A North Korean defector has told of Kim Jong Un’s teen sex slaves, lavish caviar lunches and gory public executions.

Hee Yeon Lim, 26, is the daughter of a high-ranking soldier from Pyongyang and a member of the regime’s inner circle.

But when her father, Col. Wui Yeon Lim, 51, passed away, she and her family decided to flee the country in 2015.

Now in South Korea, Hee Yeon has spoken of what life was like inside the secretive rogue state.

She told the Mirror she saw “terrible things” in her home city of Pyongyang despite her family’s relative privilege.

She said officials came to her school to pick out teen schoolgirls to work at the chubby dictator’s homes.

The escapee said they would only choose the prettiest girls, who were taught to feed him caviar and massage him.

If they refused, they would “disappear,” she said.

Hee Yeon — who has met the despot — also told how he would dine out on imported delicacies like caviar and Chinese “bird’s nest soup,” which can cost $2,700 a kilo (2.2 pounds).

And she described one occasion when she was forced to watch as a group of 11 musicians accused of making a pornographic video were slaughtered.

Hee Yeon told how she and her classmates were ordered out of their classrooms in the middle of the day by soldiers who took them to a stadium at the city’s Military Academy.

She said the hooded and gagged victims were brought out and tied to the end of anti-aircraft guns in front of some 10,000 spectators.

The escapee then recalled how the guns were fired one by one, saying: “The musicians just disappeared each time the guns were fired into them.

“Their bodies were blown to bits, totally destroyed, blood and bits flying everywhere.”

Afterward, Hee Yeon said tanks moved in and ran over the pieces of the victims’ bodies.

She added: “The tracks of the tanks were run over the remains and blood repeatedly, over and over again and made to grind the remains, to smash them into the ground until there was nothing left.”

Left feeling “desperately ill” after the grim spectacle, she later decided to escape the country.

The family paid smugglers to drive them across the border to China, before traveling on to South Korea via Laos.
