Momo Yaoyorozu was walking down the hall of UA high. The tall, curvy girl with big black hair and wearing her school uniform was on her way to see Mei Hatsume. Momo arrived at the engineering room where Mei always hangs out and makes things. "She said she had something for me…I wonder what it is?" Thought Momo. Momo went to knock, but a sudden explosion caused Momo to fall on her back. A large body fell on her and Momo was thrusted between Mei's giant tits. "Haha! Another failure! Oh hi Momo! I have the item ready!" Said Mei. Mei hopped off Momo and walked back into the room. Momo sighed and followed in, seeing a giant pile of projects Mei had. Mei grabbed something off her counter and turned to hand it over. "This is a pretty cool one…a mask with a portal inside that's connected to this rig here!" Explained Mei. Momo was handed the mask and it looked like a plain black cloth mask she would wear if she were sick. Mei booted the machine up and Momo's eyes grew seeing a portal form in the mask and she could see Mei. "See!?! Isn't it awesome! If you wear this during training or in a battle, someone can fill your body with nutrients safe away from the fight!" Said Explained Mei.
  Momo was amazed and she smiled at Mei. "This is fantastic…I have a three hour training block later today! Let's try it out then!" Said Momo. Mei just laughed and brought Momo to an oven she keeps on hand. "I already knew that, I have a full turkey cooking as well speak! It'll be done when the training starts, so just put the mask on and keep your mouth open. I'll cram it down!" Said Mei. Momo hugged Mei and left in a hurry, excited for today's training. A couple hours passed and it was time to train. Momo went to a more secluded area, not wanting to show her mask off yet. Momo was dressed in her skimpy hero outfit and had the mask in hand. Momo placed it on her face and opened her mouth up. Momo started to use her quirk and rapidly made small dolls, patiently waiting for Mei. 
 DING
 Back at Mei's area, the turkey finished up and was ready to be handed off. Mei opened up the oven and placed the turkey on the counter. "Okay, I'll season and get this ready for Momo!" Said Mei. Mei was wearing her black tank top and baggy tan pants, with no shoes on. Mei looked at the portal and could see Momo's whole mouth. The red, shining flesh with saliva dripping from the roof. A slimy, wiggling tongue awaiting for some delicious meat. 
  Mei turned around and walked right in front of the portal. The seasoning was nearby, but Mei didn't account for one of her many inventions to have fallen on the ground again. Mei stepped on it and slipped backwards. Mei yelped, but unfortunately for her she fell back into the portal. Mei's thick, round booty fell right inside of Momo's mouth. Mei sat there, feeling a warm moist breath hit her ass. "Oops…sorry Momo! Let me just…kya!" Yelped Mei. Momo had swallowed on the other side, causing Mei's ass to slide inside the tight throat. Mei tried to pull herself out, but the slick throat was holding onto her ass like. "WAIT MOMO!! STOP THAT'S NOT THE TURKEY!!" Yelled Mei. Unfortunately, no sound came through the portal so Mei didn't hear the gulping and Momo didn't hear the screaming. On Momo's side, she felt something big and meaty enter her maw. The round object didn't taste like turkey, but Momo swallowed anyway and didn't question how Mei prepared the food. 
 GGGGUUUULL UUULLLLLPPPP
 Momo gulped hard, feeling her throat expanding. "Hm? That's weird…this turkey is bigger than before. And it's moving? Mei must be making it wiggle…I'll just keep swallowing." Thought Momo. Momo had to use the sheer force of her throat to get this giant bird down.
  Mei felt her thighs sliding inside the slimy maw. Momo's tongue was trying to explore her curves, but it wasn't very satisfying. Mei had a hand on the counter and was putting all her muscle into trying to escape. "She can't hear me!! I need to get out before she swallows me whole!! Who knows how strong her stomach is!" Yelled Mei. The gullet grabbed her and dragged her entire ass inside the gullet. The tight feeling of keeping Mei contained made the pink-haired girl groan in pain. Mei's legs were forced in the air as she was folded up like a sandwich. Mei hasn't never been in such a position as she wasn't very flexible. Mei felt like she was going to snap in half at any second. "Someone!! Help me!! I'm stuck!!" Yelled Mei. The strong pull caused Mei's thighs to disappear inside the dark gullet. Momo's throat was much stronger and stretchier than Mei had ever anticipated. The slimy feeling crawling up Mei's back made her shiver. It was warm, with sticky goop slathering her skin. The clothing on her body was plastered to her skin, keeping some bits dryer than others. A gulp dragged Mei down, causing her ass to pop inside an opening. She had reached Momo's stomach and was starting to fill it up. 
  Mei wiggled and squirmed, but as her knees crushed her giant chest, Mei was feeling exhausted. Momo on the other hand was getting tired from swallowing. Sweat was running down her cheeks and forehead. Her bare belly was bloated out with a fat ass bulge. The two melon shaped ass cheeks continued to bloat Momo, but the naive hero in training still didn't put it together.
 UUUUULLLLLPPP GUUUULLLLPPP
 Momo had both her hands holding her growing stomach, with pained groans escaping her lips. The feeling of having such an oversized belly was new to Momo. It hurt, but she didn't hate it at all. "Did she cook more!? This is ridiculous…it just keeps coming…why is it moving so much!?!" Thought Momo. Momo's throat expanded, with two giant tit lumps pushing it out. Mei's chest was crushed inside of Momo's throat, with the two melons complete with two nipple bulges having joined inside Momo's body. Momo gulped, feeling more of this utterly giant meal fill her belly. Momo closed her eyes, doing her best to keep it all down.
 UUUULLLPP GGRRRLLKK SLRRRPP
 The giant mounds in her throat slid down and Momo felt something new enter her mouth. "I-is this hair!?! Wait…what am I swallowing!?!" Thought Momo.
  MMMMMPPPHHHHHH
 Momo heard the voice of Mei and a few fingers touching her lips. Momo realized what was happening, but she couldn't regurgitate her. Momo closed her eyes and kept gulping. 
 GGGGUUUUULLLPP GGGGLLRRRKKK
 Mei's head slid inside of her throat, with the distressed face making a thick imprint. Mei's hands and feet sat inside of Momo's mouth, wiggling around on top of her tongue. Momo closed her mouth and finished the support student off. 
 UUUUUUULLLLLLLLLPPPPPP
 Mei's face, feet and hands all slid down the slimy gullet, joining the rest of her body inside Momo's stomach. Momo opened her eyes, with a few tears having welled up. Momo tore the mask off her face, letting her pink tongue flop out of her mouth. Saliva dripped off the pointed tip, plopping on Mei's screaming face bulge. Momo huffed, having devoured such a giant slab of meat. She was utterly stuffed and didn't want to move. "Mei…I'm so sorry…I'll get you out." Huffed Momo. Momo looked down, seeing her sweat-slathered belly. Momo blushed, seeing Mei's curled up form. Her terrified face, giant tits, curled legs and fat butt all made luscious imprints. The sight turned Momo on a little.
  Momo stroked Mei's head, finding the bulge very hot. The internal belly rub of Mei's squirming made Momo's face burn hot as her crotch got wet. The red panties she had on were getting soaked. A dark stain formed, with visible drips of pussy juices dripping down. A rumble sounded and Momo's stomach squeezed around Mei. The engineer yelped as she was stuffed in a tighter ball. Air was forced up Momo's gullet and entered her mouth, puffing her cheeks out.
 BBBBBWWWWAARRRRRRRPPPPP
 Momo let out a monstrous belch, sending thick globs of saliva all over her belly and the green grass. Momo sighed in relief, before a cruel thought came to mind. "What if…I digest her instead?" Thought Momo. Momo gulped some saliva and stared at her fat belly.
 GUUURRGGL GLOOORPP MMMMPPH
 Momo wasn't sure why, but the sounds of her stomach gurgling drowning Mei's muffled pleas out was super hot. Momo bit her lower lip and narrowed her eyes. Momo gave her belly some soft slaps, before speaking. "Actually Mei…I think I'll just go ahead and digest you. No one saw me swallow you…this might be a breakthrough for my quirk…and I can't help but love how full I feel~♡." Moaned Momo. Mei's face stretched the pale gut out, with her gaping maw and sunken eyes staring right at Momo.
  "WHAT!?! DIGEST ME!?! I'LL DIE!!! PLEASE DON'T DO THIS!!! THIS IS SO GROSS!!" Screamed Mei. Mei felt a hand land on her face, before shoving her back. The stomach squelched and Mei's heart sank as Momo decided her fate. Mei huffed and looked around the horrible oven. The red walls were covered in acid as it ran down and dripped on her body. It slightly burned, irritating Mei's ski. Mei cringed and kept fighting. The walls stretched and the acid sloshed. "GAAAHH!! SOMEONE HELP ME!!! MOMO'S GONE CRAZY!!" Screamed Mei. Mei pounded on the walls, splashing acid on her face and tits. The acid was eating through her clothes, exposing bits of her hidden skin. The soaked tank top slid off her body, showing off her bare melons. As Mei squirmed, she felt the acid starting to burn more. It started to really hurt, causing tears to swell in her eyes. "KYYAAA!!! OH GOD IT BURNS!! I'M MELTING!!! HEEEELLLPPP!!!!" Screamed Mei. Mei was stripped of her clothing, with it sinking under the acid since they were so soaked. Red blotches appeared all over her, with the flesh looking much softer. Momo's ultra strong gut wasn't playing around and Mei was just some new meat for it to grind down and break into nutrients.
  Mei fought, but as she looked down at the steaming liquid; she further lost hope. The bubbling liquid had overtaken her round booty and was crawling up her legs and back swiftly. It was still clear, and Mei could see her butt getting softer under the steaming acid. The burning sensation was only getting worse, making Mei wildly thrash and beg. "MOMO!!! IT HURT SO MUCH!!! PLEASE!!! I'LL EVEN STUFF MORE PEOPLE INSIDE YOU!! JUST SPARE ME!!" Begged Mei. On the outside, Momo had plopped her rear on the ground and both legs on the sides of her belly. Her plump thighs held onto her churning cauldron, while a hand was under her belly. "Hhhaahhh~♡♡!! Keep squirming Mei!! I want to feel you move until my stomach destroys you!!" Moaned Momo. Momo had stuffed a hand into her panties and was touching herself. Momo was so happy she wanted to train by herself and away from others. 
 MMMMMPPHHH GLOOOOORRRPPP
 Momo could hear Mei screaming her head off, but Momo ignored her. The only thing she was concerned about currently was cumming. Sweat beads ran down her belly, going over Mei's softening curves. Ten minutes had passed by and Mei was already looking less human. The curves were rounding out, with globs of meat being torn off her pristine bones.
  "Mmmmmm fuck!! Your body is so weak!! I could break you whenever I want~♡!!" Moaned Momo.
 GGGWRRRLLPP GUUURRRGGGLLLL
 Momo rubbed her flooding cunt faster and faster, hearing the sounds of her squelching pussy as she flooded her panties. A puddle of juices and sweat had formed under Momo, pooling around her ass and belly. Momo reached over, gripping Mei's booty bulge. Momo shuddered, feeling Mei's ass melting right in her hand. The flesh was breaking apart and Momo could just squeeze and feel Mei's pelvis. "So soft…so meaty!! Why have I never tried this be-HHWWAARRRPP!!" Said Momo, belching Mei's pants up. The acid soaked clothing was torn to shreds and Momo just imagined what Mei's body looked like. Momo squeezed as hard as she could, completely smashing Mei's ass into a formless lump. The booty meat was just sloshing goop now. Momo pushed herself up and landed on her belly. Mei was crushed into the ground and Momo started to hump the bulge.
 CRRUNNCHH KRRCCK CCCRRRKKK
 Mei's feeble body couldn't take all the added pressure. The sound of soft bones snapping filled the air, adding to the symphony of noise. Momo's face had contorted into an ahegao, with her eyes rolled back and tongue wagging out like a dog. A large cum stain was plastered where Mei's ass used to be.
  Mei was a mess inside of Momo, with her body broken and melted. The acid sloshed at her giant tits, with her boob meat starting to become mush and add to the bubbling goop. Most of Mei's nerves had melted away, relieving her of some pain, but not all of it. Mei was in tears, feeling her face slowly melting off her skull. "Momo why…why did you decide to digest me!? I don't understand…I'm a person…not food!" Cried Mei. The brute force of Momo's humping had crushed her pelvis to small pieces. That event had caused Mei to be torn in half. Her lower end had suffered most of the damage, with her legs completely mangled and broken into small bits. Mei felt weak and tired, watching as her innards floated up. The acid was melting her from the inside out and death was looming over. Mei's left cheek slid off, showing some of her skull. Mei didn't want to die, but it was very apparent she wasn't leaving Momo's gut alive. "You'll be…charged…this is murder…they'll…throw you in prison." Muttered Mei. Of course, Momo didn't hear a word and kept humping her mangled bulge. Mei just sat there, crying as both arms eventually snapped in half and fell over her body. Mei was basically just a stub, with her own melted body bubbling under her chin. "No…I can't….die." Muttered Mei.
  PLAP PLAP GOORRGG PLAP PLAP
 Momo's slimy cunt kept banging into her gut. Momo's ass and tits jiggled with each movement and her gut loudly sloshed with each bang. Momo looked down, seeing Mei's half-melted face stretching the top of her gut out. Momo stroked both Mei's face and the side of her gut. "Oh Mei~♡♡!!! It's almost over…I'm…I'm going to cum!!" Moaned Momo. Momo went faster and Mei let out a final screech.
 CRRUUNNNCHH SLOORSSSSHHH
 Momo squirted, letting out a large amount of cum. She twitched and flopped on her belly. Momo huffed, twirling a finger over Mei's still face. The last thrust had snapped the girl's neck, finally killing her. "Hehe…I actually killed you…what a strong belly I have~♡." Moaned Momo. The sounds of Momo's stomach gurgling away at Mei's corpse filled the room. Momo's ass was pointed in the air, with a puckering bulge of her asshole being visible. This new sensation had completely taken Momo over. Nothing had ever felt so good and Momo was on her way of becoming an addict.
 GLLOORSSHH SLOORSHH GUURRGL
 Momo slapped her gut, watching her flesh ripple. Mei's lump was barely human, with mostly bones bulging out now. Momo could see a skeletal arm and some of Mei's rib cage protruding out. It was a cruel and morbid sight, but Momo couldn't get enough. 
  Momo watched Mei's face melt away right in front of her eyes. The last terrified expression was gone and what replaced it was a lifeless skull. The eye sockets were sunken in and Mei's jaws were wide open. "What a final look…there's barely anything left~♡." Moaned Momo.
 GGOOORRRGGG GLOOOOORRPP
 Mei's melted corpse was all finished and ready to be pushed down. It only took a little over an hour to churn Mei into nothing. Momo's stomach pushed the goop and mass of bones into her guts. Momo could absorb something like this within a minute.
 GGGGGLLOOOOOOOORSSSHHHH
 Momo's stomach started to rapidly shrink, with her assets growing bigger. Momo's ass grew so big it pushed her skirt up. Her panties turned into a thong as the butt overwhelmed the clothing. Momo's skimpy hero outfit couldn't take the added fat, with her tits growing so big they snapped the strap and popped out. Momo was left with a round chubby belly. Mei's remains had moved down and were heading directly to Momo's bowels. Momo pushed herself off the ground, admiring her new curves. Momo grabbed both of her boobs, giving them a few squeezes. "Wow…they are so big and full…I think they are even bigger than Midnight's." Said Momo.
  Momo's admiration had to be delayed as Mei arrived at her rectum. A wet gurgle sounded and along it came a tummy ache.
 FFFFLLLWWWAARRRRRPPPPP
 Momo gripped her chubby middle, letting a blast of ass gas blow out. "Ooohhh fuck I have to shit!" Moaned Momo. Momo grabbed her panties and dug them out of her ass and dropped them to her ankles. Momo looked at the mask and smirked, grabbing it and placing her asshole right at the portal. Momo was about to shit, but the bushes suddenly cleared and an unexpected guest showed up. "Hey Momo, I wanted to ask…you….uh, what the fuck are you doing?" Asked Jiro. The punk rocker and best friend of Momo, Kyoka Jiro, had shown up at a critical moment. She was behind Momo, seeing a cloth mask stretched over and covering Momo's. "Huh!?! Jiro!?! What are yo-GAAHH!! I can't hold it!" Yelled Momo. Momo was forced to squeeze, feeling her anus open up. To Momo's dismay, she had stretched the mask and ripped it. The portal shut off and the giant log smashed into the mask. A skeletal hand bulged out and Jiro's eyes widened seeing a giant log the size of Momo's thighs coming out.
 PLLLOOOOOORRPPP SNAAAAPPP
 The string on the mask snapped and the log rapidly shot out and coiled on the grass.
  Momo was sweating and panting, unsure how to proceed. Jiro had seen it and was currently looking at the steaming mess. Jiro looked at the log of shit, seeing a snapped arm bone and several other specks. "Jiro…do I have to eat her too?" Thought Momo. Jiro ran to the front, seeing Momo's gains. Momo was sure Jiro would rat her out, but Jiro kneeled down and placed her hands on Momo's belly. "You ate someone…I don't care why or who…but that's the hottest thing I've ever seen. Let me help you dispose of them~♡." Moaned Jiro. Jiro has had hidden feelings for Momo since they met. Momo was about to let out a pained screech as she squeezed, but Jiro plopped her lips against hers. Momo and Jiro were locked in a passionate kiss. Momo Screamed inside Jiro's mouth, squeezing a giant turd out.
 PLLLLOOOORRPPP SPLLOOOOORRP
 Mei's pelvis that had shattered into pieces was coming out. The lumpy, thick log pressed the shards into her asshole, scraping it and causing Momo extra pain. Momo had grasped her monstrous butt cheeks and had them spread to the max. The log squelched and coiled on top of the first one. Mei's torn pink panties had wrapped around the log and held it together. Jiro was pushing into Momo's soft belly, feeling her hands sink into the fat.
  The extra help aided Momo, with the long second turd sliding out with both of Mei's crunched up leg bones sticking out at the end. Jiro pulled away from the kiss, letting Momo get some air. "Is this helping?" Asked Jiro. Momo nodded her head and came forward to keep kissing. Their tongues swirled around and Jiro's moans filled Momo's head.
 PLLLLOOOOORRPP SPLLOOORRPP
 The next turd broke through Momo's anus, making the new predator wince in pain. Mei's torn black tank top coiled around and was quickly buried in scat. The log smoothly slid out for about a foot, before a giant item was forcing it way out. Mei's curled up spinal cord came first and right behind was her crushed rib cage. Momo's eyes widened and tears ran down her cheeks. Her asshole was simply being torn open, making her curl her toes in pain. Rib after rib scraped her aching asshole, with her anus stretching almost as wide as her own shoulders. Momo had to pull from the kiss. "OH GOD!!! FUCK ITS MASSIVE!! MY ASSHOLE IS-MMMPPHHH!!" Yelled Momo, before Jiro muffled her. Jiro pushed all her weight into Momo's belly, forcing the turd out. It took a couple agonizing minutes, but Mei's rib cage popped out and topped the pile. Momo huffed and had to take a moment to relax her anus.
  After a moment, Momo noticed her bowels were almost empty. Only a little bit left remained, making her smile. Momo squeezed, feeling the anal chocolate sliding out. Her anus opened up, with Mei's skull coming out. Shit was smeared all over the bone. Soft, goopy shit was pouring from her barren eye sockets and missing teeth. The cute, pink hair Mei had was still attached to her dirty scalp and even her goggles were still hanging on. They were cracked, but mostly intact. "Almost…out!!" Moaned Momo. Momo popped the skull out and flopped a few slimy turds on top of it. The deed was done and Momo was empty. Momo grabbed her useless panties and wiped her anus clean of any nasty remnants. She tossed the dirty panties on top and stood up, facing Jiro. Jiro slid her jacket off and handed it over. "Here, hide your tits and ass. We can just say we found Mei like this…maybe bury your panties deep in it." Said Jiro. Momo used her boot and pushed her panties deep within the pile. Jiro and the fatter Momo headed back to report their findings, with only those two knowing what really happened.
