She screamed as her orgasm boiled over, making her cunt contract tightly around his throbbing cock. The squeezing sensations brought a groan from Billy, his eyes rolling in his head. His balls tightened at the base of his cock. He kept fucking into his mother's convulsing cunt, and she held her ass up as he fucked into her. The orgasm ran from her head to toes. Her eyes popped open in delighted surprise as she felt the series of orgasms burning through her. She came hard, very hard, almost painfully so. But Joan wanted it to keep on, never stop. She began to shake violently and, with a wild screech, rammed her cunt down hard, driving his naked ass into the mattress, grinding wildly and furiously on his still-hard cock.

"Come with me!" she screamed. "Come with mother!"

But Billy didn't come.

He wanted to come, badly, but his cock remained hard as his mother began to fuck her contracting cunt up and down it. He shoved his hands behind her, grabbing at her grinding ass cheeks, fucking his cock into her gripping cunt. When his fingers squeezed at her shaking ass, Joan screamed as a very powerful orgasm shot through her.

"Hold my ass!" she screamed. "Ohhhh, hold mother's fucking ass! I can't stop coming, Billy! Squeeze my ass tight!"

One of her tits touched her son's mouth, and Billy began sucking at it hungrily. He dug his hands into his mother's tight ass, his fingers spreading the ass checks. Joan groaned with mindless ecstasy and twisting her ass, felt a finger stab against her asshole. This triggered a harder orgasm, and she pressed her cunt tightly onto his cock.

"Oh, God, oh, God!" Joan screamed time and again, her orgasms shattering her body, her nerves.

It seemed a long time before she calmed down and rested her weight on him. Her cunt held a tight grip about his hard cock. She pressed her tits into his face, giggling in a lewd way. She felt one of his fingers rubbing lightly at the tightness of her asshole.
