R&B singer Cassie was pressed to read aloud her own explicit messages to ex-boyfriend Sean “Diddy” Combs in federal court Thursday, including texts that showed her expressing desire for the drug-fueled group sex she previously testified left her traumatized. Lawyers for Combs sought to portray Cassie to the jury as a willing and eager participant in the music mogul's sexual lifestyle. Combs has pleaded not guilty to federal sex trafficking and racketeering charges. His defense says that, while he could be violent, nothing he did amounted to a criminal enterprise. Prosecutors say he exploited his status as a powerful music executive to violently force Cassie and other women into these marathon encounters with sex workers, called “freak-offs,” which sometimes lasted days. Combs insists all the sex was consensual. He's also accused of using his entourage and employees to facilitate illegal activities, including prostitution-related transportation and coercion, which is a key element of the federal charges. Messages between Combs and Cassie — both romantic and lurid — were the focus of the fourth day of testimony in a Manhattan courtroom. Defense attorney Anna Estevao read what Combs wrote, while Cassie recited her own messages about what she wanted to do during the freak-offs. Cassie’s testimony will resume Friday. Combs, 55, has been jailed since September. He faces at least 15 years in prison if convicted. Defense highlights Cassie's messages to Combs While Cassie, whose legal name is Casandra Ventura, has said she felt compelled to participate in freak-offs to keep Combs happy, Estevao pointed to message exchanges where Cassie appeared excited about the sexual encounters and raised the idea of having one on her own. In August 2009, Combs asked when she wanted the next encounter to be, and she replied “I’m always ready to freak off.” Two days later, Cassie sent an explicit message and he replied in eager anticipation. She responded: “Me Too, I just want it to be uncontrollable.” Later that year, however, she also sent Combs messages that she was frustrated with the state of their relationship and needed something more from him than sex. Estevao also noted a July 2013 text message exchange where Cassie wrote to Combs, “Wish we could've FO'd before you left,” using the initials of freak-off. In a 2017 text message, Cassie told Combs: “I love our FOs when we both want it." On the stand Thursday, Cassie explained: “I would say loving FOs were just words at that point.”
