Accused sex cult leader Keith Raniere sought virgins as sex slaves and even had his first slave take to hook-up app Tinder to find him new recruits, according to messages revealed in court Wednesday.

Jurors on Raniere’s sex-trafficking trial witnessed the inception of the master-slave group, called DOS, as a woman known only as Camila took a vow of lifetime obedience in a single WhatsApp message on Nov. 27, 2014.

“I vow to do as you say,” the-then 24-year-old wrote — nearly a decade after prosecutors and witnesses say Raniere began having sex with her.

“100 % obedience,” Raniere, now 58, responds. “100 % obedience,” she replies.

He immediately tells her she’s no longer permitted to drink alcohol at all, and must “eat very little.”

The master-slave group grew to nearly 100 members, according to testimony. DOS slaves were groomed to have sex with Raniere, prosecutors say, and followed near-starvation diets in order to appease his sexual preference for thin women.

Some of the members — including “Smallville” actress Allison Mack and co-defendant Lauren Salzman — were even branded with his initials.

FBI special agent Maegan Rees walked jurors through hundreds of WhatsApp messages Wednesday shared between Raniere and Camila , which span the fall of 2014 to February 2016.

In the chats, Raniere demands Camila find them more sex slaves — which he calls successors — and expresses a preference for virgins.

“Find other virgins,” he writes on Dec. 30, 2014. “I like shorter than me, younger is fine.”

Camila even appears to take the search to hook-up app Tinder at one point, and sends Raniere a series of screenshots which were not visible in court.

“My assumption is these are non Espians,” he writes, using the word for students at Nxivm. “Tinder-derived, or the like.”

“Non Espians,” she replies.

It was not immediately clear if they successfully ensnared anyone online.

Jurors were also shown exchanges between the two in which Raniere admits to starting a sexual relationship with Camila when she was a minor.

“I am so proud to have been your husband for 8.75 years,” Raniere wrote her on Aug., 2014. Rees testified that would have made Camila 15 when the relationship started, sometime in the fall of 2005.

Raniere is facing various charges, including sex trafficking, for his role in the group. Camila has not been charged.
