The room is charged with a thick, humid air as the unseen performer takes center stage, his body glistening with sweat. His hand, a blur, works his stiff cock with practiced ease, the sound of his jacking filling the void. His grunts grow louder, more urgent, as he nears his climax. The first spurt catches him off guard, landing hot and sticky on his abdomen. He continues to stroke, his body convulsing as he paints the scene with his cum, a masterbation marathon come to a messy, satisfying end.
