Former St Helier resident, Derek David Allen, was found guilty in December of charges of rape and indecent assault after a three-day trial.
Outlining the case at the 41-year-old's sentencing hearing on Thursday, Crown Advocate Matthew Maletroit said Allen had invited the victim to his home last March for a 'drinking challenge' and the two drank alcohol and smoked cannabis.
The victim admitted that she had kissed Allen for ‘two seconds’ but said she then pulled away and repeatedly said ‘no’ but he paid no attention and continued to sexually assault her.
The victim said she 'froze' and tried not to think and just stared at his wardrobe.
When he stopped, she dressed quickly and fled to the police station barefoot to report what had happened.
Crown Advocate Maletroit said Allen has shown no remorse for his offences.
He said the victim was 'particularly vulnerable' before the sexual assault and has since suffered severe psychological and emotional distress and been diagnosed with PTSD.
Crown Advocate Maletroit said Allen's offences were a 'gross abuse of trust which caused the victim severe psychological harm'.
