having slow-rapid pregnancy thoughts

we have a fun, rowdy evening, and i fill you up multiple times. we didn’t use protection, but based on the time of month, it’s probably fine.

(spoilers: it’s not)

later that night, after we drift off to sleep, i have a bleary moment of semi-consciousness. i’m spooning you, hand on your tummy, and i can feel just the slightest unexpected resistance. at first i figure it’s just you breathing, but… i could swear there’s just an almost nonexistent stretch, so subtly rounding you out. i grin and pull you closer before drifting off again.

the next morning, you definitely look bloated, but not unnaturally so. you check it out in the mirror (i check you out in the mirror), we get breakfast, and you leave to go about your day.

you keep looking down at your bulging tummy throughout the morning, expecting it to go down, rather than do the opposite. by lunchtime, you start feeling fluttery movements, and you know something’s wrong.

it’s slow enough that no one can SEE you growing, but you very clearly look pregnant when you obviously weren’t the last time your classmates saw you. i’d guess you’re expanding at a rate of a month of gestation every three hours or so, and you’re definitely carrying more than one.

it certainly doesn’t help that your outfit is about as far from obscuring your figure as your wardrobe can get. when you sit down, you can hear seams stretching ominously.

- 🦑

I’ve been keeping track of my cycle for long enough now that i don’t think twice about letting you fill me up, even begging for it, pleading dumbly for you to breed me while im completely drunk on pleasure.

we both like when you keep your hand on my belly after sex, so of course you notice when i start swelling. im already asleep by then, and you don’t mention it in the morning - you just look at me in the mirror while i check the bloating, before we both move on with our days.

the bloating doesn’t go down. im a little self conscious of how tight my shirt is around it, and my jeans are fairly tight, like always, and if i weren’t in classes i would have them unbuttoned by now. I ignore it the best i can. my stomach isn’t upset or anything, if anything im more hungry than usual, so im having lunch when i start feeling flutters inside me.

i finish eating and rush to the bathroom, unbuttoning my jeans and pulling up my shirt — which feels even tighter than it was before — enough to see how obviously swollen I’ve gotten. i rub my hands over my belly a few times, making sure I’m not imagining it. im not.

i can’t do anything until im done with classes for the day. At least, I try to finish classes. i make it through my next one, but my third and final class of the day is interrupted by the seams of my jeans tearing - and not quietly, either. i go bright red and excuse myself, heading straight home after that.

by the time we’re both home, im five, maybe sixth months along, size-wise — though i look well past full term. im surprised my shirt lasted as long as it did, though the seams on that tear during my commute back home.

we have at least another nine hours left. and, past the concern, im indescribably turned on.

it’s not like i can get any more pregnant if we spend the next nine hours breeding, right?

pirates trying to navigate labor on their ship, old timey cowboys breeding each other on long journeys, regency era aristocrats pregnant with their secret lover's children, 50's greasers knocking up their straight laced partners (or vice versa), shit, even like, cheesy eighties alien movie style vibes with someone getting used as an incubator for an alien, or futuristic scifi shenanigans resulting in pregnancy

The Breeding Facility (Part 3)

reader insert | accelerated pregnancy | multiples | rapid hyper preg | alien pregnancy

a/n: this is most self indulgent and last part. definitely borrowed some of these ideas from other stuff i’ve read over the years

~~~

After your last three pregnancies were quadruplets, you were getting tired of the same thing happening. Your body’s growth still was incredible to you, but going home to your little bedroom all alone wasnt feeling like enough anymore.

As you talked with the other pregnant patients in the facility, you started hearing rumors about the men upstairs. At first you assumed they were talking about the owners of the facility, but you soon learned in one of the other wings of the center, there was an upstairs area dedicated to different breeding facilities.

Breeding facilities with men of another species.

The pregnancies were more extreme than anything here, and you were curious. You were greedy, selfish, wanting to know what was happening as well as get in on it.

At your last check up before labor with your current set of twins (a change of pace to make sure your body was still doing well), you asked your doctor about it.

“Oh, yes, there is a separate breeding facility for a different project. We are helping produce population for an alien species.” Dr. Ambrosia says, looking over your paperwork, “Honestly, hun, with your history, you would be a perfect candidate.”

After expressing your interest, she goes on, “Instead of being inseminated artificially, you will have sex with one of our volunteers. You get put up in an apartment home for the next few weeks and stay with him. Since the pregnancy is different from humans, there are some changes.”

Your doctor tells you about how these pregnancies last a little longer even while accelerated, and that the side effects are different. That’s why you stay with the father.

You sign some paper work and not even three days after you give birth, you are whisked away to the second floor.

Your new home is lovely, a studio with a small kitchen with a stocked pantry, a living and dining room, and a bed in the far corner.

You are only standing in the room for three minutes before a man enters. He is tall, broad, and his skin gives off a purple hue. He smiles at you before walking toward you.

His handsome features captivate you, making it easy when you realize he’s the one you’ll be having sex with. It’s not long before you are on all fours on the bed, completely naked as he plows into you.

His dick is quite large and when he comes, he releases more than you anticipated, leaving you bloated with cum.

You fall asleep soon after than, but wake to your hunger. Not only for food but also for him.

You break open the snack pantry, devouring three sleeves of cookies and crackers in less than five minutes. When you finally pause, you look down to see your stomach has swelled to look six months large already. Your belly isn’t as firm as it normally is, it’s a little softer, and you rub your hands over it excitedly.

“Do you feel it?” a voice calls behind you.

You turn around to see the man.

“Do you feel hungry for food and hungry for more seed?”

You find yourself nodding at him. He smiles and as he fucks you across the dining table he whispers in your ear the fact that he got you more pregnant.

Was it possible that this species could impregnate the same person more than once at a time? You came to the idea that you would be absolutely massive in just a few days.

And massive you were. Not even six more rounds of sex and you were barely able to walk. You were sprawled out on the couch presently, as your man fed you dinner.

When he wasn’t feeding you, he was fucking you. It was a lovely time. He took great care of you.

The best part was the companionship, the belly rubs, the food, the help getting up out of a chair.

With all the fucking you were doing, you had to keep eating. Every time he fucked you, a new baby was added. Along with the growth spurts from the already present babies, you were getting large quite fast.

Your belly was past your knees in just a few days. You couldn’t see your feet. Your arms had to rest on your belly with how wide you were. All you wore was a skimpy tank top that barely covered the swell of your breasts.

Your man constantly rubbed your belly. You found that when he mumbled something near your navel, your belly started to swell even more. You wondered when you would ever stop growing. You didn’t mind though.

A doctor came to visit on the fourth day, after countless fucks and more food than you had ever eaten in your past pregnancies combined. You were seated up right in the bed, where you hadn’t been able to move from since this morning.

Your doctor said you looked good though, and that once the very first baby implanted was ready for labor the rest would follow shortly after. She said it could still be a few days or even a week.

You moaned as you ran your hands over the swell of your belly. It was gargantuan. You couldn’t see the TV anymore. You could only see belly.

You moved your hands to your breasts which were more sensitive than ever. You were hornier than you had ever been.

As if senses your needs, you felt a pair of hands descend on your belly, rubbing in big circles. The man you had once described as a giant was now looking small in comparison to you.

“Are you hungry for more?” he asks.

“I just ate 10 minutes ago?” you ask back confused.

“no,” he says, “hungry for more of this.”

he mumbles against your skin and you feel a flutter of kicks, hearing a gurgle of motion as your belly expands even more.

You moan at the sensation, horny as ever by your expanding body, and he slides his cock into you.

When the expansion finally stops, he comes, dumbing another round of cum, another child into your already colossal dome of a belly.

“I can’t move,” you mumble later as he feeds you more food to feed your young.

“You don’t need to move, only grow.”

This is an insanely crazy mess you’ve gotten yourself into, but you can’t seem to mind.

~~~

It’s officially been a week, with no sign of stopping. The bed you are resting on must be made of extreme materials, because you now fill most of it, and your partner has to sleep on the couch.

Despite your massive size, he still fucks you, still mumbles his expansive words on you, still feeds you like there is no tomorrow.

With all the kicking and constant motion within your belly, you want them out. You miss going for walks outside. You miss when your tits werent taking up most of your vision.

You miss not being horny constantly. It was fine with the other pregnancies but with how large you’ve become you feel nothing but the need of release.

Your man is preparing food in the small kitchen, and you can barely see him around the large dome of your belly. You are seated half propped up in bed, which is the only comfortable way you’ve been able to lay these past few days.

You’re debating asking him to fuck you after he feeds you. Part of you wants it extremely badly. The other part of you isn’t sure how much bigger you can handle being. If you’re this horny at this size how much worse will it get before you finally go into labor?

As you see him finish up in the kitchen, you stroke the sides of your massively inflated midsection. You haven’t seen your belly button in days, let alone be able to touch it.

When you see him start to walk towards you, you feel it. Not labor, no, but another growth spurt. Oh god.

You aren’t sure how it’s possible for you to get any bigger, but you do, as you frantically rub your hands in circles around your belly. Whenever there’s a growth spurt, the babies inside of you get riled up, causing something along the lines between pain and pleasure.

Your man sees this, and sets down the plate next to you and plants his hands on your belly too. His eyes are filled with hunger but you aren’t even sure he will be able to reach your core to do anything about it. He’s filled you up so much. To the absolute max.

You’re immobile, completely owned by this man at this point. at his will.

You wondered how much longer you could last.

Happy No Nut In Me November!

What do you mean we aren’t even halfway through yet?

[backyardboytoy]

Having rapid preg thoughts -

Just existing when suddenly your gut/womb jumps out over your belt line. You're suddenly filled with squirming life of some kind. How many? You have no idea, but every minute, it feels like more movement. Your poor belly button audibly pops out with your next growth spurt.

Or the other kind of rapid preg where your body immediately knows you're pregnant upon creampie. you're getting fucked and they dump a heavy load directly into your womb. And you can feel when their sperm impregnates you because it's so warm and full. And your chest grows three sizes immediately spraying milk. Growing as quickly as possible because there's no way you aren't pregnant and your body knows it. And it needs to make sure it's ready to fed what's in you - what's already growing and swelling your womb to overstuffed capacity-

Okay, no more horni. I got it out... I'm normal again- I swear-

Waking up to a spontaneous pregnancy so big you can't get out of bed

"Hey boss? Yeah, sorry, can't come in today..."

"Yeah actually about that, you know how you guys offer maternity leave?..."

"y-yeah, yeah, I know I wasn't pregnant when I left last week..."

"Yeah... I can't really show up to prove it... Pictures? Sure yeah..."

"Oh no, they won't be of a positive pregnancy test, I'll just give you a POV of what I look like pinned to my bed right now..."

Storage Closet

Horny Plot Device University!

[this longer story is a bit of a prequel to Freshman Dorms II, another HPDU story. starring Quark (they/them) and Vic (they/them), two freshman goons at their dream college]

“This is the worst!”

“What!?”

“I said THIS IS THE WORST!”

The homecoming crowd was deafening.

“It was your idea to come here!”

“Well, I’ve changed my mind!”

A ball moved from one side of the field to the other, and the deafening crowd somehow became more deafening.

“___________!”

“____!?” Quark shouted back.

Vic gestured for Quark to follow. The two of them stumbled past a row of people and beelined for the exit. Finally, with a couple layers of concrete between them and the volume of the game, Vic spoke up.

“I thought that, you know, starting college, new year, new me, maybe the new Vic likes school spirit and football games.”

“And does New Vic magically like meaningless rituals and being bombarded by noise and lights?”

“No, New Vic does not.”

Quark snorted and bumped Vic with their hip.

“Am I the only one who’s impressed at how… flat, all the cheerleaders are?”

Vic cocked an eyebrow. “I bet they have some sort of agreement or contract or something saying that they can’t be pregnant during big games, or maybe the pregnant ones sit it out?”

“Or maybe they save it so after the game, if they win, they can give the team a celebratory bang, and if they lose, they can give them a pity fuck.”

“Is that how people think? Sounds kinda depressing to me.”

“Idk dude, just keep an eye out and see if they’re still flat after tonight.”

They smirked at each other, and walked quietly for a moment.

“So you don’t want to watch the game. What do you want to do?”

“Dunno. We could wander around, explore campus while everything but the stadium’s abandoned?”

“Cool.”

Vic gave Quark a side eye. “So… you were watching the cheerleaders?”

“I mean, yeah. They’re hot, and I can focus on the hotness instead of being worried that they’re going to go into labor or keel over from some Mystery Pregnancy-Related Ailment. Is that a thing? Do people do that?”

“No idea. I haven’t seen anyone on campus keel over from an MPRA, and if you were going to see it anywhere…”

“It’d be here. Yeah.”

“Would you want to try it out?”

“… What?”

“Pregnancy. The whole ‘magically pregnant’ thing.”

Quark stopped. “I mean… yeah, being here, you think about it…”

“You think about it, you see other people swelling up, you watch the cheerleaders and discuss their lack of big, bouncing bellies with, dare I say it, a note of disappointment?”

Quark squinted at Vic. “What are you playing at.”

“Just wondering. The cheap tuition isn’t the only reason the two of us are here, right?”

“Fuck off with the vagaries. Say what you wanna say.”

Vic stepped a little closer than Quark was expecting. “Quark, you’re cool. You’re badass. On top of that, you’re extremely hot.”

They grinned. “Tell me something I don’t know.”

“And I really like you. And if you want to try the whole… whatever is up with this school… I wouldn’t mind being the one you try it with.”

Their faces hovered closer together. Slowly, they leaned into a kiss, uncomfortably hesitant at first, then growing warmer and warmer to each other. Quark grabbed Vic’s hips and nudged up against them, feeling the growing stiffness between Vic’s thighs and realizing that they really, really wanted that inside of them.

They broke apart, breathing heavily and shuddering.

“You want to get me pregnant?”

Vic nodded. “You want me to get you pregnant?”

Quark nodded vigorously.

“Okay then. Let’s knock you up.”

“Wait, like, here and now? Do we wanna go back to the dorms?”

“We could, but…” They looked at each other. Neither of them wanted to wait that long.

“I saw a storage closet back there?”

“Gross. Cliché. Let’s do it.”

“After you, m’theydy.”

“Aaaaaaand just for that I’m gonna find someone else to knock me up, have fun jerking off in a closet!”

Laughing, Vic grabbed Quark as they started walking away and pulled them back. “Ok, I’m sorry, I’m sorry, I’ll never say that again.”

“Good, cos if you do, I will smother you with my pregnant belly.”

“Well, we’ve gotta give you that belly first, huh?”

They stumbled over each other, piling into the closet and closing the door behind them.

Quark’s voice in the darkness. “Great. Where’s the fucking light?”

There was the sound of Vic pulling a chain, and the incandescent light flickered on. Quark slowly looked up at Vic, inches away.

They attacked each other, almost tripping several times as clothes started piling up and getting tangled on the floor. Vic wore more layers than Quark, so there was a moment when Quark, stripped to just a black tank top and their socks (no homo), was grinding impatiently against Vic (who was still carefully undoing some clasps) chanting “Get me pregnant get me pregnant comeoncomeongetmepregnant—“

Finally, Vic grabbed hold of Quark, who climbed Vic like a tree, slamming their hips together and fucking like their lives depended on it.

“Come on, come in me, put your babies in me, make me huge and swollen like those cheerleaders are all gonna be!”

Vic slammed Quark against the back wall, pushing as deep into them as they could go, making Quark gasp, their eyes going wide. “I can’t wait to feel you grow, I can’t wait to feel you swelling up, your belly heavy with babies… oh god, I’m going to cum in you…”

“Do it, god I’d love that, I want to be so big I need a wheelchair to get around!”

“You think you can handle a belly that big?”

Quark grabbed Vic’s face and looked into their eyes. “Yes. I want that. I want that so fucking much, I feel so empty right now and I need you to fill me up.”

“Good, because I’m about to cum.”

“Oh fuck, oh F U C K”

They came together, shuddering and clutching, nails digging into skin, before collapsing to the floor, Quark on top of Vic, Vic still inside of Quark.

Vic felt something press against their abs. “Hey, sit up. I think…”

Bleary eyed and grinning, Quark sat up, and almost immediately started grinding on Vic again.

“Quark, wait—oh shit, that feels good—your belly—“

“Knock me up, I need you to fuck me full of babies,” Quark murmured, blissful and unthinking.

“Quark—oh, fuck—Quark, you’re getting big—“ As Quark rode them, Vic put one hand on their bouncing hips and one on their midriff, where their tanktop was quickly losing ground to the growing bump.

“Huh? Oh,” Quark finally noticed their changing body. “Oh fuck. Oh, holy fuck, you got me PREGNANT.” Mad with lust, they started bouncing furiously on Vic’s member.

“Oh, Quark—that’s the hottest thing I’ve ever seen—I put a baby in your belly,” Vic said, rubbing Quark’s swelling belly, the tanktop stretching thin.

“Do it again, do it AGAIN, fuck, my belly’s so big—“

“Fuck, you’re so good at this— I’m coming again—“

They both moaned as Quark felt Vic exploding, filling them with even more baby batter. Quark slid off, cradling their full-term belly, and felt it start to shift.

Vic was panting, exhausted. “That was amazing, holy shit, I don’t think I have any left in me…”

“Vic, I’m growing again.”

Quark saw something shift in Vic’s eyes when they looked at the expanding stomach now dominating Quark’s lower half. Their breathing deepened, and they sprang erect once again.

“Wait, are you ready to go already?”

“I think so, yeah.”

“I’m already so pregnant…”

“True. But, consider this: I could get you even more pregnant.”

“That’s a good point, I like that point.” Quark grinned and leaned back, spreading their legs wide.

Vic crawled over to them, and, leaning down close, the still-swelling pregnant mound pressing against their abs, they growled: “Let’s see how many babies we can fit in that belly.”

20 minutes later

The belly gently rolled back and forth, jostling its passengers, ensuring they stayed awake and active. Nearly a dozen babies squirmed inside, jockeying for wiggle room.

Quark was bent over, their gargantuan stomach stacked on top of a box of paper towels, while Vic worked on adding more to their ever-growing womb from behind.

“God, I’m still growing, I’m still growing from the last one and you’re putting more in me, I’m never going to stop growing…” Quark said, deliriously happy and horny.

“I love your belly so much,” Vic groaned, “I love feeling you swell up bigger and bigger knowing it’s because of how much I’ve fucked you, FUCK” They slammed into Quark, making every part of them jiggle and adding more babies to the growing process.

“Holy… shit…” Quark weakly patted the bulging orb that had been a cute six-pack less than an hour ago.

“Fuck… I think I’m finally done… Jesus, you’re huge…” Vic pulled back and wiped the sweat from their face.

Quark giggled, and, straining to lift their belly more than an inch above the ground, they turned to face Vic. Or, they tried to face Vic.

“Er… I don’t think I have room to turn around.”

“Hm. That’s okay, I’ll help you get dressed and open the door for you, and you can back out.”

“Insert obligatory truck backing up noises here.”

“Nice. Quality joke.”

Vic managed to roll Quark’s leggings up their shaking legs, giving their hips and ass a squeeze along the way.

“Okay. Beep beep time. Let me out.”

As Vic held the door open, Quark slowly waddled backwards, careful not to bash their womb against any shelves.

Then came the doorframe.

“Uhm. Hm. Vic?”

“Yeah, that’s… a problem.”

“Yeah, you got me so pregnant I can’t fit through the door.”

“Damn.”

“Yeah. Damn.” Quark looked over their shoulder at their accomplice. “You’ve made my belly so huge I can’t fit through doors. Vic?”

Vic, who seemed lost in thought staring at Quark’s backside, snapped out of it to look up and see Quark’s face, heavy-lidded, and flushed with arousal. They gently wiggled their rear, the lower curve of their crowded belly visible between their legs.

“You filled me up with so many big, heavy babies…”

“I shouldn’t have bothered putting your pants back on, should I.”

“Of course not, you idiot.”

Vic gently pushed Quark back into the closet and set to work bringing Quark up to a full baker’s dozen. Down the hall, an extremely tired-looking custodian radioed the admin building, letting them know of an impending situation.

[lemon-shortbread]

Sometimes I'm fine, and other times I crqve to be massively, exhaustingly pregnant with multiples and slowed down by the amount of baby weight I've put on, and how wide my waddling gait has gotten over the month. Struggling to do much of anything around my massive belly, tits, and ass as i wait for labor to finally start.

[plumpedxprincess]

so obsessed with growth spurts and rapid preg rn like imagine you're part of alien experiments and they don't really know what's gonna happen to you

you get inseminated and within an hour you look full term

but oh wait you're still growing, ripping the sides of your scrubs, your chest heaving as you grow

your hips, your tits, your ass, and oh god your belly

it's deformed from the violent movement, the rapid growth, and something is very much alive in there

you keep growing, past full term with twins, past full term with triplets, it's only been a few hours when will it stop?

you try to calm the creature down, rubbing your hands across the engorged skin of your belly, which is spilling off the sides of the exam table at this point

the doctors keep monitoring you but they don't know what's happening how much bigger you'll get and all you can do is lay there and accept your fate

[rbynight]

rapid preg is so underrated. honestly how could anybody not like waking up after a good fuck to find an unfamiliar weight stretching out your belly, hanging low in your pelvis, peeking out from under your shirt…

excuse me I need to go take care of something

[blubelly]

It’s so heavy… but master says I’m doing such a good job. I can’t get up from bed, and I can’t close my legs anymore, but master says they like me like this anyway…
