Fan favorite couple, Penny and Leonard, got naughty on Thursday's episode of "The Big Bang Theory." On Instagram, series star Kaley Cuoco shared a NSFW behind-the-scenes photo to their fans which sees the duo wearing raunchy outfits.

Fans of "The Big Bang Theory" were treated to a shocking and hilarious moment during the hit comedy's latest outing (aired Nov. 3). During the half-hour episode, viewers were offered a look into Sheldon's nightmare where he saw his friends, Penny and Leonard, dressed in costumes inspired by "Fifty Shades of Grey."

While the scene was only written for a dream sequence, Penny and Leonard's naughty sex explorations was able to garner huge amounts of laughs from the live audience. Penny's portrayer later shared a closer look into the fan favorite couple's S&M moment on Instagram. The behind-the-scenes image sees Cuoco with co-star Johnny Galecki sporting their sexually explicit outfits, complete with bondage gears, corset, fishnet stockings and more.

"#bts of last nights @thebigbangtheory," the actress wrote in the caption - while also sharing that the corset took 15 minutes to "get on."

Next Thursday's episode of "The Big Bang Theory," meanwhile, promises to deliver another laugh out loud episode. As revealed in the plot synopsis, the Nov. 10th installment will find Sheldon convincing Amy to have a baby. Elsewhere, viewers will find Raj embarrassed about his new date's occupation.

Created and executive produced by Chuck Lorre, "The Big Bang Theory" also stars Jim Parsons, Simon Helberg, Mayim Bialik, Melissa Rauch and Kunal Nayyar. Season 10 airs every Thursday at 8Pm on CBS.
