With her cunt boiling hungrily, she held his hips still, and began to pump her ass back and forth, fucking her son. Marty was mindlessly excited, feeling his mother's scalding cunt holding his throbbing cock, riding back and forth on his prick. He began gasping and moaning with delight, his voice louder than hers. Joan fucked her son with gasping pleasure, trying to look between their bodies, wanting to see his young cock fucking her hairy cunt. She couldn't see much of anything, but she could feel each throb of his cock with the tight, sensitive lips of her cunt. Joan almost immediately began to come, her cunt gnawing and sucking and squeezing on her son's cock.

Mewling in a thick voice, Joan closed her eyes to the ecstasy of fucking her son, to the throbbing waves of orgasms that rippled through her. Somewhere through the roaring pleasure, she heard the tearing sound of her panties, but she didn't care. What she cared about was the throbbing hardness of her son's cock, her cunt sliding back and forth, the shuddering waves of orgasms that shot through her like liquid fire. Marty was grunting now, and she opened her eyes. She saw his face through a film of misty pleasure. His features were contorted as if he was trying to keep from coming inside her cunt, but she had no intention of losing his precious come juice.

"Do it, Marty!" she urged in a hot voice, her hands closing into the bunching checks of his ass. "Don't hold back! Let it go, baby! Oooo, come in me! Come inside me, Marty!"

She felt his hands clawing at her hips. She could feel the powerful throbbing of his cock as her clutching pussy moved frantically, devouring his prick. He was going to come, she knew. She gripped each cheek of her son's ass, slamming her cunt hard against him, holding his cock deep inside with the powerful muscles of her pussy.
