The bathroom becomes a canvas for his desire, as he grips his black cock, feeling its throbbing pulse. His hand moves with practiced ease, knowing every ridge, every vein. The sound of his stroking fills the room, a symphony of his lust. His body tenses, his abs contracting as he nears the edge. With a final, powerful stroke, he groans, his cock pulsing as it releases a torrent of cum, coating the floor in his sticky, white seed.
