In the steamy privacy of his bathroom, a man, driven by primal urges, turns an ordinary shampoo bottle into a makeshift phallus. He lathers it up, the suds glistening like lubricant, as he strokes his engorged cock. His breathing deepens, the scent of soap filling the air. He massages his shaft, the cool bottle a tantalizing contrast to his burning skin. His body tenses, his grip tightens, and with a guttural groan, he releases, his cum mixing with the suds, a testament to his solo indulgence.
