A SICK paedophile was jailed yesterday after telling a 13-year-old girl he wanted to have sex with her — and would rape her child if she fell pregnant.

Geraint Kristopher Jonson engaged in warped conversations with young girls online.

But Swansea Crown Court heard that the beast remains unrepentant and does not believe he has done anything wrong.

The 24-year-old has refused to engage with efforts to tackle his vile perversions, WalesOnline reported.

Ian Wright, prosecuting, said Jonson handed police his passwords and detectives accessed logs to the video call service Skype.

Chat history showed Jonson initially communicated with a 13-year-old girl about innocent subjects like computer games.

But the perv then moved conversations into "sexual" topics and began paying his victim compliments.

The court heard Jonson began asking her to expose herself on camera while he performed sex acts on himself.

His victim - traced to the Humberside area - has been spoken to and realises how she was the victim of Jonson's sick grooming.

But jurors heard how the girl had believed that Jonson genuinely wanted to be her boyfriend.

Another chat log showed Jonson engaging in sexual conversations with what appeared to be a 13-year-old girl in the US.

He had also asked her to perform sex acts on camera — adding that if she fell pregnant and had a daughter he would want to have sex with the child too.

And he told her about films he had watched of the incestuous rape of a four-year-old girl by her father, the court heard.

A third chat log discovered by cops involved what appeared to be a 10-year-old girl.

But unbeknown to Jonson the profile was in fact being run by an adult male.

During these chats, Jonson again talked about impregnating the "girl" and then abusing any daughters they may have had.

He also told the "girl" he wanted sex with her while she was wearing her primary school uniform.

Detectives also found more than 150 indecent photographs and videos of children on Jonson's computer and phone — including 39 of the most extreme Category A images.

Jonson, of Heol Gwyrosydd, Penlan, Swansea, pleaded guilty to a total of 11 counts of possessing indecent images, inciting a child to perform sexual acts, attempting to incite a child to perform sexual acts, and engaging in sexual acts in the presence of a child.

He was handed a 10-year extended sentence at Swansea Crown Court on Friday.

John Tarrant, defending, said pre-sentence reports showed little evidence that he accepted he needed help.

Judge Geraint Walters described the case as one of the most disturbing of its kind that he had seen — due to Jonson's refusal to admit his actions had been wrong.

He said pre-sentence reports made for "very disturbing reading".

A psychiatrist concluded Jonson was "suffering from paedophilia" and was committed to carrying on with similar communications with young girls in the future.

Judge Walters told Jonson: "You have given no indication whatsoever of being in anyway remorseful.

"You consider there is nothing wrong with what you have been doing — let me tell you, it is very wrong."

Jonson will serve seven years in custody and three years on licence.

He will also be on the sex offenders' register for the rest of his life, and will be the subject of an indefinite sexual harm prevention order.
