Rei and Kaoru from Oniisama e by Ikeda Riyoko

This page contains descriptions and a few teaser scans of yuri scenes from various manga and doujinshi; it also contains various yuri- and Maria-sama ga Miteru-related files, which can be found here. Feel free to pimp the server as much as you'd like. :)

Most of the descriptions were originally written for the daily_yuri community on livejournal, but I wanted to share them with a broader audience.

A note on the scans: I found most of these scans using the Japanese peer-to-peer programs Winny and Share. It should go without saying that they're free-use, although I don't believe in "ownership" of scans anyway. It would be nice if you could mention the title and mangaka when posting the scans other places, though, so that people know what they're from. :)
I've included the ISBNs for all of the manga (save the ones that are only available printed in magazines); I believe none of them are out of print yet, so you should be able to get them through most Japanese bookstores.
At this time, none of the scans posted here will contain adult content, even if they come from H-manga.
One last warning: these descriptions contain spoilers. Read at your own risk.
