The Thursday's episode of the top rated CBS sitcom "The Big Bang Theory" will feature Sheldon (Jim Parsons) having a nightmare where he saw Penny (Kaley Cuoco) and Leonard (Johnny Galecki) turning their bedroom into their own private sex dungeon.

To give fans a look at the making of the hot scene, Cuoco posted a picture in Instagram with Galecki.

"#bts of last nights @thebigbangtheory__ #kaleyspolaroids #corsettook15minstogeton @sanctionedjohnnygalecki," she captioned.

The 30-year-old actress is seen wearing a red corset, fishnet stockings and black shorts. Her outfit is accessorized with a black choker, military cap, and mesh gloves and a leather whip. Galecki, on the other hand, is only wearing a bondage-style outfit and leather briefs. He has a riding crop, too.

However, Mirror reported that "the upcoming 'Big Bang Theory' episode has been deemed 'too hot' for television." In connection, "advertisers have banned the dream sequence from appearing in the latest episode."

It was said that Penny's "boob-baring outfit became too much for advertisers to handle."

The real life ex-couple Kaley Cuoco and Johnny Galecki had their wedding during the Season 10 premiere.

Though the two have separate off-screen lives after they split in 2010, they still remain to be good friends.

Meanwhile, it was rumored that "The Big Bang" Season 11 is on the works and Johnny Galecki and Kaley Cuoco have no more role to play since they have decided to leave the series.

It has been speculated that the showrunners have changed the plot into something that eliminates the two of the highest paid actors, making sure that it will still remain on top and be the viewer's choice.

Moreover, some sources claimed the CBS network still continues to negotiate with Cuoco and Galecki to reprise their roles in the new Season. If not, there were rumors suggesting that the two will be replaced with new stars that are as good as Penny and Leonard.

It has been reported that in an Interview with Jimmy Kimmel, Kaley Cuoco hinted that Season 10 may be enough for her.

"10 is a lot of seasons," Kimmel said."Don't you feel like that's enough?"

"Yes," replied Cuoco. "Ten years, come on! All of my 20's. I went from like, hot, to like,30.I was 21 when I started this show."
