‘The Big Bang Theory’ Star Kaley Cuoco Shares Sexy 'Red Room' Scene Photo

“The Big Bang Theory” Season 10, episode 7 had a scene where Penny (Kaley Cuoco) and Leonard (Johnny Galecki) transformed Sheldon’s (Jim Parsons) bedroom into a sex dungeon.

On her Instagram account, Cuoco shared a behind-the-scene photo from “The Veracity Elasticity.” Galecki is wearing a black leather attire in the snap, while Cuoco is wearing a skimpy black and red two-piece corset. The actress’ mouth is also wide open, as though to show off her sexy side. Cuoco revealed that she was the one who took the image using her Polaroid camera. “#bts of last night’s @thebigbangtheory…,” she wrote. The actress also included a hilarious hashtag that read, “#corsettook15minstogeton.”

In “The Veracity Elasticity,” Sheldon dreamt that his room was transformed into a sex dungeon the minute he decided to live with Amy (Mayim Bialik). After all, he had been contemplating whether or not transferring to Penny’s apartment and giving up his old room was the right thing to do.

Meanwhile, episode 7 also shed light on the importance of keeping someone else’s secret. Previously, Penny mistakenly told Bernadette’s (Melissa Rauch) colleague about the latter’s pregnancy. On Thursday night, it was Bernadette’s turn to spill Amy’s secret. Since moving in with Sheldon has been enjoyable, Amy decided to not tell her boyfriend that her apartment has already been fixed. However, Bernadette already knew about it and decided to tell Leonard and Penny.

During their conversations, Sheldon realized that Amy has been avoiding talks about her apartment. This has led him to speculate that Amy could be hiding something from him. While at Leonard and Sheldon’s apartment, Amy confronted Bernadette about telling Penny and Leonard the truth about her house. In the end, Amy came clean to Sheldon, and the couple still decided to live together.

“The Big Bang Theory” Season 10 airs Thursdays at 8 p.m. ET on CBS.
