Quote:He said that he had woken the woman at 5.30am when he went to get a glass of water from the kitchen and to switch off the TV.
Abdulaziz claimed the teenager pulled him onto her and placed his hand between her legs. But he said she become angry when he had offered to call her a taxi and stormed into the bedroom to wake her friend.
He is then said to have changed his story after DNA tests found traces of his semen.
Mr Davies said: "That caused him to be re-interviewed in May this year and he was confronted with that finding.
"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. You may consider, members of the jury, him changing the account he was giving."
Abdulaziz, of Maida Vale, denies rape and the trial continues.
