Up Your Alley, the dirty little brother to the Folsom Street Fair was packed with hot and hunky leathermen. And yes there was nudity and hard dicks. The Steamworks Naked Twister didn’t disappoint either.  The MC was making sure that the game lived up to its name as all the contestants got naked and into some very compromising positions.  When the sun came out, the medical stations were popular as they were giving out free sunscreen and in some cases, the cute EMTs were helping apply it. Hot indeed! More photos from the day follow here.  (NSFW)
