Megumin yawned as she walked through the mansion her and her party lived in and she passed by Kazuma's room.
 "Damn it this world isn't close to what I had imagined, next time I do I'm getting reincarnated" said Kazuma
 Megumin's eyes widened hearing that and she rushed back to her room, grabbed her witch hat and straightened her dress so her black panties wouldn't show and then she was off. Megumin looked far and wide through the town until finally she had found a spell that would be perfect to keep Kazuma around. She blushed thinking about what it was but for the first time ever Megumin had learned a new spell other than explosion. Megumin gulped and then headed back to the mansion since everyone was tired and wanted to stay in that day.
 "That Kazuma isn't leaving us..no he can't" said Megumin
 Megumin stood in front of Kazuma's door and looked both ways before grabbing the handle and opening it. She found Kazuma snoring away with only a towel on. Megumin was relieved he was asleep as her plan would not go so well if he was awake. Quietly she shut the door and looked over at Kazuma. Then slowly she lifted her skirt up and wrapped her fingers around her black pantied and then pulled them down off her thighs and tossed them to the side for now. With her dress lifted and bare ass showing, Megumin turned around and held Kazuma's feet. Then she pulled him a little till his toes touched her asshole making her blush and then with one hard pull Megumin's tight pink asshole opened up and slurped Kazuma's feet up to his ankles.
 "Ugh..it hurts but feels so good at the same time...I'll go through it for you though" said Megumin
 Megumin let go of him and bent down letting her butt do the work. Automatically the insides of her ass started to pull more of the sleeping boy. The wet sound of Kazuma's flesh sliding against the insides of her anus and the feeling of her asshole stretching further as more and more of him was sucked in. Megumin moaned and did her best ignoring the pain. Kazuma's knees were gone and Megumin started up on his thighs making them clap together. Megumin turned around and reached behind removing the towel to see his limp small dick. Megumin blushed and watched as the penis went out of her view behind her ass cheeks but then felt it graze her butt hole and was of course slurped inside. Megumin heavily breathed with her tongue out and spit dripped from the tip of it. Megumin placed a hand on her moving insides and another on one of her asscheeks parting it a bit from her anus and moaned.
*shlip..slurp..shlck*
Megumin sucked in Kazuma halfway reaching his hips.
 "Halfway there just a bit more he's all mine" said Megumin
 Megumin grabbed his hands and placed them to his side as her assholed went on for his midsection. The anus slid over his hands and now the anus was inching past his belly button. Megumin kept looking back and loved the feeling now and had gotten used to the pain. Kazuma stirred in his sleep but even if he did wake it was too late for him. Megumin's asshole went over his chest and slid over over his shoulders and that's when it happened. Kazuma opened his eyes and looked to see a blushing Megumin looking at him and then he looked forward to seeing both her ass cheeks and practically his whole body in her asshole.
 "What the hell" said Kazuma
 Megumin would rather Aqua and Darkness not walk in so to end his screams Megumin put her hand on his head and pushed. Megumin moaned and Kazuma tried to scream but after a wet slurp and the asshole wrapping around Megumin's fingers it was done. Megumin took her fingers out and wiped the ass slime off on her dress. Kazuma squirmed in her guts the entire time and eventually found himself in her stomach. Megumin laid back and flopped on the bed feeling very stuffed. Half her belly was covered by her stretched dress and the other half was bare. Megumin stroked her large gut that started to move around and muffled pleas came from within.
 "Now just calm down and let me digest you trust me it'll be better this way" said Megumin
 "D-digest me how on earth is that better let me out right now" said Kazuma
 "Please just let it happen...the spell makes it so it won't hurt so just melt and become my fat" said Megumin
 She didn't want to reveal anything yet so she tried her best acting harshly to have him settle down. Of course that had the opposite effect as he squirmed more. His feet and hands pushed against her stomach walls as acid poured in but Megumin wasn't lying as the acid was still melting him but there was no pain as she didn't want him to feel pain while being digested.
*bwarrrappp*
Megumin belched from all his moving and rubbed her poor tummy as it was hurting with all his moving.
*gurgle..glorp*
The sounds of her stomach processing Kazuma picked up and his muffled talking became even less audible. It was kinda sad not hearing him but the sounds of digestion were fine to listen to. Megumin continued stroking her belly brushing her fingers across the moving bulge and was trying her best to enjoy herself. Megumin sighed and just wanted it all to be over soon.
*churn..blorp..groan*
Kazuma struggled but he could feel himself becoming weaker and weaker. Megumin's stomach acids were awfully strong but he remembered her mentioning a spell so he assumed that must have accelerated the digestion process. Either way Kazuma had no way of getting out and Megumin was pretty keen on digesting him. Kazuma sighed thinking what an awful way to go but at least he could be reincarnated this time.
*groan..slosh..glop*
Kazuma felt his mind slipping as the acids were making him feel very goopy and the walls were pressing down on him. Megumin felt Kazuma stop moving and poked at her belly feeling it become soft and squishy. She smiled as soon enough he'll be mushed up and thrown through her intestines again.
 "Then you'll be a part of me" said Megumin
 Megumin hugged her belly feeling her arms and head squished in and somewhat breaking Kazuma a bit. His bulge became round and deformed as his body melted away and fell apart. Kazuma had passed out by now and didn't feel anything the entire time. The stomach crushed up his body reducing him to bones and slush. Megumin smiled seeing a nice round belly and even shook it hearing the bones rattle and mush slosh around. Megumin giggled at Kazuma and waited to add him to her body.
*slosh..crack..groan*
Megumin kept poking at her squishy belly having fun with it as it continued processing Kazuma. But soon enough the stomach was done with him and Kazuma was pumped into her guts. Megumin moaned as her belly shrank down more and more until only a little pudgy belly was left. Megumin's chest was enhanced a little but she would still be considered flat. Instead most of it ended up on her rear end so much that half her ass was poking from her dress. Megumin pouted and then she heard Kazuma.
 "What the hell..wasn't I just digested" said Kazuma
 Of course the only person who would ever hear him now was Megumin.
 "Yep you were but the spell made you end up as sentient fat...you just ended up on my butt is all" sais Megumin
 Megumin fully lifted her dress and found her fat ass having a small tattoo of Kazuma's face when he was being digested.
 "Wait..I'm just ass fat now...what the fuck" said Kazuma
 As that was happening Megumin felt her bowels fill with Kazuma and her belly groaned.
 "Uh yeah but hold I have to release what's left of you" said Megumin
 "I can't believe I have to see my own body be shit out...why would you do this" said Kazuma
 Megumin felt a little pain in her heart and almost cried.
 "I ended up overhearing you when you said the next time you die you'll get reincarnated...I hated to think you would leave so I decided to keep you close for now...when we defeat the devil king I'll have you reform somehow I promise" said Megumin
 With that said Megumin still had to shit and proceeded on. Megumin grunted and felt her anus open up with a smooth log snaking out of her ass. Kazuma watched as his own body was just her shit now. The log fell from her ass and she moaned feeling the soft crap come out of her. It plopped on the ground in wet waves slowly piling up higher and higher. Kazuma hated seeing his body coiling up as a pile of crap for some loli with an explosion fetish.
*flwarp..spalt*
Megumin farted and a log shut out of her ass. The warm poop had very minimal bones other than some big ones like Kazuma's pelvis and rib cage but of course they were half melted. With her bowels almost empty her asshole pushed out a final last log and Kazuma cringed seeing his skull embedded into the last one. It plopped down and Megumin was done. She used the towel he had on before eating him to wipe and then turned.
 "Yikes you like gross like that..well I'll lock the room up and leave this here to help the reform spell when it's time" said Megumin
 Kazuma just went mind blank as he witnessed just the worst thing ever. Megumin got her panties and pulled them up but as soon as she reached her ass it was too fat and it got stuck. It took a minute to finally have her black panties wrapped around her ass cheeks. Megumin smiled and slapped her booty making it jiggle and left the room happy to have Kazuma with her.
