Sean “Diddy” Combs’ ex-girlfriend, Cassie Ventura, began what could be a days-long testimony in Combs’ sex trafficking trial Tuesday, alleging on the witness stand Combs had subjected her to physical abuse and coerced her to participate in “freak off” sex performances. (Here is a complete list of the allegations against Combs).

Combs faces five criminal counts: one count of racketeering conspiracy; two counts of sex trafficking by force, fraud or coercion; and two counts of transportation to engage in prostitution.

During her first day of testimony Tuesday at Combs’ sex trafficking trial, Cassie described being pressured into degrading sexual encounters with paid sex workers.
