"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.
Wendy thrust her hand under her belly, gaping through her pussy curls for the opening of her cunt slit. She sank two fingers deep inside her creaming cunt, gasping with satisfaction as her pussy sucked around them, just as her whole sucked her uncle's cock.
Uncle Bob was still guiding his prick home, forcing it farther and farther into his niece's bowels. There was a little bit of pain as Wendy's asshole stretched to admit his cock, but there but there was even more pleasure. Her cock-clasping asshole was throbbing and contracting repeatedly, nursing around the pounding hardness of her uncle's huge prick.
Bob grunted and collapsed on top of her nakedness, stabbing his prick to the balls in the forbidden tightness of the teen's ass tunnel. Wendy moaned as she felt her stretched shit ring suck and pucker around the base of his cock. Feverishly she continued to jack off her pussy, alternating between finger-whipping her creamy slit and rubbing her clit.
"Now start banging it in me good, Uncle Bob!" she pleaded. "My asshole's used to your big cock now! So just fuck it for me!"
Bob pulled slowly out of her smoldering asshole, feeling her sphincter dragging needfully round the receding, length of his prick. He paused with just the cock knob stuck inside her asshole. Then he pushed back into her bowels, fucking his prick farther than ever into her sucking, squirming ass.
Wendy finger-fucked her aching pussy as fast as she could, bouncing her hips excitedly off the floor. "Unh unh, fuck my asshole! Fuck it, Uncle Bob, fuck it good!"
Bob started a slow, heavily driving rhythm, pounding his cum-swollen prick in and out of his niece's Vaseline-coated asshole. Wendy squealed as she concentrated on the length of his cock shaft, feeling it rooting deep inside her shit tunnel. Happily she continued to play with her pussy as she fucked up her ass to meet her uncle's cock.
"Harder, harder!" she panted. "Fuck my asshole, fuck it fast and hard! It's making me cum, Uncle Bob!"
Bob increased the speed of his fucking, panting on his niece's shoulder as he felt the jism churning in his balls. Wendy rolled her clitty hard under her finger, whimpering as she felt her asshole suck rubbery around his prick.
"I'm gonna make it," she called, her voice cracking.
She started pistoning her peach-shaped ass up like a bitch in heat, hearing her Vaseline-soaked asshole sucking and squishing around his cock.
"Fuck my butt, fuck my asshole! I'm cuming, Uncle Bob! Oh, fuck, cuummmiinnnngggg!"
Her whole contracted tightly around his driving cock, just as her pussy spewed fuck juice all over her fingers. In the middle of her cum, the dazed niece felt Uncle Bob's cock grow as hard as stone up her asshole. He guided her through the peaks of her cum by fucking her butt as hard as he could.
"I'm cumming too Wendy! Oh, fuck!"
The second load of spunk streamed up her asshole, joining the Vaseline in soothing the burning walls of her ass channel. Wendy giggled wantonly as she heard her uncle grunting on her shoulder and felt his cock shooting long strands of prick juice up her ass. Helpfully she flexed her asshole around his hard-on, helping him gush out every drop of cum.
CHAPTER FOUR
"For God's sake, Bob!" Ingrid chided her husband. "Can't you fuck my pussy faster than that?"
Bob said nothing, laboring on top of his wife's incredibly voluptuous, huge-titted body. His huge cock stabbed slowly in and out of her fur-fringed cunt. Ingrid slapped her husband's ass in an effort to make him fuck her faster and deeper, but to no avail. Bob just kept chugging along.
Ingrid wasn't happy about it. She was in her late thirties now, and it seemed that as she'd grown older and her children had matured, she'd become hornier with each passing year. Even as a teenager Ingrid had been plenty horny. She could have had any man she'd wanted, with her blonde, Swedish beauty, her round ass and her enormous tits. She'd picked Bob because of the size of his prick.
They'd been married a long time and Ingrid knew she could still have any man she wanted. Her body had become a little plumper with age, but her already oversized boobs had grown larger too. Her tits were an honest 44-D, and her fat, blood-red nipples showed through any bra.
Ordinarily Bob was just as horny as she was. Throughout the years of their marriage, even when Ingrid had had children to nurse, they'd fucked their brains out at least once a night. She couldn't understand why Bob wasn't fucking her more enthusiastically now. Of course, she had no way of knowing about his fuck-session that afternoon with Wendy.
"Bob, you're not even going to make me cum if you fuck me like this!" Ingrid complained. "Faster! Oh, for God's sake, now you're cumming without me!"
His hips had begun jerking spasmodically between her thighs and Ingrid recognized the movement as a sure sign of jism boiling in his balls. Finally Bob started fucking her faster, pistoning his huge prick in and out of her pussy as he prepared to spurt.
In his excitement, he missed a stroke. Ingrid frowned as his rock-hard prick popped out of her tight pussy and throbbed over her belly. Before Bob could stick it back in, his mighty boner started shooting jism all over his wife's stomach.
"Oh, Bob! For God's sake!"
But it was too late to do anything about it. Ingrid just lay there with her legs spread, sighing as she watched the hot, white cum fountaining onto her belly. Some of it squished all the way up to her tits, and some of it just dribbled on her pussy. When the cum finally stopped shooting out, Ingrid pushed him away from her and rolled off the bed.
"Well, I guess that's all you're going to be able to do for me, tonight," she said unhappily, looking down at the splotches of cum on her body. "I might as well go into the bathroom and clean up!"
It was late at night and Ingrid didn't think twice before leaving the bedroom and parading naked down the darkened ball.
Ingrid rushed to the bathroom, her enormous tits bouncing and swaying pendulously as she felt the spunk running down the insides of her skin. There was a thin light under the door, but she didn't notice it. Ingrid pushed open the bathroom door and gasped at what she saw.
