A woman has been jailed after she helped a man to rape a girl under the age of 13 twice.
Gemma Hill, 33, exchanged messages with boyfriend, Stephen Arnopp, in which they discussed how he would rape the girl.
They were also found to have plotted the rape of a nine year old girl.
Arnopp was jailed for 11 years for abusing and twice raping the girl under 13 in Welwyn Garden City, Hertfordshire, and his victim’s underwear was found at his home.
Hill, from Hatfield, was jailed for six years because she told the girl not to report the attacks to police.
However, the girl told teachers and the authorities were informed.
Judge Marie Catterson, who said Hill had an ‘extremely low’ IQ, said the victim had suffered ‘incalculable’ long-terms effects likely to be ‘difficult and profound’ after the pair admitted all charges against them.
Sentencing Hill, she said: ‘You were evasive, pretending you knew nothing.’
She said Arnopp’s abuse required ‘sustained and significant planning’ and it was fortunate the pair were arrested before attacking the second girl.
The judge made a Sexual Harm Prevention Order banning the pair from contacting the victims and from living in a house or having any unsupervised contact with girls under the age of 18.
Both defendants pleaded guilty to the charges against them.
Arnopp was given two concurrent 40-month sentences for two counts of conspiracy to commit sexual activity with a child under 13 and was jailed for eight years consecutively for two counts of raping a child under 13.
He was also sentenced to one count of inciting and one count of causing a child to engage in sexual activity, receiving four months concurrent to his other sentences and received eight months, also concurrent, for sexual activity with a child under 13.
Hill received two concurrent four and a half-year sentences for two counts of conspiracy to commit sexual activity with a child under 13 and a consecutive 18 month sentence for cruelty to a person under 16.
