It was another night out for the Watterson parents and Darwin, and once again Gumball was left to babysit little Anais. Not that he thought much of it. He had a little game he liked to play with her. A very intimate, adult game. The two were in the living room, the curtains closed, the doors locked. Gumball looked a tad nervous when Anais sat next to him. 

 

"Uh, Anais?" Gumball asked. "Are we gonna... play tonight?"

 

The little bunny giggled and stood up, revealing her panty-less rump to her big brother. 

 

"Of course, silly!"

 

Gumball shakily rolled his jeans down, then his underwear, showing his flaccid cock to Anais. 

 

"I, uh... I didn't get ready. Sorry..."

 

"That's ok. We don't need that dinky little thing tonight~"

 

"What do you mean?" 

 

"It means I want you to lie down, please~" 

 

Gumball was as excited as he was nervous. He laid down on the couch, his head resting against the couch arm. Anais got up and stood on the couch before squatting over Gumball's cock, spreading her little pussy. 

 

"I haven't done this before, so I'll try not to get any on the couch..." 

 

Gumball then felt a trickle of warm fluids splash on his cock and balls, then it settling before staining his blue fur. His dick hardened - he knew she was peeing on him. Anais sighed in relief as the piss streamed from her urethra, shifting her 'aim' so it wouldn't run down Gumball's fur and stain the couch. She kept pissing for about thirteen seconds, her stream wetting up and sticking to Gumball's crotch and cock, making it twitch, before it stopped. She sighed once more. 

 

"That was such a good pee break..." 

 

She then backed up, her little butt in Gumball's face. 

 

"Now it's time for the fun to start~"

 

Gumball opened his mouth just in time - Anais sat down moments later, her pink pucker in the exact spot they wanted it to be. He licked around her ring before rimming her, his tongue feeling around her insides. Anais did her best to keep back her moans. 

 

"Mmf... You know me too well, Gumball! But I know you even better!"

 

Her hole squeezed around his tongue. She grunted. Then, a massive, wet fart blew from her tight asshole, blowing Gumball's tongue out of her. He tasted the fart - it was gross and meaty, but he wasn't hesitant to swallow and savor it while it blew down his esophagus. They get better and better every day, he thought. She pushed again, this fart stopping only for another one to take its place, the foul, foggy air taking up space in Gumball's mouth for him to obediently swallow. Another stinky mess of a fart, but that's what made it so tasty to him. Even... a little sexy. Gumball's dick kept twitching and leaking pre-cum while Anais farted, showing her he was enjoying it much more than the first time. 

 

"Heheh, you must really like my stinky farts, Gross-ball! Well I've got something even 'grosser' saved for you!" 

 

A heavy, moist fart that reeked of shit blew from her hole before a titan of a log inched from Anais' sweet little hole. Her hole stretched as wide as it could while Gumball sucked the turd like a lollipop, then wrapped his tongue around the beast; it was soft, greasy... Tasty. He let his little sister push out the rest of the turd in his mouth before he got to work on it, mashing the thick mess into paste as slowly as he could manage, wanting to savor this delicious meal his sister had so kindly served to him. 

 

Anais kept releasing more messy, shitty farts into Gumball's mouth as he chewed the log she had just released, telling Gumball that this was just an appetizer. But that didn't mean he had to hurry - he chewed and kneaded the turd into paste on his own terms, waiting until it was nothing but slimy muck before gulping the last of it. He rimmed Anais' loosened hole again - he could taste the turd inside Anais' ass long before it crowned from her. She moaned loudly, fingering her dripping cunny while her big brother rubbed the space between her shit and her rectal wall with his tongue. She squeezed her hole again and pushed hard, Gumball's tongue still inside her ass. 

 

"Nnngh! Bon appétit!" 

 

With a wet *SPLORTCH*, a giant shit snaked out from her hole, sliding on Gumball's tongue like gelatin, continuing unbroken. It pushed into his eager maw, making his cheeks puff out. Inch after inch took up space in Gumball's mouth, making him salivate. The rich taste of this warm log made him cum without even having to touch himself. 

 

I... I really love your poop, Anais! 

 

Meanwhile, Anais was having the time of her life, unloading such a massive shit in her big brother's mouth. It was never a mere game for her, but this time she suspected it wasn't a game for Gumball, either. He clearly desired to eat her shit from the way he rimmed her, and seeing him cum from merely tasting her shit was a new development. She knew now was the time to pop a question that would change everything for them. 

 

"Gumball? I know you're eating now, but... Do you... love me? If you do, then kiss my butthole and keep eating, because I've got more, if you want. If not... We can stop once we're done." 

 

She passed the full load, letting it plop into Gumball's mouth with a wet fart at the end. She turned and giggled at his chipmunk cheeks. Gumball himself was in heaven. Shit juices leaked down his throat while he chewed the gargantuan load Anais just dropped. His eyes rolled back in pleasure. He chewed and chewed, like Anais' shit was a big, lengthy piece of caramel. To him, it was tastier than caramel, her rich, musky flavor and sweet, potent aroma more decadent than the finest, fanciest meal.

 

Mmm! Anais, I'll do anything just to eat something this tasty ever again!  

 

As the minutes dragged on, Gumball's cheeks gradually decreased in size. He alternated between chewing up some of the shit and swallowing whole sections of the log intact. Anais stood up again, letting Gumball close his mouth before she sat on his nose, her hole caked in shit and moisture. 

 

"Here's hoping you like it as much as I do." 

 

*pshhhh... Phraaaaapppp!*

 

She blew a hot fart in her brother's nose while he diligently ate his meal. He stopped chewing to take a deep breath. He inhaled deeply, taking her musk and stink deep inside his lungs. He exhaled, then sniffed again, fart juices resting inside his nostrils. She released another fart, this one quiet - but its stink was incredibly powerful. Now nearly finished with his sister's meal, he sniffed up her raunchy fart and realized something - he had finally begun to not only accept, but respect Anais's farts as the aromatic, erotic bursts of natural perfume they always were. 

 

Anais' wet stink in his nose and lungs, Gumball happily chewed up and gulped down the last of his little sister's delicious meal that she had so eloquently prepared for him. He gulped hard, his tongue stained with shit, his saliva filling up his mouth even when he had already finished. The last of Anais' turd traveled down his gullet and into his gut, a gut that had gotten quite a bit bigger since they started. Anais sat back on his mouth. 

 

"So, uh... You still hungry?" 

 

Gumball didn't even feel like messing with her - he spread her asscheeks and passionately French kissed her dirty asshole, his lips meeting with Anais' hole as she squeezed it. He licked up her insides, gulping down leftover shit chunks that didn't make it out, as well as giving her anus and rectum such a thorough cleaning that one would think she had never taken a shit once in her life. And of course, Anais 'kissed' back with a heavy wet blast of a fart that revitalized Gumball. Gumball closed his eyes, letting Anais sit down on him, eagerly letting her use him as a seat and a toilet. Anais, finally reaching orgasm, let warm juices trickle down her pussy and onto Gumball with a smile. 

 

"Thanks, Gumball. Now get ready, because you're gonna have a big night ahead of you!" 

 

She pushed an epic, legendary blast of hot gas into Gumball's mouth before a fresh turd popped out from her hole, long and thick, just the way he liked it. Gumball was happy as ever while starting the night reborn, a new boy. 

 

Anais... Please do this every night... Every day... You can do this to me here, at school, in public, I don't care... As long as you can feed me, I'll be forever grateful!
