The teenager was evicted soon after because she was too drunk. She fell over in the pub carpark and collapsed.
Penese, who was also out on the town, found her there and tried to get her into a taxi but the driver refused the fare. At that time, the girl was so drunk she could not stand.
He waved down a passing car and the driver took them to Penese's home in Hornby, where he took off her clothes and had non-consensual sex with her.
When the girl woke she gathered her clothes and left without waking him up. She phoned her father from a service station and then the police were called.
Penese initially denied having sex with her, but three days later he admitted that he had undressed her and had sex with her.
The girl's mother told The Press she was glad Penese had admitted to the crime and avoided a defended hearing.
She was disappointed Bush Bar staff let her drunk, under-age daughter in and then kicked her out later in the night.
"It seems like a real lack of a duty of care. She was so ripe for any kind of predator. It was bad enough what happened, but at least we got her back alive."
She said her daughter was recovering from the ordeal and remembered snippets of the night, including the attack itself.
Police southern area commander, Inspector Malcolm Johnston, said he was also disappointed in how the security staff behaved. "I would have expected, and I suspect the owner would have expected, a different response bearing in mind that within 10 metres of the bar there's a line of taxis."
Bush Bar beverage operations manager Ben Tolhurst told The Press that while he could understand the mother's anger the staff were "just following what the law states" by evicting intoxicated people from the premises.
"My staff do their best to make sure we have zero tolerance for anyone being intoxicated on the premises. We are not allowed to have people showing signs of intoxication on the premises at all.
"It's tough to say what the right or wrong thing to do was on the night."
