This was very well written, sexy and sweet. I adored the whole thing, but this particular part:
He loves her for her hair. She wears it down almost every day - sometimes clipped back to frame her face, and sometimes partly pulled into a barrette, but it's never worn so severely as the Cheerios' facelifting ponytails. Puck had never thought he was that into a chick's hair before, but when Rachel wears hers in two low pigtails, he's almost overcome by a Neolithic urge to grab them like handlebars and ride Rachel Berry like a dirt bike.

I love so damn much. I cracked up!

Terrific!
