The intense arousal begins with a throbbing red cock, already leaking pre-cum. The unseen hand, lubed and eager, strokes the veined shaft with rhythmic precision. The balls, heavy and full, tighten as the moment nears. The man's grunts fill the room, echoing the primal dance of pleasure. With a final, desperate tug, the cock pulses, spewing hot, creamy cum onto the waiting, eager palm.
