In the dim light of his room, a young man unzips his pants, his cock already straining against the fabric. He pulls it out, letting it spring free, and begins to stroke. His hand moves up and down, his grip tight, his rhythm steady. He leans back, his eyes closed, lost in the sensation. His hips start to thrust, his pace quickening. His body tenses, and with a final, deep moan, he cums, his cock pulsing, his semen spilling over his hand.
