He sits on the edge of the bed, his fingers dancing over his skin, pinching, teasing, as he imagines another's touch. His strokes become faster, more urgent, his body coiling like a spring ready to snap. He throws his head back, a low groan escaping his lips as he spills over, his body shuddering with the force of his release.
