What is the name of this anime with nekomimi?

I have been wondering for a long time which anime this is from.




This isn't from an anime. It's original art by [this Pixiv
user](http://www.pixiv.net/member.php?id=970058) (warning, may be a bit NSFW)
for her [FC2 blog](http://naomi703703703.blog112.fc2.com/) (also maybe not
safe for work).

The characters in the image are:

  * Hayami Shizuku (white hair, green eyes)
  * Hutaba Akane (blonde hair, red eyes)
  * Hutaba Aoi (blonde hair, blue eyes)
  * Neko (brown hair)
