Jim looked at his mother's face, and Kathy finally lifted her eyes to his. She licked her lips again, and then her son did something that was totally out of character for him.

He drew the leg of his cut-offs up, and his cock lifted free. She saw it only for a quick moment before he turned his back to her, facing the toilet. Her eyes moved over his ass, thinking how compact and tight it was. Then she heard him pissing into the toilet.

"Jim," she said, her voice a bare whisper. "Let me watch you."

Without hesitation, her son turned and moved to the other side of the toilet, holding his cock at the base. His prick was only half hard now, but Kathy's eyes were fixed upon it with hungry heat. The golden piss spurted from his cock, tinkling into the toilet bowl. Kathy stared hard as her son stood pissing, unashamed.

"My God," she whispered, her cunt twitching as she drew her knees back to her tits. Her arms slipped about her legs, hugging them against her titties. Her eyes were bright as she stared at his cock. Jim could see the dark shadow of his mother's cunt-hair as the water deepened. "Ohhhh, my God!"

Kathy could not prevent the sudden clutch of an orgasm. She felt her clit throb, felt her pussylips clutching as if it had a cock inside. The contractions rippled about her cunt, causing her to tremble. Her eyes never moved from her son's cock. Seeing him piss excited her beyond her fantasies. Her orgasm didn't fade, but increased, thrilling her with a series of orgasms that blistered her flesh. Her ass writhed on the bottom of the tub, and she made soft, squealing sounds, her eyes slitted with ecstasy.
