After mating with Toothless, Hiccup and Astrid find themselves transformed into a Night/Light Fury. This gives them a unique opportunity to discover the extent of draconic pleasure.


The next morning came like any other. Fishleg's helmet, which he'd used to cover his eyes, was no match for the beaming rays of the morning sun, which woke him to greet Meatlug in the stables.

Snotlout's heated dream of pleasuring Astrid was also cut short by the relentless beams of light. The twins were already awake, as they didn't want to be late for the morning show they broadcast all over the Edge.

Hiccup and Astrid were still chaotically intertwined with Toothless when the sun hit their naked forms, the light glistening in Hiccup's dark scales...

When Hiccup tried to open his eyes to see his most beloved friends, his eyelids felt strangely heavy. As he took a deep breath of the morning air, he was surprised to find that his lungs felt only half full, even though he inhaled as usual. Something didn't feel right, but it was hard to tell if he was still dreaming or if he was suffering from the worst hangover ever, even though he hadn't drunk anything.

Hiccup tried his best to keep his eyes open and look down at himself. The movement of his head felt very strange, but he was relieved to see Toothless' belly right below him.

Wait a minute! Toothless is here, so this must be another Night Fury!

The only reasonable explanation for seeing the bodies of two Night Furies was that there were two Night Furies. But why didn't he see his own body?

As he tried his best to move his arms and legs to get a better angle, he jumped when he saw the new Night Fury moving as well.

I must have woken him up!

How could he have known that the release of a Night Fury when mating with a female was potent enough to turn any other species into a Night Fury for a day. And he'd licked copious amounts of that virile essence from Astrid's pussy after Toothless fucked her brains out last night.

The more he moved, the more he watched the Night Fury mimic his movements, the more he looked around him and found no sign of human skin, the more a suspicion began to form in the back of his scaly head.

What if?

He couldn't believe such a thing, the only reasonable explanation was that he was still dreaming, but deep inside he knew that he wasn't.

But where is Astrid?

Stretching his neck farther than he ever could with his human neck, he finally spotted something he hadn't noticed before. Just below the wooden bed lay something big, huge sparkling white wings shifting as she breathed deeply.

It looks almost like another Night Fury, but it's...white. A Bright Fury? No, that doesn't sound quite right...a Light Fury!

To confirm his suspicion, he tried his best to gain some sort of control over his new form, getting used to the new weight and dimensions of his limbs and the new muscles that supported them. It felt very strange to move so much mass with so much ease, at least once he got used to it, the most difficult thing to wrap his brain around was the fact that he had no way to stand or sit properly like a human. The most natural thing to do, which at the same time felt so unnatural, was to get down on all fours and hop, or in his case, tumble, off the bed.

Unsurprisingly, the loud thud awoke Astrid, who was quite disoriented herself at first as she tried to figure out why everything felt so different. Eventually, however, she managed to clear her mind and move her head to see what was going on. Her field of vision was surprisingly wide and the colors of the room seemed quite strange, but her main concern was the large Night Fury in front of her, which she recognized wasn't Toothless as his eyes were a cerulean blue instead of Toothless' emerald green orbs.

Only a high-pitched squeal escaped her throat as she tried to speak to the new Night Fury, who was staring at her awkwardly. Hiccup watched the Light Fury intently as she shifted frantically to meet his eyes and growl at him. He feared she would snap at him, but from the looks of it, she seemed just as disoriented as he was.

Her squeal startled not only him, but also Toothless, who awoke quickly, for the sound of another of his kind wasn't something he heard every day. He was all the more surprised to see two of his kind when he opened his sleepy eyes. His instincts made him carefully approach the foreign Night Fury and get a sniff of his scent, but for some bizarre reason this Night Fury smelt like his friend Hiccup.

Disbelieving his sensitive nose, he frantically circled the dragon, sniffing its scent like a German shepherd, but there was simply no doubt that this was Hiccup, even if his eyes contradicted that conclusion. In an attempt to break the tie, he decided to let his tongue decide who this dragon really was, and licked the dragon's neck and face lavishly, just as he liked to do to Hiccup.

Hiccup could only yelp as Toothless coated his face with his sticky saliva, unable to vocalize his typical complaints. The way Toothless reacted to his scent, the way he licked his face, made Hiccup realize he recognized him. The more he thought about it, the more the unbelievable reality of the situation began to sink in.

I turned into a Night Fury!

But one mystery was still to be solved.

Where's Astrid?

Looking around to make sure she wasn't hiding somewhere, he was once again reminded of the presence of that mysterious Light Fury, who was now the focus of Toothless' attention as he approached her to sniff her scent. Just like when he sniffed Hiccup, Toothless suddenly froze when he recognized her scent as Astrid's.

Intrigued by his reaction, Hiccup stumbled over to find out what Toothless had smelled. Not used to a dragon's nose, Hiccup was overwhelmed when he caught a whiff of her hide.

Oh my- It's Astrid!

Both Hiccup and Toothless had now realized what was going on, but Astrid was still looking at them with confusion and a hint of fear. Seeing her puzzled expression, Hiccup tried to find a way to explain the situation without words. He looked around the room for something he could use, but quickly realized that he couldn't use his quill with his paws, but maybe he could use signs.

He rushed to the top of his bed, or at least he tried to, and grabbed his Viking helmet with his mouth to drop it in front of Astrid. Looking at her even more confused face, he pointed first at the helmet and then himself.

Is this you, Hiccup? Astrid thought to herself as she tried to understand what the strange Night Fury was telling her. As much as she couldn't believe it, it would certainly explain the way Toothless acted around him, how he acted like it was his first day as a Night Fury, and why Hiccup was nowhere to be found. As a sign that she believed him, she nodded her head, much to Hiccup's relief.

As confusing as this situation was, they all realized there wasn't much they could do about it, so instead of freaking out, they tried their best to stay calm and enjoy this unique opportunity to find out what it was like to be the creature they so adored.

Still a bit embarrassed by the situation they were in, Toothless was the one to break the tension as he satisfied his own curiosity about Hiccup's new form by thrusting his sneaky head between Hiccup's legs to sniff at his virgin sheath. The unexpected contact sent shivers down his spine and made him jump in surprise, moans escaping from his mouth instead of the usual complaints about Toothless' inappropriate behavior.

Astrid chuckled as she watched Hiccup's reaction to Toothless' not-so-innocent sniff. After recovering from the initial surprise, Hiccup suddenly realized the full extent of his transformation, his heart racing at the prospect of finally finding out what it was like to have a cock as magnificent as Toothless'. Looking down at himself, his heart skipped a beat as he saw the tip of his draconic member protruding from his sheath.

Astrid couldn't help but watch it emerge as well, her own draconic pussy dripping as inch after inch of virgin flesh saw the light of day...or the stares of three horny dragons. The beautifully barbed head was covered by a thick layer of foreskin, large drops of milky pre-cum dripping from the several inches of overhang as the rest of the shaft was revealed. Similar to Toothless' member, several pointed barbs protruded from the lower tube, filled with a multitude of sensitive nerve endings that made them very fun to play with. The top was lined with a huge vein that fed dozens of smaller veins that ran all over his meaty flesh. The multitude of deep ridges was where most of the pungent slit fluids gathered, coating the entire shaft in a slick sheen of delicious juices.

Their heartbeats quickened as the last few inches of Hiccup's shaft finally emerged, his huge base revealing his full length being at least as long as Toothless', if not slightly longer. With all the attention on Hiccup, no one noticed that Toothless himself had fully unsheathed himself, but as he suddenly approached Hiccup, his huge shaft dangling from one side to the other, his intentions were obvious.

Positioning himself in front of Hiccup, Toothless did his best to move his member right next to Hiccup's, intrigued to find out which of them was the longest. To Hiccup's disbelief, he seemed to rock a few more inches as Toothless' tip was unable to reach his belly before his own belly was poked by Hiccup's slobbering tip. Hiccup warbled with pride as Astrid began to lose her mind at the sight of two virile dragonhoods touching, their fluids mingling as they rubbed against each other.

She rushed to their sides, squealing like a dragoness in heat, and immediately caught their attention when they saw what they had done to her. Her virgin pussy was gaping with need, gushes of fem juices leaking from her open vent to collect in a huge puddle beneath her. Since she'd just had her fill of Toothless' cock last night, it was only logical that Hiccup was next in line. And so he rushed over to her, just as she was eagerly rolling over on her back and spreading her hind legs to allow him to mount her.

Hiccup began by draping his forked tongue over her smooth opening, the intense stimulation to her sensitive clit causing her to whimper in pleasure. He repeatedly lapped at her dripping pussy, trying to collect as much of her surprisingly delicious juices as possible. Hiccup was used to her human juices, but the sheer viscosity and potency of her dragon fluids overwhelmed his even more sensitive taste buds.

It reminded him that with his new dexterous tongue, he might be able to explore her insides more thoroughly than he ever could. And so he did, pushing his viscous tongue between her wet folds, gently pressing them apart to be overwhelmed by the tastes and sensations as his tongue was massaged by her fascinating walls. Astrid's loud squeals rang in his ears as he circled his long tongue, making sure he'd lick every square inch he could reach. He could feel her powerful walls moving with his movements, as if trying to squeeze his tongue to provide as much stimulation as possible as he flicked it back and forth.

The sound of her cries of pleasure, the intoxicating scent of her heat, the exhilarating scene before his eyes was too much for Toothless to resist any longer, as his own dragonhood throbbed with need. Jumping off the bed, he hurried to her side and positioned himself over her, his rock hard one and a half foot member dangling in front of her snout. With her eyes closed tightly as she concentrated on Hiccup's ministrations, she didn't notice him at first, but when the unmistakable scent of his musky spike hit her nose, she quickly fixed her gaze on the magnificent organ that had just transformed her last night.

She drew out her forked tongue and gave the dripping tip a tentative lick before curling her deft tongue around it and pulling it into her warm mouth. Toothless growled as he felt his sensitive tip cradled by her forked tongue and guided into her wet maw. Knowing that she could probably take him whole with her new form, he slowly lowered himself and pushed inch by inch into her still tight throat. Astrid moaned around his shaft as more and more of it filled her throat, providing amazing stimulation to his sensitive flesh. Copious amounts of his pungent fluids pooled in her maw as he sank deeper, constantly bathing her significantly more sensitive taste buds in his intoxicating musk as she couldn't swallow until he pulled out.

Meanwhile, Hiccup couldn't hold back any longer and pulled his sloppy tongue out of her opening, repositioning himself until the hooded tip of his throbbing spire was pressed against her entrance. He took a deep breath of musky air before carefully pushing forward. Her virgin vent was tight enough to retract his foreskin as he pushed his head inside, the sensation of his never-before-uncovered glans being graced by her walls and bathed in her juices driving him wild with pleasure, his muscular hind legs quivering as he pushed in deeper. Both Astrid and Hiccup growled so loudly that the ground shook as they discovered the full extent of their dragon anatomies in unison.

Hiccup whimpered as he felt his cock squeezed tightly by her ridiculously strong walls, a clear sign that she was desperate for his precious seed. Astrid was losing her mind as the absurd girth of Hiccup's rock hard flesh spread her insides more than she'd ever experienced. Yes, Toothless' spire had already been a tight fit for her human vagina, but Hiccup's flesh was several inches thicker, stretching even her dragon pussy to its limits. And he wasn't even halfway in!

At the same time, both male dragons thrust inch after inch of their massive spires into her virgin holes, filling the room with deep, pleasurable rumbles as a sign of their intense satisfaction. Hiccup was already leaking enough pre, she'd lay an egg from his insane virility alone, and there was still more to come. He could still taste her juices on his tongue when it lolled out of his maw, as he felt more and more resistance with each additional inch he tried to bury in her welcoming depths. But with the help of his new, powerful muscles, it wasn't much of a challenge to sheath the thickest third of his member inside her passage. What was a challenge, however, was overcoming the mind-boggling sensation of the delicate barbs at his base slipping past her tight lips whilst the even more sensitive barbs at the head of his glans were repeatedly squeezed by her desperate walls.

Even though he had a lot more experience burying his shaft in tight places, much of which had been Hiccup's, Toothless had never experienced the throat of another of his kind around his magnificent flesh. Otherwise, he would've known how long and tight a Light Fury's throat was, and how much friction it caused in his most sensitive spots. He didn't even realize he'd reached his limit until he felt her scaly lips press against his own more intimate ones. Unable to resist his primal instincts, he slowly withdrew a few inches from her mouth, the tight grip of her throat on his head causing his foreskin to roll back over his glans, causing a huge glob of pre-cum oozing from his gaping tip. When he'd retracted about a third of the way, he suddenly stopped and thrust in again, but this time, instead of lowering himself carefully, he thrust rapidly down her well-lubricated throat. His musky slit collided with her maw as he bottomed out again, her flaring nostrils buried deep within his sheath, forcing her to fill her giant lungs with his primal musk as she breathed heavily.

Astrid's mind was utterly lost in not a sea, but an ocean of draconic bliss as the two loves of her life filled her from both sides, their monstrous cocks not far from touching inside her newly transformed body. The smell of Toothless' slit fluids literally filling her nostrils was so much more intense than she'd been used to with her puny human nose. She could pick up details and aromas that told her about his family, his age, his virility, and much more that she'd never noticed before, driving her senses wild with the magnitude of the new information. And if that wasn't enough, the copious amounts of that same liquid still bathing her taste buds with its pungent aroma ensured that she could never walk another day on this earth without tasting that virile male.

Only seconds after Toothless, Hiccup had bottomed out as well, his wet sheath lips now locked in a passionate kiss with Astrid's own. Desperate to give her everything he had, he continued to press his dragonhood against hers, his heart pounding as it filled his shaft with even more blood, swelling him to nearly two feet inside her. Even for a full-grown dragoness like her, such a monstrous length was simply too much for her vent, causing Hiccup's tip to kiss her cervix. A loud, primal growl erupted from his throat as his sensitive glans felt the contact and immediately recognized what he'd just hit. Astrid would have growled herself if her throat wasn't completely stuffed with Toothless' cock.

Having found his target, all Hiccup had to do was deposit his load and she would be pregnant with at least half a dozen eggs. With his entire mind focused on this very task, he didn't hesitate a second before quickly withdrawing about half of his cock from her immensely stretched opening. He groaned in agonizing bliss as his most sensitive parts were roughly grazed by her tight tunnel, her powerful walls instinctively squeezing his shaft in a vice grip to keep his life-giving organ inside her needy cunt.

Whilst Hiccup was just beginning to thrust in and out of her mouth, Toothless was already in a rapid rhythm, repeatedly filling her tight throat with his rock hard flesh. With each repeated thrust, he drew out another inch before plunging it back in again in the blink of an eye. His mushroom tip oozed copious amounts of potent pre as each thrust caused his frenulum to rub against the bumps and ridges of her hot throat, which squeezed his shaft as her instincts repeatedly tried to swallow the pooling fluids in her maw. Toothless eyes sparkled with pleasure as he watched her throat bulge with each thrust, allowing him to see just how deep he was going.

Astrid's vision began to blur as her only way to breathe, her nostrils, sank deeper and deeper into Toothless' slimy sheath, her entire face now covered in his most intimate fluids and her nostrils filled with his juices. If he didn't reach his peak soon, she might pass out from the sheer lack of oxygen. But for now, the mild asphyxiation caused her already incredible pleasure to reach record highs, thanks in no small part to the two incredibly hung dragons stuffing her with their amazing members.

Hiccup's own thrusts started out wild, but soon began to synchronize with Toothless' steady rhythm, whether it was psychic or perceptual didn't matter to him in the moment, all that mattered was filling her with his clutch. His sharp claws dug into the wooden boards beneath them as he retracted his cock almost completely before plunging it back into her, loud smacking sounds mixing with her groans as their slick scales collided with each forceful thrust. Hiccup was on the verge of losing consciousness as the indescribable sensations his new draconic cock was sending to his brain essentially drowned him in a sea of bliss. Though he'd often tried to imagine what Toothless felt when he stimulated his spire, the actual sensations he felt as his barbs were squeezed by Astrid's tight entrance, as his fist-sized glans graced her cervix, as his frenulum rubbed across her rippling walls, were simply unfathomable to his human mind.

Toothless, on the other paw, was "used" to these sensations, and yet it took all his stamina to maintain his steady rhythm of stuffing his breeding organ down her innocent throat, for his impending release was just as close as he was to losing his mind over her incredible throat. He hadn't anticipated how strong and vigilant her throat muscles were, squeezing his hard shaft in ways he'd never experienced before, causing almost unbearable friction on his most sensitive features as he released enough pre to completely fill Hiccup's largest mug. His maw hung wide open, his sloppy saliva collecting in a puddle beneath him as he sucked in rugged, musky breaths of air.

Even though Astrid's mind was effectively in another reality at this point, she noticed a strong, primal feeling hitting her brain, signaling that her orgasm was about to overtake her. Preparing herself for the impending climax, she gathered all her strength to grip their cocks as tightly as possible, making it impossible for them to pull out and not fill her with their fertile seed.

Hiccup yelped in surprise as his steady rhythm was suddenly interrupted by the vice grip of her muscular walls on his cock, making it nearly impossible for him to pull out of her tunnel. Some primal part of his brain recognized the sign and caused him to thrust as deep into her as possible, his tip pressed firmly against her cervix as a sudden rush of bliss flooded his senses. He felt his length fill with burning hot liquid as he realized he was cumming! Unfathomably violent spurts of potent cum erupted from his convulsing tip, bathing her cervix in his sticky goo as he roared so loudly that the people back in Berk could hear him.

As Hiccup filled her womb with enough seed for it to spill from her entrance, Toothless made sure to fill her from the other end. The almost painfully tight squeeze of her throat around his swollen member had triggered the same instincts Hiccup had experienced for the first time. With his final thrust, he pushed his cock so deep into her throat that half of her snout was now lodged in his slimy sheath, leaving Astrid breathless for the duration of his release. And what a release it was. His entire length filled with cum almost as fast as a bullet in a barrel, only to erupt from his pulsating tip with enough force to leave bruises if it hit human skin. Within seconds, her stomach filled with his breeding batter as he watched the violent spasms of his cock visible through her throat. Even after ten seconds of unbelievable bliss, his monstrous balls still had some juice left in them, which they gladly deposited into the belly of this beautiful dragoness.

Her own significantly more intense draconic orgasm would have been enough to make Astrid lose her mind, but to feel not one, but two virile dragon cocks erupt inside her, filling her with their hot, dense seed, was simply beyond comprehension. And as the seconds that felt like hours passed, her lungs began to burn from lack of oxygen. Her nostrils flared, desperately trying to suck in life-giving air, but instead of relieving her spasming chest, it only filled them with the pungent fluids in Toothless' sheath. Her new draconic body was strong enough to endure such a situation, but it didn't prevent the effects of asphyxiation from multiplying her pleasure with every passing second.

Eventually, though, even the massive balls of two Night Furies couldn't create matter and had to run dry, causing their pulsing cocks to release their final spurt as the half-minute mark passed. And yet, Hiccup had managed to fill every last inch of her womb that wasn't already occupied by his own rather voluminous shaft, as evidenced by the not-so-small puddle of steaming cum that now permanently stained the floorboards beneath her entrance. Toothless would have loved to leave his cock in this lovely new cock holster, but as the post-orgasmic clarity set in, he finally began to notice Astrid's spasming chest, which made him realize that her snout was still stuck in his sheath. Quickly flexing his muscles, he rapidly withdrew his spent shaft from her stretched throat, allowing her to take deep gulps of musky but still oxygen-rich air as she tried to recover from the most intense experience of her entire life.

Seeing Toothless withdraw his sloppy cock from her maw, Hiccup guessed it would be appropriate for him to do the same, so he straightened his stance before slowly withdrawing his massive spire from her still leaking pussy. He couldn't hold back a few pleasurable growls as his hypersensitive flesh rubbed against her amazingly still tight entrance as he pulled his spent shaft from her opening, causing a mixture of his cum and her juices to spill out and collect in the steamy puddle beneath them.

After a loud plop as his swollen head slipped free, Hiccup's big blue eyes marveled at the sight before him. Her beautiful lips were still parted, allowing him to see the mess he'd made inside her. Her walls were completely painted in the white color of his creamy cum as they shifted and gaped, almost as if they missed the presence of his cock.

The sight of Hiccup inspecting his work caught Toothless' attention, and he rushed over to his side to warble at his impressive first mating with a beautiful Light Fury. Another thing that caught his attention was Hiccup's similarly white member, which looked so deliciously covered in cum, slit, and fem juices that he just couldn't resist doing his best friend a favor and cleaning it up for him.

And so he just went for it, startling Hiccup as his delicate glans was suddenly enveloped by Toothless' lovely forked tongue, circling around every little barb until not a drop of cum was left on it. Continuing down the length, he extended his skillful tongue as far as possible, wrapping it around the girthy length. With the amount of grime and the sheer surface area, it only took a few inches before he had to withdraw his tongue and swallow their delicious mating juices. Hiccup squealed as he watched his best friend clean his dirty cock, not much different than the dozen times he'd done it in the past, but this time was quite different for he'd never experienced what it felt like to have Toothless' magic tongue wrap around a draconic shaft.

And what a difference it made. By the time Toothless normally finished his cleaning, he was still collecting the slime from the upper third of his shaft, where he was currently taking good care of the pointy barbs that lined the underside. For a moment, Hiccup thought about returning the favor, but he decided he'd rather let Toothless' cock retract into his sheath and let the grime collect there, knowing from experience that it was far more fun to stick his tongue inside the dragon's musky sheath and clean it that way.

Leaning his head back, Hiccup just basked in the amazing afterglow of this once-in-a-lifetime experience and let his best bud take good care of his well used dragonhood. Astrid was still panting heavily, her gut sloshing audibly with hot semen with every small movement she made, confirming her suspicion that she'd have to rest like this for at least the next few hours. Her mind raced with questions about how this could have happened, how long she would stay in this form, whether she would give birth to Hiccup's dragon babies, or whether she would give birth to a human baby if she transformed back in time, and many more. But for now, all she could do was rest and trust her best friends that no matter what happened, everything would be alright.

As she closed her eyes to drift off to a well-deserved sleep, Toothless was finally satisfied with his work, the only liquid still coating Hiccup's cock being his sticky saliva, his own belly now full of juices, though nowhere near as much as Astrid. Hiccup warbled in appreciation as he awkwardly watched his cock shrink back into its hiding place for the first time in his life before settling down beside Astrid where he snuggled up with Toothless as they watched over her and enjoyed the remaining hours together as dragon and dragon.
