In the dimly lit room, the young man's body glistens with sweat as he explores his own limits. His fingers trace the veins on his cock, feeling the pulse of life that courses through him. He grips it tightly, imagining the warmth of another's touch, and begins to thrust into his fist, his hips lifting off the bed. His other hand reaches down, cupping his balls, rolling them gently as he feels the familiar tingle at the base of his spine. With a final, shuddering breath, he comes undone, his body convulsing as he spills his seed, painting his abdomen with his release.
