As the bus bumps along the road, so does the rhythm of her head, bobbing up and down on his stiff length. Her full tits press against his leg, her nipples hardening with excitement. She can feel his cock pulsing in her mouth, his pre-cum mixing with her saliva, creating a slick, warm mess. He tries to hold back, but the sight of her plump lips wrapped around his shaft, the vibrations of the bus, and the thrill of public exposure push him over the edge. He grips her hair tightly, his body tensing as he releases his load into her waiting mouth. She swallows every drop, licking her lips clean as she sits back up, a satisfied smirk on her face. The bus comes to a halt, and they step off, leaving behind a scene that's sure to leave the next passenger with an unexpected surprise.
