Even in death, Michael Jackson can’t beat sensational charges of child sexual abuse – and stunning new court claims reveal the depths of depravity at the late King of Pop’s Neverland ranch. WARNING: GRAPHIC SEXUALLY EXPLICIT CONTENT

The most graphic accusations come from pop star Britney Spears’ former choreographer Wade Robson, a child prodigy who was once one of Jackson’s closest pals.

In shocking court documents obtained by The National ENQUIRER, Robson spells out in sickening detail the abuse he suffered at Jackson’s hands.

Robson claims he was just 7 when Michael made his first sexual advances in the star’s bedroom in 1990, as the Australian- born dancer’s older sister slept in the same room. The abuse continued for another two weeks, and then for a period of seven years.

During that time, Robson – now 31 and creative director for singer Demi Lovato – claims Jackson raped him and once forced him to pose naked on all fours like a dog!

According to the suit, the “Thriller” singer masturbated while watching Robson “from behind on all fours, naked, with his knees and palms extended like a dog on all fours.” Jackson would later tell him: “We can never tell anyone.”

While Jackson’s lawyers have blasted Robson’s accusations as “outrageous and pathetic,” the legal papers describe numerous sexual acts between them instigated by the late pop star. According to the documents, those acts include: “French kissing, rubbing Wade Robson’s penis, having Wade Robson rub (Jackson’s) penis, licking Wade Robson’s anus while (Jackson) masturbated using lotion,The King of Pop is accused of the mutual fondling of genitals” with hands and mouths and “mutual fellatio.”

Other acts listed in the suit include “lying on top of (each other) gyrating their genitals together, showering naked together,” and “penetration of Wade Robson’s anus with (Jackson’s) penis.” Jackson also showed Robson explicit adult pornography of nude women, men and boys, and “told Robson he loved him” and “called Robson ‘son,’” according to the suit. Jackson – who died June 25, 2009 of acute propofol intoxication – also pressured him to keep quiet about the abuse, Robson claims.

According to one court declaration, Jackson told him: “People are ignorant and they would never understand that we love each other and this is how we show it. If anyone were to ever find out, OUR lives and career would be over.”

Robson claimed that until 2012 he thought his relations with Jackson were mutual. “I did not believe that I was forced. I believed that I was a consenting participant in the sexual acts,” he said.

But after multiple nervous breakdowns, Robson realized he’d been systematically abused. He’s suing Jackson’s estate, which is reportedly worth as much as $1.5 billion.

A judge has yet to rule whether Robson’s claim will be allowed to proceed. Jackson was acquitted of four child sexual abuse charges in 2005.

Similar charges were dropped before going to trial in 1994, but Jackson reached a reported $20 million out-of-court settlement with his 13-year-old male accuser’s family.

According to a published report in 2013, Jackson forked out another $35 million to hush up the molestation of 24 other boys.
