Masters of Sex, a Showtime series with sex in the title. Enough said. The eminently lust-worthy Lizzy Caplan returns to the boob tube after a much too long hiatus to play real life sex pioneer Virginia Johnson. As part of the human sexuality research team Masters & Johnson, she’ll be teaming up with Michael Sheen to delve deep into the world of sex drives. There’s plenty of hard research to pound out, and Lizzy gets naked in the first episode alongside blonde babes Helene Yorke and Annaleigh Ashford. Lizzy shows off her bodacious boobies left and right in this series, not to mention her amazing ass! Supporting actress Allison Janney shows off her terrific tits for a couple hot sex scenes. Annaleigh Ashford shows off her mesmerizing mams several times and even lezzes out with a topless Sarah Silverman! There’s almost too much delicious nudity in this series to count but we see bares boobs from Alycen Mlaone, Hanna Hall, Kristen hager, Erin Cummings, Olivia Alaina May, Nicole Steinwedell, Nicholle Tom, Kristin Slaysman, Ellen Wroe, Charlotte Chanler, Rose McIver, Sarah Allyn Bauer, Cheryl Briker, Betsy Brandt, Jessica Howell, and Veronica Mannion, just to name a few! With action like that afoot, you’ll be putting Masters together with Johnson too!
