Her legs flew up and her arched feet began to kick in the air behind his haunches, pumping and pedaling as if she were riding a bicycle upside down.

Then she jerked her knees right up to her tits, rolling her ass up, curling her curvaceous body up into a ball, rolling into a hoop around the firm axle of his cock.

Dan dipped down and fed her a long, slow, rippling under slung stroke that dragged his balls along the bed. Then he hiked up higher and plowed into her from above, so that he was running every inch of his vibrant cockshaft across her explosive cunt as it sank in and pulled out.

Diana moaned loudly when her clit began to go off like a blasting cap.

It occurred to Dan that their kids might be able to hear his wife's sexual cries, loud fuck that she was. But he was not about to pause to warn her and besides, it turned him on to imagine his sexy teenaged daughter lying in her bed, listening to the sounds of lust.

"Cum – cum – cum!" Diana began to babble.

Creaming, herself, the wanton woman was yearning to feel Dan's fuckjuice squirt up her cunt.

And if the kids were listening – well, that suited Diana quite well, on this eventful day.

Her cunt was going off like a Gattling gun, setting off deeper explosions in the heart of her horny loins. Her cunt was filling up with cum cream and Dan's prick was splashing in like a torpedo launched in a swamp.

"Shoot in me, darling? Jizz me! Slime in my cunt!" Diana begged, at the peak and holding, wanting to still be cumming when her husband joined in the juicy climax.

His balls were so full by this time that they were no longer swinging – they were rolling up the lane of her loins like bowling balls.

"Here it comes, baby!" he howled.

"Oooooh! Ahhhh!" she wailed in anticipation.

The eavesdropping teenagers were left in no doubt that the parental passion was peaking.
