I'm gonna finish the Rui Nanase at a later date so I can post what I have of the OPPW series. There's a bunch that I need, so if anyone can fill the gaps, that'd be great. A big one I'm looking for is OPPW-015 starring Mirai Futaba. If you got 'em, post 'em!
There are active torrents for most of these, if the gofile link is dead, try OneJav. As always, Enjoy!
