A former model claims she was raped by Jeffrey Epstein in New York more than 25 years ago — and is wracked with guilt at seeing so many other alleged victims come forward in the decades that followed.

Speaking about the alleged sex attack for the first time, Amy McClure told The Sun that the late pedophile raped her on the floor after she agreed to massage him at his Manhattan mansion in 1993.

She recalled how he made her feel “embarrassed and ashamed and stupid” — and that he got “irritated, almost angry” when she told him she was 21.

“He said something like, ‘You’re too, you’re too old. You’re getting too old for this. What are you doing?’” McClure told The Sun, calling it “crushing” and also alarming when he threatened her at the end.

“He said, ‘If you tell anybody anything I’ll crush whatever career you might have,’ or something like that. He was just so mean so quickly.

“It literally went from awkward to mean to rape so fast,” she told the UK paper.

The alleged attack would be one of the oldest allegations against Epstein, who died in August after being found hanged in his Manhattan lockup.

McLure, originally from Oklahoma, says she is wracked with guilt wondering if she could have stopped his decades-long reign of terror if she had spoken up at the time.

“I didn’t say anything to anyone at the time because I felt like it would come across and look like it was my fault,” said McClure, who has a daughter with former Calvin Klein CEO Arnold Simon.

“I felt nobody would believe me. I blamed myself for a lot of it.

“And I didn’t know what anyone could do anyway, these people were from a different world — they were rich, untouchable. Although I didn’t know quite how untouchable back then.”

McClure told the paper she is tormented that Epstein “effectively got away with it really all the way until the end.”

“I look back on it and I just think, ‘Oh my gosh, how many other people did he crush their spirits in that way?’

“And it’s not just a physical act of rape. You can also rape someone’s dreams and their soul, their future forever.

“And there’s not any way to pay any of these women back for that.”

McClure says she will cooperate with the district attorney’s office in case she can help the investigation against accused accomplices.

She said Prince Andrew’s recent “car crash” of an interview about his ties to Epstein made her “angry” — and that Ghislaine Maxwell, the accused madam she never met, sounds like a “Disney villain.”

“He’s a sick, sick monster of a man, but if it’s true that she found these young girls for him and set it all up, she’s even worse,” she told The Sun.

“She needs to come forward and explain herself to all the victims,” she said of other women’s allegations, which she likened to dropping “these young girls to Epstein like baby mice to a snake.”

McClure’s lawyer, Spencer Kuvin, also said he is determining whether a lawsuit can still be filed against Epstein’s estate.
