After a rigorous workout, Professor Dotadu retreats to the private showers of the gym, his massive cock still throbbing from the day's activities. With the coast clear, he leans against the cool tiles, his hand wrapping around his thick, veiny shaft. He strokes slowly, savoring the sensation, his mind racing with vivid fantasies. His pace quickens, his breath hitching as he feels his orgasm building. With a final, powerful stroke, he groans, his hot load erupting onto the shower floor.
