Shouto slowly opens his eyes, the soft glow of sunlight spilling through the half-drawn curtains making everything look ethereal and warm in the early morning. He yawns, instinctively stretching his limbs, only to be stopped by two heavyweights on either side of him. He turns his head to the left and sees Izuku, the sight of him causing his heart to skip and beat faster. His tangled green curls are a mess against white sheets, his cheek squished against the pillow, his lashes projecting a delicate shadow against his cheekbones, the sprinkling of freckles dusting his cheeks reminding Shouto of a constellation, dots of starlight scattered across his skin, trailing down to his bare shoulders. The overwhelming urge to reach out and trace those freckles with his fingers—to experience their softness once more—hits Shouto like a wave, rendering him breathless.
“He’s too pretty for his own good,” comes a gruff voice from his right, startling Shouto from his reverie. He sees Katsuki sprawled beside him, a striking contrast of pale blond and scarlet red. Shouto’d never seen him like this: half-lidded eyes glazed over with the remnants of sleep, blond spikes undone by eager hands, soft pink lips slightly swollen, evidence of what they shared just hours before. Shouto kissed those lips last night—he couldn’t help but recall how warm they were, how electrifying the connection felt, shivers coursing from his core to the tips of his fingers. He wants to kiss them again.
“You’re one to talk,” Shouto responds, voice raspy from sleep, delighted to see the flush that spreads through Katsuki’s cheeks.
“Shut the fuck up, Halfie, it’s too early for this,” Katsuki grumbles, though the hint of a smile dances at the edges of his lips.
“-oo early fo’ wha'?” Izuku mumbles, eyes barely open, his words thick with sleep.
Shouto shushes him gently, fingers weaving through Izuku’s messy curls, smoothing them down. “Nothing, baby, go back to sleep,” he whispers.
Izuku lets out a soft sigh of contentment, closing his eyes. “Mmkay.”
It takes mere moments before his breathing evens out, deep and peaceful once more.
“He’s baby now, is he?” Katsuki whispers, smug, and Shouto glares at him, fighting to control the flush creeping up his cheeks and spreading down his neck. If the smirk on Katsuki’s face is any indication, Shouto’s efforts are useless.
“Be quiet, Izuku’s sleeping,” Shouto whispers back, carefully dislodging his hand from Izuku’s hair and turning his body in Katsuki’s direction.
“I wouldn’t dare disturb baby’s sleep,” Katsuki taunts, the smirk never leaving his face, and without thinking, Shouto leans in—ecstatic that he’s allowed to do that now—and captures Katsuki’s lips with his own, if only to shut him up. Katsuki kisses him back with a fervour that leaves Shouto breathless, his rough hands finding purchase at Shouto’s waist and around his neck, pulling him closer, and he melts into the warmth, utterly addicted.
With renewed vigour, Shouto pushes Katsuki’s shoulders into the bed, getting on top of him and spreading his thighs to fit Katsuki between them. Katsuki grumbles, annoyance barely contained, but Shouto quiets him again, kissing his mouth and distracting him from their changed position. Shouto kisses his lips, the corner of his mouth, his cheeks, his scar, his jaw, all the way to his right ear, and then he licks. Katsuki groans, shuddering, and Shouto shushes him, whispering against his ear, “You have to be quiet, Katsuki. Izuku’s sleeping.”
Katsuki shivers, full-bodied, and the hand around his waist tightens. “You’re making it very hard to be quiet, princess,” he whispers back, gripping Shouto by his split hair and bringing their mouths together again, tongue twirling around tongue. Shouto melts against him, addicted to the pressure, reciprocating the action enthusiastically. He sucks on Katsuki’s lower lip and fits one of his legs between Katsuki’s thighs, grinding down. Katsuki moans loudly and startles with the intensity of the noise, disrupting the kiss and looking hastily to the side, where Izuku lies asleep. Shouto chuckles, delighted by the urgency, and Katsuki glares daggers at him. “You son of a bitch, you’re doing this on purpose.”
Shouto smirks, feigning innocence. “I have no idea what you’re talking about.”
Katsuki’s eyes darken, mischief dancing around scarlet red. “I’ll show you.”
Abruptly, Shouto is pressed against the bed, roles reversed.
Katsuki goes straight for his neck, and Shouto has to inhale deeply to avoid moaning, an all-encompassing shiver taking over his body.
He confided to them yesterday, confessing that he’s only ever been with a scarce few people and the sole discovery worth his time was learning about his sensitive neck. Izuku sheepishly asked if he could kiss it, and Shouto had no intention of denying him, nodding right away. What resulted from that was a memory Shouto would never forget—a warm tongue and gentle teeth sweeping through his skin, creating heavenly trails all along his throat. He shivers from the thought, remembering green curls and starlight freckles, huge emerald eyes looking up at him like he was the sun.
Katsuki startles Shouto from his reverie again, biting hard into the junction between his ear and neck. Shouto moans, incapable of containing the noise, and his whole body jolts upwards, chests and hips colliding together. He feels Katsuki’s smile against his neck before he licks a path to his Adam’s apple. Shouto closes his eyes and fights to suppress a whine, weaving his fingers through blond hair and pulling hard, making Katsuki groan, but Katsuki endures the pull and clings against his neck, leaving hickeys far and wide.
A third hand reaches for his hair, turning his gaze directly to sleepy emerald green, and Shouto’s breath catches in his throat, unable to look away from the pout adorning Izuku’s lips. “Not fair, Kacchan. Why didn’t you wake me up?”
Katsuki bites Shouto again, and this time Shouto doesn’t contain the whine that comes tumbling out of him. Katsuki leaves one last hickey before withdrawing from his neck and looking at Izuku. “Shouto didn’t want to wake you,” he says, and although it’s true, Shouto can’t help but feel betrayed, glaring at Katsuki, squinting his eyes, but Katsuki only smirks.
“Shouto!” Izuku whines, pulling on his hair again. “Why didn’t you?” he asks, pouting back full force. Shouto sighs, pushing Izuku’s lower lip back into his mouth and caressing his cheekbones, creating his own constellation. The red flush on his cheeks is one of the prettiest shades of red he’s ever seen, second only to Katsuki’s scarlet eyes.
“‘Zuku, you looked so peaceful… I didn’t want to disturb you,” he whispers, and the shy smile on Izuku’s face makes everything worth it.
“Bullshit, he only wanted to make my life harder,” Katsuki retorts and Izuku giggles when Shouto turns to glare at Katsuki.
“No, I believe him, Kacchan,” Izuku says, wrapping both his arms around Shouto’s waist and clinging to him. Shouto feels so smug he can’t help but smirk at Katsuki, who only scoffs and goes back to ravaging his neck. Shouto closes his eyes and inhales, grinding up just so he can feel the vibrations of Katsuki’s moan against his throat.
The soft touches brushing his waist pull him back to the present, and when Shouto looks at Izuku, Izuku’s already staring at him, huge emerald eyes looking up at him like he’s the sun, and Shouto burns. Is that how Katsuki feels every morning?
“Good morning, Shouto,” Izuku says, oh so softly, and Shouto has no choice but to tangle his fingers into green curls and pull him closer, pecking his lips.
“Good morning, baby,” he whispers back, in awe with the flush that engulfs Izuku’s whole face. Izuku starts spluttering, but Shouto takes him by the hair and kisses him, promptly interrupting him. He feels Izuku melting in his hand, sighing against his lips, kissing him back in no time at all.
Shouto thought about kissing them for the longest time—probably years if he had to guess. He hadn’t realized that’s what he was doing, at first, but every time he went on a failed date and the person asked Shouto to kiss them, Shouto couldn’t help but think of emerald green and pale blond, of starlight freckles and rough scars, until it finally clicked, a few months ago. Shouto was in love with them—irrevocably so.
It all came to a head last night when he finally told them. Izuku cried—but when didn’t he?—and Katsuki smiled, sharp edges softened up for the briefest moment, and he felt like the luckiest man in the world.
The memory makes him feel ablaze.
Shouto licks into Izuku’s mouth and feels his moan against his lips, scarred hands tightening their grip on Shouto’s waist as Izuku gets closer, grinding his hips against Shouto’s thigh.
Katsuki dislodges himself from Shouto’s neck and reaches for Izuku’s ear. “You’re enjoying this, aren’t you, baby? Do you get off on how hot his tongue is? How excruciatingly cold it feels against your teeth?” he purrs. Izuku withdraws from the kiss and moans loudly, grinding harder against Shouto.
“Kacchan, don’t be mean,” he whines, but he continues to grind down, proving Katsuki’s point. Shouto reaches for Izuku’s neck and licks, making him shiver, and Katsuki seizes his chance to kiss Izuku, taking his right hand off of Shouto and grabbing green curls, pressing his head against the bed and kissing him hard. Shouto can feel the vibration of Izuku’s moans through his throat—can feel the desperation of the hands gripping his waist—urging him to touch. Shouto releases his grip from Izuku’s hair and traces his freckles with the tips of his cold fingers, trailing down to his bare shoulders and causing a full-body shudder. He travels through a sturdy chest and hardened nipples, flicking them with the pad of his thumb. Izuku throws his head back, moaning, rutting his hips against Shouto, and Katsuki snickers.
“What you doing down there, princess?”
Shouto ignores him, tracking down his fingers until he reaches between Izuku’s legs. Izuku’s whole body jolts upwards, a surprised shout trailing off into a moan. He ruts against his hand, whining, and Katsuki tsks, no doubt annoyed with Shouto’s lack of response. Katsuki’s left hand grips Shouto’s hair, forcing him to look up at scarlet red.
“You ignoring me?”
“How observant of you,” he responds, voice monotone.
“Smartass,” Katsuki says, bringing his face close to Shouto’s, biting his cheek in annoyance, but Shouto retaliates by licking his ear, eager to feel Katsuki shudder again. Katsuki yelps, and Shouto’s not disappointed—goosebumps appear throughout his body, pale blond hair erecting everywhere. Katsuki recedes, indignation rolling out of him like a wave, and Shouto can’t help but smirk.
“Kacchan,” Izuku whines, drawing one of his hands away from Shouto’s waist and reaching for Katsuki’s neck, pulling him closer. “Why did you stop kissing me?”
Katsuki snorts. “Sorry baby, it was kind of hard to keep kissing you when you couldn’t stop moaning,” he says, and Izuku flushes the prettiest pink. Shouto takes the opportunity to speed up his hand and force Izuku to moan again, making Katsuki laugh. Izuku glares at him, betrayed, and Shouto kisses his pout in a silent apology, following his first peck with several small kisses all around his face, making Izuku giggle.
Shouto draws back and smiles at him, his heart close to bursting. He repositions his weight into his left elbow and uses his left hand to hold Izuku’s jaw, tracing his freckles with his thumb while he fastens the pace of his right hand again, studying Izuku’s face as his eyes close and his mouth opens in a silent moan, pink lips puffy and moist from kissing, lashes wet with the onslaught of pleasure.
It’s incredible how Izuku’s beauty takes his breath away every single time.
Katsuki follows his lead and kisses Izuku’s neck, using his hands to grip green curls and flick his hardened nipples. Izuku thrashes against the bed, thrusting into Shouto’s hand and moaning so deeply Shouto wonders if they’ll get any noise complaints when the afternoon comes, but not bothered enough to stop—the apartment isn’t his, anyway, let them deal with the consequences.
“A-Ah! Kacchan! Shouto!” Izuku cries, moving his arms and hugging Shouto’s head against his chest, holding on for dear life.
Katsuki trails a path of kisses through Izuku’s neck, reaching his ear and purring, “You wanna come, baby? Wanna paint Shouto’s chest with your cum?”
Izuku cries out again, closed eyes filling with tears, and it takes three more thrusts before he moans and quivers, trapping Shouto into his sturdy chest while his cum gathers in Shouto’s hand and paints his belly in hot stripes. They freeze in time, relinquishing the pleasure, until Izuku becomes boneless, letting go of Shouto’s head so he can lay down again, breathing erratically and sweating profusely. His cheeks are flushed, concealing most of his freckles, and his green eyes gleam with unshed tears.
“That’s so unfair,” he breathes softly, looking between Katsuki and Shouto, making grabby hands at them. Katsuki chuckles, repositioning in the bed so he can lie to Izuku’s left and cuddle with him. Shouto stays where he is, unsure what to do next.
“You’re the only one that came and that’s unfair?” Katsuki asks.
“Yeah! You ganged up on me…” Izuku says, pouting. “We should have ganged up on Shouto…”
“Hey,” Shouto protests, but it’s too late.
Katsuki stares at him, mischief in his eyes. “That’s a great idea, baby,” he agrees with Izuku, making him giggle. Izuku gets up on unsteady legs and rolls over Shouto, essentially returning Shouto to the middle. He starts protesting again, but scarred hands reach for his face and pull him into a kiss, interrupting him. He sighs into the kiss, addicted to the softness of Izuku’s lips, until a second pair of hands touch his thighs and spread them, startling Shouto out of the kiss.
He looks down and sees Katsuki smirking at him, suddenly not at his side anymore. Rough hands reach between his legs and direct his cock to Katsuki’s mouth, heavenly warmth enveloping his length, and Shouto can’t help but throw his head back and moan, gripping blond hair and thrusting up. Katsuki, to his surprise, does not choke, but takes him deeper, squeezing his throat around him. Shouto cries out and closes his eyes, trying not to embarrass himself by coming early, when Izuku giggles at his side and kisses his neck, whispering in his ear, “Kacchan is so good with his mouth, isn’t he?”
Shouto holds his breath, concentrating all his might into not coming instantly, the edge so close fire spreads from his belly all the way down to the tip of his toes, and pulls on Katsuki’s hair until he grunts and lets go of him, only managing to lick his tip. Shouto breathes out, relieved, opening his eyes again and glaring at mischievous scarlet eyes.
“What, you scared of coming, princess?” Katsuki asks, smug. Shouto squints his eyes at him, still holding his head away from his length or risking being overcome by overwhelming heat once again.
“I’ve never done this, Katsuki, be good,” he demands, and Katsuki’s eyes darken and glaze over, looking at him with unthinkable hunger. By his side, Izuku whimpers, kissing his neck softly and reposing his head against Shouto’s shoulder, hugging his waist and observing Katsuki.
“…Never?” Izuku whispers, voice gentle against the sensitive skin of his neck.
Shouto shakes his head, suddenly shy. “I’ve… done it to other people, but never let others do it to me,” he says, voice low, only audible due to the expectant silence around them. Katsuki closes his eyes, breathing deeply, and when he opens them, he nods, determination written all over his face, red eyes set like he's ready for a new challenge. Shouto feels himself blush, so attracted to him he doesn’t know how to sort out all of these complicated feelings inside of him. Luckily, he doesn’t need to—he has all the time in the world, now that he has them.
Slowly, Shouto lets go of pale blond hair. Katsuki stays put, only kissing gently at his tip before licking through the whole length, making Shouto moan again, twitching against his tongue. Katsuki smirks at him but takes everything at a leisurely pace this time. He makes out with his cock, tongue dancing around his length, spit going down his balls and almost dripping to his ass, until Katsuki licks it all up and envelops him in warmth again, going down inch by inch unhurriedly. The pace is agonizing, and yet it’s the best thing Shouto’s ever felt.
The edge builds up a lot gentler the second time, sparks running through his veins, his belly turning into a full-fledged fire, his blood spreading liquid blaze to the tips of his fingers. He closes his eyes as he starts to come, thrusting into Katsuki’s throat one last time before freezing and moaning, shooting hot cum into his mouth. The pleasure he feels is all-encompassing, making him quiver and cry out until the texture of Katsuki’s tongue becomes too much against him, overwhelming. He reaches for pale blond and whines until Katsuki lets go, scarlet eyes half-lidded, puffy lips smeared with his cum. Shouto reaches for him, kissing his mouth, tasting himself in Katsuki’s tongue, and when he grips the length between Katsuki’s legs, it takes five pumps before the blond’s gasping against his lips, shooting cum up to Shouto’s chin.
Katsuki rests his forehead on Shouto’s neck, both of them breathing erratically, when they hear Izuku squeak. They turn to look just in time to see Izuku coming a second time, his own hands wrapped around his cock, painting his belly with hot cum. Katsuki smirks against Shouto’s throat.
“Enjoyed the view, baby?”
Izuku groans. “Are you kidding? That’s the hottest thing I’ve ever seen!” he responds, and Katsuki chuckles fondly, pulling him to them.
All three of them lay sprawled across the bed once more, limbs entwined in a chaotic heap, utterly spent. Shouto feels his eyes closing, despite everything—despite being morning, despite being disgusting, despite not being in his bed.
He feels a profound sense of security, wrapped up in limbs that aren’t his own, heart swelled with warmth and affection. He presses his lips against pale blond hair and whispers, “I love you,” delighted by the way Katsuki blushes and stops complaining about their state. Shouto turns gently, this time pressing again tangled curls, and repeats, “I love you,” aching at the sight of tears dropping steadily from huge green eyes, hearing a soft sniff as Izuku holds back his cries.
Both Katsuki and Izuku echo back to him, their voices tentative yet filled with the same warmth spreading through Shouto:
“I love you.”
Nestled in the warmth of their embrace, surrounded by their tangled bodies, nothing had ever felt so perfect.
