The women detailed the Jewish actor's behavior in a Los Angeles Times article published Thursday.
Another woman, Katie Ryan, alleged that Franco manipulated his students into doing what he wanted by making "everybody think there were possible roles on the table if we were to perform sexual acts or take off our shirts".
Franco opened two Studio 4 schools in Los Angeles and NY in 2014 before abruptly closing in October 2017.
One woman, Violet Pavey, who claims to have once had a consensual relationship with Franco, alleges that he once forced her into an oral sex act when they were in his auto. They surfaced on Twitter minutes after he accepted a best comedy actor Golden Globe on Sunday for his role in The Disaster Artist. Tither-Kaplan, who took acting lessons from Franco, believes that it was an abuse of power and thought that his use of the Time's Up pin was a "slap in the face".
Some of the women say that Franco encouraged them to take off their clothes while performing sex scenes and would get mad if nobody volunteered.
Tither-Kaplan also alleged that Franco had removed vaginal guards while filming oral sex scenes, which the Times confirmed with another actress present.
Franco also addressed a vague and now-deleted tweet from Ally Sheedy, who he directed in a 2014 Broadway play. You were wearing a time's up button like a lot of guys at the show and some women during your time on stage said that was hypocritical, they went to Twitter and said that it was hypocritical based on their experiences that they have had with you.
Paley said she met The Disaster Artist star in 2016 and was having a romantic relationship with him when he pressured her into performing oral sex on him while sitting in her auto.
"There were some things on Twitter, I havent read them".
During his Wednesday night appearance on Late Night, host Seth Meyers asked why he hadn't contacted Sheedy about her tweets after denying he engaged in any questionable behaviour with her. Franco said, "It was so shocking". The pin, which said Time's Up, was a nod to the movement started in December by powerful women in Hollywood. I think the point of this whole thing is that we listen.
Franco, as a teacher and mentor, had a position of power with several of the women, one of whom described an environment where saying no to Franco could get them sent home from the set of a movie.
