A man who's accused of leading a sex cult near the Hudson Valley is now facing more charges.

On Wednesday, Nxivm leader Keith Raniere was charged with child exploitation and possession of child pornography. He's accused of having sex with two underage girls and producing child porn, according to unsealed court documents obtained by the New York Post.

One of the girls, who was 15 when Raniere allegedly had sex with her, later became his first 'slave' in his alleged sex cult, according to court documents. Raniere’s co-defendants, “Smallville” actress Allison Mack,  Clare Bronfman, Lauren Salzman and Kathy Russel are accused of knowing Raniere had sex with an underage woman and even helped.

Raniere’s attorney tells the New York Post the new charges "serve only to taint the jury pool."

Raniere, 58, is accused of leading an Albany-area slave sex cult within Nxvim, where he allegedly forced women to have sex with him and branded them. He was previously charged with sex trafficking, forced labor, wire fraud conspiracy, human trafficking and more.

Nexium co-founder Nancy Salzman pleaded guilty on Wednesday to one count of racketeering conspiracy. Former "Smallville" actress Allison Mack is out on five-million-dollars bond and is charged with sex trafficking for allegedly recruiting and grooming women for Raniere.
