Instinct

Summary:

Pre-heat sucks...But Ochako has a plan. She pulls the little slip of white fabric up over her legs and settles it over her freshly shaved mound, enjoying the way the soft lace feels against her skin and clips the matching bra in place to emphasize her other assets. The skirt Mina lent her shows off just a hint of her ass cheeks and just barely conceals the lingerie she picked out just for him...for Eijirou. Ochako takes a moment to consider her reflection in the mirror as she tugs the tight camisole down over her full chest. She's never worn anything like this in her life, but the dumb alpha just isn't getting the hint... Ochako is the only omega in their pack...and she has needs, okay??? Perhaps it's her approaching heat making her bold, but she wants that alpha and she's determined.

OR: Ochako's plan is thwarted in the best way possible...and they both get what they want ;)

OCHAKO

 

Pre-heat sucks...But Ochako has a plan. She pulls the little slip of white fabric up over her legs and settles it over her freshly shaved mound, enjoying the way the soft lace feels against her skin and clips the matching bra in place to emphasize her other assets. The skirt Mina lent her shows off just a hint of her ass cheeks and just barely conceals the lingerie she picked out just for him...for Eijirou. Ochako takes a moment to consider her reflection in the mirror as she tugs the tight camisole down over her full chest. She's never worn anything like this in her life, but the dumb alpha just isn't getting the hint... Ochako is the only omega in their pack...and she has needs, okay??? Perhaps it's her approaching heat making her bold, but she wants that alpha and she's determined.

Their pack has two alphas and they both live next door, but she only has eyes for Eijirou. The thought of those muscular arms holding her down and those thick thighs flexing as they piston a nice thick cock into her has her already slicking and a heated flush pinkening her cheeks even more than normal. Her pre-heat scent is strong, filling the room with the smell of sweetened peaches and for a moment she considers whether she should wear a patch or not when she goes to the apartment next door. Bakugou should be on patrol all night, leaving Eijirou home alone, providing the perfect opportunity to tell the alpha that she likes him and ask him to share her heat. She trusts Eijirou and knows without a doubt that he would take care of her.

It should be fine...she thinks. She tries a flirty smile in the mirror. Well...she'll work on it. But for now, she has an alpha to seduce. Her clit gives a little throb in anticipation as she opens the front door and walks next door.

She hesitates before knocking. Shit...is she really finally doing this? What if he rejects her? What if he slams the door in her face or thinks less of her? What is she supposed to say? She should have practiced first. Shit. Shit. Shit. Her hand hovers just over the door, poised to knock. 

She nearly jumps out of her skin when the door swings open almost violently and a low animalistic snarl greets her. Before she even registers what is happening, a large familiar hand snaps out and wraps around her wrist. She stumbles as she's yanked roughly through the doorway and her face slaps against a broad bare chest.

"Fuck, Chako...why do you smell like that?" Eijirou growls, his large arms locking around her and keeping her pinned against him. Her mouth goes dry and her eyes nearly roll up as the musky scent of an alpha in rut inundates her and immediately she slicks down her thighs in response. 

Ochako groans when her hair is suddenly grabbed at the back and her neck is forced to the side before a gentle breath over her scent gland makes her shiver. "You shouldn't be here right now, omega..." Eijirou rumbles from deep in his chest, tightening his arm around her waist. 

His pheromones wrap around her and nearly suffocate her with their aroused intensity, but she can't help but suck in deep inhales as she nuzzles forward against the heated chest in front of her. "Why?" she rasps, tongue feeling thick in her mouth as more slick drips from her.

"Can't control myself right now," Eijirou grits out through clenched teeth just before Ochako bucks with a gasp when a warm wet tongue suddenly drags over her gland. "Fuck, you smell so fucking good...you smell breedable, omega," he hisses and nips over the oily skin, sounding so far from his normal sunshine self.

"Alpha..." she breathes out, while he continues to suck at the gland and tease it with large fangs. Her slick thighs rub together with need and absently she thinks about the new panties and bids them a fond farewell. 

"Mmmmm...pretty omega," he growls and his other hand trails down her spine to her skirt. When he reaches the hem, he pauses. "You should leave, Chako," he whispers hoarsely as if he's clinging to his last thread of sanity.

She trembles as he teases his fingers against her ass, playing with the fabric. She tries to form the words on her tongue to tell him how she feels, but what comes out is, "Do you want me, Eiji?" She needs to be sure that they’re on the same page. 

"Always wanted you, Chako..." he murmurs softly, nuzzling against her gland. Ochako sighs in elated happiness and relief at the simple words. "But right now, I want to fucking ruin you...can't control it. Wanna shove my knot in that wet fucking pussy and stuff you with cum until you scream," he growls, the tips of his nails dragging over her asscheek.

The words rake over the hot coals burning in Ochako's belly and she moans as his scent blasts over her in a wave. She thrusts her hips backwards to meet his palm where it rests just over the fabric. "Want it, alpha," she whimpers as his fingers tighten over her ass in response.

She yelps as her hair is released and gravity abandons her as she's grabbed and lifted in the air, only to be tossed over a wide shoulder. "You're mine now," Eijirou snarls, sounding feral and unhinged as he prowls away from the door. 

She whimpers when the hand not pinning her down suddenly grips her plush thigh and rubs upwards towards where she's craving to be touched most. A flare of embarrassment heats her cheeks as his hand drags through the slick coating the skin. 

Eijirou's growl vibrates through her body and she whines when calloused fingers brush lightly over the drenched lace covering her. "You're fucking soaked, Chako..." he rumbles heatedly. "Were you hoping this would happen, baby girl? Because you're dressed like you want something, omega..."

He pets over the lace firmly for a few moments, fingers practically gliding over the fabric and making Ochako tremble harder. She nearly mewls when he wiggles a finger past the edge of the lace and teases at her wet folds. "Please..." she whines, incapable of anything more coherent.

"Who were you dressed up for, omega?" he demands, a note of warning in his tone that has more slick pouring from her at the pure dominance wafting off of him. She's never seen Eijirou like this and fuck, it's making her molten inside. 

"Y-y-you," she stammers, strained when his finger swirls over her entrance, threatening to dip inside her. "Wanted you, alpha...wanted you to notice me." 

She mewls when finally that thick finger stretches her open and sinks inside. "Oh, you have my attention, omega," Eijirou hisses and starts to slowly pump his finger. "You have my undivided fucking attention."

Ochako is squirming in pleasure as he twists his finger and drags over her sweet spot. She doesn’t even realize that they’re no longer moving as another finger dives past her panties and presses in next to the other with a squishing wet sound. His fingers feel deliciously thick inside her and it makes her wonder how his knot is going to feel…If his fingers are this big, how big is his cock? Fuck…  

“So tight, little omega,” Eijirou coos in a dark tone, twisting and spreading her walls in an almost exploratory manner under her skirt, making her wiggle and moan. “Gotta get this pussy nice and relaxed, don’t we?…” he purrs and he shuffles his arm just enough to pull the skirt up from over her ass. She cries out when he nips at the outside of her exposed thigh with sharp fangs. She squirms when he suddenly pulls his fingers free and she hears a lewd sucking sound. “Fuck, you taste good, baby girl.”

Ochako’s cheeks heat at the thought of him tasting her as she stares at the carpet below from over Eijirou’s shoulder, but then gravity leaves her once more and she lands over a soft surface with a whoosh of breath. She barely blinks and Eijirou is crowding over her with his massive body and crushing her lips beneath his. This isn’t a kiss as he licks and bites over her mouth…it’s a mauling…This close, his scent overwhelms her nervous system as he devours her like an animal and her body reacts in the only way it knows how. Her body starts to flare hot and sweat begins to saturate her tight clothes while slick practically drools between her legs. It’s with a startling moment of clarity that she realizes…He just kickstarted her heat. The thought is quickly waylaid as he tongue shoves deep between her parted lips and she’s helpless to deny it as he maps her mouth thoroughly. She barely notices when sharpened claws hook in the top of her shirt and shred it straight down the middle while a thick thigh suddenly shoves between her clenched legs to press right up against her core. Her hands fly above her to grab onto the comforter to brace herself as she bucks her hips to grind her sensitive pussy over it. She whines when the fabric of Eijirou’s joggers is in the way. 

Eijirou must get the memo because he pulls away slightly and gives her a surprisingly gentle peck over the lips before his weight disappears off of her entirely. Ochako groans as her body practically ignites from the inside and a sudden cramp has her curling upwards. “Alpha,” she whimpers and searches the dim room. Her eyes widen when Eijirou appears at the side of the bed. She’s no stranger to the beautiful sight of him shirtless, but her cramp is quickly forgotten at the sight of the monstrous cock hanging low and heavy between his thighs. She licks her lips unconsciously as he reaches down and gives it a singular stroke with a wicked smirk. Another cramp strikes her sharply in her lower body and a gush of slick flows from her. “Eiji…” she whines weakly.

She watches that smirk flatten briefly and Eijirou’s features scrunch in worry while his eyes search her for the source of pain, but then his eyes start to glint with something that Ochako can’t identify. He crawls forward onto the bed and she can’t take her eyes off of the cock swinging between his legs, desperate to have it inside her. “Chako…” he whispers heatedly and she feels the shift in the air, making goosebumps rise over her overheated skin. “Are you in heat, baby girl?” His growl is so low that she shivers at the tone.

She nods and clutches at her abdomen as it spasms painfully, tucking her legs up against herself. “Alpha, hurts…” she whispers pitifully.

She yelps as the backs of her calves are gripped and she’s yanked to the edge of the bed. “Come here, omega,” Eijirou snarls, his eyes nearly blackened with rut. A startled cry bounces off the walls when her panties are ripped away from her body and three fingers plunge inside of her, twisting through her contracting walls with a wet squelch. He doesn’t waste time as he starts to scissor her open with a low growl while she shakily pulls her knees to her chest to make more room for him. 

Her insides spasm with another cramp and she arches up off the bed, tilting her head back with a drawn out whine. The world is almost spinning around her as the flames of heat lick at her skin and hazy need consumes her mind. All she can think about is the thick knot she knows is waiting right fucking there, so close that she can practically taste it. The need to be locked over that knot while cum floods her womb is nearly unbearable, a scorching desperation that rushes through her veins and makes her keen with the ache inside her. She’s so focused on the thought of being bred that she doesn’t even register the words babbling from between her panting lips. “Alpha, please. Need your knot. Need your cum. Eiji…pleeeeeeeeeeease…”

Eijirou’s vicious snarl interrupts her begging, a silent demand that she submit to his ministrations. “Be patient, omega,” he commands through gritted fangs as he stretches his fingers wide within her. “Once I start, I’m not stopping, baby girl. I don’t want to hurt you, no matter how much I wanna stuff your tight cunt and make you sloppy with my cum.” 

Even through the aroused fog encompassing her, she recognizes that Eijirou is clinging to his last shreds of chivalry. A warmth that has nothing to do with heat spreads little tingles through her body. A stuttered exhale leaves her when a fourth finger wiggles inside her and his fingers curl upwards towards her abdomen and start to rake over the sensitive spot. Fuck…it feels so good that she almost misses his low grumbled words.

“Gonna pup you, omega. Fuck a full litter inside you…”

Ochako groans at the heated promise, clenching down hard, and her eyes meet the burning coal black irises staring down her with a hunger that she can’t describe. Eijirou’s other hand wraps around the back of her thigh bruisingly as he starts to drill his fingers inside her, making her squeal and try to buck under his hand. “You like that, omega?” he growls with a wicked smirk that makes Ochako’s knuckles turn white where she’s gripping the sheets. “Yeah…you’re gonna carry my fucking pups like a good girl, aren’t you…you’re gonna let me pop this fucking pussy with my fat knot and stuff you with cum over and over again until you’re begging and crying.”

Ochako can’t even choke out an answer through her stuttered moans as Eijirou pummels her g-spot with effortless accuracy and her belly tightens at every snarled word. She NEEDS it…NEEDS her alpha to breed her…NEEDS his pups growing inside her...NEEDS his cum and his mark.  Ochako’s little omega fangs throb in her mouth at the same tempo as her pussy as the coil inside her tightens, completely drowning out the cramps. This is HER alpha. She’s gonna be so fucking good for him if it’s the last thing she does. Her teeth clench so hard that they feel like they’re going to break as his thrusts harden inside her and beat against her puffy pussy lips. 

CUM FOR ME !” 

Ochako screams as the sudden command slams over her and all of her nerve endings explode at once, the coil inside her snapping and blinding her with its intensity. Her body shakes uncontrollably as warm wet slick splashes over her thighs and over her alpha. Tears spring to her eyes while her pussy spasms around the thick fingers still plowing through the clenched muscles. Ochako has never been commanded a day in her life and she feels dizzy from the most intense orgasm she’s ever had and the overwhelming scent of dominance wrapping around her like a vice grip. More slick pours from her when a secondary wave of pulsing pleasure riots through her body, making her squirm and sob. 

Her breaths almost hurt with how hard she’s sucking them in when those fingers finally yank free. Her watery eyes are still clenched closed so she doesn’t anticipate it when hardened claws suddenly latch over her waist and she’s jerked further down the bed and forcefully shoved to her belly, causing her legs and feet to dangle over the tall bed. Her skirt is practically ripped from her body with one violent rip. She yelps when a hand wraps in the back of her hair and tugs her head up from the mattress, forcing her up onto her elbows. Warm skin grazes her back and that thick cock grazes her ass cheeks as Eijirou leans over her. Her body twitches as another cramp contracts her belly, making her whimper at both the pain in her abdomen and the strain against her scalp. Hot breath ghosts over her ear before scalding lips latch over her scent gland and suck hard at it. Ochako’s moan sounds loud even to her own ears as Eijirou bucks his hips forward against her ass and that thick cock brushes between her cheeks. He nips at the gland with his fangs teasingly and Ochako squirms with want. “Smell so sweet, baby girl. Gonna break this fucking pussy just like all of my rut toys. Been dreaming of filling your cunt for years. I’ve spent every fucking rut imagining you squirming on my knot and begging your alpha for more,” he murmurs against her skin between sharp little bites. “You offered yourself up like a juicy little sacrifice…Now you’re mine, omega.” 

Ochako shivers at the heady words and wiggles when she feels Eijirou’s hand slip between them to grab his cock. Her insides ache near constantly now and slick drools down her thighs in a steady stream. She wants to tell him that she’s been dreaming about him too, that she’s craved only him since she presented in high school…but the words are cut off when his thick cockhead presses through her dripping folds and she’s forced to stretch around his girth with a mewl. 

 

EIJIROU

 

She’s more perfect than he ever imagined… the brief lucid thought drifts through Eijirou’s mind as he sinks deeper into tight silky heat. Ochako lets out the most delicious whimper when he winds his fist tighter into her hair, tugging her back into a sinful arch. Molten insides practically pulse over his cockhead. He can’t resist as her sweet peach scent calls him on an animalistic frequency that makes his ears rush…His hips slam forward, brutally impaling her soaking pussy with one decisive thrust that makes his omega squeal and thrash. He grips tightly to her waist with his other clawed hand to keep her pinned in place and snarls as her walls suck wantonly at his shaft and chubby pussy lips tease at his already half-formed knot. 

Ochako quivers and whines like trapped prey as he draws his hips back slowly, watching as each shining inch is revealed, dripping with her slick. He can smell the needy heat practically radiating from her and his eyes want to roll back as he rams his cock back through her folds. His instincts scream at him as her slutty mewl cuts through the air. He bites his lip until it’s bloody at the sight of his omega laid bare for him. He releases her hair only to latch hardened claws over each of her asscheeks to spread them wide to watch as he starts to pound inside her. Slick practically gushes around his cock and he snarls as it coats him completely from the waist down.

“Alpha!” She keens, muffled by her face in the comforter as she clings to it for dear life. The sound shoots straight to his cock, spurring him to release her cheeks, grip her hips and yank her back on each of his thrusts. She squeals louder as he rails inside her and his fangs ache at the sound. 

His lips curl up when Ochako suddenly bucks her hips up against his hand and she scrabbles at the bedding while clamping down hard over his cock, her entire body going almost rigid with a guttural moan just before her walls flutter wildly and slick jettisons around his cock to coat his front and soak the carpet below. “That’s it, omega…fucking squirt for me,” he snarls and activates his quirk, making his cock swell and harden further within her squishing cunt. He watches her nails lengthen into claws and begin to shred his bedding as she writhes and wails, more slick spurting from her as he holds her down and bucks into her. His knot pulses with how swollen it is and his balls threaten to explode with every one of her hoarse cries.

BREED. The word blares through him like a siren. 

“Alpha! PLEEEEEEASE!” She begs through heaving breaths. 

He knows what she wants. Knows what she needs. Her skin feels like fire as he grips her tighter and pistons faster, making the headboard slam against the wall so hard that bits of plaster are starting to chip away from the impacts. “You need a big fat knot, baby girl?” he growls, mating venom dripping over his tongue and his enlarged fangs making his gums feel tight. “Need alpha to breed this fucking pussy?”

His omega is tearing at the sheets in her frenzy. Soon, his bedding will be nothing but shreds and fluff, but he could give a shit less as his knot kisses against those drenched lips. His balls feel like weighted pendulums between his thighs as they swing with every thrust. Fuck her hard. Fuck her so hard she can’t walk away. Stuff her with cum. Breed her. Mark her. Pup her.

He roars as he rams his hips forward so hard that the headboard slams through the wall, chunks of white blasting outwards as his knot sinks into his omega’s tight slick hole and catches within her walls, swelling to lock them together. Ochako’s legs kick backwards, but he keeps her in place as he grinds forward and sinks the knot deeper into her spasming womb. She clamps down tight over it and his release barrels through him like a bulldozer, whiting out his vision as his balls draw up and cum jets from his tip. He rocks the knot within her as she squeezes down tight over it, milking more cum to pour from his slit. “Good girl,” he groans, while she sucks in harried breaths and whimpers as she’s filled.

The more cum that pumps into her, Ochako’s limbs start to loosen and eventually she goes completely limp with a sated hum. A little bit of lucidity clears some of the feral fog when a foreign sound catches in his ears…a low sweet vibration. He lets go of Ochako’s waist, fingers back to normal and rubs them up over her sweat-slicked back and his eyes widen to feel that vibration radiating from under her skin. She’s purring…Ochako is purring for him. Omegas only purr for their mates and Eijirou knows then that without a doubt…she belongs to him. He strokes over her skin lovingly, kneading at any tense muscles just to listen to the sound grow louder. His sweet omega has her face turned to the side where he can just make out relaxed features, dark lashes resting against her cheeks and hiding milk chocolate eyes. He knows she’s not asleep, but is floating high in omega-space, an intensified afterglow when an omega is knotted. He leans down to press a kiss between her shoulder blades as his knot starts to deflate and slip free several minutes later. 

When he pulls his hips back, Ochako stirs, eyes blinking groggily as if waking slowly from a deep sleep. Eijirou doesn’t mind the mess as he crawls up onto the bed beside her and grips under her arms to easily tug her up until her feet are no longer over the edge and she’s curled into his side, facing him. Her skin feels feverish, sweat making it shine as he eliminates any space between them and tucks their necks together for the first time. Ochako’s moan is heady as their oils mix together and their scents combine thickly in the air around them. Eijirou resolves that from now on, his room will always smell like this…their scents intertwined and saturated with the smell of their coupling. A chuff of satisfaction launches from his chest as he nuzzles into soft sweat-damp hair and Ochako’s purr radiates between them.

It won’t be long until their next waves come, but for just a moment, Eijirou enjoys the brief lucidity to press kisses over Ochako’s face, just happy that she’s finally here in his arms. Ochako has always been his endgame, pretty sure he’s been in love for years…and while he’s confident in most areas of his life…Ochako was always the shining star that he was hesitant to reach for. He didn’t want to risk pushing her away and has been waiting for any kind of sign that maybe they could be more. 

However, all of that flew out the window when the sweet scent of ripe peaches and cream barreled through his door and dragged his rut right up to the surface while he’d been completing preparations to barricade himself inside for the duration. And fuck…what a sign it was…wearing a slutty skirt and tight top, looking like every lewd fantasy of his come to life. He couldn’t get her in his arms fast enough, his alpha demanding that he take her right there on the damn doorstep.

“Alpha,” Ochako coos softly, interrupting the replay in his mind as he nuzzles further into her neck with a deep inhale. Fuck, he’ll never get tired of hearing her call him that.

“Omega…” he rumbles sweetly in response, smirking at the little shiver that rolls through her delicate body. He rewards her with a light nip to the side of her neck as he reaches down between them and palms between her thighs. She willingly spreads her legs to allow him unfettered access, his alpha smug as hell as he rubs through the mess. She tucks her face closer to his chest, but tilts her eyes up at him. The beautiful milk chocolate of her irises is nearly completely absorbed by the pupil as their eyes meet and Eijirou’s cock starts to fill once more at her needy expression. She’s not quite in a wave just yet, but he can smell it approaching as her scent turns almost syrupy, like warm peach cobbler. Her hips wiggle, grinding down over his hand, the purr in her chest increasing in volume. “My pretty baby…” he croons softly, swirling his fingers around her clit and his instincts start to rev up in his mind and his thick cock throbs.

Ochako sighs when he presses firmly over the nub and thrums over it, making her hips buck and twitch. Her purr stutters, cutting in and out with her gasping breaths. He feels like the cat that got the cream when she whimpers and curls in on herself, knowing that he’s the only one who can give her what she needs. He’s going to take such good care of her. He’ll be the best fucking alpha. 

In one swift move he rolls them so that she’s on her back and he’s kneeling between her spread legs. He grabs both of her ankles and raises them up over his shoulders as he bends over her with a feral snarl. He rears back a little when Ochako smirks and gives a girlish giggle that he wasn’t expecting.

He’d thought that Ochako was already sunk deep into her instincts, but the smile on her face suggests a surprising amount of clarity, despite her sticky sweet scent and sweat coating her body. 

“What’s so funny, omega?” he growls out of sheer curiosity while struggling to keep his own instincts at bay.

Ochako’s smirk disappears with a whine as she tries to curl upright when her own body demands to be satisfied. “You’re so hot when you’re riled up, Eiji…” she grunts faintly through the pain.

A surprised laugh barks from him. “Is that so?...” he teases through enlarged fangs and dips her into a deeper press just to lick over her plush swollen lips. “You like it when I breed you like an animal, baby girl? When I can’t get enough of your little cunt squeezing over my cock? When I want to bite your pretty skin and leave my marks all over you?” he murmurs against her lips as their humid breaths tangle together.

Her pupils expand further outwards and she sucks in a gasping breath at his words just before he swallows her whine by slamming their lips together and claiming her mouth in a ravenous kiss. He can feel her trembling with need below him as he braces on one hand to reach between them. She screams into his mouth when he rams his cock into her pulsing heat with a grunt. When he leans back just slightly, her face is contorted and eyes lewdly crossed at being so brutally stuffed. He braces against the mattress and lifts his hips just to rut down into her with another violent thrust that scoots her upwards over the mattress. With shaky hands, she reaches up and braces them against the headboard with a loud squeal. 

He feels wild and unchecked as she clenches so desperately around him, his own cum and her slick frothing around his buried cock. He snarls as he claps a hand over her mouth and grinds so deep that his cockhead rams against the barrier to her womb. She wails behind his hand as her eyes clench closed and her nostrils flare outwards. “Mmmmm that’s it, scream for me, omega…cry on my fucking cock,” he commands in a low voice that sounds almost inhuman. He keeps his hand planted when he pulls his hips back and rams back inside, forcing more delicious sounds from her. Her teary eyes fly open when he leans further over her and tucks his face into her neck to graze his fangs threateningly over her gland. “I should have made you mine years ago,” he rumbles in low tones against her skin. “Fucked you so full of pups that you’re forced to stay in my fucking bed…” He licks and sucks over her gland as he starts to pump his hips with hard deep impacts. Ochako moans against his hand, her hot panting breaths gusting over his hand. “You and this perfect fucking pussy are mine, omega,” he snarls viciously as he starts plowing into her hard and fast. “You’re gonna fucking bathe in my cum, baby girl. Gonna make you smell like me and you’re gonna wear my fucking bite. Gonna fuck you pregnant, omega.” 

He ignores it when Ochako’s pussy pulses and constricts tightly around him, her slick spraying around his pistoning cock as her eyes roll into the back of her head and she screams helplessly behind his hand and claws at his headboard as it once more bangs against the wall. “You’re gonna take it all like a good fucking omega…” he rasps against her neck as his balls start to ache from how full they are. Fuck. Breed. Mate. Fuck. Breed. Mate. The words cycle through his head as he hardens his cock just to stave off his impending orgasm. He needs his balls full to bursting so that when he sinks his knot inside her tight little cunt, his cum bloats her with the volume. He’s gonna make sure it soaks in nice and deep. 

“Fuck, omega. Gonna breed you so well. Gonna fill your tight little cunt up,” he swears darkly. His knot hammers almost bruisingly against her pussy lips as he fucks down into her mercilessly while she sobs, tears and sweat dripping down over her forehead and cheeks. His balls sway heavily below him as he becomes mindless and his cock swells further, stretching her loosening walls to make them excruciatingly tight once more. She writhes beneath him deliriously, her nails digging into the wood of the headboard as more plaster flies down to coat the bedspread and land in her hair. He has the brief amusing thought of them fixing the wall later before his landlord finds out, but the thought is quickly lost in the feral haze of his mind.

His roar is deafening as it becomes too hot and too much as she once more gushes with yet another orgasm and clamps down on his cock. It takes three tries of him ramming straight downwards to fuck his knot into still spasming muscles as her muffled wails ring in his ears. He grinds down deep, working his knot and groaning when she squeezes over it so tightly that he fears she might break his cock. His balls nearly explode under the pressure and cum shoots from his cock like a pressurized hose. His hips roll and buck with short sharp movements as her sticky peach scent flares brightly with satisfaction at being filled. Fangs throbbing and venom coating his tongue, he grips tightly to her cheeks and jerks her head to the side. He strikes when the instinct slams over him so powerfully that he’s helpless to resist. His jaw opens wide and fangs pierce the tender flesh of her mating gland, filling his mouth with her sweet pheromonal oil and savory tang of blood. Instantly, a wave of bright light flashes in his eyes and a euphoria he’s never known washes over him. His teeth sink deeper at the intense sensation, more cum flooding from his cock. Ochako convulses, bowing upwards even under his weight as he marks her as his forever. It feels like hours when in actuality, it’s probably only a couple of minutes as they stay suspended in that moment of absolute bliss. 

Only when the ecstasy starts to taper down and the light recedes, does he release his jaw and pull his teeth from torn flesh, blood still coating his teeth and lips. He licks over it, eyes still fluttering at the sweet perfect taste of his mate. Ochako is limp and breathing hard when he gently pulls his hand away from her mouth, palm coated in her saliva. Her body is quivering and chocolate eyes are fluttering wildly while her scent starts to change around them, taking on the woodsy notes of Eijirou’s own scent. His cock continues to fill her womb and he grazes his knuckles tenderly over her cheek while she rides the high and the bond starts to snap in place. Already, he can feel shadows of her wrung out emotions tangling with his and his smile is broad when her purr vibrates from her chest, bright and loud.

He tucks himself over her, an obsessive need to feel all of their sweaty slick skin touching. Complete satisfaction practically beams through the bond as he licks over her bloody skin, knowing that his saliva will allow the wound to heal cleanly and the scar to deepen as a permanent mark of their connection. 

He lets her soak in the afterglow as he pets over her skin. “So perfect, baby girl. My sweet mate…taking me so well. We’re gonna be a little family. Gonna treat you so right and spoil you rotten,” he praises. “You’ll be such a pretty momma to our pups. They’re gonna be beautiful, baby.” 

She hums happily over the sound of her purrs, a soft little smile curling her lips up. His rut may be settled with the mating, but he knows that her heat won’t be satisfied just yet, her need to breed will take precedence, but right now he’s reveling as more and more of his mate starts to trickle over the bond. She feels happy…feels complete and fulfilled. He slowly leans up to let her legs stretch out around him and begins to massage tense muscles. Her claws are still embedded in the headboard and he reaches up to disentangle them from the wood.

“I can feel you, Eiji…” she slurs quietly after a few moments of just the quiet sounds of her purring.

He smiles fondly and his cock twitches within her at her soft words. He’ll never get enough of her. This he knows without a doubt. “I can feel you too, baby girl.”

“You’re feeling awfully smug right now, alpha…” she teases, voice raspy from all of her screaming.

Eijirou chuckles and leans down to nuzzle their noses together. “Of course I am, omega. I have the prettiest, sweetest, most perfect mate. I’m so fucking lucky,” he purrs.

Suddenly, Ochako’s eyes crack open and she gives him a sort of muddled frown that instantly has his guards flying up with worry. Confusion leaks over the bond and Eijirou leans back, watching as Ochako’s nostrils flare, scenting the air. He huffs in a deep breath, trying to figure out what’s pulling her out of their little bubble of intimacy.

“Do you smell that?” she asks faintly.

He sucks in another deep inhale. All he can smell is their combined scents and the salty notes of his cum. “What is it, baby girl?”

Abruptly, her purring cuts off and a surprisingly menacing growl has her features scrunching, lips pulled back and little omega fangs on full display.

Eijirou hears the front door slam and he cringes. Shit… His own instinctual growl rumbles from his throat as the scent of another alpha wafts into his nose and his knot softens in preparation for a fight to defend his omega and his rutting territory.

“Shitty Hair! Why the fuck does it smell weird in here?!” The shout pricks in Eijirou’s ears as a red haze of rage filters over his vision. “Thought you were preparing for your rut, dumbass!”

As Eijirou slips free of the warm hole that had been holding him hostage, he’s on his feet in moments and snarling at the door when it flies open unceremoniously. He bares his fangs as his scent flares outwards in warning. 

Katsuki’s eyes fly wide at the sight of them both and the destroyed room. “Holy shit…” he mutters under his breath. A feral snarl rips from Eijirou’s chest, all of his instincts screaming at him to remove the competing alpha and intrusive scent from his space and away from his mate. He stalks a few steps closer to Katsuki.

For the first time ever, Eijirou watches Katsuki’s face contort into a nervous expression and he puts his hand out in a placating manner. “It’s okay, big guy. Calm down,” he says in a neutral tone and reaches slowly for the door handle. “I’m leaving. Gonna go stay with Deku for a few days and give you guys some space…” he says in an uncharacteristically soothing tone, his normally strong smoky scent kept carefully in check and as non-threatening as possible. Eijirou blinks and a little clarity leaks through his aggression when Katsuki tilts his head just slightly, showing his submission. A little bit of tension bleeds from Eijirou’s body and his lips once more tuck over his protruding fangs, the persistant growl cutting off. Katsuki slowly backs away, pulling the door as he goes, but keeping his eyes carefully on Eijirou until the door once more settles between them. 

“Just so you know, I ain’t helping you clean this mess up though! It’s about fucking time you two figured your shit out!” he hollers through the door after it clicks shut. Eijirou chuckles darkly in response, but is only able to loosen out of his defensive posture once the scent fades, lost to the heady mixture of the newly mated couple.

He blinks when he turns back to find his pretty mate surrounded by a makeshift nest of shredded fabrics and stuffing, fast asleep and curled in a little ball at the center. Apparently, the alpha standoff hadn’t been enough to overcome the heat exhaustion and he smiles at the precious sight of Ochako curled in a nest made in the middle of his den…right where she belongs. He pads with quiet footsteps back to the bed and carefully climbs over the haphazard walls that were quickly put together while he was busy posturing. He’s careful not to disturb her as he lays just behind her and slowly slides his arm over her. Even unconscious, he smiles when she instantly scoots back to eliminate the remaining space and clutches over his arm, trapping him in her embrace. A contented chuff leaves him when he tunes into the bond and finds his omega happy and restful. He’ll let her get her rest while she can… His palm spans over her belly protectively and he closes his eyes.

They fly open only a moment later though as he brushes his palm over her skin and her back nestles further against his abdomen. The sweat has dried over her soft skin and it’s relatively cool to the touch…meaning that her heat has miraculously abated. It shouldn’t be over this soon…UNLESS…

 

Eijirou grins as the revelation settles over him and he tucks his nose into Ochako’s neck just to be absolutely sure of what his gut is telling him. Sure enough, her scent is already tinged with the milky scent of pregnancy. He nuzzles further over his bite and licks over it tenderly. Pure happiness radiates through him as he pulls his little mate closer. She doesn’t wake with the movement and his chest rumbles with pure pleasure.

“Love you, Chako,” he whispers into the soft strands of her hair. “Can’t wait to start a family with you, baby girl.” His eyes finally close when her purr resonates strongly between them, creating a soothing background to their even breaths while their scents settle over them like a warm blanket.
