that day Aya and Saruto where going to the park so they miraculously survived, on the last of the mother breath, she plead Aya to take care of her son and the younger sister promised with teary face..

****

now the present, Aya was going home after a full day of teaching brats a subject they unusually hate "why do I need to learn math?! being a cool ninja doesn't involve that!" if she were given a ryo every time she heard that phrase , she can eats together with her nephew at 5 stars restaurant everyday!

"well not everyone can become ninja, so the rest of you who can't, please f**k off." she would say in a kind smile, it worked like charm, honestly she got used to Saruto maturity she forgot how entitled that snots can be, even when she decided to taught him earlier so he wouldn't have to take these classes with those brats, she thought he would at least complain, she that was normal as he, unlike these kids, doing hard work! even for age of 4 he trained albeit not tensely

so mark her surprised when she didn't heard complain a word, instead he thanked her for consideration and immediately agreed to her proposal, that day she made a beautiful smile that the kids she teaching might freak out as she never smiled like that, to them she is the numbered demon!

what was pleasant to her more that he took the information like a sponge, as if he learned it before! he made mistake here and there but those mistake where something like who took the material but never review it for a while

this made her raise an eyebrow, but then shurgged it off as coincidence, as she rarely got to see him do them again.

thinking about her elder sister's son made her subconsciously smile, for her, he is like unsolvable mystery, he wasn't like this, before he was 4 , he was like a normal child albeit quite silent and antisocial, she never thought it as problem as he was pretty young, and talking to strangers is embarrassment to him

but all change that day she went to a park to him, suddenly he wanted to be a ninja, while civilian isn't rare to them to become one, it isn't common, and she weird he might exhaust himself training, or worse get depressed when saying how talented the other kids, especially the clans one, like Uchiha for example

on that day also she met kushina and mikoto both coming with their daughters, she wasn't that close to mikoto but were on a good terms, but she was good friend with kushina because of what happened years ago, at first she tried to treatment formally, as one the 4th hokage widow and the second is the wife of Uchiha head

but on kushina's wilfulness, she relented and become to be casual with them, privately at least, but what made her smiles is that her nephew become very close with both of their daughter, she began to think he might to become quite the player, she then took upon herself to educate him probably lest he brake some maiden heart one day

and years moved like flowing river, as already 4 years, and her Saruto become bigger and stronger, he even was student of her friend's mikoto's son, who is famous jonin, she guessed that the teenage is quite jealous and wanted to test Saruto to check if he suitable for his sister, the thought made her giggle

she always like to tease him and Carry him around, the little monkey in her language, didn't particularly liked the carrying but never complain as he usually shake his face in her chest in effort of her to put him down, she never did tho to his frustration...or that's what she thought anyway...

while thinking about all of random things, she reached her house and upon entering she saw Saruto sitting on nearby couch

"I'm back~ Saru-chan~" Aya said pleasantly

"evening, Aya-nee" Saruto smiles in kind

"ara~ where is my coming hug~" she gives a pout which made Saruto smiles wryly and disappeared from her sight, second later he is hugging her like a monkey from the front

"fufufu, I never got bored the way you teleport infront me~ I never thought kushina-san would give you the the 4th hokage technique, you must be pretty close to her right~?" she caress his head affectionately

"what can I say, my charm is effective against milfs." Saruto smiles enjoying her caressing

"oya? a milf you say? since when?" she ask curiously

"since the day I saw her I guess." he said casually

"hah! you were a pervy since you 4! I know it! you will become a player! my education for you is naught!" she said in fake sadness

"you are jealous since you are not a milf yet." he said with a smirk

"boooo! naughty brat, " she said in fake angry but smiles afterwards "well, enough chitchat at the door, let's get in, I will do a quick bath and makes us dinner, wait until then~" she said with a wink

"aunty~" Saruto said with tone Aya know well

'he called me aunty! he is pissed! but why?!...oh S.H.I.T! the tape!' Aya had a cold sweat and said and shaky tone "y-yes, saru-chan?" she stutter

"can I joined you~? you see I'm quite sweaty." he said, a smile never left his face, but that smile give Aya the chills!

"emh...ano..I don't think..that appropriate.." she tried to give him an excuse but no avail

"hmm? why? I'm only 8~why I can't join you"

'8 my bubbly ass!' Aya thought internally but never voice it out "b-but..I'm your aunt.."

"aunty...I'm joining.."

"...yes." she gived up and decided to bite the bullet with nervousness but also excitement

****

in the bathroom, it was quite big , and can fit two adults with ease

"haaah, that's the life.." Saruto sighed relaxed "hmm? aunty? come one~" he said in the bathtub

Aya opened the door, the only thing on her is a long towel cover her curvy body, she had a huge blush on her face, normally that wouldn't happen, in fact, she enjoyed the bath with Saruto... until that incident... when she saw him in full adult form naked.., at that day she casually entered the bathroom, and she doesn't knock, her told her before but in her word 'my house, my rules.' she never thought such saying would backfire at her...

since that she never took bath with him, she couldn't face him naked, she always would imagine him in that form, Saruto respect that and never asked her about it, which she appreciate it , but today was different, she now Saruto is angry, and she understands why that's what she did what he wanted unconditionally

she hopes that he would be in child form, that was settled her pounding heart, but to her horror and she never thought but to her desire he was full naked in adults form

Aya is slowly moving to the bathtub with shaking legs, she approached the tub and start to remove her towels in shaking hands

Saruto notice this and sighs "aunty... aya-nee..if you really hate this too much, I won't force you.." he doesn't want for his aunt to hate him...no matter what she did ...

"saru-chan...I'm sorry...for the tape...I knew I should have taken your permission.." Aya looked down on the floor with red face, not from shyness and embarrassment but from shame

"haaah" Saruto sighed and smiles helplessly "it's fine..I forgive you..but next time ask me..I wouldn't mind" she smiles kindly to her

"saru-chan..." aya had teary eyes "..thank you.." she said with beautiful smile

"you are my aya-nee, my only left family..I won't be angry at you for long..welp.. time to go, you can enjoy the bath..I will prepare the dinner." he starts to stand you but a voice stopped him

"wait! saru-chan!"

"huh? what wrong aya-nee?"

"em.. what about my punishment?"

"it unnecessary, you know your mistake, I won't do something you hate" he smiles tenderly at her

"nt te it" Aya said in low voice

"hmm? what? I didn't catch that"

"...I don't hate it..." Aya said tearing to avoid his gaze

".. you don't? but you are shaking.."

"...I'm nervous..I'm might do something..I might regret..I don't it to effect our relationship..if this doesn't work.." she said nervously

"..what stoping you, aya-nee.."

"..your age...and you are my nephew..."

"I see..., well neither I'm against it!"

"but!! you are 8!"

"do I look and act like 8?"

"...no..."

"than that case closed."

"b-but how about our blood? it's morally wrong..."

"well..I don't let morals restrict me doing what I wanted with my loved ones." he said honestly

"saru-chan..."

"tell me..aya? do you want to take bath with me?"

"...I do..." she said with extreme blushing face

"I see.." then he stands up, and stand next to her , he slowly start to remove her towel, she flinched a bit, but soon doesn't resist, and soon he saw her body in full glory

"..Aya..you are gorgeous." he said honestly while caressing her head

"p-please.. don't stare much.." she said but never covered her body

"I can't help it.." he said as he brought he face closer, Aya know what he intentions but never showed sighing of backing of

she slowly watched as he gradually makes their lips closer until they touched..

they kissed tenderly without lust, few seconds later he removed his mouth and asks "do you like it?"

"hmm." Aya just nodded ".. more.." she said shyly

"of course but..let's entered the tub" he said as he guide her and he sets and let her set above him, they moved a bit to relax their position and make themselves comfortable

"are you relaxed, Aya?" said while washing her similar sliver hair

"hmm,yes... Saruto.." she called him with his full name this time

"I'm glad... come ,let me wash you." he said as he puts some soap on his hands and skillfully filled her body with it

"hnn~" she moaned a bit at his touch, he delighted to her such lewd voices from her and continued to moved towards some huge hills

"I need to clean this marshmallows too~" he said while playfully biting her small but lovely ear

"ahhn~♥️" under his touched he filled her chest with soap, bit never forget to pinch the little peral a bit

"ahhnn~~~♥️♥️ S-Saruto.. that's... quite s-sensitive~" she said but never complain

'she climaxed..?' he thought, and looked at her hazy eyes "s.. Saruto..k..kiss me.." Aya said weekly, the silver hair young main obligated and give her a kiss, but this time they used their tongues, they fought for good 40 seconds , but Aya tongue stopped moves and her eyes closed and her breathing calmed down "Aya?" he looked at her his beautiful sleepily face of his aunt
