A woman accused of a stabbing murder told a friend "oh babe, you should have felt that, it felt so good", a NSW jury has been told.
Lily Ridgeway, 22, has pleaded not guilty to murdering Jason Adams, 27, outside a Raymond Terrace home, north of Newcastle, on February 29, 2020.
In the NSW Supreme Court on Wednesday, prosecutor Brian Costello opened the crown case telling the jury Mr Adams had been bailed to live at the home of Ridgeway's friend, Nikita Louise Hanson.
He was told to leave on the evening of February 28 but returned early the next morning after a series of increasingly acrimonious text messages between him and Ms Hanson.
Ridgeway, who was also at the address, went outside where she fatally stabbed him once, Mr Costello said.
"The crown case quite simply is that the accused went outside to confront Mr Adams with a knife, not doing so in acting defensively at all.
"When he began to taunt her, saying 'stab me', she did exactly that."
He expected Ms Hanson would tell the jury that Ridgeway then said to her: "Oh babe, you should have felt that, it felt so good" before fleeing the scene.
The Crown contended Ridgeway had deliberately stabbed Mr Adams, intending to inflict really serious injury, and was not acting in self-defence.
She told police she saw a phone in one of Mr Adams' hands and a "reflection" in the other which she thought might be a knife, that he grabbed her and she pushed him and then blacked out.
She said she went into "survival mode" and must have acted in self-defence.
No knife was ever found on or near Mr Adams, and no witness saw him with one, Mr Costello said.
He acknowledged Ridgeway had previously been the victim of serious domestic violence, but said the events had not involved a domestic relationship or any preceding act of violence.
Her barrister Madeleine Avenell SC told the jury it was not disputed that at the time he suffered a single knife wound that Ridgeway was holding the knife.
But the defence did dispute that she deliberately caused the wound, that she intended to at least cause him serious harm and that she had not acted in circumstances of self-defence or defence of Ms Hanson.
Before Ms Hanson began her evidence via AVL from prison, Mr Costello told the jury her custody was "entirely unrelated" to the case.
She said she met Mr Adams through friends of friends and after a driving unlicensed matter and some warrants he got bailed to live at her house a few days before his death.
They got on OK to start with, but by the second day he was "making movements on me which made me uncomfortable.
"I didn't want a relationship with him.
"I didn't want anything from him but he didn't listen to that."
He grabbed her face towards him so their lips would meet, he touched her leg and rubbed her on the back.
She asked him to leave and Ridgeway contacted two men, including her relative Mark Russell, to escort him from the house.
"They asked him to leave but he sat there dumbfounded, not understanding what they were saying," she said.
Eventually, they helped him up but it was "his decision to get out as well" and he said he would go, knowing he was not welcome.
She will continue her evidence on Thursday.
