Abducting Amethystine ~ By Amethystine, with consultation from Rhylith & Torri

---

Prologue

While the python had, at times, thought that he had a lot of knowledge to impart to others, he also never believed that he could become a teacher.

But, as he sat up on his slowly re-expanding coils, he knew that he needed to teach the twins in front of him a lesson that they would never, ever, forget.

~

Part 1

The twins in question weren't your conventional sort.. but of course, it wasn't a typical bit of teaching that the constrictor planned on laying out for the squirming siblings.

First of all, Rhylith and Torri were closer than most sets of twins. Much closer. They were so close, that they shared clothes, worked at the same job, shared meals.. even shared the same bed, and the same lovers. Although, all of those details were trifling when one considered that they shared a body.

Torri and Rhylith were two halves of a whole hydra, thrust together under mysterious circumstances.. made more mysterious and muddled by their tendency to teasingly tell tales of how they came to be hewn so inexorably together. Said stories could possibly ring true at times, or only in parts, but the pair's prolonged practise of informing their friends that the other's recountings were false further confused the issue.

No matter how they came to be the way they were, their appearance was simple enough to understand. People meeting the duo for the first time could easily tell one entity from the other, thanks to a convenient case of coincidental colour-coding. Rhylith, the male half of the apparent fraternal twins was a cool shade of blue, and had a mop of short almost sky blue hair atop his short-snouted head.

Torri, the female side of the set had longer locks of a deep crimson, which went exceedingly well with her half of their hydra-body, which was a slick scarlet over most of her side's flesh. Along the front of their body, Torri's red lightened to a pink, and Rhylith's naturally shifted to a shade of cyan, not unlike his hair.

Divided down the middle of a rather human-like bipedal body, they shared everything 50/50, including their arms, legs, and long sinuous tail.. even the heavy pair of two-toned tits, the single shaft and the feminine folds hidden under the aforementioned maleness. Each of the genders that made up the Gemini had brought something the resultant herm could enjoy.

Especially their cock.

The pair's purple pole was their pride and joy, the perpetual key to their pleasure, moreso than any other erogenous area on their sensitive form. Perhaps it had been something about the way they had wound up merged, they way their nerves had knitted into one another.. or maybe it was something about how Torri found it so endlessly erotic to possess the potent symbol of sex, the alien tool of malehood. And Rhylith.. well, Rhylith IS a male, after all. To him, all other aspects of their body are just distractions from that single all-important column.

So it was that while they did freely share the bliss of their bonded body, there was still never _quite_ enough to go around. They always, always wanted.. NEEDED more. Much more.

Pills. First for more intense encounters, then for growth. It wasn't enough, it didn't last.

Magic. Their attempts to cast spells on themselves were always foiled by their arousal diverting their focus.

Toys. Both mundane and magical, items that stimulated and enhanced, forcing fuller flesh or adding temporary turgid tallness, but it was all too fleeting for the phallus-fixated twins.

Before too long, they encountered the idea of snake-cocks. They heard it from a friend, for whom they feel forever in debt, due to what that revelation led them to. A serpent-shaft was the simple-seeming concept of either conjuring or conjoining a coily creature from or into one's own organ and enjoying the outcome: a living, lustful length of mobile maleness, sinuous and smooth, sleek and strong.. and supreme of all considerations for the hydra: Sinfully sizable.

Unfortunately, the notion may have been an easy one, but in practise, it proved problematic. The conjoined 'couple' couldn't conjure a complex corporeal creature, and physically securing the sort of serpent they dreamed of the old fashioned way was more difficult than they imagined. They still had orders waiting, nevertheless, but their desire was desperate, and while they attempted to alleviate their agonizing wait, they found a fitting folly to occupy themselves with. Something that might have been just as good.. a way to try out the very variety of kink they had blindly thrown themselves into.

In a local apothecary shop they knew from the supply-ordering portion of their own supernatural business ventures, they discovered a product that granted them a short-lived snake-cock experience. It was a type of single use alchemical-infused condom that transformed the wearer's manhood into a mamba. Well, the first box they bought were mambas, at least. They upgraded quickly from 'CondoMambas', to 'Rattlesnake Rib-Ticklers', to 'Cobra Crowners'.. all the way up to the flagship product of the line, the 'Anacondoms'. The twins were so tense and excited at the prospect of their transformation that they had scarcely slipped on the latex sheath and the loops of the magically manifesting serpent were brushing up against their inner thighs, that they came, ending the limited effects of the potion-laden rubbers.

They only worked until orgasm.. or for two hours. Rhylith and Torri never lasted past two minutes.

Irretrievably hooked on the hedonistic hemming of herpetology's hugest specimens into their sex, Torri had been enthusiastically bounding over to the shelf in the quaint little shop to grab a fresh box of Anacondoms when Rhylith gasped and caught his sister's red hand, exerting his control over the blue arm to force her to put the package-powering package back down before pointing silently across the store. He was indicating single figure, and Torri instantly understood when she saw what sort of creature her brother was showing her.

A naga.

And not just any naga, but a python. A gigantic, lengthy, thick, extensive, voluminous fellow. They both knew, deep in their shared heart, knowing with a certainty like the sun rising in the morning, with the strongest sense of their unspoken and instinctual hydra harmony, they knew that they had to have that snake.. down between their legs.

He was speaking to the sales clerk spider from whom the hydra had been buying their numerous boxes of metamorphic maleness-coverings, but in a voice that implied command and authority. This boa was the boss.

After the constrictor's departure, the large lamia having slunk off into the back room, confirming that, at the very least, he was employed by the store, the twins walked as calmly as they could to the counter and the chitinous clerk. Torri had tried to flirtatiously and furtively figure things out from the fidgeting arachnid fellow, until Rhylith tried the direct route, seeing his sister getting nowhere with the short, shy male. It was the serpent's shop, as Rhylith managed to learn from the bug. The name of _their_ naga was Amethystine, of 'Amethystine's Alchemical Apothecary', the boutique upon which they had stumbled, where they were then standing, from which they had been buying their boner-boas, short-lived though they may have been.

Undeniably, there was an urge coming from both of the two minds that controlled the conjoined form that was the hydra. An urge to march proudly into that employees only area and strip down before claiming their mighty coily cock. Luckily for them, while the notion was irrefutably there, they were actually able to suppress such suicidal schemes. Each of them kept themselves in line for the sake of the other, realizing concurrently that they'd have to be more cunning than brazen.

After the afternoon of their startling and groin-gripping realization, the twins returned the next night to nab their naga.

Breaking into the store was a simple matter, as was how they knew he was working late that night. Such trifling matters were beside the point and easily disregarded next to the pair's ultimate goal, which luckily had his back to the door when they peeked one of their heads inside.

Rhylith and Torri snuck up on Amethystine and leapt upon his long, serpentine lower body. They then cast a quick spell to fuse Amethystine to their body while he struggled to reach one of the potions in his lab coat, but his arms disappeared too quickly.

His long, thick tail was sucked into their body, his mass compressed, fused away to be used and abused by the body-snatching duo. Amethystine was shrunk down while being positioned in his new home: Rhylith & Torri's crotch.

Part 2

Ame had been turned into a serpentine sex organ. Their original cock had been moved and modified, crowding his suddenly toothless mouth as his new dexterous cock-tongue. Their magic made him into a manageable size of about 2 feet long, with their vagina acting as a sensual sheath he could retract into.. but only while they were flaccid, which they would rarely be, while they had their new powerful python of a pole.

While the twins had fantasized about owning the full-sized naga as an obedient slave to their sexual inclinations, they had come to terms with reality.. at least a little bit. They knew they'd have to break him in first, and then they would allow his magically contained and compressed form out, bit by bit. They would be able to wrangle the unruly ophidian organ at a smaller size, and when he had become obedient and would obey them, they hoped to have a full size naga stemming from their body, a massive maleness that could do as they wished, even though they would be left to rest in one spot while he was erected from their vagina. That was the plan, anyway. Physically, it could work, as they knew the compression spell upon the serpent would work to stow all of him away inside their body, even when he was full-sized, and they weren't aroused. Taming Amethystine would be another matter entirely.

After turning the alchemist into their snakeshaft, they headed back home and poured a pre-made potion the pair had prepared into a small bowl. It was going to make their 'joint relationship' with the lamia longer-lasting than their temporary magicks.

As they held their sensitive and semi-scaled cockhead in the bowl to force their phallus to suck up the serum, the hydra leaned back on their knees, giving their new member a few strokes while they imagined what was to come next, barely able to contain their excited anticipation. They could have cum right then and there, but they knew they needed the former naga to drink the concoction.. despite how delightful the feel of the fluids flowing up (or was it down?) his throat - their urethra - was.

~

Part 3

A few comforting strokes soon turned into a full blown masturbation session with their new cock, necessitating a quick trip to their bedroom, where the fledgling snakey genitalia tried out his cock-tongue on his hydra hosts, with their coaching and coaxing.

While Amethystine still wanted to be free and regain his normal form and independence, as the melange of hormones rushed through his phallic form, he found it increasingly hard to resist the urgings from his twin captors. As the siblings' celebratory binge of constant carnal games began in earnest, the serpent was locked away in a penile prison of pleasure.. their arousal affecting and infecting him, so he only had fleeting glimpses of the light that was clear-headed, sexless sobriety.

~

Part 4

A few days passed, the terribly horny twins spending their every waking moment playing with their Amecock, toying with him.

They did so figuratively, and they also did so literally, using toys on him.. both plunging objects into him and thrusting him into many a tight and squishy space.

~

Part 5

As Rhylith and Torri continued to have their blissful fun, the potion was slowly wearing off, allowing their snake-cock just a bit more clarity. Those snatches of reality, instead of the more physical sort of snatches Ame was buffeted with, arrived unto him after each mind-bending orgasm had slunk away.. and before that same beast came back to once again consume his entire form.

~

Part 6

As time went on and the hydra reached ever-higher levels of hedonistic excess, they lost track of time. And as time marched onward in a haze, the potion keeping the python anchored to their anatomy began to wear off, causing him to slowly grow toward his full size while still firmly affixed to their flesh. Both due to their confusion as to what day it was and their old plan of taming the constrictor and then allowing him to regain his old massive proportions, Torri and Rhylith took no real notice. They were unconcerned with the swelling snakemeat they sported, only becoming further lost in their own lust, thanks to the increased intensity of their activities that went along with the burgeoning boidae-boy-bits.

~

Part 7

At the end of the lengthy week of delightfully depraved debauchery, the twins finally came to terms with the extraordinary size of their serpentine member, realizing that they should be making the snake take another dose of the draught that was keeping him enmeshed as part of their flesh.

Only barely managing to control themselves long enough to stuff their sinful scales as far into the vaginal sheath in which the shaft was meant to reside as they could, the twins concealed the remainder of the reptilian rod under a loose coat for their journey back to Amethystine's laboratory.

Upon sitting at the alchemist's work-counter, amidst his beakers and burners, the blended draconic deviants attempted to focus on recreating the formula that would ensure further flesh fastening. And while they concentrated, their cock could finally think, as well. No more nagging need to nudge and nuzzle into nooks and niches the naughtiest sort. The serpent was no stranger to merging or the potions that went with it, so he realized what they were up to, and how close he was to regaining his freedom from the heathen hydra.

Soon, Ame had a plan.

It was a little while later, when Rhylith was in the middle of trying to recall the next ingredient in the recipe, and Torri was trying to jog her brother's memory when their maleness slithered up between their breasts and wound around to nose needily at the nipple upon their blue breast, hissing and sucking and licking as best he could with his turgid tongue.

Catching the twins off guard as well as in a moment of weakness, it didn't take much for the serpent to draw them into a repeat of the ribald rubbing and rousing writhing they had been engaged in all week. The sudden intense encounter with their suddenly willing nethers rooted the pair to the spot, amazed at Ame's attitude change. Beginning to both become too preoccupied with the pleasure, they also began to believe that the need for the new dose wasn't too desperate. Clearly, their cock had come to accept his new position as their pleasurable plaything.. or at least, he couldn't resist more of the lovely, lustful fun they had given him, wanting more as soon as it had stopped for any amount of time.

The python got what he apparently wanted, and the twins took a little break to bask in the ecstasy that their lengthy, girthy guest provided. Then they got back to work.. until Amethystine began gently winding around them, rubbing his smooth form along their fine-scaled skin, tempting them back into another break not long after the first. With goofy grins, Torri and Rhylith gave in again, unable to resist the siren song of their own sex.

After another period of work, they certainly couldn't argue with Amethystine's snout sinking into their female sex, abruptly. Thoughts on whether or not one's body could molest itself were lost in a fog of masturbatory movements while their cock wore them out, little by little. After the week they had put themselves through, it didn't take the sneaky shaft much effort at all.

Eventually, while straining to read a dusty tome filled with information on making magical melanges, Rhylith yawned, muttering, "I'm so tired.. Hmm, Torri? You'll work on this, right..?" he asked, snuggling his head up to that of his sister, his cool blue arm hugging over their shared front. His yawn was catching and it made her join in with a stretching of her own jaws as she snuggled against him in turn, letting the book drop flat on its back on the counter in front of them, their conjoined form sitting slouched but upright on the stool.

"No.. I'm too tired.. you do it.." Torri murmured back to her already slumbering brother, promptly falling asleep after uttering those words, unaware that they had fallen upon Rhylith's deaf ears.

Part 8

Upon seeing that his cruelly carnal captors had lost their grip on consciousness, the cock sprang upwards, into action. He stretched carefully over the counter, trying not to allow his possibly arousing movement to awaken the twins. They stirred now and again, but they were far too used to sexual stimulation after the week they had with their fleshy toy.. not to mention their long-honed ability of being able to disregard what one half of their body might do in bed as the other half slept.

The pythonic shaft needed to work with the material that Rhylith and Torri had been preparing, which was intended, of course, to re-cement their merge with Amethystine once more, to deepen and strengthen it. Working hastily, the snake was forced to only make an attempt at altering what was already present in the potion in progress, aiming to give the serum the opposite effect and allow him to continue to grow back into his old shape and eventually detach himself from the deviants.

There was only so much precision the maleness could achieve as he manipulated vials and beakers with his mouth and meaty tongue. He forced himself to take breaks, allowing the sleepy level of arousal that coursed through his cock body to lessen, lest he become too stiff to carry out his task properly at all.

When Ame deemed the draught as ready as he could make it, he latched onto the tube at the top of the small glass container and flicked his phallic form upwards to upend it into his toothless maw, his penile tongue winding around the neck of the miniature bottle. His own excitement at his imminent escape caused his form to fatten and his tongue to leak, pre dribbling over his lips as the more important fluid flowed down into his urethroat. The concoction cascaded through the cock, causing the red and blue 'beasts' enough stimulation to be pulled from their pleasant little nap.

~

Part 9

Torri was the first to really react in any noteworthy manner.

A red hand reached out toward the brown scaled and veiny column that stood before her, extended up from between her and her brother's legs. She could see her member's mass skyrocketing, like the most majestic erection.. but she knew, despite the lovely, lustful sensations of the girth grinding against their thighs and the lip of the counter, that something was wrong. Her hand, originally intending to grasp the thick, voluminous maleness, found there was suddenly too much volume to wrap one's fingers around, and merely pawed ineffectually at the wide, cream-coloured scutes that were rapidly reforming on the serpent's front.

Amethystine was twisted around, so that he was facing the groggy pair, able to see as Rhylith came around as well, sitting upright, out of the sleepy slouch he had adopted while snoozing. The blue boy balked at the situation and also tried to snatch at the snake, finding that to be partly foolhardy, as they were still all firmly attached. Realizing that it might not last, though, Rhylith's next target was something, anything, on the workbench behind his ever-expanding maleness, which would halt the process in progress before him. Surely there would be an emergency cancel all type of potion. All apothecaries had them, for when things went wrong, a formula derived of nothing but a mixture of agents known to arrest all alchemical avenues.

The short haired half-drake was shocked to find his arm shoved away by Amethystine's own re-materializing limbs. One good shock deserved another, it seemed, as the python then braced his bulk against the tabletop and pushed his lower body away from himself, toppling the twins off of the stool and sending them sprawling, thanks to their crotch being as much a part of his lower regions as the rest of his coils.

One would imagine that the hydra would have landed squarely on their tail, but they had collapsed face-first, due to how the naga had applied twisting torque to his expulsion of his oppressors. His serpentine spine had been rotated around to be able to face them as they sat on the stool, and in his effort to straighten his own form out, his antagonists had been flipped to flop onto their front, both groaning softly at the mixture of pain and pleasure at being man-handled by their own manhood.

Lacking the length to truly distance himself from the conjoined siblings, Amethystine also tumbled down after them, landing between their outstretched legs, under their up-turned tail.

The python peered at the pair with some contempt as their arms shifted and tried to push at the ground, to lift themselves up once more. The cock's coils were coming back to him and his mass was steadily slipping past what the twins could handle without assistance from the actual owner of the loops. Amethystine's derision led to a decision, he was determined to devise a demonstration for the deviants about why one should not kidnap and cock-ify a constrictor conjurer of his caliber.

Finding that he had the upper hand with his increased and continually increasing weight, Ame anchored the softly squirming draconic double team down on the ground as he considered what he could do to use the pair for his own express pleasure. He realized that it wasn't exactly the sort of justice most people would strive for, but he thought it was fitting. While contemplating their comeuppance, he considered the concoction he had created to put things back to normal, out of the one they had been making, pondering how the proper potion for cancellation and for reversal might have ended up much differently, despite being similar in composition and in intent.

At that moment, when struck by a sudden thought, he had his solution. Or at least the beginning of the lesson he wanted to impart.

Standing up, the reptile returned to the counter to work on another potion, his skills bolstered by his newly re-acquired arms. The serpent's body was still reforming and his tail was still lost deep within the hydra's husk.. which he was counting on.

Before their bodies parted ways, Ame finished a new mixture and swiftly threw it back, the liquid lancing down his long throat, heading deeply into his merged mass. Almost immediately, the soft sensations of sliding sinew and slithering scales ceased, then began once more, in a slightly different direction. It was as if the transformation itself had gotten lost and confused momentarily before continuing down a new path, forging a new trail, rather than retreating back along the one it had originally trod down.

Amethystine's tail had been gradually grinding its way out of the hydra's snatch, where the snake's body had made its home for the previous seven days or so. The molasses-like motion had been causing the twins tortuous, unfulfilling pleasure in the process, which was accompanied by mental anguish as they had felt their greatest sexual conquest slipping away. With the serum's stoppage and new aim, instead of re-creating the naga's tail bit by bit, the metamorphosis seemed to lock the tapering serpentine body in place, suddenly fusing the feminine folds where they sat stretched around the thick snake tail. The sensitive entrance to the hydra's body did not disappear, though, and the twins were forced to feel the muscular flexing of Ame's body teasing them, unable to hump up and down his length as they so desperately wanted to.

Meanwhile, their long, smoothly tapered and two-toned tail was losing both its loyalty to the lusty siblings, and its colours. It shifted allegiances to the Amethystinian side of things, pure red and blue fading into a gold-patched brown with an off-white belly.. a belly that was upside down. The naga's scutes were appearing on the backside of Rhylith and Torri's tail while his body rotated within their plugged pussy, causing them more un-actionable arousal as the re-orientation of the serpent made scales slither slowly along their slit and clit, stirring them up.

When his body finished re-aligning and their tail had become his, it looked like the snake's body merely intersected with that of the hydra, rather than belonging to it.

Stretching the end of his form out and wriggling it about a bit, clearly pleased to have it back, the python then used it to prop up the still sleepy siblings, the slender extremity curling between their necks to gain purchase. As the strong, thin wisp of scales nestled between the bases of the draconic necks, they gasped and shivered in pleasure, squirming anew as they became more alert. After a short delay, the python purred as well, a jolt of joyous sensation shooting up from the portion of his tail that felt like it was embedded in the hydra. He was suddenly able to receive feelings from their flesh, just as they had been receiving from him throughout the week before.

Both Rhylith and Torri's legs came to life from their slackened resting places to clench around the thick body that protruded from their cunny, both of them moaning until the serpent's tail had removed itself from between their apparently super-sensitive necks. Ame slipped it away, as they were quite capable of keeping themselves upright, with the unexpected wake-up call.

Just about to try to tell the pair off, the python was reminded of his mute nature as the thick shaft of his tongue re-introduced itself, swiftly growing hard from between his lips, thanks to the recent rousing revival of the red and blue creature. They were still in transition, and Ame's form was still a phallus to them. He glared at them as they grinned and rubbed their own breasts, mocking him a bit with even more self-stimuli.

The naga had a reason to smirk around the swelling spire in his snout, though, as he groaned at their tender touching, able to feel the sweet caresses as well. The pair looked puzzled before their necks grew stiff and were made to lean somewhat apart in a 'V' orientation.. quickly swelling thicker, looking particularly turgid when a number of veins raced up their circumferences. Ame grinned and used his tail on their transforming shaft-necks, urging the production of their own organ-tongues.

Perhaps because he was the true male of the merging, Rhylith's deep blue cockhead sped ahead, leading a thick column that crowded the hydra-half's mouth wide open, muffling his protests and groans. Torri felt over her neck with a worried expression, made even more concerned by the sight of what was happening to her brother.. yet she too was unable to keep herself from murmuring soft coos of pleasure at the feel of it all.

Amethystine believed his lesson was off to a good start...
