In the quiet of his room, a man, Hoan Yến Bái, indulges in his private pleasure. His uncut cock, thick and veined, throbs in his hand as he strokes it slowly, building anticipation. He lets out a low moan, his other hand cupping his balls, gently rolling them. His eyes, half-closed, take in the sight of his rigid member, slick with pre-cum. He picks up the pace, his breathing ragged, until he reaches his peak, hot streams of cum coating his hand.
