A judge says a man who committed a sexual crime against a young teenager "completely destroyed" the victim's life.
Stephen Norman, now 23, was sentenced in the County Court in Bendigo on Thursday after pleading guilty to the sexual penetration of a child under 16.
Judge Douglas Trapnell sentenced Norman - who was 17 at the time of his offence - to two years' imprisonment, with one year cumulative on a four-and-a-half year sentence he is already serving.
The new sentence extends Norman's non-parole period by eight months, meaning the earliest he will be eligible for parole is May 2020.

The day of the offence, the 14-year-old victim and Norman were at his house in the Echuca area and began to kiss.
They were both lying on the bed when Norman said, "Are you ready to lose your virginity?" to which the victim replied "No, I want to stay a virgin".
Norman then penetrated her and said, "Too bad, now you're not".
He requested other sexual acts from her, which she refused, but continued penetration.
The victim said she "just laid there".
"She says that she wanted to kill herself, that she felt dirty, was ashamed and just wanted to go home," Judge Trapnell said.
He said it was clear from the victim impact statement that Norman's offending had a "devastating effect on the victim".
The statement described how she experienced serious mental health issues, school life became unbearable and she became socially isolated.
The incident continued to affect her, she said.
"This is simply another example of the extreme trauma suffered by the victims of child sexual abuse," Judge Trapnell said.
"For a few minutes of sexual gratification, you've completely destroyed this young woman's life."

He noted the matter was due to go to a contested committal hearing before police and the defence counsel became aware of a phone call Norman had with his mother the night before.
Norman's mother said, "Do your lawyers know you actually did it?" to which he replied they knew but "they can't go against me".
After consultation with his lawyers, Norman pleaded guilty in the Magistrates' Court.
Judge Trapnell said he assessed Norman's moral culpability in his offending as high.
"Your contumelious disregard of her clear and forceful protestations makes this a serious example of this offence," he said.
Norman had committed no other offences prior to this incident, but he since had a criminal history dating back to 2013, which comprised mostly dishonesty offences and some involving violence.
Judge Trapnell accepted Norman's guilty plea and the benefits it brought, but found there was insufficient evidence of true remorse on his part.
He said delay was a significant factor and although it was not uncommon in such cases, it meant Norman was denied the more "benevolent" sentencing regime of the Children's Court.
Norman had taken positive steps towards rehabilitation while in custody, Judge Trapnell said, and had a reference that spoke of him as a natural leader to whom people gravitated.
He said he also accepted that Norman's time in custody had provided a salutary lesson.
Following his release from prison, Norman will be a registered sex offender for seven and a half years.
