Scott Kelly, aged 38, of Colmbanus Estate, Milltown, Dundrum, Dublin, pleaded guilty to one count of raping and two counts of sexually assaulting the 19-year-old woman on February 28, 2013, in Dublin.
Mr Justice Paul Carney suspended the final two years of a six year prison sentence after noting the mitigating factors of an early guilty plea and the absence of previous convictions.
He also ordered Kelly be registered as a sex offender.
Garda Stephen Mullen told Roisin Lacey, prosecuting, at the Central Criminal Court, that the woman was visiting Ireland and met Kelly who offered to show her around the city.
They decided to go to a number of free events around the city. They both drank several glasses of red wine and then went back to his apartment.
Kelly asked the teenager if he could draw her as he wanted to base a character in his book on her, and she said yes. They had more wine and shared a joint.
The girl started to feel sick and dizzy. She told gardaí she then blacked out on the man’s bed, wearing all her clothes.
When she regained consciousness, she realised her shoes, leggings and pants had been pulled off.
She said she was lying in the foetal position and the accused was touching her. She said his finger entered her vagina and that she was shocked and in a daze.
Kelly performed oral sex before raping and sexually assaulted her.
Damien Colgan, defending, said Kelly pleaded guilty and expressed great remorse for his actions. He has no previous convictions.
