Carolee and Albert Hickman, from Vale of Glamorgan, terrified the girl by telling her she was part of a black magic witches covern - drinking her blood and forcing her to have sex with Albert.
The victim, who is now 53, was so traumatised she blocked out the abuse until it came flooding back in 2011 during counselling.
In court she spoke of how Hickman sucked blood from her thumb after cutting her with a ‘bejewelled knife’ and threatened to kill her mother if she didn’t co-operate.
Shockingly, Albert’s wife Carolee held down the girl while he raped her.
In a statement from the victim, she said the couple had completely destroyed her life and she was unable to sleep with the light off.
‘My life has been destroyed at their hands.’
‘Forty-two years ago a little girl met two evil people who took advantage of her.’
‘My life has been destroyed at their hands.’
Sentencing the couple this week, the judge said:
‘You groomed her and gained her trust, you told her you had supernatural powers and that she was the ‘chosen one’ and you put the fear of god into her.’
‘It was a specific targeting of a vulnerable victim and threats were made which petrified her.’
Albert Hickman had previously served 10 years in prison for raping a young girl in 1982.
His wife had also held down the girl in this case.
