"It... it's kwinda... embwarrasing."

"Aww, don't be shy, son... you can ask me anything."

Samuel looks down at his penis before pointing up at his father's.

"Well um... why dwoes my willy and your willy lwook dwifferent?"

The blue blur blushes brightly as he looks down at his penis. 

"Well um... you see, son... all willies are different. Plus it all depends on age too."

Samuel looks curiously at his own penis before looking up at Sonic's once again.

"Owh... is dat why mwine is skin cwoloured and yours is blue?"

"Y-yeah... when you get older, your willy gets covered in fur. In my case, blue..."

Samuel soon lowers his ears as he notices the clear size difference.

"Bwut dwaddy... why is mwine so smwall?"

"That's because you're still young, Sammy. Your willy will grow as you get older... it'll be as big as mine, eventually."

Samuel smiles and wags his tail.

"Weally?"

Sonic chuckles as he ruffles Samuel's hair.

"You bet, bud. Oh by the way, it's always good to end your pee with some spurts..."

Samuel nods and soon watches as his stream dies down. He pushes hard and smiles widely as his urine gushes out and hits the tree, rapidly increasing flow. Samuel, nor Sonic, even cared that a lot of it was dribbling down onto his shoe.

Sonic chuckles as he notices Samuel's pleasure-filled face but soon gasps a little as he feels something odd. The little boy's penis had gone erect from the force of his urine!

The blue blur blushes a little from the odd occurance but soon loosens his grip on Samuel's penis. He watches as his little boy sticks his tongue out and releases 5 large spurts of urine. The little boy soon pants a little and looks down at his penis before seeing drops of urine drip onto his shoe.

Samuel sighs and smiles up at Sonic, wagging his tail and giggling. Sonic looks at the stain on the tree and looks down at Sammy.

"Whoa, you sure needed to tinkle, didn't ya?"

Samuel giggles and looks down as Sonic lets go of his penis.

"Me hwad a lwot to dwink, dwaddy..."

Sonic chuckles and ruffles his hair.

"Ah I almost forgot, son. You have to shake when you're done..."

Samuel looks up with a confused expression.

"Me dwon't understand, dwaddy."

The blue blur blushes and gently grabs Samuel's penis before shaking it for him. The little hedgehoglet looks down, confused before looking back up at Sonic.

"Like that..."

Samuel smiles up at him and soon shakes it himself before putting his hands behind his back.

"Me dwid gwood, dwaddy?"

Sonic smiles and gives a thumbs up before picking him up and bouncing him into the air.

"You sure did! You're such a good boy!"

Samuel squeals and claps his hands as Sonic lifts him above his head. The little hedgehoglet soon looks down and blushes as he notices that his penis is in front of his father's face.

Sonic blushes a little and soon chuckles as he notices Samuel attempting to cover up his penis. Sonic chuckles before putting him down and picking up his underwear.

"Silly Sammy. Now, let's get your willy covered up..."

Samuel pouts and crosses his arms.

"Aw... bwut me wike showing my willy, dwaddy."

Sonic chuckles as he helps Samuel put his underwear back on.

"I admire your courage, Sammy but your willy isn't something that everyone should see ALL of the time..."

Samuel lowers his ears as he looks down at his feet.

"Ywes dwaddy..."

Sonic lowers his ears before kneeling down and gently placing a hand on his shoulder.

"Don't worry son... when you're at home, you can show off your willy as much as you want. Just as long as you don't go wee-wee everywhere, of course..."

Samuel giggles and makes an innocent expression as he pulls on his shorts.

"Me won't dwaddy, me pwomise."

Sonic smirks and ruffles his hair.

"Ah, but you remember the last time, don't you? You went wee-wee all over the living room curtains..."

The little hedgehoglet blushes and looks away.

"Me sowwy dwaddy... he weally hadda gwo and my pwotty wasn't nearby."

Sonic chuckles.

"And the time you went wee-wee in the plant pot?"

"Me fought plants wiked water..."

Sonic laughs and picks up Samuel before kissing his cheek.

"You remind me of myself when I was your age. Mom told me that I used to have a wee-wee wherever I was!"

Samuel giggles and sucks his thumb as he nuzzles his head into his father's chest.

"Now, let's go back to mommy."

The little hedgehoglet nods as he continues to nuzzle into Sonic's chest.
