My investor husband pushed me into sex swaps for biz deals

Christina Kelly says her investment-banker husband made her go the extra mile to help him land a client — pushing her into a partner-swap with the business honcho and his wild girlfriend.
The mom of two revealed details of the kinky alleged hookup — and every drug binge, extramarital pool fling and sex encounter in between — in salacious Manhattan court papers targeting her husband, Jefferies & Co. wunderkind Sage Kelly.
And now, she and her reputed real-life “Wolf of Wall Street’’ hubby are “the talk of the town,’’ a Wall Street source said.
“All the top Wall Street and hedge-fund guys are talking about it. They are all ­e-mailing it to each other,’’ the source said of Christina’s 26-page affidavit.
“It is a complete bombshell and a shocking and wild read. It’s just irresistible.
“The most astonishing thing is that the complaint says Ben Lorello, who is head of investment banking at Jefferies — a top health-care banker and very powerful guy on Wall Street — was part of a cadre of guys who do cocaine all of the time,” the source noted.
Another source added, “We know what this is all about — this is revenge.”
Christina Kelly alleges in nearly every page that her $7-million-a-year hubby is nothing but a coke- and Ecstasy-loving, booze-swilling, abusive spouse and dad who lives for seamy sex romps.
Christina, 39, said her husband, 42, was trying to woo Aegerion Pharmaceuticals honcho Marc Beer the night she wound up having sex with Beer — and “sexual contact’’ with his prancing, big-breasted girlfriend, according to the papers.
The former Ralph Lauren event planner said the sex jaunt occurred in a hotel room at the Ritz-Carlton in Boston in 2012 after a booze- and cocaine-fueled evening.
“Soon, Sage and I were having sex with each other on one bed, and Marc and his girlfriend were having sex on the other bed,’’ Christina says in her affidavit.

We know what this is all about — this is revenge.

“Then, Marc said, ‘Let’s switch,’ ” she claims in the papers. “Marc suggested that his girlfriend and I have sex with each other.
“Mindful of [Sage’s] goal of securing business from Marc, I felt responsible not to disappoint Marc. So, his girlfriend and I had sexual contact for a few minutes, while Marc and Sage watched.
“Then, Marc’s girlfriend joined Sage on our bed, and Sage and she started to have sexual relations.
“Then, I joined Marc on his bed, and he and I engaged in sexual relations,’’ Christina said in the sworn affidavit.
“Following that evening, Marc Beer has been an important client of Sage and, presumably, a substantial reason for Sage’s enormously successful career at his current investment bank, Jefferies and Company Inc.,’’ she said.
Christina, a graduate of the tony Horace Mann school in Riverdale, said her husband of 12 years routinely pestered her into engaging in threesomes.
She also alleged his sexual conquests outside their marriage included a romp with the wife of co-worker Dung Nguyen in the swimming pool at the Kellys’ family vacation home in Sag Harbor, LI.
A few months after Boston, during a visit from Nguyen and his wife, “I noticed Sage sitting on the stairs in the shallow end of the pool,’’ Christina said in the court papers.
“I heard Jessica moaning, ‘Oh, Sage.’ ’’
Christina and Sage Kelly have two daughters, ages 10 and 6.
Christina noted that at least one of their kids’ bedrooms overlooked the pool.

‘I felt responsible not to disappoint Marc. So, his girlfriend and I had sexual contact for a few minutes.’

She also said Nguyen and a slew of other business associates of her husband did drugs with Sage — and she included names in her affidavit.
The list also included Myriad Solutions CFO Mark Hosny, UBS’s Bjorn Koch, Sage’s boss Ben Lorello, and the head of Seattle Genetics, Clay Siegall, the filing claims.
Beer said through a spokeswoman, “Ms. Kelly’s accusations as to me are categorically false and baseless. I do not use ­cocaine or any other illegal substance.
“All of the allegations which Ms. Kelly has made regarding me and my girlfriend are ridiculous, baseless and grossly irresponsible.”
Lorello said through a Jefferies rep that he also “categorically denies all the allegations regarding him raised by Ms. Kelly in her matrimonial case.”
Nguyen said through the rep that he, too, “categorically denied the allegations made about him by Ms. Kelly.”
Siegall said in a statement, “Ms. Kelly’s accusations as to me are baseless and absurd. I have never used cocaine in my life. The allegations as to me are completely and unequivocally false.”
Messages to Hosny and Koch weren’t ­returned. Sage Kelly hung up on a Post ­reporter Tuesday. He has said in previous court filings that his wife’s claims are an “outrageous lie.”
“While [she] and I used recreational drugs on occasion at certain social events in the past, the ‘Wolf of Wall Street’ tale she tells this court is a work of fiction,” he said in an August filing.
The tall, handsome Boston College grad won temporary custody of their kids after he secretly installed cameras in the couple’s Fifth Avenue apartment that caught Christina drinking and snorting coke, ­according to her suit.
Besides her admitted cocaine use, the ­petite blonde drunkenly drove her Range Rover into a utility pole in the Hamptons in 2010 with her two kids in the car, Sage says in court papers. She is currently on a conditional probation, he adds.
In a bid to get the girls back, Christina filed a countersuit claiming it’s Sage who is the real danger to the kids.
She said he once slapped one of the little girls across the face for saying she was afraid she might pee herself — and routinely calls the kids “f–k­ing retard’’ and “f–k­ing idiot.’’
“Mommy, can you please tell Daddy to stop calling me a f–k­ing retard?’’ one of the little girls asked her, the filing says.
And Christina said one of her husband’s pals also “inadvertently left a bag of cocaine on a pool table’’ at the family’s Sag Harbor home — and one of the kids stuck her finger in it. Christina says she stopped the child before she could ingest it.
Christina said Sage was so into drugs that he once hosted “Mushroom Day” in the Hamptons where “he continually ­ingested [psychedelic] mushrooms throughout the day . . . while the children were present.”
He also urinated and defecated on himself in bed, she said in the papers.
