Work Text:

All the lights are off, with only the flickering glow from the TV hitting them. At the other end of the room, Kirishima is leaning back on the long sofa and snoring loudly, while Mina and Ochaco are passed out on the floor in front of the coffee table.

The two are tucked into the very corner, hidden under a thick blanket. The blonde is slumped against the armrest, his legs kicked out to make space for the smaller boy backed up flush against his chest. They look like they’re just cuddling, but it’s been getting way too intense for over an hour now. 

It started small. Just fingers ghosting under the hem of a shirt, tracing ribs until the younger boy’s breath hitched. “K-Kacchan…” he whispers, his spine arching instinctively. But the hand doesn't stop. It slides lower, until a warm palm finds the damp fabric of sweatpants covering Izuku’s aching cunt. 

He doesn’t rush. He just pets him through the thin cloth, his hand heavy and steady. It’s enough to make the younger’s head fall back onto his shoulder, and his knees dropping open to give his boyfriend better access. Every time that palm presses down, Izuku grinds his hips back into the touch, his body searching for the friction of those calloused fingers against his pussy. 

Then the blonde shifts his focus. His thumb finds that swollen, sensitive nub through the wet fabric and starts rubbing in tight, perfect circles. It’s too much. Izuku’s back snaps into an arch, a loud moan climbing up his throat, ready to wake the whole room.

Katsuki’s faster, though. He hooks two fingers under the boy’s chin, forcing his head back at a sharp angle. He leans down and smothers the sound instantly, his mouth crashing against his lover’s in a deep, hungry kiss. He swallows the moan whole, his tongue sweeping inside to taste the heat while the younger melts against him, body shaking from the double sensation of the kiss and the hand grinding below.

Izuku whimpers into his mouth, his tongue shyly tangling with his as he tries to keep up. He’s breathless, but he just leans further back, exposing his throat and begging for more.

A sharp nip to his bottom lip makes his hips jerk violently against the hand still working him. The kiss gets wetter and louder, the sound of their lips sliding together is barely hidden by the TV. Katsuki catches the younger’s tongue between his lips and just sucks on it, a drawing pressure that melts Izuku. 

Every time the smaller boy tries to gasp for air, Katsuki just realigns their mouths and seals them shut again. He’s literally drinking in every shuddering breath, making it impossible to pull away. Saliva glints on their lips in the TV light, trailing down a chin as they break for a fraction of a second, only for him to dive back in, completely possessive. It’s a kiss that says you’re mine, and Izuku just clings to his arms, taking every bit of it.

Katsuki’s patience finally snaps. He doesn't care about the movie or the people sleeping just a few feet away anymore. He maneuvers the smaller boy until he’s straddling his lap, facing him. The blanket shifts but stays low, hiding them. Through the layers of their sweatpants, his heavy bulge hits that wet, soaked pussy directly. 

“Nghhh…K-Kacchan, someone might..." the boy whispers, his voice breaking as he feels the sheer size of the bulge beneath him. Even in the middle of this mess, he leans in and nuzzles his nose against the blonde’s, a tiny, affectionate habit that almost makes Katsuki lose it.

He doesn’t let him finish the thought. He pulls Izuku into a deep, aggressive kiss, sealing their lips to swallow the sounds of his arousal. The younger boy melts, his mouth sucking the blonde’s tongue as he tries to be quiet. A large hand digs into his backside, fingers clenching and forcing him down hard, making sure that his cock grinds as deep into his boyfriend’s pussy as the fabric allows.

The atmosphere is thick enough to choke on. Every time Katsuki drives his pelvis upward, the soaked fabric of their clothes meets with a heavy, wet sound that echoes in the dark. He’s stopped being careful, his humps coming in hard force that Izuku has to stifle a scream against his shoulder.

The blonde grips his boyfriend’s chin, forcing that flushed, ruined face upward. “You’re making so much fucking noise down there, Zu. Does it feel good getting worked like a slut while our friends are right there?” he whispers teasingly.

The younger boy is a total wreck, yet he remains so incredibly sweet. Even as his mind begins to melt, he leans in, peppering quick, apologetic kisses against the blonde’s jaw and the corner of his mouth. His breath hitches in warm, shaky stutters, like he’s struggling to hold himself together.

He’s trying his absolute best to be good and stay silent for the sake of their friends nearby, but the moment those calloused hands slide beneath his shirt to grip his waist with bruising force, all his resolve vanishes. The friction between them shifts from a slow burn to something frantic and urgent, a desperation that he can no longer ignore.

“Nnh… K-Kacchan, please… it’s too much,” he whimpers, his voice cracking. “Sorry, I’m so messy… I’m all yours. Please, just don’t stop.”

The blonde’s fingers under the green shirt are digging into the boy’s waist so hard they’ll definitely leave marks. “Say it, baby. Tell me whose pussy is soaking through these clothes,” he growls, his teeth nipping at a reddened earlobe. 

“Yours… it’s yours,” he cries out silently, the words muffled against the blonde's shoulder. “I love you, Kacchan… I love you so much.”

Izuku is completely falling apart, his movements becoming desperate and uncoordinated as he chases the friction. Despite the filthiness of it, his hands reach up to cup the blonde’s face with a tenderness that’s almost painful. His thumb brushes a damp cheekbone, even as he jerks his hips forward in a frantic plea for the grind to get harder, deeper, faster. He’s chasing the feeling of belonging entirely to the man holding him.

He forces his eyes open, searching for crimson, and when he finds Katsuki’s gaze, the world narrows down to just the two of them. They are staring at each other with a raw, desperate hunger that goes beyond the physical. Their breaths begin to sync, with shared desperation to feel, and to own.

Katsuki’s teeth sink into the boy’s shoulder, not to hurt, but to muffle his own jagged breathing. He’s moving his hips in short, agonizingly slow circles, trying to keep the wet sound of their soaked clothes from becoming a loud sound that might wake the others.

“Fuck… Stay quiet, Zu” he breathes into the crook of a sweaty neck. “Unless you want everyone to see how much of a mess you’re making of my lap.”

The younger boy is practically vibrating, his teeth clamped down hard on his lower lip to keep the whimpers from escaping. He’s so desperate for a real kiss, something to muffle the frantic sounds he’s making, but he is met with a smirk instead.

“Kacchan...Kiss, please,” he breathes, the whisper barely a ghost of a sound. He leans in, seeking those lips, but the blonde just tilts his head at the last second, burying his face in the crook of a sweaty neck.

“I am kissing you, baby,” he murmurs, his hot breath making the boy’s toes curl.

“Ngh... no, no, please,” the younger boy whimpers, his head tossing back.

To prove his point, Katsuki drags his tongue lazily from Izuku’s collarbone all the way up to his earlobe, followed by a series of tiny, biting nips along his jaw. It’s sweet, almost playful, if it weren’t for the way his lower half is ruthlessly snapping upward.

“Kiss, kiss me… please?” Izuku’s eyes are completely glazed over, his pupils blown wide with lust. His hips frantically grind down into the blonde’s lap with a desperate, heavy pressure.

Katsuki’s heart is slamming against his ribs, nearly matching the frantic pace of the boy on his lap. Izuku’s a total wreck, and the blonde is right there with him, his own arousal hitting a painful, hard peak that makes his vision go a little blurry. 

He loves seeing his Izuku like this, with his eyes glazed over, mouth hanging open, and hips working with that desperate rhythm. Katsuki’s obsessed with it. He loves knowing that this sweet, selfless hero could only ever be this desperate and filthy for him. Only for him. Always just for him. For the rest of their lives.

They are dry humping with a raw intensity, their bodies slamming together as if they’re trying to merge right through the fabric. The only thing keeping this from being full-blown sex is the thin barrier of their clothes, but even those are failing. The dark patches on both their sweatpants are undeniable proof of how bad they want this.

“Kacchan... Kacchan…” Izuku has lost the ability to form sentences, his voice nothing but a broken chant of that name. His grip on Katsuki’s shoulders is strong, while the blonde’s  arms wrap around that small waist, hauling him flush against his chest to make the grinding even more punishing.

“Please… please,” the smaller boy whimpers, his head lolling back as he actually sticks his tongue out, a silent, shameless invitation for Katsuki to take it.

It’s filthy, and they both know it. The moment Izuku offers his tongue, Katsuki lets a thick string of spit fall onto it. The younger boy doesn’t even flinch. He knows exactly what to do with the gesture. He swallows it down, his throat working as he tastes the blonde, before sliding his tongue back out again, pleading and anticipating for more, and Katsuki indulges him…again and again. 

“I’m close,” Izuku whimpers, his voice cracking as his eyes well up with fat, shaky tears. The friction of that hard cock against his soaked pussy is finally pushing him over the edge. 

“Go on then, baby,” Katsuki murmurs, his voice a low vibration that Izuku feels right in his bones. The blonde watches his nerd fall apart, how he is quirming and twisting on his lap, completely lost. “Keep going. Don’t you dare stop grinding that pretty little pussy on me.”

“I can’t... It’s too much! Kacchan! Please, I’m gonna—” He’s actually sobbing now, a tiny, pathetic sound that he tries to swallow against a trembling hand.

The blonde just chuckles and sinks lower into the sofa, spreading his legs wider to anchor the boy in place. He takes over the movement, his pelvis snapping upward in heavy, vertical thrusts that hit that sensitive spot with brutal precision.

“Just a little more, Zu... Come on... fuck,” the blonde growls. 

Suddenly, Kirishima stirs on the other side of the room. He lets out a long, sleepy groan and shifts, his arm flopping over his face. Both Katsuki and Izuku freeze, holding their breaths, and hearts slamming against their ribs in the terrifying silence. For a few agonizing seconds, the world stops. 

Then, the snoring resumes. 

Katsuki feels a rush of pure adrenaline. The risk makes him meaner, hungrier. He clamps his hands down on that small waist, his grip is bruising and possessive.

“Kacchan! Hnggh...”

A long, choked moan breaks out as the boy starts to shake violently. He tries to scramble off, his hands pushing at the blonde’s chest in a desperate attempt to escape the pleasure that’s becoming too much to handle. Katsuki pins him down on his hips, forced to take every bit of that heavy pressure.

“You’re so loud,” Katsuki moans, his own composure snapping. “Listen to that... listen to how wet you are for me.”

He looks like a sweetheart being absolutely ruined with eyes rolled back, tongue peeking out, thrashing in a frantic attempt to find relief. The blonde keeps humping into him, relentless and heavy, even as the boy begins to shake with the first violent tremors of a climax.

Katsuki loves watching his boyfriend cum. The way the boy’s body goes rigid, the way he tries to fight it and crawl away while his voice breaks into those tiny, high-pitched whimpers. Katsuki never lets him go, though. He just grinds deeper, forcing him to feel every inch of that hardness right as he spills over.

The blonde waits for the shaking to subside just enough, but he isn’t done with him yet. He reaches up, his fingers tangling in those messy green curls to tilt the boy’s head back again. He wants to see that dazed, ruined expression. 

“Look at you,” he whispers, “Cumming like a little brat while our friends are right there. You want that kiss now, sweetheart?”

The boy can only nod weakly, his lips parted and glistening. He leans with a soft, needy whimper, his eyes fluttering shut in anticipation. The blonde crashes into him, swallowing his breath whole, turning the kiss into something hungry and deep.

Then, he gets mean with it. He catches the boy’s tongue between his lips and begins to suck on it, a slow, drawing pressure that feels like he’s trying to pull the soul right out of him.

“Nnnph!” The boy’s eyes fly open, his pupils blown so wide they’re almost entirely black. The sensation is intoxicating. The blonde’s tongue swirling around his, pulling it into his own heat over and over. Every time he draws the younger’s tongue deep into his mouth, his boyfriend’s hips jerk upward instinctively, his pussy slamming back down into the blonde’s lap in a desperate, uncoordinated search for more friction.

Izuku is no longer satisfied with the muffled friction of thick fabric. Every pulse and throb between his legs was a frantic itch that only Katsuki could scratch, that only his Kacchan is allowed to. There’s a heavy heat inside him that made his skin feel too tight. 

It is as if they were sharing the same desperate thought, because Katsuki’s hands fumble at Izuku’s waistband, his voice a low command. “Zu, lift up a bit… get these pants down.”

Driven by a surge of raw, impatient need, Izuku yanks his sweatpants and underwear toward his knees. He doesn’t bother taking them off completely; he just needs them out of the way, exposing his slick, aching pussy to the hot air under the safety of the blanket.

Katsuki didn’t waste a second, hitching his own hips up just enough to shuck his sweatpants and boxers down, finally freeing his own hard cock to meet the heat he’d been craving. 

Digging his fingers deep into the meat of Izuku’s thighs, Katsuki hauls him down, forcing his boyfriend to take his full weight right against his erection.

Izuku groans, immediately dropping his weight and grinding his hips forward in a heavy, desperate smear. He humps down hard, wet folds sliding and sliding over the length of Katsuki’s cock before he hitches himself up just enough to do it again. The squelching sound of their combined fluids trapped between their bodies is loud and undeniable under the blanket. 

“Shit…listen to that, baby. You’re fucking dripping.” Katsuki’s breath is coming in ragged, harsh gasps. His hands move from Izuku’s waist to the meat of his ass, gripping the flesh tightly and pulling the younger down even harder against him. He bucks upward with a sudden jerk of his hips, driving the hard length of his cock firmly between the younger boy’s pussy lips, catching his clit. 

“I can’t help it,” Izuku sobs out, hitching his hips up just to grind down even harder, the friction making his head spin. “You make me so wet, Kacchan.” He lets out a fractured cry, his toes curling into the sofa as the intense, relentless rubbing pushes them both dangerously close to the brink.

Then, the blonde shifts their weight, moving into a sitting position that faces the rest of the dark room. With a firm grip on Izuku’s waist, he maneuvers him to sit directly on his lap, also facing forward with his back on Katsuki’s chest. 

The younger boy adjusts himself, his knees bracketing his boyfriend’s hips as he settles down onto him. They’re a tangled, breathless mess, but the heavy blanket remains draped over them.

The blonde immediately slides his hands between Izuku’s thighs, moving with a hungry intent. Using the fingers of one hand, he firmly grips and spreads the soft folds of his cunt, pulling them wide. The motion leaves the smaller boy’s clit and his very core completely exposed. His pussy is flushed in a deep, angry red and trembling with sensitivity in the air under the blanket.

He doesn’t give him a moment to adjust. Katsuki focuses his other hand entirely on that swollen clit, rubbing it with a heavy, relentless pressure. Every so often, his nails scrape lightly against the nub, a sharp spark of friction that borders on pain. It hurts so good that the younger boy can’t help but sob quietly, his breath hitching as he tries to stay silent. 

Katsuki’s fingers dive lower, seeking out that tight, throbbing cunt that’s already slick and weeping for him. He doesn’t ease in; he drives two fingers deep, finding the rhythm instantly. He begins to pump them in and out at a punishing, agonizingly fast pace, the wet slap of his palm hitting Izuku’s skin muffled only by the heavy blanket.

“Nnngh!” Izuku's head is tossing wildly.

“That’s it, take it,” Katsuki moans, his own breath hitching as he hooks into the soft folds, pulling Izuku open as wide as he can go. He wants the younger to feel every bit of the friction, leaving him completely exposed and vulnerable to the relentless stretching. “Shit… you’re so wet. Listen to that… you’re literally splashing against my hand. You’re gonna soak through the cushions if you don’t stop.”

“Ah… it’s too much—hnggh. It feels too good… Kacchan, deeper. Please, just… ohhh…”

Izuku’s head falls back against the blonde’s shoulder, tears tracing hot paths down his cheeks. His toes curl tightly, overstimulated by the sheer intensity of the pleasure. The blanket is their only shield, draped over their shoulders to hide the intimacy from the rest of the room. But with every frantic movement of Katsuki’s hand, the fabric shifts and ripples, barely disguising the filth they’re indulging in right under their friends’ noses.

“Our friends are right here, and you’re being so loud. Don’t you care if they wake up and see you like this, baby?” Katsuki’s voice is a low, dangerous rasp against his ear, mocking and possessive all at once. 

“Hngh! I—I do care,” Izuku stutters, his fingers digging into Katsuki’s arms as he tries to remember they aren’t alone. “But it feels—nghh—it’s too much. This feels so good, Kacchan.” 

His breath hitches as those fingers stretch him further, the sharp thrill of pleasure mingling with the terrifying adrenaline of nearly being caught. His body betrays every effort at silence, arching helplessly into the touch, begging for more. He is completely undone, trembling with a desperate need to just let go.

Every time Katsuki’s fingers hook upward, they catch his g-spot with a ruthless accuracy that makes Izuku’s vision go white.

“Deeper, please… just a little deeper.”

Katsuki obliges, sliding a third finger inside and curling them into a hook, relentlessly punishing the exact spot that makes Izuku come apart.

“There! Nghhh, Kacchan, right there… don’t stop, please…”

“Right here, baby?” Katsuki taunts, his voice dropping. “Should I keep hitting it right here?”

“I’m near... I’m so close, Kacchan...”

“Already? You’re going to squirt for me, pretty boy?”

God, Katsuki would give anything to pull back the covers and watch him cum, but the weight of their sleeping classmates in the room keeps the blanket firmly in place.

“Should I pull the blanket back, huh?” Katsuki murmurs, his lips brushing against the smaller boy’s flushed earlobe. “Let everyone see what a leaky little brat you are? Let ‘em see exactly how wide I’ve got you stretched while you’re spraying all over the cushions?”

“No, no—please, don’t—” Izuku’s head shakes frantically, his breath coming in ragged pants as he clenches tightly around Katsuki’s hand.

“Hm? You don’t want them to see?” Katsuki teases, his fingers curling upward to hook deep against that sensitive spot. “Even though you’re being so loud for them?”

“I don’t,” Izuku gasps, his body jolting like he’s been struck by lightning when Katsuki’s thumb presses firmly against his swollen, aching clit. The sensation is so sharp, so sweet, it brings tears to his eyes. He buries his face deep into the crook of the blonde’s neck, hiding his burning face. “Only you... I only want you to see me like this, Kacchan. Please... just you.”

The confession earns him a low, satisfied growl. Katsuki leans in, his tongue darting out to lick a salty tear from Izuku’s cheek before his fingers begin to move again, faster and filthier than before.

The boy’s eyes roll back as his body finally shatters under the weight of the pleasure. He’s completely undone, his walls clenching in a tight, rhythmic pulse as his hips buck upward, desperate to pull those fingers even deeper against his pussy. 

“Ahh… Hngghh Kacchan! It feels so good…”

“Yeah? You like being stretched out like this?” Katsuki growls, his voice a low, gravelly vibration that cuts through the quiet of the common room. He watches with hungry, possessive eyes as Izuku begins to tremble uncontrollably. “Look at you. You’re fucking shaking. You can’t even hold it back, can you?”

A loud moan breaks from the younger boy as he begins to tremble uncontrollably. He clings to his boyfriend with a bruising grip. His entire frame shudders as wave after wave of release crashes through him, forcing jets of hot, slick fluid to spurt from his pussy. 

“Fuck, Zu, look at that,” Katsuki gasps, his own breath hitching as he feels the heat of the spray hitting his hand. “You’re flooding the goddamn sofa. You’re making such a mess for me. Listen to that splashing. You’re fucking soaked, baby.”

The heavy blanket is the only thing saving them now, soaking up every last drop of the younger’s squirt. If it weren’t for that single layer of fabric, the common room carpet would be drenched, leaving a mark that no amount of explaining could ever cover up.

Izuku’s strength completely fails him. His head drops heavily onto Katsuki’s shoulder, his forehead damp with sweat as his body continues to hum with the aftershocks of his release. Under the safety of the blanket, the blonde doesn’t pull away. Instead, his thumb continues its relentless circling against Izuku’s sensitive clit, coaxing out every last drop of liquid. The younger can only part his lips in a silent gasp, too far gone to do anything but drift.

Katsuki leans in, pressing a brief, grounding kiss to the boy’s temple.

The silence is shattered by the rustle of fabric. “Mido fell asleep, huh?” Kirishima’s voice is groggy, cutting through the heavy atmosphere like a blade.

Izuku jolts, his heart leaping into his throat, and he buries his burning face deeper into the crook of the blonde’s neck, praying the darkness hides the feverish flush on his skin. To any outside observer, they are merely two figures tangled together in the exhaustion of the night. 

But Katsuki was fueled by the thrill of the risk. Instead of pulling away, he hooked a third finger deep into that weeping, over-sensitive heat, his thumb pinning Izuku’s clit with a heavy, grinding pressure.

“Mmh—!” The moan was nearly lost against Katsuki’s pulse. Even with Kirishima staring right at them, his hand doesn’t stay still under the blanket. He keeps rubbing, a relentless friction that makes Izuku’s breath hitch. The younger boy manages to swallow a moan, but his body betrays him, his hips lifting in a small, helpless hump against Katsuki’s hand.

The squelch of friction is deafening to Izuku’s ears. He’s certain Kirishima can hear the wet, messy sound of Katsuki’s fingers working him over.

“Man, he must be really tired,” Kirishima mutters, his voice drifting dangerously closer as he stands up to stretch. “He’s shaking.”

Izuku freezes, his muscles locking in a panicked clench around Katsuki’s hand, but the blonde only uses the added tension to grind deeper.

“Yeah,” Katsuki rasps, his voice low and steady. He doesn’t stop his movement, his thumb just presses harder on his boyfriend’s clit. “The nerd’s out cold. Shut up and go back to sleep, Shitty hair.”

Kirishima groans, shifting his weight with a loud yawn. “Lucky guy. I wish I could pass out like that. This couch is killing my back. I’m gonna head up to my room.”

He stands up, the floorboards creaking under his feet as he stretches. He’s standing only feet away, oblivious to the fact that beneath the fabric of the blanket, Izuku is currently melting into Katsuki’s touch. 

The sound of Kirishima’s footsteps fades down the hallway, leaving behind a silence so heavy it feels like it might shatter. As the immediate threat vanishes, a new, sharper realization hits Izuku like a bucket of ice water, slicing through the haze of his arousal. He had been so focused on Kirishima that he’d forgotten the room was still occupied.

“K-Kacchan... stop,” Izuku whimpers, the plea barely a thready vibration against the blonde’s collarbone. He tries to pull back, but his muscles are too weak to do more than tremble. “Mina... Ochaco... they’re still right there.”

“Exactly. They’re right there,” Katsuki breathes, his lips grazing Izuku’s damp forehead. His voice is a low, predatory hum. “If you make a sound now, they’ll wake up to see exactly what I’m doing to you. They’ll see how much you’re enjoying this.”

He doesn’t give the smaller boy a second to breathe. His hand, already slick with the evidence of Izuku’s first collapse, slides back down. Instead of a caress, he begins to rhythmically slap his open palm against Izuku’s weeping, overstimulated core. The heavy, wet sound of the impact is muffled by the blanket, but the sensation is a violent jolt of electricity that shoots straight to the younger boy’s brain.

Katsuki leans in, his teeth grazing the shell of Izuku’s burning ear. “You’re so wet, baby. You love them being here, don’t you? Knowing they could see you like this?”

“No... nghh... please…” Izuku’s head falls back, his throat bared and trembling, his eyes clouded with a mix of shame and agonizing need.

The blonde ignores the plea, increasing the pace of those heavy, stinging strikes until the friction is a blur. The younger boy’s toes curl into the sofa cushions, his fingers digging into his boyfriend's forearms until his knuckles turn white.

“Come on,” Katsuki rasps, his own composure finally fracturing as he sees Izuku’s pupils blow wide. “Do it for me, nerd. Stay quiet and give it all to me.”

The overstimulation is excruciating. Izuku bites down on his own lip so hard he tastes metallic tang of blood, his eyes wide and watering as he stares at the silhouettes of his friends just feet away.

Katsuki leans back just enough to catch his boyfriend’s gaze, his expression dark and starved. He delivers one final, firm slap directly against Izuku’s throbbing clit. His hips jerk reflexively, trapped between the blonde’s grip and the suffocating weight of the blanket. The tension snaps at a terrifying speed.

“Don’t you dare scream,” Katsuki warns.

The world shatters. Izuku’s back arches off the blonde’s lap, his head snapping back as he loses all control. He swallows his scream, the sound dying in a series of tiny, pathetic hitches in the back of his throat. His entire body goes rigid, toes curling into the fabric of the sofa as his pussy clenches.

With Izuku still shivering and limp in his arms, Katsuki slowly withdraws his hand from beneath the blanket. His fingers are drenched, glistening in the dim light from the TV. He doesn’t wipe them away. Instead, he holds his index and middle fingers up to his face, watching with satisfaction as a string of Izuku’s slick slides down his knuckle.

Without breaking eye contact with the dazed boy, Katsuki brings his fingers to his lips and licks them clean with his tongue, tasting the salt and heat of his boyfriend’s climax 

“You taste so fucking good, baby,” he murmurs, his voice a low, rough vibration that makes Izuku’s breath hitch all over again.

Katsuki doesn’t wait for a response. The adrenaline is still humming in his veins, but the risk of staying in the common room has reached its limit. He needs his baby behind a locked door.

With practiced movements, he gathers the blanket and wraps it tightly around Izuku, cocooning him in the warm fabric to hide his flushed skin and trembling limbs. Katsuki tugs his own sweatpants back up, settling them over his hips.

The blonde ignores the soft snores of the girls on the other side of the room, his gaze fixed solely on the hallway. His footsteps silent on the carpeted halls. When he finally reaches his door, he nudges it open with his shoulder and slips inside, the soft click of the lock acting as the final seal on their secret. 

Finally, behind closed doors, he can have Izuku. 

Katsuki strips them both bare with frantic, impatient hands. He settles against the headboard, and Izuku climbs onto his lap, facing him. Izuku’s thighs are spread wide, bracketing his boyftiend’s hips as he settles over him.

“Can I suck you first, Kacchan?” Izuku whispers, his voice thick with a desperate need to please.

“Huh? You want to suck me? When your pussy looks this hungry for my cock?” The blonde’s possessive hunger flares at the sight of his boyfriend’s body. He reaches down, grabbing Izuku’s thighs and pulling them further apart, his fingers hooking into the soft flesh to spread him wide, exposing his soaking pussy to the light.

“But... please? Fuck me later, Kacchan…”

“Next time, Zu. I badly want to get inside you right now.” The smaller boy whimpers, lifting himself just enough to align his heat with the tip of Katsuki’s length.

“Slowly…I want to see exactly how you open up for me,” Katsuki orders.

Izuku’s eyes blow wide and his mouth hangs open as he feels the head of Katsuki’s cock breach his tight, soaking cunt. With every inch that the younger boy sinks down, Katsuki watches with dark intensity as the flushed pussy lips stretch to accommodate him. Because Katsuki is holding him open so wide, nothing is hidden. 

Once he’s buried to the hilt, Izuku begins to grind. Gravity pulls him down harder, making every seat deeper. Each bounce and roll of his hips produces a loud, filthy slap of skin that echoes through the room.

“Ah—! K-Kacchan, l-look…” Izuku moans, his own gaze dropping to watch the way his body is greedily swallowing Katsuki whole. 

Desperate to show him even more, the smaller boy leans back until his spine arches, his hands catching Katsuki’s muscular thighs to anchor himself. The movement forces his knees further apart, stretching him to the absolute limit. In the warm glow of the lamp, he offers his boyfriend an unobstructed, filthy view of the intrusion.

“See?” Izuku gasps, his head lolling back as he feels the slick, wet friction of himself being filled to the hilt. “See how much… nghh… how much you’re stretching me, Kacchan? I’m so full…”

He grips Izuku’s waist with a bruising intensity, his knuckles white as he drags him down with punishing force. His other hand remains relentless, hooked into the soft folds to keep Izuku spread and completely, shamelessly exposed to the cool air and his own hungry gaze.

“I see it, baby. God, I see all of it,” Katsuki rasps, his voice thick with a dazed, predatory heat. He watches with wide, mesmerized eyes as his boyfriend’s pussy milks his entire length, the sound of it turning thick and slapping. “You’re such a good little slut for me... look how much you’re leaking while I watch.”

The final threads of sanity snap within the confines of the room. In his cowgirl position, Izuku’s pace becomes feral, his hips moving with a frantic, inhuman speed as he chases his release.

Every time the younger boy slams down, the room fills with the sharp, rhythmic crack of skin meeting skin. Katsuki watches with a starved intensity as Izuku’s swollen, bruised pussy greedily devours and spits out his length.

“K-Kacchan! I ca—shit, I can’t stop!” Izuku screams, his eyes rolling back into his head as his fingernails dig deep into Katsuki’s thighs, drawing white crescents in his skin.

With one final, punishing upward thrust from Katsuki met by Izuku’s desperate downward collapse, the younger boy’s body finally shatters. His core clenches so violently it forces a hot, heavy spray of fluid to erupt from him. The squirt hits Katsuki’s chest with force, droplets splattering across his neck and lips.

“Fuck!” Katsuki growls, his eyes narrowing as he feels the searing heat of Izuku’s pussy juice coating his skin. The sensation of being literally drenched by the nerd is enough to make him cum. With a guttural, animalistic groan, Katsuki’s own body gives way. He thrusts one last time, pinning his boyfriend down as he pumps his seed deep into that pulsing, sobbing pussy in hot, heavy bursts.

But Katsuki’s hunger is far from sated. Even as Izuku continues to shudder and twitch from the force of his orgasm, his hands move with a violent possessiveness. He grabs the nerd by the waist, hauling his limp, boneless body forward until Izuku is straddling his head, forced to sit directly over his face.

“Make your mess right here on my face, baby,” Katsuki commands.

Izuku can only let out a fractured, high-pitched sob, his fingers clutching blindly at the headboard as he’s held on display. Without a moment’s hesitation, he buries his tongue deep into Izuku’s drenched, weeping cunt.

He swirls his tongue through the messy mixture of his own cum leaking back out of Izuku’s pussy and the boy’s own sweet, salty juices coating his jaw. He drinks it all in, devouring every bit of the filth they just made together.

Each stroke of the blonde’s tongue is deliberate, lapping at Izuku’s engorged clit as he scavenges for every last drop of their combined fluids. The smaller boy lets out a ragged, broken shriek, his thighs trembling uncontrollably atop his boyfriend’s shoulders. The sensation of that hot, wet muscle cleaning him out like a starving animal is too much for the poor boy. 

The air in the room is thick, heavy with the cloying scent of sweat, spilled cum, and Izuku’s own arousal. With every suction, lick and sharp nip the blonde delivers to his most sensitive nerves, the younger boy feels himself being dragged into another round of overstimulation that feels like it’ll never end.

Katsuki is completely indifferent to the mess coating his face; the smear of his own seed and Izuku’s slick only fuels his hunger. As Izuku is pinned in a desperate facesitting position, Katsuki’s fingers bury themselves deep into the flesh of his boyfriend’s ass, brutally spreading his cheeks wide to shove his face even deeper into the center of his pussy.

The blonde’s tongue is wide and punishing. Every drag from the base of Izuku's entrance up to his engorged clit is accompanied by a loud, filthy suction fills the quiet room. 

“K-Kacchan! S-Stop—it’s too much, hngh!” Izuku’s spine arches like a bow, his fingers tangling desperately in Katsuki’s blonde spikes as he involuntarily grinds his core harder against the man’s mouth.

But Katsuki only accelerates. His tongue darts out like he’s trying to force his way inside Izuku’s pussy, mashing the sensitive clit between his lips and teeth. Driven by a sudden impulse, while his tongue is fucking the younger’s pussy, he slides one hand down. Without a word of warning, the older boy plunges a finger deep into Izuku’s tight asshole. 

“A-AH! K-KACCHAN!” Izuku screams, his entire body snapping straight and seizing in a violent tremor. He never expected the sudden, invasive stretch while his front was still being eaten out. 

The intrusion is blunt and uncompromising, stretching Izuku open in a way that makes his head snap back. Katsuki doesn't give him a moment to adjust; he begins to hook his finger, curling it deep inside that makes Izuku’s entire lower half shudder.

“K-Kacchan! Please—I can’t—” Izuku chokes out, his hands clawing at the older’s blonde hair. 

He remains ruthless, driving a second finger in beside the first. He spreads the boy wider, his knuckles grazing the rim with every heavy, fast-paced plunge. He can feel Izuku’s internal muscles clenching in a frantic, panicked pulses, trying to swallow the intrusion whole.

The double penetration sends Izuku into a total sensory blackout. His focus splinters between the searing, wet friction at his front and the heavy, intrusive stretch at his back. His brain short-circuits; all he can process is how utterly ruined and wide-open he is, pinned and defenseless under Katsuki’s merciless command.

The blonde refuses to let him escape. Every time Izuku tries to get away from the sensitivity of it, the blonde’s grip on his ass tightens, bruising the skin as he hauls Izuku’s heat even deeper against his face. His breath hitches into a heavy, muffled growl against Izuku’s inner thighs, each lap of his tongue becoming sloppier, and more desperate.

Between the wet, rhythmic violation of Katsuki’s tongue at his front and the unrelenting hammer of a finger at his back, Izuku unravels. He can’t stay seated because the pleasure is too much. 

“Wait—too much! I’m gonna—!” Izuku’s voice breaks into a sob as he lunges forward, collapsing into a desperate arch, his knuckles turning white as he grips at the headboard for leverage while his hips are hiked shamelessly high into the air.

Katsuki doesn’t miss a beat. He drops to his knees behind his boyfriend, his large, calloused hands reaching out to claim what’s his. He hooks his fingers into the soft skin of Izuku's thighs, pulling them wider, before his thumbs find the damp, swollen folds of his labia. With a slow, deliberate motion, he peels them apart. 

From this angle, everything is shamelessly exposed. With the folds held open, the deep, dark pink of Izuku’s pussy is laid bare, glistening and raw from the friction. He’s so overstimulated that the delicate walls are visibly pulsing, leaking a steady stream of cum and slick that coats Katsuki’s thumbs. 

Katsuki lets out a low hum at the sight before burying his face back into that weeping heat. With one final, punishing lash of the blonde’s tongue against his swollen clit, the smaller boy tenses. His legs seize violently, his muscles coiling and snapping under the weight of another climax.

“KACCHAN! PLEASE!” Izuku screams, his voice breaking as he loses all control.

As the raw wail tears from his throat, his pussy pulsates rhythmically. Because he is arched and helpless, the hot liquid erupts in a powerful jet, drenching the bed like a burst dam. Katsuki’s pristine white sheets are instantly ruined, soaking up Izuku’s release.

“That’s it... fuck, drown the bed for me,” Katsuki moans. He grips his length with a heavy, bruising fist, stroking himself into a frantic up and down motion while his eyes locked on Izuku’s twitching, overstimulated pussy. 

The younger’s body continues to spasm and writhe in the aftershocks. Each deep, internal throb of his core sends more fluid arching out, splattering across the bed. The sound of the liquid hitting the fabric is loud and filthy.

Katsuki is far from finished. Even as Izuku collapses against the headboard, his limbs twitching with exhaustion, the blonde hauls him back up. He forces Izuku to find his footing on the mattress but keeps him bent cruelly forward, his trembling hands forced to grip the headboard just to stay upright.

“K-Kacchan... no more... p-please…” Izuku sobs, his voice coming out in tiny, pathetic puffs of air. “I-it’s too much... ‘m g-gonna break..."

But Katsuki is fueled by a mix of adrenaline and pure, unadulterated lust, so he doesn’t have an ounce of mercy left in him. Using his massive hands, he grips Izuku’s inner thighs, bruising the soft skin as he wrenches them open even wider.

“Just a little more, Zu. Be a good little faucet for Kacchan and show me how much more you’ve got.” 

He presses a thumb directly onto Izuku’s engorged clit and gives it a sharp, merciless grind. A violent tremor racks Izuku’s entire frame. 

“NO! K-KACCHAN, STOP! H-HNGHHH!” The scream dies in his throat, turning into a high-pitched, mewling whine as he tries to shy away from the pleasure. His back arches so hard his ribs poke through his skin.

He doesn’t give in yet. Instead, he aligns the broad, blunt head of his cock against the center of that cunt, deliberately dragging his tip from the bottom of the leaking entrance all the way to the swollen, twitching peak of Izuku’s clit. He paints the length of the weeping folds with his own pre-cum, watching with a predatory focus as the dark pink entrance clenches and spasms around thin air, hopelessly begging to be filled.

He does it again, harder this time, catching against Izuku’s clit before dipping back down. But then, he shifts his weight, his thumbs hooking into the smaller boy’s hips to hold him steady. He doesn’t plunge in; he just forces the head past the tight, clenching entrance.

Izuku lets out a strangled, broken sob as he’s stretched wide by just the tip, his walls desperately trying to suck the rest of that heat inside. Katsuki just grunts, pulling back until he's almost out, then shoving the tip back in again and again. 

The wet, tacky squelch of the friction is deafening. Katsuki watches the way Izuku’s hips instinctively buck upward, trying to impale himself, but the older just keeps it shallow.

“You like that, don’t you?” Katsuki hisses, watching the way Izuku’s walls desperately try to suck the rest of him inside. “Just the head, Zu. Look at how much you’re leaking just for the fucking tip. So fucking desperate for the rest of me.”

He punctuates the words with a series of fast, shallow stabs, never going more than two inches deep but hitting the entrance with enough force to make Izuku’s teeth rattle. His voice reduced to a series of high, needy whimpers as he starves for the weight he’s being denied.

Then, Katsuki’s patience finally snaps. Without a single word of warning, he delivers a brutal, bottoming thrust, burying his entire length back inside Izuku in one go. 

“A-AH! Kacchan... wait,” Izuku’s head snaps back, his eyes rolling into his head as he slides further into a total sensory blackout. His vision flares with white spots. The only sound in his ears is the wet, slapping of their bodies colliding.  “Too much... it’s—it’s too big, I can’t—” 

“Too much, huh?” Katsuki mocks, then he leans down, burying his face in the crook of Izuku’s neck, “You’re such a pathetic little liar, baby. You’re shaking so hard, but you’re squeezing me like you never want me to leave.”

Despite his weak protests, his body betrays him, his walls clamping down in a death-grip around Katsuki with every shove. He loses the strength to even form words, reduced to nothing but soft, kittenish whimpers and shaky, hitching breaths as Katsuki ruthlessly works him over. 

“Stop fighting it and just take it. You know damn well you were made to fit me exactly like this.” 

With Izuku’s mind completely erased by overstimulation, he’s running on nothing but the blonde’s instinct. The blonde can see him drifting, those green eyes glazing over, and he’s not about to let the nerd escape into unconsciousness just yet. He needs Izuku present for every second of this.

Katsuki closes the distance, snapping Izuku back to reality by grabbing his jaw and forcing his head up. He stares directly into the younger’s blown-out pupils, his own gaze fierce and predatory.

“Look at me, nerd. Don’t you dare close your eyes,” Katsuki commands, before crashing his mouth against the younger’s once more.

The kiss is sloppy and desperate. In the middle of the friction, Katsuki pulls back to see Izuku’s flushed, panting mouth hanging open in exhaustion. Without a word of warning, he spits directly into the smaller boy’s mouth. The string of saliva coats Izuku’s tongue before Katsuki immediately dives back in, swallowing it back as he resumes the deep, filthy kiss.

“Ah... hngh... K-Kacchan…” The nerd’s whimper is muffled against his lips. Tasting Katsuki’s spit makes his whole body jump, his toes curling as he tightens around the older’s cock even more. 

But Katsuki is a greedy bastard. While his lower body continues to deliver heavy, punishing thrusts, he pulls away again. He spits on his boyfriend’s chest, watching it trail down his stomach until it disappears into the wet friction of their joined hips. He uses the slickness of his own spit to lubricate his fingers, returning them to Izuku’s clit to resume a merciless, sliding grind.

The sounds filling the room grow wetter and filthier. With every messy exchange, their saliva mixes and strings between them, dripping down Izuku’s jaw as Katsuki continues to drown him in a relentless, breathless kiss.

For Izuku, every drop of Katsuki’s spit feels like a brand of ownership. Lost in a haze of sobbing breaths and tremors, he has no choice but to consume everything his Kacchan forces on him. 

Even as the aftershocks continue to rack his frame, the distance is suddenly unbearable. Izuku is still bent forward, his trembling arms gripping the headrest and his legs shaking so violently he’s nearly falling, but the physical space behind him feels a lot. 

With a broken, needy sound, he abandons his vulnerable stance. His knees almost give out as he tries to find his footing, his body swaying dangerously as he practically lunges backward, seeking the solid heat of Katsuki’s chest.

He reaches back blindly, his fingers fluttering through the air until they find the side of his boyfriend’s face. Despite the way he’s being jolted and wrecked, he doesn’t push away. Instead, he gently cups Katsuki’s cheek, his thumb grazing over his cheekbone, searching for tenderness. 

“K-Kacchan…” he whimpers, the name sounding like a soft plea amidst the wet, heavy sounds of their bodies colliding.

It’s a beautiful contrast. While Katsuki is pounding into him recklessly, Izuku is trying to nuzzle into the crook of his neck. Even as his body is jolts by every punishing shove, Izuku tries to nuzzle into the crook of his boyfriend’s neck, seeking the heat of his skin. He twists his head just enough to press a series of soft, dizzy kisses along Katsuki’s jawline. 

Each time Katsuki bottoms out, Izuku lets out a sweet, kittenish moan. His small hand drifts from the damp spikes of Katsuki’s hair, fumbling blindly until he finds his hand. When he finally catches Katsuki’s hand, Izuku interlaces their fingers, squeezing with a desperate strength even as his legs threaten to buckle beneath him. He pulls Katsuki’s hand upward, bringing those rough knuckles to his lips to kiss with a dazed, adoring smile.

“Love you... so much... ah!... Katsuki,” he whimpers. His voice sounds small and shaky while they continue their messy, heavy friction.

The moment Izuku captures his hand to kiss his knuckles, the air in the blonde’s lungs hitches. He puts a heavy arm around Izuku’s waist to haul him flush against his chest. He pins him there, skin-to-skin, until he can feel the frantic, erratic rhythm of his boyfriend’s heartbeat hammering against his own ribs.

“You’re such a... fucking brat, baby,” Katsuki rasps. The mean, sharp edge of his voice has bled away, replaced by a thick, desperate heat. He buries his face in the crook of Izuku’s neck, his teeth grazing the sensitive skin in a sharp nip before he licks the mark with a soothing tongue. “Distracting me... with this sappy shit…”

He inhales deeply, dragging in the scent of salt, sweat, and his Izuku. Driven by a new, frantic hunger, Katsuki’s thrusts lose their calculated rhythm, becoming deeper and more punishingly frequent. It’s no longer just about the friction; he’s chasing his high. 

“I’ve got you,” Katsuki chokes out, his voice uncharacteristically choked with emotion. “I fucking... I love you too, damn it. Always.”

“K-Kacchan... please!” Izuku wails, his head lolling back against Katsuki’s shoulder as his eyes roll into his head, his consciousness finally snapping under the weight of it all.

“I’m gonna—! Izuku!

Katsuki’s entire frame seizes, his muscles turning to stone as a guttural, animalistic groan rips from his throat. He delivers one final thrust, burying himself to the absolute hilt and locking them together. He stays there, pinned deep and trembling, as he cums in hot, rhythmic pulses that Izuku feels deep inside. 

“Izuku... nggh... fuck,” Katsuki chokes out, his voice a wrecked, breathy mess of a sound. He buries his face in the crook of Izuku’s neck, his breath hitching as he loses the battle for control. “You’re so tight... taking it all... fuck, you’re literally milking me dry.”

The sensation of being filled to the point of overflowing is the final trigger. Izuku’s core convulses in a violent, weeping clench, his walls seizing around Katsuki in a desperate, milking grip that forces a strangled, high-pitched moan out of the blonde.

“That’s it,” Katsuki gasps, his hips twitching involuntarily as he feels the frantic, rhythmic spray of Izuku’s own climax hitting the bedsheets. “Take every drop… Nggh, yeah... just like that, baby.”

Izuku’s vision turns into a blinding white spark, leaving him limp and shattered in Katsuki's arms as they both drown in the heavy, wet aftershocks.

The heavy silence that follows a storm finally settles over the room, broken only by the sound of their ragged, synchronized breathing. Katsuki doesn’t pull away immediately, he keeps Izuku pinned against his chest, his face still buried in the crook of the nerd’s neck as the last of the aftershocks fade into a dull, warm ache.

Once his strength returns, Katsuki moves quickly. He helps Izuku settle onto his shaky legs, though the nerd is so overstimulated he’s basically a puddle of soft sighs and drooping eyelids. He grabs a warm, damp towel, kneeling on the ruined mattress to carefully wipe away the evidence of their chaos. He is thorough, cleaning the slick from his boyfriend’s thighs and the cooling heat from his own skin with a focused silence.

He treks over to his cabinet, and dresses himself. Then, he pulls out a pair of his own oversized sweatpants and a soft black t-shirt. He dresses Izuku by lifting his arms, sliding the fabric over his head while the said boy just leans his forehead against Katsuki’s shoulder, humming contentedly.

“K-Kacchan... sleepy…” Izuku mumbles, his fingers weakly hooked into the hem of Katsuki’s shirt.

“I know, nerd. I’ve got you.”

The blonde scoops Izuku up bridal-style, ignoring the way his own muscles protest. He carries the smaller boy out of his room, past the hallway, and into the quiet sanctuary of Izuku’s bedroom. He tucks him into the fresh, clean sheets.

“K-Kacchan?” Izuku murmurs, his voice barely a thread. “Stay?”

“I’ll be back, Zu.” Katsuki whispers, pressing a lingering, firm kiss to Izuku’s forehead. “I have to clean up the mess we made in my room first.”

Back in his own room, the sight is a disaster. Katsuki works in a focused trance. He strips the bed, tossing the ruined linens into the hamper and spraying down the mattress. It is a chore, but there is no annoyance in his movements.

He didn’t bother re-making his own bed. He didn’t want to sleep there, anyway.

Minutes later, he slides into Izuku’s bed, and the younger immediately gravitates toward his heat, seeking him out like a moth to a flame. Katsuki pulls him close, letting Izuku’s face press against his chest. 

“You’re a magnet, I swear,” the blonde huffs, but his arms were already wrapping around Izuku, pulling him in so tight there wasn’t a breath of air between them.

“Mmm... my Kacchan,” Izuku sighs against his skin, finally drifting off into a deep, peaceful sleep.

Katsuki close his eyes, his chin resting atop Izuku’s messy green curls.

 

Next morning, the kitchen is thick with the scent of coffee and sizzling eggs. Katsuki stands at the stove, his posture unusually relaxed. Behind him, Izuku is a little more than a pair of bright eyes and a mess of curls, swallowed whole by one of Katsuki’s oversized black shirts. He clings to the blonde’s back like a permanent shadow, his chin hooked over a broad shoulder while his brain hums in a hazy, post-bliss fog.

The domestic bubble bursts the moment a familiar, heavy footstep enters the room.

“Morning,” Kirishima chirps, his voice sounding far too awake. “Man, you guys are up early. Figured you’d be… I don’t know, sleeping in for a few years.”

“We’re hungry,” Katsuki grunts, his voice steady as he flips an omelet.

“I bet.” Kirishima leans against the kitchen island, tapping a rhythm on his coffee mug. He didn't say anything for a long moment, just watched them with a look of mischief. “Hey, Bakubro? I think the sofa’s broken.”

Izuku’s heart stops, he tries to disappear behind his boyfriend’s broad frame.

“The spring in the middle?” Kirishima continues, taking a slow, thoughtful sip of his coffee. “It’s got this… loud squeak now, and the cushions are damp.”

“Kirishima,” Izuku breathed, his voice a tiny, dying thing.

“Look, you can hide what you’re doing in the dark,” Kirishima said, throwing a sharp, meaningful wink toward the tangle of green curls. “But the sounds? And the smell? There’s no masking that, man. Honestly, it’s hard to get any sleep when it sounds like someone is actively drowning in the middle of the common room.” 

Izuku’s face goes hot, the heat spreading all the way to the tips of his ears. “Y-You... you knew?”

“Midoriya, between the rhythmic, heavy slapping and those high, shaky little hitches you were making... It was intense. You sounded like you were gasping for air between splashes. I didn’t know a human body could even produce that much... noise, or that much fluid.”

Kirishima shifts his gaze to Katsuki, his expression a mix of impressed disbelief and mischief.

“Manly stamina, Bakubro. But seriously? Scrub the sofa. It looks like someone emptied a liter of water on the cushions. I’m surprised the floor isn’t flooded.”

Katsuki doesn’t flinch. He doesn’t even pause his steady flipping of the eggs. He just cuts a sharp smirk over his shoulder, his crimson eyes gleaming with zero remorse. 

“Yeah, he made a mess. Spent half the night twitching and spraying like a fountain. If the wet spots bother you that much, feel free to grab a front-row seat next time and help us clean up. All you have to do is ask.”

“Kacchan! Please stop talking!” Izuku shrieks, the sound cracking as his soul practically attempts to vacate his body.

Kirishima lets out a low, husky laugh, straightening up and clapping a hand onto the blonde’s shoulder. He turns his gaze toward Izuku, his eyes dark with a newfound sense of amusement. 

“Anyway, enjoy your breakfast. Drink some water, Midoriya. You look like you’ve lost a lot of fluids,  and maybe stay off your feet today. You’re walking like a newborn deer.”

With a low, casual whistle, Kirishima turns to leave. He lingers at the threshold for a heartbeat, glancing back at Katsuki with a daring, sharp glint in his eyes.

“Oh, and Kats? Careful with that invite. I’ve heard him gushing, but I’m more interested in seeing how he looks when he’s being wrung out so hard he can’t stop spraying. You keep talking about front-row seats and I might actually take one.”

He vanishes down the hall, leaving behind a suffocating silence. Izuku stays frozen, his forehead pressed against Katsuki’s shoulder blades, waiting for the ground to simply open up and end his misery.
