yandere valkyrie oneesan

>Yandere Valkyrie Onee-san
You've been adopted by a family in MGC. As you ride the cab from the orphanage to your new home, you wonder how your family would be like.

To your surprise, it's a Valkyrie family. You are introduced to your new family members by your Social Security worker. You approach your new family. They seem nice enough. But one person stands out. The daughter, who is staring at you very.... oddly. You greet your family with a smile. First impressions are important. You quickly unpack your bags across your new room. Tired from the excitement of a new family and a long trip, you collapse on the bed.

You wake up to a startling shake. Your new father is waking you up. You manage a barely intelligible response as you try to stop the shaking. "Wake up! It's time for breakfast." hearing that from your father you wake instantly. You run from your room and bump into the wall. Shit, you have to remember the structure of the house to create a optimal quick breakfast route. Your mother is cooking a very delicious something? You don't know what it is but it smells delicious.

When you asked your mother about it, she said that it was some zipanguese stew with some custom made side dishes. Food is still food as you think to yourself and begin eating.

"Going off to work already?" your mother says as your dad runs out half dressed with some coffee in a thermos. Your dad nods his head as he is rushing to the car. You ask your mother about your dads job. He works as a professor in the prestigious university. Huh. You expected something along the lines of something a paladin or a 'hero' type would do.

The day passes on as you fill out forms and get shots to transfer to your new school.

(sorry for the slow development and almost non existent appearances of the onee-san)




A couple of weeks go by and you get adjusted to your new life. You get used to your new family. You quickly learned that your mother rarely cooked since she worked as a company worker in a minor law firm.

So your sister mainly made you lunch. She was a bit weird during your first introduction but it turned out that she was just a bit shy. She loved cooking and books.

It was a common subject that you both loved. When you came home you and your sister would always read books together and talk about the books since you had nothing else to talk about. You didn't know anybody at the school. You being naturally wary of people and the confusion of a new environment, you were pretty isolated. The only time where you could release all that frustration was talking with your sister. She was really empathetic and caring. She always took care of you, always tutoring you on subjects that you found difficult. The epitome of an older sister.

Still she was a bit odd. When she dropped her pencil from taking notes and you picked up her pencil and gave it to her, she was breathing a bit shallow. She was in the bathroom for a long time after that. Also when you hugged her, hee breath sounded like she was panting and she gasped very sharply when you did that. She would always insist on watching me sleep and sometimes my sweaty clothes would disappear, and be found in her bed.

You slowly socialized with some people at your new school as some time passed even more. You became friends with the other book club members after deciding to join their club. The club was pretty small. With a manticore and a dormouse, it was a very small club. After your first day joining the club, your older sister came up to you with a worried look on her face and said, "You shouldn't be close to those girls.". "What girls?" you ask your sister. With her lips trembling she says in an angry tone, "Those girls in the fucking book club." You look at her with a shocked face. You've never seen your sister use such harsh words like that. "I'm sorry. I'm just worried about you is all. You know, a boy shouldn't be in a single room filled with girls. I don't want something bad to happen to you." she sighs as she replies in a slightly apologetic tone. Well after that incident, your sister made you dinner and you quickly went to sleep after that.

You woke up to heavy panting. This was too early in the morning. You groaned out "just a few minutes more....". Then a gasp was heard and you could hear something crashing. Now that got your attention. You quickly jumped out of bed, worrying that an animal or even worse a thief was intruding your room. Nothing was there. But the picture of you and your older sister was knocked down along with your clock. Your finger was cold with some ... sticky goo covering it. The carpet was also wet with some fluids of some sort. Dismissing it as some sweat and some ceiling leakage you quickly go to the kitchen to get some breakfast. Your sister was pouring blood droplets in the milk that you drink. Confused, you quickly ask your sister what she is doing. She replies blushing "I read from a book that it helps a person's true love find them." You look at her with a confused look. Well, your sister was always weird. Something like this was certainly not out of the place. You eat your breakfast albeit a bit hesitantly. But your sister eagerly looks at you to eat your breakfast so you reluctantly do so. You finish your breakfast and head to school with your sister.

Choose (cause I ran out of ideas)
1. Mild yandere (Forcibly raping you and mindbreaking you)
2. Extreme yandere (Tying you up in the basement and constantly raping you)
3. Gore yandere (Chopping your limbs so you can't run away or shit like that)
4. Something completely else (Your choosing)

Three months have passed. Ignoring your sisters advice, you continuously met the members of the book club. Contrary to your sister's opinions the members are one of the nicest members you'd ever been in the company of. You could be more open with them than you could ever be with your older sister. Also being in the same classes with you, you always were in their company. You weren't lonely anymore. But the more your happiness grew the inverse applied to your older sister. She became more passive-aggressive and more brooding. The members of book club became closer and closer. You and the members talked more at school and even meeting each other after school and just talking about school and books. You told your older sister that you were going to to the library. If you told them that you were going to meet your friends she would just nag you and you weren't technically telling a lie anyways.

You came back home with a recent trip from the 'library'. You were thinking about how your mother and father wouldn't be here because of their vacation to some tropical island. You enter your house. Your sister was humming something along. She was awfully in a festive mood today. She was in the kitchen cooking something. You think that this is the first time that she was in this mood in about three months. But something felt artificial. Maybe it was her sudden mood change over three months but, her smiles felt too forced. She was 'accidentally' touching you and getting close to you. She was also talking about how she was perfect for you and you were perfect for her. Weird shit like that. You could have sworn that she put some pills in the soup that she was cooking. No, that couldn't be it. Despite what they said at the mandated rape prevention seminars at your school saying that close family rape is the most common especially among older sisters and little brothers, your older sister could never be like that. Your older sister would never take advantage of you like that. She finally seemed like she finished her dish. She came to you in an almost gleeful joy skipping along the best she can while holding a bowl full of hot soup. She placed it down to you urging you too eat it. You eat the whole bowl of soup.

You slowly begin to feel dizzy. The ground is spinning and you feel so sleepy. Your older sister catches you as you slowly fall on the ground. ""Don't worry, your older sister will take care of you. Your older sister is all you need. All you need...."
--------------------------------------------------------------------------------------------------------------------------------------
SUFFERING BEGINS(No worries. Might go down to a healing route if you so wish)

You collapse on the floor. Strength rapidly leaving through your fingertips like a fast pouring current from your limbs to your fingertips. Your sister picks you up and places you on her shoulder with her arms wrapping around your back and your head hanging next to her own. She picks you up and carries you up the stairs. She heads directly to your room. She gently places you on the be and she sits down on the side of the bed, careful not to sit on you. Her face is blushing and her head down as she is trying to say something. "I... I've always... You know I......" She continuously falters on what she says. After a few tries, she finally says something. "I've always loved you. I didn't realize when I first met you, but I loved you nonetheless. I was almost always alone in this house for a long time. Mom and dad were always busy with their jobs and I never seemed to need a baby sitter. It's not their fault. You know, waiting for mom and dad to come home in an empty house..... it made me feel lonely. I never really had friends since I never socialized all that much, so I never had friends over or talked with people at all. I always read books to pass the time.

There was this book that I read called the 'Countess the Clock worker'. As she said that name, a warm smile spread to her lips. It was about a lonely countess who lived in her mansion with thousands upon thousands of books. One day a clock worker happened to visit her mansion. It was the first time in years someone came to her mansion. The clock worker fixed the countesses's clocks and began to leave. Not wanting her first visitor in years to leave, she urged him to stay. She and the clock worker talked about many things. The man would teach her of the outside world and she about the beauty of the worlds she experienced. These talks became longer and longer and eventually progressed into romance. But people noticed that the clock worker was spending too much of a long time in the countesses home and began to spread rumors. Especially her relatives. The countess had a lot of money and they were worried that if she became close to the clock worker, the clock worker might make tell her about how they were abusing the people of her lands for their own gain. So they began pressuring him. The story went on and eventually the clock worker lost everything but the countess. The countess protected him and comforted him.

I longed for someone like the clock worker everyday. To help me break this stillness of loneliness. To have someone to love and laugh with. I prayed to the gods everyday to bring the clock worker to me.  I laughed at my own foolishness about wishing for the clock worker. I had read enough books to know that would never happen even if the clock worker came to me. The day you came, I was excited. I thought it was from having someone to talk to while I was lonely but I knew deep down that it was something different. I still denied the dream of the clock worker thinking that it was a foolish fantasy. But as time went on I began realizing that you are my clock worker. You are the gift god sent to me. And everyone else is in the way. Oh, they might not show it but each of them hates us and wants to take you away from me because of THEIR own selfish wants. They will do everything to try to separate us. At the end of the story the clock worker kills himself unable to deal with the pressure from all the bad people even with the countess at his side.

I don't want that to happen. I don't want to lose the only thing that I value. That's why I was angry at you for not understanding me. Those FUCKING WHORES AT YOUR CLUB AND EVERYONE ELSE HATES US AND WANTS TO SEPARATE US. I CAN'T FUCKING LET THAT HAPPEN. But I still respected your choices because I loved you. BUT YOU FUCKING LIED TO ME. YOU SAID YOU WERE GOING TO THE LIBRARY BUT YOU WERE MEETING THEM. My pure innocent brother was already being caught in the clutches of those harlots tempting you with their words and behaviors. So the only way to reverse the corruption is to destroy any presence inside of you. I have to destroy any traces of their
presence in both mind and body."she finishes with a very excited look on her face.

Her hands trembling, she slowly stretches her hands to your face. "Do you love me?" unable to move your head or your mouth at all because of the thing in your food, you lay there silently. "What's that? Of course I love you, you say? I knew that my cute little brother would say that!"she says with a manic look on her face bordering on insanity. "Well, I love you too. I love you forever forever forever forever forever forever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever and ever!" she repeated until she ran out of breath.

"Since we love each other, we should do something to cement our love in eternity! We should get married...... Oh! I'm positively shaking with excitement! With a wedding dress and a tux in a wedding hall! Going on a honeymoon with my beloved....Living with my little brother with beautiful daughters to raise as our own! How do you feel about marrying?!"She says with her excitement reaching new crescendos. She moves her face to yours and begins to move your lips with her fingers. With her best impression of your voice she says "Marrying with my beloved? A million time yes! I would love it! You're my beloved one and only!" You notice that as you directly stare into her eyes that her fucking pupils are heart shaped with a blank look in them. With a voice only described as absolute ecstasy, she says "Let's get married first thing in the morning! But first since we're basically married, we should do that thing that married coup.......". She blushes a deep red and perhaps unconsciously, her saliva drips out of her mouth. She wipes it and begins to move closer to you. "Why do you smell so good Anon? I feel like I want to experience more of you, taste more of you. Perhaps a kiss?..." She with shaking fingers open your lips. Then she assaults your mouth with her mouth. You can feel the saliva coil around mixing in your mouths. Your tongues intertwine as if trying to subdue the other but while constantly slipping away. You can feel her lips suck on yours with a greedy suction. She rapes your mouth sticking her tongue in every location possible. She traces the roof of your mouth when you feel a low sensual moan escape from her throat and go directly in your mouth. Her groans grow in intensity the more she moves around your mouth and touches your tongue. After a few seconds of mouth rape she gasps into your mouth and slips away. Desperate for air you breath heavily involuntarily at least. Your sister lays there with her right as your side as you lay down. Her face is twitching subtly and she looks as if she is utterly satisfied and with a thin trail of saliva running down her mouth.

------------------------------------------------------------------------------------------------------------------------------------
As she slowly released you from her mouth, you began noticing a trail of black spreading across her skin. It was a beautiful contrast with her marble skin. It started from her and chest and slowly began to spread across her stomach like ink in water, slowly changing her skin. After a few seconds it stopped its pace as if hesitating to go farther. She noticed you eyeing the obsidian stain on her flesh and with quick swipe, she covered it with some blankets on your bed. Her face visibly got defensive and ashamed. The shame wasn't like the blushing from before, where she was excited but rather an acute sadness. It seemed like she was very sensitive about the black spread covering her skin.

"I'm sorry that you had to see that." she said as her voice trembled as if she was on the verge of tears. She quickly turned her back on you and began to hold the blanket to her face. You heard her muffled sobs seeping from the blanket. She was muttering something on to the blanket. "You stupid piece of shit! Now Anon doesn't love you anymore because of your impurity!" was all you could hear her mutter over and over again. After a few minutes of her sobs and muttering "Anon doesn't love me" ,she put down the blanket and began staring at you with empty eyes. With an empty smile devoid of any emotion she said "I'm sorry that you're sister couldn't be pure for you. I love you so so so much and you wouldn't love impure people like me. I'm no different from the whores.......".

Suddenly she stood from your bed and with a unnatural forced grin. She began to say with certainty in her voice "I'll just become pure again to deserve Anon's love. I'll just become pure I'll just become pure I'll just become pure I'll just become pure....." She said as if she was a machine that had a malfunction. She left your room and you could hear loud crashes and broken wood from the room next to you, her room. She walked in your room with a cleaver knife in her hand. "I-I'll show you how pure I-I will b-b-become for you Anon" with that she began to move her hands closer to the obsidian region covering her stomach. With the knife practically vibrating in her hands she brought it closer to her until blood began a drop of red began painting her stomach. She flinched the moment the knife began digging her flesh. She looked at you and began to smile at you with tears running down her face and said "I'll remove this f-filthy blemish to receive your love again.".

You couldn't watch this happening. You didn't want your sister harming herself for any reason at all. You mustered all your will into moving your mouth. As if trying to move lead lips your mouth wouldn't budge. She began tracing the knife around the edges of the blemish. The red began to trickle from drops to small streams painting a stroke of vibrant red on her stomach. No. You tried harder to move those weights on your lips. You didn't want your sister sad because of you and you sure as hell didn't want to hurt her. With all the strength left in your body you managed a small croak "N-No....". Your sister raised her head with a look of utter total confusion. You scraped the very last reserves of your willpower and mentally gritting your teeth. "S-stop. Don't hurt yourself." There were so many words that you wanted to convey but you realized you couldn't in your current situation.

"D-Did I do something wrong? I-I'm sorry... I'm so stupid so stupid." Your sister says as if desperate for forgiveness. Your mouth is slightly easier to move. The drug must have been wearing off. "No you're not stupid.." you reply trying to calm your sister down.
She begins to calm down as you say those words. "Y-You still love me Anon?" she finally whispers as she calmed down. "I love you as an older sister." you reply again in a whisper. A deafening silence fills the house for a few minutes, but it feels like an hour. "A-As long as you still love me, I'm fine with that..." She finally says breaking the barrier of silence. "I-I'm sorry for trying to sully you.... I've failed as an older sister. Forgive me." As she says those words, she stands up and leaves the room. Grateful because you avoided a near rape incident and tired from all the stress, you begin to sleep. Meanwhile your sister has entered her room. She begins to cry, since she has failed her plans into making you her lover and knows that your previous relationship will never be salvaged, knowing that there will be an awkward tension between both of you. "Anon will be my lover someday..... no matter what happens......" Your older sister goes to sleep. You may have been spared this time but, your sister became more obsessed over you, just expressing it in a much more subtle way......
