My poor, round, overdue and overstretched belly dropped so low last night….. my water is on the brink of finally bursting out ….
She sat in church, smiling, listening to the pastor talk about the value of purity and the spiritual power of saving yourself for marriage. "I could never break that vow." She told herself, almost tearing up, overcome with love for God.
She didn't know about the "prank" her little brother had pulled when they all got together for the holiday. A syringe of sperm inserted between her legs while she was asleep after some pills were put in her drink. He'd just wanted to know what would happen,he'd just learned that it could cause something really special,but nobody told him what. He was careful, her hymen was still intact and everything.
Now her inbred abomination was swelling her belly round, though she told herself it was just being careless with her diet. No big deal. She had no idea she was growing a deeply sinful fruit inside her, one that no priest would ever excuse or forgive her for creating.
She would remain joyously oblivious until she laid in her bedroom in the middle of the night months later, the head of this horrific burden taking her virginity, making this profane birth even more obscene and sinful. Praying to God to take this misery and pain and fear from her, to show her mercy. But if he heard, he didn't care. And, push by push, her own cousin slid out of her. She only realized she'd been pregnant when the newborn began to cry...
New scenario ahead...
A sinister adoption agency that is kidnapping women who fit specific genetic profiles for their wealthy clients. They have their own secret hospital where the women are artifically inseminated, cared for to ensure successful pregnancies and where they give birth without any pain medication. Everything they do is recorded so the clients can watch the pregnancy progress and they are given copies of all ultrasounds.
Sometimes the women are kept sedated throughout the entire pregnancy only to be awakened when it is time for them to be induced and give birth. The women are never set free instead used as surrogates to create the so call 'perfect' offspring for clients.
Please, get inside! Call an expert! If you had your estimate, how much movement do you feel?
I keep trying to push it down but it won’t stop moving, what’s happening to me??
(A quick lil alien belly vid, I’ve gotten a few requests for more which has surprised me. Nice to know you missed me?)
Fun eldritch pregnancy idea I just had where whatever creatures are inside you are incredibly active, constantly making your heavy belly sway too and fro; frequent "kicks", too large and heavy and of the wrong shape to belong to any human infant, jut out and stretch your skin to its limits. When they're really disturbed several limbs will push out from multiple opposite directions; far too many than seems possible, even taking into account how large you've grown.
Yet, when you finally (finally) start giving birth, bearing down with all your might, you feel whatever's coming out of you is large and hard. It takes almost an hour of struggling until you finally push out what somehow appears to be an egg. Strangely colored, hard and heavy yet smooth to the touch, it could easily be mistaken for some sort of rock. Completely still and stagnant, you can't fathom how this is what you ended up giving birth to.
You don't have much time to inspect it further before another travels down and starts stretching you open, demanding all of your attention and effort; then another, each one feeling bigger than the last.
Yet your womb hasn't settled at all; it thrashes like never before, the kicks so frequent and tenting so hard that you worry what's in there is trying to burst out.
Still, nothing comes out of you but eggs, slow and steady, the increased activity in your womb doing nothing to help force them out; you have to do all the work yourself, bearing down hard, each egg obstinate about coming out of you. Your belly finally starts to deflate, though you can barely tell over the frenzied activity inside of you, though perhaps there are fewer kicks now? Given how long the labor's already been, there's no telling when the end will be in sight...
Pictures of a bith of twins. Her belly is extended to the max and so low.
My belly is bulging to the point if I take too deep of a breath, I swear I can feel more stretch marks ripping across my pulled skin 🥵
🤤🥵🥵🤧
A lot of people liked my rapid preg post the other day, so here’s something else in the same vein
I really love a pregnancy that starts off normal, maybe even until the 2nd or 3rd trimester, but then an external force brings the pregnancy to term in a matter of minutes. A pregnant woman going about her day, when suddenly her belly starts getting bigger and heavier…but that can’t be, right? Soon her water breaks, and she’s in labor…but she can’t be, she’s not due for another 6 weeks…?!
A pregnant person who is so hyper-fertile that thejr eggs can be fertilized at any place in their womb, resulting in a massive, bulbous belly, not spherical at all. It is lopsided and some fetuses are growing almost into the birth canal. This person can barely walk, their center of balance is off, but they are insatiably horny, and almost every fuck results in a new, bizarre implantation.
Y'all I'm being so fr rn but I need an alien to be occupying my womb like right now. Preferably something overly active and noisy that I can constantly feel and hear, but I'd even be fine with a heavy and hard egg. Ugh :(
There has been an outbreak of rapid pregnancy leading to unknown outcomes -- potentially dangerous! Please be aware!
Getting kinda big, I can’t keep my hands of my belly. What’s inside of it?
Wishing I was abducted and forced to carry a huge litter of alien babies that grow rapidly in my poor, massive belly, making me in constant discomfort as they squirm and fight for room.
I- ughhhh- I need to get these babies OUT before I explode 😩😩😩
How many months are you?
I’m already so big but have so much more growing to do! I can feel them all fighting for the little space they have 🥵
Spontaneous pregnancy may feel initially like a blessing!
But please, learn from these people who lost their lives to the outbreak of insemination.
In the near future, radioactive meteorites regularly fall to earth and cause non-cancerous tumors called teratomas to form in the abdomens of people exposed to them. While most people try to prevent these and get them removed, a subculture of online streamers purposefully develops and grows them as large as possible. Contains: object pregnancy, belly expansion, non-binary character, nbpreg, mpreg, fpreg, sci fi setting, bursting/popping, implied fatality. Content warning for dark themes and implied death.
[Previous Chapter]
When Nebula stepped outside they were surprised at how dark it was, as dark as the inside of their apartment. They hadn’t looked outside in so long that they had no idea whether it was day or not before they were actually out there. Their sensitive eyes squinted against the dull yellow light of the streetlamp, the electronic buzz humming in the air like a swarm of flies. If it hadn’t been absolutely necessary they wouldn’t have gone out at all.
The protective garments hugged against their abdomen like a vice, as tight as a corset. Most people hated wearing them, necessary as they were, and would invest a month’s rent or more into lightweight, less constrictive versions that (purportedly) offered the same level of radiation protection. Nebula didn’t mind the tight garment-- though they sometimes pejoratively referred to it as their ‘Mormon underwear’-- and in fact felt a vague comfort from the flattening quality of it. From the navel down, everyone was as flat as a Ken doll. An equalizer.
The inside of the convenience store was sparsely stocked and the floor had clearly suffered some recent water damage. A hideous tungsten bulb flickered overhead near the cashier. The entire back half of the store was completely unlit. Nebula rounded an aisle, grabbed a packet of instant noodles off the shelf, and brought them to the front desk.
While the cashier counted a dollar in miscellaneous coins, the television attached to the wall played the news with dull, barely audible sound, the accompanying subtitles scrolling across the bottom of the screen with a disorienting delay.
“Astronomers are predicting scattered meteors tonight and tomorrow. As always, the National Health Department is recommending remaining indoors until the showers have concluded and cleanup is complete. If you must leave your home, they are advising you to wear protective gear over the reproductive regions.”
The cashier, a male in his early 30s, slid a penny across the desk.
“This is yours,” he said.
As Nebula lifted their hand to retrieve it, they lifted their eyes and saw the definite outward curve of the cashier’s middle beneath his tank top. His belly pressed against the waistband of his pants, a thin slice of skin visible below his top. Naked skin, unprotected by the thick fabric of the radiation suit.
The man scratched at his belly, soothing the itch of a developing stretch mark, then tugged his tank down over the curve.
Nebula pocketed the change and the noodles and left.
In the mirror of their apartment, Nebula lifted their shirt and rolled down the long undergarment until it was folded up around their waist. Their fingers traced over the flat space beneath their navel, the sparse trail of hair that lead into their underwear brushing against the digits.
The masses that grew in the abdomens of people exposed to cosmic radiation weren’t pregnancies but looked like them. They most closely resembled teratomas-- masses of irregular but non-cancerous flesh that bundled up into heavy boulders inside them, displacing the organs around them and distending their bellies, stretching and rounding them out until they appeared as though they were with child. If the person had a uterus, the growth took root inside it; and if they didn’t, it usually lodged itself somewhere along the intestinal tract. Most people had the growths surgically removed as soon as they were discovered, if they could afford it. Sometimes saving enough money for the procedure took so long that the teratoma gestated inside them and grew into an intrusive bump on their middle. If they got large enough the host might not be able to bend at the waist or even walk. Fortunately, the procedure to remove it was relatively simple, if you could get it.
Nebula looked at their belly in the reflection and pushed it out, the smallest curve appearing, before releasing their breath and returning to flatness. The image of Angelique’s enormous womb flashed inside their mind. It must have been so tight. The skin must have burned from how large she had become.
They pushed their belly out again, pressing their fingers into it. Their prick was a hard, tingling nub of pleasure between their pussy lips, as big as the tip of a finger and buzzing with sensation as it rubbed against their underwear. Exhale; flat again.
Some people did not get the teratomas removed. They kept them inside and nourished them and let them grow. Some people exposed themselves to the radiation that fell from the sky in glittering fragments of shattered space rocks just so they could get a belly. Nebula watched them on their computer screen, watched them caressing their heavy mounds and gush about how much they loved being big and full and stretched to the limit.
Their eyelids fluttered shut as they rubbed themselves inside their pants, hand slipping beneath the compression of their suit, stroking their cock, rubbing their pussy juice over it, their other hand climbing into their shirt so they could tease the pointed nipple on their small bud of breast.
A belly so huge they could hardly carry it. So full their hips creaked, so massive their skin split and scarred. The heaviness, the weight, the shape.
Nebula imagined themselves as big as Angelique, bigger even, and came.
The meteorite was the size of a beach ball and roped off with overlapping stripes of yellow tape that bore the words CRIME SCENE-- DO NOT ENTER. The rock was hot, so hot that that Nebula could feel it from ten yards away, gray ribbons of steam licking the night sky as they rose from the object’s cracked surface.
The inside of the rock pulsed a neon green, lit from within. It illuminated Nebula’s face from below, their features bathed in the blinding, unnatural light. As they lifted the yellow tape, ducking under it, the heat became intense, almost too much for them to bear. A gust of air seemed to rise up from inside the meteorite, their hair wafting back away from their face. They were suddenly very aware of their unprotected abdomen, naked under their clothes without the compressive gear. The breeze kicked up, the space rock humming, Nebula’s shirt rising a few inches over their torso and exposing their belly to the radioactive debris.
This is it, they thought to themselves.
It wasn’t exactly clear how long they were supposed to stand in front of the meteorite before the radiation would have an effect. Their internet searches had been inclusive; nobody had ever done an official study on just how much exposure caused the reproductive growths to form, and the levels of radiation seemed to vary immensely from object to object. It was a total guessing game.
The skin of Nebula’s face felt tight and dry. Their eyes squinted against the light. The interior of the meteorite pulsed, throbbing like an organ, the intensity of the glow increasing until they were forced to look away with their arm coming up over their eyes.
They took a few steps backwards, nearly stumbling, the backs of their thighs knocking back into the crime scene tape and almost tripping them onto their ass. Taking that as a sign, Nebula dipped under it and headed back towards their apartment. The entire front of their body warm and dehydrated, like they had been sitting in the sun a little too long. They licked at their lips, feeling the cracked surface with their tongue.
The air became markedly cooler as they left the radiated area and returned to the main streets. A chill overcame them, making them shiver. A film of sweat coated Nebula’s hairline, the back of their neck. They had expected to feel like they’d done something naughty afterwards, like they’d shoplifted or told a lie, but they didn’t. Maybe it was because there was no way to know if it had worked yet. Only time would tell.
They hopped on their computer as soon as they returned to their apartment. In the bottom right of their screen, the chat box flickered with a pending notification.
Fr00tbask3they check out your guys stream he’s finally started coming along
Nebula opened up the streaming site and scrolled through to find Imminent Dad’s page. Fortunately, he was still online. When Nebula entered the stream they could see what their friend meant: the man’s middle was visibly more distended than it had been a few days ago. His belly was now so large that it encroached upon his lap, half the length of his thighs concealed by the growth pressing the flesh of his abdomen out into the open space.
The man caressed it, breathing heavily through the circle shape of his mouth. Nebula got the impression that this wasn’t merely an act. The mass had grown so large in such a short span of time that his skin was visibly flushed even in the poor resolution of his built-in webcam. His stretch marks had deepened, and widened, the scars ridged and purple as if he’d been clawed by an animal across his hips and gut.
“It’s getting...really big…” the model groaned, his palm cupping the underside to take some of the weight off his back. “And I’m starting to feel...ohh...some irregular contractions…”
The man’s middle seized, the flesh of his gut clenching around the teratoma inside him, his muscles pulling the growth in towards the center of his body. He cried out, both hands flying to the far end of his belly. A sickening noise emitted from his intestines, a low and wet churning that signaled his gestation was coming to an end.
He exclaimed, “Ah, fuck, it’s breaking out of me!”
The chat erupted in protest, pleading with the model to hold in the growth.
Breathe thru it!
dont u dare let it out
fuckkkk it’s totally gonna burst him he didn’t even get that big
The man’s eyes bugged and he attempted to pant through the contraction, his lips distended and sputtering, his thighs parting instinctively.
His massive belly dropped down on his lap dramatically, his entire middle blushing a furious red. The stretch marks, thin and scratch-like across his abdomen, began to widened and darken.
Wonder how he’s gonna have that thing
such bullshit his stream only just started getting good
On the model’s lap, red fluid began to weep from the stretch marks. The man screamed as his body began to expel the mass, unable to contain the size and weight of it any longer.
“FUCK, IT’S COMING OUT OF ME!” he bellowed, one of his hands flying to his navel, the other to the underside, his skin opening up beneath his hands. “IT’S COMING, IT’S COMING!”
Nebula exited the stream. Their mouth felt glued shut. They felt a vague sense of horror envelope them like a wet blanket. It must have been terrible to go through all that only to get that big. The model didn’t even get that large before his body started pushing the teratoma out. It seemed like such a waste.
Nebula wiped the sweat from their brow with the back of their hand. The consolation, they thought, was that Imminent Dad’s growth really wasn’t that big, so it would probably be safe to expel it manually. They might need to get stitched up at a doctor after, but it wasn’t so large that it would kill them. People had done it before.
Someone like Angelique, on the other hand, could not possibly survive expelling a teratoma that large. At its widest point, the growth was much larger than her pelvis, it just had to be. If she was unable to ease her contractions and her body continued to push it…
Nebula removed their glasses so they could rub their tired eyes with the heel of their hand. They pushed the thought out of their mind. Imminent Dad would be fine. People had birthed teratomas much larger than that and been fine.
He probably didn’t even look into preservation techniques, they thought. Absentmindedly, Nebula rubbed their palm against their middle.

There is a mass outbreak of very, very dangerous beings, for all genders!
Please, take a moment to check if your womb is empty.
Do you feel any hardness? A swell? Any movement?
The mass outbreak of spontaneous or unexpected swelling sensations continues! If you or someone you love seems to be suffering from unexpected:
* Belly growth, especially if it feels hard to the touch
* Small movements beanth the navel (or, more extreme, pressing movements)
* Increased sex drive
* Memories of being invaded
* Intense pain in stomach (CONTACY IMMEDIATELY)
Please note that any and all reports from the general public are welcome and will be processed by assigned agents. Possible responses from researchers regarding symptoms and possible plans of action may also be given on a case by case basis. We at the ACC are dedicated to assisting the public in any regards to alien impregnation.
What's the biggest a host has been without bursting?
This can vary from host to host, as well as based on the species. However, a few examples can give us a general idea of just how big some people can go.
Whether it be rapidly or slowly, some women reach sizes that are technically considered normal. However, the myriad of stretch marks tells a very different story as their body struggles to handle all the expansion. Given that this is still within the realm of normalcy, these are the most well documented.
Further still we reach the outliers, who all are well past normal sizes and are very frequently discovered sooner. Though there are very few occasions where ACC agents make it in time before birthing happens, the few exception have led to a well of data to go through.
Past this point are very few fringe cases that were almost always discovered after the fact. While all investigations are ongoing, we hope to find more information on these potential 'brood queens' as agents have taken to calling them around the compounds. Due to no better naming convention having been presented, the R&D department has taken to using that name until a better one has been presented...

Memes are fun and all, but the Storm Area 51 meme has unfortunately landed some people in some serious trouble/danger.
Although most people know it's a joke, this past Tuesday saw a few people attempt to break into area 51 as well as the EIHA facility. Here's the outcome of that:
Denise Kelly, 28, made it in without initially alerting the guards. She decided to venture in to our delicate brood-sac room. A room that no one is ever meant to enter. This room contains a wealth of eggs from various alien species. The presence of a fertile female in the room will immediately wake them all up, and that's exactly what happened. Although Denise was only impregnated with non-lethal breeds, the problem was that she was impregnated by 57 breeds at once. As you can imagine, that posed a bit of a spacing dilemma with them.
As soon as Denise had entered the room, our alarm sounded, but by the time we got there she was already in the state you can see in the picture. She was wearing profusely, moaning loudly, and thick blue veins had erupted all over her belly. Through her pained breaths she attempted to call for help, but it was far too late for her, a second later she split open, gushing a tonne of alien embryos all over the floor.
Next there was Susan Wells, who managed to get herself impregnated with multiple experimental breeds. This caused her belly to swell with a huge amount of alien amniotic fluid. Luckily we managed to get to her in time, and have been draining her belly as fast as we can. Susan, however, is in a near vegetive state, as the amount of alien chemicals attempting to influence her mind and body are overwhelming her physiology. Despite our instant care of her, it's unlikely she'll make it.
Rachel Bowman managed to escape the compound again after getting impregnated. She later proudly posted her enlarged body on social media, boasting of her alien motherhood. Even though the breed she got impregnated with isn't the most dangerous, it still poses a threat to society if she births it in the wild. A team has been sent out to track her down from these posts.
Ellie Holden was another escapee who managed to get herself impregnated with our newly formed, very rare, Armistus embryo. Armistus is a very hard alien to find or synthesise and releasing one has set our research back months. Armistus enjoys a strong, testosterone-fuelled host, so what will likely happen in the coming weeks is, Ellie will work out excessively and become extremely strong and muscled. It is important our team finds her before she becomes too difficult to contain.
Some people escaped without realising they'd gotten impregnated. Some aliens have an offset reaction and don't trigger until days later. This happened to Kenya Minto, a college student who travelled in to participate in the raid. She thought it would be a funny thing to do for clout, but the day after she left she began to feel these strange sensations in her lower belly. Like Rachel, Kenya documented this on social media, although she was clearly a lot more worried than Rachel was. Kenya had begun to hear from her friends that they were experiencing strange sensations and swelling. As soon as Kenya's belly started swelling, she snapped an anxious pic and posted to Snapchat.
All these surviving girls are being tracked down. You can send an ask to the page if you'd like to know the updates on them.
To say Lydia was struggling was an understatement. Going from single and partying to overstuffed and overburdened in the course of a few days took a lot out of a girl. Though it was hard to pin down exactly what cause her sudden and incredibly active pregnancy, her only clue was her date. She took a chance on a guy who seemed to have a fascination with sci fi and aliens. He claimed to have found and befriend one. Of course Lydia thought he was just messing around but he took it very seriously. She excused herself to use the bathroom, considering just leaving him and trying to salvage the night elsewhere. Yet his peculiar nature didn't make him a bad date. He was engaging and actively listening in conversation, he took enough care in his appearance that he was at least kind of cute and he make it clear he'd pay for whatever she asked.
After she returned to the table, the night was a blur and she woke up in her bed with a sweet aftertaste lingering in her mouth. From that point on it began. The stomach pains, the swelling of her belly as well as her breasts and the insane cravings that seemed to possess her any time her stomach growled. She practically ate enough for five guys in a single day.
Currently bedridden with her brood, Lydia didn't have any explanation for her condition. Her only saving grace, if she could even call it that, was the ACC was fast acting. She remembered her date mentioning it that night, calling them hacks and selfish. He apparently took issue with them capturing and containing alien offspring.
---------------------------------
Agents Lawrence and Jennings took the official report, both surprised by what they saw. Hearing of radical individuals was new for both of them, though their supervisor was familiar with the circumstances. Young women being impregnated, sometimes covertly, by fanatics seeking to 'assist' alien population growth. Thankfully, there were no complications and Lydia gave birth several days later. The specimen was contained and is under observation. Meanwhile Lydia's date is under investigation and local law enforcement are alerted to his activities.
I was practicing my breathing and my pushing…I have a feeling I’m going to suffer a long, hard, excruciating labor.
A woman goes to the doctor because she missed a single period.
She has a slight rounding below her navel.
She is convinced she is pregnant.
The doctors dismiss her. It would be too soon to tell. Still, she takes a test - positive. She's pregnant.
She demands a sonogram. Inside her are at least 30 small, round, dark splotches - implated embryos.
The doctors beg her to abort or at least cull the pregnancy. There is no way anyone can take this pregnancy to term. She refuses, and leavss the clinic, resting her hand on the small curve of her stomach. Nothing bad could happen from what she was eager and deaigned to do, right?
belly practise 5/5 — what’s in there?
Been inspired lately to be so pregnant and heavy that i am but a slow, sweating, panting beast
One of my favorite things is early stage hyper-pregnancy.
Someone looks 4 months actually just tested positive. Someone looks 6 months is actually stuffed full of zygotes. Someone looks 9 months is actually having a litter. Overdue but actually on x-ray it's someone stuffed with normal 5 month fetuses.
"Don't cum." I told him, desperate to finish. I felt so stupid for letting him talk me into not using a condom. This was so dangerous, but I needed to peak before we stopped so badly. "I'm trying... It's hard to fight it..." He grunted, and I could feel through the way his dick was twitching and throbbing inside me he was telling the truth.
"I mean it, don't cum!" I panted, wrapping my legs around him. I was so close, just a bit more... "Gah, it hurts!" He grunted, his whole body trembling as he fought his body's most base, primal instinct.
"Don't you fucking dare cum inside me! I can't have your stupid baby right now!" I said, throwing my head back, my plea trailing off into an utterly satisfied cry of release. It felt so good, I barely even heard him go "Ngh! F-fuck, no! I can't! It's coming out! Babe it's coming out of me right now!!!"
Spurt. Spurt. I felt it slamming into my deepest point, and that only made it feel better. I was so scared, but it made me cum even harder, knowing he'd failed, feeling him dig his fingers into my hips and pull himself in me as hard as he could.
It would be fine, I tried to tell myself, laying there, his seed oozing out of my most vulnerable place. It would be just fine, I wouldn't have to have a baby from this. I couldn't handle being pregnant right now, I hoped my body wouldn't let it take...
)----------
"Don't push." I told her, watching her in the passenger's seat, still wearing her sweatpants and shirt. Her belly was so huge with our little accident, and I still felt so guilty for what I did. But she was amazing like this, so beautiful, so powerful, even if this baby had made her miserable. "I'm trying... It's... S-so hard to fight it... Have to actively... R-resist the urge..." She grunted, clutching her thighs, trying to hold her legs together even though she clearly needed release.
"I mean it, don't push!" I managed, struggling to keep my voice steady. I could see how close she was, how much her body was straining. "Ungh... It HURTS!" She moaned, her thighs parting involuntarily. Her whole body trembled as she fought her most base, primal instinct.
"You have to fight it! If you give in even a little, this baby will come right here in the car! You said you didn't want that!" I secretly hoped for it, had delayed us leaving maybe a bit more than was reasonable, until she was complaining about intense, overwhelming pressure in her hips, said she could almost feel how thin and open she was inside. Was saying she almost felt like she needed to use the bathroom. Then and only then did I find the last thing we needed and headed to the car. She threw her head back, a desperate cry of pain and release escaping her as she bellowed "NGH! F-fuck, NO! I CAN'T! It's coming out! BABE, YOUR STUPID BABY, IT'S COMING OUT OF ME RIGHT NOW!!!"
There was a spurt of fluid, and the crotch of her pants became absolutely soaked. She screamed with effort, and I watched her pants bulge... More... Until with a beautiful sound of fluids pouring from her, the entire baby slid into her pants and panties, one big, desperate push after fighting with everything she had for so long sending our accident launching into the world.
"It'll be fine..." I told her, rubbing her leg as she looked down at the muffled crying coming from her ruined sweats. "I know you had to drop out, and we're struggling a bit. But we'll figure this out. You'll recover, it won't be a big deal. I promise." She just shook her head, let out a water "can't believe you did this to me... Fuck..." As she tried to force herself to pick up our newborn oopsie...
An astronaut, maybe part of a team of researchers working at the very edges of the space humans have explored, gets kidnapped by aliens. He's taken to some lab, experimented on, sometimes awake, sometimes unconscious, certainly never knowing what's being done to him.
Finally, though, he manages to escape, stealing an alien ship and plotting a course back to space dominated by humans. Space is large and distances are long, so even if nothing unexpected happens to slow the journey down, it'll be around nine months before he's there, give or take. He doesn't mind, though, so long as he gets back there he doesn't care how long it takes
But.. a while into the journey, he notices his belly begin to swell. Before long it's undeniable: somehow he's pregnant. With what, or how many, he doesn't know.
How does he manage the pregnancy, all alone in a stolen alien ship in the middle of wide empty space? Does it even progress the way a normal human pregnancy would, or does whatever's growing within him cause some weird (maybe horribly painful or otherwise difficult to deal with) side effects? Does he get back to other humans before he gives birth, or only after (or do others find his ship as he is in labor)?
He's terrified of what's growing inside him, not knowing what it is or how long or big its going to grow since he was unconscious for most of the experiments. He has no idea how he was implanted, so he's not even sure there's a way for whatever it is to come out. The aliens must have somehow put a synthetic womb inside him, but he doesn't know if it connects to anything, and he has no way of finding out on his tiny escape pod.
Months and months go by, and his belly swells like a balloon, quickly rounding out and bigger and tighter with each passing day. His skin is stretched taut by the halfway mark, and he's not sure how much more his tummy can take, hoping and praying it doesn't grow much bigger or he's scared he might burst. There's not much else on the ship, so all he can do to pass the time is rub his belly and feel his stretched womb undulate beneath his skin as it warps around the creatures. He's so big he can't find any comfortable position to sit or lay in, his heavy belly always pinning him down or squishing his organs in some way.
Somehow, his body manages to keep stretching as his belly continues to grow, almost in range of rescue after many painful months. He has no idea how the creatures haven't burst out and killed him by now, his belly is so huge, it looks like a grown man could fit inside his giant orb of flesh. The aliens must have done something to his body to allow it to stretch this far, because he's sure any other human body would have long since split apart under the pressure.
It's so huge he can't move anymore, not that there was much room to begin with, trapped beneath his writhing gut. It hurts so much now that he can't stop moaning and rubbing his swollen belly in pain, constantly feeling the unrelenting movements of the now massive creatures inside. They roll and kick within him, sending ripples through his tummy and making him scream and sob in agony. He begs them to stop, pleading for them to calm while he writhes beneath the monstrous swell, helpless against the unbearable pain. In pure desperation, he tries to push them out, screaming and clutching his tummy as he bares down with all his strength, but it only makes them thrash in anger. He tries and tries, delirious with pain, but nothing he does gets them to budge.
Finally, 9 months later when the pod reaches a human ship, they find him inside, sobbing weakly and begging to get them out of him. He wails and claws at his belly as they transport him to the med bay, barely able to breath under the weight. His belly his too big for him to fit into any healing pods, so he's forced to lay on a table, wheezing for breath as he's hooked up to life support. The doctors quickly set up an ultrasound to see what's inside him, smearing cold gel all over his bruised skin and pressing the wand into his flesh.
They see his womb isn't attached to anything, meaning the creatures had no way of coming out on their own, no matter how hard he tried to push. They also see that the creatures have actually become fully grown inside him. If he hadn't escaped, the aliens that implanted them would have most likely removed them in time, but without them, they had kept growing to maturity inside his womb, leaving him with a belly full of adult sized aliens inside him.
The doctors look concerned with their findings, and step out of the room to discuss, leaving him alone in the cold white room.
