The jock's big balls tighten as he nears climax, his breath ragged, eyes locked onto his throbbing cockhead. He strokes faster, his grip firm, fingers tracing the vein along his shaft. The open air teases his sensitive skin, adding to the intensity. With a final groan, he erupts, thick ropes of cum painting the jacuzzi water, his body twitching as he milks every last drop from his heavy ballsack.
