tip, right over the hole, and the underside, right along a vein. Izuku couldn’t stop the moan that came from deep in his throat. Izuku threw his head back, trying hard to not move his hips. Katsuki went back to taking the whole cock in his mouth and deepthroating, and Izuku couldn’t decide which one felt better. The teasing right at the more erogenous area of his cock, or the feeling of the hot, wet mouth suctioning around him.
And then the most amazing thing happened. Izuku found another incredible feeling of receiving blowjobs, and honestly it might have been his favorite.
He felt little pops along the whole shaft of his cock while Katsuki had him deep inside his mouth. They hurt in the smallest way, the most pleasurable type of pain. They came from everywhere sporadically, on top, his tip, the underside.
Izuku gave an audible gasp at the realization. “Are you using your explosions in your mouth right now, Kacchan?” he exclaimed, peering down to make eye contact with Katsuki, but ended up throwing his head back into the pillows with another guttural moan.
Katsuki responded with a smug hum around Izuku, and within seconds, the two hands latched onto his thighs began to crackle and smoke. The explosions were controlled with an extreme precision; not hot enough to cause any serious pain or lasting injuries, but enough to enhance the sensation of the blowjob and make Izuku’s heart miss a beat. This pleasure was so good that Izuku could feel it in his veins, and if he weren’t trying his hardest to refrain from cumming there and then, he’d be analyzing Kacchan’s temperature control like the damned nerd that he was.
“You’re s-so good, Kacchan. Feels amazing,” Izuku praised through broken moans as Katsuki set off another round of microexplosions around his cock. A well-aimed explosion cracked on Izuku’s frenulum, inciting another lewd scream. “I’m not gonna last like this.”
With an obscene pop, Katsuki let go of Izuku’s cock and thighs, stood up to take his pants off, and then threw himself on the bed next to Izuku. His blush-tinted cheeks and swollen lips were bordering on pornographic, especially with the way he stared at Izuku like he’d hung the entire moon for him. Izuku just couldn’t take it.
He stole a wet, sloppy kiss from Katsuki, teasingly biting down on his bottom lip, before sitting upright onto his knees. “On your back.”
Katsuki complied and Izuku reached for the bottle of lube on the nightstand that had been untouched for nearly five whole days. He opened the cap and squeezed some onto his fingers, rubbing them together to warm it up.
“Izuku?”
Izuku glanced up at the soft, timid sound of his name. “Yes, Kacchan?”
Kacchan tipped his head back to avoid eye contact with a pretty pink flowing from his face down to his shoulder and chest. “Last time, you…” His words faded off, and his hand ran down his face while the other one gripped the sheets. “You did something that I really liked.”
Izuku put his clean hand on Katsuki’s thigh, tracing gentle patterns with the tip of his fingers. He liked watching Katsuki’s cock bob at his touch. “What did I do, Kacchan?” he asked. His voice was low, almost a purr. He was excited that something he did last time was good enough that Kacchan wanted to do it again.
“You licked me. My ass. I liked it, and I want more.” A hard swallow with an audible gulp echoed in the room. “Please.”
Izuku froze at this confession. Never did he think that Kacchan would be asking to be eaten out. He even restrained himself last time because he had been so sure it would be too much for him or turn him off.
He felt his head nod as if it were disconnected from its body. He kept nodding and muttering, “Okay. Okay. Okay. Yeah. I can do that. Okay.”
“Izuku,” Katsuki said, his voice firm, but embarrassment still evident. “Less muttering and more tossing salad.”
Izuku widened his eyes, and then he grabbed the pillow that was unoccupied by Katsuki’s head. He had never personally eaten anyone out, but he and Kacchan had done experimenting with himself as the subject, and now he had to rely on that experience to lead him. He lifted Katsuki’s hips with the hand slick with lube and threw the pillow underneath with the other. He gave a quick nod when Katsuki settled back down with his hips at the perfect angle.
Then he went onto his belly between those slim but strong legs, blinking up once at his beautiful boyfriend from around his beautiful cock. “I love you, Kacchan,” he whispered. “Let me know if you need me to stop.”
Katsuki maintained eye contact. “I don’t think you’ll need to.”
Izuku smiled. “Let me know anyway.”
And then turned his face to between Katsuki’s legs. The thick cock stood tall and proud, red and twitching with anticipation. Beneath that hung a heavy ball sack. Izuku gave it a test lick. Katsuki swore at the contact, and it encouraged Izuku to run his tongue along them and between them, along that sensitive crease.
Kacchan’s filthy moan ingrained itself in Izuku’s brain. It was something he would replay for the end of time.
He moved his tongue lower, to the underside of the scrotum, sucking a ball into his mouth. Then he went even lower, quickly tracing over the perineum. The mewl Kacchan let out had him backtracking, licking, kissing, and sucking that small area of skin between his balls and his hole. Katsuki’s hands noticeably gripped the sheet tighter, straining at the sensation.
Despite the obvious pleasure from Izuku stimulating that one spot, Katsuki wove a hand in his hair and pushed his head down. “Lower,” he demanded, sounding like an outright bossy, needy slut. Izuku complied though because his goal was always going to make Kacchan feel good and feel loved.
He finally reached the asshole, the puckered skin practically begging for his attention. He flattened his tongue and gave a full lick along the hole, getting Katsuki nice and wet. Katsuki cursed loudly at the action, and his balls and cock both bopped. Izuku took that as a sign to continue.
He circled his tongue around the hole, licking at every little crease and fold of skin. Izuku knew from experience how sensitive just the outside of the hole could be without any prostate stimulation. He moaned at the idea of Kacchan cumming just through this, and in turn, Katsuki moaned at the added vibrations.
Izuku pressed himself deeper, moving his tongue and chin over places his mouth couldn’t reach. He used his clean hand to reach under Katsuki and spread one cheek apart, giving him more room to fully satisfy him.
When he determined Katsuki was slick enough, he used the hand with the lubed-up fingers and slid a single finger into the hole. The combination of Izuku’s spit, plus the remnants of lube and Katsuki’s own stimulation, allowed the finger to easily slide in. Izuku continued to run his tongue along the folds around the hole or the perineum. Kacchan continued to make the lewdest of noises, unable to restrain himself.
Izuku added a second finger, and even with the tight stretch of the hole, it went in almost as easily as the first. He thrust the fingers in and out at a slow place, spreading them and scissoring the hole to allow it to expand and loosen. With the wider opening, Izuku darted his tongue inside, squeezing it next to his fingers and lapping at the inside of Katsuki’s hole.
“Fuck, Izuku,” Kastuki moaned whorishly. “You’re getting me close.”
Izuku smiled, pressing it into Katsuki’s skin, letting him feel the rare wickedness. He continued to tongue and finger fuck the hole, searching for the sweet spot. He replaced his tongue with a third finger, continuing to spread them to open him up even more.
Katsuki grabbed Izuku’s hair, yanking at the roots close to the scalp, pulling his face away from the beautiful asshole. Izuku peeked up at Katsuki. His cheeks were a vibrant scarlet and eyes shiny with wide, blown out pupils, overwhelming the red. “You need to fuck me right now.” He bit his lip and moaned as Izuku kept thrusting his finger. “I need more. I need you inside me.”
Izuku gave a sweet smile and extracted his fingers gently. “Okay, Kacchan. Would you like to put lube on me?” He held out the lube bottle in question.
Katsuki quickly shot out a hand and snatched it. He extended his other hand upside down and crooked a finger at Izuku. “Up,” he simply said.
Izuku pushed himself out of his prone position and crawled up Katsuki’s body, sitting himself on the narrow hips. Katsuki squirted cold lube directly on Izuku’s cock – now dry after the blowjob. Izuku winced at the temperature, and then jumped when Katsuki’s warm hand clasped around it, stroking to spread the lube along his erection.
When Izuku was sufficiently coated, Katsuki removed his hand and patted Izuku on the cheek with the same one, leaving a handprint of lube on his face. “There you go. Now fuck me.”
“Kacchan!” Izuku complained loudly, but still complied with his boyfriend’s request, covering Katsuki’s body with his own. He’d deal with the face-lube later; he was far too horny right now.
As Izuku lined up his lubed cock to Katsuki’s entrance, a strong pair of calves wrapped around his waist. He had presumed it was Kacchan’s eagerness to get started. Instead Izuku gasped loudly when the blonde flipped their positions effortlessly, slamming him onto the mattress just as he had done earlier.
“I think it’s time that I show you who’s boss, don’t you think?” Kacchan asked with hungry red eyes, shifting his legs so that he was lined up perfectly with Izuku’s cock. The very sudden change from the shy, submissive Kacchan who had to sweetly ask to be eaten out, to this dominant and demanding Kacchan, was incredibly jarring. Izuku sure as hell wasn’t complaining, though.
He opened his mouth to speak, but instead all that came out was a deep moan when his cock slid in between Katsuki’s ass cheeks. Instinctively, Izuku’s hands trailed around to grab a handful each of his ass cheeks, spreading them apart and kneading the plush muscle, as Katsuki pressed the head of Izuku’s cock against his entrance.
“Keep your eyes on me, you damned nerd.” Kacchan shot Izuku a fierce grin and, before Izuku had time to react, sank down onto his cock in one swift movement. Being sucked into Kacchan’s wet, hot heat was so intense that Izuku could feel it in every blood vessel in his body. If his brain had not started melting at that very moment, he’d have been concerned that Kacchan hurt himself.
“K-Kacchan!” Izuku preened, hoping that his words also conveyed his concern for Kacchan’s pain levels. It didn’t appear that Kacchan was in any pain, though, as after a few moments he bounced greedily on Izuku’s cock, immediately setting a fast rhythm.
“Oh, you’re fucking perfect, Izuku,” Katsuki gasped, running a hand through his own hair to push back the spikes that had gotten stuck to his forehead from sweat. “Now fucking ruin me.”
He tried desperately to buck his hips in rhythm with each of Katsuki’s quick movements, but it was a much more difficult task than anticipated. Katsuki thrusting up into Izuku when he topped looked so easy, but Izuku was having a hard time thrusting upwards with the weight of Katsuki caging in Izuku’s lower half of his body.
“You’re not allowed to cum ‘til I do, got it?” Katsuki demanded through a growl. “If – hng – if you liked my damn fireworks display that badly, you ain’t cumming ‘til you make me do it again. I want you to cum just from the fucking sight of me.”
Izuku nodded and whimpered, not able to do much more as Kacchan rode him.
Katsuki leaned back slightly to put some of his weight on Izuku’s legs, showing off the perfect view of his pecs and waist. His perfect cock slapped obscenely against his abs with every movement, pre-cum smearing up each delicate line of muscle and adding to the thick sheen of sweat already collecting on his skin. His soft, kiss-swollen lips were parted through his gasps, revealing those sharp canines which gave the air of raw, primal strength. He was beautiful, and he belonged to Izuku and Izuku alone.
He knew he’d have no problem cumming just from the sight of Kacchan.
In that moment, he swore he’d never felt such pleasure – the way Kacchan’s ass gripped him tightly, the familiar warmth pooling in his abdomen, the familiar scent of nitroglycerin, suffocating him in all things Kacchan. As if Izuku wasn’t already drowning in him.
As he felt himself getting close to the edge, Katsuki’s warm, damp hand suddenly reached down and closed itself tightly around the base. His grip strength was not anything to scoff at, and he proved it with the strength that staved off Izuku’s impending orgasm. Izuku gave a silent scream at the loss of sensation, while Katsuki continued to push himself up and down, landing on his own hand.
“I know when you’re close, Izuku,” Katsuki hissed, keeping the tight grip around the base of Izuku’s cock. His voice was scratchy with the moans he was trying to suppress. “I told you, no cumming ‘til I do. Was I not fucking clear?” As if to enunciate his point, Katsuki warmed his hand up just enough to send a shiver down Izuku’s spine, chuckling lowly as he saw Izuku gasp. Izuku could hear the cracking from his palm, smell the smoking nitroglycerin, and it was fucking delectable.
“But Kacchan just f-feels so good around my cock,” Izuku cooed, but he was already close enough to the edge when Kacchan sucked him off – he was never going to last like this. Scarred hands gripped Katsuki’s hips to help him ride, possibly digging in so hard he was going to leave bruises. “You look so gorgeous bouncing on my cock like this. Aah – fuck, look at you.”
Izuku’s cock twitched deep inside Kacchan, and he knew that he must’ve felt it, based on the feral grin that took over his features when it happened. Katsuki’s thighs tremored either side of Izuku’s – he must be close, too, if the irregularities of his rhythm was anything to go by. His hands took a tighter grip on Katsuki’s waist, nearly spanning the entire width of them, as the familiar scent of ozone filled the air and their bodies became intertwined with green electricity. Kacchan had noticed it, a tiny confused frown tarnishing the pleasure on his face, but he didn’t have time to react before Izuku thrusted up into him with a small 1% of One For All.
“Fuck, fuck, fuck, fuck, fuck,” was all that could escape Katsuki’s lips – he wasn’t even riding Izuku anymore, just hovering slightly over Izuku’s pelvis as he was aggressively fucked into, almost being entirely unseated with every thrust. “Fuck, Izuku, that’s so good, holy shit, I’m so fucking close, ngh don’t you dare fucking stop–”
One of the hands on Katsuki’s hips was tugged upwards and placed flat against his sweaty chest, holding it there like a lifeline. Exactly where his heart scar was. Izuku could feel the heartbeat under his fingertips as Kacchan tried in earnest to match Izuku’s thrusts desperately. The throbbing heartbeat said what words were unable to do in that moment – I love you with all of my soul, I will never stop loving you until I cease to breathe and even beyond that, you are everything to me. Kacchan’s other hand let go of the base of Izuku’s cock, removing the hand from his waist and pressing it against his own aching cock. Pre-cum smeared all over Izuku’s fingertips as he wrapped his hand around it, but he didn’t even have time to pump it when –
“Fuck, I love you, Izuku, shit–” with lust-blown pupils and a pretty pink flush across his cheeks, Kacchan hit his climax and spurted thick ropes of cum over his stomach and sweat-drenched abs, some of it hitting Izuku’s hand that was on his chest scar too. As his cock continued to pump, throbbing in Izuku’s hand, the fireworks began. Tiny orange and gold microexplosions popped and crackled and sparked all across Kacchan’s body – his cheeks, his clavicle, his pecs, his arms, his hands, his chest, his abs, all the way down to his cock, his ass, his thighs, even his feet. Just as before, Izuku was absolutely enamored at the beauty that was Katsuki Bakugou, riding out his orgasm on Izuku’s cock and moaning so filthily that Izuku wanted to live in this moment forever. His brows were furrowed and face lax, staring intimately into Izuku’s forest green eyes the entire time. The explosions added a painful-pleasure sensation to Izuku’s skin as he fucked up into Katsuki, but the explosions on his cock caged in by Izuku’s hand were too much to bear.
Just as Kacchan wanted, the sheer sight of his orgasm sent Izuku over the edge. He thrusted once, twice, three more times, pushing as deep into Katsuki as his cock could reach, before filling his boyfriend with his cum.
When Izuku’s cock had stopped twitching and started to soften, Katsuki unmounted himself and dropped unceremoniously onto Izuku’s chest, panting heavily. Izuku pushed the damp, blonde hair from his lover’s face, stroking it back. Ever disobedient, the hair fell right back to where it originally lay, but Kacchan practically purred as Izuku continued to play with it.
He lowered his head so his nose brushed Katsuki’s forehead and his lips grazed his ear. “I love you so much, Kacchan,” he whispered, intimate words just for them. “You are so beautiful and radiant. I’m so lucky to have you in my life and to be able to experience this with you.”
Katsuki burrowed his face into Izuku’s neck. “I need you to stop saying cheesy shit after you make me cum.” Despite the bitter words, Izuku couldn’t help but hear how fondly the words were spoken. Pillow talk was never really Katsuki’s forte – Izuku shouldn’t have expected sentimental poetry written in return.
Izuku laughed softly. “I really doubt you mind. Your ego loves it. You would hate it if I stopped.”
“I’m going to make you suffer another week of silent treatment and no sex just for calling me egotistical, you shitnerd.”
Izuku wrapped his arms around Katsuki, holding him tightly to his chest. “No please! I'll take it back!”
They laid in silence, embracing the love and intimacy that radiated between them. Izuku knew they would have to get up eventually, to clean up and to eat dinner, but for now, he enjoyed the pleasant silence. He focused on Kacchan’s breathing, which had slowed down after their workout.
Katsuki broke the silence. “I wonder what the ghosts of Christmas past thought about you misusing your quirk like that.”
Izuku jolted in shock at both the sudden statement, and the statement itself. “Huh?”
“Y’know, the vestiges. Probably rolling in their graves when they saw the ninth wielder using One For All to fuck his boyfriend in the ass like a jackhammer.”
“Kacchan!” Izuku cried, feeling a hot rush throughout his entire body in embarrassment of the vestiges knowing about his sex life. They had proven in the past that they could rummage through his memories at will, and he hoped for a semblance of privacy. He also hoped they could give him privacy when he used quirks during sex. Although speaking of quirks he could use…
“I hope they don’t care, especially since I really want to use blackwhip now.”
“You wanna what?”
