From a very young age, I wanna say 4 or 5.
I had a family friend who was my babysitter with thick, silky, stick-straight blonde hair that went right about to her ass. Sometimes if I was being extra rowdy or was in a playful mood, she would have me lay down, tickle me, & swish her hair in my face. I would mess with her by tugging on it and running away, and every now and then she'd sit down and let me play with it or help her brush it.
We still keep in touch every so often, and she's just as hot now as she was then. Her hair is only shoulder-length now but she's expressed wanting to grow it out again. I hope she does ????
