"I thought it would get easier over time but it definitely hasn't. This will haunt me forever."
The girl said she experienced repeated flashbacks of the abuse and required sleeping pills to get any rest.
In November 2016, Espie – a "friend of a friend" - added her on Facebook.
It was no one-off. The court heard how the defendant had more than 2000 friends on the social-media website, many of whom were younger females.
He was "fixated" on having a younger girlfriend, Probation said, and he had broken up with someone in the past because he found out she was older than him.
"A lot of people would call you a sexual predator on social media," Judge Kevin Phillips said.
Espie was staying with family in Milton and the girl came over to visit another teen on December 26, 2016.
While Espie knew the boy had gone camping and would be away for days, he lured the victim inside, telling her he would be back within minutes.
"It was lie upon lie," Judge Phillips said.
"Clear premeditation, planning and deceit . . . to be able to position yourself where you could basically attack her."
Espie groped the girl.
"Skin on skin contact," the judge said.
The victim swore at him and told him to stop but the depraved violation continued until she managed to prise his arm away.
Crown prosecutor Craig Power stressed Espie had little insight into his crimes.
The defendant was assessed as having poor emotional maturity, "distorted thinking", poor decision-making and had issues with entitlement.
"There are very real concerns about possible future offending," he said.
While defence counsel John Westgate highlighted the fact his client had no previous form for sex offending, the judge agreed Espie was a threat to the public.
A report classed him as a high risk of harm to others.
It was crucial, Judge Phillips said, that the defendant complete the Stop Programme – specialised sex-offender rehabilitation.
But if he sent Espie to imprisonment, there would not be enough time for him to complete the counselling behind bars.
The judge therefore sentenced him to eight months' home detention with a condition he undertook the programme.
Espie was also slapped with 200 hours' community work and was ordered to pay the victim $4000.
Despite objections from Mr Westgate, Judge Phillips had "no hesitation" in placing the defendant on the Child Sex Offender Register.
