In the dimly lit room, a young lad sits alone, his heart pounding with anticipation. He's been good all day, but the temptation of his own flesh is too great. His hand snakes down, rubbing the growing bulge in his pants. He frees his throbbing member, stroking it urgently, his breath hitching as he imagines forbidden scenarios. His hips buck, pushing his cock into his tight fist, his precum lubricating his rapid movements. He's close, his body tensing, his grip tightening. With a final, shuddering groan, he spills his seed, his body relaxing as he catches his breath.
