Yesterday on Dore Alley, loads of gay men (and a smattering of women) converged for the annual Dore Alley (aka Up Your Alley) Fair, SOMA's other sex fetish fair. Similar to Folsom Street Fair but grimier and more intimate, folks showed up sporting leather gear, animal attire, bare butts, straitjackets, and more. Here are some SFW pics from the slap-and-tickle festivities. Enjoy.

Also, local activist and blogger Michael Petrelis showed up to the festivities and took these shots. Check them out too!
