Hizashi lets out a curse as his boot clad feet catch on yet another protruding root, almost sending him tumbling into the dewy grass of the jungle floor. Frustrated and tired, he decides to stop for a short break under the shade of a tree, swatting at the mosquitoes and bugs buzzing around him, taking off his hat to futilely fan himself in the heat while eyeing the map he brought along with him, trying to decipher where the hell he is.

It's of course useless, since there's nothing but trees and grass in any and every direction he turns in.

All he wanted was to find the cave rumored to hold ancient treasures and artifacts, and finally get the respect he deserves, but no! He just had to get lost in the middle of the jungle, where no one even knows he is, because he wanted to be dramatic and mysterious and have no one else try to take this discovery away from him!

Letting out an exasperated huff, he scrunches up the useless map and shoves it down his satchel.

Feeling thirsty after all the wandering and stumbling, he pulls out his bottle of water, only to realize that there's not much left. Drinking half of what might be a mouthful, he decides to go in search of more water.

He's pretty sure he hears running water in the distance, so he follows the sound of it, eventually breaching the treeline and stumbling upon a field of tall reeds that are his height. He can hear running water on the other side of it, so he moves forward.

Wading through the thick foliage of reed bushes, ground soft beneath his feet, he trips over something he can't see, steel toed boots colliding with the surprisingly soft exterior, before toppling over, arms pin wheeling comically as he yells in surprise.

The fall knocks the breath out of him a bit, and his glasses now sit crooked on his nose. Grumbling to himself he begins to stand back up, fixing his glasses to sit properly once again, only for him to freeze as he gets a good look at what he tripped over.

Because it's looking back at him.

Red, slitted eyes are locked onto him, and with heavy, practically jelly legs, his heartbeat pounding in his ears, and the colour drained from his face, he realizes exactly what he's faced with.

It's a man, but it's absolutely not.

A Naga.

He's heard stories of them of course, but he thought they were just that; stories. He didn't expect for the tales of the half-man half-snake the people of the village he'd passed through to be real. He didn't expect them to be warnings.

So of course he does the reasonable thing, and lets out a blood curdling scream in the face of what is surely to be his death.

The last thing Hizashi remembers is the sight of those piercing red eyes turning into hypnotic, pulsing swirls of red and black, glowing and bright, before everything turns dark as he loses consciousness.

*****

Shouta was having a decent day. He'd eaten a satisfying meal, found some useful items left behind by humans, most likely offerings from the village that his forest borders, and decided to take a nap in his usual reed bush on the riverside. It's big and tall enough to completely cover him when he's curled up, making it look like he's not there at all. It's perfectly damp and soft, while also being in a wonderful patch of sunbeam whenever he coils his tail around himself like a cocoon for his daily naps.

It helps that it's not far from his den, where he actually lives.

It's his usual routine of living in his jungle, days peaceful and pleasant.

And then he's awoken to the feeling of being kicked and the sound of something loud.

He looks to see a human, a man, hair like the sun, in the form of a golden waterfall, wide eyes the colour of the grass of beneath them, and when he sticks out his forked tongue to taste the air, he smells divine. Like a potential mate.

Shouta's eyes lock on to his target, refusing for there to even be a chance of him getting away.

And then the man screams. Loudly.

It disturbs some nearby birds from within the trees above as they flee in a shower of leaves and screeching chirps.

Almost instinctively, not wanting his eardrums to be bombarded with the loud level of the scream, he captures the noisy human in a trance, slithering out lazily when he falls silent, standing limp, wide-eyed and dazed.

The man's eyes are a pulsing swirl of green and red to almost match his own, pupils shrunken, and Shouta chuckles at the stupid, wide, dopey smile on his face. They always look so funny when he has them under his control like this, goofy really.

He hadn't taken a human in so long, growing tired of settling for the subpar options, but him. This human seems perfect; alluring and smelling even more so, and with the glimpses of memories he's gaining while the human is in his trance, seeing his life and the people around him, Shouta makes his decision to keep him.

With the tranced man coiled within his tail, he turns to go to the narrow entrance to the cave he calls his den, nestled into the side of a rocky hill a few feet away from the riverbank.

Settling into his bed of soft moss, dry leaves and a few blankets he'd s̶t̶o̶l̶e̶n̶ gotten, he stays coiled around his human, soon to be mate, and goes back to sleep.

*****

When Hizashi wakes up, slowly coming to his senses, it's with a headache and the distinct feeling that something is wrong.

He remembers he was trekking through the forest, and he's pretty sure he passed out or hit his head, because he also has the memory of seeing a half snake, half man, a Naga, but that has to have been a dream.

Right?

As his brain fog eases away, he finally manages to open his eyes, squinting while his eyes adjust to the low light.

In doing so, he freezes at what he sees, quickly realizing that it was infact not a dream, as there's the fucking Naga staring right at him from beside him, its tail coiled around him, restricting him, and Hizashi freezes, fear gripping his heart, only barely managing to not scream again, instead making some sort of choked, squeaking sound from the back of his throat.

The pounding of his heart and the sound of blood rushing through him is all he can process as the pure terror wracks through him.

Taking a moment to panic internally, he takes a deep breath, trying to calm himself lest this thing feeds on fear too.

On one hand, he's miraculously not dead. Great! On the other hand, that may change at any time. Not so great.

Taking another breath, he manages to calm down when he finally realizes something.

The Naga's breathing is slow and steady, without a single reaction or movement.

It's sleeping.

Fucking hell, it's sleeping, peacefully even! It just sleeps with its eyes open because it's a fucking snake and snakes don't blink because snakes don't have eyelids and holy fuck that's a snake!!

Eyeing the creature warily, he tries futilely to see if he can move at all, and of course he can't. Sighing shakily, he takes a look around what seems to be its den.

The space is warm and damp, with almost half of the area taken up by a pool of water, most likely from the river if they hadn't moved too far, and a fire burning low in a pile of coals, flames casting deep shadows and patches of dancing orange light around them.

There seems to be a pile of things a bit further from them, along with other things scattered here and there, but Hizashi can't see much else in the dim light, so all he can do is ignore it for now and hope that they're not the bones and carcasses of the Naga's victims, especially human ones.

With nothing better to do, and no way out, he decides to take a better look at his captor.

Even through the haze of fear-horror-despair that runs through him, he can't help but notice the stunning, haunting beauty of the creature.

Illuminated only by the low, flickering light of the fire, the glow of it dancing within ruby eyes and across obsidian scales, the Naga appears starker than before, somehow more luminous,

Its head is pillowed on its own tail, the length of it looped around both Hizashi and itself, almost like a sleeping bag.

Inky black hair falls in waves over its shoulders and forehead, and there's a light stubble along its jaw, but that's where the more human features seem to end. A smattering of black, shiny scales paint patterns on the corners of its forehead, down its temples to its cheekbones, framing crimson eyes, with the same dark scales covering the entirety of its neck and shoulders, down lean arms to the tips of its clawed fingers, and most likely its back, all along the long, thick tail coiled around them; its underbelly fading inward from a bright red into something resembling human skin, to match its torso and face, with an off white cloth wrapped around its waist in a semblance of clothes, though they look closer to bandages.

It's gorgeous, ethereal, but what makes Hizashi dizzy with fear, is the sheer size of the monster.

Hizashi knows himself to be a tall man, but the Naga is almost twice his size, its clawed hand looks like it would fit Hizashi's head perfectly in one palm.

Absentmindedly, instinctively, he tries again to free himself, wiggling and trashing pathetically within the Naga's hold.

Only this time, the Naga wakes up.

Hizashi freezes in place, swallowing a whimper of fear, as a low hiss, deep and carnal, rumbles through the cave, down to his very bones, licking up his spine.

The sound of scales scraping along stone fills the air as Hizashi watches as its body uncoils from its ball and straighten out to bring itself upright to its full height, while keeping Hizashi held within its coil.

The curtain of black locs barely hides the blood red eyes glaring down at Hizashi from where it towers over him, before an unnaturally wide, fanged smile splits its face, teeth glinting in the light.

A cold, clawed hand cups Hizashi's chin, tilting his head up to keep him in place as it holds his trembling gaze. "Hello little human. Care to tell me why you were in my forest?" I̶t̶s̶ His voice is deep, smooth, with a hint of a hiss on the softer words.

"Where am I?" Hizashi's voice comes out shaky, but he manages to speak clearly enough, and though he has an idea of his answer, he decides to confirm.

The Naga's smile widens, somehow, as he leans down closer to Hizashi's face, tracking the way his throat bobs when he gulps thickly, and decides to humor him, letting it go for now. He has time and patience, he'll get his answers eventually. "We're in my den. You interrupted my nap, noisy little thing." His eyes are as predatory as one would expect; tracking every twitch of his expression, every bead of sweat trickling down his skin, every breath.

"Are you going to kill me?", Hizashi whispers thickly, voice choked.

"Oh no, sweet thing. I'm goimg to keep you. You'll be my cute little mate, won't you, pretty human? Keeping me warm through the cold?" The creature says with a laugh, teasing and light as he takes in the little hitch in Hizashi's breath.

"They'll come looking for me." Hizashi tries to put as much conviction and strength in his words, he really does, but even he knows that that's not happening. This is the best he could ask for really, considering he's surprised he's even still alive and not in the snake's belly.

The Naga laughs again, low and mean, as he grips the junction between Hizashi's shoulder and neck in one hand and his cheek in the other; ignoring his automatic flinch at the feel of his short claws digging into it hard enough to feel but just shy of breaking skin, eyes condescendingly amused as he looks down at him. "Silly human, you're the only one foolish enough to come this far into my forest." He releases his hold on his face to run his fingers through the silky golden hair lightly, gliding sharp claws through the strands, eyes tracking the way they fall after every movement. "Either way, I will kill anyone who dares to try to take you from me. I will crush them until their bones snap like the twigs of the trees, and their eyes pop out of their sockets like a seed from its fruit." His voice is dark and malevolent, words venomous and cold, yet he says it so casually, as if it's not a threat, or even a promise, but the simple truth; a concise inevitability.

And Hizashi shivers, because he believes him. He knows the Naga would be willing and more than able to slaughter anything that gets in the way of what it wants, and knowing that, he also knows that as he is now, at the creature's mercy, he would swiftly join that category if he tries to deny it.

Shouta can feel the little human's heartbeat pounding from where his tail rests against his ribcage, racing and strong like a rabbit, like prey, and he can't help momentarily squeezing that bit tighter, to feel more of it; the coil of his tail rippling as it flexes around Hizashi's chest, twistimg tighter and pressing into him, testing the limits of his human body.

Hizashi's breath hitches at the sudden constriction, and Shouta smiles, cold and cruel yet playful as he watches the human's face turn red from lack of oxygen, the veins in his neck bulging and straining, his mouth opening and closing in a useless attempt at breathing, much less speaking, before finally loosening his hold again just before it actually turns dangerous.

With stinging, blurry eyes, but trying not to cry, Hizashi gasps and coughs as he tries to gulp in as much air as he can like a man starved, until he's down to slower, deeper breaths, slightly panting.

Lifting his thumb from where it rests on his collar, lightly trailing the razor-edge of his thumbnail down the soft flesh of his throat to his collarbone, just enough to feel, not draw blood, Shouta coos, "Relax little human, we're going to have so much fun together. You are mine now, and I take very good care of my things." Under that unblinking, crimson gaze running over his skin, intense and hot, in the way his touch distinctly isn't, Hizashi trembles in his grasp.

Peering up at the towering serpent, at the monster that wants him as its mate, Hizashi swallows his pride and settles on his decision, lest he becomes his next meal.

"Hizashi," he murmurs, voice ragged and fraying as he sags into the creature's hold, accepting his fate.

Scarlet eyes flicker up to meet chartreuse, brow raised in confusion at both the seemingly random word and the sudden pliant weight in his hold, even as he continues to play with his hair. "Hmm?"

"My name is Hizashi."

The Naga pauses, flicking out its forked tongue, tasting the air, before he shivers; grinning wide and sharp, fangs glinting in the low light of the fire, like he can feel, know, taste Hizashi's helplessness.

His surrender.

"Hizashi." And when he says his name, the tone of it sounding downright sinful falling from the creature's lips, the distinct hiss on the last two syllables dragging out his name with the caress of pure velvet, Hizashi realizes with burning cheeks that that's exactly what happened.

The naga smelled, tasted, his surrender, his resignation at the situation and the acceptance of his fate in the face of his own mortality, his own weakness, and is relishing it.

Chuckling lowly, he releases Hizashi, uncoiling from around him and setting him down in the nest of moss and dried leaves, before leaning in, hovering over him; his forked tongue licking up a stripe on Hizashi's flushed cheek, the cool muscle soaking up his body heat.

"Call me Shouta. I want to hear you scream it for me, hm?" With that, Hizashi gasps as the Naga, Shouta, rips through Hizashi's clothes, letting it fall apart to shreds with terrifying ease, leaving him in only his boots and whatever tatters left hanging by frayed thread.

Bare skin exposed to the air, Hizashi grimaces, wanting to cover himself, to hide, to run, but Shouta's hands are immovable, his presence absolute.

Instead, Hizashi has to simply allow this; lay there and let it happen. He breathes deeply to calm himself as a mortified blush blooms on his cheeks and spreads down his neck and chest.

Naked and vulnerable like this is embarrassing and terrifying, but Shouta lets out a low, pleased rumble at the sight of the exposed, lightly tanned skin, large hands dragging up his legs and torso, cool fingers brushing over his nipples, as he hisses out, "Mm, how lucky I am. A perfect little pet human, delivered to me by the universe itself."

Shouta's expression is intensely covetous, hungry, like he's going to devour him and make him enjoy every moment of it, and despite himself, despite the way that that could turn very real at any moment, to Hizashi's mortification, he feels his gut clench, a traitorous heat pooling there

He swallows thickly, gaze flicking over Shouta's face and body, truly processing his situation and what's about to happen.

Icy fear trickles down Hizashi's spine, making his heartbeat pound in his ears. That fear.....is it the fear of the beast before him, of what the beast will do to him, or something else, something within himself that's far more terrifying?

He's not trembling in shock or terror as he should be, not anymore, not really, which is terrifying in its own way. Because really, he should in fact be so terrified he's unconscious at least.

Hizashi exhales shakily, forcibly relaxing his tensed muscles, trying to ready himself. There's no point in fighting this, and the best way, the safest way to get through this, is to relax.

Meeting Shouta's gaze, Hizashi's breath hitches in his throat, feeling enchained at the dizzyingly hypnotic, pure desire held within those ruby eyes, and his heart feels like it's about to thump out of his chest.

The next moment, the Naga sets upon his prey; the back of Hizashi's head cupped in his large hand, dangerous claws threaded through blond hair, and Hizashi has one blinding second of panic, before Shouta is kissing him, deep and hard.

Rough, vicious and cold, Shouta ravishes him. Hizashi gasps at the sharp sting of fangs scratching and piercing his bottom lip, blood beading in its wake, but his mouth opens all the same, and Shouta simply licks it away before fucking his long, slick tongue into his mouth. Hizashi whimpers, trying to collect himself and think past the thick tongue stealing his oxygen, and the cold hand roaming his warm skin.

The hand in his hair tugs him back, baring Hizashi's throat, and Shouta moves down to his neck, dragging sharp teeth down and his long, thick tongue up the column in a wet, cold line, and Hizashi shrinks away from those dangerous fangs, but he can't contain a gasp when Shouta teases at a particularly sensitive spot behind his ear with his lips.

Even without seeing it, eyes clenched, Hizashi can feel the obvious stretch of a teasing grin against his skin there, just before he does it again.

When the Naga pulls back, Hizashi blinks his eyes open again, only to see that wide, sharp grin, cruel and amused, as his thumb rubs over his bottom lip, kiss swollen and shiny. A low growl rumbles in his chest as a pointed nail digs into the soft flesh there, just enough to sting and draw a drop of blood, which Shouta quickly licks away, ignoring Hizashi's wince.

"Sweet," he hisses, before he moves down the length of his body, cold hands dragging down his chest, fingers splayed, over pert, dusty rose nipples, down the ridges of his ribs, and along his sides, feeling the warmth of his body heat, the softness of his skin; hungry eyes raking across the expanse of flushed skin, and Hizashi's heart feels like it's about to burst.

There's a fine line between adrenaline and arousal, and Hizashi is precariously balancing it like a tightrope, hot all over and quivering.

And when those hands reach his thighs, and Shouta pushes Hizashi's legs apart as if it's his right, helpless to resist, he chokes on his humiliation. Spread wide and exposed entirely, he can see his cock, hard and twitching; the scraps of his clothes doing nothing to hide it.

The Naga lets out a mix of a groan and a laugh at the sight, "Oh? Well isn't this a lovely surprise. My little human is a little slut, hmm Hi-zzsa-sshi?"

Before Hizashi can even begin to try to reply, that slick forked tongue drags up the length of his shaft, slow and deliberate, and he can't help but let out a yelping moan at the contrasting temperature of Shouta's cool tongue on his hot cock.

He licks up the dribble of precum as dangerous hands spread Hizashi's legs further, before pushing them up, close to his chest, almost folding him in half, and holding him there. Hizashi can't help but whimper as cold lips press wet, open mouthed kisses to his inner thigh, fangs grazing the soft skin, and Shouta's pleased growl vibrates against him there, the low rumble sending shivers of despicable excitement down his spine.

Hizashi's heart stutters as he realizes what's about to happen a second before it does.

Scarlet eyes, locked onto his, glow with lust as his tongue swipes over his puckered hole in a languid, filthy lick, and the blond's eyes roll back as his lips part on a low, obscene moan, head thrown back.

The bite of the Naga's claws pressing into his thighs where he holds him, just enough to not draw blood, is drowned out by the sensation of that cold tongue flicking and circling over the tight muscle, mindful of his sharp teeth, before sliding past Hizashi's rim, wriggling his way in and dragging against his sensitive walls, working to relax the muscle; and under that cold touch, Hizashi feels like his skin is on fire.

The monster's tongue is cool and wet and thick and long, and when Hizashi chokes on a gasping moan as it rubs against his prostate, Shouta immediately zeroes in on that reaction, pressing against that sweet spot every time he works his way in.

Hizashi can only moan and pant and whine as the tongue writhes and twists against his walls, stretching him open for him under the pressure; his own body betraying him, surrendering completely to the surprisingly gentle touches and mind numbing pleasure.

Searching desperately for some form of control, his fingers tremble as they tangle in soft dark locks; the only anchor keeping him grounded in the treacherously overwhelming pleasure crashing over him.

Barely registering the sting of his scalp, Shouta feels like his tongue is going to melt off from the tight heat surrounding it, a steady rumble in his chest. His mate's hole is so much warmer than he anticipated, and so small compared to even his fingers, so he knows he needs to prepare and stretch him as well as he can before he takes him. He meant what he said, he takes care of his things, and he refuses to break such a pretty thing, especially so soon.

The Naga basks in Hizashi's sweet little sounds, eyes locked onto the way he thrashes in his hold even as his hips rock on his agile tongue, fucking himself on it and probably not even realizing it. When his cock, flushed and dribbling, twitches once again, Shouta decides he's ready enough for him.

A shaky sob spills from Hizashi's throat as Shouta pulls back just as he's about to cum, tongue slipping out with a wet, obscene squelch, and Shouta can't help the primal growl that bubbles up at the sight beneath him.

His little mate is adorable; gorgeous and tantalizing like this, already looking fucked out. Skin flushed red, parted lips swollen from being bitten, pretty green eyes dazed and glistening from tears, and long, blond hair splayed out like a halo of pure, spun gold in the glow of the fire.

He is perfection personified, all golden heat and beauty, the radiance of it stunning, and he now belongs to Shouta; his own personal sun.

Goosebumps raising along Hizashi's skin, he shudders; the intensity of those crimson eyes dragging over him almost tangible. He watches with a mix of trepidation and depraved desire as the Naga removes the cloth around his waist before stroking himself along his scales, just below his stomach, where the scales there seem to part vertically, looking shiny and wet.

Hizashi lets out a mix of a gasp and a whimper at the sight, as not one, but two monstrous cocks unsheath from the slit; his legs subconsciously parting minutely in shameful welcome, spit slick hole clenching around nothing.

One is situated above the other, the one at the bottom almost the size of Hizashi's forearm, with the one at the top being slightly smaller, but still bigger than Hizashi's; both cocks have a thick girth at their bottoms, tapering into slighy thinner ends, spongy heads almost arrow shaped, the same colour as his underbelly, with small bumps along their shafts matching the red and black mixture of his scales.

Shouta hisses as he grips his throbbing cocks, slick drenching his fingers, and Hizashi is abruptly snapped out of his daze as it finally processes, cold fear settling behind his ribs.

Two.

Legs falling closed, his voice is high and laced with alarm, cracking on some words as he panics. "Wait, wait, wait! You're not going to use both, right?" Hizashi really hopes not, he cannot take two monster cocks. He's barely sure he can even take one! Especially after only the bare minimum of stretching!

Chuckling lowly, Shouta forces Hizashi's legs open again, as wide as they can go, his tail wrapping around his right leg, while a dangerous hand grips the left, holding them in place as he slithers forward to slot himself tightly between his thighs.

"Don't worry your pretty little head, human. We Nagas only use one at a time." The barest brush of Shouta's fingers low on his stomach, sharp nails scratching harmlessly through the light hairs of his happy trail, just out of reach from his flushed cock, has Hizashi's gut swooping; heat newly coiling tight there as the Naga grips his smaller upper cock and lines himself up with his twitching hole. Shouta takes a moment to acknowledge just how small it is compared to him, grinning broad and sharp, before continuing, "Either way, I don't want to break you, darling."

Hizashi drags his eyes away to flick up to meet his, chest heaving, and his heart stutters at the dark amusement held within, just before Shouta says, "Not that much at least. But maybe one day.", and begins pushing in without warning, slow yet unyielding; his spit soaked hole and the Naga's dripping cock thankfully making the slide slightly easier.

Slightly.

As expected, especially with the little preparation, he barely fits. It's perfect torture to slowly stuff his way in deeper, muscles taut as Shouta concentrates on not hurting the little human. He's already so tight, but his hole squeezes and spasms around him the whole time, fighting it, seizing from the pain of being wrenched open. When he's about halfway in, Hizashi's little noises takes on a frantic edge, high and thin, so he momentarily pauses for him to adjust, before wrapping a large hand around his slender waist, tilting his hips up for leverage and steadily feeding the rest of his length in, in, in, and the sweet thing doesn't even fight it at all, just making little whimpers and whines, with fat tears streaming down his cheeks.

"Yess." Head thrown back, grin sharp and wide, the sound draws out with a hiss as Shouta groans low and rumbling as he sinks into his little human's tight heat; warm, velvet walls wrapping around him greedily, sucking him in inch by inch until he's astoundingly fully seated inside after agonizingly long minutes, deep in his guts, while his other cock rests between the cleft of his ass cheeks, drenching his lower back in his slick.

Hizashi's eyes are rolled back as he drools from his slack mouth, trembling like a leaf as he feels every slick, ribbed, thick inch of that monster cock stretching him as far as it would go, carving its way into him, molding his insides to the shape of the Naga's pulsing cock. Head lolling to the side like a doll, fresh tears well up in his eyes even as he stares unseeing at the roof of the cave, the confusing mix of pain and pleasure making his head spin as his own cock twitches against his stomach, precum staining the skin there.

Hands and tail holding Hizashi in place, Shouta raises his hips just a little more while letting him keep his upper half down, almost folding him in half, that perfect hole clenching impossibly tighter, rippling around him, stroking him from base to tip. "Yess, my light. Such a good mate. Perfect."

He's so, so warm, so tight, so truly perfect, but Shouta stays like that for a moment to mercifully let Hizashi adjust to him, chest heaving slightly as he holds himself back from simply pounding into the hot vice around him.

Though, he can't help rutting shallowly in and out, just a few inches, trying to break in that tight heat that bit more, drawing out little gasps and whines, until eventually, with his piercing red gaze trained on Hizashi, he pulls back slowly, bumps dragging deliciously along his insides until only the head stays, before pushing back in just to see it.

To see the way his lips, shiny and swollen, fall open on a sweet moan, the way his body, flushed and glistening with a layer of sweat in the fire light, impulsively twitches in pleasure.

The way his hole clings to him on his way out only to then swallow his fat cock all over again, his rim stretching obscenely around the thick base; to see the way his flat stomach distends from the size of him.

"Fuck, look at that." He groans, all awe and reverence as he grinds in impossibly deeper, Hizashi letting out a hiccuping moan at the feeling.

Hizashi, his little human, is so small in comparison to him, with Shouta's tail alone almost four times longer than Hizashi's entire body, not to mention that Shouta's cocks were made for folk of his own size, not humans who are far less than that.

His little human is so small, and so tight around him, and not for the first time, Shouta can't help but think how easy it would be to break him. To tear him apart from the inside out like this, if he decides to just take him; rut into him with abandon, not caring about whether or not he bleeds or breathes.

And Shouta thinks Hizashi knows it too, with the way green eyes, wide and shaky, stare at the bulge as a trembling hand hovers over it before lightly stroking the potruding skin; the way his voice wavers as he whispers, "Oh, fuck", breath shuddering within his chest, stuttery and heavy, processing just how truly deep inside of him he is.

Yet the clench of his heat around him is obvious, making his hips falter as pleasure zips through him, sharp and pronounced, in the realization that whether Hizashi knows or not, accepts it or not, he likes it; his body honest in the way Hizashi himself is not willing to be.

His forked tongue sticks out, tasting the air, and it writhes as he smells Hizashi's potent arousal permeating the air in the cave,

And oh, Shouta truly is lucky to have found the perfect little human to be his mate.

Sighing softly, gratified and smug, he rolls his hips again, knowing Hizashi can feel the bulge of his cock move within him from where his hand rests, and grins when he hears the gasping moan.

And just that reaction alone, in the way his eyes roll shut, the way his hips grind down instinctively, the way he shivers in pleasure, all because of him, his will to fight cracking and breaking away to make way for acceptance and pleasure and want, is far better than any fleeting pleasure he would get from truly, physically breaking him.

After all, he's breaking him in the best way possible.

Setting a steady rhythm, the wet squelch of his hole filling the air as he fucks into him again and again, slow and deep, bringing his hand up to rest firmly over Hizashi's, pressing against the bulge and forcing a moan from them both at the sensation, and blunt nails scramble to find purchase on his scales, anywhere it can reach, seeming to not even know whether or not he wants to push him away or pull him closer.

Shouta savours every little sweet whine and filthy moan he drags out of him as he releases his leg from his tail's grasp to wrap it around his waist and grip his thigh himself, holding him spread wide and steady; gradually picking up the pace until he's pounding into him with the animalistic abandon Hizashi expected from the start, only now, he can't even begin to think of a complaint as the Naga relentlessly hits his prostate with every maddeningly perfect thrust, throbbing lower cock sliding against him with each stroke.

Mixed with the pain of the stretch, the pleasure of the unique, delicious feel of the bumps along his cock dragging against his fluttering walls and the strange, too deep feeling in his stomach, it feels like his head is being filled with cotton stuffing.

It's humiliating and sordid, but it feels so fucking good. The heat of his arousal is scorching even under the Naga's cool touch, and as Hizashi moans brokenly, he's faced with the horrible realization that he's going to cum.

He's going to cum from a monster's cock, and just the thought of that pushes him that bit closer to the edge.

The thrusts are just too precise, the angle too perfect, and Hizashi shakes at the feeling of being stuffed so full, so deep, so good.

And Hizashi's so close, his cock twitching and leaking a near constant stream of sticky precum, dripping and pooling onto his navel, and he needs to cum.

There's a fleeting thought about his last thread of dignity, before he mentally swats it away because fuck his pride, he needs to cum.

When wide, wild eyes lock onto Hizashi, he can't help but shiver as he feels distinctly like prey in the presence of a predator, and then Shouta grins, slow and sharp. Hizashi barely has time to worry about what that smile means for him when he feels the tail wrapped around his waist tighten around him, just enough to put noticable and purposeful pressure on where the Naga's cock is buried inside him, grinding against his sweet spot, and something pokes at his dick. He looks down, only to confusedly find the tip of the Naga's tail.

The confusion is quickly cleared away when it wraps around the flushed head, sliding and petting against it, teasing the slit. "Cum for me, little human. Let me see you." The Naga's voice is laced with dark arousal, rough and almost breathy, and with the accumulated overwhelming pleasure, it's embarrassingly the last thing he needs. Hizashi wails as his orgasm crashes over him, vision whiting out at the intensity.

Shouta lets out a filthy mix of a laugh and a groan, gleeful and triumphant as Hizashi writhes within his hold making him tighten the heavy coils around him, which only makes him clench tighter in pleasure, crying out, and Shouta follows him over the edge, ropes of cool cum painting his insides, ignoring his whines from mild overstimulation as he rides out his high.

He slows to a stop, before pulling out, the softening length sliding out with a sticky mess of cum, his gaping hole uselessly trying to clench around nothing.

And naively, stupidly, Hizashi thinks it's done.

He's quickly proven wrong when he feels the tip of a cock sliding over his sensitive rim again.

Limbs heavy in his exhaustion, he can barely put up much of a fight other than struggling feebly, legs kicking ineffectively, trying to squirm away and shaking his head.

"I can't," Hizashi begs. "It's too big. Please, it's too m-mm!"

The Naga doesn't stop, sinking inside again with his impossibly larger lower cock. He's so wet and well used by now there's almost no resistance to push through.

Almost.

Head thrown back, a pained gurgle spills out, unbidden, from Hizashi's lips feeling like his heart is in his throat from the radiating pain. He can't figure out how to swallow around it, saliva dripping out of the corner of his mouth.

His chest heaves as he squeezes his thighs around Shouta's massive waist, squirming around as much as he can, arching as he breathes through the mind numbing stretch of the Naga's monsterous cock splitting him open so thoroughly, bullying his walls apart and shoving himself into his sloppy hole, filling him up in one smooth move; his stomach tingling and clenching with the confusing mix of discomfort and pleasure of being far too full.

The Naga's coiled tail around Hizashi's waist tightens, holding him in place, and he groans at the feeling of his own cock bulging against his little human's stomach where his tail rests.

He's so raw and sensitive inside, but the Naga barely pauses long enough for Hizashi to adjust to the new stretch, almost immediately fucking up into him rough and fast, both hands still gripping his legs, holding him in place, muscles flexing beneath his scales as he guides him up and down his cock like nothing more than a toy for the monster's pleasure.

Shouta fucks Hizashi at the same unrelenting pace, with the same sadistic accuracy as before, if not more so, and Hizashi can only cry out in his hold as the sensation flip flops between pleasure and painful overstimulation.

The mess of his cum and slick splattering and dripping down Hizashi's quivering thighs every time he's filled, makes the loud, wet slapping of his hips against Hizashi's all the more erotic.

And Hizashi feels so fucking pathetic like this; stuffed full of a monster's cock, splattered in cum, and feeling good from it.

Shouta let's out a rumbling hiss as he removes his tail from Hizashi's slender waist to see himself moving under the stretched skin there; the Naga's sensitive upper cock bouncing against Hizashi's sack with each thrust, drenching his cock in his slick, pulling noises he's never even heard himself make from him with every stroke

Limp and shuddering, he barely registers when one of his legs are released, hooked over the Naga's waist, until the now free hand is exploring his body some more, bruising and scratching at the soft skin.

"Fuck, look at you. You love this don't you?" The Naga coos, tone mocking, but unable to fully mask the breathless awe within as he slows his thrusts to deep, languid strokes. Whatever little bit of fight he might have had at the beginning of all of this has been perfectly fucked out of him, and Hizashi can only manage a pathetic little whimper as he's thoroughly used; the Naga's pace staying at that steady, deliciously deep pace with no signs of stopping.

"You are truly so very pretty like this, Hizashi." He hisses, low and cold, a cruel smile making its way onto his lips, his fangs glinting in the low light as his lascivious gaze drags over his skin. Dipping his head into the crook of Hizashi's neck, he murmurs, letting his fangs graze over the sweat-slicked skin there, "If I bite you now, Hizashi, then you'll be truly mine."

Truly Shouta's human, Shouta's mate; Shouta's.

Of all the partners he's had in his lifetime, he's never bitten them, never taken a true mate, as the marking is only ever meant to be given to one person, and Shouta desperately wants it to be Hizashi.

Even more so, Shouta wants Hizashi to want it too, at least a little; at least to hear it.

Pulling back, Shouta tangles his fingers in those golden tresses and tugs, tilting Hizashi's head back. The slight sting of his scalp brings Hizashi back into focus, their eyes meeting. His scales are a cooling balm on his warm skin, but the look in his crimson eyes boils his very blood; pure possession, devotion, obsession.

"Be mine, Hizashi." he rumbles, low and clear all as he gently fucks into him. "Be mine and I yours. Let me take you, let me keep you. Let me worship you." Hizashi shivers, the Naga's voice a velvet caress along his skin.

As Shouta fucks him, slow and almost loving, he whispers sweet promises of the life he would have. How he would never want for anything. How there would be no more long nights working, with little to no recognition, no more dealing with the assholes in his life. No more worrying about others' opinions.

And fuck, it sounds perfect. The words trickle like warm honey down Hizashi's spine, sweet and sticky, clinging to the cords of pleasure running through him and seeping into the little cracks of his resolve, settling into his very being.

But could he really willingly leave it all behind? His career, his friends....

Seeing the hesitation in the furrow of his brow, Shouta releases his grip on his hair to cup his cheek in his large hand. The hold is surprisingly gentle, light like Hizashi is something truly precious.

"Please don't fight me anymore, my sun." He whispers, a pleading command, and a heady mix that crumbles Hizashi's hesitation, because if he's honest with himself, he doesn't really have anything he's actually attached to, does he?

A beat passes before he whispers, breathy but clear, "Yours."

That single, simple word sends a full body shiver through the Naga as he smiles wide and sharp, before leaning to bury his face in the junction of Hizashi's bared neck and shoulder. "Thank you." He breathes, pressing a soft kiss to his pulse, before his sharp fangs pierce through the soft skin there to inject his claiming venom, as his hips speed up into that mind numbing, brutal pace.

Letting out a gasping sob, Hizashi loses himself in it; his senses flooded with that heady mix of pain and ecstasy. Somewhere in the back of his mind, he knows that the bite would surely scar, but he doesn't particularly care.

He arches into Shouta's touch as best he can without ripping his own throat open. "Fuuuck~" he whines, high and breathy, blunt nails dragging down his arms for something to ground himself with, legs tightening around his waist as he clenches around him. All at once, it's too much, too fast, but he might actually cry if the Naga tries to stop.

He can feel another orgasm ready to crash over him, just on that very edge as his hips move to meet the Naga's thrusts, their cocks rubbing together in a delicious friction, but it just isn't enough. He needs more.

"Shouta!" He slurs, drool dripping from his slack lips. "Shouta, please."

At the sound of his name falling from his mate's lips, the Naga moans against him, cock twitching within him as his thrusts become more erratic.

Hizashi's whole body feels alight, raw and hyper-sensitive. It hurt, a constant cycle of pleasure and overstimulation; everywhere he's touched feeling like he's being poked with frozen pins and needles, yet the painful sparks are accompanied by a swirling heat.

Shouta pulls back from his neck, his split tongue dancing across the wound on his skin, giving the sensation of a faint tingle as it heals and closes. Reaching between them with one hand while the other grips Hizashi's waist, Shouta murmurs, a string of babbling really, "So good for me, so fucking pretty, fucking perfect little mate—" as he takes Hizashi and himself in hand, the wet slide of it lewd and perfect. He pumps once, twice, and the direct stimulation to their sensitive cocks pulls them both over the edge together for a second time, splattering their release between them.

Hizashi cums screaming the Naga's name, the pleasure washing over him in waves, the world around him fading until all he could feel and see is Shouta as his own body tightens around his pulsing cock, and Shouta shakes, groaning as the spasming walls milk him for all he's worth, fucking in harder as he releases deep inside of him.

Hizashi moans, long and low as he's filled and drenched with wave after wave of cum, shivering deliciously at the edge of overstimulation as the Naga fucks him through their orgasms.

Maneuvering his limp body, Shouta pushes into the spasming channel a few more times, marveling over every whimper, moan and mewl he lets out, all for him, before laying Hizashi on his back and pulling back to admire his thoroughly debauched mate. Completely boneless, collapsed like his strings were cut, those sweet moans turn to whines as the softening length slides out with a gush of cum, the used hole sloppy and gaping open despite his best efforts to instinctively clench around the empty feeling. As Shouta guides Hizashi's legs down into a more comfortable position, he watches entranced as his cum dribbles out of the loose hole, obscene and filthy, and he can't help the swell of possessive pride that settles in his chest at the sight.

"Looks like I made a bit of a mess," the Naga chuckles, catching the trickle of mess with a finger, before carefully pressing the pad of it to his puffy hole to keep him plugged full of his seed for just a bit longer, just because.

His words are almost lost to the cottony stuffed ringing in Hizashi's ears, but the touch to his sensitive, sore hole drags out a breathy, keening moan, weak and broken as his muscles tingle and throb.

As Hizashi comes down from his high, heart beating in his ears, throat dry, and vaguely feeling cool hands caressing his sides and thighs, he tries to regain his senses.

Haphazardly wiping the tears and drool from his face, breathing heavy, his mind reels.

He could barely believe this was real; that he'd just been fucked by a Naga, the literal mythical creature, a monster, and is apparently now mated to said monster.

His body trembles, jittery, and his legs ached where the Naga had held him; he can feel the wetness of the the monster's cum and slick leaking out of him, smeared around his hole and dripping down his thighs.

It's filthy, nasty, in all the ways that matter, yet as he looks up at Shouta, at the monster looming over him, arrogant and tall in his nudity, cocks soft and shrinking back into their slit but still shining with slick, yet calm and graceful in even the most minute movements, Hizashi feels something settle in his chest, lungs tight.

Because what strength that body holds, Hizashi thinks, in those lithe muscles and sharp claws, and scarlet eyes and gleaming fangs.

He tells himself it's fear he feels. Trepidation of what is to come, of what will happen to him when the creature inevitably tires of him.

Yet, unlike the first time he'd laid eyes on the Naga, he doesn't want to run. As he regains himself, it isn't regret that sets it or even resignation, but instead a resolve built from his circumstances.

The shadows of the cave waver as the flame shivers against the Naga's silhouette, the embers flitting through the air like fireflies, and Hizashi drifts off to the sound of the crackling fire and the low rumble of Shouta's voice saying something that is lost to the night.

*****

At one point, on the second day there, while resting but feeling curious, Hizashi finds the very treasure he came all the way out here for in the first place, tucked away among the Naga's belongings.

It turns out Hizashi found the cave he was looking for after all. He just didn't expect it to be a Naga's den.

And over time, Hizashi does what he can to keep himself in the Naga's good graces. Since that day, he's been treated well, far better than he expected.

Though, that wasn't a very high bar, since Hizashi honestly expected to be nothing more than a toy, a doll to be fucked and discarded at the creature's whims, but instead he's pampered and cared for, adored and worshipped by a creature much closer to divinity than he.

Though, for all that it wasn't just about sex in surprising ways, it was still equally about that pleasure, that sweet torture.

Hizashi should hate it, should be terrified. Instead, he hates admitting that he doesn't.

He tries not to think too much about what his mentor, Nezu, or Oboro or, God forbid, Nemuri, would say, if they saw him now.

Though as the days went by, thoughts of guilt and shame were melted and washed away by mind numbing orgasms almost every day, and distracting little sweet gestures, all courtesy of Shouta, and he just can't help drowning himself in these desires, hopelessly aroused by it all. The danger, the adventure, the pleasure; Shouta's dark amusement, teasing, fanged smirks and his arrogant, vulgar words, not to mention the size of him.

Of course, throughout all that time, and after, no one but Shouta sees the way Hizashi settles in like he'd always meant to be there, and no one but Shouta would notice that when the light catches it just right, there's a subtle swirl to Hizashi's eyes, a hint of red mixing in with the green.
