She hunched her ass wildly, sliding her cunt back and forth on her son's cock with total, erotic abandon. Driven by her jealousy and sudden lust, Marian became mindless to everything but the exquisite ecstasy her son's cock sent racing through her naked body. Cooing and whimpering, she twisted and rolled her shapely ass, knowing that Jack would be delighted and further aroused by it. She was well aware that he was watching her naked ass as he fucked her.

Although she had seldom let herself go erotically with her husband, she had always wanted to. Marian knew the value of erotic motions and soft words of encouragement, teasing and exposure. Her mind had often thought of them, and, since she was excited by all those things, she suspected, that others were too – especially her son.

So she wiggled her naked ass, arching it up so he could see her asshole and watch her wiggle and twist it. She called out lewd words to inflame her son, pleased when he used them, too.

Her cunt, hairy and intensely sensitive, felt the young, powerful throb of his cock between its lips. She could feel the ridges and grooves of his prick and the roundness of his deliciously swollen cock head. She could feel his balls swing back and forth, slapping against her hairy cunt mound. His stomach gazed her hot ass checks and now and then she could even feel him touch her asshole lightly as he plunged his hard cock in deep.

Jack, with his cock throbbing sweetly inside his mother's boiling cunt, could feel the hot slipperiness of her hairy cunt lips. He was thrilled at the tightness of it and the way her pussy sucked and drew upon his prick. The thought went through his mind that his mother's cunt was almost like sticking his cock into warm, slippery butter, but with a tightness that was out of this world. Her pussy wasn't as tight as his fist, of course, but it was tight enough to send ripples of ecstasy through hi young body.
