In the shadows, an unseen hand begins a solo symphony of touch. It starts innocently enough, a gentle caress along a muscular thigh, but soon, it's a hungry exploration, tracing the lines of a body honed by years of discipline. The hand wraps around a thick, hardening cock, stroking it to full length, the skin smooth and hot to the touch. The soloist's breath hitches, his hips bucking as he fucks into his own fist, the room echoing with his pleasure, his body tensing as he nears his peak, before finally, he comes undone, his cock pulsing as he paints his chest with his release.
