Alone in his room, a young man, Mark, finds solace in his own hands. His thick, uncut cock throbs with anticipation as he strokes it slowly, his mind racing with forbidden thoughts. The room fills with his heavy breaths and the slick sound of his hand working his rigid flesh. He imagines the touch of another, the tightness of a mouth, or perhaps a welcoming pussy. His body tenses, his grip tightens, and with a low groan, he releases his pent-up desire, his seed spilling out onto his heaving chest.
