What would you do if you found out your dad had written an erotic novel? Disown him? Barricade yourself in your flat? Or read it aloud on a weekly podcast to millions of people?

What would you do if you found out your dad had written an erotic novel? Disown him? Barricade yourself in your flat? Or read it aloud on a weekly podcast to millions of people?

That’s what Jamie Morton did. Recorded with friends James Cooper and Radio 1 DJ Alice Levine, My Dad Wrote a Porno documents a son’s scarring journey into his father’s exploration of his most, to put it delicately, intimate fantasies.

Written under the pseudonym Rocky Flintstone, the novel entitled Belinda Blinked follows the professional (and extremely unprofessional) development of newly appointed pots and pans sales executive Belinda Blumenthal.

Jamie, James and Alice’s weekly probe into the shockingly graphic world of the kitchen utensil business attracted the attention of listeners from the word go, amassing more than 10 million downloads to date.

The latest in a long run of sell out shows, an upcoming reading at the Union Chapel is offering a bonus chapter for audiences to cringe at, in celebration of the trio’s book release.

While Belinda Blinked (volumes one and two) is already available to download in all its leather-clad glory, the eponymous My Dad Wrote a Porno is filled with annotations, character profiles, quizzes and even the odd illustration - unsuitable for the prudish.

My Dad Wrote a Porno is at the Union Chapel on October 25 and the book is out on October 27.
