"Lick it, you cock sucker," Mike cried out, jabbing his hips upward. "Oh… fucking shit, eat my cum, bitch!"

As he said the words, his cum-load burst from his nuts and showered up the center of his prick. The molten liquid seemed to boil in his cock head for a long while, then finally into mouth.

"Mmmmfffff!" Gina choked, unable to believe the enormous amount of jism he had squirted into her throat. Some of the thick, creamy juices blasted upward, behind her nose, where they boiled from both nostrils. Other lava-like globs swept into her checks, under her tongue. Soon, her entire mouth and throat were full to overflowing, and still he thrust in more! She gave another groan as her own climax peaked, electrifying her insides.

"All… of it, cock sucker," Mike grunted, feeling the bulk of his load burst from his cock head. "Gargle it down and lick me dry, baby."

As his mother worked on his prick like a starving animal, Mike felt a release like he'd never known before. Most girls had to be coaxed to do this, and when they did, they most often wouldn't take it in the mouth. But his mother! Christ, she was eating that stuff down like there was no tomorrow.

Gina sucked the last silvery drop of jism, then crushed her face fully into his sweaty crotch. She twisted her head around and squeezed her knees together, milking one last spasm of pleasure out of her orgasm. Finally, she relaxed and closed her eyes, moaning around the rock-hard shaft.

"Wow," Mike gasped, "no wonder Dad is so crazy about you. You suck dick better than anyone!"

His words brought Gina back to reality. My God, she thought, what has happened? I've sucked off my own son! I took his huge cock in my mouth and swallowed his cum!
