Hugh Hefner has passed away, yet some of his dark secrets linger on.

Despite no longer being linked with him, his past lovers are concerned that these secrets may come to light and damage their life.

According to The Sun, before his death in 2018, the Playboy tossed a concrete-lined casket containing his secret sex recordings into the sea.

In the documentary "The Secrets of Playboy," a top Playboy executive stated that the magazine's founder ordered his stockpile of covert sex recordings, including his orgy videos and nude photo collection, to be tossed into the sea.

Now, his former lover Sondra Theodore, who recently revealed how she saw Hefner having sexual relations with his dog, is concerned that additional hidden videos of him and his favorite bedroom sessions may still exist.

She believes Hef has other tapes, some of which may even contain rape and abuse.

In 2011, Sondra and Miki Garcia, the former head of promotions, allegedly put pressure on the magazine mogul and his lawyers to discuss the existence of recordings.

During his dying years, his guards allegedly emptied his archive, placed everything in a concrete casket, and dumped it off the California coast.

Sondra stated that Hef had taped anyone who walked into hat bedroom undressed - "Anyone who walked into hat bedroom undressed had tape on them."

"They knew they were there, and it kept everybody in order," she continued. They were worried about what might happen if word got out and everyone saw them."

Sondra also admitted in the documentary's last episode that she and Miki wanted Playboy to reveal information from the archive.

She became concerned about the tapes and what would happen if they suddenly surfaced.

"He was in his eighties, may die at any time, and who would have the key to access that panel?"

Sondra and Miki both sent legal letters threatening to sue High Hefner and Playboy for millions of dollars if the scandalous tapes were ever made public.

Meanwhile, Hef's former executive assistant Lisa Loving Barrett confirmed that the tapes were thrown into the sea.

"One of the video department leaders had a boat, and they put all of those video tapes in a barrel and took them to sea once they were removed from their cases." That was something I had cause to believe."

Unfortunately for them, Sondra, Hef's partner for five years in the late 1970s, does not think everything was discarded.

"Even then, I didn't imagine he wouldn't destroy them all." His ego would not allow him to trash all of those tapes."

Many women remained silent, fearful that the sex icon and his aides would leak any of the tapes or sexual images.
