Amber Michaels, the subway's most wanted, prowls the platforms, her eyes scanning the crowd for the next target. She spots a well-dressed businessman, his eyes lingering on her cleavage. He's her mark. She leads him to an isolated car, her hips swaying, her hands already unbuttoning her blouse. She pushes him against the door, her mouth hungry on his, her hand reaching for his belt. The train lurches, the doors slamming shut, enclosing them in their private, steamy world.
