Amanda's ass had gotten her into trouble again, only this time for all the wrong reasons. The creature, she knew now, was snarling in discontent as with utter mercilessness its writhing member violated her. The tight hole it had burrowed itself deep inside was not the one it wanted. She realised this when the creature's long tail wrapped around her middle and pulled her up, propping the engineer on shaky knees.

With the weight of her body pressing her chest into the floor, Amanda was too weak to fight, to try and bolt away or cry out for help - if such suicidal thoughts had occurred to her at all. She did not even dare to look back as the full heft of an alien cock slapped down onto the crack of her butt, sinking down into the fleshy crevice. The thick, slimy length of it dragged downwards, accompanied by a long, drawn out hiss, and Amanda was trembling as it wriggled over her sore, stretched anus. A reflexive clench puckered her smarting hole, but it would be little more than a futile defence. Fear kept her still, kept her locked in place, because now, cruelly, she understood with brutal clarity the Alien's intent.

Her rape was no accident; it was not a freakish, anomalous display of behaviour. This monster had hunted her ceaselessly all over the Sevastopol, stalking her through the vents and shadows, and now she knew why.

Amanda took the Alien's penetration with a silent scream. It was not a swift thing, like a man hot with lust. That was something she had yearned for not a few minutes earlier, a stiff dick sliding into her cunt as a gorgeous, muscular body pressed her into the bunk mattress. This was not that. The creature's cockhead nudged like a curious snout against her before suddenly squirming to split apart slick, swollen lips. Amanda didn't have the room to feel shame, only mounting nausea as more than nine inches of dense penile flesh wormed its way into her.

She knew the measurement only because one specific toy in her collection could ever make her feel this full. Or half as full, because that thing certainly didn't have the girth of the meat stuffing itself inside her. Moisture sprayed over her lower lip as Amanda clenched her teeth, the scream locked behind them becoming a long, frothing whine. Size queen or no, the young woman had never taken something this big so deep and the position she was held up in only made things worse. Her walls were tight around the squirming intrusion, battered by its thrashing as it burrowed itself into her. And the Alien rattled sharply with each slimy inch, hissing like a punctured gas canister when Amanda's soft buns yielded to the pressure of its weight.

It was hilted inside her, so deep that the engineer felt sick. It made her skin crawl, the thought that entered her head as she bowed her brow to the cold floor and a throaty gasp escaped unlocked teeth. This was rape, forced on her by an alien, a ruthless killer - a monster. And yet, in the moment, all Amanda could of was that she had never in her life felt so full. That changed immediately in the next.

Two things occurred in harrowing succession. The Alien pounced on Amanda without warning, and now she screamed. Its harsh breath against her nape stirred her hair as large, long-fingered hands gripped onto her shoulders. The strength the creature belied was frightening, pulling the woman up off the ground in an instant. Suddenly she was upright, and the swift altering of position reminded her all the more poignantly just how thoroughly she was penetrated. For the moment, because then the next thing happened.

Amanda's eyes popped out of her skull when the Alien's squirming phallus abruptly stopped - and went completely rigid.

The creature's erection was sudden and forceful. Dense muscle stiffened and lengthened, another inch of cock almost physically growing inside Amanda and lifting her up off of her bare heels. Slime oozed into the merest gaps between her walls and the hard phallus, crammed so tightly now inside the engineer that the lubricating emission seeped out of her packed cunt to dribble in gloopy rivulets down the insides of creamy white thighs, Amanda, wholly impaled on the Alien's shaft, had no words to describe the sound that left her throat. Whatever it was, the Alien gave a long, searing hiss in response.

The sleek curve of its head hung over hers as its hands wrapped around her biceps, pinning the woman's arms to her sides. Spindly fingers criss-crossed her chest, pointed tips that could so easily puncture flesh pressing through Amanda's tank top vest into her breasts. Heavy strings of drool from its rattling jaws laced the air in front of her face, glistening underneath the common room's flickering lights. The Alien yanked her back so that her shoulders met the sleek bones of its exoskeletal chest, and even if she wanted to fight it she couldn't. Amanda realised too late that the creature's prehensile tail was slithering up the front of her body. Before she could even think to react, the thing was coiled around her neck.

Balanced precariously on the balls of her feet by the strong cock upon which she skewered, and pulled back against the monster with double the force, a prominent arch was bent into Amanda's spine that served to squash her plump cheeks up against its carapace. Her belly curved smoothly down towards the thatch of hair crowning stuffed, stretched lips as a result, which glistened with the product of her own humiliating arousal. Made taut thanks to her posture, the young woman's calves quickly started to burn, the ache spreading up the back of her knees to bloom across toned thighs where cords of muscles were tensely strung.

The blunt edge of a dozen bony ridges dug into the engineer's throat, squeezing in with enough pressure to make her panic. Amanda's breath was slowly being wrung out of her. Heedless of the danger, her brain selfishly engaging the most primitive instincts to save itself, hands flew up to grab the Alien's tail - but only reached the height of her chest, restricted by the cold grip on her arms. Pain blossoming hotly through her legs, Amanda dropped down onto the flat of her soles. Tried to, at least. It was a mistake either way. Eyes wide, she spluttered, choking when the constriction around her throat tightened. And then, as the woman lifted herself off her heels with a grunt, the Alien moved. Or rather, it started to fuck her. Except this felt nothing like sex.

The first, driving thrust the creature made felt like a punch.

Amanda rocked forward onto the balls of her feet, a harsh gasp spilling out of her mouth as an alien cock stabbed into her cunt. Pillowy buttocks absorbed the brunt of the shock of its body slamming against her, the force of the impact blooming up through the arch in her lower back. Her chest heaved forward, lungs tight as the wind was thumped out of her. And then she felt the Alien slowly withdrawing, free momentarily of the cold touch of its carapace.

Traitorous in instinctive intent her walls clenched, with a gross, wet sound trying to suck in the hefty, rigid length of alien penile flesh. But then even Amanda didn't know what she wanted when the monster surged back into her, filling her so completely with stiff cockmeat that her eyes rolled up towards the ceiling. The woman's mouth hung open in a state of stupor, the Alien's elongated hiss punctuated by choked wheezing. Globs of slimy, mingled juices splattered onto the floor as the creature partially dragged itself out of her, nether lips rolling outwards as inch after inch of thick, murky green muscle slid between them.

The engineer's senses were in utter disarray and her mind had melted into the puddle between her feet. Black spots were creeping up on the edges of her vision and Amanda barely heard her own strangled, monosyllabic voice as the Alien fucked into her.

"Oh - god - argh! - shit - fuck - fuck - ungh - hard - urrrgh!"

The creature's stroke was irregular, keeping Amanda on her literal toes. As though encouraged by the round buffer of her ass, the Alien battered its full weight against plush, white, rippling mounds, driving, seeking - fucking her. The lewd squelch of a greedy pussy followed the meaty clap of the creature slamming against her cheeks, and as it jammed its full length ruthlessly into the young woman, pushing deep even when its exoskeletal hips flattened soft, yielding flesh underneath them, Amanda could feel its huge, stiff shaft slide impossibly deeper.

With each thrust now she could feel the slight nudge of its crown against cervix, swiftly becoming a dull thump that tightened her core in discomfort. It was an added note of dissonance amongst all the other wild chords at play, and Amanda was too far gone to actively process it. There was a fiery ache in her chest, tears in her eyes as in futility she tried to reach her throat. The tips of her fingers brushed against the ridges of the Alien's tail, slipping off each time it rammed into her cunt and jolted her bodily.

The monster was snarling now, fiercely as it gripped her harder. Amanda yelped through gritted teeth as its long, pointed digits dug into her breasts, splitting apart the minuscule threads of her vest to press into tender flesh. It was thrusting harder too, if that was even possible, driving with such force that the woman felt like it was fucking her stomach. Such a notion was absurd, to Amanda, to any sensible thinking human being. But the Alien was just that; alien.

The woman's eyes abruptly grew round like plates . A choked, unintelligible protest escaped her lips as an eager hiss filled her ears like a burst of static. Amanda, for the first time since she had been pulled onto her feet, felt a horrible squirming sensation at the depths of her intimate core. It stabbed forwards without warning. She cried out as it struck her cervix, instinctively clenching down with every last muscle. It was the worst thing she could have done. The violent toss of her head and a desperate shout afterwards amounted to nothing. The Alien was a cruel, implacable monster.

Amanda screamed as it pierced the crown of its cock into her womb.

When the woman opened her eyes again, she found herself face down on the floor, limbs boneless and splayed out around her. She hurt between the legs, so sore that Amanda moaned tearfully with her first conscious breath. The common room light was steady again, she noticed then. That brought her little comfort, not when she could feel it seeping thickly out of her. It, was ejaculate.

The Alien had spent itself inside her. She remembered, with clarity that sickened her near to the point of vomiting right there and then, the sensation of what felt like a hose turned to full. It was nothing like a man's ejaculation, in weakening spurts releasing strings of gloopy white. The creature gushed, continuously, with hot cum that splashed against the walls of her womb. And something else amidst the spray of ejaculate, Amanda thought, though that was the moment the combination of blinding pain and asphyxiation stole her consciousness, like a lump that pelted up into her. But perhaps she was dreaming; perhaps this was all an extreme, sordid fantasy and in reality she lay upon a bunk in an abandoned living quarters, dead to the world.

Or perhaps not.

The rattle was soft and drawn out, fading slowly into silence. Her eyes and cheeks wet, Amanda looked up and turned her head to the left. There it was, crouched underneath the window looking out into the corridor. It parted its jaws as her gaze fell on it, a black, grotesque tongue flitting out and snapping at the air. Amanda started to shake, but not with fear; she didn't even have the strength to be afraid anymore. Tears slipped off her chin as the Alien canted forward onto its hands. Muscles throbbed in her jaw as it crawled towards her.

"Just kill me," Amanda whispered, with the monster's sharp, glistening teeth inches away from her face. It was over. She couldn't...she just couldn't. She just wanted this bastard, this monster to get it over with. It had tortured her long enough, hunting her like an animal with barely a moment's rest from its stalking shadow. And then, now, it had ruined her, invading Amanda so deeply she felt disgusted by her own existence. "So finish it," she told the fucker, lips trembling as it leaned forward with a quiet hiss. "Kill me!"

It moved, suddenly, and startled the woman jumped in her skin - but all the Alien had done was lift its great head, turning to the doorway of the room she had been occupying. Amanda followed suit, and this time fear took over her. Surely, the engineer thought, her eyes were playing tricks on her. Surely this could not be real. Nevertheless, her mouth hung open in silent terror as a second Alien, a perfect mirror to the first, dragged its tail behind it into the common room.

Amanda felt so small, so helpless and pathetic as both creatures hovered over her prone, leaking form. Even when smooth, long domes nudged between her thighs and sniffed at her aching sex, the woman moved not a single muscle. There were two of them. There was more than one. Always, there had been more than one. Amanda stared straight ahead, crying softly and waiting for the inevitable. But it never came, that swift, silent stab of the creatures' lethal tails into her back. Neither did either of them send little jaws smashing gruesomely through her face. Both, after investigating the abuse the first wrought on her, simply left.

She lay there for some time, even once they had gone. Encompassed by silence, Amanda trembled, in fear, and pain and confusion. Her mind could not unravel what was real and what was not, and so she remained as though the monsters were still there, hissing at each other over her warm, human body. One that had been brutally used and violated. Bile coursed up her throat and the young woman threw up, splattering vomit all over the floor. She retched hard and threw up again shortly afterwards, shaking weakly as her body wracked itself.

Or something wracked it.

Amanda felt it then, unmistakeably; something moving in her womb.
