Michael Spencer, of Skegness, Lincolnshire, made contact with the officer, based in Virginia, USA, and boasted about his exploits.
He then made a five-year-old perform a sex act on him.
So, just to be clear, the FBI agent was on Skype with Spencer; the girl was physically with Spencer in Skegness.
At Lincoln Crown Court, the 46-year-old admitted sexual offences and was jailed for 12 years and nine months.
Spencer contacted the undercover officer through an online chatroom that specialised in the sexual exploitation of children.

for sexual offences involving children
The conversation and the sexual abuse of the girl were recorded before the FBI traced him to an address in Skegness and informed Lincolnshire police.
Days later Spencer was arrested and officers seized computer and mobile phone equipment which showed he had been distributing indecent photographs of children.
Stephen Kemp, prosecuting, told the court Spencer had also been having regular sex with a 15-year-old girl which only ended when she became pregnant.
The girl, who had mental health problems, later had an abortion and she was unable to prove Spencer was the father, Mr Kemp said.
The court was told the victim had since been detained in a secure psychiatric unit and attempted to take her own life more than 20 times.
Spencer admitted charges of inciting a child to engage in sexual activity in relation to the five-year-old girl.
He also admitted sexual activity with the 15-year-old along with possessing, making and distributing indecent images of children between July 2011 and his arrest in August 2014.
On Monday, Recorder Nicholas Syfret QC ordered him to remain on licence until 2031.
He said: "These were monstrous offences. I have no hesitation in finding that you are dangerous."
