Invasive Species
Inspiration taken from Zdemian’s Invasive Species comic.
The only imperative of the empire was growth. Bigger was always better, in every sense – the empire spanned the galaxy and was still adding more member planets every day; its shipyards competed to outdo themselves in the size and majesty of the immense luxury worldships, each home to millions of citizens; and even on a personal level, every good citizen of the empire considered it their personal duty to be the best and brightest they could be.
And, in a very literal sense, the biggest they could be. A womb not absolutely stuffed with new citizens was a womb that was going to waste. And over the centuries, the empire had gotten very, very good at making sure its wombs were productive.
“Initial scans indicate a pre-interplanetary biped race, on a planet with point 76 standard G and abundant water resources. Genetic testing within normal limits; we should be compatible. Our appearances are within three standard deviations of average and should be sufficient to not arouse attention.”
“Does that mean I can fuck ‘em?”
“…Yes.”
“Sweeeeeeet!” Lola shimmied with pleasure in her silvery jumpsuit, setting her enormous rack wobbling. Six-foot-five, Lola was a born-and-bred breeder of the empire, her beachball-sized breasts overshadowing her loveseat-sized hips. This was her first long-term survey mission after a decade serving as a breeder on a worldship, and the wait between planets (and available male companionship) had been almost unbearable. If they’d ended up at another asexual backwater, she likely would have gone mad with breedlust before much longer.
“They have discovered generalized computing, so we are working to establish a front identity and forward base for you and the rest of the team. Habitation scales seem large enough to install a proper incubation and training room…” Lola tuned out the paperwork-pushing functionary. She was too busy dreaming about how much dick she was finally going to get after such a long wait!
Lola licked her lips as she sauntered down the street, her absurdly sexualized form attracting stares and gaping mouths. Not that she cared; her only thought was how yummy all the “human” studs looked. For a race previously uncontacted by the empire, they were quite easy on the eyes, and Lola’s pheromone-sensitive nose had been recalibrated before arrival to select for only the most virile of candidates.
She caught a particularly enticing whiff of sex hormone and followed her nose to an outdoor cafe, where a young male sat sipping some sort of hot beverage. “Hey there, hot stuff,” she said, leaning against the table, one of her massive breasts completely covering the book he had been reading. “I’m new in town and could use some help getting around.”
“I, uh… I could probably, uh, show you around a bit,” her hapless target said, eyes practically popping out of his skull.
She smiled, wrapped herself around his arm as he stood up, and subtly guided him back toward the house the empire had purchased a few blocks away.
“…oh, and look, this is where I’m living now! Could I invite you in to thank you for your help?”
She started stripping him down the moment they were inside, and she finally got to unwrap her present. “Ooh, it’s so big,” she cooed as she pulled off his underpants. Her nose hadn’t been wrong – a full ten-inches and rock-hard, impressive indeed for a non-empire citizen, even if she’d have been disappointed and contemptuous if such a cock had been presented to her aboard the worldship.
But there was time for that later. For now, she simply pushed him onto his back and mounted him, guiding his hands up to knead her enormous breasts as she ground away on his turgid pole. Her dick-craving snatch milked him for all he was worth, and within minutes he’d come to a massive, shuddering climax, as was to be expected – no male could resist a breeder of the empire.
His stamina was impressive, however, as she coaxed two more blasts from him, less powerful than his first but still respectable. Inside, she grumbled slightly as she felt him flagging – but that wouldn’t be a problem for long, and he had performed well for his first time with a breeder like her.
“You’ll do just fine,” she said, smiling at his passed-out form, and carefully closed the control collar around his neck.
Lola lay back on her special couch and smiled. Her first pick had done more than fine, it turned out; humanity’s virility was the strongest ever recorded, even more impressive than some empire species that had been frog-marched down evolutionary pathways designed to turn them into sperm-producing machines. The training staff had been overjoyed at the raw material humans represented, and worked overtime to turn Lola’s first recruit into a true citizen of the empire.
Lola’s womb, however, had wasted no time kicking into high gear. Within a week, she had started expanding rapidly, and now, a month after her first conquest, her belly already outsized her enormous breasts; she looked for all the world like a woman who had somehow stuffed three titanic beach balls into her body and was walking around like it was no big deal.
At this point, the training staff returned her boy-toy back to her, fully converted, and she celebrated by having him fuck her gravid body into a ear-piercing orgasm, his beefier body hugging tight to her titanic belly. The trainers had done wonders with his cock, growing it from a pleasant little ten-inches all the way up to a hip-shattering forty inches, and as big around as her thighs. That was a cock, as Lola knew them – an endowment that would have placed him in the upper quartile of empire citizens, and a true imperial pussy-pleaser.
He grunted and came, flooding her with semen, and her ovaries reacted, releasing more eggs to push her gravid state even further. She came again and again as she imagined being fucked until she was as big as the house, as big as the imperial scout ship she’d come here in, as big as an entire worldship – a breeder like her could never be big enough!
She patted her titanic belly and giggled lightly. Her little pet was still standing there, erection still rock-hard and slapping against his chest in time with his heartbeat. She already felt bigger, and knew that if she had her way she’d be fucking this human until she couldn’t stand any longer – already a concern, even with the light gravity of the human homeworld.
“It’d be worth it,” Lola said, grinning, and the human grunted.
“Very impressive,” the functionary was saying to Lola, who was only half-listening again. “All of this from one enhanced human?”
“Originally not even enhanced,” Lola said, patting the slope of her belly with pride.
There was a lot of belly to pat. Lola’s fantasies of immobility had quickly come true, but that just meant she was transferred back to the scout ship, which had plenty of space to contain a rapidly-growing breeder and her favorite new alien.
And she was indeed still rapidly growing, now five months post-contact and with a belly that far outweighed the rest of her. Even one of her breasts dwarfed the rest of her body at this point; she had become what many in the empire’s breeding corps dreamed of being: “a walking womb”.
Not that she was doing much walking these days. A belly that literally stretched twenty feet in front of her saw to that. It was impossible to tell precisely how many new citizens of the empire were gestating inside of her, but the ship was being rapidly retrofitted to provide nursery space for all of the newborns local humans very adept at stuffing Lola and her fellow breeders with.
The functionary gave the human a once-over as well, noting the impressive cock size and complete servility. “The trainers tell me they’ve been refining the process as they take in more humans, and plan on being able to easily surpass this size on future recruits,” she said, making Lola’s insides squirm in anticipation of the future flood of even more satisfying cock.
The functionary eventually left, and Lola gestured lazily for her boy-toy to come over and fuck her again. At this point, she was as pregnant as she was going to get, but that didn’t mean that she didn’t enjoy having her absurdly fertile vagina filled to the brim with an enormous cock every chance she got.
With the gravity turned nearly to nothing, Lola closed her eyes and spread herself out on her belly, imagining that, instead of merely being the size of a large van, she were lying on a vast planetoid that was nothing but her stupendous womb, filled with as many new citizens as every other breeder in history had ever managed to birth. She was a legend, a queen, the most fertile breeder ever, worshipped with a succession of the biggest, fattest, most virile cocks in the galaxy, sandwiched between her tits, thrusting into her womb, stuffed into her mouth.
She came again and again, shuddering and yelping as her human pounded into her. “More! More! Mooooooore!”
In the empire, after all, bigger was always better.
