Sam x Dean x Reader BSM

"Dean give me back my toy!" You start to throw a tantrum.
"Your one bitchy 5 year old aren't you." Dean snickers while throwing your Barbie doll in the air and catching it again and continuing the pattern.
"Dean be a good big brother and give it back." Sam tries to help but fails.
Both of your brothers are in high school but you haven't even started school yet, and from the way Dean talks about it doesn't seem like you will ever go to school. They don't know who your mom is all the know is dad came home with you one night as a baby. John is gone on a hunting trip so Deans dropping out of school till he comes back to take care of you.
"Don't you have homework to do nerd?" Dean laughs.
"Don't you have the responsibility to take care of (y/n)? So give her her you back." Sam smirks at the comment he just made to his brother then begins his algebra homework. Dean gives you your toy back and turns on the TV and watches a random show that comes on.
"No I wanna watch cartoons!" You yell.
"God damn it (y/n) in a couple of minutes ok!" You can tell Dean is getting frustrated with you but you don't care.
"Cartooooonssssss." You begin to cry, the water works always works.
"Fine you little cry baby cartoons happy now." Dean growls at you.
"Thanks Dean your the best big brother ever." You say sweetly.
"What about me?" Sam asks in a hurt tone.
"Oops." You begin to giggle.
"Your mean (y/n) you know that right?" Sam laughs.
"Uh-huh but you wove me anyway." You smile.
