#202 of Commissions

Commission for Siennathevaloinx!

Sienna really should be more careful cleaning up the lab. Who knows what she might unleash? An escaped xenomorph on a small research ship is bad enough. Getting one mixed up with an experimental transformative goo is even worse! The crew doesn't stand a chance ...

A slimy alien story featuring: goo/slime, oral vore, cock vore, transformation, trait absorption, facehuggers, breeding, and more!


Geez, didn't anyone ever clean up in that dingy lab? It looked like nobody had even bothered to dust in years. And that wasn't to even begin to speak of the floors. Strange blue strains from corner to corner. Just what were they doing in there that required making such a mess? Sienna wiped at her brow just looking at the mess of it all, feeling as if she needed a shower just for stepping in the room. They'd never told her to stay out of there, exactly. They just never asked her to actually go in. Well, the valoinx was a cleaner of great initiative, and she'd show them exactly why she deserved a promotion. Not that there were many promotions to be had while drifting out there somewhere in deep space, well away from the nearest resupply station, hovering about as a mobile research vessel doing who-knew-what. She didn't know why they had to spend so long in the middle of nowhere.

The great big tanks around the room mostly looked empty. It was hard to see through the glass for whatever reason, but she didn't catch any sort of movement or sound. Maybe they hadn't even started! Well that was just embarrassing to think about. All those weeks spent floating there in the great void and they hadn't even made any progress on whatever they were supposed to be doing? Ah, well, it wasn't the janitor's job to worry about it. She just cleaned the floors, and that was precisely what she started doing, breaking out the mop and bucket so she could start scrubbing those stains from the metal surfaces. They were certainly stubborn, staining her mop blue as if it were a paintbrush. It took lots of wringing it out in the bucket to get it clean again, and she continued, idly whistling to herself as she made her way back and forth, the sound echoing around the dingy chamber in faintly eerie fashion. But it was better than the dull rumble of the engines. The silence got a little creepy at night sometimes, when everyone was sleeping but her.

That glass was so smudged too. No harm breaking out the rag to give that a proper rubdown. She still couldn't see anything on the other side though, even after working up and down one of those tanks and making it shine. Yet the moment she turned her back to it, there was a sudden CLINK as something banged against it from the inside, letting out some sort of shriek that startled her badly enough to make one of her own. She lost a grip on that rag and sent it soaring across the room to splut down on that freshly-mopped floor. It was slippery in there, leaving her sliding about, flailing her arms until she caught her balance on the edge of a nearby control panel. That would have been fine, if her palm wasn't firmly planted on a big, red, scary-looking button. The screaming alarm and bright red spinning light overhead told her she'd just done something bad. Really bad. Like, lose her job and worse bad. There was really no other course of action than to get the hell out as fast as she could and hope no one ever figured out who was in there. Though the cleaning supplies left behind were a pretty sure sign.

She heard the whirr of machinery behind her, and then she heard something splashing down as if being poured from a large bucket. Soon after there came that shriek again, that horrible, hissy sound that left her shuddering her way right down the hall, rapidly making her way back to her quarters so she could hide. That meant she missed out on the experiment, as did all the researchers who had set it up. She didn't know what they were called, but that was a xenomorph held captive in that tank, shiny and black but currently coated in a thick, blue, experimental goo. It writhed and it thrashed about in captivity, beating against the glass aggressively, its body shaping and changing thanks to the effects of that strange substance. Once fully transformed into something smoother, goopier, and that same, distinct royal blue, a new species was born. In time, she'd come to be known as Gusher, but she was a nameless creation of science gone wrong. And she had already escaped.

The alterations to her genetic structure allowed her to take on about any semi-solid shape she liked. There were plenty of gaps in the containment chamber, cracks between the panelling or the vents. She figured out precisely how to use her altered body to slip through and free herself from captivity in a matter of seconds. They might not have had any line of communication, but she was a far more intelligent creature than those researchers knew. And she was going to show them exactly how badly they had underestimated her. She wasn't exactly silent, stalking about the ship with slick, goopy steps, leaving a trail of thick slime everywhere she went, but the blaring alarms drowned everything out, plunging the ship into chaos as people abruptly rose from their beds to find out exactly what was going on. Chaos was good. She could use that.

When the sound of boots tromping down the hall towards her alerted her to an armed group of security officers, she quickly took to the vents above. They were a squishy place, the type that a regular xeno would have had a great deal of trouble getting through, but she could reshape her malleable form with ease, slipping and sliding along overhead with nothing but a messy schlorping sound to announce her presence. She darted through the ship at high speed, moving her lubricated body with ease, hardly needing any time to adjust to the way it worked. It felt as if she'd always been this way, the perfect lifeform made somehow even more deadly. She moved along until she found the perfect target. All that transforming made her hungry, and there was no better person to consume than a stubborn, lazy security grunt who hadn't bothered to get out of bed for the big alert, probably assuming it was another malfunction. It wouldn't have been the first. He lay there as if pretending to sleep, though of course slumber was far off with those alarms going. The vent led right above his quarters, and there was nobody around to hear him scream.

He was a meaty one, too. There was such muscle on that sleepy lion, and a nice big dick too. Such a perfect first meal for the newly transformed xeno if she was going to fill her belly. Her new form allowed her to exude a generous amount of pheromones, simply by being near her chosen prey. It just so happened that fine scent was the sort that proved intensely arousing to the creatures who had captured her. She wafted that aroma from her hiding place, leaving the lion to suck it up. The effects were almost immediate. One good whiff of that perfume and he was sniffing the air, squirming a bit where he lay, showing a growing bulge beneath the covers. Good. A nice big cock on him. She wasn't going to let him use it or anything, but some solid, well-hung stud was the perfect meal to deal with the enormous appetite she'd worked up in captivity. A strategic dripping of her slime from the vent above allowed it to splash right into the lion's open mouth, overwhelming him with a sudden rush of potent flavour that left him far too turned on to ignore. His eyes opened wide, even while he was left smacking his lips, sucking his tongue to get the most out of that enticing sample. He was far too distracted to see her coming.

Rather than knock the vent opening off, she simply slipped through the cracks, dropping down with a squelching thud right beside his bed. He might have been lazy, but he definitely heard that. Yet what was he going to do, trapped alone with the great big xenomorph cutting off his only exit? He sat up sharply in bed, casting aside the covers to reveal his completely naked form, but that was about as far as he got before she reached out and snatched him by the wrists. Despite the lust overtaking him, he still fought her, resisting with all his leonine might, setting his bulky form to bulging with muscle, but it was all for nothing. He couldn't possibly hope to overpower a regular xeno, much less one who had been subjected to that drastic, gene-altering experiment. It had all gone so horribly right, leaving her even more powerful than the rest of her species, and that meant that big cat was doomed.

She clutched him by the shoulders, digging in her claws but not drawing blood, looming close for a while. It would have been easy to just tear him apart, but that wasn't how she desired him. Her new body was so flexible, so soft and easy to bend into new shapes. It would have been foolish not to take full advantage of it. Wafting her pheromones from close range meant his struggles were ceasing with every moment, replaced instead by confused, horny squirming. His cock was hard enough to spurt, shooting heavy droplets of precum straight up and onto the goo-xeno's body. Opening up her jaws wider, and then wider still, she slowly extended that inner jaw, but rather than penetrate him with it she instead used it to bind him, constricting it around his throat just tight enough to keep him from crying out for help. That let her take her time in drawing him into her mouth, slipping him between her deadly teeth, overwhelming his vision with the slimy darkness of her throat. A good, slick suck on his maned head was enough to mat that fur down with drool and slime alike, soaking him to the skin, robbing him of that lion dignity once he was properly slicked up. Then it was a matter of tugging him deep, enveloping him in the loudly schlicking confines of her humid insides, overtaking him with the forceful tugs of peristalsis as she forced him down her gullet to make for her first meal in that new form. The first of many, she hoped.

Soon the altered xeno was left writhing in pleasure as she swallowed her victim whole. He was much the same. Those pheromones carried well on her hot breath, ensuring he was getting a double-dose on the way down her throat. He certainly didn't put up much a fight, though sometimes he seemed to almost pretend, as if some instinctual side still knew he was in trouble. Faint shoving, even a little kicking, but it was all for nothing. The only thing that served to accomplish was getting him coated in that clinging slime, lubing up him for that undulating swallows gripping all around his body. She nearly crushed his shoulders with that squeezing gulp, dragging him into her depths, turning him into a muscular bulge that mmfed in pleasure and confusion alike on his way in. Her insides weren't especially hostile, but they were plenty warm, leaving him lightheaded and weakened, too horny to know any better than to thrust and try to hump that gooey creature even while she was feasting on him. She kneaded those fangs of hers along his chest, inched them down his spine, nibbled her way to his waist, messily devouring him all the while. Such an indulgent feeding process meant splattering the walls with slime, painting down his quarters with the substance that was part of her now. And soon, he was going to be part of her too.

She felt him shuddering and writhing all over when she got to his dick. It was intensely hard, pumping away, dripping, spurting. Getting a good feel of its heft involved her slipping her inner jaw beneath it like a tongue, toying with it until it gave heavy spasm and left the cat groaning deep inside her. A good, meaty grip of his ass was something worth pausing in all her gobbling for, just to admire that fine rump she was eating, massaging him while she played with his dick, tormenting him with pleasure. It was all too much for his pheromone-laden senses to handle. Every breath he took just amplified his lust, made him harder, made his balls pump tight and clench. A lash of his tail and a muffled cry in her throat went along with him covering over her chin, then into her open mouth as she stuffed him in there with a hard shove on his ass, not even letting him finish before she resumed feeding herself.

After that sudden eruption, it was time to toss that phallic head straight back and leave his legs pointing straight up in the air, kicking about along with his lashing paintbrush tail. He was left stewing in an afterglow that blanked him right out, his muscles moving all on their own, nerves firing off without his consent. The tuft of fur on the end was soaked in her blue, flicking little spatters onto his surroundings as if applying one last splash of paint to the canvas that was the goo-soaked room. One long, slippery slurp rang out loud enough to echo as she dragged that big handsome cat down to her belly in one final swallow, working those throat muscles hard around his every single muscle until he was naught more than a pair of paws between her teeth. She reached up and pressed a single extended claw on each hand into his soles, pushing down just firmly enough to tuck him away and seal his fate as food for the escaped xenomorph.

One last gulp left him plunging into her gut, where the process of rapidly assimilating him began. It wasn't quite regular digestion. He probably would have been thankful if he knew how harsh the acidic alternative would have been. The lust clouding his mind was already far too powerful for anything else to matter. Even melting down into a gooey state, converting to more of that blue substance that the xeno herself was made of. She assimilated him with every sloppy churn, squeezing down on his muscular form, squishing him up taut until he couldn't move, could barely even squirm. Simmering and smoothing over his features, she absorbed him not just for nutrients, but for genetic data as well. He enhanced her shape, adding some womanly curves to her thighs, distributing the fat in a way her prey might have found attractive. But more importantly, that big lion dick was now hers, in a sense. One of her own started forming between her legs, filling out with a squelching noise, accompanied by two plump, smooth nuts that jiggled about as she rocked her hips in pleasure. The delicious sensations of digesting her meal and altering her body alike had her fucking the empty air, hissing with drooly lust as a new, solid xenomorph cock rose up solid and sensitive, trembling just to feel the air passing over it. Such a needy spire was in dire need of someone warm wrapped around it. She just had to find the proper victim to deal with her new needs.

The last few traces of the lion slorshed away while Gusher made her way through the ship's vents once more. She hisses her way along, spreading that aphrodisiac scent all through the ship, distracting those who were hunkered down and those who were stomping about the halls in search of her alike. Many members of the crew were isolated at their posts, ready to respond to any sort of emergency, the doors locked. That wouldn't keep Gusher out. One such crew member was a soft, red-haired leopardess all wrapped up in a skin-tight uniform, sitting there in the nurse's station. She looked sleepy, leaning back on a stool and just waiting. Much like the lion, she probably thought this was all some sort of false alarm, or maybe a drill. Her ID tag read Mahiri - but Gusher only knew her as a delicious-looking thing. The xeno lingered in the vent just above her until she started dripping down on the unaware feline, breaking her from her slumbery state, leaving her slowly looking up.

"Is there some sort of leak ..." she murmured to herself, but quickly drifted off as the scent of that slime started to have its effect on her.

From tense to relaxed, shedding all the tension that came with those blaring alarms, the cat soon melted into a warm, aroused state that had her rumbling without even knowing why. She didn't bother to look up, instead just shifting in her seat, spreading out her thighs and slowly wiggling back and forth as a drenching lust overtook her and flooded her with desire. The effects were far too strong for her to concern herself with where they might have come from. She just knew she needed to get off, and Gusher was more than happy to help her out, with that new endowment of hers. She slopped through the vent and slowly dropped her tail down, letting it curl up on the floor just behind Mahiri, followed by the rest of her. The heavy thud had the leopard spinning around in her chair, left stunned by the sight of what had so easily snuck up on her. If it wasn't for that wafting cloud of thick, sex-laced pheromones, she might have screamed right then, but instead she just sat transfixed by what she was seeing, her emerald-coloured eyes darting up and down the shape of the alien standing before her. And that fat, pulsing xeno dick.

Gusher gave her a few moments to admire that goo-cock before she attacked. Mahiri offered no resistance, squirming with desires as she got knocked down flat to the floor, pinned beneath the bulk of the hissing alien. Even in goo form, the xeno still had some deadly claws, but she put them to careful use stripping the tight clothing from the leopard's curvy body, ensuring she did no harm to the skin beneath. She needed that cat intact if she was going to take all the pleasure she wanted from her. One Mahiri was left wearing nothing but a few last torn rags around her wrists and ankles, her spotty body exposed, soon spattered by the dripping slime of the looming creature. A slap of that thick alien shaft atop the kitty's pussy made the leopard mrawl, and then she was moaning out, crying out in bliss as the alien started grinding. Such good feelings came with simply rubbing her new dick against that slick cunt, sliming it up with a nice azure coating that stained the white fur between Mahiri's thighs. Gusher humped and bucked a while, just getting used to the feeling of using her dick on someone. Instinct and desire alike quickly told her exactly what she needed to do.

Grabbing the cat by the thighs, she soon had her folded up into a cozy U-shape, mounting over her for a proper mating press. It just made the most sense when she wanted to get in deep. First it was a matter of probing those plump pussy lips, skating the tip of her slime-coated cock up and down along those tender folds, taking in the sensations, examining the detail. Soon, the pumping urge to drive deep inside the leopard and breed her until she couldn't think. The alien might not have known exactly how feline anatomy worked, but she knew that cunt felt good all wrapped around the inches of her newly formed goo-dick. A pumping, thrusting, pounding motion made the leopard mrowl in a way Gusher liked, so she leaned down close and hissed right in her face, drooling on her while she fucked the screechy noises right out of that thick-hipped cat. Such curves were perfect for plowing and thumping - and they only served to remind Gusher of just how hungry she really was. A soft, shapely, warm mammal would feel so good sliding down her throat.

The schlorp and plap of that dick plunging out of Mahiri's pussy went along with the splatter of slime spreading across the room, sinking into her fur. She stained the cat's pelt with her goo, stretching from her thighs to her belly to her tits. The steady slap of balls against that pussy rang out right down the hall, that schlicking sound blending smoothly with pleasured hiss emanating from Gusher. She lunged at her prey, jaws coming at Mahiri's face over and over, but the leopard wasn't intimidated. The scent of that slimy creature drove her deeper and deeper into need, leaving her aching for more even while she got dicked hard by that monster, and soon she had the taste of that goo to leave her even hornier. Gusher dipped that toothy tongue down between the leopard's lips, tasting the inside of her mouth, letting Mahiri swallow down that slime until she was utterly hooked on its flavour. She drank it right from the source, sucking that dangerous tongue, leaving her trembling around Gusher's dick, clenching, kneading hard as climax blazed through her thighs.

A pounding, oozing, soaking peak left the leopard silently screaming. All she could do was open her mouth up wide and gasp her way through climax, cumming hard for Gusher, squirting for that amorous alien while those balls pumped hard against her soaking mound. The xeno wasn't far behind. She let that delicious feeling hit her, making her toss her head straight back, jabbing that inner jaw into the air while her balls pumped up tight and churned out a fat cumshot to mate that leopard full. Gusher watched with satisfaction while the kitty's belly swelled up and stretched with all that alien spunk breeding her plump. She might have even been knocked up with some sort of alien offspring, but that was hardly going to matter in a moment, for all the gooey saliva pouring down from Gusher's open jaws. The xeno barely even waited to finish cumming before she lunged, and this time she went all the way.

Mahiri was still twitching and convulsing in the throes of that wild orgasm when she found herself neck-deep in the humid jaws of the alien. Gusher slipped those teeth around the throat of her prey, but she didn't bite. That soft body was going to feel so much better squishing down while. Another thrust of her hips, pounding into the cum-fountain that was the kitty's pussy, sending the overflow splashing to the ground, and she started gulping. A shove of the leopard's head to the back of her throat meant she could catch hold of the cat's face with those powerful inner muscles, dragging her inside along the slime-slick surface of her gullet. Gulping, gripping, she devoured her meal whole with her cock still inside her, only pulling out with a spray of seed when she'd squeezed the leopard's shoulders together inside her jaws. This one went down even smoother than the first. The lion had been so bulky, though satisfying to digest. Mahiri's curves were by contrast pleasingly squishable, so malleable to constrict on with the powerful workings of the xeno's throat. She'd have that leopard in her gut in no time.

Delving down inside the goo-xeno's body meant getting a noseful of that enticing scent, as well as a continuous taste of the very same flavour that had so aroused Mahiri in the first place. She was a writhing, intoxicated mess of a meal slipping into Gusher's body, ready to be digested and absorbed. Her tits made for an ample bulge slipping down the xeno's throat, tucked away and vanishing in the alien's chest as the escaped experiment continued with her meal. This one, she savoured a little more, but it was still a sloppy, slimy devouring, gobbling her down but tasting her along the way. From those fine tits, to that sloshing belly, to that creamed pussy, Gusher made sure to taste and nibble her way along the leopard's curves, framing that spotty ass between her deadly teeth, enjoying that final moment before the last big gulp. Then it was a toss of her head, and she dragged those thick thighs straight down her throat, slurping the cat away like a rumbly noodle, keeping her prey moaning and gasping all the way inside thanks to the generous dose of pheromones blanking out all the usual fear she might have shown in such a situation. To her, it was nothing but bliss, all the way down, even when she found herself all wrapped up snug in the confines of an alien's stomach.

The xeno clacked her teeth with satisfaction as she finished off her second meal, cradling the bulging shape of the cat in her middle. A heft, a squeeze, a deep, kneading massage, and she kept that feline squirming, but it wasn't going to last much longer, for certain. Not with the steady rumbles closing in all around her. That was no purring - it was the looming churn of the transformed creature's hunger overwhelming the living meal, coating her with goo, bathing her in digestive slime that swiftly worked to start absorbing her. Mahiri had already been soft enough, but she was getting softer with every heavy glurrrrn. Gusher simply sat herself back, left with the locked medbay all to herself while she digested their cute nurse whole, taking from her everything she needed to sustain herself, and the genetic code that helped to change her shape even more. She was changing again. Taking more and more from her prey meant enhancing her natural xenomorph shape with assets more similar to the mammals she'd been digesting. The more Mahiri softened and smoothed over in that bulging goo-gut, the bigger Gusher's new bust became, swelling out with a great big pair of sleek, shiny tits much like those of the curvy cat she'd just consumed.

Of course she had to play with those new breasts of hers. They were soft and squishy, bringing her enough pleasure when she squeezed them that she hissed sharply, her dick throbbing again, even while it dripped the remnants of her last cumshot. Plenty of the leopard's own juices were clinging to those inches too, but that was about the last sign of the cat. The shape of her body was indistinct by then, just a rounded bulge that grew smaller with each noisy churn. By the heavy, glurking noise echoing out from Gusher's middle, it sounded awfully messy, but she was simply being converted, transformed, and absorbed, in turn. Every last trace of her ended up a part of that slime-coated creature, down to the very bones. She vanished from existence and left the alien playing with a plump new pair of tits, and soon after smacking together a thick pair of lips that helped conceal her frightful fangs a little better. That was another trait she stole from her prey, though hers ended up even thicker, fuller, a juicy pair that she couldn't wait to use on someone. The only challenge was for her to stop admiring her newly added curves and instead leap up into the vents to continue pursuit of prey. Her appetite was hardly sated even after digesting the entirety of two unlucky cats.

In her wake, the slime was growing. It started as simply a trail, but it spread outwards to grow thicker, carpeting the halls she'd stepped in, or even those places she'd merely graced with her presence as she scurried through the vents above. A few trickles was enough to spread that gooey corruption through the ship, until it completely coated some rooms, burbling and splorching with apparent life. It was that observation that so compelled Milky. The naga researcher noticed the pool spreading beneath her door, making her flick her tongue and catch those curious pheromones. Scientific fascination immediately took over, as well as plenty of lust, leaving her slithering on over to examine the substance in clear breach of contamination protocols. She simply had to get closer, had to touch, even to lick. Soon she was tasting that slime for herself with a little swipe of her forked tongue, and she hissed much like the xeno herself as the flavour brought her such indescribable pleasure. Suddenly, she cared less for studying it and more for further exploring the divine sensations such a mysterious substance could bring her. The only thing that could distract her from her purpose was the clamour just outside her door, the sound of several distorted voices working together in panicked unison.

"I can't move!"

"Just fight against it!"

"We should burn our way out!"

"What, are you crazy? We'll go up with it!"

"I can't breathe ... I need to take off my helmet ..."

"Don't you even think about -!"

Then there came the sound of rushing air, followed by some sort of splorch and a muffled cry. Milky knew she was supposed to remain in her chambers, but she had to see, she had to know more about the strange phenomenon that was taking over the ship. Opening the door, she saw one of the security teams rooted in place in the middle of the room, a large lounge near the sleeping quarters. Their boots were stuck in the room-wide goo, and one of them, a fox fellow, was flat on his back in the middle of it. It was hard to even tell who he was, given the presence of something writhing there atop his face. She knew of facehuggers, but this one was different. For one, it seemed to be coated, or perhaps made entirely of that thick blue goo that had taken over the room. And for another, it wasn't simply latching on and passively impregnating its chosen mate, but instead was rocking, rutting, and fucking that fox's mouth roughly, plunging its goo-dick straight down his throat and pumping in its thick, slimy seed.

The security team was hardly panicking, either. Instead, they were following suit, slowly unsealing their helmets and removing them, looks of awe and lust on their faces. Milky got a brief glimpse of their faces - that of a heavyset polar bear and a handsome dragon fellow, before they got their turn. As from nothing, two more of those huggers leapt up from the goo below, encircling their heads with those thin limbs, latching on tight and sticking those alien dicks all the way down their prey's throats. The security team was soon all sprawled out in the goo, getting fucked hard by those small creatures, left writhing in apparent pleasure on the floor. By the bulges in their uniforms, it certainly felt good. Milky herself felt arousal hitting her at the sight, her mind blanking out to instead leave her slithering out to join them. Her own personal facefucker found her soon enough, dousing her senses in those delicious flavours as it leapt up from below, tackling her right down to the slimy ground, penetrating her on the way. She was left sprawled out and paralyzed by pleasure, wanting nothing more than to moan if simply to show the alien her appreciation, but she couldn't move a muscle. She was just going to have to wait until it was done, that slime-dick plunging into her throat again and again, sharing a flavour so intense her eyes were rolling back in her head.

If those were ordinary facehuggers, she might have been in some serious trouble. But rather than being turned into a living incubator for some new xenos, something much more wondrous was happening. She felt orgasm hitting her hard, leaving her squirting over her lower coils even while she was totally unable to move. Her body felt as if it was sinking, slipping down into the slime as it completely overtook her, immersing her in scent and taste, nearly drowning her in that intensely arousing warmth that came with that unnatural slime. There was just enough of her mind left to consider that the experimental substance had shown a unique interaction with the xenomorph's physiology, but after that, all was dark. Thought gave way to pure instinct as her body began to change, her scales growing smooth and sleek, her curves made harsher, more angular as she morphed into one of the very creatures she'd been studying. Longer limbs, a curved spine, and a long, agile tail, she was left sputtering as the facehugger finally released from her, sinking back into the slime, leaving her to rise up and be rebirthed as one of the escaped xeno's new scouts. Cum dribbled from her slavering jaws, mixing with the saliva that spattered out as she gave a testing jab of her new inner jaw, that deadly mouth-tongue snapping forth and retracting back with a satisfying feeling. A glance up revealed the fate of the security team had been the same. Their uniforms lay in shreds around them, their weapons discarded, three slavering xenomorph scouts standing tall and ready to serve Gusher without a second thought, her will extending to their own, as if connecting through the slime that had shaped them.

The first order of business was to find more prey for their new mistress, of sorts. They took off into the ship, their new claws clacking on the floor as they went. Milky found herself quickly adjusting to her new form, running on two legs as if she'd had them all along, forming a pack of sorts with the other transformed crew members. They knew only their service to the hive, and lacking one of those, Gusher served well as their leader, for the time being. All it took was a simple ambush, a pounce from the shadows and they soon had their hands on another pair, choosing two thick and meaty specimens as their offering to the goo-xeno. Meesha and Tiki, a brown hyena and a blue macaw, couldn't do much to resist the aggression of those aliens, taken completely by surprise and caught up in those flexible tails, coiled up and carried off. They struggled at first, crying out in terror, but that all changed when they entered that thoroughly-gooed room. Just one huff was enough to soothe the senses, to melt away the panic and quell those worries. All they knew was the dull, horny haze that came over them, leaving the bird a little wet, and the hyena bulging in her uniform.

Gusher meanwhile was waiting for them. She didn't even need to communicate directly to sense what they were up to. Perhaps it was the goo that kept them connected. Such ponderings were for the scientists, and she planned to devour those. Her hunger was endless, but so was her lust, leaving her dick thumping up against her thickened belly, a bit of pudge added to her form thanks to those two cat's she'd eaten. Yet she still wanted more, refusing to stop, especially when she caught the scent of fresh prey getting dragged in. Her scouts deposited those two captives at her feet once they found her in the medbay, leaving them splatting down into the slime that waited for them below. By then, those aphrodisiacs had already infiltrated their senses to the point of numbness, dumbness, and subservient arousal. They weren't even shaken to look up at the goo-xeno looming over them. Tiki offered a great big beaky grin, and even the timid hyena was wearing a soft, horny smile, slowly swishing her tail as the escaped experiment took her time in considering which of them to eat first.

She'd been smacking and puckering those new lips of hers ever since she'd first developed them. The urge to feel them wrapped around someone was simply too tempting. She nodded to her scouts, who stripped down that curvy bird for her, leaving a few feathers flying in the process but leaving her unharmed. Then it was time to snatch her up. She grabbed Tiki beneath the arms and pulled her into the air, leaving her to dangle and sway in front of those drooling jaws. Gusher parted her new lips with a wet little pop, revealing the strings of spit and slime stretching between them, clinging to those sharp teeth that soon framed the entirety of the macaw's vision. Her body stiffened at first, but swiftly relaxing, far too turned on to do anything but accept what was happening to her. Gusher wrapped that soft bird up snug, pointing that beak to the back of her slippery throat, but not swallowing just yet. She had to put those lips to use first, and that involved the messiest, noisier sucking she could possibly muster.

Pressing her teeth around the bird's throat but refraining from biting, Gusher used those lips to the fullest, kneading down on her meal while she suckled Tiki's entire head, utterly bathing her in slimy drool in the process. Oh, it felt good to slip her between those plump lips, and the xeno soon needed more, shoving at her prey, planting those lips on those fine tits. Tiki's legs were faintly flailing about, not exactly struggling, just twitching in pleasure while she got her body sucked, shoulders easily popping past those lips, the slathering inner jaw working like any other tongue, soaked and smearing spit across those feathers, matting them down with dampness. The strokes across her tits were enough to make her moan and chirp, the sound echoing down the humid cavern spread out before her. The first gulp muffled those, slurking her into the alien's depths, but Gusher was hardly devouring her just yet. Instead, she inched along the bird's body, slobbering upon every feather, sucking on her like she was little more than a sweet piece of candy. Tiki's upper half bobbed back and forth between the xeno's new lips, massaged by them with every suck, dripping with lust before she even got so much as a touch to her wet pussy. Gusher licked that soon enough, using that second mouth to gingerly nibble around the puffy folds of that fine sex, taking a few licks and tastes as well. The further she fed that bird into her gullet, the wetter things became, pouring down all over Tiki's head until she was all but submerged in all the juices Gusher was working up in the process of sucking on her.

That just meant it was getting noisier for her too, the steady schluck schluck schluck occasionally interrupted by a massive squelch as excess slime poured from the xeno's jaws, trickling along the macaw's thighs, dribbling from the tips of her toes. Gusher swallowed a little more, and a little more, revelling in the way her new lips let her savour her prey in ways she never would have imagined before. But eventually, she had to finish her meal. She'd nearly sucked all the flavour out of that poor sopping bird. At least the outside. There was still plenty to sample once she plunged that tongue inside Tiki's pussy, fucking her with the powerful thrusts of that second mouth a few times, being careful not to overdo it. From moans to shrill, inelegant squeaks deep down in Gusher's gullet, Tiki made it clear what she thought of that. She was writhing, kicking, wriggling like mad between the xeno's gooey lips, and her legs soon went stiff with the squirting orgasm that rocked through her, overwhelming her entire body, leaving her erupting with juices that Gusher simply guzzled down in the process of consuming her. They were the lube for her own consumption, not that the xeno's gullet needed to be any more slippery.

One long, extended slurp, squeezing those lips down all around her meal, and Gusher finished off the tasty bird as slickly as possible. It made such an excess of noise that it seemed to echo through the room. It was all having such a strange effect on the horny hyena below, her usual horror suppressed even as she watched the curvy bulge of the consumed bird sliding down to thump into the alien's belly. That outline was so tightly hugged by the contracting walls that she could make out most of the details, right down to the bird's expression of glazed-over awe and pleasure. The slimy digestion process didn't disturb Tiki's contentment, keeping her intoxicated and moaning, thrusting, bucking, rolling her hips as she rubbed herself off even while she was getting melted down into alien pudge. The heavy gurgling filled the room, partly drowning out the lusty hisses emanating from the xeno. She was done with one meal, and it was time for another. Meesha didn't get a chance for a second thought before Gusher lunged again, grabbing her by the shoulders, squeezing that soft, chubby form of hers in a two-handed grip while her cock pushed up against her cushy belly, throbbing away. It was nowhere near as big as the xeno's own, something she soon got to see for herself.

It just made sense to Gusher. That new dick of hers was thick, flexible, and it ached with what felt almost like hunger. So of course she was going to feed it. That involved shoving the hyena face-first into that gaping slit, letting it slurp down her muzzle and grip around her whole face at once. That meant Meesha was getting a direct dose of some of the most potent of those slime-pheromones. She was swiftly blanked out, rendered so horny she ended up cumming on the spot. There was no build up, no anticipation, she just squirted from the scent alone, spraying a load of jizz at Gusher's feet as if in tribute. It didn't make her any softer, either. She was just as hard as ever even after pumping out a fat enough load to leave a puddle on the floor, steaming hot but no hotter than the sweltering confines of the xeno's clamping dick, clamping and tugging all around her head, dragging her closer to the musky depths that churned for. Gusher's nuts were every bit as hungry as her gut, churning just as loudly with need as the grumbles and glorps that rumbled out from the xeno's bulging middle. The bird was already softened, already absorbing, and Gusher's tits and were already getting thicker and heavier. So too were her lips, despite her beaky meal. Maybe it was just the feminine nature of her prey that worked well enough to feed her transformed body. She didn't care as long as it worked.

A sloppy ULP around her prey sounded just like the workings of her throat. Her cock was hungry, dragging that squishy hyena inside with tremendous clamping force, pressing down on all those soft curves so tightly they were a skintight outline beneath the surface of that slime-coated cock. A slurp, a squeeze, and she gobbled that chubby mammal right up, enjoying the feeling of all that fluff rubbing its way down her dick. Working over those fat tits into her fat dick made sure such a pretty bulge, one she was soon rubbing with one hand to help the process along. Every pulsing throb of her shaft fed that tasty girl deeper down towards her balls, until Meesha's muzzle was splashing into the thick spunk that awaited her. The taste and scent combined to leave her nearly numb to pleasure, unable to feel any better than she already did. She curled her toes, swished her tail, and came a long rope of jizz down that consuming spire, her orgasm leaving her twitching and writhing all over, even as the xeno's dick enveloped that big butt in the snakelike constricting grip that gobbled her down so slickly and efficiently. Soon there was nothing more than a pair of juicy thighs sticking out of Gusher's bulging shaft, leaving her to rub herself off with both hands, dragging her prey into her sack so that she could churn her up like the bird.

Tiki was softened to the point of barely recognizable, thoroughly gooed and absorbing into those tits, leaving them several cup sizes larger than when Gusher first swallowed her. The xeno played with her prey-stuffed balls, trapping the hyena in the middle of them, letting her slosh in the spunk-filled chamber while that seed churned all around her. It splashed and soaked and drenched her from head to toe while she was all curled up in there, bathing in the intense heat and scent alike. Her mouth remained open, tongue flopped out so she could cash any of that seed that might have splashed over her face, drinking it down while she basked in the idle intoxicating of the xeno's scent and taste. Her cock remained firm, bumping against her belly with its throbs. The churning of those nuts around her didn't break her out of that stupor either. She was content to lie back and let herself be claimed by the oozing slime and spunk sinking into her skin, marking her with that potent essence, kneading her into a softer state with each squeeze of those tight walls around her confined curves.

Gusher worked herself up into a hissing fury, fucking her grip wildly while her scouts patiently waited for her to finish with her prey, drooling at the sight. Milky had no memory of her former self anymore. She was part of the xenos and always had been, as far as she knew. The sight of that great big goo-xeno digesting another victim and turning her into added heft and girth on that fat alien cock was worthy of praise and worship, but she was just going to have to serve in other ways. Gusher jerked and stroked and kneaded herself, softening the shape of the chubby creature in her balls, squeezing down hard on Meesha's outline until it became less and less distinct. She was losing her colour too, as if getting all washed out of her fur, bleaching her as she got processed into a nut-stuffing load of spunk that soon rose up over her head to swell and stretch the xeno's balls. There was no fear of drowning. She wasn't going to last much longer with her silhouette already blending into the jizz that flooded Gusher's sack, losing feeling while the xeno madly stroked her way to a climax that had her shrieking loud enough they could hear it throughout much of the ship, nestled into their hiding places.

A tight clench of the xeno's sleek balls made them perfectly round for those few churning seconds before climax, completely smoothing out any last solid trace of Meesha while her shaft bulged with how much spunk was rushing through it. It swelled out, stretched, and finally erupted with enough force to send Gusher's hips recoiling from the blast. She sprayed that churned up prey all over her scouts, and the rest of the room, bathing them in her scent and her pheromones, ensuring they stayed nothing but loyal to her as they watched her spurt out gallons of cream at once. That hefty hyena was nothing more than an oozing flood of alien jizz, and some added girth to the xeno's dick, extra weight and to her balls, just as Tiki had added to her curves. When she was finished hosing down her surroundings in hot xeno seed, Gusher took a moment to admire the shape of her body. She'd taken on such a feminine shape, enhancing those curves, those thighs, those tits thanks to all the crew members she'd digested just to feed her appetite. She was slicker, gooier, but even after coating the walls with her cum, she was still too horny to relax. Maybe less hungry. For the moment. There were plenty of crew left in their hiding places, when her appetites awoke again. No, the next urge she had was to find a proper mate, someone she could turn into a proper breeder queen instead of simply devouring. And she could think of no one better to sate those urges than the one who had started it all.

Her scouts knew her needs without her needing any knowledge of their language. She didn't speak her commands, she simply felt them, and they picked up on that impulse, vanishing into the ship once more to retrieve the hidden valoinx. They snuck about the ship, finding other crew members either caught up in the lust that wafted from those slime trails, or pinned down by those facefucking huggers converting them to yet more members of the scout team. Those, they ignored. They had one target and only one target, at least for the time being. There were plenty of hiding places on that small ship, crevices and other spots to slip into and wait for everything to blow over, hoping the security team would take care of things. Of course, the security team was part of the pack that was hunting them down right that very moment. Rescue wasn't coming. The xenos picked their way through rooms, checking under beds, in lockers, or closets. Sometimes they stumbled upon other people hiding here and there, but they ignored them, politely closing the door right back up again and leaving them behind, stunned and confused.

Sienna was pretty sure it was over by then. Sure, the alarms were still going, but she didn't hear anyone running around anymore. Everything was silent enough that she couldn't help but poke her head out from beneath the bed she was hiding under - though she was more thinking about avoiding being caught near the accident, rather than what she'd unleashed. She hadn't even had a good look at the xenos, left really with no idea of how bad things were getting on the ship. Peering out, she scanned through the quiet employee sleeping chambers, seeing no one else out there. She could see the warning lights in the hall blinking beneath the door. It was a little unsettling, for sure. Eventually, she found herself just too anxious to stay silent, softly calling out into the silence.

"Um. Is anyone there? Is it okay to come out now? Did we pass the drill?"

It wouldn't have been the first time. The corp was always so strict about making those kinds of things as realistic as possible, even if it spread panic among the crew. She slowly crawled her way out of her hiding spot, moving towards the door, but before she opened it, she stopped to listen. Yes, those did sound like footsteps, thumping down the hall and echoing. They were getting closer, moving swiftly, some sort of scrape and click-clack sound coming right with them. Maybe that was just the team coming to tell her everything was fine. She slowly opened the door, her heart suddenly pounding for whatever reason. One glance down the hall revealed the sleek and shiny forms of those scouting xenos, leaving her blood running cold, freezing her to the spot with a soft gasp. That one sound was enough to make them turn their heads and fixate on her in a moment, and they didn't even hesitate to charge.

Sienna got as far as letting out a little eep before they were upon her. A flash of teeth and claws convinced her it was the end for her, but they were surprisingly gentle with her as they picked her up and carried her between them, easily hauling her weight like it was nothing. She didn't bother to scream or struggle. It was already plenty obvious she wasn't getting away. Instead, she just stared up at those strange creatures with a certain sense of fascination. And maybe a little lust. They might not have been made of goo, but there was still plenty of that scent clinging to the four of them, ensuring Sienna slowly got more and more aroused as they brought their captive to Gusher herself. One hall and another, on and on, until they reached the medical ward where their leader was waiting. Sienna's response was to stare with something like rapture, opening her mouth simply to drool. The xeno's goo-scent had grown thicker and thicker, marking down that room in the hot, horny aroma that left her absolutely aching to be taken by that monstrous creature, pushing aside all the fear she'd been experiencing mere moments ago.

Gusher circled her for a time, streaking slime around the room as she hissed and leaned in close to the valoinx, reaching in to touch her and stroke her with those claws, handling her gently. Even the process of stripping her down was a slow one, working her clothes off, tearing them when necessary, leaving her purple fur on display. She was left sprawled out on her back, gazing up at the drooling xeno, feeling her body urging her on, aching, begging to be bred the longer she remained immersed in that breathable aphrodisiac. Her pussy was soaking wet in seconds, and she found herself sucking long, deep gulps of air just to get the most of that xeno's scent. Gusher took her by the wrists and stretched her out, laying that slimy form overtop of her and pinning her down. The goo-xeno didn't need to be forceful. She'd already broken her captive into her willing servant with her wafting aroma alone. Even better was her taste.

A smearing schlorp of that prey-enhanced cock across Sienna's body marked her fur down with those deep slime stains that felt so very tantalizing just sinking into her fur. Even better was when Gusher pushed her cock up towards the valoinx's face, grinding from cheek to cheek, sliding across her lips, urging her to latch on and drain that taste for herself. The flavour ignited all sorts of pleasure receptors in Sienna's mind when she took her first lick, followed by a kiss. Of course she needed more. Opening wide, she stretched her jaws around that girth to goofully go down on Gusher, sucking the slime right off that shaft and swallowing it in bliss. She moaned around the inches stuffed into her, letting them bulge in her neck, outlined as she kneaded and gulped around as much as she could fit at once. Closing her eyes, she focused on the scent and flavour bombarding her senses, that overwhelmingly potent goo essence that kept her dripping, kept her clenching with desire while she sucked the xeno's cock. The act was reward enough, but what made it even better were those satisfied hisses coming from the alien herself. Sienna was doing a good job. She wanted to prove she could please such a creature.

Without questioning how the monster had come to be, Sienna found herself completely devoted to pleasuring the alien, to being the best little broodslut she could be. Some part of her already knew how this was all going to end. Her body ached to be bred, and the xeno's dick throbbed between her lips, filling her belly with that potent slime. She could already feel it swirling around inside her, having all sorts of effects on her she couldn't begin to understand. Gusher let her knead and suckle that shaft for a while, but eventually her own monstrous need took over. She started thrusting, plunging into the valoinx's throat, pumping, fucking her face like she were one of those facehuggers. Soon Sienna had a pair of slick balls slapping her chin as the alien bottomed out in her mouth, and yet somehow she never found herself choking or aching for air. Maybe she'd already been transformed a little bit, on the inside, just enough to serve the xeno for all her needs.

A tit-bouncing, chin-slapping, hissing, drooling frenzy soon overtook Gusher as she fucked that throat again and again, filling her prey with slime and soon going rigid, solid, twitching there between Sienna's lips. The valoinx knew what was coming, bracing herself as best she could. The xeno came hard for her, all thanks to those sloppy sucks, and that smooth, warm throat of hers. The first rope gushed straight down to the bottom of her belly, already swelling her, already bloating, filling, stretching. Some of it came rushing back up her throat when she couldn't handle the sheer volume of alien spunk shooting into her body. She didn't cough. She refused to stop sucking even as the xeno went off hard, jizz pouring down her chin and over her tits, leaving her guzzling as much as she could and wearing the rest. A splatter of seed poured across her body, oozing towards the floor, puddling out around her, soaking right into her skin to ensure she was thoroughly marked with the essence of the monstrous beast who'd just fucked her face. And Gusher was far from done with her.

A clutch of Sienna's hips made her flip over so the xeno could mount her from behind. Gusher got up under that tail and slipped her fat cock between her thighs, fucking those at first, grinding between her legs. She hadn't softened in the slightest. That slime-cock was smeared with cum, painting it over Sienna's fur until she pressed up and found her pussy. Sienna could only dip her head down as the xeno pinned her, clutching her by the fur and the left tit while she pinned her with all that beastly weight. Then a smooth, deep penetrating, delving deep inside her and stuffing her with that xeno dick, stretching her out snugly and overwhelming her with warmth. A schlick and a plap and Gusher bottomed out, stretching Sienna to her fullest, yet doing her no harm. It didn't hurt in the slightest, even with a plump cock bulging in her slightly sloshing belly. She could still feel the weight of all that cum inside her, and the slime too. It was doing things to her. Wonderful things. Her body tingled all over as the xeno slapped her thighs with those huge nuts, driving pleasure into her that was only amplified and multiplied by the overdose of aphrodisiacs she was getting with every gasp. Even while the xeno fucked her, she was still desperately horny, wanting everything Gusher could possibly give.

"Yessss ... urgle ... god, it's ... urk ..."

She couldn't do much to dirty-talk the xeno when she was still drooling and gargling cum. Muffled moaning was just going to have to do the trick. Her voice sounded familiar at first, but it was growing more and more like Gusher's own while that alien went to town on her pussy, pounding it nearly numb. It wasn't exactly a romantic lovemaking. They were mating like monsters, wild creatures, and every thrust was driving Sienna deeper into some sort of deep-rooted instinct she never knew she had. Or maybe she was changing, somehow. She wasn't thinking about in the middle of that smacking, schlurking, messy alien sex. With her eyes closed and her jaws hanging wide open, she drooled her way into a silly smile, fucked dumb in minutes and only getting dumber, blanking out in favour of pure, concentrated pleasure. Why was she there in the first place? A ship? A secret project? Working as a janitor? That felt like nothing more than a dream. Right there, on her knees, bent over and bred by the gooey xenomorph, was the only thing that mattered to her anymore.

Her body jiggled back and forth with every thrust, making her tits wobble right along with Gusher's own. Sienna had no idea of the ravenousness that helped shape that slimy figure, the feminine curves she'd absorbed from her meals, the girth that grew thicker thanks to her feasts. That steady thumping did well enough to keep her focused solely on the pleasure, on the aching need that surged through her every single nerve. Clamping down tight on that cock showed the xeno just how close she was getting to climax. She wouldn't even just passively take that rutting, soon thrusting herself back, smacking her ass into Gusher's underside just to take that dick deeper, fucking her way to that perfect release they both so badly needed. Her pussy tightened up. Gusher's cock stiffened, her balls went rigid and taut, churning up another massive load that swelled them to brimming. The blazing heat between Sienna's thighs told her she was about to find out what it felt like to get knocked up by something so far outside her species, outside all the worlds she'd ever known. And she was nothing but ready for it, hands planted firm, back arched, tail up as she offered herself to the slime-coated beast.

The rush of hot spunk brought her immediate relief, as if dousing a fire inside her. She squeezed, she contracted, wildly twitching around the xeno's inches, and then she squirted hard for Gusher, pouring it all out, hosing down her own thighs while the alien filled her with seed. The sensation of it taking was immediate. No delay, no waiting to test if she was really pregnant. Her body began the immediate process of transforming into the breeder queen she felt she was always supposed to be. Her breasts swelled right along with her belly. Her thighs thickened, her ass got softer and heavier. And as if from her very pores, that slime began to ooze all over her, coating her skin and fur, giving her a new layer as if overtaking her with a wet, shiny bodysuit. She was left drooling in delight as she rocketed through that orgasm, feeling her jaws stretching wider and wider, gaping with their new depth, lined with longer, deadlier teeth. That xeno fucked her right into something else, and she just kept going, kept thrusting into her even in the middle of that squirting climax, absolutely ensuring that alien breeding was going to work perfectly.

Sienna's belly rounded out, maybe with eggs, maybe just with cum, the rest of her swelling as she grew, stretched, changed right there beneath the goo-xeno, her body transforming with that cock still shoved deep inside her. From valoinx to something more like Gusher herself, covered in slime, toothy, monstrous, flashing dangerous claws and fangs alike as she hissed and screeched in her newfound voice. But it went even further than that. She wasn't just becoming another xeno. She was getting bigger, stronger while her pussy gushed the excess juices of their strange courtship. Gusher pulled out to cum on the back of the former valoinx. Sienna was something else now. Thicker. Hornier. Swelling up to a rounded state, with a heavy belly beneath two massive tits. Her pussy blazed with need once more as she rose up from beneath the xeno, cracking her back and flicking her new, toothy tongue. Her every sense felt so much sharper, like a true predator, a hunter. But all she could think about was breeding as she towered over Gusher, cum pouring from her cunt and down her newly gooey thighs. There were plenty of mirrors around the medical ward. She loved what she saw.

Not just a xeno, but a queen, a breeder queen at that, already swollen and gravid with young, or something else. She had no idea how her new body worked, but she knew that it felt right. Tipping her angled head towards the ceiling, she gave a frightful scream as she embraced the new life Gusher had given her. No more cleaning jobs, no more fussing about credits. Simply breeding, over and over, delighting in it every single time but always wanting more. Even after getting so thoroughly creamed by the goo-xeno, she was already burning for more, already swishing that long tail of hers and crouching down to get on Gusher's level. She was going to need everything that lusty xeno could give her, and more. The transformed scouts slowly closed in on her as she waited, dripping, oozing, sliming up her surroundings with the thick tendrils of lust pouring from her pussy. Seemed she was going to have a loyal hive tending to her every need, soon enough. Together, isolated out there on that science vessel, with nobody able to send out any sort of message of distress, they were going to feast, and fuck, until they bred themselves an army.
