"Fuck me like you mean it," growls the straight porn star, his voice barely a whisper, yet it echoes in the quiet bus. His partner, equally turned on, grabs his cock, pushing it against his own, their sweat-slicked abs rubbing together. The driver, now openly jerking off, watches as the porn stars, overcome with lust, start a sloppy, passionate kiss, their hands exploring each other's bodies, their cocks rubbing together in a desperate search for release. The bus screeches to a halt, the door opening to reveal a group of surprised passengers, their eyes widening at the sight of the two porn stars, naked and rutting, and the driver, his cock out, encouraging the debauchery.
