With her mind turning toward erotic delights, Susan looked out over the valley. The house sat almost on the peak of a medium-sized hill, and at night they could see the lights of the village. It was a beautiful area, and Susan had purchased it a few months after her husband died.

It was early spring, yet the weather was almost like the middle of summer. The sun was very hot, boiling down on the raised deck where the hot tub was located.

Susan felt Bob's thigh pressing a little harder against hers, and she peeked at his face again. He was resting his head on the deck, eyes closed, making very soft sounds of self-induced pleasure. She watched his face a moment, feeling her tits swell in the tight cups of her halter. Her cunt was throbbing now. She rested her right hand on her son's thigh and heard a soft gasp come from him. But he was so involved in pleasure, he didn't stop jerking on his cock.

Susan trembled with desire, wanting to hold his cock badly. The palm of her hand started itching, and she couldn't resist sliding her palm a bit higher on his thigh. She had not been fucked for almost a year, and Susan was not the type of woman to go so long without a cock. She was extremely erotic, came easily, and thought fucking was the greatest of all the world's pleasures.

She made no pretense of what she was doing. She wanted Bob to know she was doing this deliberately. She wanted him to know she was aware that he was jacking off. Moving her palm slowly, she stroked his thigh, sliding her fingers back and forth on the inner surface of his leg. Bob paused for just a moment with his fist movements, glancing at his mother. Susan returned his stare, her smoldering eyes sparkling.
