Bertie stood behind his big brother, Alfie. He licked his lips hungrily as he eyed the large, ripe mound of furry butt in front of him. Bertie had waited all week for this moment; he had been teasing Alfie relentlessly, stroking his long, hard cock whenever his brother was within sight, driving the older kangaroo horny and desperate for relief. Finally, the day had come, and Bertie was ready to act.

Bertie grabbed Alfie's pants and pulled them down, exposing his brother's soft, fluffy rump. Bertie rubbed his face in the warm, soft fur, taking in Alfie's sweet musky scent. Bertie pushed his tongue out and ran it along Alfie's crack, licking him from taint to tail hole.

"Oh fuck!" moaned Alfie as his little brother tongued him. Bertie grinned wickedly. He loved to hear his big brother's sexy moans, and he couldn't wait to shove his cock inside Alfie's tight, juicy asshole.

Bertie spit on Alfie's hole, working it with his fingers. He finger-fucked the older kangaroo deeper and deeper, loosening him up for what was to come. Bertie pushed them all the way inside, feeling his brother's wet, velvety walls contract and grip him. He jerked his own dick, getting himself even more excited.

Bertie thrust his digits in and out, spreading Alfie's hole ever wider and looser, making the older roo squirm and squeal with pleasure. Once he judged his fag brother's hole to be loose enough, he withdrew his fingers and shoved his thick, throbbing rod inside Alfie's slick, hot hole, immediately getting to work breeding that tight ass.

"Take it, slut! That's what you get for fucking little kids!" Bertie said as he slammed his hips into Alfie's ass cheeks. "You know I heard you jerking off to me when I was taking a bath. I guess you can't help it that you're a pervert, huh?"

"N-no, I... Ahh, Bertie... You have such a big cock..." Alfie moaned as his little brother thrusted deeper into his tight ass.

Bertie grunted and reached down to grab Alfie by the back of the head. With his free hand, he reached around and grabbed the tip of Alfie's cock. He smirked as he felt how wet and slick his brother's shaft was.

"Gross. You're soaking wet, you sick pedophile. I can't believe you're turned on by a 12-year-old kid fucking you," Bertie sneered. "Are you ready for me to make you cum like a little bitch? Maybe become my food too, after... turn you into a nice, fat, smelly dump...~"

"A-ah... Yeah, fuck... Bertie... make me cum... Make me your dump..."

Alfie's arms and legs began to tremble as he leaned his face onto the bed sheets and continued to moan loudly. His balls tightened as the hot and heavy feeling between them was close to climax. With an almost pained grunt, he sprayed his load onto the sheets while Bertie released his own in his brother's ass. He fucked his hips back and forth as he pumped his big brother's ass with his hot spunk. After his load finished, Bertie fell back into his seat and gave a long, pleasured sigh.

"... U-uh, you didn't mean anything you just said, r-right? Because we both were having fun and..." Alfie asked. Bertie stood and winked, that nasty grin still on his face as he shook his head. The young roo boy's belly rumbled loudly, and Alfie gulped. "O-oh no..."

"Come here, you gross pedo... I'm hungry and you're on the menu."

Bertie lunged forward, his maw wide open, and he started shoving Alfie into his eager, hungry gullet. The young roo boy's gulps were loud in ALfie's ears as he was swallowed down, inch by inch, doomed to fatten his preteen brother up and get shat out into the toilet afterwards.

... And yet, as he was chowed down, he was getting off to it. When had he become a deviant, too? Alfie was far too confused about this all to think at the moment, as all he wanted was to be able to breathe again. It didn't seem likely as the world grew dark once the final bits of his legs and toes sank into Bertie's throat. And so, the pedophile roo was soon to be no more in a most kinky, erotic fashion.

Bertie let out a huge belch and patted his belly, the curves of his big brother's body visible through the taut skin and his belly already groaning and gurgling, eager to break Alfie down into mush. "That felt so good, not gonna lie... you're definitely gonna be the fattest pile of shit later, big bro~...."

No reply came from his stomach, and Bertie found that to be incredibly funny. Alfie's hands were just peeking out of the end of his bulging gut. He poked his brother's fingers, still hearing the squirming, desperate noises inside of him.

"Naughty big brothers need to be eaten alive like the gross boys they are. No one is gonna love them for who they really are but a slutty twelve-year-old boy... hee hee, oh you're probably getting off on this, aren't you?"

Another rumble echoed in his guts, and Bertie figured that meant yes, Alfie was definitely aroused from the fact his little brother was eating him alive. "Just wait 'til the end... it'll feel so fucking good..." He thought, feeling up his belly while letting the rumbles carry him off to dreamland, knowing that soon, he'd need a large load of toilet paper for all the thick logs that were going to be leaving his bowels... and then he would go after even more dirty pedos like Alfie... gulping them down and turning them into big, nasty piles too.

This had been his fantasy, all along, and with Bertie's advent into adulthood and his hyperactive bowels, he couldn't stop himself from making it reality. How had Alfie thought this was all weird? He was clearly into this too. Such a dummy, that guy was. Bertie could only laugh.

Hours later, after Bertie's belly had smoothed out into a nice, round ball of pudge and fudge, a nasty fart squeaked out from between Bertie's newly-plump ass cheeks and the first log of former Alfie started to crown from his little pink pucker. Bertie smirked and waddled his way to the toilet, plopping his new fat, juicy ass down on the toilet seat and sighing as he began evicting his big brother from his bowels.

Plop after thick plop, inch after inch of Alfie squeezed out from his sphincter, the adult roo now nothing more than fat logs of greasy crap. Bertie's guts had made efficient work of Alfie, liquefying the roo man's flesh and meat and pulverizing his bones into unrecognizable fragments before draining the thick slurry into his intestines and absorbing everything they could from the useless pedo. Turning that kiddy-fucker into rolls of fat he'd use to lure even more pedos to their smelly doom.

The pungent odor of fecal matter filled his nose, the silence broken by the occasional plop of turd and Bertie's grunts of effort with each one. But before long, the few dozen pounds of shit had been squeezed out and Bertie hopped up off the pile--having filled the toilet that much--to examine his handiwork.

"Ahh, there's the big, bad, stinking pile of pedophile right there... Enjoy your new home, big bro," he snickered as he flushed it. But this wasn't the last time he would ever see the corpse-turned-clog of his brother. His insatiable bowels demanded more fattening for Bertie's next victim... and oh there were plenty of targets, for there was an entire world of perverts out there, and Bertie had the appetite of an unapologetic beast.

Bertie chuckled deviously, his belly grumbling as he thought about his next perverted meal...
