summary: tìsom: [tI."som] P F n. heat

Tsu'tey is a strong mate; he is cautious, considerate, and protective, and he always provides for you.

And yet, human/Na'vi relationships come with a learning curve. That learning curve comes with surprises regarding certain biological urges

read it on ao3!

“You must squeeze your thighs more, ma’yawne.”

“I’m trying,” You complain, shifting your weight on the back of the enormous direhorse. “I don’t think she likes me.”

Tsu’tey gestures pointedly at the spot where his queue is connected to the direhorse’s, linking them mentally. His tsaheylu is probably the only reason his direhorse hasn’t thrown you into the dirt by now.

“We are connected,” He points out to you, as if you’ve missed his meaning. “She could not dislike you.” Then he grins, the sharp points of his teeth poking out from beneath his lip. “More than likely, you are too little for her to feel on top of her.”

You roll your eyes, beginning to get irritated. This whole riding exercise had been his idea in the first place! You were perfectly content on the ground! It was pointless practice considering you wouldn’t be able to ride without Tsu’tey around, anyway.

“Come,” He says, and his hand lands heavily on your thigh, big and warm. “Squeeze your thighs. Show her you are there.”

It doesn’t matter how often he touches you; the feeling of his big hand spreading over you makes you feel so impossibly small. It’s such a heady feeling, and you bite back a grin instinctively. God, you don’t think you’ll ever get used to that. He’s being so touchy today, it’s driving you a little crazy.

This time, when you squeeze your thighs the animal beneath you responds by taking a few cautious steps forward. You let out a startled laugh, clutching at the direhorse’s neck and turning to give Tsu’tey an enormous grin.

“Oh shit, look! She’s moving!” You yelp.

Tsu’tey only hums in response, though he’s not doing a very good job at hiding the way his own mouth is twitching. It’s pretty obvious that the only reason the direhorse is moving at all is because Tsu’tey is guiding it through the tsaheylu, but you appreciate that he’s allowing you to take the credit for it anyway.

“You’re a natural, demon.” He says, the familiar old insult dripping with unmistakable fondness.

You perk up at the compliment, despite the fact that it’s really just Tsu’tey leading you around on the pal’i. You feel like a little kid going for a ponyride at a fair, but damn if it isn’t unexpectedly fun. You start to relax into the gentle sway of the direhorse’s gait, enjoying the weight of Tsu’tey’s hand on your thigh. It’s surprisingly peaceful, especially when Tsu’tey’s thick thumb strokes over your thigh like he just can’t help himself.

When the pal’i begins to step away from the clearing in the back of the village towards the forest, you shoot Tsu’tey a look with raised eyebrows.

He just smirks at your questioning expression, clearly amused. “You do not trust me?”

“I trust you.” You say immediately. “But your pal’i is barely tolerating me as is-”

“She is tolerating you just fine.” Tsu’tey interrupts you lazily, reaching up to stroke a broad hand over his pali’s neck.

There’s no argument you can think of for that, so you decide to just go along for the ride. It’s a beautiful afternoon, and it’s the first time in a while that Tsu’tey has managed to free himself up from the various duties that he usually performs for the clan. There’s a certain looseness to his shoulders that tells you he’s enjoying this just as much as you are, especially as his hands never stray from you once.

The forest is alive in the late afternoon sunshine. Ancient roots erupt out of the dirt and fan over the ground like hairs, and the moss that covers the trunks of the trees is such a deep green that it almost seems like paint pigment. Tsu’tey is careful to lead the direhorse around any tripping hazards, his hand on your thigh keeping you steady and safe on the direhorse’s back.

You hadn’t been lying when you told Tsu’tey that you trusted him. You’re content to go along with his little ride, resting your own smaller hand on top of his as he leads your mount along through the trees. Eventually, Tsu’tey leads the direhorse through the trees into a tiny copse of glowing flora.

“Wow.” You start to smile, lifting your head to gaze around at the phosphorescent fungi-like growths sprouting out of the ground and surrounding trees. It’s stunning, just like most of Pandora. The alien beauty of the planet still manages to steal your breath away sometimes, no matter how long you’ve been here.

You’re so distracted by the plants around you that you don’t notice Tsu’tey disconnecting his queue from the pal’i. When his hands land on your waist you let out a soft noise of surprise that’s cut off as he lifts you bodily from the back of the animal, swinging your legs around and placing you gently on your feet in front of him. He slaps his palm lightly against the direhorse’s rear, sending her careening into the forest to graze.

“I thought we would spend the afternoon outside the village.” He says once you’ve got your balance, and he reaches out to fiddle with your exo-mask to ensure it’s firmly attached to your face.

That sounds really nice. The Omaticaya encampment has become home to you, and the people are so gracious when it comes to accepting you considering what your kind has done to their planet, but sometimes the urge to just escape somewhere far from all the curious, prying eyes of the villagers.

When Tsu’tey lowers himself to the spongey moss floor of the forest, you’re quick to follow after him. It feels like laying on foam, and you end up rolling on your back and gazing up at the canopy of trees far above your head. You’re vaguely aware of Tsu’tey settling himself beside you, laying on his side so he can look down at you, but you’re distracted by the luminescent moss cushioning the ground where you lay.

“You’re staring at me.” You murmur, a smile tugging at your lips.

You don’t turn your head, but you can see Tsu’tey’s big golden eyes fixed on your face out of the corner of your eyes. His gaze feels like a physical weight pinning you in place, his tail undulating lazily in the air as he watches you.

“I am allowed to stare,” Tsu’tey’s smooth voice rumbles, sending a tiny little tremble running up your spine. “I am thinking.”

“Oh yeah?” You’re trying to sound as casual as possible, but you’re sure that you fall way short. “What are you thinking?”

Tsu’tey doesn’t speak immediately. He’s quiet long enough that you raise your head to look at him. Like this, his gaze is even more intense. His eyes drift from your face down to your shoulders, over your chest, down your hips, and then along the length of your legs.

The atmosphere on Pandora is humid and hot like the rainforests of Earth, and the heat had gotten to you in the last couple of days – you had abandoned the standard RDA-issued cargos and tank top in favour of one of the sun-dresses that you had brought with you from home. The little dress is impractical but pretty, a truly self-indulgent treat for yourself, and it certainly seems like Tsu’tey likes it too.

Eventually, his big eyes trail back up to your face and settle there. “I am thinking that I want you.”

Your cheeks heat, skin going prickly as you shift where you’re laying. Ah. That certainly explains the heat in his stare.

“You had me this morning,” You remind him, biting your lip as you grin at the memory.

His ears twitch, and his teeth flash as a matching grin grows across his face. “Yes. I remember.”

When his hand comes creeping across your stomach, you snort. The two of you have come a long way from your first meeting, when he had seen you as nothing more than an annoyance, a demon. It’s almost hard to believe that it’s the same man who is looking at you now, with his twitching ears and pupils blown wide.

You turn to look at him properly, but this time you note the way his tail is undulating across the soft grass and the way that the little bioluminescent dots scattered across his face and body are emitting a soft but insistent sort of glow. The expression on his face is… odd. His pupils are blown much wider than usual, and the way he’s watching you is eerily reminiscent of a predator. He’s always been intense, but this kind of a gaze is a bit much, even for him.

“What’s up with you?” You ask, laughing a little as you reach out to playfully grab at his twitching tail.

It’s something you’ve done plenty of times before – Tsu’tey is always so serious and austere, and it usually makes his stern veneer crack a little when you initiate such a playful move. He’ll usually snort and swat at your head, or roll his eyes and tug at you in return. However, that is not what happens this time.

When you wrap your fingers around the velvety soft, whip-like tail and tug, Tsu’tey’s head falls back as he lets out a groan that sounds as though it’s been punched out of him.

You whip your hand away at once, eyes growing huge. “Oh, god! I’m so sorry, did I hurt yo-”

The rest of your sentence is lost as the air whooshes out of your lungs – Tsu’tey’s entire big-ass body has just rolled over onto you, trapping you beneath his hot skin and big arms. He’s still careful to keep most of his weight off you, clearly conscious of crushing you, but the bulk of his body presses you right into the cushy moss beneath you. His face presses right into your throat, and you can feel his hot breath as he takes deep, snuffling inhales.

“Fuck.” He grunts, and despite your surprise you have to bite back a laugh. It’s always a little comical to hear him use human sayings that he’s clearly picked up from you.

“Fuck,” You echo back in agreement, still trying to catch your breath as he bears down on you. It’s as though he’s trying to press your bodies as tight together as he can manage. “Not that I’m complaining, but what’s gotten into you?”

“Tìsom,” He groans, and you jolt as his big hands land on your thighs and he pulls you to meet his crotch.

The hardness there is unmistakable, his tiny tewng doing hardly anything to conceal it. He grinds against you, the movement and the pressure sending little zings of pleasure shooting right up into your lower belly.

“Tìsom,” You repeat, bewildered. You don’t know this word, and he doesn’t seem to be too fussed about explaining it to you.

“It started this morning,” He mumbles into your neck, his lips leaving wet trails across your skin as he takes a series of deep breaths. “It has gotten stronger through the day. I need you now, I wish to have you right here, my little mate.”

You still aren’t sure what he’s talking about, but when he humps up against you again you’re pretty quick to abandon your curiosity. He certainly had been horny this morning when he had rolled you over and fucked you right there in the bed, but that had been different. It had been softer, tinged with a hint of desperation but lacking any real urgency. This is different. This feels as though he’s trying to crawl right underneath your skin.

“Tsu’tey,” You gasp as his hands begin to ruck up the soft fabric of your sundress. Damn, you knew it was impractical to wear the damn thing, but you can’t bring yourself to regret it when he peels himself away from your throat so he can look down at you with fierce interest as he pulls the hem up around your waist.

He grunts softly at the sound of his name, his gaze swinging up towards your face. His eyes look a little glassy, but he focuses on your face and you see his pupils have blown so wide that all you can see of his iris is a thin golden ring around the edges.

“What is tìsom?” You ask, watching with widened eyes as he takes deep, snuffling breaths.

“Heat,” He grits out. “I am- I can smell you. I must-”

He pushes himself up onto his elbows and begins to shuffle down the length of your body, but you barely even notice his progress. Your mind has stuck on the first thing he had said; heat.

Surely that doesn’t mean what you think it means. Do the Na’vi have heat cycles? You haven’t heard anyone bring that up before. Good god, why has no one brought that up before? That seems like something you ought to know!

Your thoughts don’t get to spiral any further, because Tsu’tey’s big head pushes its way between your thighs. Your legs fall open to make room for him instinctively – it makes you feel like a wanton idiot, but then he’s nuzzling you right at the juncture of your thigh and suddenly it doesn’t matter anymore. Your thoughts are washed away by the feeling of his damp, hot breath against you.

He takes a soft, snuffling breath, then sighs out a little moan. “You smell so sweet, ma’tawtute.”

His teeth graze over the cotton of your panties, causing your spine to lock up at the sensation. That should definitely be embarrassing, you think. It certainly shouldn’t have you throbbing, tightening, hunching your shoulders.

“I don’t-”

With a purr, he wedges his nose between your thighs. You let out a short, startled shriek, and grab a handful of his braids. His tongue is so big, a swath of wet warmth that can lave over your whole mound and everything below it in one lick. In a few more licks your panties are soaked from both sides.

When you can't stand the feel of damp cloth on you anymore you push his nose away, just enough to let you lift your hips and drag the panties off and kick them aside.

He only barely allows you enough time to toss them aside before he’s pushing his head right back between your legs, his face pressing right up against you with a needy groan. His tongue pokes out yet again, but this time the rough, hot, wet texture is pressed right up against your bare flesh. The sensation is dizzying, and you lean your head backward, pillowed against the soft moss, looking up dizzily at the sun through the boughs of the trees. You rock your hips into the press of his tongue, feeling like you’re melting under it.

You had assumed, when he said heat and then rolled atop you, that he was about to spread your legs and pound you right into the ground. You certainly wouldn’t have been opposed to that, but Tsu’tey remains entirely preoccupied with his face buried against your pussy – he shows no sign of shifting at all.

He sucks on your clit, and when you tug at his hair he lets out a growl that reverberates against your core and has you clenching around nothing. His tongue quests lower, and you let out a pleasured little sigh as his tongue presses against your slit and then in – the texture of his tongue is rough and textured, and you squirm against his face as he licks at you with such enthusiasm that it leaves you reeling. You know that you’re wet from your own slick already, but Tsu’tey is messy as he slurps at you. His mouth leaves you sodden and dripping, the coarseness of his tongue leaving you gasping as his flat nose bumps and grinds against your clit.

Just then he tilts his head, searching for an angle that lets him slide his tongue deeper in. It's too big – at least, it ought to be too big, but it's hot and wet and thick and your body just wants that, wants him. Caught without any breath to moan, you reach down with both hands and spread your own swollen lips. He licks hard, growling into you, so you feel the sweet thrum of it right on your clit.

“Oh, fuck, oh yes,” You gasp out eagerly, lifting your head so that you can look down at him.

Though his head is still buried between your thighs, the rest of him is moving restlessly.

His hips roll insistently against the soft, spongey moss beneath him. His cock is hard and leaking, the bulbous tip of it glowing insistently as it glints with its sweet little bioluminescent dots. He grinds relentlessly against the soft, cushioned forest floor, grunting out soft little moans of appreciation right into your core.

The sight of him so lost in his own pleasure is both startling and impossibly arousing, and with a short sob you grab hold of his hair, clenching your fists into the roots of his braids. He growls once more, like it's an affirmation, as though he’s acknowledging your wordless noises of desperation.

But then, shockingly abruptly, he pulls his head back and shoves himself back up onto his elbows, looming over you.

“It is not enough.” He says, and you’re absolutely floored to hear the edge of a whine in his voice.

This is Tsu’tey, the proudest man and the fiercest warrior you’ve ever met. To see him like this, sweaty and pouting and frenzied as he humps the ground and tries to bury his whole fucking face inside you, is crazy.

“What do you-” You start to ask, but he seems to have gotten into the habit of interrupting you today.

His arms hook around your thighs, which had been splayed out over his biceps, and then in a move so fast that you’re not even sure how he manages it, he flips your positions. When you manage to reorient yourself, you find yourself perched on his stomach – he’s the one laying on his back against the moss now.

You start to grin. He may be acting strange (in heat! Your brain screams at you. Your big sexy alien is in heat!), but this position, at least, is familiar. You know how to take care of him like this. You reach to pull your dress over your head, tossing it to the side before looking back to him with a cheeky grin.

“Ah,” You say playfully, glancing over your shoulder before reaching back to grasp his cock where it’s laying proudly against his thigh. “You want me to ride you, big guy?”

Fuck, his cock is hard. It actually surprises you when you wrap your fingers around it – it feels like a goddamn lead pipe.

He lets out a punched out groan as his lip curls back over his teeth, tossing his head back against the moss as he hisses towards the sky. He looks almost feral, lost to his own arousal in a way you’ve never seen before. And yet, what he says next surprises you.

“In a way,” He grunts, his hips twitching as he humps his cock into your small grip. “Sit on my face.”

You still and blink, surprised. “What?”

It’s not that the request is shocking (you’ve never actually done that with him, but damn the request alone has jolts of electric excitement shooting up your spine), but the fact that he’s asking for this when his cock is swollen and oozing insistently against his belly is absolutely bizarre.

When you release your hold on his dick his hips hump into the air, as though seeking your touch. He looks so desperate – how could he turn down the chance for relief?

"Sit on my face." Tsu’tey repeats, overenunciating each word as though he were talking to someone especially stupid. There’s no way of misunderstanding him this time, and his ears are pressed back against his head as he awaits your response.

“But-” You start, glancing over your shoulder at his painful-looking erection.

His big hands land on your ass, and he uses his grip there to pull you so insistently that you slide right up to his chest. Fucking hell, he’s really insistent about this, and he’s so much bigger than you that manhandling seems to come easily to him.

Hesitantly, you shuffle forward until you’re hovering awkwardly over his face. Like this, naked and exposed as Tsu’tey’s hands continue to pressure at your ass, you feel more flustered than you’d like to admit. Especially considering the way that he’s staring up at you with wide-eyed, open-mouthed eagerness.

“What if I smother you?” You ask, cheeks hot with embarrassment. God, you don’t think you’d be able to live that down.

“I would be proud to meet such a fate.” He grunts, his hands kneading and squeezing at the soft flesh of your ass like a goddamn cat.

“Fucking hell.” You mutter, but you can’t stop yourself from letting out a soft, breathless laugh.

His impatient eagerness is wearing away at your hesitance, and the next time he tugs at your hips, you allow yourself to be manoeuvred so that you’re lowering yourself over his face. When he purses his lips and blows on your exposed, wet sex, it nearly causes you to overbalance in surprise.

"Oh!"

"Come," He presses a sloppy kiss to the inside of your thigh. “Let me taste.”

He wraps his forearms around your waist and pulls you down firmly. As soon as you’re settled over his mouth, he starts licking immediately, and you're utterly stunned by the wave of heat that flows through your belly. You have to stick out a hand to grab at his shoulder just to stay upright, your upper body curling over as your hips rock reflexively against the hot, wet heat of his mouth.

"Oh, shit." You blurt, a little overwhelmed as he licks and sucks at you with a single-minded determination that has your thighs trembling around his face in minutes.

Judging by the pleased little gasps he keeps letting out against you, he doesn’t want to be anywhere else right now. His big hands wrap around your thighs, the size of them making you feel so tiny in comparison as he encourages you to squeeze your thighs around his head.

It doesn't take long before you’re grinding against his face, chasing his tongue against your clit. His mouth is so overwhelmingly hot, so wide and all-encompassing as he sucks at you, and his tongue is so wet and coarse as it rasps against your swollen, sensitive pussy.

You might have been embarrassed about the way you’re humping against his mouth if it weren't for the way that your rocking against his face earns you a soft, hungry whimper from him as he wraps his arms around your back and encourages you to ride his face harder. Your hairline is damp with sweat. You wonder if his tìsom is contagious – it feels like you’re boiling from the inside out.

One of your hands drops down to tangle in his braids, already all messed up from your earlier tugging, and a hard suck to your clit has you jerking over his face, accidentally yanking at the fistful of hair in your hand. You’re not expecting the way he gasps, or the way his hips thrust into the air behind you.

"Oh fuck," You gasp. "Do you like doing this that much? Are you- can you breathe? Will you tell me if you-"

Tsu’tey makes an impatient sort of sound before tilting his head back from his position between your legs. His chest is heaving, and his brow glitters with sweat — he looks ethereally beautiful, and you’re stuck for a moment about how damn lucky you are.

“Ma’tawtute, the tìsom will rage until I have satisfied my urges,” He says on a sigh, the proud slope of his brow all furrowed with need. “Allow me to satisfy myself with my mate.”

Well, fuck. How could you ever deny him that?

"Yeah," You choke, your eyes fixed on his mouth; it's swollen red and shiny, and you can't stop looking at it as he runs his tongue along his bottom lip. “Okay. Please, then-”

You don’t need to finish your request. As usual, he reads you without you ever having to say a goddamn thing.

He just grins, wild and unrestrained and looking truly fucking feral, before ducking his head back to start licking eagerly at you all over again. Your breathing is embarrassingly heavy at this stage, but even worse than that are the whimpers that you can't quite keep from spilling over. When your hand clenches and tugs at his hair, he lets out a pleased moan that vibrates right up into your core.

This time when he digs his long fingers into the soft meatiness of your thighs and encourages you to rock against his face, you do so without question. You’re rewarded with a throaty, whiney hiss, and his hips thrust sharply up into the air when you grind your clit down into his waiting tongue.

You can hear the slap of his cock against his belly as he humps the air, and you gasp at the sheer sensation of it all. It feels as though your nerves have been set alight.

"Fuck," You whisper, grinding down on his tongue. "I- there-! Shit, Tsu’tey, I-"

You’re really not making all that much sense, but he seems to like your flustered desperation because his hips continue to thrust lazily as he dry humps the air. That just isn't enough for him, apparently, because he releases one of your thighs as his right hand snakes down so he can touch himself while he eats you out.

The slick sounds of him working his cock are mostly drowned out by the soft, breathy moans he keeps making into your pussy every time he licks into you. His stomach keeps tensing as his hips flex, throaty hisses muffled by you and the way you’re rocking into his mouth.

When Tsu’tey had told you to sit on his face, you hadn't actually thought he would get anything out of it. Perhaps that's why watching him fall apart between your legs is so compelling, and it's causing the sweet, hot tension in your lower belly to coil tighter and tighter until you’re a trembling wreck, ready to shatter apart.

“Oh,” You breathe, your eyes squeezing shut as you clutch at his hair and gasp. “I’m- I’m going to-”

“Yes,” He snarls, still muffled between your legs. “Do it, so sweet, let me taste-”

You’re not the only one close to release – you can tell by the way his hips are bucking, the way that animalistic little growls are tearing their way out of his chest, how fast and rough his fist is pumping at the swollen length of his cock.

When his tongue dips into your folds and locates your clit with absolute precision, your back arches as you come with a little scream.

You grab at his hair to try and keep his head in place, but he doesn't slow at all as he continues to suckle at you through your orgasm. In fact, his one remaining hand actually clutches at your ass to encourage you to ride it out on his face.

By the time the waves of your orgasm begin to ebb away, you’re shivering and bordering on the edge of overstimulation. And yet, you can’t bring yourself to pull away. Not when he’s suckling at the slickness of your release as though he can’t get enough of it, and not when his goddamn toes are curling into the glowing moss beneath you as he fucks his cock into his own fist.

The sight of him so lost in his own pleasure is both startling and impossibly arousing, and you let out a quiet little noise of surprise as you watch the dots on his cock flicker right as the head pulses. Then he’s growling, his chest rumbling with the force of it as his release erupts from him, ropes of creamy cum spurting onto his belly.

Finally, you pull away from his face, falling back onto his chest with a wheezy gasp. There are still aftershocks of pleasure rocking through you as you shiver; the two of you are sweat-slick and overheated, panting and gasping, but you savour the feeling of Tsu’tey’s naked skin against yours as you clumsily push yourself down so that you’re laying across his chest.

Still catching your breath, you reach out to cup his face fondly. “Oh fuck, look at you.”

When he raises his head, you’re greeted with the sight of his face slick and shiny from his own drool and your release. He’s so messy and his eyes are still blown wide, his ears twitching as his brow slackens into an expression of pleasure. The dots around his face are still glowing, but the intensity of it has dimmed for now.

Your own body goes slack against his, your masked face nestling into his shoulder. The cum on his belly squelches a little when you settle over him, and you can’t help the tired snicker that escapes you.

“So,” You mumble in an exhausted little drawl. “Are you satisfied, big guy?”

That gets you a laugh in response. It’s a rumbly sort of chuckle, and you enjoy the way his chest vibrates under yours. To your surprise, he doesn’t sound as tired as you might have expected. He’s caught his breath much faster than you have, despite the fact that he has significantly more reason than you to be winded.

“It is tìsom, foolish thing.” He murmurs, nuzzling his soft nose into your temple. You can feel him bear his teeth in a grin against your hair. “I will not be satisfied until it is done.”

That’s when you feel the hot, thick press of him against the sensitive, puffy flesh of your pussy. He’s still so hard, as though he had never come at all. Your heart skips, belly clenching in excitement.

Well. You were his little human mate, after all. If he needed help with his tìsom, his heat, of course you would help him out with it.

The swollen head of his cock catches against the slickness of your pussy, and you moan softly as he presses just slightly into you, just enough to tease you with the stretch of it.

It seems like you have a long night ahead of you.
