Casandra "Cassie" Ventura is opening up about why she participated in the "Freak Offs" — hours-long sex parties where she alleges her former boyfriend Sean "Diddy" Combs forced her into sexual activities with other men.

Thursday's testimony and evidence was in contrast to the violence and shame Cassie said accompanied "hundreds" of her encounters with male sex workers that Sean "Diddy" Combs watched and controlled during their relationship.

For the first time, Casandra Ventura was questioned by Sean Combs’s defense lawyers, who confronted her with many messages from their relationship.

Combs faces five federal charges of racketeering, sex trafficking and transportation to engage in prostitution, to which he has pleaded not guilty.
