Michael Jackson's 15-year-old accuser told the court Thursday that the pop star molested him twice.

The teen told the jury about his first visit to Jackson's Neverland Ranch, how the singer slept in the same bed with him, and showed him pornography.

He testified that he and Jackson, 46, were alone on the singer's bed after drinking both times.

Jackson talked to him about touching before each incident, he said, and that the touching lasted about five minutes.

The accuser said he felt "weird" and "embarrassed" afterward, but the pop star insisted it was natural.

He also recounted that Jackson had shown him sexually explicit magazines found in a briefcase belonging to one of the singer's employees.

He said Jackson derided the employee for having the magazines, but that he and Jackson looked at them for 30 minutes to an hour.

The accuser also said Jackson gave him alcohol in a Coke can, calling it "Jesus juice" and not to tell anyone.

In an account that differed from earlier testimony by his 14-year-old brother, the boy also told the jury that he and his brother were once on Jackson's bed when the singer came in naked.

The accuser's brother had said Jackson came in naked and aroused and said it was "natural."

The accuser, however, made no mention of Jackson being aroused. He also did not recall the singer having said anything.

Jackson AWOL

The drama began today even before any testimony was given.

Jackson was nowhere to be found when the morning's proceedings were scheduled to begin.

A clearly angry Judge Rodney Melville responded by issuing a warrant for Jackson's arrest, saying he would revoke his $3-million US bail unless the performer appeared in court within an hour.

His lawyer, Thomas Mesereau Jr., told the court that the pop star was being treated for a serious back problem.

Jackson finally arrived by SUV five minutes after the deadline passed. He was dressed in a suit jacket over pyjamas and slippers, walking slowly on the arm of one of his bodyguards. He was able to turn to wave to fans on his way in.

Melville resumed the trial without arresting the late-arriving defendant. Lawyers met with the judge in chambers before court resumed but it is not known what admonishment, if any, Jackson received.

This is now the heart of the case, and if the jury believes this boy through his testimony, then Jackson will be convicted.

"The evidence of the accuser for the next three days or so is really going to determine Michael Jackson's fate," legal analyst Steven Skurka told CTV's Canada AM Thursday. If he doesn't do well on the witness stand, Jackson will be acquitted."

Jackson's defence contends the accuser's family has a history of filing false claims to get money.
