A 36-year-old married father sexually abused a 13-year-old girl after telling her he would marry her and give her twin babies.
Mansour Savari made his promises in a series of secret text messages to the schoolgirl.
Newcastle Crown Court heard that he took the teenager to a friend's flat and engaged in sexual activity with her.
The Sunderland Echo reports that a friend of the girl became concerned and told the police what she knew about the contact between the pair.
Prosecutor Amanda Rippon read some of the dozens of text messages exchanged between Savari and the girl in which they discussed having a baby together, and what it would be called. It was then Savari told the child: 'I would love us to have twins'.
Savari, from Silksworth, Sunderland, entered a guilty plea to two charges of sexual activity with a child just before the trial started last month.
Sentencing him to three years in jail and ordering him to sign the Sex Offenders' Register for life, Judge Roger Thorn QC said his relationship with the girl had been 'appalling'.
"You engaged in the most appalling and inappropriate sexual relationship with a young girl who you persuaded you were in love with and she was in love with you," he said.
"Your victim was only just 13 years of age and by contrast you were 36.
"There had been here a significant period of grooming, promising, in effect a long-term relationship eventually which would be characterised by both marriage and children.
"That, of course, led ultimately to her seduction."
Savari's barrister said that it was his client's 'sincere wish that this young girl and her family recover from the trauma and difficulties they have faced through his offending'.
