From the thumbnail I thought that was Yomogi's girl. But that's probably more an accidental resemblance.

For what it's worth, the original page the image was on is: http://www.pixiv.net/member_illust.php?mode=medium&illust_id=779007 . I can't read Japanese, so it doesn't help me much.

The description says "Cats are always naked so it's ok", the title says "I love catgirls", the tags are just "breast", "cat", and "R-18".
