Chapter Text

It was an early morning, the sun had barely come up and the woman of the house had only just barely arisen with a deep yawn. Eyes twitching open, arms slowly outstretching to the point of aching, the lady was clearly exhausted, to the point where she was nude and she hadn’t even noticed or cared, she had convinced the only other resident to stay nude since it was only them living their. Her muscular tan skin and the abs that came with that as well as her private bits out in the open. The last thing Nani remembered was crashing home after a night of aggressive breeding. Having vague memories and words in her mind of her client that night having asked her to pump a baby into her maybe? She couldn’t remember very well but it didn’t matter since it clearly must have been a good night if she felt this drained from it. But despite how well she might have been milked before sleep, her sheer sexual energy was far higher than any normal living thing let alone any male. She knew it wouldn’t be enough to last and thus she began her morning routine of taking care of her morning wood, but then Nani caught something in the corner of her eye as she was just beginning to pleasure herself, something quite special to her Nani had noticed. The door was open the whole time, she must have been so tired she hadn’t noticed that it was never shut but this was a blessing really. A small little girl had just walked past the door completely naked and unnoticing of what was happening to Nani, the last thing Nani saw of her was her butt walking by and her thighs. The little girl was her sister Lilo and her brief exposure sent Nani into a lustful overdrive like state. Lilo was a chubby girl but Nani liked that about her, she was thick in all the right places and then some. Her thighs and hips were always plump and that pudgy tummy was always adorable to her but that was nothing compared to by far her best asset being her big fat butt. She always had a nice ass. She even distinctly remembers her parents jokingly bringing up how big it was even when she was a baby, even then Nani couldn’t stop thinking about it, that alone made her aroused. Nani at that time would sometimes watch her in her crib and rub one out in front of her and coat her body in sperm before she even learned to speak, not that she would remember of course, her figure was quite similar to how it appears now, cute chubby baby belly, plump hips and thighs and the way her ass stuck out in her baby clothes always drove her rabid. It was like she was in a set of ass huggers for infants. It always sent her into a lustful daze just staring, Nani was already becoming very sexually active at age of 11 no doubt thanks to her being a unique case physically, she was a one in a billion birth after all. Finding her fathers porn or creeping on her mother naked and watching the two make love gave her plenty to look over and fantasize about allowing her degeneracy to grow and the parents were none the wiser. All this leading up to Lilo's birth which not only meant Nani would have a sister but also someone she could groom into being like her, she was desperate to have someone relate to her. At age 12 Nani would sometimes rub her cock against her baby sister's soft smooth belly and sandwich herself between Lilo's thighs, devouring her vagina or anus like a rabid animal. Her favorite was when she would place her cock in between her supple butt cheeks and just keep thrusting, the feeling was unlike anything else she had experienced her hands simply could not compare. And so night after night Nani would satisfy herself with her sister, firing long thick warm ropes of semen over every inch of her body, her face, butt, feet, back, the white cum contrasting nicely against her brown skin. But Nani knew that as her sister grew older the risk grew as well and that she would need to think of a way to maintain this relationship to sate her ever looming nymphomania and Lilo’s developing body making her even more attractive then she already was to her wasn’t helping. Sure she had the ladies who paid for her services as a potential outlet but it wasn’t the same and plus she’d rarely ever get to use her weapon between her legs for release since a decent chunk of her employers were men relieving themselves into her instead. She wanted Lilo, needed her, her body had been antagonizing her for years to where it almost was if it was asking for it. The way Lilo would where her red shirt that always was too big for her yet her large butt still managed to visibly protrude outwards displaying one of her best attributes accidentally would always give Nani a stiffy, to the point where she would have to excuse herself just to choke her feminine chicken in private. She might have convinced her to go nude but that would only be the beginning as there was still much more work that needed to be done to secure her as the perfect mate. All of a sudden a plan had come to her and she immediately stopped stroking her rather larger cock instead of cumming then and there, deciding to gather herself off her bed.

Nani sat herself down on the family couch by the dining room, erect cock in hand, softly stroking up and down, peeling the foreskin for a second before pumping upwards and recovering her tip. Smooth tan skin wrapping around her cock head before slowly stroking her cock downwards all the way to the base, large pulsating veins made themselves apparent on the base of her 8.5 inch shaft all stemming from her self satisfying. Lilo was in the kitchen doing whatever, she wasn’t sure but most likely making a mess that she would have to clean up later but the what and why didn’t matter now because all that was on her mind was the show on display, she could see Lilos gracious naked figure from across the room, any mess she’d have made would have to come in later she was too pent up too care. 

The way her plump ass cheeks wobbled and jiggled about whenever she was moving about, her fat hips and thighs gyrating as she moved her legs and her soft smooth chubby tummy were simply perfect especially for her age. For a 5 year old her body looked simply divine to Nani and just looking at her drove all kinds of degenerate thoughts into her mind, vivid thoughts and images popped in her mind of defiling and violating Lilo in all kinds of different ways. Putting her little sister into a violent and aggressive piledriver or mating press while staring directly at her and going in for a kiss. “ How am I still so hard? Especially after last night?” she thought to herself “ I really gotta take care of this before work, damn you Lilo! Always making me heat up without fail every single time! Even when I shouldn't be able to have s-so much energy!” she started becoming slightly frustrated at her own thought bubbles; she could barely think of the words in her head properly all the while she continued to masturbate. “Maybe telling her she was free to go nude as long as it was only us in the house was a bad idea?” her hands came to a standstill for a second “ Yeah but she loves being naked around the house! I've never seen her so happy in so long and I can hardly resist that smile when she's happy it makes it all worth it….. Ahhh but what if she starts getting bad habits? What if I get a call from the school staff about Lilo going naked in class?” 

Just then she heard a metallic BAM noise of what was presumably Lilo accidentally dropping some kind of kitchenware. Nani sighed in disappointment at herself “ Oh Lilo…. It might be a bit too late for bad habits now” feeling reasonably responsabile at her failure to properly look after her sister before she could potentially harm herself. “ Bad habits…perhaps I should come up with some kind of punishment for that to teach her some lessons.” and then and there the idea of sexual punishments had struck her mind, images of  Lilo's tight butt milking her cock as punishment for any of her common acts of childish mischief. Pondering on what kind of face would be on display while she gets filled with blood relative futa cock, would it be a contorted face of pain? One of lust? So many cute faces her sexy sister could have, it was a perfect way to get closer to her sister sexually. Such lustful thoughts were really getting her in heat to the point where she started to speed up masturbation going from long strokes on her shaft to swiftful ones. All this lust aimed at the little girl across the room who didn’t even notice what she was doing, this almost covert act made the situation more attractive to Nani in an odd way. Nani had noticed Lilo quickly walking past the entrance of the kitchen wearing an comically oversized apron, this short lived image sent Nanis furious masturbation into an aggressive pumping of her cock now using both hands on her meat “ Darn on second thought maybe allowing her to be naked ain’t so bad...aww hell ill worry about it later this feels too good to pass on now! God damnit Lilo” her eyes were scrunched closed and her hands still seizing her cock, her mind was in a daze blinded by lustful thoughts without a care for what was going on in the world around her. All she could see were images of vile and depraved acts being performed on her beloved little sister. Lilo dressed half naked in black leather, covering barely any skin, thighs still clearly naked for the most part, black gloves on her hands and black leggings as well,  bending over and showing off her body “ hnnngh Lilo….” , Nani decided to spice up her fantasy and imagined a lollipop in her mouth and nipples covered by a tiny string right above them, her tummy out for everyone to see “ Lilo….lilo I…. I want you so badly” to top off her ideal sibling outfit she had a black g string on the crack of her juicy butt. Going from deep in her buttocks swallowing it, into two strings on her shoulders, it was perfection in her mind. Her sister was a fine young lady but this fantasy idealized version of her was simply something else entirely, the peak of her sexual appeal “ shoot why can’t it be simpler to get a nice cute outfit like that for a girl… let alone having to get one specifically her size. Fishnets wouldn’t be bad either damn especially with legs like hers! ”. 

She became frustrated at the seemingly  impossibility and improbability of her fantasies coming to life and so she decided to take out that frustration onto her man-like woman hood. She was practically thrusting up and down and having sex with her own hands. Eyes tight shut images rushing in her head like a fast paced slideshow all visualizations of lilos body helping to amplify the already massive amounts of pleasure she was going through, as if jolts of lightning were surging through her body and her man/woman hood, the pleasure felt as if her entire being was filling with ecstasy her brain was running wild with all kinds of feel good chemicals being pumped and fired off into her. Masturbation might get old and not be close to the real thing at times but when she saw a figure as divine as Lilo’s it might as well be the real thing when she starts stroking herself with how good it feels at those moments, even smashing uglies with some of her regular clients doesn’t reach this same level of high at times. All that masturbation and imagery were running their course, building to what felt like an almost unimaginable climax to her; it was much better than anything she tried doing last night to her client. Her already fast paced pumping elevating and quickening in rate, both hands from tip to bottom of the shaft right above her testicles, her head exposed and radiating a musky aura throughout the living room. She had already known that the couch would have to be cleaned at some point to remove the stench of her heated up precipitating body, penis, and her musk but once again she was far too concerned with her current pleasure to care. 

Her entire body including her aggressively beating heart were ablaze. She felt as if a volcano was rising from her thighs to her testicles, to her base, she was ready to finish soon. The fire inside her was rising inch by inch “HHNNNGH …..HOOMPH HOOMPH” and it was taking its toll on her, overwhelming her to the point of grunting like an animal and taking in deep breaths. The flame inside her had reached her tip, she was ready. She pulled her foreskin upwards covering her and began rapidly peeling and unpeeling. stroking her head in a quick frustrating manner up and down on the head but it was already done. Her unique reproductive organ was finished and right then her body was completely overwhelmed, jolting and spasming her body. She threw her head back, her face aiming upwards and MOANED   IN A DEEP, SOFT, LONG, & LOUD expression. “ HHHHNNGGHG DAMNIT LILO!” She could feel the fluids in her testicles being pumped up into her shaft and being unleashed through her tip. She had no idea where she was aiming her eyes were still shut, if she wasn’t overtaken by lust she might have been disgusted with herself making a mess but deep down she was in a degenerate enough mood to want to paint her parents house with her own semen, it felt wrong and gross yet that only made it feel a bit better. She aimed her cock towards her chest and felt her organ shift and churn, semen running through her body and leaving her in the form of thick, long, warm strands of pure white sperm landing on her abs and even her breasts. She squirmed somewhat at the feeling of long hot liquids touching and coating her body. Her sexual labor was really starting to show in the form of her impressively powerful orgasm, it was so strong she managed to get some sperm on her face around her nose and eye. 

“ breath-in , breath-out, breath-in……. SIIGGGGH ”  her panting was forming into a deep breathing from the expending of energy she had just went through. In more ways than one she could feel that experience take a lot out of her, her body was calming and relaxing itself. Relaxing her hands on her head in exhaustion, her sexual parts shrinking, churning, and aching at high amounts of expended semen and lustful energy. “ Phew…that was something else…even for me ... .wow” she was in true awe of herself and impressed at what she managed to do just having fun with herself and the somewhat indirect help of her sister. “ Ok lilo….. NOW lets see how you're trying to destroy the house today” she thought to herself with a smirk….. But then she opened her eyes and immediately was struck with an immense heart stopping shock, the kind that could cause a heart attack to a weaker being as right then and there as her vision slowly came too from a blurry mess to a sharp clear image of a tan figure she saw the very girl her self afflicted affection was aimed at appear in front of her, a naked body appeared before her with a look of confusion and fascination on her face, her pudgy belly and face covered in long ropes of sticky and thick semen, her left eye even had been closed from being covered in a line of sperm. She was staring right at her with one eye open as Nani sat there with her eyes widened in complete silence and shock, mouth agape yet no words coming from it. Lilo’s blank expression shifted from a look of interest to a small grin as her lips moved upwards. Time was frozen for a second as the sisters stared each other down, thoughts racing in Nani’s head, some of fear , worry, and horror and others of slight excitement. The one thing breaking the extensive silence between them was a small chuckle from Lilo           

Haha! You said a naughty word!

“OH DAMNIT LILO!” Nani had yelled, “oh crap OH CRAP how long have you been standing there watching me! Shoot! SHOOT SHOOT! I GOT ALL T-THIS THIS THIS ….MESS ON YOU! I'M SORRY". She was lying, and she felt gross about it but she thought it was the right thing to do for her young childish sister. She always loved painting her sister with the sexual excretions of her penis and she found her messy predicament quite attractive really. But she knew her position as a protective and upstanding guardian for her sister came first before her lustful attraction to her, or so she told herself.  “Hahaha! Oooooo you got such a potty mouth today Nani!” Lilo was simply smirking and continued laughing at her sister's verbal profanities.

Nani continued beating on her already well corrupted and enlarged futanari womanhood. Lilo already covered in her baby batter anyway so the situation was already worse regardless so she might as well get some enjoyment out of it by taking a nice long look at the sexy view of her chubby sister beginning to slather her body in her sperm making a mess of every plump inch of her small and adorable body, she was still such an innocent and cute troublemaker after all.

“You made a mess in the kitchen didn’t you! I heard you making a goddamn ruckus in that ro-“

“Hey now don’t change the subject, miss!”  Lilo interjected immediately before Nani could finish her statement calling out her wild child brat  sister on her behavior. “ You’ve been hanging around in your room all day lately playing with your thing or going out working to where I never even see you! I don’t even know what it is your doing with your boy … girl part thing or why you like doing it so much but meanwhile!” She started talking in her smug tone of voice. She knew nani found it irritating as she rolled her eyes but that was half the fun in talking that way for her. “I’ve been experimenting in the kitchen making fine cuisine to feed myself while you’ve been doing …. Whatever it is that’s  apparently so fun for you that it’s better than playing with your sister! Playing with your thing can be that fun! I mean i don’t go to bathroom to use my petunia all the time cause I like it”

Nani let her hands go as her erection was pulsating now, just letting it throb. Lilo was still so naive on the properties of lust and sexual activity but in a way it was kinda adorable. 

*sigh* “I see you’ve noticed huh….” Nani was rubbing against her eyes with a tired sigh and a hint of shame 

“Well DUH! I dunno what’s gotten into but you're not quiet about it! *PFFFTTT*” Lilo ended her little rant by sticking her tongue out at her sister. 

“I’m….. sorry lilo. I’ve just been really stressed out at work” she wasn’t that surprised that lilo took notice of her constant self pleasure escapades. She knew she wasn’t exactly super subtle about it but she didn’t mind at this revelation, deep down she wanted lilo to take notice. The quicker she finds out certain aspects about being an adult the better she thinks as she would have to grow up quickly now that it’s just them…. Or maybe that’s just a way to cope over the fact that she gets an erection over her underage sister's particularly plump rear and chubby figure.

“Excuses excuses that’s what I think! *Hmmph*” she scoffed at her big sister and closed her eyes and turned away slightly. “What’s so fun about it anyway?” Lilo opened her right eye slightly and looked directly at Nani’s veiny cock. She could feel the musky aura pierce her face by now as it infects the room. “You stink up the whole house with this thing too! I dunno how you can’t smell but I can get a whiff of this all the time just so much as making a step next to your room!”

She made a good point, she was so used to using her cock that she must have gotten used to the smell to where she would no longer notice it. That and the combination of maybe never closing the door all the way made her sister taking notice at her nonstop pumping all the more obvious. 

“*sigh* Yes, it’s fun. You don’t understand now but it’s a way to have fun on your own for adults…. Alright. It  just makes me feel good…. You’ll understand when you're older. Especially when after a stressful day” 

“Why is that the answer to all the good questions I wanna know the answer to! The teachers say when you're older, the adults say when you're older, and now you're saying when I’m older! Now I’m disappointed in you!”

Normally nani would groan and find her sister's naive curiosity to be exhausting and obnoxious but she noticed her cock throb a bit as she was talking. Was she finding her sister cute when upset? She wasn’t the only one who noticed 

“Why is it moving around on its own and stuff too! It’s weird! Is it alive too! Do boys have to deal with this too! Do you have to feed it or something!” Lilo spoke with a combination of girly disgust and childish curiosity. 

“No just …. Erm, think of it as like a tail for a dog ya know. We can just move it around when it’s hard.” Nani started throbbing her cock without touching it, it started moving up and down her crotch as a demonstration. Lilo stared at it in awe and wonder which helped make nani maintain her lust and erection having her own sister stare at her cock. Why didn’t she give a demonstration to her beloved sister sooner? 

 “So this is what makes you feel relaxed right? It looks so hard and stiff now when it was just all droopy ago! Kinda funny looking now” Lilo now stared down directly at her crotch, Nani’s cock head aimed straight at her. “Yes…. 

“Why’s it all hard now? It seems so annoying to handle. Ya know I'm glad I’m a girl really because if I had to deal with this all day especially at scho ol id ~.” Lilo’s words were starting to become a blur, Nani was only half paying attention to her sister babble on and on non stop as she occasionally would from her naturally never ending supply of “kid energy” as Nani referred to it as. *It's because of you and your sexy body god damnit!!* Nani was getting frustrated as she thought to herself or at least tried to as Lilo seemingly was still running her mouth but Nani had way too much on her mind to tell if she was just going crazy from sheer pent up lust and over stimulation from Lilo and the pulsating raging hard on caused by Lilos body in front of her. The world was starting to feel like it was in slow motion and her head was getting fuzzy *fuck I love you lilo youre my precious sister and you always will be but my god this is going to be a serious pain*.~ “Well you see lilo…..” Nani started brandishing her elongated penis in front of Lilo, a hand wrapped around right above the base of her impressive length. Just the touch alone was enough to give a small jolt of pleasure. She was going to try and explain but then her mind went blank for just a second. 

Her thoughts were empty and devoid of any possible regrets or repercussions for any actions she might perform, she looked directly at her sister at that moment and saw many things, a potential breeding queen who could bear many young, her beloved sister someone she would go to hell and back for, but also she saw a goddess. Having a perfect combination of the most adorable and yet also sexy traits imaginable to a perfect blend. Just blankly staring at her thickness This gave her just one feeling and one feeling alone, a want , a need .

DESIRE

Fuck…..Lilo…..I want you right now….I need you BADLY right now.

“ N-nani?”

  Some inner animalistic instincts must have taken over her mind as at that moment hearing her sister address her she suddenly noticed that Lilo was pinned on The floor beneath her and a pulsating veiny erection as hard as diamonds was laying on top of  Lilos belly. 

*My god…*

Nani was so immensely wrought with such an intense and powerful lust her mind didn't even notice that she seemingly just pounced on top of her sister. Nani looked directly downwards to see her sister's face meet her own. It was an adorable face of youth and wonder, her disheveled hair covering an eye. They both blankly stared at each other for a moment. It felt like an eternity but Nani didn't mind the view.

Nanis hair was drooping down besides Lilo's face, plump breasts casting shadow over her small body. Nani leaned in closer towards Lilo until their faces barely touched, slowly inching towards her till their noses met staring at each other's eyes. Purely blank expressions looking at each other with Lilo looking ever so slightly more concerned staring at her bigger sister who completely dwarfed her small body, casting and towering over her as they closely stared at each other until she felt the slightest hint of touch against her lips and felt an instant jolt of pure shock and confusion. Nani further lowered her lips towards lilo until-

“PFFFT hahahah!” Lilo just started chuckling at her sister. “hehehe  HAHAHA”  then it became a laugh. A laugh powerful enough to cause the girl to make a piglike snort sound. Nani found it adorable enough to where it wasn’t a total mood breaker to the lustful aura around them, just seeing her cute precious Lilo genuinely smiling and having fun was enough to make whatever happens that day to feel like it was worth it all the while forgetting that her erection was still laying on top her pudgy belly, its stench and musk radiating and infecting her body. 

“Haha so now we finally get to play house! Shoulda told me already you know i've wanted to play this with you forever!”

She snickered and snorted like a pig having the time of its life finally getting to play with her sister she assumed.

Nani took this opportunity with a grin

“Alright  then” she stared at Lilo accepting the offer “ill be the husband then” 

“Huh but I wanted to be the daddy? He gets to do all the fun stuff while I'd just stay home cleaning. Why do you wanna be the dad anyway”

“Oh c'mon Lilo it's only fair, I have this thing after all” she said as she flopped her meat about “and plus… …. You got a cute butt.”

“.....huh?” Lilo was caught off guard and had to think over what she just heard. “My….. butt? ….. My butt? Hehehehe HAHAHAHA” she started laughing, Nani soon joined in with her. “My butt huh…. That's weird, you're weird” Lilo was far too innocent to understand the appreciation some had for the rear ends of others. All she knew was that her dad liked her mothers butt and so Lilo would joke about it and that Nani had a similar feeling towards to buttocks of female strangers outside, it was fairly normal to catch her staring sometimes which she found funny laughing at her sister and making things awkward for her if she were ever caught.

“Well” she smugly smiled as ideas ran through her head“if I don't have to clean up and get dressed then you can play with my butt”

Normally Nani would find herself agitated at her sister for trying to get out of being disciplined and being so out of control by bargaining but in this moment of weakness against what the back of her mind was telling her she instead succumbed to temptation.

“Ugh ok fine but JUST this once ok! Don't make it a habit, promise me!”

“I promise heheh” she chuckled as she turned around under her sister with a grin on her face. Nani couldn't tell what was cuter her attitude or the way her butt had a slight jiggle to it with even the slightest amount of movement. Enticing her to give in and do whatever she pleases to it

SMACK

“HEY! That hurt!I'm the mommy! You can't spank mom!”

Nani laughed at such a statement “well that's to bad, its my house” smack “and mommy made a mess” 

Lilo was wincing and gritting her teeth as her butt wobbled from side to side as Nani slapped it across before getting a handful of her cheeks and rubbing it with her hands, kneading her butt as if it was dough. Lilo has been spanked  before but this was much less painful and there was much less massaging. Lilo felt her buttocks become spread apart revealing her hole, it feeling sensitive and exposed.

Nani wanted to really dive in and devour what she considered such a pretty thing but knew she would have to take some precautions before doing such while at the same time wanting to tame her erection quickly and coming to a compromise. Now on her knees and furiously pumping at her erection angled and aimed right at her butt with her right hand while her left hand kept those cheeks open for her to gaze at. Her rump now being used as masturbation fuel for the degenerate sister. 

Foreskin being pulled back and forth and pumping at a rapid pace, Lilo could hear her sister grunting as she was laying on the floor on her belly with her back exposed confused at just what her sister was doing. The floor got warmer as she was puzzled and tried turning her head to see just what she was doing as she could only see her sister in the corner of her eye as she kept making strange noises as if she was getting tired of being hurt.

HMMPH HHMMPH UMMMMF

 It was making Lilo somewhat uncomfortable hearing her sister make such sounds. Was she ok, she thought? Was she mad at her? Was she exercising? As such thoughts dwelled in her mind she started squirming at the sudden wet and sticky sensation she felt on her back and all over her butt as if she was just splashed with something and then she started feeling it around her legs and right on top of her hole as well. It was so sudden and unexpected that she twitched at the feeling, as if she was just spit on by her sister

“What are you doing?!” She finally turned around to see her sister, the slimy feeling sticking to her body as she sat down on her butt against the floor and was surprised to see her sister look upset for some reason before hearing her say

…. What the hell am I doing
