In the dimly lit room, a solo boy discovers the joy of self-pleasure, his hand tentatively exploring his growing erection. He strokes himself, his breath hitching as he feels the intense pleasure of his own touch. His imagination runs wild, picturing the girl from his class, her laughter echoing in his mind as he picks up the pace, his cock throbbing in his hand. He lets out a low groan, his body tensing as he finds his release, his fluids coating his hand, a satisfied smile playing on his lips.
