Joelle Barozzini, a foster mum is accused of having s*x with a 16-year-old under her care more than 500 times, Daily Star UK reports.
The 46-year-old married woman allegedly pretended to be his girlfriend in public, claiming she had a disease which caused premature ageing.
According to Daily Star UK, the brunette is said to have started the abuse by slipping his hand up her thigh on a basement couch during a party when he was 16.
Speaking to the court, the victim said: “I was nervous, she kissed me. She grabbed me by the hand and pulled me into her room.”
They had s*x with the bedroom door open while Barozzini’s husband was asleep on a sofa, he said.
He added: “I was just really scared that somebody was going to see. I was kind of frightened. I really didn’t know what to do.”
He said he and Barozzini had s*x “hundreds of times” in several rooms of her five bedroom home and in hotels when she took him away for weekends.
“I was honestly too nervous to say no,” he testified. “Every single time, just about, would be against my will.”
Barozzini reportedly texted him nude selfies, gave him alcohol and said things such as: “We’re boyfriend and girlfriend.”
The alleged victim, now 24, said he tried to tell a relative and a pal about the abuse but they did not believe him.
He added “there were sweet moments,” and Barozzini was upset when he moved out in 2013.
Prosecutor Jim Lazar accused Barozzini of using “psychological coercion” to keep the teen from telling anyone about the sex in Greensburg, Pennsylvania.
Those circumstances “would have clearly had him feel absolutely helpless to reject or stand up to or put a stop to or get away from Ms Barozzini’s advances, and that continued for years,” Mr Lazar told the preliminary hearing.
“At some point, when you have nowhere to go, you became sort of accustomed to the circumstances that you’re in and you attempted to make the best of them.”
Barozzini will now stand trial on on a string of charges including rape, sexual assault and corruption of minors.
