Kaley Cuoco, Johnny Galecki

Oh, you've never pictured what Penny and Leonard would look like all dressed up in bondage gear? That's weird.

Well, you're about to get a great visual that will be burned into your brain for the rest of time, so there's that! Actress Kaley Cuoco shared an unforgettable snapshot of herself and co-star Johnny Galecki all strapped up in leather and sin after shooting a sexy scene for Big Bang Theory.

"#bts of last nights @thebigbangtheory__ #kaleyspolaroids #corsettook15minstogeton @sanctionedjohnnygalecki," Kaley wrote with the photo on Instagram.

The photo shows Penny (Cuoco) rocking some black fishnets, a choker, hat and corset while holding a whip next to Leonard (Galecki), who looks like he's not sure what's going on while wearing some leather bondage couture (we're assuming).

The pair are supposed to be in a sex dungeon during one of Sheldon's (Jim Parsons) nightmares, LOL.

Fans of the show were worried over the summer that they may be nearing the end of the series.

Big Bang Theory was renewed through season 10, the current season, with the cast only signed on until then.

"We are very confident that everyone involved wants more Big Bang past year 10 and I know Warner Bros. will make those deals," CBS boss Glenn Geller told reporters at the 2016 TCA Summer Press Tour.

In a smaller pool of reporters, Geller said there is now time table for when an announcement about the show's future would be made. "We'll put it on for as long as everyone wants Big Bang on the air," he said. "I hope it lasts forever."

The feeling is mutual.
