Holly's hot sister

The unatainable goddess that you want to fuck, and every guy and most girls in your school/ area wants to fuck.

Her ledgend started when she was still in middle school and her older sister was in high school. A select few of her older sisters friends met her. Before she even got into high school she was well known. Of course her overprotective older sister prevents much from happening. The hhs her self usually donsen't try to act sexy but is a quirky indie chick type instead, but they all know she's sexy.

Guy 1: Dude look at that girl...
Guy 2: Don't even try she's a Holly's hot sister. You used to date her older sister too.
Guy 1: Dammit!

Big sister

A big sister will mostly likely treat u like trash but deep down inside they love you. Sometimes when a baby sibling gets hurt they will most likely care for them like mothers but as a sibling.

*baby brother gets yelled at for spitting at his brother* then big sister comes in. *big sister holds him and hugs him for comfort*
