A harsh, unyielding grip clamps around the sub's hoden, making him gasp and wince. The dominant chuckles darkly, relishing the sub's discomfort, but his touch remains steady and controlled. He massages the delicate flesh, applying just the right amount of pressure to make the sub's breath hitch and his cock twitch. The sub's balls are manipulated, squeezed, and pulled, each movement drawing a new sound of pleasure-pain from his lips. The dominant's strong hands work in tandem, alternating between gentleness and firmness, keeping the sub on edge, his body a playground for the dominant's expert touch.
