How many Family of Debauchery volumes are there?

[Samael]

I was wondering if there is any more volumes of the Family of Debauchery series besides just Vol 1 and 2. I hope there are more or more are in development. I'd eventually like to see a guy seduced by the "sisters."

There are only the two volumes, which are based on a manga (Japanese title: 背徳の少女; ISBN 479010544X). The author (橘 敦司) has also published two more volumes, 背徳の処女 (ISBN 479010768X) and 痴辱の艶女 (ISBN 4790109046), which are presumably related.

Any idea where I can buy those volumes? Actually before I do go looking does any of them involve a guy being seduced by the main characters from the anime, whom I assume are the main characters in the manga too?

They seem to be out of print; I got my information from Amazon.co.jp. I recommend asking the question in Anime on DVD's Retail Forum, where it is possible to discuss retailers other than AnimeNation (I'd be generally interested in the answer as well, as I am also looking for an out of print manga series, and hope to pick up the first volume without paying a ridiculous amount of money). As for content, I have not read them, nor do I possess them. -_-;
