In the unfathomably distant future, humanity has entered a golden age of intergalactic expansion. Thousands of worlds have been tamed for human settlement, bought with the ingenuity of scientific advancement to preserve and improve human civilization. United by the Interstellar Coalition of Humanity, countless billions of humans live upon terraformed worlds that their ancestors could only fathom as dreams within dreams.
The expansion is still ongoing, projected to easily last for the next million years. Enabled by the use of hyper-drive technology, faster than light travel keeps the disparate colony worlds connected back to the Milky Way galaxy. There have been some splinter groups who moved outside of the domain of the ICH in the millennia since it's founding. But, for the most part, humanity as a whole has remained remarkably uniform across countless generations of diaspora to the colony worlds. Though the definition of what it means to be 'human' has changed drastically with the widespread adoption of biological and nanotechnologies.
One of the core tenants that ties every planet together is the practice of free-use. An ancient cultural practice of free and open sexuality between all people. Young, old, strangers, blood relatives, human or post-human; every individual shares in the freedom of total sexual indulgence. Many highly advanced technologies have only served to broaden the free-use policies of most worlds. Expanding the range of possible sexual partners to previously impossible candidates.
Even as humanity expands across a myriad of worlds, new resources continued to be abundant in the greater cosmos. Unlimited, clean, renewable energy is the standard across the ICH. Robotics and automation have replaced any hard or dangerous labor. Most worlds are self sufficient, capable of sustaining a population rivaling that of old Earth. Each person is free to choose their own path in life; be it exploring the frontiers of the universe, nurturing the next generation, designing the next fastest space ship, creating art in every form imaginable, filling their days with hedonistic pleasures or bouncing between any interest as they see fit.
The need for new colonists on an ever increasing scale has lead many factions within the ICH to create breeding worlds. These are generally some of the oldest and most well-integrated planets in their collectives, set up specifically to produce as many new colonists as possible. Though genetic cloning and mass productions of humans is possible, the costs associated with raising an entire generation of individuals is impractical. The most efficient method is usually to encourage a healthy and productive society on a planet of people who enjoy breeding. The time investment is substantial but on the scale of universal colonization it is just a drop in the bucket.
One such world is Umnara; a temperate, resource-rich planet in the first sector of the Primala galaxy. It has been active as a breeding world for the past thousand years, creating generations of colonists that have gone on to inhabit the surrounding galaxy. The world is in it's prime, vibrant with life and fully capable of remaining habitable for many millions of years. It has not only served as the primary breeding world of the galaxy but also as its central intergalactic hub.
Much of the funding for the Primala galactic colonization process comes from Maxima Polis, an organization dedicated to expanding humanity to the furthest reaches of known space. They seek to ensure the survival of the human species in the event of a galactic scale calamity. Though there is also the incentive of finally finding the holy grail of space exploration; intelligent alien life.
Umnara is by all accounts a paradise. A place where humanity has progressed so far beyond the natural order that it appears to be surreal. The prime directive of its inhabitants is to constantly breed and otherwise live their own lives however they see fit. Technology allows for a universal standard of living totally incomparable to even the most wealthy of their ancestors. The pleasures found here are difficult to comprehend, otherworldly and fascinating. Seek them out knowing that the experience may change everything.
***********************************************************************************************************************************
Naibuna felt her consciousness gently lifted out of a peaceful slumber. The familiar feeling of programs and routines running through her mind. She instantly became aware of all the information that the home system deemed relevant. Mostly morning routines being carried out, daily reminders of tasks, and of course the location of her two bundles of joy.
Not that she needed the computer to tell her where they were. Part of what had woken her up was the movement of their cute little bodies against her own. The large widow's auto-tint slowly turned down, letting light into the room. Naibuna's eyes adjusted and she brushed neon green hair from her eyes to see her little ones already starting the day. The twins were in their own world, happily kissing and sucking around the tip of their mother's semi-hard cock.
Letting out a lusty moan, Naibuna gently moved her hands to drape over each of her children's shoulders. The kids were pressed right up to her sides, all three of them totally naked. Ekizo was on the left, the little guy was eager to please and showed some skill in the double blow job. Eruda was on the right, her long black hair obscuring some of the action. Their mouths danced in near unison around the quickly inflating head of the cock that made them.
"Mmm, morning you two. Ah~" A sizable dribble of precum leaked from Naibuna's cockhead. It was quickly lapped up by the twins as they continued to make out around the bulbous head. It was a bit like a three way kiss between the two nine year olds and their mother's morning wood.
Ekizo popped his mouth from the union just enough to murmur, "Morning."
Eruda cheerfully hummed her response and Nai felt the vibrations travel down her shaft. Letting them continue their wonderful activity, the futa connected back to the home network. A few new messages awaited her. None particularly interesting or important. Nothing newsworthy to integrate from the local or global networks. The house was ramping up nicely, several automated systems were already preparing breakfast and the usual morning necessities.
Done with the system, Nai focused her attention back on her kids. The little tykes were still making out and slobbering all over her now rigid member. A few more spurts of precum had leaked onto their faces, the delicious fluid was swapped between them as their tongues lashed out to clean it. Nai relished the treatment she was receiving and gently coaxed her kids to go faster. It was a nice way to start the morning for all of them.
"I do really appreciate the wake-up fellatio loves, but let's get the day rolling. Who wants to get fucked first?" Nai propositioned her young bedmates.
"Me! Eki got it last before we went to sleep!" Eruda pouted as she looked up into her mother's eyes.
"So? That was yesterday." Ekizo rolled onto his stomach and arched his back, wiggling his cute butt in the air.
"Eki. Remember what we said about sharing?" Nai tousled her son's hair.
"Yeah. I guess." Forlorn, the young boy relented.
"I promise you'll get a turn soon. Eru, how do you want it baby?" Nai gripped her cock in one hand and stroked it passively.
"Doggy!" The girl happily popped up and assumed the position. Her lithe little body twirled around quickly to prepare for the carnal act.
"Mmm, eager little rascal. How about you blow your brother while I fuck you? Get some practice in." Nai got her legs under herself and scooted on her knees to get in position behind her daughter. She slapped her cock against Eru's ass and lower back a few times. The appendage was monstrous compared to the small girl, just over ten inches long and proportionally girthy. Not to mention it was modded to have small ridges along its length when at full mast. A set of heavy testicles hung down loosely in their sack, already full with their first few loads of the day. Behind them hid Nai's pussy, dripping with anticipation.
"Get over here, dingus." Eru playfully tugged on her brothers leg. She was very happy to be getting their mothers cock first but also didn't want her twin left out of the action.
Ekizo mumbled halfheartedly and then shifted position on the bed so his cock was in Eru's face. His tool wasn't quite as impressive as their mother's. It stood at just about four and a half inches tall, no mods beyond the standard enhancement suite. Eruda actually preferred her brother's cock for fellatio as it was much easier to fit in her throat.
Naibuna pulled back her hips and lined up the throbbing tip of her cock with Eruda's sweet little flower which was already sopping wet and ready for action. Some might have described it as 'delicate' but Nai was about to prove why that was not the case. She pressed forward and her daughter's tiny pussy began to stretch widely in order to accept just the head of the invading phallus.
"Fucking fuck, you're so tight baby. You've gotta relax more so I can get inside you." Nai wiggled her hips a bit and popped the first ridge of her cock into her daughter. Eruda was happily occupied sucking on Ekizo's tool, getting the boy to moan and grunt while he ran his fingers through her hair. The young girl knew she needed to relax her muscles, but she loved the feeling of clamping down on every ridge of her mother's dick as it stretched her tiny cunt.
Grabbing Eruda's small hips firmly, Naibuna pressed harder to speed up the process. She knew that it was nearly impossible for her to even come close to hurting her daughter this way. After all she'd been fucking both twins for a few years now. The elastic nature of bio-engineered flesh was incredibly resilient when it needed to be. That was barely even considered a modification in the current age, everyone could take almost any sized phallus comfortably.
After quite a bit of prompting and squeezing Naibuna finally bottomed out inside Eruda. The futa mother exhaled deeply and closed her eyes. The relief of finally being fully enveloped by a hot, wet hole was divine. The little girl was utterly stuffed, packed with ten inches of futa cock that bulged her stomach slightly. She whimpered around her brother's dick. "Shoooo fulllll....."
"Nnnnghh. I'm gonna pump a little bit now. Keep steady." Nai gave a slight warning before pulling back. She had to put some forward pressure on Eruda's hips just to get the leverage to extract her cock from the girl's vice grip hole. A few of Nai's ridges popped free before she pressed back in, a bit easier this time. That pattern continued for a few strokes. Deliberate repetitions of easing the massive tool in and out of a tiny sheath.
Finally feeling her daughter really loosen up, Naibuna opened up the throttle a bit. She pumped with more gusto, slamming home on each forward thrust. Eruda's gooey pussy took the treatment in stride, making wet squelching noises around every ridge. Nai closed her eyes and tipped her head back, really getting into the rhythm of pounding her little girl.
"Mooooom! Eru's not sucking me good anymore!" Ekizo grabbed his sisters hair and pulled her head up, looking into the face of a girl completely drunk on pleasure. Eru was cross eyed with her tongue hanging out, getting stretched by large dicks often turned her into a empty-headed fuckdoll.
Not even remotely slowing her pace, Naibuna sighed. "I thought she'd gotten a bit better at keeping it together. Just fuck her face honey."
Ekizo bunched up Eruda's hair and got a good grip on the back of her head. He fed his cock into her open mouth and then thrust his hips up to force it deeper. Eruda was vaguely aware of the new sensation but was still enraptured by the euphoria caused by her mother's ribbed monster rearranging her insides. Her orgasm was quickly building to a earth-shattering high.
Closing her eyes again, Naibuna indulged in one of her favorite habits. She reached her mind out to the home system and found the path to the cameras. Selecting the micro unit on the wall just a few feet away, she was instantly treated to a third-person perspective of the threesome she was a part of. Ekizo was humping into Eruda's mouth with enthusiasm. The young girl was sandwiched between her mother and brother, taking their rough treatment like a champ. Nai loved the surreal sensation of moving her body and watching the action happen in real time. Plus the cameras could be moved at will, extending her range of viewing angles immensely.
Swinging the camera around, Nai caught sight of someone masturbating in the doorway. She dismissed the system and turned to look over her shoulder. "Are you going to join us or just having fun watching?"
"Well, you know how much I enjoy watching you fuck our kids. Especially when Eru turns into a cute little cock-sleeve around your big daddy dick." Slevne sauntered up behind Naibuna and wrapped her arms around to cup the futa's firm breasts. Nai groaned appreciatively and kept drilling their daughter's tight pussy. Slevne lightly pinched Nai's nipples and glanced around the muscular futa to see Ekizo doing his best to use Eruda's mouth to get off. "Morning sweetie. How's your sister's mouth doing for ya?"
"Morning mom. It's okay I guess." Eki roughly maneuvered Eru's head up and down his cock, the girl a giggling mess while being spit roasted.
"Hmm, do you want to use my holes instead?" Slevne pulled away from Nai to swivel around and spread her ass cheeks. The blonde woman was well defined, with a plump rear and hourglass curves. Her exposed holes were familiar and inviting to the young boy.
"Yeah!" Ekizo pulled his wet cock from his sister's mouth. Eru slumped forward and began to moan freely now that her mouth was unoccupied. Mother and son got onto the bed next to the other rutting pair, Slevne laying on her back and Ekizo lining up his dick with her dripping cunt.
"Unghh. Good boy~ go as fast as you want." Slevne cooed at her son as he slipped into her pussy and began to move his hips. His thrusts were not nearly as powerful as Naibuna's, but he was eager and enthusiastic. Slevne looked over to her daughter as the young girl continued to be utterly mind broken. She softly cupped Eru's face and kissed her gently.
Meanwhile Naibuna and Ekizo were happily pounding away at the pair of mother-daughter cunts. Nai had fully stretched out Eruda's tiny hole and was heartily giving the little slut a proper pounding. Her small frame jerking forward with each strike. Eki reached forward to grope Slevne's sizable tits as he made them jiggle with small but mighty thrusts.
"Not just back and forth, Eki. More of a rocking motion with your hips, like this." Nai modeled the movement slowly, her fat meat sliding effortlessly in and out of her daughter's stretched pussy.
"Mhm." Ekizo momentarily concentrated on his movements and imitated his futa mother. Though his minds was a bit too hazy to really get it down. Fucking was an art form, one that could be honed over centuries of refined training and practice.
Slevne moaned into her daughter's mouth as her son got into a rhythm of really stirring up her insides. Futa and son were almost in sync now, plowing their ladies with redoubled effort. Moans and the rhythmic slapping of skin was all that could be heard in the bedroom. Nai drifted back into the system and picked up her camera view. She adored how Eki was so inexperienced with his technique but still doing his best and wanting to please his mother. She logged the footage for future review.
"Haaaaa... I'm... gonna... cum!" Eki began wildly swinging his hips. The young boy hadn't quite mastered a 'simple' orgasm yet. Every time he came the experience wracked his mind with intense pleasure, leaving his body running on base instincts. Slevne was just happy to have her little boy giving it his all. She adored feeling his immature cock swell and pump fresh boy cum straight into her greedy pussy.
"Guess we'd better wrap it up." Nai heartily slapped Eruda's ass and shoved all ten inches of her ribbed cock into the mind-broken girl. She grunted and triggered her own orgasm, using several mods to adjust the amount and viscosity of her semen. Her balls twitched as they pumped a few powerful spurts of extra thick spunk deep inside Eruda. The eight year old had been cumming nearly continuously while she was being violated. But the feeling of that hot load being blasted right against her womb sent her into true euphoria.
The orgasm was nice for Naibuna, but the modded mental trigger never felt as good as a more 'natural' buildup and climax. She pulled her cock free from her daughter's gooey cunt and admired the scene. Eru and Eki were both spent, twitching bodies and loopy smiles a testament to their fun. Slevne rubbed Ekizo's back as he lay atop her. She caught Naibuna's eyes and opened a direct link between them.
I do so adore our family time, but the little ones need to be at school in a few hours.
Sure, sure. Showers are running now. I'll take Eki and get a head start. You can help Eru recover. Nai knew she'd gone a bit overboard while fucking her daughter but the little siren was just too alluring sometimes. Even now, her pussy was almost back to it's original shape and tautness; tempting the futa to ravage her all over again.
"Okay buddy. Up ya go." Nai easily hoisted Ekizo into her arms and cradled him like a small baby.
"Mom I can walk." Eki blinked back post-orgasm weariness.
"I know. You're such a big boy now. Soon you're going to be getting your first mods and then knocking up your first breeding dame and then graduating and then building your own homestead or maybe finding work off-world. You're only going to be my little boy for so long." Nai kissed his head.
"Mom, stop it!" Ekizo sheepishly nudged her chest while she walked to the shower. The tall, muscular futa set her son down and playfully slapped his ass.
"Get in there and start washing yourself up. I'll be along soon." Naibuna smiled at her little boy as he trotted behind the fogged glass of the shower wall. Turning her attention to the nearby mirror, Nai took a moment to admire her own body and figure out her hair color.
The prevalence of mods in human culture had been a slow growing process at first. The first gene editing technology had been used to cure or stave off terrible diseases. Once that had been mostly perfected and the tech was commercially available, the uses were still limited by an old-fashioned notion of 'biological humanity'. That humans needed to stay close to their evolutionary roots, to not adjust the homo-sapien form in drastic ways.
This was, of course, very quickly quickly cast off once the full capabilities of bio-engineering came into their prime. Humans could be born with stronger and lighter skeletons, more resilient and intelligent immune systems, drastically more efficient and robust organ systems, as well as enhanced senses and stamina. All of which greatly contributed to longevity and quality of life for every person over thousands of years. Integrated with blossoming nanotechnologies and boundless human creativity, biological engineering had caused more profound and widespread changes than any previous advancement. Perhaps save for the faster-than-light engine or agriculture.
This was all ancient history now, barely an afterthought in the modern age. The norms of intergalactic society had radically adjusted countless times in the eons since humanity had left its home planet. Many worlds were at least recognizable as being inhabited by majority of 'human-like' beings. Others were far outside the realm of any imaginable alien world. The sole unifying feature of the human civilization was adherence to the free-use principles that dated back to before recorded history.
Naibuna focused on her own internal network and let the mods do their work. Her hair changed from neon green to pure white then flashed a dazzling display of multi-colored patterns. An explosively fast exhibition of possible options that Nai sorted through with ease, searching for the right fit. She decided on a lovely deep purple hue with brighter pink highlights. She adjusted the length by a smidgen, just enough to brush her shoulders, and found that it looked wonderful. She'd never had the same hair color for more than a day since she'd gotten the mod when she was young.
Done with that small routine, Nai wandered over to the fogged glass wall and peered behind it. Ekizo was dutifully scrubbing himself clean under a torrent of water from the shower head. The mechanical arm it was attached to could be oriented in any way with a simple thought, the pressure and temperature of the water likewise. There were two more such shower heads in the spacious area but Nai decided to share the one her son was using.
"Want me to help you, baby?" Nai ran her hands over the boy's shoulders as she stepped into the stream of hot water with him.
"Okay." Eki handed her the soapy scrubber. The pair spent some time enjoying the water and giving each others bodies a thorough cleaning. Of course there were automated ways of self-cleaning but this manual method allowed for more erotic affairs. Nai and Eki both pampered the other with gentle caresses and firm grasps, letting the soothing experience arouse them both once again.
Nai's cock was almost at full mast, pressed against Ekizo's chest as the young boy kissed her chiseled abs. A very welcome feature of a particular mod that Nai enjoyed, boosting her physique to have 'amazonian' qualities. The futa was a vision of muscular beauty despite putting in barely any effort to maintain her body, the mods did most of the work.
"I did promise you a turn this morning. Wanna jump on now?" Nai gripped the base of her cock and slapped the length of it against Ekizo's chest.
"Yeah!" Eki was also hard again, his smaller tool poking his mother's lower thigh.
Nai mentally commanded a section of the wall to extend outward, creating a perfectly ergonomic and sturdy seat. The micro-textures of the material quickly adjusted to be water-repellent and have great traction to prevent slipping. The futa sat down and reclined a bit, adjusting the chair a bit more to accommodate for Ekizo. The little boy slid up onto his mother's lap and moved in to kiss her, their wet cocks sliding against each other.
Knowing that they only had so long to work with, Naibuna reciprocated her son's passionate kiss but also worked her hands under his butt and pulled him upward. Much the same as with Eruda, Nai lined up her bulbous cockhead with Ekizo's tight hole and gently let him down. Eki moaned into his mother's mouth as his tiny asshole stretched to accept the invading phallus. He'd taken it many times before, to the point that he'd long since lost count, but it was still a tight challenge.
Naibuna did her best to not thrust up into her son. The little guy needed to take his time and stretch out properly. She broke their kiss and moaned deeply while rolling her head back. "Such a good little slut. Take that cock all the way. Fuuuuck that's it, good boy."
Ekizo finally pressed himself all the way down and connected with Nai's hips. The futa cock that made him was bulging out his stomach slightly. Human-standard mods meant that every orifice was capable of remarkable stretching and self-lubrication. Something Ekizo was hardly even aware of, to him this was just the natural way he fucked his mother.
Naibuna's cock ridges popped out of Ekizo's tight sphincter one by one as the little boy began to rock his hips, aided by his mother's loving arms. They continued to gently rock up and down, trading tender kisses and sweet whispers. Hands slid effortlessly along slick skin, cupping and pressing against everything. The warm water was running nearby, creating a pleasant rumble of noise to mask the sounds of incestuous love.
"Mommy, I'm close." Eki murmured into Nai's neck. The futa hummed her approval and pressed both of her hands down onto her son's ass. A quick thrust lodged her entire length inside him, causing the young boy to squeak and tremble. His cock swelled and then shot several ropes of cum between their bodies, mostly on Nai's tits and abdomen.
Drained for the moment, Eki rested all of his weight onto his mother's body which he'd just pained with boy-cum. Nai rubbed his hair and let him recover. Two morning orgasms would keep him satiated for the time being, at least until they got done eating breakfast. As much as Nai wanted to keep going until she had her own proper orgasm, they were on a schedule.
Helping the little tot to his unsteady feet, Nai got them both rinsed off once more. Just as they were done, Slevne and Eruda entered the shower. The mother-daughter pair followed a similar routine, beginning to scrub together under the shower head. Nai nudged Eki along to get them to breakfast, the young boy seemed like he wanted to watch his mother and sister.
They need to be at school soon, yeah? Don't spend too long feeling up our little girl. Nai teased Slevne over their private connection.
As if you're innocent. Start eating, we'll be there soon. Slevne let out soft moan as Eruda's little fingers penetrated her cunt.
A few seconds in the thermal chamber left both Naibuna and Ekizo as dry as a sun-baked landscape. With strict instructions to get ready and head downstairs, Ekizo scampered off to his room. Naibuna similarly returned to her room to find the bed perfectly made with fresh sheets. The work of the housekeeping automations. Glancing into her closet, she picked out a simple outfit for the day. Just a pair of tight black shorts that stretched around her package and an open leather jacket that barely went down to her midriff. Her style was usually punk or alternative, as the old fashion trends went. She'd had a few body piercings for several years but found them annoying during intense sexual situations.
Downstairs, things were looking lively. Ekizo energetically ran up to the large dining table and sat next to his older brother, Gerno. The food on display had been freshly synthesized by the kitchen automations. There was a large variety of items including fresh fruits, warm breads, eggs prepared in multiple different ways, and a multitude of combinations to make any dish from across a thousand worlds.
"Morning Eki. You ready for school?" Gerno sipped some hot tea and nudged his little brother. The two sons were both the product of Naibuna's potent seed, along with a few dozen siblings. Though they had different maternal lineages, the brothers were fairly close.
"Yeah! We're gonna get ready for the beginner orgy today." Eki spoke while shoveling scrambled eggs into his mouth. He was wearing a simple white skirt that came down to his mid-thigh and a matching sheer crop top. The boy like to dress a bit more conservative, not letting everything hang out.
"Oh, that's coming up huh? I remember doing that, it was super fun. I'm sure Mom is looking forward to it as well." Gerno was several years older than the twins, just on the cusp of adulthood. Not needing to go anywhere this morning, he was totally naked at the dining table. His body was lean and well toned with a few tattoos marking his flawless skin. Between his legs hung a pair of flaccid cocks that were identical in every way. It was a rare mod but one that worked very well for him.
Both brothers felt something nudge their legs. A warm body pressed itself between them and an adorable face popped out from underneath the table. "Mrrroww~"
"Kolful, I just got you breakfast and gave you your morning fuck. What is it?" Gerno scratched between the catgirl's fluffy ears. Her tufts of fur were bright orange and exquisitely soft. Kolful purred while glancing between the two brothers.
"Morning loves. Is our kitty being a little nuisance again?" Naibuna kissed both her sons' heads before pulling out a chair from the table. She assembled a plate of food and dug into it.
"No, just needy. She's really cute when she wants to be though." Gerno patted Kolful on the head and went back to finishing his meal. The catgirl gave a few more dejected meows before retreating to her custom cat bed, tail swishing forlornly as she went.
Just as everyone was finishing their food, Slevne and Eruda finally arrived. The pair were obviously rushed but still looked good for the morning. Slevne had thrown on a simple blue g-string and loose shirt combo. Eru was a bit more elegant in a strapy black body harness made of smart-compression threads. It weaved around her small body tightly, down her thighs and even into a collar around her neck. Her nipples were barley concealed and her pussy was only covered by a lacy thong.
"Morning everyone." Slevne scooted into her seat, quickly making up a place and helping Eru as well. "Nai, I think you should take the kids to school today. Seeing as you're the reason we're running late in the first place."
"Alright. Not like we're that late anyway." Nai smirked at Eru and Eki. The twins returned the gesture with their own mischievous grins.
"Why do I even bother." Slevne suppressed a grin as well.
Just a few minutes later Nai was clapping expectantly to urge the twins along. "Shoes, now. Move your little asses." She slapped Eru's tiny behind, a faint echo of the rough pounding she'd given the girl earlier.
"Mom, do we have to wear shoes?" Eru grumbled as the smart-fabric molded to her feet.
"Yes. At least until you can get enhanced durability mods." Nai slipped on her own heavy boots.
"Have a good day at school kids! Love you!" Slevne shouted from the love-nest in the other room. Kolful had cuddled up with her and the two of them were slowly building up to some steamy sex. The twins called back with their own well wishes, giddy childish voices ringing through the house. Eventually they were corralled into the entrance corridor with some persistent influence.
"And we're off." Nai triggered the front door of their house to swing open, her cock already hardening at what she and her kids might encounter in the wider world of Umnara.
