Michael Le Cras, 44, admitted the offence in the Royal Court where he was told by Judge Catherine Fooks that he should feel shame and remorse for what he had done.
‘The victim has to bear psychological scars for the rest of her life, and you have to bear the responsibility for that,’ she said.
Last summer, Le Cras was out drinking with his partner and during the evening he took the drug Gabapentin.
His partner left and he joined another group, who went back to one of their houses at the end of the night.
Le Cras had not planned to stay over and he was directed to take a spare bedroom while the victim slept on a mattress on the lounge floor. He asked to sleep on the sofa but the woman said he should go back to the bedroom.
In the early hours of the morning the victim woke up to Le Cras sexually assaulting her.
She ran into another room, crying uncontrollably, and was physically sick due to shock.
By the time other people reacted and went to the lounge, Le Cras had gone. The woman reported the offence the next day.
When Le Cras was arrested he had already been beaten up, understood to be an act of retribution.
In interview he stayed silent, but he later accepted responsibility for what had happened, claiming he had no recollection of it.
Since admitting the offence, he had addressed his use of alcohol and drugs.
