She's a streetwalker, he's a john with a fetish for the unknown. In the dimly lit metro station, they lock eyes, a silent agreement passing between them. She leads him to her usual spot, a secluded corner where she services clients for cold, hard cash. He's eager, his cock already hard in his pants. She undoes her pants, revealing her bare, glistening pussy, and begins to stroke him, whispering her price. He agrees, and she slips him inside her, riding him hard and fast, her moans echoing through the empty station.
