He began pushing harder, and suddenly the hole gave way completely and his finger popped in to the first knuckle.

Brenda momentarily cringed from the slight pain caused by this unnatural invasion, but her anguish was quickly replaced by an all consuming passion as she frantically wriggled her ass back against his hand.

"More, Goddamn it, more!" she wildly demanded. "Give me all of your fuckin' finger!"

Frank continued worming his finger around in her hot buttery rectum until it was buried to the palm of his hand. Quivering from the delicious sensation, Brenda excitedly screwed her ass back hard against his deeply embedded digit.

Seeing the feverish lust in her eyes, Frank began rapidly screwing his finger around deep in her writhing ass. Through the thin wall of flesh that separated her two passages, he could feel the hard underside of his thickly swollen cock drilling in and out of her cunt.

Robin was so turned on watching that she had her hand up under her nightie, excitedly rubbing her own juicy twat. She'd never heard of a guy sticking his finger up a woman's ass, but from the expression of rapture on her mother's face, it sure must feel good.

"Oh, yes! Yes!" squealed Brenda. "That's the way to do it!"

The horny woman was panting heavily as he began skewering her with both his finger and cock, maintaining the same rhythm of strokes as she writhed above him. Trying to get even more of the handsome man's finger up her shitter, Brenda leaned lower over his body, exposing more of her buttocks to allow him easier access to the heavenly ravishment of her two tingling holes.

She could feel his steel-hard cock throbbing inside her, expanding even thicker from the feel of her slick, hot pussy flesh sliding up and down over it.

"Oh, Jesus, it's so good!" she moaned, writhing her ass back against his palm.

Frank's balls tingled and ached from the hot swirling sperm that was screaming for release as his finger drilled into the tight slippery asshole with deliciously long strokes that matched the steady rhythm of his prick into her juicy cunt. Sensing that his beautiful fuck mate was approaching a climax, he began fucking into her at a faster tempo, exerting all his power to bring her to a mind-blowing orgasm.
