Haley was a scientist and believed in her trade. Theories, hypothesis, tests, trials, errors, more tests, experiments, discovery, wonder. Testing her ideas and figuring out new secrets about the universe based on skill alone was such an intoxicating idea. It was a drug. Haley wouldn’t admit it openly, but she got such a rush of energy when she finished even the most mundane of tasks. When she was younger, she used to think that there may have been something wrong with her dopamine reactors and that they fired randomly. Now, she theorized that her rampant drug use in her younger days had scrambled her sense of what was rewarding. That was something she could test.
After she finished this experiment first.
Lights flickered overhead, bulbs cracked. Somewhere in the distance, a door banged closed because of bad circuitry. Half of the room was shrouded in darkness. The computer screen in front of her blinked, random numbers appearing out of order, trailing from one side to the other like a stream. A stream of information. There was a large, glass wall in front of her meant for prisoners or traitors who were on the ship. It was a one-way window.
Haley stepped over a corpse split in half, entrails decorating the floor like black snakes. As a scientist, she wasn’t squeamish. Blood and body parts were science themselves, each person a little chest of discovery. Part of her wanted to inspect the dead soldiers and staff members that littered the room. Source of death. Caved skull. Impalement. Burns. Heart attack. Stray bullet to the neck. She noted these in her head as she walked over to the door that gave entrance to the glass room. The handle was smeared black with someone’s blood. Haley ignored it.
It felt good to be naked, in her base form. Clothes were only for convention, to keep others happy. They had very little practical use outside of social norms. Look at that soldier there, with his armored helmet and breastplate, chest caved in like he’d been struck by a powered work loader. What good was that clothing? Perhaps only for shrapnel. Naked was much better.
The door usually required a keycard, but due to the damage the ship had sustained, as well as many internal systems failing, Haley was able to open it without one. The glass room was relatively untouched, spared from the chaos outside of it, barring the ventilation shaft being destroyed. Its slats were warped and twisted, ripped away from the inside. Such a sight made her flush with heat. Haley caught herself in the mirror.
Bright blonde hair in a bun. That was standard. Couldn’t have hair getting in the way of an experiment. She kept herself trimmed, mostly for her own comfort and not for others. Her breasts were modest, a comfortable handful each. A long, brown birthmark stretched from her hip up her ribs. When she was younger, she used to be so self-conscious about it. It was just a discoloration of the skin. Nothing to be ashamed of. She glanced back over her shoulder at the vent, hand snaking between her legs. She let out a little moan, sticking her fingers in herself. In the mirror, she saw everything.
Her greatest experiment so far had gone wonderfully, not a single variable out of place. The ship, *the Sleipnir*, was dead, sitting in space like a whale on the beach. The research vessel was the perfect place for her to work, and an even better place for her to test her new hypothesis. *The Sleipnir* came with a private security force, just like most Weyland Yutani vessels. At first, Haley had been worried that the small contingent of twenty-five paramilitary soldiers would be a problem. When they were wiped out, she made sure to note that down in her journal before coming here. It was fascinating. Really, truly fascinating.
There were so many things about the universe she didn’t know. If Haley could have her way, she would cut it up and peer into its depths, learn everything she could. She would run a trillion experiments all at once. Haley stuck a second finger in at that thought, moaning loudly and grabbing a tit, pinching the nipple. Her pussy was slick, and she sat back on the single metal table in the room, watching herself in the mirror as she masturbated. She wasn’t trying to be quiet. After all, this was for *science*.
She was the control variable, the constant meant to ensure she had complete results. Haley was herself part of the experiment, after all. The soldiers, her colleagues and superiors, even *the Sleipnir* itself, were all independent variables, things that could be manipulated and controlled by either herself or the final variable.
A shadow moved in the darkness of the ventilation shaft. Haley froze, a moan in her throat and three fingers in her pussy. This was the dependent variable, what was affected by her changes to the independent variables.
The xenomorph crawled out of the ship, as if *the Sleipnir* gave birth to the gorgeous creature. It crawled quietly down the wall, claws finding perch where there were none. Those same claws were smeared red. Its long, phallic head turned side to side, and Haley wondered if it could truly see her. That magnificent, mesmerizing tail swam after it. The obsidian alien seemed like a piece of the galaxy, a point of space time made manifest, a beautiful black slab of killing potential.
Haley found herself masturbating again as it stood behind her. She watched it in the mirror. The thing was at least seven feet tall when its stood, its carapace looking suspiciously similar to humans, with its boney chest and thin arms. She wondered, as it took slow, predatory steps toward her, why it seemed like it was made of bones. Xenomorphs, despite their grace and allure, looked alarmingly skeletal.
She was moaning and grinding her hips into her hand as it loomed over her. Even without the mirror, she would have been able to feel its presence. Its tails swished in the air, bladed tip flicking red specks onto the floor. Wonder whose blood that was. Who was its most recent victim. Would it be her?
The Xenomorph opened its mouth, hissing loudly. A chill ran up Haley’s spine. She understood how these beasts were so feared, as if they were every human phobia made manifest. Fear was an evolutionary necessity, but phobias were wholly irrational. She wasn’t afraid of this Xenomorph. After all, she gave it everything.
She’d give it more.
Haley yelped as she was grabbed in its claws and tossed against the window. She banged her head on it, seeing stars for a moment. The Xenomorph moved quickly, leaping over the table and grabbing ahold of her head. It felt so right to be in its clutches. All it had to do was flex slightly, and it could crush her skull. Haley pushed her hips toward it.
“Go on. Fuck me.” She moaned. The Xenomorph twisted its head left, then right. It snapped its teeth, causing her to jump. The only thing Xenomorphs wanted to do besides kill was breed. That was their whole purpose. Haley knew their breeding cycle but made sure that *this* one was special.
A cock drooped out of a sheath in its crotch, looking first like a slimy black tube. As it became erect, the cock hardened. She watched it with wide eyes. It was similar to a human in the fact it *was* a cock, but the tip ended with a flared head, much like a horse. She couldn’t see any balls but wasn’t surprised considering Xenomorphs relied on eggs and larvae.
Haley was dripping when it bucked its hips against her.
She screamed in surprise and pain, the long, thick alien dick pushing past her cervix and into her womb. Her stomach bulged obscenely, and she ground her teeth together as if the pain in her jaw would distract her from the pain inside of her. It dragged itself out and a toothy moan escaped her. Haley never would have imagined offering herself up for breeding, but here she was, impaled on Xenomorph cock.
She loved it. As her new lover started to thrust, claws curled around her hips, Haley bucked back against it. It was hard to ignore the pain, but she powered through it. Whenever it thrust, its boney hips dug against her ass. It certainly wasn’t being gentle with her, slamming her against the glass window, but she wanted it like this. It was truer to their breed.
The Xenomorph stepped back and lifted her hips up off the ground. Haley scrambled to try and keep her grip on the glass, fingertips squeaking as she struggled. It let out a great screech as it started to move faster. Surprised by the sudden aggression, Haley could do nothing but stay there bent over, preparing to be a bred bitch for her new overlord.
“Hnh, hnh, hnh, f-fuck,” grunted Haley. She’d never been gutted like this before, treated like literal meat. Humans were so selfless, seeking the pleasure of their partner. Even the most selfish of human partners at least wanted her to cum so they could validate themselves. The Xenomorph didn’t care about that at all. It didn’t even see her as a human, something with a greater conscience and sense of self than it. To the Xenomorph, she must have just appeared as a warm incubator.
That thought made her cum, and she squealed with glee. An incubator! Yes! She had to know if this breeding method wouldn’t be as lethal as their usual reproductive cycle. If she survived, then it could change the whole species. It started now, in this room, with the whore scientist impaled on big black Xenomorph cock.
It continued to stretch her out, juices dripping onto the floor like a leaky faucet that wouldn’t turn off. Her hair had fallen out of its neat bun, golden locks hanging over her face. She watched her lover in the mirror, towering, ghastly frame pumping as quickly as it always had. What an amazing amount of stamina it had! She felt another orgasm boiling in her guts, each breath a hot puff of lust. She wasn’t losing her mind, but Haley was so enraptured by what was going on that she couldn’t help but forget about a few things. What would it be like if someone interrupted them, seeing her getting fucked like that?
She squealed like a pig when it pushed against her, forcing her to stand straight against the glass. Her tits mashed against it. The Xenomorph released her, placing its hands and legs on the window. Now, sitting vertically to the floor, its cock started to move again. It didn’t *need* to thrust, its cock slipping in and out of its sheath.
“F-fuck, fuck, fuck,” Haley gasped. She felt its cock deep inside of her womb, and because of how it stretched her it ground against the window as well. Spikes of pleasure rocked her body as she was pinned there by the superior species. Her legs shook, toes curling as another thunderous orgasm shot through her. Haley ground her teeth but couldn’t keep herself from crying out. “Fuck me! Fuck!”
The Xenomorph let out a hideous screech and she felt its cock hilt fully inside of her. It throbbed, and the cum came first. It must have been a lot thinner than a human, considering the wonderful green ichor came spilling out of her like sludge. She groaned in pleasure as something else came through its cock. It wasn’t an egg like she was predicting. Haley could only assume that she had just become the incubator of a pre-Xenomorph larvae. She felt it enter her womb and then curl up, the strange sensation causing her to shudder.
Her lover retreated, its cock slithering out of her. It crawled off the wall, towering over Haley as she slumped down and felt her stomach. If she pushed in the right spots she could feel the serpentine larvae inside of her. It was…It was…
Beautiful.
With tears in her eyes, she looked up at the galaxy’s perfect killing machine. Clicking its mandible and chittering, the Xenomorph tilted its head down to her, pressing its smooth head against her. Like a good father would.
“It’s going to be wonderful,” whispered Haley, which caused the alien to jerk back like a startled cat. She smiled up at it. She would become its incubator. She would be the chosen one to birth a whole new sub-species of Xenomorph. Once that was done, her experiment would be complete.
Haley extended her arms as the alien grabbed her, dragging her with it through the vent to its lair, where she would stay until everything was finished. She was so happy at the idea, dopamine receptors firing. No, Haley wasn’t crazy, just a little addled from her younger years.
Now, she was a scientist, and all the variables were in place.
