Only ours yandere twins

Kai and Nai's POV

(Pic of Nai and Kai in school above)
When we finished killing the stupid girls we changed into some new clothes and washed the blood off. We disposed of the bodies and went back to class.
"Have you seen Y/N" the teacher asked and Nai and Kai looked at each other.
"Mei-chan she must have seen" they bolted out the classroom and ran outside the school jumping the fence.
"Where could she have gone" Nai asked Kai
Kai was furious and started dragging Nai when he saw this car take off.
"Wow that lady must have been in a rush" Nai said as he watched the car zoom off. When the car was only a speck he saw something move in the back.
"Is that Mei-chan" Nai asked Kai and Kai shook his head
"Let's starts looking" the two searched everywhere across town they asked everyone and got nothing. When they reached home they stormed into their parents office.
"Mother Father this is an outrage" Nai yelled
"What seems to be the problem boys" their father asked sarcastically Kai held back his anger
"Mei-chan is missing duh" Kai yelled
"Don't raise your voice young man" their mother said
"She doesn't care for Mei-chan" Kai made a fist
"I'm sure you just misplaced Mei-chan or threw her away or something we will get you another Mei-chan" their Father said before making a phone call "see problem solved"
"What do you me-" just then a little girl with brown hair and green eyes came in
"Boys this is Asura call her Mei-chan" their father said
"She's not Mei-chan" Kai yelled "she's a pitiful ugly toy"
Asura broke down in tears.
"Boys that is rude" their mother said shaking a finger
"And" Nai said bored
"Fine at least come see what we made today for you" the two parents followed their twins living the stupid, weak, Asura alone (remember this is how the twins see her).
"Where is it" the two parents were at the top of the long case of stairs they looked around to see the boys gone.
"Kai Nai stop playing g-" the mother screamed as she was pushed down the stairs her counterpart soon following their deadly and painful state.
After tumbling down what seems to be about 50 stairs they fell at the bottom in a pool of bruises and blood. Nai and Kai high fived each other at the top is the stairs. They saw Asura come out the room while Nai dialed the police. Kai grabbed Asura and dragged her into the twins room.
"You're much to ugly to be Mei-chan" he said pulling her short brown hair towards him. She winced in pain.
"And you're such a baby" he replied "maybe I should kill you"
Asura broke down in tears her mother just left her here and now this boy is insulting her
Suddenly Kai kissed her and she melted but wasn't expecting him to bite her hard. He let go and she cried out in pain.
"It's your fault that you're ugly you deserve this" Kai yelled putting his anger out on her. Then he pulled a library book back and the bookshelf slid open.
He dragged Asura by her hair into a secret room where the door behind him shut.
"I'm going to torture you silly" he chuckled darkly

Meanwhile Nai had called the police and they were soon investigating the scene.
"what happened" asked the policeman
"My mother was holding on to my father and slipped and fell bringing him down with her and they didn't move when they reached the bottom" Nai began to produce fake tears and sniffle
"It's alright we will be sending your Uncle over to take you into Custody until you are old enough to take this place over yourself" then they left taking the bodies. Nai laughed wickedly and went into the room to here faint panting. He opened the secret entrance and walked into the room to see Asura underneath Kai crying seeing the fact she had a ummm....... Dildo in her well actually several.
"Oh hi brother" Kai said and Nai sighed "she doesn't deserve a real one so why not"
Nai chuckled at his brothers response and pushed him off the girl.
"Thank you" Asura whispered as Nai helped her up.
"Oh I'm not helping you" he said pulling her to the wall chaining her this secret room was a dungeon where they break all their "toys"
Asura sobbed hard as the two tortured her this would go on for weeks days even unless she learned to be a good "toy" then she could go to school.
We will find you Mei-chan don't think you've escaped
