One day in Mobius, a young male hedgehog, named Sonic, yawns as he stretches and sits up in his bed. He rubs his eyes with his hands before getting up and fixing his bed. He walks over to his window and opens his curtains, smiling from the bright sunlight shining on him.

"Mmm, what a nice day..."

He sighs and soon looks down at himself. He yelps, noticing that his penis was fully erect and on show to any onlookers who happened to be outside of the window. 

(Luckily for Sonic, he lived in a forest area so not many people tend to walk around there!) 

He soon covers himself up and runs back over to his bed, sitting down on it. He stares down at his erect penis and gasps as he gently pokes it. Being a young teenager, Sonic had no idea about the certain sexual feelings that he would start to get whilst becoming an adult.

He lowers his ears, nervously, as he simply stares down in confusion at his rock-hard member.

"W-what is... when did this even happen?"

After a few minutes of staring down at it, he shakes his head before walking over to his computer. He sits at the chair and logs on, quickly, before starting to search.

"I gotta look this up... this might be a medical problem!"

He nervously types in "penis feels hard for no reason" into the search engine and starts to read up, specifically about "sexual arousal" and "sexual dreams". He blushes furiously as he reads up on the research. 

"W-what... how did they know that I have THOSE kind of dreams about Kira?!"

He soon covers his mouth, realising that he said it quite loudly. He continues to research and soon sits back in his chair, becoming confused about all of the information given. He looks down at his penis, noticing that it had now gone back to normal.

"I... I don't understand any of this. Why is my penis back to normal now?! I'm so confused!"

He puts his head into his hands and sighs frustratedly before looking over to his bedroom door. He soon gets an idea and stands up before putting on a pair of boxer shorts.  

"Of course... maybe mom knows about this. I better go talk to her..."

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

A humming sound can be heard as a young female human is having a shower. She continues to hum to herself as she soon rinses herself off and turns the dials on the shower. The shower stops running and she steps out of the cubicle.

The young human, named Lilly, reaches over and grabs a towel before starting to dry herself off. 

"Phew, I really needed that shower..."

She soon puts the towel over her shoulder and walks into her bedroom, completely naked. She hums again as she uses the towel to dry off her hair. 

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

Sonic, who was now in the hallway, tiptoes towards Lilly's room and peeks around the doorway. He soon opens his eyes widely and blushes a vibrant red as he sees Lilly drying off her hair. Her naked body now being completely visible to him.

Sonic gulps as he motions his eyes down her body. He notices her curves and relatively large breasts with equally large nipples. He unknowingly starts to wag his tail as he motions his eyes down to her brown-haired vagina. Sonic was unknowingly starting to go into 'heat'.

Once Lilly had finished drying off her hair she puts the towel down onto the bed and turns to see Sonic peeking in through the doorway. She smiles as she notices Sonic pull his head back slightly, trying to hide from her.

Lilly giggles and puts her hands on her waist, shamelessly revealing her fully naked body to the young hedgehog.

"Come on out, sweetie... I know you're there~"

Sonic peeks around the door again and slowly walks inside her bedroom, his hands behind his back. There was a noticable blush on his muzzle as he sits down on Lilly's bed.

Lilly looks over to him, worriedly and gently places a hand on his head. Sonic blushes more as he unknowingly looks down at her breasts. He then looks away and subtly puts a hand over the crotch of his boxers, feeling his penis about to go hard once again.

"Are you ok, sweetie? You look a little flustered..."

Sonic turns back around, only to have Lilly gently cuddle his head into her chest in a comforting way. He blushes brighter and closes his eyes, trying not to look at her breasts.

"N-not really, mom... I... I wanted to ask you about something."

Lilly pulls away and looks down at him, smiling.

"Oh? Then ask away, sweetie..."

"Well I woke up this morning and I... my--"

Before Sonic could finish his sentence, he grits his teeth and keeps his hand over his crotch. As to be expected, his penis had gone rock-hard once again. Lilly noticed his strange behaviour and notices that his hand was over his crotch.

"Do you need to go for a wee, honey?"

Sonic looks down at his crotch before turning his lower body away from him, nervously, his hand still over his crotch.

"H-huh? Oh... n-no. Eheh..."

Lilly gives Sonic a curious look and soon places a hand on top of his. Sonic squeaks a little as he looks down. His eyes, once again, motion towards Lilly's vagina and he closes his eyes tightly. Lilly feels Sonic's hand shaking nervously and gives him a sympathetic look.

"Are you sure you're okay, honey? You seem really nervous about something..."

Sonic continues to look away, keeping his eyes and lips tightly shut. Lilly removes her hand from his and gently puts them on Sonic's cheeks. She feels the heat coming off them and looks behind him, noticing his tail wagging slightly.

She soon smiles and wraps an arm around him, holding him close to her. Sonic curiously opens his eyes and looks up at Lilly.

"I think I see what's going on, sweetie..."

"Y-you do?"

"Yes. Are you having certain... strange feelings... in your lower region?"

Sonic blushes wildly as he looks down at his crotch and twiddles his fingers.

"M-maybe..."

Lilly smiles as she notices that he's acting very shyly and not looking at her directly. She gets up and soon grabs a big towel before wrapping it around her chest. She then sits back down next to Sonic and wraps her arm around him once again.

"I'm sorry darling... I have a feeling that this was my fault."

Sonic soon looks up at Lilly with a confused expression.

"W-what do you mean?"

"Your... lower region, it's... gone hard, hasn't it?"

Sonic soon gives up completely and puts his hands over his face. 

"Alright! It's true, my penis is hard, ok?! B-but I don't know why!"

Lilly soon gives a sympathetic look as she hears Sonic sobbing a little. She places a hand on his shoulder and gently pulls him into an embrace. Sonic continues to sob into his hands as Lilly kisses his head and gently rubs his back.

"Shh... it's ok, sweetheart."

Sonic soon raises his head and sniffs as he shamelessly pulls down his boxers and reveals his rock-hard penis to Lilly. He points down at it before putting his arms behind him.

"W-why is it like this, mom?" W-why?"

Lilly puts a hand over her mouth, blushing a little from Sonic's display. She looks down at his penis, briefly, before putting a hand on top of his. She pulls him into another embrace and smiles a little.

"There could be several reasons why, sweetheart. But they're all completely natural... and you shouldn't be ashamed of it."

Sonic sniffs as he looks up at Lilly with tear-filled eyes. 

"R-really?"

Lilly smiles as she reaches over and takes a tissue. She uses it to dry Sonic's eyes before putting it back down onto the bed.

"Yes. The penis can be quite a complicated thing to work out... especially for a boy of your age. But one of the main reasons why you're having this reaction is to do with girls... or boys."

"B-boys?"

"Well... I mean... if you 'go that way'."

"Oh..."

Sonic, who understood what that meant, blushes and shakes his head.

"N-no, I'm straight, mom..."

"I had a feeling. But it's ok by me if you 'go that way' too... I fully support it."

Sonic smiles a little as he sniffs.

"T-thanks mom. But I'm definitely straight..."

Lilly smiles back and continues to cuddle him.

"Well, in that case, it'll be all about girls. You see, when you get to a certain age, your penis will often do strange things... particularly around a girl that you really like or just around girls who attract you."  

Sonic nods, understanding what she's saying.

"These feelings come naturally to both humans and mobians and they help males and females to find a mate. Now, a mate is a girl or a boy that you feel physically and mentally attracted to. Most of the time, the mate will be for life... but of course, sometimes it doesn't last forever."

"It... it doesn't?"

"Well... there are unfortunate cases of couples having a divorce or because they are uncompatible as well as-- well I'll explain when you're older. The school definitely will either way though."

After about 20 minutes of talking, Sonic soon fully understands the 'feelings' that he's having and nods his head as he stands up.

"I... I think I understand now, mom."

Lilly smiles and nods as she watches Sonic pull his boxers back up.

"I know it's a difficult thing to go through, sweetie, but don't worry, you're not the only one... I went through it many years ago but, in a more different way, of course..."

Sonic gives Lilly a confused look.

"Really? Girls go through it too? But girls don't have a--"

"Well, we feel it in our vaginas... and our breasts. But we don't 'go hard' as such... rather we get sexual feelings over boys that we like."

"Huh... that's interesting."

Sonic smiles as he gives Lilly a big hug as well as kissing her cheek.

"Thanks mom... I really owe you. I... do have another thing to say though."

"Yes, honey?"

Sonic shyly puts his hands behind his back before looking shyly down at his feet.

"Well... earlier when I was covering myself, I... for some reason I... went hard because of... well--"

"Because of me?"

Sonic's face lights up again as he looks over to Lilly, who had taken off the towel and was starting to get dressed.

"W-what? How did you--?"

Lilly giggles a little as she pulls on her underwear and trousers.

"Isn't it obvious? It's because you've never seen a naked human before... your emotions must have been all over the place. I apologise for doing that to you, darling."

"B-but... surely I must have seen you naked before though..."

"Well, to tell the truth, you've seen me naked a lot of times. But you were only a baby back then so you wouldn't have remembered. We used to bathe together when you were really young and we used to go to the toilet together whenever we were out in public, of course."

Sonic gives a curious look and Lilly giggles again.

"I mean... whenever you needed a wee and we were shopping, we used to go into the same toilet cubicle. I would make sure that you had a wee in the toilet and then I would often need a wee too. So then I would have a wee and you would watch me. That's what I meant by 'go to the toilet together'."

"Oh... heh, silly me."

Sonic chuckles a little and puts a hand behind his head. Lilly giggles once again as she finishes dressing her lower half. Sonic soon walks over and cutely lays down in Lilly's lap. Lilly smirks down at him.

"Trying to act all cute, are we~?"

"Maybe~"

"Well, it's working~!"

Lilly soon blows a raspberry on Sonic's tummy and the young male laughs and kicks his feet.

"N-no mom! I'm t-ticklish!"


Lilly smirks a little as she soon stops blowing raspberries. She looks down at him and cuddles him close to her chest. Sonic, who no longer felt embarrassed, purrs as he nuzzles his head into her.

Lilly smiles down at him and soon giggles from a thought.

"You know... this reminds me of when you were a toddler and needed cheering up. You used to lay in my lap then snuggle into my chest and then-- ah, well..."

Sonic remembers back and blushes a little.

"D-drink your milk?"

"Yeah... I know that breastfeeding is only meant for newborns but I guess I didn't want to give up the habit until later on. It was good for helping us bond... still... I never really wanted to give it up."

Sonic lowers his ears a little as he notices Lilly sighing sadly. He soon blushes as his tummy rumbles and he looks over at Lilly's breasts before looking up at her.

"M-mom? This is gonna sound really weird but... can I... feed off you... please?"

Lilly blushes a little from the request but smiles down at him and gently rubs his head.

"Of course you can, sweetheart. This milk is only for you anyway..."

Sonic smiles and wags his tail as he soon gets picked up by Lilly. The young human holds Sonic close to her chest and smiles as he starts to suckle from her, as if by instinct.

Lilly sighs happily and looks down as Sonic soon pulls away and speaks.

"Love you, mom."

The young human kisses Sonic's head as she continues to hold him close.

"Love you too, my little BlueMuffin."
