You're a lucky guy Jim... that length is great... and gorgeous color and thickness.
Since she's aware and agreeable to your fetish, you should ask her to teach you to curl her hair...
I see by the first pic that she uses a curling iron of some sort...
I can tell you from personal experience that if you get into the habit of "spoiling her" by doing the curling work FOR her, your sex life will go through the roof. And the first time she says out loud in mixed company that YOU curled her hair, at first it may feel awkward but watch the face of other women... I'll bet they are interested.
And guys will actually be jealous... but too shy or stupid to say something to their own...
Say hi sometime... I'll show you some of my handiwork in these regards... :-)
