Work Text:
“Not sure you realise it isn’t very pro-hero of you to normalise breaking and entering into school property, Kacchan.” Izuku points out as soon as he enters his office and sees Katsuki perched on the ledge of his window. Behind him, a vibrant motley of pink, purple and orange melded the thick clouds in the vast sky. It’s beautiful, but not as much as Katsuki, the shape of his silhouette marked by the golden light that shines behind him and would continue to shine from within him even when the sun is long gone. If there comes a day when the stars all die, Izuku already has the brightest one in the palm of his scarred hands.
“Tsk,” Katsuki clicks his tongue at him, “As if you didn’t intentionally leave it open.”
“Oh, so it’s my fault now?” Izuku watches him saunter across the room, their eyes locked like magnets.
When he reaches Izuku’s desk, Katsuki gently grabs his tie, reeling him in just enough for their noses to lightly graze each other. “It’s always your fault, you damn nerd.”
Izuku chuckles, feeling Katsuki cosy up to him as his shoulders drop, his head tilts to the side and his lips part slightly. It’s a wonderful feeling, Katsuki’s body relaxing against his, so malleable in Izuku’s arms. His boyfriend is hardly an unguarded person, but when he’s gazing at him with half-lidded eyes, heart on his sleeve, Izuku can’t help being enticed by the sheer tenderness, uninhibited for no one but him and him alone who gets to indulge in this side of Katsuki.
Which is why it ached for Izuku to have to hold himself back and pull away from his boyfriend before their lips could even touch. He goes to sit in his chair instead, adjusting his glasses while the unaddressed tension in the room draws a bitter pout from Katsuki, who really just looks more adorable than anything. Kind of like a grumpy wet cat.
“Kacchan, I’ve got work to do.”
“And when has that ever stopped you?”
“I think that’s precisely the point.” Izuku raises his eyebrows at him. “I can’t be stopped. If I let you kiss me, it’s going to escalate into something else.” His eyes drop to Katsuki’s lips. “It always does.”
He scoffs, “So?”
“So, these papers aren’t going to grade themselves.”
Katsuki groans.
“Fine.” Izuku watches him cross his arms almost childishly, then mutters something under his breath. “Reject me like you did the night I asked you to join my hero agency.”
Katsuki says it so quick and so faintly, it almost comes across as nothing more than just a petty breeze. Yet Izuku feels the weight of his words smack him like a jarring gust of wind, leaving an uncomfortable chill in his bones. “What?”
Katsuki shrugs, “Nothing, you jerk.”
Izuku glares at him, “Kacchan.”
He frowns, “Kacchan.”
He repeats a little louder this time. “Kacchan.”
“What?” Katsuki finally turns to look at him, annoyed.
The creases on Izuku’s face instantly soften and he just sighs as he rolls his chair over towards Katsuki, nudging him to take off his arm braces and gloves. Then Izuku reaches for both his hands and intertwines their fingers together. He presses a kiss to the side of his elbow through the fabric of his compression shirt, one on his forearm, then his wrist and finally the back of his palm. He looks up to see the sulky expression still scrawled on Katsuki’s face. “Talk to me?”
“I’ve been trying to, Izuku. But you’re always busy and yeah well, so am I… but we haven’t spent as much time together and I–” He watches Katsuki’s cheeks bloom like soft pink roses in the spring, “–I really fucking miss you but you just–”
Izuku reads his mind. “You feel like I haven’t been paying enough attention to you?”
Katsuki nods, slightly hesitant. He still gets occasionally embarrassed talking about his feelings but Izuku thinks it’s sweet that his boyfriend tries to communicate and open up much more since they got together.
“And then well,” he adds, “You said we’d talk about it but we haven’t, and so it’s been bugging me all this time because I’m really trying to be thoughtful, and to respect your decision but fuck, I just can’t understand it and I don’t wanna come off as being too pushy either but then I also feel like there’s something you’re maybe not telling me because it’s just so hard to believe that you don’t want more.” Katsuki rambles in almost a single breath much to Izuku’s surprise. Then he drops to the floor and sits on his heels, sheepishly looking up at him.
Izuku just looks back speechless, furrowing his brows, a visibly apologetic expression on his face.
“Why? Why don’t you want more? Do you not feel like you deserve it or something? Am I not doing enough?”
“What?” Izuku blinks at him, confused. “Kacchan, what are you– that’s not true, of course that’s not–”
“Then why?” Katsuki asks again, his forehead pressed against Izuku’s knee. His hand slips under his pants, wrapping around the back of Izuku’s leg. “Why won’t you join my agency? I really don’t get it. I don’t get you at all.” He squeezes his calf, and Izuku feels Katsuki’s despair in the pads of his fingers making craters on his skin.
“Kacchan, please– this isn’t like you, come on.” Izuku tries to get him to stand up, but Katsuki doesn’t budge.
“Just tell me what I should do.” He bemoans, forehead still pressed to Izuku’s knee. “Tell me what you want, fuck baby I’ll do anything, I’ll make it happen.”
Izuku just stares at him, completely baffled. “You’re not drunk, are you?” He jokes. “I’d have to report you for drinking on the job. And I don’t think Bombshell Hero Great Explosion Murder God Dynamight would be too happy about dropping another eleven spots again.” He nervously laughs.
“Fuck, I don’t care about the ranks, you idiot. I just wanna give you what you want. Why can’t you see what you deserve? Why can’t you see what’s in front of you, huh? All this time I–” Katsuki rambles yet again as he indiscreetly reaches for Izuku’s belt. Even with one hand, he works fast, familiar territory and whatnot, pulling his boyfriend’s cock out from under his boxers.
“Kacchan!” Izuku squeals, startled by the sudden slap of cold air on his flaccid dick, yet he doesn’t stop Katsuki, or at least not really. Any attempt would just be a weak ruse because Izuku knew deep down that he was aching to be touched anyway, especially with work keeping them apart.
So when he feels Katsuki pressing wet open-mouthed kisses to his cock, Izuku just relaxes against his chair and embraces the gesture, not taking his eyes off of him. How can he?
Katsuki was always beautiful on his knees, beautiful with his scrunched brows accentuating the desperation on his face, beautiful with his fiery red eyes glowing with a determination that welled in his throat as he allowed Izuku’s cock to push past his lips. Izuku gratefully moans, loosening his tie while Katsuki takes him nice and slow, and he feels his cock start to harden, filling up the inside of his boyfriend’s mouth.
Izuku bites his bottom lip as Katsuki speeds up, sucking him off with the kind of eagerness and sincerity that would leave Izuku reeling for days. He hollows his cheeks in a pattern that he knows Izuku loves, and swirls his tongue around the tip. The way his lips wrap so perfectly around his cock every time, the way it just slides so deep into the back of his throat with ease, but most of all, the way Katsuki doesn’t break eye contact, looking up at Izuku like he’s craving approbation. Like he’s scrutinising every micro expression to make sure he’s doing it right.
And he is. Izuku feels dizzy. God, he is.
Then he notices it.
The tears pooling in the brim of Katsuki’s eyes.
“Let me see them, baby.” Izuku says as he gently tugs Katsuki’s black mask over his forehead, letting it sit across his hairline, pushing the front of his hair back. As the tears stream down his face, his mascara inevitably smears. And yet, even ruined, is when Katsuki looks most ravishing.
“Hey,” Izuku exhales, “Take it slow.”
But Katsuki just shakes his head, mouth still stuffed with cock, in fact swallowing it even deeper until his nose is practically buried in Izuku’s pubes.
“Kacchan, hahh–” Izuku gasps, feeling Katsuki’s stifled moans vibrating on his cock. As his throat closes around the head each time he sinks down on him, Izuku feels the knot in his stomach tighten.
His tears would continue to flow, and Izuku wanted to just pull him up into a hug. Yet watching Katsuki cry in subservience and an utter devotion to please him, Izuku can’t help feeling even more aroused.
“All this time…” Katsuki whimpers, a single string of saliva connecting his bottom lip to the precum that glistens on the slit of Izuku’s cock, “Been waiting for you… Need you…”
Izuku reaches for Katsuki’s cheek, thumb brushing tenderly over the tear stains on his face. And he knows. Izuku knows it’s not just the sex he’s talking about. But also the offer to join his agency that Izuku had so woefully rejected back then. Somehow maybe the negative feelings Katsuki had repressed since that night got all mixed up with his sexual frustration and now he's just completely dazed, like he won’t even be able to tell the difference in the relief between his offer being accepted and his body basking in orgasmic bliss.
Perhaps, because Izuku is central to both.
Like he is to most things in Katsuki’s life.
“Please–s’Zuku, hnnfgh…” He whines, clutching Izuku’s leg harder as he starts to rut against it.
“Fuck, Kacc–Kacchan!” Izuku feels the heat rise to his cheeks. He knows just how shameless Katsuki can get during sex yet it still surprises him every time. The way that he exerts control by being so pathetic it just renders Izuku dumbstruck under his advances. And he likes it. God, he likes it so much.
“Kacchan, if you keep going, I’m gonna come…” Izuku moans, his hand surging forward to grab Katsuki’s hair. Katsuki just responds by humming as he continues to bob his head at a vigorously satiating pace. The buzzy sensation that it sends around Izuku’s cock makes his nails dig into his chair as he violently jerks and his shoe involuntarily tilts up, pressing into Katsuki’s perineum.
Izuku feels him jolt, squeezing his ankle so that his foot stays there, perfectly angled between Katsuki’s thighs, like some optimal contraption. The faster he grinded, the harder he sucked, the more Izuku convulsed, the greater the pressure of his foot against Katsuki’s cock.
“Hnnfgh, need more… fuck, s’not enough Izuku, please–” Katsuki whines again, humping his foot so desperately it’s driving Izuku to the brink.
Between Katsuki’s tears cascading down flushed cheeks, smudging his mascara even more, slobbering all over Izuku’s cock, begging to come, it was just too much.
“Kacchan, shit– I’m gonna come, I’m really gonna– hnnfgh… FUCK!!” Izuku shouts when he feels the vehement snap in his body, arching up as his orgasm tears through him in rapturous waves and he explodes right into Katsuki’s mouth.
Izuku haphazardly rips open half the buttons on his shirt, chest heaving as he tries to catch his breath. Though he only gives himself just a few seconds of grace before leaning forward to pull Katsuki into a kiss. Unsurprisingly, he’s swallowed all of it yet Izuku could still taste himself in the recesses of Katsuki’s mouth.
As they kiss each other, soft and firm lips moving with an urgency so intense, it’s almost euphoric, Izuku slowly pulls him up with one arm while the other shoves everything off his desk in a frenzy.
“Wanna come– shit, Izuku please…” Katsuki pleads into his mouth, nuzzling his nose against Izuku’s, “Make me come.”
“I know baby, I know.” He coos, heart thumping seeing Katsuki look at him with teary eyes, pupils blown out with lust that reflected his own. “How do you want it?”
“From the back.”
Izuku nods as he kisses him again. “How many?”
“Four.”
“Can you take it?”
“Fuck, don’t ask stupid questions–s’Zuku, come on.” Katsuki whines and Izuku cackles against his lips.
“I’ll make you feel so good, Kacchan. I promise.” He says, gently pushing Katsuki face down so he’s bent over the desk. Izuku carefully detaches the neck brace of his costume and tugs down the high collar, pressing a kiss to the tiny star on his nape with Izuku next to it. Katsuki recoils, ticklish. But Izuku knows just the trick to distract him so he hastily undoes Katsuki’s belt and slips his hand inside. Subdued under his touch, Katsuki relaxes against the palm caressing his dick through the fabric of his underwear.
Izuku goes on to thumb the spot where his name had been inked, remembering the first time Katsuki showed him the design of the tattoo that he had planned to get.
Kacchan, you know this is permanent right? Izuku had asked, worried.
No shit it better be, Katsuki would just reply like it was the easiest decision he has ever had to make. To fall so deeply in love with someone, you want them anchored beneath your skin forever.
Izuku presses another kiss to the tattoo, a constellation of his birth sign snaking down the back of Katsuki’s neck and disappearing into his shirt. There was a cute, tiny crab in the middle of it, that Katsuki had asked Izuku to doodle specifically for him to get tatted.
But Kacchan, I’m no artist! Are you sure it’s not going to ruin the tattoo?
Damn it, Izuku! I just need a tiny doodle. How hard can it be to draw a stupid crab?!
Izuku chuckles fondly at the memory. He lifts Katsuki’s shirt up to his shoulders, exposing the rest of the tattoo. An orbiting star sits beneath the crab at the point where his constellation diverges, and on the left of that, is another constellation — Katsuki’s. A bunch of stars that look like the explosive sparks of his Cluster move and some cosmic swirls meant to depict him chasing Izuku for the rest of his life, just like he promised.
Izuku presses his lips to the skin there, where the tattoo spans across his left shoulder blade, embedded with the scar from when Katsuki had jumped in to save him from Shigaraki’s rivet stab spikes. As Izuku litters him with kisses, he feels the bone stirs under Katsuki’s skin like a creature about to break the surface tension of the sea. At the very tip where Katsuki’s constellation meets the orbiting star, is the name Izuku has called him all his life. A once spurned sobriquet now a term of endearment seared into his skin and his soul all the same.
“Mhmm, my Kacchan,” Izuku whispers, kissing him there too.
Hand still wrapped around Katsuki’s cock, Izuku slowly moves lower, hovering around the muscular creases, admiring the way they dip and fold under his warm breath and heated kisses. He licks the sweat where his skin curves at the spine and Katsuki squirms beneath him, his ass rubbing into Izuku.
“Shit, enough with the teasing…” He murmurs, but it’s not like Izuku can help it when his boyfriend is so damn broad.
Katsuki was, always bigger than Izuku. That’s a known fact. Always the more stronger-looking. Always whom people probably secretly assumed is the one who tops when he would tell them that they were dating.
Yet only Izuku knows how Katsuki really likes it. How pliant he can be under his touch. How easily he bends to his will when it’s just the two of them. And where the light meets its reflection, not even the boldest and brightest star in the galaxy is immune to the volatile ocean bringing it down to its knees in soft, sun-kissed waters.
“Izuku I’m so serious, if you don’t get the fuck in there right now…” Katsuki grumbles, and Izuku laughs against the small of his back, kissing his dimples there.
His free hand grabs Katsuki’s waist and the way it almost feels strangely small compared to the rest of him, Izuku doesn’t even know how he had managed to acquire such a body shape. But he’s sure as hell going to tell Katsuki to keep doing whatever the heck it is that he’s been doing because good god, if it doesn’t make him look incredibly sexy when he’s ass out under Izuku.
“I’m sorry, baby. You’re so beautiful, I just have to savour this moment.”
“Make me come and I’ll give you something to savour huh, how about that?”
Izuku laughs again, “You know, I liked it better when you were begging and crying.”
“Wha–?! Sh–shut up!!!” Katsuki snaps, his ears turning awfully red like he didn’t just go crazy on his boyfriend earlier.
Izuku cackles as he slips his fingers under the elastic band of Katsuki’s underwear, and pulls both that and his pants down in one fell swoop. Izuku eagerly gets on his knees, giving Katsuki’s ass a firm squeeze before spreading him open. His mouth hovers over the puckered hole, and his warm breath alone was sufficient to make Katsuki tweak. Izuku watches him grip the edge of the desk as his tongue darts out to lick the rim before pushing it through the ring of muscle. He feels Katsuki’s legs go momentarily weak at the gesture, so he slides his hands down to his thighs, his outrageously big thighs, a monstrosity that Izuku has had the pleasure of having his head wrapped around, and holds him there to keep him steady.
Izuku continues to prod and lick with his tongue, ferociously almost, drawing out a string of needy moans from Katsuki who can barely keep his legs straight. Izuku reaches for the bottle of lube he keeps in his last drawer, slicking two of his fingers with the liquid and rubbing around Katsuki’s entrance. Izuku presses a kiss or two to his ass, biting on the supple flesh gently with his teeth. Then he slowly pushes his fingers in, feeling the tightness envelope him.
“Haah, mhmm–mo–more… Fuck Izuku, more…” Katsuki already wails, impatient as ever.
While Izuku typically enjoys taking his time to take Katsuki apart piece by piece, he wanted to adhere to his boyfriend’s wishes so he quickly reapplies the lube and pushes all four fingers inside instead, ripping a guttural moan out of Katsuki who grips the desk like he’s going to break it. And he probably could, from being split open so deliciously on his fingers. Izuku thinks he might get hard again from just watching Katsuki like this.
“Kacchan baby, you okay?”
He nods, panting, “Ye–es, yes haah… Izuku move.”
So he does, working his fingers against the tight ring of muscle practically swallowing him in, his fingers curling down deeper until he can feel the soft fleshy nub inside. Izuku spits on Katsuki’s balls and flattens his tongue against them, licking and swirling it in a way that he knows will make Katsuki’s whole body convulse, which it does.
“Shit fuck–” He moans, as Izuku fully engulfs his balls into his mouth, gently pulling at the skin and squeezing around them. Over in the front, his hand eagerly strokes Katsuki, just narrowly missing the tip. “Haahhnnfgh god…”
Oh you beautiful, sensitive little thing, Izuku thinks to himself as he keeps going, taking pride in watching Katsuki fall apart before him, again and again and again, like a cycle of nature. As he strokes him, he gently pulls back Katsuki’s dick, long and splendidly curved, tucking it between his thighs. A bunch of earnest kisses here and kitten licks there then it’s shrouded in Izuku’s mouth, fingers still knuckles-deep fucking into Katsuki relentlessly while the bottom of his palm presses pleasurably hard against his balls, all at once. A copious sensation so overwhelming, Katsuki can only afford to tremble helplessly and erratically like the strings on a violin as Izuku plays him over and over and over, drawing out his moans like his favourite music piece. And it is surreal.
“HNNFGH FUCK–” Katsuki yells, gripping the desk so hard he might just actually make the wood snap. He could hardly move otherwise, with Izuku clasping his legs together with his knees to keep his dick lodged, rubbing between his own thighs. “Oh god, oh my god,” he pants, twisting one arm back, and grabs Izuku’s wrist. “What the fuck was that–”
Izuku just gasps as he watches Katsuki lift his head up from the desk, turning around to meet his eyes. He notices a fresh streak of tear stains glisten in the light over the ruined mascara and god, Izuku’s cock was throbbing in his pants. “Did you like it?”
“Shit, are you kidding?”
Izuku cackles.
“Just don’t– fuck, don’t slow down...” Katsuki mewls, arching his back as he tightens his grip around Izuku’s wrist, getting his hand into motion again.
“Tell me,” Izuku says, “Tell me when you’re gonna come, Kacchan. I wanna look at you.”
He watches Katsuki quiver, knowing the coil in his stomach must be impossibly tight by now as Izuku’s fingers speed up kneading into his prostate. Izuku feels his cock twitch in his mouth as Katsuki continues to fuck his own thighs with it, and he knows Katsuki is close, so he keeps going, keeps hitting the sensitive spots that make his whole body spasm. At this point, Katsuki can barely stand, his legs visibly about to give out.
“Izuku, Izuku, Izuku please, haahhnnfgh–” He whimpers, drooling. And it didn’t have to be the exact words for Izuku to know that Katsuki was reaching his peak. All he knew was that every time he was going to come, Katsuki would chant Izuku’s name like a mantra. A name he couldn’t bring himself to say for years, now the one he calls out to for solace. A word that was once heavy on his lips, now rolls like honey off his tongue. And it just makes Izuku’s heart flutter.
And perhaps also, his dick uncontrollably hard.
So Izuku quickly pulls it out again as he gets on his feet and flips Katsuki over on his back. Wrapping his hand around their cocks, he starts to stroke both of them together.
“Holy fuck, haah Izuku…” Katsuki purrs, and Izuku watches the expression on his face as his hand vigorously slides over and over.
He wanted to see the way Katsuki’s brows contort in pleasure, glassy eyes rolling up to the back of his head, barely able to keep them open. The way he tilts his head back into the desk, mouth gaping as the moans spill out of his throat. Izuku wanted to bear witness to everything.
Then he reaches for Katsuki’s shirt, lifting it up past his chest and sees his flushed body shake uncontrollably as Izuku swirls and squeezes around the heads of their cocks. The sporadic movement makes them violently twitch, until they’re both coming all over Katsuki’s pecs and stomach.
Izuku takes a moment to just look at him, utterly endeared, like admiring a breathtaking work of art. He leans down to lick the viscid white liquid, leaving a bunch of tender kisses as he moves up to Katsuki’s neck, the side of his jaw, the scar under his eye, his nose, and finally his lips, giving Katsuki a taste of himself.
Then Izuku rests his head on Katsuki’s chest, their bodies melting into each other as he quietly listens, letting the sonorous beat of his heart carry Izuku through the riveting otherworldly state that intertwined his soul and Katsuki’s, tethering them to a high he never wishes to come down from.
Izuku jokingly knocks on his chest. “You okay in there?”
Katsuki scoffs, panting still, “Hey, just because my heart can’t go back to the way it was doesn’t make it any less durable.”
“I know, Kacchan. But sex is cardio, so you could, theoretically, get a heart attack when it gets too much.”
“Too much, huh? Perhaps you should’ve thought about that before whatever crazy shit you were doing.”
Izuku chuckles. He slowly gets up and sits next to him on the desk, hauling Katsuki over to his side so that his head laid in his lap. Despite still looking slightly disoriented, Izuku could see that Katsuki’s features were more relaxed, and that his breathing had slowed down to a steadier pace. Izuku combs his fingers through his disheveled blonde hair, much softer than it looks, as his other hand slips over Katsuki’s waist and entangles their fingers together.
Izuku adored intimate moments like these. Adored having Katsuki in his most raw and honest form. The way he can feel Katsuki ease up into him completely, familiar by the shape of his soul, the warmth radiating off of it and his body all the same. The soft, yielding essence that binds him at the very core of himself, existing behind all that pugnacity and toughness, like marrow in the bone. Izuku continues to brush his hair, basking in the gentle stillness of Katsuki unwinding in his embrace, expressing vulnerability time and again that Izuku just can’t believe he could be deserving of holding such sacredness in his calloused hands.
“I guess,” Katsuki suddenly says, his voice mellow, and the soft lull of his breathing interrupted, “I just really wanted us to keep chasing after each other forever, that’s all.”
“Chase each other?” Izuku sweetly caresses his cheek. “Kacchan, we already have each other.”
“You know that’s not what I mean.” He whispers, voice cracking like it’s stuck in his own throat. “Why can’t you just be selfish for once, huh? Why are you so overcome with this need to make everyone else but yourself happy?”
The words strike Izuku like an unsuspecting wave hitting a cliff, slowly but surely eroding his self-containing facade.
“I am happy, Kacchan.” He says, a pounding ache in his heart.
Katsuki turns to look up at him, not fully convinced. “Are you really?”
“Well, I’ve got the best boyfriend in the whole world, and I’ve got amazing friends, and people who still look out for me, and I love my kids here at UA. And I still get to do hero stuff occasionally thanks to you.”
“And that’s enough?”
Three words. Three simple words, yet such lethal intent masked behind an innocent question and unfaltering eyes that looked so dearly to him, stunned Izuku into silence.
He frantically blinks and looks away, though still holding onto Katsuki’s hand where Izuku feels the tender but firm brush of his thumb as if quietly encouraging him to speak.
Izuku sighs, “I figured out what you mean, you know? That night, in the car, when you told me that if I treated everyone as special, then no one really is.” He pauses. “You were talking about yourself. Weren’t you?”
It was Katsuki’s turn to look away, flustered.
“Kacchan, you’re the most special there is to me.” Izuku reassures him. “Enrolling in UA, having One For All, going into the battles that we did, they all felt special because I had you. And I only wanted others to feel special too so I could inspire them the way that you inspire me. To make them believe they can do anything when they look up to me, the way I’ve always looked up to you.”
“But it doesn’t have to stop at teaching, does it?” Katsuki asks. “It’s just, you can’t expect me to believe you’re satisfied with everything right now when I know more than anyone how much your dream means to you. I was there the whole time, wasn’t I? I mean yeah, I was an honest to god dickbag but you,” he awkwardly pauses, “you know what I’m trying to say. I just think at some point, it felt like your dream became mine too. Your pain, your struggles, all of it. Everything that you’ve shown me and everything that you’re still hiding, I want to know,” Katsuki gently taps Izuku’s forehead, “I want to know everything in here,” he taps his chest where his heart is, “and in here.” He cradles his face and Izuku leans into his hand, like it was always made to hold him, “baby, you hear me? Whatever you feel like you couldn’t say before, tell me all of it.”
“Okay,” Izuku nods, the corners of his lips curling up into a smile, “No more secrets.”
He feels a slight relief wash over him and truly, Izuku couldn’t be more grateful to Katsuki for his constant solicitude, for the comfort in his words and the sincerity in his actions. Just the sheer devotion to surrender himself to Izuku as if he lived for him, as if he couldn’t be anything without him, even when he already was one of Japan’s strongest and most revered.
Because Izuku knew without him, none of that genuinely mattered to Katsuki anyway. For so long, Izuku had settled with accepting that having One For All on borrowed time gave him a sufficient glimpse at the dream his heart has always longed for. Clearly, that never sat right with Katsuki, with all his tenacious whims, unstinting loyalty and whatnot.
And Izuku thinks how wonderful it is to be part of a love so defining, it transforms a person into the best version of themselves.
He cups Katsuki’s cheek, gazing at him, long and fond. Then Izuku leans down to kiss him, whispering into his mouth, “I love you,” as if he could possess him by doing it.
“I love you more.”
Izuku snorts. “It’s not a competition, Kacchan.”
“What are you talking about? It’s always a competition with you.” Katsuki says as he sits up. “Besides,” he kisses him back harder, tugging on his bottom lip slightly, “I could do a second round.”
Izuku cocks an eyebrow at him. “No way, this desk has seen enough tonight. Aizawa sensei will literally kill me if I break it again.”
“Well shit, I’ll pay for it.”
“And confirm his suspicions that we’ve been fucking in my office?”
“Izuku, he already knows we’re together.” Katsuki shrugs. “Everybody does.”
“Yeah, maybe because you’re always squatting by the window waiting to be let in like a domesticated bird.” Izuku deadpans.
“So are you complaining?”
He clears his throat. “No.”
“Good.” Katsuki smiles, pushing Izuku down on his back as he climbs over him. “Then shut up and fuck me.”
