Jerking her hand off her ass, she darted it under her thin sweater. She didn't hear the gasp of her son as she exposed her tits. Feverishly pulling and twisting her nipples, Roxie began to fingerfuck herself with vigorous strokes, arching her crotch. Her panties pulled away, and her son gazed in steamy fascination, now able to watch her two fingers penetrating the hairy wetness.

"Ooohhhh, yes!" Roxie sobbed. "Oh, yes!"

A low whine came from her as her ass lurched upward. The whine changed to a throaty scream. She buried her two fingers as far into her cunt as she could, smashing one of her tits almost flat with her palm.

"Yes! Ohhhh, yes!"

Rich saw his mother shudder, then her hips seemed to start jerking out of control.

"Oooooommmmmm!" She strained her cunt onto her fingers as the convulsion burned through her, her stomach rippling. Then, as the spasms weakened, she let her ass slump, but her fingers were still inside her cunt.

Rich kept watching, seeing the stretching of her pussy. His cock almost burst from his jeans Roxie slowly pulled her fingers from her cunt, her legs moving together slowly.

By the time she was sitting up in the car, Rich had closed the garage door, and she never knew he had been watching her.

With a blush on her lovely face, she stood on shaky legs, smoothing her skirt down, returning to the washing machine. She felt dazed for a moment, concerned that she had weakened and given in to the wicked urge.

Then a smile spread over her face, eyes gleaming softly.

She felt good, very good.

The relief had been needed.

But she still felt ashamed of what she had done.

However, her relief was short-lived.

Soon after dinner, Roxie was horrified to find those urges coming on again, stronger than they had been that afternoon. She was sitting in the living room with her son, watching television, when her clit started swelling.
