Marke allegedly threatened to break her kneecaps if she told anyone, according to the woman.
Zara Phythian, who plays Doctor Strange, and her husband Victor Marke have been accused of several sex offences, including having intercourse with a 13-year-old girl after grooming her.
The pair has been charged with 14 counts of sexual behaviour with the minor, who is now an adult.
The claims have been disputed by Ms Pythian, 36, and Mr Marke, 59.
The abuse occurred between 2005 and 2008, when the woman was between the ages of 13 and 15, she told the police in an interview aired in Nottingham Crown Court.
She said she looked up to Ms Phythian, who at the time was a martial arts instructor in Nottinghamshire with her husband.
They weren’t married at the time.
Ms Phythian allegedly provided her drink and urged her to have oral sex with Mr Marke, who then had sex with both of them, according to the woman.
“I felt that was wrong, but I didn’t know how to get out of it or say anything,” she said to the police, according to BBC News.
“At the time, I recall trying to imitate Zara’s reaction since I looked up to her and wanted to be just like her in every aspect.”
The woman reportedly told the court that Ms Phythian “coaxed” her to improve her sexual activity and that she had intercourse with Mr Marke roughly 20 times, according to the Nottinghamshire Live newspaper.
Mr Marke allegedly threatened to shatter her kneecaps if she told anyone, according to the lady.
She told police, “He basically stated nobody would believe me if I told them anyhow.”
“They’ve always had a stranglehold on me.”
Mr Marke is also charged with four further counts, including indecently abusing a child in regard to another woman who was molested between 2002 and 2003 when she was 15 years old.
The woman also filed a police report.
Mr Marke was married to another woman at the time, according to the court.
His first marriage had ended because he was having an affair with Ms Phythian, a teenager at the time.
