In the dimly lit room, the boy follows the instructions, his heart pounding. He starts slow, his hand tentatively exploring his length. His grip tightens, his strokes becoming more confident. His breathing becomes ragged, his body flushed. He pauses, looking around, then resumes, his pace quickening. His body tenses, his grip tightening. With a final moan, he comes, his cum splattering onto the floor, a look of relief and satisfaction on his face.
