"Oh, fuck me, Walter!" The girl was obviously in the throes of ecstasy. She sounded very young. "Unngh! Oh, fuck me with your big cock, fuck me hard! Make me cum, Walter!"

Patty put the groceries on the kitchen counter. She was trembling. She went upstairs, her mind already filing with obscene images, of her hung son slamming his dripping prick into some lucky little slut's gooey cunt.

The voices grew louder. Her son's bedroom door was open. Patty told herself not to look, told herself that the sight of her son fucking another girl would again put her incestuous lust for him over the edge. Patty couldn't help herself. She stood in the open door, staring in.

The girl was young, blonde and slinky. She was on top of Walter, who lay on his back, smiling up at her, his hands folder behind his head. The girl had a very quick, nimble ass, and she was now gyrating it in a frenzy, frantically pistoning her wet little pussy up and down Walter's cock.

"Gonna cum," the girl panted. She clutched Walter's shoulders, shuddering as she slammed her hairy little fuck hole onto the base of his prick. "Fuck me, Walter. Love your prick, Walter! Fuck me, fuck me…"

"Get out," Patty hissed.

"Oh, shit!" the girl said.

The girl leapt off the bed, making Walter's cock slide out of her pussy with an obscene popping sound. Patty advanced on her menacingly. Thirty seconds later, the anonymous little slut was gone, having set a potential world record in wiggling into her clothes and dashing down the stairs.

She was alone in the house with her son again. Patty stood at the foot of the bed, breathing hard, staring at her son's enormous cock.

"What was the meaning of that?"
