Nasty was off to visit the little raccoon Garuo’s house once again but this time was going to be a little bit different thanks to Izumy the otter. Izumy was Garuo’s daddy and he had made up a very special potion that was going to be very important in today’s play time. 
So once Nasty arrived of course the little three year old Garuo came running out and gave Nasty Donkey a great big hug, squishing his face to his chest as Nasty picked him up and hugged him. 
Izumy greeted him at the door with a hug too and then they sat around talking for a bit. Nasty was here to babysit Garuo for a time so before Izumy left, the otter handed him the potion and winked at him before heading off. 
‘’What’s that?’’ Little Garuo asked.
‘’Oh this? Well your daddy made it for me, it’s temporary but watch this.’’ Nasty Donkey said.

Nasty slowly started drinking the drink, it tasted better then he thought it would that’s for sure being some strange potion after all. After finishing the drink his body started changing right in front of Garuo’s little eyes.
He was shrinking down but not turning into a micro, no he was de-aging and turning into a foal (a baby donkey) until finally he was around the same age and height as Garuo. 
Still quite chunky and round though compared to him. Garuo squeaked in utter joy and pounced Nasty, making him fall to the ground as they cuddled up against each other, giggling and playing around.
‘’You’re so cute!’’ Garuo said.
Nasty blushed as he got up and looked at himself, admiring his little cub like dick and balls and his still fat cub butt. Him and Garuo hugged up again, it was really quite cute.
After a while they found themselves playing some fun little board games, like poop and ladders. It was just as gross and weird as it sounds, they got out the board game and then they pooped out some disgusting shit logs over the board where the snakes were. 
So instead of dealing with snakes, when they landed on the poop they had to eat it all in one piece and then shit out another log on to the ‘snake’ for the next person. It was quite fun for them but of course rather disgusting, just how they liked it. 
They did some finger painting with their poop too. Garuo was laying on his belly with his butt up in the air while Nasty would finger his ass, pushing one of his little fingers into Garuo’s butt hole, making the young boy moan in pleasure.
 He would get his finger smothered in cub shit and then spread it over the boy’s butt, making big smiling faces on his butt cheeks, at one point he put eyes up above his cheeks so that when he spread his ass, the hole was like a mouth opening up looking like it had been eating shit, it was quite hot.
Garuo then did much the same, fingering Nasty’s ass and then rubbing the shit in all over Nasty’s pudgy cub belly, both of them giggling as it happened. In the end Garuo had poop all over his butt cheeks and Nasty had some all over his belly.
After finger painting they played a game of catch, but not your ordinary game of catch. Nasty donkey pushed out a large log of shit, bigger then what cubs should be able to poop out.
With that large piece of poop they threw it around like a ball, giggling as they did so. Now and then it would hit their faces, marking their fur brown as it did so, not that they cared they were having so much fun.
After they were done playing around they shared the poop, each one taking a side of it in their mouth and meeting in the middle, kissing with the shit in their mouths, chewing and swallowing while making out.
As they started kissing, their tongues were probing their mouths, licking and drooling down their chins. Their little cock’s getting harder while they pressed up together, hugging and kissing roughly and passionately. 

They were getting really into it and getting very needy, especially after all the poop play. So soon enough Nasty was on all fours with his butt wiggling and jiggling as Garuo came over and pressed his little dick up against his butt, right between his thick butt cheeks. 
It felt so warm and amazing, it was so tight and felt so good around his cock.  He started humping inside Nasty’s rump and the donkey being this nasty little foal, started pooping as his butt was being humped, pushing out soft shit over the boy’s cock and balls while little Garuo moaned out in pleasure. He gripped Nasty’s butt, laying over his back as he thrust into him, panting and moaning and so was Nasty. 
He reached down and was stroking his little donkey dick, moaning loudly, pushing his butt back to get all of Garuo’s dick in him as his balls slapped against his ass cheeks.
Little Garuo was gripping his butt cheeks so hard, it felt just so good he had to keep on thrusting and pushing his cock in as deep as it could go, he looked down to see his cock disappear into that poopy butt hole. It was an amazing sight the way it sunk in and then hearing Nasty moan from how big it felt now on his tiny foul form. In no time Garuo released his seed into the dirty donkey butt, filling him up with raccoon cub cum.
After that Nasty fucked Garuo, the little cub laid out on his back with his legs up in the air while Nasty laid over the top of him and sunk his cock inside him. Nasty had cum seeping out his butt hole as he humped the little cub, Little Garuo moaning in pleasure so much so he was worried the neighbours would hear, so he pressed his lips firmly to him, making out with him as he humped his butt.  
Even though the neighbours loved the same kind of stuff but it was just the polite thing to do. Nasty could feel the shit within little Garuo coating around his big cub cock, his dick throbbing inside his butt hole. 
Garuo had to admit, his dick felt much better when he was bigger, because he was naughty like that, but it still felt amazing having a cub dick inside him either way. Though that meant he could be a little bit more rougher then, though still very loving, giving his hole a pleasurable pounding until he was cumming into that yummy butt.
Soon after Nasty was sitting on Garuo’s face pushing out hot messy poop over the top of his face but especially into his open mouth, also some of his cum was mixed with the poop making it even more tasty. Nasty himself had his muzzle under little Garuo’s ball sack and was eating out his ass as well. 
His tongue slurping all over the butt hole as Garuo pooped into his mouth.
They were in the classic sixty nine positions but eating out each other’s asses and shitting, feeding the other. 
Little Garuo had his mouth opened up wide and pressed against the butt hole, eating the shit right from the source until his cheeks were bulging outward. He was so happy, chewing and swallowing the donkey poop down into his belly, nasty eating Garuo’s poop just as much. The little one had a lot of poop inside him and it just kept on coming. Though Nasty was much smaller his appetite was no different, he could eat as much poop as he wanted. He kept on eating and so did Garuo until their bellies were full of hot messy, stinky poop all for them to poop out later.

Izumy arrived home a good few hours later, he could definitely smell what the cubs had been doing, even seeing some of the mess around the living room, he just giggled. He then made his way around the house to find where the cub’s were at. He went into Garuo’s room and smiled, Nasty and Garuo were cuddling on the bed and had fallen asleep. Nasty was still a young foul making it so much cuter. Izumy slowly and silently came over and pet little Garuo’s hair softly, smiling down and giving him a soft kiss on the cheek. At the same time Nasty slowly started growing back to his full size while still cuddling up to Garuo.
