Work Text:
Aizawa Shota is having the worst week of his life. His desk at UA’s teacher's lounge is completely covered in paperwork – be it assignments waiting to be graded or the couple unfinished reports from side missions he’d regretfully agreed on taking that must be completed as soon as possible or he’ll never get the Hero Public Safety Commision out of his ass.
And yet, none of that compares to the deep, borderline painful jab at the back of his mind indicating that his rut is approaching much sooner than he and his mate had anticipated, most likely triggered by the huge amounts of stress and their lack of, ahem, activities, courtesy of their busy schedules.
All this built up tension did nothing to help the heavy sandalwood scent escaping Shota’s suppressors’ effects, or Hizashi’s unconscious purring meant to calm his mate down from the other side of the room.
Being work partners, both Shota and Hizashi have become pretty good at keeping things professional between them during work hours, only occasionally indulging in quick fucks when everyone else has left the building and the risk of getting caught is minimal – an excitement he’ll never admit out loud to missing greatly.
It doesn’t mean the others are completely unaware of them, or that they’ve never been caught in the past, but no one has actually dared to actively put a stop to them. Principal Nedzu did try, once. Having known both men since they were young teens and having witnessed their bond grow stronger and stronger throughout the years he thought he could approach the matter in a sort of nostalgic way, but a single glare from the blond and a loud growl from Shota was enough to put the beta in his place.
Another wave of pain.
His alpha impulses take over him for a second, and he is unable to stop himself from shooting a hungry glance at his mate, who’s currently busy typing away on his computer. Sitting on the desk behind him, Midnight meets Shota’s eyes and smirks knowingly, playing with the handcuffs around her wrists. The dark haired man rolls his eyes and looks back down at his desk. He shifts uncomfortably in his seat and uses all the willpower left in him to begin sorting through the mountains of organized paperwork.
Next to him, All Might works on his own paperwork. It’s almost comical seeing the tall, lanky man hunched over the small desk, desperately trying to figure out how to work his computer. The man notices his exchange with Midnight and carefully turns to him.
“Aizawa-san, maybe you should take a break…” All Might says, his alpha unfaced when Shota bares his teeth at him. “I can grade some of the student’s works, if you’d like.”
Damn his stupid heroic impulses. Shota takes a deep breath, calming himself down before answering.
“Thank you, All Might.”
Sometime later in the afternoon Shota looks down at his phone, sighing when he realizes it’s time for him to leave. He’d agreed on assisting the local police in a raid after getting involved with the capture of a villain group, still struggling with a few stragglers.
Hopefully, today it’ll be his last mission in a long, long time.
He wraps his capture weapon around his neck, adjusts his utility belt, and mumbles his goodbyes to the busy teacher’s room. He takes a moment to shoot a glance at his mate, who returns a kind smile that appeaces his heart, and leaves.
~~~
The moon sits high in the sky by the time he gets home. A single glance to the kitchen’s wall clock lets him know it’s only six minutes past midnight. He kicks his work boots off and takes a moment to roll his shoulders, alleviating some of the built up tension between his shoulder blades. His back aches with what he’s sure to be bruising, and the faint ache of his rut makes itself present again.
The small apartment he shares with his mate just a few minutes away from U.A. grounds is dark, lit by faint moonlight and general city lights gently seeping through the open windows. The alpha threads through the place with ease, used to navigating in the dark as an underground hero. Instead of using his sight he relies on his other senses, highlighting the feeling of soft carpet under his socketed feet and the intense mixed scent of sandalwood and caramel that covers every surface.
As he gets closer to his and Hizashi's shared bedroom he begins to hear the soft breathing of his mate, clearly in a deep, well-deserved sleep.
Another wave of rut claws at the back of his mind.
Shota very rarely gets a good night's sleep, hence why he’s always seen carrying his favorite yellow sleeping bag around whenever he’s not in active hero mode. For a person like him it’s much easier to catch a blink of sleep whenever he can instead of one continuous nighttime spell. The sight of his sleeping mate – long blond hair melting into the silky dark pillows, naked chest rising and falling gently in tempo with his breathing, long toned legs spread deliciously under the thin covers – was something he was used to seeing, yet never grew tired of witnessing and over time it became one of his favorite sights to get off to.
A low growl punches its way out of his throat.
He’s on fire. His skin itches and burns and his brain screams at him to take take take . The mental image of his sleeping mate being spread nicely on his cock is the last straw, and his rut hits him full force.
In a feverish daze he tears through his hero costume, clawed hands ripping the thick, black fabric apart with ease. In a single, powerful leap he jumps into their shared bed and reaches down to tear through his mate’s own clothing. Not for the first time, what’s little left of Shota’s consciousness is surprised to see his mate still asleep, shivering gently as his body is exposed to the cold air of the room.
He places himself between the blond man’s legs, spreading them to indulge in the sight of his mate’s most intimate parts. A ray of pale moonlight lights the spot, glistening between flaps of skin where a sweet slick has started to leak out as soon as the sleeping omega caught the scent of his alpha’s unleashed rut. Shota’s eyes take in the sight of his cunt for a few seconds before indulging in the rest of his omega’s body – the way his tiny cocklet lies soft and pink between sharp hip bones, his soft stomach, the dips in the skin where muscle mass gathers, small, plush tits and swollen nipples ready to be sucked on. Hizashi’s neck is slightly tense where it holds his head to the side, comfortably resting on his pillow. His full lips are parted slightly, and a line of drool runs down the side of his mouth into the silky pillowcase.
Shota’s cock twitches. A bead of milky precum gathers in his slit.
With a heartfelt “ Fuck,” Shota dismisses what foreign thoughts are left in his mind in favor of leaning in and burying his face between his mate’s legs. He takes his time allowing himself to take in each smell, each taste. He sticks his tongue out of his warm mouth, his breath hitting the delicate skin of his mate making him shiver once more.
A sweet, quiet moan leaves the blond.
With clawed hands, Shota spreads his mate’s cheeks enough for him to swipe his tongue between them once, twice – every small movement prompting slightly louder moans from his still sleeping mate. The taste of sweet slick clouds the alpha’s senses, eliciting a deep, continuous growl to rumble from his throat to the very tip of his tongue.
Hizashi’s hole twitches, gradually opening itself to welcome his mate.
More and more slick leaks out, mixing with saliva and dripping down Shota’s chin to pool onto their bedsheets. His tongue stops teasing and shoves itself as deep inside his mate as he can. He throws Hizashi’s legs over his shoulders, one hand still clawing at a soft muscled thigh while the other reaches over to play with his mate’s neglected cocklet. The omega is already hard, small drops of milky precum already leaking freely down the small shaft.
He rams his tongue inside, lapping at the clenching walls of his mate’s cunt, pulling back to slurp at the rivers of slick that pour out, then nipping and nibbling on the sweet, wet folds of flesh before diving back inside. Hizashi’s cocklet twitches in time with his whimpers and precum starts flowing much more freely from his slit to pool between Shota’s fingers. An excited growl leaves the alpha, thick fingers massaging the milky precum on soft skin, craving Hizashi’s sweet cum.
See, Shota’s mate is special . Male omegas possess cocklets, so small they’re almost useless to fuck yet they still have the ability to occacionally shoot cum – though not in the same quantity as a strong alpha can – and as rare as male omegas are, only a small fraction are considered ‘squirters’. Squirters are capable of shooting cum multiple times during mating sessions, explained to be an ancient reflex leftover from the separation of secondary genders. To Shota’s delight, his mate is one of these special omegas. He enjoys watching his mate cover himself with his own cum, screaming and twitching in time with his cocklet over and over again.
With every rut and heat, they challenge themselves on the amount of times Shota can make Hizashi squirt on his knot and tonight won’t be the exception.
The alpha buries his face deeper between his mate’s cheeks, pulling back only to run his tongue up the blond’s taint towards his adorable, tiny balls. He sucks one of them inside his warm mouth while his hand works a punishing pace on his shaft, stopping only to slurp the beads of precum leaking from his slit and jumping back to suckle on the small, rejected juicy testicle. Impossibly enough, Hizashi remains asleep throughout his torment.
Shota’s hips rut against their shared bed, his cock twitching and leaking precum on the sheets with abandon. When his need finally becomes unbearable and the painful anticipation is no longer enjoyable, he props himself up on his knees. He wipes the mess of saliva and slick from his mouth with his forearm and grips onto his mate’s legs still spread over his shoulders. His fat, heavy cock bobs with every shift of his body, and finally comes to a rest on his mate’s taint. He grinds teasingly between the blond’s cheeks, passing over the twitching furl of his hole over to the soft skin of his balls and sopping wet cocklet.
With practiced skill he lifts the omega’s hips to his level and places the head of his cock right at the opening, barely kissing the pink rosebud-shaped entrance, and looks up at his mate’s face.
“‘zashi,” he grunts out, hips pressing slightly forward. He shivers at the feeling of his mate’s wet hole giving in, welcoming him in so, so easily, desperately fighting the urge to thrust inside. “Kitten, wake up.”
The demanding tone penetrates the deepest corners of the omega’s brain, and his eyes flutter open revealing beautiful green irises. Shota waits until their eyes meet, until confusion begins to show over sleep-clouded eyes, really savoring the way his mate lies clueless under him, already begging so prettily even though he has no idea what’s happening between his legs, and in one swift thrust he shoves his cock inside.
Hizashi’s eyes widen, back arching in a deep gasp letting only his shoulders and his arms make contact with the bed. He feels himself opening wide, sucking in greedily at his mate’s cock, perfectly shaping itself around the familiar intrusion. Almost immediately, Shota pulls out harshly, leaving just the tip inside. The omega’s hole desperately contracts around it, sucking on the leaking mushroom head and begging for his alpha to fill him up again and again.
Begging for his alpha to knot him.
After a couple teasing thrusts Shota sets a punishing pace, filling the room with the sounds of his heavy balls slapping against his mate’s dripping cunt. Animalistic growls and whimpers echo inside the four soundproof walls of their bedroom, Hizashi’s omega instinct to suppress his own quirk doing nothing to quieten the sounds leaving his drooling mouth.
None of them is conscious of the time, but it can’t be more than five minutes since Shota woke him up and began splitting him in half with his cock when the omega begins to feel the extra stretch of his mate’s knot forcing its way inside.
“‘ gonna knot you so good,” Shota mumbles under his breath, voice rough and deep hitting Hizashi in all the right places. “So, so good. Fuck.”
His knot grows bigger and bigger at the base of his cock, pulling on the dripping flaps of swollen red flesh of Hizashi’s hole and forcing them to open up just for him. Hizashi can’t say or do anything, still battling the shock of being woken up in such a way. It’s been so long since he’s been woken up by his mate shoving his dripping cock deep inside him like this, the omega’s body so relaxed and compliant under his alpha’s strong hold, he almost forgot how fucking good it makes him feel.
The thought alone is enough to tighten his hold on his mate’s cock, milking it for all it’s worth. Shota howls, throwing his head back and squeezing Hizashi’s hips in a bruising grip as his knot is fully sucked inside the tight heat and his balls draw in to shoot a long stream of hot cum into his mate’s womb. Hizashi’s own cocklet twitches once, twice, and a spurt of watery cum shoots it’s way out, covering his abs.
Still grinding his knot inside his mate’s tight heat, Shota leans down to clean up his mate’s mess.
“ Fuck, Shota,” Hizashi breathes out once his breathing calms down. His mate looks up at him with a dangerous smirk and grinds the thick mushroom head of his cock over the abused bundle of nerves deep inside the blond, triggering another long, suffering moan. “Y- your rut…”
“I’m not done with you,” The dark haired man growls out, pulling his hips back to feel Hizashi’s hole squeeze even tighter around his knot.
The blond sucks in a deep breath, whimpering when his insides fight to keep the thick knot inside, stretching and squeezing around the swollen flesh in desperate spams. His long legs flail by Shota’s sides, their own strength rivaling his alpha’s own causing him to press his hips back against the blond’s throbbing cunt.
Trailing a naughty hand back towards his mate’s cocklet, Shota leans in. His puffing breaths tickle the side of Hizashi’s face and the omega knows to bare his neck for his mate to bite.
“Good boy,” the alpha purrs out, niping gently at the skin before sinking in his teeth. Hizashi sighs, running long, deft fingers through soft locks of hair. “Such a good little omega, just for me.”
The fingers around his spent cocklet tighten their grip, the thumb’s rough pad playing with the dripping slit. Hizashi whimpers again. He curls his long, saking fingers around Shota’s dark locks in what he means as some form of warning but ultimately turns Shota on even more. The alpha smirks, pulling back slightly to meet his mate’s eyes once more, and sinks a fingernail into the slit, forcing it to open slightly. Hizashi cries out, pulling harder on the man’s dark locks.
Shota’s eyes flicker to their bedside table where their favorite toys sit, including a full set of sounds. He looks back at Hizashi, then down at his angry red cocklet, and decides against it. He doesn’t want anything that isn’t him touching his omega tonight. Instead, he digs his sharp nail in deeper, watching the clear remnants of cum and precum run down the swollen head to the short shaft, down his balls to meet the slick gathered at his taint. Hizashi squirms, kicking his legs awkwardly while keeping himself open for his alpha.
Shota leans back down to playfully nip at his omega’s neck, running his tongue over the reddened, bleeding skin and trailing down to his chest where a pair of pink nipples await. He blows gentle, warm air over the expecting nubs, watching them stand at attention. With an approving growl, he wraps his mouth around the left. The soft, pillowy flesh of his tit hugged Shota’s face, rising and falling with every stuttered breath.
He sucks and laps on his mate’s tits until his knot gives slightly, allowing him to pull out. His half hard cock slips out of the sopping wet hole with a squelch, and a trail of thick cum and slick connects the head to the angry red flaps of skin. Hizashi winces at the feeling. His head is clouded in his mate’s rut, instinct relaxing and molding his body to comply with Shota’s needs. Soft, periodic twitches keep shaking his body with overstimulation, but when his mate pulls back to look into his green eyes, he can’t help but unconsciously spread himself on the bed even more, presenting his overworked body.
Shota lets go of his legs, letting him fall gracefully on the mattress. He spreads his own legs by his mate’s sides and crawls his way up to sit on the omega’s reddened chest. His heavy, wet cock sits itself on the dip between his tits, swollen mushroom tip nudging at the omega’s chin. As if on queue, Hizashi parts his lips and rolls his tongue out invitingly. He meets Shota’s brown eyes and flutters his long eyelashing while delivering tiny kitten licks at the tip. The strong taste of his mate’s cum mixed with his own cunt juices sparks an animalistic need in him.
The blond cranes his neck, pulling on the pillow behind him to elevate his head at just the right angle before wrapping a hand around his mate’s shaft and eagerly guides the swollen cock to his waiting mouth.
Shota shifts a little more, careful not to put too much weight on his mate, and sinks a scarred hand in the mess of golden locks beneath him. He sinks his cock inside, shoving his thumb alongside it to help prop open his mate’s jaw. The blond’s throat spasms in protest to the sudden stretch for a few seconds before the hormones kick in, relaxing every muscle in his face and throat. Warm, fat tears pour out of the corners of his sides onto the pillow under him, swollen red lips wrapping themselves tighter and tighter around his alpha’s shaft while his tongue flickers desperately in an attempt to work the sensitive skin of the underside and his hand pumps what is left unable to fit inside his mouth.
Shota rewards him by thrusting even deeper, ignoring the choking and trashing from under him. Instead, he chooses to reward his omega by pulling on his long blond locks the way he knows his omega gets off to. Hizashi’s shivers become more violent, almost kicking the alpha off his chest. His purring grows louder, and the vibrations hit the alpha so fucking good .
Thrust, thrust, thrust, thrust…
With a loud groan his knot gives, releasing bucket loads of thick, sweet cum deep down his omega’s throat. Hizashi struggles to swallow, the contractions of his throat milking more and more cum from the alpha.
Once he’s done cumming, Shota hesitantly pulls back. A thick line of drool and cum connects them as Hizashi fights to regain his breath. Patiently, Shota rubs the thick head of his swollen red cock over the omega’s abused lips, rubbing milky white fluids all over that pretty mouth.
Panting and teary eyed, the blonde pokes out his tongue, showing remnants of his alpha’s load covering the insides of his warm mouth before swallowing them, showing his alpha the empty space left. Shota grins.
“Good boy,” the alpha purrs, reaching up to pet his lover’s face.
Hizashi’s chest rises and falls under Shota, the alpha’s heavy balls resting between the omega’s tits framed by pretty pink nipples. The alpha’s eyes stare adoringly at his omega, noticing the reddened, bruised skin of his chest. Growling, he can’t help but guide his sopping wet, rock hard cock down on the flesh, focusing on rubbing more milky fluids all over the swollen buds.
“I’m gonna fill you up again and again, baby,” Shota growls. “Breed you so full of my pups…” He reaches a naughty hand down to his mate’s lower belly. “...right here, baby.”
Hizashi whimpers loudly, gathering himself enough to speak for the first time since his eventful awakening.
“P- please,” the omega begs. “Breed me, alpha. Fill me up inside, make me squirt on your knot, baby.”
Shota groans, leaning down to connect their mouths in a violent kiss. He shuffles back from his position on his mate’s chest, running a hand over the reddened skin to rub in the milky mess of cum and precum. Hizashi’s hands reach up to Shota’s hips, begging them to return, to have the alpha fill his mouth just once more. The dark haired man breaks the kiss to shake his head, diving back in to bite at the other’s plump bottom lip.
He’s not going to waste another knot outside of his mate’s cunt. Not after he begged for him to breed him so prettily.
He smirks down at the omega, taking in the downright filthy sight of him covered in a combination of their fluids, seeping into his skin and impregnating him with their shared scent.
Mine.
With a swift move, he flips the omega so he’s lying face down in the middle of their king sized bed.
As soon as his chest touches the damp mattress, Hizashi’s knees crawl up under him, rising his hips and spreading his legs apart to properly present to his mate. His hole twitches in need, globs of milky slick and cum leaking down between his cheeks towards the very tip of his red, swollen cocklet. Every panting breath, every shiver, every twitch, it is all for Shota. He cranes his neck to look back at his mate and smiles.
“I’m all yours, alpha. Breed me.”
Years ago, before they officially became mates, they agreed on not having children – not because they don’t want any but because they know their lives as pro heroes aren’t built for raising pups. Maybe in the future, when one or both of them retire, maybe then…
But that doesn’t mean, deep down, Shota doesn’t crave nothing more than to see his pretty omega swollen, plump and full with his pups.
He reaches down, massaging the soft skin of the omega’s ass, pulling the cheeks apart to reveal his gaping hole, spanking the flesh a few times to gape at his own red handprints on pale, flawless skin. Once again, he can’t hold himself back from burying his face into his mate’s most intimate parts, biting at the skin flaps that frame his hole, sinking his whole tongue deep inside and slurping every bit of cum and slick that leaks out.
A thought crawls its way into his brain, and he briefly pulls away to look through their bedside table. Hizashi watches him, panting harder and harder in anticipation when he sees his mate pull out their favorite plug.
Shota looks back at his mate, meeting his eyes with a dangerous smirk. “I’m not letting you waste any more of my cum.”
A whimper is punched from the omega, who can’t do anything but nod vigorously before raising his hips even more, begging.
Shota places his hands around the omega’s hips, the tip of his swollen, thick cock kissing the spasming entrance to his mate’s cunt. A deep need sinks it’s claws over him, and in one swift thrust he buries his whole cock inside. The intrusion is much smoother this time and the contractions that meet him suck him in to the very base. His balls sit snug right against his mate’s wet perineum, his sharp hip bones digging into the plush flesh of the omega’s ass.
The sensations are intoxicating. Shota’s low grunts do nothing to drown the high pitched whimpers and moans leaking from Hizashi’s drooling mouth. A switch is flipped in Shota’s rut-clouded mind.
With an animalistic, borderline painful howl, he begins a punishing pace. His hands grab fistfulls of muscular flesh, nails sinking and tearing into previously scarred skin as he uses his entire upper strength to push and pull his mate’s long, lean body back and forth on his cock. His hips keep pistoning with their own brutal force again, and again and again. The omega lets himself be manhandled, succumbing to the motions of his mate’s raw, borderline painful fucking.
The scent of blood fills the air, most likely from where the dark haired man’s sharp nails are digging into fragile skin. Shota’s alpha howls louder, deeper, releasing the feral need built up by stress and rut hormones for the past few days. One of his hands releases Hizashi’s hips in favor of reaching for a fistful of blonde hair, pulling the man’s head back. Hizashi’s moans become more guttural and raw, unable to form proper syllables as his throat is completely exposed to the open air. Lines of drool and salty tears meet the already moist pillow, joining the rivers of precum and slick leaking form between their bodies down to their bedsheets.
The bed shakes violently under them, and with one well placed thrust, the base gives in, dropping half the mattress to the carpeted floor. The new angle causes Shota to dig in his knees and feet in the mattress in an effort to keep himself upright, his thrusts punishing and unrelentless as his mate is unable to stop himself from falling back onto his Shota’s body.
At this angle, with Hizashi’s damp back pressed against Shota’s muscular chest, the alpha’s cock somehow reaches even deeper inside.
Crying out, the blond’s hands flail in the air until one lands on Shota’s shoulder while the other rests desperately on his own stomach. There, the feeling of his mate’s fat cockhead hitting his internal walls bulging out through his thin skin is all it takes for him to cum. Another thin, watery string of cum squirts its way out towards the forgotten pillow, joining the pool of combined fluids soaking it.
His walls clench onto Shota’s cock, forcing his knot inside without any previous warning. Shota’s whole body shakes and thrashes as he desperately grabs onto any piece of his mate's flesh he can find. His cock swells up impossibly big, and his fat knot locks inside his mate, releasing long streams of steamy, milky cum.
The alpha continues thrusting languidly into his mate. Squelching sounds from the place their bodies are temporarily locked together mix into their symphony of whimpers and growls. Hizashi uses his last bits of consciousness to grab onto one of Shota’s hands, guiding it to the place where his knot bulges out, swollen and twitching periodically inside the omega.
The feeling does nothing to undo Shota’s fat knot. He lets go of his mate, watching as his unconscious body flops back onto the bed. Between them, Hizashi’s whole desperately suckles at the base of Shota’s cock where his knot sits, begging for him to dive in impossibly deeper. He trails his fingertips over the abused edges of Hizashi’s cunt, gathering rogue trails of slick and cum and bringing them up to his face to hungrily lick his fingers clean.
He looks back down at his now unconscious mate and growls, letting his own upper body fall on top of him. His hips grind lazily as his fangs meet the junction between Hizashi’s shoulders and his sharp jaw. He delivers more claiming bites, licking over the smal trails of blood, and pressing kisses to the reddened, bruising skin.
Three more loads of cum are ripped from him before the aching hunger inside him is satisfied. He carefully arranges himself and his mate on the mess that is their bed – their nest – so they lie on their sides, carefully shoving his mate’s hair out of the way so he can keep nipping at the warm skin of the back of his neck.
Once he feels his knot give, he searches around for the forgotten plug, fishing it from the mess of tangled bedsheets and carefully shoving it inside his leaking mate. Small trails of cum and slick manage to escape, and Shota happily laps at them, humming deeply in approval.
Finally, in a sore, tired daze he lets himself fall back behind his mate, slinging his hand around the unconscious body and placing his calloused hand over the bulge in his mate’s lower stomach.
A few hours later, he wakes up to his mate’s arms wrapped around him. He’s purring, deep and happy, and Shota can’t help the self-satisfied smile that crawls onto his face.
“Morning, baby,” Hizashi whispers once he notices his alpha is awake.
Shota hums back in return, mind too hazy with hormones to produce a coherent response.
With a knowing, devilish smirk, Hizashi takes hold of one of Shota’s big hands and places it over his still swollen belly, whispering: “Can you feel your pups inside me, alpha?”
Shota’s eyes widen, his rut kicked back into gear. Screw his sore, overworked muscles. With a swift move, he wraps his free hand around his mate’s waist, flipping him flat on his back. The broken mattress protests under them, but none of them notices, lost in the other’s raw, feral eyes.
“I’ll take that as a ‘yes’.”
