A man's fingers dance along the length of his rigid shaft, his grip firm and steady. He knows every contour, every vein, every sensitive spot that drives him wild. His other hand cups his heavy balls, rolling them gently, sending waves of pleasure coursing through him. His body rocks, his hips bucking as he chases his release. The tension builds, his muscles taut, his breath ragged. With a final, guttural groan, he spills his load, his cum coating his hand and dripping down onto the floor below.
