Chapter Text
Shouto was hungry.
He tread quietly along the forest paths, avoiding the drifts of fallen leaves as much as he could. The sky was grey, threatening rain; more storms, more bad luck. A storm was what had gotten him into his current mess; separated from his pack, and unable to get back while the river was swollen with floodwater and worse seemed imminent. Only a fool would tempt fate at this point; not only was the river impassable, but the mountainside was prone to mudslides in the wet, and travel in general was dangerous. The only reason he’d left the small cave he’d found to hopefully wait the worst of the weather out was because his hunger had finally grown too strong to ignore.
For all the good his efforts had brought him.
His stomach panged, and he resisted the urge to whine. The pack had moved lower down the mountain than usual this year, searching farther out for suitable mates now that spring was upon them and rut season was starting. His father was growing more and more impatient for Shouto to mate; a sentiment he actually shared, though not for the same reasons. Spending mating season alone had been a growing trial ever since he got old enough to start rutting. He would’ve been more than happy to fuck whatever omega in the pack would like to have him, and he didn’t think he was being vain when he thought there was more than one who would. Bucking desperately into his hand was a poor substitute for the warm, pliant body of an omega, and every season his teeth ached with the urge to sink into soft flesh and mark someone up, knot them and fuck them again and again until they smelled more of him than themselves.
But his father wouldn’t hear of it. No, no, only the best of the best for his son, his chosen heir; and fear of accidental pregnancies and a litter with the wrong dam meant Shouto had spent every rut he’d had with a watch on his cave, making sure he didn’t sneak off and do something his father didn’t want. Even though bitterberry tea was more than effective for killing pregnancies, and everyone knew it. Shouto was frustrated enough this season that he’d actually not complained when his father announced they were heading further out than normal, casting a wider net for mates. He’d hoped the new territory they had to travel would give him a chance to slip away, find his own omega on his own time; and he’d been right, at least in part. Escape he had; but now he was stuck, and hadn’t smelled even a trace of omega the day and a half he’d been here, stuck on this side of the river.
He sighed, coming to a stop. His stomach made a small noise of complaint.
Maybe things would be better on a full stomach; he had to hope so. He’d only managed to kill a few birds and a vole so far, and it wasn’t enough. He wasn’t starved, but he wasn’t used to going without either, and he'd always found hunger hard to ignore. Unfortunately, hunting this far down the mountain in this weather was damnably hard, especially for a shifter like him. His white fur and dark red stripes did alright in the snowy peaks of the mountaintop; down here, in the green and grey and wet, he stuck out like a sore thumb. Apex predator or not, he might as well shift to his secondary form for all the good his first was doing him. At least as a human he’d be smaller, perhaps quieter. His tiger paws were soft with fur meant to dull noise, but that didn’t help a lot when all the ground was damp, and clung to each step with slick sounds.
There was a rustle in the trees. He froze immediately, muscles tensing, ears flicking up.
There was a long moment of silence.
Another rustle. Another— there!
Shouto spotted movement in the bushes ahead, to his right, and sprang.
There was a sudden cacophony of noise as a small shape burst from the underbrush, and Shouto hit the ground just behind it as it leapt through the air and landed hard in a flurry of leaves before scrabbling for grip and racing forward. Shouto didn’t let himself pause, racing right after, determined not to let his prey escape. The creature was fast, lightning quick, but Shouto was much, much bigger, and he let his long legs stretch and eat up the ground in two quick bounds before taking a chance and pouncing again, coiling and springing in the span of a second.
He landed on top of his prey, front paws slamming it to the earth, and felt a triumphant snarl rip from his lips as they skidded a few feet in the wet earth, leaving a furrow behind. He flexed his grip on the small, shaking form, near vibrating it was breathing so quick, and extended his claws to make sure it stayed pinned, letting another snarl loose. It shook harder, and as Shouto got his breath back he levered himself over his catch, sinking it into the wet earth as he finally got a good look.
It was a rabbit; a soft, fluffy bunny with dark fur. Its long ears were plastered flat to its skull in terror, and it stared up at Shouto with huge dark eyes, the whites showing as its gaze darted about as if to look for an escape, before inevitably returning to him, shaking and scared. Shouto felt his lips curl back from his teeth with a low growl of triumph, feeling the rush of a successful hunt as he panted, tongue lolling loose and starting to drip saliva. Fuck, he was hungry.
He bent to envelope the tiny creature’s head in his jaws and crush its skull, put it out of its misery so he could enjoy his meal. His mouth opened wide.
There was a strange, strangled noise from beneath him, and then suddenly the shape under his paws…twisted.
He yanked back in surprise, only just managing to keep his grip as the rabbit’s form blurred then changed, shifting under him in a rapid series of contortions and growth. Fur melted away to reveal pink flesh and simple clothes of rough cloth, and Shouto looked up from the expanse of newly-bared skin with incredulity to see those same, big dark eyes still staring at him, still wide with terror, but now set in a round, freckled face capped with dark curls.
Shouto’s ears lowered to his skull, and a low growl rumbled from his chest again. Fuck…another shifter.
Ugh. Great.
Eating other shifters wasn’t something Shouto made a habit of— he didn’t much enjoy the pleading, and besides, he hardly had much of a chance to anyway. Prey shifters were usually smart enough to avoid predators like him, unlike simple animals. But they all lived in the same world, knew the same rules. If this boy thought he’d be getting mercy just because he’d shifted to a form with more meat, he was sorely mistaken.
He lowered his head again, opened his jaw wide.
“W-wait— !”
A panicked, high-pitched voice sounded from beneath him, and Shouto set himself to ignore it, saliva filling his mouth again as he drew near enough to taste the boy’s scent on his tongue. Oh, god, that tasted good…warm and sweet, even with this faint a taste. He couldn’t wait to eat more.
“P-please— !”
There came a high-pitched whine, and Shouto froze.
His top teeth brushed the curls atop the boy’s head, his bottom the soft skin of his chin. Drool dripped freely onto the shifter’s face, trapped in Shouto’s maw, now frozen on the very verge of biting. But that whine— it had triggered something, a shiver that went right down Shouto’s spine. In the span of a second, his hunger was suddenly doing battle with another instinct, just as strong.
There was a whimper from beneath him, this time, and his fur bristled as suddenly his teeth started to ache and his gums started to itch for a whole different reason. Then the boy’s scent ballooned underneath him, all at once; a wave of warm, golden sweetness wafting right into his mouth, suffusing the very air, sliding down his throat.
He pulled back as arousal suddenly burst to life in his veins, fierce and demanding, and stared down. Under his paws, the boy looked back, but this time with his head turned to the side, baring the long column of his throat. Shouto’s eyes shot to it as if pulled, and he swallowed heavily, feeling his body start to heat and his cock start to stiffen. Oh, shit—
This was an omega.
“Please,” the boy said again, voice rough and cracking, but Shouto’s attention was drawn more to how he tilted his head back even more, then shifted a little under Shouto’s weight…and spread his legs. Shouto felt a wave of sudden arousal pulse from him in a burst of his own scent, unintended. He could see when it hit the boy under him, saw his eyes widen and his cheeks pale, even as the pulse in the soft crook of his jaw quickened. Shouto could see it fluttering, could almost hear its soft thmp-thmp-thmp. He wanted to place his mouth over this small thing’s neck and squeeze until it raced even faster; then find the soft glands right by that pulse and lick and suck and worry at it until the omega was whining and gasping and pleading for him to stop, scent thick enough to choke on.
His cock ached. He could feel it starting to slip from its sheath, even feel the heavy weight at its base of his knot starting form, already. Fuck, he was hard up, wasn’t he. For a prey animal, no less— but he couldn’t help it, this was precisely what he’d left for. A sweet little omega who’d spread their legs for him and let him do what he wanted for once, instead of having to hold back like he’d had to all these years. God, he had so much he wanted to do.
He let out a long breath between his teeth, almost a hiss, watching the boy regard him with barely concealed terror as he trembled beneath him and put his all into appearing submissive, alluring. It was working.
Shouto bent his head down again, but this time, shifted as he did it.
By the time he’d bent low enough to reach the boy’s neck, he was fully human; and he could hear the omega’s breath hitch as he brushed his nose against the soft underside of his jaw, felt that frightened, fluttering pulse…and then breathed deep.
That warm, buttery scent filled his sense again, stronger than ever before; and he moaned, low and guttural, cock hard in his pants. He slid one of the hands pinning the boy down up to curl around his neck instead, sharpening his nails into claws as he did so to gently prick against this bunny’s skin, let him know that just because Shouto was smaller now, that didn’t make him any less a predator. If this rabbit thought he could get Shouto’s guard down only to sprint off as soon as he could, he had another thing coming; this was the first omega Shouto’d ever been allowed to be near so close to his rut, and he wasn’t going to let him go.
The boy’s pulse quickened as Shouto’s hand gently but firmly closed around his throat, covering nearly all of it, and he felt sure he got the message. Even in human form, Shouto was almost twice his size. He wondered if that meant he’d feel even tighter around his cock.
Shouto bit his lip on a short moan…and then smiled, slow and sharp and almost disbelieving as his arousal spiked. Who would've thought— just when he'd given up, an omega nearly runs straight into jaws. This day was looking up.
The omega shivered as Shouto’s pheromones hit him, thick and smoky and heavy, and Shouto relished how it felt, that small, trembling motion under soft skin. Slowly, he brushed his lips over where he thought the omega’s scent glands might be; they weren’t visibly different from regular skin, but they ought to be near his pulse. He knew he’d found it when the omega not only shivered, but startled like he’d been shocked. Shouto grinned, and opened his mouth.
“Ah— ah— !”
The omega’s cries were startled and high-pitched as Shouto carefully started licking and nipping at his gland, mindful of his sharp teeth on such a sensitive area, but unable to resist worrying it harder and harder as the omega’s scent thickened and his noises grew louder and longer the more Shouto did. Heat swelled in Shouto’s veins and fogged his head until he felt this omega was all he could hear, all he wanted to hear; and he wanted more.
He closed his mouth around the gland and sucked, hard.
“Ahh— !”
Small hands shot up to his shoulders and Shouto found himself startled enough that he actually got pushed back a little, before regaining himself enough to retaliate with his much more considerable weight, tightening his grip around the omega’s neck with a growl. The omega gasped, but stopped pushing, and Shouto found himself looking down at a face much more flushed than it’d been before, the little bunny’s chest rising and falling rapidly even as his hands stayed on Shouto’s shoulders, a futile pressure. Two long rabbit ears had even popped out from those dark curls, and were plastered back against his skull— he must really be having trouble staying in control.
Shouto narrowed his eyes, slowly cocked his head, and then started to lower himself again.
“W-wait— alpha, please— ”
He paused.
Alpha. Oh…no one had ever called him that before. At least, not like that— with a voice that shook and begged permission in every tone. He felt something dark and pleased curl inside him. Huh…he liked it when this omega begged.
“C-can we…uh…”
And then the omega said something in a language Shouto didn’t understand. He cocked his head again, this time frowning slightly. Ah, dammit…was this shifter from the lowlands? Hm. Maybe that was why he looked so soft. Still though, mildly inconvenient—their languages were similar, but not the same. The omega had been using mountain speak, but he seemed to have a hit a roadblock now, stammering at the clearly uncomprehending look on Shouto’s face and fumbling his words.
“Like— uh— ”
Shouto felt what little patience he had dissolve, and started to bend low again, wanting another taste. Whatever this bunny wanted to say, it was of little import anyway. He was Shouto’s now, and he wasn’t letting him go until he was satisfied. And words hardly mattered for what he wanted to do.
The bunny squeaked and pressed at his shoulders again, but this time Shouto persisted and easily kept going, the little omega’s struggles barely anything compared to fights he’d had with alphas in his pack. If anything, it made him even more excited; and he felt his cock throb as he let out a low growl and licked a line across his prey’s throat, above where his hand still lay, before opening his mouth and fitting his teeth to the curve of it, gentle but sharp. The omega stopped struggling then, scent souring a little in fear, and Shouto let out a pleased rumble. Yes, good— submit. Arousal spiked.
“Turn over,” he rasped, as he carefully drew back again, hand flexing on his omega’s throat a little just to feel how delicate it was, how soft. He licked his lips, eyeing that smooth skin, ignoring the look on the omega’s face. God, how he wanted to be in this omega. The urge to sink his teeth into that tempting throat and tear it open was almost as strong as the urge to flip him over and push inside, into tight, sweet heat— but he knew which to listen to. Prey he could find again; an omega while they were both alone, not so much.
“A-alpha,” the omega said, and Shouto flicked his eyes back up to his face to find it drawn with fear, fear the omega was clearly trying to get a hold on. Shouto lazily tested his tongue against the sharp point of one of his canines, watching the omega’s eyes immediately follow the movement, and felt an amused curl of pleasure simmer to life in his gut at the panic in his face. This little prey animal was clearly trying to get out of what he’d started; and Shouto wasn’t going to let him.
“Another…place?” the omega tried, clearly still trying to find the words, gaze darting back to Shouto’s even as those long ears of his betrayed his fear. Still, Shouto liked them back like that— it showed his subservience. Another swell of scent wafted up, sweet and thick…but not quite as thick as before, and Shouto narrowed his eyes. This omega was trying to pull something. “Need…nest.”
Shouto considered this for a second. The bunny wanted a nest, hm?
As if. This rabbit was just trying to distract him long enough to make a break for it.
He bared his teeth, growled, and watched with satisfaction as the omega startled and shrank back, eyes wide. He pumped his scent out harder, focusing on making it strong, indomitable. The omega curled beneath him as much as it could, averting its eyes, and Shouto felt hot satisfaction in his belly.
“Turn over. Now,” he said again, putting some threat into his words this time and expecting the omega to catch it. Happily, it seemed he did.
The bunny kept his eyes averted but got his arms under him, and Shouto let him get himself up enough to flip over, keeping a hand over his throat the whole while. When he was flat on his belly, Shouto finally let himself move as well, shifting up more between the rabbit’s legs before taking his free hand and grasping the bunny’s hip and lifting. The omega got the idea fast enough, keeping his shoulders down but lifting up on his knees, though he still trembled when Shouto pressed against his raised ass, cock hard and aching. He let out a low groan at the relief of even this little bit of pressure, and rolled his hips, curling over the little omega to keep the hand not clutching his hip pressed against the back of his neck, keeping him down. He was so small. Shouto felt a low, rumbling purr rise from his chest at his little thing’s obedience, at how good he looked like this, bent under Shouto with his slender neck trapped under Shouto’s broad palm. His round, freckled face was a pretty profile against the muddied leaves littering the ground, and Shouto let the hand on the back of his neck drift up a little, enough to brush against the line of his jaw, almost a caress. The boy shuddered, and a small sound, a whimper he’d tried to suppress but not quite managed, escaped his lips.
“You’re pretty,” Shouto allowed, seeing the tight breaths the omega was taking, smelling the fear now truly starting to roll off him in bitter waves. He had been doing an admirable job in suppressing it, presumably to try and lure Shouto into a false sense of security and then race off, but he’d clearly reached his limit. Shouto liked how he looked like this— but the scent he could do without. “I will let you go, after.”
The omega’s eyes finally flicked up to him from where they’d been avoiding his stare. Shouto looked into those big, dark depths and felt a twinge of something…different, in his chest, something uncomfortable that he quickly suppressed.
“Y-you…you promise?”
Shouto nodded. After his rut, this boy could go wherever; he really didn’t think he’d care at that point, having gotten what he wanted. Maybe the little thing would break at some point during his rut, given how small he was, but that was neither here nor there. The boy stared at him for a long moment, as if trying to see if he was being honest, and Shouto let him look.
Finally, the bunny broke the stare to look down, pretty dark eyes hidden under pale lids and long lashes.
“Okay.”
Shouto felt a real purr rumble up from inside him, unbidden but impossible to stop, and on a whim leaned down enough to rub a little against the bunny’s hair, spreading his scent into the curls. He felt the omega shiver again, felt a pulse of arousal as this new position pressed him even tighter to the bunny’s ass, but ignored both for the moment in favour of letting his happiness out. His first omega— fucking finally. He couldn’t help but be excited.
He leant back and pulled the bunny’s pants down.
This time he could see the shiver ripple across the rabbit’s skin, goosebumps prickling in the chill air. But Shouto didn’t feel the damp anymore, barely noticed the grey, cloudy sky above; he could feel his body’s temperature rising, his gums aching more and more, his hands growing hot. His rut was starting.
Keeping one hand clasped to the bunny’s hip — claws extended and pricking warningly against soft skin, making the omega start and yelp — he shuffled back enough to yank the boy’s pants off the rest of the way, forcing the omega to comply. Coming back, he slid a hand up the omega’s spine, under his shirt, pushing it all the way up to his shoulders and baring beautiful tan skin. A few dark freckles dotted along his shoulder blades, but Shouto hardly noticed, too preoccupied with shimmying his own pants down enough to free his cock, achingly hard. He pressed against the omega’s ass as soon as he could, just the drawstrings of his pants opened and hastily shoved down a little, and groaned with relief as he slid between his omega’s cheeks, feeling the soft warmth of his skin. He heard a small sound from below, another cut-off whimper.
He ran his free hand up the omega’s thigh, and only thought to soften the grip of the other around the omega’s hip when he realized his claws had started to dig too deep, and little trickles of red were starting to drip down the omega’s leg. The omega was shaking constantly, now; little shivers running up and down his body. Shouto retracted his claws fully, but still ran his hands up the omega’s thighs, hips…and then his ass, feeling his breath catch as he was able to grab handfuls of soft flesh and squeeze. Fuck, he’d had fantasies like this.
There was a choked sound from below, but Shouto was leant back and focusing fully on the beautiful sight in front of him: a presenting omega, not whatever face the little bunny was making down in the dirt. He gripped round flesh again and spread the omega’s ass, revealing a soft pink pucker and, further below, dark curls. Both glistened slightly, he was pleased to see; wet, though not by a lot. Still, that made that dark, possessive feeling inside him purr. Like it or not, this omega was affected by his scent; and he better hope he gets wetter, soon, because Shouto wasn’t stopping.
To that end, he slid his hands up from the omega’s hips and up his bared sides as he drew closer again, pressed himself against him. Bending over the little bunny, he saw his hands were big enough to splay across most of his back even curled around his sides, and he squeezed them a little, pleased, feeling the delicate arcs of his omega’s ribs even as he slid his cock back against the omega’s center and bucked a little, feeling that slight damp. The omega made a sound, and Shouto finally looked to his face. His cheeks were wet with a few shining teartracks, his lips trembling— but his gaze was still respectfully lowered, fixed on the ground.
Acting on some instinct Shouto hadn’t known he’d had, he bent down and nuzzled the omega beneath his jaw, letting out a small, comforting rumble. He felt the omega’s throat work as he swallowed, and turned a little to drag his lips over his gland again, seeking that sweet scent from before. It’d turned almost entirely dull, and he set to work coaxing it back to life with teeth and tongue. He knew he’d succeeded when the omega’s shivering calmed a little…only to then return full force with a tremor he could feel run right down the boy’s spine when Shouto sucked hard at sensitive skin.
A high-pitched whine sounded — muffled, but there — and Shouto rumbled again and sucked harder, hands starting to smooth up and down the omega’s sides. When he felt a sudden gush of slick against his cock, he rumbled harder, pleased, mouth slipping into a grin. He let his scent grow, making sure it was thick with arousal and approval, and felt the boy get wetter.
“Just— stop, just— ” he heard the omega gasp quietly, and he lifted himself up enough to see his face. Fresh tears were slipping down the boy’s cheeks, and he actually managed to move his gaze up to Shouto for a moment, eyelashes damp.
“Why are you— just do it and then leave, p-please.”
Shouto’s head tilted to the side a little, automatic, as slight confusion took him. Stop? Leave? He wasn’t going to do either of those things.
“No,” he said simply, and bent back down to start worrying the gland at the base of the boy’s neck this time, at the crook of his shoulder. It was less sensitive than the ones near the jaw, but he didn’t want to overwork them. He licked a broad stripe across his new target, and grinned when the boy shivered again, his scent blooming.
“Just…please, hurry up,” the boy said again, voice wet and choked. “Why are you…bothering to…”
Words seemed to fail him. Perhaps he didn't know the right ones. Shouto gave a hard suck to his gland, heard him yelp, then mewl, with a sense of satisfaction. He lifted his head.
“I like your scent. And this will go better if you’re wet.”
The boy actually had the audacity to glare at him, even if it was very brief, an angry sideways glance from where he seemed to be turning his face into the leaves, trying to hide. “Why do you care about that.”
Shouto squinted at him, unsure of how to go about explaining something so rudimentary.
“I just do.”
The boy opened his mouth again, but Shouto was done with this conversation; he wasn’t here to talk, anyway. The omega was much wetter now, he could feel it, and his scent near back to sweetness. He should spend some more time, probably, getting him ready; but he was impatient, and this boy was starting to test him. He wanted him to hurry up? Fine, then he would. That was no problem for Shouto— the desire to sink into this little body and fuck it hard was growing almost overwhelming.
He let his scent grow again, now so thick in the air about them that he was truly grateful he was probably bigger than anything else in this forest save a bear, and didn’t have to fear interruptions. The bunny flinched beneath him as he let his pheromones strengthen, but he was pleased to feel another gush of slick against his cock anyways, even as the bunny trembled beneath his hands. He drew both back to the omega’s ass, and pressed a thumb to one round cheek to palm it open.
Pink, flushed, wet skin met his gaze, along with a burst of rich, mouth-watering scent. He felt his teeth lengthen and the base of his cock ache, drool gathering in his mouth. Fuck, fuck, yeah— this was it— what he’d dreamed of since his first rut, bucking into his fist and wishing it were warmer, wetter, tighter.
He licked his lips and swallowed hard, almost unsure of where to start. Which hole did he want to fuck first, cunt or ass? He’d fuck both, certainly, in time. The omega’s mouth too, if he could make sure he wouldn’t bite. He had years of frustrations to work out, and only one omega to do it with; this little bunny was just going to have to deal. Or break; but either way, Shouto would be getting what he wanted. He’d take him back to the cave after this, his temporary hideaway, and fuck for as long as his rut lasted. And if the bunny tried to run before it was done, before their deal was up, he’d catch him and fuck him still, but eat him at the end of it. Why keep a deal the other had broken, after all.
But that was a nebulous future, distant and unimportant. Right now he had an omega bent under his hands, legs parted, ready for his knot, wherever he wanted to put it. Shouto licked his lips, made up his mind, and pressed his cock to the omega’s tight, ready cunt. His hands held the omega open as he started to sink in.
He had to suck in a breath at the very same time as the omega cried out, sharp and shocked and in pain. Holy fuck, he was tight— even tighter than Shouto had thought he might be. He was only an inch in and he had to stop, both because his cock felt like it was caught in a vice, and because the omega had started to move under his grip, squalling and trying to pull away.
“No, no— fuck, it hurts, take it out take it out— !”
Shouto gripped the bunny's hips with renewed strength, letting his claws pop back out, and the omega cried out as they pierced skin. He stopped struggling for fear of his hips getting shredded, but shook with sobs.
“Alpha— please— it hurts, please, please stop—”
“Thought you said you wanted me to hurry up?” Shouto couldn’t help but shoot back, even as he gritted his teeth and tried to decide if he really did want to pull out or not. The omega felt almost too tight to keep going…but also, the longer he stayed, the better it felt.
“I was wrong, please, please alpha I’ll do anything else, I didn’t realize— I’ve never, I’ve never taken a knot before, I— ”
Shouto froze, that possessive thing inside him suddenly sitting up straight.
“You’ve never…been with an alpha?”
“I’ve never been with a-anyone, please…” the omega sobbed. “Please, I just, I didn’t want to die— there must be something else I can give you, please…”
Shouto’s hands tightened on the omega’s hips, unthinking— then loosened quickly when the omega cried out again, sharp and in pain.
He stared down at the little form beneath him, the slender hips. He tilted them up a little, ignoring the omega’s hitching sobs, and moved a hand to the boy's cunt to pull back wet, swollen lips. The omega let out a high-pitched, broken sound as Shouto stared at where his cock entered the boy’s body. The omega's hole was stretched tight around him, looking almost strained, flushed red where it wasn’t hidden by short, dark curls. He was so much smaller, Shouto looked almost comically big entering him. And he’d be the first to do so; the first to stuff his cock into this tiny body, the first to knot it. If he could even fit his knot.
Hunger roared to life in Shouto’s belly. This little body was all his; he’d stretch it open to fit him and only him, leave this boy forever remembering his first. Shouto almost wanted to break him open so no one else could use him; split him in half on his knot, then bite him so people would see the scars and not even want to try. What could prey shifters possibly have on Shouto anyway? He was bigger, stronger, better. Maybe this little omega would even return to Shouto, one day, realizing no one else could fuck him like he could. Maybe he’d ruin him for anyone else.
A low snarl slipped from his lips, and he gripped the omega’s hips hard and pressed forward.
“No, NO— !”
The bunny struggled wildly underneath him as Shouto sank into him slowly, inch by inch, and he growled even as he held the little brat still, forced himself into that clenching warmth that seemed to be trying to push him out with every movement. He was wet, he could feel it, but that didn’t seem to be enough as Shouto made this omega give to him even as he cried and screamed, clawing at the earth as he tried to get away. Shouto bit his lip hard, watching himself disappear into this little body, feeling that vice-like heat grip his cock and relishing every moment.
When he finally, finally bottomed out, he yanked the omega flush to his hips, ignoring the cry of anguish that came when he did, and bent over him, dipping down to his neck. For a moment, he just panted, hot air gusting over the omega’s sweaty nape as he tried to adjust to this intense feeling, fought the urge to move and fuck this omega into the ground. The bunny lay there, shaking, loud sobs wracking his body. Too loud— before anything else, this brat needed to be taught a lesson.
“Don’t fight,” Shouto growled roughly against the omega’s neck, and bit down, right over his nape.
There was a high, cut-off sound, almost a shout, stopping mid-way as Shouto felt the omega tense all over…then fall limp.
Shouto removed his teeth, and eyed the mark on the back of the omega’s neck with satisfaction. Blood welled up, and he bent again to lick it up, relishing the taste. His omega barely even reacted; and when he pulled back again, he saw the bunny lying limp against the ground, eyes wide and staring into the distance, tears spilling slowly down his cheeks. He bent again and licked a few up.
“Good boy,” he said, and pulled back to fuck him hard.
Ah, ah— now this, this! This was what Shouto had wanted.
The omega was prone beneath him, hips held up solely by Shouto’s hands, but he didn’t mind. His forced paralysis wouldn’t last long, but hopefully would be long enough for Shouto to fuck him into proper submission. He had to bite his lip as he held the bunny firm and fucked into that warm, wet hole, pants and groans escaping him with just how good it felt. Fuck, he was gonna knot soon, too soon— but he supposed it didn’t matter. They had more than just today, after all, and right now he couldn’t hold back, couldn’t help but grip his omega’s hips tighter and tighter as the tension grew, forced him open with every thrust, even as that tight hole of his tried to keep him out. He’d fill him up, knot him good, then fuck his other hole; and by the time Shouto was done, he’d be able to slip into him no problem, his body carved open to his needs.
A muscle in the bunny’s thigh twitched, and something inside him tensed; Shouto held him harder, forced him back onto him and rammed past it. A pained, broken sound escaped the rabbit’s lips, though he still couldn’t move; and Shouto started fucking him faster, harder, sharp slaps of flesh on flesh sounding through the area as he panted and moaned, teeth starting to ache again as his knot started to swell. A muscle in the bunny’s leg twitched again, and Shouto saw his head move a bit from as he started to curl over the omega’s form, pleasure building and sparking inside his gut.
“Please…” came a small voice, and Shouto watched as the omega tried to get himself together, fingers beginning to twitch and curl, face starting to move with expression again. “Please, don’t…”
Shouto opened his mouth to answer— but found he couldn’t, a low, rough sound escaping instead as he felt his knot form and start hitting the omega’s wet, open entrance with every movement, too big to just slip in. He gripped the bunny harder and forgot all about talking, bending further over that small body, mind funneling down to one need, overwhelmed with the urge to fucking knot, to be surrounded by that sweet heat and fill this tight, tight hole full to bursting—
Fear struggled onto the bunny’s face again, slow as it regained its functionality, but there. He stared desperately up at Shouto, big eyes dark and pleading as they filled with tears.
“Please, it’s, it’s too big…p-please, just pull out…”
Shouto breathed harshly above him and, with a burst of strength, yanked the omega back onto him as he thrust forward harder than ever before.
His knot sank inside, finally, and a jagged growl ripped from his lips even as he felt the omega scream, high and loud, in pain. His hole constricted around him, tight walls convulsing around his knot, spasming, but Shouto didn’t care. With a long, low moan, he bent back, face to the sky, and came hard.
Pleasure burst through every vein as he felt himself release, whole body tensing as he came, and came, and came, emptying himself into the body beneath him with another groan of pleasure. It was intense, so fucking intense, everything he’d ever dreamed of; he could barely feel the omega’s hips beneath his hands anymore, just that wonderful sensation of releasing into a pliant, helpless body, locked onto his knot and unable to move. He felt every nerve in his body light up like wildfire, then slowly, slowly, burn back down, ‘til he was empty and shaking with relief.
With a long, trembling exhale, nearly lightheaded with bliss, he finally looked back down, almost feeling like he was coming back to earth. Below him, he saw the omega had wrapped his arms around his head, trying to hide his face, and was crying into the crook of his elbow with deep, full-body sobs. He was quiet, though, trying to bite back his sounds. Shouto supposed he could forgive that; and besides, he was starting to like how this pretty boy looked with tears on his face, dotting his lashes.
As if sensing his stare, the boy peeked up and, seeing him looking, immediately looked back down and hid his face back under an arm. Shouto grinned, amused, and bent low.
“Hey,” he said, nosing at the boy’s neck. He felt the omega shiver. “Pretty omega. How does it feel, taking my knot.”
Silence. Silence, save for a few hitching sobs. Todoroki nosed up under his jaw, brushed his lips over that warm skin.
“Tell you how I feel. Amazing, omega. You feel amazing.” Shouto moved a little, then groaned when that coaxed more cum from him, knot aching pleasurably. The omega’s breath hitched and he curled further into his arms, breathing uneven. Shouto moaned into the omega’s neck, eyes sliding shut, and worked his hips again, wanting more of that feeling. He came a little more, felt the omega twitch around him. Fuck, that felt good. Maybe he could keep fucking this guy, right up until his knot went down. And then he could set about getting his other hole good and ready.
“I’m gonna fill you up,” he murmured against his omega’s neck, flicking his tongue out, tasting the skin. It tasted of sweat, salt. Fear, pain. Shouto could grow used to that, he supposed, if it was what went with such pleasure. Maybe he could even grow used to that bitter, scared scent he could sense traces of underneath the heavy smell of sex and Shouto's own, overwhelming scent.
Then the realization that he could, indeed, barely smell the omega really hit him— and his eyes shot open as an amazed smile tugged at his lips.
Finally, finally he knew what it felt like to cover an omega in his scent, inside and out!
A purr, unbidden, rumbled from his chest, and he nuzzled harder into his omega's neck. He moved his hips again, the little he could, grinding against his omega and purring louder when his knot throbbed pleasantly and he came a little more. He moaned happily. The omega let out a choked sob.
“Oh, I am gonna knot you so many ways, little bunny," he murmured, giving a little nip to the skin by his mouth. "Fill you up so good.”
That made the omega raise his head, wet face suddenly popping out from his arms and forcing Shouto back as he moved. The alpha looked down to see the omega staring, eyes wide and horrified.
“Wh— no, you said! You said you’d let me go!”
“After my rut, yes,” Shouto said, and watched as the boy’s eyes grew even wider. Wow, that was— he hadn’t thought they could actually get any bigger. “You’ll be free to go then, to wherever you like.”
The boy stared at him, face turning bleach white.
“N…no, you said, y-you said I could go,” he said, stuttering, but finally finding his voice. “You said I could go after— ”
The bunny paused, and Shouto watched him realize Shouto hadn’t actually said after what. The look of horror grew, and his eyes shot back to Shouto to look at him pleadingly.
Shouto felt a pleased feeling coil in his belly. Yes, he liked it when this guy begged.
“Please…please, alpha, I can’t…I won’t survive it, please.”
Shouto considered this, and the fact that it was indeed a real possibility. His knot ached. He moved his hips a little, almost absentmindedly humping against his omega, and this time could watch him flinch as Shouto released more cum into him with a little sigh of pleasure. He bit his lip after, feeling that pleasant echo of release.
Let this go? The best thing he's ever had?
“No. A deal’s a deal. Whether you survive or not is up to you.”
He watched the boy’s face crease with panic and despair just before he lowered his head to that slender neck again, felt that fluttering pulse. The buttery scent from before was long gone, but he remembered it, and wondered if he could make it come back. He’d miss it, when this omega was gone. He’d miss this omega, period. He sighed against the omega’s damp skin, suddenly regretting giving his word.
Then a thought occurred to him, and he perked back up.
He’d promised to let the omega go. But he’d never promised not to hunt him down again, after.
He grinned, teeth sharp. The omega’s heartbeat thrummed rabbit-quick under smooth, tan skin.
“I hope you do though. I really hope you do.”
