But she finally remembered, after her wildly pumping fist had made almost half of the geysering cum-load shoot onto the carpet. Moaning loudly, the naked mom plunged her lips back over his throbbing, erupting cock. Then she contentedly started swallowing and sucking loudly at the same time, letting the rest of his cock-juice shoot across her tongue, splashing on the roof of her mouth, running down her throat.

Mark held her head, jerking his hips convulsively off the mattress as the cum kept streaming up from his balls. Sharon eagerly gulped it all down, smacking her lips around his spewing cock-shaft as she savored the taste of his cum. Finally she slid her wet mouth off of his cock, her belly feeling warm from all the cum she'd gulped.

"Oh, Mom," Mark groaned. "I swear, I thought you were going to kill me! I never came that hard in my life!"

"I'm sure you didn't, baby. But it looks like you've kept your promise to Mom, haven't you? You've still got a nice, big hard-on, don't you? Now, Mark, would you like to fuck your mother's cunt?"

Mark nodded. Being kept on the brink of squirting for so long had made his stiff cock really ache, so that he would have to blow several wads in a row before his prick would even be capable of getting soft. Now the massive organ grew stiffer than ever as his mom rose before him, again showing him the spectacular voluptuousness of her naked body, her rich, black-furred cunt-mound, her enormous, stiff nippled tits.

"I'm going to lie on my back, Mark, so I can put my legs over your shoulders. Your cock will really go in deep that way."

The naked mom's huge tits quivered firmly as she slid onto her back on the bed, never taking her eyes off of her son's rigid cock. She wiggled her ass into a good humping position, then lifted her legs high in the air. Mark stared at her wide-open, curly-haired pussy, seeing how wet and swollen her pink cunt-slit looked, his massive cock throbbing in anticipation as he realized that he was about to bury his giant fuck tool into his own mother's cunt.
