The best known book is of course Les Editions Ostra by Alexandre Dupouy. You can buy it directly from his site, I can also recommend browsing the web since the book is offered by various sellers these days.
There is also an ebook I don’t recommend, Paris Sex Underground with 60 photos. I downloaded it and felt almost ashamed. The quality of the photos is really poor, you can find more when browsing the web (and of course on my site and totally free 😉
