She was so absorbed in this unusual fantasy not realize Jack was watching her.

Nor did she realize that when she sat down, the robe had parted again. One of her tits was exposed, the hard nipple throbbing just out of the flap. Her upper thighs, too, could be seen. And her son was seeing it all.

By the time she understood that her tit and thighs had been revealed, it was too late. She saw Jack had a hard-on. It was bulging inside his tight jeans, along the side of his left thigh. It was so hard, the outline of his cock was perfect. She could see the swollen head, the ridge just past it, and the hardness of the shaft.

"Oh, damn this robe!" she hissed pulling it over her tit.

But as she started to cover her thighs, something came over Marian. She did it without thinking, in an automatic, deliciously wicked manner.

Instead of simply sliding the folds over her thighs, Marian lifted the material high, and for a brief, tantalizing moment, Jack stared at his mother's thighs and the tight crotch of her panties. It was long enough look for him to see her cunt swelling against the lacy garment and the dark shadow of her cunt hair.

She stared directly into Jack's eyes as she finally covered herself.

Bolder than his mother, Jack grinned at Marian in a lewd way. "Nice," he said, "very nice."

Confused by what she had done, Marian remained in the chair, too frozen to move. Her cunt was on fire again and her tits seemed far too sensitive as the nipples brushed the fluffy robe. There was a strange sensation between her thighs, a feeling of impending orgasm. After a while, she struggled out of the chair and without looking at her son, left the room. Marian spent the remainder of the day in a tingling, burning desire. Wearing a becoming housedress, she felt a heavy disappointment because Jack had left the house an hour after their little encounter and was gone all day. Her over-heated imagination saw him with Judy, concealed someplace, sticking his cock into her tender cunt. The more she thought of him fucking the cute little girl, the hotter her jealousy became.
