A strapping, middle-aged Japanese husband, clad in a snug, low-rise boxer, takes center stage in this explicit solo performance. He starts by gently caressing his bulge, the fabric tenting with his growing arousal. With a mischievous glint in his eye, he grabs a bottle of lubricant, squirting the slippery liquid onto his briefs. The fabric clings to his hard cock, outlining every vein and contour. He grinds against his hand, the fabric rubbing against his sensitive flesh, teasing himself. With a sudden tug, he tears the underwear, freeing his engorged cock. He strokes it expertly, his other hand fondling his heavy balls. His breathing grows ragged as he edges closer to climax, only to pause and start again, prolonging his pleasure. Finally, with a guttural moan, he strokes himself to a powerful orgasm, ropes of cum shooting onto his stomach and chest.
