Gmastersex presents an intimate exploration of male self-pleasure. In the quiet of his room, a man strips down, his cock already hard. He strokes it slowly, his other hand cupping his balls, feeling their weight. His breath grows ragged as he picks up the pace, his fist pumping his length. He leans back, his body tensing as he approaches climax. With a final groan, he comes, his semen spurting out, coating his hand and stomach.
