Cassie Ventura reveals how Diddy’s twisted ‘freak-offs’ began— and how young she was at time

Cassie Ventura revealed excruciating details Tuesday about Sean “Diddy” Combs’ twisted “freak-off’’ sex sessions, including how they began in the first year of their relationship when she was just 22.

“Sean proposed to me this idea, this sexual encounter her called voyeurism, where he would watch me… [have] sexual activity with another person, specifically another man,’’ the singer told the jury at Combs’ sex-trafficking trial in Manhattan federal court.

“I just remember my stomach falling to my butt,” said Ventura, now 38, married to Combs’ former personal trainer and eight months pregnant with her third child.

“Just the nervousness and confusion in that moment. … I didn’t have a concept how that would be a turn-on. but I felt a sense of responsibility since he was sharing something like that with me. I was confused, nervous, but I also loved him very much, and I wanted to make him happy.”

Venture described how one of the typical sex sessions would involve “the hiring of an escort and setting up this experience so that I could perform for Sean.

“It just involved watching Sean be able to watch me with the other person and actually direct, direct us with what we were doing,” she said.

Ventura said she didn’t know how the now-infamous term came about.

But “pretty quickly over time, I knew it wasn’t something I wanted to be doing, especially as regularly as it became,” she said.

“Eventually it became a job for me pretty much. … It was something he would want to do. I would have the contact to set it up. … But in the beginning, Sean set it up. He set it up.

“But again I was in love, and I just wanted to make him happy.”
