Unaware of the world outside, the young man's focus narrows to the sensations coursing through him. His hand, slick with pre-cum, glides effortlessly along his length, each stroke bringing him closer to the edge. His other hand teasingly cups his balls, rolling them gently, sending jolts of pleasure up his spine. He's a study in contrast, his face a picture of concentration and ecstasy, his body a symphony of tension and release. As his orgasm hits, he bites his lip to stifle a moan, his body convulsing as he paints his stomach with his release.
