Long hair is something I always enjoyed, ever since I was little. My parents hired a babysitter that we had from the time I was about 6 until I was 10.
She came from an uber-religious family, and so had almost knee-length, stick-straight, thick blonde hair, and I was absolutely enamored with her. She would always let me play with her hair and brush it, and she liked to swish it in my face to mess with me.
I saw her about a year ago, and she looks the same as she did back then, although her hair is just a tiny bit shorter, about to her butt now.
She's most definitely what started my fetish, and the reason why I love blondes in particular!
