In the hushed, sweat-scented air of the late-night gym, a solitary bodybuilder revels in his temple of flesh. Every curve and contour of his chiseled form is a testament to his devotion, a masterpiece honed by endless hours of toil. As he admires his reflection in the mirror, his hand traces the hard lines of his abs, traveling lower to cup his heavy, throbbing cock. With a soft curse, he begins to stroke, his grip tight and rhythmic. His other hand kneads his heavy balls, rolling them gently as he picks up pace, his breath coming in ragged gasps. The sound of his fist sliding up and down his slick cock fills the room, a symphony of solo pleasure.
