Work Text:
There's a special kind of bond that only grows between siblings, a form of connection that can be stronger than almost anything. Loyalty, care, devotion, selflessness, all combined into a mixed feeling that transcends almost any limit.
For a love that can grow that strong and deep, morality suddenly becomes something more keen to a suggestion than a principle, and rules, no matter how big the consequences for breaking them might be, are simply an inconvenience.
At some point in your life you realize that you'd do anything for your sibling, no matter how difficult, painful, or sinful. You realize that the closest thing anyone can ever have to a soulmate is this. True, unconditional love for your own flesh and blood, even if it goes past what morality and "rules" dictate is acceptable.
Vi was never a big fan of rules in general. Being a poor kid that had to manage a chaotic life with parents that were almost never at home during her whole childhood, she learned quickly that life isn't fair, and that playing by the rules wouldn't get her very far.
Morality however was a bigger hindrance...
She has always loved her little sister, her sweet Pow-Pow. She practically raised them both, trying her best to give her little spark of joy a better childhood than the one she had. Powder, so small and fragile, has been the sole reason why Vi has endured every bad thing that has come her way.
To her, the mere thought of losing that tiny blue drop of happiness would mean losing herself, so she decided to hold Powder as close and as tight as she could, figuratively and literally.
It's not like there was anything keeping them apart to begin with. With their parents out for sometimes whole weeks to work on the mines, (or to do only god knows what they got up to in the meantime) Vi and Powder had plenty of time to spend with each other.
Vi loved it. The bootleg, cheap DVDs, the microwaved popcorn, the orange colored soda that you'd be lucky to find any trace of actual orange juice in it. All of it felt like precious little memories of the time she spent with her baby sister.
To her that was perfect, and if you added in an actual job so she could take powder to live with her instead of their parents, it would be the everything she could've asked for. Or at least that's what she thought.
At the tender age of 17, Vi was a ticking bomb of hormones and pent up rage from all the fights she keeps getting herself into at school. Powder, barely 12, had just started developing into what would one day become a very beautiful woman, and that is when Vi's morality was put to the test for the first time.
It was a Saturday morning, She woke up on the couch as it customarily happens whenever they marathon Powder's favorite DVD, a Torrent copy of the second season of Adventure Time in all its glorious 480p to fit all episodes in a single disk.
Powder loved that show almost as much as she loved to cuddle with her big sister, and to no one's surprise, she prefers to be the little spoon.
So, when Vi woke up to the smell of blueberry shampoo on her nose, it was nothing new. What was new, however, was the subtle, but clearly noticeable bulge in the front of Powder's pajama pants, which like most of her clothes, were just a bit too loose on her skinny body, consequence of being handouts from Vi.
So when the blooming traces of puberty manifested under her sister's clothes, it was hard not to notice it, especially when Vi accidentally ran her hand over it. And lying just under where Vi's fingers stopped still on her cute little belly, was a small tent, and underneath it, Powder's pre-teen, fully erect penis.
Vi froze, her heart picking up in pace like she was about to get mugged in an alley. Her breath caught, and for a good few seconds she couldn't formulate a single coherent thought.
She knew Powder was... Maturing. After all, it's literally inevitable, but to actually feel it like this? It caught her off guard, way off guard.
Powder barely has hips, barely has breasts, and since they showered together until fairly recently, she knows that she doesn't have any hair down there yet as well.
'Could this be... Her first erection?' Vi thought to herself, finally learning how to breathe again.
Vi couldn't know for sure. She wasn't born like Powder, but from what she recalls it took her quite a while to start feeling anything different downstairs. Perhaps Powder's anatomy helped her in that regard, or perhaps...
'No! That's ridiculous' Vi quickly shushed her own thoughts, which wondered if her sister's "reaction" couldn't have been caused by an "external factor", read it, having a practically fully grown woman hugging, caressing, and squeezing her every chance she gets.
Vi has earned a reputation for being rough, grumpy, and overall violent, but if there ever was an exception to that rule, it was Powder. She cuddles her, kisses her multiple times a day, loves to touch her soft skin, not to mention their shared intimacy. Showering together has only turned into a problem because their parents pointed it out a few weeks ago. If it was up to Vi, she'd still be sharing every possible waking moment of her days next to Powder.
So when the thought of how that closeness might have been affecting Powder this whole time surged inside her head, it truly hurt her.
'It can't be that!' She insisted, knowing that even if she's more affectionate than big sisters usually are towards their siblings, it couldn't have awakened a reaction like that one.
'Powder's too innocent to see any malice in what we do. She can't get... Aroused, and even if she did, what we do is normal. And she's still a kid, for Christ sake!'
'A kid with a hard dick' A voice in the back of her mind said, and that's when she realized that her hand was still exactly where she left it.
She moved her head a little to see the tips of her calloused fingers still brushing lightly against the stretched fabric, beneath which Powder's immature boner rested, waiting for release.
That thought makes her swallow a lump. What the hell was she thinking? She's not supposed to interfere with her sister's sexual development, period.
Whatever is happening inside Powder's body should only concern her and her alone. Still, she didn't pull her hand back.
A few more minutes passed by, and so did a lot of new thoughts inside Vi's head.
'Powder's growing up...'
'She's growing up fast...'
'Faster than I thought...'
'Soon she'll start to explore these new feelings...'
'She'll learn to touch herself...'
'She will start thinking about sex...'
'She'll ask me questions... Yeah, that's how she is... Always curious about everything, and always relying on me to help her when she doesn't understand something... Or when she's scared...'
'This will probably make her scared...'
'I know it was kinda scary for me...'
'I had no one to tell me what the fuck was going on with my body... I don't want her to go through that...'
'She doesn't have to'
'What?'
'She has you'
'She... No, no, that's beyond wrong. That's Taboo with the capital 'T'. I can't...'
'If not you, then who? Someone's gonna do it. Mom? Dad? Pornhub? She's smart, she'll look for answers, and if you don't give them...'
'I can't touch her like that!'
'Not like this. But if you get her permission...'
'What?!'
'Show her that she doesn't have to be afraid. Show her that you're here for her...'
'I... I-'
"Hmn..." At that moment, Powder's soft grunts brought Vi back to reality.
That's when she finally pulled her hand back, letting Powder wake up to nothing but an ordinary Saturday morning on the couch.
"... Morning, Vi..." The tiny girl said, her voice feeling like a blessing and a curse in Vi's ears.
"Morning, Pow-Pow" She whispered back, scolding herself for the thoughts she was just having about her sister not even a minute ago.
If Powder noticed (and Vi was pretty damn sure she would've noticed) the current state of her penis, she didn't comment on it, probably out of embarrassment. Either way, they started their day as if nothing ever happened.
***
But something, of course, did happen. And Vi, as good as she was at repeating to herself that she wouldn't have gone any further if Powder didn't wake up, continued to be haunted by those same sinful thoughts as the days went on.
Soon it became evident to her that this wasn't about Powder, at least not entirely. The following weeks left some things pretty clear.
First, Vi could no longer look at Powder in the eyes, not without feeling ashamed for her desire; Second, yes, Vi realized that she desired to touch Powder again, much to her displeasure; Third, it was becoming more and more evident that she was fighting a losing battle against her own moral compass, because despite not being able to look at her sister in the eyes, she had become even more affectionate with her.
From that day on, Vi has gotten even more clingy with Powder. If she could be in direct contact with her baby sister at any time, then she would, no exceptions. She kissed her more, sometimes even getting the corner of her lips on "accident", not to mention her caresses, that got bolder and bolder. Touching Powder's legs had turned into a habit wherever they were sitting together at the couch, and of course, having any fabric between them was unacceptable during those idle caresses. Lucky her it was almost Summer, that way Vi didn't need an excuse to have powder in shorts all day.
And Powder? Powder loved it, and Vi knew exactly why.
It didn't take long for her to realize that Powder's morning wood was a regular occurrence now, and despite not daring to touch her there again, she never made any attempts to stop it.
Actually, whenever she woke up to a bulge in her sister's pants, she actively tried to encourage it. Running her hands over Powder's arms and legs, planting soft kisses on her neck, and even licking her sisters earlobe once.
She felt like dirt at the very moment she started, but soon that feeling was replaced by a surge of pride when Powder started to buck her hips to chase whatever friction she could get in her slumbering state.
It was wrong, deprived, incestuous, perverted, you name it. Vi knows she did. Mentally she called herself all kinds of slurs and more, but even her self hatred wasn't enough to make her stop.
After all, Powder is her sister. Hers to take care of, to protect and if this is where they're at, to make her feel good. Yeah, that's what this is, she's just making her sister enjoy herself. No harm done, not if she doesn't cross the line.
Unfortunately for her, destiny has a funny way to make us confront our temptations.
It was Friday night, almost three weeks since their first incident. They were watching Pirates of the Caribbean on the couch, the popcorn resting on Powder's lap as vi held her with an arm around her shoulder.
"You think they'll be back sooner this time?" Powder asked, referring to their parents, who just left again that morning after a record 5 straight days at home.
"Don't know, Pow-Pow. It's their job..." Vi said, trying her best to fake interest in her parents' whereabouts, but secretly wishing they never return.
The last five days have been rough on her. Not being able to hold Powder as much as she got used to while they were close, and that's not to mention school, which meant even more time apart. The only relief she got was that they still slept together, so every morning powder had that tentative little gift for vi to admire whilst she worshipped her sister's pristine silk smooth skin.
She even thinks Powder might've come this morning, but it was hard to tell when she didn't allow herself to pull her sister's pants down. That, and there's also the fact that Powder might not even be able to produce anything yet. Still, she squirmed so cutely that Vi just couldn't help but rub one off in the bathroom that morning.
She usually masturbates only once or twice a month, but ever since that morning it has been almost a daily ritual. Always thinking about Powder, of course.
"Oh... I wish they didn't have to work so much" The young girl commented.
"Yeah, me too..." Vi lied, then squeezed Powder's shoulder and placed a few kisses at the top of her head "But don't worry, okay? I'll always be here to take care of you" She added with a smile, and Powder looked up to meet her sister's eyes.
"Promise?" She asked.
Vi wanted to avoid her innocent gaze, so pure that it was almost infuriating how easy it would be to manipulate her if she wanted to. Still, she didn't look away, just leaned in to press their foreheads.
"I promise. I'll always be here for you" She whispered, then rubbed the tips of their noses a few times, which got a few giggles out of Powder.
"I love you, Vi" Said the little girl.
"I love you too" Vi easily responded, and for a few moments it felt like that was it. Vi turned her head back forward and tried to focus on the movie. And then Powder spoke again.
"Vi?" She called, almost like a whisper.
"Yeah?" She turned to face her again.
This time Power was the one having a hard time with eye contact, and she didn't try to hide it at all.
"What is it, Pow-Pow?" Vi leaned in again, her voice as soft as she could make it.
"Have..." The little girl was holding the hem of her sleeve now, arms crossed as she was clearly nervous to continue that phrase. Still, she went on "Have you ever felt... Strange?" She asked, and Vi furrowed her brows.
"Strange how?" The pink haired girl asked, and after a moment of nothing but the movie making a sound, she reached a hand to cup her sister's cheek "Hey, it's okay. You can tell me everything, remember?"
Powder looked at her sister, eyes slightly watered, but she didn't seem sad, or scared. No, Vi knew that face, she was embarrassed.
"Strange... Down there" She looked down at her own lap, blocked from view by the bucket "Does it ever feel... Different?" She asked, and for a second, Vi couldn't breathe.
She knew this moment would come. The moment where Powder would come to her asking for answers about her body. The moment she could give her advice, explanations, to make her feel safe about her own sexuality. The moment where she would have to explain that anyone touching her in ways that looked a lot like how Vi touches her is wrong.
"D-different how?" Vi almost choked with those words, but still managed a welcoming smile.
This is it. She's about to put an end to it. Once she tells powder what's going on with her, she'll tell her that from now on they shouldn't be as close as they have been. That this isn't healthy, and that a sister should never-
"Powder, what-" Vi's words died in her mouth as Powder quickly moved there bucket out of the way, stood with her knees on the couch and unceremoniously pulled her pants and underwear down to reveal her 4 inch erection pointed straight at Vi's face.
"It's been getting like this..." The young girl said in a slightly exasperated voice "I don't know why, but I can't control it, and... There was this... Stuff. At first I thought I had wet the bed, but it wasn't pee. I-it was white and sticky, and... Vi, am I sick?" She finished, but Vi barely had the presence of mind to hear a single word.
Her eyes were laser focused on Powder's dick, hanging free for her to see. Completely hairless, barely any hint of veins bulging across her length, and to top it all off, the head was still half covered with her foreskin. It was, without a shadow of a doubt, the cutest thing Vi's ever seen in her life.
"Uh- What?" She blinked, looking up at her sister's insecure face.
"Vi, am I sick? Is this normal? It keeps getting like this, and I..." She was almost crying right now, so Vi got up to meet her at eye level.
"Hey, hey. It's okay. You're not sick. This is... This is totally normal. It just means you're growing up" She said with a soft smile.
"Really?" Powder managed, holding back her tears and mustering up a timid smile.
Vi nodded.
"This is totally natural, Pow-Pow. There's nothing to feel bad about" She reassured, holding her sister's shoulders.
"Okay..." She sighed in relief, then looked down "But then what is it? Why is it like this?" She asked, and as Vi's gaze followed hers back to her sister's small shaft.
"That... Um... Well, it happens to signify that your body is ready to... Make babies"
"What?" Powder frowned, looking at Vi's face and then at her member again "How?"
"That's not..." Vi began, trying and failing not to be distracted by her sister's boner as it moved with each turn of Powder's hips.
The object of her desire, so close to her, so impossibly ready to be worshipped like she did the rest of Powder's body. Vi couldn't believe it, but the thought of touching it alone made her mouth water.
"Tell me..." The young girl said with a whine.
Vi blinked a few times, then faced her sister again.
"To make a baby, someone has to put their penis into someone else's vagina until it reaches an orgasm. That's why it gets hard, so it can get inside and... That's when it releases that white stuff you talked about..." Vi timidly managed to explain.
"Orgasm?"
"It's like... You know when someone starts to tickle you, and you want them to stop, but at the same time it feels kinda nice?"
"Like when you tickle me?"
"I... Yeah, like that. It's like that, but just the good part. It makes you feel really good, and that's... That's what sex is"
"Oh... So if I feel good enough it comes out again?"
"Yeah"
"That's why it came out when you were kissing me this morning?"
"What?"
"In my bed, when you woke up... I just thought you were happy and wanted to kiss me. And it was already hard then, so I didn't want to make any noise so you wouldn't see it. But then you kept kissing me, and before I knew it..."
'Oh my god... I made her come... I did it, and she knows it...'
"P-Powder, I..."
"Can you do it again?" The girl simply asked "I was kinda scared back then, so I couldn't pay much attention to it, but it felt really good..."
Vi looked at her face, then her dick, then her face again, her heart beating like it wanted to burst her chest open. She licked her lips, then took a deep breath.
"Pow-Pow, I can't... Sex isn't something that siblings should do, like never do, okay?"
"But that's not sex... You said that I'd have to put it inside your... Well, this is just kissing. You kiss me all the time" The girl argued.
"I know... Still, it doesn't mean it's right. If you want to have an orgasm again, then you should... You should do it yourself"
"But I don't know how. I can't kiss myself"
"You don't have to-... Look..." Vi reached a hand to hold one of Powder's wrists, then guided it to her erection "Just hold it, okay? Not too hard, not too soft..."
Powder squirming a little at the contract.
'Fuck, she must be so sensitive...' Vi thought.
"Like this?" The girl asked, and Vi nodded.
"Now, you just rub it until you start to feel good, okay" She instructed, and so her sister obliged.
A couple of minutes went by, filled with awkward silence and a few grunts, until eventually...
"Vi... I don't think I'm doing it right..." Powder finally said, clumsily stroking her small length up and down "It's not working... Can't you show me how it's done?"
"Me?" She asked, already dripping wet from watching her sister masturbating for the first time "Powder, I don't have a..."
"Use your hand on mine" She said, letting go of her erection in a motion that made it wiggle a bit.
Vi was already chewing her own tongue to keep herself at bay, and then she saw her sister's pleading eyes.
"Please... I just need you to show me"
"Pow, I can't... I told you. Siblings can't-"
"I won't tell anyone. I just need you to help me"
"I... I'm not sure"
"Come on, you did it this morning and you weren't even touching it! Clearly you're doing something right, so can you just do it again?"
A moment passed, then another, and finally the dam that Vi has been trying so hard to keep standing, crumbled to a million pieces. She closed her eyes one last time, and when she finally opened them, she had made up her mind.
"Okay. Lie down..." She said, her voice firm, masking her anticipation as Powder's eyes sparkled with joy.
The girl was lying with her back on the couch in a nanosecond, her cock pointing up like a candle in a birthday cake.
Vi crawled on top of her, standing with her face barely an inch away from her sister's inviting shaft. Then, she looked up at Powder's slightly nervous, but extremely eager expression.
"I'm gonna try something, it should be quicker this way. If you feel anything weird or uncomfortable, you say it immediately, and I'll stop, okay?" She asked, although she wasn't sure she could uphold that promise, she still felt like she should make it regardless.
Powder just nodded.
And then Vi lowered her head, she moved down until her lips found the skin of Powder's hairless crotch, taking in the scent of her sisters blooming sex as it rested against her cheek.
She kissed Powder's skin, once, twice, three times, and many, many more after that. She circled around her sister's cock until she found her petite ball sack, not bigger than a golf ball. And that's when the urge to taste her sister's sex became too strong to overcome.
With a voracity she never felt towards the best foods she's ever tasted, she took Powder's testicles inside her mouth, letting out a loud moan as she did so. Powder, half shocked and utterly stunned, didn't waste any time meeting her sister's noises as she arched her back on the couch.
"Viiii~" There young girl moaned.
Vi savored the sound of Powder's voice as if it was the trumpets of heaven themselves. She licked and sucked her sister's small testicles like they wer the rarest, most delicious treats in the world, and to Vi, they might as well be.
She was so focused on her work that she barely noticed when Powder's hands rested on her head. To her, this was paradise, and it was just the beginning.
Without stopping her ministrations on Powder's balls, Vi reached a hand under her pants, and one to hold Powder's dick. That got Powder's attention, and as she looked down at her sister's face, she found Vi's piercing gaze staring back.
Her sister's mouth was sucking her balls whilst her hand was holding her dick. Whatever Vi meant by this being wrong before, it suddenly started to make much more sense in Powder's head. Whatever this is, it feels wrong, even Powder can feel that.
And still, she doesn't want it to stop for nothing in this world.
"Vi... Oh my god..." She gasped, feeling her hands move in tandem with Vi's motions.
The older sister was not wasting any time either. Her left hand was working fast on her damp sex, rubbing circles on her clit as if she was trying to create fire with the friction.
That didn't make her neglect her sister's delicious treat though. Releasing Powder's testicles with an audible 'pop', she started stroking her dick at a slow and steady pace. Powder was already a moaning mess on her hands, and Vi barely had to try.
She should've known it wouldn't take a lot to please her when her kisses alone brought her to the edge. That thought still makes her as proud as professional athlete that just broke a record.
"So... How does it feel, Pow-Pow?" She asked, a smug grin on her face as she jerked her sister off without a care in the world.
To the hell with rules and morality. Powder's her sister, hers to do as she pleases, and no one will ever change that.
Powder looked down at Vi, although keeping her eyes open was kind of a challenge in of itself.
She didn't speak, couldn't, so she just nodded, holding back a moan as Vi started rubbing her thumb over the pre cum in Powder's tip, which soon was replaced by her tongue.
She circled the entire underside of her sisters silk smooth foreskin whilst kissing her glans passionately. She didn't intend to overwhelm Powder like this, but fuck it, she's been longing for this for too long. She licked, kissed, sucked, and got so entranced into the feeling of Powder's pre-teen dick that she was shocked by how long it was taking Powder to cum.
That's when she looked up and saw that Powder was making a face, her hands holding tight into the couch's fabric as she fought back the urge for release.
'She's trying to drag this down' Vi realized 'Oh, baby. You really think I'll stop after you come?'
With a knowing smirk, she started pumping her sister's meat much faster than before. Powder grunted, still trying to prolong this.
"Uh uh uh... Don't hold it back" She said, increasing her pace "I wanna hear all of you, Pow-Pow. I want to scream for me"
"Ughn~" She whimpered, and Vi smiled wide.
"Louder" She demanded.
"A-agh!..." The girl voiced out.
"Louder..." Vi repeated, feeling her own climax approaching as she stroked Powder into oblivion.
"VIIIIII~!!!" Powder finally screamed, and without missing a beat, Vi took her cock in her mouth, only to feel the sweet release of her sister's essence filling her mouth, even if there wasn't much in terms of volume, the feeling of Powder's cum felt like it could take her to space and back.
And apparently it did, because the feeling of Powder's twitching, cum leaking cock inside her mouth was the last push she needed to reach her own climax.
Her hips bucked against the couch, riding her high with spams and grunts from a place so deep inside her throat that Vi was sure she sounded like an animal right now. She didn't care. Nor did she stop sucking on Powder's cock for that matter.
Even after they were both back from that trip to cloud 9, she continued sucking, feeling it soften and then get hard again inside her mouth.
"Vi... I think I'm good already... You don't have to- Ughn!" Powder tried to say, but vi just shook her head, before pulling back just enough so she could speak.
"Don't worry, baby... I'll take care of you..." She said, kissing the tip of Powder's cock tenderly "From now on I'll always take care of you, okay? Just leave it to me. I'm gonna make you feel so good, Pow-Pow" She whispered those last words out before going back to her work.
Powder moaned, feeling a light tinge of discomfort as Vi continued to work on her dick. She could've asked her to stop, but she didn't.
She came about 5 more times that night, not protesting even once.
She didn't ask vi to stop, she would never ask Vi to stop.
