‘PORN’ IS HYSTERICAL

HBO is trying to take not-at-all-sexy podcast global

To improve his pornography, Rocky Flintstone turned to Aaron Sorkin.

The retired Northern Irish builder with the Bedrock-inspired moniker became an unlikely erotica author, with a book that has titillated audiences in podcast form and is now set to take HBO.

Four years ago, Flintstone handed his son, Jamie Morton, a manuscript of his tawdry tome, “Belinda Blinked.” Morton and two friends, Alice Levine and James Cooper turned it into one of the most popular podcasts on the air: “My Dad Wrote a Porno.”

This weekend, HBO is bringing it to the world with an hour-long comedy special, a taping of a live reading of “The Lost Chapter.”

“It’s the best of the best of what we did live,” Levine told the Daily News.

“It’s a great introduction to everything that makes Rocky hilarious,” Cooper chimed in.

Nothing about “Belinda Blinked” is sexy. The few lines that are physically possible and are not unwanted descriptions of the day-to-day goings-on of a pots-and-pans company are cringy and uncomfortable.

“If I wasn’t here, I’d think my dad was a virgin,” Morton frequently deadpans about his publicity-shy dad, who hides behind his Rocky Flintstone pen name and took a writing course from Sorkin, the genius behind “The West Wing.”

But against all odds, the podcast and the ensuing HBO special are hilarious, to the credit of the threesome, who push through the awkwardness — and sometimes lean into it — and find the humor in truly bad sex.

“The free porn brings you in but you stay because there are a few universals: three friends sitting around shooting the s--t, trying to make each other laugh, embarrassing dads and the fact that we just don’t want to think about our parents being sexual,” Levine told The News.

The HBO special finds the eponymous Belinda taking her sales team to a group bonding session that quickly turns sexual, but still not sexy. Levine, through various shades of red, regales his fans with corporate reunions and the world’s most confusing dice game. Levine provides a medical demonstration of exactly why none of this actually works.

They make a drinking game out of Rocky’s terrible grammar, the random semicolons and run-on sentences in particular. And the audience members, most of who are familiar with the naughty novel, treat the podcasters like family.

“Everyone feels a real investment in the show,” Morton told The News.

With HBO, “My Dad Wrote a Porno” looks to go global; the three called themselves “Belinda evangelists.” It’s a hard sell, asking people to watch three strangers read porn, and bad porn at that, out loud. But the podcast already has more than 150 million downloads.

Morton’s mum on what comes next, although rumors of a “Belinda” movie have long been whispered. Podcast guests, including Daisy Ridley, Michael Sheen, Emma Thompson, Elijah Wood and Hayley Atwell, have all called dibs on various roles if and when the time comes.

For now, they’re just looking ahead to the fifth season of the podcast, which is tentatively set for later this year. It’ll be Rocky’s first writing since the podcast debuted, but no one is quite sure what, if any, takeaways he possibly could have gotten from the fan reaction.

He did pay for Sorkin’s MasterClass though, to learn from the best.

“Dad, you can barely write dialogue,” Morton told him, “let alone walk-and-talks.”

“My Dad Wrote a Porno” premieres Saturday at 10 p.m. on HBO and will be available for streaming and on demand.
