The two friends arrive in a different part of the city, beginning to walk through the street.

"Beautiful, isn't it, little buddy?"

Asks Sonic, putting his hands behind his head as he walks through the bustling street.

Tails nods in response as he walks alongside his buddy, still holding the shopper bag. 

"Yeah, it's perfect!" 

Sonic chuckles as he takes another sip from his bottle.

He finishes his third bottle and lets out a huge belch before putting the can into Tails' shopper bag.

Tails puts his hands on his waist and gives Sonic a stern look 

"Sonic!"

"What?" 

Asks Sonic. Tails sighs and shakes his head. 

Sonic soon realises that he belched out loud and blushes a little before chuckling nervously.

"Sorry, buddy... just be thankful it didn't come out of the other end though."

The young fox giggles from his friend's joke and continues to walk alongside him. Sonic smirks and ruffles Tails' hair.

Tails nods and continues to walk beside Sonic through the crowds of the city. 

"Hey Tails, how about we go to the city park for a little relaxing break?" 

"Sure, let's go!"

They walk towards the park but the young fox soon notices his blue buddy gradually slowing down. 

Sonic lowers his ears and blushes a little as he looks up to Tails. 

"Sonic? Are you alright?"

The blue blur soon comes to a complete stop and squeezes his legs together, whimpering softly. 

Tails runs over to him and puts an arm on his shoulder as a bigger crowd starts to walk either side of them.

"Sonic! What's wrong?" 

Sonic replies in low voice. 

"Um...I...I gotta go..."

Tails gives him a curious look as he looks around at the people surrounding them. 

"Go where?"

Sonic grits his teeth as he squeezes his legs tighter and whispers. 

"Go as in REALLY REALLY badly! P-please little buddy, help me..."

Tails lowers his ears and looks at Sonic with a sympathetic expression.

"My bladder is full, I REALLY need to pee!" He whispers.

Tails soon looks around to find a place where Sonic can relieve his bladder but he notices that the crowd are still surrounding them and that there wasn't anywhere suitable to pee.

The young fox soon gets an idea as he looks inside his shopper bag. 

He takes out an empty bottle and holds it out to Sonic.

"Here, use this."

Sonic takes the bottle and opens his eyes widely, blushing brighter as he looks at the crowd around them.

"What?! I can't use this! There's loads of people around..."

Tails scratches his chin with one hand and looks behind him, noticing his tails wagging slightly. He smiles and points to them.

"Hey, why don't I cover you with my tails? That way you can pee and no-one will notice." 

The young hedgehog puts a hand behind his head and looks at Tails' tails before looking around again.

"I don't know, little buddy..."

Tails sighs a little and watches as Sonic starts to wriggle around, his bladder's need becoming much more great.

Sonic soon sighs too and positions himself so that he was stood behind Tails. He then watches as Tails wrapps his tails around Sonic's lower waist.

Sonic soon brings the bottle between his legs and looks down as his penis starts to emerge from his fur. 

He blushes and gulps nervously as the people walk past him. Tails smiles back at him. 

"Are you in position, Sonic?"

Sonic nods and waits for a few seconds before releasing a spurt of hot liquid. He gasps as he misses the bottle and accidentally splashes onto Tails' leg. He blushes and grits his teeth.

"Ah! I'm so sorry, little buddy!"

Tails looks down at the dripping warm liquid on his leg and blushes, feeling a little aroused by the warm feeling of Sonic's urine hitting his leg.

After properly aiming the tip of his penis into the bottle, Sonic half closes his eyes and sighs in relief, as a goofy expression is on his face. His urine gushes out of him at a quick speed and the sound quickly becomes evident to Tails.

Tails smirks a little as he feels Sonic leaning forwards and the bottle being pushed against his butt.

He soon hears the sound of his best friend's urine, shooting into the plastic bottle. He also feels the heat of the stream against his leg. 

Sonic's urine echoes loudly, but is luckily drowned out by the sound of the people talking as they walk past. 

He continues to sigh in ecstasy and wags his tail rapidly as his urine continues to shoot out. 

"Ahhh... this feels amazing... thanks, little buddy."

Tails giggles from his friend's relief and looks around as Sonic continues to urinate. 

The blue blur soon looks down at the bottle he was using and gulps, seeing that it was completely full.

He groans a little as he forces himself to stop urinating, causing his bladder to be in a small amount of pain.

"Uh... Tails? The bottle's full... but I still need to go!"

Tails nods and turns back as Sonic, who embarrassingly gives the full bottle to Tails. Tails soon screws on the lid of the bottle and puts it back in his shopper bag before taking out another empty bottle.

He open the bottle and hands it to Sonic who quickly takes it from him and puts the tip of his penis inside the top.

Sonic grits his teeth as he pushes on back on his bladder. 

Soon a thick light yellow stream gushes out and the blur sticks out his tongue, moaning loudly again.

Tails smiles as he hears his friend moaning. He soon looks down in the bag at the full bottle that Sonic had handed him earlier and looks at it, curiously.

The warm liquid inside the bottle was a clear yellow colour kind of like the colour of tea. He puts a hand on the bottle and soon feels the heat of the bottle. He gets aroused by the fact that it was his best friend's urine that had caused it. Tails smirks at the bottle before placing it back his shopper bag.

He then curiously looks back at Sonic, trying to catch a glimpse of his best friend, urinating. 

The blur had his eyes closed so it was Tails' chance to get the view he wanted.

The young fox smirks as he notices only a thick yellow stream shooting out and filling the second bottle. 

He moans a little as he feels his own penis starting to twitch in arousal from the view and the feeling of the warm bottle poking near his butt.

Tails feels his ears perk up to catch the gushing sound and moans as Sonic continues to release his golden liquid into the bottle.

Tails soon notices Sonic opening his eyes and quickly turns around.

The young hedgehog sighs in relief once again and shakes his penis, instinctively in order to get rid of the last drops of urine at the end of it. The drops land on Tails' tails and legs.

Sonic soon smiles and hands the second bottle to Tails and steps back as Tails moves his tails out of the way.

"Ahhhh... that was great, little buddy. Thanks for helping me out!"

Tails giggles and nods.

"No problem, Sonic!"

Tails looks down in amazement as he notices that Sonic had filled the second bottle up to about 3/4 of the bottle's capacity.

"Wow Sonic, you REALLY had to go!"

But Tails also notices that there was no lid to put on the bottle, because he acidentally throws it back in the bag when opens it.

The blue blur blushes and rubs his nose. 

"Hehe... well I didn't really have time to pee this morning because I was already late for meeting up with you and Knuckles."

Tails giggles again with the warm opened bottle in his hand and watches as Sonic walks beside him.

Sonic points at the bottle and bag. 

"I think we better get rid of those before anyone gets suspicious. Especially the second one without the lid." 

Sonic was about to take the bottle when Tails quickly pulls it away from him. 

Sonic looks at him confused. 

"Wait here, Sonic, I'll do it. Besides, I can fly which means I'll be able to find a bin faster from higher up." 

Sonic grins and winks as he gives Tails a thumbs up.

"Good thinking, little buddy!"

Tails soon nods as he whirls up his tails and starts to fly into the air. 

He looks around whilst in the air and soon notices a small area of the city where there weren't many people. 

There was also a usable trashcan which hadn't been filled.

The young fox lands and approaches the trashcan with Sonic's bottle of urine still warm and uncapped in his hand.

He motions his arm towards the bin but soon the odour of Sonic's urine fills his nostrils.

He slowly pulls his arm back and looks down at the bottle. 

Against the sun, his best friend's urine seemed to glisten.

It also had a very pungent yet sweet smell to it, very much like the smell of hot dogs.

The young fox looks around and soon brings the bottle up to his nose before inhaling deeply.

Tails smirks and feels his penis twitching once again from the inside of his shorts.

He notices a few people looking at him but to them the bottle simply looks like apple juice.

"Hmm... it kinda looks like apple juice... maybe I could--" 

Tails thought to himself.

The young fox looks around and soon shrugs before bringing the bottle up to his lips and taking a small sip of the liquid. 

The taste was like a broth, light salty tasty with a surprisingly sweet watery aftertaste.

Also the warming sensation on his tongue down to his throat was awesome, Tails was very much enjoying it.

He looks around once again and then continues to gulp down his best friend's golden juice, finding a new thirst for it.

As he drinks, Tails feels the warm tasty liquid going down his throat and eventually into his stomach.

Gulp after gulp, the bottle with the shining golden liquid was soon completely empty.

Tails licks his lips and throws away the empty bottle into the trashcan.

He then looks into his shopper bag, noticing that the second bottle was still warm in there. 

He picks it up and opens it, smelling the warm salty piss. He shrugs then starts to gulp it down once more.

The young fox blushes at the thought of his best friend holding his penis to his mouth and letting his urine flow into it.

Tails' penis once again starts twitching from the dirty thought, running through his mind, he is about to start masturbating with his free hand but he stops because he realises that a lot of people can see him.

Tails soon sighs contently, noticing that the second bottle was now empty too. 

He let's out a big belch and blushes as a nearby person gives him a stern look.

"Eheh... sorry." 

Feeling his new thirst impulse disappear, Tails throws the second bottle into the trashcan and turns to head back towards Sonic.

"Hmm... my breath tastes like pee. I better find somewhere to wash out my mouth."

Tails notices a water fountain nearby and smiles as he runs towards it.

He turns on the fountain and slurps some water before drying up his lips with an arm.

"Now I better head back to Sonic..." The young fox soon whirls up his tails once again and flies over to Sonic's position, waving as he slows down and drops to the ground. He notices his best friend crossing his arms and tapping his foot, impatiently.

"It's about time, little buddy... where were ya?" 

Tails puts a hand behind his head and blushes a little.

"Sorry Sonic... there were a lot of people around so I had to find somewhere else to get rid of them."

Sonic grins and winks at him.

"No problem, buddy. But, we better head towards the park."

Tails smiles and nods as he walks beside his best friend. 

He giggles from the naughty thing that he had done previously, licking his lips, as he rubs his now urine-filled belly.

Sonic gives him a curious look as he giggles, but soon shrugs it off before continuing to walk beside his little buddy.
