The images come from a (now closed) blog called Dorei Fujin (奴隷夫人), also known as Papermania (because the blog address was http://papermania.blog65.fc2.com). Dunno the artist name, but as far as I remember, she's a female.
Note that I don't think there is a single picture in this gallery that haven't already been uploaded on EH: https://e-hentai.org/tag/papermania
