Roger Dawidowicz appeared in the County Court in Melbourne after pleading guilty to five child sexual assault charges.
Over several months, Dawidowicz preyed on the child by creating fake games, including telling the young girl "close your eyes, I have a surprise for you", the court was told on Friday.
"This would no doubt have created an expectation in [a child] about what might occur," Judge Stewart Bayles said.
"What did in fact occur would have been completely outside of her expectation and outside of her experience of the world."
Dawidowicz told the child it would be like a fun game or something before he sexually assaulted her.
Another of the assaults was committed by Dawidowicz while he was driving the child home from Timezone.
"You had full control over her in the senses of both time and space," Judge Bayles said.
"You used that control to inflict this conduct upon her in circumstances where she was particularly powerless."
His young victim said she was scared of Dawidowicz and feared he would her hurt if she didn't do what he asked.
"She describes her confusion and lack of understanding when things first started happening," the judge said, reading her statement to the court.
"Looking back now, she says she blames herself for not being able to stop it. She feels ashamed.
"These events have changed the way she sees the world."
He sentenced Dawidowicz to four-years and eight-months in prison and ordered he serve a minimum of two-years and eight-months before he will be eligible for parole.
"I must impose a sentence that denounces this conduct, punishes you for your offending and deters both you and others who may be minded to offend in this or any similar way in the future," Judge Bayles said.
