It’s safe to say you’ve probably never heard Fifty Shades of Grey like this.

“Fifty Shades of Grey” star Jamie Dornan and Jimmy Fallon took turns reading lines from the E.L. James books in random accents on Monday. And if you thought Anastasia Steele and Christian Grey sounded raunchy, just wait until you hear Fallon saying “chocolate hot fudge brownie sex” with a Russian twist. The movie comes out this Valentine’s weekend, but in the meantime this video will definitely leave you as a “quivering mass of raging female hormones.”

“The Tonight Show Starring Jimmy Fallon” airs weeknights at 11:35 p.m. ET on NBC.
