One day, in the Australian outback, a 4 year old thylacine, named Oliver, tiptoed around his home, as he attempted to escape and go outside for a wonder.

"Nate better be waiting outside like we planned..." 

The little Thylacine quickly scurried out the door, just before his father turned to face him and let out a sigh of relief as he noticed his best friend waiting for him nearby.

He greeted him happily and gave him a hug as his tail wagged.

"Where did ya wanna go today, Nate?"

Nathan jumped a little from the hug but soon returned it before smiling shyly in his direction. 

"H-Hi, Ollie... I'm not sure, did you have anywhere planned?" 

Oliver leaned against a nearby wall as he curiously looked back at his father, who was talking with his brother Sly.

"Well, there are these huge rocks that I found down past the river. I thought maybe we could climb on them... you in?"

Nathan looked back to Ollie with a smile as he nodded his head. 

"That sounds like fun... I'm in~!"

"Alright, follow me!" 

Nate soon followed behind Ollie as he ran off towards the river.

[b]Meanwhile...[/b]

In Ollie's home, both Ty and Sly were chatting to each other about their most recent adventures, when suddenly, Sly turned to the window and stood up as he noticed Ollie running off towards the river with Nate following behind him.

"Sorry to interrupt ya, bro, but isn't that Ollie over there going with Nate towards the river..?"

Ty got out of his seat and walked over to Sly and stood next to him as he looked out of the window and shook his head with a small sigh. 

"Ollie, you lil' troublemaker. Come on, Sly, we better follow 'em in case they come across any of Cass' goons."

"Good idea." 

Sly soon followed behind Ty as they walked out of the house and soon began to follow their sons to the river. 

[b]Meanwhile, with the kids...[/b]

Whilst Sly and Ty were following their sons, they soon noticed that both Ollie and Nate had made their way to the rocks and were looking up at them, curiously. 

"Hah! We made it!"

Ollie excitedly crawled onto the rocks as he looked back at Nate.

"Hey, you wanna climb all the way to the top?"

Nathan soon looked to the top of the rocks and gulped slightly. 

"I-I'm not so good at climbing... but I'll give it a try." 

He nervously reached up to grab onto the rock above him, making sure to follow behind Ollie.

"Just keep on finding ledges that look like they're good to step on."

Ollie confidently jumped from rock to rock, holding on firmly as he climbed up.

Nate huffed as he followed behind at a much slower pace.

"No fair, Ollie... you're better at climbing than me!"

Ollie looked back at Nate with a guilty expression as he stopped and waited for Nate to catch up to him.

"Sorry, Nate... daddy's been teaching me a lot lately. But, don't worry, I'll teach you as well some time!"

After a few minutes, Ollie made it to the top of the rock and reached behind to pull Nate up. 

After pulling him up, Ollie jumped up and down in excitement and looked over the edge of the rock.

"Bonza! We're at the top!"

Nate smiled and wagged his tail excitedly as he joined Ollie with looking down the rock.

"Yeah, the view is really good from up here." 

As Nate turned to Ollie, he soon noticed that he was crossing his legs a little and looked at him with a confused expression. 

"Are you ok, Ollie? You're wriggling..."

A small blush soon appeared across Ollie's maw as he pressed his hands between his legs and smiled nervously in his direction.

"K-kinda... I just really need to find a dunny or something."

Noticing Ollie's desperation, Nate puts a finger on his chin and looked around, feeling worried as he doesn't see any dunnies around. 

Also starting to feel the call of nature needing to be answered, Nate soon also began to cross his legs and lowered his ears. 

"D-Doesn't look like there's any around here..."

Ollie soon noticed Nate's desperation and lowers his ears also.

"Wait, do you have to go too?"

Nate soon let out a small whimper as he wriggled around on the spot.

"Y-yes, I really need a wee-wee!"

The thylacines look around desperately and soon both notice a patch of dirt at the top of the rocks, underneath some trees and quickly hobbled their way over to it.

"I guess this is probably the only place to go up here..." 

As he approached the area, Ollie quickly began to drop his pants and stepped out of them before pulling his underwear down, leaving him completely bare below his waist. 

Facing partially in Nate's direction, Ollie aimed his little penis at the ground before looking back at him.

"Well, don't you have to go too?"

Nathan blushed at the sight of Ollie's wiener, but soon stood beside him as he looked around before pulling down his shorts and diaper and aiming his penis at the ground. 

"Y-yeah, I need to go pretty bad..." 

A few seconds soon pass by as Nathan pushes on his bladder and sighs in relief, watching as a thick stream shoots out of his penis and splashes onto the dirt below him, near his sandals. 

"Ahh...~"

Ollie soon let out a small giggle as he followed behind and urinated on to the dirt patch, leaving a puddle just next to Nate's.

"Ahhh, that hits the spot...~" 

As they continue to push on their bladders, the boys' tails began to wag and they giggle as they look at each other. 

Ollie soon looks down at Nathan's ankles and notices that there was a diaper in his shorts. 

"Hey, you still wear a diaper, mate?"

Nathan blushed as he looked at his diaper and then looked back at Ollie as he continued to pee around his feet. 

"Y-yeah... I kinda have accidents sometimes. Daddy says that I can wear them around until I need to tinkle or poop and then I find somewhere to do it or use the dunny once I've taken them off..."

"Oh, I see... that's kinda cute~" 

As the boys continued to urinate beside each other, their fathers, Sly and Ty, had caught up to where Nate and Ollie were and began to climb the same rocks that the boys took. 

"They climbed all the way to the top of these rocks..?"

Ty shook his head as he looked up at the top of the rocks. 

"Ollie, you lil' rascal. Come on, Sly... we better get up there and make sure they're ok." 

Ty began to climb one of the rocks as he looked down at Sly.

"Alright." 

Nathan felt his ear twitch as he heard a small rustling sound and lowered his ears a bit. 

"H-hey, Ollie... d-did you hear something?"

Ollie let out a small gulp as he looked back over his shoulder to where the noise was coming from.

"Y-yeah... you don't think it's a frill, d-do you?"

Nathan let out a small whimper as they both noticed a nearby bush rustling around and scooted over a bit closer to Ollie.
