Alien Impregnations

Subject – Gastropoda Xenomorphica* (GX)**

GX, tentatively named "Belly-Burrower," is a newly identified extraterrestrial species exhibiting a unique reproductive strategy involving human hosts. Initial contact occurred on ██/██/████, near ██████████. The creature presents as a soft-bodied, slug-like organism, approximately 5cm in length, with dark-purple microscaled skin. Upon first contact, the creature employs a neurotoxin for immobilization, causing rapid muscle paralysis lasting approximately 24 hours. This is followed by the slug's penetration through the umbilicus of the host. Post-penetration, the GX undergoes rapid asexual reproduction within the host's abdominal cavity. Abdominal distension is a significant symptom, with hosts reporting extreme pressure and discomfort. However, this is relieved in a rather unexpected way.

My body’s been changing in ways I can’t explain. I’ve had painful growth spurts that leave me winded and sobbing, and now my belly is massive. I look overdue with twins or more... My skin’s stretched so far it feels like it’ll split. The veins over my stomach are so dark they look inked on, my stretch marks burn, and my belly button is pushed so far out it feels like it might pop. I’ve started to see bruises where they kick the hardest. Now they move constantly. Not just kicks, but full-body shifting—slow undulations, aggressive stretches. I swear to god they’re testing the limits of my skin, especially down low between my navel and pelvis. That’s where they push the hardest, like they know it’s the easiest spot to tear free... I don’t think they’re waiting for labor. I think they’re trying to force it.

Sometimes I’ll wake up mid-contraction, already pushing, shaking and drenched in sweat, convinced I’m going to burst open on the spot—and then it all stops. Or I’ll wake to that awful pressure building inside me again with my belly explaining excruciatingly slow. The noises are worse now too. Wet, sloshing, deep internal groans, like something shifting through fluid inside me. They’re louder... more frequent. My whole belly vibrates with them sometimes. It startles me out of sleep more than once a night.

Everythjng is getting worse. The growth spurts are happening more often, the movements are almost constant now, and the contractions have started and stopped so many times I’ve lost count. Every time, it feels like I’m seconds away from my water breaking—or rupturing. I’m scared I’ll either grow until I burst, go into labor and tear apart, or be trapped in something far longer, harder, and more painful than anything human bodies are built to survive.

I know I’m close. I can feel it. My body’s screaming it. But I don’t know what “birth” even means in this case. I’m terrified of what comes next. Has anyone ever experienced anything even close to this? Please... I need to know I’m not alone. Or what to do.

This is Dr. Aris Thorne, Senior Researcher at the EIHA. I believe I know what you may be experiencing. It is a newly posited theory in response to recent observations but so far appears to be consistent in our research.

As we've discussed on this blog before, some breeds are commonly described as "capacity bursters", where the pregnancy results in a bursting through sheer volume. This is in contrast of course to other "bursters" where the alien itself will claw its way out. From the symptoms you've described it sounds like we have a classic capacity burster breed. From the thick dark veins, burning sensation, and of course your massive size. And yet you've lasted a while without bursting, this is where this new theory comes in:

As the aliens adjust to your body's chemistry, they are not equipped to deal with other supplementary chemicals. We've seen instances of aliens reacting in unexpected ways to medications and drugs. This may be a shot in the dark but, I believe if you're currently taking testosterone that may be the cause of these interesting symptoms. The presence of the aliens within you is creating a feedback loop within your body, where the testosterone supplement you've been taking has been amplified. While the alien grows, your body in response is becoming tougher and stronger at a rate that exceeds the alien's ability to burst you. This in turn allows the alien to grow for longer than normal without bursting yet, causing an extremely overgorged belly and a pregnancy that seemingly won't end.

The reason you've felt like you're extremely close to bursting is because you've somehow outlasted a pregnancy that was meant to burst you days ago. When you feel like the aliens can't make their mind's up about whether to burst you, the reality is they haven't found a spot weak enough to burst yet.

Dr. Alice Sharpe here, with the limited info I have about your situation I believe I know what breed this is, and yes you may be in danger.

A phenomenon we dubbed the “Coterie Formation” was observed in Case Study 78B:

Abigail Chambers (24) - Caucasian, athletic build, previously exhibiting no hormonal irregularities. Initial contact occurred via anomalous pheromone detection in the suburban area of Oakhaven, California. Upon investigation, Chambers was found to be the focus of a rapidly growing group of women exhibiting late-stage pregnancy symptoms. Physical examination revealed a significant increase in breast size, disproportionate to abdominal growth. Analysis confirmed the presence of multiple, small (approx. 5cm) vermiform parasites nestled within the mammary ducts. These parasites appear to secrete a potent cocktail of pheromones – predominantly oxytocin, prolactin, and a yet-unidentified compound – that trigger intense attraction and maternal instinct in other women. Anya herself displays enhanced physical attractiveness, characterized by an exaggerated waist-to-hip ratio and unusually large breasts.

The parasitic lifecycle is unique. Chambers is believed to have been breast-feeding the other women in her harem. The larvae, ingested via this nipple-feeding, avoid the digestive tract by burrowing directly into the stomach lining. This results in a standard gastro-based alien gestation, with accelerated fetal growth compared to regular human pregnancies and heightened appetite in the host. We observed an average weight gain of 15kg in 3 weeks among Abigail’s followers. This rapid weight gain and increased appetite appear to be secondary effects of the parasite’s metabolic demands. These “follower” pregnancies produce fully formed, independent alien offspring, unlike the larval stage found in the original host. This suggests the initial host is essentially a vector for the species, maximizing its reproductive potential. The larvae are produced in a central host’s breasts to be individually implanted into susceptible followers. Observation suggests a hierarchical social structure within the “coterie”, with Chambers at the apex, exercising a form of pheromone-mediated dominance. Her followers acted as both birthing vessels and bodyguards. She would travel nowhere without her coterie and they were primed to act aggressively towards any perceived threat. This appears to be a way for this alien to ensure continuous pregnancies without the risks associated with other single-host continuous pregnancy arrangements. However, removing Abigail resulted in immediate collapse of the group; the pregnant followers appeared confused and disoriented, losing their previous intense loyalty and focus.

Report Author: Dr. Aris Thorne (PhD, Xenobiology)

We have observed a marked increase in pheromone-based congregational behaviour amongst pregnant human subjects carrying various species.

Agent Evelyn Reed (Field Operative, Level 4) - assisted Dr. Thorne in initial containment and observation of the phenomenon. These observations revealed a pattern: multiple women, each pregnant with varying extraterrestrial species exhibiting heightened hormonal states, congregating in remote, secluded locations, which we have designated as “hive chambers”. The hives themselves appear to be self-organising. The pregnant women present at these hives exhibit synchronized physiological changes – increased uterine contractions, intensified pheromone release, and a near-total suppression of individual agency. The effect is likely a combination of pheromonal manipulation and their own species' unique bio-chemical influence on their endocrine system, triggering a euphoric state that superseded rational thought.

Agent Reed’s observations and covert monitoring of these hives provided critical insight. The women within the hive were not simply congregating; they were actively engaging in sexual activity – a chaotic, yet seemingly coordinated, series of couplings between individuals carrying different species. This appeared to facilitate interspecies cross-breeding during pregnancy, a phenomenon only witnessed in select, rare cases before.

The Genesis of this occurrence appears to start with just two impregnated women. As their bodies, both overrun with alien hormones, get closer to each other, they exhibit a compulsive need for physical contact. Agent Reed's observations revealed a distinct pattern: "a synergistic amplification of the hormonal surges triggered by the proximity of their respective alien pregnancies. The effect appears intoxicating; an intense, euphoric pleasure radiating from them. Their hormones snowball off of each other, and eventually draw others to their shared state."

Once they've found a secluded spot (often the apartment of one of the hosts who lives alone) their sexual drive becomes unstoppable. This presents a striking visual - up to 8 hosts sharing a single bed, legs and arms entangled in a sensual dance of constant euphoria, aliens being birthed and immediately sliding into the already pregnant body of a nearby host to alter the DNA of her burgeoning young.

“The women’s movements were languid, deliberate, their bodies swaying in a hypnotic rhythm, a sensual dance of pregnant desire. The sight of their glistening skin, the gentle quivering of their distended bellies as they writhed in mutual pleasure, was both unsettling and intensely alluring. Their moans reverberate through the room, a symphony of ecstasy born from a shared biological imperative. The cross-species interaction within the Hive suggests potential unforeseen evolutionary leaps, with several women already showing signs of interspecies embryonic fusion."

“While we're seeing many traits we've seen before, some hosts becoming very fatty and decadent, others exhibiting increased muscle mass and enlarged buttocks, some species that have risen during these few days are unlike any others on file within the EIHA records. Some incredible and unique physiological traits have been observed in some of the women only a few days in. The host dubbed “Winter” has exhibited drastic complexion changes, where their skin glows with an iridescent sheen. It appears the hybrid pregnancy is causing her previously pale complexion to shimmer with a pearlescent luminescence.”

“By day 8 the hosts barely seem to open their eyes anymore, they navigate purely by touch. They explore each other's bodies with their hands and tongues, groping and licking constantly. The “paperclip phenomenon” I first noticed on day 4 has continued to escalate; where the more often a host gets double or triple impregnated, the more likely subsequently birthed aliens will choose that same mother for further impregnations. This creates an ever-escalating phenomenon where one host is singled out as the proverbial “bubbling cauldron” of these new alien species. The host dubbed “Megan” has undoubtedly become this cauldron. Her breasts are swollen and taut, she lays in the center of this entanglement of bodies with a belly engorged to a size that would prevent her from standing up even if she wanted to. The taut orb bustles with the constant motion of alien activity within. Whenever a new alien slithers inside her, the activity gets frantic and aggressive, but over time eases and the abdominal pulsing becomes rhythmic in nature. I believe this could be a visual indicator of the embryonic fusion of the various species."

"Her size and tightness seems to attract affection from the others within the hive - she is regularly the subject of belly rubs and kisses from the nearby women. Every time a new alien picks her as a host I worry this will be the one to split her open, but her body continues to adapt. Further study of Megan's physiology post-conclusion of this report would likely be extremely insightful.”

Reed’s report highlights the almost ritualistic nature of their actions, punctuated by rhythmic chanting and synchronized movements, suggesting some form of subconscious communication or shared psychic experience driven by the synergistic effects of the multiple alien bio-influences. This behaviour transcended mere sexual drive and suggested a complex, biologically-driven group consciousness.

The implications for containment strategies are considerable. The sheer scale of cross-species impregnation within these hives is unprecedented; the resulting offspring pose a huge biological enigma and possible threat. The mixing and amplifying of traits gives rise to new species that we have no current intel to combat in the wild at a rate that exceeds our ability to study them.

...the agent warned her. “Do NOT push” she repeated.

The pregnant woman writhed and contorted, clutching her bustling belly hard as she screamed loud. Just under the skin, violent movement was visible. She already knew this wasn’t a normal pregnancy, but she knew absolutely nothing about what was in store for her if she failed to heed the agent’s warnings.

“I know it will be extremely hard but do your best to relax your body” agent Wilson instructed. With the help of another agent she held the woman’s hands by her sides to prevent her from pushing on the belly. The inhabitant of her womb will not take kindly to being manhandled in any way, even if subtly by the tensing of her abdominal muscles. Pushing and touching must be discouraged. The screaming that the woman continued to engage in, however, is totally safe, and in fact encouraged. This alien breed is calmed by such shrill noises. This woman may make it out of this yet.

“Let go of me! Let me go!” She screamed, struggling against the agent’s grip. “Please ma’am, trust us, we are trying to save you.” the agents replied, though it was hard to hear over the screaming, “We’re doing what we can to prevent a bursting.”. Suddenly there was another large movement from the belly. A movement so big it seemed to lift the woman off of her bed for a moment. The woman screwed her face up in pain. When she opened her eyes, she was able to see her already huge belly start to swell and pulse even further. Tightening and tightening as it went. Her bellybutton was becoming stretched out until it was totally flat, the skin of her abdomen was so tight that the movement of the alien within her was explicitly visible. This was the moment where it would be decided whether the alien would birth itself calmly, or attempt to rip from it’s host, splattering her entrails across the walls.

The belly aggressively pulsed for a few seconds, threatening to explode, but the woman had followed the instructions perfectly, and it was starting to deflate again. After which point the birth would start. However, in a moment of last-minute panic, the woman dug her nails in the arms of the agents restraining her. Their grip weakened for only a moment, but that was all it took for the woman to wriggle her hands free and grab her swolllen belly again. All at once, she tensed her belly, pushed as hard as she could and dug her fingers into the tight skin of her belly.

ARCHIVE REPORT - Hysterical Pregnancy

The case of Ms. Elara Vance, a 37-year-old librarian and avid alien enthusiast, began with a seemingly innocuous bout of indigestion. However, what started as a mild discomfort quickly morphed into a bizarre and escalating saga.

Elara was a regular contactor of the EIHA, there are countless records on file of her emails, letters, and calls to the Agency. Most about potential alien sightings. Ms Vance is very well-read on various alien species we’ve had contact with, but appears overeager as none of her reports have led to anything substantial. They are very often chalked up to false alarms and informed anxiety.

Upon feeling significant discomfort in her abdomen, Elara, convinced her stomach cramps weren't indigestion, instead interpreted them as the burgeoning life form of an alien fetus, specifically a Xylar, a species known for its immense appetite in their gestation period as described in the many case files she has obtained. This belief was further fuelled by a profound and insatiable hunger, a hunger she attributed to the parasitic needs of her supposed extraterrestrial offspring. This wasn’t a normal hunger; it was a primal, almost violent need to consume. This hunger was likely a subconscious delusion brought on by her alien pregnancy anxieties that spiralled out of control.

Her initial gorging on pastries turned into a frantic consumption of entire pizzas, followed by family-sized tubs of ice cream and, finally, entire rotisserie chickens in single sittings. Her neighbour, Mr. Alan Henderson, witnessed some of these events, initially concerned about Elara's well-being, but then utterly baffled and morbidly entranced by her increasingly erratic behaviour and enormous appetite.

As the days bled into weeks, Elara's physical transformation was astounding. Her initial bloating progressed into a grotesque distension, her clothes straining at the seams, her mobility severely restricted. Far from being alarmed, she viewed her snowballing weight as concrete evidence of her alien pregnancy. She began crafting a nesting space in her living room, accumulating mountains of soft blankets and pillows, arranging them in what she called a “Xylar birthing chamber.” Mr. Henderson, who initially called to Elara’s home providing concerned observations, slowly transitioned into a curious co-conspirator, oddly fascinated by Elara's unshakeable conviction and intriguing physical transformation. He’d started delivering groceries to her home, even coming inside to stock her fridge so that she may continue to eat at extreme, elevated levels. The escalating strangeness of the situation caused details of the arrangement to spread through the community. Elara’s spiralling weight –as well as her insistence that she could feel the alien's tiny claws scratching from the inside- prompted a full-scale investigation by the EIHA.

Happy to be back!

MEMORANDUM TO: EIHA Internal Review Board

FROM: Dr. Aris Thorne, Senior Researcher, Sector 7

SUBJECT: Case Studies of Internal Security Breaches - Alien Pregnancy Fetishism

The following document details several instances of internal security breaches stemming from staff members engaging in risky behaviour for the purpose of alien impregnation.

Case 1 involved Agent Miller (Male, 37) – (Xerapodes species specialist).

Agent Miller was found in containment unit 4B, naked and attempting to initiate physical contact with a Xerapodes specimen. The Xerapodes is a sentient, bioluminescent tentacled creature known for its intensely pleasurable symbiotic pregnancy. There have been reports of people in the wild becoming addicted to Xerapodes pregnancies due to the intense physic connection the hosts feel with the inseminating alien. When Miller was caught, the Xerapodes had already implanted a nascent embryo within Agent Miller. Due to the inherent risks, the pregnancy was terminated, and Agent Miller was given a lifetime ban from EIHA facilities, as well as mandatory psychological evaluation. The Xerapodes specimen was unharmed.

Case 2 presented a significantly more complex scenario. Dr. Anya Sharma (Female, 42) – (Glargon morphologist) - orchestrated a sophisticated plot to steal cryogenically frozen Glargon embryos. Glargonians are known for their unique gestation process, in which the host experiences a temporary, but complete, psychic merging with the developing offspring. Those interviewed after this type of pregnancy gush about the unnerving but ultimately pleasurable feeling that is the sensation of being fully enveloped within the warm, wet embrace of their own belly. Dr. Sharma, it transpired, was hoping to achieve a prolonged psychic bond through self-administered illegal gestation. She was discovered after attempting to smuggle the embryos through a ventilation shaft. Luckily, she didn’t manage to incubate any embryos. The embryos were recovered, Dr. Sharma was arrested, her doctorate revoked, and she now serves a 15-year prison sentence. The incident highlighted major flaws in our security protocols.

The most recent incident, and perhaps the most severe, involved Dr. Jian Li (Male, 28) – (K'tharr geneticist). Dr. Li, using his intimate knowledge of K'tharr reproductive biology, had devised a way to keep himself continuously pregnant for many months, despite the usual gestation period for K’tharr embryos being only 3 days. He achieved this through a rigorous system of manually swapping out the growing embryos so that his body would experience a constant pregnancy. K’tharr pregnancies are not exceptionally pleasurable, but do provide a chemically-induced sense of ease and comfort during their short gestation. Dr. Li appeared to be attempting to harness a way to achieve a minor but steady and pleasurable high. His plan did not go undetected due to several physical and behavioural changes observed in Dr. Li by other staff at the EIHA. The first subtle clue staff noticed was his wearing of a larger lab coat than usual and buttoning it all the way up even in the hallways, in contrast to his noted usual style of leaving it open. Coworkers noticed he was more easily distracted, and was not as detail-focused and diligent as he’s known to be. People noticed his eyes unfocusing periodically, likely a result of the pleasurable dopamine hits his pregnancy was affording him. These details might not have flagged any alarm bells but unfortunately for Li, prolonged exposure to the hormone wash of this type of pregnancy started manifesting more significant, unignorable changes in him.

Li made much more frequent trips to the staff bathroom, sometimes up to 15-20 times per day, likely to masterbate on account of his increased libido. Every consecutive pregnancy builds on the libido increase of the last one, making his primal urges impossible to ignore the longer he tried to keep it secret. The buttons on his lab coat strained as he slowly put on weight. And most noticeably, he started developing significant mammary glands. Similar to the biochemical cocktail he was subjecting himself to that increased his libido pregnancy after pregnancy, his hormones were out of control, causing skin sensitivity, increased appetite, and development of female secondary sex characteristics. The breasts he grew were much more noticeable as they strained against his lab coat, but it wasn’t until they started auto-lactating enough to soak through the coat that someone sounded the alarm.

Dr. Li faces a significant sentence for this security breach. He is to be tried after a mandatory biological study period where our scientists can assess the impact these pregnancies have had on his body and whether any weaning-off of these hormones needs to be observed.

Please help me, I don’t want to pop 🙏

Subject: Case File Xylo-47B – Alien Pregnancy Progression Report

Subject Name: Anya Petrova (32) – Female, Caucasian, previously exhibiting no unusual physiological markers.

Alien Entity: Designation – Xenomorph-Gondolii (Preliminary).

Physical description: Initial scans indicate a bi-pedal, organism with a vaguely humanoid form. Size estimations based on uterine expansion and current growth trajectory are inconclusive without knowledge of full-term gestation length.

Petrova reports initial contact as a “blinding light” during a meteor shower. Her next memory is waking up face-down on the grass. On physical examination no external wounds were present, but subsequent analysis revealed microscopic puncture wounds consistent with ovipositor penetration. This suggests the possibility of the aliens being intergalactic scientists conducting pregnancy experiments of their own on humans.

She reports the initial stages of pregnancy as an intense, almost euphoric arousal, accompanied by strange, pulsating sensations within her abdomen. This progressed to extreme nausea, violent mood swings, and a rapid, alarming increase in abdominal circumference. Within 48 hours, her pregnancy was clearly visible. Initially the growth was uneven, her belly appearing lopsided towards the left side with very little abdominal fat gained with it. This smoothed out into a rounder, although bottom-heavy belly over the next few hours.

Petrova describes the internal sensations as a “constant, agonizing pressure” combined with moments of surprising intense pleasure. She appears unable to sit comfortably, her body constantly oscillating between discomfort and euphoria. Her hormonal profile is completely off the charts. She has displayed bursts of unexpected strength followed by a trance-like state where her body is flooded with a kind of hallucinogen.

Surgical removal is deemed increasingly risky given the entity's accelerated growth and the unpredictable nature of its bio-organic composition. Our current hypothesis suggests the entity will reach a critical mass within 72 hours, at which point we hope to be able to remove it safely.

He finally broke his wife out of her cell and was ready to escape the spaceship with her, but as soon as she stepped out, he froze. She looked a little different to before. First of all she was missing clothes; her pants had been torn off leaving only her panties behind, which were stretched to fit over her new...form.

When they were abducted she had quite a petite frame, but now only a few hours later, her thighs and ass had plumped up very significantly. And of course, the hardest thing to ignore, her swollen, engorged, impregnated belly. It had become so bloated and tight that her belly button had popped into an outie.

He cautiously took a step back, as if worried she could burst at any minute, "honey...what happened...?"

She stood there swaying for a moment, her eyes were unfocused and she was breathing heavily. Every now and then she would lurch a little as if about to throw up, but nothing would come out. Her hands moved drunkenly to her gut, squeezing it gently, causing some thick green slime to ooze from her inflated bellybutton...

Stifling the noises from her moans is a decent tactic to avoid attracting any more aliens to her location.

"What is happening to me?"

She could feel her body heating up. Something inside her felt...wrong...

Her whole body had the sensation of being about to sneeze, but never actually sneezing. She opened all the windows in her apartment and started fanning herself fervently to try to cool down, but nothing seemed to be working. She was sweating through her clothes. Soon they were completely soaked, and she was still getting hotter.

She began to strip her clothes off in a last ditch attempt to cool down. But once she did, she could see the mean, pulsing veins pushing up her belly. They were dark and thick, and soon they were throbbing. She reached out carefully and traced her finger along one of the veins. Her belly was slick with sweat, making it easy to slide her finger cautiously along. As she did so, she could feel the Vein getting fuller and tighter.

Suddenly she doubled over. It wasn't in pain, it was a natural body response. Her body was convulsing and constricting as though she was about to throw up, but she didn't feel sick. It was as if her body was responding to a sickness she wasn't aware of.

And then she felt it...

Was it...worms...? Something...squirming...

She looked down at her vein-striped belly and could only stare wide-eyed as it slowly started pulsing; the whole belly this time. It would swell a little and then go back down, but not all the way. It looked like she was breathing heavily, but with every breath the belly got bigger and tighter.

The movement was getting more noticeable now. You couldn't yet see it from the outside but she could definitely feel it, a sensation like she'd never felt before.

But she knew what it meant.
