Richard was awakened to the sight and sense of Gumball's mouth and tongue wrapped around his hard dick. Rustling, he giggled as Gumball gave him his best blowjob yet. 

 

"Heheh, Gumbaaall! You little stinker!"

 

Gumball smiled as he throatfucked himself with his dad's dick, bobbing his head back and forth while sucking that cock like a pro. Richard was waking up as Gumball's moans got louder and louder, his boy's spit around his cock hardening it. He rubbed the back of Gumball's head, giving his son a warm, content look as his cock throbbed in Gumball's throat. Then, he pushed hard on Gumball's head, making Gumball moan loudly before Richard blew his load. He sensed Gumball's gullet grazing against his cock while ejaculate spurted from his dickhead. Panting, Richard took his hand off of Gumball and slouched in his spot on the couch. 

 

"That's the best you've done yet, Gummy... Whew, you worked me good!" 

 

Gumball pulled away from his dad's dick, breathing heavily and coughing as semen trailed from his lips. 

 

"Ugh... Oh man, I oughta do this more... Thanks, dad. Soon I'll take you and Patrick as well as I take Darwin and Rob!"

 

"Heheheh, maybe in the mouth, but not the butt!"

 

Gumball chuckled along with his dad before setting his bare blue ass on Richard's flaccid cock. 

 

"I, uh... I decided to treat you because... I've been holding it in for a few days, and... I wanted to use your toilet."

 

"Wha? Oh, go ahead, Gumball! You just have to ask me up front!"

 

"Thanks, dad!"

 

Gumball pointed his little blue pucker at the entrance to his dad's cock. 

 

*phrrrrrrbbbbbbptptptpt*

 

Gumball released a wet, earthy fart that Richard sniffed up. 

 

"Mmm, you're getting stinkier by the day!"

 

"Heh, thanks..."

 

*PPPLOOOOOORRRRRRPPPPPBBB!*

 

Gumball ripped another fart, this one much louder, its stench heavier. The two boys sniffed it up, Richard leaning in to kiss Gumball as Gumball kept farting. 

 

*FLRRRRRRPPPPT! BLOOOORRRRRPPPP! PHRRRRRRBBBBBBTS!*

 

Gumball sensed a thick dump working through him. 

 

"Here it comes, dad..."

 

His hole right next to his dad's cock, Gumball grunted before a sloppy, wet fart burst from his hole. Richard's cockhole was opened up by the thick, swampy blast, which set the mood for both of them when Gumball pushed out a thick snake of a dump from his retracting asshole. It slid from his pucker, slimy and brown, the tip entering Richard's dick before the shit wormed down his urethra. Richard sighed in pleasure, his eyes rolling back. 

 

"Oooh... Gumball, don't stop..."

 

"Like I said, I was pretty backed up... I think we'll be here for a while." 

 

Gumball's poop slid down his dad's dick, relaxing as Richard picked him up and laid him on his belly. They looked each other in the eyes as Gumball kept pushing out massive dumps for his dad's cock to swallow. Then, they kissed as Gumball felt his shit plop down into Richard's toilet, releasing another wet, raunchy fart for them to enjoy. Richard then turned Gumball around, eating his son's ass. Gumball blushed hard. 

 

"D- daaad!"

 

He passed a large, loud fart in Richard's mouth, feeling relieved as Richard's tongue lapped up his gassy, shitty hole while he farted. He pushed again, a shit thicker than the one he dropped in Richard's dick inching from his hole. Thankfully,  it wasn't very long, and in a few seconds it dropped off in Richard's mouth. Unexpectedly, Richard turned him once more, then locked him in a kiss. In a filthy snowball, the two kissed each other, their tongues dancing around the fat turd, each sucking on the juicy log of waste. Richard bit off his end, as Gumball did his. They stared at each other lovingly while they ate up and gulped down Gumball's delicious snack. 

 

"Thanks, Gumball," Richard said. 

 

"Heh... Thank you, too, dad. I should let you get back to your nap." 

 

"Sure, but do you wanna nap with me?"

 

"Eh... Sure thing, dad."

 

Richard laid down, Gumball's dump still poking from his dick, his balls throbbing from being filled with his son's poop. He sat Gumball down on his face, Gumball himself laying on his dad's belly. Gumball giggled as he settled his butt on his dad's face. 

 

"You sure you wanna sleep like that? It might be a stinky, even shitty experience~"

 

"Shitty is what I want, Gumball!"

 

Richard kissed Gumball's asshole, Gumball kissing back with a wet blast of gas that Richard happily swallowed. 

 

"Love ya, dad."

 

"i love you too, Gumball."

 

The pair soon drifted off to sleep, Gumball occasionally farting and shitting on Richard's eager face as he slept.
