Actually, I found her full name, Naoko Ariyoshi.
Some solo pics on a Japanese blog:

There are several videos of her on this pay site:

If you put her name in Japanese (her name in Japanese is the first five characters in the blue topic bar above her first picture on the second link I posted - you can copy and paste), or English, into one of the search engines, you can probably find more. There are a few free downloads of her, but the sites are banned on Peachy, so I can't post the links.
