Can Anybody Tell Me Where This .GIF Is From??

Hi. I'm new here and this is my first post. I'm not sure if this is in the right area, so if it's not, mods feel free to move it where it belongs.

I stumbled upon this very hot .gif:

and I MUST find the scene that it's from. If anybody knows I will forever be in your debt. Or if someone can tell me who the one girl is (the one who's face you can see) that might help me ID the scene too. Any info would be greatly appreciated. Thanks.
