Author's Notes: Over two decades ago, Rangarig Rex released the adult animated short Raplab 200-<4>. It was the fourth installment of Raplab and with a running time of nearly 17 minutes it was, and remains, his longest animation to date. It was released on DVD with some bonus scenes in 2009 in limited quantities to commemorate its fifth anniversary. Rangarig is one of the artists who really helped define early 3D rendered furry content and is someone I have a tremendous amount of respect for. Our paths crossed a couple of times during my original stint in the furry community and he's someone I've always wanted to collaborate with, though it seems that he has mostly retired from creating things (and while I still do create myself, obviously, I'm kind of keeping things "hands off" on all fronts).

That said, one thing I always wanted to do was adapt one of Rangarig's animated shorts into a story. I figured the best candidate would be his most well known work. The "N" in this submission's computer-esque title is meant to be a stand-in for "The Novelization", such as when you'd see a blockbuster movie have a book adaptation printed after the fact with that moniker as its subtitle. This story follows all the same main beats as the animation it's based upon, though much like the aforementioned movie books there's a little bit of "connective tissue" that I've added either to help link some scenes together better or to more clearly establish a narrative. I changed as little as possible.

I highly recommend you view the original short some time. It might be 22 years old by this point (and looks the part) but as far as technical accomplishments for their time go it's very impressive.

A velociraptor laid splayed out on his back on an examination table in an operating room. From a neighboring room, a bespectacled peach-colored dragon in a laboratory coat looked on from his seat at a computerized control panel behind a one-way mirror. The badge hanging from the dragon's coat identified him only by his assigned codename, "Variant-B". His colleagues had graced him with a catchier nickname that he begrudgingly accepted however: Varby.

If the velociraptor strapped to the table in the operating room had a name, Varby didn't know what it was; the computer terminal in front of him simply identified the raptor under the moniker Varby's superiors gave to the dinosaur when the he was captured and brought into the facility, "RaptGenM". Even if the raptor wasn't sedated Varby wouldn't have been able to figure out his name anyways given the most his kind was able to do was growl, hiss, and roar. Velociraptors were generally renown for their above average intellect as far as the surrounding wildlife was concerned, and they were observably able to speak to one another in a form of complex language, but there was still a chasm of knowledge separating RaptGenM from the scientist watching over him.

The fluorescent lights in the operating room filled every cubic inch of air with their incessant buzzing, a wall of noise that gradually reached a crescendo where it pierced the veil of unconsciousness covering RaptGenM. The dinosaur stirred, rumbling audibly as he felt himself slowly awaken into a confusing haze. He began to idly open his eyes but the moment the bright light hit his pupils he quickly shut them, the droning sound of the bulbs suddenly feeling as though it became ten times louder. The velociraptor winced as he felt his head pound and throb with a dull ache. He squirmed in place, soon realizing not long thereafter that something was holding him down.

RaptGenM forced his eyes back open, wincing again at the sudden unnatural brightness and flinching in place atop the table. He looked down toward his side to see his arm firmly locked against the table in a metallic clamp. He quickly turned his head to the other side of his body and found his other arm in the same predicament. An awkward shifting of his legs and the subsequent check that followed showed each of them to also be bound at the ankle, and as the dinosaur gazed down over his belly he noticed even his tail was locked in place by a heavy metal cuff tightly gripping the appendage and pinning it down.

A budding sense of panic quickly began to form in the raptor's mind as the realization that he was trapped sank in, though at the same time he also tried to figure out where he even was to begin with. The room he was in was full of cold reflective metal; bright objects hung over his body casting an impossibly white light and all around what little of the room he could see were computers, devices, and diodes so completely alien to RaptGenM that he didn't know the words to even begin to describe them. There wasn't a single place he'd ever been to that looked anything close to approaching this environment, he had nothing to compare it to.

Perhaps the most alarming realization though was that as the velociraptor struggled to make sense of how he ended up in this place... he couldn't even remember his own name.

The raptor's thoughts began to race at an ever increasing rate until the sudden sound of mechanical whirring instantly cut through the chaos and echoed around the room. RaptGenM's eyes darted everywhere he was able to see until from the corner of his vision a large metallic arm slowly swung in from the far side of the ceiling. The robotic appendage pivoted at its center unfolding much the same way a forearm would. The bottom half of the arm, past the central pivot point, contained a sizable hydraulic piston connected to a complex-looking geometric socket tip topped with a blunt white object. The arm shifted again, swaying in a full arc a couple of feet above the dinosaur until the end of its arm was pointing at his chest. It moved again at its central pivot, gradually aiming the end of the arm further down.

The room fell silent again for several moments until the sterile sounds of electronic movement filled the air as the arm began to move once more. Varby had taken control of it from the neighboring room after letting the device automatically deploy and calibrate itself, as a result its movement was now much slower and more deliberate. RaptGenM watched in a mixture of fear and curiosity as the arm came alive; the raptor was understandably tense as a result of being restrained, but at the same time he noticed the strange moving object wasn't sharp the way his toe claws were and as such didn't feel as though he was in immediate danger. The arm slowly crept forward, the end of it mere inches from his body. It realigned, moved again, and the very tip of its blunt object gently pressed against the dinosaur's tailhole.

RaptGenM's eyes widened in an instant. Instinctively, he tightly clenched his muscles to try and keep the probe on the end of the arm out of him, however the giant hydraulic ram it was connected to ensured that the device was going to go wherever its operator chose. The probe continued its forward movement forcefully spreading the dinosaur's tight ring open. A pained roar escaped RaptGenM's maw as his entire body tensed up in response to the slow invasion; he squirmed against the restraints of the table as the slick object inched further and further into him until more than a foot of it was buried inside his tight canal and the socket the probe was connected to was only a couple of inches away from his body. The raptor tried his best to calm himself as the probe finally came to a halt, but before the dinosaur could take in a deep breath to steady his nerves the arm once again sprung back to life.

The hydraulic piston hissed loudly as the probe pulled backwards nearly its full length before reversing direction and asserting itself again, easily pushing all the way back into RaptGenM now that his tailhole had a chance to acclimate to being spread open. The dinosaur growled and thrashed, but despite his feelings of displeasure he realized his body was starting to betray him. Never in RaptGenM's life had he allowed himself to be degraded in such a way, but at the same time he didn't entirely hate how it felt either. The dinosaur shifted awkwardly on the table, closing his eyes and arching his back slightly. He could feel his maleness quickly starting to swell within him and despite the raptor's best efforts to resist being aroused by what was happening his fully erect pointed cock slowly emerged from his sheath on its own anyways.

RaptGenM's cock throbbed weakly atop his belly, begging for attention as the probe nestled deep within his ass continued its methodical back and forth movements, each motion of the robotic arm punctuated by loud mechanical noise. After several deliberate passes by the probe RaptGenM felt it finally pull all the way out of him. In response he finally opened his eyes back up only to discover that the arm with the probe had at some point been joined by a second nearly identical arm with a different tip attached to it. The probe on the first arm, with the knowledge of hindsight, looked like nondescript male genitalia; the second one however had a similar shaft-like appearance to it but it thickened in the middle and more closely resembled an elongated egg than it did a featureless penis.

The second arm assumed the place that the first one had been in moments prior and, also like the first, slowly pushed itself forward. RaptGenM's used tailhole was able to easily take in the first little bit of the new probe, but it didn't take long for the dinosaur to shift uncomfortably as his muscular ring struggled to stretch open to accept more of the ovoid probe as its diameter gradually increased. The raptor winced again, his toes reflexively curling as a slight jolt of pain struck his body.

On the other end of the arm Varby could see on his control console a complete readout of information regarding RaptGenM, among them the measurements of his tailhole and the resistance the probe was experiencing. These two points of data were being graphed in real time and without even being in the same room as the velociraptor Varby was able to tell purely from the charts alone that the second probe was at its limit. He stopped the arm where it was, pulled it back just a bit to let his subject relax, and then began inching it forward again. The probe reached a negligible amount of depth deeper, something that happened a third time when the dragon repeated the process over again. Varby fully retracted the probe while tapping several other buttons on his console to initiate the boot sequence of the device that would mark the next stage of the experiment.

RaptGenM let out a sigh of relief as he felt the ovoid probe pull itself out of his body and watched as the arm pulled a significant distance away from him and parked beside the other one. His abused tailhole slowly closed up, a dull sensation of soreness washing over his sensitive orifice. The dinosaur tried to relax once again but the now familiar sounds of mechanical motion prevented him from getting comfortable. RaptGenM's eyes darted over to the pair of robotic arms but saw that neither of them were moving despite the noise persisting. He glanced around for several seconds until from the side of his vision opposite the arms a third device gradually came into view. It was another arm-like appendage except rather than be tipped with a slick white probe this one did have some kind of phallic tip to it but it was made of a highly polished metal. The metallic object was attached to a vented cylindrical barrel separated into three pieces by three large curved claws. Behind the arm's pivot point several thick flexible tubes ran down its length connecting the back of the barrel to something far out of sight.

While the first two probes didn't register to RaptGenM as dangerous, this one definitely did. The way the curved claw-like appendages resembled blades spoke to a deeper and more primal part of the dinosaur's mind that this thing was probably bad. The arm remained several feet away from him and after a few moments of silence a barely audible hum began to fill the surrounding area, the device being its source. The arm hissed loudly as a cloud of thick vapor poured out from behind its front barrel, its inner core filling with liquid nitrogen and the heavy mist evidence of its rapid evaporation. The vents on the sides of the chamber began to glow a very dull blue as the device was clearly gearing up to do something.

Past a certain point the sounds the arm was making stopped intensifying, plateauing at a steady electronic hum and the occasional hiss as its core continued to pump and recycle a constantly flowing chamber of coolant. From the control room Varby continued the arm's initialization process. A concentrated beam of red light in the shape of a set of crosshairs shined onto RaptGenM's body and from there the dragon slowly nudged and moved the arm until it was in a precise location. With the device on the end of the arm fully charged Varby made a couple of minor adjustments to its intensity, and hovered his scaly finger over the "ACTIVATE" button.

RaptGenM waited with bated breath to see what this new arm was going to do. Up to this point it was just making a lot of noise, but also glowing menacingly and constantly venting mist. From his orientation on the table though he couldn't see that there was a red sight being projected onto his lower body. Without any warning a sustained beam of energy fired from the metallic tip at the end of the arm's device straight at the raptor's tailhole. Before RaptGenM could react to anything he saw he threw his head backwards and let out a roar as the energy beam touched his body. He writhed against his restraints as a flurry of confusing sensations assaulted his intimate orifice. His tight ring was consumed by an intense rapidly pulsing warmth. Blended into that was the awkward sensation of slight numbness and gentle swelling. The feeling was its strongest right at his entrance but it bled deep into his lower body too. The raptor could feel his muscles twitch and throb and he hadn't the faintest clue if he was doing that himself or if something else was happening to him entirely. It wasn't painful, but at the same time it also did not feel pleasurable at all. RaptGenM gritted his teeth again, struggling to hold out having lost his sense of time almost immediately as soon as the laser hit him. Had the beam been focused on him for a second? A minute? He had no idea, he just wanted it to end.

Mercifully, the laser finally turned off. As quickly as the beam of warped light and energy appeared it vanished, its disabling signaled by a louder than normal hiss and a huge cloud of vapor venting from its backside. RaptGenM shifted on the table, the bizarre fire of sensations that had been consuming his most intimate of places already having practically vanished. The dinosaur groaned as he heard another bout of mechanical noise kick up, though his disdain was slightly diminished when he realized the sound he was hearing was the laser retracting backwards and slightly off to the side. From the other side of the operating room, where the other arms had parked, the first one reactivated and approached the raptor.

RaptGenM eyed the approaching arm noticing that at some point since its initial retreat it had apparently swapped probes, likely when the energy beam was in the process of warming up and distracting him with its noise and glowing blue lights. In place of the original phallic tip was a stout conical plug that widened all the way down its length. The velociraptor felt his heart start pounding in his chest; this third probe was very obviously larger than the egg-shaped one, and that one hurt.

He winced as he felt the slippery end of the probe brush against his tailhole, bracing for the worst. The sound of robotic droning echoed throughout the room once more as the conical probe followed the same process as the two before it and pressed against his ring. RaptGenM shifted on the table, flexing and curling his toes as the familiar sensation of his tailhole slowly stretching open to accommodate the invading instrument lit up his senses.

The cone probe near effortlessly opened RaptGenM up to the point where the ovoid one had to stop, Varby noting as much from his position in the control room and suspending it there intentionally. After a brief pause he resumed steering the probe, easing it ever so slightly forward while watching the readout on the console. A grin slowly spread across the dragon's face as he watched the data stream for RaptGenM's diameter gradually surpass where it had previously capped... and kept going. Unwilling to rush matters, Varby eased off on the probe's uniform advancement and dialed it back a bit choosing to instead inch it further into the raptor in a loose one-step-backward-two-steps-forward pattern to avoid causing too much discomfort. Eventually Varby reached a point where he had no choice but to stop the probe a second time, not because the graph mapping diameter to resistance was spiking into the red zone again but because the entire probe save for perhaps the last half of an inch was buried inside of the test subject.

RaptGenM sucked in a deep breath through his teeth as he felt the slick probe slide into him. The smooth plug easily spread him open, reaching the width that was painful last time though the velociraptor found himself experiencing no discomfort whatsoever. In fact, in defiance of what he wanted to admit to himself, the sensation actually felt quite enjoyable. Unknown to RaptGenM the beam of energy that had been directed at his tailhole was part of an experimental cellular enhancement array. Not only had the device made his ring substantially more pliable, it had also multiplied and enhanced the nerve endings in and around his orifice turning what was already a sensitive part of the dinosaur's body into an incredibly erogenous zone. The warmth that RaptGenM had felt was the energy beam's influence penetrating his male cavity, plumping up his puckered ring and increasing his inner elasticity and depth.

Right now, he was feeling the combined effects of all of those things at the same time. RaptGenM vocalized a pleasured rumble as he felt the cone probe alternate between stepping back and inching further forward. Though he couldn't see it he could tell his tailhole was yawning open impossibly wide; he could feel how massive the circumference of the probe inside of him had become simply by clenching up around it and each time he did so a rush of intense sexual pleasure washed over him. His erect maleness throbbed wantingly, still begging for attention. He didn't want the probe to stop, he wanted it to keep spreading him open further and further, pushing increasingly deeper. However, much to RaptGenM's dismay the probe did eventually come to a stop once he'd fully hilted the entire thing. As the plug began to slowly pull back the dinosaur grumbled, he tried to clench around it again but due to the shape of the probe and how slippery it was he wasn't able to get any meaningful purchase on it.

His disappointment didn't last long though, as the cone probe fully withdrew itself the other arm with the egg-shaped probe quickly took its place. RaptGenM eagerly welcomed the second probe, grinning pleasurably as he felt the elongated ovoid press against his loosened tailhole and easily slip into him. The familiar egg shape spread the dinosaur open, and now that he was able to stretch beyond its widest point it was able to keep going. As the egg pushed deeper into RaptGenM he moaned as he felt his tailhole start to close back up around its other end, holding the entire thing inside of him. Unlike the cone probe, which felt good purely from the standpoint of being stretched wide, this one filled the velociraptor with an satisfying feeling of fullness. As the probe inched itself back and forth inside of him he tightly clenched around it, relishing in the sensation of the device teasing parts of his body he didn't even know he had.

RaptGenM's eyes slowly lidded, the dinosaur relaxing to the point his body was nearly limp as he rumbled lovingly. For several moments he savored the feeling of his inner cavity enveloping the bulbous probe until with one long steady stroke it slowly withdrew itself from his body. The raptor let out a mixture of a satisfied sigh and murr, but a familiar humming sound soon brought him out of his relaxed state. If the steady electronic hum wasn't enough of an indicator of what was happening the low hissing of misty discharge certainly was, the beam was once again warming back up.

The velociraptor watched as the beam arm shifted back into the same place it'd been earlier, the inside of its front chamber with the strange claw-like brackets on it glowing a steady blue again. He looked the gun over several times wondering what it could possibly do next, fire upon him a second time and then introduce an even bigger probe? The gun's pitch adjusted itself ever so slightly as Varby took control via his console's manual override, and then when he was sure the projected crosshairs were where he wanted them... activated the laser once more.

Another concentrated beam of energy blasted from the gun in a fraction of a second, the faintly red and blue laser seeming to twist and bend the light around it. As soon as it struck RaptGenM the dinosaur immediately shuddered as the indescribable sensation of his flesh shifting and changing instantly overwhelmed him, except rather than hitting him on his tailhole this time it struck several inches further up. The velociraptor cried out as he felt his entire sack and, more alarmingly, its contents become consumed in an intense churning warmth. RaptGenM gritted his teeth and exhaled a sharp pained breath as each of his balls throbbed with nearly the same intensity as his heart in long rhythmic pulses. Through the haze of heat and the intense feeling of pins and needles he could feel them aggressively swelling as their cells began splitting and multiplying at impossible rates. His toes curled. His hands trembled as his fingers stretched out. The dinosaur's entire body shook as he felt himself on the verge of falling unconscious, but just as RaptGenM's vision began to cloud over the beam finally disengaged.

A large cloud of vapor vented out from the back of the gun. Its low hum threateningly hung heavily in the air. RaptGenM sucked in several deep breaths as he tried to steady himself.

And then the gun fired a second time.

It had been adjusted just a couple of degrees again, the beam now striking the velociraptor right in the middle of his erect cock. The same tidal wave of sensory overload consumed RaptGenM's mind as he felt the same indescribable sensations envelop his maleness. His body tensed up in response to the initial hit and as it passed he began to thrash around in his restraints. He craned his head down as far as he could and forced his eyes open, staring at his shaft and watching as it shifted and contorted. The raptor let out a hoarse moan as he witnessed his body changing before his very eyes, not just seeing his cock throb and grow but feeling every second of it too. He shuddered as an intense tightness almost painfully took hold of his maleness, a persistent claustrophobic feeling that seemed to have no end. RaptGenM watched out of a mix of fear and amazement as his cock swelled and firmed up just like it was when it was becoming erect, except it was already erect to start with and instead was just slowly continuing to grow even larger.

The beam once again finally turned off letting the velociraptor collapse backward against the table and begin trying to catch his breath again. The bizarre instant on/off nature of the beam, going from complete overload to nothing at all in an instant, frazzled his thoughts and left him mentally exhausted. Several moments passed after which RaptGenM felt like he'd calmed down considerably. He glanced back down at his crotch again, now able to finally make sense of what he was seeing and take it all in. His mouth hung slightly agape as he realized his cock was now easily twice as big as it was before, and he was already quite proud of his endowment to start with. Despite being restrained and not able to get as good of a look as he wanted he could also see how large his balls had become. More importantly though, he could feel them. His two ovoids rested heavily against his body, the tops of the curves they made in his sack just visible behind his swollen cock. Though he couldn't see them, they too had similarly doubled in size.

Through all of this though, the relentless humming of the glowing energy gun never stopped. In the control room, Varby was hastily shuffling through some files on his terminal eager to see just how much he could get away with during his current experiment. The gun fired again, targeting RaptGenM's sack a second time and taking the dinosaur completely by surprise. He reflexively let out a shocked roar as he felt his abused balls instantly start churning and throbbing - and growing - again.

In Varby's excited haste though, he jerked his arm back toward his control console a little too quickly and in the process knocked over his mug of tea. Several ounces' worth of hot liquid poured across the dragon's console causing its touchscreen to immediately short out and begin registering erroneous contact points all over. The scientist began hurriedly trying to navigate the menu on the screen quickly growing frustrated with the fact that his console was acting as if whatever it was he was trying to touch was several inches off in another direction. As he fought to regain control of the console, its energy beam was now a runaway device.

As soon as Varby's tea splashed across the screen the beam immediately disengaged, but it did not shut down. The arm it was connected to began to contort and adjust its pitch and yoke seemingly on its own for several moments as the dragon found himself in a losing battle of control. RaptGenM was aware of none of this however, to him the arm was shifting and swaying around pointing its tip all over the place. Just as the laser gun came to a halt as Varby managed to wrangle it, it activated again seemingly on its own. With its alignment thrown completely out of whack the beam's "target" wound up being the dinosaur's head and as it fired its beam the concentrated stream of DNA-altering energy penetrated straight through RaptGenM's skull into his brain.

The velociraptor instantly fell limp as all of his mental faculties blanked completely. Despite what should've likely been another bout of familiar tingling warmth the dinosaur was too stunned to detect any stimuli whatsoever. The energy gun's beam was sustained on him for several moments until Varby was able to yank the gun sideways. As the laser arm twisted itself far past its safe range of motion the long rubber tubes feeding it liquid nitrogen severed causing the machine to vent all of its coolant in a matter of seconds. The arm groaned as its upper hydraulic ram extended far enough to cause its mounting bracket to separate, dropping the energy gun onto the floor with a loud crash and a flash of electric sparks as its power conduit immediately failed under the weight of the falling device.

The resulting power surge caused by the energy gun's rapid disassembly overloaded the circuitry of the laboratory cutting power to everything except for emergency services. This resulted in the cuffs of the examination table disengaging, freeing the dazed raptor.

RaptGenM shifted awkwardly atop the table, his eyelids fluttering as his eyes gradually corrected themselves from having rolled backward into his head. He felt drunk, as if everything around him were happening in slow motion. His eyes slowly scanned the room he was in, now awash in dim red emergency lighting. He rose up into a seated position as his memory, recently at least, began to come back to him. He had been trapped, but now he was able to move again. As he was piecing these fragments together a sustained hissing sound pierced the room and seconds later visible clouds of green gas began to pour out from several metal vents that lined the lower perimeter of the room. RaptGenM realized he'd been trapped and now he was able to move, and now he definitely needed to get out of the room he was in.

Directly in front of him was a giant mirror, the one-way panel that Varby had been using to observe the experiment. RaptGenM lunged at the window, the force of his entire body hitting it causing several cracks to appear. Varby stumbled backwards in response, banking on the poison gas that was slowly filling the room to take effect before his test subject could cause any further damage or even worse, breach containment. RaptGenM threw himself at the window a second time, further weakening it this time with very audible crackling noises. The scientist held his breath as he watched the velociraptor's body slump downward. He realized that even if the gas managed to subdue the dinosaur that the integrity of the control room was too compromised to be considered safe and the fumes would easily seep into there as well. He reached forward to try and eject the data disk from his console but in his nervous haste missed the tiny eject button several times. As he pocketed the diskette RaptGenM had managed to get back onto his feet and with the very last of his energy heaved himself at the wall for all he had, and this time the entire reflective panel gave way and shattered into a flurry of giant shards.

Varby was already one step out the door as the velociraptor crashed into the control room. Despite the shards of broken glass tumbling across the floor cluttering his view the dinosaur still spotted the fleeing dragon and immediately gave chase, slipping past the mechanical door just as it was about to close.

Varby paused for a moment, catching himself on one of the structural beams lining the laboratory halls to take several deep breaths. Sensing movement out of the corner of his eyes, the dragon quickly turned his head upward to see what it was. Stalking Varby with the quiet pursuit his kind was known for, RaptGenM was a handful of yards away. A sharp jolt of anxiety shot down Varby's spine and the dragon's eyes widened briefly in time with the nervous gasp he involuntarily vocalized. Realizing he was irrefutably in imminent danger, the scientist hastily fled further down the hall in a rush to make it to the security door at its far end.

RaptGenM gave chase, keeping up with Varby while maintaining enough of a distance to react to any sudden attacks or retaliation. He still didn't know who the dragon was, only that he was in the room he'd barged into when clearing the plate glass mirror. Given that the dragon was clearly fleeing from him, RaptGenM assumed he might have something to do with the predicament he'd awoken to prior. The velociraptor slowly closed in on Varby as he believed he'd backed the dragon into a corner.

Instead, Varby was nervously hammering on the security keypad next to to the door in front of him. As the dinosaur crept ever closer to the dragon he started hearing a series of peculiar electronic tones. RaptGenM ducked over toward the far side of the wall hiding most of his body behind a support beam. His mind raced with all the different ways he could spring his attack, too on edge to notice that he was now somehow envisioning several plots all at the same time as opposed to doing them individually like he used to. A grin slowly spread across the velociraptor's face as he settled on a plan; he silently ducked across the hall to the other side, corralling himself behind a different beam, but just as he was stepping out to line up his leap he stopped dead in his tracks as the sudden noise of the heavy iron doors opening caught him off guard. Varby's unknowingly well timed activation of the entrance was the only thing that allowed him to scrape by with a near miss a second time.

By the time RaptGenM registered that the dragon he was pursuing wasn't cornered after all it was too late for him to spring his surprise lunge. The dinosaur grumbled to himself as his rush landed him right in front of the door just in time to have it close in his face. He eyed the door over for several moments, knowing that the thing currently blocking his path does move and in order to make it move you had to do something to it. His attention gravitated toward the illuminated panel beside it. The raptor leaned forward to get a better look at it, seeing each of the little squares on it adorned with a symbol he didn't recognize. Experimentally, he prodded one of them with his finger perking his head up slightly as the keypad emitted a dull tone. He pressed another, hearing a slightly different tone.

The dinosaur's eyes squinted slightly as he began thinking about the tones. The keypad had made a similar assortment of noises just before the door opened and let Varby through. RaptGenM rationalized that in order to get the door to open he had to get the box in front of him to make the same noise. Despite his newly augmented intelligence being at odds with not understanding the symbols on the keypad, his assessment was close enough to still be correct. RaptGenM touched each of the different buttons making sure to commit to memory how each of them sounded. Once he'd put together a mental note of the keypad's makeshift musical scale, he began to click the buttons in an order close to what Varby had done. When the door didn't open, RaptGenM tried again and fine-tuned the "melody" he was playing. After only a couple more tries, the light at the top of the keypad turned a steady bright green and the familiar mechanical sound of the door's inner hydraulic rams activating filled the hallway.

On the other side of the door Varby had hastily stumbled his way across the communal mess hall to sit down on a set of small stairs that led up to an elevated dining area. The dragon let out a pained sigh of relief as he watched the door close behind him and lock the velociraptor on the other side; he'd notify the laboratory's administration of the accident in a moment, just as soon as he could finally catch his breath. Varby closed his eyes and leaned backwards against the wall and held that position for several moments until his focus was disturbed by the sound of the mess hall door activating. He quickly glanced up at the door to see RaptGenM standing in the archway.

Varby was stunned. There was absolutely no way the dinosaur should've been able to open the door, he was certain of it. The impossibility of the matter was of no concern however as it was apparently anything but. Another pang of adrenaline hit Varby's gut and in an instant he tried to get up to flee yet again, though in his haste he immediately backed into and stumbled over one of the potted plants that capped either side of the stairs he was sitting on. As the dragon fell over the plant he landed ungracefully, hard enough for the glasses he was wearing to slip off of his head and land a couple of feet away. A sense of panic had already been coursing through the dragon's body since the door opened, but now that feeling was all-encompassing. He was prone on the tile floor, his glasses thrown far enough away that he couldn't see them. He was as good as dead; he was sure of it.

A knowing grin spread across RaptGenM's face as he watched the dragon stumble backwards and begin floundering on the ground. Battle plan or not this was his time to strike and he wasn't going to let that opportunity slip by a second time.

The velociraptor closed the distance between the two reptiles by lunging across the floor, wrapping his arms around Varby's tail and digging his claws in hard enough to break the dragon's scaly skin. Varby wailed in response, thrashing the end of his tail side to side as he fought to break free of RaptGenM's grip but it only served to drive the dinosaur to tighten his talons.

Somewhere between breaking out of the examination room and pursuing Varby into the mess hall RaptGenM had lost track of the fact that the strange beam of light that struck him had induced some very specific, but significant, changes to his body. RaptGenM smiled to himself as thoughts of feasting on the struggling dragon's flesh danced across his mind, though as the two reptiles fought and struggled on the floor their bodies constantly bumped and rubbed against each other. As RaptGenM leaned forward to move his claws toward Varby's neck the sensation of his crotch inadvertently pressing against the dragon's hindquarters in such an awkward and compromising position reminded him of those changes. The velociraptor's vicious attack paused. A different kind of urge that needed to be sated quickly came to the forefront of the dinosaur's consciousness instead.

RaptGenM flexed his pelvic muscles and glanced down, watching as his semi-erect cock emerged from its sheath. With the dinosaur's mind already clouded with lustful thoughts it didn't take long for his maleness to quickly reach full mast. He'd seen it once already like this in the examination room shortly before the laser gun malfunctioned, but now that RaptGenM was free of the operating table's shackles and free to move around he also had the freedom to appreciate the sight of his altered cock. It was massive now, not just twice as long but also very obviously twice as thick too. The velociraptor could almost feel his own pulse in his shaft if he focused on it hard enough on account of its vasculature also growing in size, and hanging heavily underneath his sheath he felt his two plump balls wrapped tightly in his scaly sack.

As the dinosaur took in the sight of his impressive maleness he noticed just inches away from it was Varby's tailhole, the faintest little bit of pink visible at the center of the dragon's wrinkly creamy peach-colored skin on account of his body being splayed out and his tail yanked upward. The desire to breed quickly overrode RaptGenM's desire to feed and the velociraptor shifted himself on the floor in such a way as to press the dull pointed tip of his cock against the dragon's entrance.

Varby shuddered. A wave of goosebumps-like tingles crept across his spine in a split second as he felt the dinosaur's shaft brush against his tailhole. He wasn't dealing with the grotesque pain of feeling his test subject's razor sharp claws ripping his throat out, which Varby definitely understood was a very good thing, but in its place was something else entirely that the scientist was just as panicked about. He felt the raptor's body shift, the dinosaur's cock pressing harder against his pucker as he found better footing on the floor. RaptGenM pushed forward as he continued to yank Varby's tail into a submissive position, the precum-slickened head of his cock gradually inching forward into the dragon until his resistance completely failed.

An involuntary shriek escaped Varby's maw as against his efforts he felt the slight ridge of the head of RaptGenM's cock push beyond his tight ring. The dragon's tailhole struggled to stretch to accommodate the augmented velociraptor but as soon as the ridge made it in almost the entire shaft followed as RaptGenM eagerly buried himself as deep into Varby as he could in a single stroke. The end of the dragon's shriek was punctuated by an sudden hiss of pleasure as RaptGenM savored the feeling of the dragon's soft inner walls quickly covering his shaft in an intense warmth.

RaptGenM repositioned himself again, pulling his hips back a bit in the process before thrusting forward once more. The yellow skin of the velociraptor's underside pressed against Varby's peach skin as he fully buried himself inside the dragon on his second push. RaptGenM vocalized another pleasurable sound, a low rumble this time, as he held himself in place for just a moment feeling his large cock gently throb inside the scientist's tight canal. The dinosaur withdrew himself slightly only to push himself back in as he began a slow but deliberate pace of penetrating the dragon. With every pass RaptGenM made he could feel his swollen balls sway and move, their presence apparent now more than they ever were before.

Although he hadn't been dismembered, Varby still desperately wanted to get away from RaptGenM. The dragon squirmed and fought against the dinosaur's grip, his legs twisting at awkward angles trying to get whatever purchase he could on the slick tiles. He tensed up as he felt the dinosaur thrust into him, the sudden feeling of being completely filled in such a deeply intimate manner sending a mixture of conflicting sensations through his body. Varby gasped, sucking in a breath as he waved his arms around in front of him to try and find something he could grab, glasses or otherwise. He gasped again on RaptGenM's next thrust, though his vocalization turned into something of a surprised grunt as he felt the raptor's heavy swollen sack slap against his normal, unaltered one.

Varby was no stranger to experimentation, both as his profession and also with his pleasurable pursuits; he'd had some limited experiences with others, but never something as intense as this, and never with a test subject. He'd also never been with a dinosaur before, at least not a carnivore, due to how unpredictable and violent they could be. Had it not been for a combination of Varby's prior experiment and the uncomfortable way that he'd tumbled onto the floor putting RaptGenM in an aroused state he was certain his guts would be all over the mess hall and partially inside the raptor's stomach too. A lot of dominoes had to fall in a very specific way, something Varby was gradually starting to realize as the threat of imminent death was slowly replaced with a shameful kind of pleasure.

RaptGenM continued his eager thrusting inside of Varby's tight rump, but the dragon's ever-swaying tail constantly bopping the raptor in the face as he struggled to claw himself away was starting to become annoying. The dinosaur yanked Varby's tail to one side prompting the scientist to yelp in pain as he felt the kink in his tail register all the way up his spine. He tried to fight RaptGenM's manhandling of his body, realizing that if he were on his back he'd be even more vulnerable than he was right now, but even as the slightly bigger of the two Varby was still no match for the physical brute of a creature built to be an apex predator. The dragon let out a terrified whimper as he felt himself be overpowered and tossed belly up.

Getting tossed onto his back was it, this velociraptor was going to have his way with him in several manners. Varby was absolutely certain. Any moment now he'd feel the sudden pang of teeth or a claw break the skin of his neck and it would all be over in a matter of seconds.

But that life-ending rending of flesh never happened. Varby rolling onto his back prompted RaptGenM to shift his position once again; the velociraptor now towered over him as he continued to rhythmically plunge his cock deep into the dragon, his hefty balls now audibly hitting the underside of the base of the scientist's tail on almost every pass. The otherwise silent mess hall was filled with the sounds of saurian sex as RaptGenM relished in Varby's tightness. Varby shifted himself against the floor, craning his neck up to try and see in front of him but his field of view was a nondescript fuzzy brown and yellow blob on a background of indiscernible shades of gray. He knew it was RaptGenM he was looking at, he just couldn't make anything out.

The concept of things like eyeglasses was foreign to RaptGenM. He was unaware that despite making eye contact with Varby the dragon couldn't actually see him, but to the dinosaur he found it much more alluring to be able to see the scientist's reaction to being taken in such a way. As Varby's head slowly craned back down RaptGenM's gaze trailed downward, focusing on the sight of his thick saurian cock working itself into and out of Varby's tailhole. The dragon was wrapped so tightly around his length that as RaptGenM pulled back he watched as the stretched out ring of his intimate hole visibly clung to his cock just a little bit. The sight only served to arouse the dinosaur even further and in response his next several thrusts came with noticeably more muscle behind them.

What was also apparent to RaptGenM however was that Varby was starting to enjoy being stretched and filled so completely. The dragon's own cock gradually inched out from his sheath as it swelled and plumped up into an impressive size, smaller than RaptGenM's following the experiment but still generously sized for someone of Varby's stature. RaptGenM teasingly caressed the scientist's shaft, watching as the organ flexed in response and the dragon vocalized a soft but still audible moan. The velociraptor grinned as he wrapped his fingers around the maleness presented to him, running his scaly hand along the dragon's length as he explored its unique shape. It had a thick body overall and even in its fully erect state there was a noticeable fleshiness to it, but its most apparent difference from the raptor's was at its head; Varby's cock had a slight point but it was flattened somewhat, and the ridge behind the head was similar but had several barely noticeable ridges around its circumference. RaptGenM hadn't seen anything like it before but he could tell just from what little he'd touched that Varby was certainly enjoying it if the rapidly swelling bead of pre at its tip was any indicator.

Varby stirred, moaning lightly as he felt RaptGenM wrap his fingers around his cock and start stroking it. The constant flip-flopping between pangs of adrenaline over fear of mortal injury and jolts of pleasure from having his cock fondled and his tailhole spread out and filled was wreaking havoc on the dragon's mental state, not to mention the sense of shame and humiliation that came with being rendered so compromised and taken advantage of by a test subject no less. Despite this the dragon could feel his release rapidly building up inside of him; his thick dragonhood slowly drooled a steady stream of thick clear precum that RaptGenM was eager to spread across the scientist's sensitive flesh with every pump of his hand.

Varby arched his head back from from his defeated position once more to try and look at the velociraptor, but again was just met with a blurry mess of hues. He gritted his teeth slightly and let out a pleasured roar as he reached his climax. The dragon's cock throbbed in RaptGenM's grip, each one releasing a thick rope of milky white seed. As the dinosaur felt the shaft in his hand start to pulse and throb he looked down at it, his maw slightly agape as he watched the slight bumps around the head of the dragon's cock flare out into prominent fleshy spines. He experimentally ran his hand along them while continuing to stroke Varby off through his climax and grinned to himself as the dragon squirmed in response, the mere touching of the spines being nearly too much to process while in the throes of orgasm.

As Varby rode out his climax every pulse of his cock was matched with an intense tightening of his tailhole. Each time it happened it induced a milking sensation in RaptGenM's shaft and the raptor was only able to make a couple more passes before the dragon's rhythmic clenching quickly brought him to his breaking point too. RaptGenM let out a sustained low growl of pleasure as he felt his enhanced cock join Varby's in dispensing their bodies' sexual payloads. The velociraptor's balls clenched tightly against his underside, every pulse of the dinosaur's cock releasing almost as much cum in each shot as he used to in an entire climax. RaptGenM's eyes lidded slightly as he grinded his crotch against Varby, his cock buried all the way inside the dragon as his orgasm lasted much longer than he could ever recall practically pouring several loads worth of dinosaur seed deep into him.

Each time Varby's tailhole tightly clenched around RaptGenM's large shaft it sent a zap of pleasure through the dragon's body, and the times where the reptiles' throbs matched up with each other felt even more intense. Varby moaned as his hand made its way to his lower belly. He swore he could feel the slight warmth of the massive load of seed pumped into him by the dinosaur barely radiating outside of the walls of his intimate canal and into the area around it. It was a feeling he hadn't experienced since the last time he and a colleague had fooled around with a batch of inert slime; he remembered just how much of the stuff he had to fill himself with before he started to feel it much in the same way and the mental image of RaptGenM pumping that much seed, not goop, into him scratched the same deeply erotic itch.

Varby shuddered as the sudden spike of arousal struck him like a bolt of lightning. The dragon trembled and let out a staggered moan as in an instant he reached orgasm a second time almost immediately after his first release had tapered off. His swollen dragonhood, still flared from his first climax, came alive again pulsing and twitching in quick contractions releasing several more pumps of seed onto the tile floor joining the sizable puddle already there. Hitting his climax twice in quick succession combined with the feeling of RaptGenM's hand still stroking and teasing his flared cock had the scientist in a daze; his senses were overloaded to the point that his vision would've defocused even if he were still wearing glasses. The swirling storm of panic, pleasure, and exhaustion the scientist was feeling finally became too much to bear and with a final prolonged rurring sound Varby collapsed backward onto the floor, unconscious.

RaptGenM smiled deviously to himself as he watched the dragon before him writhe in pleasure. He took in a sense of twisted pride in the fact that it was the massive tool between his legs that had reduced Varby to a squirming mess of incoherent sounds that had not only just cum twice back-to-back, but also passed out entirely. Fantasies of doing the exact same thing to other velociraptors quickly filled the void in his mind that minutes prior had been occupied by mounting and unloading into the dazed dragon laying on the ground. The raptor took a step back and slowly withdrew his semi-erect shaft from Varby, watching as inch after inch of his maleness pulled out from the dragon's soft depths until finally the slight crown around its head popped loose. The dragon's well-used tailhole stayed just slightly agape as it slowly closed up, not a single drop of dinosaur cum to be seen.

RaptGenM took a moment to admire his handiwork before the inklings of becoming a pack alpha once again became too loud to ignore. He realized that before he could lay claim to countless other raptors though he'd first have to get out of whatever this place was that he was currently in. The floors were hard and cold, the light unnatural. The only foliage around were plants sitting in round metal containers. It was a world completely alien to the one RaptGenM had spent the entirety of his life in up to that point, but he knew that if he had somehow been brought to this place that meant there was at least one way out of it. He just had to find it.

The velociraptor glanced back down at Varby a final time before turning away and leaving back through the door he'd entered.

As RaptGenM retraced his steps he paid more attention to his surroundings. He didn't recognize what kind of "dinosaur" Varby was so he had no frame of reference or past experience to compare him to; as a velociraptor he hunted in a pack, there was the potential for whatever Varby was to do the same. Perhaps his mates would not be as cowardly, either. RaptGenM understood that he was out of his element as long as he was confined by the metallic walls currently surrounding him and finding a way back to the jungle was of the utmost importance. He passed by a floor plan of the facility and glanced at it for a moment, though because it was covered in unfamiliar symbols he knew not what the diagram was showing.

A familiar door just ahead led to the examination room RaptGenM had awoken in, the raptor remembered the vantage point he had as he rushed out of the door earlier and peered down the hallway at Varby. There was no reason to go back in there, both because he already knew there was not an exit and also because he remembered the room filling with a very pungent knock-out gas. But the door after it further down the hallway? That was fair game. The velociraptor approached the laboratory door and eyed the keypad next to it. Like everything else in this place it was covered in glyphs he didn't understand, but it did look exactly like the ones on the pad beside the mess hall. The dinosaur paused for a moment as he recalled the series of tones that opened the other door, his enhanced brain having dutifully committed it to memory. The sound of clacking dinosaur claws interspersed a series of electronic tones as RaptGenM repeated the scale. The LED on the keypad illuminated bright green signaling that a valid code had been entered. The metal door groaned as it slowly slid aside on its hearty track, and the velociraptor invited himself inside.

Just past the door was another small control room almost identical to the one that was on the other side of the glass he'd smashed through. This one also had one-way mirrors installed in it letting RaptGenM look into the neighboring examination room, but not the other way around. It too was almost identical to the one he'd already seen when he was strapped to the table, but just before he turned to leave the room something caught his eye: a door. Inside the examination room was another door, something that was missing from the one he'd been in. Another door meant another possibility in finding a way out, so as to leave no stone unturned RaptGenM made his way through the control room and into the larger examination area.

By all accounts this second examination room was just a copy of the other one, the same kinds of computers and equipment completely foreign to the velociraptor dotted the walls. There was also an operating table in this one too, though it was one of the things in this room that differed from the other; the one RaptGenM had awoken to find himself shackled to was mounted firmly to the floor beneath it, this one however looked the same but was attached to a long sliding track the end of which was at the foot of the door that had caught the dinosaur's attention. In a very broad way, he understood that this was a path of some sort.

As RaptGenM navigated the examination room his focused shifted from the door on the far side of it to all of the puddles and splatters of an unknown bright green substance that peppered the floor. It was everywhere, but it was especially focused around the empty examination table, the track leading up to the door, and the door itself. The dinosaur eyed it cautiously, intentionally stepping around it as he crossed the room. The door that served as the raptor's waypoint was not as ornate as the others he'd seen, absent were the bright yellow and black hazard stripes and strip of lights surrounding its edge; it was just a plain steel door. There was a sign above this one like all the others however, though also like all the others RaptGenM wasn't able to understand what it said so it was of little use. Underneath the smear of green ooze that had managed to splatter across half of it the sign read "Danger - No Exit", a warning that ultimately would've fallen on deaf ears even if it had been visible.

Another numerical pad was attached to the wall beside this door and a pair of large glass tanks filled with more green liquid capped off its other side. Unlike the other security devices this one had a lot less buttons on it, only two. RaptGenM looked his options over, a solid square and an outline of a square. Piecing together that the symbols were perhaps a representation of a closed and an open door the velociraptor tapped his claw on the outlined shape first. The dinosaur jumped back, startled, as the door hissed loudly and vented a visible white vapor as its two massive hydraulic locks disengaged and allowed the door to retract backwards and off to the side. He was correct. A thin cloud of mist poured out from the bottom edge of the open doorway, spreading across the floor like a liquid, but as the raptor peered into the room all he saw was pitch black.

Curiously, RaptGenM leaned further forward, the tip of his snout crossing into the darkness. The air around him was heavy with the scent of vegetation and an inexplicable sterile sting that the dinosaur had no knowledge of: rubber. The examination room had the faintest traces of the blended scent to start with, but opening the door intensified it seemingly exponentially. The smell of "the outside" is what caught the raptor's attention though, and was why he experimentally leaned forward a little more to try and scout what was through the doorway. He figured even if it was the middle of the night if this door did lead to the outside world he'd at least be able to see the landscape in the familiar purple cloak of natural darkness. There was nothing. This wasn't the way out, he determined.

RaptGenM turned to leave and after taking a couple of steps he paused as the sound of mechanical humming consumed the room. He didn't realize it, but opening the door that he wrongly assumed was an exit also triggered the skylights in the room that door led into to also open, the process just took several more moments to start as the hydraulic structure quietly primed itself after first disengaging the door locks. The whirring sound of opening grates lasted only a handful of seconds before it was replaced by the ambient sounds of what could only be described as "wet movement". The sound of several snakes crossing over and under each other. Footsteps in a marsh. Water shifting inside a cave.

The raptor froze in place. The noises sounded almost natural, but not quite. He slowly turned the upper half of his body to the side, glancing over his shoulder at the open door. The room beyond was now fully illuminated, and inside of it he could see a writhing mass of shimmering black snake-like appendages. The ends of the serpentine lengths were each crowned with a tapered green tip just as shiny and wet as everything past it. The tentacles shifted and swayed as the sunlight filtering into their room gradually aroused them from their dormant state. RaptGenM swore one of the appendages "looked" at him with its pointed green "head" and regardless of whether or not that was actually the case or his mind was just playing tricks on him the velociraptor identified the potential threat nonetheless and immediately turned around to make a mad dash to the door leading to the control room.

Unfortunately for RaptGenM though, he made it less than a single step. A pair of black tentacles almost as thick around as the dinosaur's tail lanced out of the neighboring greenhouse too fast for even the cagiest of creatures to react. One of them hooked itself around the raptor's left leg and yanked it backwards causing him to stumble while the other one dove underneath his thrashing tail, between his legs, and up around his midsection to grab hold of RaptGenM's center mass. The velociraptor let out a loud shriek as he immediately began tugging against the pull of the vines but as he struggled to pull his ensnared leg forward the slippery tentacle tightly wrapped around it pulled in the opposite direction twice as hard. Barely a second later a third vine joined the first two coiling around RaptGenM's neck further adding to the unrelenting force pulling him toward the doorway and crushing his throat at the same time.

The velociraptor sputtered as he tried to suck in a breath of air but the tentacle wrapped around his upper body restricted airflow to a mere trickle. Every synapse in RaptGenM's brain was telling him to get out at any cost but the strength of the serpentine coils was a battle he was doomed to lose. A shrill screeching sound reverberated around the room as the raptor's large toe claws scraped against the metal grates underneath him, slowly but surely the vines were winning and reeling him in further and further toward the door. As RaptGenM's tail crossed through the entryway he felt several more smaller tendrils grab hold of it and assist the larger vines. Seconds later, he was completely inside the greenhouse.

As RaptGenM was pulled into the neighboring area he became immediately disoriented by a myriad of vines roughly heaving his body through the air. The tentacles suspended the dinosaur above what could only be described as a pit of snakes, except instead of dozens of writhing reptiles it was instead a mass of shifting slimy black tentacles of varying sizes. The sprawling mass almost completely filled out the floor of the room, assuming there even was a floor beneath them; around the edges a waterline was barely visible, suggesting that the creature was either water-dwelling or being grown hydroponically. Truthfully, there was no way to tell.

None of this mattered to RaptGenM though as even in his current state of being suspended in the air upside-down and inside of a haphazard pseudo-cocoon of tentacles he still fought against anything they tried to do to him. A loose tentacle with a thickness somewhere in the middle of the pit's range, about as thick around as RaptGenM's arms, snaked it way through the air and held itself a few inches away from the tip of his snout. Its green tip pointed itself at the dinosaur for several seconds almost as if it were "looking" at him in some strange way just like the first couple that had pulled him in, then inched forward and nudged the raptor's face. RaptGenM winced and quickly jerked his head to one side and then the other as the vines entangling his body tried to push him back straight ahead.

The tentacle that had been probing the dinosaur's face remained where it was, swaying just enough for its movement to register in an almost mocking manner. A much smaller tentacle wound its way up from the mass and along RaptGenM's face until it reached the very corner of his mouth where his rows of teeth ended and the primary joint of his jaw began. The tendril easily slipped itself into the pocket formed by the raptor's cheek and darted across his maw in an attempt to exit from the same pocket on the other side. Reaching it, the black tendril wrapped itself around the dinosaur's lower jaw and with a surprising amount of unexpected force slowly pulled his mouth open.

Sensing that the path ahead was clear, the larger tentacle lanced forward burying itself in RaptGenM's mouth. The trapped dinosaur gagged, an overwhelming blend of rubber and vegetation coating his entire tongue as the slippery tentacle slid across the organ and began penetrating his throat. The velociraptor sputtered audibly as he quickly tried to tighten his gullet to prevent the invading appendage from going any further but its bitter-tasting slimy coating easily defeated the slick walls of RaptGenM's inner flesh. He convulsed slightly, his eyes rolling back just a bit as he felt the tentacle continue forward down his throat stretching out every inch of it along the way. The raptor squirmed at the discomfort, sucking in a strained breath through his nostrils as he tried to adjust to the near permanent sensation of being on the verge of choking.

The sudden feeling of something brushing against his cock was enough to break the daze that RaptGenM had unwittingly fallen into. He was oblivious to the fact that he was even aroused in the first place given what was happening with the tentacle in his mouth, but unknown to him the slimy film coating all of the tentacles that had ensnared his body was a powerful synthetic aphrodisiac; just touching the vines was enough for the slime to have a minor effect, but swallowing it by way of the one lodged in his maw introduced a dose strong enough to bring RaptGenM to full mast almost immediately. He couldn't see it given his awkward orientation in the suspension of the vines, but it felt as though one of the many tentacles in the mass was poking and prodding his length all over. The experimental touching gravitated toward the head of his shaft before stopping for several moments; then without warning the vine pressed its tip against RaptGenM's cock and slowly opened up around it, pulling the velociraptor's entire length into its slimy depths in one long slow stroke.

RaptGenM quivered in the grip of the vines as he felt his maleness get swallowed by the tentacle's orifice. As the head of the vine bumped against the dinosaur's crotch it quickly tightened up, its rubbery tissues becoming skintight around the shaft it had enveloped to the point where its shape was visible on the outside of the tentacle. The vine held its constriction for a handful of seconds before gradually letting itself go slack only to quickly tighten back up and begin repeating the process. The tightness of the vine was unlike anything RaptGenM had ever felt before, better than any dinosaur he could remember and even somehow better than the wayward dragon he'd taken advantage of with his newly enlarged cock. The way the rubbery plant expertly milked his shaft had him on edge in seconds, his heavy balls already churning in anticipation of releasing another load of seed.

Just as RaptGenM was beginning to get a handle on processing the intense sensory experience engulfing his shaft he felt more movement further down his body as another thick tentacle snaked its way along the side of his tail. The vine darted up on top of the underside of the raptor's restrained body, nudged his tailhole once with its slimy tip, and quickly dove into him before he had a chance to even begin to process what was happening. An involuntary guttural moan of pleasure escaped RaptGenM's maw, heavily muffled by the tentacle buried inside of it. His tight ring, enhanced from the earlier experiments, easily spread open to accept the invading slimy vine just as it had done with the probes before. The body of the vine penetrating him was easily just as thick as the widest point of the mechanical arm's plug toy and he was able to stretch out in seconds to take it without the tiniest bit of discomfort. Every inch of the vine's forward movement lit RaptGenM's body up with an intense erotic buzz. His cock throbbed powerfully in the rubbery confines of the vine sucking on it and as the tentacle buried in his ass began to thrust itself into and out of him so too did the raptor start trying to thrust into the one sucking him off.

The vines penetrating the dinosaur continued their assault for several more moments until both of them began to rhythmically throb and pulse in unison. RaptGenM shifted and squirmed in their grip as he felt a dull warmth begin to grow in his stomach. Every throb of the alien plants pumped almost an entire pint of thick green slime deep into his body. The raptor's insides began to slowly expand as the warm goo completely filled his inner cavity and his lower body gradually adopted a very noticeable roundness as his stomach became more and more distended. The sensation was alarming, and although it did somehow feel good in a very abstract way RaptGenM found himself more alarmed by the stretching sensation that was rapidly making itself very apparent. Before it could progress to something potentially painful however, the pulsing of the vines tapered off and the dinosaur was able to finally try and acclimate to how heavy and swollen his body had become.

After experiencing the rush of a climax of their own the nest of vines slowed down for several seconds save for the one dutifully milking and suckling on RaptGenM's shaft. The one nestled in the velociraptor's nethers began to retract and pull its full length out from his body, but before his well-used tailhole could begin to close back up the tentacle was replaced with a second one and as soon as its tip probed into RaptGenM he could tell by feeling alone that this one was even larger. The dinosaur's eyes widened in shock as he felt the second vine take the place of the first, effortlessly spreading his sensitive ring wider open than anything else in the laboratory before it. Just like everything else there was zero pain despite how absurdly large the snake-like appendage felt; in fact, the velociraptor found himself enjoying the new vine even more than the first because every sensation that came with his tailhole yawning ever wider to accept bigger and bigger penetrations filled him with a sense of indescribably erotic pleasure.

The dinosaur shivered again as the second vine wormed its way into his soft inner walls. From the displacement of space alone RaptGenM felt his stomach gurgle as his insides struggled to keep their gooey contents, but as the larger tentacle began rhythmically pumping itself into the raptor the sloshing around eventually caused him to spring a leak and a generous stream of thick green slime began to trickle out of the corners of his mouth around the tentacle he was forcefully sucking on. Having reached release itself, the vines were now operating purely to obtain nourishment from RaptGenM. The larger tentacle provided more intense stimulation while the vine pulsing and rippling along the length of his cock continued to do its work.

A muffled groan escaped RaptGenM's maw as the dinosaur weakly thrusted his hips upward into the air with the limited range of movement availed to him by the tentacles. His senses felt dulled, his thoughts clouded in a haze of pleasure. A result of the copious amounts of ooze that had filled him well beyond capacity. The only part of the raptor's body that felt fuller than his guts were his hefty balls already churning with another full load of dinosaur essence. The velociraptor gently thrusted his hips again, yearning to inch himself just past the point of climax that he could feel quickly approaching. With the help of the rubbery vine milking his shaft, he finally caught it.

Another groan echoed through the small greenhouse as RaptGenM reached his peak, the dinosaur's cock coming alive in powerful consecutive throbs. Every contraction of the dinosaur's pelvic muscles released a thick load of potent saurian cum directly into the nursing tentacle where the fluid was quickly siphoned away deep into the hidden central stalk underneath the tangled network of vines. Each time RaptGenM released a shot of seed another one was expertly coaxed out of him with contractions of the vine perfectly timed to his orgasm, a milking sensation that prolonged his climax much longer than a normal one. RaptGenM's eyes lidded as he savored the intense feeling of the longest release of his life slowly morphing into a radiant afterglow. He'd never felt more spent before, and for a moment the raptor simply relaxed into the vines cradling him to fully appreciate the sensation washing over his body.

Though, after several moments of no movement whatsoever from the vines... they started again. The sudden shock of feeling the vine engulfing his cock immediately start sucking on it again surprised RaptGenM and as the dinosaur awkwardly shifted in their grip he felt the appendages buried in his maw and ass also begin to work themselves back into the pace they'd had prior. The realization slowly sank in that RaptGenM was probably going to be here a while.

Some time passed. How long exactly RaptGenM didn't know, but after several more intense orgasms the rubbery plant vines that had the raptor in their grip finally let go, the central stalk's hunger sated. For now. RaptGenM drunkenly clawed his way back into the experiment room and after many uncoordinated swings of his forearm managed to hit the button on the security pad to shut the hydraulic door to the greenroom. He collapsed backward onto his rear end against the wall beside the door and held himself there for a handful of minutes until he felt well enough to get back up. The swelling in his belly had gone down considerably, mostly due to the fact that a majority of the goop released into his body came pouring out the second the tentacles withdrew themselves, but there was still enough of it left inside of RaptGenM for him to feel the remnants sloshing around in his gut.

He roused himself slowly and tested his balance and coordination before feeling confident enough to leave the area. Whatever this was was a "fun" diversion, but it wasn't the exit. Out in the main hallway RaptGenM passed by another map and this time the velociraptor stuck around to take a closer look at the diagram and really study it. As his eyes traced the shapes of the rooms and connecting halls he noticed a pattern in their sizes and layout. The symbols above each of the rooms caught his attention and even though he couldn't read them he noticed that the area he just exited from was marked with the same pair of glyphs shown on the diagram. He quickly dashed back toward the mess hall and operation room he'd been in earlier to check their signs and compare them to the diagram too. Slowly, the dinosaur began to understand that this was a map of where he was currently standing; all of these shapes and lines were the rooms he'd been in. As his eyes traced the diagram a second time he ignored all of what he now correctly assumed were more experimentation rooms and followed the hallway all the way to where it ended: a long and narrow red zone with an arrow pointing out of it. The map also noted this as the "EXIT", though RaptGenM was left to make that guess on his own.

As he approached the area that had been marked in red on the map RaptGenM found that it ended with a staircase that seemingly led straight into the ceiling. On the wall next to where the stairs started was a large lever nestled into a hazard-striped nook. It was the only thing here that looked to be something of interest after several yards of nothing but metal walls and assorted power conduit.

The raptor tugged on the lever's handle and pulled it forward until it stopped moving. Instantly, the hallway filled with the sound of mechanical movement as yet another industrial hydraulic system sprung to life. At the apex of the staircase, where the steps met the ceiling, a line of bright light began to shine through. As the ceiling opened up and pivoted at its hinge the thin line gradually became an ever-lengthening rectangle that filled the hallway with an unmistakable orange-hued warmth. Sunlight.

An excited smile spread across RaptGenM's face as he quickly hurried up the stairs realizing it led to the outside. As he reached the end of the stairs the dinosaur looked out ahead of him and was met with the sight of an almost endless forest and a winding stream of rushing water twisting and crashing around an assortment of boulders about a day's walk away. He recognized the rock formation, he knew where he was. The velociraptor eagerly took a step forward but before the pads of his foot could finally touch the grass he'd been so desperate to find just a few hours prior he hesitated. A flash of memories of the laboratory filled his thoughts, recollections of encounters that were as bizarre as they were lewd. He could leave and perhaps never find his way back to this place, or... the remainder of the laboratory was literally just underneath his feet. As worn out and spent as he was the thought of what else there was to experience in the labs already had his scaly sheath plump with his retracted semi-erect cock.

RaptGenM's foot finally touched the ground... on the staircase. The dinosaur turned around and descended back the way he'd came.

Home could wait. For now, there were more experiments to do.
