'Masters Of Sex' Gets Even Sexier In Wild, New Trailer

We've all seen enough Justin Timberlake movies to know that "Friends with Benefits" just doesn't work.

Season 1 of "Masters of Sex" left off with William Masters (Michael Sheen), who is obviously a big JT fan, trying to explain that to Virginia Johnson (Lizzy Caplan), and the drama just snowballs (actually more like avalanches) into Season 2. The new trailer, first seen at The Hollywood Reporter, reveals fornicating with sisters-in-law, good old-fashioned fist fights and clandestine rendezvous leading to, what else, more fornicating.

Season 2 of "Masters of Sex" premieres July 13 at 10:00 p.m. ET on Showtime.
