The Vietnamese dam workers, hidden from the world, find solace in each other's arms. Their bodies, toned from labor, slip and slide against the cool concrete. One, her skin a warm brown, pins her lover against the wall, her fingers plunging deep. The other, her long hair cascading down, takes her lover's nipple into her mouth, sucking hard. They switch, their bodies intertwined, their moans echoing through the dam's structure. Their lovemaking intensifies, their bodies slapping against each other, their juices mingling. They climax together, their bodies shuddering, their cries swallowed by the dam's hum.
