Late at night in Hell’s Gate, you lie with Jake Sully curled up in your cot. The both of you hardly fit onto the shitty, narrow mattress, but you don’t mind, tangling your limbs together till you’re not quite sure what’s yours and what’s his.

The sheets smell like sex and sweat, still fresh enough to be pleasant instead of musty. Jake’s chest rises and falls a little quicker than usual underneath your head, his heartbeat still coming down from the happy ending of a couple minutes prior. Being with Jake is always good, regardless of the adjustments you have to make for his wheelchair. There’s no pinning you to the wall or kneeling to take you from behind, but his fingers and tongue are more than skilled enough to make up the difference.

This, though, is probably the best part. Laying together in post-coital haze, skin sticking to each other, warm breath hushing into the quiet air. You nuzzle sleepily into Jake’s chest, content to forget where you end and he begins, just one big puddle of spent energy and lingering, fuzzy affection.

"Mmm,” Jake murmurs, shifting his head to press a kiss to the top of your head. “That was good.”

You mumble something wordless in agreement, nestling deeper into his chest. It’s one of the only times you get to feel smaller than Jake, tucked up underneath his chin. Jake likes it too, you know; you can tell by the way he’s always pulling you against his chest while you’re in bed, wrapping you up in arms kept strong by maneuvering his wheelchair around.

“Baby,” Jake speaks again, his voice dropped rough and low. “I got a question.”

You yawn, wanting to push your face back into the hollow of his throat and tell him to ask you in the morning. It’s been a long day in the labs, your eyes strained from hours of running over data screens and yesterday’s logs. Jake’s got other ideas, digging his chin into the top of your head like he knows you’re trying to slip into sleep.

“Wha’?” you grumble, rolling over a bit so you can look up at him. In the dark of the room, not much of Jake’s face is visible. Being a lab geek has its perks, but you’re still only an intern, and that guarantees your quarters will never get a window to let in the otherworldly light of Polyphemus.

“I was just wondering,” Jake starts, and you feel his swallow more than you see it, his Adam’s apple bobbing up and down in his throat. “If you’d ever wanna do… stuff… while I’m in my avatar."

The question takes you aback for a moment, stilling whatever gripe you had planned for him. As Grace’s trainee, it’s in your job description to help monitor and care for the avatars and their drivers, so it’s not like you’re unfamiliar with Jake’s alter ego. You helped grow the damn thing, watching over the huge blue body as it developed suspended in a tank of stasis fluid.

But you hardly ever get to see him in it. Jake’s almost always out in the forest with his avatar, roaming farther than Norm and Grace ever dare. You can’t say you blame him — if you had a shot at seeing Pandora through Na’vi eyes, you’d take it too — but it makes the thought of him with you in that alien body strange. Not just with you, but on you, inside you, big blue hands and striped skin and-

Jake must take your silence for refusal, because he begins to backpedal immediately.

“Forget it,” he starts, smoothing a hand down the curve of your spine like he can wipe away the offer. “I didn’t mean… well, I know it’d be weird-”

“Jake,” you cut him off, patting his chest. “I didn’t say no, dummy. Just- what made you think of that?”

Jake shrugs, shifting a little beneath you. He blows out a breath, and for a moment, his face twists into something you can’t read in the dark. A glimpse of what might be shame flashes across his features before he turns his head, hiding his expression from you.

“I don’t really get to do everything I want in this body,” he admits, his voice quiet, almost blending into the hum of Hell’s Gate’s constantly whirring generators. “The ways I wanna touch you, hold you… I can’t. But the avatar ain’t like that.”

“Oh.” The realization knocks something in your chest loose, rattling behind your ribcage. You wouldn’t change a thing about Jake, and his performance in bed has more than lived up to your expectations. You kinda like that he takes things slow, figuring out ways to make each touch feel good for the both of you. It makes him intentional, every skim of his fingers thought out for you.

But you didn’t realize what he’s been thinking of on the other end — all the other things he wants to do, things he probably hasn’t done since his service put him in that chair. You’d never ask Jake for more than what he can give, but if he wants to try this…

“Sure.”

Jake’s head jerks back towards you, like he’s a little surprised at how quickly you’ve agreed. His hand stills for a moment on your back, then tightens, wrapping around the dip of your waist.

“I don’t want you to agree ‘cause of guilt or something,” Jake starts, though you can already hear his heart pick up pace in his chest. “Y’know I don’t need pity-”

“I know that, dickhead,” You scold, prodding at his sternum so he quits. Of course he’s putting on the heroics about alien sex. “I wanna try. Might be weird, yeah, but…”

“But?”

You flush, ducking your head back into the cover of his chest. Jake curls to meet you, not letting you hide against the coarse hair there. He wheedles, bumping his nose along your forehead. “But?”

“But you look good as a Na’vi,” you admit, grumbling into his skin. “So tall, and those big eyes… those fangs…”

Jake laughs outright, the sound bubbling up through where you lay against him. You grouse, displeased at his sniggering. How did the tables turn from him apologizing to your embarrassment, exactly?

“That right?” Jake teases, pressing a kiss to your hair, sounding altogether too pleased with himself. “Have you been crushin’ on Na’vi, honey? I’m pretty big, I dunno if you can take all that…”

You scowl, offended at the implication. Squirming under the blankets, you poke sharply at Jake’s belly, reminding him exactly who he’s talking to.

“I take you all the time,” you rebuke, digging your chin into his chest in reprimand. “I can take your stupid avatar dick.”

The moment Jake undoes his loincloth, you realize you probably cannot, in fact, take his stupid avatar dick.

It’s been a few weeks since that late night discussion, long enough that you'd started to worry that you'd never get the chance to fulfill Jake's request. After all, it’s not really convenient to fuck an avatar. Not many places in Hell’s Gate are tall enough to fit a nine-foot tall alien body, while also being private enough to avoid a run-in with HR. Bright blue and huge, Jake’s not exactly inconspicuous.

You suggested just sneaking into the outdoor bunking unit, where the rest of the avatars sleep dreamlessly when they're not being piloted from the link pods. It's fairly reasonable, given it's within the compound and easily accessible to you. Jake's presence wouldn't be questioned, either, as long as he made up some excuse about not sleeping in Hometree for the night.

But you were both a little creeped out by the idea of fucking among the silently occupied bunks, surrounding yourself with the sleeping alien counterparts of your coworkers. Besides, there's no airlock in the avatar housing, and Jake insisted that he didn't want you to wear your exopack mask; at least not this time. While a part of you thrills at the implication of there being a next time with his avatar, it does significantly limit your options to indoor spaces only.

The lab works, but you’re never alone there. Grace and her underlings practically live in the place, buzzing in and out, always piloting their own avatars or monitoring the constant streams of new data and life you pick up from Pandora. With the scientist quarters close by, it’s hard to predict your coworkers' patterns, too — they work at odd times, kept up into the wee hours by shifts in the rainforest's atmosphere or detected pollution upticks near RDA factories.

But finally, you and Jake are alone, through no small effort; you've whiled away a significant amount of the evening waiting for the place to empty out. You had to make up a good reason to occupy the lab during its few empty hours, so you stayed under the pretense of checking the vitals of Jake's avatar, which he just couldn't drag back from his training in the forest until nightfall. The last stragglers went to bed a couple of hours ago, and the bags under their eyes implied a good long quiet period.

You're more nervous than you want to admit to yourself, shifting back and forth on your feet before Jake. Energy has been building up underneath your skin all day, apprehension thrumming under your skin as you tried to stay busy at your desk. It's made you jumpy, wondering if your coworkers can tell you're about to do something far and beyond inappropriate with one of the RDA's prized specimens.

Fucking Jake as a human has already earned you some criticism in the lab. In Hell's Gate, everyone is so close together that gossip spreads within seconds, and your peers knew about your relationship with him almost before you did. But while hooking up with the unpopular, intruding grunt has garnered a couple disapproving stares, you shudder to think what would happen if you're found out for having sex with his avatar. Technically, the body isn't Jake, only a suit on loan from the program. You can't imagine your higher-ups taking very kindly to you getting your hands all over it for purposes other than strictly research.

It's not like that's going to stop you, though. Not now, with Jake in his big, blue, alien body, grinning down at you like a predator tracking prey.

You swallow thickly as Jake’s loincloth drifts to the floor. It’s not like you haven’t seen his dick before. You watched that avatar grow, including all his reproductive functions. But you haven’t seen it since Jake inhabited that body, since it became more than just a lifeless science project floating in an oversized test tube.

“I assume you’re familiar?” Jake murmurs, taking himself in hand. Christ alive, he’s so big — you forget just how big his avatar is every time you see him. His head nearly brushes the lab ceiling, his yellow eyes reflecting faintly in the blue light of the lab screens.

It’s hard to keep your focus on him when you only reach about belly-button height, his crotch at eye-level. Your breath catches as your gaze flickers up to his face, then back down to his dick like a gravitational pull.

Something about his words snaps you out of it, and your eyes skitter away, like you’ve been caught staring. Your cheeks burn with sudden heat, a flush rising to your skin as you turn your face from Jake.

“Uhm… yeah, sorta,” you mumble, staring hard at the shining silver tubes that hook up to one of the avatar pods. “Wasn’t ever really my… focus…”

Jake raises his carbon dioxide respirator as he huffs out a laugh, the sound muffled by the breather. His chuckle is familiar in its teasing, though strange to hear from the mouth of such a different body. He squats, those long, muscular thighs bending easily to bring him down to your level.

One big hand reaches out, brushing gently against your neck. You try not to shrink under the warmth and weight of it, your heart skipping a beat. Jake’s fingers close gently around your chin, long enough to wrap around your entire jaw as he turns your face back to him.

“Come on then, kid,” he murmurs, inviting you in with a tilt to his head. “Get familiar.”

You’d love to flirt back, to sass him back with all the snarky banter you usually share. But the words escape you, every tease dying on your tongue. Nerves make your mouth dry, your tongue darting out to wet your lips.

Taking one tentative step forward, then another, you edge your way towards Jake. He watches you with a twinge of amusement, the corner of his lips drawing up into a smirk. The bastard thinks it's funny how nervous his new form makes you. You resist the urge to scowl at him, bolstering your courage to reach out and touch.

Jake’s half-hard already, and your breath catches as your fingers brush against him. The skin of his dick is hot, hotter than you remember his human erections being. Before you can lose your nerve, you wrap your fingers around his base.

He’s so big in your hand, bigger than you ever pictured in your head. It makes sense, logically — Jake’s over eight feet now, of course his genitals would grow to match — but somehow your brain stutters at the difference.

It’s a lot similar to his human cock, in most ways. The shape is almost the same, discounting the size difference; a long shaft, slightly thicker in the center, tapering into a mushroom head. It’s blue, just like the rest of his skin, and striped in the same tabby-like patterns. As you get closer to the tip, his shaft darkens into a deeper shade of blue, then fades to the same pink as his nose and tongue right at the slit.

Trails of dotted bioluminescence, like those that freckle his cheeks and chest, swirl down the skin of Jake’s dick. If you’re not mistaken, they pulse in time with the throb of his length in your hand.

You stare down at it, unsure for a moment what to do.

“You’re… pretty.” you mutter dumbly, eyes following down the twisting trails of glowing freckles. Like little constellations.

Jake barks out a laugh, and your eyes snap up to him, startled by the sudden sound. He grins down at you, his sharp incisors glinting in the light of a nearby monitor. Your cheeks burn hotter, and your gaze darts away again, overcome by the sheer size and strangeness of him.

“Easy, sweet girl,” Jake coos, tilting your head back to him again, his fingers applying gentle pressure to your neck. “It’s just me, alright? ‘S nothing to be scared of. I’m glad you think I’m pretty.”

You nod, eyes dipping from that steady yellow gaze to where Jake’s cock lays heavy in your palms. His words do something to soothe the ball of nerves that’s knotted up in your stomach, smooth some of the tension from your shoulders. It’s just Jake. Nine feet tall and bright blue and half-hard, maybe, but it’s Jake.

“Can I…?” You start, the murmur trailing off into the quiet beeps and pings of the surrounding lab equipment. It feels like the first time all over again, everything about his body strange and new and thrilling, even as it wracks your nerves.

Jake nods a little too quick, like he’s eager to get your hands on his body. “Yeah, yeah sweetheart, lemme just-"

His hand closes around your wrist, coaxing you to drop your grip on his shaft. For a second, Jake's ears flicker back like he misses the contact, but he's already moving, tugging you out of the lab's main circle of monitors and link pods.

Jake leads you to a familiar off-shoot from the main lab, the avatar physical therapy room. It's a good spot, and you wonder why you haven't thought of it before, given that it's suited to fit Jake's unique requirements. The ceilings here are high enough to accommodate the greater height of Na'vi bodies, the floors padded with soft mats for the comfort of the avatar drivers as they work out whatever injuries or soreness they encounter during their time in their alternate bodies. There's a air-locked door that leads straight to the outside portion of the compound, where the gardens lay, and past them the avatar bunking, so that the drivers can come and go as they please. The air index is set for human needs, given that the avatars are often accompanied by doctors walking them through exercises, but you could let in the Pandoran atmosphere if needed.

Jake's bare feet pad against the soft give of the floor mats as he leads you into the room, the low night-shift safety lights flickering on as you enter. Pulling you forward, Jake slides down to the mat with a thump, his tail curling to the side. He leans back against the wall, spreading his long, striped legs wide.

“C’mere,” he grunts, pulling you forward by your wrist. Jake brings you down to his lap, settling you onto one of his thighs, propped up against his chest. He’s warm, and so large and solid behind your back. You’re tempted to burrow into his side and hide away from how your heart is racing, but Jake’s got other plans. “There’s a better angle. Knock yourself out, honey.”

You swallow, staring down at his cock, bobbing expectantly between his legs. Your own thighs press together as you shift, a hot trickle desire starting somewhere deep in your gut.

Jake’s pillowed his head with his arms, elbows jutting out as he leans back against the wall to watch you. His pupils have blown a little wider, black swallowing up some of the feline gold of his iris. It makes you shiver, being watched so intently like this, with a gaze that’s somehow wilder, more predatory than when he’s human.

You pause when you reach for him, eyes alighting on a patch of black hair that nestles above Jake’s dick. It’s not like the pubic hair on his human body, which leads in from a happy trail and expands out over his inner thighs. Just a small bit of hair, just above his erection.

Frowning thoughtfully, you tip your head up to Jake. “Do all Na’vi have that, or is that an avatar trait, like your eyebrows?”

Jake raises an aforementioned brow at you, looking faintly amused. “I don’t know, clever girl. I haven’t really seen any Omatikayan guys whipping it out recently.”

Your cheeks go pink, and you duck your head. Right.

Jake doesn’t seem to mind being poked at like a science experiment, though, because he only chuckles, placing his palm on the back of your head. It’s heavy, his fingers long enough to splay from one ear to the other, like he’s cradling your entire skull.

“Keep goin’,” he encourages, threading his fingers into your hair. “It’s all yours.”

Warmth pools in your gut, and you can’t help the small smile the curls at the edges of your mouth. You hadn’t been sure about exploring Jake’s avatar, but the longer you look, the more you find that you want him.

Your enthusiasm is echoed in Jake, who keeps his eyes trained on every nervous shift you make. His sharp gaze doesn't leave you, even as he brings his respirator up to sip the air.

You press your side into Jake’s chest, leaning on him as support as you focus between his thighs. The hand he had resting on your head slips down, snaking around your waist to hold you steady. Jake must feel the shuddering breath you suck in when you take him into your hands again, fingers trembling with an electrifying mix of nerves and desire.

Using both hands now, you can feel more of him, the weight and heat of his erection. The first thing that strikes you is how soft Jake is. Not literally — he’s certainly well on his way to full-mast — but his skin. The planes of blue are silky, smoother and softer than human skin. Curious, you reach one hand to stroke down his stomach and find the same texture there.

Jake’s stomach muscles tense and relax under your touch, fluttering with the trail of your fingertips. On a whim, you brush your fingers back up his stomach, testing to see if he’s ticklish. You’re rewarded with a gruff laugh; a puff of amused air that ruffles the hair on top of your head.

“Gettin’ distracted?” Jake snickers, his tail flicking once behind him. You huff, the soft stroke of your fingers turning into a sharp jab as you prod at his stomach.

“Impatient,” You reprimand, though when you look up at him, Jake's grinning, completely unphased.

The hand around your waist tightens, his fingertips digging into the softness of your flank like a reminder. You roll your eyes at him, but obey nonetheless, sliding both palms back over his dick.

Running our fingers down Jake’s length, you notice that as he’s gotten harder ridges and bumps have raised along his length. They start at the base of his shaft, then lead down until they stop just before the flare of his tip, giving his dick a texture that’s far different from his human counterpart.

At first, you think they’re veins, thick and close to the surface. When you push your thumb down, testing them slightly, they don’t roll under the skin like a vein would, but instead keep their shape. You curl in a little closer, inspecting them with fascination.

They must be permanent ridges, natural raised twists that rib down his length. It almost puts you in mind of how a tree root gnarls, but it’s prettier than that, and more uniform, too. Each ridge is mirrored on the other side of his dick, creating a twining pattern. In passing, you wonder if the ridges are unique to each Na’vi male, but you’re quickly distracted by the thought of how that ribbing will feel rubbing against your insides. The notion makes you shudder, your thighs pressing together against the heat that grows there.

There’s an answering groan above you, and your eyes snap up to Jake, distracted for a moment. He’s stopped watching you, eyes closed, his head tipped back against the wall as your hands explore. Underneath you, his thigh is tense, the corded muscles tightening in reaction.

“Oh,” you breathe, looking down at where your thumbs press along two of his ridges. Curious, you slide the pads of your thumbs up the ribbing again, tracing the pattern with a firmer grip. “There?”

Jake’s hips jerk up once at the stimulation, thrusting his cock through your fingers. The movement jostles you, and your head snaps up, eyes fixed on Jake. He moans again, his brow wrinkling with effort.

“Yeah,” he grunts, his eyes opening to meet yours. With a touch of pride, you see his gaze has gone a little heavy-lidded, the rise and fall of his chest picking up speed. “Yeah, right there, baby.”

Sucking your bottom lip between your teeth, you readjust your grip, starting from the very base. He’s hard, and so hot under your hands, warmth that spreads into your palms. As you trace his ridges down to the very tip, Jake grunts under the attention. His fingers tighten at your waist, keeping you crushed close against him.

A dribble of precum leaks from his tip, beading at the sweet pink slit. At first, you think it’s only shining in the light of the lab’s running monitors, reflecting back the glow of the computers. But as you bend closer, you can see it’s got a luster of its own, glowing faintly in the dark. Like the bioluminescent freckles that are painted across his cheeks and legs and chest, his precum is phosphorescent, the light tinged with blue.

“Like little stars…” you murmur, recalling your thought from earlier as your eyes flicker between the dots on his shaft and inner thighs, then back to his pretty precum. You’re close enough now that your warm breath washes over Jake’s cockhead, and he jolts at the feeling, dick twitching up on its own.

“Glad you like it,” Jake says, but he’s goading you through gritted teeth. Obviously, letting you play with his cock is working him up more than he cares to admit. He rocks his hips up into your hands, dragging the hot weight of his dick through where your palms cup him. "How 'bout some hands-on appreciation?"

You roll your eyes at him despite yourself. Experimentally, you pump him once, using both hands and twisting slightly at the tip, the way you know he likes as a human. Jake’s snarking cuts off quickly, and he groans, his leg tensing underneath you. “Fuck, baby..”

Emboldened by his reaction, you swipe your thumb over his tip. A bead of precum comes away on the pad of your thumb, and you hold it up to your face. It keeps its iridescence, glowing faintly against your skin.

You look up at Jake, and find him already watching you, his eyes wide. Behind him, Jake's tail lashes, thumping enthusiastically against the floor mat. If you weren't feeling so worked up yourself, you'd crack a joke about his dogged eagerness, but you're already antsy yourself.

Slowly, making sure his eyes are still on you, you raise the pad of your thumb to your mouth and lick.

There’s hardly enough to get a real taste, but what you can savor is surprisingly pleasant. Jake’s precum isn’t salty or bitter like a human’s, though it still has that undercurrent of musk; it's earthier, almost aromatic.

Beside you, Jake lets out a shaky exhale, his chest dipping. You can feel his cock jump, twitching against your thigh, and it sends of a jolt of heat between your legs.

“Goddamn,” he hisses, his voice hoarse. “You’re drivin’ me up the wall, sweetheart. Are you about done exploring?”

You swallow thickly, your hand dropping away from your lips. Done implies moving on to the next step, something you’re not quite sure of. All of the bravado you’ve built up playing with Jake’s dick leaves you, the little ball of nerves tightening in your stomach.

“I- I guess so,” you mutter, ducking your head under his chin. You suck your bottom lip between your teeth, chewing on it uncertainly. It’s not as if sex with Jake is an unfamiliar thing. But this, sitting on the lap of a giant blue alien, is far beyond your realm of expertise. It’s a little ridiculous, given that it’s part of your job description to study his biology, but the newness of it all makes you skittish.

Jake’s hand slides up from your side, smoothing over your upper back. It’s a soothing touch, and he leans down to where you’re curled into his side, still propped up on his thigh.

“Second thoughts, honey?” he asks, nuzzling his face into your hair. Jake’s nose is flatter now, sloping down into a blunt feline tip, and he presses it against the top of your head. The sensation reminds you of a huge cat, nudging into your face for attention.

“No,” you start, though your voice pitches higher at the end of the word. You try again, swallowing down the dryness in your throat. “No, I just…”

You stare down at his cock, bobbing expectantly against his stomach. You want to touch it more, you do. You’ve already grown slick between your thighs, and every time your legs clench, the pressure sends a little ripple of pleasure up into your gut. But…

"I don’t really know what to do,” you whisper. A little humiliated at the confession, you tuck your head into Jake’s chest, cheeks burning. His hand slows on your back, long fingers resting lightly on your spine. “I mean, I know, but I…”

Jake shushes you, cooing softly into your ear. His breath ghosts over your cheek, warm and close and rumbling. With a rush of affection, you realize he's purring like a loved-up feline, the vibrations reverberating through his chest and into you. It's a surprisingly charming sensation, almost ticklish.

“S’okay, honey. I’ve got plenty of ideas on what I wanna do to you,” Jake promises, and the rumble of his voice so close makes you shudder. “Let me take care of it.”

You find yourself nodding against his chest, relief smoothing out some of the tension in your shoulders. Desire pools in your gut, and you slide your thighs together instinctively. You’d almost forgotten the whole reason Jake had initiated this was to fuck you in ways he couldn’t in his human body. Whatever he’s about to do, he must have been thinking about it for a while, and the prospect has your stomach tightening pleasantly.

Jake takes his cue, and the hand he had stroking down your spine shifts, wrapping tightly around your waist. He hauls you up off of his thigh, the movement startling a little gasp out of you. Jake’s always been strong, but he moves you so easily now, manhandling you like nothing more than a doll.

He sets you back in his lap, facing his front now. Coaxing you to his chest, Jake moves so your knees bracket his hips, forcing your thighs apart, and you flush, feeling exposed.

If Jake notices your embarrassment, he doesn't bother to pay it any mind, already tugging at the hem of your shirt. His knuckles brush against the bare skin of your ribs as he makes an impatient noise, itching to get you undressed. "C'mon, kid, don't make me wait."

You laugh at his eagerness, but help him regardless, lifting your arms over your head so he can pull the fabric up and off. The shirt is instantly discarded, tossed carelessly across the PT room. Your bra doesn't survive much longer, Jake reaching behind you with practiced familiarity to undo it. To give him credit, you're a little surprised his new big fingers are nimble enough to unhook the clasps.

Jake sucks in a breath the moment your chest is bare, his tail giving a harsh thwack against the wall. Reading Jake's familiar expressions in an avatar's face is novel to you, and you're not quite sure that you've got every cue down, but the look he's got now is unmistakable. His eyes round into wide, excited circles, his pointed ears perking up and swiveling towards you, pricked for the sound of your breathing, drinking in the way the hush of air matches the rise and fall of your bare breasts.

Jake is hungry, his eyes greedy as they rove across your naked skin.

He doesn't bother asking for permission — your body is far more familiar to him than his avatar is to you, after all — a huge blue hand coming up to cup one of your tits. You let out a soft noise of gratification as he kneads at the soft flesh, making Jake's ears twitch. His hands are calloused, much like they are in his human body, palms rough from weeks of training in the forest, toughened by constant climbing and shooting his bow.

Unlike his human hands, though, is the sheer size of him. Jake's palm is big enough to cover almost the entirety of your breast as he fondles you, oversized fingertips pressing firmly into the suppleness. His other hand slides behind your back, forearm bracing behind you to keep you in a steady hold.

"Gotta get my mouth on these," Jake rumbles, ducking his head to do just that. He presses kisses to the top of your tit, then down the valley between the swell of your breasts. Every brush of his lips against your skin seems to tingle, and when he drags a fang lightly down the curve of your underboob, you shiver. Jake looks up at you at he works, taking in the fluttering of your eyelashes with a smug smirk.

"You've got such pretty tits, baby," he praises, lips hot against your sensitive skin. His tail undulates slowly behind him, flicking in satisfaction. "My perfect woman."

You hum, head tilted down to watch him. Jake's back is curved low to burrow into your breasts, and you slide your hands off of his shoulders to feel how the muscles of his chest flex in this position. Patting at his pectorals, you grin.

"You're not so bad yourself, Sully."

"Gee, thanks." Jake sniggers wryly. "You're a real charmer, aren'tcha?

You huff a little laugh at that, but the giggle quickly cuts into a groan as Jake finally brings his attention to your nipple, licking a warm stripe over the budded peak. He's quick to repeat the motion, the broad, flat plane of his tongue rasping over the nub again and again. The feeling of his avatar's tongue is unlike anything you've experienced before, hot and soft, but almost barbed, catching at little on your skin. It's addictive, and you push your chest up into Jake's mouth without thinking about it.

Jake growls in approval, parting his lips to suck your nipple into his mouth. A soft sigh slips from your lips as he suckles, the pressure sweet and sating. It stokes the pleasure in your gut, heat flaring low in your tummy. You can already feel how slick you're getting, the wetness between your legs growing from the way your thighs are stretched open over Jake's hips and the attention he's lavishing on your chest.

"Jake…" you murmur, hand coming up to rake through his hair. He's changed it some since he started training with the Omatikaya, little black braids hanging down in front of his ears where he used to let it hang loose. When he doesn't look up, too busy mouthing at your tits, you tug lightly on one of his braids.

Jake's eyes flick up to yours, and he grins around your nipple, lips curving against the swell of your breast. His smirk is far too pleased, especially for a man who's currently suckling needily at your bosom.

"Impatient," he smirks, echoing your earlier tease. His mouth pops off of your tit, leaving the rosy nub wet and peaked. Jake's tongue swipes over his lips, a flash of fang glowing white in the PT room's low light. "Why can't you just take what I give you, huh?"

You scowl at him, squirming in his lap to scoot yourself further up his thighs. He's being such a dick, teasing you like this when he knows you've been getting worked up over this for weeks. First and foremost, you've been worried about getting caught, but underneath that worry, there's been a growing thrill about how new all of this is going to be. While it's still Jake underneath all that muscle and sinew and prehensile tail, the fact that his alien body is strikingly different is undeniable.

Will you even be able to fit him? You're dubiously uncertain, given the new size difference between the two of you. Maybe you ought to have a less tentative grasp on the concept, given it's your job to study avatar biology, but the thought of applying those theories to your own body is daunting. It's not like Na'vi/human sexual explorations are catalogued research, after all.

You want to find out, though, and Jake is taking forever to get there.

"You're going so slow," you grumble, pulling insistently on his braid again. You roll your hips down experimentally, trying to get some friction from where you're straddling Jake's hard-on. The pressure is good, but your pants and underwear block any real progress, and you whine. "Come on, Jake."

Jake only smirks, grabbing ahold of your hips. He stops your movements easily, thumbs pressing hard against the jut of your hipbones as he halts your grinding.

"Quit whining," he snickers, leaning in to nip at the tender skin at the corner of your jaw. "I've gotta get you ready; you're so small. Don't wanna hurt you."

You huff, rolling your eyes. In theory, you know it's because Jake really does care about you, doesn't want to damage anything in his eagerness with this big, brawny new body. But there's an undertone to his voice that's smug, a little tilt to his mouth that tells you exactly how pleased with himself he truly is. Like he's fooling anyone — you can feel his erection pressed to your thigh, hot and heavy.

"You're just being a dick and drawing this out to make me squirm."

Jake doesn't deny it, the corners of his big, yellow-green eyes crinkling up. "It's working, isn't it?"

Leveling him with a glare, you reach up and flick at one of his pointed ears. "At least get me naked, Sully."

Jake's got no protests for that particular order, only grinning ferally as he wraps his hands back around your waist. With a grunt, he hoists you up off of his lap, giving you enough room to shimmy out of your pants. The fabric bunches around your ankles as you struggle to kick it off, and Jake tugs them off fully with an impatient jerk. They're discarded just like your other clothes were — tossed to some dark corner of the PT room without a thought.

When it gets to your panties, though, Jake gives pause. You're already starting to draw them down, but Jake's palm presses against your fingers, stopping your fingers where they're wrapped around the waistband.

It's a lacy little pair, something cute you dug up from the corners of your military-standard wardrobe. Jake slips a finger under the elastic, pulling it forward and let it snap back to your skin. You give a little yelp, then glare at him, but he's not paying your complaint much mind at all, too entranced by the slope of your cunt under the sheer fabric.

"Cute," he croons, swiping a thumb across where one of the straps arcs up over your hip. You're slightly mollified by the attention. You have put thought into this, after all, given how important it seemed to Jake when he first brought it up. You went to the trouble of finding a matching set and everything, though Jake hadn't really noticed the details of your bra in his eagerness to get to your tits.

Jake's eyes flicker back up to you, his tongue darting out to draw across the tip of one of his fangs. The grin he gives you is wolfish, pleased with your little performance. "You dressed up for me?"

You can't help but smile back, cheeks heating under his stare. "You like it?"

Jake's eyes slide back down to the curve of your pubic bone, his finger tracing along the waistband to the front of your panties. He twiddles with the tiny bow that's sewn to the front, a purr reverberating up from his chest.

"'Course I do. Pretty things for my pretty girl."

You wiggle in Jake's lap, shifting your weight across the striped blue skin of his thighs. It's a bit of a novelty for you to be able to prop yourself up like this across his legs, to find warm muscle underneath you. Jake doesn't bother to correct your movement this time, just running a teasing fingertip down to where the fabric of your panties cuts into the flesh of your ass.

"Yeah, well, I thought we could match," you quip, reaching for the respirator mask slung around Jake's neck. He breathes in obediently when you lift it to his mouth, like he'd forgotten it was there entirely in favor of savoring your newly-bared skin. "You're the one who showed up in just a thong, remember?"

Jake barks a laugh, his expression twitching into something wry. He bats away the respirator, nose crinkling at you in a play at indignation.

"Smartass," he says, voice warm with affection. "Didn't hear you complaining about my tewng earlier."

It's true — when you'd radioed Jake earlier this evening, whispering to him over comms that the lab was clear, you hadn't been prepared to see him pop up in all of his loincloth-clad glory. As much as you like the human Jake, with his worn band t-shirts and Marine Corps hoodies, you have to admit that going Na'vi was a good look for him. He hasn't earned his cummerbund yet, so his attire is simple; a leather loincloth of animal hide that hangs low around his hips, his knife sheath, and a few woven armbands twined around his biceps, highlighting the muscle there. He'd flexed, smirking at you. "Fashionable, huh?"

You can't deny it, so you just scrunch your nose at him, annoyed at being called out. "Whatever. Not my fault you look good in your little Na'vi panties."

Chuckling, Jake just palms your ass, giving the soft flesh a firm squeeze in retribution. He's not going to waste more time squabbling with you, not when there's so much more he wants to do with you tonight, finally getting what he wants in this better body. Especially not when you're in his lap, pretty and flushed and smelling so good.

Jake ducks his head, shoulders curling down so he can press his face against your ribs. He takes a deep inhale, his nostrils flaring as he sucks in a lungful of air. When his eyes open, darting to your face, and then back down to your cunt, Jake's pupils have blown wide.

"Fuck," he groans, ears pinning straight back to his skull. "Fuck, mama, I gotta-"

Whatever he's gotta do is lost on you as Jake moves swiftly, heaving you up and off his lap. You squeak in surprise as Jake plops you back down on the ground, one big hand pushing your chest down, forcing you to lay flat. You go down hard enough to leave you winded, breath forced out of you in a puff.

"Jake-" you start to protest, struggling to your elbows, but he silences you with a firm palm on your stomach, keeping you pinned down.

"Quiet," he murmurs, shifting to his knees as he crawls towards you, pushing his head up between your legs. "Just be still."

Swallowing hard, your throat clicks as you comply, suddenly lost for words. Jake's shoulders are so broad, forcing your thighs open with ease. Not for the first time tonight, you feel as though you're spread wide open for him, bared for those big yellow eyes. The damp patch that's been growing on the crotch of your underwear feels cold suddenly, exposed to the conditioned air.

Jake keeps his hand steady on your stomach as he leans in, nose bumping up along your pelvis. His breath ghosts hot and close over the wet fabric, making your legs jerk instinctively closer around his head. He doesn't even bother to tease you, too busy worming his way in deeper between your legs.

It's not until he pushes the blunt tip of his nose directly against your crotch and snuffles that you realize what he's doing.

"Jake!" You squawk in protest, then clap your hand over your mouth, looking around the darkened lab like Grace is going to coming flying around the corner at any minute, HR violation paperwork in hand. When none of your coworkers appear outside the glass doorway of the PT room to investigate your noise, you turn your gaze back on Jake, eyes wide.

He's still totally engrossed between your legs, sucking in big breaths through his nostrils. There's absolutely nothing repentant about the way he nuzzles at the crux of your thighs, sniffing enthusiastically at your underwear, nose pressing against where your panties stick to your slick folds.

You squeeze your thighs around his big, dumb, blue head, trying to ward him off, but Jake only grunts, your effort completely lost on him. Damn him, and damn this size difference.

"Stop smelling me," you whisper furiously, still a little paranoid in the quiet of the PT room. "What the fuck is wrong with you?"

Jake pauses in his sniffing long enough to grin up at you, running the hand that's not pinning you down up the inside of your thigh, callouses brushing over your skin. He uses it to coax your legs apart again, urging you to open up around his head.

"Can't help it," he purrs, ears twitching against the sensitive skin of your inner thigh, the tips ticklish. "I've been smelling you all night. Didn't even realize it was you, 'til I got those stupid pants off. Thought it was just some new perfume."

That's new.

Of course, you'd both known that Jake's senses would be heightened in his avatar, scent and taste and touch beyond human experience. He can even see better than you right now, his gold-green eyes so much larger than yours, pupils expanded to suck in every trace of light in the dark.

Even with the weeks he's spent training with Neytiri, Jake's not completely used to this new body he gets to pilot. In his avatar, everything seems ramped up by a tenfold, his eyes and ears and nose so much more responsive than anything he's felt as a human. Parts of his body behave in strange ways, often against his bidding; his ears pricking high and forward when he's interested, pinning back when he's scolded, or his new tail always thrashing around with a mind of it's own.

You like Jake's new little tells, truth be told. He's not the type of guy who makes too much of a fuss about expressing his own emotions, often leaving you to pick up on his feelings from the little half-glances and cocked smiles he sends your way. But in his avatar, Jake doesn't have as much reign on his reactions. Every expression is bigger, bolder, harder to control, and while it frustrates Jake, you find it sweet. You can tell how he's feeling even if he's clumsily attempting to hide it, betrayed by his overactive tail and swiveling ears and cute sloped nose.

Somehow, though, you hadn't thought about Jake's new sensitivities exposing anything about you. It makes you blush, embarrassed at the thought of your own neediness being so obvious that he could smell it.

If you think about it, though, it makes sense that he can pick up on the scent of the arousal that's growing between your legs, sexed up enough to wet the crotch of your panties. And there's probably a biological reason why he'd be so attracted to the smell of a female ready to mate, though it's fascinating that that reaction applies to humans as well, not just Na'vi women. Is it because he's an avatar, his human DNA affecting his perception? Or perhaps he's subconsciously adjusted to your pheromones, given your established relationship? Shit, you'd really, really like to write this down-

Jake rudely interrupts your train of thought by licking over the damp spot on your panties, pressing the flat of his large tongue against the fabric. You jump, a surprised gasp tearing out of your throat at the wet pressure. Jake laughs into your cunt, the sound muffled against your underwear. A part of you wants to grind down into his tongue, seek out his mouth through the cloth, but your dignity is still smarting.

"You could smell me this whole time?" you ask, peering down at Jake between your legs. Heat rises to your cheeks as Jake pulls his head away from your crotch, leaning his cheek up against the pillow of your thigh. His nostrils are still flared, his breath a little too deep to be innocuous.

"Yeah, of course," he says casually, like he isn't telling you that your pussy stinks. He catches your sour look and smirks, his huge hands sliding down from your stomach to grasp onto your thighs. He squeezes the meat of your legs. "Relax, it's a compliment. It smells… sweet."

You suck your lower lip into your mouth, gnawing on it uncertainly. It's a new concept, and a slightly embarrassing one, but you can't accuse Jake of lying about how much he likes it. His tail waves enthusiastically behind him, and his eyes are earnest as he looks up at you.

"I promise, you smell good," Jake assures. His head dips down again, groaning as he inhales. "Shit, it's so good."

"This is weird," you complain, shoving his head back with the heel of your palm. "You're weird, Sully."

Jake huffs, pressing his forehead back insistently into your hand. "Sex with an alien, baby. What'd you expect?"

Fair point. You could argue the semantics on whether Jake actually counts as an alien, since he's technically human in everything but body. But his breath is puffing hot across the apex of your thighs, stirring the fine hair there, and the wet spot on your panties is starting to bother you.

"Did you set this up just to sniff me, then?" you challenge, narrowing your eyes as you look down at Jake. He grins, flashing you his sizable canines, like he thought you'd never ask.

"No," he murmurs, nosing in to give the crotch of your panties a quick kiss. "I didn't."

He gives your thighs another squeeze, fingertips pressing in hard before he slides his hands up to the lacy straps of your underwear. Hooking his fingers under, he pulls your panties down over the slope of your hips, guiding them off your ankles and throwing them with the rest of your clothes.

Jake nestles between your legs, settling there like he's got every right to take up the space. Laying flat on his tummy, he grabs your thighs and hoists them up over his freakishly broad shoulders, forcing a little squeak out of your mouth.

For a moment, he just gazes down at the slickness of your cunt, looking impossibly smug, like he's proud of how wet he's gotten you. You squirm under the attention, kicking your feet against the strong planes of his back. "Jesus, Jake, stop staring-"

A moan interrupts your tirade, tearing from your chest as Jake finally puts his mouth on you. He licks a broad stripe from your dripping hole all the way up to your clit, parting your folds around the firm muscle of his tongue.

If you'd thought the barbed texture of his tongue had been good while he'd been mouthing at your tits, it's even better against your pussy. Every lap drags a little at the hyper-sensitive skin, forcing your legs to twitch around his head as your gasp.

And Jesus, his tongue is so big, nearly able to cover your entire cunt when he opens wide. When Jake flattens it, you can feel the wet heat all the way from your swollen clit down to your entrance, like he could suck all of you into his mouth.

Now that Jake's finally decided to touch you, he's eating you out in earnest, licking and suckling and biting. He's already got an arsenal of tricks up his sleeve, given the amount of times you've done this before, little things he knows get you off. Usually, he takes longer teasing you, kissing and nipping at your pussy lips to work you up, but he's too eager tonight.

Jake's eyes are wide open as he buries his face in your pussy, huge and yellow like pretty twin moons, watching you from between your legs. The intensity of his gaze, paired with the pressure of his nose bumping against your clit as he curls his tongue into your hole, is enough to get your chest heaving.

You hide your face in your hands, overwhelmed by the barbed rasp of his tongue and the sight of his mouth working eagerly. Pleasure is coiling up in your gut embarrassingly fast, snapping taut like a cable. You're just starting to rock into his mouth, fingers pressed over your eyes, when Jake lifts his lips away from your cunt. Snapped from your haze, you whine with the sudden loss and peek out from between your fingers to look at him.

Jake's eyebrows are knitted as reaches up to your face, snagging both of your wrists in one large, striped hand. He yanks your fingers away with a frown, the lower half of his face wet with your slick.

"Eyes on me, pretty," he complains, nipping at the fat of your inner thigh in reprimand. He's careful not to let his fangs draw blood, but when he sucks a mark on top of the indents of his teeth, you know he's intent on leaving a bruise. "I wanna see."

"Okay, okay," you nod, your movements jerky and impatient as Jake's teeth worry at your delicate skin. Your hips twitch around his head in a silent plea, and he finally unlatches, pressing a hasty kiss to the hickey he's left before he's devouring you again.

Your hips cant up, trying to grind against his face, and Jake purrs in satisfaction, the vibration rumbling through his lips into you, shooting up your stomach. It makes you cry out, over and over, breathy little mewls that you try and fail to hold in. You don't know exactly how loud you're being in quiet darkness of the PT room, sound muffled by the blood that's rushing in your ears, but you know you're not being quiet.

Jake doesn't seem to mind at all, his pointed ears swiveling forward every time he makes you gasp or moan. It tickles against the skin of your inner thighs, making a delirious giggle bubble out of your chest. Jake looks up at the sound of your breathless laughter, grinning against your folds, his tail giving a happy beat against the matted floor.

"Feels good, baby?" he asks, pulling away for a moment. He presses a kiss to the curve of your pubic mound, lips soft against the tender skin.

"Uh-huh," you mumble, already starting to feel dazed just from his mouth. You dig your ankles into his back, pressing against his shoulder blades to urge him back between your legs. "Your giant tongue is fuckin' awesome."

Jake rolls his eyes at you, his hands squeezing at your hips reflexively. He releases his grip on you for a moment, snagging his respirator from where it hangs around his neck and bringing it up to his mouth. "Idiot."

You only grin, pushing yourself up higher on your elbows to get a better look at him as he sucks in a couple breaths. He's so pretty, his avatar attractive in a way you didn't expect. Honestly, you only regarded his other body with curiosity before he suggested fucking you with it, but now that you're actually doing the damn thing, you can't deny the appeal. Of course, it's helped by the fact that he's currently got his head burrowed between your legs.

"You ready for a little more?" Jake asks, letting the mask fall back to his chest. His hands return to your thighs, fingers nearly long enough to wrap around your entire leg.

You nod, swallowing thickly. Some of your confidence has worked up since Jake first pulled out his dick, and while the logistics of actually putting that thing inside you are still a little baffling, your curiosity outweighs your trepidation.

Jake hums in approval as he lowers his lips back to your cunt, the vibrations sending a pleasant shiver up your spine. He points his tongue to swirl little circles around your clit, and you suck in a harsh breath, heat shooting down from your gut to the tips of your toes.

With one hand, Jake pushes your thighs farther apart, breaking the cocoon they've made around his head, and with the other, he traces a finger around your hole. You bite your lip, resisting the urge to keen as you rock your hips up into his hand, begging for more.

When Jake finally pushes his finger in, it rips a moan from your throat, the sound wanton as he sinks his digit in up to the knuckle. You're more than wet enough, slick with your arousal and his spit, but the stretch is still a surprise. His hands are much larger now, and it feels like you've got two fingers inside you instead of just the one.

Jake crooks his finger inside you, prodding gently at the soft squishiness of your inner walls. He can reach a little further inside you now, and his touch is exploratory as he keeps his mouth busy at your clit, lapping dutifully.

You groan, eyes slipping shut again as Jake works his finger in and out, building up a nice little rhythm. He matches every thrust of his finger with a swipe of his tongue, coaxing soft mewls out from your chest.

You're unprepared for the second finger Jake adds, and your eyes fly open, gasping from the sting of the stretch.

"Shit — Jake!" you yelp, hands scrabbling to get a hold in his hair. Two of his fingers together are thick, and tears prick at the corner of your eyes as he worms himself in. Your hips jerk at the pressure, like your body's not quite sure if it wants to run away or seek him out.

"So whiny," Jake murmurs, his other hand gripping tighter onto your thigh, forcing you still. "You can take this, kid, no problem."

You can take it, but it doesn't stop you from tugging on his hair in revenge. Jake grumbles, nipping at your clit, the sharp point of his fangs making you clench down hard around his fingers with a gasp.

Jake works you slow, driving his fingers in unhurried and measured. You start to relax again, body sucking him in eagerly now as the burn fades to sating fullness. Wet noises squelch between you, loud enough in the quiet of the sleeping lab to make you blush.

The fist you had in his hair gentles, petting down his head as it bobs between your thighs. Your fingers card through Jake's soft black hair, eyes catching on the thick braid that snakes down his back, protecting his neural queue. You know the Na'vi use their kurus for connection when they're mating — you can't link up to Jake, but you wonder if playing with it a little could get him off, too.

You tamp down on the urge to reach for it and find out, not wanting to interrupt Jake when his tongue is flicking just right. Maybe next time, you think, and the coil of heat inside you only grows at the thought of next time.

Your interest is quickly reverted as Jake's long, prodding fingers find a familiar notch inside you. A thrill races through your stomach as he presses there, his eyes meeting yours in a question for approval.

"Oh, God," you groan, biting down on your bottom lip. You worry it between your teeth, brow drawing down in concentrated pleasure. "Right there, Sully-"

Without missing a beat, Jake returns to it, rubbing hard against the softness of your walls. Ecstasy rocks through you as you grind down onto his fingers, your body shuddering in pleasure. Jake moans in response, his tail undulating eagerly and flicking across the bottoms of your feet where they're thrown over his shoulders.

Heat is building up quick in your gut now, amplifying with every crook of Jake's fingertips. He switches from flicking his barbed tongue across your clit, wrapping his lips around the sensitive bud instead and suckling. You cry out, your hand tightening in his hair as you grow closer and closer to the edge.

"Jake- Jake, I'm close-" you pant, humping your hips against his face as he works his fingers in and out. His elbow knocks against your knee as he thrusts, but you can hardly feel it, every nerve in your body seeming to condense in your cunt.

"C'mon, give it to me," Jake mumbles, words sloppy and muffled by your pussy. "Give it to me, pretty." The reverberations have you reaching a little higher, chest heaving for breath as your face screws up.

Your legs lock up around Jake's head, crushing tight around his jaw as you start to tip over. He hardly seems to notice, giving a particularly harsh suck to your clit as he drives his fingers home one more time.

"I'm gonna- I'm gonna-"

Your orgasm crashes over you like a wave, the heat that's been pooling in your gut spilling over all at once. A soft cry tears from your throat as the pleasure blinds you, your thighs shaking around Jake's head, your hole clenching hard and hungry around his fingers.

Jake doesn't stop, just keeps working you through your climax, the soft plap of his fingers barely legible through the buzzing in your ears. Your pussy flutters around him, walls pulsing as you come down from your high.

He scissors his fingers inside you, just to stretch you out a little bit more for good measure, and doesn't quit till you're smacking at his chest, whining from overstimulation. Only then does Jake lift his head from your cunt, his satisfied smile wet with his salvia and your juices.

"Enjoy yourself?" he teases, pulling his fingers out from your hole. Your breath catches at the loss, coming quick and uneven from your orgasm.

"Asshole," you complain weakly, pushing on his collarbone. Your tiny human hand does nothing to budge him, and you sigh. "Yes."

Jake purrs, crawling up over your body to see you eye-to-eye. You lie bonelessly beneath him as he holds himself up on his forearms, your body turned to a pleasant mush. It feels like all the warmth that had built up in your stomach has spread out through your body, making your fingers and toes and head feel fuzzy and warm.

Jake dips his head down for a kiss, and you accept him easily, opening up to let him slot his lips over yours. His tongue feels just as big in your mouth as it did on your pussy, licking the backs of your teeth as he makes you taste yourself.

When he finally breaks away, Jake presses a sloppy kiss to the corner of your mouth, then another to your cheek. He trails across your face, rubbing his mouth and chin over your skin, his chest still rumbling in that proud purr. The spit and slick that wet his lips get smeared over your skin, and you scrunch your face up at him.

"Ew, Jake. You're making me all gross."

"You're already gross," Jake snarks, prodding you in the side with one of his fingers, still slippery with your juices. You scowl, twisting and turning underneath him to get away from his poking. It's futile, and Jake's already smushing his face against yours again, his nose pressing into your cheek. "This is all you, baby."

Jake's clearly enjoying how small you are underneath him, pinned in easily by his big warm body and unable to shove him off. Ignoring your protest, he just keeps nosing at you, rubbing his cheek over your jaw, inhaling deep at the crook of your neck.

You grumble something incoherent, but your post-orgasm bliss makes it hard to hold onto any irritation. Stretching your legs out until your toes tremble, you yawn underneath Jake, basking in the gratifying afterglow of a good climax.

The soft rush of breath ruffles Jake's hair, and he looks up from where he's been nuzzling insistently into your collarbone, the corner of his mouth quirked up.

"Tired already?" he goads, sitting up above you to give himself more room. Settling back onto his haunches, Jake keeps his eyes trained on you, drinking in the sight of you shifting and stretching lazily on the PT mats.

"Whatever," you say, cupping a hand in front of your mouth as another yawn wracks through your body. Jake just snickers, shifting to scoot back and widen his thighs.

"You're not done yet," he reminds you, reaching between his legs. Your gaze follows the movement, chest tightening a fraction as you watch him wrap a hand around the base of his cock.

"Oh," you breathe, the words coming out in a wheeze. "Right."

Between your fascinated curiosity about Jake's pretty alien avatar and the way he'd curled his tongue up your cunt, you'd gotten a little distracted from the original reason behind this whole illicit lab escapade. The ways he wanted to hold you, touch you, fuck you, that weren't possible with the handicaps of his human body.

Jake's laughing at how your eyes have widened, your fuzzy post-climax brain slow on the uptake. His grin only broadens as he pumps himself lazily, your eyes glued to his dick.

"What's wrong, pretty girl?" he coos, schooling his expression into mock-sympathy. "Nervous?"

"No," you insist, trying to force the waver out of your voice and sound snappish instead. You clamber up onto your elbows, glancing between Jake and his hips rocking up into his fist. "No, it's just-"

You turn your head away from him, trying to hide your cheeks glowing red. No human would be able to see it in the dark, but Jake's got better eyes now, and he always has a good read on you anyways. "You're just so big."

That earns you a delighted croon, Jake's tail swishing excitedly behind him as you stroke his ego. You face him again if only to glower at him, trying very hard to keep your eyes off the way his cock is still wrapped up in his fingers.

"Don't get a big head, Sully, I'm just talking about it logically," you snort, heaving yourself up to sit with a huff. You cross your arms over your bare chest as if to suppress the anticipation that's building behind your ribs. "Do you really think you can make it fit?"

The damage is already done from your compliment, because Jake's smirk doesn't drop. He'll be riding the high of 'you're so big' for a while, but he puts aside his ego for a moment to address your concern.

Dropping his grip around his base, he reaches out and snags you by the ankles instead, yanking you closer to him. You squawk in surprise, falling back on your butt as he drags you in by your legs. Thank God for the thick walls of the lab, because you've made a lot more noise than you planned to tonight, and Jake hasn't even started having his way with you.

Jake bullies his way between your legs for the second time tonight, hooking your calves up over his thighs and settling back on his haunches. He keeps his hands on the inside of your knees, palms warm against the skin as he spreads you out.

"Mmm…" Jake hums thoughtfully, squinting down at your pussy with an appraising eye. Embarrassment and indignation rise up in your chest, heating your face, and you squirm, trying to close your legs.

Jake doesn't let you, his hands holding firm on your knees, keeping your thighs bracketing either side of his waist. He leans in, hot breath washing over your clit, still sensitive from the orgasm he gave you a couple minutes prior.

"It'll fit," Jake declares, like he's been prospecting schematics instead of going eye to eye with your hole. "Maybe not all of it, but enough."

"Reassuring," you deadpan, squeezing your thighs around his waist. Jake rolls his eyes at you, letting go of one of your legs to flick you in the forehead.

"Thought you wanted this," he says, raising one of his dark eyebrows at you. One of those little human traits that carried over into his avatar, a bit of familiarity in the alienness. "Don't you wanna fuck a Na'vi, baby? You were all excited about my eyes and my fangs-"

You groan as Jake parrots your earlier words back to you, waving him off with a flustered hand. "Whatever, whatever! Let's just- let's just do it. Just… be nice, alright?"

Jake tilts his head as he looks down at you, trying to hide a smile. "I'm always nice."

"You know what I mean," you start, watching as he draws back to take himself in hand again, positioning his hips better between your legs. "I'm just no-"

You cut yourself off with a stuttering gasp as Jake guides his cock to your cunt, his blunt tip parting your folds. He doesn't push in yet, just drags his cockhead through the wetness, coating himself in your slick.

"Fuck," you groan, your head tipping back as his tip rolls over the bead of your clit, the pressure making stars burst behind your eyelids. "Fuck, Sully…"

Taking advantage of your neck being bared, Jake shuffles over you, keeping one hand on his cock while the other plants beside your head. He presses open-mouthed kisses across the line of your jaw, trailing down to where your throat works as you try to hold back a moan.

"Won't hurt you," Jake promises, the words mumbled into your skin as he keeps guiding his tip up and down over your clit, the blunt pressure making your nerves sing. "Gonna make you feel so good, sweetheart."

You whine in agreement, the noise coming out high-pitched and needy. Jake takes it for the invitation it is, adjusting his grip to slot his cockhead right over your entrance, lined up to breech you.

Your hole sucks greedily at his tip, already warm and wet around him. Jake grunts, his mouth falling opening against your neck, and he suckles another mark there, his tongue hot on your skin. It feels like your pulse rises up beneath the skin to meet him, heartbeat thrumming under his lips.

Slowly, Jake pushes in, sinking the flared tip into your pussy with a throaty groan of relief. Underneath him, your back arches on instinct, a choked, surprised noise falling from your lips. You're wet and you're loose from the earlier fingerfucking, but Jake is huge, far bigger than any human man, and your body is already struggling to adjust.

Jake abandons his grip on your knee to grasp at your hip instead, fingers digging firmly into the soft flesh. He grits his teeth, canines glinting faintly above you as he curbs the urge to just push past the resistance and slam home.

"Relax, baby, gotta relax if you want me to get it in," he instructs, pushing a little deeper into you. "Fuck, relax…"

You whimper, helpless against the burn as Jake pulls himself back, then tentatively pushes a bit farther, working his length inside. He's just barely past the flare of his pretty blue cockhead, and already you're trembling beneath him.

Endeavoring to obey, you suck in a couple shaky breaths, trying to force your muscles to loosen and let Jake in. Your hand comes up to clutch at the hand Jake has supporting himself beside your head, fingers wrapping around his wrist for support.

Raising his head from your neck, Jake looks down at the feeling of your tight grip around him. A endeared smile curves his lips, his ears flicked forward like you're the sweetest thing he's ever seen.

"Just like that," he coaches, still working himself in slow. There's a strain to his voice, and you know he's holding back for you, watching your tearful expression. "Perfect, just like that."

You keen at the instruction, toes curling. You feel so full, stretched beyond what you thought possible, your hole barely able to contract around Jake's dick. Your back is starting to strain from the arch you're holding, but you can't drop the position, instinctively searching for the right angle to ease Jake's entry.

Jake thrusts again, deeper this time, and a jolting pain shoots through your body. You cry out at the hurt, a sharper sting than the burn of adjustment, and Jake goes stock still, panting above you.

"Easy, easy," he soothes, the hand that's been pressing bruising fingertips into your hip coming up to smooth your hair out of your face. His gaze catches on the tears that are pooling in your eyes, threatening to spill over your lashes. "Breathe slow."

"Jake-" you choke out, your voice strangled by the tightness in your throat, a mirror for the tightness of your cunt. "Jake, I can't, I can't-"

"You can," Jake insists, pulling out just a bit to let you breathe. The pain dulls, but the pressure doesn't cease, leaving you crying and squirming around his dick. "You can take it, baby. You're gonna take it for me."

You shake your head, tears trickling in hot trails down your cheeks, but even as you protest, your hips are rocking in little aborted motions, begging for more without thinking. Jake's own hips adjust in turn, moving in tiny increments, carving out a space for himself inside you.

"That's it," Jake groans, his brows pinching down as the chokehold your cunt has on his shaft starts to loosen. He drops his head down, panting hot against your cheek as he murmurs. "Knew you'd do it. My girl, made to stretch for me, huh?"

You can only let out a garbled moan in response, all the words knocked out of your brain to make room for Jake. It feels like he's pushing up into your stomach, into your lungs, into your throat — like your whole body is filling up with him with each thrust.

Jake starts to move a little faster, sinking in deeper each time. Every time he pulls out, you feel the drag of his new ridges against your inner walls, ribbing up against the gummy flesh in a way that makes your thighs shake. The painful burn is starting to blur into pleasure now, heat building in your tummy even while you wipe tears from your cheeks with clumsy fingers.

Above you, Jake's breathing grows heavy, his ears pinned back flat to his head as he concentrates on getting himself in as deep as he can. It's been a long time since he's gotten to fuck a woman like this; since before he ended up in his wheelchair, and pairing that with all the heightened sensitivities of his Na'vi body is driving him wild.

"Tightest fuckin' thing I ever put my dick in," he grunts, snapping his hips up, tearing a squeal from your mouth. "Holy shit, baby, fits like a glove."

Whimpering, you snake your arms around his lithe waist, holding onto his back as he pistons in and out. Jake growls, his cock kicking inside you, putting a dull, hot ache low in your stomach. Your nails press into his skin, clinging onto the rolling muscles of his back and sure to leave raised marks.

Just like his tongue, Jake's dick is sending you spiraling with embarrassing speed, all dignity forgotten as your mouth falls open in a litany of moans and mewls. Jake finds your lips with his own, drinking in every breathless gasp of pleasure.

"Jake," you whine into his mouth, tasting the salt of your tears shared on each other's lips. "Oh, my God-"

He quiets you with another kiss, licking into your mouth needily. It feels like you're being filled in every hole, stretched open for him in every direction, and all you can do is focus on taking it, your legs and lips splayed open wide.

Using the hand that's not holding himself up, Jake slips his fingers under the arch of your spine, tracing down the bare skin. He palms the small of your back, fingers long enough to reach from the base of your spine and curl over your hip, urging you up so he can rut in at a new angle. You follow the press of his hand, groaning into the messy kisses he's still pressing against your mouth as your arch deepens.

The new angle lets Jake slip in just a bit further, another inch sucked in greedily by your cunt. You both moan together as your walls pulse around him, the ache in your gut twisting into pleasure from the friction. Jake pauses for a moment, your arms slackening around him as he sits back a bit to see how much of his cock has been swallowed up by your body.

"Good girl," he pants, pupils blown wide open at the pretty sight of your hole fluttering around him. He slips a hand between your bodies, thumb tracing over where you're stretched tight by his shaft, swiping up the pool of slick that you've leaked onto him. "Look at that, mama. Sucked me right in."

Not all of it fits — not yet, anyways, though Jake bets he could balls-deep with some practice and a little more stretching. But what you've taken tonight is already more than enough, only a few inches of his base left unsheathed in your plush heat.

You writhe beneath him, breasts heaving as you try to catch your breath. Jake's so deep now it feels like he's pushed out all your air, leaving you gasping and teary-eyed with your mouth lolled open. The part of your brain that's still capable of concentrating on something other than how much dick is currently splitting you open knows you must look stupid, mouth hanging open like a panting dog.

But Jake's eyes meet your face again, he groans, his cock jerking inside you and scraping up against your walls. He looks wrecked, strands of hair sticking to his sweat-damp forehead, his eyes half-lidded.

"You can't look at me like that," he grits between his teeth, driving his hips forward with a snap. The pitiful moan that it illicits from you doesn't do anything to help calm him, and Jake's hand tightens behind your back, fingers dimpling the soft flesh of your hip. "Tryna be nice."

You blubber as Jake thrusts, hard and sure into your core. The weight of his cock inside you has heat burning through your insides, growing a little hotter with every bit of friction he gives you. His respirator thumps against his chest, jarred by his movement.

More tears spring up when he stops again, slowing his thrusts with Herculean effort. He's still trying to take it slow, to give you something easy in return for letting him fuck you how he wants. It's torture, and your hands come up to his biceps, clinging in a desperate grip as you beg.

"Forget about nice, just- just move, Jake, please!" you blubber, and you might as well have given Jake the world.

Maybe if he hadn't been worn down by smelling your sweet slick the moment he'd stepped foot in the lab, or burying his head in your cunt and tasting your need bursting across his tongue, Jake would keep things slow.

As it is, you're beautiful and flushed and crying beneath him, your tight hole rippling around the hypersensitive ridges of his cock, and Jake doesn't have it in himself to draw this out any longer.

"Shit, okay," he breathes, and then he's on you, over you, inside you, and he's finally moving again. He strips his respirator mask from his neck, setting it down beside him and leaning forward to plant both his hands on either side of your head.

Jake draws himself out almost completely, just the tip of his cock left for you to clench around before he rams back in, forcing a breathless moan out of your lungs.

"Jake!" you cry out, hands scrabbling for purchase against his biceps, nails raking against his pretty blue skin. He grunts, letting you claw at him as he shifts his hips and slams home again. "Jake, oh my God, Jake!"

"That's my name, mama," he smirks, his fangs biting into his lower lip. "Don't wear it out."

Now that he's been given the go-ahead, Jake's doesn't hold himself back, devoted to finding a solid rhythm that'll make your legs shake. The weight and heat and girth of him feels like it's being seared into your insides, like the stretch is so tight your flesh is being molded to his.

Every thrust forces a little air from your chest, a little uh-uh-uh that you gasp in time to the push and pull of Jake's cock. You've given up on trying to cling to your apprehension about fucking in the lab, letting every little mewl and sob past your lips. If one of your coworkers found their way in here now, drawn by the pathetic noises you're making, you think you'd be too fucked-out and full to notice.

You let the solid rocking of Jake's hips sweep you up, eyes going half-lidded and tear-blurred as he spears his dick into you again and again. Your legs twitch around his waist, hooked over the muscle tone of his thighs as he drives into your pussy. All you can think about is the coil of heat that's growing tighter and tighter in your belly, the ache that's been growing since he worked you open.

One of Jake's hands slips back down your body, stroking over the sweaty skin of your side. He pauses to grope of at one of your tits for a moment, tweaking your nipple to make you shudder and squeeze around his cock, and the noise you make has his cock jumping inside you.

Grasping lower, he finds your hip again and digs his fingers in hard enough to bruise. He drags you down to meet his thrusts, jerking you on his dick as tears of overstimulation clot your lashes.

The tension in your stomach winds tighter, your body beginning to prickle with familiar heat. It's too much to handle, the way Jake keeps fucking into you, his groans coloring the slick noises your pussy makes as he sinks in over and over.

"Jake, 'm close," you whimper, your hand pawing at his chest, mindless with desperation. You writhe beneath him, cunt starting to quiver and flare around the girth of his cock. "Please, lemme just- please, please-"

Jake's hips stutter at your pleading, his rhythm staggering for a moment before he picks his pace back up, a quick snap of his pelvis against yours. He grits his teeth, the muscles of his torso bunching and flexing as he works to bring you to the edge.

"Yeah, baby, I know," he rasps, pistoning in rough and fast to make you sob, dragging you down to the snap of his hips. "I know, give it to me-"

Your breath snags as Jake moves faster, his hips smacking against the backs of your thighs, sucking in little hiccuping gasps as you feel the coil of pleasure curl taut. You feel yourself tightening around Jake, squeezing like a fist around his girth, and his hips buck wildly, chasing your cloying, pulsing heat.

The edges of your vision start to blur as heat swells inside you, your nerves starting to snap and fray at the edges. Jake snarls, the hand he had at your hip ripping away to find your clit instead, rubbing at the swollen bead, shooting a shock of ecstasy through your body.

"Jake!" you sob, your back arching higher, pressing yourself desperately into his fingers and cock. With one more thrust and a roll of his thumb over your clit, Jake sends you shaking apart, pushing you over the edge.

You cum hard, clamping down around Jake's cock like a vice when the tension finally snaps. Every muscle in your body goes taut as you seize up around him up, mouth falling open in a silent cry.

Your hips jerk up, frozen for a moment with shaking thighs, you see white — and then you collapse, muscles slackening in overwhelmed relief as going lax in Jake's hold.

Jake fucks you through it, hissing as your walls pulse around him, pussy fluttering like it's trying to milk him dry. His tail lashes furiously behind him, whipping through the air as he picks up his pace.

"God, been so long since I got to do this," he growls, ears pinned back flat to his skull. "You got no idea, baby, you're so good, so fuckin' good-"

You can't do anything but whine wordlessly beneath him, your body boneless as you shake through the aftershocks of your orgasm. Through the buzzing in your skull, you can hear him start to ramble, and know he's close. Jake always gets mouthy just before he cums, and he's no different in this avatar body.

"So good," he pants, his brow pinching down as his hips lurch, his head bowing down to hang above your face. "So good for me, cummin' around my cock, I'm gonna-"

Jake manages a few more sloppy thrusts, and then the knot that's tied tight behind his navel unravels. He slams deep a final time before he cums, his lips twisting in a low snarl as he spills deep inside you.

"Fuck," he moans, lurching above you as he spurts hot ropes of cum into your cunt. His fingers flex where they've been pressing bruises into your hip, tightening and loosening unthinkingly.

Even after he shudders through his orgasm, Jake doesn't stop moving, hips slowing to rock into you shallowly, trying to make sure he fucks all his cum deep.

"Jake," you mewl, one hand coming up to pat limply against his chest. He looks down, big eyes blown wide and a little glazed over like you've put him in a daze, but a flicker of energy lights up again at the sight of your tear-streaked face.

His breath is coming quick, hot pants of air fanning across your cheeks, so you grab his respirator from where he'd set in on the padded floor beside you, holding it up to his mouth. Jake sucks in a few impatient breaths before he pushes it away again, crowding over to get a better look at you.

A long, low sigh pushes past his lips as he cranes his neck down, catching your mouth in a kiss. You muster the energy to tilt your head up invitingly, a bloom of warmth blossoming in your gut at the approving sound Jake hums into your mouth.

You take it as long as you can, sucking on Jake's tongue and letting him nip at your lower lip before it gets to be too much. Whining from the overstimulation, you break off from him, pushing weakly at his chest to make him stop the rolling of his hips.

Jake obeys, finally going still, but it's a long moment before he can bring himself to pull out of your warmth. The sudden emptiness makes you whimper, and Jake hushes you sympathetically, running a soothing hand over your belly.

He gets a hold around your waist, pulling you up into his lap with little resistance. Settling onto his thighs, you let your head loll back against his chest, tucked safely into his arms. You feel boneless, your limbs loose and warm and weighed down.

Jake hooks his heavy head over your shoulder, staring down your body to between your legs. His cum is leaking out of you, dripping from your puffy folds down onto his lap. It glows just like his precum did, pretty and sticky and throwing off a bluish light into the darkness of the PT room.

"Look at you," Jake coos, dipping his fingers down to swipe through the mixture of your releases. He scoops some of his leaked seed up, pushing it back into your sore hole while his tail wags proudly behind him. "Put all those pretty little stars inside you, huh?"

You squirm, making a noise of protest as he slips a finger back up your oversensitive hole. Jake smirks, but he draws his hand back, instead wrapping both of his arms around your waist and holding you tight to his chest.

For a second, you just catch your breath, leaning back against Jake's solid weight as he watches a few more droplets of bioluminescent cum slide down your thighs, his tail curling around your ankle. The scientist part of your brain is itching with curiosity about why his sperm literally glows, but you're too blissed out to really care. Besides, Jake filled you up enough that you're sure you'll find some seeped into your panties later.

"That was insane," you sigh, pressing your face into Jake's neck. When he laughs, you can feel it thrum through his vocal cords, and it makes you grin lazily.

"Good insane, right?" he asks, nudging your face with his nose. You snort, because that much should be obvious, given the way you're sprawled out across his striped skin like a melted puddle of pleasure.

"Mhm," you nod, covering your mouth as you yawn. "Can't believe you talked me into this."

Jake purrs, rubbing his cheek against yours. You still can't get over how big his head is compared to yours, the size difference astounding even after you've had your guts rearranged.

"Barely had to convince you," he reminds you, squeezing your sides briefly, and you can't do anything but shrug unrepentantly. Alien sex in your workplace was certainly a gamble, but you feel like it's certainly paid off, even if you're sure you'll be sore in the morning.

You sit with Jake for a while longer, content to sit and bask in his obvious satisfaction. He's purring like a Samson engine, happy vibrations rumbling through his body and into yours while his thumbs stroke up and down your ribs, almost ticklish against your sides.

"My girl," he murmurs, trailing possessive kisses down your cheek and chin and neck, savoring every bit of naked skin pressed against him. "Took me so perfect."

In all honesty, you could sit and soak up Jake's praises for hours, but logic is starting to return to you now that you've come down from your orgasms, and you know you can't stay here all night. Sooner or later, one of your coworkers is going to wander by for an early shift and wonder why all the doors are locked.

"We gotta go, big guy," you say, rolling your eyes at the childish pout Jake gives you. "C'mon, let's get out of here."

"Fine," Jake sighs, looking extremely put-upon to be parted from your naked body. He lets you clamber off of his lap, the tufted tip of his tail giving a final flick before it uncoils from around your ankle. "Wish one of those lab geeks would just walk in here anyways, see you all cockdrunk and full of me."

Wrinkling your nose at him, you sit up and watch as he rises to his feet. "You're a freak. And we'd both get fired."

Jake stretches his arms above him with a groan, relieving his sore muscles from the tension they've been holding. He just cocks an eyebrow at your comment, twisting his back to pop his spine and shoulders.

"You're a freak too," he points out, angling his head purposefully towards the little rivulet of his glowing seed you've leaked onto the mats. His smile is jeering as he leans down towards you, cajoling. "And just imagine the look on their faces when they see you, dripping my cum all over their precious lab-"

"Oh my god, enough," you groan, trying to push down the flustered flutter of your heart. You kick out at him, heel connects with his ankle. Jake almost certainly feels nothing at all, but he gives you a hurt face anyways. He can't keep it up, though, expression morphing into a grin as you scowl at him.

"Okay, okay!" he says, holding his hand up in defeat. "I'll be back in just a minute, 'kay? Just gonna go to the avatar bunks outside."

You nod, tilting your face up to his as Jake bends to press a lingering kiss to your hair. He slopes out of the PT room with easy confidence, looking so natural in his avatar it'd be sort of mind-blowing, if he hadn't just fucked you with it.

The hiss of the airlock sounds as Jake slips into the exit chamber that'll let him out into the lab's portion of the outside compound, and you listen for the sound of his footsteps underneath it, padding away. It's just you in the dark now, settling your chin on your knees as you catch your breath.

You can tell you'll pay tomorrow for what you put your body through, a lingering ache already settling into your muscles, but you can't bring yourself to regret it when sated pleasure is still buzzing through your system. You wipe at your cheeks, rubbing your fingers across the tear tracks that had started to dry in tacky lines down your face, then between your thighs, where your cum has mixed with Jake's, sticky on your skin.

It's not until you hear Jake's link pod start to whir — signaling the transfer of his psionic link back to his human body — that you get up. You gather your clothes from the dark corners Jake threw them too, tossed carelessly over foam rollers and exercise balls. Something deep in your abdomen protests when bend at the waist to pick them up, the dull throb making you groan.

You're pulling your panties up over your knees when Jake reappears in the doorway looking distinctly less big and blue, his wheels stopping just short of the padded floor. The shit-eating smirk he wears now looks just the same it did on his avatar's face, smug as he takes in the luminescent smear of cum that's still visible on your leg.

"That's awesome," he says, eyes roving up your body as you get dressed. You've already got your bra and shirt on, and you just scoff at him as you shimmy into your pants, hiding his favorite view from sight.

Jake must notice the stiffness in your steps as you come towards him, because his mouth tightens sympathetically. As much as he gets his rocks off thinking about how much of himself you stretched around, he's not a monster, and he knows it's got to hurt a little.

"Sore?" he asks, and you nod, pushing your hair back from your forehead, the strands damp with sweat.

"You've got no idea. I feel like I got split in half."

Jake grins, patting his lap. "I gotcha, princess. Come take a ride."

It makes you giggle to see him so whipped, and you can't resist a tease. "Such a gentleman."

Jake's mouth quirks up as you comply, climbing into his chair with a some coaxing. It's a little awkward, and Jake has to keep a steady hand on the tread of his wheels to keep you both balanced, but soon you're sitting on his lap, legs hooked over his knees and your arms wrapped around his neck.

Slowly, Jake maneuvers you both backwards, careful with your additional weight. You tuck your face into his throat with a sigh as he steers out of the lab, hitting the pad next to the entryway door to unlock it.

The halls of Hell's Gate are quiet as Jake rolls down them, his arms pumping on either side of you to keep you moving. You let your eyes slip shut, blocking out the dimmed emergency lights that run in strips low on the walls at night. Everything is sore, but in a good way, sated and tired out and tucked up against Jake.

Jake pauses in front of the door to your room, snaking a hand under your weight to dig in his pocket for the spare keycard you gave him a couple weeks ago. He slides the thin plastic across the sensor by the doorframe, listening for the metallic sound of the lock clicking out of place.

He wheels into your room, coming to a stop by the narrow military-issue bedframe and patting gently at your back. "Hey, c'mon sleepyhead. Time to dress down."

You grumble into his neck, unwilling to part with the comfortable seat you've already got. Jake laughs as you nuzzle into his neck, rubbing your lips against the scruff at the edge of his jaw.

"I get it," he murmurs, giving your hip a little squeeze. "But you're gonna wanna shower, and change, and sleep in a real bed, kid."

You agree reluctantly, though it's not without a murmur of dissent. As you're starting to slip off his lap, though, Jake catches your waist with a hand, holding you still. You blink blearily at him, confused, but he doesn't answer right away, just craning his head down to give you a kiss.

It's softer than all the kisses you exchanged in the lab, no nips of sharp canines or pressure of a big barbed tongue. You melt into it without a question, relishing the feel of Jake's mouth moving against yours.

When you part, his pretty blue eyes are dark. He clears his throat, fingers tightening reflexively around your waist. "Thanks for letting me, y'know…"

With a rush of affection, you understand, and you quiet him with another kiss, a chaste peck on his lips.

"It was good," you whisper, pressing your forehead against his. "Gave me some ideas for next time."

This close, you can see the way the skin around Jake's eyes crinkle in detail, bunching up as he gives you a boyish smile.

"Next time?" he asks, just to make sure. You stroke a hand down the back of his neck, fingertips carding through the mussed, short-cropped hair there.

"Yeah," you promise, returning his smile with a little glow in your chest. He'll stay here tonight, after you've both cleaned up and showered, and you'll get to fall asleep with the warm weight of him pressed next to you. "Next time."
