Standing at the back of the classroom is the flat chested pink haired girl Natsuki. Natsuki is a part of the Literature Club along with her "friends" Monika, Yuri, Sayori and her secret crush MC. Currently she is having some issues due to her height. Monika, a girl with long brown hair in a ponytail that goes almost on her ankles, did a little prank on Natsuki by putting her manga on the top of a cabinet. Natsuki was looking forward to reading it all day and now she can't even reach it. Natsuki had tears in her eyes as it was so close but just right out of reach.
 "Hahaha! Oh Natsuki if only you were a little taller maybe you could reach that manga...and even MC's attention." Teased Monika
 Monika just laughed at Natsuki thinking she was just hilarious but Natsuki was tired of it. She stood there pissed while making a fist and glared daggers into Monika. Then a little smirk spread across Natsuki and she figured the club didn't need Monika. As Monika laughed while holding her gut as it ached from all the laughter Natsuki reached under her skirt and pulled her pink panties down. A little bear was on the front of the cute underwear and she threw them to the side. Monika tried catching her breath and figured it was time to help the poor short girl. The only problem was Natsuki was no longer next to the cabinet. Instead Natsuki was right in front of her which definitely shocked Monika. 
 "Oh okay let me get the manga-huh?" Said Monika confused as Natsuki grabbed her arm
 Monika was then pulled off the desk and yelped as she scraped her knees on the ground.
 "OW..Natsuki what the fu-GLOMPH-" Monika tried to speak to Natsuki was cut off
 Natsuki laid her ass onto Monika's face and moaned, rubbing her asshole all across her club mate. But Natsuki wasn't trying to pleasure her asshole and went ahead and pushed down. As Monika attempted to push Natsuki off all of sudden the tight pink asshole opened up and Monika yelped as her head was engulfed. The inside of Natsuki's ass was disgusting with the smell of shit penetrating her nostrils and the slime was covering her face. 
 "Wow...oh fuck...my asshole is stretching so much...jeez it feel soooooo good!" Moaned Natsuki
 Natsuki's tongue rolled out of her mouth as she pushed down harder letting her tight asshole expand over Monika. Her pussy was getting all wet and fluids dripped onto the floor and a little bit on Monika's thighs. Monika could barely use her arms to push the girl off and cursed her out.
 "WHAT THE FUCK IS THIS SHIT! THIS WAS NOT IN THE CODING YOU PINK HAIRED BITCH!!" Screamed Monika
 Natsuki just ignored Monika's desperate pleas and went further down pushing down on the c cup rack. The boobs were squished into the slimy tight tube and Monika gasped as it was immediately harder to breathe. Natsuki's middle was starting to expand and bloat with Monika's head pushing her guts around. A pop sound came and a few buttons came off the button up shirt Natsuki had on. 
*SLURP!!..SCHLK..SLURP!!*
Natsuki slowly slid down the skinny midsection of the struggling girl. Monika's hands moved around and tried to slap at Natsuki's ass but she felt them being pushed further down to her side. Natsuku yelped in extreme pleasure as her asshole reached the middle of Monika wrapped around the girl's hips and wrists. Monika screamed her head off feeling the tight guts grabbing and pulling her through the nasty smelling intestines. Natsuki felt the cold ground touching her ass cheeks so she picked herself up and pushed Monika's feet against the ground. Natsuki then slipped and all at once starting at the thighs the last half of Monika was slammed into the asshole making Natsuki cry out in a mix of pleasure and pain. 
 "She's gone….I got Monika fully up my ass." Said Natsuki a little surprised and impressed with herself
 Monika was sucked and pushed through Natsuki's guts until she was forced into the slimy tight stomach. Monika grunted and pouted as she was wrapped up by the fleshy walls and packed into a ball. The tight slimy flesh gave Monika very little move around so she could only weakly wriggle around. Natsuki felt stuffed as she laid on the ground patting her full moving belly. Her eyes widened feeling something coming up her throat and figured she was going to throw up. Natsuki's cheeks puffed out and no puke came.
*HHHWAARRRRPPPP*
A monstrous belch that rattled some of the desks escaped her lips and she groaned before slowly standing up. Monika screamed and squirmed around making Natsuki groan. Natsuki figured she needed to get home and started to head to the entrance of the classroom so she could leave. But as she slowly waddled over and was about to open the door someone else beat her to it. The door opened up and standing in the frame was Yuri and Sayori, two of the other members of the club. Yuri and Sayori's eyes met with Natsuki's but it only took a second for them to look down and see the big belly.
 "Um...Natsuki, what's with the moving belly that sounds like Monika?" Asked Sayori
 Natsuki had absolutely no way of talking herself out of this situation and she went with the only thing she figured would work. Natsuki first grabbed Sayori and threw her to the ground. Yuri started to blush and think the belly was cute but felt she was in a lot of danger. Natsuki then grabbed Yuri by the arms and let herself fall back. Natsuki landed ass first on Sayori making the girl yelp in pain. 
 "Are..you going to eat me?" Asked Yuri with her face completely flushed red
 Yuri didn't like Natsuki that much but the thought of being devoured by her natural enemy felt so hot to her. Natsuki could sense the pervy energy coming off Yuri and just ignored it. Natsuki unhinged her jaw and opened her mouth up as wide as she could. Yuri just breathed heavily as her face was stuffed into the warm moist mouth. Natsuki lapped her tongue over Yuri's face thoroughly enjoying the sweet taste. 
*GULP!!..GLRK!!..GULP!!*
Natsuki gulped in Yuri's head and the smiling face of the big breasted pervert imprinted her neck. Yuri wanted to be stuffed into the warm stomach of her foe and wanted to feel the warm acid bath melt her down. It just seemed so stimulating to be digested alive. Natsuki swallowed Yuri's shoulers and got a little angry as she felt the boobs press against her chin. Natsuki shoved them in making her cheeks puff out before swallowing the big tits and continued on with her thick meal.
*GLRK!!.GULP!!..GLORSH!!*
Yuri's slim middle effortlessly slid down the tight tube of Natsuki as she made her way down to Yuri's wide hips. Yuri's face was pushed through a hole where she found Monika sitting in a steamy batch of green fluids.
 "Yes..I finally arrived at the stomach!" moaned Yuri
 Natsuki lifted her prey's lower half and swallowed in the hips and butt. Yuri's face was pushed into Monika's bust as the girls were beginning to intertwine and get squished together. Monika cursed as Yuri moaned to the feeling of their wet slimy body sliding against each other. Natsuki gulped and gulped, pushing the wiggling feet down until she shut her mouth.
*GULP!!*
Yuri was all gone and the thick purple haired girl was squished up against her club member. Her pussy basically ran up into Monika's face as her own face was pushed into the bottom of the stomach. Natsuki licked her lips as her face went red and she looked down at the massive bare belly.
*BWAARRRRRPPP!!*
She belched loudly and Yuri's skirt came flying out and splat on the ground. Natsuki giggled and felt even more full. Natsuki already knew there was no way she was getting home with all this meat in her belly and decided to eat up Sayori and digest all three of them in the classroom. That entire time Sayori was being crushed under Natsuki's butt and was begging to be released. When Natsuki relieved some pressure off of Sayori, Sayori finally got a breath of fresh air. 
 "Finally I can breathe!" Yelled Sayori
 Sayoir climbed out from under Natsuki and sat there catching her breath but she didn't understand the position she was in.
 "Mmm-hhwarrrppp-one more yummy girl might make my belly explode but can't have any witnesses." Said Natsuki
 Sayori heard that and freaked out when Natsuki grabbed her from behind and pulled her forward. Natsuki didn't even let Sayori have a chance as she shoved the final girl's head into her mouth. Sayori screamed and squirmed more than Yuri did, making Natsuki a little annoyed. Natsuki gulped in the shoulders, getting a better grip on the flailing arms.
*GLORSH!!..GLRK!!..GULP!!*
Sayori cried out begging Natsuki to spare her as she felt her boobs being consumed. Natsuki was already too deep into the whole devouring girls so she just ignored the cries. Sayori's small bust pushed Natsuki's neck out and a simple gulp sent the boobs down. As the gulps sent Sayori further down she could hear Yuri moaning and Monika screaming. Sayori could feel the heat from the stomach and it was getting worse and worse. As the pink tube further expanded out for her body she was finally pushed into the stomach to find a weird sight. Monika was trying her best to keep her face away from Yuri's crotch. The reason being was Yuri had her fingers deep into her cunt fingering herself right in front of Monika. 
 "Gaahhh you gross bitch cut it out!" Yelled Monika
 "I..can't...it just feels so good!...ffuuuckk melt me into tit fat you flat chested slut!" Moaned Yuri
 Sayori was having a hard time believing Yuri was enjoying it so much as she too was being stuffed into the hot stomach. Natsuki pushed in the fat ass of Sayori and lapped her tongue under Sayori's skirt getting as much flavor as possible from the bare pale ass.
*GULP...GULP*
Down went the fat ass of Sayori and Natsuki was relieved she was almost done. Her stomach felt like it was going to explode but she was so close. The jiggly thighs slid down her gullet and with her pointer finger Natsuki pushed the feet down past her lips into her gullet and finally she closed her mouth.
*GULP*
The feet were gone and Natsuki traced the bulge down her gullet until Sayori joined the other two inside her stomach.
 "Ugh my poor-HHWAARRRPPP-belly I feel so fat...but so good at the same time!" Moaned Natsuki 
 Her gut was much bigger than her and she actually used it to shut the door. Natsuki rubbed her massive moving belly. The hands and faces of her former club mates pushed out most of them begging other than Yuri.
 "Fuck-BBBWAARRRPPP-you all just stay there melt-HWARARRRPPP-ugh I'll squeeze you all out soon enough." Groaned Natsuki
 Even though her belly ached a little she couldn't help but feel pleasure. To satisfy herself she slipped her hand under her belly and started to touch herself. A moan escaped her lips as she started masturbating. Natsuki's fingers were deep into her pussy and she smirked thinking about how she just turned three girls with promising futures into just meat in her gut. She giggled thinking it was hot and started to slap her belly to make them hurt.
 "Scream and beg for your lives you fucking useless sacks of meat-HWAAARRRPPP-I can't fucking wait to flaunt all the curves I get from you all!" Moaned Natsuki 
 "Oh yes, degrade us...please insult us more, call us names and make us feel less than human!" Moaned Yuri
 Natsuki was disgusted by Yuri and slapped the ass bulge of Yuri and got a loud moan. Natsuki wanted that bimbo to choke on her acid as soon as possible. The pain of digestion was getting worse making the girls squirm in pain but Yuri didn't stop masturbating. The acid was almost all up her head about to drown her but she refused to stop. Her jacket and shirt have been pretty much melted away leaving Yuri and really most of the girls almost naked. Yuri was approaching her climax as the acid splashed across her face. Yuri moaned and her body twitched as came. Monika was squirted in the face by femcum and cursed, feeling it get all over her. Acid flooded Yuri's mouth as her entire head was engulfed by the stomach acids and the thick girl went still. Monika was relieved that Yuri drowned and pushed the pussy away from her face. Sayori was still in shock of the pain getting worse.
 "OH GOD PLEASE NATSUKI I'M MELTING IT BURNS PLEASE!!" Screamed Sayori
 Natsuki just giggled at the desperate cries of her food as she masturbated. 
*GURGLE!!..GLORP!!..BLORP!!*
Natsuki's noisy belly was overpowering the screams of her meals. She giggled as she stabbed the ass of Yuri. Natsuki heard a snap and almost came just from hearing that but continued to hold back. The bubbly acid had reached halfway up Monika and Sayori's body. They were basically on fire and half their bodies were starting to dissolve.
 "YOU LITTLE PINK HAIRED SHIT YOU BETTER LET ME OUT RIGHT NOW OR IT'S OVER FOR YOU!!" Screamed Monika
 Natsuki moaned and squished her belly, breaking some more bones of her meals. Monika and Sayori screamed in pain from their bones snapping but didn't give up just yet.
*GLORSH!!..SLORSH!!..SNAP!!*
 Natsuki was on the verge of an orgasm. She started to hyperventilate and her toes curled. A scream of pleasure escaped her lips and she came all over her belly. Natsuki twitched a little and slowly uncovered her hand from her pussy. Cum was on her fingers so Natsuki went ahead and slurped the cum off and swallowed it. The femcum dripped down on Monika's head making her squirm a little at the gross feeling.
 "Okay you useless meat sacks...it's time for you to go!" Said Natsuki
 Monika and Sayori squirmed as Natsuki wrapped her arms and legs around the belly and squeezed. Blood curdling screams escaped the two girls' lips and finally it was over.
*SNAP!!..CRACK!!..SLORSH!!*
Natsuki crushed the pair down to the point they either passed out or died. Natsuki didn't care and simply laid backwards rubbing her still belly. The acid picked away at three still girls making them softer and less human. Their skin melted away and pretty much anything soft did as well. The belly was soon full of just mush and bones that used to be the Literature club. The stomach processed the mush before the guts opened up and happily accepted the sloshy remains. Natsuki smiled as her belly groaned and shrank down. Her flat chest started to grow and she felt her bra snap. Natsuki went from A-Cup boobs to D-Cup in one massive swoop. Her ass and thighs fattened up giving her the best curvy body someone could ask her. Natsuki was finally able to stand and immediately found a mirror in the classroom and checked herself out in the mirror.
 "Holy shit girls...you really plumped me up I bet with this body even MC won't be able to deny my advances hehe!" Said Natsuki with a massive smile on her face
 But a little rude awakening came in the form of her next bowel movement begging to come out. The half naked figured she couldn't leave the classroom since people will see her basically naked. So Natsuki went ahead and just decided the classroom was good enough. Natsuki held her fat butt and went over to the corner of the classroom and squatted down a little. Her hands grasped a fat asscheek each and she spread them open. With a little grunt and squeeze Natsuki could feel the poop rushing to come out. The anus opened and a fat turd filled with some bones plopped on the ground. Natsuki shuddered a little, feeling a sense of relief but knew there was a lot more to go. She pushed and a more solid log made its way out. A bone scraped against her asshole making her wince in pain a little but she wasn't stopping now. The steamy turd fell down and splat, making some poop hit Natsuki's ankles.
 "You pieces of shit stop fighting so much ugh!" Yelled Natsuki
 The logs seemed to be more solid and annoying as she was having trouble squeezing them out. The pile was about a foot tall with several teeth, clumps of mixed hair and even a lower jaw was sticking out. Natsuki didn't bother to pay attention to the bone remains sticking in her shit and just kept squeezing. 
*PLAP!!..PLAP!!..PLOP!!*
The wet crap fell down one by one and a sudden blockage came. Natsuki grunted and pushed hard as something large was not agreeing with her asshole. A massive turd slowly came out but the real culprit was the rib cage stuck inside it. Natsuki yelped in pain but she managed to dump the gross shit out. Natsuki happily went back to shitting the softer warm logs. Creamy crap piled up as the pile hit three feet tall. Natsuki was basically standing straight up now since the pile was so big. Natsuki had to squeeze a little harder as she started to squeeze the skulls out. One skull was missing its lower jaw and Natsuki figured it was probably Yuri.
 "Yeesh you all smell terrible!" Said Natsuki 
 Despite trying to plug her nose it did nothing to stop the smell. As the final lifeless skull fell down Natsuki smiled, shaking her jiggly ass to make sure. Natsuki grabbed some paper and wiped her ass clean before tossing the paper on the pile and turning back to see what was left of all those girls. The massive slimy heap of shit had steam coming off so many bones and clumps of hair could be seen sticking out of the brown sludge. Natsuki didn't even bother with any parting words and just looked around for some extra clothing so she didn't have to stay in the room with that horrible smell. Natsuki found a coat and waved to the smelly pile and went on her way to seduce MC.
