Futanari.fr is using Hentai-Ultime.net forum.

Maybe you will ask why ? Well, the admin of Futanari.fr et the one of Hentai-Ultime.net is in fact the same person. (hey we speek about me :p ^^) So I thought that usibg the same forum for both websites was better than two differents forums. (and it give less work for me xD)
