Fifty Shades author EL James announces new 'mommy porn' entitled The Mister

The author of smash hit erotic fiction franchise Fifty Shades of Grey is at it again with a new release.

EL James appeared on the Today Show to announce The Mister, her all-new sex-filled story she reckons readers will "fall in love with".

Originally written as pornographic Twilight fan-fiction, the Fifty Shades series broke several literature sales records and spawned a trilogy of films that have grossed over US$1.3 billion.

James hopes The Mister is just as successful.

"I'm so excited to finally get this passionate new romance out into the world," James told the Today Show.

"It's a Cinderella story for the 21st century. Maxim and Alessia have led me on a fascinating journey and I hope that my readers will be swept away by their thrilling and sensual tale, just as I was while writing."

The "Maxim and Alessia" she refers to are the new Christian and Anastasia.

Maxim Trevelyan is a "privileged and aristocratic young Englishman", while Alessia Demachi is a "mysterious, talented and beautiful" woman who arrives in London "owning little more than a dangerous and troublesome past".

When asked by the Today Show if the new book included more of the mostly unmentionable material from the Fifty Shades novels, James replied: "Yes. Lots."

"It's not Fifty Shades erotic, because it's not Fifty Shades, but it is erotic," she added.

Filled with graphic descriptions of sex scenes and acts of BDSM, the Fifty Shades franchise's success is credited with popularising "mommy porn".

The Mister is set for release in April.
