Money changes hands, a silent agreement between strangers. Clothes come off, inhibitions shed like old skin. The bus rocks with the rhythm of their fucking, the driver oblivious or uncaring. Cock after cock slides into eager, bare ass, the slapping of flesh against flesh a symphony of carnal desire. Cum drips from used holes and satisfied mouths, a testament to their public debauchery, as they exit, sated and ready for the next ride.
