A woman has been jailed for four years for encouraging a 12-year-old girl to have sex with her lover.
Lundon's actions were described as depraved by the sheriff
Caroline Lundon, 40, from Morayshire, was described as "utterly depraved" at Elgin Sheriff Court.
She admitted that she had sex with the man in the girl's presence and had encouraged the child to do the same.
Last year, Ernest Graham was jailed for six years for having sex with the girl and permitting her to watch while he had sex with Lundon.
Sheriff Ian Cameron told Lundon, a development officer with Highlands and Islands Enterprise for 19 years, that she had done terrible damage to the child.
He said: "The fact that you've held a responsible position in HIE to support your family suggests you are not a person of restricted intellect, quite the opposite.
"It is extraordinary in these circumstances that a person of your calibre did not realise Ernest Graham was being manipulative to you and the girl, and that you succumbed to this manipulation.
"In any view your actions can only be described as utterly depraved."
The court heard that Graham, 46, owned riding stables and was known for his horse-whispering techniques.
The Princess Royal visited the Lossiemouth stables as President of Riding for the Disabled three years ago and congratulated Graham for his work.
The girl had begun riding lessons with him at the age of nine but by 12 was being used for sex.
The court heard that a series of offences took place at Lundon's cottage but on one occasion Lundon and Graham involved the child in sex in a car on the A96 after celebrating her 13th birthday in Aberdeen.
Graham was jailed for the sex offences last year but for legal reasons that could not be reported until Lundon had been convicted.
Sheriff Cameron told Lundon on Wednesday: "What you did was the ultimate betrayal of trust, the harm and the possible psychological effects you may have done to this girl is incalculable in the long-term."
