A court heard that an off-duty police officer raped a woman by the side of the road after showing his warrant card and questioning her about her driver’s license.
Jurors heard that Metropolitan Police officer Paul Hoile was drunk at the time of the July attack in Shropshire.
He is accused of stealing the woman’s phone before assaulting her.
The special constable denies several charges and claims that the sexual activity was voluntary.
The 40-year-old, of The Chase, Benfleet, Essex, has pleaded not guilty to misconduct in public office, three counts of oral and anal rape, and causing a person to engage in sexual activity without consent at Wolverhampton Crown Court.
Prosecutor Caroline Goodwin KC said the officer was staying in the Shropshire area and approached the woman with a friend.
She said Mr Hoile abused and was “hiding behind” his police powers in speaking to the woman as she prepared to drive away from him and his friend.
“In drink, he was acting as if he was in charge, like a police officer… questioning her about her [driving] licence,” Ms Goodwin said.
“She asked for his warrant card and he produced it – he kept his thumb over where his name was.”
The woman began Googling the powers of a special constable and information given to her by Mr Hoile before he asked for her name, which she confirmed, according to the court.
She then walked away after hailing a taxi, but he followed.
“He was drunk, and you’ll hear her say she thought he was capable of anything,” Ms Goodwin explained.
Mr Hoile was accused of telling the woman she would be in “more trouble” if she hit him before she “did what he wanted” despite being sick.
Jurors were told the woman was left “confused, upset… emotionally distraught”.
“But in those moments after, when she thought about what had occurred, she had sufficient [wits] about her that, in spite of the deeply personal nature of these assaults, she made an immediate complaint,” Ms Goodwin said.
After Mr Hoile’s arrest, he told officers he had consumed numerous drinks, including about five double vodkas.
He said he had engaged the woman in “general chit chat about sex” before she performed oral sex on him.
The trial, estimated to last a week, continues.
