She cradled his swollen cumbags to her tits as she gnawed softly on his cock-knob. His long, fat prick stuck out between them like a pipeline connecting the reservoir of his balls to the container of her mouth.

Jimmy humped desperately.

Diana's tawny head bobbed up, stuck on his cockhead but not letting him feed her any more – yet. His cockhead was the most succulent part of his cock and she was enjoying having only that throbbing slab in her maw.

Her hair fell in a golden curtain past her cheeks and brushed over his cock. Her face turned, winding her compressed lips around, adding torque to the suction.

"Ummmmm-ummmm-ummmm!" she purred, making his cock hum as she blew down it.

"Suck my cock, Mom! Suck me off!" Jimmy gasped.

The boy loved having his prick in her mouth, but he was getting desperate to empty his balls off. He couldn't be as patient as she was about the end result. His balls were so bloated that he thought they might blow out like a bursting balloon.

And he knew, too, that from now on he was going to enjoy many repeats of this oral sex that incest, once begun, would be an ongoing event – and a blessed one.

So he saw no reason to hold back his first load, since it was only the first of many.

Jimmy shifted his grip from his mother's shoulders and held her face between his hands. He humped again. This time she let him slide more cock in.

He began face fucking her with a steady rhythm, feeding her more prick with, every thrust. His prick skimmed over her arched tongue as it wedged back toward her throat, and as he pulled back out, her lips distended down his cock, pulled out along his prick as she sucked through every precious inch of the pulsating cock.

His mother's mouth was just like a cunt, Jimmy thought, adoring it. He guessed that Mom probably was the best cocksucker in the world. The thought filled him with pride as well as passion as he marveled at how lucky he was to have a sexy mother who gave heavenly head.
