With a sigh, he lets his uncut cock flop out, already knowing the task at hand. The cock rings, innocent-looking yet powerful, lie on the bed beside him. He starts with a thin, silver one, stretching his soft flesh over it, feeling the subtle pressure. As he strokes, his cock responds, growing harder, the ring biting into his flesh. He switches to a thicker, black one, hissing at the intense sensation. His cock twitches, eager, as he pushes through the discomfort, his balls tightening, ready for the final, most challenging ring.
