In the heart of the woods, Humping Jack, our exhibitionist exhibitionist, finds an abandoned tree trunk and decides to make it his outdoor masturbation station. Naked, he straddles the rough, earthy log, his ass cheeks rubbing against the bark as he grinds his hips in a primal rhythm. His thick cock bounces with each thrust, pre-cum glistening at the tip. He strokes himself, the forest canopy above offering dappled sunlight, as he jerks off enthusiastically. His groans echo through the trees, only nature's creatures as his audience, until he reaches his climax, his cum splattering onto the fallen trunk.
