In the dim light, a substantial hand begins its slow, sensual dance around a rigid, engorged shaft. The hand, large and strong, grips the cock firmly, its thumb brushing against the sensitive underside with each upward stroke. The cock twitches, eager and hungry, as the hand expertly works its way towards the climax. The pace quickens, the grip tightens, and the hand, slick with pre-cum, brings the cock to its explosive end.
