Wanting nothing more then to get a few hours of sleep, Princess Peach forced herself to roll onto her side after hearing a thunderous belch next to her. Tilting her massive frame over, the sight that greeted her was her pink lover sporting a belly more then half her size. Blinking several times, Peach had to convince herself that she wasn’t seeing things before she opened her mouth to speak.

“Amy?” She attentively said, noticing a glimmer in the girl’s eyes that she had never seen before. If Peach had only known, Amy had spotted the same glimmer in her eyes earlier today after she had eaten Sonic.

“Mmmmmm,” Amy hummed mindlessly, running her hands up and down her shaky belly. The girl was zoned out and seemed to be stuck in a stable state of elation until a loud gurgling sound issued from her body. “Mmmmmm Sonic!” Amy squealed and Peach’s mouth opened in shock. It didn’t take much to figure out the reason Amy’s belly was so big. Even a Goomba could grasp that Amy had eaten Sonic and was now in the process of digesting him. Peach went pale, Sonic was in serious trouble.

Back on the battlefield when she had eaten him, it had happened during a sanctioned match where no one was ever permanently hurt. Sonic had been revived after Peach had digested him due to Master Hand’s interference after she beat him. But this wasn’t a sanctioned match and there was no godlike being resurrecting fighters. If Sonic was digested, he was going to stay digested.

“AMY STOP!!! SONIC’S IN DANGER!!!”

“I am?”

Peach’s face snapped upwards to see Sonic the Hedgehog in all his glory, standing on a glowing platform usual seen in the Smash Bros tournament after a player is knocked away. The blue blur looked as confused as Peach, looking around the room in bewilderment. A few seconds later the platform disappeared and a very confused hedgehog fell to the bed beside his royal lover. The pair exchanged looks, both asking the other silently what the hell had just happened. The last thing Sonic remembered was feeling itchy inside Amy’s cramped gut before finding himself hovering over the bed. Before a word could be uttered, the growing moans of Amy reached Sonic and Peach, and they turned to watch the pink hedgehog go through a starting metamorphosis.

It started with Amy’s huge belly slowly withdrawing back into her body. With every inch of her belly that disappeared, her skin seemed to puff out. At first it happened all over her body. Her thighs got bigger as her arms did. Her face got rounder as her hips did. All of her flesh was swelling at the same rate. But then certain parts of her became bigger faster. Her breasts started to expand quickly, changing from a pair of perky C-cups to double D-cups in seconds. Her hips expanded further, matching her potbelly that remained from eating Sonic. Amy was thrashing by now, parts of her becoming bigger then other parts. She rolled onto her stomach, exposing her ass which was getting bigger and bigger by the second. Sonic and Peach could only watch as Amy’s ass became huge. The girl had always had a bubble butt, a fact Sonic knew too well. However, now those pale pink moons were the size of bowling balls each. As Amy shook, her ass cheeks smacked together, illustrating that now they weren’t just bigger, they were more supple too. Amy was getting fatter and fatter by the second, turning into one big jiggly ball. With a final squeal she finished bloating out. Falling onto her back with her arms spread out, gasping for air as she stared up at the ceiling blankly.

“Amy? Babe, you okay?” Sonic nervously asked. He reached out cautiously towards his girlfriend like she might bite him because quite honestly she just might. She was so fat now, but he noted thoughtfully that she was still not as big as Peach. If he had to compare the girls, he’d call Amy portly with a huge ass and Peach extremely overweight all over. Shaking his head, Sonic recognized he shouldn’t be come paring shapes right now, Amy might need him.

As soon as Sonic placed his hand on Amy’s thicker shoulder, the girl started to rise. Pulling herself up, Amy stared blearily at Sonic before diverting her eyes to her own hands. Staring blankly at her chubby fingers, lost in the sight of them for nearly a minute, Amy pulled her eyes away from them and rolled off the bed. Stumbling onto the floor, with as much haste as she could, Amy moved towards a full body mirror across the room. Nothing was said by Amy as she stared at her reflection as though she was entranced by the very sight of herself. Finally, she pulled herself together and let out a cry.

“YYYYYYEEEEESSSSS!!!!!” Amy gleefully screamed, pumping her fist into the air in triumph. She spun around to face Sonic and Peach, a smile nearly overtake her whole face. “Look at me! I’m so big! I never thought my body could reach this size! Just look at my chest! Who’s the flat one now Rouge!” Grabbing her huge chest to show off their new size, Amy caught the reflection of her ass in the mirror and let go of her goods in surprise. Shrieking again, Amy’s smile now threatened to split her face in half. “My ass is magnificent! It’s better then Rouges! It’s better then Vanillas! Its even bigger then Peaches! YYYYYIIIIPPPPPEEEEE!!!!”

A collective sigh of relief was let out by Sonic and Peach at the sound of Amy’s joy over her new form. When the newly bloated hedgehog had gone early silent at the sight of her new form, both lovers had feared she would be repulsed or angry over her new look. But hearing her rapture put their worries to ease. Although, Peach had to argue that her massive booty was still superior to what Amy had, but she wasn’t going to say anything. It was so good to see even with her body changed, Amy’s mind was almost unchanged.

After checking herself out again in the mirror and making several suggestive poises, Amy turned back to Peach and Sonic, still lying comfortable on the bed. Licking her lips, Amy waddled towards them, running her fingers down her fat and quivering body. “Lets Fuck!”

Peach grinned. Adjust that, Amy’s mind was completely unchanged. She was still the same oversexed vixen as she was before getting fat. Wrapping her arms around Sonic, Peach beckoned her other lover to bed. There was so much more of Amy now, she had to personalize herself with every inch of fat the girl now had. The same thought ran through Sonic’s head as he stared at his one and only. He had never seen her more sexy then she was now and he wanted to be with her more then ever. He wanted her, so he’d take her because he was Sonic the Hedgehog, the one and only.
