In the privacy of his room, a curious 18-year-old explores his body's responses to pleasure. Slowly, he strips off his clothes, revealing a lean, toned physique. His cock, already semi-hard, twitches as he wraps his hand around it, feeling the velvety softness. He closes his eyes, losing himself in the sensation, his strokes becoming more confident and urgent. His breath hitches as he feels his orgasm building, the pressure in his balls intensifying. With a low moan, he comes, his cum spilling over his hand and onto his stomach.
