Slytherin next

You let the Slytherin and Gryffindor continue to mock Ravenclaw as they moved a couple more places up the queue, waiting for a second chance to strike.

As soon as Slytherin is in mid joke about Ravenclaw's underwear you blow up the wind once again, this time focusing it on Slytherin's far shorter skirt, and revealing far more.

Unlike Ravenclaw's panties, Slytherin was wearing an almost see thru thong her bare arse cheeks on display to everyone behind her.

She lets out a little scream and copies Ravenclaw, trying to smooth her skirt down and cover her embarrassment as several more pairs of eyes begin to focus on the little group.
