Yum. Excellent smut, with a good use of magic to achieve what can't (unfortunately) be safely accomplished by us mere mortals.

I'm curious - the parts of Ginny (in this case, her hair) that blew over the top of the car - would those be visible to Muggles, since it's beyond the physical scope of the car? Or still invisible? That was a really cool concept, btw, to have the car still look like it was top-up and tinted. Very sexy to have Ginny baring herself - but only for Draco.
