My girlfriend does exactly what you described, with my nipples. And it drives me insane.

She then let's me stuff her hair into my wet pussy. And when she pulls it out, she'll lick all my cum of her hair.

I'm the one that wears the strap-on in our relationship. And when I'm ramming her moist pussy doggy style, my hands are always in her hair - gathering, stroking, holding, pulling. She loves it.

Girsl enjoy long hair too.
