A kinky money manager allegedly pulled off a disturbing scheme to rape Playboy Playmates in his penthouse dungeon with the help of three female “fixers” — including a former Brooklyn prosecutor, according to court papers.

Yifat Schnur, who worked as an assistant district attorney from 2005 to 2010, tried to cover up Howard Rubin’s sick acts by drafting up non-disclosure agreements the three models — Hillary Lawson, Kristina Hallman and Stephanie Caldwell — were forced to sign before they met Rubin, according to the womens’ lawsuit.

The trio of women filed a blistering lawsuit Thursday against Schnur, Rubin and his other “fixers,” Jennifer Powers and Stephanie Shon, claiming they were raped and seriously injured by Rubin in his BDSM-themed dungeon located in a 76th floor penthouse at the Metropolitan Tower.

The suit also accuses Schnur of obstructing justice and “intimidating witnesses” by interfering with a related criminal case involving Hallman, who was charged with slugging her model pal at the penthouse last year.

Rubin and his crew allegedly agreed to pay for Hallman’s criminal defense lawyer, Jeremy Saland, “so long as Hallman agreed not to mention in the criminal trial anything about Rubin or the other members of the enterprise,” the suit said.

But then they made an $80,000 offer to Hallman to ditch Saland, sign a confidentiality agreement and retain Schnur instead, according to court papers.

“Schnur agreed to represent Hallman, despite obvious conflicts of interest, and violations of her duties as an attorney,” the suit, filed by John Balestriere, said.

Powers also instructed Hallman to “lie to the police” by telling them the penthouse either belonged to Hallman or Zoe Cacciola, the woman she is accused of punching, “in an effort to keep Rubin and the rest of the enterprise out of the news,” the suit alleged.

Hallman’s case is still pending. She kept Saland as her attorney — even though Rubin and his crew allegedly threatened to stop footing Saland’s legal bills.

In a statement, Saland said he confronted Schnur about her unethical conduct and repeatedly asked her not to contact Hallman.

“Defendant Schnur, for the benefit of and to protect Mr. Rubin, contacted my client in an attempt to silence her, pay her monies and have her sign an agreement,” he said. “Defendant Schnur could have succeeded in taking advantage of a vulnerable person.”

Powers, a former Hawaiian Tropics model, dated Rubin 10 to 12 years ago when he was in his “brunette phase” but she went on to marry one of his friends, the filing said.

She and Shon allegedly lured the models to New York by sending them messages on social media and promising them as much as $5,000 apiece to “meet and spend time with Rubin.”

Schnur now works as a defense lawyer based in Edison, New Jersey and graduated from Stern College for Women, an all-women’s branch of Yeshiva University.

“The allegations against Mr. Rubin and his attorney, Ms. Schnur, contained in the complaint are fabricated and 100 percent untrue,” said a spokesman for Schnur. “The plaintiffs’ baseless complaint is a web of lies intended to extort Mr. Rubin. All appropriate law enforcement agencies, including the FBI, have been contacted.”

A woman at Powers’ E. 87th St. address said she wasn’t home.

Rubin — who most recently worked as a portfolio manager at a George Soros-founded investment fund — didn’t immediately return messages.

Shon couldn’t be reached.
