Summary: - Estrus is such an annoying biological phenomena for Katsuki. He wishes he could do without it, though he knows it's part of being a healthy Omega. He doesn't mind sex, on the contrary; what he despises is the frankly ridiculous amount of slick he produces and how hot he gets. Oh, and the Alpha which are sent to his room during his monthly cycle. -
Sweat runs down Katsuki's body, collecting in every dip and crease; small pools of mouth-watering sweetness glistening on his alabaster skin. It's brought forth by the fire crackling inside the twin marble hearths, strategically placed at opposite sides of the spacious room — their warmth vital in keeping the still-present winter chill from crawling in past the thick stone walls —, as well as by his current physical state.
The expletive leaves him in a hoarse exhale, one of many he's said in the past few hours, or days, really. Estrus is such an annoying biological phenomena for Katsuki. He wishes he could do without it, though he knows it's part of being a healthy Omega. He doesn't mind sex, on the contrary; what he despises is the frankly ridiculous amount of slick he produces and how hot he gets. Oh, and the Alpha which are sent to his room during his monthly cycle.
Month after month, since his first Heat at the age of twelve, he's visited by Alpha males or females or something in between. They would approach him in his own private space during a delicate time, hoping to help him through it or trying to force themselves on him. All of them candidates chosen by Katsuki's parents — the King and Queen —, who are adamant he gives the throne an heir before he's given the crown. Of pure royal blood or not didn't seem to matter.
Katsuki rejected all of them.
He would rather deal with his Estrus on his own, than give up control over his own body to some entitled Alpha who thinks they can mate and claim him.
That's exactly why he's presently drenched in sweat and slick, kneeling on his luxurious bed of soaked linens and furs, as he slowly gyrates his hips on a custom-made fake cock. It's the second wave of need of the day, on the third day of his new cycle. The remains of a late breakfast are forgotten on the round table nearest to the heath next to the bedroom's door, the servants wisely postponing its retrieval for their own sake. This is the point of his Estrus in which he begins to get impatient, explosive, territorial; the point in which it's dangerous to barge in his room uninvited or unannounced. Everyone in the castle knows, some have heeded the warnings while some have learned first-hand, the hard way.
Katsuki runs his hands through his hair — wild, spiky, ash-blond —, pulling on it, humming in approval at the tiny sparks of pleasure feeding off his craving. His hands sliding down his neck; he circles the protrusions there, his scent glands hot to the touch and pumping out oil which mixes with his sweat. Digging his nails in them makes him moan, makes his cock throb and his cunt tighten up around the toy he's fucking himself onto. It feels great. It doesn't matter if Katsuki's friends keep telling him how an Alpha biting a main gland is guaranteed to be the best orgasmic experience for an Omega in Heat.
It's the height of bliss.
He knows that. He's also aware of how such an act involves claiming, however temporary, and Katsuki is not about that.
«KATSUKI! What the fuck you think you're doing?!»
The richly-carved double doors dividing his inner bedroom from the anteroom slam open, the heavy wood cracking against the stone wall with a thunderous noise.
Appearing in the threshold is none other than Bakugou Mitsuki, the Queen and Katsuki's mother — one of the only two people who would dare barge in on him at this time; the other being his father the King —. Her bright red, fur-lined cloak whisks about her back in her brisk walk and abrupt halt. Her long, blonde hair inelegantly sticks out of what had been an artfully-made braid. Her crimson eyes are incandescent coals of fury.
«What d'ya think 'm doin', hah?» Katsuki responds brazenly, unaffected by the sudden presence as well as the accusation. He sounds barely winded despite being at the height of his Estrus.
His mother is also uncaring of his state, too used to see him naked, flushed and dripping. She snarls his way, plump lips pulling back to show her teeth. «Why was your pet outside your quarters?!» she demands. «And in this state! He's in Rut!»
She yanks on a chain with a sharp tug of her wrist, hauling a lump of dead-weight forward to crumple on the floor at her feet. The heap of shivering flesh is whimpering, barely able to lift his head from the polished stone to fix glassy green eyes at Katsuki.
«M-Master...» he whines, scrambling to kneel and bow, his forehead touching the floor. «I-I-I'm s-sorry…! Please—» he chokes on a sob but doesn't try to continue talking.
«You have some nerve, Deku...» Katsuki says, not bothering to stop his ministrations nor outright acknowledge his mother. «You know you deserved it.» His own crimson eyes flash dangerously, fixed on the shivering form asking for forgiveness.
His thighs and hips continue to work him over his toy tirelessly, teasing himself, bringing himself closer and closer to orgasm. He changes angle, just a tiny bit, enough for his inner sweet spot to feel some much needed friction. His hands don't still either, rather they roam his toned body, damp with sweat and smelling of delicious caramel. He gives a couple of lazy strokes to his flushed cock, the precum joining the mess of fluids pooling in the furs under him. He moans out a curse, unrestrained.
Deku flinches, noisily inhales his scent, which permeates every corner of the room, shudders.
The Queen clicks her tongue, irritated. «Whatever, I don't care what you do with him, but don't leave him out unchecked,» she says turning on her heel. «And don't waste a Rut, you're an Omega, Katsuki, you need an heir.»
«No, you need one, old hag.» Katsuki barks out a laugh when Mitsuki pauses mid step at the remark, but doesn't deny the statement before stalking off in a flurry of rich fabrics and bitterness.
His mother gone, he's left alone with Deku.
The 'pet' is a slave boy eight winters younger than him; the Queen had bought him for Katsuki after his last… mishap — if the severing of an unwanted, knot-ready cock via very sharp teeth and the consequent death of such cock-owner can be called a mishap — with a previous royal-born Alpha. It wasn't a reward, more of a last-ditch effort in trying to make him bear a child to continue the Bakugou line.
( «If you refuse to submit and mate with anyone of our choosing, then fine,» Mitsuki had said, an aura of tired anger about her as she sat on her throne. «Take this slave and train him to your liking.» )
Katsuki now stares at Deku. The slave's still curled up on the floor and careful not to lift his eyes, though all his other senses are clearly attuned to Katsuki's cycle. There's an obvious flush spreading along his upper body and beads of sweat catching the flickering light from the hearth closest to him. The boy's huffing is loud, no doubt he's breathing in Katsuki's pheromones through parted lips; his sniveling is equally as loud but Katsuki quite likes the sound of it. The looks of it.
«Look at me, Deku,» Katsuki orders. He stills his hips, groaning at the satisfying feeling of being full at his own conditions even if it meant enduring the annoyance of his Estrus on his own.
Deku's watery eyes snap up, dilated pupils growing to further eat away at verdant green as he's given permission to bask in the sight of his Master's nudity and enticing appearance. «M… Master...» he whines.
Katsuki smirks, pride and ego singing in his veins at the venerated look. Yes, you know your place. You're mine. «Did you learn your lesson, you filthy mutt?» He growls, so unlike a common Omega. «Next time you try to fuck me, I'll wring your neck.»
Deku cowers back and Katsuki thinks if the tail stuck up his ass was real, it'd be curved between his legs in fear — the image alone sends a thrill along Katsuki's spine nonetheless —. The boy nods, words lost in his dread of further reproach. Despite it, he's still abundantly erect; his cock an angry red verging on purple, precum leaking down the length the same as Deku's tears do down his freckled, blushing face.
How cute, Katsuki purrs at such a delicious picture; his pussy and cock both delight in it. He unconsciously grinds down on the fake knotted length; it's doused in his juices and just this side of not quite enough, not when he has his own — trained, however at times misbehaving — living, breathing plaything standing at the ready a few steps away.
«Come here, mongrel,» Katsuki says. One hand abandoning the teasing of a puffy, dark pink nipple to beckon Deku forward.
Deku crawls forward on all fours. His youthful cock hanging between his legs, heavy and oozing and restricted by a handcrafted dark-green leather band engraved by magic symbols sealed around it. The boy chokes on a sob as it sways with each movement. He halts, limbs shaking, hips lowering to brush the lush carpet in search of quick, momentary relief.
He freezes when Katsuki snarls in a warning to cut it out.
Katsuki bets it hurts, after two days of being denied the bliss of cumming, during a Rut and in the vicinity of an Omega in Heat above all. He licks his lips, more turned on by the minute, his burnt-sugar scent thickening until it overpowers Deku's peppermint-musk one. He looks down upon the Alpha boy's pathetic figure. The slave has crossed the distance; he's now kneeling next to the large bed and wordlessly handing Katsuki the chain connected to the collar around his throat.
«Good puppy.» Katsuki is magnanimous enough to praise him. He takes the chain and gives it a firm tug, smirking when Deku yelps and tumbles forward. «Say, Deku, are you sure you learned the lesson, mh?» He asks, a cutting edge to his voice; a threat hiding behind his smile.
Deku whimpers, but faces him head on. «Y-yes Mas-Master… I'm sorry, I, I won't d-do it again… please-» his big green eyes stare up at Katsuki, his hands fisting the furs to keep them from visibly trembling- «forgive me! P-please let me hel— l-let me be of use to you, Master!»
Katsuki raises an eyebrow at the choice of words. Smart boy, he thinks, keeping a careful handle on his mask of indifference. «We'll see about that.»
Katsuki raises on his hunches, the hand not holding Deku's leash gingerly slips the leather toy out of his dripping cunt. He sits down among the wet furs. He sighs at the emptiness and his walls clench on nothing, but it's fine, he can wait awhile; the thought of playing with his pet will entertain him until he couldn't wait anymore. He dangles the fake cock in Deku's face. Katsuki openly laughs at him when he flushes a darker pink, his eyes going hazy and his tongue lolling out like a actual dog at the strong smell of Katsuki's slick, his Estrus pheromones.
«Yeah, ya like that, huh Deku?» Katsuki mocks him. He distends one leg toward Deku, sensually curling the heel of his foot behind the slave's nape; he draws him close to his throbbing groin. «My scent.»
The prize any notable Alpha in this corner of the continent dreams of having for themselves.
He is of royal standing. Young, unblemished, fertile, primed to be bred.
Yet this pitiful and somewhat plain-looking boy is one of the three people who's ever been allowed so close to his womb. One of the three people whose seed has ever been welcomed in the innermost part of Katsuki's body. Katsuki rejoys in knowing that; in the wonderful sense of retribution.
«Yes...» Deku mewls, neck straining to get closer to Katsuki's wet center. Mouth parted, tongue out, huffing against the tantalizing plump folds. «Master's… scent…! Omega.»
Katsuki hums, a shiver running up his nerves as he feels the breath fan over him. He pulls on the chain linked to Deku's collar — a lovely piece of work, really. Top quality leather of a beautiful dark green, to match the boy's cock band, and white; four decorated silver hoops and a ring at the front where the chain is latched; small rubies studded all around —, taking the boy by surprise when his nose ends up smacking against the base of Katsuki's cock and his mouth right against his swollen clit.
Deku moans, wanton and overwhelmed by the closeness to the bitter-sweet smell of his owner.
«Suck,  ya dirty mutt.» Katsuki's order hardly leaves his mouth before Deku's following through with it.
The boy's tongue is on him in an instant, swiping at his pussy from bottom to top, licking up his juices and visibly shuddering in pleasure at the taste — the first he's had in weeks —. He pauses for only a moment to savor it, then he gets to work in earnest. Deku's lips and tongue trace his folds, sucking on them and lightly brushing them with his teeth, so well trained on what his Master likes.
«Fuck! Yeah, Deku!» Katsuki rewards him with a loud groan, head thrown back.
He yanks on the chain still in his hand, legs spreading more as he pushes his hips forward to smother the Alpha slave with his cunt. Deku whines into him, lips enveloping Katsuki's sensitive clit; he flicks it, grinds the tip of his tongue to it just right to make Katsuki's legs twitch and come to wrap around his neck. He feels small hands rest low on his thighs, thumbs gently caressing and kneading his skin, smearing his slick and inching closer to its source.
«Damn— ah!— it…! Yeah, yeah there!» Katsuki moans. Deku's mouth moves lower, tongue slipping inside Katsuki's sopping wet pussy, folds pulled apart with aide from his fingers. «Shit!»
Deku responds in kind, keening in hunger, vibrations from his sounds sending jolts of pleasure up Katsuki's spine. His nether regions both throbbing, yearning in need for more. The fever from his Estrus has reached mind-numbing heights; a part of his brain wants him to beg to be filled, so bad tears build up in the corners of his crimson eyes. He growls, pushing back the weak Omega voice in him and tensing.
«Off,» Katsuki rasps Deku's way, rage turning his voice to gravel. The boy doesn't seem to hear him through his Rut-addled mind and it serves to anger him further. «I said OFF!»
Katsuki snarls, wrenching Deku away from his groin and hauling him on the bed with a powerful tug, uncaring of the boy's pained cry. He settles over the back of Deku's legs and pulls on the chain, the slave's flushed upper body lifts from the slick-soaked furs.
«So… sor… ry, Mas-Master…!» Deku wheezes, scrambling to use his arms to ease the pressure on his windpipe. «I-I'm s-sorry! Please!»
Katsuki's panting hard, adrenaline coursing through his veins as he stares wildly at the Alpha below him. Yes, that's how it should be, he thinks, a sharp grin slashing across his mouth, menacing and cruel. «Present,» he orders.
«You want me to snap your pathetic neck, slave?»
Deku gasps, shaking and trying to twist around to look at Katsuki. «No, no! Please, I'm sorry!»
«Then Present-» Katsuki pulls on the leash, the collar tightening- «Alpha.» There's clear mocking in his tone as he weaves his free hand into the soft, green fur of the plug stuffed in Deku's ass.
The boy's momentary silence is interrupted by his struggle to breathe. «Y… yes, Master...» he says at last, knowing he doesn't really have another choice.
Katsuki relents his hold and raises on his knees to allow Deku to move into position. He keeps his stare fixed on his personal pet; he privately admires the sensual curve of Deku's spine, his chest down and face buried amidst the bedding smelling of Omega in Heat, his ass in the air with his fake tail quivering and hanging between his legs.
Katsuki licks his lips, pleased at the sight.
He takes the plug out of the boy's hole, humming at how puffy and used it looks already, ready to be pounded by an Omega's cock. Katsuki curls his hand around his own rock hard one, strokes himself slow, dips down to his gushing cunt to gather liberal amounts of slick with which he lubricates the length.
«Say it,» he growls low, cock teasingly circling Deku's asshole and smearing fluids over it.
Deku sniffles into the furs. «Mas… Master, pl-please… fu-fuck me…!»
«Please, Mast-Master! Please, please fuck me!» Deku pleads, voice nasal and muffled.
«Mmh, that's better. There's my baby bitch,» Katsuki laughs.
He doesn't give Deku a chance to utter anything else. Katsuki's rearing his hips back and mounting the boy immediately after; he slams into Deku's hole with no care about tenderness or preparation, only the wetness from his slick and precum and the stretch provided by the plug prevent either of their flesh to tear and bleed. Deku screams anyway, fists clutching the bed but staying put nonetheless — as per his training —. Katsuki's cock rams in and out of the Alpha slave's hole in harsh snapping of hips and nails digging into scarred skin. He hovers over Deku's arched body; his strong scent of burned sugar overshadows the peppermint-musk, his weight keeps Deku firmly into position.
Katsuki mutters degrading insults and mocking sweet nothings into Deku's blushing ears, voice gravelly and rough.
«How d'ya like it… being fucked by an Omega, huh?» he says, teeth skimming Deku's nape just below the collar. «I'll breed ya— nggh!— why don't ya give me pups mh? You're my dog after all…!»
«Please! Aaah!» Deku mewls and cries. «No I— I can't, I— gghaah!— Mas-Master…! Please!» Tries to shake his head, to say he can't be impregnated since he's an Alpha, yet he rocks back onto Katsuki's length with as much vigor and need as Katsuki while he fucks into him.
«Gonna... fill you up Deku! Fuck, fuck—» Katsuki straightens up to grip Deku's sides in a vice, hips smacking loud and wet at a quicker pace, getting closer to release. «Fuuuck! Nnngh!!» His cock throbs as he empties inside the boy's ass; his pussy clenches on nothing.
Deku weeps and moans into the bedding, his whole body wrecked with tremors. Katsuki knows how desperate he must be, how miserable. He pulls out of the boy after regaining his breath — no knot to worry about, after all —, toying with the cum oozing out of Deku's hole, pushing in back in with his fingers. He grins darkly, locating the Alpha's sweet spot and tormenting it with the pads of his fore- and middle fingers.
He laughs when Deku wails.
Shifting on the bed, Katsuki gets off of the boy to kick him on his back and sit on his trembling thighs. He looks down at the slobbering, messy, flushed face; eyes puffy, teary and red-rimmed; scarred hands grasping at his decorated collar. He looks down at the dangerously engorged cock, he raises an eyebrow at the dark color.
«D'you wanna cum, Deku? Mmh?» he taunts. «I know it hurts… doesn't it?»
Deku nods furiously, so wrung out he can't even form proper words. «… -ease! I beg… y-you Mas'er…! Pl… se… plea… se!»
Katsuki pretends to consider it, shuffling forward until he's rubbing his obscenely dripping pussy over Deku's cock, teasing his clit and his hole with the leaking tip. The Alpha below him screams a broken sob, his hips futilely thrusting upward.
«Please! Ple...ase…! Oh, I— I'm begging, ple-please!! Master…! Lemme c-cum!! Pleasepleaseplease!!»
«You beg so nicely, Deku,» Katsuki praises at last, a light caress over the boy's bitten-raw lips and warm, freckled cheek.
Still hovering over Deku's length, he reaches backward, fingers brushing the magic-infused lock of the leather band at the base. He channels a tiny amount of power into it at the same time as he lowers himself onto Deku's cock.
A load of cum is immediately released inside Katsuki along with an animalistic howl, Deku's eyes rolling back into his skull.
Katsuki moans, undeterred by the feeling of cum escaping. He bounces and grinds on Deku's length, still rock hard and shooting rope after rope of seed inside him. The young Alpha's knot is swollen, taunting Katsuki's rim; as always, some part of him refuses to let it in, to let it seal them together.
«Shit! Shit, fu-fuck…!» he curses, too hot, too turned on and too far along in his cycle for this bullshit. «Aah, damn it!»
Katsuki scrambles to yank Deku up to a sitting position using the chain. He pops the collar open, letting it fall between their bodies; his eyes fall to the claiming bites on Deku's glands. Mark. Mark him again. He's yours. He sinks down fully on the knot at the same time as his teeth pierce Deku's right gland, tasting blood and smelling a fresh wave of peppermint-musk.
They both groan and whine, finally locked together as one after days of mutual torture. The unbearable fever inside Katsuki quells, even as his cunt is pumped full of cum.
Katsuki thinks he wouldn't even mind if he got pregnant this time.
