Jeffrey Epstein’s Upper East Side townhouse was a creepy lair lined with tell-tale signs of his perversion, including a self-portrait of the multimillionaire and a young girl, and a pair of fake breasts the convicted pedophile played with in the bathtub, a new accuser alleges.

Epstein’s latest accuser, Jennifer Araoz, was taken on an unnerving tour of the $66 million East 71st Street mansion during her visits there beginning in 2001, when she was just 14, she says in papers filed Wednesday in Manhattan Supreme Court.

“Ms. Araoz remembers after the first sexual encounter with Epstein, he showed her a room on the same floor as the massage room that he said was designed to look like his favorite room at the White House, which he called the ‘Blue Room,’ ” the accuser, now 32, says in the filing.

“He then showed her some more artwork, his master bedroom with a large jacuzzi and prosthetic breasts on the wall in a bathroom that he could look at or play with while in the bathtub,” recalled Araoz.

That artwork displayed across the home included “a lot of paintings of nude women on the walls,” the papers said. “He [Epstein] even commented on one painting of a nude woman with small breasts and brunette hair … That painting was right behind the massage table, and he said how much the woman in the picture looked like Ms. Araoz, then 14-years-old.

“He said he liked ‘girls with small breasts’ because they were ‘natural and real.’ ”

On the ground floor, “there was a spiral staircase with a self-portrait of Epstein on the wall with a young girl, who Epstein said he considered like a daughter.”

The identity of that girl is not made clear in the filing.

The opulent sprawl also included a “trophy room” lined with pelts and stuffed with the taxidermied remains of exotic animals.

“The room had marble floors with extremely high ceilings, mahogany wood with deep reds, and was filled with exotic, even endangered animals, including a giraffe and other rare specimens,” the filing said. “There were skins covering parts of the floor with more exotic animals.”

Araoz alleges that, after having been lured from her nearby high school by a female “recruiter,” she was trapped in an approximately year-long cycle of sexual abuse at the hands of Epstein.

As it allegedly began with other underage girls, the contact began with nude massages, and culminated with a forcible rape, claims Araoz.

In 2008, Epstein took a sweetheart plea deal from Florida prosecutors, pleading guilty to two counts of soliciting prostitution — one of which involved a minor — for an 18-month sentence, and dodging federal charges.

But the 66-year-old on Monday was freshly charged in Manhattan federal court with sexually abusing underage girls at his homes in New York and Florida across the early 2000s.
