The private room is filled with the soft hum of the piercing gun and the occasional moan of the solo client. His hands explore his body, the metallic balls of his piercings clinking against each other as he strokes his cock, the sensations intensified by the cool metal against his heated flesh. The coconut oil slick on his skin glistens under the soft lighting, his body a symphony of pleasure as he plays with his piercing, unable to stop the relentless pursuit of his own satisfaction.
