Rob Quin, a mountain of a man, commands his step son, Muscled Madison, to trim his overgrown balls. Madison, a nimble twink, approaches warily, taking in the sight of his step dad's huge, hairy nuts. He begins the task, his small hands trembling slightly as they cup and tug at the heavy flesh. Quin's cock throbs, straining against his briefs, as Madison's fingers brush against it. The twink can't resist, leaning in to lick the pre-cum beading at the tip. Quin groans, his big hand gripping Madison's head, pushing him down, encouraging him to take more of his thick, vein-ridden cock. Madison eagerly obliges, eager to please his step daddy.
