My best friend's hot sister
I have a crush on my best friend's younger sister. I'm 15 and she's 13 so it's nothing that creepy. But I know how older brothers are. He'd probably cut my balls off with a dull knife if he knew I was always checking out his sister's perky tits and cute butt. But I really really like her and I think she likes me too. I want to ask her out but I'm afraid my friend will hate me for it.
