Chapter 0 - It Came From Outer Space

Ava awoke in a room - more a hallway, really, with the long, thin dimensions - made entirely of metal. Silver-gray material, polished to a shine, formed a space without corners or edges; instead the walls curved gently into the floor, creating an ellipsoid interior. Soft, diffuse light without a discernible source lit the chamber, playing across dozens of chrome capsules, attached to the walls. It took her a moment to realize that she, too, was in one of these capsules, but with the front missing, the only thing allowing her to see the rest of this chamber. She was held in a full nelson position by the interior of the pod, mostly encased in silvery material, leaving only her head, torso, and full, round ass exposed.


After taking a moment to wake up, Ava wracked her brains to try and recall what happened - the last thing she could remember was driving down a mostly empty highway before a vivid green flash of light filled her vision. A moment of weightlessness, and then nothing. Then she found herself here, naked, and - 
Her reverie was interrupted by a hiss as the mechanical door at the end of the hallway slid open with surprising speed, and a figure stepped through. Its skin was a deep green, and it had a distinctly feminie shape, with breasts even bigger than Ava’s - no small feat, with her F cups - and hips to match. However, as Ava slid her eyes down the newcomer’s form, she noticed a distinctly un-feminie feature around the groin - a fully hard cock, perhaps a foot and a half long, and thick as a can of soda. A pair of full, heavy balls, nearly the size of softballs, hung just below it, obscuring her pussy from view. Despite herself, Ava felt her pussy moisten significantly as she imagined getting properly railed by such a monster.


She wouldn’t have to imagine for long, it seemed, as the figure strolled down the corridor of pods and finally came to a stop directly in front of Ava, turning to look at her, the tip of her dick pressing gently against Ava’s stomach as she casually inspected the latest arrival.


“Are you… an alien?” asked Ava, not entirely expecting an answer.


“Ah, good to see the translation chip is operating properly. Yes, I am.” The futa replied, “I’m with the galactic space rangers. You see, we’re a bit short on staff-” she continued, fondling Ava’s tits. “-and we need to produce more healthy recruits quickly.” She let her hand drop. “Nice and firm, good. You’ll make an excellent breeding bitch.”


“What?!” Ava cried, even as her pussy clenched at the term. It had always been a secret fantasy of hers to get used over and over to produce babies, getting fucked endlessly as she pumped out children.


“Oh, quiet. You wouldn’t have been picked up by the scanner if it didn’t turn you on real hard to get used like this. Now, seeing as I’m feeling a little backed up” - at this point the alien squeezed one of her balls, causing her cock to twitch and slap against Ava’s stomach - “I think it’s about time to break you in properly.”


With that, she brought her hand down to Ava’s pussy and began working it over, sliding a finger, then two, inside, and letting her thumb lightly tease the clit. As she added more fingers, both of them could hear the squish of Ava’s juices leaking between the invading digits, her cunt clearly broadcasting that it was ready and aching for a good, hard dicking. The alien gave a smirk and pulled her fingers out quickly, causing Ava to involuntarily jerk her hips and release a soft groan of desire.


“You’re real wet, huh bitch?” Said the alien. “The system chose well. I’ve never seen a breeder this wet on her first day before. Go on, have a taste.” With that, she held her fingers out towards Ava’s mouth, just close enough for her to lick if she craned her neck. Part of Ava thought that straining herself to lick up her own pussy juice was degrading, but a much larger part - the part that had occasionally driven her to jill off many times a night to the idea of getting bred over and over by thick, heavy cocks - made her desperately stretch her head forward against her bindings to slobber greedily all over her breeder’s fingers.


“Good bitch.” The alien said, and the genuine satisfaction in her voice made Ava’s heart flutter. Then Ava felt her breeder’s hips draw back and the futa’s fat cockhead nestle against her folds and her heart fluttered for a much different reason.


“How do you want it, bitch?” The alien asked, calm and steady, not a hint of taunting in her voice, though she already knew the answer.


“Fuuuuuhck I need it, give it to me deeeeep…” Ava drawled, arousal boiling in her stomach, making her mind buzz. Her fingers twitched, aching to squeeze that cock, her tits, her breeder’s tits, anything to relieve some of the tension thrumming through her body.


The alien just grinned and increased the pressure against Ava’s cunt, the lips slowly spreading until the force was too much to bear and nearly her whole length barged its way in, veins battering Ava’s clit thanks to the carefully-chosen angle of her thrust.


“OooooOOOH!” Ava squealed, experiencing the deep, all-consuming pressure of her breeders hot cock, twitching around the improbable size and grinding her clit, harder than it has ever been, against the groin of her newfound cock goddess. And then her deity of dick began to thrust, and she totally lost it.


“Fuck! Yes! Fucking breed me hard! Give me your hot futa babies and make me huge! I want to have your kids forever!” She babbled, grinding back against her breeder’s thrusts to get her that much deeper inside her, feeling the cockhead tickle her deepest nerves just millimeters from her cervix. Her walls stretched around the power and thickness of her breeder’s hot futa dick, a delightful tightness that was only enhanced by the ridge of the alien’s cockhead grinding against her g-spot hard with every thrust.


Every swing of her breeder’s hips packed Ava with more cock than all the other dicks she had taken before combined, and she clamped down each time, begging with her body as well as her words for her glorious breeder to give up that delicious futa seed and make her complete, give her a litter of alien babies that would grow up to be as sexy and potent as their “father”. Ava writhed against her bindings and slammed her hips forward, panting with unconstrained lust at the heat and the fullness and the unrelenting, powerful strokes.


Ava lost track of how many times she splattered her breeder’s groin with squirt before she felt the futa’s balls tense up and cock slam home to give Ava what she had been begging for. Ava’s eyes rolled in dazzled pleasure as she felt the futa’s urethra bulge at least a half-inch outwards with the volume of seed traveling up through it. The agonizing feeling of the enormous cumblast working its way up the futa’s cock only made Ava’s subsequent orgasm even stronger.


Ava felt her cunt and womb fill slowly with her breeder’s unrelenting release, finally finishing up only after she had a bulge in her stomach that made her look a few months pregnant. As she lolled in mindless bliss, the futa pulled her softening dick from Ava’s cunt and inserted a dildo of the same chrome metal as the pod, locking her tightly closed and forcing her eggs to stew in that ocean of potent alien seed.


“Mmmm, you’re one of the best bitches I’ve had this whole trip, shame I won’t be breeding you that often after this. Still, I can always visit from time to time even if you’re already knocked up. You’d like that, wouldn’t you bitch?”


Ava merely moaned with ragged desire as the capsule closed on her, leaving her with just the wonderful afterglow and the feeling of gallons of hot spunk in her womb.

The Next Day


Ava awoke to a stomach bulging much larger than the day before and a note written in some kind of smudge-proof ink just above her navel. It was a bit difficult to make out, given that it was upside down and backwards from her perspective, but the translation chip she had apparently been implanted with during her abduction helped out. It read:


Please be courteous and remember to knock up your broodmother before leaving! 


She wasn’t certain what it was referring to, but was soon distracted when the alien from before returned for a bit of more recreational pussy-pounding. Hours later, exhausted and blissed out on afterglow, she noticed her belly had gotten ever bigger, more so than she would have expected just from the alien’s gallons of potent seed.

Three Days Later


The last few days, Ava had absolutely ballooned in size, to the point that she was looking ready to pop any minute. This increased the logistical difficulties of getting pounded by her breeder, but the occasional visits had still been highly enjoyable.


It turned out the lid of the pod was see-through from the inside, and she was able to watch (and grind hard against the chrome dildo in her cunt) as multiple different alien futas came down to breed, or just enjoy, other bitches. Occasionally she would hear the sounds of moaning start up without having seen anyone come through the main doors, but between the hormones of being massively pregnant with futa aliens and the number of personal kinks this hit for her, she was a bit too horny to think about that too much.


She would get her answer, however, when her contractions started.


It turned out whatever alien science or biology allowed her to take her breeder’s foot and a half of cock also allowed for very easy births, as she got a delightful feeling of fullness that was almost like her heated fuck sessions, save that the whole thing was going the other way. As she contracted and moaned at the baby coming out, she felt the chrome plug slide out of her cunt and the whole pod reshape itself like a liquid, forming a place for the newborn to rest as it emerged. Finally, with a squirt of love juices as Ava came, the new futa alien was born.


Ava’s initial motherly musings were cut short as the new baby began to grow at an incredible rate, gaining inches in seconds. The pod opened and gently lowered the alien to the floor, giving her plenty of room to grow. Within a few minutes, she was the same size as her father, albeit with more youthful features and smaller breasts. The one thing which was not smaller, however, was her cock, which Ava could see, as it rose to full erection, was pushing two feet long.


The new alien stretched, as if waking up from a good nap.


“Ahhhhhhh, it’s good to be alive!” She said, testing out newborn muscles and limbs. In the midst of rolling her neck, she caught sight of the message on Ava’s stomach, and an impish grin spread across her face.


“Mmmm, well, it’d be bad form to start out my first day in the universe by being rude, wouldn’t it? Let’s get to work.”


This was immediately followed by a gush of juices from Ava as she realized that the alien’s cock was now positioned right at the entrance to her pussy, ready to send her spiraling into bliss just as it’s “father’s” had. And then, a moment later, her newborn daughter’s cock was buried to the hilt in her drenched cunt, her body was alight with sensation, and the sight of her beautiful offspring was flickering in and out as her eyelids fluttered rapidly. Ava’s new daughter had a much different style to breeding than her predecessor, preferring long, unrelenting strokes rather than passion and speed. It was agonizing after the intense, animalistic extacy of the last few days, but, after a few moments luxuriating in the continual heat of arousal, Ava was convinced.
“Ohhhh yes, give me everything. Bury it deeeep.” Ava mumbled, grinding against her daughter’s groin and panting with the sensation that sparked in response. “I need more hot alien jizz, more daughters to breed me. Give me it all!”


This put a glint in the eye of Ava’s new daughter, and those long strokes slowly ramped up in pressure and speed, bringing the simmering heat of Ava’s lust to a turbulent boil. She thrashed and moaned in her bindings, her arousal at her own daughter’s efforts to knock her up leaving her fired up even after her second orgasm. At last, Ava’s cunt twitching erratically, the alien made one last stroke that left her completely hilted before she leaned back slightly in relief and absolutely flooded her mother’s womb with seed. Ava’s stomach bulged slightly with the volume, and from experience she knew it was nowhere near her limit.


“Mmmm, that was good, but we better go a few more times just to make sure, hm?” her daughter commented, and Ava merely moaned with desire. 


That night, Ava was left stuffed full of a new batch of alien cum, more than pregnant with the next futa alien in the chain. In a few days she’d pop out another huge-dicked daughter, ready to knock her up and help her fill out the ranks of the space rangers again and again and again...
