A millionaire property developer accused of raping a teenager while she slept claims he accidentally penetrated her when he fell on top of her, a court has heard.

Southwark Crown Court has told Ehsan Abdulaziz allegedly forced himself on the 18-year-old on the sofa of his Maida Vale flat.

The 46-year-old met his alleged victim in the Cirque le Soir nightclub in London, where she had been with a friend he had known for several months.

He offered both women a lift home in his Aston Martin in August last year, before inviting them into his flat and taking the woman he knew into the bedroom for sex, the court heard.

The next thing the alleged victim claims to remember is waking up early in the morning with Abdulazziz on top of her, forcing himself inside her.

"She woke up with the defendant kissing her and his penis in her vagina," Prosecutor Jonathan Davies told the court, The Times reports.

"She said: 'What are you doing?' and he said 'It's fine', indicating that her friend was asleep.

"She got up to find her friend, tried to wake her but couldn't, she then tried to get out of the flat as quickly as she could."

She then phoned the police.

The court was told that when Abdulaziz was arrested he responded: "She'll have to prove it."

He first claimed to police the teenager had pulled him on to her and placed his hand between her legs. However, when DNA tests found traces of semen he was re-interviewed in May.

The Daily Telegraph reports that Mr Davies told the court: "On this occasion he said after he had sex with the complainant's friend his penis was still erect and he had semen on his hands when he went into the living room.

"He said in the second interview she pushed his hands down on to her vagina. He said that he did fall onto her and his penis may have penetrated her vagina."
