Unnoticed by the world, a man delves into the private practice of kegel exercises, his penis the center of his intense, personal training. He starts with subtle clenches, feeling the muscles tighten around his root, the sensation traveling up his shaft. His dick begins to swell, his hand wrapping around the growing length. He pumps slowly, feeling every ridge and vein as he pushes his body further. Sweat beads on his forehead, his breath coming in ragged gasps, his solo session a raw, intimate exploration of his body's capabilities.
