The man, a picture of concentration, grips his rigid dick, veins bulging like river deltas. His hand moves with practiced ease, from base to tip, coaxing out every ounce of pleasure. His other hand cups his balls, rolling them gently, adding another layer of sensation. His breath comes in ragged gasps, his body tensing as he approaches the precipice. With a guttural moan, he tips over the edge, his cock pulsing as he paints the room with thick, creamy streams of cum.
