Casandra Ventura, the singer and model known as Cassie, told a jury in Manhattan on Wednesday that her life with Sean Combs had its moments, but was largely filled with beatings, threatened blackmail and even a rape.

During more than five hours of testimony in Mr. Combs’s sex trafficking and racketeering trial, Ms. Ventura recounted how he had stomped on her in the back of his car and how she suffered a gash above her eye when he threw her against a bed frame. She also recounted how, after the pair had dinner in 2018, Mr. Combs raped her in her living room.

. Ms. Ventura told the court she stayed with Mr. Combs despite beatings and other abuse partly because of the nagging, persistent fear that videos of their sexual encounters with male prostitutes, the hundreds of “freak-offs” that she said Mr. Combs enjoyed watching and recording, would be posted online. Hers was not idle anxiety based on what she viewed Mr. Combs might be capable of, she said, but the consequence of repeated threats he had made to use the material to damage her if she deviated from his wishes. In one case, she described sitting beside him on a flight when he displayed for her videos that she thought had been destroyed.
