Nightfury x Lightfury

Story by Twilightfury on SoFurry

This is my first submission/attempt at writing something smutty. I just wanted to get into the action and kind of jump right into things. The story is basically just sex, without any setup, and I didn't really proof-read it either. I'd greatly appreciate any constructive criticism and am definitely willing to flesh out the story more if it gets a positive response. The story was also partially inspired by this picture by Karukuji on FA. https://www.furaffinity.net/view/27652569/

The Lightfury broke the kiss and slowly began to turn away from the male. She snaked her tail under the male's chin as she turned her back to the onyx-scaled dragon and swayed her hips back and forth, pulling him longingly along and giving him a glimpse of her under-tail. The male let out a quiet warble and flicked his tongue into the air, tasting the growing scent of the female's heat on the cool air.

The female shifts her head to meet the male's emerald gaze and she slowly blinks as she flicks her tail away from under his chin. She turns away and luxuriously stretches herself out before letting herself settle onto the ground. She turns onto her side and lifts one of her legs into the air and leans to pass her tongue over her inner thigh. Her gaze meets the hypnotized stare of the male as he lowers himself onto his haunches. He visibly gulps as the female grooms herself and the Lightfury's eyes shift quickly to the small nub of red flesh that begins to poke out of his under-belly.

The Lightfury takes her time as she cleans her scales, carefully removing small burrowing insects and the occasional loose scale. She keeps her gaze focused on her sole observer and notes as his own stare frequently breaks away and glances at her exposed and puffy vulva. He leans forward slightly as the female's ministrations near her crotch and she lets out a low growl, halting him in place just as one of his fore-paws leaves the ground. The male flinches back slightly, the scaled fins along the top of his head flattening. He lowers his head and body to the ground, hiding his growing arousal beneath his dark-scaled form.

The Lightfury resumes her self-ministrations and she takes pleasure in the male's longing stare as her tongue probes the edges of her own sex. She methodically cleans around her slit, licking up her own fluids and arousal. Her heart flutters in response to her own attentions, but she takes pains to betray nothing to the male's careful observations.

The Nightfury's own thoughts depart as the scent of ripe female fills his nostrils. His eyes break away completely from the female's sapphire gaze as she slowly licks along her genital-slit, her tongue catching lightly on the scales surrounding its pink flesh. Her plump, pink mound pulls slightly as her rough tongue passes over it and the Nightfury shifts his hind quarters into the air slightly to take pressure off of his arousal as it pushes itself from his own genital slit.

The Lightfury feels a deep sense of pride in the male's utter attention and apparent devotion to her body. She pulls her tongue away from her slit and leans backwards to expose her belly completely to the sky. She stretches out her hind legs while one of her fore-paws extends downwards and slowly begins to toy with her burning slit. She rolls one of her digits above the small clitoral nub that sits above her sex before she reaches slightly further and stretches and flexes the opening of her breeding canal. She watches the male carefully as a semi-involuntary trill sounds in her throat and she licks the remainder of her own fluids from her lips as his attention is drawn back to her gaze.

The Nightfury watches the female carefully as she gives him a challenging stare. He lifts his head from the ground and, after a warning is not forthcoming, he slowly inches towards the completely exposed female. She slowly massages her genital slit as the male approaches, causing the scent of her heat to cloud his mind further. His attention fixes again on the pink flesh between the light-blue and white scales of the female's thighs. His tongue darts into the air again and again, thirsty for a taste of the female's fertility. He pauses within inches of the female's smooth, scaled crotch and he meets her gaze one last time. The female gives the Nightfury an encouraging warble and the male takes his cue and dives in.

The Lightfury's heart begins to pound as the male opens his maw and his tongue licks up the length of her mound. The rough surface pulls at the sensitive flesh of her genital slit and she feels her spine seizing up as the male begins his assault. Unlike her own careful ministrations, the male takes no care for her comfort as he licks up her puffy mound again and again, drinking up the fluids that drip from her slit. He inhales deeply as he stretches her open with his tongue, forcing it into and along her lightly textured interior.

The Nightfury moves his body over the female's writhing tail. He forces his weight atop the limb and moans as his aroused dragon-flesh is pressed against her surprisingly smooth scales. He places his fore-paws on both of the Lightfury's thighs and he holds them apart while his thick and forked tongue presses deeply inside her. She begins to growl and groan as the male's tongue sinks deep into her and she grabs his head and pushes it more forcefully into her crotch.

The male Nightfury begins to purr deeply into the female and she puts more force on his head, causing his nose to press into her clitoris. The stimulation causes the female to let out a groan with every breath and she tries to close her hind legs as her muscles begin to spasm. The Nightfury fights against her powerful hind legs as they clench around his head, but his fore-paws give out and he finds his head suddenly clamped in the Lightfury's powerful and vice-like embrace. She curls her body upwards in response to a powerful wave of pleasure and her body shudders as the male's thick tongue laps in and out of her passage.

The male struggles to breath as the female's body wraps around his head and fore paws. Her tail strains against his weight and begins to shift back and forth, massaging and stimulating the line of nubs along the bottom of the Nightfury's arousal. The male desperately laps at the female as her walls shudder and constrict around his tongue and, between his inability to get a full breath and the power scent of arousal, the edges of his vision begin to darken and fade. A wave of fluids suddenly well up from within the shivering female and the male closes his eyes tightly and desperately tries to drink up the sweet fluid.

The Lightfury's body shudders again and again as the male suckles on her mound. She gulps down air in a series of quick breaths and her claws dig into and scratch the rough scales along the male's neck and head. He seems to strain against her grip, but she pays it no mind as wave after wave of pleasure pulse through her. She takes in a large breath and feels her abdominal muscles go rigid as a final, powerful contraction rocks her backwards and flat onto her back yet again.

The Lightfury writhes as her pleasure slowly ebbs and she lets out a series of rapid gasps and pants. Her head lolls to the side and she squeezes her eyes shut for a moment before she turns her attention back to the male as the weight of his head settles onto her belly. She meets the Nightfury's emerald gaze as the male pants along with her. He gasps for air for a few moments before he fixes his eyes to her own and his chest begins to vibrate in a deep, contented purr.

The Lightfury reacts quickly as the male's rumblings strain her over-stimulated clitoris. She groans and pushes herself away from beneath the male and his head smacks into the ground as she pulls herself back to her feet. The Nightfury rears backwards in response to the sudden pain that fills his light-headed vision with stars. He tries to stand, but one of his forelegs give out and he falls onto his side. The Lightfury darts forwards as the male groans in pain and she apologetically nuzzles against his head while she supports his weight.

The Nightfury leans into the lithe frame of the female and he shakes his head to help clear it. After his dizziness subsides, the Nightfury pulls away from the female and looks down at her slightly smaller frame and finds the Lightfury's eyes fixed on something lower down. He follows her gaze towards his now partially-flaccid drakehood and it gives a slight twitch as he recalls his own arousal.

The two dragons quietly watch as the Nightfury's pink spear of dragon-flesh grows and the ridged nubs lining its underside flare. The Nightfury becomes aware of the female's breathing as it begins to quicken and he glances towards her as she begins to lean down towards the quivering flesh.

The Nightfury's heart quickens and he begins to smell fresh arousal on the air as the female lifts her hinds off the ground and crouches beneath the male's form. She leans into the musky scent coming from the male's arousal and her tongue darts out to quickly lick over the small bead of clear fluid forming at its tip. The male shivers at the sudden, warm contact and he braces one of his fore-paws on the ground beside the female's light-scaled hide while he places the other on her back.

The Lightfury licks up the fluid beading atop the twitching and now-violet spire before she runs her tongue slowly down the underside of the organ. The male shivers as small waves of pleasure pulse from each of the sensitive ridges and the Lightfury feels her own arousal begin to drip as the male's pheromones do their work. She feels suddenly ravenous for the scent and alternates between long licks along the length and rubbing her head along the nubs.

The Nightfury begins to purr again as the female beneath his ministers to his flesh. He thrusts lightly against her head as she nuzzles into his crotch and groans loudly in response to the tingling and shivering sensation. The Lightfury begins to let out a series of desperate sounding chirping noises and her licking suddenly intensifies. The chemicals from the male's arousal enter her bloodstream and she feels her heat ignite again. Not quite understanding what is going on, the female speeds up her licking, her tongue snaking to the tip of the male's spire in order to soak up every bead of fluid possible. She wines as the aching between her legs grows in intensity and she begins to shiver and shake as beads of her own arousal drip onto the ground.

The Nightfury thrusts lightly against the female beneath him and his eyes begin to dilate as the scent of fertile female enters his nostrils again. He puts more weight on the Lightfury's body and lets out a loud moan as she pulls back before completely enveloping his cock in her maw. She suckles on the flesh, desperately milking it for the musky flavor of its fluids, and the male above her begins to thrust into the warm and rough texture of the female's tongue.

The Lightfury shivers as the scent and flavor of the male fills her maw. Her teeth fully retract in response to some evolutionary prerogative and she curls her tongue along the bottom of the male's rod as he begins to move himself in and out. He places a paw atop her head while he leans forward, his other paw bracing his weight further along her length. The scent of her dripping arousal draws the male forward and he strains to reach the female's slit, pushing himself further into her needy maw in the process.

The female's eyes bulge as the male's length forces itself into the back of her throat and she feels her powerful throat muscles contract and grip the intruder. The male continues to press forward, his neck twisting beneath the female's tail and the desperate Lightfury rolls onto her side, causing the male to slip free from her mouth. She gasps for breath and pulls herself back to her feet before looking around for the male. She glances towards her hindquarters as she feels the male's head dip beneath her tail and she shivers as his warm breath passes over her burning slit.

The Lightfury braces herself for the male's invading tongue, but he only breathes deeply of her dripping arousal. She tries to step backwards into his nose, but the male pulls away and places one of his fore-paws along side the base of her tail. She freezes up in response to the sudden contact and feels a tingling sensation run from his touch and along her spine. She shivers and leans forward as the male's other fore-paw is placed parallel to the other and she turns her head upside-down to gaze back between her legs. Her hind-legs shake and threaten to give out on her as she catches sight of the male's arousal and her heart quickens as the male rears up and crawls along her back, forcing her tail over his shoulder.

The Nightfury feels himself shaking as he presses his weight atop the female. He forces her head to the ground with one of his paws and grinds his hips against her raised hind-quarters. The two dragons shiver as their sexes rub against each other and the male begins a series of desperate thrusts, trying to find the spot to drive his spire home. The Lightfury begins to whine beneath the male in frustration, but the noise is cut short abruptly as the male's tapered tip catches her breeding canal and begins to sink in.

The Lightfury lets out a grunt as the male presses himself beneath her tail. Her lips stretch around his thick dragon-hood and grip every one of the ridged nubs that line the underside of the organ as they pop into her one at a time. The male takes his time as his initial thrust bottoms out into his now-mate. Her walls clench and massage his breeding-rod while the slightly ridged texture stimulates and causes the ridges along his cock to flare. The female moans in response to the ridges lightly scratching and stimulating her and she lets out a disappointed whine when her mate begins to withdraw. Her sudden and rising panic at the departing sensations don't last however and the male quickly bottoms himself out with a powerful thrust before he begins to repeat the motion again and again.

The two dragons moan and groan as they mate. The Nightfury clenches his jaw, his teeth biting into his gums as he thrusts powerfully into the shivering female beneath him. She lets out a series of gasping breaths as her inner walls clench around the male and her tongue lolls out of her mouth. Her tail begins to wag and flail and the male above her grips it against his chest to keep it from getting in his way. He keeps the female's head forced to the ground and lifts one of his hind legs and places it on the female's thigh. He thrusts wildly into his mate and begins to pant as the muscles in his abdomen begin to contract.

The Lightfury squints her eyes as the nubs along the male's cock tug and pull against her stretched entrance and her small clitoris. She feels the male begin to throb inside her and her walls begin to clench and milk the male as her heat reaches its peak. Her breeding tunnel clamps down on the male and pull him deeper inside she shakes and shivers and pleasure erupts from her genital slit and radiates through her body. The male grows and strains at the sudden intense tightness around his dragon-hood and he gives a final, powerful thrust as his ridges swell and flare and his own orgasm shakes through him.

Wave after wave of intense pleasure overpower the male and he feels his cock release it's seed deep inside his mate. The female quivers and shakes as splurt after splurt of seed paint her walls and her uterus before spilling out from the two dragon's connected crotches.

The male collapses atop the female and slowly pulls his sensitive flesh from inside her. Their mixed mating fluids spill out of the female's snatch, but the Nightfury pays them no heed as he nuzzles into his mate's neck and head. The female lets out a contented sigh at her pleasantly full feeling and the two dragons cuddle closely together as the sun sets over the mountains.
