Yeah, The Story of O has appeared on legit presses and bookshops here too (in Sweden), without juicy cover art though, just very dark lilac. I imagine the writer would have approved of that. A few years ago it was even broadcast as radio theatre on the public waves network. I could cite a few local writers here who have explicitly written about bondage and sexual humiliation as a theme - in ways that really make you think they have to have personal experience -and who got good reviews, not translated into English though.
