In the dimly lit room, Curmudgeon691, a man of experience and taste, indulges in another solo session. His calloused hands, a map of years spent exploring his body, grip his rigid cock. He strokes with a rhythm that only comes with time, his eyes half-closed in concentration. The room is filled with the quiet symphony of his pleasure, the sound of his hand moving up and down his shaft, the hitch in his breath as he nears the edge. With a grunt, he tips over, his cock jerking as it unleashes a torrent of cum, painting his stomach with sticky, white stripes.
