Only ours yandere twins

Onii-san huh?

The two rushed you into a mansion and quickly gave you a towel. They dragged you into a room which was huge.
"This is our room" they said in unison before Nai ran off into a room. You heard water running and you sighed.
"So what's your name" you were surprised at how soft Kai's voice was compared to earlier
"It's Y/N" you said shyly
"Y/N-chan that's a pretty name" soon Nai came out and the two dragged you into a bathroom.
Kai began to lift up your shirt while Nai began to pull down your pants.
"W-what are you doing" you asked quickly trying to stop them but they were to strong
"We're going to take a bath" they replied nonchalant
"W-wha" sooner than you could blink the three of you were in a bubble bath undressed. They smiled at you.
"Nai Kai-"
"You can call us your Onii-sans" they replied
"Onii-sans" they nodded " why did you take me in no one wanted me not even my mommy" a tear slipped down your cheek and Kai licked it away
"Because you're our imōto" Nai replied before starting to wash your hair. Kai took a washcloth and began to clean your body. Soon after they finished cleaning you they washed up. Nai stood you up and wrapped a towel around you. The two wrapped a towel around themselves and helped you out before getting out. They sat you on the king sized bed and went into the closet. They came out fully dressed. Nai sat on the bed with you and began to pull your hair into two pigtails.
" your hair seems naturally curly" he mumbled before placing ribbons in your hair.
You didn't realize Kai left the room till he appeared with a dress [pic]
They quickly changed you before pulling you into a kitchen. Kai handed you a sandwich
"How old are you" you suddenly asked
"8" they replied when you finished the sandwich you felt tired and dozed off on the stool
