Karen looked at her mother closely. "Mother!"

Susan laughed, low and husky. "Don't act so shocked, honey. You're just like me, and you know it. You had Robert's cock in your hot little hand, jacking it."

Karen flushed deeply, looking down shyly. Susan laughed again. "Play with it again, honey," she urged. "I want to watch you play with Robert's cock."

Karen gazed at her mother, her eyes wide, filled with pleased excitement. "You want to…watch?"

"I might even play with his cock, too," Susan replied. "But only if Robert can keep a secret."

"1 can!" Robert yelped in his childish voice. "I can keep a secret real good!"

"I thought you could," Susan laughed, swinging one knee back and forth.

"Are you sure, mother?" Karen asked, doubtful.

"Play with his cock and see, baby," she laughed throatily. "Take his cock out of his pants and see if I don't like it."

She watched her daughter open Robert's pants, and her breathing increased when she saw his cock again. Now that Karen understood, she gleefully clutched at Robert's cock with her hot, tight little fist, pumping on it.

"Take his jeans down," Susan said. "The way you did before. Let's see his balls, too, Karen."

"Golly, yes!" Karen squealed as she tugged at Robert's jeans.

Susan trembled with excitement and bubbling desire as she watched her daughter lower Robert's jeans, his still hard cock coming into view. She held her breath as Karen wrapped her fingers about it, pumping slowly. Karen, jacking on Robert's cock, kept her glowing eyes on her mother. She saw the way her mother's tits strained at the thin blouse, her nipples sweetly outlined. Lowering her eyes, she saw the tightness of the crotch on her mother's cut-off jeans, the curling dark hairs that were exposed.
