"You got it, Mom," he said excitedly. He ran his hands along her thighs, feeling the smooth creamy texture of her flesh.

Joan sat on her son's cock. She shivered, lifting her gown up and off her head. Her tits strained out, nipples very hard. She sat for a long time, her cunt gripping his cock. She thrilled to the buried prick in her pussy, not wanting to move for a while, but to just sit there on him and feel that beautiful hardness deep in her cunt.

She wiggled, then grinned down at him.

"Oh, damn you," she said. "Why do I have to have such a sexy son? Why do you have to always have such a hard-on? Damn you, baby, you know I have to have that hard cock in my cunt!"

She drew her knees up, squatting on him. She lifted and lowered her pussy, fucking him, holding her tits in both hands. Her face turned lewd, a wanton expression that showed her pleasure. Billy watched his mother's hairy cunt fuck up and down on his cock, his tongue licking at his lips. He lifted his ass as bis mother's cunt plunged down, dropping it as she lifted. But Joan never lifted her crotch so high that her pussy lost the swollen head of his cock. She began to make cork screwing motions as she fucked up and down him. She burbled with excitement, her eyes opening and closing as the pleasure grew.

"Oh, Mom!" Billy panted. "It feels so good!"

"I know, darling," she whispered, fucking up and down slowly. "God, how I know! I love it, Billy! I love to feel your cock in my pussy… fucking me. I don't understand it, not at all, but I want your cock so much!"

Billy lunged his hips upward, fucking into his mother's tight pussy.

"Ohhhh, yes, honey!" she gurgled. "Do that to me! Ram it into me hard that way!"

She held her crotch up. Billy fucked up and down, slapping against the puffy lips of his mother's cunt. The force of it made her tits shake.

"More! More!" she hissed.
