The Sakura Empire was filled with loss and dread as they ended up losing the Black Mental Cube from the Azur Lane. Sitting on a cruiser was Takao, a heavy cruiser girl with long black hair in a ponytail and wore a white admiral outfit that tightly wrapped around her curvy sext body. Takao was a bit depressed about the whole thing blaming herself for it all as she thought of what she could have done better. Takao sighed and hung her head down now looking at the dull floor.
 "Now what" said Takao
 Behind Takao was her older sister Atago, a girl wearing the same outfit with a bit thicker of a build, long flowing black hair and a set of cute wolf ears matching the color of her hair. Atago could see Takao was a bit depressed but it was an older sister's duty to mess with their younger siblings even in desperate times. Atago silently steps behind her sister before crouching down and hugging her sister from behind. Takao yelped feeling a pair of hands grab onto her jugs and squeeze them around. Takao looks back seeing her sister's goofy smile. Takao groaned and pushed her sister away, annoyed with her. Atago pointed and laughed at Takao, finding her reactions always the funniest. Takao though was just mad and could not believe Atago was doing something so childish at times like this. 
 "Oh c'mon show me that cute smile" said Atago
 Takao grit her teeth as she started to think about when they were looking for the cube. Back then Atago was also groping all over her and messing around. Takao was pissed off at having such a useless sister and wondered how she could make use of her. Then finally a fantastic idea came to mind that even Atago could do. Atago was pointing and laughing at Takao hysterically as both hands of Takao grabbed her waist and pulled her close. Atago and Takao's breasts pushed together as they were face to face and Takao had a smile on her face. Atago didn't like what was happening since Takao never does stuff like this so she got nervous. Atago squirmed to free herself from Takao's grasp and she looked up to see the wide mouth of her sister. Atago's wolf ears went down and she screamed. Takao pulled Atago forward, placing the top of her forehead on her tongue. Atago cringed and squirmed as her head was pushed further inside. Atago was muffled by the mouth and Takao's throat started to bulge out.
 "Takao wait stop I'll be useful just spit me out" said Atago
 Atago pushed her sister back but it didn't do anything as another loud gulp sounded bringing her further down the gullet. Atago whined as her body was groped, feeling hands on her ass squeezing and caressing her ass cheeks. A groan came from the stomach pit and Atago's eyes widened. She screamed terrified out of her mind while her sister ignored her pleas and continued on. Takao swallowed the slim shoulders and grabbed onto her sister's sexy thick ass and pushed on it while gulping. Doing so aided in pushing the giant tits her sister had into her mouth and she played around the flesh melons before opening her throat and swallowing them down. The nice round orbs pushed out the throat and Takao cringed a little and swallowed hard, getting the big breasts all the way down. 
 "Please stop its weird and smells bad...this is scary" cried Atago
 Atago continued to beg and plead for her sister to let her out but soon enough she found the stomach. Her cheek squished against her face as she was squeezed into the tight sack. Takao kept pushing her sister in as she reached the hips and lifted her up letting the lower half hang out in the air. Takao's belly grew larger with each gulp and the screaming face of her sister bulged looking terrified.
 "It's not too late just spit me out this isnt funny" cried Atago
 Takao smirked and pushed the ass down her gully and slurped her older sister's yummy legs in and took the white shoes off and wrapped her tongue around the feet before pulling the last bit down. Takao's mouth closed and she held her throat with her fingers and gulped the feet and traced them all the way down to her stomach. A big gut bulged out from under Takao's admiral coat with the vague form of her sister curled up inside. Atago cried and squirmed, feeling the tight stomach all around her grabbing onto her body and not letting her move much at all.
 "Please Takao puke me up this is weird and uncomfortable" pleaded Atago
 Takao licked her lips and rubbed her large belly enjoying the stuffed feeling. Her sister now was just food but Atago seemed to not get it yet.
 "Atago I've been sick and tired of you acting like a fool on such important missions so I took the initiative to make you more useful as fat on my body instead" said Takao
 The only response Takao got was a crying apology from Atago saying she will do better and be serious. Of course Takao had already made up her mind to digest Atago.
 "Well just shush up and digest I have work to do but I can't have you hanging around still alive" said Takao 
 Takao looked around and dipped into her private quarters so she could be left alone and process her sister in peace. Takao sat on the bed holding her large tummy with a satisfied smile on her face and started to rub it. Atago cried and begged to be let out, feeling the green acid spreading across her body ripping her white outfit to shreds. Her body burned terribly as digestion took full hold of Atago.
 "Please Takao it hurts so much...I beg of you let me out" cried Atago
 Takao was enjoying all the squirming in her gut which made her feel horny. She couldn't help but touch herself even with her pants off just rubbing her wet crotch. The pants had a little wet stain from all the pussy juices and Takao moaned. 
 "Shut up Atago..I'm trying to masturbate to your squirming" said Takao
 Atago cried hearing her sister say such a cruel thing as she felt like it was on fire. Her skin turned a little red as digestion went on. Takao rubbed her pussy moaning and grabbing at her tit letting her stomach slosh and sway around. Atago's face and hand imprints appeared on her belly multiple times making her moan and enjoy it even more.
*bwaarrrpppp*
Takao belched and her stomach tightened and let out some of the air Atago was breathing. Atago panted in an even more uncomfortable position and the first two hours came and went. 
*blurgle..churn..glorp..glop*
Takao's crotch was super wet with juices and cum from orgasms and the gut lost a bit of shape. Atago was on the brink of death as her soft body could barely take on much more pressure.
 "Sis..please..I'm..still..here" muttered Atago
 "You're almost dead just give up and melt into my body already" moaned Takao as she orgasmed for the fifth time
 Takao twitched a bit and went limp as her belly groaned and started to break the soft girl up. Atago saw the acids reach her chin and her eyes shut and a bone broke. A final scream came from within but it sounded like there was water or something in Atago's mouth. It only lasted about thirty seconds as the moving and screaming died out with Atago. 
*slosh..crunch..blorp..churn*
Atago lost her form as she was crushed down, losing her shape. Her bones were being crushed and the meat just slid off the bones and mixed together into a big mix of soup. Takao moaned and pressed her hand into her squishy gut breaking some bones and watched her sister's rib cage and skull bulge against the stomach walls.
 "Look at you now..so close to actually being useful" said Takao
 The stomach churned away at the soupy remains for another hour before pushing whatever remained through Takao's guts. Takao moaned, pressing her shrinking belly down, feeling her mushed up sister going through her guts. Takao blushed and felt all her assets being thickened up. Her tits got huge and ended up snapping the buttons of her admiral uniform and burst out jiggling a lot. Her thighs and ass stretched her pants out quite a bit but they were able to still stay confined within the white pants. Takao breathed out and grabbed her bare tits and smiled before sliding her hands down squeezing her thighs.
 "There now you can be useful this way not a complete drag and hold everyone back" said Takao
 Takao giggled, shaking her big booty making the cheeks clap as the need to shit came. She smiled and slid her pants down with her panties before squatting over her sister's bed who slept next to her. With one hand on her ass cheek and the other rubbing her pussy Takao squeezed and moaned feeling the massive smooth bone filled turds start to exit her rear end. The long dark brown shit plopped on the bed slowly making a smelly pile. Takao moaned and aggressively rubbed her clit as her legs shook, feeling a massive amount of pleasure. Her sister turned into a bunch of logs filled with hair and bones. The black flowing hair many people admired now were in small clumps or separate strands sticking out of giant turds. The lovely body of Atago turned into scat within a few hours. All those thoughts ran through Takao's head as she shit.
*plop..plop..thud..splat*
With the combination of an amazing shit and fat on her body Takao was so happy she put Takao to use. The white admiral outfit completely stained brown not a single spec of white left pushed out with turds bursting from the holes of the torn uniform. Takao moaned and orgasmed again on the pile before pushing the skull of her sister out and finishing her giant shit. Takao used the clean part of Atago's blanket and wiped her ass clean before pulling her pants and panties up. She turned and looked at the mess she created of her sister's remains and no feeling of sorrow or regret filled her. Takao felt her tits and ass thinking Atago will be much better on her body thinking she could pull a husband and become a sexy wife. Takao left the remains on the bed and would let the janitor deal with it.
