Original subtitles

- Big sis, they're calling. - Okay.

Do you have a stomachache? Are you okay?

- What is it? - Your seatbelt.

Oh, i forgot.

Yuuta, it's been a while since we all ate out. I'm so excited.

If she were the old her, thst's how she would have acted.

She used to be so cool. Now, she's always afraid, and needs to go to the hospital every now and then.

You're saying your daughter used to be very cheerful, and was doing great at school.

Yes.

They way he used the past tense definitely made my mother twitch.

She was so proud of her, but not much of her past delf remains now.

Do you always visit the therapist together as a family?

- No, we're here because we had plans to eat out together after this. - I see.

I would like to talk with your son too. Can you please come over here?

Okay.

Is there somrthing you want to say?

Huh? No.

You don't know anything about her condition?

Not really... i did try search information.

- Did you fine anything? - No, nothing.

How long do you think it will take her to recover?

I think it's impossible.

There's nothing wrong happening in her life, and she is still unable to deal with it yourself. It's pitiful.

I think her condition would improve if we stopped taking her to therapists like you.

Understood. That's all.

Ah, Yuuta...

Your parents have given me a large sum of money to handle this case...

so i still intend to do my job for what it's worth.

Hey now!

Yuuta doesn't care if i smoke.

U-umm, the bath towel...

- Why didn't you call mother then? - Oh... yeah.

- Water is dripping from your hair. - I'm sorry.

- It's fine, be careful not to slip. - Y-yeah.

- I'll wipe it. - Thank you.

She used to be a cool big sister.

She isn't as cool as before, but i don't think she's changed much.

She's just bad at taking care of herself now.

Hey! What's that sound?

What are you doing?

I fell... i had a nightmare.

- What kind of dream? - I died in it.

I was spacing out when a train ran over me.

Is she closing herself off in her dreams? If she's dying there, does she not want to live anymore?

She was close to me ever since i was born. I always looked up to her.

First of all, i would like to thank my friends and family who have always supported me.

She was the pride of our family.

I think that doctor understood that i was trying to tell him not to mess with my sister.

because she hasn't gone crazy.

I believe his response then was a single to let me handle things instead.

I plan on giving my all to help her however i can.

Are you mad about something? Did i do something bad?

No.

Thanks for wiping the water on the stairs.

Isn't there anything i can do to help her?

Good night.

Something to make her want to live again.

Yuuta?

Can i really do it?

I want to do something for your sake, but i can't seem to do anything right.

- That's unexpected. - Huh? Uhh... what?

- Will you do my homework? - You should do that yourself.

All right, then. Take off your clothes.

My sister... My one and only big sister...

Stand up.

Okay.

I don't mind, but why?

What are you doing? What should i do?

They're pretty big.

That's because i'm your big sister.

All right, i'm feeling energized again. I will get serious starting tomorrow.

We're done already? You didn't do anything.

Fine, show me your naked body every day from now on. Is that okay?

Every day? O-okay.

You're so nervous. Your nipples are hard.

Yes.

- I'm gonna touch them. - Yes, go ahead.

- Are you okay? Does it hurt? - No, i think i like it.

I'm sorry. Are you okay?

Y-yes.

- Good night, then. - Wait, Yuuta.

Thank you. I'm glad i'm alive.

Come again to look at my naked body tomorrow.

Yuuta.

When are you looking at my naked body again?

Let's see... maybe tonight, the same time as yesterday.

I understand.

What's with this sexy choice?

What were you doing? Studying?

- Yeah, didn't i say i'd get serious from today onwards? - Oh, really?

- You're studying? - Yeah. - That's amazing. I might be able to help you a little.

Big sis, you've worked so hard until now.

Hm?

I've straightened up now, you can relax.

You just need to be here with me forever.

If you're fine with that, i want to stay with you too.

I'm coming in.

Yuuta. Yuuta.

- Wait, okay? I'm in the middle of stripping. - Stay like that.

Let me see your ass.

Yuuta.

Yuuta.

Yuuta, Yuuta, Yuuta.

Yes.

Yuuta, are you awake?

Good morning. Good morning.

Big sis, you look cute and sexy again today.

- Spread your legs. - My legs?

- Like this? - Yeah.

That's right.

- Move your hips. - My hips?

Shake your boobs.

Lift your hands.

- Move your hips faster. - Faster?

Are you okay? Did it hurt yesterday?

N-no, it didn't hurt at all.

I'm glad.

I'm cumming!

I'm home!

- Yuuta, welcome back. - Hey there. - Welcome back.

What have you been doing all afternoon?

I was spacing out in my room, and looking around.

But i was thinking about you in my room today, and time passed so fast.

Were you thinking of naughty stuff?

Is it okay to think about doing naughty stuff with you? Is it fine to be naughty?

- Think about whatever you want. - Got it! Please come to my room today, okay?

Big sis, i'm here.

Yuuta! Yuuta!

_ this is way too sexy. - You don't like it? I thought tha-

Listen...

Ever if you were cool before, and now you're not, i love you the most right now.

- O-okay. - So don't worry about anything, okay?

Show me how naughty you can be.

I will show you my boobs.

Yuuta.

Yuuta.

Yuuta.

Yuuta.

We're out of breath.

I'll show you down here too.

Here.

- More. Show me more. - Here.

Yes.

Yuuta.

Yuuta.

Yuuta.

Yuuta.

Oh, Yuuta.

I can't stay standing.

I'm sorry.

I was lost in a trance.

I want to play with your dick too.

Okay.

Show me.

I'm taking it out.

Amazing, Yuuta's dick...

Yuuta's dick's amazing.

Big sis.

Big sis.

Big sis.

Yuuta. Yuuta.

I'm cumming.

It feels so good, Yuuta.

Big sis.

- Yuuta, Yuuta. - Big sis.

Yuuta.

Big sis, big sis.

Yuuta.

About this part...

Ah, just use this equation to combine this and this.

Then i take the result from here? Wow, thank you.

You're amazing.

You're more amazing. You're already doing tough problems like this.

- You already worked out the formula too. - Yeah, but my results are often wrong.

- I see. - Will you teach me if i get stuck again?

Of course!

Wh-whoa! Yuuta?

Hm?

Yuuta, i knew you were working hard, but i didn't expect this.

But you can't relax just because you got good grades, okay? You need to talk with your dad too.

What's with what? You guys are too afraid of big sis.

You don't have to worry about me. I will raise to your expectations. I won't be a burden.

Your sister always said you're amazing. That you could do anything if you try.

That's why she could work so hard.

Wait, the reason she worked so hard and pushed herself so much... No, i can now imaging that more than ever.

Yuuta, what's wrong?

What are you doing?

I was thinking of teaching you more.

Are you sure? Aren't you pushing yourself?

It looked tough at first but now i understand most of it.

Why are you still looking out for me so much? You're in this state now, you should take a break.

I'm glad this happened to me.

I always wanted you to hug me and spend more time with you.

Before i realized it, i was more in love with than ever.

Big sis, come here. Let's have sex.

- Big sis. - Yuuta.

Yuuta.

It's in.

Hey.

Even if you didn't turn out like this...

you still would have been mine, and i still would have been yours.

Yuuta.

Yes.

Yuuta.

I'm cumming.

I'm cumming.

I'm cumming. I'm cumming!

Oh yes.

- Oh, Yuuta. - Big sis.

So good.

Big sis!

Big sis...

Yuuta.

Yuuta.

Oh no.

Yuuta.

I can't stop.

- It feels so good. - Me too.

Wow.

Yes.

Yuuta, i love it.

Yuuta! Yuuta!

Yes.

More.

Yes.

Yuuta.

Sis.

It feels so good Yuuta.

Yuuta.

Yuuta, Yuuta, Yuuta. I love you.

Oh yes.

- Yuuta. - Big sis.

- Big sis, does it feel good? - Yes.

- Your dick makes me feel so good. - Your pussy feels amazing too.

Big sis.

Yuuta.

Yuuta.

I can't hold it in.

I'm gonna cum big sis.

I'm cumming!

- Let's get marrried. - Sure. - That was fast.

I was also thinking of marrying you.

I don't want to make you wait, but this will take some time.

I talked to mom and dad...

- they said i can marry you. - What?

- We're not related by blood anyway. - Is that true?

- Didn't you notice we have no pictures of us when we were little? - Not at all, did you?

Yeah... mom and dad already told me there is no problem. They want us to be happy.

What the... from start to the end, everyone around me has been taking care of me, and i just took everything for granted.

- Big sis... - Hm? - Thank you.

I think i will be relying on you a lot from now on. Let's tell everyone.
