In the quiet of his room, a young man finds solace in the bite of his teeth. He's alone, but his mind is a whirlwind of sensation. He clamps down on his arm, feeling the satisfying give of flesh, the sharp tang of blood. His cock throbs in time with his pulse, aching for release. He strokes himself, the bite marks a stark contrast to the soft, smooth skin of his cock. He's close, so close, his body tense, his breath coming in short, sharp gasps. Finally, he tips over the edge, his body convulsing as he spills his seed, his teeth still sunk deep into his flesh.
