A former follower of a self-help guru is telling a jury how the leader created a sorority of sex slaves under his command.

The testimony by Lauren Salzman came Friday at the New York City trial of Keith Raniere. Raniere pleaded not guilty to charges he formed the secret society within an upstate New York group called NXIVM that allegedly branded devotees with his initials.

Salzman testified that she and other women, including TV actress Allison Mack, were labeled "slaves" and Raniere was their "master." She said when he met with them, they were required to take off all their clothes and sit at his feet.

The 42-year-old Salzman is testifying after pleading guilty to charges she abused lower-ranking slaves. Mack has also pleaded guilty.
