The girl, who is now 21, was just 13 years old when she went to live with Rob and Marie Johnson after her mother died, CBS 12 reports.
The alleged abuse started almost immediately, with the couple telling the young girl within the first week of her arrival that she had to have sex with them in order to become a part of the family.
"She was extremely detailed as far as the systematic abuse that occurred over a rather long period of time," said Det. Steve Reuther with the Port St. Lucie Police Department.
The girl told police that the abuse occurred from the time she was 13 to when she was 18, according to an arrest report obtained by CBS 12.
"She was told to call Robbie 'master' and that she was there to serve them," the arrest report states.
The girl resisted at first, but then Marie allegedly became violent, holding her "by her throat" until she "agreed to have sex with them," according to the report.
The girl also said that Rob read her Bible passages to justify the alleged crimes.
"Rob would read a passage about people in the Old Testament having multiple wives and therefore, he believed it was okay," the arrest report states. "He would also justify beatings by saying the Old Testament says it is okay to physically strike their wives."
The couple allegedly kept the girl from going to school and homeschooled her instead. She also wasn't allowed to use the phone "because Rob and Marie did not want her talking to anyone," according to the arrest report.
And when she went to the doctor, "Rob and Marie would rehearse what she would say to the doctor when he asked about sexual activity. She was supposed to tell the doctor she was not having sex when the doctor asked."
The girl finally escaped the house by calling her grandmother, who bought her a plane ticket to go back to Ohio, police said.
Rob and Marie are charged with felony sexual assault. They have not yet entered a plea, but are free on bail after posting a $60,000 bond.
