Chihiro sat in his room working on his program with a box of donuts next to him. He hasn't eaten any yet and it was going to be a reward for after. The skinny small femboy with light brown hair to his shoulder finished and smiled.
 "Finally now I can eat" said Chihiro 
 Chihiro was about to eat but then a knock came at his door. He frowned and stood up with his skirt swaying before opening the door. Standing there was the tan skinned swimmer Aoi.
 "Hi Chihiro Kyoko needs you on the double with that program" said Aoi
 Chihiro ran back and grabbed it before running out past Aoi to find Kyoko. The door didn't shut all the way and Aoi saw the donuts. She figured Chihiro wouldn't mind if she had some. Aoi went inside and went on the bed and opened the box. She started to eat the donuts and didn't realize until after she did that all of them were gone.
 "Hehe oops" said Aoi
 Aoi stood up and looked at the bathroom door and saw something odd. She remembered the whole lock thing and saw Chihiro had no lock.
 "Wait..Chihiro is a boy" said Aoi
 As that happened Chihiro finished his business with Kyoko and ran back to his room super hungry and excited to eat the donuts. Chihiro came back to hear Aoi say he was a boy and looked at the box of empty donuts. Aoi looked at the door to see Chihiro standing there with wide eyes. 
 "You are all my donuts and you know my secret...I can't let you leave" said Chihiro 
 He closed and locked the door making it a soundproof room. Aoi felt the mood take a drastic turn and stepped back as the small femboy made his way to her.
 "I'm sorry I'll get you more" said Aoi
 "No...I think I'll dine on something a bit bigger" said Chihiro
 Her eyes widened and she turned to get as far away only to trip. Aoi cursed but then felt hands at her feet. Aoi looked back to see Chihiro crouched down licking his lips making them shine. Then she watched his maw open up wider than anything she had seen before and shoved her feet into his mouth. Aoi yelped and screamed, scared for her life but of course no one could hear her. She cried and begged as the slimy tongue went around her bare feet before she was dragged back and a loud gulp sounded from Chihiro. Chihiro was starving and this swimmer would easily fit inside his belly. 
*gulp..glrk..gulp*
He gulped hard and felt his cock rising in his green panties loving Aoi's taste. Chihiro was becoming super horny off this and wanted to stuff his gut as quickly as possible. Aoi cried scratching the ground trying to get a hold of anything to save her. But it was hopeless as her lower legs were eaten by the ravenous femboy. 
 "No please Chihiro I'm sorry don't eat me" cried Aoi
 Chihiro moaned at the salty taste of fear sweat and gulped in the girl's knees working on the super thick thighs. They were so soft squishy in his mouth and he licked every inch of them. Chihiro felt his stomach bulge with the girl's feet as he went half way up her thighs. Aoi tried to slap him in the face but he grabbed her wrists making them useless.
*gulp..glrch*
Aoi's thighs were gone and Chihiro forced the dark athlete ass in his mouth and gulped it down making his throat bulge out quite a bit. Then he brought her arms down and swallowed the hands with the girl's waist. Aoi desperately tried to pull her hands out of the tight slimy throat but it did nothing as the gulps made it impossible.
 "Nooooo stop" cried Aoi
 Aoi's toned middle was swallowed up and her long legs were curling up inside of Chihiro making his outfit stretch out. It was so tight and slimy inside the stomach and she cried feeling a pool of acid sloshing around her legs. Nothing she did saved her as Chihiro swallowed her boobs and shoulders leaving only Aoi's head out. Tears ran down her eyes with Chihiro pushing down on her head with one final scream escaping her lips before he confused her whole.
*gulp*
Chihiro fully swallowed Aoi and felt her curl in his tight boy gut ripping his outfit and his big belly flopped on the ground. Chihiro felt super full and smiled rubbing the top of his gut.
 "You ended up being much better than any donut..fuck I'm so horny" said Chihiro 
 Chihiro struggled to stand but he did it with his big full gut hanging down. Chihiro pulled his panties down letting his fat nuts and hard cock hang loose before making himself at home on the head. Aoi was screaming and squirming inside him only making Chihiro more horny as he grabbed a hold of his shaft. He started to dry stroke a little making it even more hard before grabbing the lotion in a drawer and getting some on his hands. Chihiro twitched a little and moaned, rubbing his fat dick up and down enjoying Aoi's digestion.
*bwarrrrpppp*
Chihiro belched loudly making his belly tighten around Aoi making the swimmer yelp. Chihiro curled his toes as an easy cum shot squirted out his dick hitting the bottom of his belly.
 "Oh..that felt good" said Chihiro
 Chihiro smiled and focused all his attention to his gut now rubbing his lotion and cum hand on it loving the squirming inside. 
*bwarrrrppp*
Another belch escaped his lips as soft gurgles started to come from inside. His toes curled and he bit his lip feeling horny but he resisted masturbating. Inside his stomach Aoi was crying, barely able to move as the walls were wrapped around her tightly. Her boobs squished by her legs and stomach acids were drenching her entire body while Chihiro was enjoying it. 
*gurgle..glorp..churn*
Digestion was really settling in with the acid rising and her skin tingled. But it was turning into a burn making Aoi cry and scream even more. Becoming shit for some boy dressed as a girl was definitely not her to do list but nothing she did upset the stomach if anything Chihiro would moan to her squirming.
 "This can't be happening...I can't die like this" cried Aoi
 Aoi smacked the walls with her hands feeling her skin burning up melting into jelly slowly but surely. The acids sloshed around and Chihiro's cum covered belly was being hugged by the femboy.
 "I know it seems like I've done this before I haven't you are the first...I think I'm going to be addicted to this" said Chihiro
 The churning continued filling the entire room with gurgles with Aoi screaming in a massive amount of pain. Her clothes were torn and no one knew she even went into the room. The grim fate that awaited her drew with every second as her mind was slipping away and her body was becoming more and more mush like. Aoi started to hyperventilate and thrash around before going completely limp. Two hours passed after that with Aoi nearly dead neck deep in acid and Chihiro was rubbing his belly with a smirk on his face.
*flwarrpp*
He farted and giggled, feeling her finishing up and becoming mush to absorb. 
 "Bye Aoi..I'll see what's left of you soon" said Chihiro 
 Aoi heard that and ended up passing out. Her limp unconscious body was dealt with as the stomach walls collapsed crushing the poor swimmer girl down making her into nothing but a soup to be absorbed. All the bulges left the soft looking gut of Chihiro and he moaned feeling bones push against the stomach walls.
*snap..crunch..slorsh..gurgle*
The mush sloshed around with bones breaking and melting further down until the stomach was pretty much done pushing the remains of Aoi through his guts.
*blooorrttttt*
Foul farts shot from his bum as he felt his gut shrinking down. All the fat went straight to his ass and thighs making them super thick. Aoi ended up as boy butt fat and Chihiro now with a pot belly laid on his stomach pointing his sweaty ass in the air. He reached back and grabbed his fattened rear moaning while squishing the ass fat. As Chihiro did that his limp cock slapped against his fat balls and started to harden as the scat entered his bowels. Chihiro made his way into the bathroom and took his skirt off before lifting his ass over the toilet and smiled.
*flwarrrrpppp*
Another smelly fart came before the remains of Aoi made them self known. Giant turds started to push out splashing into the toilet. The massive creamy turds filled with bones and dark hair made him moan. Chihiro's dick rose all the way at the sudden amazing feeling of shitting such huge turds. The way his asshole was being strained felt like he was being reversed fucked with each log. 
*plop..plap..splash..splat*
The disgusting shit smelled horrible but he hugged the air not caring and loving the smell. The soft warm crap filled the toilet and a long log coiled out with the red jacket Aoi usually has on stained brown and wrapped in poop. It flopped down and he popped out the pelvis of Aoi dumping anything that his stomach didn't melt all the way. 
*plop..splat..thud*
Shit ran off the giant pile overflowing the toilet and splattering on the wall and floor. As it came to an end he dumped out a huge log with a skull embedded inside before finishing. It was the biggest shit ever and he was insanely horny after. Immediately after he turned around seeing the nasty brown sludge before spitting on his hand and grabbed his cock. He rubbed it and moaned stroking his cock while looking into the lifeless skull. Like before he bit his lip and curled his toes before moaning loud and ropes of cum splurged out and splat all over the overflowing pile. 
 "Wow..that was amazing" said Chihiro 
 Chihiro wiped his ass clean and grabbed his skirt before shutting the bathroom door and flopping on the bed with his newly fattened ass jiggly with each step.
