In the dim light, the man starts to stroke his cock, the pre-cum already glistening at the tip. He grips it firmly, his hand moving up and down in a steady rhythm, his breathing quickening as he loses himself in the sensation. His other hand cups his balls, gently squeezing as he picks up the pace, his wrist flicking as he approaches the edge. He leans back, his body tensing as he releases, his cock pulsing as he coats his hand with warm cum.
