As part of the promotion for the second season of Showtime's "Master of Sex," ten pairs of strangers agreed to undress each other while in bed.

Meeting for the very first time, the ten pairs of various sexual orientations and ethnic backgrounds were filmed taking each other's clothes off, New York Daily News reported.

In the black and white video by Tatia Pilieva entitled "Undress Me," some of the pairs are seen kissing each other after getting to know each other and started stripping.

The experiment was inspired by a research conducted by Dr. William Masters and Virginia Johnson in 1957 using 20 complete strangers undressing each other.

Returning on its second season on July 13, Sunday, "Master of Sex" tells the story of Masters and Johnson, the pioneers of human sexual research from the 1950s to the 1990s. The characters are played by Michael Sheen and Lizzy Caplan, according to Metro.

The story of "Master of Sex" revolves around the brilliant scientist and bold pioneer Masters and his self-taught junior partner and former mistress Johnson. It takes place during the time when women were struggling before the rise of feminism.

"Master of Sex" features an era when men were in charge, Ivy League colleges and social clubs were exclusively for men, abortion was illegal, and it was rare to have women in science and medicine, according to New York Times.

Graphically depicting some of the bodily pleasures, "Master of Sex" also shows some scenes of sex and masturbation.

Other important characters in the series are played by Julianne Nicholson and Caitlin Fitzgerald.

While in a twisted, passionate relationship with her boss and research partner Masters, Johnson collaborates with another boss Dr. Lillian DePaul, an OB-GYN who keeps her cancer as a secret, played by Nicholson.

Another important character played by Fitzgerald is Johnson's submissive wife Libby, who is isolated at home taking care of their new baby.
