The metro's dim lights cast long shadows, hiding the secret encounter unfolding. The stranger's rough touch elicits a shiver, his fingers expertly teasing her clit, making her clench around them. She bites her lip, suppressing a moan, as she strokes his hardening cock through his pants. The train jerks to a halt, forcing them apart, but their game of cat and mouse continues, their desire undeterred by the city's ever-watchful eyes.
