Sadists and masochists came together to celebrate at San Francisco’s annual Folsom Street Fair on Sunday, September 28th.

The fair began in 1984 primarily as a leather event for San Francisco’s gay community, but has since grown to become one of the world’s largest fetish events. This past Sunday, the fair celebrated its 25th anniversary, attracting crowds of sparsely clothed men and women, as well as those decked out in lascivious costumes of leather, latex, corsets, and rope.
