With Virginia Johnson and Bill Masters getting closer than ever on Season 2 of Masters of Sex, will a new character get in between them?

Sexual Revolution Explodes Between Virginia And Bill

According to Variety, actress Erin Cummings has just been cast in a new role on the Showtime drama. Cummings will be playing Kitty, a high class prostitute. Kitty reportedly has a no nonsense attitude, who is smart and calculating, but also "care-taking." Kitty is also an important part of the Season 2 research by Virginia and Bill.

Virginia and Bill were moving into a new phase of their relationship when Season 1 left off. Bill was declaring his love for Virginia and it seemed like the two were going to be embarking on a full-blown affair. "We could have an affair," Virginia tells Bill in the teaser trailer, "but what we have is so much more. We have the work."

Courtney Vance And More Gear Up For Season 2 Of Masters Of Sex

Showrunner Michelle Ashford recently said she struggles to find the balance of Masters of Sex between story and sex. "Our challenge has always been, how do you make sex story? That's what we're trying to do. As long as I feel we're trying to make sex story, we'll try anything. Then I don't feel creeped out by it."

Sarah Silverman also was announced as part of Season 2 as a guest star, along with actor Courtney Vance.

Masters of Sex returns to Showtime on July 13 at 10 p.m. ET.
