Chapter Text
This mission had been a bad idea from the start- not that he or the rest of his squad had a choice. Weylan-Yutani said ‘jump’, and grunts like him didn’t even get to ask ‘how high’- they just jumped, into shitholes and suicide missions like this.
He wished he could’ve been surprised his life was going to end this way, in some deep, dark tunnel on an asteroid in the asscrack of the galaxy. But it was always going to go this way, sooner or later.
Still, he had watched with dread as the life signs of his squad dropped off the radar one by one- before long, his own signal pulsed, all alone, on the grid. That was when he realized he wasn’t getting out of this one.
The cavern was a hellhole in a category all its own- it moved occasionally, vague seismic rumbles that shook the ground beneath him, and geysers of gas erupted from below. Several times already, he’d barely escaped a quick, scalding death in its craters.
Somewhere in this chaos, he’d lost his weapon, and the uneven terrain, the inky, thick darkness of the walls around him, made it impossible to spot. He swept his lamp across the ground desperately, seeking the reassuring glint of metal, but the wet ground reflected the light and only gave him false hope.
The hair on the back of his neck stood on end, the sudden feeling of being watched overtaking him, and his search became all the more frantic, the weak beam of light wavering as his hands began to shake. Something moved at the edge of his vision, and he cast the light in a panicked circle- what was that?
There was a chittering noise, an ear-piercing screech from the darkness, and suddenly something was thrown directly at his face. The force of the pounce sent him backwards into a wall, back contacting roughly with its jagged surface- he gasped in pain, before focusing on his attacker. It was moving, spindly legs grasping at his head and pulling itself flush against his face- some alien creature, nothing he’d ever seen or been briefed on.
He’d lost the lamp when he hit the wall, and missed its hard metal in his grasp, even as nothing more than a makeshift weapon against the ambush. His dull fingernails scrabbled uselessly against the carapace of the creature, but couldn’t find a grip.
Something prodded at his lips- something slick and fleshy, emerging from the creature’s body. His teeth closed instinctively, bared in a grimace, but the creature forced past them almost effortlessly, wrenching his mouth wide around its organ and shoving it deep into his throat.
He gagged, throat convulsing and bile rising in his gut- tears began to form at the edges of his blinded eyes. His knees weakened, couldn’t hold him up any longer, and he sank to the ground, hunching over himself on all fours instinctively, as if he could vomit the thing out.
Something swelled at the base of the organ, locking into place behind his teeth and filling his mouth entirely. He could not bite the creature, could not even force his mouth closed again- the obstruction in his mouth was far too wide, too strong for that, and he choked around it.
He arched his back, took hold of the creature’s body in both hands, tried to force it off his face, out of his mouth, but it didn’t budge, some unholy strength in it preventing him from even getting a finger between its mass and his skin.
That fleshy knob in his mouth was unyielding behind his teeth, and he could feel its legs grasping around his head, pulling tight at the back of his skull, dragging the body close against him. The sensation was disturbingly like strong, thin fingers running through his hair.
The body of the creature pressed ever closer to his face, its organ shoving violently at the back of his throat, and he couldn’t help but gag again, body trying desperately to reject the intrusion.
The tail of the creature wound tight around his throat, constricting painfully- he felt his windpipe closing, the obstruction of the creature’s organ in his mouth preventing any air from getting through. He began to panic, what little breath he had left hitching in his lungs. He lost balance, fell onto his back, his legs left clumsily under his body as he struggled, bucking and writhing.
His hands immediately, instinctively wrapped around the tail, helplessly pulling at it in a futile effort to dislodge the thing. He noticed half-hysterically that he could feel the bulk of the creature’s organ, feel its mass distending his throat, from the outside.
His suit did nothing to help, only further restricting his breathing with its tightness against his skin, and in desperation, he loosened his grip on the creature’s tail, fisted his hands into the collar of the undersuit instead, and ripped, tearing it open across his chest.
It was little help, but seemed to startle the creature enough to loosen its tail around his throat, just enough to drive the black spots from his mind. He immediately slipped his thumbs under the thick coils- his hands may be immobile now, another way the thing had trapped him, but it left him air enough to breathe, at least.
The air was frigid on his skin, and he could feel it viscerally- every goosebump that rose on his heaving chest made him shiver, the sweat cooling on his skin only heightening the sensation. His nipples tightened and ached with the cold.
He could feel the creature’s organ forcing its way further down his throat- there was nothing he could do to stop its descent, and even trying to cough or swallow around it only hurt.
Through the haze of panic and utter wrongness, he barely noticed a skittering weight across his legs, and bucked as the realization took hold- fuck, there were more. He writhed in an attempt to drive it back, blindly kicking out.
The second creature mounted his chest, its pointed legs digging into his skin. It rested there a moment, and he realized too late that tearing the suit had been a mistake, as it had only revealed more of his vulnerable body to these things. He twisted, trying to throw it off, but it held, flattening itself to him and riding out the motion- those claws sat threateningly atop his vital organs, his soft, unprotected flesh.
He froze, heart stilling as he realized how easily the thing could kill him, could sink its claws into him and rip him apart. The creature released once he was still, moving once more, and he forced himself to remain unmoving despite the creeping dread filling him.
The muscles of his stomach quivered as those spider-like legs tapped lightly across his skin, the contact triggering sensitive nerves and making him shudder. The claws caught at the ragged edges of his bodysuit, tearing the thing further. The creature chittered dangerously, apparently disliking the obstruction- it flattened itself once more to his body, sliding long, thin legs underneath where the bodysuit clung to his clammy, sweat-slick skin.
Fuck, it was going under, inside his suit! He squirmed once more, desperately trying to dissuade the creature from its goals, but to no avail- it dragged itself along his skin, and where it went, the suit tore further with it, the thin fabric ending shredded across him and his chest fully bare. It continued down, his suit tearing like so much tissue paper under the claws of the creature, and his body increasingly on display to the darkened cavern.
Finally, he lay exposed- his bodysuit no more than rags clinging to his arms and legs, the core of him fully bare to the chilled air. The sensation stirred his cock, the skin of his nethers tightening as goosebumps crossed him in waves. And that creature was much too close to his most vulnerable places.
He bucked from the ground, lifting his back- panic had once more overtaken him. He was no human then, only some animal thing operating on instinct, on desperate need to survive, to not be trapped in this way. The creature would not be deterred, and clung to him tightly, sharp claws digging into the meat of his thighs and asscheeks, dragging across his groin.
Something slick and soft followed the touch of the creature’s claws on his skin, and he had the sudden, horrible realization- it was looking for another orifice, somewhere to insert its own organ. Please, no.
He braced his feet against the ground, locking his legs together firmly. But it moved forward relentlessly, pushing against his efforts with its own legs and insect-like body. His strength was not enough, muscles straining against the creature’s power even as it pried him open easily, spread his legs wide as if he hadn’t even tried to stop it, and settled heavily atop the vulnerable flesh between.
It was a brand new sort of helplessness, one he had no experience with. Some kind of fearful oblivion tinged his thoughts, holding onto the back of his mind- he really wasn’t strong enough to fight back against these things, was he?
The creature stationed itself resolutely between his quivering legs, and he could feel its organ- no doubt the exact same one forced down his throat- tracing wetly along his perineum, searching. It found his hole quickly, and steadily forced its way in- it was not quick and sharp, but agonizingly slow, determined.
He whimpered around the mass in his mouth at the violation, blinded eyes screwing shut. The creature settled its organ into him deeply, body pressed obscenely between his legs as it dug further into his gut.
The creature’s tail dragged between his asscheeks, searching for somewhere to anchor. It eventually grasped around his left thigh, high up on the thin, sensitive flesh of it- the sharp tip of the tail pressed threateningly against his scrotum as it moved.
He could feel the organ shoving in ruthlessly, that thick, mucus-like slick only taking the edge off the sharp pain of entrance. It explored his insides, twisting this way and that to follow where they led, and he shook uncontrollably under it, the mental and physical burden of the experience becoming too much to bear. This couldn’t be real, this couldn’t be happening-
The organ brushed clumsily against his prostate and he jerked uselessly, body shuddering as if shocked by a live wire. The creature grasped to him closer, sealing its body to his firmly with its long legs scraping at his hips and asscheeks.
The thing began to swell, locking into place inside him- the knob of flesh pressed against his hole, caught firmly within his body. The creature pushed forwards once more with a demonic strength and that knob was suddenly in direct, savage contact with his prostate, held firmly and not letting up.
He tried to scream around the creature in his mouth, the sensation too much, far too much, oh god he was going to die, shaking to pieces with these creatures atop and inside him! It seemed neverending, the mixed pleasure-pain like a new death every second, and he thrashed under the force of it.
The creature stretched out its tail, wound the tip around his weeping cock, and he felt he must be in hell. These things were toying with him- they knew, somehow, exactly what they were doing to him.
The coil tightened, his cock filling out to uncomfortable hardness in the grip, and he wished he could cry out, only managing a pitiable mewl.
The obstruction in his throat continued its journey downward, painfully bringing his attention back to the creature clasped to his face- his jaw ached being held open, his lips had long gone numb with the stretch, and his face was slick with his saliva and tears, alongside whatever fluids the creature extruded.
There were no nerve endings as far down into him as the organ extended, but he could feel his throat burning all the same, some dense, unnatural heaviness in his lower esophagus.
An attempt to swallow only led the edges of his throat to click around the creature’s organ, seemingly forcing it ever deeper. He could no longer tell just how far the organ ventured inside him, only that it was much too deep- there was an ominous weight in his gut, a sense of movement that really shouldn’t be there.
The creature began to pump something into him- its body rocked obscenely against his face, that bulb at the base of its organ forcing itself against the flat of his tongue and the back of his teeth in turns.
The organ thickened further, spreading his mouth wider even, and he choked once more, air already scarce and suddenly not enough. It was filling him with something, waves of god-only-knew-what expanding and contracting the organ as it traveled downwards to his gut.
It fucked into his throat slowly but unceasingly, the rhythm never interrupted no matter how he struggled. No sound escaped him more than weak whimpers and whines over the need to preserve what little air he could access, and he could feel the organ rubbing back and forth against the raw inner walls of his throat.
The other one began the same movement, rocking into his ass- the knob against his prostate let up, but only for a moment before it was back, pressing again and again as the creature shoved into him endlessly. It felt like being struck by lightning over and over again, and his body jerked and twitched helplessly, whines and animal noises muffled into the mass of the creature sealed to his face.
Neither made any sign that it noticed or cared- he was being fucked within inches of his life, broken into and turned inside out and stimulated unceasingly, and still the creatures thrust almost mechanically.
The two moved in concert, fucking into him mercilessly at either end. He bucked under them, desperate for any escape from the constant sensation, and all it accomplished was the creature’s tail tightening around his cock. It wound closer, tugging roughly with every move the creature made against his body, a horrid mockery of the same action he’d used to relieve himself in the showers last night. A hysterical laugh bubbled in his chest, trapped there by the obstruction- was this really happening?
The creature’s tail jerked his cock in time with every thrust both made inside him, still maddeningly slow, and the combined sensation of it all, being spitroasted and jacked off, would’ve made his sight blur, if he still had use of it.
He could feel himself responding, skin much too hot and cock throbbing like a second heartbeat, and it was a horrible kind of anticipation, being so aroused like this, under these awful things. He reached for his cock, to- to grab the creature, to jerk himself off, he couldn’t tell anymore, not when he was so close, too close.
He’d barely made contact when the tail constricted mercilessly tight, and his world whited out. The orgasm burned through him like a wildfire, all his nerves feeling raw and scraped out inside, his whole body taut fit to snap, and still the creatures didn’t stop- it felt so good and it hurt so bad and god, he was dying beneath it all.
If anything, the creatures increased the intensity then, their organs stabbing into him with purpose, striking true each time. He sobbed, throat hitching helplessly again and again around the one in his mouth as its partner seemed to dig even deeper into his guts, his ass lifting off the ground with the force of every thrust and his hole abused and raw. The lightning sensation of that knot against his prostate was stronger, the creature pressing into him ever harder, and he was so weak, and he trembled unceasingly under it.
His fingernails dug into his own skin, having given up on reaching for the creatures at all- his hands shook, the grip weak even to his notice. He just wanted to feel something that wasn’t the violating touch of these things, the unforgiving thrusts, and the hard press of the ground beneath him.
Fuck, he could feel it through the skin- as his hands lay over his torso, he could feel the movement of the creature’s organs below the surface, the relentless shift and shove of them inside him, venturing and retreating as he was fucked. It was a horror he couldn’t find it in him to process, and he took his hands away as if burned, grasping desperately to the rocky ground to anchor himself.
There was no end to it, the creatures’ harsh movements rocking him back and forth between them, and he felt he must be losing his mind at the torture of it all.
It was pitifully easy to make him cum again, the thrusts once coinciding inside him, his torso spasming under the pressure and making him feel as if their organs could meet in the middle of his body, and tipping him over the edge once more at the very thought of it, shuddering helplessly.
From there, he was lost in it, could think of nothing more abstract than the visceral pleasure-pain of this, the creatures fucking so deep and so hard into him at both ends, his cock grasped and tugged mercilessly and never once at any moment, at any angle, receiving a drop of relief or mercy from the sheer sensation.
Time lost all meaning as he was used, jerked and fucked and feeling as if he were being pulled inside out under the weight of it all. He was forced to the peak of orgasm again and again, and never once did the creatures so much as slow their merciless assault.
He lay limp at this point, the energy drained from him by panic and overstimulation- he couldn’t move a muscle if he tried. The constant pressure against his prostate and multiple orgasms the creatures had dragged from his body left him helpless, unsure if his limbs even worked any longer.
His legs lay awkwardly on the ground, the creature between them carelessly pumping away at his ass. His arms had long fallen from their position holding onto the tail gripping his neck- it was useless anyway, as he had no strength left to counter it if it decided to tighten further. Any movement he made was involuntary, the creatures rocking his body underneath theirs, an occasional twitch or jerk as the one in his ass mercilessly prodded at his prostate once more.
His cock ached, throbbing pitifully in the tight grip- he’d long run dry, and he’d lost count of how many times he’d came already. He’d started to black out after the first three, each time unclear how long it had been before he regained what senses he had left.
He had not thought to assume things could get even worse, but dread still rose in him when he felt a third creature mount him- its spindly legs stabbed at his torso, its own organ dragging wetly along the goose-bumped skin of his pecs.
What could it possibly be planning- he had no more orifices for it to fill, unless it planned on stabbing him through and creating one.
It was only when the creature perched on his chest, seemingly resting, that he realized it was waiting its turn. Was waiting for one of the first two to be finished with him, waiting to take up its place. There would be no end for him in this hell, he realized. One creature would finish and the next would mount him- his abused throat and ass would have no reprieve, no chance for him to recover or regain his strength. No opening for escape.
This would be his life now, until he starved or died of exhaustion, or until one of these creatures got overly enthusiastic and cut off his air entirely.
He was being kept.
