For the next two days, Karen seemed to be in a constant state of arousal, her tits swollen, her nipples extremely sensitive, her cunt pulsating wetly. She was more excited than she could remember, even more than that long-ago day when she found out she not only loved to fuck, but craved a hard cock the way some girls craved to date the campus hero.

Since visiting Sissy's office, she noticed, too, that Richard stayed in the house more than ever. He had no interest in racing about the neighborhood, playing ball, riding his bike or anything else but being with her. He was, at first, shy when they came from the doctor's office, quiet and seemingly embarrassed that she had seen his cock shoot jism. But before bedtime that night, he was a chatterbox, talking a mile a minute about anything and everything but what had happened earlier.

Karen wasn't about to let him make his next appointment alone. She wanted to see what happened next. She admitted to herself that she wanted to see her son's cock and balls, watch Sissy make him come again. On the other hand, she felt a burning desire to give his balls a squeeze, herself, to feel his cock throbbing in her hand, making him come.

Now, two days later, she was aware that Richard walked about with a hard-on most of the time, not even trying to keep her from seeing it. He seemed proud of his hard cock, glancing at her often to see if she was noticing it. Karen was seeing his prick, all right. She couldn't keep her eyes, off the front of his pants, watching his cock bulge against them, her hands itching to take it, her cunt pulsating for his prickhead, her mouth watering in cocksucking hunger.

It was almost ten in the evening, and she sat on the couch in the living room. Her son sprawled in a chair, his legs stretched out. The front of his pants bulged, as it had been for the past two days. Karen looked at him openly, no longer secretly looking. She enjoyed seeing his cock hard and there was no reason why she should not look.
