In the sanctity of his room, a fresh-faced 18-year-old gives in to his desires. His cock, thick and veined, stands at attention, begging for touch. He wraps his hand around it, feeling the heat and pulse, and begins to stroke. His moans fill the room as he picks up speed, his other hand cupping his tight balls. The sensation builds, his abs clenching, until he can't hold back any longer. With a groan, he comes undone, his cum shooting onto his stomach, marking his passage into manhood.
