YANDERE FEMALES X MALE READER

Yandere sister x brother reader

(Y/n's pov )
I was awoken to another lovely morning with the sun shining and the bird's chirping outside but as i get out of the bed i heard footstep's running to my room and then suddenly

*slam*

My room door was slamed open by my 18 year old sister clair l/n you know sometimes i wonder who is truly the older sibling since she can act childish sometimes but she's my sister i don't care if she acts childish i still care about her  anyway getting back to it

(No ones pov )

The two siblings could be seen in the same bathroom brushing their teeth as well as talking

Y/n : why do you have to do that every morning just to wake me up you know there is something called knocking you know

Clair : aw but i thought that was our special thing that we did in the mornings

Y/n : ya anyway today is finally the day i get to tell elena that i have feelings for her

As y/n was talking to himself about confessing to his long time crush his sister clair was looking at him with blank eyes she griped her tooth brush so hard you would think it would break anytime soon and to say she didn't like the thought of her brother being with other women was an understatement

Clair * thoughts * " it seems some parasite wormed their way into my beloveds life and we can't have that now can we "

And with that they finished brushing as well as getting them some breakfast they soon head off to school and clair with a goal in mind

Clair * thoughts * " it seems to me that i need to get rid of that parasite once and for and only then will my beloved brother be mine "

With that thought and with a plan in forming in her mind clair with blank eyes and an insane grin on her face went with her brother to school where their most of their time will be spent

It was time for a lunch break and away from the work that the teachers would normally give them and we can see y/n walking with a purpose towards a girl with blond hair and green eyes when he reached the table could hear the other students talk

Student 1 : wow he is one brave guy talking to her

Student 2 : nah i just think he's crazy if he thinks he has a shot with her

Student 3 : well guy press f to pay your respects cause we about to another one crash and burn

With all of them talking negatively didn't help y/n's nerves so he just breathed in and out to calm himself down and started to talk to her

Y/n : hey uh elena i wanted to ask you something

Elena : yes what is it y/n ?

Y/n : will you go out with me

Elena : if you want my honest answer i don't like you like that and i never will it's nothing against you it's just i see as a friend i'm sorry y/n

Hearing that not only his crush didn't have the same feelings as him but admitted that he was nothing more than just a friend hurt y/n bad but he didn't show it but what they didn't know was that someone saw and heard everything that happened

Clair * thoughts * " oh y/n i knew that slut was no good for you but to think she would hurt you like that don't worry my love i will get rid of that insect that hurt you and then we will be together forever and ever "

Those were the thoughts of clair l/n who had a blank sadistic look on her face

As the day came to an end clair stood infront of the gates of the school and she saw her brother come walking on with a depressed look on his face which pissed her off further but she quickly changed her expression to a concerned one as she approched her brother and with a worried tone asked him
