Jeffrey Epstein had an insatiable sexual appetite that included threesomes with “strap-on” dildos and a required three orgasms a day, according to court documents unsealed Friday.

The convicted pedophile would allegedly have his butler clean up after him once he was finished with his victims.

“I would find things like a dildo,” said John Alessi in a 2016 deposition unveiled in Friday’s document dump, which was related to a defamation suit filed against Epstein’s alleged madam, Ghislaine Maxwell.

Alessi noted how Epstein’s sex toy of choice was “called a double.

“I find these things, put my gloves on, [take] it out and rinse it and put it in Ms. Maxwell’s closet,” he said, speaking to the lawyer for Epstein accuser Virginia Giuffre, who filed the defamation suit.

Maxwell, a British socialite, helped the accused serial rapist recruit and groom underage girls to abuse, according to the court papers.

Giuffre was allegedly recruited at the age of 16 and abused for years.

Her former boyfriend testified how she told him about alleged threesomes she had with Maxwell and Epstein — and how the pair would both use “strap-ons and stuff like that.’

“I remember her talking about, like, how they would always be using … stuff like that,” said Tony Figueroa, who was engaged to Giuffre at one point.

“I [was] obviously not happy about it,” he added.

Epstein told another accuser, Joanna Sjoberg, that he needed to have “three orgasms a day.

“It was biological, like eating,” she said he told her.

One of his alleged victims, who was unnamed, also claimed that Epstein, 66, had a “deformed’’ penis.

It was “egg-shaped,’’ the accuser said.

Maxwell and Epstein made Giuffre sit back and watch as they engaged “in illegal sexual acts with dozens of underage girls,” the documents allege.

The 2,000 pages of documents were unsealed in Manhattan federal court and related to Giuffre’s suit, which was filed in 2015 and eventually settled out of court. The Post was one of more than 30 media organizations that filed lawsuits to get the documents released.

The papers include testimony from numerous people close to Epstein, including Maxwell — who skirted questions about whether the wealthy financier sexually abused minors.

“I can’t testify to that because I have no idea what you are talking about,” she told Giuffre’s legal team.

Depositions from others, however, offered an alleged glimpse into Epstein’s sick and twisted life — along with photos that were unsealed Friday, also.

One image, which was collected during the execution of a search warrant on Epstein’s Palm Beach estate in 2005, showed “the bare bottom of a girl who appears to be pre-pubescent,” according to the court papers.

Another picture was of an Amazon receipt listing some sadomasochistic books that the wealthy financier allegedly purchased under his own name. The titles were “SM 101: A Realistic Introduction,” “SlaveCraft: Roadmaps for Erotic Servitude,” and “Training with Miss Abernathy: A Workbook for Erotic Slaves and Their Owners.”

There also were photos of phone messages left for Epstein at his Palm Beach, Fla., mansion.

“I have a female for him,’’ reads one of the messages.

Another says, “He just did a good one – 18 years – (She spoke to me & said “I love Jeffrey”).

A search warrant uncovered bars of soap shaped like genitalia, too, the papers say.

A staffer for one of Epstein’s billionaire buddies once tearfully testified that Maxwell brought a 15-year-old Swedish girl to Epstein’s mansion and forced her to have sex with him.

The teen was distressed and “sat in the stool exactly the way the girls that I mentioned to you sat at Jeffrey’s house, with no expression and with their head down,’’ recalled Rinaldo Rizzo — “house manager’’ for hedgefunder Glenn Dubin and wife Eva Dubin, who is Epstein’s former girlfriend.

Rizzo said the girl told him she had just been “on an island’’ didn’t know how she got to Dubin’s house — and that Maxwell swiped her passport to hold her hostage.

“She was shaking uncontrollably,” Rizzo testified, describing the teen.

Another victim told police that Epstein claimed to have purchased an assistant from her family in Yugoslavia so she could he his sex slave.

One accuser said Epstein told her friend that he’d taken a girl’s virginity.

“You see that girl over there laying by the pool?” Epstein allegedly asked her friend, according to the documents.

She was 19, the woman said.

“He said, ‘I just took her virginity.’ And my friend … was mortified.’’

Multiple people have claimed that Maxwell helped Epstein groom underage girls for erotic massages and various sex acts, according to authorities and the court documents.

Maxwell “assisted in internationally trafficking” young girls for Epstein and his pedophile buddies “for sexual purposes,” according to the court docs.

Giuffre claimed she also was ordered to sleep with a number of powerful men — including Prince Andrew, former US Sen. George Mitchell, former Gov. of New Mexico Bill Richardson, Dubin and late longtime MIT professor Marvin Minsky. Several of the gentleman have been identified in the past as being Epstein’s alleged cohorts.

Epstein, 66, was busted last month on sex-trafficking charges in Manhattan and is facing up to 45 years in prison if convicted.

The accused pervert had been facing charges in Florida in 2008 of soliciting an underage girl for sex, but the federal investigation was thrown out — leaving Epstein with a wrist-slap sentence that landed him behind bars for just 13 months.

Prince Andrew denies the allegations, while a spokesperson for Dubin said “Glenn and Eva Dubin are outraged by the allegations in the unsealed court records, which are demonstrably false and defamatory.”

Brunel didn’t immediately return request for comment on Friday, and Richardson could not be reached. Sen. Mitchell provided a statement, saying “the allegation contained in the released documents is false.”

Giuffre says in the documents that President Trump, a onetime Epstein pal, “didn’t partake in any sex with any of us.’’
