With a quick glance over his shoulder, the boy ensures he's alone. His heart races as he locks the door, the anticipation of his secret act sending shivers down his spine. He sits on the edge of his bed, his hands trembling slightly as he unzips his pants, revealing his hard, pulsing cock. He takes it in his hand, his grip firm and steady, stroking it up and down, his eyes closed, lost in his own world. His movements grow faster, more urgent, his breath coming in short gasps. He feels the tension building, his body tensing, and then, with a low moan, he releases, his cock pulsing as he spills his load onto the floor.
