He could barely see the outline of her tits under the clear water, and his cock was pressing against his shorts with tingling hardness. He didn't know what she was doing with her hand under the water, but he imagined she was sticking a finger into her pussy. He liked to think of his mother doing that when he watched her in the tub. When he thought of his mother shoving her finger up her cunt, he didn't feel so guilty about jacking off. To his way of thinking, if his mother could do it, so could he.

He had never really seen his mother naked. She was always in the water before he saw her. But he knew she was naked though, because he could always see her tits shimmering under the surface. Still, no matter how hard he tried, he could never catch her naked.

Donny had seen a girl naked before though. She lived a mile and a half away in another house almost as isolated as this one. She enjoyed having him look at her body, but they had never had the nerve to touch each other.

With the desire to see his mother's body, Donny went downstairs and out onto the redwood deck. He sprawled into one of the chairs near a table, looking at his mother.

Hearing her son come out, Marilyn quickly removed her finger from her gripping cunt and smiled up at him. He sat with his legs wide, his ass shoved down on the chair. Marilyn almost asked her son to get into the hot tub with her before she remembered she was naked.

It had become a habit not to wear any clothes and a few times she had completely forgotten about it.

She smiled at him, her eyes seeing his young, handsome face with the deep brown eyes. As young as he was, he was tall and had a good body. His shorts, the loose-legged type, rode low on his stomach. As she looked at him, she allowed herself a tantalizing peek between his thighs. A light glowed in her eyes as she thought she could see the tip of his cock. She strained here eyes, and a soft gasp bubbled from her.
