An alleged rape victim of Soros Fund manager Howard Rubin says she was tricked into agreeing to a settlement offer, only for Rubin to later demand she clear his name after they already hashed out the deal, according to new court papers.

The woman — who claims she was brutalized at Rubin’s sex dungeon during an S&M session where he repeatedly ignored their “pineapples” safe word — says the financier offered her a settlement deal Sept. 5, according to court papers filed Friday in Manhattan Supreme Court.

On Oct. 3, the woman formally accepted the settlement amount, which was redacted in court papers, but then heard back from Rubin’s lawyers: “We insist that your client sign a statement exonerating Mr. Rubin,” the court papers claim.

Her lawyers said this was effectively rescinding the offer in a move of “pure gamesmanship” and the judge should make Rubin honor the initial offer and sanction Rubin and his legal team.

“The case for all intents and purposes was done, and [the victim] could finally focus on her future,” her lawyer, Kevin Landau, said in the court documents.

“Counsel for Defendant completely misrepresented the terms of the settlement agreement they had offered to attempt to coerce a statement exonerating his client of rape, which is unethical and in violation of the Rules of Professional Conduct,” Landau wrote.

Rubin’s lawyer, Edward McDonald, said Landau is simply trying to negotiate a higher settlement amount, highlighting one of Landau’s emails.

“You made an offer of [redacted dollar amount] with no conditions aside from dismissal of claims. We accepted that offer,” Landau wrote to McDonald Oct. 4. “Should you wish to engage in a separate agreement, inclusive of your new condition, our client is firm at [redacted number].”

“She has agreed to include our condition, that condition being to exonerate him of false and malicious charges, and now [Landau is] clearly negotiating another number,” McDonald told The Post.

“What they are bickering over is the [settlement] number,” McDonald added.

Landau told The Post Rubin’s camp’s move, “is akin to purchasing a vehicle for a firm purchase price and then when the time comes to turn over the keys, the seller balks and says he’s going to take the engine out unless you include the family dog.

“It’s a contrived approach, which we assert is prohibited by well-grounded case law.”

The woman claimed in her $7 million lawsuit from January 2018 that she went on a date with the married Rubin at the Russian Tea Room. A mutual friend, who set up the dinner and drinks, said she would get $2,000 for the date and wouldn’t have to sleep with Rubin, according to her lawsuit.

But he allegedly plied her with drinks, made her sign a non-disclosure agreement and brought her back to his luxury Metropolitan Tower penthouse, where he beat and raped her, the suit claimed.

Before the S&M session, where he tied her hands, he told her to use the safe word “pineapples,” which he ignored when she cried out trying to get him to relent, the suit alleged. Rubin, whose high-risk investments under billionaire George Soros were featured in the best-selling books “Liar’s Poker” and “The Big Short,” has denied the woman’s claims.

Last month, another woman alleged in a lawsuit she was sexually abused by Rubin and another woman at his apartment, and that Rubin later threatened to discredit her as a prostitute if she brought claims against him. Rubin also denied those allegations.

Three other women brought similar claims of sexual abuse and rape against Rubin in a Brooklyn federal lawsuit in 2017. That case is still pending.
