The locker, his private sanctuary, echoes with the sound of his ragged breaths. He's alone, but his mind races with fantasies that make his cock throb. His fingers trace the length of his shaft, feeling the veins pulse with life. The taste of his own pre-cum, salty and familiar, sends shivers down his spine. He imagines hands other than his own, mouths that aren't his, and the fantasy drives him closer to the edge. His body tenses, his grip tightens, and with a final, shuddering groan, he spills his load into the locker's darkness.
