Hiccup felt unbelievably giddy as he got back to town. Today he'd finally decided to test his new suit. There wasn't a word he could come up with to describe how it felt to be able to spread his arms and fly around like that. Riding on Toothless was still an amazing experience, but nothing could compare to the freedom he'd felt to be supported by wings of his own design. Toothless had been giving him some odd looks ever since he took flight. They'd spent most of the day out making one flight after another, only stopping when his arms almost gave out on him. Already, his shoulders and back muscles were starting to scream at him in agony. Stopping a second, he reached back to rub his shoulder.

The lad nearly toppled over when the dragon's head bumped into his back, Toothless voicing a low groaning noise. He laughed and rubbed the fury's head. "Alright, alright. Why don't we get inside where it's warmer?" The dragon nearly lifted him off his feet as he nuzzled into Hiccup's chest with a purr. "Just stay quiet, don't want to wake Dad up, do we?" The dragon gave him a playful nip and let his purring drop down to a bare whisper as they slipped into the house. Not that they really needed to be quiet. He doubted they could be heard over the thunderous snores, but he'd been surprised before.

Slipping into the house, he held the door open long enough for Toothless to slink in before he locked it tight. He darted through the house, feeling more than seeing Toothless virtually gliding along behind him. Hiccup only relaxed once he was in his room and had the door shut.

"I don't know about you, bud, but I'm ready for a good night's sleep." The dragon let out a wide yawn as he hopped onto the bed he'd made for himself, pacing around and blasting out some fire to warm the wood up before he laid down. While the dragon warmed his bed, Hiccup tossed a couple more logs onto the fire. They began to smolder for a moment, coals glowing red as if angry that he'd disturbed them. It was only when the new logs began to smoke that he moved away and stripped out of his clothing. Toothless lifted his head and watched as Hiccup slipped into his bed with a yawn. "Good night, Toothless."

Didn't take long before the human was off in dreamland. In his dreams, Astrid and he were laughing and flying around on their dragons. Round and round they darted, Toothless darting around Stormfly and nearly challenging the other dragon to mimic him. The dream shifted suddenly, Hiccup finding himself leaning against a tree with his pants around his ankles, Astrid kneeling in front of him with her mouth wrapped around his member. He moaned, grabbing at the tree trunk as her hot tongue wound around his cock, dancing over the shaft and teasing against his head. She looked up at him, smiling around his girth. As her head began to slide up and down over his cock, her features began to shift. Skin darkening as her hair receded. The changing Astrid purred around him, lips vibrating around his hammer. In only seconds, the human had shifted to look very much like Toothless, the dragon's eyes narrowing smugly.

Hiccup woke up with a gasp, sitting upright. A heavy paw pressed against his chest, driving him back down to the bed. The shove drove the air from his lungs, leaving him gasping for breath as a purr resounded through his groin. He lifted his head and hissed, "Toothless, what are you doing?" The dragon purred around him, head drawing back until his lips teased at his crown. He had to grab onto his bed sheets and clench his teeth to keep from groaning as the dragon teased him. The drake grinned at him, teeth sliding out just enough to nibble at his foreskin. Hiccup let out a nervous laugh as he looked at those sharp fangs, "C-careful there." He knew the nightfury too well by now, if the dragon wanted to do something then there wasn't much of anything that could stop him. Really didn't hurt that it felt so good either.

Grinning up at him, the dragon let his teeth come out more before retracting them. Pinching lightly with his gums, the dragon's tongue swept against his hard cock. With gums and tongue, Toothless gently pushed his foreskin back, exposing his tip. He tensed up as the tongue slid over his tip, each touch making his body jerk.

Those heavy jaws trembled against his length as the dragon's wide head lowered, easily taking in all of his length. Dark lips parted, hot air washing over his length. That wonderful feeling tongue slid over his length, down over his balls, and swept over his taint before coming back up. Laying on the bed, the dragon wrapped his maw around the human's shaft and balls, swirling his powerful tongue around both. Hiccup squirmed under that heavy hand, gasping and trembling as the tongue brushed over his tip. Toothless let out a soft slurp as he bobbed his head up and down, Hiccup's hips trembling against the motions as he grabbed at his bed sheets. Burying his nose into the human's groin, the dragon let his tongue slip out of his maw. The slick organ rubbed over his balls and down to tickle his back passage, all while flexing against the man's hard length.

Hiccup had to clench his jaw to keep from crying out from the strange, pleasurable sensations that his dragon was giving him. He clenched his jaws and huffed as the tongue rolled and rubbed against his cock, the tip of the slick muscle easing into his rear. Mouth fell open in a soundless gasp as his hips trembled, knees bumping into the dragon's chest as his partner worked him over. Hips jerked and rocked up towards that hot, eager maw. He had to bite back a groan as those soft gums, protecting him from the male's sharp teeth, slid over his cock and moved up to teased at his tip. His dragon's powerful tongue curled around the cock and stroked it, milking the seed from his depths. Toothless looked up at him with a smug purr, head wiggling just a little to change how it felt around Hiccup's cock. Not that the dragon had to work that had. It took less than a minute from the time he started until the human's body jerked and he stifled a cry into his own wrist as he came long and hard.

Toothless kept his muzzle buried into the human's groin as he let the cum pool in his mouth before swallowing it all with a gulp. The dragon pulled back with a slurp, smacking his lips happily. Hiccup dropped to the bed with a pant, head reeling as he laughed. "That was unexpected, but thanks bud." Reaching out, he rubbed the dragon's head appreciatively. "Why don't we get some sleep while we can? Got a busy day of training tomorrow you know."

He reached for the blankets to pull them up as Toothless shifted on the bed. In the dark of the room, Hiccup failed to notice the flash of red hanging from the male's groin. A forelimb stroked down his side before lifting the human's rear up. "Toothless, what are you doing?" he hissed, squirming against the male's powerful form. The dragon purred and wiggled against him, eyes glimmering in the dull light coming from the fireplace. "What? Do you want to cuddle in bed, play, are you hungry?" Teeth flashed as the dragon grinned at him. Oh, the nightfury was hungry for something alright. Just not what the human was used to him having a hankering for. "I'll get you some of your favorite fish tomorrow if you calm down." Hiccup moved his legs to wrap around the dragon's bulk as he'd done dozens of times before to cuddle with his friend.

This put him in the perfect position for the drake. Hiccup frowned as a strange warmth traced up his thigh. "What is that?" he asked curiously and titled his head. Whatever it was it was really hot and hard, but was fairly slick as well. Almost felt like his cock when he teased himself... oh no! "Toothless, what are you doing?" He hissed, pushing at the male's chest. Toothless's body rumbled with a purr as his cock slipped between Hiccup's cheeks, rubbing over his taint and up to his balls. "Toothless, no!" He grunted as he pushed at the male. The nightfury tilted his head and let out a curious purr, hips shifting just a bit. Hiccup breathed a sigh of relief as that cock slipped down without the pressure of the horny male to keep it grinding against his privates. "Yes, no. Now, just lay down and get to sleep." Toothless snorted at him and rocked his hips quickly. Hiccup jerked and clenched his teeth as the male's cock probed his backdoor.

Between the dragon's precum and the licking earlier, it was fairly easy for the pointed tip of his cock to press into that virgin pucker. Hiccup grabbed at the male's shoulders and buried his head into the dragon's powerful neck as his ass was spread wide by his partner. Panting, he held tight as his head reeled from the strange sensation. He buried his face into his partner's neck as Toothless pressed forward slowly. The sensation was like nothing he'd ever felt before. Oh it hurt, that much was obvious, but there was also a strange pleasure that was creeping up on the heels of that ache. Toothless's purr rolled over him as the male hooked his thighs under the human's.

His head was reeling as he breathed in the dragon's strong musk. "To-toothless, wh-w-what are you..." he swallowed, "doing?" The drake rolled his eyes and mocked his question with grunting noises. He supposed the answer was fairly obvious. The sleek form rolled smoothly as Toothless drew back. That member twitched as precum rolled up his tip, making it easier for him to push deeper into his partner. His next plunge drove him deeper into the human, his tail thumping against the bedframe as the tight muscle clenched around his cock.

Kneading his friend's shoulder, Hiccup's cheeks flushed hotly as he shook under the dragon. He licked his lips and leaned back against his bedding. There was no escaping it, he guessed. Might as well try to enjoy if it he could. "Okay. Go on, but keep it quiet, okay?"

Toothless nodded his head with a grunt. He drew back and gave another buck, drawing a grunt and a hiss from Hiccup. More precum came from his tip, making his thrusts run a bit smoother. The human huffed and grabbed at the bedding as his rear throbbed around the pole. Toothless rolled his head and breathed out a pleased groan as he began to rock his hips. Hiccup tried to hush his friend, but the dragon was picking up his pace the deeper he got. Any words of protest that the teen had were turned into low groans. The pain faded to the background as that precum made the dragon's cock slide easily in and out of his rear.

A triumphant purr rattled up the dragon's chest as his groin smacked against Hiccup's rear. Toothless arched proudly, pushing Hiccup's shoulders down into the bed as he half-stood, making the human's rear lift higher. His purr turned into a low growl as he arched his body upwards and began to fuck the human with short, powerful thrusts. The study bed barely creaked under the creature's frantic rutting, but Toothless's tail cracked against the wood and floors as he breathed out a throaty groan. Hiccup grabbed at the dragon and the bedding, his cock rock hard and aching as his partner fucked him like a wild animal. He tried to tell the dragon to quiet down. Tried to signal the male to slow down. Something, anything. There was no stopping the dragon though. Pleasure filled growls and groans filled the room, competing with the sharp crack of his tail against everything around the room and the firm smack of groin on tender ass. Hiccup finally let out a moan of his own, precum dripping down onto his belly as the dragon rutted him.

Toothless froze mid thrust, ears lifting. Twisting his head around, he looked over at the door, ears twitching. With a surprised snort, he dropped his full weight onto Hiccup a second before the door opened. Stoic opened the door and looked in, "Hiccup, what is going on in here?"

Hiccup's cheeks flushed, thankfully hidden under the dragon's bulk. "Nothing Dad. Toothless just decided that it was a great time to drop down and play a round of bite the human." The dragon nodded his head and twisted to slobber on Hiccup's head, making him sputter and wave.

The village chef just grunted, eyes heavy. "Just keep it quiet as you eat my son, alright?" Toothless grunted a confirmation and wiggled down on top of Hiccup, chewing at his head playfully.

Head twisted as the door creaked shut and latched. Toothless kept his mouth wrapped around Hiccup's head for a moment long before releasing the male with a churr. Looking down at his partner, he grinned as he drew his hips back nice and slow. His chest rattled with a purr before he dug right back in with renewed vigor. Hiccup grabbed at his chest and huffed through clenched teeth as the dragon's body smacked and drove against his hard and fast. Hiccup buried his head into Toothtless's chest as his body shook as he began to cum. His tightly stretched rear clenched around the cock, drawing a soft groan from the drake. Hips drove hard against his as the dragon tried to hold back from hissing and growling, not wanting to Stoic down for another distraction and keep him from his fun.

Something strange was happening down below. Toothless was barely moving his hips with each thrust, smacking his groin against Hiccup's tender ass cheeks. He could feel something start to swell and press against his insides as the males groaned. Hiccup's nails scraped at the dragon's hide as that pressure built against his insides. A low groan came from the dragon as his thrusts shortened even more, hips smacking quickly against his rear and thighs. That pressure built as the male's knot held tight inside of his body. Hiccup buried his face into the male's hide and breathed out a moan as he hit another peak, his third for the night! Usually he was pushing it to get two out of himself. Although before he'd gotten as many as five out in a night, but that'd been a while.

Although it seemed like two would be his limit for tonight as well. No sooner did he start to make the mess on his belly even larger, did Toothless breathed out a hissing growl. Jaws snapped and latched onto his headboard, the male snarling into the wood as he came hard into his human partner. Molten hot cum filled Hiccup's rear as the dragon bucked his hips quickly. His fat knot pulsed with each spray of his cum, filling Hiccup right to the brim.

Prying his teeth from the wood, Toothless licked his lips and shook out his head with a low purr. Eyes began to drift as the male lifted his body and tugged at his hips. Hiccup gasped as the male's knot tugged at his rear. He'd seen dogs breed before and had an idea of what it was, just never thought he'd experience it firsthand. Toothless tested the tie with a couple short pulls before shrugging and just dropping down on top of his partner. Hiccup gasped at the male's weight, petting over the dragon's sides as Toothless vibrated with a low purr. "Heavy oaf," he huffed. The dragon rolled his head and let out mocking noises before wiggling down being trapped under the male was a good thing in that he wouldn't need a blanket tonight. Although, he was pretty sure he'd be walking funny come morning.

And did he ever. Riding the next day had been hard. Toothless seemed energized, eager to pull more stunts and tricks than they usually did, diving and swooping faster and ranging further. Even without the nightfury's odd behavior during the night, the rider would have been sore and limping. As it was, he could barely walk when he headed for the great hall for food. Astrid waved at him and smiled as she came over with food. The fellow dragon rider slowed when she was a few feet away and looked him over. "What happened to you?"

Hiccup gave a shaky smile as he sat down very slowly. "Oh nothing. Toothless just kept me up all night and then decided to pull off a few new tricks today without warning. Can barely walk right now."

She laughed, "Yeah, Stormfly has been acting a little odd too. Might be getting around time for the dragons to go and make some eggs, if you know what I mean."

Eyes widened knowingly, "Oh..." His cheeks flushed, "I hadn't even thought of that. I mean, we haven't really experienced this stuff too often have we?"

"Gonna go start taking notes and stuff? See if Toothless's ram starts to come down if he's ready to storm any other dragon's gates?"

His blush spread a bit more as he let out a nervous laugh, "As much as I'd love to record notes on all that, I'd rather give him his privacy with that. After all, wouldn't want him following me around when I go courting do I?"

It was her turn to blush now, coughing into her mug. "No! I mean... No, of course you wouldn't." She pushed her food around for a moment, "I've got something to help for bruises, you know. Got it worked up for when Stormfly decides to run a bit rough. Helps with bruising and soreness." She gave a knowing smile at him, "Could even help you work it in some if you want. "He looked at her and began to smile as well, loins stirring at the very thought of it.

Hiccup stomped into his room, snow sticking into his hair and face red. Toothless perked up from his spot on his stump with a curious noise. "It's nothing, Toothless. Just opened my big mouth and shoved my foot right into it again." The dragon chuffed out a laughing noise and laid down again. Hiccup dropped onto his bed and worked off his boot with a huff. "So Toothless, question." An ear lifted up slightly. "What was all that last night?" The ear dropped and the male let out a snoring noise. "Just gonna pretend to be asleep now?" The male let out a snoring noise and wiggled down. "Yeah, guess you are." He dropped flat onto his bed and groaned as soreness radiated from parts he didn't know could be sore. "Typical for a dragon." Toothless's head wiggled as he let out mocking noises. "Yeah yeah, Arrrharrhra." Hiccup growled back at his friend. Eyes started to droop as he lay there, the day catching up with him. For a moment, he thought about just going to sleep right where he was. However, he never liked sleeping in his clothes, and had the feeling that if he did then Toothless might just find it necessary to strip him down if the urge to repeat last night's antics struck the drake. As much as he feared that Toothless might want to try it again, he feared the loss of his clothing more. With a sigh, he stripped down and slipped under the covers. Looking over at Toothless, he saw that the dragon showed his typical lack of interest in most things Hiccup did. At least the things that didn't involve flying or eating. Curling up under the covers, he breathed out a contented sigh as weariness claimed him.

Not that he got much rest. Every noise, each bump, those little scratches, and the creak of wood made his eye snap open. Hiccup sighed and rolled onto his back, looking up into the darkness of the ceiling. Rolling his head, he looked towards the stump that his dragon was sleeping on. It was easy enough to pick out the darker shape of the nightfury, a shadow among shadows. Toothless shifted in his sleep, a glimmer showing under a partially open eye. The dragon uncurled slowly and looked at him with softly glowing eyes. Hiccup quickly buried his face into the blankets, wanting to avoid that gaze. Even with several layers of blankets, he could feel the gaze burrowing into him. Very slowly, he pulled the cover down and looked up.

Toothless had curled up again, head tucked under a wing as he breathed softly in his sleep. He laid down very slowly and resumed staring at the ceiling. He shuffled under the bed, going through one sleeping position after another. No matter how he laid or how the covers were arranged sleep stayed just out of his reach.

After who-knows how long, he finally sat up in bed and threw the covers back. "Toothless?" The ear twitched at the whisper. Hiccup watched the dragon and let out a sigh, "Can't get to sleep, can you?" A grumble came from the dragon as the male wiggled. "About last night..." he trailed off, rubbing his fingers through his hair. At the mention of the night before, the dragon sat up and looked at him, his expression perhaps a touch too eager. The Viking let out a sigh and waved at his lap, "Just keep it quiet, okay?"

Toothless breathed out a purr that almost sounded like an agreement as he oozed off his stump and over to the bed. Wood creaked under the male's weight as the dragon joined him. That wide head nuzzled into his neck as the dragon breathed in his scent. His purr rolled over the human's smaller frame as his head lowered slowly. Despite the aches from the previous night and the apprehension that'd been rolling around in him all day, Hiccup felt his excitement stirring. Breath started to come in shorter huffs as the dragon's hot breath washed over his bare form. Resting a hand on the drake's neck, he breathed out a groan as Toothless sniffed over his cock slowly.

Rolling his head, the nightfury looked up at him with a smug expression as he opened his mouth slowly. His forked tongue slipped out to curl around the stiff cock. Hiccup gasped at the feel of that hot muscle as it slithered around his meat. That skilled muscle danced over his cock, the forks wrapping around it and hugging his member before drawing it upwards. Rolling his head, the dragon pushed his body back even as he closed gentle lips around the cock. That broad head rolled slowly, gums gently teasing his head before sliding further down. Jaws vibrated against his tender flesh as Toothless buried his nose into the human's lap. Lips sealed around his base as the dragon swallowed against his flesh. Back arched against the headboard as he let out a deep groan, eyes rolling in his head.

Nails scratched against the dragon's scales as his hips lifted. The night before, his panic had lessened his pleasure. Now that he'd invited the dragon over to play with him he could enjoy the full force of the male's skills. Hips jerked as he let a hiss trickle out of his lips. The dragon nuzzled into his lap with a purr as that cock began to jump and pump his load deep into the waiting mouth. Paws kneaded at his thighs as the dragon's tongue rolled against his flesh and coaxed out every last drop that the Viking had to offer. Those wide, expressive eyes narrowed with a deep purr as the dragon rolled his head this way and that, tongue drawing over his flesh each time it jumped. His dragon stayed down until he was certain that he'd gotten every last drop of that thick Viking cream.

The drake pulled back and licked his lips, shuffling his feet back and forth a bit. Hiccup let out a soft laugh, still reeling from his orgasm. "I guess it's only fair. Just be a little gentler tonight?" Toothless nodded and started to do the same eager little dance he did whenever Hiccup was holding onto one of his favorite fish. Biting his bottom lip, Hiccup shifted on his bed. Growing up in the village as he had, he'd seen plenty of animals mating. And, as it turns out, dragons weren't too shy about making a display when they needed a little sex either. Often having their loud, fire breathing romp right in the middle of town. Since most of the wings being preferred it this way, he figured that Toothless would as well. Sliding his knees up, Hiccup grabbed onto his pillow and let his chest and face rest against it.

An appreciative purr rolled up the dragon's throat as Toothless curled around him. His head nudged against Hiccup's rear. Hot breath washed over his body as the dragon sniffed at him before licking over his tender flesh. A heavy forepaw came down on his rear and spread his cheeks just a bit. Hiccup bit his lower lip and shivered as that burning tongue danced over his balls before tracing up his taint nice and slow, teasing him. Toothless breathed in his scent as he eased a tongue fork against the Viking's back gate. He worked in one fork and rolled it nice and slow, making that sore ring relax slowly. The second fork danced and twirled against clenching muscle before tenderly sliding into the rear as well. The feel of that slick, gentle muscle ease him into it. Hiccup let out a shuddering breath and pushed back against his friend.

Toothless knew the signs of a ready partner when he saw one. He gave Hiccup's rear one more nuzzle before walking over the human. Eyes narrowed as he breathed out a rattling purr at the feel of that so-soft skin rubbing against his scaled belly. That tender form tremble under him, but pressed against his silken scales as he slid over him. Hips rocked as the dragon brought his form closer to the Viking. The tip of his spear jabbed here and there, spreading his precum against that oh so soft skin. Licking his lips, he arched his body proudly and purred as he slid that hotness between the male's cheeks. Glancing downward, he watched as that red member slipped and slid over the ass cheeks, precum making the length glisten. "Let me help you there, buddy." He angled his head as Hiccup reached back to grab his cock. The dragon smirked as he felt that hand trace over hi cock for a moment before guiding his tip down. Looked like his rider was a bit too eager to be ridden. Ah well, he couldn't tease humans too much now could he? Frail things couldn't handle fun the way another dragon could. Oh well, he wasn't gonna make his partner wait too much now.

The tip barely touched against his pucker before Toothless pushed forward. Between his prep work and the amount of pre covering his length, it was easy enough for the dragon to feed his length into the human's tightness. Toothless breathed out a quiet snarl as his groin smacked into that upturned rear, driving Hiccup forward. His friend had to bite on his lower lip to hold back a moan, eyes shutting tightly. Arching his body, the dragon planted both forepaws on the carved headboard, stepping his hindfeet apart. Tail snapped behind him as lips peeled back in a silent snarl as his hips rocked against the upturned ass.

Jerking back, Toothless powered forward, smacking his groin into the Viking's tight ass. Claws scratched at the wood as he began to thrust firmly, fucking the human with increasingly powerful strokes. Even as he got rougher and harder, he kept a watch on his partner to make sure that he didn't push things too far. Last thing he wanted would be to break his human too hard. Had to break him just enough to train him properly.

Hiccup buried his head into the pillow and moaned as Toothless pounded into his ass. Hips arched and lifted back, driving into the dragon. His cock was rock hard already, swaying with each of the dragon's thrusts. Toothless's massive balls, a pair of maces contained in a silky pouch, were slapping against his. Hiccup groaned into his pillow, tightening his grip on the pillow as he arched and pushed into the feral male. Between the dragon's thickness and the odd shape of his length, he felt his pleasure building up quicker than it ever had when he took matters into his own hands. Cheeks flushed bright as he breathed out a groan, precum dripping to his bedding as he arched and rolled. Broad head dipped to nuzzle into his neck, licking over his form as Toothless growled out a pleased moan. A blue light rolled from the dragon's mouth as his pleasure grew.

Powerful body pressed tight to his backside, that half-formed knot easily popping into the human's tight ass. Hips jerked up and back as that heavy male pressed down against him. Hiccup had to bite down on his pillow to keep from calling out as that knot grew in his ass. Each time Toothless's body smacked against his, that bulge grew fatter and fatter. It was only a matter of seconds before they couldn't pull away from each other, the knot keeping them together. It continued to grow and swell, stretching his inside nice and wide. Hiccup jerked back and cried out as he started to cum, spilling his seed onto the bedding. Tight muscles clenched and squeezed around the dragon. Toothless closed heavy jaws onto his shoulder, soft gums pressing into his flesh as the male let out a muted snarl. Burning hot cum blasted against his insides as the dragon pumped him full of his thick cream.

Collapsing into the bed with a huff, Hiccup felt the world rolling around him as that lovely cock sprayed the dragon's virile load into his backside. Toothless broke the hold on his shoulder with a purr, licking over the forming bruise with an almost apologetic trill. Stretching his form out, the dragon gave a shake before simply dropping to his side. Hiccup gasped as he was jerked onto his side, that knot keeping his body trapped against the dragon's form. A deep purr rolled over him as Toothless wrapped arms and wings around him. He gave a shaky smile and pressed himself back into the warm body. "Good night, bud." Toothless mumbled out something that sounded similar as he snuggled up close.

Morning came far too early. Despite getting, what he was sure was, no sleep, he felt oddly refreshed. His father woke him with a thunderous call and banging on the door, making him jerk away from the dragon. He'd barely had time to get his pants on before Stoic came in and declared that he had lessons for him. Toothless let out a mocking laugh and wiggled into the covers as he was hauled off by the village chief. Regretfully, he was made to spend almost the entire day with his father. He'd seen Toothless hovering nearby a few times, but the Chief wasn't letting him have any chance to slip away with the dragon. Just one too many times of being gone for hours or even days at a time as he and his bud explored. Even with how busy he was kept during the day, first with his father, then Gobber, and finally Astrid, his mind kept roaming back to that sleek dragon.

Night was falling before he managed to stagger back home. Toothless was back on his stump, snoring as he dozed. Ears perked up as Hiccup came in and slammed the door. Eyes opened as the drake gave a grumbling growl. "I'm sorry, did I disturb one of you many naps, oh great dragon? How can I possibly make it up to you?" The great head lifted as the dragon gave him a sideways grin. He let out a laugh, "Oh of course that's what you're interested in isn't it?" Toothless sat up, the male's red cock already peeking from his slit. Cheeks flushed as he saw that, feeling a strange stirring in his belly at the sight of that member. He moved back to the door and made sure it was firmly latched and secured before starting to strip off. The nightfury let out an open-mouthed appreciative purr as the Viking undressed for him. "I certainly hope you approve, seeing as how you've been lusting after it."

The dragon hopped off the stump as he dropped the last of his clothes to the ground. His broad head nuzzled into Hiccup's lap with a purr, nose bumping his privates as he breathed in the Viking's scent. Hiccup pushed at the head, "Hold on a second there, bud. I wanna try something different." Toothless let out a curious trill as he angled his head.

Hiccup felt a nervous flutter as he stepped around the dragon, hands petting over Toothless's hide. A soft nudge was all it took to roll the male onto his side. Reaching under the dragon, Hiccup ran his fingers over the tip of the male's cock. Toothless purred and heaved onto his back at the touch, offering himself up fully to the human. The sight of that cock, standing out against the dark hide as it was, sucked in all of his attention. Climbing onto the dragon's belly, he straddled his friend and laid on top of the male. Toothless's body vibrated under him in a way that felt oh so good. Cheeks flushed brighter as he felt those rumbles roll against his cock, which was nice and hard as it pressed between his body and the dragon's.

Reaching out, he curled his fingers around the male's hot rod. This was the first time he'd actually gotten a good look at it. Stroking the shaft, he let his fingers ripple across the raised ridges that spanned the length of the dragon's underside. He traced a couple of them, feeling how they flared just a touch as his finger teased over it. Tracing his way down to the base, he felt over what was the male's knot. Right now, it didn't see much different from the rest of the male's length. Just a small little bump on that lovely length. He knew what it'd feel like when it got bigger though, and felt his rear clench at the mere thought of how big that thing felt. Well, provided Toothless behaved, he'd get to see how big it actually became.

Holding onto the base, Hiccup leaned in and ran his tongue over the tip of the cock. He'd tasted his own seed before and even once, after a very strenuous session of contorting, managed to lick his own cock. The dragon tasted far different from his own salty spire. There was still that heavy flavor of salted essence there, but the overwhelming flavor was a lovely spice that tingled along his tongue. Leaning in, he pressed his lips to the tip softly and suckled on it just a little. Toothless arched and let out a soft groan, legs twitching as Hiccup pressed forward slowly. Lips spread around the dragon's cock as he fed the spiced meat into his mouth. Moving very slowly, he pushed down onto the cock until he had to pull back, the tip jabbing against his throat. He pulled back quickly as his throat rolled in a gag. Taking a deep breath, he started to stroke the cock as he bobbed his head.

Toothless's body vibrated with his purr as the male laid his head on the floor, feet kicking happily at the feel of a mouth around his cock. Hiccup moaned at the increased vibrations, rolling against his friend's body. Precum coated the dragon's scales, making his cock slide over them. Tightening his thighs against the male's trunk, he closed his eyes and began to bob his head faster over the length. He kneaded the male's base, feeling that knot already growing against his touch. Ridges flared and popped against his lips as his he bobbed. Salvia coated the length as he pressed his tongue against it, tasting that tingling spice. A groan came from the dragon as those hips bucked upwards, driving his cock that much deeper into the waiting mouth. The partners began to work together, Hiccup rolling his head as he worked over that thrusting member. Reaching back, he ran his fingers over the dragon's heavy balls, feeling them churning with the male's heavy load.

A particularly firm thrust sent the cock jabbing against his throat. Stomach rolled as Hiccup pulled back with a gasp, salvia connecting his lips to the member as he gasped for breath. Despite how his stomach rolled, Hiccup dove right back in on sucking the heavy member. There was something about the dragon's taste and scent called to him. It sang to him, urging him to draw out more and experience the male's full flavor. His eyes were partially lidded as he stroked the male's cock and balls, lips burning as they stretched around the thick length. As he watched, that thick knot grew and pulse with each beat of the dragon's heart. Abandoning the balls, he wrapped both hands around that bulge, kneading it as his head bobbed quickly. The knot ballooned against his touch, fingers hooking behind it as the males shared a groan.

Toothless jerked his hips and growled, gritting his teeth as that knot pulsed against the grasp. Hiccup's moaned at that first blast of molten cum as it sprayed across his tongue and down his throat. He watched the length as it sprayed, filling his mouth with the dragon's spiced cream. Hiccup held it in his mouth for as long as he could before swallowing it down with a heavy gulp. Moving his hands, he stroked over the knot, toying with it each time it throbbed, pumping another shot of the male's spunk into his mouth.

The dragon's climax didn't last nearly as long in his mouth as it had in his rear. It was only a matter of moments before the male was softening and slipping back. Hiccup sat back and licked over his lips with a huff, cock as stiff as an iron post. Toothless looked at him with a grin, a deep purr rattling through the Viking's body. The male arched off the ground and heaved over, dumping his rider to the ground. Hiccup tumbled to the ground, expecting the dragon to pounce him at any second. Knowing his dragon and the way he'd been acting, he'd probably bat Hiccup around for a second before mounting again.

When the strike didn't come, he sat up slowly and looked towards the drake. Toothless looked back at him with a grin, hips wiggling as he swung his tail up and to the side. Moving over slowly, Hiccup ran his fingers over the dragon's hips. Thick tail swing up and to the side as the dragon presented himself to the rider. Hiccup licked his lips slowly and looked at the male, only just able to pick out some details in the dim light from the fire. He recalled the way Toothless had played with him the night before, getting him ready. As ready as he'd been to wrap his lips around the male's cock, there was something not entirely thrilling about playing with the male's anus. Still, his friend had been more than eager to please him, so it was only fair that he return the favor. Wasn't it?

Breathing out a little sigh, he leaned in and licked over the male's musky balls. Toothless breathed out a groan, rear wiggling eagerly. "Shhh, Toothless." He hissed as he rested his hands on the male's body. The dragon grumbled, but kept looking back at him as Hiccup licked over the weighty balls again. His tongue swept over the heavy sac and up towards the male's spread slit. His tongue slid along the slit before pushing past the dragon's folds. Hiccup blinked at the odd flavor and wetness that he found there, pulling his head back. He blinked and leaned in again, licking over the dragon again, drawing a moan from his friend. There was something odd about the taste, something very close to the taste of the dragon's cock, but strangely different.

"Just a second, Bud." The dragon breathed out a curious trill, tilting his head, but stood there as Hiccup went to retrieve a candle. Lighting it from the fireplace, he returned to his dragon and sat back down. Bringing his light up, he spread open the dragon's slit and found himself blinking in confusion. Right there, inside of the dragon's folds and behind his balls, was what looked like a female slit. Ruby lips glistened with moisture and spread under a gentle probing. Toothless's hips jerked back as he voiced a warbling croon. "Toothless, shush. You're starting to get too loud. "He licked his lips nervously and looked at those puffy lips and warm insides that squeezed at his fingers. Despite his warning, the dragon continued to vocalize, hips jerking back against his fingers.

Toothless let out a whimper and looked back as Hiccup pulled his hand away. When Hiccup moved to sit on the bed, the dragon looked downright offended, growling as he sat down heavily. Hiccup blinked at his friend and thought for a moment. "Tell you what, Toothless. Let me make it up to you." The dragon snorted and turned his head away. "We can get our bags and stuff, and in the morning we can head out. Remember that island we found a few weeks ago? The one with that lovely bluff and the hot springs?" An ear twitched. "We can go out there and spend several days out there. It's warm enough that I won't even need clothes." Toothless looked back at him curiously before looking away with a snort. "Several days, just us, and we can do whatever we want." The head swung around as the dragon breathed out a curious purr. "Yes. Anything, anytime." The nightfury twisted around and leapt at him, pinning him to the bed as he licked over Hiccup's face, making the human laugh and press at the head. "Okay okay. Just settle down for tonight, okay?" The dragon purred an agreement and just dropped down on top of him, pinning him to the bed. Hiccup grunted at the dragon's weight, but accepted it, stroking that lovely head as he stared up at the ceiling until sleep claimed him.

Hiccup woke first, eyes snapping open as he bolted awake. Toothless lay half-curled around him, a purr rattling up the dragon's throat as he nuzzled Hiccup's bare chest in his sleep. Fingers brushed over the dragon's cheek as he whispered, "Toothless?" An eye cracked open inches from his face, looking at him with a silent question. "Ready to head out, or do you wanna wait a bit?" The dragon grumbled and stretched his jaws in a wide yawn, striking the Viking with his powerful morning breath, before slinking off the bed. A nervous flutter danced around Hiccup's belly as he got his clothes on and gathered up some gear. Habit meant that he could get ready to fly in a matter of moments. He kept looking over to Toothless, dozens of questions roaming through his head about his dragon. Seems like every time he felt he knew everything about his companion, something would happen that'd throw his understanding right out of the window. What he'd found last night was definitely one of those finds that he probably wouldn't be putting down in the books anytime soon.

The sun wasn't even up when the two of them took to the skies. Hiccup breathed out a huff and leaned down close against Toothless's form to ward off the cold. His partner's warmth soaked into his body, relaxing him in a way that nothing else could. As Toothless pumped his wings and took them higher into the airs, the cold faded away, leaving Hiccup with the simple exhilaration that always came with the act of flying. Breathing out a contented sigh, he ran his fingers over his dragon's scales. He didn't even have to watch how they were flying. He knew deep in his bones how to move and react with the dragon's flight. Leaning here, shift his foot there, everything was like a dance as the drake soared through the air.

It wasn't long before Toothless started to bank and sweep towards their destination. The flight was both over too fast and had taken far too long. Hiccup's stomach began to roll with nerves as they approached the rich, soft grass. The pair worked together as the warmer air from the hot springs buffeted them. Hiccup huffed as the humid warmth rolled over his body, a purr rumbling up from Toothless's body as he breathed in the mineral rich air. The drake was almost dancing as he set down, head snapping towards the plume of steam rising off a nearby pool. "Alright Bud, let me get the packs off you and you can go for a swim." The nightfury breathed out a warbling noise and bounced a bit, drawing a laugh from his rider as he worked the saddle straps loose. "Toothless, would you calm down?" He was bounced as he worked the straps off, getting thumped by the male's body several times before he got those chest bands loose. "Okay there you g..." the dragon knocked him flat, worming out of the saddle with a squirm before bounding across the grass. Hiccup laughed and shook his head as he hauled the bags to a shallow cave he knew of. It was just large enough for him and Toothless to set up camp and have a bit of room to get out of the weather if it turned bad. Last thing he wanted to do would be to cut their little vacation short and return home before they were both ready.

Just thinking about why they'd come out here invited another nervous jitter to dance through his stomach. He hadn't forgotten about why they'd taken this trip, but he had put it out of his mind for a moment. Now though, he could only think about what he'd seen the night before. Those luscious ruby folds tucked away inside of those dark lips. Even in the firelight, the moisture on those petals glistened like jewels, tempting even the most honorable of men. Deep down, Hiccup knew that he probably shouldn't be doing this, but he'd already taken it this far with his partner. So what would be the harm in taking it just a couple steps further?

As if summoned by his thoughts, the dragon slinked into the camp with a low purr. His hide glistened with the water from the springs. "Didn't soak too long?" He reached out to rub the dragon's head, prompting deep purrs from the male. Toothless nudged his head into Hiccup's chest and rubbed him with a deep purr. That rubbing head rolled against his chest before lowering with a deep huff. His nose nudged against Hiccup's groin, the male snuffling at his lap. Normally, he'd just say that it was something about the springs that got the dragon riled up, but that paired with how he'd been acting the last couple days meant that he'd better take off his clothing before Toothless decided to. "Okay, okay." He ran his fingers under the dragon's jawline and lifted the head. "Give me a minute to undress, okay?" A purr rattled up Toothless's throat before the male let out a fishy burp. "Lovely, thank you for that."

Getting undressed was a matter of seconds. Thankfully, for once, Toothless didn't try to help him with the task, as he'd done before. Instead, the nightfury sat back on his haunches and breathed out a purr. Hiccup's cheeks flushed, "Do you have to watch?" The dragon nodded and gave his crooked grin, making the Viking laugh. "You're just a massive pervert aren't you?" Toothless grinned, tongue rolling out of his mouth. All it took was a glance down the male's sleek form to reveal that his member was peeking out of his slit, firming up even as Hiccup neatly tucked his clothing away in a pack.

There was that nervous flutter again. Pushing it to the back of his mind, Hiccup approached his dragon. "Okay, same as last night, Toothless?" The dragon purred and arched, watching as Hiccup dropped to all fours and lead under the male. He'd only gotten a whiff of the dragon's scent before the male leapt to his feet and bounced away. Confused, Hiccup sat up and looked at his dragon. Toothless turned a couple circles before stepping his hindlegs apart and swinging that tail up and to the side. He dropped his head and looked under his body back at Hiccup, tail swaying in the air as he flashed his privates at the human. Moisture was already glistening on those folds, dark lips spread just a touch as the male's privates dropped from his slit. "So pick up where we left off, huh?" Toothless mimed Hiccup's question, eyes rolling. "Alright, I'm coming. I'm coming."

Hiccup approached the male and knelt behind his dragon. Resting a hand on Toothless's haunch, he leaned in to inhale the dragon's scent. He breathed out a soft moan as the scent swirled around his head and invaded his senses. Reaching a hand down, he stroked his already stiff member as he spread those lips just a touch. The dragon's body was burning hot against his fingers and getting even warmer as Hiccup's fingers stroked those silky smooth scales. Leaning in, he breathed in the dragon's scent as those folds pulsed with need. Between the sight and the scent, Hiccup's eyes began to droop as he felt himself drifting into a daze. Toothless breathed out a growl that was equal parts need and annoyance as those hips worked back. "Yeah, just a sec..." he droned in a dazed state.

He wasn't even aware that his body was moving until the tail pressed against his side. Toothless's hips dropped a bit as his legs stepped apart, bringing himself in line. Hiccup blinked slowly, starting to wake up as he pressed the tip of his cock against those folds. There wasn't a fiber in his being that didn't want this to happen. Arching his back, Hiccup looked down his body to watch as he spread the dragon open slowly. Toothless twisted his body around and watched as well, breathing out a pleased purr as the Viking sank his mace into those inner walls. Those burning hot folds clenched around his cock, pulling him deeper and deeper into the heart of the dragon's heat. Hiccup breathed out a moan as his body pressed tight against the dragon's body. Even with his cock buried up to the root, he was trying to press himself deeper into the larger creature. Hiccup let his hand slide down and idly traced a finger around the dragon's pucker. "If this is your tailhole, what am I buried in?" came the droned question, eyes lidded.

A little growl and a buck made him slid out of the dragon. He muttered something to the dragon and pushed forward, body smacking against the upturned rear. Toothless squirmed and wiggled back against him before rocking away and driving back. It was obvious what the dragon wanted to happen now, and Hiccup wasn't going to argue. Any thoughts of investigating or exploring were driven from his mind. That warmth spread out across his lap as his body drove deep into the male. A moan was met with a warbling purr as the dragon coaxed his partner to move faster, drive harder.

In a way, it felt much like flying. Two bodies moving as one. Toothless would wiggle and push back against him. Hiccup would tighten his grip and slam in deep, body smacking against midnight black scales. Arching his back, he let his eyes roll back with a moan as he hammered against the hide backside. Toothless's scent invaded his nose, driving his body to react on an instinctive level. Fingers kneaded and pulled on those toned haunches, feeling the muscles flex with each buck. Juices soaked his groin and dripped down his balls and thighs as the dragon warbled with pleasure. The insides clenched and pulled, drawing him deeper. Sweat ran down his body as he groaned, balls churning and aching. Hiccup clenched his teeth and groaned, leaning over the dragon as he hammered his partner hard and fast. Both were panting as their climaxes built and swirled around each other.

Caught up in the action as he was, Hiccup missed the glistening black scales that were starting to form on his groin. Anywhere the dragon's burning juices touched his body, the scales started to appear. They were heaviest around the base of his member, spreading faster the more the dragon leaked on his body.

Hiccup gritted his teeth and let out a growling noise, holding back the sounds. Living in such a tight-knit community had instilled a need for silence when seeking pleasure. Much like the other villagers, Toothless had no such qualms about making a racket. Head was rolling as the dragon called and cried out, letting anyone within range know of his pleasure. Fingers scratch against ebony scales as the Viking shook. He was barely moving now, the newly grown scales on his crotch smacking against the dragon's hide as his cock twitched. Hiccup was snorting and growling now, eyes locked on Toothless's back as his nails began to grow longer. Pupils began to twitch before growing a bit more dragon-like as he breathed out a snarl. Body slammed against the drake's as he let out a noise that was equal parts Viking yell and dragon roar. Driving his form against Toothless, he emptied his balls into his partner. The sleek form arched and pushed back against him, tail curling around his body to keep the Viking trapped against him. Toothless's insides flared unbelievably hot as juices squirted around his cock, soaking his lap as his seed splashed onto the grass.

Arms shook as fingers slipped against smooth scales. Toothless twisted to look back with a smirk, head angled with a curious purr. His tail flicked away as hips drove back, bumping the human. Without the tail to support him, Hiccup was knocked onto his ass. "Ha ha, very funny. Get what you wanted and now you just knock me over." He lay there on the soft grass for a moment, oblivious to the scales that continued to creep along his body. A purr came from the dragon as he twisted around, licking at his privates. As his tongue bathed over that seeded slit, the lips began to tighten and close up. Sharp eyes glanced over at Hiccup, ear lifting a touch as he watched the Viking's privates start to retreat. He gave a curious purr and twisted to sit on his haunches, watching as the scales spread further and the privates began to change.

"Not yet, Toothless. Give me a few minutes then we can play around some more." came the tired excuse. Hiccup yawned and scratched at his itching belly. Fingers picked at a scale on his belly, expecting that it was just one of his partner's that had gotten glued to his body during the sex. He plucked at it and winced as it pulled his skin. "Stuck pretty good there," he mumbled to himself as he sat up and looked down his body. "Are you shedding, Toothless? I mean, I know you got antsy last time you shed, but this is quite a lot of scales." It took him longer than it should have to realize that the scales didn't belong to the dragon. As he watched, the ebony scales spread across his thighs, popping painlessly out of his skin. He blinked stupidly at this development as muscles began to ripple under the scales. "What the..." he sat up to rub his leg. The touch invited a spasm as he got the worst leg cramp in his life.

Hiccup cried out as muscles clenched hard, scales exploding from his skin. They washed over his leg faster now, flowing across his skin like water over a rock. Muscles shook and tensed in their wake, thickening and pulling at bone. Joints and bone cracked under the shifting muscle. The affair was painless, body tingling as if it had gone to sleep. Toothless leaned in to sniff at the scales as the human dropped to his back and arched with a cry. The dragon circled worriedly as the human curled up and jerked, body expanding with each spasm. It was a matter of seconds before every inch of his body was covered in the ebony scales Ribs pushed against scrawny chest as his body grew. Bones pushed against skin before new muscle rolled over them. Hiccup rolled onto his hands and knees, spine arching to an almost impossible angle as a pair of wings snapped out of his flesh. He groaned, gritting teeth as a tail popped out of his spine, snapping at the air. Leather bindings snapped, his leg dropping to the grass as his body reshaped to a larger form. Cheek bones cracked and snapped as his face broadened and hair retreated.

Mere minutes after he noticed it, Hiccup lay in a heap on the grass. Mouth hung open as he breathed out a huff, head rolling slowly. Pins and needles erupted across his body before fading. He let out a groan and shifted, sleek body sliding over the grass. He cracked an eye open and looked down his alien-yet-familiar body. Alien in the sense that it wasn't the body that he was used to having, but familiar in that he had spent nearly every day with Toothless over the last several years.

"What happened to you?"

Hiccup licked his lips, "I'm not sure what..." Head swung around to look at the dragon. "Toothless, did you just talk?"

The nightfury tilted his head, "Of course I did. I talk all the time, not my fault if you're not smart enough to understand me." Feet shifted as the dragon moved in closer to sniff at Hiccup's body. "So what happened to you? Is it a Viking thing? Is that why the same-house male and females look so alike?"

A shiver raced down Hiccup's spine at the feel of that hot breath puffing against his neck. "W-what no. They look alike because they're Vikings, we all tend to be a bit big and hairy, for the most part." Head arched and rolled as the nose bumped into his neck and took a deep whiff. "Is this a dragon thing?"

Shoulders heaved in a shrug, "Not that I know of. Never heard anything about this happening before." The dragon nosed along Hiccup's body, examining and sniffing. Arching his neck, the Viking turned dragon sniffed at Toothless's form as well. With a new body came new, enhanced sense. His new nose was picking up all kinds of new layers to the dragon's familiar scent.

Hiccup breathed out a soft huff as he rose up onto his feet, balancing on three legs as Toothless slid against him. The dragon pressed his against Hiccup's, helping to support him as they sniffed at each other. "I mean, you're not a typical dragon. Last of the nightfury as far as we know. How many times have you been with another dragon?"

Toothless breathed out a huff, ears laying back. "Messed around a couple times, but never really been with one. Just some licking and stuff. Mounted a couple, but never been mounted until now."

Ears laid back as a warmth spread through Hiccup's body. "Well, makes me feel honored then. You know you were my first. Well, first to go all the way I mean."

"Yeah, I know. Hadn't really smelled any females or males on you over the last few seasons." Ears lifted curiously. "Speaking of which..." the dragon purred as he nudged Hiccup's tail with his snout.

Hiccup's body flushed hotter, "Toothless don't you think we should be figuring out what happened before you... Ohhh..." his voice rolled with a purr as the tongue brushed over his privates. Hips arched and pushed back as the tongue rolled against his body and slipped over his slit. Without even thinking, Hiccup's head drooped to return the favor. Nosing up under Toothless's thigh, he sniffed at the dragon's cock before licking across the firm length. Toothless breathed out a purr and ran his tongue from Hiccup's belly up across his folds then into those sweet lips. The Viking-turned-dragon moaned and swept his tongue along the dragon's cock then down to his balls and sweeping behind it to nudge at his folds. The slit behind his cock was tightly closed, and even a cursory probe found that the dragon's pussy was not where it should be. Hiccup twisted his head and licked further, tongue easing up to tease the dragon's pucker. "Where's that other hole? I'm pretty sure that I didn't imagine it."

Toothless let out a trill, "I think I know exactly where it went." His cock throbbed in front of Hiccup's nose as he licked again, lips vibrating against the new dragon.

"What do you mean? Body parts just don't move around without warning." The nightfury grinned as he twisted quickly, predatory form pushing Hiccup's tail up and to the side. A surprised noise came from the newly made dragon as his head twisted around. "Toot-toothless what do you mean you know where it went?" There was a nervous, yet eager, flutter in his belly as he feared and anticipated the dragon's answer. Foreclaws hook against his thighs as the nightfury pushed his tail further to the side. Hiccup dropped to his knees, looking back at Toothless.

The nightfury drove forward, cock pushing against Hiccup's backside. Sleek body rolled slowly as the dragon purred and ground against Hiccup's backside. "What I mean is that part of my body is now on your body." The feel of Toothless's cock grinding against his body, the ridged underside of his member sliding against the fresh nightfury. Head tilted playfully as the dragon grinned, teeth sliding out a bit. "Let's see if we can put the parts back together."

"Wait, Toothless! Don't you think we should figure out what happened before we do anything?" There was that flutter in his belly again as Hiccup looked back at his friend, watching that red cock grinding against his backside.

A purr washed over him as the nightfury reared back until the pointed tip of his cock was nudging against those folds. "I am gonna figure this out, the same way you figured out a saddle. Try many things until something works." Claws scraped against scaled hide as the nightfury drove himself forward. Both dragons let out a roar as the cock speared open the tight, hot pussy. Hiccup's head swam as Toothless's body smacked into his upturned rear. Wings flared out and beat at the ground as Hiccup's form rolled back into the male's. Toothless slipped down to press his chest into his partner's back as he groaned. "Feels like a female all the way in." His tongue rolled against Hiccup's neck as he breathed out a moan, easing his hips back. Both dragons trembled as the ridges popped and sent ripples of pleasure through their bodies.

Hiccup panted and pawed at the ground slowly, "To-t--toothless don't you think we should stop?" Even as the question was asked, the Viking knew the answer.

Tongue brushed against Hiccup's neck before the dragon gently nipped at it. "No. I'm a male nightfury, and apparently you're a female. If this lasts a day, a week, or forever, I know just what I want to do with you, partner." That heat flushed through Hiccup's body as Toothless said that. Lifting a leg, the nightfury half twisted and looked back. Sure enough, as Toothless had stated, everything down there looked like he was now a female. There was no penis evident, just a pussy that was stretched wide by the eager male. As she looked, the male drew back and gave a hard thrust, heavy balls smacking into the stretched twat. A purr came from the male as he wiggled and gave another thrust, driving a moan from the new female.

With each thrust, any thoughts of the village and his life back there began to fade. Hiccup rolled her form, twisting and sliding back against Toothless as she breathed out a growling moan. The ridges that spanned the underside of his cock was driving her wild. Evidently, Toothless had picked up a few tricks in the few times he'd messed around with another dragon. He seemed to know just how to push and where to grind to make Hiccup's insides churn and tunnel clench. Jaws clamed onto her neck, teeth scratching her scales. Toothless rolled and pushed, scratching at her body with his claws as well. Each scrape, every scratch sent tremors racing through her body. Her gut clenched and hips drove back against his body as she warbled out a pleased noise. Hot breath washed over her body as she arched and pushed, tail curling around the male's and squeezing it as her head swam.

Body shoved against his as she cried out, head rolling as she roared to the heavens. Blue flame rolled from her jaws as she came hard, hide trembling. Juices squirted around the male's cock as he hammered her body with his. Pushing deep, Toothless hammered against her body quickly. His knot rolled against her inner lips, growing rapidly. It was only a matter of seconds before it was stuck inside of her, locking the pair together. He groaned around her neck, fire rolling down her flank as his body smacked hers quickly. Hiccup's body bucked and pushed as the male's cock grew against her insides, stretching her virgin tunnel. The pointed tip of his member pressed against a final barrier deep in her body. Hiccup let out a hiss as a sharp pinch raced through her belly as the tip pushed through. Her hiss quickly built into another roar as she squirted around his cock. Toothless threw his head back and roared with her. The two nightfuries unleashed a twin blast of fire as Toothless began to unload into her. Burning hot cum filled her insides as the fire blasts exploded overhead. Hiccup shook under the male as he filled her with that liquid fire.

Legs trembled for a moment before she dropped to the ground with a huff. Toothless followed her down, the male laying his weight on her back with a rolling purr. Head nudged into her cheek and rubbed it as he covered her with his warmth. Warm inside and out, soft grass under and partner covering her above, she felt her eyes start to drift. A purr rolled up her throat as the male nuzzled her neck and covered her wings with his. Twined so close together, the pair drifted into a nap to recover from their tiring morning.

Hiccup's eyes fluttered as he woke up slowly. What fish had he gotten into last night? He'd had the oddest of night fantasies, dreaming that he'd been changed into a female nightfury and that he and Toothless had sex. Maybe he should lay off Gobber's special spiced smoke fish for a while. At least before bed.

Jaws stretched wide in a yawn as he blinked against the sun that glimmered off ebony scales. Hiccup's eyes crossed slowly to look at the wide muzzle that stretched out before his eyes. Hiccup blinked slowly before turning around to look down his body. Yep. Definitely a dragon's body. A purr vibrated against his back, making him glance over his shoulder. Toothless was snuggled up behind him, a half-smile plastered on the nightfury's features. Very slowly, Hiccup rolled and looked down his sleek form. Lifting the partial leg, he blinked at the sight of a still partially swollen slit, creamy white seed leaking from between the dark lips. Seeing it prompted an ache from her lower parts, a reminder of the mating she'd received earlier. Embarrassed fire flared along Hiccup's body as it all sank in finally.

So, it wasn't some dream brought on by highly spiced fish. Well, that was some good news at least, he liked the fish.

Rolling her body slowly, she slipped out from under the male's wing. Toothless shifted on the ground, pawing at the grass for a moment before rolling onto his back with a snort. Letting him lay there for a moment, Hiccup slipped towards the pools that were nearby. Within a few steps, she adapted to being able to move on all fours... well threes, adopting a quick loping gait. Stretching her body out, she began to run and then spreading her wings, started to take low gliding jumps. Heart jumped and raced as she felt her wings billow and catch the air, lifting her sleek body and send her sailing across the ground. Digging her claws into the ground, she picked up speed and took another jump. Wings snapped out, tail fan flaring as she hummed across the smooth grass. Legs stretched out, feeling the grass tickling against her palms before she dropped to the ground again.

She was so caught up in the joy of gliding that she nearly missed the springs. Digging all three heels into the ground, she skipped and skidded, stopping just before the edge of one of the pools. Hiccup stood there for a moment as she caught her breath. Looking down her frame, she fanned and fluttered her wings, watching them with a sense of wonder as a giddy tremor raced down her body. Licking her lips, she twisted this way and that to look along her body, examining it curiously. Advancing on the pool, she peered down into the water and looked at her own features. Her eyes were still the cool blue that they always were, instead of the intense green that Toothless had. Twisting this way and that, she looked over her new body and compared it to the other dragon. At first glance, the bodies were nearly identical. If almost anyone saw him right now, they'd think that she was Toothless. At least until they noticed the tail and legs. However, Hiccup had spent nearly every day for the last several years with his dragon. She knew ever last scale on the dragon's body, especially after the last few days. There were a few subtle differences in their bodies. An extra curve there, bit less muscle there, scales had a bit more of matte finish to them and were a touch finer in places.

"Having fun looking at yourself?" Hiccup twisted around, spotting Toothless on top of a rock. The dragon gave a sideways grin, "I'm definitely enjoying you twisting and turning around like that."

Hiccup huffed and turned around, planting her rear on the cool grass as her tail curled around her body. "I swear, you move as quietly as a shadow when you want." The male puffed out his chest and purred. "And as quiet as a hoard of drunk Vikings the rest of the time." He frowned at her and snorted.

Toothless oozed off the rock, "As if you're any more silent, always thumping around with your metal foot." He moved in and looked over Hiccup's body before leaning in to rub his head against her cheek. The rasp of his scales against hers sent a shiver through her body. Head arched with a purr as he nosed into her neck before giving a soft nip, teeth rasping tenderly against her form. "You gonna stand around all day, or slide into the pools for a soak?"

Leaning against his muzzle, she twisted to look at the steaming pool. "I dunno, last time I tried that I was aching for days from the heat."

A low purr rattled from the male as he worked his way down her form, "Yeah, but you were all soft and pink then. Dragons are a fair bit tougher."

Her eyes narrowed at the feel of his body scraping against hers. "Yeah, still not too sure about diving right in just yet." She leaned into the male as he circled around her body smoothly. "I mean, still kinda getting used to this whole thing of being a dragon, however long it lasts." A surge of fear rolled up from her gut. How long would she stay a dragon? A day, a week, longer?

Before she could think about it too long, Toothless ducked away from her. Without his presence there to brace against, she staggered and stumbled before falling into the pool. Hiccup had been thrown into water often enough that she knew not to panic. She braced herself against the expected rush of cold, so the gentle warmth that started to soak into her caught her off guard. A tingle followed on the heels of the warmth as she started to float in the water. Either there was something about the warmth or the minerals in the spring that set off some reaction in her body. The tingling spread to the very tips of her limbs before focusing in on her privates. It exploded outwards, sparkling along her scales, before racing inwards again. Focus and explode, concentrate and expand, over and over. She arched in the water, bubbles streaming from her mouth as she gasped.

Toothless swept in from the murk, his form pressing against hers. She could feel his purr roll through her body as his limbs brushed against hers, intensifying the thrumming. She arched and twined against his touch, inviting and reciprocating as well. Claws stroked over bodies, exploring one another. Wings batted against water and each other as they twisted through the water. Tails brushed over one another, fans spreading and stirring up the water. They sank through the water until they touched the bottom of the pool. Hiccup's body was pressed into soft sand, hot water bubbling up around her dragon form and rippling across her back. Even this far down, in the darkness of the water, she could make out the shape of her partner, his outline almost glowing with a bluish light. Toothless arched proudly over her, head angling to press against her maw. Lips locked together as he blew air into her mouth, sharing what he had. Hiccup arched and rolled against him, rubbing her belly scales into her partner's as she shared his breath, spent air bubbling out of their lips.

Legs slid against his thighs as her tail wrapped around his, lifting her haunches off the sandy bed. Toothless moved with her, hardness gliding across her ready lips before sinking into her depths. Cheeks flushed hot with embarrassment as Hiccup gladly pushed against the male, taking him into her depths. The water both encumbered and enhanced their motions. It forced them to slow down, adding a new grace to their motions. Her body sang as he fulfilled a need that had been whispering at the back of her mind ever since she woke up. Insides trembled and pulled at the male, coaxing him to dive deeper into her form. Toothless responded to the silent command, pressing his slit flush against hers. He throbbed inside of her tightness, her heat combining with the spring water to make the male surged inside of her depths. She broke the kiss, a stream of bubbles carrying her moan up towards the surface as her body throbbed under and around his. Toothless pushed against her, pressing her down into the sand. Instinct drove Hiccup to wrap her limbs around the male, holding tight as he pushed off. Wings beat against the water as his knot beat against her inner walls. Sinuous bodies pushes and rolled as their wings pumped. She could feel him just barely sliding in and out of her tightness, lips stretching and pulling against his knot. It pulled at her, swelling quickly and catching hold even as they started to soar upwards through the water. He pushed deeper and deeper with each beat of their body. Faster and higher rose their pleasure as they neared the shining surface. The nightfury pair broke through the surface with a gasp, Toothless pushing his tip past the female's cervix. Twin bolts of blue flame burst from their maws as they roared at the heavens. Her insides rolled against him as he erupted into her deepest chamber. They rose as one into the air, wings still beating. He twisted as they started to come down, taking the hit as they landed beside the pool. She breathed out a huff and lay on top of him, head swimming as she felt him filling her up.

Toothless breathed out a purr and lay on the ground, his eyes drifting closed as his paws idly stroked along her flanks. Hiccup rolled her head against his neck, "Going to sleep again."

"Yep."

"You know, I've heard plenty of fights between Vikings because the guy just goes asleep after sex."

"I've heard too, but I'm not a Viking."

Hiccup kneaded at his chest, sitting up just a little. She bared her teeth, "Maybe I should start a fight with you then."

Toothless heaved over, pinning Hiccup between him and the ground. "Or I could just lay here till you calm down."

She squirmed under the slightly larger male, "Cheater!" Despite her protests, she was purring as their muzzles touched, the dragons nuzzling each other tenderly.

Astrid was grooming Stormfly when the call came out. "Hiccup's back!" She sat upright and smiled at the mention of the other dragon rider. She felt a surge of joy as she saw the familiar shape of Toothless swoop into the stables. The smile was replaced with a frown as she stomped towards the dragon and rider.

"And where have you two been for the last month?" She growled, storming towards Hiccup as he dismounted. Stormfly stomped behind her, squawking at Toothless even as Astrid yelled at his rider.

Hiccup winced and turned with his typical ashamed half-smile. "You won't believe what happened." Toothless looked over at the rider with a smirk before nudging him with a shoulder. Hiccup shot his dragon a look and rubbed his head. "Well, you see. Toothless and I were out flying when he happened across a... uh... a female Nightfury. And then... well..." Astrid followed his gaze to the stable entrance. Six baby nightfury dragons came tumbling in, squawking and pouncing each other even as they came in. "Surprise."
