The little brother’s name is Keita.
His older sisters’ names are Ako and Riko.
He grew up and enrolled in high school just like any normal guy.
However, the only thing not normal, is his twin older sisters’ giganto love for him.
Ako, Riko, and Keita are stepsiblings not related by blood.
Listen, Keita. If Ako tries anything funny, call me immediately!
Uh, sure.
Honestly, why are our parents going on an overnight pleasure trip with the neighborhood association?
Okay, that’s enough.
I’ll take care of Kei-chan for you.
You’ll be late!
Keita! Watch yourself!
So the hall monitors are supervising overnight summer camps?
I’ll answer the phone whenever you call!
It’s because
there were reports of lewd acts when the basketball team
had their summer training camp the other day.
So that’s why the hall monitors are supervising the other camps on a rotating basis?
Talk about collective punishment.
Tonight we’ll be all alone, together.
Right.
And now that Riko’s not around either...
“Either”?

Let’s spend the morning doing homework!
Afternoons get too hot for you to want to do anything.
So you might as well get it out of the way now.
Yeah, but it’s hot enough already! I can’t work like this!
Geez, you’re such a handful.
Fine, how about we buy some ice cream?
This has too many calories...
And this one has chocolate...
Ako-nee, are you done yet?
My ice cream will melt!
What are you, a kid?
But there were so many to choose from!
I’m sorry!
What are you doing?
We’re on a little date.
A da...?
It’s hot!
So what if it’s hot?
Kei-chan, you’re always like this!
Don’t blame me if we get all sweaty.
Sure!
You’re always...
... such a nice guy.
So you did want to get hot and heavy with your sister.
No I didn’t.
Now then, let’s get started.
Not happening.
Why not?
W-Well...
Oh yeah! I need to replenish the sodium I sweated out.
Your brain can’t function if it lacks sodium.
That’s “carbohydrates.”
Kei-chan...
You really thought it was sodium, didn’t you?
I-I only misspoke!
Kei-chan, look!
You can lick all the sodium you want right here.
But that’s your sweat, stupid!
Oh? You won’t lick it? A guy needs his sodium, you know.
Come on, come on!
Damn you!
You’re making fun of me!
Gotcha!
Kei-chan’s resistance to my temptations has been steadily waning lately.
I can use that to my advantage to get all cuddly with him, leading to...
Don’t!
You’ll leave a mark if you suck on me.
Just lick me.
God, you’re so fussy!
There’s nowhere left to lick anyway.
Actually, there's one more spot that's really sweaty.
My armpit?!
No!
Kei-chan, you’re kidding, right?
That place was dripping with sweat.
It must really stink by now.
This is embarrassing! This is too embarrassing!
You jerk! Kei-chan, you stupid jerk!
I know I started the whole thing, but this is just low!
What? But why?
I’m... I’m starting to “sweat” for an entirely different reason!
He’s licking my sweaty armpit...
and it’s... turning me on!
How could something so embarrassing feel so good?
I’m... I’m such a...
Kei-chan... ahh!
I can’t take it!
I’m losing my mind!
Suminoe
Delivery!
Suminoe-san?
C-Coming!
Suminoe-san?
Coming!
I took things way too far.
What the hell was I doing anyway?
I actually licked her sweaty armpit.
Am I a total sicko?
Yeah, but still...
God, why did Kei-chan have to do that?
Still...
I think he’s...
No...
He’ll definitely come to me!
Mom, Dad...
Tonight, your Ako will become a woman.
Sorry, Riko.
That voice...
Is Keita in danger?
What’s wrong?
Oh, watermelons?
Let me have some too!
Sure.
Chow time!
What?
We ran out of salt.
Wait, Kei-chan!
Here’s... your salt.
What’s wrong? Won’t you lick it?
Oh, God. Ako thinks I’m a total sicko!
Will you lick it if I rub some watermelon juice?
What am I, a fly?
Oh, okay...
Wait, you want to be licked, don’t you?
On your armpit.
And it looked like you were enjoying it too.
Just from having your salty armpit licked.
Or was it vinegary?
God, you jerk!
Don’t you have an ounce of delicacy?
I swear to God!
S-Sorry.
Crap, I made her mad again.
So...
Ako-nee?
We’re starting again fresh.
I just took a bath, so these are my real armpits.
Ako-nee!
If you’re going to poke fun, do it after tasting the real me.
S-Sure thing.
No! Don’t sniff me!
W-Well? Is it any different?
Yes! This is not how you taste!
It’s like licking a bar of soap!
You smelled and tasted way better in the afternoon!
You smelled me?
So you have some weird body odor fetish?!
I’m not weird!
Ako-nee, you washed away what’s good about you down the drain!
What you had in the afternoon titillated me to no end.
All I wanted to do was lick you.
I’ll make you remember!
Kei-chan!
Spread
K-Kei-chan!
He’s pinning me down by holding my...
His firm grip is making me go so limp, I can’t resist!
My armpit... my breast... everything feels nice!
More... more!
I’m starting to...
go blank...
Your nose is bleeding!
Shoot, where are the tissues?
I’m fine!
Kei-chan!
Come here.
This is really nice, Kei-chan.
Ako-nee...
Hold it right there, you naughty youngsters!
Riko?!
Why?
I knew it!
I had a weird premonition, came home, and look at what I find!
Why are you even here?!
Isn’t it obvious?!
To put a stop to your misconduct!
But we aren’t at school!
And you call yourself a student council member?
Good conduct doesn’t end at the school...
Oh no! Am I too late!
Y-You’re wrong!
You caught us before we got there!
Then show me proof.
What proof?
Show me your hymen!
Why would I do that?!
God, you’re always...
Right back at you!
...always trying to get a jump on me!
Same goes for...
Riko?!
Nobody said you can go home!
The teachers will get mad!
Let’s get back to our patrol!
Honestly!
Nooo!
Keita! Keita!
How the heck could we get interrupted, not once, but twice?
God! God! God! God! God!
Kei-chan, nooo!
So I guess nothing actually happened today, huh?
I’m hitting the hay.
What didn’t actually happen?
Eh, Keita?
R... Riko-nee...
Didn’t they take you back to school?
You can say I’m full of surprises.
It’s your fault we’re behind on our patrols.
You’d make a good hall monitor if it weren’t for your kid brother.
I’ve made sure nobody will interrupt us.
Now will you tell me what you and Ako did?
If you don’t...
There, I kissed you.
Now look here!
What’s the problem?
In western countries, people kiss each other to say “hi.”
Now how many times have I heard that?
Don’t try to fool me!
I don’t know what you think is going on,
but I’m telling you, nothing happened!
You swear?
C-Cross my heart.
Ako-nee is my big sister!
Maybe not by blood, but I’d never engage in any misconduct with her!
So there’s no problem if we’re not blood related?
Of course there is!
Then a kiss would never cause you to have any impure thoughts, will it?
No, it wouldn’t.
Oh? This is strange.
It seems we’ve found a guy who gets turned on by a kiss from his step sister.
Now who’s trying to fool whom?
And what’s this thing that’s been knocking on my door?
Wh... What are you doing?
You... know exactly what I’m doing.
If you’re still maintaining your innocence, I’ll just do what I want.
I’m making your area into my plaything.
You wanted to feel more of my panty parts, so you thrust your hips, didn’t you?
This feels great.
I could just go ahead and deflower you, but what do you want?
What to do next?
Anyways, you’ll only piss me off if you keep up that lame innocent act!
S-Sorry.
What? She was giving you “sodium”?
And you did that in broad daylight?
I never even knew you had a body odor fetish.
Come on, it’s not what you think!
You’re so silly, Keita.
You didn’t even have to lick her there.
A girl’s body has...
so many places...
you can lick.
Y-You moron! You know I can’t do that!
You can do that with Ako, but not with me?
Keita!
Hold on!
Why Ako and not me?
Come and see how I taste!
You need to treat us equally.
Your scent... your smell...
That’s my...
K...
K-Keita...
N-Not the ears!
Okay...
Is that...?
Wh-What?
Your bellybutton...
collected a lot of sweat!
No... Keita...
No, Keita! That’s gross!
Why there?
God...
Everything is entering through my nostrils and filling up my entire body.
H-Her taste...
I can’t take it.
Keita...
Taste more of me.
Taste how much you really turned me on.
Keita...
Morning already?
I need to make breakfast for Keita.
What?
Hey! What’s going on here?!
Hey! A little help?!
Kei-chan!
So, after I finally escaped from my room, why did I find you here?!
Yeah, well...
It’s a long story.
So nothing really happened between you two?
Nothing happened, honest!
Anyway, I have to get going!
My track team has morning practices starting today.
I also have to get back before noon.
Very well.
I’ll see you later,
Kei-chan!
You need to start getting comfortable kissing people in public.
As if I would!
God, what’s with Ako’s attitude back there?
What’s the problem?
In western countries, people kiss each other to say “hi,” you know.
I thought you didn’t want to hear that.
In any case...
You know what you promised me yesterday, right?
Yeah, I know.
Are we good now?
Everything I do with Ako-nee I’ll do with you.
You’re so adorable when you’re compliant.
This is for Keita when practice is over...
Tastes great!
Oh yeah, do you want to help with hall monitor duties after practice?
Why would I? You’re killing me!
And Riko-nee, it’s too hot for that!
If I could, I’d never leave your side.

Here’s Suminoe Ako!
And Suminoe Riko!
Hey, Riko, did you know we’re now on our tenth KissxSis OAD!
We did that many?
The only reason why we got to this point is because of our loyal fans.
That’s right!
We’d like to thank all the fans who gave us their support!
This sort of feels like the last episode, though...
What are you saying?
Our lovey-dovey days with Kei-chan aren’t going to end anytime soon!
