There's a rule that if it exists, there is a porn version of it -- yet one of the hit HBO series 'Girls' hardly seems necessary, given the show's frank portrayal of sex. But here we are.

According to XBiz (a NSFW porn news site -- because of course this exists), porn mega-company Hustler has just completed filming on their porn parody version of Lena Dunham's HBO series 'Girls.'

The "film" is titled 'This Ain't Girls XXX,' since they have to make sure you know that this isn't really 'Girls,' but it's also porn and is based on 'Girls,' though the only similarities are character names and quirky dalliances with cake because that one time Lena Dunham's character Hannah had a cupcake in the bathroom.

Porn actor Richie Calhoun plays Hannah's weird boyfriend Adam in the parody and promises, "I tried to make it as weird as possible. I tried to say really weird things and do really weird positions." So, you know, he was trying to be really weird because the biggest takeaway from 'Girls' is that everyone is quirky and weird. Weird. Let's say it one more time.

Playing the role of Hannah is Alex Chance, and the porn's story (yes, it has one of those) follows her as she decides to give up on men (something Hannah would never do because this ain't 'Sex and the City' -- wait, is that a porn parody Hustler made too?) and experiment with lesbianism, which sounds like something your mom would half-jokingly declare after her third divorce.
