Extremely Dirty Movie To Rent Of The Week: Equation To An Unknown

The 1980 gay movie Equation To An Unknown isn't just a dirty movie, it's porn! This wild 'n out flick comes from the height of French gay erotica and follows the star Gianfranco Longhi as he hops around town on his motorcycle from one impassioned gay orgy to another.

This comes from the height of the Golden Age of Porn - a time when the lines between legitimate cinema and porn were blurred to the extent that some pornos premiered in theaters and received write-ups by mainstream critics. AKA our collective taste was simply elevated. USA Today writing up Winter Getaway Pt. 4 at Sean Cody? It's the America we deserve!

Anyway Equation To An Unknown artfully brings the passion and thrill of gay hookups to life throughout its one hour and forty-minute runtime. Yes Gianfranco Longhi leads, but as they say in the gay porn biz - it takes two to tango and perform oral and anal sex. He's joined by the jock Tony Weber - who tops Longhi in one of the hottest gay sex scenes here...

...Jean-Jacques Loupmon - who shows his legitimately breathtaking balls and big hard cock during a blowjob...

...and many many many more hot and horny French guys.
