The sun was shining high on this beautiful Mobian morning. Birds were chirping, it was a nice, warm temperature, there was the slightest breeze among the trees, and the few clouds in the sky sat about lazily, looking like puffy lumps of cotton. Yes, there wasn't a single thing.. The tree tops suddenly shook as the force of an explosion rolled through the sky, smoke was rising in the distance and there were only more small explosions to follow.

Sonic and Dr.Eggman were at it again.

The 'good' Doctor was currently leveraging a bevy of brutal robots against his lightning quick adversary, and said opponent was knocking them down as quick as they came, in fact he was knocking them out faster than they could arrive. Something that worried the Doctor heavily.

"Well get a load of this!" Eggman shouted as a platoon of large egg like robots came up on the battlefield.

"Nice try Egghead, but these aren't going to keep me busy for long!" Sonic shouted as he began to bounce repeatedly between two of the large robots.

Eggman growled under his breath, the hedgehog was correct, but Eggman wasn't about to admit defeat! So he decided to strategically retreat instead. Besides, he already had what he wanted, the robots would do a good job at keeping Sonic at bay while he flew off with his prize. Smiling to himself, he held the green Chaos Emerald in one hand.

"With the one back at base, that leaves five more to go." Eggman said, laughing to himself as his personal vehicle puttered away across the horizon. What he didn't notice was the shadowy figure coming out of the nearby trees and heading towards him!

Meanwhile.. Some ways away from this epic fight, a young hedgehog girl with a green shirt, an orange skirt, a classic look if you will, and a can-do attitude was making her way towards said fight. She'd heard the explosions far off an began running towards them.  Explosions usually meant one thing, Eggman, which likely meant, Sonic! The little girl had a big crush on the blue blur and was intent on making her way to him! Unfortunately for her, the explosions stopped after a while and she was left with little idea of where to go, which is when she suddenly noticed a round shadow overhead, looking up, she wondered what was up there?

Up in the sky, Eggman's vehicle was rocking back and forth in the air, though that wasn't his fault, this upstart bat had ambushed him and was trying to take his Emerald!

Rouge has been scouting the area for some time, knowing the Chaos Emerald was close by, unfortunately she was beat to the punch by Eggman, and as she knew he had a device to locate the stones, she had decided to just call it quits for the day, that is until Sonic showed up. Observing the fight between him and Eggman, she watched the Doctor leave his forces to keep Sonic occupied, knowing he had very little to defend himself with, she made her approach and swooped in to grab the Emerald! She'd been hoping to make a clean getaway, but the stubborn man had a firm grip on her gem, and refused to let go, which is why they were currently pulling back and forth on it. Rouge using her wings to try and pull back in the air, while Eggman's hefty girth kept him firmly planted in his vehicle.

Getting tired of this, both mentally and physically, Rouge pulled back one last time, putting her all into it, she forced Eggman to stand up.

"You won't have my Emerald you thieving little cu-Aah!" Eggman screamed as Rouge suddenly let go of her grip, smirking as she watched Eggman jerk back, falling over the side of his ship.

"WAAaahhh!"  Eggman screamed as he fell down towards the ground.

Down below, Amy suddenly noticed something shift on the shape far above her, the morning sun made it hard to discern the new object in the air, and before Amy realized it, Dr. Eggman was hurtling towards her, frozen in shock, she opened her mouth to scream.

"AH-"

Back in the sky, Rouge lounged in Eggman's vehicle, waiting for the inevitable sounds of the Doctor groaning to reach her ears, she knew he'd survive the fall, but she'd be able to swoop in and grab the gem from an injured Eggman for sure. What she didn't expect however, was to hear the sounds of a young girl groaning below.  Quickly Rouge flew down to investigate, her eyes wide as she made her approach.

Down below she saw Amy Rose laying on the ground, her gut was ginourmos!  The little girl's green shirt had been ripped slightly as her belly bulged out in a comical manner. It didn't take Rouge long to figure out what happened to Eggman either, as she heard the muffled screams of the Doctor inside the little girl, seeing Amy's gut stretch out as a hand or a foot pushed against it also helped.

"Huh.."  Rouge said to herself as she began looking around, Amy was currently drooling slightly, her eyes partially closed as she laid there as if in a coma. The bat was more concerned with where the Emerald had landed. After a moment of searching and coming up empty handed, she turned her head back to Amy, realizing the Doctor really did have a strong grip.

Walking up to Amy's gut, she could see Doctor Eggman still thrashing about inside of her, but not nearly as much as when she'd first gotten down here.

"Hm..  I guess I'll have to get you out of there.." Rouge mused to herself, clearly not a fan of having to release the Doctor from his makeshift prison, but before the bat could begin to figure out the logistics of getting Amy to vomit him up, she noticed something peculiar.. Her eyes wandered down to Amy's skirt, her oversized gut had grabbed most of the bat's attention, but taking this second look showed Rouge that Amy wasn't rocking a pair of panties, but rather a puffy.. Yellow diaper.. Rouge stuck her tongue out a little as she noticed the diaper was soaked, slight white edges around the top clued her in to what the diaper's original color was, assuming that the sudden appearance of the Doctor scared the piss out of the girl, either that or Eggman just smushed her bladder and forced it all out. Rouge had no idea Amy still wore diapers, part of her thought she was just wearing it so she wouldn't have to stop while searching for Sonic, then again, that Cream girl was also still in diapers. When did kids potty train anyway, when did she learn how to use the toilet for that matter?

Shaking her head and clearing her thoughts, that didn't matter, though it did give Rouge an idea. She didn't particularly care for the Doctor, besides, knowing his crazy ass, he probably had a clone or something in case of emergencies, and while she wasn't looking forwards to the inevitable diaper change, it would be the easiest way to retrieve her treasure.

"Good news Amy. I don't normally pull diaper duty, but today's your lucky day."  Rouge smiled at the girl as she patted Amy's overly full stomach. Making Amy's cheek's bulge as let out a.

"Uuurlp!"

The next task would be getting Amy back home. Sure, she could fly the girl there, but that would take forever and probably hurt her back. So, flying back into the sky, she hijacked Eggman's ride and brought it down, lifting Amy's bloated body into it, by now the screaming had stopped and the little girl was out cold, which was fine with Rouge, she didn't feel any need to talk with Amy right now anyway. With that done she began to push the vehicle towards her place.

After a couple hours of flight the two arrived home, Rouge got Amy out of her lift to find that the little girls stomach had already shrank a little, although that didn't make the girl any easier to lift. Dragging Amy into her home, she brought her in and laid her out onto the floor in the living room.  She was tempted to do this outside, but the less prying eyes the better, speaking of which..

Rouge decided to just leave Amy for the moment, she had to wait anyway and assumed Amy wasn't going to be getting up anytime soon either. Rouge took the time to get rid of Eggman's transport, sending it off away from her place so no one knew it had been here.

Back in the house, Amy laid on the carpet while her body went to work. Loud gurgles echoed from her digestive tract, her body slowly, slowly, slowly, began to break it all down. Various noises streamed from either end of Amy's body, occassional burps forcing their way out of her mouth, while blasts of flatulence popped out of her backside. The giant mound that was her belly began shrinking, but some of it simply moved around. Amy was old enough that she'd finally lost all of her baby fat, but it was coming right back as her booty got a lot more jiggly, her thighs also grew as well. Though it was rather lucky she was so young, as most of it didn't stick, and after several hours, Amy was left with a little bit of a belly, but didn't look overly engorged by her recent meal.

By now Rouge was back home and was just waiting for the inevitable, staring at Amy on the floor as she sat on the couch, reading a magazine, suddenly intterrupted by a thundering bout of flatulence. Looking up with disgust painted across her face, Rouge's eyes widened as she noticed Amy's expression had turned from peaceful slumber to pained exertion. Seeing the writing on the wall, Rouge quickly evactuated the room and as she did, Amy evacuated her bowels.

The diaper strapped to Amy's waist began to convulse and expand, pooling out underneath her, the plastic stretched to accomodate the huge load she was pushing out into it, at several points the young hedgehog seemed to struggle for a moment, her legs kicking in her sleep, only for her to then sigh as another wave of backdoor brownies made it's way into her diaper. The evacuation of her bowels was punctuated with numerous bursts of flatulence, leaving the air musty with her foul aroma.

Rouge waited outside the living room for a good ten minutes before the sounds of flatulence finally came to a stop, and even then she waited another ten minutes to give the room a chance to air out, she'd left the windows open earlier. Then, she poked her head into the room, horrified at what she saw, and smelt.

A hand immediately went to cover her nose as she looked at the still sleeping form of Amy with a massively filthy diaper strapped to her butt, the girls skirt had been pushed back by the expanded padding which was about the same size as the hedgehog, the smell in the air made her gag, even with the windows open it smelled like a biological hazard in there.  Retreating for a moment, Rouge came back with some needed supplies.

Wet wipes, a towel, a rag, two trash bags, several pairs of gloves, and a face mask already over her face, she'd liberally sprayed it with perfume to try and combat the stench of shit. It was a mixed effort, she definitely still smelled Amy's doody but the perfume cut it enough to make it bearable, but only barely. Coming into the room, Rouge got to work.

Not wanting to spill the contents of the diaper, the towel was laid and she got to work opening it up, the sight of the actual mess made her nearly vomit, but she pressed on, extracting Amy from the diaper, and cleaning the girl up, leaving her on a towel in case she had any further accidents. With that done, she gathered the diaper up into a trash bag, then she baged it into another trash bag, and dragged the whole thing out.  Leaving Amy on the floor.

Hours passed, by now it was the late evening and Amy was just yawning, stretching, and sitting up. The hedgehog quickly looked around, wondering where she was, and what had happened.

"What?"

She said out of nowhere, mostly just confused, smelling the air, it smelled like a dirty diaper, although she quickly realized she wasn't wearing it, or any diaper for that matter, and her shirt was ripped a little. What happened? The last she remembered, Eggman was falling towards her?  She looked at herself, poking her belly.

"Did I get fat?"  she questioned.

"AMY!" The hegehog girl jumped in place, and turned to face the shout, seeing Rouge come into the room, the bat's expression was seething with anger and Amy suddenly felt very afraid as she piddled a little onto the towel beneath her.

"I spent an hour scraping through every inch of your shit!" Rouge yelled as she got closer to Amy. "I didn't find anything except for a skull, a few other bones, one boot, and a mountain of your crap!" Rouge stood towering over Amy, poking the little girl in the gut, Amy moved back as Rouge poked her until she was pressed against the wall. "Now you are going to march into the bathroom and sit on that toilet until!..?" Rouge paused as she noticed Amy's gut flashing green.  

Amy had been too scared to do anything, but suddenly her guts began to shift, a green pulsating glow came from her lower belly.

"Oogh.." Amy bent over slightly as she felt her body react, feeling like she needed to go poopy suddenly! Leg's bending, body tensing. Rouge immediately knew what was happening.

"Not on the carpet!" the bat shouted, having pushed Amy off of the towel, but before she could even reach out to Amy, the hedgehog's backside exploded. But not in the way Rouge thought it would. A miasma of green gas suddenly filled the air, coming out of Amy's butt, the room was filled with the thick green gas. Amy sighed in relief as Rouge began to cough and gag on the horrible smell, even after spending all that time going through Amy's dirty diaper, this still smelled horrendous! Rouge began to feel weak as she blindly stumbled about in the gas, tripping over her clothes as she fought to stay standing.

After a few minutes, the fumes began to clear, Amy stood, looking with wide eyes at Rouge, at eye level. Rouge looked down at herself, her clothes in a pile around her, her breasts gone, her height, she was as tall as Amy.

"What did you do?!" Rouge screeched as Amy began to laugh uproariously.
