Corporal Tia's body was slick with sweat, her t-shirt sopping and disheveled, stuck in wrinkled clumps to her upper torso; Her belly bared and shiny; Her strapping muscles quivering with a strong blend of fear and extreme sexual arousal as she held her body aloft on her elbows and her splayed feet, her trembling thighs wide apart. She curled her pelvis upward, rounding her back in a way that made her lower abdomen tighten as the Alien's large mouth descended between her open thighs and revealed its long sharp teeth as it gaped open, dripping with drool and menace. Her breath caught in her throat as she watched the Alien's large mouth slowly cover her sex and mound, engulfing it and squeezing down, it's sharp teeth sinking into the soft flesh of her lower belly and the tender dimples where her inner thighs met her crotch. She cried out as it gripped her to intimately and felt its small mouth extend, pressing hard against her vulva, mashing the plump lips there flat.

“oh my god!” Tia whimpered - a sound she rarely made - then gasped as she felt herself being penetrated - her vulva pushed out of the way, her labia stretching across the clenched teeth, the Alien's slick bone-hard small jaws tight as they forced their way through her tight opening. These 'small jaws' still bigger than her own fist.

The Alien seemed to know what she wanted - its movement was slow and deliberate, and though the hardness of its mouth and exoskeleton caused her pain, it attended to her body like a lover.

A dark murderous lover. I'm not getting out of this alive, she thought to herself.

...

Word had got around the base that had been created to contain the Aliens that a few of the female troops had flirted with the danger of exposing themselves to the Aliens as a sexual thrill. The story was that one of them had gone too far and an Alien had taken her sexually and killed her in the process. Rumours were whispered about the woman's demise, the sick erotic tale of a deadly coupling between Alien and a human female. Tia didn't believe the rumours at first, but when she did find that a female Private had been reported MIA at the same time the rumours began, she began to think it was possible. Then a friend slipped her a stick containing the closed transmission that the girl had made with her headset during her Alien encounter. As Tia listened to the fuzzy audio and watched the blurred dark images of the transmission recording she felt the tingling rush up and down her body as she realized it was real and that Private Flores had gone willingly to her death. She had felt her stomach flutter and threaten to expel her breakfast as she watched it, but at the same time she felt a hunger awaken in her loins.

Tia had been transfixed by the sight of Flores' open thighs shaking badly as the gleaming black alien descended between them. The jerking of the camera as the Alien took her only allowing brief glimpses of what it was doing to her was disturbing - it appeared to be using its mouths on her sex. But it was the audio - scratchy and muffled at times though it was - that cinched it for Tia. Flores' ragged breathing as she let the Alien work her body and the guttural exclamations as she responded. The static was bad, the voice distorted at times ...

“... [static] ... oh gawd ... it's [static] ...ing teeth ... biting me ...”

Then blurred movement, shadows, a glint of light on the black Alien skull, the passing image of one of Flores' inner thighs smeared with spatterings of blood. Then the camera facing the ceiling of the boiler room, rusted pipes dripping rusty water - Tia knowing that Flores had thrown her head back, relishing the sensations of the Alien taking her. The scene shifting in a rhythm - the same rhythm as Flores' sexual grunting as the Alien fucked her with its small mouth. Then briefly a blur and a quick shot of Flores' belly, distended a bit, something moving inside it, rolling up and down, making the transit from her mound to just under her belly button, and Alien hands gripping her hips, its sharp fingertips dimpling and penetrating the soft flesh of the sides of her belly drawing little rivulets of blood.

“...ungh! [static] oh fuck, oh fuck oh [static] fuuuuck meeee!” This last tortured moan followed by a scream as the camera jiggled and hit the floor, rolling and coming to a rest upside down on the filthy rusted plates. It must have fallen from its perch behind her ear.

“... oh gawd .. oh dear gawd ... the tail ... [static]” And on the left hand side of the screen, upside down is Flores' right foot and calf and rare glimpses of part of her bottom and thigh. The blackness of the Alien's form crouched between her legs, its hands gripping her hips, its long tail curling and moving there like a segmented boney snake sliding into her body. The muscles of Flores' bum and thighs working hard, shaking badly. From the speakers a deep guttural sound.

“... [static] .. too fucking deep ... ugh!” the tail and her body jerk. “Ugh!” Jerking again and again and again - a deep firm rhythm. The sound of gagging, choking, retching. The spattering sound of liquid. “... stop ... stop! ...” Then Flores' foot is lifted from the floor, her leg kicking wildly, the shadows showing that the other leg is doing likewise. The sound all static now, louder, like something is impacting her microphone. Then a spray of red - blood for sure, maybe some shredded flesh. Whatever it is, some hits the camera lens and blinds it. And out of the static a weakened but sexual voice, almost a whine;

“[static] ... oh dear gawd ... [prolonged static]” then a long quavering wet moan that is broken by a series of weak rhythmic grunts. This continues for some time until Flores falls silent and wet sounds continue for some time.

And the recording ended.

...

Tia squeezed her eyes shut and clenched her teeth as the Alien pushed its small mouth into her cunt, feeling the hard ridges as it forced its way into her, stretching her painfully. The “plunk” feeling echoing deep in her core as the thickest part - its jaws - passed the narrowest part of her passage and nested inside. Then her eyes opened wide as she felt it slide relentlessly deep into her body, so much like a machine - unstoppable, unmerciful - deeper - deeper. She felt her cervix pressed flat up against her uterus, her cunt filled and stretched. It pressed a little further, leaving her in awe of her own capacity. There was no give to this shaft within her - not like a cock that has some flexibility, not that she'd ever found a cock this large. It was like a thick and slippery hard-ribbed bone inside her and now the Alien started to slide it in and out - it felt like a dull impalement, over and over.

“oh shit” she heard her own voice echo in the hot and humid metal walled room as it fucked her with its small mouth. She could feel the thickness of it sliding up and down the tube of her cunt, massaging the tender walls, the ribbed shaft stimulating her g-spot, and the thickness of the jaws pulling at her pelvis on the outward end of each stroke.

“... hwaaaah! fffffuck ... I can't handle this ...” Tia gasped and heard the helplessness in her voice.

...

How many times had she watched and listened to that recording? Too many to count. Too many to keep her sanity. So many orgasms as she played, watching it loop over and over. It had come at the worst possible time for Tia - she was depressed, deeply depressed. After the fiasco during the Elco uprising when in her panic she had given away her platoon's position by firing too soon. The inquest established that she was responsible for the deaths of six of her fellow marines and dropped her from Sergeant to Private. Soon after she had been redeployed here to be part of the company of misfits who now guarded the Xenomorphs. She had managed to regain the rank of Corporal, but all transfer requests were swiftly denied, the replies from Command terse and offering little explanation. But the unwritten reasons where there between the lines; she would serve out her tour on this rock and then not be accepted to re-enlist.

...

Tia listened to her own grunting as the Alien worked her cunt - not just her cunt; her belly; so deep; so amazingly fucking deep - sliding from shallow to intrusively deep with each unrelenting stroke, her guttural sounds pushed out of her in time with the rhythmic thrust of this creature's boney small mouth inside her. Her thighs first trembled, then shook badly, then started to lose strength, and Tia felt herself losing her ability to keep her pelvis aligned with the Alien's mouth. She cried out as she felt herself slipping - its teeth pulling at her flesh as it kept her in the firm grip of its large mouth. Then she felt the Alien's boney hard hands wrap around her hips, its long fingers curling and pressing their sharp tips in the furrow of tender flesh inside the wings of her pelvis.

“... ohhhhhh ...” Tia moaned and relaxed her own muscles, letting the Alien hold her pelvis to its mouth as she lowered her shoulders to the gritty floor of the chamber, her chin now tucked against her chest. She lifted her legs, opening her thighs wide, laying the soles of her feet on either side of the Alien's smooth hard skull and reached up to cover its hands with her own. It was holding her, supporting her now as it worked her.

Tia looked into the Alien's unexpressive eyes and saw the bulge in her lower belly moving up and down, transiting from her mound to under her belly button as it worked her - in and out - in and out. The thrusting was growing firmer and faster.

“... eat me ...” she whimpered, hearing the double meaning in her words, feeling a growing kinship with this thing that haunted the nightmares of most who encountered it. She gave herself to it now, relishing the sweet feelings inside her, tingling with the controlled violence as she coupled with this Alien being.

Tia often considered suicide during her off hours in the lonely confines of her bunk, but though she would handle her sidearm and consider how it would feel to slide the barrel into her mouth and pull the trigger, she couldn't bring herself to do it. She couldn't bear the thought of that harsh impact in her mouth being the last thing she felt. This was different. This felt like surrender - like giving herself, her body to a dangerous lover. Tia had never allowed herself to surrender to another before - not man nor woman. But this felt right ... Tia felt tears well in her eyes as she felt herself let go of all thoughts of control. Her sexual pleasure and the timing and method of her impending death was in the hands of this creature.

Tia grunted and gagged as the Alien thrust its small mouth deep and hard into her once more, the shockwave rolling up through the pit of her stomach.

“... feels so good ... so good ...” she groaned.

...

The marines had killed the queen and destroyed all the eggs in the first sweep of the outpost on this planet leaving only the Xenomorphs themselves. The marine Command wanted to finish the job and eliminate the remaining Aliens, but the scientific community won the day so the marines became zoo keepers.

What they didn't know was that as they studied the habits of the Aliens, the Aliens were studying them and the Aliens were fast learners. A species that was designed to survive in any hostile environment and against any hostile life form and soon learned about human needs ... sexual needs were one category that the Aliens came to understand. Unknown to the marines, the scientists discovered that the Aliens had begun to exude strong human sexual pheromones.

...

When Tia first arrived in the area that Flores had died her violent and erotic death, she had stripped off her jacket, boots, pants, and panties. She was very aware of her heightened sexual arousal as she entered the filthy chamber. An Alien crouched in the corner, watching her and she had felt the fluttering of both fear and excitement in her core as she slowly approached it. She knew that this was a nurse Alien from the briefing sessions all marines got when deployed here. She'd learned that the long penis-like probe that the nurse Alien could expose from within its abdominal plates was an organ that dispensed a clear jelly-like nutrient in strong spurts similar to a male ejaculate, but with more volume and force.

Tia had hesitated in her approach as the Alien slowly rose and stood before her - her heart hammering in her chest. When it did not move or show any hostility, Tia resumed slowly walking across the floor, feeling the grit and rusty scale of the floor on her bare feet. Tia had at last stood within arms reach of the Alien and waited, unsure as to how Flores had initiated the coupling that killed her. The Alien had taken that initiative for her;

It reached out slowly with both its long hard arms and wrapped its boney hands around her head and neck and pressed her downward, forcing her to her knees in front of it. It was at this point that Tia had began to sweat and tremble, knowing she had just surrendered her control to this creature and that it was beginning a process that would end in her death. But she also felt a strong sexual feeling spreading through her loins and belly as the musky scent of the Alien filled her nostrils.

The floor was littered with sharp debris that scraped her knees painfully as she knelt before the nurse Alien. She barely had time to balance herself before the Alien's strong hands pulled her face forward and she watched its abdominal plates part to reveal the long thick probe that slipped out wetly and protruded straight in front of her. Reaching up, Tia had steadied herself by placing her hands flat on the smooth hard shell of its thighs and opened her mouth, sliding her tongue forward and taking the probe past her lips. The Alien pulled her slowly but relentlessly forward and Tia had shuddered as she felt the probe slide through her mouth and press down on the root of her tongue, forcing itself into her throat.

Tia had gagged and choked as the probe slid deep until her nose and chin were mashed tight to the Alien's hard abdomen, her throat plugged tight - its hard boney hands pulling her tight to its body. Then she felt the first pulse and the odd fluttering violence of the nutrient jetting directly down her gullet into her stomach. She felt its probe swell in her mouth and throat and a second pulse filled her stomach. Tia had began to work her throat then, trying to move herself off of it, pushing with the flats of her hands. The probe swelled again and again came the pulse, this time over-filling her stomach, her belly growing painfully tight before it convulsed and her cheeks plumped as she vomited around the probe, the nutrient filling her mouth and gushing from her nose.

...

Tia was panting now, over-heated and sweating hard as she neared her orgasm from the rhythmic pistoning of the Alien's small mouth inside her cunt. By its feel, this one would be a g-spot orgasm - one of those deep shuddering orgasms that made her belly feel like it was going to expand to the point of bursting. The Alien slowed then, as though it sensed her impending climax. Slowly it pulled back its small mouth until its clenched jaws were pulled tight against her opening, just under her g-spot. Tia gasped and began to shake, her body stressed as it lingered on the edge of orgasm. She felt the Alien open its small jaws, the bony ridges pressing hard against her g-spot. She could feel the sharpness of its gripping teeth inside her as it opened that jaw wide.

“... so soon ...?” Tia whimpered, feeling those teeth and knowing how tight they could grip and rend flesh.

As she stared into the Alien's expressionless face, Tia cried out softly as she felt the small jaws sliding slowly forward, deep into her once more, the teeth of the gripping jaws scraping along the roof and floor of her vagina. She felt those teeth contact the deepest flesh of her cunt, pressing hard, the plumpness of her cervix between them - she could feel it throbbing from the surrounding pressure. She felt each point of each tooth as it pressed hard inside her, then she cried out louder as she felt those jaws closing. She felt the impossible sensation of her cervix being gripped by those teeth, its meaty flesh clamped tight.

“... oh baby ...” Tia moaned, “... you got hold of me ...”

Then a new sensation; “... unghhh!” - as slowly the Alien began to retract its small jaws and pull her insides outward.

Tia opened her mouth wide and cried out gutturally as she felt it pulling down on her cervix, pulling her uterus with it, feeling the odd sensation of her inner organs moving. She watched in morbid fascination as her lower belly distended, rounding and firming as too much meat was pulled into too small of a space. The flesh under her belly button now looking hollow as it compressed her uterus toward her pelvic floor.

But along with the pressure came the strong sexual throb as more and more pressure built under her g-spot. Tia squeezed her eyes shut and began to pant like an animal, her hands slipping from the Alien's to cradle her swollen lower belly. The skin there was tight and the flesh under it firm - almost hard - as the Alien pulled her sexual organs tight against her opening. Tia felt like a passenger within her own body as her orgasm slowly rumbled to life beneath her trembling hands, she felt the convulsing, the twitching, as her hands shook and slid on the slippery sweat on her lower belly.

Tia clenched her teeth and hissed loudly as she orgasmed hard, her body convulsing, her thighs squeezing tight around the Alien's smooth skull, her toes curling and pointing inward. This was the most intense orgasm of her life, and as it burst wetly in her lower belly it spread through her body, energizing every nerve ending, Tia wished that she could communicate with the Alien and tell it to kill her in that moment as she would love to go out feeling that amazing sexual bliss.

As though understanding her telepathically, Tia felt a rigid hardness find her anus and press inward. Its tail! The Alien was penetrating her anally with its boney tail.

“ohhh ... you're doing it now ...” Tia whimpered, knowing the end was near.

Like a long tapered wedge, Tia felt the tip slide deeply and painfully, opening her anus wide, straightening her rectal valves and stretching her rectum out inside her. Tia could feel that her rectum was too short to take much more ... she could feel it stretching and pulling tight. And at the point where she felt she could truly not take any more, it pressed deeper and more firmly and she felt her bowels moving around the tip of the tail, encompassing it like a sheath as they shifted within her belly to accommodate this invasion.

“Hwwwaahhhh!” Tia grunted loudly, squirming in the Alien's vice-like grip, rolling her head from side to side. All at once the tail stopped its penetration and Tia opened her mouth to catch her breath, but it was not a reprieve; She felt the Alien tense it's body then the tail thrust hard and fast inside her - just moving an inch deeper then back again.

“GNAHH!” Tia grunted loudly at this shock to her abdomen. She felt the Alien tense again and again felt that sickening hard thrust inside her.

And again.

And again.

And soon it was fucking her with those short hard thrusts and the pain and feeling of such a deep invasion of her belly was overwhelming.

Tia sensed that the Alien was enjoying her torment and that thought seemed fitting to her. She felt the Alien was taking revenge against the human race for its destruction of its own cohort - revenge focused on her, as it had been focused on Flores. As it will be focused on others who will come here for this treatment. One by one, marines like her would come and offer themselves to the Alien to see release from their own tortured lives and become sacrifices to pay for the sins of humanity.

Tia soon became aware of a liquid bloat in her abdomen and knew that she was bleeding internally. She lay the flat of her hands on her belly and felt the swelling there - the tightening of muscle and skin. The fear that she would simply bleed out and slowly lose sensation and consciousness tickled the back of her mind.

“Do it” Tia tried to use her command voice, but her words came out in a weak whimpering whine., “Just do it”

As if understanding, the Alien's tail slithered out of her in one long smooth pull, leaving her gasping and feeling hollow as the tip flicked out of her gaping anus. Tia heard the tail clatter across the metal floor beneath them. Opening her eyes she looked up into the Alien's expressionless eyes as it adjusted it's grip on her hips, lifting them higher, pressing her shoulders hard against the floor. She felt the pressure in her head and neck as it held her there - it was as thought it was bracing her body for what was to come.

As Tia watched the Alien move its head so its jaws were poised just above her lower belly, she suddenly caught the dark blur of swift movement over the Alien's right shoulder. It had slipped its long tail behind it and raised it high like a scorpion. And its movement toward her was swift and the impact hard.

The sharp tip of its tail slammed hard into her belly, just inside the cradle of her pelvis on her left side.

“Glurk” Tia heard her wet guttural grunt as the tail slammed into her belly, driving deep, puncturing her gut and ovaries and womb in one brutal thrust. Then the sickening sucking sensation as it was pulled free and up into the darkness of the room, swiftly followed by the dark blur over the Alien's left shoulder. It struck her in the exact same place on the right side of her belly - driving deep once more, destroying her insides.

Tia grew silent then and her eyes stared at nothing as the Alien withdrew its tail and slammed it again and again deep into her lower tummy, bruising, rending, and puncturing over and over and over.

It was tenderizing her flesh.

Tia was lost in a world of penetration and pain, feeling her belly being punctured over and over - each thrust slamming hard into her body, jolting her, jerking her form still held tight in the Alien's grip.

As a final thrust, the Alien raised its tail high and thrust one last time into her stomach just below her sternum and the shock of that stopped Tia's struggling heart. And as she started to slip into a final endless sleep, Tia felt the Alien's mouth open and slam its small jaws into the shredded flesh of her belly, jerking her body upward into its open large jaws.

It began to feed.
