Here’s a story about consent from this year’s Burning Man:

One afternoon I was hanging around camp, watching the passerbys strolling and biking down the street (between Basra and Cinnamon, on 7:00). There was a woman from a BDSM camp who was standing in the middle of the street, offering to administer spankings with a rather fierce-looking paddle. One passing woman stopped, bent over and offered her bottom in an especially fetching fashion.

The woman with the paddle leaned towards her and said, “That’s not enough. I need to hear a ‘yes’.”
