Duke, a mature, virile man, indulges in a private, noisy solo session. His massive, hard cock stands at attention, demanding release. He strokes it with vigor, savoring the sensation of his tight grip around his shaft. His moans grow louder, more insistent, as he edges closer to climax. "Fuck, I'm cumming!" he roars, his body convulsing as he unleashes a torrent of hot, sticky sperm, coating the floor with his essence.
