Mai Sakurajima rode the train to school as she was supposed to meet her boyfriends friend Rio who was a girl. Mai felt a little jealous at first as she never met this girl before and now she learned of her existence. Mai was a thin upperclassman to her boyfriend, she had long black hair and small breasts. Mai arrived at school and made her way to the science room to meet this Rio. Mai wasn't sure what to expect from this meeting but when she opened the door a sight befell her that was 100% lewd. In her chair was Rio with a picture of her boyfriend's other friend and her fingers were deep in her pussy. The look of shock was on both of their faces and Mai entered the room and quickly shut the door. Rio was an underclassman to Mai but she had a bigger chest and was only wearing a lab coat.
 "I can explain" said Rio
 Mai put her hand up as she didn't really want to hear it, she had black mail and she was gonna use it.
 "Now that I have seen this I will make you do something for me" said Mai
 Rio sighed as she was afraid this would happen
 "What is it" said Rio
 "I'm going to eat you" said Mai
 Rio was a little shocked but she guessed Mai didn't want her around her boyfriend at all now so this made sense to some degree.
*groan*
Mai's stomach groaned loudly and Rio looked at it a bit scared. Rio hasn't seen anyone else be eaten before but she heard rumors some people could do it. Rio then noted several disappearances in the area and thought maybe Mai had something to do with it.
 "By any chance all the missing people were your doing right" asked Rio
 "Nope that would actually have been my sister since I've only eaten one other person but she is a true glutton" said Mai
 Rio nodded her head but then felt the hands of Mai on the back of her shoulders. Rio didnt even notice her getting behind and now she was fear sweating. Mai massaged Rio's shoulders with a smile on her face.
 "Its okay Rio it won't hurt to much" said Mai
 That made Rio shiver and think about how Mai's acids are going to eat her body and melt her into goo. Before Rio could keep going to the part where her brown remains are laid out in some grass Mai's fleshy tunnel wrapped around her head making her cringe. Mai's lips went down and over Rio's head engulfing it fully. Mai grabbed the sleeves of Rio's lab coat and slipped it off her body leaving her nude. Mai continued down and ate her shoulders before arriving at her large bust. Mai slowly slid her hands up Rio's flat belly and then grasped her tits. The fleshy orbs spilled through her fingers as she played with them and squeezing Rio's nipples made her moan while in Mai's gullet.
*gulp*
Rio's boobs went into Mai's mouth and bulged her cheeks out. Mai giggled with a mouthful of tit and then used her tongue to lap over them making Rio moan. With a single gulp Mai got rid of her breasts and got on to the easy part with her midsection sliding down her gullet and letting her wider hips enter her maw. Mai raised Rio out of the chair and held onto her squishy thighs and lifted up. She slurped in Rio's ass and had fun slapping her cheeks with her tongue. Rio was entering Mai's stomach at this point and a small pool of acid splashed onto her. Rio whimpered as more of her body slid into the wet sack and she felt less and less of the air in the room. Mai had a hand on her ever expanding gut as she pushed down on Rio's feet and gulped her legs down before Rio's feet touched her tongue. Mai closed her mouth over them and swallowed letting all of Rio go to her gut. Rio, like a large meal, would curled up in the tight space that was given to her. The stomach gurgled around and the walls pushed up against her body making it difficult to move but not impossible. Rio was in the upside down fetal position with her forehead in the stomach acid so she made the logical decision and adjusted herself to have her head at the top.
*bwarp*
Rio's glasses came out of Mai's mouth and were covered in saliva. Mai sat in the chair Rio was in and slumped down a little letting her belly rest in her lap. It gurgled loudly filling the room with only the sounds of her stomach processing its meal. Mai hasn't felt this full in a long time and she was really loving. Rio's squirming massaged the inside of her belly making her feel amazing on the inside.
 "You are making me feel so lewd right now" moaned a blushing Mai
 Mai put her hand up her skirt and moved her panties and then started to rub her pussy. With the sounds of her stomach and Rio's squirming combined with her masturbation Mai felt as if she was in heaven. Rio heard Mai moaning and found it sad Mai was getting off to her death. Rio just curled up in a ball even more and let the stomach have her. Her skin felt softer and she didn't notice it was melting off of her. Time went on and Rio just stared into a stomach wall while she digested. Mai masturbated the entire time and she started to feel the orgasm coming.
 "Im..going...to cum!" yelled Mai
 Mai climaxed on the chair and it spilled onto the ground but it also tightened her belly. Rio yelped feeling some of her bones snap and her body being crushed. Rio heavily breathed as she was down to her last moments. The squishy walls kept coming at her and she was feeling very goopy now. It was only a matter of time before she died and melted fully into mush.
*blorp*
Rio closed her eyes and just fell asleep and the stomach went ahead and broke her limp body. Rio's flesh melted off her body and she was squished down by the stomach walls which broke every bone she had. Rio's form was completely gone from Mai's belly leaving a round orb full of mush. Mai was sweating from masturbating and decided to rub her belly. She did love how easy it was to digest someone to nothing and wondered where Rio was going to end up on her body. Mai stood up and stretched letting her belly stretch out a bit. Rio's bits sloshed around and her bones that haven't digested rattled around inside Mai's stomach. Mai held her squishy belly and pushed down on it breaking whatever was left inside.
*crunch...glorp*
All of Rio's bones broke even more leaving only tiny bones floating in the melted Rio. Mai gave her belly a quick pat and then heard it groan loudly. Rio was entering her intestines now giving her fat and other nutrients. As Mai's belly shrank Rio ended up adding to her bust size making her breasts press up against her uniform. She had some belly fat as well but Rio also made her thighs thicker and she already could imagine her boyfriend staring at her legs and wanting her to sandwich him between them. Mai sighed and walked out of the room with little evidence of what happened to Rio other than what was filling up in her bowels. Mai felt her bowels full of shit and quickly made her way to a toilet. Mai entered a stall and took her skirt then panties off. Mai sat on the toilet and immediately the first log of Rio emerged from her ass and it fell into the bowl. Logs of shit coiled in the bowl piling up under Mai as she moaned since the steamy shit that came out felt very good coming out. Rio's undigested bones were visible in the logs and Mai smiled feeling them rub against her bum. The rest of Rio plopped into the bowl with her skull mixed into a log and it filled the toilet completely leaving no way for Mai to flush her down. Mai wiped her ass clean and got dressed and left the pile of shit in the toilet for someone else to handle. Mai quickly left the building and went home to masturbate and then call her boyfriend so she could show him her new curves.
