Another lazy day at the Watterson house, another day for Gumball to lounge in his room without any clothes to weight him down. His toilet needed plenty of space to breathe, especially in the afternoon, which was its normal use period for the family. He gave his long, thick horsecock a few pumps, brown precum oozing out before a burst of gas erupted from the tip. He sniffed it up - yup, that was his mom's, alright. Still as warm and mouthwatering as when it went down yesterday. He gave his throbbing toiletballs a rub as they churned up the remnants of their meal last night. Nothing to end the day like a few homecooked loaves from mom. He closed his eyes, rubbing his dick as...   "Hey, Gumball?"   The door creaked open, and Anais entered.   "I gotta use your toilet."   "Oh," Gumball said, stopping the stimulation. "Well, go ahead."   "Thanks."   Anais climbed on his bed and made her way to the tip of his horsetoilet, her panties already off as she sat her asshole down on his toilethole. She reached behind her and spread Gumball's toilethole wide open, her asshole puffing out inside his toilet before...   *PLOOOOOOOORRRRRRRBBBBBBBBBPTPTPTPTPTPTPTPT!*   "Ahhhh..."   *PFRRRRRRRRRRRRRRRBTBTBTBTBTBTBT!*   A thick, raunchy barrage of hot, wet farts erupted from Anais' sweet, aromatic asshole. Gumball moaned, the gas pelting his urethra and traveling down into his sack. Just as usual, but never uninteresting. He relaxed and closed his eyes, Anais pushing a good thirty-second ripper down his toilet, a fraction of a second of silence before a fart that lasted over a minute.   *PLOOOOOORRRRRRBBBBBTTTT! PFRRRRRBRBRBRBRBRBRBRT! BRAAAAAAAAAP!*   Throughout her relief, Anais moaned and sighed, lightly stimulating her little pussy while blasting down Gumball's toilet. Fart after fart after fart blew from Anais' cute, teensy butthole. Gumball's toiletballs began to properly fill up, ready for the rest of the day. He gently rubbed her back, staring back at her with loving-kindness.   "Almost ready for the solids?"   "I've been ready for the solids. The farting was just foreplay."   "Then what're you waiting for? Let 'em rip!"   Anais nodded, closed her eyes, and clenched her fists. Immediately, Gumball felt the tip of a colossal turd crowning from his little sister's delicate foodhole. He laid back and psyched himself up while the thick, piping hot shitlog poked out of Anais' hole, its warm, greasy texture heaven to the insides of his toilet. Anais squirted all over Gumball's face and neck; the log had become easier to push. Her raw, rancid, beautiful shitstink began to fill up the room. The delightful mix of methane and other chemicals excited Gumball like nothing else, his horsetoilet as hard as it could be as Anais' hard, crinkly meal inched down his toilethole.   "Mmmmph... That feels so good," he moaned. "Makes me wish you could do this all day."   "Same," she said back. "I've been saving up for months just for this."   She laid on him and gripped him hard. Her foodhole winked before the monster of a turd pushed from her hole, its deep brown color visible through Gumball's shaft. Some of it had already begun to fill up his toiletsack, but most of it was just there, stuck in his urethra like a stinking, wet sex toy. Gumball felt his shaft throbbing with intensity and sexual pleasure.   "Heheh, guess it won't flush."   "Good thing that's not all," Anais said with a mischievous smile before Gumball felt another viscous log of food blort down his toilet. This one was much smoother, but by no means smaller. The log wormed down his toilethole with ease, adding a new layer of shitgrease to his already coated insides. His toilet was absolutely pulsing, begging to orgasm as the second meal began pushing against the first. He felt the turd begin to push against the tail of the first meal, making it coil and curl on top rather than dislodge. The base of his shaft, and soon, the rest of it, enlarged and swelled with glorious brown lumps as Anais kept pushing shitlog after shitlog down his toilet.   *PFRRRRRBTBTBTBTBT!... BLOOOOORT.... plrrbt*   A few wet, messy shitfarts concluded Anais' wonderful show.   "And that's it," she said. "Tank's totally empty now. Hope you loved it as much as I did."   Gumball kissed Anais right on the lips, truly loving his sister's meals and proper toilet usage.   "Thanks, sis," he tenderly moaned.   "You're welcome," she said as she hopped off of Gumball's toilet... Then, she caught a look at what she'd done. Gumball's horsetoilet was completely clogged, filled to the toilethole with her months-old turds.   "Oh, no... I clogged you! I'm so sorry!"   "It's alright. I bet that clog won't last long, anyways," he said with a smile.   "Heheh... Guess you're right. Still, I'm really sorry about that."   "Really, don't worry, sis. Everything's gonna be just fine."   "Okay... Thanks for letting me use your toilet."   "No prob."   Anais left his room without another word, leaving Gumball laying on the bed, Anais' intensely heavy musk and shitstink seeping through the pores of his toilet. The end of her last meal was still slightly poking from his toilethole.   Well, he thought, might as well finish what I started.   The door opened to his room once more.   "Oh, yeah, Gumball?" Anais asked. "Yuki's here for you."   "Oh, awesome! Send her up!"   Gumball grinned with anticipation as Anais left, hearing her and another, heavier set of footsteps going down and up the staircase.   Yuki's here, Yuki's here! he thought. Don't need to rub one out with her around!   "Gumball? Are you- oh my," her low, sexy voice rung in his ears. "And what happened there, sweetheart?"   "Anais used me just a moment ago, and she, ah... She clogged me. Whoops! Ah, well, it happens. So, you wanna use me?"   He used two fingers to push the lukewarm shitlog poking from his hole back down where it belonged, licking and sucking the smeared shitstains from his fingers. He couldn't notice it, but Yuki looked desperate, like she was in a hurry. She pulled her work pants and cotton undies down without a second thought, her bare, praiseworthy ass sticking out just for him.   "Please put it in," she gently ordered. "I really can't hold it much longer."   "No prob," Gumball said before plunging his horsetoilet deep inside Yuki's warm ass. She moaned in sexual delight, although they both knew that wasn't why she was here. Gumball gripped her thick asscheeks and pushed deeper, no signs of any logs or gas inside.   "You looked really nervous," he said. "Something wrong?"   Yuki didn't answer. She was breathing heavily, squatting with Gumball's toilet entrenched deep inside her. Her breathing got heavier and heavier; Gumball felt her insides loosen up before moving rapidly.   "H- here... Here it... Here it comes!" she exclaimed.   "Here what com-"   He didn't get to finish. A river of raw, liquid shit blasted down and around his toilet, her anus puffing out before brown matter trailed down the outside of his toilet, a puff of gas leaking out. And inside? Heaven. The onslaught of raw shit had simply pushed the clog out of his shaft, making him moan and curl his toes in delight as his sack began filling with scat. He gripped Yuki's ass even tighter as she did nothing but push. Push. Push. Every push gave another several-minute-long squirt of shit, and a new layer of coating for the outside of his toilet. Then, without warning, the smell of it hit his nose. It fucking stunk. It fucking stunk like nothing else he'd smelled from Yuki. And it was amazing.   "G- god damn, that stinks! God, that stiiiinks!!!"   A powerful wet orgasm rocked his 12-year-old body as Yuki kept dumping waste down him. He felt a thick, hot stream of shitty cum about to rocket up his toilet while Yuki kept pushing.   "G- Gumball... You ok back there? I'm so sorry about-!"   "I love you, I love you!"   "I love you, to-! H-! Here comes a big one!"   Yuki clenched her fists and pushed like nothing else. Before Gumball could experience sweet orgasmic relief, a wet shit blast rocketed down his toilet, sensing fully formed, solid turds plorrrbt down, covered by the awe-inspiring ocean of diarrhea Yuki was releasing. He felt his toiletballs balloon with fecal matter, growing ridiculously huge, their blue-brown mass blocking some of the window and glorping across the floor; not even his own mother could make them THIS big! She sighed in pure, joyful relief as she breathed in and out. Liquid shit began to pour from her hole and around the base of his shaft. It was absolutely glorious to Gumball.   "Y- Yukiii... Don't stop... Please, never stop..."   "Heheh... Sorry, Gumball, but... I just did."   He felt a thick FLOOOOOOORRRRPBT travel down his toilet hole before Yuki got off, her hole slightly dirty, but her insides blissfully cleansed. She looked down on him with a warm, loving smile.   "Thank you. Thank you so much, Gumball."   "Oh, maaan... Thank you, Yuki..."   Gumball looked down at his body. His toilet was absolutely covered in dripping liquid shit, his hole oozing with the stuff. His balls were so full that he couldn't even move due to their mass - he couldn't even see any light from outside.   "God-damn, you filled me up real good," he said with a lazy smile. "No wonder mom gets so jealous of you."   "Heheh... Come here, sweetheart."   She got on her knees, holding Gumball's head before pressing her lips to his in a drawn-out lover's kiss. She pulled away after a good twenty seconds, her lipstick marked on his lips.   "Again, thanks."   "Don't even mention it," he said. "Just come back whenever you have to."   "I'd love to. Anyways... Back to work. Your mother will be seeing quite the raise."   "The joys of nepotism."   "Joys, indeed! Goodbye, and... Maybe have a shower once those things get smaller."   Yuki giggled before leaving Gumball alone in his room, his body splayed out on the floor, his toilet blanketed in shit, his sack swelled to mammoth proportions.   Can't wait till mom gets home, he thought. She'll love makin' 'em grow this big.
