London's adult work district, a labyrinth of narrow streets and hidden alleyways, thrums with life under the cloak of night. The rain falls in a steady patter, dampening the sounds of the city's debauchery. Inside, the air is thick with the scent of sweat and sex, as bodies writhe and grind in the dim, pulsing light. Outside, the rain continues to fall, washing away the sins of the city, only to be replaced by new ones as the night wears on.
