Ricca lightly strolled up the somewhat lengthy driveway of her sisters home. She was flanked by two of her children, Revu and Mu. The trio had made the journey to Naibuna's estate by air train and arrived just after dawn. All three had been fucked in various ways during their trip, nothing out of the ordinary for public transportation. Though the sex had been satisfying, it was just casual fun to occupy time on the intercontinental journey.
The breeder matriarch was wearing a simple red slip dress which draped off of her shapely body. It showed off a good bit of cleavage without being overly slutty. Revu followed in a similar vein; wearing a very light, loose pink romper with a floral pattern on it. Mu drifted a bit more toward the overtly sexual side of things. A set of shiny, amber colored, skin-tight shorts covered their bulge but the rest of their starry night-sky skin was on full display. The cosmic enby was roughly ten years old, though it was hard to tell with their heavily modded body.
"Do you know what the twin's new mods are mom?" Revu plodded along the driveway, hands behind her back and leaning forward. Her chest strained the fabric of her top slightly.
"I have no idea love. That should be a very nice surprise. Though I do imagine that the twins are still getting used to their new bodies. No need to rush them into anything." Ricca reminded her daughter.
"Mhm. I'm just very curious is all."
"No harm in that. And are you ready for your little quest today Mu?"
With a voice like a layered set of harmonies, the young child replied. "I am. I appreciate the help."
The small group made their way up the driveway and approached the door. It slid open with a simple command from Ricca. Letting themselves in with no fanfare, the trio wandered toward the dining room. There they found two individuals who were elated by their arrival.
"Oh, this is a welcome surprise! It's lovely to see you all!" Slevne threw a hand up in an enthusiastic- if limited- gesture. It was harder for the heavily pregnant woman to rise from her chair. She was wearing a thin white robe, untied and fully open. Between her widely spread legs a vibrating dildo was lodged deep in her pussy. The faint humming of the toy could be clearly heard by everyone in the room.
"I'm glad you could make it. The twins will be so happy to play with you all." Naibuna rose to hug her sister-wife and daughter. The only piece of clothing she had on was a black sports bra, leaving the rest of her muscular figure bare. She had chosen yellow, shoulder length hair today. Bright colors always accentuated her bronze skin. Her flaccid cock hung right at eye level for the young Mu, who was entranced by the swaying rod. "And I remember you little one. A beautiful cosmic child. Mu, yes? What brings you to my home today?"
Mu straightened their back and sheepishly looked up with pure white eyes. Their starry night-sky skin twinkled slowly, dazzling in it's cosmic brilliance. Mu's voice was a mixture of several layers, each a very distinct range that all melded harmoniously to create a discernible cadence. "I would like to have very rough, primal sex with you."
Ricca elaborated. "Mu has an assignment from school to practice being roughly dominated. Hardly anyone at home can give them a real hard-core fuck so I suggested they tag along today. I know you can be such a big strong primal lover."
"I suppose I can help. Why don't we chat a bit and get started after breakfast?" Nai smiled warmly. Mu agreed and sat beside the much larger futanari at the table.
"Revu, sweetie, could you call everyone upstairs down for breakfast? They're resting up after the fuckfest we had yesterday in celebration of the twins new mods." Slevne gently suggested. One of her hands went to her breast and massaged it.
"Sure. I can't wait to see what they chose."
"Go find out then." Slevne winked.
Revu climbed the stairs two at a time, scampering quickly to investigate the alluring unknowns. Most of the rooms on this floor had their doors open, so she was free to explore. The first room she came to- Naibuna's- was uninhabited. The teen futa skipped with light footfalls over to the next room, her bust bouncing slightly with each hop.
The next one over was Gerno's, which Revu peaked into inquisitively. She saw her brother peacefully slumbering on his bed, spooning their little sister Eruda. Gerno had an arm wrapped around the small girl in a loving embrace. They were completely nude and just had a light cover thrown over their lower bodies. The two had obviously been fucking late into the night and were still slumbering sweetly. Gerno's twin cocks were undoubtedly nestled between Eruda's legs. Probably soft but primed to harden whenever he awoke to find his little sister's body pressed into his own.
Eruda did not appear any different than Revu remembered. But that hardly meant anything. There were hundreds of mods that were all but invisible to the naked eye. Things that could drastically change a person's capabilities in a myriad of ways. Revu knew that Nai had encouraged the twins to start small, just as she had with Revu's own first mods. There wasn't going to be a totally new body-plan for either of the kids. The thrill of discovery was more about uncovering why the twins chose the mods they did and how it would give them new experiences.
Aww, they're too cute! I don't want to wake them. Revu decided to let the couple rest a bit longer and moved further down the hall. She encountered a few more empty rooms before finding another sleepy snuggle pile. Ekizo, Kolful and a young futa Revu did not recognize were all cuddled together on Eki's bed. Kolful was in the center with a child on either side, their faces nuzzled into the catgirl's breasts. The trio had no coverings, their bodies laid bare to the morning light.
It wasn't all too uncommon to find a stranger in bed with your relatives, people often brought home new friends or quick flings. It was common courtesy to treat strangers in family homes like special guests. Often the newcomers would end up having far more sex with the family members of their intended partner than the partner themself. Revu quickly glanced at the system information of the new futanari. Ahhh so this is Yenzl, Eki's new mistress~ Cute!
Through the system interface, Revu gave a gentle mental nudge to all three people on the bed. Instantly, they began to stir and stretch. Ekizo groaned and pressed his face into Kolful's side, just under her breast. Yenzl more elegantly raised her head and blinked away some confusion. "Oh, hello."
"Hello there. I'm Revu, Eki's sister. I'm visiting for the day. Breakfast will served soon for those who can wake up in time." Revu poked fun at her little brother who was still clinging to Kolful like a weary kitten.
The much larger catgirl awoke with a deep purr and stretched her long, flexible body to the limit. She trembled at the apex of the stretch and then relaxed, moving her muscles and joints a bit to get them ready for the day. She nuzzled the heads of each of the children at her sides before pulling herself up and out of the bed. Eki mumbled something incoherent but did stretch and crack his eyes open.
"That sounds lovely. I am famished after what occurred last night. Beloved, it is time to awaken." Yenzl gently reached out to stroke Ekizo's abdomen. Revu noticed that his cock was still fully erect, even after a night of non-stop sex. Yenzl, by comparison, was soft and showing no signs of arousal.
The young couple embraced sweetly on the bed as Kolful brushed up against Revu, purring and swishing her tail. "It's good too see you too, you big baby. Who's a good girl? Who's a very, very good girl? You are!"
Revu leaned down to pet the catgirl who reveled in the praise and attention. Even being decades older than Revu, Kolful was still just a pretty baby who thrived on the adoration of everyone around her. She craved it almost as much as she craved sex. In her human mode, it was difficult for Kolful to admit she had a praise kink but in kitty mode she actively sought it out.
After doting on the catgirl for a moment, Revu reminded the lovebirds to be downstairs soon and returned to the hallway. This time, as she approached Gerno's door, she could hear the faint sounds of early morning pleasure emanating from the room. The futa turned the corner to see her siblings engaged in a slow but firm bout of sexual intercourse. They were still spooning but now Gerno had both of his cocks planted into Eruda's young holes. He gyrated his hips steadily, making a very subtle pumping action into his sister's body.
"Hi guys. Breakfast is going to be ready soon." Revu commented offhandedly as her own cock hardened in her romper. She reached down to readjust it.
"Mmm. Yeah, we'll be there." Gerno groaned softly. "Revu you gotta try Eru's holes now, they're fucking divine~"
Eruda giggled mischievously. "Yeah! I'm super stretchy now and I can do fun stuff. Watch." The little minx did something causing Gerno to stop moving his hips and let out a long breathy moan. His hands dug into Eru's little body as she reached up to caress his face. The two siblings were locked like that momentarily, Eruda smugly showing off her new skill as Gerno experienced ecstasy.
"That looks very pleasurable, Eru. I'll be sure to partake of your new body soon. Breakfast, don't forget." Revu reluctantly left the two to finish their morning tryst, knowing she'd get some time with both of the twins eventually. The plan was for the three city dwellers to be at Naibuna's residence for the whole day. Revu had spent the majority of her younger years in the city but had also made regular trips to be with Nai at her estate. The young futa ultimately felt at home in either location.
Downstairs in the dining room, Ricca and Slevne were engaged in a conversation about the upcoming live music events at the Stratus Station. Both women enjoyed going to large concerts and were formulating a plan to see a show together. Across the table, Naibuna had pulled Mu close, wrapping and arm around the child's shoulders and conversing with them intimately. Revu found a seat as she was trailed closely by Kolful who sneaked underneath the table. The catgirl wandered a bit down there, snuggling and curling her tail around legs as she went.
Over the course of several minutes, the remaining household members and guests made their way downstairs. Ekizo wore only a tight pair of black briefs which were still tented by his hard little pecker. Yenzl was borrowing a large white shirt from someone, the over sized garment looked comical on her slender frame but did cover down to her thighs. Eruda skipped into the room, still nude, followed by Gerno who had put on some shorts and a shirt.
There was enough room to fit everyone at the table, if just barely. Nai was glad she didn't have to make more space to expand the table as that would only complicate things. The group made lively conversation as breakfast was served. Ricca commented a few times on the quality of the synthesized food, saying that it never tasted quite the same as hand-made dishes. Revu only somewhat agreed with her mother as she did enjoy her cooking but could barely discern a difference in the foods. Gerno filled in everyone on how his long term plans were coming along. He was planning on finding a specific branch of physics he was interested in studying and then traveling to a research station for that, possibly in a different galaxy. And he was still searching for a partner or two who would be interested in that journey.
Yenzl politely chatted with Revu and Eruda while she reached inside Ekizo's briefs to give him a slow hand job. The boy gave a small moan through a bite of food, allowing his mistress to play with him whenever she wanted to. He tried to focus on eating as Yenzl freely massaged his hard cock under his tight briefs. Even moving down to fondle his balls a bit as the meal continued.
"Eki, how are you feeling with the new mods?" Slevne directed some attention to her son.
"Mmm, horny." Eki relaxed back in his chair. Yenzl smirked at him and tightened her grip around his erection.
"Show everyone your new tongue love." Nai interjected. Eki obediently opened his mouth and let his tongue slide out. It kept sliding, extending to about seven inches long. Its tip split apart suddenly, allowing the first two inches to become independent prehensile appendages. It appeared to be some kind of squishy tentacle made of a human tongue. Eki clumsily contorted his tongue around a bit, showing off how it could move and twist in the air. His muscles had been augmented to allow him much better control of his new organ but he was still getting used to how it worked.
"Fuck. That's… incredible." Ricca placed a hand on her chest as her breath caught at the sight of the long writhing organ.
"I let him practice eating me out for two hours last night. I cannot even begin to tell you how good it feels. Eki was already very talented with his tongue, this is taking it to a whole different level." Slevne gushed over her son's oral abilities like a proud mother.
"Yes, my good boy is a real menace with his new tool. His blowjobs are ten times what they used to be." Yenzl was still gently stroking Eki's member.
"If that's the case, I'll be sure to offer myself for even more practice then." Ricca cooed at the young boy. She leaned over the table slightly, cleavage pressing against her dress seductively.
Eki slowly pulled his tongue back into his mouth (it was difficult for him to speak with it fully extended). "Thanks, I wanna get a lot better."
Eruda was the next to show off, this time in the form of a video she shared with everyone. It showed the little girl laying in her bed as Slevne gently pushed an extremely girthy horse dildo into her stretchy cunt. The toy was easily thicker than Eruda's thigh and made to look very realistic. A large bulge pressed it's way up her abdomen, making the girl squirm and thrash on the bed. "And I want to take a real one now! I'm gonna meet up with a guy from the net who's got a bigger horse dick! Stretch my pussy to the limit!"
"That's crazy! Send me the video of that for sure!" Revu was impressed by her little sister's size queen behavior.
The rest of breakfast was relatively uneventful. Kolful got impatient after her own meal and forced her way between Gerno's legs, nuzzling her face into his double bulge. She passionately licked all over it while mewling desperately. Nai gently reprimanded the kitty for being such a needy cock slut. Even so, Gerno snuck two fingers into the catgirls hot, wet cunt as everyone was finishing up their meals.
"If anyone needs me, I'll be enjoying this hot piece of ass in the love-nest." Nai announced as she easily hoisted Mu into the air and slung them up over her shoulder. The small starchild giggled as they were hauled around like a sack of produce. Mu had consented to basically anything Nai wanted to do to them. The purpose of the oncoming sexual blitz was to get Mu more accustomed to being roughly dominated in as many ways as possible. The rest of the family and guests watched as Nai carried off her 'prey' to the other room, her hard cock swaying freely the entire way.
"Alright you needy little cunt, now we can get at it." Gerno pulled his fingers from Kolful's snatch and licked them clean before grabbing her by the neck and pulling her up. He turned the purring catgirl around and made her bend over the table, presenting for him with her tail swishing over his chest. Quickly letting his shorts fall, Gerno lined up both tips of his cocks with Kolful's holes. He thrust forward and sank several inches of both of his shafts into the mewling cock slut. Kolful panted and writhed on the table, shoving some plates and cups out of her way. Her long tail wrapped around the back of Gerno's neck, pulling him in closer. The sounds of their fast coupling quickly overtook the rest of the mundane breakfast noises.
"Mmm, your brother looks quite nice when he fucks. I would like to take him at some point today. Getting double penetration from one person is a unique experience." Yenzl leaned over and wrapped an arm around her concubine's shoulders.
"He is cool." Eki commented as they watched the continuing fornication on the table mere inches away. The boy had taken his brother's cock before of course, though only in the singular sense. He only had one hole down there so the sensations of a double penetration were foreign to him. Maybe it's like getting spit-roasted? That feels good. Eki pondered the mystery.
"Yenzl, if you wouldn't mind, I'm dying to experience the tongue of your lovely concubine." Ricca approached the two young lovers from behind, placing a hand on each of their shoulders. Eki swooned at being called Yenzl's concubine, especially by his aunt who'd known the boy since he was born.
"Oh, of course! Shall we retreat to one of the bedrooms then?" Yenzl was more than happy to share her sweet boy but she did want to join in on the experience as much as possible.
"Perfect." Ricca ushered the two youngsters up the stairs and into Eki's bedroom.
"Eruda, do you want to join anyone or should we play by ourselves?" Revu asked her sister.
"Mmmmm… we can just play together for now. I want you to focus on me." Eru swayed slightly as she ran her hands up her body, over her flat chest and through her long hair. She gave a pretty good sensual display for being only nine years old.
"Oh, will you be alright Slevne? Seems like everyone has partnered up for sex." Revu questioned the older woman.
"Don't worry about me, darling. Unlike some people in this house, I am not in constant need of sex. Just go have fun with my little girl's new body." Slevne assured Revu. The pregnant woman was gently sliding the vibrating dildo in and out of her slick, puffy pussy. She gave a side glance at Gerno and Kolful who were still rutting hard over the table.
Eruda practically dragged Revu off to the back patio, passing by the love-nest in the process. That hedonistic room was decked out with all the comforts people might want while spending time engaged in various kinds of fornication. It occupied the central portion of the first floor with doors leading to it from all rooms that bordered it. The lighting was currently a moody orange, though it could be configured to a variety of colors and effects. There were a large assortment of places to lay oneself such as a hammock, a water-bed, a sex-swing and a plush fur rug. There were also a few pieces of rigging equipment and frames that saw occasional use. Pillows of all sizes and shapes were strewn about the room with some modicum of order. A large view-screen on one wall constantly played some soft porn and sensual music. Various stations situated around the room held lubricant, toys, wet wipes, stimulants, restraints, rope and sensation play tools.
On the large gray love seat, Nai had Mu bouncing steadily on her cock. The young cosmic child moaned as they took more and more of the futa's massive rod into their tight ass. Nai firmly guided the bouncing enby up and down with a strong grip, adding pressure to get their tiny ring to pop around the ridges of her cock. The pace was slow but persistent. Finally, after some thorough work, Mu was grinding down on Nai's full length. Their own starry night-sky penis was stiff and protruding outward like a galactic arm.
"Are you all loosened up sweetheart?" Nai grabbed Mu's shapely little ass with both hands. A light smack caused the child to gasp, both of their hands darting forward to rest on Nai's wide chest. The larger futa still had on her sports bra, the only bit of covering she had bothered to don at all this morning.
"I… I am." Mu shifted their hips again, grinding back and forth on the massive slab of meat wedged up their tight backdoor.
"Good. You've got your safe word but otherwise I'm not going to stop until I'm satisfied, understood?" Nai put a finger under Mu's chin and gazed seriously into their white eyes.
"Yes. Please show me what it means to be dominated." Through shaky breaths, the star child readied themself for what was to come.
Naibuna wrapped an arm around Mu's waist and stood. She effortlessly carried the child to a large bed and pulled them off of her cock. Throwing Mu onto their stomach, Nai wasted no time in mounting their small body. The much larger futa completely covered her partner. Mu's face was buried in the mattress, their hands moving out to grab at the sheets. Nai used one arm to lock around the child's neck in a choke hold, mostly to keep them in place but a bit of breath play would be fun as well. With her other hand, Nai guided the throbbing tip of her cock back between Mu's cheeks.
The first stroke was a full length pump of Nai's ten inches through the sphincter of the child. Mu's frantic squirming and muffled gasps didn't deter Nai in the slightest. She quickly ramped up the pace. Soon the ribbed cock was flying in and out of the tiny hole, pounding them with the same force and intensity Nai would use on an experienced professional whore. Her arm tightened around Mu's neck and she growled with unrestrained aggression. The small child could only whimper and squirm under the brutal assault, knowing full well this could last hours. It wasn't the first time Mu had been the target of such sexual fury, but it was the first time they were adamant about seeing it through to the end. The mental link to Naibuna was safely within reach in their mind but the cosmic child wanted to know what it was like to really get their guts mercilessly rearranged by a dominant force.
Upstairs, Ricca had instructed Ekizo how she wanted to feel his new tongue. The young boy was laying on his back in his own bed, deftly stroking his erection as he watched his aunt. The red-haired woman tapped the thin shoulder straps of her dress and the garment came undone, sliding to the floor in a pile of red fabric. Wearing only a red garter and thigh straps beneath, Ricca took a moment to flaunt her body to the boy before mounting his head. The matriarch sported a perfectly tight hourglass figure. She had an incredibly firm body, not from muscles but rather her flesh was like firm plastic. Her ass and tits were large but did not sag in the slightest, creating perfectly round orbs that hung in the air. Her holes were much more pliant as they needed to expand greatly for almost any sized phallus. The pink gems embedded down her spine sparkled with life as she spun around.
Eki had been with his aunt many times before, but not in several months. Yenzl was more dazzled by the woman's body, appreciating it as she showed off before moving to the bed. The young futa was getting hard now, a tent appearing in her borrowed shirt. She was just off to the side of the bed, watching as Ricca threw a leg over Eki's head and slipped down onto his mouth. He eagerly went to work on the juicy pussy in his face, even moving his hands up to grab at her birthing hips. The older woman didn't react at first, then her eyes went wide and her breathing became erratic.
"OHHHHH…. FUCK." Ricca shouted as her hips went wild, bucking and grinding all over Eki's face. His tongue was fully extended, digging deep into her canal like a snake. His muscles were more than strong enough to press hard into any sweet spot he found and swiftly flick at any nub of pleasure he discovered. The long organ writhed around inside Ricca, searching for the deepest spots it could reach. The woman shook with pleasure and dropped more of her weight down onto the boy's head. One of her hands snapped to her pussy, rubbing around her clit.
"And he's just getting used to it now. Imagine what he'll be able to do in a few years." Yenzl crawled her way onto the bed between Ekizo's legs. She demurely ran a single finger up his achingly hard erection, watching as the stiff pecker twitched and leaked a bead of precum. Her tongue dashed out to lick up the tasty treat. Deciding he'd gone too long without cumming already, Yenzl graciously took his penis into her mouth and began to suck on it. He came after just a few moments of work, flooding his mistress' mouth with a healthy load of spunk. Yenzl swallowed it down and kept sucking. Eki did not lose even a fraction of his hardness, still rock solid after an orgasm.
The twins had been quite excited leading up to their modifications. The amount of choices they had to work with were staggering, even though most all-encompassing and body-plan changing mods were still restricted to them. Naibuna and Slevne had spent some time helping the kids sort through the possibilities and select a few fun and interesting mods. Nai had discouraged them from going overboard as that might make the experience more hectic. Some mods required special maintenance or discharge of waste products. Sticking to fun, simple changes kept the twins first experience smooth, allowing them to fully test their own reactions. More complex changes could come after the twins had a bit more familiarity with the process.
Each of the twins had ultimately selected two mods and one minor alteration to try out. Eki had his tongue and another mod allowing him to remain erect practically indefinitely. His stamina was moderately enhanced by this mod but he would still tire and his level of arousal could fluctuate. Just because he was always hard didn't mean he was always horny. Though the young boy was very often horny anyway. His minor alteration was a general musculature enhancement, making him just a bit stronger in every aspect.
Out on the back patio, on the edge of the large pool, Revu was enjoying Eruda's new mods. The duo was laid out on a pool lounge chair, Revu on her back and Eru resting comfortably on top of her sister. The young girl had insisted upon getting one of her bikinis from the storage area before coming out to the pool. It was a slim royal blue garment that technically covered everything but left little to the imagination. Not that Revu needed to imagine what her sister looked like naked.
The teen futa had opened a designated slot in her romper shorts for her cock to pop through. The rod was not quite as big as Naibuna's but it had some heft and girth. Eruda slid her bottoms out of the way and enjoyed feeling the dick fill up her pussy as she slid down into Revu's lap. Eru leaned down, stretched her neck and kissed her sister intimately. Revu accepted the kiss gratefully, running her hands up the young girls lithe back. Both ladies had long, straight black hair; one of Nai's more 'natural' genetic traits that was often passed down to her children. The long cascade of their hair mixed together into a river of ebony sheen.
"Okay, I'm gonna start." Eruda sat up, flicked her hair back over her shoulder and flexed her core.
"Alright, I'm curious as to-" Revu didn't finish the sentence, instead letting out a loud surprised moan. Her eyes went wide and almost rolled back in her head. Her hands darted out to grab Eru's waist, gripping onto her like a lifeline.
Eruda giggled innocently. "That's how mom reacted too."
The little vixen was barely moving up or down, instead relying on her internal muscles to do the work of pleasuring the phallus inside her pussy. Eru's vagina had been modded to be both more elastic and have increased muscular control. Her asshole had undergone nearly identical treatment. She could now directly command every individual muscle in those orifices to act exactly as she intended. Their strength had also been fairly enhanced. The result was less like a traditional sexual orifice and more like a powerful massage tool that could stimulate every inch of a phallus at once.
Revu mindlessly bucked her hips up, sending her sister rocking forward and giggling more. The futa had never experienced something like this before, it was like her dick was being caressed and stimulated by a dozen unreasonably powerful, well coordinated tongues. Every inch of her cock was being rubbed and squeezed in waves of undulating pleasure. Even just a few moments of the treatment had rocked her world. "Czist… ffffucking anterior! Stop, stop for a moment please!"
Eruda panicked. She released her internal grip on Revu's cock and attempted to get off of her sister. Revu, however, kept a solid grip on the girl's hips. "No, no... you're fine. Just… aaah… just a moment."
Eruda pulled back and waited patiently as Revu caught her breath and regained her mental fortitude. The young girl had only every had two people ask her to stop during sex, both times had been at school with children younger than her. She was a bit shaken that her older sister had gone to such an extreme. "I'm sorry."
"Oh sweetie, it's okay! That was just too intense for me. I suppose I'm just... not as accustomed to that level of stimulation as mom or Gerno is. Fuck, it was incredible though. Starting out with that move might be too much, it's a good finisher but not for warming up. Can you tone it down a bit? Maybe one or two levels lower?" Revu was still breathing hard but had mostly recovered. Her cock twitched inside Eru.
"Are you sure you're okay?" Eruda reached a timid hand out to place it on her sister's chest.
"Perfectly fine. And I want more. Just… less intense." Revu comforted her little sister, gazing lovingly into her eyes.
Eru nodded. She focused on starting up some internal muscles, letting most remain silent. Revu moaned peacefully and moved her hands to Eru's sides, gently pulling the girl down into an embrace. Eruda melted into it, glad her sister wasn't hurt or scared in any way. Revu whispered into her little lover's ear; "Just keep going like that, it feels great. I'm going to thrust up a bit…. Fuuuuck you feel so good. I love you."
The two sisters continued their relaxed, languid sexual encounter under the bright sun as the wind lapped at the pool water and rustled the distant trees. A long stretch of time passed as as the two bathed each other in sweet pleasure. Revu did ask Eruda to increase her intensity at one point, but not to full power. This quickly caused the futa to climax deep inside her sister, filling the little minx to the brim with a thick load of spunk. The two laid still on the lounge chair, basking in the warm weather and each others bodies. Sticky, white seed leaked from Eru's hole onto Revu's thigh. Revu quickly fired off a message to Naibuna and Slevne describing what had happened and that it wasn't a huge concern. Eru just needed to get a better grasp of what her new mods were capable of.
"Alright, I'm getting too hot. Let's go in and see what everyone is up to." Revu prompted her sister. Together they cleaned up a bit at the pool station, wiping cum from their crotches and rearranging their clothing.
Gerno was in the main living room, watching a documentary about the history and logistics of planetary mining. He was alone and fully clothed, a rarity when the household had so many occupants. He cheerfully greeted his sisters as they entered the house. "Welcome in. You two looked lovely out there."
"Thanks!" Eruda launched herself onto the couch beside her big brother.
"You were right. Eru's holes are absolutely divine. Awe inspiringly powerful." Revu also took a seat on the cool, soft couch; letting her body radiate off some of the heat from being in the sun. She queued up the kitchen automations through the system and ordered a glass of nucloq juice then opened up the order to her siblings if they wanted anything.
"Soda! Yes!" Eruda suddenly cheered.
Gerno and Revu eyed each other knowingly but remained silent about their sister's consumption of the sugary beverage. All three siblings relaxed on the sofa and chit-chatted over the documentary. Naibuna had sired each of them at different times with different women in different parts of the world, yet they all considered each other to be proper 'siblings'. The word was most often used to refer to someone with whom you shared a single parent. Having both parents in common meant you were a 'full sibling' with that person. However the distinction rarely if ever mattered.
"Did you see her tattoo?" Gerno asked Revu. Eruda quickly hopped up and showed off her tramp stamp, situated on her lower back just above her bikini bottoms. It was the numeral '2' surrounded by stylized vines and flowers. The number could change and automatically updated to reflect the number of sexual partners Eruda had been with during the current day. It was her minor alteration, with just enough smart ink to count up to '99'. If the little girl had one hundred or more sexual partners in a single day then that feat would just have to be commemorated in some other way.
Eruda happily consumed her soda when it arrived via automation server and then quickly became bored with her siblings discussion of terraforming logistics. Bidding them a hasty farewell, the little slut scampered off to see who else was doing something more fun. She peaked into the love-nest, seeing her mother rutting hard into Mu. Nai had gotten a collar and leash around the starchild's neck and was using it to pull them into position. The bed around the two of them was coated in a layer of cum, a mixture from both of their cocks. Mu's spend was much more discernible as it glowed a bright white in the dim room. Eru watched as the small enby came again, spraying more bio-luminescent cum onto the sheets as Nai plowed their guts with unrestrained force. Deciding that situation was a bit more intense than she wanted to be involved in right now, Eru wandered back through the house to the manual kitchen. There she found Ricca preparing some food.
"Hello little one. Care to help me cook?" Ricca welcomed her in as she was chopping some vegetables. The red-haired woman had donned just an apron in order to cook. Her only other garment being the red garter belt and thigh straps that framed her ass like a piece of art.
"No thanks. How was Eki's new tongue?" Eruda hopped onto a nearby stool at the side counter and watched the older woman work.
"Sublime. Maybe the best I've ever had. I squirted like a faulty sprinkler all over his bed. Have you not tried out your brother's mods yet?" Ricca questioned the young girl.
"Nope. Our moms said that we should be comfortable with our own bodies before getting together."
"Mmm. A wise bit of advice." Ricca chopped more ingredients and started up a frying pan. She noticed Eruda eyeing up her ass. "You're more than welcome to watch hon but I don't play when I'm cooking."
"Okay." Eruda crossed her arms and laid her head on the counter, swinging her feet idly.
"I heard about your vaginal and anal mod, it sounds like quite the powerhouse. What else did you choose to modify yourself with?"
"It isn't sexual. It's a deeper system sink… synk… syc… synch-ro-ni-za-tion." Eruda had to carefully pronounce the big word. She intuitively knew how to pronounce it but her small mouth had trouble actually making all the sounds.
"Oh. Interesting. I assumed Naibuna would steer you away from more digital integrations." Ricca commented.
"Yeah. I just wanted to know what it felt like to be everywhere."
"How deep have you gone?"
"Just a little below the surface. It was…" Eruda gestured with her hands in a certain manner.
"Yes. It certainly is."
Upstairs Yenzl had been 'coerced' by the cat into giving her more sex. Yenzl's father had several animal-people in his harem so the futa was aware of the social customs around them and when it was acceptable to give them what they wanted. This particular catgirl was remarkably spoiled. Slevne had assured the young futa that it was okay to give in to Kolful's persistent advances, that's just what most everyone did anyway. Yenzl was fucking the catgirl in missionary on the guestroom bed. Her over sized shirt was getting in the way so the futa grabbed the hem of it and lifted it up and off her body.
As she pumped her slender cock into the cunt of the orange haired catgirl, Yenzl let her mind wander to the idea of expanding her harem. Ekizo had been a lovely first concubine and Yenzl had enjoyed getting to know his family. It was never a secret that Yenzl would eventually take other concubines, that was clearly conveyed at the start of the relationship. But the young futa hadn't felt a need to find anyone else in the preceding months, leading Eki to become quite comfortable in his position as her sole concubine. Finding a more dominant lover would be an ideal next step, but Yenzl was unsure of who she would want in that position. Eki was also free to find other partners, she would never restrict him from such a thing. How would that affect their time together?
"Mrow?" Kolful tilted her head and gave a confused vocalization. Yenzl had slowed down her pace considerably and wore a blank expression.
"I'm sorry. I was lost in thought." The young futa pumped her hips faster and gave the catgirl more attention, kissing her breasts and gripping her sides.
Midday came about quickly with all of the sexual fervor floating around the house. Naibuna and Mu emerged from their den of depravity completely covered in sweat and cum. The larger futanari cradled the small starchild in her arms, lavishing them in praise as they made their way to the first floor bathroom. The process of getting them clean and revitalized took a significant amount of time, long enough for Ricca to send out the house-wide message that lunch would be served soon. Nai replied with an affirmation but sank even deeper into the warm bath, still holding her little lover close.
The meal was a distinctive one. Fried Gudrnil flanks marinated in a rich blend of spices from the Tho-hk galaxy and covered in sauteed vegetables. A large mixed salad and freshly made whole-grain chips accompanied the main dish. All ingredients synthesized by the house printer but lovingly hand crafted by Ricca. Everyone gathered around the table once again to partake of the meal.
"Nothing like what you'll get out of those cooking automations. This is real craftsmanship." The red-haired woman smirked proudly as she watched the assemblage of friends and family partake of her food.
"It's good. Real good. Thanks aunt Ricca." Gerno said after finishing a piece of meat.
"Thanks mom!" Revu chimed. The rest of the group followed suit. Many of them had rarely ever eaten a human cooked meal. Eru and Eki especially were happy to try something new, though Ricca had deliberately toned down the spices for the youngsters. Mu was well acquainted with their mother's cooking and liked things with incredibly rich flavors.
Upon finishing the meal, Ricca cornered Naibuna and pushed the futa up against a door frame.
"Love. It has been far too long since you've done your marital duty." Ricca poked a finger at Nai's chest.
"Oh, and what ever would that be?" Nai joked innocently. She slid her hands over her wife's supple hips, pulling at her garter straps.
"Ugh. You are a dense oaf sometimes. Breed me. Now." Ricca kissed her wife then, pushing the larger futa back into the living room.
"Well. I'd like to see this." Slevne pushed herself up and walked after them. Revu, Mu, Yenzl and Eruda followed soon after. Gerno, Kolful and Ekizo were less enthused but figured they might as well tag along if everyone was going to be in the living room.
Ricca had already pushed her wife onto a couch and mounted her thick cock as everyone filed in and found a good position to watch from. The red-haired woman was lightly grinding down onto Nai's lap while whispering dirty words in her ear. Eki and Eru giggled back and forth as they jumped onto a secondary couch. Yenzl joined them, now wearing one of her own sheer yellow dresses. Revu and Gerno occupied another couch, facing opposite most of the action. Both were totally nude, allowing their cocks to visibly start to stiffen at the sight of Ricca riding Nai.
"Excuse me. I have never been with a pregnant woman before. May I fuck you?" Mu earnestly approached Slevne as the woman reclined sideways on a large love seat.
"Why of course, sweet thing~" Slevne spread her legs and removed the vibrating dildo from her pussy, spreading her gushing wet lips to invite Mu inside. The starchild slid one leg onto the love seat and positioned their cock at her entrance. A short thrust hilted their entire length inside the woman. Mu began to pump their hips in earnest while running their hands over Sleven's big, round belly.
Gerno and Revu were both stroking themselves passively as the breeding sex across the room was heating up. Gerno didn't particularly enjoy jacking off as it took more work for him to stimulate both of his phalluses. He much preferred to have two mouths working on his erections. To remedy this, he shot a poke through the system at all three of the younger children on the other couch. Ekizo, Yenzl and Eruda all perked up and looked over to him. Beckoning the kids over with a grin, Gerno soon had Yenzl and Eruda licking and sucking on his cocks. The two girls were more than happy to service him together, their hands resting over each other's waists. Revu claimed Eki for herself, getting to feel the boy's new tongue for the first time.
"Wow. Ah, yeah that's nice." Revu got a grip on her brother's hair and angled her hips so he could swallow more of her cock. Once Eki's nose touched her crotch, his tongue snaked out of his mouth and moved downward to lick at her balls.
The room was filled with the sounds of various carnal unions. Squelching, slurping, slapping, kissing and panting came in all different patterns and intensities. The focus of the room was still on Naibuna and Ricca as they copulated loudly and passionately. Ricca's thick ass was pumping up and down on Nai's girthy cock, milking it with powerful strokes. The two lovers kissed in a sloppy exchange, tongues constantly slipping over each other. Nai gripped her wife's hips tightly as the tip of her dick kissed the woman's womb over and over.
"Ngghh I forgot how much I love filling up this fertile little fuck hole." Nai landed a forceful slap on Ricca's ass, the resounding sound of which filled up the whole room.
"MMMM-! Fuck~ Give it to me. Give it to me right now. Knock me up again love, I want another baby!" Ricca moaned out as her hips went into overdrive. She rode her wife like a feral beast. Pumping hard and fast in a desperate attempt to get Nai to cum inside her.
Giving in to her wife's desires, Nai let herself be taken over the edge. She gripped Ricca's ass hard and pushed her down. Sending the entire ten inches of her breeding tool all the way into the redhead's greedy cunt. Nai growled and bit the side of Ricca's neck as she began to cum. A flood of fertile baby batter filled up Ricca's deepest recesses. The woman shook her hips in an attempt to coax even more splooge from her wife's fat balls. Kolful, who had been relaxing nearby the entire time, perked up at the new development. She slinked closer and watched as Nai's seed began to leak from their union. The catgirl tentatively licked at the mess, trying to capture all of her master's fertile spunk that escaped.
Revu watched closely as her parents made her younger full sibling. The teen already had more than a dozen younger siblings and had watched (sometimes even participated in) the conception of many of them. But a full sibling would be nice to really help raise. Revu recalled her older full sister, Onoco, who had moved to a colony world a few years ago to be a freighter pilot. She'd been an instrumental figure in Revu's younger years, helping her understand her sexuality and passions.
Pulled out of her thoughts, Revu moaned as Eki worked her shaft and head like a pro. His tongue had wrapped around her balls and was almost holding them hostage. Revu had just about reached her peak and was humping up into her brother's throat with firm pumps. "I'm gonna- oohhhhh fuck- I'm gonna cum!"
Eki happily gulped down his sister's hot load. He continued to lather her balls in spit and massage her shaft with his tongue as the orgasm continued. Once he'd swallowed a healthy amount of her spunk, Revu released her grip on his head and the boy pulled back. He sucked on her tip one last time to make sure he got everything, then turned to look at the other group on the couch.
Yenzl had gotten her wish as she was riding Gerno in reverse cow-girl, both of his cocks slipping into her small holes. They were visibly stretched around his shafts. Yen had her eyes tightly closed, focusing on bouncing slowly and steadily. That left Eruda without an immediate partner, kneeling at the foot of the couch and fondling herself to the sexual intercourse happening right in front of her. Eki reached over and poked her shoulder.
"Hey." The young girl squeaked out as she fingered herself.
"Hey." Eki replied, stiff cock in hand.
Mom, Slevne. The twins want to have sex with each other. Revu made a mental call, including the twins and their parents.
I think they're ready. Just keep an eye on then would you dear? Slevne replied. She was still taking Mu's cock even after the starchild had blown a load in her pregnant pussy.
Naibuna gave the equivalent of a permissive mental grunt. She was cuddled up with Ricca on the large couch, the two were all but lost in each other's embrace after their frantic copulation.
Eki immediately moved to join with Eru. The two little ones fell back onto the floor and kissed. They were starved of each other's bodies, having gone more than a full day without engaging in sex together. And the added excitement of their new mods made the it even better. Eki humped his sister's crotch, feeling her wetness lube up his erection nicely. Eru moaned sweetly into his mouth, hands running up and down his back.
The twins pulled back a little, each panting lightly and gazing into the other's eyes. They didn't need words or even a mental link to communicate. Their bond offered a special knowledge of how the other thought and what they wanted. Eki shifted his hips around to line himself up with Eru's welcoming hole. He kissed her again, this time sending his tongue further into her mouth, exploring all of the new places he could reach. It wrapped around Eru's own tongue like a possessive tendril and pulled their mouths even closer together.
Eru squirmed at the new sensations but held her own. She wrapped her legs around her brother's hips and pulled him into her. Having had the experience with Revu this morning, she knew not to overwhelm him at first. Instead she had her inner walls massage and squeeze his stiff rod in gentle waves. Eki groaned as he bottomed out inside his sister. Her once very familiar pussy had become something else, but he was excited to get to know it again. His cock flared with pleasure as Eru worked her magic. His hips rocked forward, trying to press even more of his length inside of her.
Revu watched from the couch, her own erection slowly pulsing back to life. The twins were always so adorable together. Even more so now. Watching them fuck was like seeing two stars merge after dancing around each other for eons. A climactic crescendo came when Eruda, presumably, upped her intensity. Eki trembled as he had his boy-cock milked for all it was worth. Revu could tell he was cumming by the proud hum Eruda gave as she was filled with his seed.
Neither of the two were done after just that. They continued to grind and rut for quite a while, even long after most everyone had left the living room. Revu kept watch over them, idly checking her messages as they fucked themselves into an incestuous stupor. She then extracted her payment for her time, turning both of the twins onto their stomachs and eagerly spreading their cute butts to eat their tasty little assholes. She even recorded the act, saving it for her collection.
It was late as the trio of city dwellers began to make their preparations to depart. Clothing was recovered from various places all over the house. Ricca's dress was retrieved from Ekizo's room, Revu's romper was found underneath the dining table, and Mu's shorts were fished out of a pile of pillows in the love nest. The three redressed languidly in the front antechamber. Nai watched her guests cover their bodies with a speck of arousal. The day had been long and sex-filled but her cock was still ready for a bit more.
"Love you mom." Revu stood on her toes to kiss her mother's cheek.
"Thank you for the incredible sex. My ass will remember the shape of your cock for days." Mu spoke up with their layered harmony of voices.
"And thank you for the rough breeding, love." Ricca also kissed Nai, much more passionately.
"Mmm, you all are more than welcome. Feel free to stop by anytime." Nai cordially ushered her guests to the front door and watched as they walked down the driveway, asses swaying gently. Nai had offered them the transport shuttle but they preferred to walk. City folk were much more comfortable with walking wherever they needed to go.
Turning her attention back inside, Nai did a quick scan of the house just to ensure everyone was comfortable and that the nightly automated procedures were running smoothly. She found that Gerno, Eruda and Ekizo were cuddled up in the love-nest, probably enjoying some sibling bonding. Yenzl was surprisingly in Slevne's room with the blonde woman. Nai curiously tapped into the camera in that room and saw the young futa sodomizing her pregnant companion in doggy style. Kolful was fully relaxing in the sauna and seemed to not want to be disturbed.
Naibuna quickly decided on joining Slevne and Yenzl. She hadn't gotten to try out the young futa's pussy yet, which seemed like a careless oversight. Yenzl was on an extended stay with the family after all, might as well make the most of it. Setting that as her goal for the night, the amazonian futa made her way up the stairs toward even more sensual pleasures.
