The dimly lit trailer hums with tension as the redneck step-daddy takes a seat on the filthy toilet, his son standing by, ready to serve. The step-dad, a burly, tattooed brute, grunts as he releases a steady stream into the cup, his son's eyes never leaving the precious liquid. The younger one, a scrawny, hungry thing, takes the cup, sniffing it before swallowing the piss in greedy gulps, his dick hard and tenting his jeans. The step-dad, amused and turned on, watches, his own cock twitching at the sight of his son's debauched thirst.
