Diddy‘s trial finished up its 21st day of testimony … with the mogul’s ex returning to the stand to talk more about their relationship — and how she used the prospect of freak-offs to persuade him.

The rapper was back in court in Manhattan Wednesday, where “Jane” — the pseudonym his ex-girlfriend is using to testify against him — was asked questions by Diddy’s defense about loving texts she sent to Diddy after freak-offs.

In one, she told him she had so much fun … adding that her love was “unconditional” and “for life.”

Jane also admitted to buying shorts for Diddy and a male escort to wear during freak-offs as well as “Rhino Pills” … a sexual enhancement for men usually sold at gas stations.

In one of the more interesting pieces of testimony, Jane admitted she used the possibility of having a freak-off to get Diddy to leave a vacation early and spend time with her instead of Yung Miami.
