"Oohhh, Billy!" she hissed, rubbing the had of his cock about her tingling clit. "Oh, Billy, Billy."

Quickly, she pressed his cock downward, sliding it along her steaming cunt slit. She moved her hips slightly, and the head of her son's cock moved between the fiery pussy lips. Joan gave a soft, eager sob of anticipation, her hips twisting.

"Oooo, God!" she sighed, moving her hips, fucking her cunt onto her son's throbbing hard prick. "Oh, God, Billy!"

Billy's young body was shaking in pleasure. He stared down at his mother's cunt fucking onto his prick, feeling the wet heat. Joan paused with half his cock inside her cunt, purring with pleasure. Her cunt tightened about his cock. Billy's eyes almost closed with pleasure. Slowly, very slowly, Joan pulled the rest of her son's cock into her cunt. She felt the sensitive lips of her cunt on the base, his cock deeply buried, his balls pressed against the cheeks of her ass. For a long, breathless moment, she held him there, neither of them moving. They hardly breathed.

Her son's cock, so young and yet so big, seemed to fill her cunt to capacity. Her pussy felt deliciously stretched around the hardness. She felt his cock throbbing inside her cunt, and her cunt responded by squeezing.

"Ohhh, do it, do it!" she groaned, her eyes now closed tightly. "Do it to mother, Billy! I want it… I need it! Fuck me, darling! Oh, baby, fuck mother!"

Her hips began to churn up and down as she sat on the edge of the bed, ass hanging over. Billy was just small enough to stand between her creamy thighs. Joan lay back, her hands clutching the edge of the mattress, her hips grinding frantically, her cunt fucking back and forth on his cock. Billy, amazed to see his mother fucking him, stood stiffly, his eyes watching the way her hairy cunt fucked back and forth on his prick.
