ARON Fink thought he had struck the jackpot when he started speaking to a woman online.

For one thing, she was single. For another, they appeared to have mutual interests.

And most importantly, she had two underage daughters aged 8 and 10, and was willing to let them take part in his sick fantasy.

“Hello kinky perverted guy from South Florida into incest, family … and lots more,” the 44-year-old man from Florida wrote, using the screenname ‘KinkyDaddy4y’.

“I have been looking for a mom who was raised in an incest family and wants to continue the beautiful world of incest with their kids.

“I have wanted an incest family since I was younger. Nothing turns me on more than family incest. So special and hot!”

He sent the family naked photos of himself, and hoped he could have a child with the woman so that they could sexually abuse the infant together, reported The Sun Sentinel.

For weeks on end, he intricately discussed his fantasies about having sex with the mother and her girls.

Fink eventually arranged to meet the family at a Steak N’ Shake in Royal Palm Beach, where he thought he would finally be able to begin bringing his disturbing fantasies to life.

He never would have guessed he’d been talking to undercover FBI officers that whole time.

When Fink arrived at the restaurant in August, he was immediately arrested. In October, he pleaded guilty to a federal charge of attempting to entice a minor to engage in sexual activity through the use of a mobile phone and computer.

He made no attempt to deny his behaviour, expressing relief that he had been caught, so he couldn’t act on his desires.

“I have no excuses... I do have a problem,” he told the judge.

No evidence was found that Fink had ever abused a child, nor did he have a criminal record.

Following his arrest, Fink suffered severe beatings at Palm Beach County jail. According to his lawyer, his jaw was fructured in multiple places, and his mouth was wired shut for five months. He did not reveal who had assaulted him.

Fink is currently in solitary confinement for his own protection. He will spend the next 10 years in prison, followed by 20 years on probation.

He will be registered as a sex offender for the rest of his life.
