One day in a small cabin in Station Square, a young female human was kneeling down on her bathroom floor. She was smiling proudly as she was observing a little hedgehoglet who sat on his potty chair. 

The little hedgehog had blue fur, green eyes and fluffy tanned chest and arms. His name was Sonic and he had a big smile on his face and it was time once again for him to use his potty chair.

"How are you doing, sweetie?"

Sonic looks up at the human, named Lilly, and smiles as he waits to relieve himself. He had his hands on either side of his chair and his pull-ups were down by his ankles.

"Me owk, mama! But it twaking a while to cwome out..."

"Don't worry, sweetie, it'll come out eventually. Let me see if I can help you out though..."

Lilly gently begins to rub the hedgehoglet's back in order to try and stimulate his bladder and bowels. Sonic closes his eyes and soon smiles as a few seconds later, a loud hissing sound was heard, echoing through the bathroom. The little hedgehoglet looks between his legs and wags his tail as he notices his willy shooting out a stream of yellow liquid onto the splash guard.

"Good job, sweetheart! You're doing really well with your potty training!"

Sonic giggles as the young human leans over and kisses his muzzle. He feels his cheeks warm up a bit and rubs his nose with a finger.

"It was nwuttin, mama..."

Lilly giggles from her little boy's modesty and soon looks down inside the potty, making sure he was doing okay. She giggles a bit as she notices his willy continuing to shoot out a big stream.

"Goodness, I think I might have to give you less juice!"

Sonic giggles and nods as his stream begins to die down a bit. He soon stops completely and lets out a small sigh of relief. Lilly was about to help Sonic to his feet until she notices Sonic scrunching up his face a bit and clenching his fists.

"Need a poo as well, sweetie?"

The little hedgehoglet nods as he attempts to push on his bowels. Lilly rubs his back once again and smiles as she hears some plopping sounds coming from Sonic's potty chair. After a few minutes, the blue blur sighs in relief and reaches his arms up at Lilly. The young human lifts Sonic off his chair before putting him on the ground in front of it.

"Good boy!"

Sonic stands proudly as Lilly grabs a packet of baby wipes. She takes one out and begins to clean up his willy with it. Sonic giggles and wriggles around from the sensation.

"Mama, that twickles!"

Lilly giggles as she puts the wipe into his potty chair before grabbing another one. She then slightly bends Sonic over and he makes a confused expression.

"Sorry sweetie... just need to wipe your bottom."

"Ah, owk mama..."

Sonic giggles a bit as Lilly proceeds to wipe his bottom. She then puts the wipe into the potty and stands up, beginning to empty out the chair.

"You did really well, sweetie. You went wee-wee and poopy all by yourself!"

The little hedgehoglet wags his tail as he walks over to the sink before climbing up onto his stool. Lilly flushes the toilet and stands up before walking over to the sink and helping Sonic to wash his hands.

"Sweetie, I have a new trick to teach you the next time you need to pee."

Sonic grabs the towel and starts to dry his hands off with it before hanging it back up again.

"Owk mama, what kwind of twick?"

Lilly smiles as she walks over to the toilet and pulls down her trousers and underwear before sitting down onto it. She reaches down and pats the floor with her hand.

"Alright sweetie, sit in front of me. I'll explain..."

Sonic nods and sits down in front of her, looking up at she begins to pee into the toilet bowl. Lilly smiles a bit as she uses a finger to point to Sonic's willy.

"You see... you're a boy hedgehog which means you have a willy. And you can use your willy in order to mark things with your wee-wee."

Sonic puts a finger to chin as he looks down at his willy.

"Mwark thwings?"

"Well, you know when you go for a wee-wee in your potty and you make a big puddle?"

Sonic nods, getting more interested in the conversation.

"Well, when you go wee-wee standing up, you leave a mark on the object that you're going wee-wee on. What I am going to do is teach you how to do it standing up. Then you go wee-wee on trees and bushes, you see?"

Sonic wags his tail, excitedly.

"Weally? Me get to wee-wee on trees?"

"Of course! As a boy, it's your responsibility to leave wee-wee marks so that other males know that you've been here and know that a male already lives here."

Sonic smiles and nods his head.

"Me understand, mama! Bwut how do me go wee-wee on trees?"

Lilly smiles as she reaches down to Sonic and gently wraps her fingers around his willy. Sonic blushes a bit and looks up at Lilly with a curious expression.

"You do this and you aim it at whatever you want to go wee-wee on. Kinda like a hosepipe, see?" 

Sonic nods and watches as Lilly lets go of his willy. He then reaches his hand down and uses his fingers to grip onto his willy too.

"Me hwold it like this, mama?"

Lilly giggles a bit as she finishes peeing.

"Yeah, that's right, sweetie. But wait until you need a wee-wee and then tell me so that you can practice weeing on things, okay? We'll start with your potty chair then move onto trees and walls."

Sonic stands up from his sitting position and giggles excitedly. 

"Me cwan't wait, mama!"

Lilly giggles again as she stands up from the toilet and grabs some toilet paper. She wipes her vagina clean before putting it into the toilet and flushing it. She washes her hands then takes Sonic's hand as she leads him downstairs. Sonic giggles as he still has his fingers wrapped around his willy.

Lilly leads Sonic to the kitchen and gets out his sippy cup from the cupboard.

"Would you like some juice, sweetie? It's quite warm out there and I don't want you to get dehydrated..."

Sonic nods as he sits at the table and continues to hold his willy.

"Ywes pwease, mama!"

Lilly looks back and smirks a bit as she notices that his hand was still around his willy.

"What are you doing, cheeky~? It's not time for a wee-wee yet, is it?"

Sonic giggles and makes an innocent expression as he lets go of his willy.

"Me nwot dwoing anything, mama..."

Lilly giggles as she walks over, handing Sonic his sippy cup. She ruffles his quills before pouring herself a glass of water.

"Cheeky boy~"

-----------------------------------

A few hours after Sonic drank the juice from his sippy-cup, he wriggles around in his sitting position and looks up at Lilly, hands between his legs. Lilly, who sat at the table, drinking another glass of water, notices Sonic and stands up.

"Wee-wee mama, I gwotta gwo!"

Lilly smiles as she takes Sonic's hand and pulls him up into a standing position. She then leads him upstairs to the bathroom and slides his potty chair closer.

"Ok sweetie, this is it... time to go wee-wee like a big boy!"

Sonic smiles a little as Lilly kneels down beside him and gently wraps her fingers around his willy. The blue blur blushes a bit but soon begins to relax as a stream of urine shoots out and hits the splash guard of the potty chair. He wags his tail and sighs in relief.

"Now, how about you give it a try?"

Sonic watches as Lilly lets go off his willy and soon begins to panic a bit as his stream splashes onto the bathroom floor, making a small puddle. He quickly moves his hands to it and holds onto it with his fingers, aiming it back into the chair, allowing it to spray all over the splash guard.

Lilly claps her hands and smiles widely.

"Good boy! Now you just need to shake yourself off..."

Sonic giggles as he soon finishes peeing and curiously shakes his willy, wondering if he did it right.

"Perfectly done, sweetie! You're ready to do it on trees now too!"

The little hedgehoglet squeals as his mother kisses his muzzle from behind, continiously. He giggles a bit as Lilly begins to clean up his willy with some toilet paper. She puts the paper in the toilet before flushing and washing her hands once again.

"You can go off and play now, sweetie. If you need to go wee-wee again, tell me and I'll take you outside to mark your first tree!"

Sonic wags his tail as he runs off downstairs to play with his toys. 

------------------------------

After a few hours of playing with his toys, Sonic soon feels the urge to pee once again. He stands up from the ground and puts his hands between his legs.

"Gwotta gwo wee-wee!"

He begins to run towards the stairs but soon feels his bladder unable to hold on much longer. The blue blur whimpers and lowers his ears as he looks around, trying to find something to wee onto. He notices the backdoor of the kitchen from a distance but whimpers more as he notices that it's closed, presumably locked.

Sonic takes another step but soon crosses his legs as he feels the need become stronger. He waddles over to a nearby plant pot and gets into position as he feels his bladder about to explode.
 
"It cwoming, it cwoming!"

The blue blur whimpers as he leans back and holds his willy, aiming it at the soil inside the plant pot. A few seconds pass by until Sonic sighs in relief, feeling his bladder release a thick yellow stream into the soil, soaking it.

"Ahh... dats bwetter."

Sonic wags his tail as he watches the direction of his stream. It splatters onto the soil and sprays off, hitting the side of the plant pot. Sonic whimpers a bit as the stream starts getting shorter and watches as it starts to dribble down the plant pot and onto the carpet, making a small stain.

"Sonic Maurice Hedgehog!! What do you think you're doing?!"

The little hedgehoglet squeaks and opens his eyes widely as he turns his head back, noticing Lilly stood behind him, her arms crossed and an angry expression on her face. Sonic whines and lowers his ears, sniffing a bit as he finishes urinating. He shakes his willy and turns around before putting his hands behind his back.

"Me sowwy mama... I weally nweeded to gwo bwut the bwackdwoor was closed!"

Lilly looks at him, sympathetically, before pulling him into a hug. She looks down as she notices a small pool of tears gathering in his eyes.

"It's alright, sweetpea... accidents happen. Besides, at least you've given the plant some water. It was quite thirsty..."

Sonic giggles a bit as he wipes his eyes with his hands and Lilly gently rubs his back before pulling away. 

"And it was my fault, sweetie. I'm sorry I didn't keep the backdoor unlocked. But I'll tell you what, I'll open it now and you can go outside and have a wee-wee wherever you want, okay?" 

Sonic smiles and runs towards the door excitedly as Lilly catches up to him and unlocks it. She opens the door and watches as the blue blur giggles, running towards a nearby tree. He looks back at Lilly before hiding behind it.

Lilly smirks a bit, thinking that he was playing hide and seek.

"Oh no! Where has Sonic gone~?"

She hears a little giggling sound coming from the tree and sneaks up to the tree before peeking behind it.

"Gotch-- oh, Sonic..."

The blue blur blushes as he looks up at Lilly, smiling nervously. He was squatting down, having a poo onto the grass. He continues to poo and looks away as Lilly squats down beside him, giggling a bit.

"You seem to be taking the marking business quite seriously, sweetie..."

Sonic whines but soon feels Lilly kissing his cheek. He soon finishes pooing and Lilly helps him to stand up before using a wipe to clean up his bottom. 

"You're a marking expert now, sweetie!"
