He moans a little as his penis soon appears from his fur. He waits until it was fully out and soon aims it with his thumb and first finger.

A few seconds later, a loud hissing sound can be heard. Boom Sonic smiles goofily and looks down at his urinating penis. He puts a hand on the tree trunk and watches as his urine stream gets thicker.

"Ahh yeah... I REALLY needed this."

Back over near the forest, Modern and Classic feel their ears perk up from the hissing sound. Classic stands up and points over to where the noise was coming from. Modern nods and gently pets his head before running over to the area.

"I think it's coming from here..."

Classic nods and soon hides behind Modern, getting afraid of the loud sound. He holds onto Modern's leg as they both walk over.

"It sounds like a snake..."

Classic lowers his ears and continues to walk behind Modern. The two soon peek around the corner and both blush at the sight.

Boom Sonic opens his eyes and looks over, noticing Modern and Classic looking at him. He gasps and blushes, attempting to cover up his lower area.

"Ah! W-what are you guys doing here?"

Modern looks away and blushes brightly.

"I... we were just... um... wondering what the noise was!"

Classic rapidly nods his head before turning away too.

Boom notices how embarrassed they were and smiles a little.

"It's ok, guys... I just really had to go and well... the tree was the only option."

Modern chuckles nervously and puts a hand behind his head.

"Eh heh... it's fine. W-we'll leave you to it."

Modern and Classic were both about to leave when suddenly Classic holds onto Modern's arm and lowers his ears. He wriggles around a little and points over to Boom Sonic.

"Hmm? You need to go too, Mini-Me?"

Classic Sonic nods his head and puts a hand between his legs. Modern soon smiles and leads Classic Sonic over, trying not to look at Boom Sonic's penis.

Boom Sonic soon looks over as he continues to urinate. He chuckles as he notices Modern holding Classic's hand. Classic blushes and soon lets go before running over next to Boom Sonic.

"Let me guess, you need a wee too?"

Classic Sonic blushes more and nods as he rubs his lower area. Modern soon notices that Classic's penis wasn't emerging and walks over before kneeling down.

"Is it not coming out?"

Classic shakes his head and lowers his ears. Modern soon starts to rub Classic's lower area, attempting to help him out. Classic blushes brightly and looks down as his penis starts to emerge from his fur.

Boom Sonic smirks a little as Classic Sonic's penis is sticking out from his lower area. 

"Wow... you're pretty big, little guy~"

Classic Sonic turns away a little and soon starts to urinate. His urinate stream soon dribbles onto his shoes and he starts to panic. Boom Sonic chuckles a little and reaches a hand down, gently grabbing onto Classic's penis.

"Allow me, little guy..."

Classic blushes and looks down as he feels Boom's hand grasping his penis. He watches as Boom lifts his hand and helps him to aim the stream onto the tree trunk.

"Better?"

Classic soon smiles a little and nods as he continues to urinate.

Modern smiles a little too but soon feels the urge to urinate as well. He puts a hand between his legs and grits his teeth, feeling his urge getting stronger as both Boom and Classic's streams splash onto the tree trunk.

((Modern was a bit different to Boom and Classic when it came to urinating. He was really shy about doing it in front of others, unlike Boom who would happily do it in public and Classic who would do it if he REALLY needed to...))

Boom and Classic both smile at each other as they continue to empty out their bladders. Modern soon attempts to sneak away but Boom soon looks over.

"Hey, are you ok?"

Modern jumps a little and blushes as both Boom and Classic look over towards his direction. Modern shyly looks at them, noticing them both still urinating. He tries not to look down at their penises and lowers his ears.

"I... I'm fine. I just need to... um..."

Classic and Boom both look at each other and soon smirk a little as they notice Modern crossing his legs a little.

"You need to wee too, don't you?"

Modern opens his eyes widely and looks away, feeling his urge getting greater. Boom soon notices Modern's legs shaking and points to a spot next to him.

"There's plenty of room here, pal..."

"N-no, you d-don't understand... I--"

Modern soon gasps as he feels his penis about to emerge! He whimpers and covers himself as he runs over to another tree. He's about to aim and urinate when suddenly a bird squawks. He yelps and runs back over to Boom and Classic's tree before blushing. He gasps and soon looks down as his penis emerges and urine shoots out, splashing onto the trunk. 

Modern moans loudly and puts his hand on the tree, feeling the intensity of his stream gush out of him.

Boom and Classic both look at each other, wide-eyed before looking back at Modern. 

Modern wags his tail and sticks out his tongue, gushing consistantly onto the trunk. A huge wave of pleasure overcomes the blue blur, forcing him to throw his head back in bliss.

"Ohhh baby... that's SO good."

Boom smirks at Modern's ability and looks down at Classic, who was now aiming with his own hand. Classic closes his eyes and wags his tail as his stream increases in speed.

After watching the two hedgehogs urinate with amazing ability, Boom Sonic soon blushes as he feels his penis go slightly erect. He grits his teeth and soon puts a hand on the tree, pushing hard on his bladder.

"Nghhh, come on..."

Modern and Classic both look over to Boom and soon both blush as they notice his erection. Modern smirks a little.

"Mmm... does weeing turn you on, big guy~?"

Boom opens his eyes widely and blushes from the comment. He looks down at his penis before looking over at Modern's. He smirks back, noticing Modern's stream splash all over Classic's shoes.

"That's for me to know and for you to find out, pal... though by the looks of it, it seems that YOU are the one who likes it~"

Modern looks down and notices that he's urinating all over Classic's shoe. Classic blushes a little but soon makes a laughing expression. Modern then smiles and giggles as he looks over to Boom Sonic. 

Modern looks down, noticing Boom Sonic's penis and soon smirks, starting to get a naughty idea.

"Ohh, my bladder is SO full~"

Boom looks over curiously as he hears Modern's comment. Modern soon smirks and turns to face Boom, who was standing next to him. He continues to urinate and puts his hands on his waist as his stream shoots all over Boom Sonic's leg.

Boom Sonic yelps and continues to urinate as he tries to move his leg away from Modern's stream.

"What the--?!"

Modern smiles and closes his eyes, wagging his tail as he continues to splash his hot liquid onto his older counterpart's leg. Classic Sonic wags his tail and smirks a little as he notices the display. Modern puts his arms behind his head and throws his head back.

"Ahh, yeah... that's the stuff~"

Boom Sonic blushes brighter but soon smirks before turning to face Modern. Modern gives him a curious look and then gasps as Boom aims his penis towards his chest.

"Mmm, let's see how YOU like it~"

Modern soon blushes and sticks his tongue out, feeling Boom Sonic's hot stream spraying all over his chest.

"Mm yeah... you like that, don't ya~?"

Modern smirks and soon looks down as Classic walks over. He walks between Boom and Modern and licks his lips, wanting them both to urinate on him. Modern and Boom look down at him before smirking at each other.

"Heh, it seems that our Mini-Me wants some too~"
