One day in Mobius, a young teenage male hedgehog smiles as he reads a book. He lowers his glasses in order to focus on an image.

"Interesting..."

This young teenager was the son of Sonic the Hedgehog. His name was Samuel and he was quite an intelligent boy. He can normally be seen wearing a pair of jeans, a red checked shirt and shoes which were quite similiar to his father's. Since he was relaxing today, Samuel wore only his glasses and jeans.

He sighs happily as he continues to read through his book but soon feels an odd sensation. He shrugs it off and continues to read.

Since Samuel was so engrossed into his book and didn't want to get up, he simply smiles as he starts to feel the call of nature in a need of answering. 

"Hmm, I think I need to take a whizz..." He thinks to himself.

The young male looks around and soon chuckles to himself as he opens his legs. He looks down at his bulge and waits for a few seconds before--

"Ahhhhh... yeah, that hits the spot~"

Samuel half closes his eyes and smiles goofily as his ears pick up on a slight hissing sound. He chuckles to himself and wags his tail as he feels his urine shooting out of his flopping penis. As he turns to another page of his book, he lifts his leg and has a peek inside his jeans. He smirks as he pulls back another layer underneath, revealing a diaper!

He soon looks inside his diaper and licks his lips from the sight of his urine stream getting thicker. He chuckles as he notices his penis shooting urine higher. He soon grunts as he pushes hard, causing his penis to spurt a rapid and thick stream of urine which shoots higher and comes out of the diaper.

He wags his tail happily and rips off his diaper before moving his still floppy penis over so that his stream sprays all over his bed cover. He chuckles to himself as his thick stream spurts out like a firehose and splatters onto the bed cover.

"Oops... ah well, my bed cover needed a wash anyway~"

Samuel smiles in pure bliss as he soon lays on his front. He sticks out his tongue as his urine continues to shoot out fast. He moans and slowly moves his crotch up and down on the bed, causing the stream to spurt all over and make a big puddle.

He looks into the air and moans as he feels his penis being smothered in his steaming juice.

"Ohhhhh god... I really wish I could spray my steaming juice all over something... or even someone~"

He ponders but soon gets an idea. Samuel hums to himself as he gets into an all-fours position. He smirks as he grabs the book he was reading and soon puts it underneath him, smirking cheekily. 

"Perfect~"

Within a couple of seconds, Samuel smiles and wags his tail as he hears a splashing and hissing sound. He sticks his tongue out as his penis twitches. 

He soon hums to himself as he lifts his leg, shooting a lightning-fast stream all over the book. He watches and smirks as it all gathers into a hot puddle and steam starts to appear from it.

"Ahhhh... now that's how to make a fire~"

The young hedgehog wags his tail and smiles proudly as he looks down at the now steaming and soaking wet book, which used to be a science one.

"Eh, I was never into chemistry~"

He chuckles at the mess he made and soon looks down at his pillow, which was completely dry before smirking.

"You may not be a girl but you're really gonna enjoy this~" 

Samuel smirks as he grabs his pillow and lays it vertically on his bed before opening the slit on the pillowcase. He then looks down at his still-flowing penis and sticks it into the hole. He smiles as he hears a splattering sound and closes his eyes, picturing himself urinating into a girl's pussy.

"Ahhh... yeah, you like that, don't ya babe~? Yeah, my steaming hot juice flowing into your pussy~" 

He pants and sticks his tongue out as his urine continues to flow, spurting and spraying in different directions.

All of a sudden, Samuel hears a thudding noise and gasps before looking down at his penis. He tries to pull it out but soon realises that he's trapped!

"Crap, dad's coming... come on bladder, please s-stop!"

Samuel gasps again as he feels his urine continue to shoot out. He whimpers as he tries to hold it in but soon lowers his ears as he can't hold it at all. He throws pillows all over his bed cover, trying to cover the mess he had made whilst using his long shirt to cover the pillow hewas urinating into.

He sweats heavily as he hears his father's footsteps getting louder and quickly hides the book and his diaper under the bed.  

"Hey, Sammy!"

"Dad."

Sonic gives a curious look as he notices Samuel's somewhat strange behaviour. He sits next to Samuel and puts a hand on his shoulder.

"Sammy? What's wrong, buddy?"

"N-nothing."

Sonic ponders and soon hears a hissing sound. He looks over to Samuel and notices a blush on his face. Samuel smiles innocently as he continues to spurt his juice into the pillow. Sonic gives him a curious look before sniffing the air.

"Phew, smells like urine in here... have you been weeing somewhere that you aren't supposed to, little buddy?"

Samuel blushes a little.

"Uh... n-no dad."

Sonic gives Samuel a serious look and soon notices Samuel sweating and gulping. He sits down on one of the cushions over the bed and soon picks one up, noticing the huge puddle on his cover. He gasps and looks back to Samuel.

"Have you been having accidents again, Sammy?"

Samuel blushes more and looks away, continuing to spurt urine into his pillowcase. 

"I... I... well... you see..."

Sonic soon smiles a little from his son's blushing muzzle and gently pulls Samuel into a cuddle.

"Hey, it's ok, little buddy. We all have accidents every now and then..."

Samuel smiles nervously as he looks up at Sonic, still spurting his juice.

"Thanks, dad."

Sonic smiles and ruffles his hair before noticing Samuel's hands covering his crotch. He reaches out and tries to pull his hands away but feels Samuel resisting.

"Sammy? What are you hiding?"

"N-nothing! J-just my willy, dad..."

Sonic gives him a curious look.

"You should be wearing your diaper... is there any reason why you're not?"

Samuel gulps again.

"I... I lost it!"

Samuel notices Sonic's ear perk up and lowers his ears, realising that he can hear him urinating.

"Then... what are you weeing into... or on?"

Samuel soon lowers his head, knowing that he can't win. He uncovers his hands and Sonic notices that Samuel's bottom half was fully uncovered and he had a pillow on his lap. 

"Sammy... are you... weeing in your pillow?"

The young hedgehog lowers his head more and covers his face. Sonic curiously opens the pillow and gasps as he sees his son's penis spurting urine inside and soaking the bottom of the case.

"Sammy..."

Samuel lowers his ears and sniffs, feeling tears come to his eyes.

"I'm sorry, p-papa... I didn't... I... didn't want you to... see."

Sonic gives a sympathetic look and gently pulls Samuel into a cuddle. Sammy looks back and soon wraps his arms around Sonic, cuddling back and sobbing softly. 

"Hey, it's alright. I know you have a bit of an incontinence problem... but it's for the best that you only go wee-wee in your diaper, ok?"

Samuel soon sniffs in embarrassment and nods. He and Sonic both look down into the pillowcase and watch as Samuel's stream spurts high into the air, followed by a pause... and then another spurt which lasts around 5 seconds. The two then watch as Samuel's penis twitches and goes hard.

Sonic blushes as he feels his own penis start to go hard. Turns out that he had got a bit turned on by his son's urine strength, rapid spurts and sudden erection.

"Wow... I didn't know you were aroused by that sort of thing, Sammy~"

Samuel blushes brighter and covers Sonic's mouth.

"Dad, shush! I don't want anyone else to know..."

Sonic smirks a little.

"Don't worry, pal... my lips are sealed. You know, me and your mother get turned on by wee-wee too~"

Samuel looks over at Sonic in shock.

"Y-you do?!"

"Yeah... we used it in all sorts of different ways but that's a story for another time. For now, just keep on weeing in your diaper, ok son?"

Samuel smirks as he takes his erected penis out of the pillowcase. Sonic blushes brighter as Samuel actively rubs it up and down in front of him, feeling horny for attention.

"Will do, dad~"

Sonic blushes brighter and soon feels his body heat up. He gives into temptation and soon sits down next to Samuel. Samuel wags his tail as Sonic smirks and reaches his hand over. The young male moans as Sonic gently grasps his son's penis. 

"Wow... you're really hard, aren't you son~?"

Samuel licks his lips as Sonic soon lets go of his penis. 

"So... weeing turns you on, dad~?"

Sonic smirks as he crawls over his son. He whispers.

"Sure does, Sammy~"

Samuel wags his tail as all of a sudden, his penis shoots a thick stream of urine up into the air. Sonic gasps as the urine splatters all over his chest before dripping down onto the bed. He smirks as Samuel sighs in relief and makes an innocent expression.

"Oopsie, guess I had to go potty again~"

"Good boy~"

Sonic smirks down at Samuel as he unbuckles his belt and lets his penis flop out of his fly. Samuel smirks at his father's penis size and soon moans as Sonic releases a thick, steaming stream of urine onto his penis. He moves it around, making sure to spray his steaming juice all over his son's balls.

Samuel moans and lays there, submissively.

"Mmmm... dad~"

Sonic smirks and wags his tail as his urine stream starts to die down. The two watch as Sonic's penis twitches and releases a large spurt onto Samuel's stomach. He licks his lips and watches as Sonic's penis soon starts to dribble. Sonic sighs in relief and smirks down at his son before kissing his cheek.

Samuel wags his tail and looks up at Sonic, feeling heated by the feeling of Sonic's hot liquid all over his balls.
 
"Mmmm, dad... please... let me be your urinal too~"

Sonic chuckles before kissing Samuel's cheek once again.

"Of course you can... now, let me teach you how to mark your territory, my son~"
