Phenotype
A genetically modified scientist on one of Earth's first colony missions has a surprising bit of self-discovery during the long voyage. Contains: a lot of lust-driven, animalistic M/M sex between two reptilian males.
I wrote most of this over the last winter, inspired by the writing of my always-great mate :)
****
Krelian entered the stasis bay quietly. Even though he had been aboard the 'Pathfinder' for nearly three months, the room still inspired in him a sense of awe that approached reverence. It was almost impossible not to feel that way, looking upon the thousands of neatly-stacked, surgically-clean cryocapsules that held the colonists. For the hundredth time, Krelian found himself wondering what it was going to be like for them, to go to sleep in orbit above Earth, and then awaken two years and hundreds of light years distant.
They were all healthy young adults, but other than that their features had more differences than commonalities. Everyone onboard had been genetically adapted, for both their role in the colony-to-be and their own personal preferences. They were covered in coats of sharkskin, fur and scales; they had wings and antennae and tails and claws. Yet, despite their anatomical differences, they all retained enough humanity in them to be recognizable as the people they once were. It was terribly odd, seeing all his old friends, coworkers and colleagues in new and unfamiliar forms. The sight made Krelian feel ruminative. What changes were they going to have to undergo once they reached their new home?
Of course, looking down at the shiny, void-black scales that covered his upper right arm, Krelian was reminded of the changes he had already adapted to himself.
The bioengineers called his form a 'Geck'. He very much resembled a streamlined, bipedal gecko, purpose-transformed to suit the rigors of engineering in deep space. His feet ended in large, splay-toed pads that could stick to virtually any surface, and the same was true of his smaller, more delicate hands- of which there were four! It had taken Krelian some time to get used to having six limbs- well, seven with his tail- but it was undeniably useful to be able to scamper up and down any surface on the ship and still have hands free for working. His body had a pair of large, lidless eyes that could effortlessly absorb the finest details and see into parts of the infrared and ultraviolet spectrums, and a pair of earfins that reflexively perked up and caught even the faintest sounds. Krelian was still working out what tastes meant what with his long, fork-tined tongue, but had figured out his ultra-sensitive tastebuds well enough that he hardly needed his tools some days. But the strangest change of all was still taking some getting used to...
Krelian now had a pair of sensitive, tapered, crimson-red reptilian hemipenes, something the biotech had neglected to inform him of before he had begun the exhaustive transformation process. He could never quite sate his lust; there was too much sensation in his cocks, too much sensuality in his tailbase and scales. Krelian knew it was more than just the thrill of interstellar travel and the allure of the thousands of naked bodies under his watch; his mind was at the mercy of the reptilian hormones flooding his bloodstream. All he could do to quiet the bestial urges that occupied his mind most of the workday was to let them out...
Krelian put his toolbox down on the ground in front of one particularly rich row of suspension pods. Four different males and one female were stored inside them, all reptiles. Smiling at his unwitting models, the Geck slowly began to pull down his tight jumpsuit, wiggling all four of his arms out before unzipping the tail sheathe and fly. His hands lightly traced the slightly sweaty scales of his genital slit and backside before bringing two of his fingers up to his muzzle, tasting the musk with a flick of his tongue. All morphs had perfectly optimized anatomy; no bodily fluids got in the way of more essential- or pleasurable- activities...
The Geck's nimble fingers worked quickly, retrieving a thick, black vibrator and a bottle of lubricant from the hidden depths of his toolbox. Using two of his arms to lube up the well-used toy and the other set to fondle his own ass and lubricate his tailhole, the lithe lizard began to slowly spread his webbed feet into a wide stance. Lifting his tail up in the low-gravity chamber required an effortless flick...
Krelian didn't even bother to stop himself from moaning when he pushed the dildo just past his tailhole. A shiver ran from his neck all the way down to his tailtip as his tensed, scaly cheeks parted around the toy. His anal passage yielded to the thick silicone with a short, wet squelch; Krelian had grown quite accustomed to his routine over the last few months. The leathery orifice was as tight as ever, but now he knew just how to use it...
Moaning again, the lizardlike scientist flicked out his tongue to taste his own arousal. The wet, artificial taste of lubricant was heavy in the air, but Krelian could also smell his faint male-musk. He began to push two of his wide fingers into the swollen scales of his genital slit, and found the pouch tight but yielding. Sure enough, his fingers quickly found the source of the dull, throbbing pleasure in his slit: his hemipenes.
Krelian couldn't help but feel a twinge of embarrassment, one strong enough to make his dark cheeks blush. The young scientist had been a human most of his life; even though he embraced his change of species enthusiastically it still felt strange to him, at times. Having two penises was something that made him really feel like... something else. Was it so strong there because of some primitive connection with his reproductive functions, or was it the fact that it felt too good to be true? Krelian smiled and stopped pushing his dildo in as he felt the slick, tapered lizard-cocks evert out in his hands, soft but hardening...
"Why'd you stop?," growled a voice from just behind him.
The Geck gasped and nearly fell flat on his snout as he scrambled around, dildo coming free from his tailhole with a wet pop. Krelian collapsed to the floor in a pile of tangled clothes and limbs before staggering back to his feet, hemipenes dangling freely from his puffed-out slitlips. "A-ack! What the name of... of- decent human privacy!- are you doing here!?"
"I'm checking in on you, ship's orders. Do you realize you haven't talked to anyone else in three weeks!"
Looking up, Krelian saw who his unexpected guest was: Merrus Mairk, the section security chief. Merrus was a Rex- seven feet of armored scales and pure muscle that quite closely approximated the concept of a 'living weapon' in Krelian's mind. The saurial morph had a tooth-filled muzzle, hulking arms that ended in vicious claws, and broad, three-toed feet topped with massive, curved talons. Even though it was called a Rex, Krelian suspected that the genetic lineage owed a lot of inspiration to raptors and crocodiles. Like his own six-armed, twin-cocked form, the scientist thought of it as a particularly inhuman morph. The Rex had to rely much more on his sturdy tail to balance his bulk, and it forced him to hunch down into a predator's profile.
"You know, Captain Tamert actually thought you were up to no good," the security officer said, casually throwing a massive, half-disassembled plasma caster over his shoulders while giving Krelian a smug, toothy grin. "I told her she was being paranoid. Pathfinder agreed with me, but of course it knew *exactly* what was really going on. It didn't say what you were up to though, oddly enough. The ship is awfully polite for AI, wouldn't you agree..?"
"Ah! Sure! T-that would be correct, yes!" Krelian managed, nearly tripping himself again as he covered his exposed hemipenes with his tail. His cheekscales smoldered with frustration and embarrassment as his aroused members visibly deflated. "Yesss... situation all normal here..."
"Right. No, no; I'm not going to tell her anything," Merrus said, with a razor-toothed smile, "on the condition that you refrain from this sort of... activity... for the rest of our voyage. As you are more than aware, it is *exceedingly* unprofessional. Understood?"
"Yes sir," Krelian hastily replied, picking up his toolkit with one hand, his clothes with another and preserving what little remained of his modesty with the other two. "I'm sorry, sir; I... I don't know what got into me. It's just... well..."
"Explain yourself if you wish; I don't think it changes the facts of the matter." the massive reptile commanded, still smiling. Krelian wasn't sure if the commander was trying to be friendly or intimidating.
"They...w-well... they never told me what it was going to be like in t-this body..." Krelian admitted, his muzzle curling into a sour frown. "It... it just feels so strange! Do you have any idea what sort of synthetic hormones are running through my bloodstream right now? It's not something you can simply will away; it's a biochemical process! And it's worse than being a bloody teenager again!"
"Is that all, doctor?" Merrus asked.
"Well... I've also had this *unbearable* craving for crickets, but thus far I've managed to keep that one in check..." Krelian said, half under his breath.
"Good to know you're not a complete animal." Merrus growled. "I don't need these excuses; you are to restrain yourself and *not* get your rocks off during duty hours. And you know, there are better ways of dealing with nature's little problems than giving half of my security team a camshow every duty shift."
"WHAT!?!" Krelian shouted, both of his lidless eyes bulging as wide as saucers. "They *watched* me!? How!? You let them!?"
"To answer your questions, doctor: through the surveillance system and of course I did. Do you think we just turn off the cameras every time someone embarrasses themselves? Hah!" the Rex replied. The twinge of annoyance in his voice quickly drowned in a roar of laughter.
"Oh-oh dear, oh dear, oh dear..." Krelian stammered, fidgeting about before suddenly deciding to pick up his clothes. "This is a... suboptimal outcome..."
Merrus continued to laugh. "Heh, stop worrying! You're not actually in trouble or anything. The captain is just worried beyond all reason someone onboard is an Eden-ist terrorist trying to do what they failed to do Mars. After an exhaustive review of the evidence, I can safely conclude that no one who masturbates as much as you could possibly have time to plan or execute terrorist activities."
"Would you stop that already!? I get it!" Krelian snapped, awkwardly pulling one of his splayed footpaws through the bottom of his jumpsuit. His black cheeks were flushed dark brown with embarrassment. "I... I told you! It is hard to deal with!"
"So was the zero-g training and colony school. Deal with it!" The Rex grunted, pausing to give Krelian a firm slap on his scaly rump, "Or at the very least, get it out of your system on your own time."
The spank broke Krelian's equanimity. Growling, the aggravated Geck flung himself at the much larger reptile, surprising him and sending the two scalies crashing to the floor and making the soldier's weapon clatter away from them.
"I am *not* some effeminate, simpering milksop, you cretinous baboon!" Krelian growled, his tail flicking behind him in sympathy with his anger. "I was a Nobel prize finalist! My cryogenics research is a small but critical part of what made this expedition possible! I will not be talked down to by *you*, not on matters of morphological biology! I just won't stand for it!"
Laughing slightly, Merrus smiled at the lizard atop his chest. "Woah there! Why don't you just calm down and..."
"Stuff it!" the scientist interrupted. "Look, if you don't believe *me*, fine! Believe this!"
The Geck suddenly pushed his fine-ridged paws against the lower half of Merrus's tight bodysuit and tore them down, snapping the spandex-like garment about the saurial's muscular ankles.
"Doctor Krelian, I don't know what you think you're trying to do right now but this is exceedingly unprofessional behav..." Merrus began to say, before his words dissolved into a sharp, saurial hiss. Two of Krelian's fine-ridged paws had found his slit and were passionately massaging the supple scales there.
"I didn't know much about the bodies they gave us when we left, but now I've had time to read all the manuals and research papers. I think you'd be surprised about some of the things our forms were designed to do, Mr. Security Chief..." Krelian hissed, pushing the Rex's head downward and to the side. The gecko-like scientist gently pushed his muzzle against Merrus' earhole and flicked out his forked tongue, teasing the soft scales.
"Oh-h-h... w-wow..." was the only thing the Rex could manage, before his tensed body practically melted down onto the floor. Krelian continued to lick around his sensitive earhole for several long seconds, each tongueflick drawing a gentle moan from the burly dinosaur. The feeling of the warm tongue swirling around his recessed earparts, while two hands expertly fondled and tickled his slit was incredible.
Krelian swiftly moved down to Merrus' neck, opening his muzzle wide to suck on the thick, loose scales. The Geck was an expert with his forked tongue after months of licking himself, and had studied the anatomy of the Pathfinder expedition's morphs with fastidious passion. He knew even that even the armored, musclebound Rex morph had plenty of sensitive, soft, and sensual places he could exploit with devastating effects...
"Ahhh... why didn't I figure this out earlier! It's obvious! They did this to us on purpose, Mr. Mairk. Long voyage on a cramped ship, minimal communication with the Sol system... there are only so many ways to pass the time. Sex does so rather nicely, with the added bonus of forging stronger group-bonds in the crew. I don't know what bright young technocrat hit upon the idea- or who gave final approval- but the results are... mmm... not debatable..." Krelian said, pushing his tongue into Merrus' muzzle and finding it quite welcoming. The Geck slid his upper arms up under the Rex's burly arms and began to gently press under his armpits, up into the leathery, almost white-hued scales. The armor of the Rex was thin there, sensitive; Merrus actually squirmed a little as he realized he was being *tickled*...
Krelian broke the kiss quickly. "Yeah, I bet you didn't expect that, either? Your new form isn't inured to touch like your old one, reinforced dermal tissue notwithstanding. Just have to find the sensitive places on that big, scary body of yours... well, no. I know exactly where they are..." Krelian whispered, moving his lower hands down towards the saurial morph's backside, lifting up the burly Rex's tail and cupping the firm, scaly flesh of his ass. The Geck's finely-ridged fingers dug into the muscled tail and cheeks, finding them deliciously firm but still yielding...
Merrus' eyes went wider and his breathing grew heavy as this new stimulation hit him, feeling absurdly vulnerable underneath the small, soft-scaled Geck. He couldn't even stop the Geck's long tongue from pushing past his lips again and pressing directly against the roof of his mouth- directly into his sensitive vomeronasal gland. But there was no question he could wrestle his way out from Krelian's scaly bulk; all he had to do was...
Suddenly, the Rex was thrown into a burst of hot shivers as two slimy gecko hemipenes thrust into his tight slit. Merrus hissed in surprised arousal; the reptilian members were throbbing and erect, perfect for pressing into his own hidden, saurial hardness... and just beyond, into his internal testicles. Squirming against Dr. Krelian's sleek scales and trapped in the throes of sexual pleasure, Merrus was all but helpless. A wet, squishing sound echoed through the vaulted stasis bay as two slick lizard-penes frotted against the Rex's cock inside his slit, quickly filling it with musky, lubricating reptillian preseed. Merrus moaned and found his mouth again filled with lizard tongue; Krelian was deliberately thrusting in such a way to grind directly against his throbbing, tapered glans...
What finally did it was when Dr. Krelian's lower hands began to play with his tailhole. The Geck slid a single ridged fingerpad upward and began to press against Merrus' tailhole in gentle, teasing strokes, not even trying to press inward. The burly soldier let out a soft, animalistic moan as he felt the gecko's fingerpads caress and tickle his leathery, taut pucker. It was too much; the Rex couldn't escape from the sexual pleasure saturating his every nerve, bypassing his every defense and silencing his protests before they could leave his thoughts...
Merrus felt his tail twitch and his knees shake as his orgasm approached, Krelian's twin cocks rubbing the head of his saurial cock so quickly it felt like one continuous motion. The soldier's body bucked against the hard floor under him as he came, filling his own slit with heavy spurts of thick, hot saurial cum. Krelian's thrusting slowed in pace but didn't quite stop, as the thick, gooey semen made his thrusting noisier and more difficult. He felt a stream of hot, watery cum jet against his twitching member as the scientist joined him in climax. The Geck's earfins twitched as he barked a few animalistic chirps, while Merrus let out a low, growling roar.
Overstimulated to the point of pain, Merrus pushed Krelian away and then promptly collapsed onto his back, shuddering with relief and residual ecstasy. Finally freed from the press of the Geck's hemipenes, the emasculated dinosaur's maleness finally pushed free of his slit. It was rock-hard, coated in the sticky, dripping product of their labours.
"Hm... sorry about that. I honestly didn't know it was possible to make a morph of your model cum even before the penis everted." Krelian said, pressing his body back up against the overwhelmed Rex, kissing and licking each row of hard, scale-clad abdominal muscles. "I'll have to note that in your morph's file later."
"W-wait... let... hold on doct..." Merrus stammered, shivering as his toned muscles were caressed by the lithe gecko's muzzle and tongue. The smaller morph was like a ball of pure sexual energy, moving so quick from one pleasure center to another that the solider couldn't even think straight. He felt Krelian scoot up forward on his chest, licking his neck and cheeks while slithering his nimble tail around the Rex's sensitive erection. Suddenly, Merrus had another, more pressing impediment to speech: the doctor was pushing a pair of gecko hemipenes right against his lips.
"Come on... lick it clean..." Krelian whispered, rubbing a softening hemipene over Merrus' snout, before repositioning it back at the saurial security chief's lips. "Yeah... if you're such a proper, self-empowered human, you won't be feeling a burning need to taste fresh ejaculatory fluids with your vomeronasal gland..."
Eyes closed, Merrus opened his scaly lips and pressed his muzzle forward, not stopping until his snout was flush with the Geck's soft, black-scaled slit. He suckled on the softened, cum-sodden hemipene until every delicious millimeter of the fleshy reptile cock was in his mouth. Salty-sweet, masculine flavours tingled on his tongue in a way that made him feel homesick. Homesick for a jungle, his pack, the nuzzle of a mate... wait... that *couldn't* be right...
"Yeah, didn't think so. Suck my cocks... suck them both good, you sexy bitch..." Krelian hissed, pushing an erect hemipene into Merrus' maw. The security officer had realized that things were not going exactly as planned some time ago; having a twin set of penises in his muzzle- one of which had just been slitfucking him- was one clue. Hearing the soft-spoken, fastidious Dr. Krelian calling him a 'sexy bitch' was another. But... but it felt so sexy, so *right* to suck on the gecko's hemipenes, to taste each fresh tongueful of semen and prefluid...
"You see? Thissss... this is what I meant... you're no more in control than I was..." Krelian hissed, pulling on the back of Merrus' head as he humped into it, filling the Rex's snout with the potent musk of his maleslit. "Instincts. Pheromones. Lust. Desire. There are a lot of factors influencing your behavior right now, but you are not in control of the majority of them..."
Merrus felt Krelian slide off his muzzle, then take hold of his body using three surprisingly strong hands. The Rex's tongue lolled from his maw as he was rolled onto his belly, finding the hard steel surprisingly nice on his re-hardening maleness. It was warm and slippery enough to thrust against, thanks to the spilled cum pooled there.
"Ahh... as a matter of fact... we would probably be done already if I wasn't dealing with the mixed blessing of having a lizard's reproductive system." Krelian said, brushing artificial sweat from his muzzle as he repositioned himself behind Merrus. "Have I impressed this on you properly, Mr. Mairk? I have two penises. Two. You can't expect a human mind to deal with this unhindered. It's a good thing we have homosexuality and contraceptives. I think I'm going to have to fuck you now, by the way."
Merrus managed to cough out a protest after swallowing the excess sexual fluid in his muzzle, "Krelian, stop..."
The Geck suddenly hiked Merrus's tail straight up with two hands, while his other two grabbed the larger reptile-morph and pulled him into a tight hug. Merrus pushed his taloned foot up and pressed it against Krelian's stomach, preparing to kick him off. But before he could, the nimble gecko-morph snaked his muzzle over the Rex's muscled leg and into the exposed softness of Merrus' ass...
"...get away from there..." the security chief hissed through his teeth, trying to find leverage for his foot. Krelian's short height and incredibly powerful grip made it nearly impossible to try and dislodge him, despite the scaly scientist's smaller mass.
Krelian pushed his muzzle right underneath Merrus' thick, raised tail, pressing his scaly lips right against the saurial soldier's tailhole. He kissed the leathery, quivering flesh quickly and passionately, then began to lick around the rim of the tensed orifice.
Merrus bit his lip as his tail curled upward on instinct. Why did *that* feel so good? "...ungh..." he whined to Krelian, bowing his head and shivering as the other reptile continued to lick his smooth, scaly ass. He hoped it wasn't going to go any further, but he wasn't sure if he wanted it to stop...
But the Geck wasn't content with just the outside of his unwilling mate's rump. Krelian began to wiggle his powerful tongue against the Rex's tailhole, forcing the slimy, warm appendage inward. Merrus gasped, trying to pull away only to realize the Geck's paws were firmly stuck to his smooth scales. He felt his anal virginity hold for a few terse seconds, but a single moment of relaxation was all it took. The burly Rex moaned, hissed and shivered as the scientist's long, twin-tined tongue eagerly plunged into his tailpassage, slithering deep into his toned, muscular backside.
"F-fuck..." Merrus swore, gasping for breath. His whole body was tense; he felt paralyzed by the feeling of that warm, slippery gecko tongue exploring his tailpassage. Krelain's reptilian appendage was easily strong and long enough to reach his deepest, most sensitive places, now that it had conquered his tailhole.
The bizarre but sexually-electrifying feeling of having a tongue slurp through his tailpassage was quickly destroying any hope Merrus had of spurning the scientist's affections. Though the security officer had twice coupled with other men, he had been *quite* insistent on taking other males in the way to which he was accustomed with females. Even though he knew their bodies possessed almost perfect metabolic efficiency, he didn't *want* to think of his tail-hole as a sexual organ. But now, actually experiencing it, *feeling* it... it was impossible to deny. Nerves he never knew he had lit up with pleasure as his tight hole was tongued open again and again, a little bit easier every time. Merrrus felt his cock throb and re-harden, tingling with a cool, warm heat that seemed to flow into it whenever Krelian's tongue was pushing into his rump....
With a sound like a wet kiss, Krelian pulled his tongue out from Merrus's upturned ass, stopping only to give the firm, muscular scales a pair of quick spanks. The Rex shivered as the gecko's sticky paws peeled away from his sides, and the lust-addled scientist began to grind a hard and slick hemipene against his quivering, freshly-despoiled tailhole...
Merrus felt a pair of fine, splayed footpaws stick to his thighs as Krelian positioned himself, squeezing the Rex's tail upward between his four arms. Growling with lust, Krelian wrapped his lower hands around Merrus' belly and then gripped the saurial's shoulders with his upper set...
The security officer sucked in a breath as he felt the Gecko on top of him start to hump against his tailhole, feeling tremendously violated but incredibly aroused at the same time. Head hung low, he could see his tapered, reptilian member throb and stiffen between his spread legs, jutting from the puffed-out lips of his slit like a crimson obelisk. Preseed was pouring out of his member's narrow, arrow-shaped tip, gathering into fat, milky beads before raining to the ground and splattering into the musky, white mess of cum under him...
"You... might... have a point..." Merrus admitted.
"Yes, I do. Now. Sssssubmit to me..." Krelian hissed.
Merrus whined and bowed his head, wordlessly but explicitly submitting to the small but clearly superior male. Sweat rolled down his tensed, bulging, scaly biceps as he braced his hands against the ground, easily supporting their combined weight. Waiting in tense anticipation, he smiled, feeling his thoughts grow hot and incoherent. The gecko's cock pressed firmly up against his ass, grinding against his hole but not quite going it...
Krelian did not keep him waiting. The Geck eagerly thrust the whole tapered length of half of his reptilian equipment up into the now-eager and well-prepared tailhole under him. Merrus moaned and shivered, his thick tail brushing against Krelian's muzzle as he felt his ass yield to the dominant male. The pre-soaked lizardcock made a wet squish as it spread open the soldier's anal passage, leaving warm spurts of preseed everywhere it was squeezed...
The gecko's tongue had been a new world of sexual experience for Merrus Mairk, but Krelian's cock was different still. The stiff, hot, slick and fleshy cock didn't just explore his tailpassage; it *claimed* it, forcing it open in strange and uncomfortable ways that somehow felt more stimulating than any sex he had ever had before. Again and again, his sensitive tailhole was speared open by the tapered, slimy gecko-cock, his bowels filled with the masculine length, then...
...suddenly, Merrus felt Krelian's hemipene press into something inside him that made the sensitive head of his cock throb. Hot bursts of arousal spread from deep inside his sensitive ass down the length of his throbbing reptilehood in quick succession, and he felt like he was going to pee cum. Unable to access enough of his brain to speak, Merrus cried out in a high-pitched, warbling roar, hiking his muscular tail upward until it was pointed almost straight into the air.
From the sound of things, Krelian was beyond words himself. The Geck was only able to speak in chirps and barks as his hips pushed and pulled into his mate's meaty backside... though he growled with pleasure when Merrus began eagerly bucking his backside into each thrust. Unlike earlier, they were both pulled together in ecstasy.
Merrus squeezed the unfamiliar muscles in his tailbase and ass as tight as he could, trying both to pleasure the male mating him and bring his own climax sooner. It worked; Krelian's hemipene pressed right up against his prostate after his strongest squeeze and began to cum, blasting hot jets of Geck-seed right against his throbbing sex. Merrus sucked in a deep breath and cried out in a rolling, almost avian cry as the feeling of being well and truly bred brought him to his own peak. The Rex felt his girthy dinocock twitch up and slap his belly as he came, his armored, musuclar body trembling with pleasure as the moment overwhelmed him. Hot seed was gushing deep into his tailpassage and making a total mess of his backside, while his own orgasm was mostly spent against his abdomen and the floor. The smell of musk and sex saturated his snout; most of his body was covered in spent fluids, and more still trickled from his slit, tailhole and muzzle. Even stranger was the knowledge that the quiet, intelligent Dr. Krelian had hit him like a one-man orgy.
The two scalies panted together as they came down from the sexual plateau, neither quite moving or speaking for several pregnant seconds.
"Mmm... ssssorry," Krelian moaned, unsticking his six paws from Merrus one at a time before rolling away from the Rex's muscular back with a wet thud. Big eyes closed, smile on his muzzle and small chest heaving in deep breaths, the Geck looked exhausted but happy... which exactly how he felt.
"What in the name of fuck was *that*, doctor?" Merrus coughed, curling his tail inward as he sat up. He turned just in time to watch the oddly-arousing sight of Dr. Krelian pushing his hemipenes back into his slit. "I have never, *ever* been on the receiving end of..."
"Weeks of pent-up mental torment. I do not enjoy the sensation of... losing control. When the sexual urges hit me after the change, I... took care of them myself instead of with other crewmembers. You kept calling *me* an animal, but I think I'm the only one in this entire section who hadn't been driven to hump the brains out of anyone else. What I failed to realize was the possibility the arousal was the result of a biochemical process engineered not to respond to self-stimulation. Letting go of my inhibitions was difficult, but when I found out that my... problem... was public knowledge, you changed my optimal sex strategy away from that rather oppressive equilibrium." Krelian said, words pouring from his muzzle.
"...and yeah, let me just say you have some very... descriptive... bedroom talk..." Merrus added.
Krelian pressed his lips against Merrus' scaly muzzle and silenced him, though it was a softer, almost romantic gesture compared with the fiercely-passionate snogging he had received earlier. The Geck stopped the kiss slowly, licking his lips clean of the Rex's sexy, masculine taste. "Sorry. I was... nervous. I didn't know what to say, so I said everything. But I suppose much of my reaction was... a little irrational, or at least egotistical. Oh well!" Krelian said cheerfully, standing up and shrugging his upper shoulders before planting one last kiss on Merrus' neck. He then began walking back towards his discarded tools. "I feel great now!"
"Hey, doctor! You made your point, but you're still not off the hook! The shift rules are there for a reason!" Merrus said incredulously, still too surprised to stand back up. The warm trickle of semen from his sore tailhole was quite distracting... and not in a bad way. "How about less sex on duty, more sex off?"
Krelian turned around, slowly flicked his long, black tail with his spin. The Geck blushed a bit as he met the larger reptile's eyes and smiled. "Er... sure!"
