Her attorneys did not respond to requests for comment.

Powers would tell the women she recruited that Rubin would pay $2,000 for a night, or up to $5,000 if Rubin had a particularly good time.

Many of them came from out of state.

That room in the apartment, the so-called sex dungeon, was soundproofed, according to prosecutors.

The room was painted red, and Ruben had it filled with ropes, whips, and sex toys.

While some of these women knew to expect aggressive sex, like BDSM, victims say Rubin took it much further than that, and that the encounter is often tipped into torture.

Rubin did give the women a safe word, but several said he ignored it.

Multiple women accused Rubin of rape.

The women were told to sign an NDA.

And if they broke it, they would have to pay Rubin $500,000.

And then what would happen after all of this was over?

Howard Rubin's secret would eventually get exposed.

How that happened is next.

Howard Rubin and Jennifer Powers' alleged sex trafficking enterprise began to fall apart in 2016.

It started with a group of women who were at Ruben's apartment at the same time.

According to court records, Ruben himself wasn't there, but a fight broke out between two women.

After that day, the women started comparing stories.

This is what would ultimately form the basis of two civil cases and later a criminal investigation.

What did Rubin and Powers do when they found out that these women were coming together to sue them?

Rubin was found liable and ordered to pay $3.8 million in total to six women as part of the first case.
