Jason Mark Le Chevere (43) of St Saviour has been in La Moye since he was found guilty by a Royal Court jury last November.
Over the course of his four-day trial, the jurors heard evidence from the two victims via pre-recorded interviews with the police and by live video-link.
Due to their young age, the victims did not appear in the court.
The court heard that they ‘were terrified’ of Le Chevere, who was described during the trial as an ‘alpha male’ with a temper.
Le Chevere was convicted of two counts of rape and 11 indecent assaults against two victims, who were under the age of 13 at the time of the abuse.
In outlining the case, Crown Advocate Simon Thomas said Le Chevere’s sexual assaults on his young victims have left them suffering from anxiety and low self esteem.
Reports from a social worker and clinical psychologist who worked with the girls said they were at high risk from long-term, mental health and psychological difficulties.
The girls self-harm and have trouble sleeping as they are plagued by memories of the abuse, they mistrust adults and have trouble making friends, the court heard.
One girl said in a victim impact statement that she fears she will never be able to have a relationship with a man as a result of of what happened and thus will not be able to have children.
The other victim was said to show high levels of aggression and described her abuse as Le Chevere’s attempt ‘to break her’.
While delivering the court’s sentence, Commissioner Sir John Saunders said it was clear that both girls have ‘suffered greatly as result of these offences’ and they will suffer to some degree for the rest of their lives.
