"Ohhh, that's so good, Donny!" she whined with a thick voice. "Oh God, baby! So good! Fuck me, darling! Fuck my pussy! Ahhh, you have a beautiful cock, Donny! So hard… so very hard! I love it. I love it!"

Donny was grunting swiftly now, listening to his mother using those exciting words openly. He gazed with glassy eyes at the way she wiggled her ass, seeing the tightness of her asshole. The cheeks of her ass were very smooth, white and creamy. He stopped plunging his cock into her cunt and fondled the ass cheeks, and his mother continued her back and forth motions, fucking him in mindless delight. He saw his cock sink in, then withdraw, her pink cunt lips sucking on his prick.

The wetness, the intense heat, and the exciting tightness of his mother's cunt became too much, as did the sight of her ass fucking him. Once more Donny's young body went stiff and Marilyn felt his cock jerking about deep inside her clamping cunt. As the roar of a fantastic orgasm whipped through her, she still felt her son's cock as it suddenly gushed, flooding her cunt with that sweet, thick, creamy come juice. For the second time in less than an hour her son was fucking her, spurting that precious come juice into her greedy pussy.

Marilyn sprawled onto the carpet, her body shivering as the glow of ecstasy continued through her. She felt her son caressing and fondling the trembling cheeks of her ass.

There was no feeling of remorse. All she felt at this moment was pleasure. She knew there would be no sense in maintaining a modest appearance with her son any longer. She knew, without any doubt, that her body would be available to Donny any time he wanted it. He could bring his beautiful, young cock to her and fuck her any time the mood struck him.
