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 (warning, may be a bit NSFW) for her FC2 blog (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)
