Highschooler Deku aka Izuku Midoriya stood in front of a small orphanage with a smile on his face. Wearing his U.A highschool uniform he walked right in and used his quirk to take down any adults. The ten kids who stayed there all huddled up scared out of their mind from the green haired boy smiling as he took all the adults out. Deku went into the room where all the kids of varying ages sat and looked down on them, licking his lips.
 "I've really been holding this in" said Deku
 The feminine looking boy with a thick ass dropped his pants and underwear freeing his large dick and fat ass. Deku's goal was to make his ass fatter so shoving a bunch of tykes up his butt and digesting them into ass fat seemed like a fantastic idea. Deku grabbed a small girl by the leg and dragged her over as she kicked and screamed. Deku giggled and shoved the girl's feet in his ass making him moan and pull her in.
 "WAIT PLEASE NOOO" cried the girl
 The little blonde was slowly forced into the boy's slimy anus as his dick got harder and harder from the feeling. Moans escaped from his lips and all the kids were forced to watch their sister as she disappeared into the boy's colon. Her screams came to a sudden stop as her face slid in and the wet squelching noises of Deku's ass filled the room. The little girl was gone and Deku's stomach filled up with the first girl.
 "Who's next" said Deku
 Deku giggled as all the kids were frozen in fear not wanting to move but also wanting to run away and get help. But of course Deku knew they wanted to escape so he turned and slammed the door shut and locked it, sealing everyone inside and for extra measure he put a bookcase in front of it much too big for any of these kids to open it up. Deku giggled and all the kids screamed and scattered in the medium sized room. Deku was having a blast as he swung his full gut and knocked a small boy down. The last thing the boy saw was Deku's puckering pink asshole descending upon him. He screamed and squirmed as Deku moaned, enjoying his second butt meal. The little boy's skinny body jolted around as his shoulders and chest were forced into Deku. Deku had to grab his dick and force himself not to masturbate feeling the squirming tyke in his bowels. Deku curled his toes as the bare feet went in with a wet slurp and the boy joined the girl inside Deku's stomach.
 "So many meals...my ass is going to be so rump when I'm done with all of you" said Deku 
 Screams came from them all as Deku went back chasing them. Even with a full belly he easily was faster latching onto one boy and one girl and slamming them together. They cried as the sadistic Deku pulled them under his butt and shoved their heads in.
 "Oh fuck this is the best one yet" said Deku
 Deku felt pre cum come out of his rock hard penis feeling the pair squirming in his colon not wanting to be butt food. The asshole pulled and clamped down on the poor kids as they were forcefully sucked in. The pair soon enough went all the way up inside Deku and he almost orgasmed right there. His belly filled up more and more.
hhuuurrrprpoopppppp
Deku belched and some acid soaked clothing came out of his mouth. Deku turned around to see three kids trying to move the dresser and he found it cute thinking they had a chance. Two of the kids saw him and ran but the little red head girl didn't notice. Deku took his time as the girl cried just trying to move the dresser. He turned his ass and sat on her head as she let out a blood curdling shriek before her entire head was gone into the boy's tight anus. Slimy sounds and moans mixed with churning and screaming as the small red head could do nothing but beg before her little feet slid all the way inside of Deku. Deku put his hands on his giant moving gut pushing down the screaming faces and hands of his prey. He giggled and looked at the last five trying to stay as far away as possible. Only half were left and Deku wanted to do something fun with the final one. Deku scooped a pair of small boys and they cried. Deku laughed and shoved their faces against his full belly. They could hear their siblings screaming and begging for help.
 "That'll be you two here pretty soon" said Deku
 They cried even more before Deku felt something coming up his throat.
bwarrrrpppppp
Deku belched and an acid covered bunny t shirt slapped on one of the boys heads. Deku giggled and pushed that one down and then pulled the other under his legs and sat on his head. As Deku sucked in his sixth meal the kid took the shirt off his head and screamed seeing his sister's bunny shirt with holes from digestion. The kid looked at his siblings' legs kicking under the predator as they were easily slurped inside of Deku. "God sucking in you worthless twerps is the best feeling in the world...I'm sure you'll all make better ass fat than humans" said Deku
 Deku felt the feet slide inside his ass so he stood up straight and started to walk over to the kid with the bunny shirt. The kid crawled back and saw the belly move as the next victim was pushed inside.
 "Please..please spare me" said the kid
 "Fine I'll leave you for now you're the perfect size anyway" said Deku
 Deku turned the final three in the corner and went for them instead as the kid curled up and cried. The other three screamed as one by one the hungry Deku grabbed them and started shoving them in his ass. The oldest girl flailed the kicks as she went first with her feet going inside. Deku pinned the other two in the corner and they had to listen to the oldest being wetly slurped inside of the boy's butt. As her screams became muffled Deku grabbed the last girl and as soon as the arms of the oldest were gone he pulled the last girl under him and shoved her face against his asshole and it opened up. She cried and pushed her hands inside of Deku's butt cheeks but it did nothing other than arouse Deku even more. The urge to cum was filling his mind but he was persistent on not doing so. The girl struggled in his bowels and the stomach bloated out, squishing the boy in the corner even more.
gurgle...glorp..churn..blorp
The sounds of the gut working on all the other kids and their sad faces trying desperately to escape. The girl was gone as her bare feet were slurped in and the boy could do nothing as he was also placed against Deku's butt and it gladly accepted him. The boy didn't bother screaming or squirming, making Deku frown as his anus easily took in the limp body. With zero effort only one boy remained and he held onto the acid covered shirt crying.
 "Nice and full...time to digest them all" said Deku
 Deku stood up letting his giant belly drag against the ground as he went to the last little boy. He looked up before Deku slammed the boy into a wall and pinned him with his belly.
 "I want you to feel them all digest" said Deku
 Deku giggled rubbing his hands over his belly soothing it, letting it process his giant meat meal. Tears streamed down the kids eyes listening to the begging once again. Inside Deku the agony of the kids being digested was only getting worse. Their bodies were melting and mixing together as they burned alive. 
 "No we don't want to die like this" cried a little girl 
 But nothing was going to save them now. They were all soft and were easily breakable now. The walls were testing the children making sure they were ready to be ground up in a mess of meat and bones.
churn..slorsh..blurgle..glorp
The disgusting sounds of digestion filling the poor kids ears.
bwarrrppp
Deku belched and the underwear of some of the people inside splat against his full tummy filled with holes. The kid pinned to the wall knew his family was going to die soon. It was painful to be stuck and watch it happen. The first few kids that were eaten were crushed under as they were too soft and one by one each kid passed on and were melted together making a stew of melted kid and acid. The remaining few could only beg for their final sibling to rescue them only to be let down as the stomach walls collapsed and crunched up whatever survivors were left.
bwarp
Deku let out a small belch and giggled as all the moving stopped in his belly. Deku starts to move his belly side to side breaking bones and sloshing the soup inside.
 "Hear that..they are all gone now and soon enough you'll see them on my butt here soon" said Deku
 It really didn't take too much longer as the remains were thrown into his guts. Deku moaned and leaned back holding his belly. The kid watched it shrink down and it was exactly like Deku said. Deku's already fat jiggly femboy ass started to expand. The kids' siblings were fattening up Deku's rear and thighs, becoming nothing more than that. "Fuck it feels so good...my ass is so big I could squish someone under it" said Deku
 His belly went back to normal and Deku could not resist grabbing his ass and squashing the fat thing in his hands. Deku blushed and looked at the remaining survivor. Deku giggled and grabbed the kid.
 "Wait..you said I could live" said The kid
 "Only temporarily silly" said Deku
 Deku giggled and shoved the kid in his as making him moan. But this time Deku forced the kid on his knees and grabbed his own penis. Then using the kid like a dildo the sweating moaning horny mess of Deku slid his ass up and down the kid's body while masturbating.
 "HOLY FUCK THIS IS AMAZING" said Deku
 Deku went on as the kid cried and begged, feeling the slime drenching his poor body. The kid wondered what he did to deserve such a fate as he was used as a dildo. Deku had his fun and yelped as his asshole tightened and a fat glob of cum splurged on the ground making a nice puddle. "Been saving that up all month" said Deku
 Deku giggled and pushed his ass all the way down to the kids legs before standing up and slurping the final survivor inside of him. The kid cried, filling up the guts and finally reaching the empty belly his siblings all perished moments ago. Deku rubbed his large gut before a little belch came from his lips.
 "You orphans aren't going to be missed so you make perfect targets bye bye enjoy being ass fat" said Deku
 Deku laughed as the kid struggled for a moment before Deku used his quirk and made digestion super fast. It was all over in five minutes. Any human life inside Deku was gone as the melted slop of the final kid ran through Deku's guts and he joined his family adding to Deku's rump. With all ten orphans gone and turned into fat on Deku he grabbed his clothes off the ground that came off and moved the dresser before leaving the orphanage off to plan his next butt meal.
