It started over such a simple, mundane argument. Kokona couldn’t even remember what it was about, really. All she knew was her big sister was underestimating her yet again, and she had enough of it. Approaching her from behind, with her face twisted into an adorable pout, the silver-haired girl wanted to get one over on her know-it-all older sibling for once, but what could she do to prove that she was truly an adult on equal footing herself? Shun really did know more about being a teacher, so outperforming her there was out of the question. Perhaps she could w-woo sensei and steal him from her, that would teach her real good!

But her body was rail thin and practically curveless next to her bombshell babe of a sister, would he really go for an underdeveloped body like hers? What she needed was curves of her own… and to do that, she’d need meat, and lots of it! Perhaps she could start binging daily at the Black Tortoise Promenade? Their meat buns were to die for… but no, something that would take that long wouldn’t quell her short-sighted anger at her big sis! She wanted to get busty and curvy, like Shun, and she wanted it now!

A thought suddenly popped into her head, something she had heard Kisaki talking about once before… a story of a student who had devoured others whole, and seen immediate gains from digesting them! The thought was absurd at the time, she had reasoned that Kisaki was probably just making it up to scare her back when she was younger, but now that she was looking at her older sister as food rather than a fellow human being… Well, her mouth was certainly watering hard. She approached her with ill intents, her fingers wriggling like a pervert that was getting ready to grope a vulnerable lady in the night, but Shun only had herself to blame for being converted into her little sister’s curves!

She should have treated her better if she didn’t want to wind up as her dinner!

“Hmm? Kokona-chan, what are y-” Shun felt an ominous aura from behind, but it turned out to just be Kokona doing a silly little sentai pose or something. She called her Kokona-chan out of habit, but her fate was sealed as soon as the younger girl snatched her feet out from under her!

“Grrr, I told you not to call me Kokona-chan! Maybe this will teach you not to underestimate me!” Kokona yanked hard, and Shun soon found herself flat on her big butt, her head a little shaken up from the sudden fall! Her back ached from sudden rough-housing, but she could have never imagined what her little sister planned to do to her next.

“Ghnnn, that hurt, young lady! What do you think you’re… doing?!” Shun had no time to react to a slimy wet feeling spreading across her exposed toes. She watched with utter confusion as her younger sister stuffed her cheeks like a kitten overeating with her feet, swallowing her ankles and calves with frightening speed and efficiency. An angry frown overtook the normally composed woman’s face as she tried to pull her legs out with little to no success.

“K-Kokona, I don’t know what’s come over you, but this is completely unbecoming of a young lady like yourself! Release me at once before I get upset!” Kokona ignored her elder’s empty threat, her tongue wrapping around the back of her knees while her teeth eagerly chomped over the joints. Shun scraped at the floor, attempting to regain control of the situation, but her sister seemed to have abnormal strength and determination to swallow her whole! She felt the cold saliva meet her bare, thick thighs, as the warmth of her throat quickly contrasted most sickeningly.

“Sunohara Kokona! This is your last warning! I won’t share any more of my pudding with you if you keep this foolishness up for much longer!”

Another weak, empty threat, Kokona planned to eat all of her big sister’s pudding once she was out of the picture, so who would be around to stop her? Shun will be a little too busy padding out her chest to deal with that~ As delicious as her sister’s bare legs were, they were just appetizers compared to the glazed hams slipping inside her gullet now. Kokona always thought Shun’s butt was big and beautiful, but now that she was sampling it firsthand, she could see why men wanted to get into ladies pants like her sister’s, she tasted absolutely divine! The sweat dripping off of those supple, firm cheeks was the nectar of the gods, and nothing was going to stop her from savoring every inch of big sissy before her.

“K-Kokona, I don’t want to hurt you, but you’re leaving me little choice here!” Shun shouted with a little more fear in her voice as she watched her lower half disappear down the bottomless pit that was her younger sister. She stopped clawing at the ground and refocused her efforts on escaping by pushing against Kokona’s head and pulling her hair, something that was met with a snarl by the girl whose meal was being rudely interrupted. Instead of backing off, Kokona redoubled her swallowing efforts, taking bigger bites and chomps and ignoring tasting her sister in favor of just slurping her down as quickly as possible. Shun yelped as her sister’s advances bent her backwards, forcing her back against the floor as she was gulped down up to her tits with barely any effort at all.

“Mmmgff?! Unnnghhh! Mfff!!” Kokona’s rampage hit a roadblock with two very large mounds that weren’t going to be claimed without a fight. Her jaw ached and cracked as she tried to open wide enough to cram them inside, but they were just too big to gulp down like the rest of big sissy. Shun’s fear vanished as a smug smile flashed across her face, her fear of ending up as a footnote on Kokona’s growing body replaced with amusement of the little girl having bigger eyes than her stomach could handle.

“Aww, what’s wrong, Kokona-chan? I thought you were going to eat me whole? There there, it’s okay, we all bite off more than we can chew sometimes, ufufufu~” Shun’s shoves and hair pulling shifted into gentle headpats and hair strokes, something that pissed the young girl off more than it had any right to. She bared her fangs and hissed in anger, redoubling her swallowing efforts to no success. No matter how wide she seemed to stretch her maw, it seemed she had reached her limit. Was this as far as she went? Was she truly too young and small to be eating a girl the size of her big sister? No, she wasn’t going to accept that! With her eyes in an angry haze, she started chomping the tits rapidly, tenderizing and chewing them as if she were an animal about to die of starvation.

“Oh Kokona, it’s no use! Though I have to admit… that does feel rather good~”

Shun relaxed herself, leaning back and placing her hands behind her head as if she were sprawled out on the beach. No, this was more like she was getting a first class full body massage for free, courtesy of her jealous little sister. She closed her eyes and smiled, her lower half curled up and stretching out the stomach of her half-pint sibling, completely convinced she could now escape this situation whenever she pleased. She just ignored the tingling of her legs and feet from the dripping stomach acids in Kokona’s gut, that was of no concern to her. She could always take a bath to wash off any slime later… but that was when she felt herself suddenly begin to slide downwards.

“H-Huh? What’s happening? K-Kokona?!” She felt the biting suddenly reach her nipples, which instantly activated her erogenous zones! How on Kivotos had she advanced enough to reach them?! The flustered lady tried to reach down to start shoving her sibling off again, but then her teeth gnashed just right against a particularly sensitive spot, and an embarrassing moan suddenly uttered out from deep within the sexually repressed woman!

“O-ohhhhhhHHHHH!! No, Kokona, stop!! You can’t chew right theeeeeeere!” Her body turned into jelly, as pleasure coursed throughout her entire form. That infuriating tongue and those insufferable teeth worked together to make her holler like no man ever could, reducing her to a woman that could offer her attacker no further resistance. She didn’t even realize Kokona had already crammed her breasts into her gullet and past her collarbone, meaning all she had left to consume was her head and arms. She lay limp in her lips, panting and drooling as wave after wave of pleasure rippled through her very core.

“Kokona-chan, p-please… Let your big sister g-go…” Kokona’s lips curled as the pathetic heap of a woman begged and pleaded to be released. There was no way in heck she was letting her go after she made a fool out of herself like that! Depraved women like her were better off being eaten and transformed into breasts on a real lady for men like Sensei to enjoy! And that was exactly what she was going to do~ Offering her sissy no opportunity to say goodbye, Kokona merely opened wide, and started slurping down the rest of her, one wet glurrck at a time.

“Nooooo, stooooop… d-dooommphhhff…” Shun’s hands twitched outside of Kokona’s lips as her arms slid down alongside her sister’s halo, leaving ten delectable fingers to slurp and slather with her drooling embrace. The silver-haired girl committed her big sister’s unforgettable flavor to memory as the last of her slunked inside with a wet slup, the bulge of her hands vanishing down her throat and settling with the rest of her inside her tummy with a gravid slosh. Kokona licked her lips clean and grinned, marveling at the sight of her black dress somehow remaining intact with her tasty sister crammed inside.

“Ehehe, not so big now are you, sister? You’re just a bump in my middle, waiting to be melted down into so much chest meat~” She taunted, smacking the sides of the meaty swell as it rocked back and forth inside her taut middle, the older sister trying her best to catch her bearings in the impossibly tight confines of an eleven year old. Shun’s voice rang out as she whined and complained, her words muffled by the layers of organs and flesh between them. Kokona wouldn’t have paid much attention to her if she could, however, as the words of those who have already been eaten are worth about as much as a pig that’s about to be sent to the slaughterhouse.

“Welp, time to go back to class, big sister~ I’ve got to explain to all the kids how I swallowed you whole! Ahh, I do hope everyone understands that you’re better off inside of me than out, I’m sure they’ll get it once you’re busy filling my bra out~” Kokona hefted herself off the ground with some effort, her belly extra heavy with 100+ lbs of fresh meat weighing her down. She had to use her arms to support her belly, her legs shaking dangerously with each and every laborious step towards the exit to the back room back into the main class. Her mind wandered as Shun tried to shout over the loud churns and stomach grumbles, her voice little more than a memory to file away with the rest of her soon to be digested sibling.

“Ehehe~ With sis padding me out, surely Sensei will finally take note of my adult charms~” Kokona pictured an older and more graceful version of herself post digestion, her usual black dress stretched to the max with all that remains of the slushed Shun. She imagined her boobs bouncing and swaying with every little movement, not unlike how her own sister’s titty meat did from the slightest breeze. That made her think… maybe Shun had eaten someone to get that curvy, too? Wait a sec, what if she was who Kisaki was talking about eating other students to begin with?! Had she just triumphed over a seasoned predator, putting her in her place underneath her shirt where she belonged?!

“I told you not to underestimate me, sis. You can make it up to me by being the biggest, bounciest boobs to make Sensei fall in love with me, ehehe~” Kokona waddled out of the room, the sounds of steady digestion now completely overtaking the feeble whimpering of her defeated elder sister. She couldn’t wait to churn this hag and get the breasts she always deserved, along with the recognition of everyone in Shanhaijing Secondary School as a fearful predator. Maybe she’d go find Kisaki and rub it in to her, too. If nothing else, she could chomp her down as well, should she neglect to show her the respect she deserved. She might not give her as much boob fat as Shun, but another patch of flab on top of sissy never hurts, right?
