A Visit To the Doctor 2 - Another Visit - by Amethystine

A much different sequel to this old old, tiny tiny tale: http://www.furaffinity.net/view/361505/

---

A dragon of the anthropomorphic variety sat in one of the waiting room's over-sized armchairs for the doctor's plus-sized patients. The chairs were for anyone who was of a large species, or just over-weight. The massive male was of average build for his species, strong and maybe a tiny bit stout, but certainly not fat. He had a full head of horns consisting of two large ones that swept smoothly back over his skull and two smaller ones more to the sides of his face. Directly below said smaller horns were small indentations in his smooth scaly skin that marked the locations of his ears, the dragon having no external auditory equipment save for the slight rise of his skin around the aforementioned holes.

The chair he sat in was a rather wide and plush piece of furniture, as wide as a love seat with a much deeper distance to the backrest. There were other ones just like it at each corner of the reasonably roomy waiting room, nestled at the junctures between the rows of drab and conjoined seats for normal-sized people. There were also piles of cushions for tauric or serpentine creatures. There weren't any taurs in the room, but the dragon glanced from the mounds of pillows to the merged multi-seating occupied by the random assortment of avians, mammals and smaller reptiles, and swallowed heavily. A troubling thought had clearly been brought to his mind by his surroundings.

He cautiously lifted a hand to rub against one side of his patterned neck, scratching slightly along the base of the finned ridge that rested there. Along the middle of his pointed muzzle were a series of thin, fin-like spikes. The rigid reptilian ridge wrapped around his head to follow his spine down over his neck before they both disappeared into his shirt. At the same time, they sunk into his back, clearly shrinking down into his scales to terminate between his shoulder-blades. Another thing that vanished into his t-shirt was the series of stripes that marked his neck and back, whose lengthy horizontal range reached around him just enough to be seen as sharp, dark points on both sides of his throat from the front.

He looked rather anxious. Waiting rooms had that effect on people, and the large reptile seemed to be no different. Sitting there in his baggy blue pants and sandy coloured XXXL shirt, he also nervously held a red blanket around himself, shrouding much of his shape. It seemed to be the comforter from a king sized bed, and with the expression on his dull-green scaled snout and the way he clung to the cocooning cloth, he looked like a much younger version of himself, like a hatchling holding a security blanket, even his soft spade-tipped tail was tightly wound around himself and the blanket. Black bands ran across the length of the tail's back, the points of said dark patches wrapping around its girth, like the ones on his neck.

Every once in a while, he would shift and shiver, holding the cover closer, as if feeling cold in the agreeable air of the doctor's office. Each time that happened, he would also begin to take deep, calming breaths, his taloned toes tightening tensely against the tan carpet of the room while he shut his eyes and tried to think of other things; mundane, boring things.. anything to stop himself from losing control.

To the other onlookers in the office, he was obviously off-kilter about something.

Before long, an attendant announced his name and he quickly shuffled towards the back hallway that led to the examination rooms.. and blissful privacy. On his way there, a magazine tumbled out from under the thick shawl that was the comforter. The dragon hadn't been reading it, and heaven knows no one would want to steal the ancient assortment of articles, so the flopped open copy of 'Snake's Digest' was a mystery to the reptilian receptionist who saw it fall and subsequently replaced it onto one of the waiting room's tables. Her sensitive scaly snout wrinkled at the musky smell that wafted from its pages, making her mutter something about men.

Meanwhile, the draconic man in question had made it to the cramped examination room. Ducking his head to enter, he shuddered more fiercly at the chill he experienced as he settled in to wait for the doctor to appear. He snorted at a small stool that sat in the back of the room against a blank wall before moving said stool aside to slump down against the wall, his wide and tall frame filling the free space. He curled his tail around from where it sat wedged against the wall behind his butt, placing the black diamond-striped appendage in the lap created by his digitgrade legs. He may have been anthro and wingless, but he was still pretty big. He idly thought about how his full-blooded ancestors or the few true dragons left in the world would never have been able to fit into the room he now occupied.

The grey-green guy glanced at the always oddly disconcerting charts of various species' internal anatomy, then groaned and shut his eyes, trying not to picture what his body must have looked like on the inside at that point, pulling the cover more tightly around himself.

After a shorter wait that managed to feel even longer than the previous one.. thanks to the thought that once he had left the _waiting_ room, the _waiting_ would be over, as well as the claustrophobic nature of the cloistering closet of an examination room he was squeezed into and sequestered in.. the doctor finally arrived.

Walking in, the feathered physician frowned in the midst of his customary question of "Well, what seems to be the problem..." trailing off as he saw who was waiting for him, "... Mattheis?" The crow looked down at his clipboard and back up at the dragon, frowning due to the discrepancy in who and what he thought he was entering to examine. "I'm sorry, there must have been some sort of mix up on my most recent receptionist's part, and I may have to go find the proper patient."

The dragon shook his head, "No, you're in the right place!" he insisted, resisting the urge to moan.

"But, you're not Mattheis Nye. Nye is a naga who I saw when he first found he had Furrison's disease. I mean, Sudden Transformation Syndrome. Of course, that was before _everyone_ got it, but I digress.. 'Nye' is the name that's next on the list, not your's."

As the aging avian was about to go, another voice appeared, announcing: "Ssso, that'sss why she didn't asssk you any annoying quessstionsss when you gave her my name." The sibilant sound seeped from the blanket, and as the doctor turned around to confirm what he had heard, a golden orange and dark purple serpent slithered out from under the large layer of concealing comforter. He flicked his tongue as the dragon who had been hiding him shivered strongly, still clinging to the quilt. "Heya Doctor Etz."

The black bird was bewildered, boggling at the two boys. He couldn't fathom why Mattheis would bother to sneak his snaky self into see him. He looked as healthy as could be.. well, what he could see of him, anyway. Peering at the pair, Dr. Etz could only see a small portion of the python poking from the dragon's disguising clothes and the cocooning crimson comforter. Stepping closer, he wondered where the rest of him was hidden, as there did not seem to be enough room under the larger reptile's loose-fitting outfit.

"What's going on here, you two? Were you trying to both see me at the same time to avoid both waiting.. or maybe it's something about your friend's health insurance?" he asked the snake, standing before them both, eye to unblinking eye with the serpent who was somewhat standing in the dragon's lap, thick body resting on the ground in the midst of the drake's massive, strong legs. As the doctor looked at the snake, who was the same size as he was, he idly pondered the dragon, who dwarfed them both, being roughly double the size of the two standard-sized species.

The snake's shape was framed by the full draconic body behind him as he hissed and hesitated.. before a firm push from behind made him wobble in place. He looked surprised and swallowed noticeably before spinning around to mutter, "Sssettle down, Eiam! Before you make a messs of thisss place.." Even with the draconic one sitting, the standing serpent barely had to bend while berating his big buddy. Even then, the seated scaly's slouch left his snout lower than it would have been with proper posture. The slender horned head only nodded and held his peace as the brightly coloured constrictor turned back to address the doctor.

Swallowing again and taking a deep breath, the constrictor confessed: "Uh, doc.. me and thisss dragon were kind of fooling around, and we got.. ssstuck."

After some seconds of silence, the snake saw that the doctor did not quite comprehend their conundrum, so he quietly coaxed his companion into concluding their covert cautiousness. Carefully standing up, Eiam pulled the blanket free, revealing that one of Mattheis' thick coils was looped around his waist, apparently protecting their privates. The snake seemed to be fully supported by the standing scaly, and also appeared to be much less lengthy than an adult-sized serpent should have been.

The dragon turned away from the doctor, peeled off his partially pulled up pants (Mattheis' mass made it so the leg coverings could not have been pulled all the way up, thanks to how the snake had wound around Eiam's midsection like a bulbous belt) and shucked off his shirt while the notably nude naga unraveled from him to stand at the doctor's side. The dragon's dense body, bared to the bird, was a sight to see.. small smooth scales made up his thick hide, so fine that it nearly looked like flesh, from a distance. Despite possessing a petite paunch, the large male's muscles visibly flexed over his form as he stretched and shuddered in the cool air of the examination room. Anyone who was watching would have been able to see why the snake had been sweet on that certain scaly.

Speaking of the snake, though he stood next to the doctor, his lengthy form went directly from where he rested to the dragon's unseen front, as though the tall anthro creature was holding the serpentine tail to his belly. Eiam began to turn around, his somewhat long neck was angled down to fit his head under the ceiling, the small ridge that aligned with his spine just barely brushed the beige ceiling tiles.

As the area that the medical professional was supposed to examine was finally facing forwards, any sort of expectation the crow had was completely destroyed. The dragon's member was not 'stuck' inside the serpent's slit, nor was it anywhere to be seen. Furthermore, the snake's body wasn't bunched up into some tight knot upon the wingless drake's groin. At first glance, the area seemed perfectly healthy and empty of evidence that would suggest recent ill-advised, illicit interludes.

But upon looking closer, the physician saw that the snake's thick form seemed to sink directly into the dragon's body.. into the dragon's widely stretched genital slit, to be exact. If that had been the extent of the observable symptoms, and if it was not obvious to any onlookers that it was more than just a small amount of the serpent's tail end that was missing from the picture, one might think that the plucky pair had simply become stuck during some scaly-centric sexual experimentation. But there were several things that caused the crow some considerable consternation.

First of all, the doctor had noticed how the naga's scales suddenly stopped a few inches under his chest, the belly beyond being bare flesh. The bright colours of the constrictor continued onto the skin, causing his casual glances to have glossed over the glaringly abundant absence of scales. The yellow underbelly, which would have normally been lined by wide slithering scutes, instead had a thick bulge that took up half of the wide band of creamy colour. The meaty mound ran straight down along his length, like a thick tube had partially emerged from the bottom of his body, making a long lump in the sleek skin. Other random ridges ran over the rest of his sides and back, here and there. They wound and curled over his surface for rather short distances, occasionally branching into two lines, almost like vines.. or roots, due to how they only surfaced somewhat, as if the majority of the meandering maze of mysterious mounds were under his skin.

Gradually, the good doctor's gaze was guided to the serpent's snout. The naga was nearby, allowing the avian to see something seeping slowly from the small slot in the lamia's lips. It was the space in the scaled snout from which its two-tined tongue could slip out to flicker in the air, but at that moment, there was some slimy substance beginning to bead on the tight opening. Obviously thick and sticky enough to amass in such a way, it could not have been drool.. the snake licked it up and swallowed it back down before too long, still surreptitiously trying to hide the full extent of his condition.

The naga's bulged belly only barely touched the ground between his apparent 'base' at the dragon's waist and where his upper self stood, yet the supple skin that sat there on the cool tile floor caused both subjects to shiver slightly. It was clear to the crow that both foolhardy parties could perceive the unpleasant sensation as if it was upon their own flesh.

And if all that had offset the older one that quickly, you can imagine how concerned the couple had become in the interim time! They stood there together, the dragon moaning quietly, his hands unable to keep off of the thick protrusion that extended from his groin.. while said protrusion, the snake, stood in front of the doctor with a pleading look in his lidless eyes, silently hoping that an explanation was forthcoming.

After remaining silent for so long, just staring at the strange set of symptoms, the doctor blinked once, and seemed to come alive again, saying, "Oh, I see. Well, boys.. I'm sorry to tell you this.. but this is a rare condition that can occur when a snake, serpent, snakeman, snakewoman, lamia, naga or Yuan-ti engages in sexual activity with a somewhat larger reptiloid species. Usually dragons, drakes, wyverns or a significantly larger lizard species that has a semi-magickal heritage. Basically, the snake..." he paused, nodding to the young python as he went on, ".. becomes integrated.. fused, if you will, to the reproductive organ of the dragon." He then nodded to the large dragon lad before continuing once more, "The serpent's body, through a fluke of genetic compatibility and ancestral anatomy affected by arcane accidents, slowly replaces the dragon's genitalia."

It was then the tangled two's turn to be bewildered; blank, blanched looks locked onto the long-winded little crow.

"In simplest terms.. you are turning into his penis," explained Etz. "It's called Serpenitalia. I'm very sorry. There is no cure.. partly because in the most basic biological sense, both your bodies don't see anything wrong with the new configuration."

Finally breaking free from the lengthy stares both scaled beings had been burrowing into Etz's black feathered hide with, both peered at each other and their shared body, slowly coming to terms with the totality of their tanglement. While they had held onto hope that they would be separated --somehow-- before they left the doctor's office, they now had to face the fact that they were forever fused.

Attempting to hurry along to the good news that followed the bad he had just delivered, the doctor went on: "But, the afflicted are known to have very long and very, very, _very_ happy lives, despite their odd pre-dick-ament.." he coughed and cleared his throat, "..excuse me: I mean, despite their strange situation."

Pausing for a moment to ensure his unintentional pun hadn't been a major gaff, the crow continued, trying to explain the exact nature of 'naga nethers', as the condition had been called, colloquially. "In fact, with a dragon's storied longevity, your lifespan will almost certainly be considerably lengthened," he said to the surprised snake. "While your _organ_ is lengthened," he mentioned to the massive reptile, glancing to the dragon, his eyes trailing directly from the serpent's snout to Eiam's groin before jumping up to his equally dumbstruck visage.

"Whoa, whoa, whoa.. my lifessspan will be lengthened? What're you talking about, doc?! My life isss pretty much over now, isssn't it?"

"Well, I suppose.. socially, you won't be able to--"

"No! Ssscrew my sssoical life, I mean I'm going to actually die! Aren't I? I'm going to turn into a ssslab of mindlesss meat hanging from Eiam'sss waissst!"

"My shaft was internal, actually, so.. you wouldn't be hanging so much, I think..." Eiam's interruption trailed off as he was withered under a sudden searing stare from the snake. Never before had anyone been so scared of their own sex.

Turning back to Dr. Etz, Mattheis made his worries known: "Yeah, whatever! I'm still going to turn into nothing but a big, ssstupid, lifelesss cock! All becaussse thisss bassstard trapped me in hisss goddamn vent! How long do I have until I lossse my armsss.. until I lossse my voice, my eyesss.. my brain..?" Beginning as a wrathful round of rather rhetorical questions, by the end of his raging rant, the reptile had been reduced to a quivering collection of coils, cuddling against his 'captor's' crotch, cradled in Eiam's arms. Perhaps the python's conjoinment connection caused him to turn to his 'host' for support, through a biological bonding.. or maybe Mattheis really did care for the dragon, despite his diatribe.

Struck dumb by his patient's impatience, the good doctor spoke up when Matt settled down, soothingly saying: "No, no.. that doesn't happen, not completely! The snakes who develop Serpenitalia don't fully transform into a simple sex organ!" The python perked at that point, peering up at the medical professional as he pressed on, "In fact, they retain their intelligence entirely, as well as their upper bodies. I think the only thing you stand to lose at the moment is a bit more of your length.. or size. That is, you might end up a bit smaller."

"Oh thank fuck," gasped Matt, endlessly relieved.

"Yeah.." muttered Eiam, also visibly less tense. "And did you hear? You won't be so hard to carry around, either!" As soon as the dragon had said those words, it looked like he regretted it, realizing any of his inconveniences were trumped by the serpent's worry over his continued existence.

Mattheis' head snapped around to glare at the green-scaled guy from who's groin he grew. But instead of delivering his destructive payload of his piercing python peering, his snout softened and he actually smiled at Eiam, the weight that had been lifted from his shoulders allowing him to see the humour of the drake's little lingual slip-up.

Smiling meekly in return, the larger of the fused fellows reached out to lightly rub the base of his shaft.. or the lowest of the naga's coils, depending on how one looked at it. The tender touch made them both relax a little more before the doctor spoke up once again.

Having busied himself with retrieving a rather large volume of a medical text, the crow had let the pair absorb the information he had given them about one body absorbing the other. After getting the book out, he had flipped to the entry dealing with their condition and showed it to them as he spoke.

"As you can see, by the end of the merging process, the snake involved takes on a few phallic features and shrinks to a size that makes them proportionate to their new host, but remains rather reptilian. Retaining, as I said, their normal appearance in the upper body. Except the teeth." Dr. Etz's black taloned fingers drew the eyes of his two patients over the handful of pages, pointing out illustrated diagrams of how their bodies would wind up and photos of exemplars of others afflicted with the odd occurrence. All in all, the actual photos showed pairings of people that seemed rather nonchalant or even content with their condition. There were even a few females.. which could have possibly been herms.. that Eiam seemed drawn to, causing Mattheis' body to stir.

While the serpent questioned the doctor about the issue of his dental situation that the avian had glossed over.. and while the bird explained how the snake would end up with no teeth at all by the time the metamorphosis had come to a finish, Eiam examined the large book further.

When he had a chance to interject, the dragon did not comment on the interesting gender issue of Serpenitalia, rather saying, "They seem bigger than proportional, Doc.." in a tone that at once sounded both happy and like he was trying to hide said giddiness at gaining girth over his previous penis.

"Well, it does seem like it's more along the lines of the serpent remaining as large as possible while still being small enough to be easily carried by the draconic half of the fusion.. as well as being able to erect properly and.. I suppose still at least somehow achieve, umm.. relations with a female of the dragon's species," commented the crow, carefully walking the line between medical professional and vicarious voyeurism.

Eiam was grinning ear to ear at this point, both amused at how the physician was fidgeting around the facts and the facts themselves: He was going to have the biggest feasible snakecock he could possibly have. Perhaps his elation was infectious, seeping into his serpentine body-mate, or maybe his friend-turned-phallus was also finding the avian's attempts at a proper and professional bedside manner to be comedic, as the snakeshaft was also snickering somewhat.

Turning from the large tome of medicinal knowledge to gaze upon the green dragon and his purple, yellow and orange python partner, the doctor assessed them anew, which quelled their tittering. "Now.." he hesitantly began, appearing unsure on how to proceed. One got the impression that while he had heard of the condition before, he had never needed to deal with it. Nevertheless, he pressed on, saying, "..I'll need to make sure there are no complications from the conjoinment process. As I said, your bodies act as though this is a natural occurrence, due to ages-old alignments of your anatomies.. but like something natural, such as, say.. pregnancy and birth, we want to make sure they're proceeding as they ought to."

The merged males nodded, murmuring their understanding and consent.. until they suddenly stopped upon hearing what the bird was getting at.

"So, I'll need a.. umm, a sperm sample."

"What, really?!" both boys blurted, in unison.

"Yeeeeup, 'fraid so," shrugged the crow, side-stepping toward the door, around the astonished dragon and his ever-so-slowly transforming serpentine friend. "I'll just leave you two alone for a bit so you can.. well, come to terms, I guess."

After Etz had left, Mattheis turned to look up at Eiam, "He seemed pretty casual about that request, don't you think?" he said, still balking at the idea of it, unable to imagine becoming intimate in such a sterile setting.

"Oh, I don't know," Eiam half whispered, slowly starting to stroke the sinuous sides of the snake, where it emerged from his pelvis. "I'm pretty casual about masturbation when I'm alone.." he quipped, grinning. Not really giving the naga the chance to respond, save for the soft hiss that had been building with the caressing to the cock-like coils, the dragon continued: "Not to mention the fact that whenever you move.. and especially when you talk.. mmm.. it feels so good to me."

Remembering how the dragon had seduced him in times past, the python felt the similar tone and volume of the rumbling baritone taking him back to happier, more horny occasions. "Me ssspeaking.. It feelsss nice, doesss it?"

Nodding emphatically, yet slowly enough to retain his cool, calm composure, the drake rumbled deeply enough to let his shaft shiver with the vibration of it. "Mmmm, yeeesss! And when you hiss like that, it's wooonnnderful," Eiam announced, elongating his words in tandem with long, tender strokes along his manhood, inching up Mattheis' body, heading for the still-scaled upper body that sat atop the partly penile python. To the dragon, with every second that passed, his nervous system knitted ever closer with the sensations of the snake's skin, sending more and more marvelous messages to his mind from the massage their merging masses were receiving.

For his part, Mattheis immediately began a low, constant hiss.. he could imagine how it could feel to have one's own organ orating, the tip somehow making itself tingle with a soft, blissful buzz. He grinned and half-slithered, half-curled his body up on itself, drawing himself back toward his delightful, bodily 'host', wrapping what was left of his length around the large body to which he was anchored. The serpent coiled around the thick torso, snuggling down against the black diamonds of Eiam's back and sides before playfully and purposefully pulling his partially penile form around against the thick dragonhide, slithering flat on the full flesh of his friend, his sensitive scales grinding over the slightly rougher skin, hissing louder than before.

A low groan poured out of the bipedal recipient of those heaven sent feelings, his form practically quaking with the intense rumble that accompanies the wordless, inarticulate utterance. The snake was working around his side, and he was barely able to stop himself from grabbing at the source of his supremely sexual sensations. Eiam did manage to hold off until Mattheis stopped himself, snuggling himself securely against the dragon's chest, his thick, rather turgid tube of a form having been tautly drawn around the more robust reptilian shape.

Mattheis muttered something about how he realized that he wouldn't be able to wind around his big teddy dragon any more, if he was going to shrink further, toward a more member-like size, so he needed to do it one last time, then and there. Eiam nodded in silence as he cradled the constrictor's upper body against his front. Their forms pulsed in unison, their arousal being shared, their heartbeats syncing up, as unbeknownst to them, the dragon's mighty heart finally fully took over for the snake's. After a moment of contemplation, Eiam quietly pointed out that, despite the naga's inability to coil around him, they would at least never be apart, never be alone.

To be together forever, the thought struck them both as incredibly romantic, despite how they might have reacted in the past to such a suggestion. One might suspect that some biological imperative led to a more harmonious integration, their linked biology gingerly influencing their thoughts on the matter. Others have surmised that, deep down, those who end up being afflicted with Serpenitalia are actually cosmically destined to be together forever anyway, and their bodies simply reacted to the will of the world. Still others eschew such spirituality and sentiment for a more subtle subconscious solution, saying that, deep down, 'sufferers' of Serpenitalia find the idea of being joined together in such a sex-centric manner to be rapturous, that the only people that the 'illness' can affect are those who would have wanted to merge, had they hit upon the idea themselves.

Regardless of the reasons or rationale of their rather rousing relationship, the reptiles were reaping the rewards of their intimate intertwining. Eiam cuddled and caressed the coils that were curled around him, which Mattheis was actively moving against the dragon, dragging the soft, smooth skin over the scales. The snake had also taken to nuzzling his nose against his companion's broad chest, between the vague shape of the larger male's pectorals. Eiam moaned softly, hands exploring and gently massaging the lowest line of scales on the serpentine shaft's form, just below the python's chest, fascinated at the fusion, the transition from the sleek plates to the tender skin of his cock. Of course, the scales were also very much a part of his maleness.. a maleness that felt like it was rubbing its own tip against his front.. which it was, honestly.

Hissing as he slid his snout against the dragon's sternum, Matt moaned somewhat himself, his entire length alight with intense lustful intent. His form felt like it had been emptied of everything, save for sexual sensations.. which was more true than he knew at that moment. His internal organs had been subsumed by the spreading structure of Eiam's extended dragonhood, his biological needs met by the host organism. Blood from the dragon's heart and air from his lungs, as well as food from his belly, when hunger would strike. No longer needing to breathe would allow the naga to delve into tight spaces where oxygen would be hard to come by, after all. He was sure to breathe and talk and consume things in the future, though.. if only to jumpstart their shared arousal time and again.

The slowly transforming snake held around Eiam's torso, delighting both himself and his friend with agile movements of his fingers, flexing them and fondling the dragon's flesh in general. Even if the dragon had been trying to contextualize the feeling of Matt's hands with something similar in his fornicative history, he could not have. He wasn't trying, too busy brushing the thick, throbbing form of his phallic friend, but if he had attempted to describe it, he might have likened it to giving a normal shaft highly sensitive whiskers that twitched and touched tenderly and sweetly, teasing and tantalizing the rest of the cock with their nimble scouting, as if warming up the main meat for the excitement to come.

And then those fun little portions of his penis decided to dance over their own glans, his pole pleasuring itself as Mattheis massaged over his own smooth snout, making them both gasp, the snake hugging around himself as the dragon drew his dick into a deep embrace.

The sexual serpent could still gasp and moan and hiss and groan (and speak, when not so aroused as to be incoherent) because of one small sac that was left from the takeover of his innards, which could move air in and out of the constrictor-cock, and over his vocal chords. It was that which let him continue to correspond with his conjoined comrade, although their communication was bound to go beyond words once their bodies had blended so.

The pair's innate understanding of one another was fortunate, as Mattheis felt his form filling with something other than just ever-higher levels of pulsating pleasure, something that soon reached his throat and would have made talking impossible.. and even made his moans muddled. In the midst of running the sides of his wedge-shaped snout back and forth across Eiam's chest with occasional pauses to nuzzle the front of his face more firmly to his bodymate's front, his steady hissing became a soft sputtering, and the slow dragging of his head suddenly switched to a slippery thrust across the dragon's ribs.

"Ooh!" cried the draconic one, gripping Matt all the more firmly as more of that foreign filling feeling flowed into the phallus' face. They discovered that the snakeshaft was drooling a lubricating liquid which had helped his head to glide over the green scales.. it was Eiam's pre-cum. At first, the dragon felt a bit embarrassed to be causing his compatriot to cough up the clear pre-cursor to their pleasurable peak, but he was swiftly assured by the silenced serpent's obvious enthusiasm for his erotic evolution, going back to sliding his head against Eiam's front, smearing more and more of the slime onto the smooth expanse to expand his exciting activity to being able to easily slither his whole upper body against his host's, filling them both to brimming with bewitching bliss.

That happy accident turned tawdry was all the duo needed to delve further past foreplay and into actual action aimed at acquiring the sample their doctor had asked for. Eiam's hands grasped around Matt's back and added to the addictive gliding, pressing the snakecock's body to his more firmly than the serpent could manage on his own. Despite being still able to flex and curl his coils, Mattheis had found that his body had been becoming more and more stiff with their continued caressing. By the time the gradual metamorphosis had finished with the couple, the reptilian rod would be forced into an immobile state when erect, bobbing with Eiam's racing pulse, the back of the naga's upper body brushing against the dragon's chest. But for that first time together, the snake could still spiral loosely around his linked lover while their lusts loomed ever-larger.

Leaking loads of pre, the python licked at the dragon's pectorals.. moreso to stimulate his own tongue than to massage the muscles. Eiam gasped, feeling a more intense version of what he had experienced with Mattheis' fingers running over him.. suddenly, there was a super-sensitive spike of pure silky sex gliding around, extending from the end of his member. It was almost too touchy.. too tender to taint with tough, hard scales. Eiam scooped the end of his sexy snakeshaft up into his arms, pulling him up to swiftly kiss the head and tuck the ultra-delicate and flickering forks into his maw.

With the extremely erotic embrace, an eruption of ecstasy exploded from the kiss. Eiam was unable to control the rolling of his hips as he hugged the huge erection that was his mate, mashing his mouth against that of the maleness.

Meanwhile, Mattheis moaned muffledly into the large lips upon his snout. Something in the back of his mind made him want to plunge deeply into the tight, wet space he could sense between and beyond the smooching lines of scales that suckled on his tongue. He realized what that instinct was and found it amusing, choosing to resist it until a later date. Continuing to undulate his sinuous length against the dragon's body, which was quickly heating up, he felt how his entire being thrummed with a heavenly hum, continuous pleasure pouring into the base of his body from the dragon of which he was fast becoming a part.

Their connection was perfectly reciprocal, as Eiam felt as though the flow of flawless pleasure was all coming from his heavy, hyper-sized cocksnake. He kept kissing, continuing to milk massive amounts of mind-melting joy from Mattheis' tongue, sucking on it, wrapping it with his own large, tapered one. Never able to maintain a hold between the virtually frictionless fluid-flush flesh, it didn't stop them from trying to twist the dexterous lengths together tightly enough to extend the brief moments when the two slippery serpentine muscles were threading through loops of the other, for in those half seconds, their indivisible elation skyrocketed, over and over. With their inexorably linked libido launched, the partnered pair's gyrations grew all the more desperate.

A crushing need for climax claimed them both, the dragon's arms tightening around the serpent, who began to buck himself up through the slick ring his host had formed with his limbs and front.. the copious pre-cum that had never stopped issuing from Mattheis' mouth having been spread all over Eiam's torso and arms. The snake's own arms curled around the thick neck before him, their scales grinding against the dry shoulders of the drake as they repeatedly wrapped and unwrapped around the draconic neck, providing contrast to the gliding going on lower down. As his cock thrust itself up and down, Eiam and Mattheis continued to kiss, meeting as each of the snake's pumps reached its zenith.. their smooching slowly switching to sucking, tongues still entwining as much as they could. They moved in complete, consummate concert, the immaculate rhythm born of their gracefully enmeshed systems.

Mighty thumps had been thudding out of the dragon's tail as his melange of self-pleasure and love-making had ramped up, the strong, long, pointed limb twitching and shivering with Eiam's excess energy. A momentary flash of societal awareness zipped through the dragon's mind and he quickly drew his tail up and wound it around the throbbing base of his flexing phallus in an attempt to arrest the noise that might attract investigation. The tiny reminder about where he was and the illicit thrill of being caught in the act.. and in such an admittedly alien act.. only served to send another spike of sexiness into the many peaks of pleasure the pair was producing.

Eiam squeezed and pumped his tail over a long section of his serpentine organ, panting while Mattheis moaned murkily under the layer of goo that coated his urethra-throat.

Both of them could tell they were millimeters away from achieving an amazing apex, and they groaned together under the weight of their swelling orgasm, which loomed on the horizon, just out of reach.

In his needy state, Eiam recalled how a certain serpent would utilize his tailtip to probe the depths of the dragon's derriere, spurning him on to splendid coital conclusions. All in the same moment, Eiam realized that Mattheis would never do that again and that he himself must be the one to do so. He whipped his tail free from his lover-turned-cock to arch his own supple, spaded tailtip up between his legs and under its own base, plumbing his own pipes, prodding his prostrate with the tucked up tri-point tail, which both of the merged males felt in their very cores.

Immediately, Eiam let out a roar, which was almost instantly stifled by Mattheis shooting upward against and somewhat into the yawning chasm that was the dragon's mouth. The owner of the ophidian organ could feel a fabulous fizzing as his body tensed all over, every one of his other parts seeming to squeeze a spectral something toward their centre, toward his quivering crotch. While his host felt the beginnings of release, the naga's nerves were near nirvana after the sudden intrusion by a distant part of his own body seemed to take it upon itself to stimulate another much closer portion of his altered anatomy. As Eiam's form forced all its energy into the arousing addition it had recently acquired, the snake felt like he would soon explode with more than just the dragon's seed.

Swelling in those last seconds of supercharged sex, Mattheis felt his scales stretch softly around his upper body, feeling full of both the fluids and froth of fornication itself.. like the whole of the romp had been squeezed into his slender form all at once, and would soon be ejected from his head, which pounded in an impossibly pleasant manner, an inverted headache, where any twinge or shudder was a source of bliss, rather than the usual discomfort.

And then, they both felt the geyser of goo as it arrived, both sensing it in their own way. Eiam felt the rushing as an extremely exaggerated version of his typical tawdry termination, sweetening it tenfold or more. Mattheis was suffused with sexual fulfillment as well as literally filling with a flood of fluids as he forced his face just a bit further into the dragon's snout, poised to deposit his potent payload.

As one, they came.

The cock-naga's phallic body rippled with the force of the dam breaking and his coils directing the initial firehose-like spray of semen. It felt like a firehose to them both, in any case.

The dragon's body humped the air and his tail flexed under himself where he leaned his wingless back on a wall. His jerking movements did not actually alter his equipment's placement, but he could not stop himself from doing it, so powerful was their combined climax.

A gargantuan glob, formed from the first, freshest and most forceful of the couple's considerable reservoir was swallowed by Eiam, luxuriating briefly in an idle fantasy he had about cumming like that forever. Of course, he knew he (or rather, Mattheis) would soon slow and stop, and they would need to return to reality. The full weight of reality hit Eiam then, and he drew back his head in a lightning-fast maneuver that caused a stray spray of milky cum to shoot straight up, not only hitting the ceiling, but also causing the tile that the jet of jizz impacted to be knocked up and out of the thin metal frame that held it.

Letting out a soft 'eep' at the uncontained eruption, the drake glomped his snout back down on Mattheis' still mostly blissful, but slightly confused face. Eiam kept the rest of the raunchy launches in check as he hurried around the small office in a pleasurable panic until he found what he needed. He stood over a small sink in the tiny counter at the back of the examination room and rammed the plug into the drain, just in time to guide Mattheis' snout down toward the polished metal basin, letting the last of their now co-owned sperm spill out into the sink in slow sluices as he sighed and sat down heavily on the ground. His snakecock unwound from him as he flopped to the floor, remaining extended up over the steadily filling sink.

Finally able to speak again, Matt's first words were still a bit gurgly. "Do you think thisss is enough for the Doctor?" he laughed amid the very last, widely-spaced helpings of their heavy cream.

When Dr. Etz knocked gently on the door and then re-entered the room, he found his patients re-dressed and re-wrapped in the blanket that had brought them there. He smiled politely, and they did the same back.

"Had enough time to talk things over, eh boys?" he asked. "I'm sorry I took so long, I actually saw another quick patient for some general questions about medications. Anyway.." he trailed off and rummaged around in one of the deep pockets in his long white coat and produced a small, fist-sized jar, finishing his thought by asking, "..ready to give me that urine sample now?"

Matt and Eiam looked at one another slowly, then slowly turned back to look at the bird.

"Ummm.."

"Didn't you sssay that you needed, uhh.."

"Yeah, I'm pretty sure you said it was.. the other kind. You know.."

"Sssperm."

Looking surprised, the doctor chuckled, "Oh! No, not at all.. oh my, did I say sperm sample, before? I'm sorry. And sorry again for making you wait while I got the container for the urine sample. I did think you two would need to just talk about how you'd be proceeding, moving forward. I mean, one of you would probably move into the other's place. I daresay it'd make more sense to have you both living in the larger place, which is probably Eiam's, right?"

As he spoke, the crow peeled the lid off of the small jar, readying it for his patients. "Anyway, at least dragons urinate out of their cloacas and not from their genitalia, eh Mattheis? You wouldn't want to deal with that, I would think."

Still dumbstruck, the conjoined couple had been creeping toward the door, even while their doctor was constantly turning to face them. "Uh, doc, we need to go.. but let me ask you something.. can't you get all you need out of a sperm sample, as well?"

"I suppose so, but why, it's much easier to get a urine sample, right?" Etz curiously answered, holding the cup out to the two at the door.

"Uhh, you'll see," Matt muttered before excusing himself and his bodymate with, "We're going to go make a follow-up appointment, okaythanksbye!" Most of his last sentence was spoken as Eiam opened the door and bolted.

Dr. Etz just stood there, a little flabbergasted, for once. His hand still held out the empty jar.. which was suddenly over-filled by a huge dropping blob of off-white slime. The giant droplet, which both filled the cup _and_ splashed out over the bird's entire hand, had been dangling down from the dark void in the ceiling caused by the missing tile.

It was only then that the crow noticed the smell coming from the sink.

And now, for your viewing pleasure, here's a picture of the happy couple after their transformation has finally fully completed, leaving them at the end-stage of the "illness" that is Serpenitalia:
