Work Text:
Katsuki was being haunted.
He’d had a great week, all-in-all. Only one overnight patrol shift, which he’d been partnered with Tsuyu for, and she was both borderline nocturnal and relatively quiet, so he didn’t mind her. (Even if she croaked like an actual fucking frog into the otherwise silent street, and startled the shit out of him.) His therapist congratulated him on his fucking stellar self improvement again. Izuku slept over and they got breakfast before his shift. He beat the shit out of some villains with admittedly cool quirks, and some kind soul with a big house threw a party to celebrate everyone’s successful first six months as rookies.
A solid week. Work and play and full points on anger management. Katsuki should be at peace. Katuski would be at peace, honestly, if not for that stupid fucking video.
Mina or Kaminari or Sero or another one of the idiot brigade — someone had sneaked a recording of Izuku at the party, and Katsuki was going insane.
The clip started out shaky, then settled, close enough to its subject that a zoom in wasn’t necessary, the viewer could easily see every twitch of Izuku’s pretty face. Pretty, and flushed, and he wasn’t even drunk, not physically. Just, apparently, intoxicated by Katsuki’s mere presence.
And Katsuki was a fairly private person, and a bit more possessive than he let on, so they didn’t do much PDA. Katsuki didn’t give a shit about public impression, but it wakened something latent and primal in him to think about how he was the only one who got to see Izuku’s microexpressions whenever they touched or kissed or fucked. A million little details, just for Katsuki. So naturally he wasn’t big on sharing them with lowlife extras who would never in all eternity come close to deserving to look upon Izuku like that.
Not that Katsuki really did, either. But he still got to, and damn if he was ever letting him go.
In the video, Izuku and Katsuki were just drunk enough and just comfortable enough around their old friends to flirt in the open. And by flirt, he meant kiss.
And— dear god.
Katsuki himself felt sacrilegious to lay witness on this recording, despite being one of the subjects in it.
Katsuki, known bastard, loved the view of right before he and Izuku kissed, even kept his eyes open, half-lidded, a good half of the time, just to witness Izuku’s intoxicating closed-eyed expression as he leaned in. Flushed and earnest, reaching and wanting. So close, right there to consume.
But Katsuki had never seen that from the side before, and he needed to find the phones of everyone in possession of this video immediately, so he could blow them up and destroy all observable evidence outside of his own. And maybe claw the eyes out of everyone who had ever and anyone who would ever see this.
Because Katsuki was dying, heart giving out, playing the clip over and over and over just to witness the sweet way Izuku begged for him with his entire body. Just for one kiss.
Katsuki was going to eat him.
In the video, Izuku sidled up to Katsuki’s front, head tilted up to meet his eyes; current Katsuki pinked at the hopelessly adoring gaze with which his past-self looked back down at Izuku, hands in his pockets and head bent just slightly, eyes lidded and face straight with a touch of softness around his lips. Involuntary and unavoidable, around his nerd.
Izuku blinked his huge doe eyes up at him, and Katsuki had smirked, said something the audio didn’t pick up — and then it happened.
Izuku’s pretty eyes squeezed shut. Katsuki watched in awe, bent over his phone, as Izuku’s mouth formed a sweet pout, cheeks visibly red and flustered, brow lined with earnestness. And his whole spine reached up to Katsuki, feet threatening to tip toe but not quite getting there, as if Izuku trusted he could get there on his own, or otherwise be met halfway. Shoulders back with the stretch of his neck to tilt his head up, place it higher for Katsuki to hold and own. Back curving just the slightest with the movement, leaning in, in, into Katsuki, pouring want and need from every pore. Trying so hard. And Katsuki-in-the-video watched, teasing just a little by making him wait, dragging his eyes up and down the sight of Izuku asking for a kiss. And then he kissed him. Wholly unaware of the picture they painted from the side, like a ladder meeting a wall, melting into each other where they touched, like soft clay.
Katsuki’s face burned. He played the video again.
Something in his gut curled in heated satisfaction. The clip cut off only a few seconds after they started kissing, and for the life of him Katsuki couldn’t really remember if they kept it relatively decent or devolved to heavy making out, which they were also wont to do. He kind of lost his mind every time he got to kiss Izuku, an experience only heightened when he was drunk and Izuku was drunk and so pretty with it.
Izuku-in-the-video leaned into video Katsuki again. Katsuki-in-real-life held his breath. Then he realized what he was doing and shut his phone off, leaning back in his chair with one hand over his warm face. Jesus. He had it bad.
His heart picked up to the sound of the front door opening, Izuku’s quiet “pardon the intrusion” warming him like a hearth. Katsuki could hear him shuffling as he removed his shoes, left then right like always, and the pause before he remembered to line them up nicely like Katsuki was always getting on his ass about. Katsuki bit back a smile. Shitty nerd.
Katsuki stepped up to the genkan as Izuku was straightening up, and managed to keep a straight face as the other boy froze halfway, looking caught.
“I remembered!” Izuku rushed to say, as if the shoes weren’t neatly placed in front of them both. Guilty conscience, it seemed. Izuku remembered himself and straightened, eyes gooey. “I’m home,” he said.
“Welcome home,” Katsuki recited dutifully, dragging Izuku toward him when he’d barely gotten one foot out the genkan. Izuku oomphed and melted into his arms, cheek round against his chest as he smiled.
“Did Kacchan miss me?” He teased, playing with Katsuki’s shirt hem.
Katsuki scoffed. “It’s been, like, two hours,” he said.
Izuku pouted, because he was a menace. “I missed you,” he grumbled, and then whined as Katsuki pulled at his cheek. “Ow! Kacchan!”
Katsuki pulled Izuku by the wrist to the couch and dragged him into his lap unceremoniously. He let out a quiet sigh. Finally. He wrapped his arms around Izuku’s waist and sank into the cushions. Comfortable again for the first time in hours.
“Did you find it?” Katsuki asked, sliding his hands up the back of Izuku’s hoodie, palms flat on warm skin.
Izuku mhm-ed excitedly, digging into his jacket pocket and holding the item out excitedly.
Katsuki squinted at it. A tiny Dynamight keychain figure from a gacha machine.
He turned his squinting eyes on his boyfriend. “How much did you blow on this.”
Izuku paled a little. “Um... not much… Tokoyami tried a couple times too for Chargebolt…”
Katsuki gripped his waist and growled. “How much.”
Izuku squirmed. “Um. 3000 yen.”
Katsuki groaned. “Izuku...” What the hell else was in that damn machine? Or what were they pricing gacha at these days?!
“I know! But I really wanted it and all the other ones were out and Tokoyami wanted to go with me to Shinjuku for this and you know it’s the only thing missing from my collection, I sold the ones I didn’t want and…” Izuku dissolved into mumbling and Katsuki sighed, keeping one hand on his waist to keep him from jostling too much while he reached into his back pocket for his wallet.
Izuku pinked as Katsuki counted a couple thousand-yen bills and made to hand them over, nearly squawking in protest.
“Kacchan, no! It’s okay!”
“Shut up! I know that was most of your cash, shut up and take it!”
Izuku crossed his arms and shook his head, curiously flushed, so Katsuki rolled his eyes and put it in his Dynamight wallet himself. They wouldn’t get paid for another few weeks. Honestly, this kid.
“Hey!”
“Fuck off. I told you I’d take care of you.”
Katsuki willed down his blush with the force of a thousand All Mights, and looked away as Izuku’s glare turned sparkly and awed.
“Kacchan…” he started, with a hint of tease.
“Shut it.”
Something soft pressed to his jaw, and he looked down to see Izuku staring up through his eyelashes, lips soft like they were in the video. Fuck.
“Did you see—” Katsuki cut off as Izuku pressed a gentle kiss to his throat. He coughed. “I saw this—”
Izuku was making it very hard to focus. “Hmm?”
Katsuki zeroed in on his mouth. He couldn’t remember what he was talking about anymore.
Katsuki took his lips on his next breath, and the other boy hummed into it, pleased. Izuku shifted in his seat, Katsuki’s legs planted wide under his thighs like they always were when he sat, and Katsuki slid down the couch a little to make gravity work for him. Izuku leaned a little heavier on him, and Katsuki grinned against his mouth, sucking on Izuku’s bottom lip to hide it.
They made out lazily, and Katsuki took turns closing his eyes and watching. Feeling nothing but Izuku, his hands and beloved, gentle weight on his lap, his lips and sighs and the wet sucking of their kisses; or seeing nothing but Izuku, a soft pink brushing the tops of his cheeks, Katsuki tilting his jaw into it and watching what it did to him, how his eyelashes fluttered and jaw dropped a little more.
Katsuki dipped his tongue in for a taste, and reveled in Izuku’s shiver. The hands in his hair scratched his scalp pleasantly as Izuku melted into him.
“Does this mean you’ll pay for everything while I buy as much merch as I want?” Izuku murmured against his lips.
Katsuki sputtered and pulled back. “No, you goddamn otaku.”
The brief reprieve from Izuku’s mind-numbing attention cleared his head enough for Katsuki to remember what he’d been meaning to bring up.
“Did you see that video? Us last night?”
Izuku bloomed a furious red. “We took a video last night?”
Katsuki almost blew up the couch. “No, you fucking— at the party. Did Mina show you?”
Izuku shook his head, so Katsuki reached around him for his phone on the coffee table.
He held it facing Izuku, watching his face as it played. Izuku grew steadily more flustered, ultimately peeking through his elbows for the last few seconds. No need to linger on why Katsuki knew exactly how long the video was.
Izuku swallowed. “Well. That’s…”
“Yeah.”
“That’s so embarrassing!” Izuku cried, face in his hands.
Katsuki frowned. Wait, what?
“Wait, what?”
Izuku peered at him, bemoaning. “We were in public… you’re so gay…”
Katsuki slapped him upside the head. “What the fuck.”
Izuku giggled. He was still a light pink. It was a good look on him; Katsuki had to keep him like that as much as possible. At home, of course. Because outside—“
“Everyone could see us like that,” Izuku was still whining.
“I don’t give a fuck about that,” Katsuki scowled.
“But I look so… so…”
Katsuki got up real close to his face. “Everyone already knows you’re in love with me, nerd.”
Izuku honest-to-god squeaked. Katsuki raised his eyebrows. He hadn’t heard a grown man make a noise like that since Koda last tried his Disney Princess act in front of him.
“It’s not that, I look like… like I want…”
Katsuki tried not to smirk too hard.
“Because you did.”
Izuku glared at him, back to oh-so-red. “Well, what’s your problem with it, then.”
Katsuki threaded a hand into curly hair to duck and kiss the soft skin under Izuku’s jaw, relishing in his shivers.
He mumbled his response into the forgiving plane of freckles there.
Izuku scratched lightly at his scalp where he held Katsuki’s head close, and made a questioning noise. “Kacchan, I can’t hear you.”
“No one should see you like that except me,” Katsuki grumbled, louder, peppering the statement with kisses, bookending it with sucking bites. He squeezed Izuku’s waist in a hug.
He felt Izuku swallow and hold him closer. “Oh.”
The hand in his hair pulled his head up, and Katsuki gazed down at doe eyes that never failed to make him feel like explosion was setting off around his heart again. Izuku’s pinked cheeks melted into freckles as he pushed his face into Katsuki’s, taking his mouth with the shy ardent fervor of a long-awaited first kiss. But this wasn’t their first kiss, or probably even their thousandth, so Katsuki dove into his mouth with the pressing smitten hunger of a taken man. He kissed him good and deep, just how Izuku liked it, and Izuku melted into him like he always did, spine bending and stretching to get closer even held together as they were. Their jaws worked and their hands dragged across their bodies, consuming each other, in their own little world in their own little apartment.
Izuku pulled back every so often to press a softer kiss to Katsuki lips, giggle and whisper hi, so overwhelmed he got shy again; it did something terrible to Katsuki, who smothered him in kisses each time to try and contain himself. Katsuki broke off every so often to press softer kisses to Izuku’s lips, too, eyes lidded to watch him. Watch how Izuku angled his head up and closer when Katsuki pulled away even a little bit, chasing him with his eyes closed, mindlessly; how Izuku sighed and blushed and his eyelashes fluttered and his soft lips went from a plush pink to a bitten, swollen wet red. Each of Izuku’s soft sounds was a treasure to him. Katsuki loved this boy.
When Izuku blinked glassy, dazed eyes at him, confused why they stopped, Katsuki had to restrain himself from picking his boyfriend up off the couch and carrying him to their dresser so Katsuki could dig out the ring he hid there last week. Too early for that shit. Katsuki didn’t want to scare him away. But it was a sincere struggle, so Katsuki sufficed to kissing all over his sweet face, holding his cheeks in careful palms, and letting Izuku’s laughter heal every ache in his body.
“I’m disgustingly in love with you,” Katsuki muttered low into his ear, unable to contain it, and Izuku sighed something blissfully happy, cupping his face to fall backwards onto the couch, kissing all over again.
(The next morning, Katsuki sent a very specifically worded message to their class group chat. The video was promptly deleted off every phone.)
(Except Sero’s, who didn’t have the self-preservation instinct, or perhaps healthy fear of Bakugou, depending on who you asked.)
(And Katsuki’s, of course.)
