Sefo said he went to get something from the room where she was sleeping, and saw her awake. He identified himself to her, before the woman performed oral sex on him. The pair then had consensual sex, he said.
He said the woman called him a different name, so he stopped and turned the light on. Afterwards, he said they continued to have sex before she asked him to stop and leave.
Under cross examination by crown prosecutor Nick Webby, Sefo admitted to lying to police when he was first questioned.
He told the court he had not interacted with the alleged victim at all before April 18 and 19.
Defence lawyer Malcolm English said Sefo voluntarily gave police a DNA sample. He said both Sefo and the woman had been drunk.
"People recreate things in their mind when they are drunk."
