Misaka Mikoto, the 3rd ranked level 5 and her best friend Kuroko Shirai walked down the hall next to each other. Both in their school uniforms that include a white shirt, a light brown vest and a plaid skirt. Misaka had brown hair that went down her neck but it wasn't too long while Kuroko had light red hair in pigtails.
 "Ugh school was a drag today" said Misaka
 "It was but the thought of you kept me going" said Kuroko
 Misaka sighed at Kuroko's usual antics as they arrived at their dorm. Misaka was very worn out so she jumped straight into her bed but quickly just sat up against the wall hugging her big stuffed animal. Kuroko sighed at her crushes childish things but today she had a little trick up her sleeve. Misaka's mind wandered around and the thought of Toma came to mind but she quickly went red and shook her head to get rid of it. But because of that her attention was focused elsewhere giving Kuroko the perfect chance. Kuroko quickly teleported and lunged at Misaka who was still not paying attention.
 "Onee Samaaa" yelled Kuroko
 Misaka looked up as Kuroko was only a few feet away. Instead of immediately shocking her, Misaka tried to tell her to stop but as she tried to speak Kuroko's head went straight for her gaping mouth. Misaka felt her lips part with Kuroko's entire head sliding into her mouth. Misaka's cheeks were puffed out and it felt weird so Misaka quickly did what anyone would do if something was in your mouth.
*gulp...gulp*
Instead of trying to spit Kuroko out, Misaka swallowed instead letting the large head go into her throat. Misaka could hear Kuroko but it was muffled so she couldn't really understand. Misaka swallowed again and her lips came around Kuroko's small frame and at this point Misaka was trying to hold Kuroko down since she was struggling so much. Kuroko was trying to teleport but for some reason it wasn't working. Perhaps it was Misaka's saliva but Kuroko didn't understand at all. The only thing she knew was Misaka's gullet was pulling her further and the stench of Misaka's stomach was getting closer. Misaka felt Kuroko's small chest enter her mouth and got embarrassed almost immediately. Kuroko on the other hand moaned and the thought of Misaka's tongue touching her breast was a dream come true
*gulp*
Two lumps traveled down Misaka's throat as next was Kuroko's flat skinny belly. Kuroko's head slid inside of Misaka's stomach and the walls pushed out for it. The smell was awful and stomach acid was already touching Kuroko and not to mention it was tight. Misaka felt as her belly filled up and was starting to grow. Misaka swallowed up Kuroko's belly and ate up her hips. Kuroko's crotch slid across Misaka's tongue making her moan once again. Misaka tilted her head back and let Kuroko's skinny legs slide into her gullet. Misaka took off Kuroko's shoes and felt her feet go inside. Misaka closed her over Kuroko's feet and a single swallow ended her meal. Misaka took a deep breath and felt the last of Kuroko go down her gullet and eventually into her stomach. Misaka's belly was huge and the outline of a curled up Kuroko bulged from it. Misaka felt her belly and rubbed it a little but didn't understand how she could actually eat Kuroko whole.
 "Um Kuroko could you please teleport out of my belly this feels weird" said Misaka
 "I can't it's not working" said Kuroko
 Misaka still couldn't understand Kuroko so Misaka tried to throw her up but that wasn't working either.
*gurgle*
Misaka wasn't really sure what to do but her eyes wanted to shut.
 "Kuroko you're going to have to spend the night inside my stomach and tomorrow we will go to the hospital and get you out" said Misaka
 With that Misaka put her head back and held onto her stuffed animal and fell asleep. Kuroko was in awe that Misaka really went to sleep and left her inside the stomach. Kuroko growled and pushed against the stomach walls. Kuroko wasn't sure if it was even possible to survive that long inside of the wet sack. Her assumption was right though as Misaka's stomach went right ahead and was starting its digestion overhaul. The green liquid was pooling up under Kuroko and dripped from the walls getting all over Kuroko's school outfit. Her school outfit was ruined as holes were appearing all over it showing her bare skin off.
 "I really need to figure a way out since her stomach isn't going to let me stay for to long" muttered Kuroko
 Kuroko tried to teleport again but that didn't work, still leaving her to try and make Misaka throw up. Kuroko has trained with Judgement so she knew how to fight but her skills inside of Misaka's belly were very limited. With the walls hugging her body Kuroko could only really swiftly punch with no power or push the walls out of her way. Kuroko didn't give up though as she just kept going at it until her entire body was exposed and her clothes were melted away mixed in with the acid coming for her. Kuroko felt as her body was softening and her stamina was wasting away. She stopped her struggle and hugged her knees hoping Misaka would wake up before it was too late.
*blorp...churn*
Sadly for Kuroko though Misaka was in a food coma and she wasn't going to be moving around until Kuroko was sliding through her bowels. Misaka snored almost as loud as her belly churned which filled the room. Kuroko's form wasn't as much of a clear outline as before but if someone saw her belly they could clearly see it was a person.
*glorp... glop*
Kuroko felt the acid pass her belly button and at this point she wasn't sure how long shes been inside the hot chamber. Kuroko only could feel some of her body as the parts she couldn't feel were melting away and adding the slurry under her. Kuroko's skin was red and melting off and soon she's had enough.
 "MISAKA PLEASE WAKE UP I DON'T WANT TO BE DIGESTED HURRY AND GET ME OUT" screamed Kuroko as she went into another fit of struggling
 Misaka didn't hear a thing and her belly moved a lot while groaning loudly muffling Kuroko even more than she already was. Kuroko felt her eyes getting heavy as the acid reached her small breasts.
 "Onee sama...I'm...not...food" muttered Kuroko
 *groooannn*
With that Kuroko shut her eyes and fell into a digestive rest. Kuroko's body went soft and the walls crushed down on her, breaking her bones and killing Kuroko in one foul swoop. The acid melted her flesh and insides to a mere unrecognizable slurry of digested meat while her bones floated around. Kuroko's form left Misaka's belly leaving only some soft spots and bones including Kuroko's skull pushing against her stomach walls.
*slosh...crack*
Kuroko's bones melted to nothing or at least the small ones did as the bigger ones just got smaller over time. After a few hours of digestion Misaka's belly rounded out and was filled with a sloshy digested Kuroko. Misaka's soft belly could be used as a pillow but no one was there to cuddle with her.
*groan*
The stomach was finished with Kuroko and her remains flooded into Misaka's intestines. Her stomach drained everything out and it was as if Kuroko was never there. The mushy remains made their way through Misaka giving nutrients and adding fat to her body and eventually turned into shit waiting in her anus. Opening her eyes finally Misaka stretched out and went to the s
bathroom like nothing happened. It wasn't until she saw herself in the mirror that she stopped.
 "What the fuck I'm bigger" said Misaka
 Indeed she was as Misaka now was sporting double d tits pushing against her school uniform. Misaka noticed her bra actually snapped and was only hanging on because it was pressed against her shirt. Misaka then turned around and her face reddened as her skirt didn't fit but luckily the shorts she wore hid her bare ass but it was still round and thick to wear it pushed the limits of her shorts. Even her thighs were thick but she didn't know why. Misaka looked at her pudgy belly and poked and then everything came to her.
 "Did I actually digest Kuroko" said Misaka
 *flwarrpp*
Misaka farted and needed to know for sure. If Kuroko was still whole Misaka didn't want her in the toilet so Misaka went to the shower and slipped her skirt and shorts off and squatted down.
 "Please be okay Kuroko" said Misaka
 Misaka's hopes were destroyed instantly as she felt the slimy log of a turd come out of her anus instead of Kuroko. The log plopped on the shower floor and more of the digested brown slush of Kuroko flooded out of Misaka. Undigested bone and red hair filled the logs of scat as they piled up slowly.
*plop...thud*
Misaka's anus opened wider and wider with each log as they got thicker and were riddled with specs of bone.
 "Kuroko is really just my poop that's a lot to take in" said Misaka as shit kept shitting
 Kuroko's skull plopped onto the pile and was buried by several logs of shit and was nowhere to be seen.
*splat...plop plop*
After 15 minutes of expelling all of the scat from her anus Misaka waddled over to the toilet paper and wiped up the mess on her ass and flushed the paper in the toilet. She looked at the mass of shit before her that used to be her friend and felt horrible for digesting her. But Misaka did appreciate the improvements on her body and wondered if Toma would ask her out now that she was thick.
 "Well I have to get to class Kuroko I'll get a shovel and a bag when I come back and pick you up though and bring you to the frog doctor and maybe get you revived" said Misaka
 But that was only Misaka being optimistic as Kuroko was going to be nothing but Misaka's poop forever.
