The caravan's cramped interior echoes with the hum of the engine and the soft moans of its secret occupant. A man, his body tense, leans back against the worn leather seat, his pants undone, his dick hard and aching. His eyes are closed, his mind filled with vivid images, his hand moving rhythmically, pleasuring himself in the throes of a silent, kinky fantasy. The caravan bumps along the road, his body jerking with each movement, his breath coming in short gasps as he nears his release, his dick pulsing, ready to spill its load in the privacy of the moving caravan.
