After a steamy run, he eagerly plunges his throbbing member into his sweaty underwear, relishing the friction until he blows his load. This filthy undies finish is a treat for all.

After a long day of hard work, he couldn't resist the urge to indulge in some personal pleasure. He found himself in front of the mirror, his hands already exploring the bulge in his trousers. The excitement was too much to handle, and he began to breathe heavily, his breath caressing the fabric of his underwear. His grip tightened, his movements becoming more erratic as he neared the edge. The anticipation was palpable, his body trembling with the impending release. With a final, desperate stroke, he unleashed his pent-up desire, his hot load staining his underwear. The sight of his cum staining his underwear was enough to drive him even wilder, his breath now a hot breath on the dirty underwear. He was left panting, his release having been even more intense than he had anticipated. The satisfaction of his release left him weak in the knees, his underwear now a testament to his pleasure.
