"Paste it on your cock, Uncle Bob!" Wendy whimpered, still holding her ass cheeks as wide apart as she could. "Then smear it on my asshole too! Hurry, Uncle Bob, hurry!"

Bob uncapped the Vaseline jar and smeared jelly liberally all over his stiff, ten-inch prick. He knelt behind his niece's upturned ass and began smearing Vaseline all over her pink asshole. Wendy squealed as he stuck his thick finger deep inside her rubbery ass guts, coating the interior of her horny ass tunnel.

"Okay, Uncle Bob? Fuck my asshole now!" Bob dropped the jar and re-mounted his niece, panting as he prepared to stab his oversized cock into the smoldering heat of her asshole. Wendy waited expectantly as she felt his spongy cock tip nudging into her tightly muscled asshole. A second later his huge, hot cock rod was plowing into her ass.

"Unnggghhh! Oh, fuck, it's big!" Wendy was squirming on the floor in a feverish effort to help him sink his cock into her ass. "It's stretching me, Uncle Bob! It's stretching my asshole so good! Oh, God, I love getting ass fucked! Ram it up my asshole, Uncle Bob! Shove it all the way up my tight ass!"

His niece's torrent of depraved obscenities coaxed Bob on. He could feel her Vaseline-slickened asshole sucking on his cock tip, contracting around the velvety crown as if welcoming his whole prick length into her asshole.

Bob moved a little higher up her backside, changing the angle at which his throbbing boner speared into her horny ass tunnel. Then he started pushing his cock much harder into his niece's vulnerable ass, stuffing first a third, then a half of his blood-swollen cock into her rubbery ass channel.
