*GULP!*

A huge and round bulge moved down Sonic's nearly nonexistent neck. He sighed happily, never once pausing from fucking his reptillian bitch. When his meal made it to his belly, that giant thing bounced and lightly hit Birdo, squishing into her sexy figure. The whore moaned from feeling his gut against him even more so, and Sonic licked his thick lips. Now he was sure he made the right move by eating Tails himself, he was way to tasty to waste on Birdo.

"Fuck me Sonic! You're so big! All of you is just so BIG!" Birdo cried out. She was stating the obvious, but she couldn't help it. Sonic's unbelievable cock had worked her pussy so many times, and even now as she felt it slamming in and out of her, grinding every inch it had against her filthy snatch, she loved every second of it. Bouncing on Sonic's cock would have been easy even without his help, as his belly was as bouncy as it was sexy on him. To Birdo, Sonic's fat was just another way he was able to tame sluts like her, and she welcomed any opportunity to be on it or squashed by it. He even had a big mouth like her, and she only wished to devour half as many people as he had. All of Sonic's body had given her such pleasure

He then just sat her there, balls deep inside of her, letting Birdo enjoy being so full and having his belly squish against the rest of her body. Sonic then rocked her around and around, making his thing scrape against every inch of her birth canal and womb. His slut let out long and drawn out moans and even swooned at the sight of the fat phallus bulging out from her abdomen. She grabbed her impressive rack, squeezing them at Sonic's pace and twisting her titties. As her tail began to wag though, Birdo found herself rushed forward and slammed into something furry and squishy.

"They all wind up here." Sonic said. Birdo couldn't hear him, but as he sank the bitch into his belly rolls, his grin had never been more savage. He knew that she, like his other sluts would always come back to him for another round, but if they disobeyed him, he could easily send them to Tails' fate. Speaking of whom, as Birdo let out muffled moans from within the belly fat, loud gurgling was heard as the last of Tails was broken down. Birdo gave the gut a kiss "Bye baby."

Suddenly, Sonic felt that he was ready to blow. He roughly brought Birdo out and began slamming her onto his cock like mad. Always striving to go out with a bang, Birdo became a blurr on his cock, but still she felt every ounce of pleasure Sonic was giving her. Finally, after heaving Birdo up and down too many times to count, and unknowinlgy speeding up his digestive system, Sonic grunted loudly and came inside of her.

"Oh fuck yes." Birdo spoke softly as she felt the seed filling her. She moved her hands down to stroke her tummy, now feeling so delightfully hot liquid occupying the space along with the cock. Said cock soon left her body as Sonic pulled her off of him. As his seed began to leak onto his fat belly, again Birdo had to state the obvious "Sonic, you fuck me so good."

"I know." Sonic smirked, never tiring of praise. Birdo may not be one of his top 3 favorites, but he had to admit she knew how to use her body. Speaking of which, he did think that she was right. She did need to put on a few pounds, that would definetely make him want her more. Then, as his belly rumbled and he felt a familiar pressure within his ass, he grinned sinisterly, knowing just what to feed Birdo.

"Hey, you still hungry?" he asked her. She nodded and Sonic told her "Get on your knees." She did as he said like a good bitch, and waited for what Sonic would serve her to help her get bigger and sexier just like him. She watched as he turned his back to her and then bent over, thrusting his mighty ass right her face. In that single thrust, Birdo's nozzle had slipped between the corpulent cheeks and soon another rumbling was heard, right before Sonic said "Open wide."

With a single fart, shit came blasting out of Sonic's ass and down Birdo's throat. She had no time to think, only swallow as such massive quantities of crap were practically flowing from her master's rear. So much excrement was held within Sonic's giant ass at a time, but right now he could overflow his own personal toilet. His living toilet's eyes rolled back into her head now as she finally wrapped it around what was happening. She was devouring Sonic's shit, and having tasted many assholes like her master, she even found this so hot and perverted. She was eating everything he had, including Tails.

After minutes of nonstop eating, Sonic finished things off with a blaring fart that burned Birdo's eyes and nearly blew away her bow. The fat hedgehog just sighed in relief, always enjoying taking a massive shit. He turned around to his toilet, finding her in a rather enticing state.

Birdo was left kneeling, rubbing her hands softly across her now MASSIVE belly. If she was still at her former height, it would have been touching the ground. Already her belly gurgled as it tried to process the contents, and Birdo belched "UUUUUURRRRRRRRRP!!!"

"Damn! Now I see why I treated Tails like shit." Sonic joked, fanning in front of his nose. Birdo's breath stunk, but just knowing why put a smile on his face. He just stared at his slut, as she moaned happily because of the big, stinky pile inside her gut. Earlier Sonic had finally knocked up Vanilla, now another of his bitches had a big belly for another reason.

"Got a little more room?" Sonic asked her. Immediately catching Birdo's attention, he bent over again, his ass cheeks pulling apart and revealing his hole that was still stained brown. Without another word, she began lapping up the leftovers.
