Nearly 15,000 fellow leather men and fetish enthusiasts turned out for this year's Up Your Alley® in San Francisco. Leather daddies ruled the streets of San Francisco’s South of Market district. They were joined by skinheads, punks, bears, pigs, and other BDSM devotees who engaged in public spankings, whippings, floggings, bondage, domination and submission, creative water sports, and so much more.
