This one's been on the docket for a while and I finally got the chance to get to it - so! The client here wanted some long, detailed TF about Hiccup from the HTTYD series accidentally taking in some of his dear companion's blood... which just so happens to be the trigger for his extended, somewhat painful change into the perfect partner, as a female Nightfury. First it's from his regular human male body, into a female version... and then from there right into a new Nightfury's form.

Toothless, naturally, can tell that something's going on - but when he pops his head in and finds not Hiccup, but instead a full, eager, ready-to-breed female Nightfury there waiting for him, well, what can he do?

I'm told I'm allowed only one more How To Train Your Dragon pun title. >:(This story went up a week and a half early on my Patreon where I've already got some other early-access stuff available too!

And if you're interested in getting something like this done for yourself, I'm always open for commissions <3


The wind blew through the trees overhead, the world cool and peaceful at this time between evening and night when the sun had lowered and the sky had darkened, yet still only a handful of stars showed themselves among the vast field of clouds far overhead. Hiccup tilted his head back and sighed softly where he stood, hands forward and legs spread a little bit. Soft, liquid pattering sprayed out along the grass and leaves in front of him, with them a smooth relief spreading throughout his body - and after a moment he glanced forward and down, licked his lips, gave himself a few shakes, and then turned to return to the camp, busying himself with doing the fastenings of his pants back up. A long day to end a long week, but now he was home free: the sounds of the forest all around, the wind in the trees, the splashing of Toothless fishing around in the little lake just past the bushes.

His muscles ached, he felt a little bit short of breath after everything that had happened recently, and he really wanted nothing more than to just sit down and relax... and now, finally, he could do that. He shook his head to toss his wavy, slightly greasy hair out of his eyes and then plopped down by the side of the fire, a larger bonfire than they might reasonably need between the two of them pushed together and then ignited with a carefully maintained blast of the Nightfury's breath.

They deserved the indulgence, though. Hiccup spread his legs out before him and rested his weight back on his hands, head hanging back to look up at the night sky far above. The human swallowed, took in a slow, steady breath, and closed his eyes, letting himself sink back until he lay fully on the ground with the dirt and forest litter spreading out around him. Toothless's nearby splashing had since stopped, which meant the dragon had likely caught his quarry and was now coming over to present it to his rider, which meant that if Hiccup were to wait another few seconds and then open his eyes again...

...he would look right up into that familiar salamandrine face, huge green eyes innocently rounded with expectation, fresh wetness glistening off of his leather-black scales. Hiccup waited for that empty mouth to open and drop the fish directly upon his face, but just as he saw Toothless move to make the expected motion, something else caught his eye and the human sat upright, quickly turning around and taking his companion's head in his hands.

"Hey, hey, hey. What's going on here?"

Toothless's eyes widened as the human handled his jaw, thumbs unabashedly slipping up between his lip and over the ridged, expectedly toothless gums. The teeth were there, of course, hidden beneath the flesh and within the jaw itself, but that wasn't what bothered Hiccup now. What he sought was the source of the trickle of blood oozing out from the dragon's mouth, limp grey fish flopping in a pool of saliva mixed with lakewater along his bottom jaw. The dragon sat up a bit, forelegs straight against the ground, and let his mouth fall open so that Hiccup could push his entire head inside.

"Oh, come on." He poked around at the flesh there, peered at the substance on his fingers, and grimaced. "Again? You need to be more careful. We've talked about this."

Toothless let out a low grumble and leveled a steady gaze at his rider, then, as Hiccup retreated from his gaping maw. He took the fish with him and gave it a wiggle in the air, shimmering scales and pale flesh bouncing away from the jagged bone protruding out the side. The dragon looked from his rider, to the fish, back to Hiccup, and then flicked his tongue out over the blood oozing from where he had cut himself in catching the thing.

"Look - see?" Hiccup took a step back, held the still dripping fish by both ends, and leaned in to take a bite from one specific spot around it. In the past he would have, and definitely had, hesitated to eat anything from right out of a dragon's mouth, but at this point he and Toothless had become basically inseparable. Anywhere one of them went, the other had to follow: they worked as a unit, as a single mind, and neither would have it any other way. "From around the bone. Not through it. It's hard, I know - the small ones you can crunch right through, but still be careful - but, come on. Ah, this needs some salt... come on, let's run home. I'll have Astrid mix up a salve for you." He took another bite of the fish, then reached down to swipe his bag up from where he had left it beside the fire. "Again._We can make it back here after since I don't want to leave this fire burning on its own, especially after _last time, but we gotta get you patched up."

He leaned in to take one last bite before climbing up onto the dragon's back, Toothless rolling his eyes and lowering himself down for his rider - but as he settled into place Toothless frowned, reached up, and touched at the corner of his mouth. Something hot sizzled at the edge of his lip there, brighter and richer than the raw viscera of the fresh fish itself... he frowned, looped the reins over one of his hands, and peered down at the limp half-eaten form. Was that some of his own blood trailing down the revealed spar of bone, or was that still his dragon's...?

Surely it didn't matter. He wiped at his mouth again, shrugged, and then took another bite. Raw fish certainly wasn't his favorite meal, but sharing things like this brought him and his dragon closer together, and he knew that it signified something to Toothless deeper than his human sensibilities and culture could understand. And that in itself was worth it to him.

The world around them pulsed and swayed as Toothless took flight, great wings pumping at the air and lifting them up. Like bouncing atop a vast bowl of gelatin that someone always brought to the village bonfire every year, it took a few cycles from the Nightfury's wings to really get them into the air - and then Toothless sped the two of them off and away, clean and precise as a perfect arrow.

The stairs seemed to spin underneath his feet as Hiccup tried to make his way down, stirred awake in the middle of the night by an encroaching need inside of him. He clutched his belly with one hand and hung onto the railing with the other as he went, eyes halfway closed beneath sleepiness as well as the strange feeling that washed over him, radiating up and out from the pit of his stomach and shivering out along his limbs.

Maybe he had gone too far on that raw fish that Toothless had given him. Maybe it was the ale that had been waiting for him here when they had come home, a little bit warm but definitely still drinkable... maybe it was a combination of both of these and more. As he wobbled his way unsteadily down the stairs, for a moment he wondered if the island had finally shaken itself free from whatever held it down and now floated free atop the swirling waves of the ocean.

And how suddenly it had hit him had put a shock through his system as well. At first he was pleasantly snoozing off the night, not a care in the world - and then suddenly he felt the cold, solid thump of the floor against his chest and cheek when he fell out of the bed, combined with this deep, resounding ache that tingled right down in the pit of his stomach and root of his spine. Coughing and groaning, he had managed to crawl over to the table by the window, pulled himself up, and caught his breath there, only to look through and see Toothless down there outside where he always slept, eyes wide, concern evident.

Stay there, Hiccup told him with a wave of the hand. Don't worry. I'm okay. Just stay there. So then he'd closed the window - really, he was fine: this was just the result of something from earlier in the night - straightened up, tried to swagger his way over to the stairs... then stumbled there, nearly fell down, and had to lurch to the side and heaved across the railing into an unsightly splatter down at the foot of the landing below, the taste and sensation foul in his mouth.

It wasn't just the slight nausea that roiled inside of him on his way down the stairs, but the odd tingling at the extremities of his limbs as well. The human paused to bend over the railing, coughed a few times, reached up to wipe at his mouth - and instead of smooth skin pulling across sticky bile and saliva there, felt the distinct drag, tug, and scrape of something more similar to dragon's scales. He looked down, blinked through the fog of sleep and sickness, and saw...

What did he see? The world swam around him again, and next thing Hiccup knew, he had splayed out across the railing of the stairs, drool dribbling from his open mouth while his chest heaved in slow, steady gasps, trying to draw in breaths that seemed like they just wouldn't come. That tingling in his hands had grown into a burning, the muscles of his fingers twitching and tightening and pulsing, but - the sensation spreading out through the rest of his body grew and strengthened as well, spreading out from this spot down in his belly to shoot its tendrils up through his chest and down his legs, wrapping around his throat, his thighs, his loins.

Hiccup called for help, trying to alert Astrid and whoever else might be around to hear, but his voice felt weak in his own throat. Naked as he was, it felt almost as though there were a hundred fingers, searing hot, trailing up and down across his body, squeezing in on his muscles and piercing through flesh, pulling and tugging and shaping, and... and the pressure against his chest started to grow, first sending him into a panic that he might not be able to breathe within a few seconds more, until he straightened up, arms shaking where he braced himself on the railing.

He looked down and saw there, the skin and flesh of his chest actually growing and expanding out, the lines of muscle atop his sternum stretching out, growing taut, then spreading in mass and volume. Thick tendrils curled in from underneath his arms, wrapping in and around - and lancing through his nerves wherever they went, resulting in a constant, sparkling stream of sharp pain echoing up through his chest and along his ribcage. Hiccup tossed his head back and groaned with the sensation, legs shaking as well as the same sort of change began in his lower body as well, hips shifting and churning, the bones of his pelvis seeming almost to grind and scrape against themselves as something about him continued to change, to evolve into something new.

The human groaned, then did so again, and finally reached up with that half-misshapen hand to clutch at his throat as something there_tightened and tweaked as well. He swallowed, swallowed a second time, grunted and bent over the railing again - these were _breasts pushing their way up and out of his chest, nipples shifting just slightly to settle in along the proper spots, the thicker curls of hair along his chest and belly pulling back into his skin to settle at a thinner, softer haze - and coughed a few times, each one a little bit higher, a little bit warmer than the last. His bones felt like they were forcibly reshaping themselves, shoulders tugging up and back, chest pushing up, spine arching... pelvis becoming heavier, yet at the same time angling in a different way, and... then the pressure slid in behind his loins as well.

That really made him panic. He squeezed at the railing of the stairs, standing halfway between two of the steps, and let a wave of discomfort and deep, resounding pain rock through his body, then did so again and again. Before his eyes clouded with tears and fog he saw himself - himself, halfway hard still from waking up in the middle of the night, twitch and pulse and... start to retract, pulling up into his body, wiry hair at the base straightening out and shortening just a bit. With that sensation, though, with the reverse-vacuum feeling that pulled in along his front came a little bit of pleasure, hidden deep inside far away from where he usually felt it. Internal valves and tubes tugging and pulling and shifting, tightening and relaxing; buried muscles forced to tense up, electric shocks zapping back and forth through him, there was nothing he could do to resist the unsteady thrusts, forward and back, that his lower body reflexively made against the sensation.

His tongue flicked out over his lips and he gasped and grunted again, then tried to call for help one more time - but it wasn't his own voice that came out of his mouth, then, but rather that of some woman he didn't recognize. The walls of the house were basically soundproof and he slept on his own upstairs, which meant that anyone who could have heard him, wouldn't be able to anyway.

Still his hips thrust and bucked, one scaly hand coming to his throat, feeling at the altered muscles there, and then pushing down his body. His legs shook beneath him both from the dizzying sensation of the change as well as from the overwhelming mix of visceral feelings rushing through him, pain and discomfort and that same deeper, richer pleasure. Every time his muscles tightened and he bucked forward, a cold shiver arced down his spine and he gritted his teeth together so tightly he thought he could feel them crack, even as he felt their short, blunted shapes crackle into longer, sharper weapons right there in his jaw.

All of these flooding hormones and zapping nerves meant that he was by now fully hard, though when he looked down again between eyes brimming with tears he could barely tell. Each thrust up towards the railing of the stairs sent his still-shrinking shaft and sack swinging forward, both barely visible within the now reduced puff of pubic hair there as well. Warm skin tinted to a fresher, richer pink, then glistening red further down; the loose, wrinkled skin of his sack pulled up and in towards his body. He gripped at one of his breasts and the pert nipple protruding from the skin there, the quick contact sending another electric shiver through his body, then ran that hand down along his bare chest and belly.

Sleek, tight muscles wrapped in around him, his body suddenly much smoother than it was before, hair having turned to a thinner, softer coating of sorts around him. As he dropped lower, legs shaking and threatening to give out from under him, Hiccup hooked his thumb around the base of his twitching hard shaft, fingers curling in underneath in the center of what used to be his sack - and that touch was enough to send him over his unexpected edge, another intense, body-shaking pulse bouncing back and forth through him when he emptied out a few ropes of thick, milky white out between the pillars of the railing. Again and again the sensation shot through him, this time fully bringing him to his knees; he grunted and groaned, this unfamiliar woman's voice ringing in his ears right out of his own throat, and bucked again, dribbling the last of his load out onto the ground between his knees.

This time when he moved and shifted, he could no longer feel the swing and pull of his own equipment, so to say, hanging down between his legs. The front of his body thumped down against the wooden floor, new breasts pressing painfully up into his chest and hair spreading out around his shoulders, much longer than it had been before; he swallowed, panted, let out another noise in a voice that wasn't his own, and ran his hand down his body, this time feeling his smooth belly stretch out into a slight bump and mound of his pelvis beneath smooth skin and flesh, and then beneath that the distinct, sensitive_pair of slick, wet lips. The flesh was still molding and taking shape, and he could feel his skin move around beneath his fingers almost like liquid - until it really _was liquid that stuck to and dribbled from his touch, little echoes of fervent pleasure bouncing and reverberating out through the sharp waves of pain that still shot through him, nerves constantly firing, disconnecting, reconnecting, firing.

He had heard as well as seen many almost inexplicable things these past few years, but this... finally the sensations seemed to come to a stop, almost every inch of his body numbed beyond feeling from the forced changes. Hiccup sighed and panted, drool and bile still dripping from his lips, random muscles across his body reflexively tightening and twitching in the remaining throes of the transformation, while he tried to gather his senses. Maybe it really was the warm ale; he thought he had detected a hint of something else in the flavor, something a little sharper and acrid like vinegar, or -

In the middle of his thought he paused again, bleary eyes refocusing on where he had his hands braced against the wooden floor. Sweat, saliva, and liquid arousal dripped from his body, hanging down off of his long, silken hair in thick drops and strands, but there along his hands his skin had continued to morph and change, rising up in the sleek sharklike scales that some of the dragons around here exhibited. Smooth and sleek in one direction, rough like rubbery sandpaper in the other... a familiar feeling to him, one that had given him more than his fair share of scrapes and bruises.

The skin of a Nightfury. Hiccup swallowed again, tried to sit up with his ankles underneath him, and reached in with that same hand to touch and feel at his teeth and gums. First it was his own taste that washed over him, rich and sharp and so different from what it used to be, at its root the same yet still tinged, tinted, skewed. The arousal that pulsed through him also felt the same and yet different: still his muscles clenched and twitched, yet there wasn't quite as palpable a throb through his loins. He reached down and touched at himself again and again, fingers slipping up and over soft lips, in between slick, wet walls of flesh and muscle, up towards the spot where his shaft had completely re-formed into his body with that little, hypersensitive nub of flesh there... and found that as he closed his eyes and lost himself in the feeling and sensation that, for once, something new and different filled his mind, especially as he felt at the sharp yet rounded teeth in his mouth and the respective slots within his gums and jaw, where they would retract when not in use.

It wasn't Astrid in his mind, sleek and strong and obviously human as always before, but rather... smooth black scales like the ones that grew along the backs of his hands and spread up his arms, tight and muscular, smooth and aerodynamic, like halfway between a salamander, a skink, and one of the great old wyverns from before.

His reprieve was short-lived, however, as yet another pang arced through his body, this one resounding deeper than anything else he had felt so far. The floor rushed up to meet him again, and for a second Hiccup stayed there on his face, bare feminine rump hiked up into the air, while stars and black spots swam behind his eyes. The taste of blood oozed into his mouth, and with a slow, careful flick of his tongue, the characteristic Nightfury bifurcation cutting in towards the center at the end, he could feel that his sharp teeth had started to sink back into place in his jaw.

One pull at a time Hiccup started to drag himself up towards the door near the end of the stairs, though his process was slowed by the constant pain and pressure, feeling as though there was something _much_bigger than his own body trapped inside of him, trying to force its way out through the spaces between bones and tendons, shredding him from the inside out.

As smoothly and simply as these breasts of his had grown, now he could them slipping away from him, fat and flesh and muscle melting into a mess inside of him and reforming into his body. What was there before slid away and pulled back, skin tightening, stretching, nearly breaking like a sheet of thin rubber left to dry under the sun: he gritted his teeth and tossed his head back, a not-quite-human growl rumbling from deep within his chest as his flesh continued to change, the sensations and pain far beyond his limits.

Still, though, as he crawled his way to the door, as this sensation of boiling liquid pouring both over and through his body kept him ignited with sharp, sparkling agony, only one thought persevered in his head - and that was still Toothless. Once Hiccup made it to the door he sat up and leaned against it, then gritted his teeth - or his bare gums, rather, as by now those teeth had completely retracted into the bone of his jaws - and found himself convulsing all over again, trying to worm his way away from the hard surface so his muscles beneath shifting liquid skin could have a break. He felt those muscles lengthening and tightening, weaving and reworking themselves like thick elastic cords beneath his skin, curling around underneath his shoulders towards his back, coming up and looping around his neck... he arched forward, slammed his forehead against the door, winced in pain, and tasted another splash of blood oozing out across his tongue, now thick, broad, and sporting the same fork at the tip that he had seen in Toothless's mouth.

He fell back onto one hands, joints of his fingers seeming to lock up and force into the position of a dragon's forelimb, then reached up with the other for the door's handle. His eyes blurred before him, optic nerves forcibly adjusting and reconnecting to the new biological mapping from the body that encroached upon his own.

My own? Finally he managed to grasp at the handle with misshapen, twisted fingers, his own weight pulling the door open until it swung out and spilled him onto the cold earth outside. Once more he arched in an all-over convulsion, shoulder blades pushing their way out and to the side along his back to make way for the new spars of bone that sprouted up from the back of his ribcage, digging out from inside of him like deadly sharp fingers. He threw his head back, choked back another yelp of pain that no longer sounded like the female voice he had had for a few minutes, and came forward again, only to this time knock his chin on the stepping stones leading up to the front door of his house.

His jaw, too, had started to morph and pull away from his head, fresh newly-grown bone filling in the spaces between what was already there as it broke itself again and again, stretching out sideways to occupy the rounded, spade-shaped head of the dragon he was becoming. Each time he tried to call for help, the sound came out less as a word and more of a guttural growl, the kind of chirping bark that he had heard so often from Toothless.

Which, thinking of that broad, powerful Nightfury... Hiccup twisted and gyrated where he lay across the ground, trying at first to stay on one side of his body and then the other as his muscles continued to shift and transform. His arms, now coated halfway to the shoulder in that thick, sleek, deceptively rough scale-like material, shook underneath him, pulsed like sausage casings about to burst from too much pumped in. His shoulders pulled up and back, snapping and then socketing back into place with the surrounding bones fusing and shaping - and through the pain all he could think of, all he could want, was that other damned dragon.

That other dragon. Already he was thinking of himself as one as well, his wings growing up over his back and spreading out like hands stretching their fingers out, the back of his mind tingling with the unfamiliar sensation of new kinesthetics. After each body-wracking shock of pain, sharp and bright and so intense that he thought he blacked out as they pushed through him, he swallowed again, tasted blood and bile and something deeper and richer, more feral, more twisted - and felt the same arousal from before still echoing through him, pulsing, twitching, slowly starting to throb again.

Once more he rolled over onto his side, one of his half-grown wings caught beneath his shoulder, and gave a fervid thrust from his hips, suddenly much further away yet at the same time easier to reach than when he had been a human. The scales had started to spread in along his throat and then his chest as well, now smooth, sleek, flat, and ridged in the pattern characteristic of a Nightfury's underside. As he squinted through halfway-formed eyes Hiccup curled in along himself, his now broad thighs stretching apart for his long head and neck to come in close to himself, and he watched the slick, wet lips of his still mostly human sex pull together, retract right back into his body in a warm slit, and then start to shift down towards the wrinkled pucker there at the base of his thick tail.

Another shiver launched through him, and his ears - while their change had still put tears in his eyes and made him grind his freshly-reshaped jaw, it still hurt marginally less than full-on bones cracking and filling back in - flicked and adjusted back towards an approaching sound. Hiccup swallowed, squirmed his unfamiliar limbs around his body, everything thicker, denser, more muscular, yet at the same time more streamlined for flight. He tried to call out for whoever might be nearby, though his altered throat, fully draconic, just gave another of those same needy barks as before.

His scent had changed again. Curled up like this, body convulsing and back trying to arch forward under the strain on his spine of pushing a dragon's tail out from the base of his body, his rounded nose brushed up against the interior of his thigh and each gasping inhaled breath returned that new spice to his heightened senses. Sharp, rich, bright, vaguely familiar for his own original human musk as well as Toothless's, but then distinctly altered in its own way; he swallowed again, let his forked tongue hang out from his mouth, winced as some bodily reflex still out of his control forced his buried teeth to shoot out of his ridged gums, and felt his body tense all over again, the forced muscle movement causing a slick, sticky dribble of liquid arousal to ooze out from his slit.

There was that sound again, heavy plodding footsteps coming from around the back of the house, cutting through his own fervent panting, the creaking and cracking of muscles, and then scrabbling of his own claws - claws, thick and broad, tighter than the fingernails that had been there before - across dusty stone. Now Hiccup, completely unrecognizable from the human he was before, tightened all of his muscles again, ran his nose up along his fully reformed sex, and dug in until his nose slid between the sensitive lips, like warm wet silk parting around him. He took in a breath, felt it fill his lungs now expanded and adjusted to provide extra efficiency at extreme high altitudes, and tasted nothing but himself, now pure female Nightfury even as the last vestiges of his human body trickled away beneath the reformed muscles, streamlined body plan, and altered-density skeletal structure.

He could feel his heart pounding deep within his barrel chest at a different pace, in a different rhythm, with a different strength. Still the residual aches and pains bounced back and forth through his system, reminding him again and yet again of every new nerve and inch of body space he had: the thicker fingers and toes, the different proportions to his four limbs, the extra wings along his back that now tucked close to his body... the swaying, sweeping tail, whole and intact with the spreading sail at the end, and then finally his neck, his head, his protruding ears, his teeth and jaws. The Nightfury gave himself - _her_self - another shake, shivered all over, struggled to pull herself to her feet, and waited for the last echoes of the unexpected transformation to fizzle out of her system.

Thoughts and impressions of thoughts wove their way through her head, so similar to things she could remember yet just out of reach. She swallowed, tasted that blood and stench in her mouth again, gulped it down, and looked back to the house behind her, door standing open and swinging slowly outward with a gentle breeze blowing through the town. Some kind of recognition twinged in the back of her head, but at this point it was far from something she could reach out and grab on to. She slitted her eyes, then let them dilate again to sweep in as much of the dim midnight light as she could; she lifted her rounded head to the cool air, took a few sniffs, parted her lips to let her forked tongue hang out and aid in the exploration, then froze.

There was something there, just around that corner. Something interesting, something invigorating, drawing her forward, fueling the arousal that already stirred in her loins and sent a sweet, eager tingling through her lower body. That was part of what kept her broad tail hiked at the base, tailhole and slit on full display and twitching, the latter engorged, dripping with slickness, blue-black flesh tinted warm pink from the sheer heat radiating from it.

The Nightfury lowered herself down to the ground to keep a smaller profile, flexing each of her stout limbs in turn as she moved forward. Ground locomotion was not her breed's favored mode of movement, but she was still a Nightfury nonetheless, with stealth and silence unrivaled to all types of dragons other than another Nightfury.

To her surprise, shock, and then deep pleasure and enjoyment, this was the first thing she saw as she crept around that corner - or, rather, the first thing she saw was his tapered length, warm pink flesh glistening with the natural liquid musk of his arousal, twitching and throbbing beneath his smooth underside. He stood upright and straightened up a little bit further when his wide green eyes fell upon her. He tilted his head, twitched his nostrils in drawing in her scent just as she did his, then swished his tail, at the end of which flashed a colored, artificial replacement in place of where one side of his tail-fin should have been.

The male Nightfury then tilted his head the other way, waiting for her to make a move before him. She crouched down and kept herself close to the ground, still creeping slowly forward in case this was a show of territorial dominance from him instead of what she wished and desired it to be. As she drew closer her nostrils flared and drew her in closer, his scent wafting up and around her head, slipping into her throat and filling her lungs, and it was... familiar.

Here in front of her the male lifted one of his forelegs and halfway leaned to the side, drawing his hard, twitching shaft further up into the cool night air, where glittering moonlight played across its velvet-slick surface. It tapered from the tip and grew in girth down towards where the lips of the dragon's slit parted around the base, folds of warm flesh visible just out of reach inside; he shifted again, flicked his forked tongue out across his lips, and then flopped down fully onto his side, one wing stretching up over his body while he lifted both of his legs on that side.

Then, in the cool night, he gave another twitch and throb, and a small spurt of clear, intoxicating pre jetted out and across the scales of his belly. The hydrophobic nature of Nightfury skin meant that this squirt remained in little glittering jewels, quickly rolling down off his underside to drop into the earth underneath him. The female Nightfury - something else twinged in her head, something like a half-remembered dream just beyond what she could reach - tilted her head as well, met his eyes, lifted up a little bit... then jerked back when he leaned down to lick at her snout.

Toothless. It came to her more as a feeling than a conscious thought: this was Toothless here before her, and she was... Hiccup? That seemed almost right, but she couldn't tell. The two dragons held each other's gazes for a moment, one head tilted one way and the other the other; then his mouth came open and his tongue lolled out, and with the slightest of motions he guided her down his sleek body.

And she eagerly obeyed, though it was as much her own interest as it was his. The closer she came, the stronger his scent built in her nose and drew her in even closer, until she wanted nothing more than to... she swallowed and opened her eyes, just in time to see his arousal twitch just above her snout again. It was clear that Toothless could feel her breath puffing out across his sensitive skin, as each time she drew in a taste of his scent and then let it back out, he twitched yet again and dribbled another little spray of pre across his own belly as well as her head, her face, her cheeks... and then finally her tongue when she nosed up, parted her lips around his tapered tip, and started to dive slowly down.

Above her the male dragon made a low, rumbling sound of pleasure, his wide hips giving a gradual push upwards against her descending maw. He fit quite nicely inside her mouth, scent crystallizing into taste, sharp and musky and rich and delicious, so familiar to her that it just felt natural. By now she had full control over her teeth and kept them intentionally retracted, running her broad tongue back and forth along his underside with the fork in the end providing a subtle cup around as she went. Drool and natural slickness mixed with his little spurts of pre in the back of her throat, until every single breath tasted strongly of him and nothing else.

The very same kind of interest burned inside of him as well, though. While the female Nightfury busied herself here down between his legs, drawing her tongue back and forth, diving up and down along his shaft, then at one point even retreating just so she could dig her nose into the base where his length protruded out from his slit. That in particular made him throb and grind forward against her, smearing his scent even deeper against her face until when she breathed through her nose, even after lifting away from him, all she could smell was him.

This male Nightfury, this Toothless, wanted to claim her as his own... and, of course, he had also picked up on just how much _she_wanted it as well. A warm tickle down near her own loins startled her, and she glanced down from behind his hard shaft just in time to see his wide body curling around her from above, the male's snout trailing down along her lower belly. First he sniffed at her slit, swollen and pulsing gently with peaking arousal, then shifted up to do the same to her puckered tailhole as well; then he angled himself down again, pushed his hips a little bit more firmly against her face, met her eyes once more - and then, still watching her, let that broad, forked tongue flop out of his mouth so he could drag it slowly, firmly up over her slit.

Then he did so again, and again, and again, each time turning a new direction and approaching her differently, slipping his tongue in between the folds of sensitive, supple flesh, sliding a little bit deeper. The female Nightfury's legs gave a reflexive kick in response to the sensation. The two dragons lay there for some time more, halfway wrapped around each other with long necks and wide heads working in rhythm, digging and licking and sucking at each other, getting to know the new, familiar, yet still strange scents of their partners. The female Nightfury shuddered and kicked around Toothless's head buried against her genital slit, and for a while she let him focus on her while she just breathed along his shaft, the male's hips now rhythmically pushing and thrusting against her.

Soon after, as expected and as hoped, Toothless moved to untwine himself from around her and stood back up on all fours. His long tail swung eagerly behind him; he spent a few moments flicking his forked tongue back and forth across his lips and gums, dripping with the thick slickness of the other dragon's arousal, while he waited for her to move as well.

She looked up at him, felt the weight and sharpness of his gaze further fueling the flame burning in her chest and loins, then got up as well - and promptly turned her back to him, in one smooth move lifting her tail, curling it forward, and spreading her hind legs. The female Nightfury felt her tailhole stretch slightly with the movement, wrinkled pucker pulling and straightening up with her lifted tail, just as her slit did the same: she swallowed again, tasted him in her throat, and swung her head to look over her shoulder at him.

He blinked, licked his lips again, and swallowed. The female Nightfury swayed her hips side to side, lowering the front of her body down for extra effect, and felt a thick string of dripping warmth sway against her inner thighs with the movement; Toothless took a step and a half forward, sniffed at her again, gave one last deep lick from the tip of her slit all the way along the rim of her tailhole, which made her gasp and release a little puff of purple fire from her parted mouth. Then he hopped up on top of her, settled his forelegs first along her shoulders and then on either side of her body, settled down into place... and started to sink forward and down into her.

Immediately both of the dragons shuddered and rumbled with the sensation, immense heat sizzling between the two of them as Toothless pressed deeper and deeper. The female Nightfury's mouth came open again and she pushed up against him, loving the way that his tapered length spread her slit and plunged into her depths, simmering with natural heat as well as expectation and desire. With his belly against her back, each one of his tense, measured movements rippled down through her body, his sleek and toned muscles tensing and shivering in turn as he thrust himself deeper, down to the base, then started to pull back again.

So again and again he went at her, gradually widening his stance until he could comfortably piston his powerful hips against her, shaft buried deep inside of the other dragon. Even from here she could hear the rhythmic, wet schlk-schlk-schlk of him digging deep and pulling back out, all of her internal muscles reflexively pushing back against his tapered length when he pressed in, then squeezing tight as he tugged out in attempts to keep him buried there.

The sheer need for him to breed her, to fill her up, thrummed through her in greater strength with each thrust deep. At the base of his shaft still halfway hidden within his slit the male Nightfury had a sleek, slim knot, a tight bundle of muscle that, once he hit his peak, would tie his body to hers for the remainder of his finish to ensure that all of his seed would spurt deep inside and take root there. His head pressed down along the side of her neck, and she tilted hers to the side to make room for him and his raucous, panting breath, each exhalation smelling just the same as when she had first curled in around and gotten a good sniff at herself and her new equipment.

As he railed quick and hard at her, Toothless wrapped his tail around hers as well, smooth organic flesh brushing up against the cloth-like material of his prosthetic fin there. Its presence added an extra burst of electricity to the mix, tickling at something else familiar buried deep beneath her primal instincts and feral needs. It was there, and she _knew_it was there, but she couldn't quite grasp at it - and besides, right now there were other, more immediate things claiming her attention.

Claiming her attention, her mind, her body... claiming her. She lifted her head and pressed it against Toothless's, wanting to feel his breaths against her scales as he pounded her deep. Beneath that panting she picked up little bits and fragments of rumbled pleasure as well, shivering low each time he hilted himself inside of her, to the point where she could feel the bulge of that draconic knot kissing up against her already spread slit, slipping up through the lips there, then sinking in among tight walls of sleek, slick flesh, her own internal ring of muscle squeezing back around it to keep it buried there. Still, though, Toothless tugged it back and then pressed it back in, again and again and again, until - his breath caught in his throat and he threw his head back, his own ring of purple flame issuing forth and up into the sky... and only then did the female Nightfury feel him bury deep inside of her and stay there, his entire lower body pulsing with the force of his finish.

She could feel it spurting out into her as well, thick ropes emptying deep, forced into place with nowhere to go but further in what with his sizeable shaft and the tie between the two of them. She let out her own rumble of moaned pleasure and clenched back against him, rocking her hips in a way that she instinctively knew would draw more of his load out. Her wings wanted to flap and pulse, the female's body filled with this restless yet delicious energy, herself shivering underneath the male as he continued to press himself forward and down, retractable teeth revealed and gritted together, and the entire lower half of his body twitching as well with the feeling.

Finally, after what felt like minutes of thrusting and throbbing and that slow, thick trickle deep inside of her, the male Nightfury rested back and let his head drop along her shoulder, hot breath puffing out from flared nostrils. Still he remained buried inside of her, as he would for some time more: the tie ensured that. He nuzzled down along her neck, and she lifted her head to return the touch. Something inside of her recognized him just as much as he did her, though still she couldn't quite identify what.

It just felt right. Each of the Nightfuries rumbled and settled down into place there, still cradled in the cool arms of night.

Astrid poked her head around the corner, spear at the ready, then just as quickly hid herself once more. That certainly couldn't be right. There had been some strange noises come over from Hiccup's house, and when she had managed to rouse herself awake and come to check things out, his window was closed and Toothless was gone.

At least until she had turned the corner to the front. Still the noises rang in her head, heavy and wet and sloppy and messy; she licked her lips, took in a breath, and then leaned over again, this time affording her quite a full view of the familiar male dragon, complete with his repaired tailfin, straddling what looked for all the world like another, female Nightfury shivering underneath him. That was the part that baffled her. Where and when had another come from, and how had she managed to find her way here to him of all places, catching his attention so that he would...

Realizing that she was staring, Astrid swallowed and averted her eyes from the source of that wet sucking and slurping. Even from here she could feel their rumbles of pleasure vibrating through the air, Toothless's green eyes halfway lidded against the feeling. She knew she would have to go find Hiccup and let him know, and - and the female tossed her head, let out a little sound, and turned her head to stare straight back at Astrid where she hid, as though the dragon had known her presence the whole time.

Something in that gaze held her for a moment, her head and blonde hair hanging right out in the open while she watched, and while the dragon watched her. This was still without a doubt a Nightfury, but... something in the eyes, and the shape of the mouth, and the way she watched Astrid... when she slipped back behind the wall to gather her thoughts she heard the dragon let out another sound, this one seeming a bit lower and more... disappointed, almost.

What a strange situation. Astrid swallowed and shook her head, then started off towards the center of town. It was too early to raise an alarm to find Hiccup, so she would continue looking for him on her own - and once Toothless had finished his business over there, she was certain he would be willing to help as well. It would be far easier for him to find his dear rider.

The other Nightfury's face stayed in her mind as she started her search, though, tickling at something back in her memory. Just what, though, she couldn't tell. It would come to her eventually.

She just had to find him first.
