"Fu, what the hell are you doing?"

"Relax, kid. It's standard procedure."

"And since when were you a doctor?" Jake huffed as a pair of paws were pressed against his chest, rubbing in small circles.

"Gotta make sure you're in peak condition," Fu-Dog justified, tracing the pads of his paws over the smooth scales.

"So what is this? A check up?"

Fu smirked as his paws trailed lower. "You could call it that..."

Jake sat on the edge of his bed while Fu was feeling him over. The canine burst into his room spouting something about checking him over. When Jake asked why it was so important Fu said something about adult dragons going through some kind of change.

The dragon went along with it at first but as the shar pei traced his claws along his scale covered abs, Jake started to suspect that it was total bogus. Well, at the very least it did feel good...

"Be real with me, dog. You're making this stuff, aren't you?"

That smirk he gave earlier returned to Fu's muzzle. "Maybe. Maybe not."

The dragon's eyes widened and a shudder ran through his legs. He could feel the dog's paws pressing and tracing along his cock. It didn't take much to coax it into hardening but it was obvious that Fu was pressing and dragging his digits in specific places.

"Aah... H-hold on- W-whoa!"

A digit was pressed against and popped into the warm fold of his foreskin. A deep chuckle came from Fu as he felt around. He curled his digit, gently dragging it against the extending cock within. More noises came from the dragon as he started to fidget, experiencing something foreign invading the thick scaled skin covering his cock. Adding to that was the repeated rubbing of his semi-hard. He never felt anything like it before.

As his cock started to fill with blood it grew thicker, adding pressure to the digit that swirled around his cocktip, sending a sharp bolt through his loins.

"See? Just let ol' Fu look you over..." The space became too tight for him so Fu pulled his digit from the moist space, watching it pop free. His nostrils flared and he looked at his paw. Upon a closer look the dog could see his single digit wet with a mix of sweat, cum, and other fluids. Bringing it closer to his own face, Fu couldn't help but sniff at the stuff. As the scent set in his nose, the canine's eyes drooped and a growl of satisfaction rose from his throat.

He continued to sniff, his mouth watering against the dragon's slit musk. He could easily tell it had been a while since the scaly creature washed himself. Fu pulled his paw away and sniffed at the air, being aware of Jake's musk made it easy to sniff it out along his body. Some parts of him were muskier than others and the dog's nose was leading him to one of those places.

Jake's cock steadily grew harder until it stuck out on its own, already filled with blood and lightly twitching. But to the dragon's own confusion, it was left untouched. Foo's nose continued to twitch, stronger than before. It picked up something even stronger, drawing him in like a mouse to cheese.

And cheese had a similar scent. Foo was on his knees, flicking his tongue across his muzzle at the sight of the dragon's large, scaly feet. They hovered just above the floor, the toes wiggling a bit. The sight entranced the gray dog, making his mouth water even more.

Jake just stood there on the bed but he could feel the light air of the sniffing dog against his clawed toes. His foot reeled back as a reflex, exposing the wide sole. Those toes spread apart, the stink between them wafting out more of the slightly cheesy smell.

"Damn, kid. Have you always smelt this good?" Fu asked, reaching out to grab the moist foot. It was soft against his paw pads, the thin layer of sweat wetting his own paws.

He leaned in close to the foot, shamelessly pressing his nose against the wide, smooth sole. A loud snort came as his nose dragged upwards towards the toes. Now the sounds coming from him were deep purrs of excitement. Just a few sniffs already had him trembling and nearly drooling on himself.

A strange tingling raced up Jake's legs, brought on by Fu's nose pressing and sliding up and down his feet. He couldn't help but curl his toes against the cold, wet thing. But that seemed to only fuel Fu's huffing. Now there was something warm dripping down his sole. The feeling wasn't bad, but the dragon certainly wasn't familiar with such a feeling.

Another strange sensation came, making the dragon shudder. This time it was strong, even making his cock pulse. He was struck with something warm and soft dragging up his foot. Then it happened again, leaving his foot wetter than it was before. The dragon finally looked down to see Fu swiping his flat tongue against his sole, all the way up until he reached the toes.

"Fu, ugh... You know I've haven't cleaned them..."

"You're talkin' to a dog here, kid." Fu chuckled and resumed his worship of the large foot.

He used his other paw to reel the other foot in close, sandwiching his face in between them both. Letting his lust drive his actions, the gray hound proceeded to grip a foot in each paw, huffing and licking them both, swiping his tongue across them both. His nose raced between the two of them as well, huffing the thick odor of sweat and foot funk.

His tongue sailed upwards, lapping up the bitter tang of dragon sweat. The dog couldn't get enough of it and he went straight for the dragon's toes, flicking his tongue in between them. A deep shudder ran through him at the deep, biting flavor. It clung to his tongue and the reek between them was strongest. Drool dripping down his chin and deep moans slipping from his muzzle, Fu pressed his lips against the flexing toes, flicking his tongue back and forth between them.

Fu's nose twitched as he picked up a new scent. It was even stronger than the dragon's feet. Letting his body lead him to the source, Fu trailed back up Jake's body, loud snorts coming from him as he neared the origin of the smell.

"H-hey, Fu! Ease up..." The wet nose sniffing along his body made him feel weird, even more so when Fu would press the cold thing against his scales.

Fu ignored his words and pinpointed what he was looking for. "Oh boy, I am glad you skipped out on a shower..."

Jake was about to ask what the dog was talking about but he jumped at an ice cold nose lodged deep into his pit. He could hear the loud snorts coming from Fu as he huffed the dragon's pits. Just a single whiff of the pungent stink nearly made him melt. The dragon groaned again, not only from the wet nose against his pit but from the thick spurts of warm precum that flew from Fu's cock.

There was no end to the stuff, as the dog grew hornier, more of the hot, sticky jetted from his cock. After splattering against his scales, the clear fluid oozed downwards, spreading the sensation further.

A part of Jake was completely weirded out but an equal part of him was excited by it all. He himself had taken a few whiffs of other guys but Fu was taking it to a whole new level. Coming to contrast the cold nose was the hound's hot tongue, swiping against the sweaty cleft.

As soon as his tongue touched the muggy space a sour taste spread and gripped his taste buds. But the canine loved it, only wanting more as he smacked his lips. A tingle ran through Jake's arm, brought on by another slow drag of Fu tongue. Huffing, moaning, and spraying precum, Fu continued to bury himself into the reeking space, all but losing himself in the scent alone. Even after being scrubbed by his tongue, the dragon's musk remained strong and acrid.

It was like a drug to the hound, even as his nose was pressed as far as possible, Fu only wanted more of it. Sweat dripped down on his muzzle, making it wet along the thick oozes of drool that dripped from the corners of his mouth. In nearly every sense the canine was a gross mess. The fur of his face reeked of foot and pit stink, other parts of his pelt were matted with his own drool and precum that splattered on his own body when he moved.

"You sure are a weird dog," Jake huffed, finally caving and letting the hound do what he wanted. At this point it was too late to turn back and he was hoping that he could get something out of the dog's actions. His cock was still hard, throbbing and leaking from the tip. But the licks and sniffs from Fu were way too distracting to focus on it.

"You don't even know the half of it," Fu chuckled, drawing his soiled tongue over his muzzle. "Got a good, healthy stink going on, kid."

"Uh, thanks, I guess."

"Dragon funk like this doesn't come easy," Fu chuckled. "You got a gift."

"Some gift..." Jake muttered to himself.

"Hey, I know a couple of creatures that would kill to get a whiff of ya!"

Fu pulled himself from Jake's armpit, taking a final whiff of the smelly space. His cock gave a stronger pulse than usual, spraying another load of precum across Jake's abs.

"Ugh..." Jake grimaced but there was nothing he could do about it.

"W-whoa..!"

Fu got between Jake's legs and heaved the dragon over. Getting the idea, Jake rolled over, getting on his hands and knees.

"I really hope you know what you're doing," Jake whined, his cock now starting to hurt.

Fu could see the long, thick cock pulsing hard and he smirked. The veins along the fat foreskin were bulging, pumping extra blood into the now rock solid length.

The dog licked his lips and leaned in close. He wasted no time sniffing before he pressed his nose against the hot, scaly sack. He could hear the dragon gasp and the orbs bounced against his nose. Sweat dripped from the ballsack and soaked into the fur along his face.

Deep snuffs exposed Fu to a spicier brand of the dragon's musk. He hummed again, drawing his tongue over the smooth balls. Another gasp came from Jake, this time one of pleasure. Just the simple lick of the dog's hot, soft tongue sent a quiver through his loins.

Jake's cock jumped on it's own and gushed a thick line of precum that splattered on the bed. Fu saw this and gave a toothy grin, another deep chuckle leaving him.

"Aaauuh!"

Jake's whole body shook as he Fu slurped up his balls, swishing them within his mouth. His tongue spread his hot savila along the scaly surface, spreading that hot, wet sensation.

Hearing the dragon's squeals of pleasure made Fu's heart leap. He didn't expect such a sound from the larger creature. A series of hard suckles came as Fu lapped and slurped at the heavy orbs, licking up the sweat and light grime that added a tangy taste.

"Mmmrrph..!"

Fu wiggled his tongue faster, tracing it along the smooth scales. He changed the intensity of his actions. One moment he was lightly tracing the tip of his tongue against the musky heft, the next the canine was roughly dragging it back and forth, raking his taste buds against the smooth scales.

While Fu's mouth was filled, his eyes trailed upwards, falling on the large, winking rim just above. The rhythmic clenches of the pucker were almost hypnotizing. As he continued to worship the dragon's balls, Fu couldn't help but wonder what it smelled like, what it tasted like.

Fu gave another suck to Jake's balls before leaning back, locking his lips around them. He continued to pull himself back, his ears filled with the dragon's grunts and hisses. Finally, the spit-slathered balls popped from the dog's mouth, flinging strings against his muzzle, only adding to the dampness of his fur.

"Get a load of this."

Jake's eyes widened and a tremble ran through him. Right underneath his tail, the dragon could feel a pair of soft paws on his backside. They were already brushing against the soft scales, nearing that soft, puffy hole at the center. Just the thought of it already had the dragon trembling in both panic and anticipation.

Fu's nose led him closer to the large rim. His paws were already upon it, his digits pressing against the soft skin that lay beyond the scales. As soon as he did, the scaled beast groaned, a long and breathy sound. Fu was absolutely loving it; the sights and the sounds were riling him up. His lust was full blown, even stronger than what Fu thought possible. Between his own legs, there was a puddle of precum, soaking through the blankets and into the mattress lying underneath.

"Hmm, it's kinda loose, kid. You haven't been foolin' around behind my back have you?"

Jake could feel his face heating up, memories of the day before replaying within his mind...

Fu continued to test around the area, indeed finding that Jake's hole was much looser than usual. It gave him an idea but he quickly brushed it off in favor of the twitching that struck his nose. Like a bee to a flower, Fu was drawn in by the powerful coming from the dragon's tailhole.

Before he even knew it, the shar pei's nose was already pressed against the puckering hole. It was wide enough for his nose to slip past the rim just a bit. His knees suddenly were weak and a sudden lightheadedness struck him just off the first inhale of the nearly suffocating stink of dragon ass.

Pressing himself in even further, Fu's entire muzzle was now pressing past the soft ring. Deep whiffs were taken within the hot tunnel, making Fu's head spin and his cock freely gushing pre like a broken faucet. Jake's ass clenched down on his muzzle, smearing his nose, pelt, and lips in the dragon's anal fluids. Now the reek of Jake's ass was all his sense of smell could register.

A moan came from Fu and his tongue flicked from his mouth, dragging against the soft flesh within. Another clench came, followed by a deep groan from Jake. Fu licked again and it all happened again. His muzzle still buried in the dragon's ass, the dog smirked, realizing what the specific spot was. Fu licked at the spot again, this time making sure his tongue passed over the sensitive bump slowly.

Jake was panting heavily while his ass was steadily being stretched. He wasn't sure what Fu was putting inside of him but there was the deep sensation of being filled nonetheless. But soon after there was something else. Striking the red dragon out of nowhere was a sudden press to his prostate. His entire body shook and his cock seized, nearly being pushed over the edge from the simple lick. Just when Jake thought that was over and done with, there came another. The dragon grit his fangs but a moan still escaped through them. Another bolt of bliss soared through his shaft but Jake was fighting against it...

Then came that long, teasing lick Fu purposely laid down over the dragon's prostate. He knew full well what he was doing and he waited for the fireworks to happen. Sure enough, Jake's jaws parted as a long winded moan rose from his throat. His cock jerked between his legs, pulsing hard before spraying thick ropes of seed against the bed. Splatter after splatter of dragon spunk decorated the blankets, soaking into the fabric instantly.

While Jake was pushed over the edge, Fu endure the hard clenches of the dragon's strong anal muscles clamping down on his muzzle. As they came down on his face, the dog couldn't help but sniff when his nose touched hot flesh. His tongue also flicked against them, raking up the unfiltered taste.

Jake was left panting heavily as his orgasm tapered out. But the pleasure still traveled through him, forced along by Fu's licking and the pressing of his nose. The dragon was still trying to get a hold of himself but the steady licks and prods deep within made it nearly impossible.

Fu decided he wanted to move onto something else, as he removed his muzzle from Jake's ass he got the perfect idea. After all, the dragon just got his rocks off, why couldn't he? After popping his face free from the hot tunnel, he swiped his tongue over his nose and lips, lapping up the fluids secreted from the dragon's ass. While he did that, the dog rose from his knees and stood up to the perfect height.

Jake was glad to have even a second of let up from the intense feelings that were forced through him. But his breath caught in his throat as he felt one paw touch his tail before pushing it to the side while another paw gripped his toned asscheek, giving it a good squeeze.

"Try to hold still, kid.."

With no more words exchanged, Fu pressed his cock against the puffy hole, shivering as he rocked his hips. Already slick with precum that continued to spurt, Fu's cock ground against the smooth scales. Jake was moaning just from the small bursts of pleasure. He could feel the dog's cock hotdogging against his ass, smearing and dripping that hot, sticky stuff all over his backside. At the very least, Jake was glad he wouldn't have to worry about lube...

Having a good feel for what he was working with and unable to stand it anymore, Fu drew his hips back and aimed his cock before ramming himself inside. Moans came from the both of them but Jake's were particularly pitched as Fu gripped his hips and got busy shoving himself back and sight of the dragon. The stretched hole soon became sloppy thanks to the precum that still jetted from Fu's cock.

A series of wet thumps sounded as the chubby hound rutted the bigger magical creature. His cock was engulfed in wetness and a deep heat. It traveled up his cock, daring to make his knees weak again. But Fu powered through it, gritting his fangs and bashing his pelvis against the dragon's taint and balls.

"This is why I love dragons. Inside and out, they're nice and hot..."

His cock pulsed against those soft, hot walls forcing them to take his shaft. With each rock of his hips, the canine buried himself a little deeper than before, aiming to make the dragon's depths as loose as his rim. With nothing more than deep grunts and hefty breaths, Fu held tight to Jake's backside, picking up the pace of his pounding.

All that came from Jake were deep moans and the occasional hiss from being stretched deep within. Fu was far from the biggest male he had taken but the canine was hitting all the right spots. It made sense, if anyone knew how to pleasure a dragon it would be Fu-Dog. His previously spent cock was now painfully hard yet again. Each pump of the dog's shaft sent tingles from his ass straight to is dick, making it pulse and start to leak.

Fu grunted and gave an extra hard press of his hips. Following it came a squelch and the thump of his hips crashing against the dragon's ass. Jake cried out again, his ass stretching around the knot forced within him. He clenched his fangs and blew smoke from his nose as a sharp tug pulled the bundle of flesh from his pucker.

Wrapping an arm around Jake's tail, Fu let out a low moan as he thrust himself even faster, now shoving his entire cock inside before forcing his knot and shaft from the hugging hole. Aside from the moans coming from the magical creatures, the room was filled with the thud of fur crashing against scales and the sloppy 'pop' of a thick knot being pushed and pulled out of a loose, sloppy hole.

"Get ready, kid. Mmph... Just a bit more..."

The rutting canine slowed his pace drastically. He pushed himself in as deep as he could before drawing back and forcing his knot from the clenching tailhole. These motions were repeated over as the canine focused on giving that final push before he came...

That final push came in the form of Fu clenching his eyes and giving a long howl the moment he shoved his knot in again. But the canine continued to push himself inside, forcing his shaft and hard knot even deeper within the dragon's ass. That was all he could manage before every inch of his throbbed at once. Like his abundant supply of precum, Fu's balls churned and pulled up, forcing his real load from the furred orbs and up the shaft.

Finally, Fu shot his hot load. The first spurt fired a large wad of seed into the dragon's guts. Another deep pulse of his cock fired a second rush of thick seed that rushed from his cock all at once. With his eyes screwed shut and his mouth hanging open, all Fu could was pant as lighting bolts struck his entire being. A first rush of cum came, followed by a forth.

Jake was groaning just like before despite Fu not humping into him anymore. Instead he could feel something hot and wet spurting inside of him. But it was followed by more and more and more... He could feel the shar pei's dick pulsing deep inside of his ass and every one of those pulses sprayed more hot dog spunk inside of him. In between the throbbing of his cock, Fu was cumming more than some much larger dragons Jake managed to take...

Even after the tenth pulse, Fu's cock didn't stop. His balls were magic and thanks to his level of lust, there was a lot backed up that rushed for an exit.

Cum began to leak heavily from Jake's ass and the dragon was starting to hiss more than he was moaning. Taking the other male into consideration, Fu pulled back and forced his spraying cock from the dragon's ass. Not a second later did more volleys come, jetting from the tip with great force. Gripping his shaft and giving it quick tugs, Fu whimpered and panted, forcing the rest of his load out at once.

As he humped into his own paw, Fu's cock let loose thick streams of hot, sticky cum that splattered directly on Jake's ass, quickly glazing his toned asscheeks in layers of pearlescent dog splooge. Some of it arched high before coming down to streak across the dragon's back. After a few more seconds the hound finally relaxed as the jets were soon nothing more than thin dribbles. Fu lifted his gaze and chuckled at the product of his work. Jake's lower half was absolutely slathered in his spunk and the room itself reeked of virile dog cum. Despite blowing the biggest load that Jake had even seen, the dragon could feel a pair of paws through the heavy, sticky stuff clinging to his scales.

"Y-you're not done yet?!" Jake asked. Between the stuff sloshing within his ass and the stickiness that wouldn't leave him, the dragon wasn't sure if he wanted a repeat.

But Fu had yet another idea of what he wanted to do. Between the pounding he gave Jake and the many loads that were sure to slick his insides up...

Without saying anything more, the chubby dog pressed both paws against Jake's ass. After they slipped inside, Fu pulled them in opposite directions, stretching the messy hole. After taking another good look he nodded and decided to just go for it.

He slipped his left paw in first, letting it sink inside of the hot, wet hole. Jake was at a loss for words. It was certainly bigger than the dog's cock. As soon as it was inside, Fu slicked his paw back and forth, giving a bit more stretching before he pulled it back. His entire arm was matted with his own cum. Perfect.

"You're gonna love this, kid. Hehe. Haven't done this in a long time..."

Jake was about to ask what Fu was referring to but another deep filling of his ass made his mind go blank.

Fu grunted as he slipped his left foot past the stretched rim. As soon as he did his leg was being pulled in by the greedy hole. With a smirk on his muzzle, Fu heaved himself up, clinging to Jake's tail before lifting and forcing his right foot and leg inside of the dragon. Fu let Jake's body do the rest as he let go of the tail and steadily sunk more and more of himself past the expanded pucker.

"Aackk! Y-yeah! D-damn, dog... Good thing you're so thick..."

That was the last thing Fu heard before his head slipped inside. All around him were hot fleshy walls made slippery by quarts of his own seed. It already clung to his pelt, making him just as slick. He slipped lower down the dragon's ass, the space becoming tighter around him.

Reverting back to his old ways, Fu took deep whiffs at the space. His cock flared to life instantly at the mixed ripe scents of dragon ass, dog cum, and their own sweat. As his nose bounced, Fu's paws traced along the soft walls until he found what he was looking for.

"Auugh! Y-yep that's definitely a whole ass dog inside of me. What the hell is Fu doing in there..?"

A gasp parted Jake's maw. Fu's paws pressing and dragging against his walls left him balling his fists and arching his back.

"F-fuck... He's in so deep..."

The rubbing got even faster coming from two different places within him. As he continued to moan, drool leaked from the corners of the draconian's mouth.

"That should be enough 'foreplay' for now," Fu chuckled. He gave a final press and rub of Jake's prostate before slithering a bit further. He grunted as cock slid over the hard bump. It had been so long since he had done something like this.

"Mmm, been a while I've had something to hump..."

Grinding his cock against the slicked, hot flesh Fu's hips rolled back and forth. Deep pants and moans slipped from his muzzle, a product of that tingling that raced up his cock. Not only did his dick drag against the flesh but so did his sensitive balls. Every stroke struck the whole of his loins at once and Fu was left wanting more.

"Haah! F-ffuuuck..! Grrk..."

Jake dug his claws into the fabric, tearing into them. He still wasn't sure what Fu was doing but his ass was filled and there came several bolts of intense shocks. It was clear the dog found his prostate and was going to town on it.

"Damn it, Fu... Rrrk! I can't... S-shiiit!!"

Jake's cock started to spasm all on it's own before more ropes of his cum joined the puddle underneath him. A few strong pulses shot gushes of his spunk against the wall. They landed in loud splatters before oozing downwards.

"O-okay... H-he's still going..! Alright..."

While Fu was still humping against the large mound, there was a rocking of Jake's ass. The walls around him were soon squeezing down on him in a steady rhythm. Sticky ropes were forced against his pelt, leaving a thick layer of his own cum further soaking him.

"Knew he wouldn't last long," Fu chuckled and rose out the squeezed and the sloshing of cum against his own body.

As soon as the pressure around him eased, Fu laid himself flat against Jake's prostate, laying his head flat against the smooth flesh. His hips bounced up and down, slicking his cock against the dragon's anal walls. His motions made his balls slap against the sloppy surface, the sound dulled out by the squelches and gooey pops.

Even faster than before, Fu ground his cock back and forth, pressing his shaft between the slippery anal wall and his own cum covered fur. He continued these motions until his eyes bulged and his muzzle hung open. As his tongue snaked out, drips of drool falling from it.

A shiver ran up his spine, he snarled and then barked. Sharp pleasure finally built up to that frenzied peak. With his eyes rolling and his paw dragging against the wet walls, Fu's cock unloaded heavy rope after rope. The stuff spurt from underneath him, spraying his own stomach and chest. He could feel the heat and stickiness already bleeding through his fur but he smiled against the sensation.

As soon as the bliss within tapered out, Fu growled again and rocked his hips once more. While he humped, his paws slicked over the anal walls, pressing back and forth in time with his own fervent ruts. With his hips plowing his cock against Jake's ass, and his paws rubbing the dragon's walls, Fu added to the experience by sniffing at the closed off, rank air. He moaned as he acted as dirty and shameless as he could, the thrill of being a filthy mutt coming back to him for the first time in nearly a century.

Faster than he expected, the hound's cock swelled and fired off more heavy floods of his cum. It filled the space around him, quickly pooling higher and higher. The canine had to lift his head to above the pool of cum that was now Jake's ass. Against his own motions, the hot, thick bath was nice and warm, the perfect sensation to end off blowing three loads.

"Mmm... Think I'm gonna stay here a little while..." Fu leaned against the sticky lining of Jake's ass and sighed as he enjoyed the soft flesh and the warm cum that gave him nothing but comfort.
