He rolled her over and spread her slender legs.

"Daddy!" she wailed. "What are you going to do?"

"I'm going to duplicate your sin, daughter – for your sake, for your peace of mind. As much as I hate the thought, I feel I must I'm going to commit the wicked sin of incest!"

"Daddy!" she cried again.

But she made no attempt to close her legs. Her father mounted her and pushed his big, gnarled prick up her cunt and began to fuck away with all the energy of a whirling dervish.

Each time he slammed his cock meat up her aunt, he said: "Oh, I hate doing this terrible thing!"

Elizabeth, starting to get the idea, shoved her pussy enthusiastically down to meet his pounding prick and cried: "Oh! I'm such a naughty girl! Oh, how horrible this is!"

She arched her slender back and met him fuck-stroke for fuck-stroke. She wrapped her legs around him.

"Get it over with, Daddy! Fill my cunt with your lovely – errr – l mean, spend your incestuous lust in my loins quickly, so we can stop sinning."

Soon enough, he spurted a heavy dose of hot jism into his daughter's cunt and she melted, coming at the same time.

"That was awful," said the dutiful father.

"It sure was," said his daughter.

But why were they both smiling in such a contented fashion?

Later, Elizabeth said: "I sure appreciate what you did for me, Daddy – sharing my shame that way."

"It was my fatherly obligation," he said.

She was looking at him in a demure way, eyelashes lowered and fluttering, lips twitching as she struggled not to smile.

"But, Daddy, I'm still embarrassed," she said. "I'm no longer ashamed about fucking Uncle Charley, now that you have committed incest, too – but I'm still ashamed about sucking him off!"
