If being fucked by him twice in less than an hour was any indication, Marilyn knew she was going to be fucked frequently and fucked beautifully.
After a while she struggled up. "Why don't we take a shower together, Donny?"
"That would be fun, Mom," he agreed.
He jumped to his feet and she watched his cock swing about as he started up the stairs. She followed a few feet behind him, watching his naked ass happily.
CHAPTER THREE
Later that afternoon while the sun was still high, Marilyn and Donny rode their bicycles through the pines.
It was something they had done often shortly after her divorce. They hadn't done it much lately but today the wonders of nature drew them into the woods.
Donny still wore his shorts, but Marilyn had put on a short tennis-type dress and blouse. Beneath the skirt she had on quite lacy, very sheer, bikini panties. Her son seemed to never get his fill of looking at her slender thighs, and she decided to dress in a manner that revealed them to him.
They rode slowly along a narrow trail between the tall trees, the sun filtering through. About a mile from the house they paused. Marilyn stood astraddle her bicycle, the rear of her skirt caught on the seat. Donny was slightly behind his mother and he gazed excitedly at her thighs. He could see not only her long thighs, but also the roundness of her ass where the skirt was held up. The tingle in his crotch caused his cock to harden, and when Marilyn glanced at him, it was the first thing she saw. A slow smile spread over her face and her eyes grew warm.
"Do you always stay so hard, Donny?" she said in a low voice, licking her lips.
"Only when I look at you, Mom," he replied, rubbing at his bulging prick. "Did you know I can see your ass?"
