Melissa Rauch is ditching her nerd glasses and conservative attire for a sexy S&M-inspired photo shoot with Maxim.

The Big Bang Theory actress amped up the sex appeal in the lingerie-clad spread and definitely seemed confident rocking a beaded corset.

"I've actually never been! However, I am similar to Bernadette in that we both spent some time waiting tables," she told the magazine.
