Track 1: Can I Sock My Annoying but Cute Big Brother?
Hello, it’s your brother. I’m currently riding on a tuna fishing boat～
Hello, hello, it’s your big brother.
I lied. I’m right behind you right now～
Heroine: shakes in place with anger
Huh? Why aren’t you turning around? It’s me. Me, me. Are you not able to tell by the voice? It’s your wonderful big brother.
Oh, I got it! It’s been so long since we last saw each other that you’re so overwhelmed with joy that you’re shaking and aren’t able to listen. Yes, yes, I understand, I understand.
It’s fine. You can take your time, so turn around.
Jump into my arms, MY SWEET SISTER-
Is…isn’t that a bit much? To just punch me the moment you turned around……
No, but it was a really nice punch.
Even your single punch makes you shine with a light that separates you from others. As expected of my little sister.
Who’s the one that’s actually cruel?
Well, umm…I do feel bad for not contacting you for years. I’m a really busy person, you see.
Hold right there! Even if you’re my adorable little sister, I’d like you to refrain from digging any further. It’s a matter of national security.
Let me do this again.
Come, jump into your big brother’s arms!
Heroine: mouth wide, speechless
Huh? Uh, is something wrong?
Oh, are you embarrassed perhaps～?
Goodness, you’re such a handful. If you aren’t gonna come to me then I’m gonna come to you!
As always, you’re so dainty.
Hey, hey, don’t flail around so much.
Ow, ow, ow, it hurts! It really hurts! Don’t grind your heels on my foot.
Did some accident happen?
I guess this area has become unsafe recently. To think this street we used to walk hand-in-hand through when we were little would be dangerous.
But don’t worry.
As long as Big Brother is with you, no one would be able to cause you harm-
W-What is this!?
Wait, wait, wait. Eh? Why are you pulling us apart?!
I’m not a pervert! Right now we were having an emotional reunion-
Please listen to me!
Hey, officer? Officerー?
T/N: Heroine is unvoiced, the lines came as a part of the script
Track 2: My Annoying but Cute Big Brother is Acting a Little Strange?
Ahh…I’m so glad that the officers managed to somewhat understand. I was nearly thrown into a dangerous police cell.
Heroine: huge sigh
My dear sister, what is the matter? You let out such a huge sigh.
Oh, I see, I get it. You must feel regretful that someone poured cold water on our beautiful, emotional sibling reunion just like me.
Heroine: What I want to ask is why are you back now out of all times…?
Eh? Why I’m back now out of all times?
Hahah… Obviously, it’s to see the face of my cute little sister.
Have Mom and Dad been doing well as well? I was worried about them overexerting themselves since the two of them have a lot of things going on but they’re surprisingly resilient, I feel.
Who do you think is the cause of those headaches…?
Indeed, it was me!
My, my, touche. Ahaha!
Heroine: The two of them are on a trip and aren’t home.
Eh? …What did you say? The two of them are on a trip and aren’t home?
Even though their darling son has crossed great distances and returned home, why did they have to go traveling? Isn’t this where they cook up one of your favorite dishes and greet you with a smile?
But I mean, since I came back without notice, it’s not like they had known, hehe…
Oh, we’ve reached our house without realizing it as we were talking.
……This house has barely changed from before. It’s the exact same as it was in my memories.
Heroine: unlocks door
Heroine: Don’t just stand there, get in.
Oh, sorry, I stood there in a daze… Also, isn’t that rude?! I was just immersed in my deep emotions.
Nostalgia as they would call it, I think?
As a poet at heart, my overflowing emotions are right now being turned into verses inside my head……
Heroine: If you aren’t going to come in, I’ma shut the door.
Wait, wait!! I’m coming in! I’m going to come inside the house, so don’t shut the door!
Sorry, for the, uh, intrusion.
Heroine: It’s weird to say that you’re intruding on your own house.
Eh? It’s…weird to say that I’m intruding on my own house?
It’s fine. At this house, I’m more like a “guest” if anything.
Heroine: Welcome home, Big Brother.
Just now… “Welcome home, Big Brother”…
I’m home. Yes, I’m home.
“I’m home” is such a wonderful phrase. Just by you saying “welcome home,” I…
But still, even though you were super resistant when I tried to hug earlier, now you’re quiet almost like a lent cat. I can feel your warmth directly inside my arms. The feeling’s almost…nostalgic.
In the past, I often held you like this, right?
Whenever our parents would get angry at you, whenever you would fight with friends, or whenever you would just feel helplessly anxious……
I would listen to you talk like this while stroking your hair.
Perhaps, aren’t you feeling that way right now? Because if you want, you can talk to Big Brother about it.
Come on. Come on, come on.
Guh! Augh, ow… What did you straight-up headbutt my chin for? Big Brother was so close to nearly biting off his tongue.
Look at this, my jaw’s probably broken.
Heroine: Don’t get carried away.
Huh? Don’t get carried away?
You’re so harsh, my dear little sister. But that standoffish part of you is cute too.
Wait, don’t just ignore me and leave.
Hold on a minute, wait.
Oh? This living room is nostalgic too.
I see that the hole in the wall has been plugged up.
I mean, it was a hole that was made when I dodged Dad’s punch the last time I came home, but since it’s in such a conspicuous place, you probably thought that I, uh, did something really bad…
But even so, being able to punch a hole into the wall at that age? That’s not an everyday occurrence. It’s great that he’s healthy. Ahaha.
Heroine: For now, why don’t you have a drink?
You’re going to prepare me a drink?
To have such a nice sister, Big Brother is overjoyed.
Well then, the usual, please.
Hmm? Like I said, the usual. The special coffee, made with my usual special blend……
Uh, yes, sorry. Instant coffee is fine. Or you could just give me tap water, I won’t mind.
Heroine: I’ll brew some instant coffee.
Eh? You’ll brew me instant coffee?
Oh, I’m so happy!
Hehe. It sure brings back memories when I see you in the kitchen with an apron. One time you went “Big Brother, I’m going to bake you some cookies” and tried to make them yourself, right?
You put on an adult apron and tried your best to make them while being covered from head to toe in flour.
However, you messed up with the baking part and ended up with cinder-like cookies.
Heroine: I don’t remember things from that long ago.
Huh? You don’t remember things from that long ago?
I see. You are now a university student, after all. But that being said, Big Brother remembers it clearly. Your tears welling up because you failed, the horribly bitter taste of the cookies…
……I have so many precious memories made inside this house.
But, I wonder why? The more I’m reminded of those memories, the more a feeling more bittersweet than those cookies I ate spreads.
Heroine: Here, go ahead.
Ohoho, that’s some delicious-looking coffee. Let me drink it before it cools… Ah!? HHHHHOTTTTTTTTTTTTTT!!! Ahh, gah, gah, m-m-my crotch, the coffee spilled onto my crotch…!
Wait, wait, I’m fine! Y-Y-You don’t have to wipe!
Heroine: You’re gonna get burnt, so we have to cool it somehow!
I-I, I know it’ll be bad if I burned, but umm… Ahh… If you rub it so hard like that… Ngh! Stop!
Whoa, whoaーー! B-Big Brother is going to go to his room for a bit to change!
You haven’t thrown away the stuff in my room yet, right? I mean, it’s the house I’ve been away from so long, after all. I thought I’d, uh, spend some time in my own room.
What I mean is, my dear little sister, I may be back in my room, but don’t mind me, just relax!
I’ll be off then.
Oh, uh, the coffee was delicious! Please brew it for me again.
Track 3: Is It Okay for Me to Bully My Annoying But Cute Big Brother?
Oh crap. Oh crap, oh crap, oh crap, oh crap, oh crap…! Her, rubbing my crotch with such precision!?
No, calm down. She was genuinely trying to wipe away the spilled coffee. There’s no way my pure, innocent, untouched sister would know how to handle a dick.
……At least she shouldn’t.
I can’t go back while I still have a boner.
I always picture it when I masturbate, but… Even though I had my pants on, she was…touching me and rubbing me. To think it could happen for real.
It’s no use, thinking about it made me even harder.
I guess I have to stroke it off at least once.
Ahh… Damn… It feels so good…
Yes, there. The tip, head part of my dick that sticks out… Wrap your hands around it and stroke it hard up and down.
You’re doing good. It…feels so good that I’m about to cumーー
UWAAHHHHHHHHHHHHHHHHHHHHHHHH!!! Don’t just suddenly barge through the door, it’s improper AWSEDRFTGYFJKOLP.
W-Wait! Don’t come near here.
Or no, don’t look! I-I’ll put my dick away…
Ahh! IT HURTS, HURTS!!! You’ll tear it off, you’ll tear it off!!
Heroine: Who were you jacking off to?
Eh? Who was I jacking off to…? Umm, uh, I wasn’t thinking about anyone in particular. If you really want to know…it was nothingness?
AHH, OW, OW, OW!!! I’ll talk, I’ll talk! I’ll talk, so please take that hand away, please.
Heroine: remove hand
Heroine: I couldn’t hear that, though?
Like I said, it’s you. I was masturbating while thinking of you!
Heroine: What!? M-Me?
That’s right! I’m a man who uses his own little sister as fap material!!! Also, why are you able to just grab a person’s dick without hesitation!? Big Brother doesn’t remember raising you to become that way!
Don’t tell me you’re…no longer a virgin? Did you like, get together with a flashy, party-going senior from your university and offer your virginity to them?!!
How could this be… For my lovely little sister to turn into a slutty bitch while I wasn’t looking…
Even when I tried to get away from you, even when I try to forget about you, I couldn’t erase you from my mind. Every time I would masturbate, I would keep seeing your face. Even with the girlfriend I had finally gotten, whenever it came time to have sex, because your face would pop up, I would feel a sense of guilt and be unable to get it up…
So I got dumped entirely.
But, but, you said it, didn’t you? “When I get older, I want to be Big Brother’s wife”…!!!
Heroine: stares at Big Brother’s face
Heroine: Big Brother, are you…in love with me?
Huh? “Big Brother, are you…in love with me”?
That’s…right. I’ve always thought of you as a cute little sister and was planning to pour all my love into you. However, at some point, I lost control of my love for you and thought about wanting to be connected not just emotionally, but also physically.
And that’s why I tried to get away.
I was fed up with living in this house anyway, with the parents that saw me not as me, but as a thing to project their own desires onto. I thought if I left where I was and headed off to a new place, both my feelings and I would be reborn anew.
……But it was no use.
No matter much the environment changed… If anything, the longer I was away from you, the more you occupied my mind. But if you think about it, it’s only to be expected, right?
The moment you, my little sister was born, I was your big brother, and that fact has been the basis of who “I” was to this day.
Heroine: Leave to where?
Where? Anywhere but here. Now that I’ve told you my feelings, I can’t ever come back to this place again.
I mustn’t come back.
Oh, what the hell am I even saying with my dick out in the open?
Heroine: pushes Big Brother down
W-What are you doing!? Even if it’s you, if you suddenly push me down, B-Big Brother will get angry!
Heroine: strokes Big Brother’s dick
Whoa, what are you touching!?
Heroine: You wanted me to do this, didn’t you?
“You wanted me to do this, didn’t you”?
Y-Y-You bitch! You ignored a man’s desperate confession and went straight to playing with his dick. To think you were a little sister like that, Big Brother is saddened-
Stop… Stop focusing on the head…
Heroine: There’s a clear fluid leaking out.
Huh? There’s a clear fluid leaking out?
Stop closely observing someone’s dick! It’s…pre-cum, it’s something that leaks out when a man’s aroused.
Heroine: Wow, there is more and more leaking out ～ ♪
There is more and more leaking out?
Don’t say it with such glee!
Ahh, I can’t take this anymore. Why is my biological sister happily stroking away at my dick?
No, d-don’t dig your nails into the tip. The stimulation is too much…
Heroine: Does it feel good?
Does it feel good, you ask?
Of course it does. I react to just physical rubbing, so if I’m getting stroked off by the person I’ve always liked, controlling myself…is impossible.
No, no! If you go that fast, I…I’ll cum!!!
Heroine: Just cum.
How could I cum in front of my own little sister!?
Hey, I’m begging you, please, please stop stroking me… Big Brother was wrong, Big Brother was wrong, so…
Heroine: You like me, so it’s fine, no?
If I like you then it’s fine…? That’s not how things work!
I’m cumming… I’m going to cum… I’m going to ejaculate from my little sister stroking me…!
No, I’m cumming, I’m cumming!
Ahh! Your face, your clothes, my cum is… Why? Why is this happening? Out of all things I bukkake-ed all over my little sister.
Heroine: licks cum
Oh my god!!! Y-You just took a lick of my cum just now, didn’t you?
Spit it out, spit out. It’s dirty.
Heroine: ……I don’t dislike Big Brother’s taste.
Eh? “I don’t dislike Big Brother’s taste”?
Wait, what are you saying?!!
I can’t anymore, what do you even want from me? Big Brother had been desperately trying to sort out his feelings so that he could give up on you, but then you keep interfering.
Heroine: ……Then I’ll keep interfering.
Then you’ll keep interfering? What do you mean by that?
Heroine: tries for a kiss but knocks into teeth
THAT HURTS!!! You suddenly brought your mouth close to me so I thought you were going in for a kiss but instead you smacked your teeth into mine!?
I mean, it’s true that you’re in the same amount of pain, but… Seriously, what are you trying to do?!
Please, please don’t bully your Big Brother anymore than this.
Heroine: …You’re so goddamn dense.
Dense? Dense, what? Big Brother is?
Heroine: I like you too, Big Brother.
Heh? W-W-What, why did you just…say?
“I like you too, Big Brother” is that what you said?
Heroine: W-What’s wrong!?
I’m sorry, I didn’t think this could happen. To think that you liked me too.
So we were mutually in love…!!! And by the way, what is it that you like about Big Brother?
Hey, tell me, tell me, tell me-
Heroine: I hate the way you immediately get carried away!
You hate the way I immediately get carried away? But didn’t you just say that you like me?
Alright…I’ll try not to get carried away.
So, can we try kissing again? This time gently so that our teeth don’t smack into each other.
I’ll go for it then.
Damn… Your lips are so soft and plump, and I wish I could savor them forever.
Y-Your tongue, your tongue went in!
Wait, you… Sticking your tongue in, where did you learn that from!? If it turns out you’ve already done everything with another man while you claim you love Big Brother, Big Brother will go crazy!
Eh? W-Wait, wait! P-Please don’t cry, Big Brother was wrong. I, I’m sorry for doubting you.
Come on, cheer up. Alright?
Heroine: I don’t want to.
Wait, wait a sec. Sister?
You say you don’t want to, but why are you stripping Big Brother’s upper half? At this rate, Big Brother will be completely butt-naked.
No, wait, I’ll still have my shoes on.
Wait, doesn’t that make Big Brother look even more stupid!?
Heroine: This is your punishment for doubting me.
Eh? “This is your punishment for doubting me”?
Hahaha… Stripping your big brother naked, what are you trying to do?
When you gave me that handjob it was without warning. I won’t let you make cum me that-
Heroine: gives handjob and licks nipples
Don’t lick my nipples…! Please don’t thoroughly lick my nipples so lewdly with the tip of your tongue while you stroke my dick!
Damn it, why is it that you know that…I’m to my nipples?
Heroine: Oh? You’re weak to your nipples?
Don’t scratch my nipples! Licking one side and scratching the other with your nails… Ahh, I’ll lose my mind!
No, no, I’ll cum again!!! I’ll be made to cum by my little sister again!!!
Heroine: Go ahead, cum lots for me.
Big Brother can’t be doing that…! I can’t. I’m cumming, I’m cumming again!
Heroine: You came so much again ♡
It’s not fair that you’re having all the fun, you keep toying with me.
Also, first of all, why am I completely naked while you’re fully-clothed? Don’t you think that’s unfair?
Listen to your Big Brother a little, please.
Heroine: Then, what do you want to do?
Eh? “Then, what do you want to do”?
Your… I want to see your boobs.
That’s right, boobs! I want to see your boobsーー!
Heroine: …Alright, sure.
Eh? Y-You’re really going to undress!?
They’re beautiful… Can I touch them?
Heroine: Go ahead.
Wow, they’re so soft. I just sink right into your skin and can’t pull away. Also, they’re just the perfect size to fit into my hands…
Say, is it alright if I sucked on your boobs?
Heroine: gestures to her lap
Huh? On top of your lap?
Do I just lie down? Like on my side?
Okay, I understand.
Ohhh, what a wonderful sight to behold.
Don’t mind if I do then.
Mouthwatering, so mouthwatering…
Your boobs taste so good that I can’t stop sucking them.
Huh? Y-You’re grabbing my dick again!?
Stop, don’t stroke it…!
But, but you haven’t even gotten a chance to feel good, so if I… I want to make you feel good! I want to become one with you and make you feel good!!!
Heroine: stops hand
Sorry for asking things of you.
Since you’ve stopped your hand, umm… Does that mean it’s alright for me to put it in, inside you?
Big Brother will do his best to make you feel good. And uh, I’ll make sure that at the end I cum outside not inside……
Why are you smiling all of a sudden?
Jeez, you’re so cute. I feel like it’s been so long since I’ve last seen that smile of yours.
It’s too cute, so going forth, only show that face in front of me, alright?
Doing it on the floor would be hard on you, wouldn’t it?
Come on, let’s move over to this bed.
Ahh, beautiful… You’re beautiful.
With each piece of clothing I remove, more of your soft skin becomes visible.
And look, now you’re in the same state as me.
It’s like a dream.
For you to be pinned down by me like this… Just seeing you naked is…
Look, I’m rock hard again.
Can I? I’m going to put it in.
It’s a…little tight.
But, the moment I go past the entrance, it suddenly-
So hot. So this is what your insides feel like…
Your hot folds are sucking my dick in and coiling around it. It feels so good. I can’t. I can’t stop the movement of my hips.
The moment I make a single movement… It just feels way too good and I can’t stop!
I can’t. I’m going to cum.
Your insides feel so good that I’m going to cum!
I, I have to pull out.
Heroine: leg hold
Eh? EHH? W-W-Why, why are you-
W-Wait, wait! If you force your legs together like that, I won’t be able to pull out!!!
I’ll cum. At this rate, I-I’ll end up unleashing my cum inside my little sister’s pussy…!!!
Heroine: I’ve been on the pill for irregular periods, so it’s fine.
Huh? Irregular periods…? You’re on the pill, so it’s fine to cum inside? What? I don’t quite understand, but it means that it’s okay for me to cum, right?
Then I’m going to cum.
I’m going to pump all my semen inside of you!
No more, I can’t. I don’t have any more cum left in me.
Is your body alright?
Sorry, I went on about how I’d make you feel good, but in the end, it was mostly me that was feeling good.
Heroine: Don’t worry about it. I felt good too.
I see. It’s fine as long as you felt good too.
Let’s rest for a bit.
Heroine: Can I ask you why you came back?
Eh? “Can I ask you why you came back”?
Haven’t I come back to see you a couple times before? Though not seeing you in 4 years, that was a first.
After leaving the house so that I could forget you and find a new me, I experienced a lot of things.
I found other places of belonging aside from here, but each time I felt a weird sense of discomfort, I’d run away because I felt something didn’t match.
I continued to live that way and next thing you know, I’m turning 30.
And having reached that milestone age, I stopped knowing who I was anymore.
With all the symbols that adorn me, none of them defines me.
Heroine: Big Brother is Big Brother.
“Big Brother is Big Brother”…….
You’re right, I’m your big brother. Perhaps that’s all I needed to signify my person.
I’ve been struggling to be something I’m not, but…
Who would’ve guessed that the most important thing was something I had from the start? I’m such an idiot, aren’t I? To have realized that now after losing so many places of belonging…
Heroine: I’ll become Big Brother’s place of belonging.
Eh? You’ll…become my place of belonging?
Perhaps it was inevitable that we were attracted to each other as siblings
Surely, that’s how we were made to be when we were born.
Track 4: Can I Be With My Annoying but Cute Big Brother Forever?
Morning. Are you ready?
Is that all you’re planning to bring along?
Then, together, let us go.
