A man sexually assaulted his girlfriend's 15-year-old daughter for months after watching a soap where a character was sleeping with a mum and daughter.
The man, then 27, looked "pointedly" at the teenager and said: "Oh isn't he lucky!" after watching the storyline on TV together.
Manchester Crown Court heard how later on, the man coerced the girl into having sex with him under the nose of the girls' unwitting mother.
He cannot be named to protect the identity of his victim.
During the campaign of sexual abuse, the man told the youngster how much he loved her and at one stage she mistakenly feared she had become pregnant.
The girl, from South Manchester kept the abuse a secret until informing her aunt in 2019.
Now a married mother of one, aged 29, she told police: ''I was frightened about what would happen if I told her mother as I thought she would hate me.
''I felt ashamed at the time and I still I have let my mum down by what has happened. I am now struggling with my mental health.
"Because of what happened, I have kept my husband from our child, not letting him bath the child or change its nappies.
"I'm even worried about allowing friends to come for sleepovers. A part of my life has been negatively impacted."
At Manchester Crown Court, the man, now 42, was jailed for eight years after he pleaded guilty to sexual activity with a child and indecent assault.
The court heard the young girl had developed a ''schoolgirl'' crush on the man after he moved in with her mother at their family home in the year 2000.
She later temporarily moved in with her grandmother when she told her mother he had been touching her, but subsequently returned home in 2006.
Paul Treble prosecuting said: ''The defendant began to pay her compliments, telling her that she looked "grown up".
He would give her alcohol and made a comment about a character in a soap opera having slept with a mother and a daughter, telling her: ''Oh isn't he lucky'' and looking pointedly at her.
''One day, she was alone with the defendant while her mother was in the bath. He gave her a cannabis spliff, and kissed her and later that night they had sexual intercourse.
"This was the first of many occasions – at least seven - and it went on for around three or four months.
''The defendant told the girl he loved her and did not use contraception. On one occasion, she believed that she was pregnant, but this turned out to be a false alarm."
The court heard that the defendant told the girl to keep their sexual encounters as "our little secret."
''The final occasion was shortly after New Year of 2007, following which she told the defendant that they had to stop," Mr Treble said.
"The defendant told her, "If this ever came out, it’d be you that’d be in trouble".
The man voluntarily attended Longsight police station in October 2019 for interview.
He said he did not wish for a solicitor as he "had done it" and was said to have made ''frank admissions.''
In mitigation defence counsel Jonathan James Turner said: ''There was no blackmail and no threats in this case.
"There was a pregnancy scare, but it was a scare. He has a new partner but the consequences of these convictions are that he lost his entire family.''
Sentencing, Judge Miss Recorder Anna Vigars QC told the defendant: ''You gave her alcohol and cannabis and you caused serious damage to her mental health.
"You took no protection to avoid pregnancy and emotionally exploited her, telling her you loved her and telling her she would be in trouble if she made it public.''
The man was also ordered to sign the Sex Offender Register indefinitely and was made subject of a Sexual Harm Prevention Order.
