In the quiet of his room, a young man, unseen by others, gives in to his carnal desires. His hand tracing the length of his erect cock, he strokes slowly, building a rhythm that matches his escalating arousal. Pre-cum glistens at the tip, a testament to his growing lust. His free hand wanders, teasing his balls, then moving to his ass, a finger pressing gently, exploring. His breath hitches as he loses himself in the sensation, his body tensing as he nears the edge. With a low moan, he erupts, his cum spilling out, coating his hand and abdomen.
