Members of the North Korean national cheerleading squad — who have been featured gleefully rooting at the PyeongChang Winter Olympics — are systematically forced to have sex with high-ranking members of Kim Jong Un’s twisted regime, according to a disturbing report.

Behind the scenes, the troupe — dubbed the “Pleasure Squad” by insiders — are forced to perform sex acts on party leaders during their trip to the Olympics, a defector with knowledge of the sexual slavery told Bloomberg News.

“[The] troupe came here and performed with dances and songs, and it might seem like a fancy show on the outside [but] they also have to go to parties and provide sexual services,” said defector Lee So Yeon, a military musician who fled the country in 2008, during Kim Jong Un’s regime.

“They go to the central Politburo party’s events, and have to sleep with the people there, even if they don’t want it,” said Yeon, 42.

She added, “Those sorts of human-rights infringements take place, where women have to follow what they are told to do with their bodies.”

The perky and impeccably dressed cheerleaders are subject to an extreme vetting system based on their looks, family backgrounds and loyalty to the Workers’ Party, according to the outlet.

They are monitored 24 hours a day, even while they eat and use the restroom, according to the UK Metro.

Yeon’s account of the sexual slavery piggybacks on past reports in which female defectors from North Korea have described being “selected” to sexually service members of the political party.

In 2010, defector Mi-hyang said she was only 15 years old when soldiers in green uniforms stormed her classroom and chose her to become a sex slave for Kim Jong Il, the father of Kim Jong Un, according to Marie Claire magazine.

She was forbidden from seeing her family and forced to spend 10 years sexually pleasuring him, according to the report.

Lee Il-nam, a nephew of Kim Jong Un’s father, who defected in 1982, also detailed some of the “Pleasure Squad” parties in his book.

The parties, which were often held at the tyrant’s official home, included kinky games in which the women were forced to strip and shave their pubic hair, Lee Il-nam wrote in his book, “Kim Jong-il’s Royal Family.”

“The routine at the parties included eating, drinking and dancing, but usually ended with erotic games,” he wrote, according to News.com.au.

“A favorite was a game in which the losers had to take off clothes one by one. It was enforced, regardless of men or women. If they got heavily drunk, they also played a hair-shaving game. If men lost, part of their head hair was shaved, as if it was mown. For women, their pubic hair was shaved.”

Other parties would be devoted entirely to sex, he wrote.

When the cheerleaders “retire,” they’re often married off to elite guards and sometimes paid to keep quiet about the regime’s dirty secrets.
