In the heart of the city, a bus ride becomes an unexpected peep show. A young blonde, dressed in a revealing sales uniform, propositions riders for a blowjob. She straddles a lap, her tight skirt riding up to reveal her thong. She works the cock with skill, her head bobbing up and down, eyes locked on the passenger's. The bus lurches, her body grinding against him. She's a whore, paid for her services, but the thrill of public exposure is evident in her eager, sloppy performance.
