Denis, alone in his room, begins his private concert. He slowly unbuttons his shirt, letting it fall to the floor, as his hands trace the lines of his torso. His breath hitches as he unzips his pants, releasing his hardening cock. He strokes it gently, his other hand cupping his balls, feeling their weight. His pace quickens, his breath ragged, as he imagines a lover's touch. His cock throbs, and he feels the familiar warmth of release.
