During the fifth day of the Jodi Arias sentencing retrial, Arias' defense team presented the jury with sexually explicit evidence of the convicted boyfriend killer's sex life with the victim, Travis Alexander, before he was murdered.

Arias, 34, was convicted of the first-degree murder of her ex-boyfriend Travis Alexander in May 2013. According to medical examiners, Arias stabbed him 27 times, primarily in the back, torso and heart in his Phoenix home in 2008. She also slit Alexander's throat from ear to ear, nearly decapitating him, and shot him in the face before she dragged his bloodied corpse to the shower. However, the jurors failed to reach a unanimous decision on her sentencing. As a result, the retrial will determine whether she should be sentenced to death, life in prison or life with a chance of release after serving 25 years.

On Tuesday, Arias' defense attorneys presented the jury with graphic testimony that included pornographic photos that they took of one another, explicit text messages and racy phone conversations. At one point, the defense played a 40 minute phone sex conversation that the lovers shared recorded on Arias' phone, reports USA Today. During the kinky recording, Alexander talked about raping her and tying her to a tree and they both made moaning sounds as if they were having an orgasm.

"The highlight of today was the sex tape between Travis Alexander and Jodi Arias. It's very X-rated," said courtroom blogger Jen Wood to Phoenix TV Station KTVK.

"The jury did a really good job of sitting there, pretty stone-faced, either looking down or looking straight ahead while they had to listen to a very salacious conversation," added Wood.

According to Wood, Arias' defense attorney likely played the tape in hopes of countering the prosecution's claim that Alexander was afraid of Arias.

"I think his goal was to show that Travis was very sexual, that he was very into it," she said.

The defense attorneys will begin to present evidence to the jury when the trial resumes Thursday in effort to persuade them to sentence her to life in prison, rather than capital punishment.
