Original subtitles

I, Oomiya Reina, have a younger brother.

Attack!

Ouch!

What the hell are you doing, Shouta?

I just... I wanted to see Sis' panties.

And he's long been a siscon and obsessed with his sisters.

Shouta, he...

He has no blood connection to me or to my younger sister Aina.

So let's kiss to make peace...

Oh, my God, there's no choice, then.

I always spoil him because he's my younger brother,

And so, he always sets the pace.

At that time, I consented to every whim of my younger brother.

Yeah, since we were little.

Sister Breeder.

Gosh, Shouta fell asleep again.

I'll text it to Dad.

A-Aina, everything but that...

Mom and Dad said they were going abroad for a year,

And they trust us to take care of the house...

Remember to attend the student council meeting, Shouta.

Got it.

Since he's older now, I'm sure he won't do that again...

Wait, you two.

That thought made me see that I was naive.

Yeah, today's panties are pretty, too.

His Sister Complex is still there.

No.

Gosh. Doing this every day.

I-I'm sorry, your ass is so cute I couldn't help it...

I'll reflect on that, okay?

Ever since our parents left home,

This harassment disguised as affectionate interaction a has been scaled even more.

S-Shouta...!

This...

...it's not good!

Well... I'm leaving first.

This kind of thing... it's not right.

I...

Today I have to convince him without fail.

Well, that's it.

The third ordinary meeting of the Student Council is concluded.

Good job.

President Reina, I'll take care of it.

No need. I remember where the documents are.

He remembers them, too. Leave it to us.

I'm jealous of Reina-senpai.

Should I take a chance and confess to her?

Someone with a pure heart like her wouldn't date someone like you.

You heard.

My pure-heart sis.

Who would have thought, that you...

...would wear such lewd lingerie to a meeting.

I'm sure everyone didn't even think about it.

Didn't you tell me to wear it?

Shhh!

If you talk so loud, someone could hear us.

What am I doing...?

What are you doing?

Sis...

Shut up, keep your voice down.

I'm going to pay you a night visit.

H-Huh?

Mom and Dad won't be here by the year. This is my chance.

I love you and Aina more than other women in the world.

In a romantic way, of course.

Inces between brothers is totally forbidden,

But that look of Shouta...

It's very serious.

Wait... if you have to do it, no matter what...

I, as your older sister...

I had the intention of...

...persuading Shouta to protect Aina...

These last ten days, my younger brother...

He's always been manipulating me...

I may already know all your weak points, Sis.

Yeah, touching your breasts is the best.

I can't. It's just, I haven't...

Oh my, Sis.

You've exposed your own weakness.

You want me to bother your asshole instead of your nipples?

Don't spread my anus!

Good girl, cleaning your anus well.

That's...

It's because... you've been playing it every day...

Yeah, you like the feeling of getting your ass teased, don't you?

But if you don't lower your voice, someone will really hear us.

Come on, come on, do your best!

Y-Yes...

I have to hold on.

When this act is over,

I'll convince my younger brother, no matter what.

Hey, is anybody there?

Huh? It's locked.

This is bad, if someone see me like this...

I have a brilliant idea.

T-That... definitely won't work.

All right, I'll open the door.

T-Teacher...

It's me who's here.

That voice... are you the president of the Student Council?

Yes, I'm Oomiya Reina.

I see. I've heard some strange noises in there.

W-While ordering the files...

t-the books... fell off the shelf.

What's going on? Are you okay?

N-No problem...!

They fell again? Let me help you, open the door.

The books... they fell and...

My clothes are all messed up.

Ah, that's why you locked up.

There are rumors of students having sex at school lately.

I would never...

I know.

Since you're famous for your rigorous discipline, president.

I'm sorry to interrupt your work. Keep it up.

My mind is completely blank.

It was thrilling and exciting, wasn't it?

And those rumored students, are definitely us, isn't it, Sis?

You came and you didn't listen to me.

How shameful, my younger brother raped my anus.

And then he cum in front of others.

But...

It felt really good.

I think it's time.

You've been wanting to feel good for a long time, haven't you?

W-Wait, I told you before, didn't I?

Brothers can't do this kind of thing.

In that case,

I'll give you a kiss and let me put it in.

No, don't do that.

Stop, please!

If you kiss me again... after I reach an orgasm...

I knew it.

When I kissed Aina this morning,

You were looking at us with jealous eyes, weren't you?

Yeah, I want to kiss him, too.

Huh? Why? Why did you stop?

I can't hold back anymore. I'm gonna put it in.

More...

Keep kissing me... don't stop.

Your inside is amazing, Sis.

Shouta... is really...

My hips can't stop!

We, as brothers... really... are having sex.

Well, since we're brothers,

...we can't get married, right?

But I don't want another man to take you.

I'll train you to depend on me forever!

Train me?

As brothers, we shouldn't have that kind of relationship.

However...

Sis, become my sex pet.

...I feel completely delighted.

I can't think straight now!

Alright, I will be. Let me be...

The sex pet of my dear younger brother.

Yeah, I'll feed you forever as my pet, Sis.

It makes me happy...

Being my younger brother's sex pet...

What a wonderful thing.

It doesn't matter what the others say.

Even though my younger sister repudiates me...

I don't want to be separated from my younger brother.

Sis!

It feels amazing! I like it so deep!

Your penis is at the entrance of my womb...

I want to release all my semen into your womb.

Yeah. Give me everything.

Let my body and mind fall into the abyss!

With no turning back!

I won't be able to come back anymore.

Sis, I'm still...

I know.

You're not satisfied yet, huh? Me neither.

Fill me up with semen. Let me be a bad sister.

I'll give it to you!

So much that you'll be soaked with the smell of your younger brother!

I'll let go and give you all the semen I have!

Give it to me. All my younger brother's semen.

Ma... mark everything, my ass and pussy with your essence!

Shouta came inside me...

I'm becoming your pet...

Right, I have a present for you.

Here, a special choker.

Oh, you don't like it?

I never thought receiving a gift like this would make me so happy.

Does it suit me, Master?

Yeah, I knew it.

I also have a brother complex.

I'm home.

My friend is cold, so I couldn't stay at her house anymore.

Huh? The voices of Reina and Shouta?

I'm about to cum again.

Although I wanted to come inside your pussy and ass.

Last time you came in my ass too and it hurt for a long time.

Aina won't be home today.

I'm sure we're going to continue until dawn, right?

Until my butt heal...

Why Shouta...

...be content with a blowjob.

...and my dear sister...

...are naked and having sex?

W-What is this?
