This is so freaking hot.

It would be even hotter if:

1. The blonde had longer hair.

2. As part of the dance routine (early on), she pulls out the hairtie and releases her hair (making a bit of a spectacle as she does so, for the benefit of all the viewers), and let's it sway and bounce naturally too as they continue dancing.

3. They share a sensuous kiss at the end, with their hands in each other's hair.

Carrying the second point further, imagine if lolahontas had her hair in a classy, elegant, sexy updo at the start of the dance. And at exactly the same time that Blondie releases her ponytail from its confines, lolahontas' updo gets...err...undone...slowly from all the movement and tumbles down like a waterfall in glorious freedom.

Aww man...this fetish...
