"Oh Ka-chin... *sniff, sniff*" The rather plain looking prince named Fugetsu Hui Guo Rou wiped her tears away while stifling a particularly raunchy belch. Her stomach was swollen, stuffed to the brim with the remains of her dear twin sister and fellow prince, Kacho Hui Guo Rou. After an elaborate escape from the Black Whale ship bound for the new world, the headstrong older sister got a bad feeling in her gut, and decided to use Fugetsu's nen beast ability to retreat, saving them from a would be early demise at the hands of a mysterious higher power pulling the strings. As the two girls crawled through the narrow space back towards the ship, Fugetsu felt a tug stopping her from escaping back to the rather thinly veiled safety of her personal quarters.

"Wait, Fuu-chin. We can't just go back after all of that. I can't bear the thought of us having to..." The usually reliable blonde girl trailed off, biting her lip as she imagined one of them having to kill the other for this horrible succession war that neither wanted a part of. If one of them had to die, then she would rather it be her, right here and right now.

"Sis, you should just-" kill me, you're the one that deserves to live! Fugetsu tried to plea, but a commanding finger stopped her from uttering such nonsense. Her sister smiled as she pulled her dear sibling close, her touch alone calming her nerves.

"Fuu-chin, if anyone is to die here, it will be me... by your hands. Don't start crying, I have a wonderful plan that will ensure that we always remain together~" There was a playfulness to Kacho's mad words that Fugetsu could never hope to understand, but she pulled herself together, knowing that her sister always knew best.

"BWOORHUUUUURRRRPP! Ohhhhh Ka-chin..." The sole remaining sister moaned as she massaged the ball of churning flesh now resting heavily in her lap. She was powerless to stop Kacho as she dove headfirst down her lips, forcing her way inside without elaboration. Her thin body and tasty limbs went down surprisingly easily, until she was safely tucked away in her sister's gut, hidden from sight behind her now much tighter dress. Fugetsu didn't want to admit it, but her sister tasted good... too good. She was still licking her lips, savoring the flavor of her better half that lingered upon them.

Kacho didn't even squirm much once she had been deposited inside. She simply curled herself tightly into a ball, and awaited the inevitable outcome that happened to all freshly consumed food.

Digestion.

The waves of acid that washed over her over the course of the next hour were excruciating, to put it lightly... but she never once howled out for help. Not a single yelp escaped her firmly sealed lips. Why? She wouldn't want her sister to worry. Knowing her, at the first sign of her sister's discomfort, Fugetsu would force herself to hurl, sending a half melted Kacho splattering to the cold floor below. She didn't want to be cold ever again. The warmth she was feeling in the pit of her precious Fuu-chin's stomach... it hurt in a good, almost comforting way. As her body started to break apart, her mind drifted to happier times.

She hoped with all her heart that with this sacrifice, her sister's triumphant return to the nation of Kakin as its next ruler would be her future, with as little bloodshed as possible on her unblemished hands.

GLLLLRRRRRNNNNN

BLOOOOORRRP... GROOOOOOOOOAAN

"Urpff... I'm so sorry, Ka-chin... I'm so sorry you had to feed yourself to your pathetic little sister..." Clutching the sides of the softening swell of excess flesh resting in her lap, Fugetsu's stomach deflated and rounded out further, the meat now fully stripped from her sibling's bones. Just as she was about to rise to her feet to retreat back to the boat with a belly full of sister slop in tow, the sound of a door opening from behind caught her attention.

With eyes as wide as saucers, Fugetsu watched as none other than Kacho Hui Guo Rou emerged from the other side of the door, a smile as wide as the truth plastered on her smug visage. Fugetsu could only blink as her hands squeezed the stomach still sprawled out before her, confirming that Ka-chin was still right there, filling up her lap and dutifully sating her hunger.

"Huh? B-but you... I thought I... huh???" She gasped aloud, only for Kacho to rush forward, hushing her up with a firm finger to her lips like she always did.

"Don't worry about what you thought happened, Fuu-chin! I'm right here, see? And we'll always be together as long as I'm around! Isn't that right?" The forceful blonde wrapped her hands around her dark haired sibling, her hug filling her lungs with her scent. Fugetsu returned the embrace, with her groaning gut squishing between the two of them. As they sat there, simply squeezing one another, another loud churn rang out... not one of digestion, but one of renewed hunger... a sound begging for a hearty second course.

"Okay Fuu-chin, let's gooommphh...?!" Fugetsu's mouth spread quickly over the second Kacho's face, bathing her in botomless darkness. This Kacho's descent into her sister's depths wasn't as smooth and willing as the first, but she was swallowed all the same, her squirming arms and lankly kicking legs a pleasure to slurp down. Fugetsu exhaled a sigh of relief as her gut expanded with the shape of another sister, the second now squirming amongst the slop of the first. She knew she had to get back to the boat soon before anyone realized she was gone, but she could not help simply sitting there, her fingers and palms gliding over the bumpy surface of her distended gut.

"Ohhhhh Kaaaaaa-chiiiiiin... You were really too tasty for your own bhuuuuuuurrrp good~" Her stomach tightened around Kacho, stopping her squirms dead in their tracks. All the helpless blonde could do was scream for help, begging her sister to release her. She was here to help her escape and survive, not nourish her like some sort of feast! Her cries for release fell on deaf ears, however, as Fugetsu ignored her sister's whining. If she could handle being digested once, what harm could a second time cause? And if she did come back again... well, a third Ka-chin would make for a rather filling dessert~

"Fugetsuuu... FUGETSUUUUUuuuubble..." The scalding acids overtook the blonde, silencing her screams. Soon, smooth sounds of digestion were all that filled the stomach, as the second Kacho was digested just as easily and thoroughly as the first. Her clothes were broken down, as her pretty porcelain skin was stripped from the bone, leaving two identical skulls floating in the slop of two girl's worth of bubbling chyme.

"Mmm... sorry sis. So sorry... sooooo sorryyyy~" Fugetsu felt drunk as her nen beast's ability, Magical Worm, led her safe and sound back to her room. She hid her giant gut under the covers, her eyelids heavy as she easily drifted off to sleep.

In her dream, she was in the snowy mountains with her sister, laughing and playing as they skied down the trail, wide grins plastered on their innocent faces. Her stomach churned and gurgled as both of her sister's identical mass funneled through her intestines, fattening her tiny, lithe frame as she slept. With enhanced proportions to rival even the curviest girls on the boat, and a thick, sister-laden potbelly rising and falling as she snored, Fugetsu dreamed of never being apart from her precious Ka-chin, ever again.

And she wouldn't have to. She had two sister's worth of flab now decorating her sides. The only question on her mind as she woke to find a massive gain in body fat in the morning was what Kacho's nen beast ability could have possibly been? Why had it not shown itself?

Kacho's beast's ability name was "Without You." If either one of the two sisters dies, it takes the form of the deceased. Staying by the side of the other and protecting her until death...

Fugetsu shrugged as she lifted her heavy form, waddling towards the bathroom with only the intention of relieving her heavily packed bowels weighing on her mind. The world nor her dear sister would ever know the double sacrifice Kacho made on that faithful, fattening evening... perhaps for the better.

Here we have an idea I'd been wanting to get for quite some time, made manifest by  MRRATTLEBONES! I'm a huge HxH fan, and I've been keeping up with the manga(yes, even through the endless hiatus), and this sad pairing and outcome of course inspired me to get a degenerate vorish take on the subject at hand! I would warn of spoilers, but if you're reading this, I'd hope you read the story already beforehand... It's been a while anyways, so anime only plebs, my deepest condolences.

Please, let me know what you thought in the comments below!
