While Donny held himself stiffly, Marilyn could not hold still. She began to move her ass slowly, fucking her son with her hairy, tight cunt. His breath came in hoarse, hot gasps as she moved her cunt back and forth on his throbbing cock, and she gurgled when he finally started plunging up and down. His cock seemed to go deep into her burning pussy, thrilling her, exciting her.

Donny lifted himself and stared into his mother's eyes, his cock thrusting in and out. Marilyn gazed up at her son as she pumped on his prick, a smile on her face. She clung to his tightening ass cheeks as if afraid he would pull that sweet hardness out of her.

For what seemed to be along time, they fucked slowly. But the ecstasy grew hotter within both of them. Marilyn could not keep this slowness up. She began to pump faster, slamming her cunt up and down on his cock with gurgling ecstasy. Her fingers dug into his tight ass cheeks and Donny was now holding her hips, again resting his face on her springy tits.

"Ohhh, so good, darling," she murmured against the top of his head. "So good! Do it faster, baby! Ohhh, please go faster and harder!"

Donny complied, not so much to please his mother, but because his cock demanded it.

The increasing power and speed of his plunging cock caused Marilyn to coo and sigh. Her cunt was gripping her son's cock very tightly, the slippery wetness making a sheath of intense pleasure for him. Feverishly, Marilyn stroked her hands up and down his back, caressing his bouncing ass, churning her cunt into his throbbing cock with sobs of ecstasy.

She felt every throb of her son's cock with the sensitive lips of her clinging cunt. The feeling increased her own boiling desire, and the mild orgasms began swelling like a bursting balloon within her rippling stomach. The waves of orgasms caused her cunt to grip and flex around Donny's cock in a sucking sensation.

She felt her son speed up, his cock moving hard and fast into her cunt now. His balls slapped at her ass, and she writhed and twisted, arched and banged into him. They were both grunting with intense ecstasy now.
