Porn without the sex? Hollywood’s latest installment of original content relies on story lines rather than sex to get audiences excited.

According to Reuters, It started when three brothers joked about making pornography for fans of the genre who happen to be offended by on-screen sex. Out of that joke came an idea for a website, and they called it “PG Porn.”

In creating pornography that appeals to viewers who want their titillation toned down, brothers James, Sean and Brian Gunn are banking on web-surfers’ growing acceptance of porn.

Sean starred in the television show “Gilmore Girls” and James wrote the screenplay for the 2002 movie “Scooby-Doo.” Their latest production, a short spoof called “Nailing Your Wife,” premiered on Wednesday at their site.

With pornography all over the Internet and the video store, the Gunn brothers rely on viewers’ familiarity with all its conventions — the goofy acting, the bad music, the lace-thin plots — to create movies that look like the real thing but skirt nudity. Comedy substitutes for hard-core sex.

The actor in “Nailing Your Wife” is Nathan Fillion, who appeared in the ABC show “Desperate Housewives,” and his castmate is porn star Aria Giovanni. PG Porn will feature similar pairings in the future.
