She may have a new house and a new name, but Amy Fisher still has plenty of “Long Island Lolita” in her — even 25 years after shooting her married lover’s wife in the face.

Just days after she insisted someone was posing as her to perform online peep shows for cash, The Post found Fisher, 42, titillating porn fans by pleasuring herself with a pair of sex toys in front of a webcam in her family’s Long Island home.

“Come on, guys, talk dirty to me. Tell me what you want me to do,” Fisher said while trying to coax big bucks out of her viewers ahead of her hardcore solo performance in the nude.

“I’m all alone here, you guys need to tell me what to do,” she purred.

The divorced mother of three was performing in a bedroom with the same tan-and-white decor — complete with chair-rail molding and mirrored closet doors — seen in photos of the Bohemia home into which she moved earlier this month.

Fisher lives there with her mother, 8-year-old son and 12-year-old daughter.

She attracted a crowd of between three and nine viewers, imploring them, “Be generous with your tips, guys” while griping that she only gets 30 percent of the total take.

During a $10-a-minute “private chat” with The Post, Fisher — whose profile identifies her as “AmyFisher” — answered questions about her work.

“This is what I do. This is a sex show. You can stay here as long as you want, you’re paying. I love it,” she gushed.

Fisher — who wore the same gold hoop earrings as when The Post recently photographed her outside her Suffolk County house — refused to say if her notoriety drew viewers to her act, which she offers weekdays from 9 a.m. to noon.

But she’s been tagged as a “celebrity” on the site nine times.

Last week, The Post exclusively revealed that Fisher had fled back to Long Island after several years in Florida because her children were being “ostracized’’ over her “Lolita” past.

In an interview for that report, Fisher falsely denied any involvement with the “live sex” porn site.

She again denied it online, when The Post asked if she was the former teen temptress whose infamous affair with auto body shop owner Joey Buttafuoco led her to shoot and wound his wife, Mary Jo, with a .25-caliber pistol in 1992, sending her to prison for six years.

“I just use the name,” Fisher claimed during the private chat.

But in addition to the damning evidence that The Post uncovered to the contrary, Fisher confessed her X-rated online antics to an independent TV producer who contacted her in February while working on a documentary about Mary Jo’s recovery.

“We had about a 15-minute conversation. She even mentioned her mom, that her mom is there with the kids and, ‘This is what I have to do to make money,’ ” Lori Rothschild Ansaldi, of Tent City Productions, told The Post.

In her online profile, Fisher describes herself as a “horny housewife alone during the day” and falsely claims to be 33 and a “Latina,” even though she’s of mixed Jewish and Italian-American heritage.

She lists several “kinky attributes” and says she likes “sweet sexy men.”

Fisher refused to comment after her Friday shift, but her loyal, long-suffering mom defended her daughter’s tawdry career choice.

“She has a right to her life. I have a right to my life,” Roseann Fisher said outside their four-bedroom ranch home.

Amy’s ex-husband, Lou Bellera, who still lives in Florida with their eldest son, 16, told The Post, “I certainly don’t approve of what she’s doing, but we’re divorced two years now.

“I can’t force her not to do it,” he lamented.

Bellera, a former NYPD cop, said he’s suggested to his ex-wife that she “get a smaller home, get a normal job.

“She said, ‘No, I’m spoiled and there’s too much money to be made,’ ” he said.

Fisher’s neighbors were shocked to learn about her behind-the-shades shenanigans.

“She does porn in the home there? Wow. I can’t believe it,” said one woman as she walked by.

Another woman who lives nearby fumed: “We don’t need that here. I have teenage children.”
