...Niisan?
The bath is...
...You fell asleep here again?
With your clothes on and everything.
They're going to get wrinkled.
Niisan.
Won't you wake up?
...I'm going to undress you then.
Okay?
Well then...
...I'll start from the top...
*moan*
*sniff*
Ah...
Niisan...your scent...
*sniff*
Sweat and...
Something that smells different from me...
It's a... manly scent.
*sniff*
Niisan...
*sniff*
You're a bad boy for not getting up...
If you don't get up... I'll have to take your pants off, too...?
I'll undo your belt...
Take off your pants and your underwear... everything...
Ah...
Your...
It's... bigger than when I saw it in the bath before...
Oh... I smell it here, too.
*sniff*
It has a... strong scent...
*sniff*
Like... cheese... or natto... or fish.
Like it has slowly simmered over time.
*sniff*
It's been simmering all day inside your pants and underwear.
Sweat and... other things...
It's gotten musty and thick...
*sniff*
The smell of my big brother's... thing...
*sniff*
... The tip...
*sniff*
My nose... it smells and now it's stained...
The place where... the skin of your thing is covered...
This smells the most.
*sniff*
Inside here...
... It looks like you've been saving up a lot of smelly, dirty stuff...
Your thing...
I'll use my hand and... pull back the skin...?
Ah...
It's yellow all over.
It's filthy.
Even when you're busy at work, it shouldn't get like this...
Your thing... it's covered in smegma.
I guess that's just what happens.
Instead of my sloppy big brother,
I'll wash your thing for you.
It's a sensitive area so... I'll do it with my mouth.
*lick*
Ah...
My tongue... it tingles...
*lick*
It's bitter... and salty...
When I press my tongue up against it and rub...
It just peels off.
It's smelly... and dirty... and it's all in my mouth.
This spot... where your thing... is uneven.
It's so sticky... it's all over.
The smooth part, too... at the tip...
There's a milky coating... something white... right at the tip...
If I just lick it...
Let me make it softer with my spit...
I need to rub harder...
*lick*
Your thing... it's so smelly...
The smell... it's in my head... it's so strong... it's making me dizzy...
*kiss*
The part where it's uneven... this smells the most...
*kiss*
I'll close my lips hard and tight... and go back and forth...
And my tongue... it's sort of wrapping around the underside of your thing...
I move it... and rub...
At the base, too.
*slurp*
I'll take your thing... to the back of my throat...
It's big...
The smegma has gotten soft.
It's sticky like cheese on my tongue.
The smell of your thing is all in my mouth.
*moan*
Something slippery is coming from the tip.
I'll lick the pee hole... with my tongue...
*lick*
A lot came out...
Is this... precum?
It comes out... whenever your thing feels good...
An impatient liquid...
So... are you close...?
Hmm?
So you finally woke up, Niisan...?
Your thing was smelly and dirty,
so I was just cleaning it.
No matter how many times I say it, you never clean your body,
so as your little sister, I'll clean your body for you...
I'll pull back the skin on your thing...
And lick the built up smegma... and suck...
I looked up how to do it already...
In videos... and books...
Even in the naughty manga you used to look at often...
So... don't worry about it...
I will make you shiny and clean everyday from now on.
I want to do it for you since you are always working so hard.
I don't hate it in the least,
so please don't hold back.
Please let me clean your thing...
*moan*
Your thing has gotten thicker than before... and its bouncing around.
Does that mean... you're close?
Cum...
In my mouth... I'll lick the smegma from your thing and rub...
Are you going to cum?
Niisan...
... it's okay...?
It happens while cleaning.
For guys... this part should be cleaned every day...
The heavy part hanging down makes cum every day and it builds up, right?
If you don't let it out regularly... it leaks... in your sleep...
And you get horny and can't concentrate...
So just like housework...
I will help you.
Just like how you work hard at work...
Let it out inside my mouth and relieve yourself...
*kiss*
While sucking your thing...
I'll put my whole mouth around it...
From base to tip...
*suck*
It feels good... even the underside when I wrap my tongue around it... and rub...
I'll lick the smooth head over and over...
Please let it out...
All of it from your thing...
Your cum...
All the cum you've been storing up...
Please cum...
Inside my mouth...
Niisan...
*suck*
Something thick... is coming out of the tip of your thing...
It's warm... and bitter... there's so much...
Your cum is inside of me...
*swallow*
Please give me more...
I'll make your thing feel good...
Please let out the stuff stored up here...
Let it out inside my mouth.
Did you let it all out...?
*suck*
*swallow*
That was a lot of work...
*moan*
Look, I took a lot...
A lot of your smegma... and cum...
*swallow*
It's all caught up in my throat... it's hard to swallow...
*swallow*
*moan*
Ah...
There's something coming from the tip of your thing again...
*kiss*
*lick*
I got all the smegma from inside your skin...
Your thing is all clean now.
I'll clean it every day now, even tomorrow...
I'll help you let out your stored up cum, too.
Actually, does this mean...
My first kiss... was with your thing?
*kiss*
I saved my lips for someone special...
Now they're covered in smegma... and cum...
Now I can never kiss anyone...
I'll never know what a kiss between lips is like...
Because... you don't want to kiss... right?
A kiss with the dirty lips of your little sister...
...Niisan...?
Huh?
*moan*
*kiss*
A kiss...
*kiss*
Your lips... they're soft...
*moan*
Thank you...
I'm... fine...
You don't have to do anything else.
I can't believe you kissed my lips... smelly with smegma and cum...
*kiss*
My tongue...
*kiss*
Lick my lips... and inside my mouth...
*kiss*
Niisan...
*moan*
You stole... my first kiss...
Your lips... and your thing...
*kiss*
... you can take your bath now.
Please get in before it gets cold.
... of course.
We can both bathe together.
Niisan?
