Hinata and Hanabi by Imouto Kitten

It had been a long week for Hyuga Hinata, and taking a long soak in her 
private bath at the Hyuga Compound had only partly relieved the young 
kunoichi of the tension that had been building within her. The C-rank 
escort mission she had returned from earlier that day hadn't been 
particularly hard, at least not on its own.

What had made it hard was that the merchant they had been hired to 
protect from bandits was accompanied by his young and rather attractive 
daughter, a fact that had left Hinata hot and bothered for most of the 
mission and unable to relieve herself as she struggled to keep the fact 
that she inherited the Hyuga's rarer and less useful in combat kekkei 
genkai.

Even as she steps out of her bathroom into her bed chamber, Hinata can 
feel herself starting to tent the simple, white sleeping yukata she had 
donned after her bath as she thinks about the young girl she had needed 
to protect, as much from herself as from bandits interested in more than 
money.

Laying upon her large futon, Hinata undoes the sash of her robe, 
allowing her foot long futahood to stand up straight, the thick, 
throbbing appendage that maybe one out of every hundred Hyuga women was 
blessed, or cursed, depending on perspective, with aching in need, the 
young heiress nearly in agony from a week's worth of pent up sexual 
frustration.

Gripping her cucumber-thick shaft with both of her dainty hands, failing 
to even come close to fully enclosing her massive member, Hinata starts 
to vigorously stroke herself as she imagines what that merchant's 
daughter might look like stripped of all clothing and spreading her arms 
and legs in invitation, Hinata occasionally using a modified form of 
gentle fist to send chakra from her palms into her erection, working 
with the natural flow through the coils running along her shaft to 
enhance the sensations.

However, as Hinata starts to imagine the merchant's daughter trying to 
fit the Hyuga's huge hermaphrodite hard-on in her tiny, virgin pussy, a 
knock on her bedroom door snaps Hinata out of her lustful trance.

Suppressing a grown of frustration, Hinata climbs to her feet and 
adjusts her yukata to cover her futahood before heading to the door.

Sliding the door open, Hinata is met with her younger sister, the 
shorter Hyuga in nothing but a simple, white silk nightie of a style 
Hinata is sure their father would disapprove of if he knew Hanabi owned 
it on grounds of it not being traditional enough.

"Wh-what brings you here so late, Hana-chan?" Asks Hinata, worried that 
her sister will notice the tent in her Yukata, a tent that's quickly 
becoming harder to hide as she realizes that, aside from Hanabi's way 
too serious for a girl her age expression and the trademark pale eyes 
that nearly all Hyuga share, the younger kunoichi bears a striking 
resemblance to the merchant's daughter that was just fueling Hinata's 
fantasies.

Crossing her arms over her diaphram as if trying to emphasize the bust 
she doesn't have, Hanabi leans against Hinata's door frame as she 
answers bluntly, "I'm here to help you take care of what you're trying 
to hide under your yukata."

"I...I do-don't know what you're talking about." stammers the older girl 
in denial.

Balling her hands into fists at her sides, Hanabi retorts, "Come on, 
Onee-sama, even if you weren't doing an awful job of concealing it, my 
Byakugan can see your erection as clearly as if you were naked, and 
these walls might as well be glass for all the privacy they provide with 
nearly everyone in the place having Byakugan. No wonder father has been 
debating which of us to name heiress, but enough of that, my cunt craves 
cock, and you can either let me take care of your sexual needs or I'll 
take what I want by force."

With that, Hanabi shoves her older sister back into the bedroom and 
follows her in, slamming the door behind her.

Her need to release the cumload she's been building up for the last week 
winning out over any concerns about incest, Hinata puts up little 
resistence as her younger sister guides her to her futon and pushes the 
older girl onto the mattress.

Kneeling between Hinata's thighs, Hanabi makes quick work of undoing her 
sister's robes, and as Hinata's erection is exposed to the air once 
more, Hanabi wastes no time in wrapping her hands around the massive 
member and lowering her mouth to the throbbing tip, swirling her tongue 
around it.

Hinata is soon moaning quite loudly, digging her hands into her mattress 
as her little sister alternates between suckling her tip, stroking her 
shaft, and giving her long licks that start at her base, if not her 
pussy and go all the way up to her tip.

Once satisfied that she's sufficiently lubed up her sister's futahood, 
Hanabi rises to her knees and straddles Hinata's hips, her pussy kissing 
the tip of her older sister's futahood, the older girl's shaft nearly as 
thick as the younger girl's thigh. As Hanabi starts to bear down, 
Hinata's girlcock meets quite a bit of resistance, Hanabi wincing a bit 
as her opening tries to stretch around the cock head pressing against 
it.

Noticing her little sister's expression, a worried Hinata comments, 
"Ha-Hana-chan, yo-you don't need to force your self."

"Shut up Onee-sama!" yells Hanabi in response, putting her full weight 
upon her sister's futahood, grunting as her opening spreads to 
accomodate the massive intruder, her hymen stretching under the pressure 
put upon it.

By the time Hanabi has forced her sister's massive member cervix deep 
within her, her passage stretched to a point she'd be sure it was on the 
verge of snapping if not for the knowledge of how childbirth works, the 
younger Hyuga is panting heavily from the exertion.

Glancing down, her Byakugan seeing through her nightie as if the garment 
wasn't there, Hanabi is shocked to see that only half of Hinata's 
monster member is inside her, though she does a good job of hiding her 
surprise as she starts to slowly rise and fall upon the prodigious 
prick, a mixture of pain and pleasure pulsing through the girl's petite 
frame as her insides struggle to adjust.

Despite Hanabi's impatience, her juices eventually start flowing enough 
and her internal muscles relax enough to allow her to easily slide up 
and down her sister's steely shaft, pain giving way to pleasure and a 
sense of pride filling the young girl as she reduces her elder sister to 
a moaning, panting mess beneath her.

But while Hinata is absolutely shameless about how much she's enjoying 
her cute, little sister riding her girlcock, the younger Hyuga does her 
best to maintain the stoicism the clan is famous for, biting the inside 
of her cheek to avoid crying out even as every downward thrust of her 
hips forces her failure of a sister's futahood deeper within her, the 
tip of Hinata's hardon hammering Hanabi's cervix with ever increasing 
pressure.

Naturally, it isn't long before Hinata cries out, "Ha-Hana-chan, I-I'm 
going... I'm going to erupt!"

"Yes, Onee-sama, spill your seed in my belly." replies Hanabi with 
forced calmness, her excitement nearly at its zenith, "In fact, lets 
watch with Byakugan as you flood my womb." as she glances down to her 
trim tummy, focusing her eyes to do just that.

When Hinata focuses her own byakugan to observe her little sister's 
reproductive organs, the older Hyuga spots something that makes her go 
even paler than is normal for the clan, a tiny speck of chakra that 
belongs to neither sister drifting from one of Hanabi's ovaries towards 
the young girl's womb.

"Hana-chan!" cries Hinata, nearly in a panic,"You need to get off, you 
have an egg on it's way to your womb!"

As Hinata tries to grab Hanabi's hips to throw the smaller girl off, the 
younger, but more skilled girl's hands fly into a flurry, the younger 
sister quickly subjecting the older sister to Eight Trigrams: Sixty-Four 
Palms.

Paralyzed by her clan's signature technique, Hinata can only watch 
helplessly as Hanabi redoubles her efforts, the older Hyuga not even 
able to muster a verbal protest as her orgasm rushes towards her. And 
then it's there, as with a final drop of her hips, Hanabi forces her 
cervix down over Hinata's cock head, that innermost gateway forming a 
tight seal around the collar of the futa's prick as it begins to erupt 
great gooey gobs of potent, life-giving seed directly into the younger 
girl's fertile, unprotected womb, the sensation sending Hanabi into a 
climax of her own, her passage rippling around her sister's shaft, 
milking the older girl for all she's worth, the younger girl finally 
crying out in euphoria even as her older sister remains silent, even her 
vocal cords paralyzed by her little sister's gentle fist assault.

As both sisters come down from their shared climax, Hanabi collapses 
atop of Hinata, making no effort to pull out the cock plugging up her 
cum-filled womb.

When the natural flow of her chakra has reasserted itself enough for 
Hinata to speak, the first thing to slip through her lips is, "Wh-why? 
Why did you do this, Hana-chan?"

"I did it to save us both, Onee-sama." replies Hanabi, her tone much 
more gentle than is typical of the little girl who so frequently lives 
up to her name meaning 'firecracker'.

"Sa-Save us?" Asks hinata, confused, "Save us from what?"

"The caged bird seal, Onee-sama no baka!" spits the young girl, slamming 
a fist into the mattress, "Don't you get it! Whoever of us Father 
doesn't pick as heiress will be branded with that atrocious mark and 
forever be a slave to the other!" Calming down, she continues, "But if I 
have Onee-sama's baby, then whoever Father chooses can claim the other 
as their consort, and neither of us need suffer a life-time of 
subgegation to our own sister"

As Hanabi collapses against her again, the little girl finally letting 
tears fall at the thought of the fate she hopes this night's events have 
averted, Hinata wraps her arms around her little sister and whispers 
gently, "Thank you, Hana-chan, I'd be happy to raise a family with 
you... and if by some miracle Father does pick me as heiress, I promise, 
I'll never allow any of our children be subjected to that vile seal."

"Re-Really?" asks Hanabi, sounding more like her big sister than herself 
as she wipes away her tears.

"I promise," affirms Hinata, "and like the boy I admire most, I never go 
back on my word."

With that, Hanabi gives her big sister a genuine smile, an expression 
Hinata is not sure she's ever seen on her overserious little sister but 
silently vows she'll do her best to see more of as while Hanabi was cute 
despite the frequent scowling, she's downright radient with a smile.

At that moment, both sisters let out loud yawns, and realizing just how 
late it is, Hinata offers, "Hana-chan, would you like to sleep with me 
tonight?"

"Yeah," replies Hanabi, "besides, my current bedding is way too warm and 
comfy to move from."

At the realization of Hanabi's secret meaning, Hinata can't help 
giggling even as her cheeks are dusted pink, and pulling the covers over 
both of them, the pair are soon asleep in a mutual embrace, Hinata's 
futahood still plugging up the younger girl's womb to ensure not a drop 
of semen can escape before Hinata's sperm can swarm Hanabi's egg.
