Work Text:
Shouto walks into the elevator, shifting his hold on the two reusable bags–one in each hand–with the groceries for the next week. He presses the button for his floor, and only a second after the elevator starts moving up.
In three days, Izuku is coming back home after being overseas for three whole months.
Shouto is used to the hero work, to being away from Izuku sometimes, but he still misses him everyday. Of course they text each other and video call often, but with the time difference it's difficult. Izuku was excited to go to the USA, but now even he started complaining about how it's hard to catch a moment to talk to each other during reasonable hours for both of them. Although Shouto doesn't mind losing sleep if he can hear Izuku's voice again.
Still, it’s not the same. Izuku isn’t there, nestled in his arms when they wake up in the morning, he isn’t in the shower singing some silly song that got stuck in his mind when he heard it playing in the radio during work hours, he isn’t there to cling to Shouto and melt into his arms after a particularly hard or upsetting day.
The apartment is unbearably quiet and cold, and it feels so wrong somehow, so empty without him. Without Izuku's scent, his inner alpha is on edge, unsatisfied with the world, and the only things keeping him in check are Izuku’s clothes that give Shouto peace of mind every time he smells them. Although after three months they lost most of the scent, making Shouto’s alpha side feel unsettled again.
But in just three days, everything will be right again.
Today is Saturday, and Shouto went out to get groceries for when his mate returns. He bought some meat, rice and vegetables, a strawberry tart for Izuku, and all the ingredients he’ll need to make katsudon.
He needs to prepare some food the day before Izuku comes back so that they’d be able to just heat it up quickly and eat it when they need it. The water they don’t need to worry about, there’s plenty at home. All because Izuku will be returning right before his heat starts, or at least that’s what they agreed on. The preparations aren’t anything new to Shouto, they’ve been through the heats and ruts together so many times that Shouto does everything almost as if on autopilot. Still, he can’t help but feel a bit more excited than usual, waiting for the day of Izuku’s arrival with impatience.
This time, they’re trying for a child.
Although a male omega technically can get pregnant outside of his heat, the chance is less than one percent. Still, they’ve never done it raw. Shouto always wore condoms, not wanting to risk it while both of them were busy being heroes. Izuku was hesitant about taking drugs repressing his heats–they were proven to cause some side effects that none of them liked–and birth control works better for betas, often failing during an omega’s heat, especially in case of male omegas whose fertility rate goes up even higher than female omegas' during this time. The likelihood of getting pregnant for a male omega is close to hundred percent then, and that’s why they decided to try when Izuku comes back.
After nearly twelve years together and eight years after they married, their lives became more stable, enough to be able to add another person into the picture. They both wanted kids, even if Shouto was shy about it at first, not sure if he’d be able to be a good father. Izuku would reassure him every time, and now Shouto just can’t wait until he gets to have this with Izuku. He feels a wave of happiness and anticipation spreading in his chest when he thinks about it. About their future, and what it will bring.
Shouto hears a loud ding as the elevator arrives at his floor. He walks out and heads into the hallway, reaching the door of his apartment. At some point, they moved to Tokyo, where the crime rate was the highest, and needed to stay in the heart of the city to be able to answer any emergency that might happen. They both prefer actual houses over apartments, but being heroes came first. Maybe now that they'll be having a pup they should think about buying a house. Or building one. They certainly have the money to do so. Their apartment is really nice and spacious, but there's something about houses that just feels different.
Shouto searches for his keys, finding them in one of his pockets. He fumbles with them for a moment, trying not to drop the bags, but when he's about to unlock the door, he realizes they've already been unlocked. Did he forget to lock them before leaving to the store? He's pretty sure he locked them, and if there's one thing about himself that he trusts, it's his memory.
Hesitantly, he grabs the handle and opens the door. Before he can even pass the threshold, a wave of powerful pheromones hits him right in the face, his body heating up, the burning sensation flowing straight to his groin.
The pleasant scent immediately envelops him, and there's also another aroma in the air, heavy and sweet, definitely belonging to slick. But what shocks him the most is that he can smell freshly baked lemon cake, jasmine flowers and a little bit of spiciness, something rather unusual for an omega's scent. Because it's definitely the scent of an omega. His omega. His mate. His Izuku.
He stumbles inside, the breath almost knocked out of him. The bags with the groceries land on the floor with a thud, and he takes his shoes off frantically, almost tripping over them as he heads inside. Extremely confused and embarrassingly aroused, he follows the scent that leads him straight to the bedroom.
The door is open, even if he closed it this morning. He holds his breath, heading in tentatively, and feels his skin itching at how powerful the pheromones are getting as he nears their source.
And right there, on their bed, lies Izuku.
The only piece of clothing he's wearing is the underwear–simple boxers–which he desperately tries to take off, but seems to be struggling. Shouto notices the rest of his outfit discarded on the floor in the most random places, and he guesses Izuku must have undressed on the bed and thrown them there.
He's huffing, a crease between his eyebrows expressing his annoyance as he tugs at the material of his boxers, but his hands shake so hard that he can't get them off himself.
It would be difficult to miss the obvious bulge between his legs, although the pheromones that he's letting out don't leave any doubts about what's happening.
Izuku is here, and he's in heat.
Shouto halts in the middle of the room, the realization sinking in. He tries to gather his thoughts, but his dick starts aching in his pants, already leaking, and it's all just because of the scent. It takes a lot of effort to clear his mind and not act on his instincts immediately.
What's he doing here? Shouto knows he was supposed to arrive in two days. Did something happen? An emergency? Did someone–Shouto feels rage building up in him at the sheer thought–drug him? Izuku might be the number one hero, but he's only human, and Shouto's mind supplies him with hundreds of possible explanations for this situation, one worse than another.
Izuku seems to have felt the change in the air, or maybe he just smelled his alpha's arousal, because his head turns in Shouto's direction suddenly. He stops fumbling with his underwear and relaxes into the mattress slightly, a relieved smile appearing on his face.
"My alpha," he sighs softly.
Shouto can feel his legs moving with a speed he didn't think he was able to reach. In seconds, the bed sinks slightly under the additional weight as he climbs onto it. He doesn't even think when he reaches out and grabs Izuku's knees, parting his legs and sitting between his thighs.
His omega is lying on the bed, squirming in discomfort. His expression is clearly hazy, cheeks flushed adorable pink. It takes him a second to focus, but he lets out the sweetest whimper when his eyes register the man above him.
"Shouto," he breathes out, a wobbly smile appearing on his face and a wave of pheromones of a content, relieved and very willing omega hits Shouto right in the gut. "You came."
No, he almost came.
Shouto feels his dick painfully throbbing in his suddenly way too tight jeans, and it takes all of his willpower to not finish right then, right there. It's all too much. He hasn't seen, hasn't smelled his mate for so long, and now his control is hanging from a very thin thread.
The fact that they're trying for pups isn't helping at all.
If anything, it only spurs Shouto on.
He can already imagine Izuku coming apart under him, chanting his name, cries of pleasure echoing in the room. His insides will wrap around Shouto's dick as if urging him to come, squeezing him so hard he can't pull out to make sure he finishes inside, his knot forming, and he'll fill Izuku with his release, with his pups. Not a drop of his come will go to waste. Izuku will take it all.
Shouto inhales sharply.
"Shit," he rasps, squeezing his eyes shut to regain some control over his body. The pheromones are all over the place, making Shouto dizzy with pure need, and it's so damn difficult to fight these urges when his omega is all flushed under him, wanting him. "Izuku," he adds almost breathlessly.
"Shouto," Izuku moans all over again.
At this point, Shouto has an almost death grip on Izuku's knees, and he's pretty sure Izuku doesn't feel the pain only because the heat is messing with his brain. He doesn't let go, though. He physically can't. It feels as if he'll lose last bits of sanity if he doesn't hold onto something like his life depends on it.
"Baby, listen to me, alright? Can you do that for me?" Shouto chokes out, forcing himself to open his eyes and look down at Izuku.
Wrong choice.
Izuku doesn't answer him. His eyes burn with need, shuddered breaths coming out of his parted lips, and he runs his tongue over his lower lip, staring up at Shouto with heated anticipation.
"Izuku, please," Shouto pants. "I need to make sure you still want—"
A strangled noise sounds in the back of his omega's throat, but instead of replying, Izuku brings his hand to the visible bulge in his boxers and starts rubbing it with a frustrated expression on his face.
One of Shouto's hands shoots out instantly, wrapping around Izuku's wrist and pulling his hand away from his own erection. Izuku tries to wriggle out of his iron grip, but Shouto doesn't budge.
"Izuku. Listen to me."
He really doesn't like using his alpha voice, but he knows that right now it's his only chance to get through to Izuku.
Finally, Izuku looks at him. There's a glint of recognition in his eyes as he stops squirming on the sheets. For a moment, he only stares at Shouto in silence, breathing heavily. Then, he gulps and licks his lips again, and it's clear that he's trying to keep himself in check even if he's visibly struggling. Shouto stares at Izuku's wet, red lips like he's in a trance, finding it hard to ignore how plump and soft they look. It takes him a second to recompose himself so that he doesn't instantly sink down and taste these lips.
Now, with his and Izuku's minds both somewhat present, Shouto needs to talk to him. He knows they already discussed it before Izuku's departure, but he needs to make sure that Izuku didn't change his mind.
"Before you left, you promised to come back before your heat starts and we agreed to try for a pup, remember?" Shouto breathes, and Izuku nods slowly. "Do you still want it? Just know that it's completely fine if you changed your mind. We'll just use condoms like we always did."
Shouto definitely wants to have a baby with Izuku, but it'll be him who will be carrying it and giving birth to it. It doesn't matter if he wants it if Izuku isn't on board with the idea. It’s something they both need to agree on.
Izuku lets out a quiet whimper. “Shouto,” he sighs. “No condoms. I haven’t changed my mind and I won’t.” He raises his free hand hesitantly, his fingertips ghosting over Shouto’s arm that is still holding Izuku’s wrist in place. Shouto shivers slightly at the touch. “I still want our pup, alright?”
Shouto gulps, his cock twitching in his pants painfully.
"I missed you," he whispers, finally letting go of Izuku's wrist and pressing a gentle kiss to his knee.
"Me..." Izuku tries to speak, but he gasps as his body produces another wave of slick, further ruining his already wet underwear. The sweet scent hits Shouto's nostrils with crushing force, making his brain short-circuiting for a brief moment, his grip on Izuku's knee tightening. Izuku's hands clench and unclench on the sheets repeatedly in quick motions.
"Me too," he pants desperately and ruts his hips up in search of friction. When he doesn't find it, he lets out a desperate whine that wakes Shouto up from his stunned state and has him remove Izuku's boxers in a flash. He throws them somewhere on the floor, too busy to care where they land.
Having his knee free of Shouto's hold, Izuku hooks his leg around Shouto's waist, trying to get him closer, and the alpha immediately complies, leaning in and kissing him hard. One of his forearms rests next to Izuku's head so that he could get close enough, while the cold fingers of his other hand thread into Izuku's hair, carding through the soft, silky locks that are already slightly damp with sweat.
Shouto slides his tongue between Izuku's lips, their teeth clicking, and Izuku immediately reciprocates. Shouto revels in Izuku's taste as their tongues swirl around each other, pressing and rolling, and he sucks Izuku's bottom lip into his mouth, getting another whimper out of him. Shouto feels his skin becoming incredibly hot as Izuku moans into his mouth and rolls his hips up once again, this time getting the friction he so desperately needs. Shouto feels a shiver down his spine that almost leaves him breathless, and he presses against Izuku harder, their chests colliding, and Shouto's body starts to itch with all the clothes he's wearing.
He moves away from Izuku to quickly discard his shirt, unzip and shove his pants along with his boxers down, freeing his aching dick. He shivers as the hot air around them hits his naked skin. He doesn't have the time to take the pants and the underwear off fully, only managing to get them down to his knees, because Izuku reaches out for him, grabbing his arms and sinking his nails into his skin with a force that Shouto just can't brush off.
"Shouto, please," Izuku chokes out, tears welling up in his eyes as he grinds into Shouto's hips again, pressing their cocks together. Shouto inhales sharply, squeezing his eyes shut for a second. "I need it," Izuku continues, nearly sobbing.
"Shh. It's okay, baby," he whispers gently and descends on Izuku again, hands cupping his omega's soft cheeks. His thumbs brush along Izuku's freckles, now even more visible on his flushed face. "I'll take care of you."
Izuku takes advantage of Shouto leaning down and wraps his arms around his neck tightly, one of his hands grabbing the back of Shouto's head. Shouto shoves their hips together, and a low grunt sounds in the back of his throat at the feel of it, his legs going numb for a second. Izuku lets out a choked gasp and pulls at Shouto's hair desperately, and Shouto groans, wondering if Izuku knows how much he's affecting him.
Shouto bites his lower lip harshly, trying to stop the building pleasure in the pit of his stomach. He can't come now, not until he's buried deep in Izuku, his knot locking them together.
Their hard cocks press against each other, Shouto's already heavily dripping with precum, and he can feel Izuku shuddering under him, eyes half lidded as a long moan escapes his lips.
A wave of raw affection and yearning tugs at Shouto's heart, making him melt at the sight of his mate's blissful expression, his dick twitching achingly against Izuku's.
In Shouto's eyes, Izuku has always been beautiful, but there's something special about the way he trusts Shouto with his whole being, exposing everything for Shouto to see. There's something special about how he allows himself to lose control and fall apart only in front of Shouto.
No matter how much Shouto wants to take his time, to carefully make Izuku come undone, caress and once again explore every part of his body, he knows he can't do that now. His omega is under him, begging for relief which only Shouto can give him, and after three months of not having his mate next to him he knows his patience is running out.
It's alright, though. Izuku doesn't want him to be patient, not when he clings onto Shouto like that's the only thing he knows, not when his flushed body presses against Shouto's so closely that he can hear his racing heartbeat through the touch.
The corners of Shouto's mouth turn slightly upwards, fingers running through the green locks, and then he's in motion, his lips meeting Izuku's soft ones in another kiss. This time it's gentle, slow, it's a kiss full of warmth and love that Shouto wants to give him. It's a promise, a promise of comfort and safety and forever. It's a secret, something to be kept only between the two of them, something seemingly fragile, but unbreakable at the same time. It's the least he can do before his brain completely gives in to the burning desire prickling at his skin.
Shouto moves away from the kiss, their foreheads connected, their faces so close that Shouto can feel Izuku's hot breath on his lips. Izuku stares at him entranced, stares like you'd gaze at the night sky filled with bright stars, in the middle of a flower field on a warm summer night.
Shouto chokes up, his gut burning, and he grabs Izuku's arms, forcefully removing them from his neck to be able to lift his upper body up. A pitiful whine tears through Izuku's throat when he's suddenly denied the proximity, but it changes into a cry of pleasure when Shouto wraps his hand around Izuku's cock and gives it a quick stroke, rubbing the head with his thumb.
And just like that, Izuku comes, sperm splattering all over his chest and Shouto's hand.
"Shouto," he breathes "Please, hurry up. I need you inside me," he pleads.
Shouto feels a shiver down his spine, his mind filled with desire to just bend Izuku over and shove his cock in his ass, slamming him into the mattress until he melts under Shouto from the pleasure.
Izuku reaches out to clench his fingers around Shouto's wrist, Shouto's hand still wrapped around Izuku's dick. Not long after he comes Izuku manages to become hard again. That's not uncommon for an omega in heat, but he always finds himself slightly surprised when it happens.
"Whatever you want, Izuku," he whispers, taking his hand off Izuku's cock as the omega's eyelids flutter in anticipation.
Shouto grabs Izuku's thighs, his fingertips digging into the soft flesh as he yanks Izuku up, his ass now mere centimeters away from Shouto's face. Izuku lets out a surprised yelp, bracing himself with his arms, his hands clenching on the crumpled sheets.
Shouto leans in slightly, his lips ghosting over the entrance, and he breathes a huff of hot air into the tight heat, his mind dizzy with the sweet scent of Izuku's slick.
"Shou—" Izuku's words change into an incoherent whine as Shouto's tongue dips into his hole suddenly.
Shouto loves Izuku's taste. It's not artificially sweet like it's often said to be the case with omegas–it has some kind of freshness to it, like a lemonade on a hot day, or a cup of warm tea on a winter night.
Shouto lets Izuku's lower body lean against him as his hands grab Izuku's butt cheeks and yank them apart, and he's thrusting his tongue further into Izuku.
Izuku's legs wrap around Shouto's head instantly, twitching every time he slides his tongue into his heat. His omega clings to him desperately, slowly becoming lost in pleasure, and Shouto couldn't be more pleased knowing he's the cause.
Shouto's left hand lets go of Izuku's cheek, slowly making its way to the middle, fingertips brushing along the heated skin. He lifts his head slightly and uses two of his fingers to further stretch Izuku's opening, feeling him clenching and unclenching around them.
"Please," Izuku breathes out shakily. "Don't stop, Shouto."
"As you wish, baby," Shouto replies, his voice filled with need, but also with heavy affection, and he continues to thrust his fingers in and out, making Izuku let out quiet moans and gasps, chanting Shouto and please over and over again.
Soon, Shouto will make him scream his name.
He hears Izuku panting heavily as the omega tries to squeeze his thighs together, forcefully shoving Shouto's head down, closer to his entrance. Even more slick gushes out of it, making Shouto's mouth water.
Still not having enough of Izuku's sweet taste, he laps at the entrance before shoving his tongue into his hole, fingers still pressing deep inside Izuku. Shouto's cold hand squeezes Izuku's ass, his nails digging harshly into the soft flesh, and he shivers at the broken moan Izuku gives him in return as he comes for the second time.
Come shoots out of Izuku's dick, landing on the sheets and Izuku's upper body, including his face. Shouto pulls out his tongue slowly, deciding to leave his fingers inside for now, and takes in the sight before him.
Completely out of breath, Izuku's eyes are closed, his mouth open, trying to suck in the needed air. His whole body is flushed in pink and red, and his chest is a mess, a mixture of his two orgasms splashed all across his toned muscles. His throat, jaw, cheeks, lips, even some strands of his hair… It's all marked with the whitish fluid. Shouto feels a pang of arousal exploding in the lower part of his stomach, blood rushing straight to his already painfully hard cock. This will be the end of him.
"You look so pretty like this," he rasps, suddenly adding a third finger, thrusting in and out with quick motions.
Izuku's back arches, a loud whine sounding in the room, and Shouto can see his cock standing up again.
"Shouto, I'm ready, really, please," Izuku pleads, hands above his hand, grasping at the sheets desperately as Shouto's fingers work him open. "I need your knot."
His voice sounds almost pained, rushed, and it's shaking with every word falling from his lips. He's asking so politely, Shouto can't possibly refuse him, can he?
He takes out his fingers, completely soaked in slick, and pushes Izuku slightly forward so he's lying flat on the bed again. He looks down at his throbbing dick and wraps his hot, wet hand around it, spreading Izuku's slick across his length. He sucks in a breath and bites back a moan when their pheromones filled with arousal mingle in the air, both of them knowing what will come next. Izuku watches him with his eyes half open, chest rising and falling with every shallow breath escaping through his lips. It's like he's not fully there, mind too clouded with need.
Shouto's attention returns to his cock again, but he doesn't stroke himself for long. He doesn't want to come yet and he can already feel he's close.
"Alpha," Izuku says quietly between his shuddered breaths. "Make a mess out of me."
Shouto's head snaps up, a rush of excitement going down his spine and straight into his gut, and his vision goes blurry for a second, the world fading away as his instincts take over.
"Omega," Shouto rasps, barely a whisper.
Izuku lifts himself up, his legs shaking uncontrollably as he tries to get on his knees and present, and a small part of Shouto likes it, his alpha instincts making him excited about the show. But the larger part of him is having none of it.
"No," he growls, a frown appearing on his face, and before he can think more of it, he grabs Izuku's arm, throwing him onto his back again, his body thumping into the mattress. When he realizes what he's done, he loosens his grip instantly, breathing hard as takes in Izuku's startled expression.
"I'm sorry." Tentatively, Shouto lets go of Izuku's arm and leans down slightly, his other hand cupping Izuku's cheek as he caresses his skin, unintentionally smearing some of the come from earlier across his freckles.
"We're having a pup, remember? I want to see your face when I fill you up."
Izuku's face flushes crimson at that, his pheromones thickening to the point that Shouto's mind goes into frenzy, the need to mate and breed and take impossible to hold back now.
Shouto backs away slightly, lifting his right hand, the cold contrasting with Izuku's hot skin as he wraps his fingers around the behind of Izuku's knee, heaving him up to get better access. Izuku certainly isn't light, but adrenaline runs through Shouto's veins, making it extremely easy to manhandle Izuku the way Shouto wants.
He grips Izuku's leg tighter and lines himself up before pressing the head of his dick into the entrance. He sucks in a breath sharply, holding himself back from thrusting all the way in one go, his hand clenching around the behind Izuku's knee so hard that his fingers turn pale.
Izuku writhes under him, heavy breaths filling the space between them. His hips buck up to take Shouto in deeper, but Shouto holds him firmly in place, moving only a bit further, even if everything in him screams to go faster, harder, deeper.
"Shouto," Izuku whines loudly, urging him to force himself in, but even with his senses clouded by arousal, Shouto doesn't want to risk hurting his mate. Shouto goes in halfway without meeting much pressure, and only then does he decide to thrust into Izuku suddenly, burying himself in him to the hilt and letting out a low groan at the incredible tightness pressing at him.
He can feel Izuku's legs go limp, his body spasming before he comes just from having Shouto's cock fully inside.
Omegas can ejaculate many times during their heat, and Shouto remembers that–even if his mind is becoming fuzzy–but it's the first time Izuku came three times during one session, heat or not. And he's still hard.
"You're enjoying this more than usual," Shouto purrs, his dick pulsing achingly with the need for more friction.
Izuku's ears seem to burn in embarrassment as he acknowledges his words, and he covers his eyes with his arm, trying to take deep breaths as if to calm himself down.
"I'm sorry, alpha" he pants, his mind already too occupied with his heat to think straight anymore. "I don't know why, but I can't help it, I'll try to—"
"It's okay, baby," Shouto interrupts Izuku's frantic rambling, reaching out to grab his wrist and remove his arm from his face. "You're perfect. You're doing so good. Don't worry and let me take care of you."
Izuku shudders visibly at these words, his hands clutching at the sheets. "Alpha," he chokes out, staring at him with half lidded eyes. "Shouto."
Shouto slides out almost fully, just to slam back harshly almost immediately after, setting up a relentless pace as he thrusts into Izuku.
Izuku cries out loudly, Shouto's name on his lips, and the sound rings in Shouto's ears, spurring him on to pound into him even harder. The bed creaks under their weight, shakes with the force Shouto's hips sink into Izuku's as he presses him into the mattress over and over again. Shouto couldn't care less about the bed, though, he's too far gone for that. It can break for all he cares, right now he can only think about the pleasure building up in his gut and his omega.
Izuku is his. His sweet, beautiful omega.
"Fuck, you're so tight," Shouto groans, snapping his hips, slamming into Izuku, his left hand rising to grip Izuku's thigh. Shouto didn't even realize both of his sides started to act up earlier, increasing and decreasing his temperature, but Izuku seems to like it, seeing as his body twitched at the touch, his mouth open in a silent gasp.
"You're taking me so well," Shouto rasps, and Izuku shudders under him, his eyes unfocused, hands gripping the sheets like they're the only thing keeping him from falling apart.
"Please…" Izuku gasps, but at this point none of them are sure what exactly he's begging for, only incoherent pleas, heavy breaths and loud moans leaving his lips.
Shouto loves the way Izuku's walls clench around him as if they're trying to suck him in, not wanting to part.
The scent of Izuku's arousal mingling with his own, his sweet slick, their sweat, everything makes Shouto dizzy and hot all over, even his right side seems to burn, the cold pricking at his skin. He buries himself in Izuku again and again, and he can already feel his knot start to form at the base of his cock. Izuku, feeling his insides being spread even further, gives a particularly long moan and bucks up his hips instinctively.
Shouto hisses, his thrusts becoming frantic as he loses the rhythm, and he digs his heated fingers into Izuku's flesh, shifting him slightly so he can hold him close to him firmly.
Izuku cries out as Shouto hits the sensitive bundle of nerves inside him, his lips parted, eyelids fluttering in pleasure.
Shouto reaches his right hand forward, his cold fingers wrapping around Izuku's dick, still wet with his slick and come, and he starts pumping him, thrusting his hand up and down in an uncontrolled manner. The omega trembles at the difference in temperature.
"I'm close— Alpha—" Izuku pants, most of his words incoherent, interrupted by moans that tear through his throat simultaneously.
"M-Me too," Shouto stammers, his whole body shaking with the force he puts into the thrusts, and he acts purely on instinct, reason already too far gone to lead him. "You feel so good."
"Don't stop," Izuku chokes out, his insides closing on Shouto's dick as his knot grows, filling him even more, and he snaps his hips in a frantic manner, trying to meet Shouto's. "Don't stop, Shouto."
"Fuck, I'm—" Shouto curses breathlessly, pounding into Izuku until he can feel his knot expanding, locking him inside.
Izuku's body spasms as he comes, his whole body going limp under Shouto, moans stuck in his throat as he parts his lips in a silent cry.
And then Shouto is coming too, orgasm tearing through his body with a sudden force, a low moan shaking its way out him. He fills Izuku with his release, his vision becoming white for a moment, and he's not able to stop the violent spurts that just keep shooting his sperm deep inside Izuku. The omega sucks in everything greedily as if trying to milk him dry, a blissful smile on his face, his hand splayed over his abdomen as if he’s trying to feel Shouto from underneath, and it sends another rush of excitement through Shouto’s veins.
Heavy pants sound inside the room, and after a longer moment Shouto finishes fully, not being able to produce even a drop more, even if Izuku's walls keep clenching on him. Shouto's mind clears slightly, and he shifts their bodies so that he's laying flat on the bed with Izuku's limp body sprawled on top of him, his head resting on Shouto's chest. He lifts his left hand and puts it on the small of Izuku's back, drawing small circles on the soft skin with his thumb.
For a while, there's only silence as both of them try to even out their breathing.
"I thought I'd never stop coming," Shouto murmurs suddenly, his voice hoarse. "I've never come this hard before."
Izuku snorts at that, the sound still shuddered, but at least he seems to have come back to his senses.
"I came four times," he points out with a sigh. "Four."
Shouto stills, his thumb stopping the soft strokes, and he blinks slowly when he takes the information in.
"Oh," he breathes out. "You're right."
"I loved it." Izuku turns slightly, letting out a quiet groan when he feels Shouto's knot shifting inside his sensitive hole, and he presses his lips to Shouto's stomach in a light kiss. "I guess it just shows how much we want this pup," he laughs.
Shouto's unscarred cheek flushes pink, a tingly, warm feeling spreading around his heart. "Yeah," he manages to say, ears burning, and he resumes caressing Izuku's skin with his thumb.
Izuku lays his head on Shouto again, his plump cheek snuggling against his toned muscles, rubbing at the skin softly. Izuku sighs, the breath tickling at Shouto's stomach. "Sorry, I got it all over you."
Shouto needs a moment to realize what he means, and then he feels it–the come on Izuku's upper body now also sticking to where their bodies press against each other, the sheets that are in a dire need of washing, and his pants and underwear that feel so itchy around his sore legs… Still, he couldn't care less. The air is filled with a happy omega's scent and he can't even bring himself to be uncomfortable with the mess they've made when he feels so satisfied, knowing he took good care of his mate.
"...'s okay," Shouto mumbles, raising his other hand to bury it in Izuku's hair. "You were perfect."
He can feel Izuku's cheek warming up at the compliment, and a smile tugs at his lips at the reaction, sparks colliding in his chest, making him feel warm all over in the most tender way.
“But why did you come back so soon? Weren’t you supposed to arrive on Tuesday?” Shouto asks, remembering his shock when he smelt Izuku as soon as he opened the door.
"Oh, it’s..." Izuku replies somewhat bashfully. “It’s because I was thinking so much about you and the baby, and s-somehow, uh…” He stammers. “It just started earlier than it should have. So I had to hurry back home. Sorry, I barely managed to get here without losing my mind, otherwise I’d have at least texted you.”
He’s clearly embarrassed, but Shouto is only able to see it as endearing.
"Don’t apologize," Shouto hums contentedly, leaning slightly forward to press a soft kiss to Izuku's head before he flops on the bed again. “I’m glad you’re here now. It was lonely without you.”
Izuku is quiet for a longer moment before he presses his cheek harder to Shouto's skin. "I love you," he whispers, his voice heavy with affection. He raises his head slightly to meet Shouto's eyes, the corners of his mouth turned up in an adorable smile.
Raw emotion tugs at Shouto's heart, and he feels choked up for some reason, losing words for a second.
"I love you too, Izuku," he breathes, his gaze expressing more than he'd ever be able to put into words. "So much."
Izuku's smile widens. "I know."
And Shouto melts, just like that.
