Karissa Shannon says a disturbing claim from Hugh Hefner's widow is true and that the late Playboy founder tried to pressure her and her twin sister during their years at the mansion.

In fresh remarks she said Hefner pushed her and twin Kristina toward incestuous acts with each other. She said the twins stayed at the Playboy mansion between ages 18 and 20.

"He would try and force me and my sister to have sex with each other," she said. She stressed they "never" actually did so and instead had to fake it. "We faked it every time. And it was horrible," she said.

Response to Crystal Hefner

She spoke after Crystal Hefner publicly described the founder forcing the twins' heads toward one another. Karissa said Crystal was often present for those moments.

Karissa said Crystal knew the act was fake while Hefner did not. She said he wanted to watch them fool around together and claimed that loving each other meant doing it as a pair.

Earlier series remarks

Karissa previously described joint sexual encounters with Hefner in the 2022 series "Secrets of Playboy," calling every encounter an "assault" and saying it felt "like rape."
