Yahallo~!
(By the way, too hyped for season three of Oregairu)
So this one was requested by @shuzuuki ! (I just noticed I didn't write your name correctly and I capped the first letter) Thanks for your request !
I did my best to make the reader seductive. In fact, it's much harder to write than drawing lol. For the siscon part, I don't know if it's exact but I did my best too by following a certain anime with a little sister who has a brother complex.
I also break the logic of age so try to ignore it or else, you will die from getting lost.
Right now, it's 12:34 am and as always, I'm tired. ( >~<)
Anyway, I hope you will like it and see you at the end !

- Your POV -
"I'm finally here..."
Today is my first day at this school and I was looking forward this day. I was in an another high school but I was forced to change because I spent my time to seduce my classmates and teachers rather than learn their boring lessons.
I live on my own since I got into high school because I don't want my parents and my sister to find out I spend my time to seduce anyone. It will ruin their expectation toward me.
I see some students walking through the entrance gate and some of them were looking at me and blushing. I'm sure it's because of my old school uniform I forgot to give back.. What I did is I loosened my collar size (?) so they can see my flat but pretty chest covered by a bra (Flat is Justice) and I shortened my skirt so people can peek to my panties. People told me I'm quite a lewd girl but it's not my fault, it's because of my parents and their lack of attention for me and more importantly, my friends who gave me some...lewd things.
Anyway, I need to search my new school uniform. If I remember correctly, I have to see the Principal first.
- In a classroom -
- Umi's POV -
I am with Honoka and Kotori and we speaks about stuff. I hope today will go well.
"Hey ! You see that ?" I caught one of the classmate talking with someone.
"Yeah ! The new girl ? She has such a beautiful blue hair but the way she wears her uniform..." The other one said.
"She's pretty or even more..." The first one said and started whisper something to her friend and they laughed.
"Maybe she's Umi's sister ?" Her friend said and I suddenly blushed.
Why did they make me remember of my little sister, (Y/N) !?
"Umi-chan ? Are you alright ?" I heard Kotori asking me.
"I-I'm fine !" I told her without calming myself.
Okay, first let's calm down.
I don't think she's coming here because my parents told me she's living on her own because the school she chose is far away and she had to rent an apartment. It made me feel sad because...I think I'm madly in love with her.
A few years after I was born, she was born and I was happy because I won't be an only child anymore. Until she was ten, we spent together like literally. I didn't let her alone except for private business obviously and we always slept together. I remember when she got twelve, I noticed I have fallen in love with her for her pure and kind personality. Out of all the people, it has to be my own sister I have to love !?
I tried to hold back my confession to her but I can't deny the urge to see her and have her clothes and—what am I talking about !? I-I'm not a siscon !
I sighed mentally.
But one day, when I started my year at high school, our parents told me to focus on study and prepare myself to inherit their dojos. I feel like it's hard to bear and I won't stay with (Y/N) anymore but I have to. Since then, I have started to become serious and I felt less happy because I spent less time with my little sister, like I became an only child again. I hope she's not sad to not be with me anymore...
- Your POV -
I finally found the Principal's room on my own. It took me five minutes to find it because nobody is here to guide me. I thought it would take me like fifteen minutes and someone would take me to this room but I didn't expect to find it sooner that expected.
I knocked the door before I heard a pretty and serious feminine voice telling me to enter. So I did and I encounter an ashed-haired woman. Didn't I meet her before ?
"Oh, you must be the new student—" She stopped to talk when she saw my school uniform.
"Oh sorry. I don't have the habit to fix my clothes." I lied and she sighed.
"You need to fix it from now. For now, you will wear this one." She put the school uniform on her table and blue sky ribbons with red wine strands.
I picked them and I went to the toilet to change my school uniform. I put my old school uniform in my bag I start to put the new school uniform. I wonder if I should take the shirt too... Nah, maybe I can find someone to seduce today
...And here I go !
I looked at myself on the mirror and I feel like I became someone else. Of course it would happened because I can't change some parts of the uniform. I guess I will stay like that and I will hide my visible bra by closing my vest or else, I will get in troubles on my first day.
I left the toilet and I met someone. A red haired girl who's wearing the same school uniform and the same ribbon.
"Are you the new student ?" She asked me.
"Yes, my name is Sonoda (Y/N)." I told her my name and her eyes widened. "What's wrong ?" I asked her and she shook her head.
"N-Nothing. I will lead you to our classroom." She said and I followed her to my classroom.
When we got there, she told me to stay in front of the door and wait for the teacher's calling.
"Okay everyone." I can hear the teacher talking behind the door. "Today, we got a new student. Come in." She said. I open the door and I enter into the classroom.
"Hello everyone. My name is Sonoda (Y/N)." I introduced myself normally to avoid any trouble. I see everyone have their eyes widened and their mouth opened except the one who escorted me. I noticed there's only girls. It will be hard to find someone to love but at least, I'm bisexual so I don't mind it.
"O-Okay, you can sit next to Nishikino-san." The teacher told me and the girl who guided me before put her hand up to show me where she is.
I go to my seat and I hear everyone talking about me but one of their conversation caught my attention.
"Don't tell me she's Umi's sister ?"
"I wonder if she already knew it ?"
'Umi onee-chan is here ?' I thought before I giggled. It brings me a lot of memories. For now, I need to be used to my new class.
- First break -
After the lesson ended, my classmates went to me and asked me where I was and if I'm the little sister of onee-chan. Of course they should notice it because of my (L/H) blue hair except if she dyed her hair which I think it's impossible.
After a while, I see Nishikino-san coming from the crowd.
"Hey, the teacher told me to show you our school. N-Not like I want it." She said.
'Is she a tsundere ? I thought it only exists in novel, manga and games' I thought. 'Maybe I have started to get a liking for her...'
- In a corridor -
Nishikino-san is showing me the school and I notice it's quite pretty both outside and inside. My old school is quite...normal and plain.
We are on the 2nd floor and she's showing me the classroom.
"Here's the classroom for the second years." She told me and I nodded in understanding. "Do you have any question for now ?" She asked me and an idea popped up in my head. I smirked and I started to talk :
"Yes. Did someone tell you you're quite pretty ?" I told her and I can see some cute blushing on her face.
"W-What are you talking about !? P-Plus, it doesn't have any linking with school !" She shouted. "...N-Not like I care about your commentary..." I heard her muttering.
"Ah Maki-chan !" We heard someone calling and Nishikino-san reacted. I supposed her first name is Maki. Well, it will give me an advantage for later.
- Umi's POV -
We talked like we usually do and we suddenly hear: someone shouted. This voice is no other than Maki. Is she having trouble ?
"Maki-chan ?" Honoka asked.
"Maybe she's in trouble. We should check it out." I told them and they nodded in agreement.
We left the classroom and we saw Maki from behind. While we're walking toward her, Kotori and I heard Honoka calling her loudly. Maki heard her and she turned to us and I noticed there's someone else behind her. This person peeked at us from behind Maki.
'This blue (H/L) haired and those (E/C) eyes.' I thought and I suddenly feel my heart beat faster. 'I-It can't be—!'
"Ah ! Onee-chan !!" She called me and she ran toward me and hug me suddenly. This cheerful voice and this familiar voice. It's without doubt my little sister, (Y/N).
- Your POV -
I'm happy to see onee-chan again ! It's been a while since we didn't see each other. And—
"Onee-chan, why are you blushing and...is it blood coming out from your nose ?" I asked her after I notice it. Her eyes widens and she hides her nose with her hand.
"N-No ! I-It's nothing !" She said and I see Maki sighed and she gave her a tissu.
"So what are you doing here ?" I asked her on purpose. I'm sure she still thinks of me as a pure girl.
"A-Are you idiot ? I-I study here." Onee-chan said and I giggled. "And you ?" She asked me back.
"Well I study here from now !"
- Umi's POV -
I-I can't believe what she said. I-I mean, I'm happy to know she's going to study on the same school as mine but seeing her everyday will make me bleed from my nose. Urgh...why do I love her ?
"Ah (Y/N)-chan ! It's been a few years we didn't see each other !" Honoka said and (Y/N) look at her.
"...Who are you ?" She asked her.
Ah, that's right. It's been like X years (Y/N) and I met Honoka and Kotori. I had stayed with them until now but (Y/N) did for one day. After, she had to stay at home for reasons I don't know yet.
The bell rang up and we departed toward our respective classroom and I was about to walk but I felt my sleeve tugged. I looked behind and I saw (Y/N).
"I'm glad we can finally be together !" She said and my heart suddenly got faster.
'D-Don't think about it implicitly ! Don't think about it !' I tried to calm down myself.
"I-I'm glad too..." I stuttered. She looks at me confused but she shakes it off and she smiles and so she left.
I'm walking to my classroom and I prepare for the next lesson.
...
..
.
During the lesson, I can't help but think about (Y/N). It seems she didn't change at all except she got prettier than before. Just thinking about it makes me want her right—
"W-What am I thinking ?!" I suddenly yelled out and I see everyone surprised. "A-Ah sorry..." I tried to not look at everyone and the lesson continues.
'Why does (Y/N) has to be here...'
- Lunch time ~
- Rooftop -
I am on the rooftop with Honoka and Kotori to eat with the others members of Muse. While we're talking, I notice the first years are not here yet. Maybe they have something to do first. We waited them until we hear the doors opened and we see the first years coming with their lunchbox.
"Sorry for the late nyaa~! Rin said.
"I-I hope we didn't make you wait." Hanayo said.
"It's because of her." Maki said annoyed. Her ?
"Ooh~! Is it where you usually eat ?" I hear this recognizable voice. I got up and I looked at them.
"W-Why are you here !?" I yelled after my eyes laid on my happy little sister.
"Eeh~? But I really want to eat with you..." She pouted.
'U-Ugh...! How could I forget this cute pouting !' I thought and I decided to not look at her.
While the first years are taking their place, Nozomi comes at me.
"Who is she ?" Nozomi asked me.
"W-Well...she's my little sister, (Y/N)." I told her while trying to not glance at her. Nozomi looked at me and then at (Y/N). Why is she looking at her ?
"Hmm...by looking at her. It seems she's hiding something~" Nozomi said and I can see her smirking. I check (Y/N) and she's happily talking to the first years. I'm quite glad to see her getting already used to this school but why Nozomi told me that ?
"Why did you tell me that ?" I asked her and she didn't say anything but she looks surprised by what she's seeing.
"Maki-chaan~!" I heard (Y/N) calling Maki. I look at her and (Y/N) is on her four legs and she holds a piece of her meal in front of Maki who got surprised. Something started to trigger me.
"(Y-Y-Y/N) ! W-What are you doing !?" I and Maki said at the same time while we're blushing. Why is Maki blushing ? Maybe it's quite embarrassing but even so, I wish it could be me instead of her.
"I want to feed you !" (Y/N) said while smiling at Maki. "Now, say aaah~" Didn't she hear me ?
I see the piece of meal between (Y/N)'s chopsticks getting closer to Maki's mouth. Maki hesitated whether to eat or not but she gives in. Something awaken within me. One part of my mind told me to not interfere but the other part wants me to eat it.
Feeling the adrenaline flowing through my vein, I put my lunchbox on the floor and I immediately ran toward (Y/N) and Maki. They looked at me surprised and I immediately ate (Y/N)'s piece of meal.
'I-It's delicious !' I thought as I'm savoring it. The taste is so marvelous. Did she cook it ?
"H-Hum...Are you alright onee-chan ?" She asked me.
"Y-Yes !? W-Why ?" I asked her back while blushing and trying to not look at her. Gosh, it's difficult to look at—wait a minute !? Why can I see her bra from above !?
"Well, you ate the bit which is supposed to be for Maki-chan..." She said without worry about her visible bra. Oh god, why is she so pure ?
- Your POV -
I was surprised when Onee-chan suddenly ate the bit destined to Maki-chan. Her behavior was quite different than I knew but she seems to like my cooking by looking at her reaction.
I asked her if she's alright and I noticed she was looking at my bra. Of course, I unbuttoned the vest because it's quite hot today. I noticed she madly blushed and I nearly gave in to seduce her by showing her more my bra but I shook it off and I acted as the innocent (Y/N). I still don't want to ruin her vision of me and plus, I don't want any troubles with the others
I look at Maki and she's blushing. Oh god, I want to tease her again~
- Time skip : The next day -
- In the classroom -
- Umi's POV -
I'm quite tired today.
Yesterday, I couldn't focus on lessons because I couldn't help but think about (Y/N). Is it getting worse ?
"What's wrong Umi-chan ? You don't seem yourself." Kotori asked me worried.
"I'm fine." I told her. "It's just about (Y/N)." I let it out without noticing.
"Eh ? Did something happened between you and (Y/N)-chan ?" Kotori asked me once again. Why did I tell her like that !?
"W-Well...you see—" I was about to finish my sentences before I hear someone running.
"Oneeeee-chaaaan~!!" This voice again...Please, my heart can't bear it anymore !
"What is it (Y—" I stopped to talk when I saw her clothes. Her skirt is shortened to near her hips, her ribbon is loosened and I can see her visible bra but more exposed that yesterday. What happened to her !?
"U-Umi-chan !? Are you alright !?" Honoka suddenly asked me worried.
"I-I need a break !" I told her and I immediately left the classroom.
- On the rooftop -
I'm trying to relax my mind. I nearly got knocked out by seeing (Y/N) in this—s-shameless condition !
Don't tell me someone is bullying her ? It can't be—
"Ah Umicchi~" I hear Nozomi calling me. "What are you doing here ? The first lesson will start soon." She told me. Maybe I should tell her about (Y/N)—no ! I want to protect her by myself.
"I-It's nothing !" I lied to her and I looked at her. She looks confused.
"It's looks like you're lying." I heard the voice of Eli. She comes out from behind Nozomi.
"N-No I don't lie !" I said while trying to keep my calm.
"Don't lie to us or else~" Nozomi said and I see her hands moving weirdly toward me. Oh no, I don't want to get it. I mean, I want to keep my first time for (Y/N) and—what am I thinking again !?
"O-Okay ! I will tell you !" I immediately gave in to not be a victim of her...actions.
Nozomi's hands stop moving and she and Eli giggled until they get serious and look at me waiting for my answer.
"I-It's about (Y/N)..." I admitted it. "H-Her clothes are...you know..." I tried to not say anything shameless but they don't get it except Nozomi who's smirking. Looks like she guessed it.
"Really~? I think it's fine. After all, it's her choice." Nozomi said.
"Nozomi. I don't know what you and Umi were thinking but modify the school uniform is forbidden except if we give them authorization." Eli said.
"Y-You're wrong !" I told her. "I-It's just..." I hesitated. I really want to tell them about my little sister getting bullied but I don't want to make it worse.
Driiing Driiing
"I guess it's time to go to our classroom." Nozomi said and started leaving.
"Well, see you later." Eli said and she's walking away until she looked at me. "If you need to tell us about your little sister. Don't hesitate." She released a smile and left.
- Nozomi's POV -
The talk with Umicchi made me confirm something which is she loves her little sister. I already guessed what she wanted to say because I met (Y/N)cchi in the council student room to tell her about school stuffs. Elicchi was with Kotori's mother to talk about some upcoming events.
When I saw (Y/N)cchi in her new uniform, I didn't mind it because I already expected her to do that. How ? Of course with my cards—just kidding, I saw her on her first day through the window of the classroom during the first lesson. The moment I saw her, I knew she's Umicchi's sister. I wonder if she likes her back ?
"Hey Nozomi." Elicchi called me. "Do you know something about (Y/N) ?" She asked me. I don't say anything for a while.
"No, I don't." I lied to her.
For now, I need to help Umicchi to confess to her little sister. I don't mind the incest thing and I'm pretty sure she loves her a lot because she blushes a lot when she talks about her and she ate the bit of (Y/N)cchi's meal who's supposed to be for Maki-chan surely because of jealousy.
(This is where I got troubles to write)
After a while, I suddenly got an idea. If I remember correctly, the info about (Y/N)cchi told us she lives on her own and today is Friday which means she will have to buy foods tomorrow. Maybe I can drag Umicchi but the problem is where does (Y/N) buy ? Maybe I need her to tell me.
- Timeskip : The next day -
- In a mall -
- (Y/N)'s POV -
I'm actually buying ingredients for the next week. Yesterday, Nozomi asked me if I have any mall I recommend. I didn't trust her but when she told me she lives on her own too, I understand her and I told her.
While I'm walking, I noticed someone is following me. I hope it's not a pervert or a rapist. I kinda regret to let myself defenseless and gave in into wearing sexy outfits.
- Umi's POV -
I am in a certain mall because Nozomi told me there's a book I can be interested but I didn't expect my little sister being here too but what's shocking is she's letting too much of her skin. I nearly got nosebleed but I managed to hold it back. I asked myself why is she wearing like that ? It's not the little sister I used to know but...I think I don't mind it even if it's shameful. Maybe I love her—no, you can't ! It's still not normal to love someone from your family romantically.
Normally, I could go to her and talk like we used to and even ask her but I don't want her to find out I was spying on her and at the same time, I want to see and learn how she's living. Now, I'm actually hiding behind a corner of a shop.
"Hey look at her !" I heard someone talking next to me. I can see two men looking at (Y/N).
"Don't you think she's so cute ?" One of them said.
"Hell yeah ! Let's try to hit on her !" The other one said and they started to walk toward her.
I really want to stop them because I don't like what's gonna happen next. Good thing I brought my wooden sword in my bag. Why do I have it ? Because I'm a member of Kendo club too.
I got closer to them while still hiding behind a corner and I listened to their conversation.
"Hey girl, what are you doing here ?" One of them said. Both of them are wearing such a disgusting face while (Y/N) is confused.
"I-I'm buying stuff." (Y/N) told them nervously.
"Oh, well why don't we join you ?" The other one said.
"O-Oh, it's nice but I'm kinda in a hurry...!" (Y/N) said and started to leave but one of the men grabs her wrist. I feel my anger growing within me and I bring my wooden sword out of my bag and I suddenly
"Oh really, why don't—" I suddenly left my hideout and I intentionally miss my attack to scare them.
"What do you think you're doing ?" I said as I prepared myself for an eventual battle. "Don't you dare to lay your hands on my little sister !" The two men got scared and they ran away.
I look at my little sister and I can see her tears getting close to leak out from her eyes. I guess she got scared.
"Are you alright ?" I asked her while I swipe her tears.
"O-Onee-chan !" She shouted while crying and she hugs me. I kinda missed this feeling.
We went to a park and we're sitting on a bench. I'm kinda nervous because it looks like a date.
"So..." I initiated the conversation.
"T-Thank you onee-chan..." (Y/N) said nervously. I can tell it's her first time to be save by someone especially by me. "I'm kinda scared when people talk to me and try to hit on me. I'm supposed to be the one to do that..." She said and she looked away. "Onee-chan, do you dislike that side of mine ?" She looked at me while holding back her tears.
"Of course not." I reassured her as I patted her head. "I love every sides of yours." I continued and she's starting to blush.
After that, I follow her and we talk like we usually do but I notice she's blushing a lot recently. I hope she's not sick.
- Your POV -
My heart can't stop going crazy when I'm with onee-chan. I wonder why ? The way she saved me is so cool. Even though I wondered why she is here, I don't mind it because I'm grateful to her. Plus, she even accepted my seductress' side. I expected her to tell me to stop it but she—
"(Y/N) ?" My heart suddenly beat louder when I heard onee-chan calling me.
"Y-Yes !?" I called back panicky. How can I stay calm now ?
"..." She didn't say anything but she grabs my hand gently and so I blushed again. "Can I come at your home ?" She asked me. I hesitated but I think I can let her go because I want to thank her properly. So I nodded at her and I continue to buy stuff along with my onee-chan.
- An another time skip -
- At your home -
- 3rd POV -
You and Umi finally got into your apartment after a few minutes of shopping. Your apartment is quite normal like you usually see.
You're starting to get your shoes off but Umi didn't do anything and she's just staring at you. You noticed she doesn't make any noise so you look at her.
"Onee-chan, what's—" You were interrupted after your sister pinned you to the floor. You can feel your heart going crazy again and you can see Umi's serious expression.
"(Y/N)..." She called you and you can feel your face heat up. She brought her hands around your neck and she pulled her head next to yours.
"O-Onee-chan...?" You tried to ask her about her action but you can feel her hands trembling.
"W-Why...?" Even her voice starting to tremble. "Why are you the one I l-love...?" She continued and you hear her starting to cry.
"Onee-chan..." Is all you can say. You understand her because it's quite a taboo for someone who loves her siblings romantically. But when you hear what she said, your heart got fluttered. You think you love her too but...is it really wrong to love someone from your family ? You gulped and you whispered this sweet confession. "I love you too..."
- Extended Ending -
Umi can't believe what you said. She tried to guess if it's a dream or not but she realized it's the reality. She's trying to hold back her tears of happiness but she couldn't. You giggled and you told her to get off of you or else, both of you will stay on the floor and live forever but Umi shook her head and she told you she wants to stay like that. You think she's quite childish within her.
"You know...I-I thought you love Maki." Umi told you and you smiled.
"She's quite cute but you're cuter than her." You said and she blushed.
"G-Geez...Don't talk like that..." Umi said and you giggled.
"Hey onee-chan, when do you start to love me ?" You asked her. She looked away and she blushed.
"S-Since when you were born..." She told you embarrassed.
"...you lolicon and siscon. In fact, you're a loli-siscon." You said and Umi's eyes widened.
"Y-You're wrong !" Umi said while backing up and waving her hands. You giggled and you noticed shadows through the door's windows.
"Huh...Onee-chan ?"
- Meanwhile : Outside of your apartment's door -
"Wait, let me see it."
"Don't push like that !"
Meanwhile, there's some girls who's watching the whole scene between you and your sister.
"They look so cute together !" Kotori said.
"Yeah ! I'm sure everything is going to be al—!" Honoka talked until the door opened and the eight girls fell on the floor.
"So you were spying on us...?" Umi said darkly and the girls got frightened. They look at you but you told her by doing signs you're sorry.
"Y-You're wrong Umi-chan..." The bread lover said and Umi got mad and she started to run after them.
What a good ending I guess ?

- Nanase Ririna x Ex-Perverted! Serious! Cold! Female Reader (From I•outo P•••••••) (I wonder if it's useful to censor the title because people can find the character on the Internet) -> An angst one-shot too I guess or the first one-shot from an eroge.
- Yandere! Kisaragi Chihaya x Female Reader x Amami Haruka (From IDOLM@STER) -> obviously a yandere one-shot.
I will let you choose for now which one I should write first and meanwhile, I'm gonna brainstorming ideas for the Remilia's one.
