Looking for a doujin I read years ago about the princess of I think a Mediterranean island, who was lonely, horny, and getting past the desired age to produce an heir. She had a large public wishlist of hentai on an Amazon-style shopping site, and through this her maid was able to determine her taste in men, and got her a man. They had sex on her huge ritzy canopied bed. At the end it was revealed that her wishlist was public and that she was infamously known as “the hentai princess” or something like that.
I've been looking for this for years!
