Masters of Sex
Catch “Masters Of Sex” Season 4, episode 4 on Sunday, Oct. 2 at 10 p.m. EDT on Showtime. Showtime

Showtime’s “Masters Of Sex” is now depicting the era of the swinging ‘60s and ‘70s in Season 4. Dr. William “Bill” Masters and Virginia “Gini” Johnson facilitated the sexual revolution with their book, “Human Sexual Response.”

Episode 3 showed Bill (Michael Sheen) discovering the fact that Virginia (Lizzy Caplan) never got married to Dan Logan (Josh Charles). Meanwhile, the sex researchers also found out that their professional partners Art (Jeremy Strong) and Nancy (Betty Gilpin) are married.

What will happen in episode 4? According to the official synopsis on Showtime, Art and Nancy will throw a party. But it isn’t just any kind of party. A preview of “Coats Or Keys” reveals that the party involves gentlemen picking a lady’s coat from those who are attending the party. The one whose coats he picks will end up spending time with him alone. It seems like a sexual party of some sort.

Of course, Libby (Caitlin Fitzgerald), Bill, Virginia, Bill’s attorney Keller (David Walton), Betty (Annaleigh Ashford) and Lester (Kevin Christy) wind up at the party. From the looks of the preview, it seems like Art picks Virginia’s coat. Will they have sex?

The party will be the main focus on “Masters Of Sex” Season 4, episode 4. As the night goes on, pairings and perspectives will shift. The synopsis talks of the day exposing the consequences of the evening. What will happen at that party?

Another video shows Libby meeting Heller. He is surprised to see her since he never expected her to be at a party like this.

Some time during the night, Bill gets Libby’s coat. She orders him to do something for the sole purpose of her pleasure. This will be interesting!

However, the most interesting part of the night will be Virginia, Nancy and Libby being introduced to a friend of Dan Logan’s named Mike Schafer. In fact, Mike tells Virginia that her “husband” told her they will have dinner together next week. She is almost caught lying that she is Dan’s wife when Mike tells her that Dan insisted on having a meal cooked by his wife. Everyone knows Virginia is a terrible cook.

“Masters Of Sex” Season 4, episode 4 airs Sunday, Oct. 2, at 10 p.m. EDT on Showtime.
