In the throes of self-love, a thick, uncut cock bobs and weaves, its owner's skilled hand working its length. The weight of his balls swings gently, a pendulum of pleasure. He cups them, feeling their fullness, before returning to his cock, now slick with spit and pre-cum. His breath hitches, his body tensing as he nears the edge. With a final, firm stroke, he spills his seed, a testament to his solo prowess.
