In the dimly lit tunnel of a desolate metro station, a mysterious figure approaches a lone woman waiting on the platform. She's dressed in a revealing outfit, her heels clicking on the cold concrete. He's clad in a hoodie, face obscured. They exchange no words, just a nod. She turns, bends over slightly, and he's on her, pulling up her skirt, revealing her ass and the thin string of her thong. He runs his gloved hands over her curves, then slips one into her panties, finding her wet and ready. She gasps, gripping the edge of the platform as he unzips his pants and pushes into her from behind. The train rumbles in the distance, its headlights illuminating their anonymous fuck in fleeting bursts.
