She noticed her son looking at her as his sister wiggled on top of him, and although she was blushing deeply, she couldn't say anything. Barry grinned at her, and she quickly lowered her eyes to the book. But the words blurred, and she kept lifting her eyes to watch Shari's wiggling ass. Shari spread her slender legs along the outside of her brother. Janet could see the tightness of those shorts, Shari's crotch, the creamy, inner smoothness of her long, young thighs.

Janet saw Barry slide his hands down to his sister's ass and cup Shari's little ass-cheeks, bringing a moan from Shari. Barry was watching his mother as he pushed upward on his sister's hips, and Janet gasped softly when she saw the head of his cock push from the frayed leg of his cut-offs. It was only a quick peek, then Shari smashed her pussy back onto his cock, hard.

But Barry had seen his mother's reaction. He had seen the sudden flare of heat in his mother's eyes, heard the soft gasp she made. He cupped his sister's tightly clad ass and clung to Shari's ass-cheeks openly as he watched his mother. He pushed his cock up to his sister's hot, little cunt, making Shari squeal softly with sensation.

Shari's young body trembled, and the cheeks of her little ass clenched. She pressed hard onto her brother's throbbing cock, and whispered into Barry's ear, "You made me cum."

Janet barely heard the words.

After a moment, her body shivering, Shari climbed from her brother. She sat on the other side of him, facing their mother. Shari saw the head of his cock sticking from his cut-offs. With a soft giggle, she pulled her brother's cock from the leg of his shorts. Barry lay still, gazing at their mother.

Janet's gaze burned on his cock, unable to avoid seeing it. She stared as if hypnotized, her book now resting in her lap.

Shari looked up at their mother, and with a hot expression in her young eyes, closed her fist about her brother's cock and began to wantonly jack it. Both Barry and Shari stared at her, and Shari's tight fist moved up and down his cock. Janet was blushing; she could feel the heat on her face, but there was nothing she could do about it.
