"Oh sissy with this you'll finally fall for me" said Kuroko pouring a liquid into Misaka Mikoto's metal water bottle
 Kuroko teleported back to her bed but as she did  some of the liquid came out of the bottle and ended up in Kuroko's glass of water. Kuroko wore her pink pajamas waiting for Misaka to come back. Kuroko was for sure this was finally going to work. Finally the door opened and a tired Misaka came through in her school uniform with the jacket on.
 "Those damn exams I couldn't even get water during them" said Misaka
 Kuroko wanted to say something about the water bottle but it would point suspicion towards her. Misaka sighed as she sat on her bed and grabbed her water bottle. Kuroko's eyes lit up as Misaka's lips touched the water bottle and movement of Misaka's throat as she swallowed the tainted water. Kuroko wanted to scream in joy but she waited and then drank her glass of water. 
 "This taste weird" said Misaka
 Kuroko could say the same thing with her water and at the same time both Kuroko and Misaka held their flat bellies as large groans came from within.
 "So...hungry" said Misaka
 Kuroko realized that the drug was the wrong kind and somehow some of it was in her drink. Kuroko was so hungry that if someone opened that door that would end up being eaten alive. 
 "Hey it's time to go to bed" said the dorm woman as the door opened up
 Kuroko looked up at the adult woman and teleported above her mouth wide open.
 "Huh" said the dorm woman
 Kuroko's lips slid over the dorm woman's head and heavy gulps started to intake the dorm woman. Misaka watched the dorm woman basically get inhaled by Kuroko until only the shoes fell to the ground and a wet gulp sent the dorm woman to stew inside of Kuroko.
*bwrrrappp*
Kuroko belched and patted her big squirming belly.
 "She really hit the spot but I could use a bit more" said Kuroko
 Kuroko blushed when she saw Misaka looking at her but a smile went across Misaka's face
 "Kuroko I think we can both fit about three people each in us I bet" said Misaka
 Kuroko smiled and both girls left their dorm to find prey. A girl was walking through the hallway when she noticed Misaka standing in front of a door about to knock. The girl realized it was her own room and yelled out to her.
 "If there something you need Misaka" said the girl
 Misaka turned to see her first meal and looked at Kuroko
 "The one inside is all yours" said Misaka
 The girl noticed the large belly on Kuroko but she teleported away. Misaka reached the girl and held onto her shoulders. 
 "W-what do you need Misaka" said the girl
 Misaka answered her with her maw widening and shoving the girls head into her maw. The girl struggled in Misaka's grasp so Misaka shocked her, making the girl go limp.
*gulp...gulp*
The limp girl was eaten whole by the railgun girl within a minute and curled up inside of her belly.
*bwarrraappp*
Misaka felt much better with a large piece of meat in her stomach and turned to see Kuroko walking out with a pair of feet outside her mouth.
*slurp...gulp*
Kuroko's belly grew even more as now two people struggled inside of her stomach.
 "Sissy I'm getting full but I think one more can fit" said Kuroko
 Misaka burped again and wondered which room should be next until something flew at them. They dodged and saw Kongou Mitsuko down the hall.
 "Ha ha ha I see you have eaten a few people but I'll save them from your..huh" said Kongou
 Before she could finish Kuroko was above her with her pants pulled down and her asshole showing. Kuroko's asshole landed on Kongou's face and was forced down further. Kuroko moaned with saliva falling from her mouth. Kongou squirmed but her shoulders were sucked inside of Kuroko's anus leaving her pretty much helpless. 
 "Oh yeah get in my butt" said Kuroko
 Kuroko's belly made her travel down Kongou's body much faster. Kongou screamed inside of Kuroko's anus as brown stuff rubbed against her face and the walls pulled her deeper through Kuroko's insides. Kuroko fully slid down Kongou eventually her ass hit the ground with a slap and a final slurp of Kongou's feet and she was gone. Kuroko sat on the ground and felt Kongou travel through her intestines until finally reaching her stomach. Kuroko spoke to her
 "Dont worry Kongou in a few hours you'll be sliding through them once again" said Kuroko
 With three people squirming in her belly Kuroko was full and decided to go digest them all in the dorm women's room.
 "Misaka I'm going to the dorm women's room to digest so meet me there when you're ready" said Kuroko
 Kuroko teleported away leaving Misaka to stuff her belly with two more people. Misaka looked at her belly and spoke to it.
 "Ready to have friends" said Misaka
 *gurgle*
She was already digesting the girl inside who was limp from the shock. Misaka looked down at a dorm room and noticed the lights were off already. Patting her belly Misaka walked the door and easily opened it. Misaka was happy no one noticed anything weird happening outside their rooms and most were still asleep. Misaka licked her lips and went to the first girl. She picked her up and Misaka started to swallow. 
*gulp...gulp*
The other girl heard some weird noises and woke up to find her roommate half stuffed down Misaka's throat. Before she could scream Misaka sent a shockwave directly at the girl making her immobile and not able to speak. Misaka pushed down on the girl who she was already eating and slurped her fully down. The girl on the bed watched her roommate bulge the stomach out more and saw that there were two people inside. The girl tried to speak but it was too late. Several gulps and slurps later a bloated Misaka left the room with a large belly that almost didn't get out of the door frame.
 "Ugh maybe I overdid with three" said Misaka
 *bwarrrrpppp*
Misaka burped and pair of green panties with her favorite character Gekota on it. Misaka could not help herself and took the panties with her to wash and where. 
*blorp...churn*
Misaka waddled to the dorm women's room where Kuroko sat on the chair with her squirming belly on the desk. Kuroko was busy digesting her three slabs of meat as Misaka pulled a chair and sat down with her belly hanging low.
*gurgle...groan*
The room was filled with both girls churning their meals into soup. 
 "Sissy this is fantastic I wish we could digest people together forever" said Kuroko
 Misaka smiled and hugged her belly, getting a few yelps from inside. Hours pass and the six girls that were eaten were churned down into a thick paste with not much to identify them with. The humanlike shapes rounded out leaving Misaka and Kuroko with sloshy bellies full of bone and muck. Misaka and Kuroko moaned as they absorbed their meals and gained a good amount of fat. Their busts turned into F cups, Kuroko's ass was really stretching her pajamas bottoms out while half of Misaka's ass was sticking out of her skirt and of course they had thighs that could turn bones into jelly. As they got fat both girls came to their senses and realized what happened.
 "Sissy um...I'm sorr-"said Kuroko
 Kuroko's eyes widened as a pair of lips pressed against her own. Kuroko was in awe as she found it was Misaka kissing her. 
 "Usually when you have some dumb scheme to seduce me I'll get angry but this time around I enjoyed eating all these people with you...Kuroko I love you" said Misaka
 *flwarrrrppppppp*
Both girls' eyes widened as the sweet moment was interrupted by both girls letting out wet farts. They giggled and both girls stood on the dorm woman's desk with their bare asses towards each other.
*plop thud*
Shit poured out of both Kuroko and Misaka as the wet logs hit the desk. The six girls were nothing more than waste with little bones and hair mixed in. Kuroko and Misaka didn't feel bad at all for churning them all away. As the pile grew the two preds slowly stood higher so their butts would not hit the poop. Misaka had spread her asscheeks to let the large turds come out. Kuroko was sweating and moaning to the soft shit coming out of her. After several minutes a four foot pile of scat was left of the six girls that were eaten. With paperwork the girls wiped and got off the desk. Kuroko teleported her and Misaka outside and they held hands. As they walked their fat asses jiggled and Kuroko spoke.
 "Miss Saten and Uiharu might make yummy meals don't you think" said Kuroko
 Misaka smiled and they made their way to Saten's apartment.
 Elsewhere an hour before hand
 With her hand soaked in pussy juice and her other hand grabbing her tit Misaki was in another world of pleasure as she was controlling one of the girls Misaka ate and felt the whole thing.
 "I need Misaka to digest me as well" said Misaki
