Lost in the sprawling metro system, a hooded figure seeks solace in the shadows, their eyes scanning the platforms for an unsuspecting victim. Spotting a lone woman, they approach, their heart pounding in their chest. Pressing against her from behind, they feel her tense, then relax as their hands roam her body. She's wearing a short skirt, easy access for the stranger's eager hands. They rub her pussy roughly, feeling the heat and wetness through the fabric. She grinds back, encouraging more. The stranger unzips, their hard cock throbbing, ready to claim this unknown prize in the city's dark underbelly.
