Lost in thought, a young man finds himself alone in his room, his hand idly playing with the growing bulge in his jeans. With a quick glance at the closed door, he unzips, his cock springing free, already hard and eager. He takes it in his hand, marveling at the velvet softness of the skin, the steel beneath. He strokes, slow and steady, his eyes closed, lost in the sensation. His other hand cups his balls, rolling them gently, sending jolts of pleasure up his spine. His strokes become faster, more urgent, his breath coming in short gasps. He feels the familiar tightening in his balls, and with a final, powerful stroke, he comes, his cock pulsing as he paints his chest with his warm, creamy seed.
