As one dragon finds out sometimes things are hidden deep in the jungle for a reason, so as not to be disturbed...

A silver tiered commission for teryxc, who also stars in this story!

Also, there just simply is not enough symbiote action out there nowadays, that needs to be rectified.


Teryx walked quickly through the wooded terrain, a frown on his muzzle as he looked down at his GPS. He had been hiking for three solid days now and had gotten thoroughly lost, and with the thick canopy of trees he couldn't get his GPS to hone in on his signal so he could try to get to the nearby town. He knew all he had to do was find an open enough spot to get a fix on his position, even if it meant that he would have to leave his quest behind.

The rain dragon had been visiting a little village on the edge of an expansive, untamed plateau for a week during a festival they held and had heard rumor of a beautiful waterfall that weathered stones as smooth as glass, and came with a dazzling array of colors. Not one to pass up a chance for a free souvenir he took his backpack and supplies and ventured out into the wilderness, confident that the area they spoke of couldn't have been too far from the village. Only now as he slashed his way through another bush did he realize that when they said the location was 'somewhere in the general area' they were being more than vague, to the point where he wondered if they knew where the spot was at all. To make matters worse the GPS he had relied on to get to the area started to fritz out, which meant that he was stuck until he could find a clearing or the way back to town.

"Thank goodness I brought all my stuff with me," the dragon huffed to himself as he pushed his way past the foliage. "I'd be in a whole load of trouble if I simply assumed this would be an easy day trip. I can't believe how far off these locals were, though my first clue should have been the reluctant look on their faces that they didn't know exactly."

A few minutes later he hacked a particularly dense grove of thistles to find unfiltered beams of sunlight shining through, over his muzzle and chest that warmed his scales. He could feel his hope growing as he cut a big enough hole for him to pass through, then carefully threaded his way to the other side. He ran his clawed hands through his golden mane as he reached the other side and whistled at what he saw.

It was a scene just like they had described, complete with waterfall that splashed down into crystalline waters of the lagoon beneath. Just seeing such a sight had been worth the trip, especially when he went down to the shore and picked up one of the stones that the locals had talked about. "A nice little memento for me," the dragon said with a chuckle as he slid it into his backpack before he looked up at the clear blue sky. "Plenty of clearance for me to get a proper signal so I can find my way back... although it would be a shame to have wondered all this way just to grab a rock."

The fine-scaled dragon gave a cursory look around before he undid the buckle of his cargo shorts and let them slide to the ground, followed by his shirt that he tossed to the side. His sky and blueberry colored scales glinted in the light as he slowly slid into the clear water, which was cool and refreshing as he waded in deeper. Once he had gotten used to the temperature he dove down a bit, playing with the rocks on the bottom before he would return for air. Every time he came up he went closer to the waterfall itself, then as he was only a few feet away he found that the water there was only about a foot deep as he climbed up on the stone shelf.

Teryx opened his arms and let the force of the water cascade over his naked body, feeling a smile creep along his face as the last few days of traveling seemed to wash away. Once he had gotten his fill of that he sat down on one of the rocks that jutted out of the water to take a short breather. As he let his scaled bulk dry in the warm air, he looked up at the walls and noticed a whole sequence of pictures etched into the stone. At first he thought it was graffiti but the closer he got the more he realized that they were far more intricate in their carvings.

"Huh, looks like these stick figures all worshipped this... shadowy figure... maybe the chief... could see that being their deity too," he mused to himself as he ran a finger over the etchings as he moved to the next set of images. "Ah, definitely deity, looks like this one in particular is performing some sort of ritual for the shadowy thing, and then the shadow moves on top of him." He traced down to the last image, which showed an almost monstrous figure that once more had a group of people around it. "I guess it gave the dude its power here and now the chosen one rules over them? Man sometimes I wish I could just see what the ancient people were thinking when they thought about this kind of stuff."

Unbeknownst to the rain dragon a puddle of blackness glided through the otherwise crystal clear water, heading over to the creature it had sensed entered the waters that served as its prison. Silently it settled around the dragon's submerged legs before the black substance started to defy gravity and began to crawl up the dragon's shins. By the time Teryx looked down he was covered by the oily substance all the way up to his knees, the inky blackness seeming to pull him and his brighter colors into itself. In his panic the dragon flailed uselessly to try and escape and fell over backwards, his feetpaws still firmly suctioned to the bottom by a strange force. As soon as his body hit the water the black puddle immediately began to extend down the length of his form, the dragon keeping his head up to prevent any of the substance from reaching his head as he felt it latch onto his scales.

"Get off me!" Teryx shouted as he struggled to get out of the shallow pool, only to find that his hands and arms had become completely encased by the rubbery substance up to his biceps and had tentacles of the same material curled around his wrists that pulled them back down. The same thing happened to his legs and he watched in horror as his feet seemed to swell out, the claws on his feet lengthening even more until they became a set of thick talons. His breathing quickened as the black ooze covered his chest and abs, the skin underneath buzzing with pleasurable tingles as every crevice of his musculature was coated in the strange substance. The dragon knew that screaming was unnecessary, there was no one around for miles which meant he had to try and fight the thing off himself.

With a mighty effort Teryx strained to get his hands out of the water and after a herculean effort he finally managed to get them above the surface. His joy was short-lived though as instead of being able to help himself get out of the water his arms seemed to move of their own accord and stroke down his latex-covered chest before they finally stopped on his groin. Even though it was below the water he could see that the alien material had already completely covered his crotch, which had already grown erect as the shiny black head of it poked above the surface of the water now. His back arched as his hands began to stroke the spire of rubber-covered flesh, causing him to almost dip his head below the water before he realized what he was doing and jerked back up.

"Oh my, you are quite the fighter." a voice suddenly said. Teryx looked frantically around for the source of the voice before he saw a mass of the black ooze rise up from his chest and form into a vague demonic shape like the one on the cave wall. "I take it you have not intentionally offered yourself to be my vessel then, hm?"

It took a few seconds for the dragon to process the surreal situation, then nodded frantically. "Yes, so sorry, but this has been a big misunderstanding," Teryx stated with the best sheepish grin he could put on despite the situation. "I just came here to enjoy the scenery, maybe get a memento of my time here in this wonderful land. If you would just let me go then I'm sure we can put this all behind this as a mistake."

"Mistake or not, you are still in my realm and have bathed in my waters." the inky creature hissed, the rubbery coating that was already around his body seemed to tighten as his knees and neck that were still above the water started to have the rubber creep up on his scales. "You have also broken my imprisonment when you displaced one of the rocks that kept me captive here, but I am still unable to leave this place without the aid of a vessel. You will be that vessel, and with it my tool to exact the revenge that I have been wishing for ever since I was put in this accursed place."

"Please, I didn't do anything to you," Teryx pleaded, trying to focus on the conversation despite the fact that his hands still pumped on his growing cock without his direction.

"All those who walk in these lands now are to blame," the creature continued. "I lived as a god amongst my people, delivering my strength to them in exchange for their worship. Then the invaders came and despite my best efforts they slaughtered everyone and imprisoned me with their foul magic in these waters lined with sacred stones. You may be an outsider, but I need your form to reach those who deserve my wrath."

Teryx could feel the anger in the ooze that covered his body as his hands once more fell to his sides which allowed him to think straight again. The rain dragon sympathized with the creature's plight but the fact he couldn't move most of his body, which by now had almost been completely covered with the rubbery substance, gave him pause. By now the creature had also completely crept up his neck, to the point where he could feel tendrils of it begin to hook into the corners of his mouth and started to coat his teeth and cheeks.

Then, just as suddenly as it started, the assimilation seemed to slow to a near stop on his body and he could suddenly feel control return to his limbs. Perhaps the creature felt his empathy towards him, he thought to himself as he slowly sat up. By now the shiny black substance had almost completely covered him and every inch of his body glistened as the rubber seemed to accentuate his features perfectly. It was an extremely erotic experience, he thought to himself as he ran a larger hand down his chest, murring as he felt the synthetic substance rub against itself, especially when he reached his cock. Before he succumbed to the feeling of pleasure of his new larger endowment the thought of what the symbiote wanted to do crossed his mind and he frowned slightly. Though he was starting to grow to appreciate it he wasn't sure what the symbiote would want for such an exchange of power...

The dragon suddenly gasped as the heaviness in his limbs returned with a vengeance, his cock throbbing as he felt the rubber once more begin to shift over his body as the rubbery demon head shook in mock disappointment. "You can't do this!" Teryx shouted as the symbiote grinned evilly. "I won't let you just take my form for your revenge!"

"Go ahead, I love to feel you squirm." The entity replied with an evil smirk, Teryx gasping as he felt the tip of something brush up against his tailhole. The face of the creature leaned in what looked like a kiss, and as it did he felt the two latex tentacles that had crawled up his face to push against his jaws and brace his mouth open. His eyes widened as he watched the creature's proto-muzzle push entirely into his stretched open maw, a muffled gasp was all that could escape his throat before he felt something slick push down it. The rubber-covered scales of his neck bulged as more of the strange substance was slathered over his tongue, his teeth, and the rest of his mouth as the creature pulled his head back while the thick tentacle was still lodged deep in him. The dragon was unable to resist as the featureless face seemed to mimic his own for a second, opening his mouth in a roar and then stretched unnaturally open before it lunged forward and clamped down on Teryx's tentacle stuffed maw. Soon the dragon's muzzle completely enveloped by the entity's head as it pushed over him like a mask, stretching out until it covered his entire face and joined with the rubber that had already begun to assimilate his mane. At the same time the appendage that had continued to prod under his tail began to push inside him, causing his entire body to shudder.

As the ooze began to creep over his eyes Teryx could begin to feel the presence of the creature in his mind, the rubber pushed into his large ears as it reached and began to convert his brain. The water churned as his rubber-covered body writhed, tendrils pushed down deep inside him and into his muscles and organs. He realized in horror the creature wasn't just covering his body, it was completely converting it as he suddenly felt his groin twitch. Though his vision was fading like the control over his form he could see two small tentacles push out beside his mutated cock and begin to wrap and slide around it. The stimulation put the dragon back into a fog of lust, his mouth opened slightly in pleasure as his black rubber teeth pushed out until they were a pair of wicked fangs while his tongue slid out to an unnatural length past his lips.

Teryx struggled to fight this invader, but he had already lost control of his body and as his vision continued to fade he could feel his mind slipping away into darkness as well. It was a strange sensation, while he was still completely aware of everything that his body felt and heard and tasted he had no control over it except for his eyes. As he dwelled on what little he had left he heard a dark chuckle from the corner of his mind and even through the haze of pleasure he felt with some ire that the symbiote was letting him watch his own losing battle.

As though to accentuate how right the dragon's thoughts were Teryx suddenly felt the thing that had been teasing his tailhole begin to push inside him. His anus seemed to stretch almost eagerly to take the thick appendage, something the creature had no doubt already done to him, and as his focus was on the filled sensation of his backside he could feel his latex tail begin to shift and writhe. The rubber-covered tail lifted out of the water to allow him to watch as a cleft formed at the tip which deepened as it ran a foot up his tail. All he could do was watch as it split into two, then those two parts grew a similar split until the end of his tail was four thinner rubber versions of itself.

The shock of how alien his own body was mutating into gave Teryx the strength to will himself to try and stand, and was amazed to find his body slowly responding to the command. His partially converted eyes looked over at his duffle that contained the prism stone, which was on the other shore. His mind churned as he stood up, feeling new cords of muscle stretch as his already athletic body had grown at least a foot and packed on more than a few pounds of muscle. Despite his better instincts the word 'beautiful' came to mind, his eight-pack and chiseled pectorals, and his huge arms and legs screamed power but wasn't at the point of grotesque like some bodybuilders he had seen in his travels. He shook his head though and slowly began to walk towards the edge of the cave, and though each step felt like he was waist deep in mud he was making progress.

"You have quite the spirit," the entity commented, though this time Teryx was horrified to hear the words come out of his own mouth. "Do you really think that just replacing the stone and taking another bath is going to shake me off of you? I grow stronger with every passing second. You have such a wellspring of delicious energy, it's what drew me to you in the first place when your form entered my waters."

A deep lump formed in the pit of Teryx's stomach as he heard that. Had this strange creature been feeding on him since the second it made contact with him? Was his efforts to try and get back towards his bag only powering the entity even more as he expended his energy? As he reached the edge of the water he felt the skin between his hands and his massive paws itch and when he looked down at them he saw that transparent black webbing had formed between the digits as his fingers lengthened into larger hands.

Teryx jumped into the water and began to swim towards shore, but as he did he could feel the weight of his new body began to quickly drag him down and he struggled to keep his head up. "Alright, you made your point I suppose," the entity spoke finally. "I'll tell you what, you stop struggling and as my thanks for freeing me and to keep us from delaying any longer with your pointless escape attempts I will relinquish control of your body once I find a new vessel. Then I shall be free to enact my plans and you can go about your traveling ways. Agreed?"

The assimilated dragon stopped and treaded water as he mulled over the proposal. While he wasn't sure he wanted to visit this fate on someone else it would give him his own freedom. He carefully weighed the options in his mind and after a few minutes he mentally gave his approval of the plan despite his reservations. His head sank beneath the surface of the water as Teryx's eyes widened before they were completely coated in black rubber, which caused him to sink into darkness as well. As he felt himself float there another presence flooded into his already corrupted mind, feeling the powerful will of the symbiote easily brush aside his subconscious. He quickly realized he definitely wasn't in control anymore as he could see again, only now everything was tinged with red as he felt the intense instincts and thoughts continue to wrap around him...

For about a minute everything was still, light reflecting off the water before the tranquil surface was shattered by Teryx's emergence on the shore. Two sets of eyes on the demonic dragon's head blinked away the water, one pair was Teryx's original that were now a solid gold rubber while a second pair was nestled behind it that glowed with a bright red against the reptilian pupil. The mane of golden hair had grown substantially until it threatened to overwhelm the curved rubber horns and cover the creature's face.

As water dripped off his muzzle he stretched out his tongue to catch some of it, the appendage stretching out to wrap around his entire muzzle and brush against his wicked fangs before it retraced inwards once more. The coloration of the rubbery skin had changed as well; from the original black it had adopted Teryx's color scheme, although now there were red runic symbols that trailed around his body to create intricate patterns all over his new form. The last new addition was four thick, deep blue rubber tentacles that formed around his shoulders and two smaller ones that grew from his snout like whiskers that twitched with every move. The creature flexed his back and a pair of huge rubber wings unfurled out and began to flap out of the clearing and into the sky, making a beeline to the small columns of smoke that were outlined in the setting sun.

**********************************

Night had fallen and the heat of the day had finally broke enough that walking outside was now a pleasant experience. The whole town seemed to be out and about still as they celebrated a liberation from an evil oppressor that happened centuries ago. Unfortunately for Tak he was not one for festivities, the leopard had left the bar where his friends had dragged him to drink and was now on the fastest route back towards his home. With everyone out and about he wasn't afraid to take a few shortcuts through people's lawns, though it did bring him rather close to the untamed jungle. He had lived next to it his entire life though and didn't fear it or anything inside it, though he didn't know what skulked about as a pair of glowing red eyes watched him through the bushes...

Tak wiggled through a wall of thick bushes that formed a natural fence for the backyard that it contained, the light that shimmered off the pool cast the entire area in an eerie glow to it as he crossed over the well-manicured grass. About half-way through he heard the sound of wings and a loud thud that caused him to turn around in a panic, only to see a blue scaled dragon land a few feet behind him. Though Tak could still feel his heart race he recognized the male as the tourist that was staying at the inn next to his house, he had even had a few conversations with him while they ate breakfast outside.

"Teryx, my friend." Tak said as he continued to breathe heavily from the scare. "Where have you been? I thought for sure you were going to miss the final day of the festival when you went out to try and find that pool... Teryx?"

Teryx just seemed to smile as he slowly approached the leopard, and as he did the feline started to notice that the light from the water rippled across the other male's scales in a rather odd pattern. The leopard started to back away as the dragon's form shifted before him and saw that his eyes were solid orbs of shiny gold, but before he could turn and run something darted out from behind Teryx and wrapped around his wrists and ankles. As Tak was forced onto his back he saw that it was the dragon's tail that held him against the grass, though it had somehow split into four rubbery appendages as a second pair of eyes opened near the first pair that glowed red as they looked down at him.

"Yessss... you will do just fine." A deep, disembodied voice said as his tongue slid from between lengthening incisors that dripped with a bluish-black substance. Tak quivered as he tried to squirm out of the grasp of the tail only to find the tentacles that bound him were freakishly strong. "No, please," the leopard pleaded as the possessed dragon's muzzle leaned towards his own. "Don't do thi-mmmmrrfffhhh!"

The leopard's cries were muffled as the Teryx's tongue darted forward like a snake and pushed into the other male's maw. Tak's eyes nearly rolled back into his head as his back arched from the latex appendage in his muzzle, which had already begun to snake its way down his throat as they could both see the lump travel down towards his chest. More and more of the guise that the symbiote had put on began to fail as tentacles sprouted from his shoulders, which quickly slithered down and began to wiggle underneath the leopard's shirt and shorts. They made quick work of the fabric, tearing it away as the naked male writhed underneath the physical and mental assimilation from the symbiote as black rubber began to leak out of Tak's nose and his muzzle began to deform slightly.

As the leopard male moaned Teryx lifted him into the air, suspending him from where the dragon's tail wrapped around him. The ridged, rubbery cock between Teryx's legs was already hard by the time Tak's tailhole got close to it and when it got close the member began to stretch out. The tip deformed slightly as it continued to reach for the tight ring of muscle and by the time it rubbed its tip against the opening the thick cock had grown into a long pink tentacle. As it slowly pushed inside the leopard's body jerked in his bindings, though by now the feline looked so blissed out it was only an occasional moan and body twitch that proved he was still conscious. The two tentacles next to Teryx's cock pushed out and rubbed the leopard's now-hard cock as well, overstimulating the poor feline as his body twitched and convulsed.

Inside the dragon's head the real Teryx found himself released from his own prison of lust and looked down to see what was happening to the leopard. "I should have known you would choose someone like him," he grumbled as he watched the blue rubber begin to meld with the fur on Tak's body and cause it to lose its texture. "When do you leave me?"

"Soon..." the symbiote rumbled and Teryx suddenly felt an intense jolt of pleasure from his transformed tongue and cock tentacle that continued to penetrate the leopard's body. "The bonding process is nearing completion, until then just enjoy yourself." By this time if he had his physical form he would have been on his knees as he felt the sheer power of the symbiote as it corrupted the other male's body. As his muzzle leaned in, tongue still buried deep in Tak's throat, the tentacle whiskers on the sides of his snout darted out and began to wiggle into the furry rounded ears of his friend.

Teryx wondered if Tak was experiencing the same thing he had now, the feeling of the host's powerful psyche in his mind as he felt his body get coated in thick, shiny rubber. The symbiote's mutated cock began to thrust into him in earnest and the dragon couldn't help but nearly lose himself in such wonderful pleasure. The dragon was slightly surprised that the substance that covered the other male had retained its blue color, even going so far as to turn a lighter blue at the chest. As the leopard's head was coated he watched as sharp, wicked fangs grew out from his stuffed feline muzzle, which had started to look a little more reptilian with tentacles like his growing just above his lips. A pair of horns grew out from behind Tak's ears as they became longer and tapered, framing a flowing mane of synthetic golden hair that ran all the way... down his back...

Before he could even raise the question Teryx heard the soft, dark chuckle from the symbiote. "I do adore the changes I made to your body, so I figured I'd keep them," it said as the average chest of the leopard swelled while the outline of tentacles could be seen pressed against the growing pectorals underneath shiny rubber scales. "I can do what I want with my hosts after all, don't you agree?"

Teryx strangely found himself agreeing before the symbiote seemed to once more direct his attention to the transforming male still strung up by his tail. By now the leopard's head had completely transformed, the tentacles still wiggling in the mouth and ears of an exact copy of the symbiote Teryx's visage. That rubber had also cascaded downwards and coated Tak's shoulders and back, the leopard squirming pleasure as a pair of large latex wings pushed out from the pool of dark blue rubber on his back and more tentacles burst out from his shoulders. Teryx found himself strangely admiring the visage of the leopard's new form as a thick layer of rubber coated over the feline's tail and it swelled outwards into a proper reptilian appendage while the ends split into four just like his did.

As Teryx's rubber body began to thrust harder and more erratically he saw something that managed to cut through the intense emotion of the rutting; a pair of demonic red eyes that formed just over the rubber covered orbs of the former leopard. Was this it, Teryx wondered as he felt his entire body tense up with impending climax, was this going to be when the symbiote would relinquish his hold on him? It wouldn't be long for him to find out, a monstrous snarl left his lips as the newly created demonic Teryx was pushed into the air while the original dragon let loose a torrent of seed in his tailhole. Had the festival not been happening their orgasm would have been heard for blocks as Tak's hole was filled with the symbiote's seed.

Teryx felt control seep back into his form as Tak stood up, the demonic dragon symbiote looking over what was now an exact replica of his own body. "Such compliance, almost makes me wish I had found this one first," the symbiote purred as he reached up and stroked Teryx's latex cheek. "Of course you had the power to quickly revive me, I wouldn't have been able to do this without you."

"Yes, well, you have your host," Teryx replied as he felt a pang of guilt for his friend, who no doubt watched as they finished their bargain. "Now if you'll get yourself off of me I have a flight to catch, I don't think I want to stick around while you enact the rest of your plan."

"Oh my dear boy, who said anything about giving you your old body back?" The symbiote said with a laugh that chilled Teryx to the bone. "I've changed my mind about letting you go, and your good friend Tak doesn't want you to leave either. He loves what he is becoming and thinks you should definitely stay and join him in blissful servitude. Now kneel and accept your position as one of my hosts."

Teryx gasped at the betrayal and tried to turn and run, only to feel his body become awash with pleasure. Without even realizing it he found himself on his knees, looking up into the glowing red eyes of the symbiote as he placed his hands on his face. "N-no... you said..." the dragon said as he felt his limbs grow heavy, unable to look away from those glowing orbs. "You said you'd release me..."

"No, I said I'd give you back control of your body," the symbiote replied with a bemused grin as his ridged rubber cock pointed straight at Teryx's lips. "It's far easier for me to control your mind when I can actually look at you. I know you don't think that's fair but I really don't care, if it makes you feel better -- even if we had struck some ironclad agreement I would still have kept you as one of my hosts anyway."

Teryx wanted to protest, but oddly he felt... rather good that the symbiote had decided to keep his body. Even though he was primarily controlling Tak's body now he could still feel those psychic tendrils embedded in his mind, fueled by the pure allure of those eyes that watched him as he slowly opened his mouth and began to suck on the hard member. As though to reward him for his obedience he felt another surge of pleasure, then another as he felt what was essentially his own maleness fill his maw.

The symbiote groaned, partially from the feeling of both warm muzzle on his cock and a cock in his muzzle as he shared the experience from both males. The last of the dragon's resistance could almost be visibly seen draining out of him as his tentative sucks became an earnest head bobbing that pushed rubber scales against one another. Their tails wrapped around one another as the symbiote coaxed the former leopard's body to a quick orgasm, the two rubber demonic dragons moaning and writhing as the symbiote linked their orgasms so they both felt them.

When they finished the two symbiote-controlled bodies stood up and their rubbery features retreated back into their body, which left leopard and dragon standing there with glowing red eyes. With less appendages to manage the symbiote was easily able to take direct control of them both, and in unison they bounded off back towards the festival. It took all the symbiote's power for them not to have raging erections when he ran there, he wouldn't want to spoil the party with such lewd actions...

...especially since it was his defeat they celebrated.
