Bill shivered with horny anticipation as he eased his stiff swollen meat between her silky thighs. He almost never fucked Karen from behind, but today it would be an advantage. Not seeing her face, he could forget she was his wife.
He poked around lazily with the fat knobby head of his cock till he felt himself slipping into the moist little pit of her cunt mouth. Karen was trembling violently, and so was he. No wonder they hadn't been laid in about a month.
He pushed into her strongly, penetrating her deeply in one long delicious thrust. Her aroused wet cunt seethed around him. He was surprised at how aroused she was. She hadn't been wet and hot for him in years.
"Ooooo!" she gasped.
Skewered on that long hard cock, feeling it snake right up to her womb, Karen moaned helplessly with pleasure. Her starved twat boiled around his meat, nipping, grasping. She jammed her butt down hard into his lap, taking his prick inside her as deep as she could. She felt his coarse-haired balls come to rest against her seething pussy.
"Yes, yesss," she whined, "fuck meee…"
But it wasn't Bill she was saying it to. Already she was lost in fantasy. Mark, young and tan and husky, was penetrating her lustily from behind, and she was responding eagerly, shamelessly.
"Fuck me, fuck me," she chanted. "I want it…"
Bill was amazed at his wife's behavior. It'd been years since she'd responded like that to his love-making, using dirty wards to say how much she liked it, moaning helplessly, creaming floods of steamy juice all over his cock.
Poor Karen, he'd neglected her. She must be really hard up.
He couldn't keep his mind on her, though, because as he sank his swollen cock into her slick, hot, nipping hole, he was thinking of his adopted daughter Stacy.
It was Stacy, saucy little butt wriggling wantonly in his lap, who cried out huskily, "Fuck meeee."
Bill snorted with excitement and began working his meat in her, too aroused to be gentle. He fucked her in deep powerful strokes, plunging in all the way to his balls, raking and stuffing her red-hot, squeezing box.
"Baby, baby," he moaned, "is it good?"
"Ummm," she sighed. "Yessss… Oh, YES I love it… Don't stop…"
Karen creamed helplessly as the long thick cock reamed her long-starved twat. She couldn't control herself. Her hips pumped furiously in time to his strokes, and she moaned aloud. Filthy words came to her lips, and she grew wanton with pleasure.
"Ball me," she whined. "Stick it in me… Yes, oh, yesss…"
Bill's belly smacked loudly against her pumping ass, and the noise of their fucking grew lewdly wet and slurping. The bed creaked and groaned. They were lost to everything but their own thrilling fantasies and the dizzying pleasure of this long overdue fuck.
Bill imagined his sexy little niece writhing and squealing with joy as he balled her tight teenage cunt. Karen grew hoarse and panting as she fantasized her handsome teenage nephew fucking her furiously from behind.
"Do it, do it, DO IT," she screeched. "Do it to meeee…"
"Aw, Christ," Bill panted. "It's good… You're so fuckin' hot… Yeah…"
Karen suddenly arched her body sharply as she felt herself spinning into a delicious climax. Her normally cool sedate face twisted in a horny leer, and she felt her cunt going into spasms of pleasure, literally squirting steamy juice.
"Oooo," she shrieked, "Ooooo!"
Bill felt the silky wet sheath tightening powerfully around his cock, gripping him, holding him deep down in her fiery wet depths. It was too much. It milked the jism right out of him.
"I'm coming," he gasped. "Oh, Jesus, yes!"
He fucked her brutally, ramming his squirting cock out of control in her convulsing box. He felt his come rushing out, flooding her, bathing them both.
They panted and writhed together for a long moment, then fell apart, their feverish fantasies gone. Karen rolled over and looked wonderingly at her husband. They hadn't made love like that in years.
And they still hadn't – because she'd been with Mark in her mind, not with Bill. She blushed with shame.
Bill felt himself blushing, too. He'd never tell Karen, of course, but in the very act of balling her he'd been unfaithful. All the time it had been Stacy he was fucking.
"Well," he said lamely, "that was a surprise."
"Yes," Karen said, lowering her eyes, "wasn't it?"
They rolled apart, turning their backs to each other, lost in thought. Their marriage couldn't go on like this, they both knew. They couldn't live a lie. They couldn't go around lusting for the two teenagers who had become their children.
But what were they going to do about it?
Out in the bright summer sunshine Mark and Stacy lay side by side at the edge of the pool, sunning themselves. Brother and sister, only a year apart in age, they looked like twins, both of them deeply tanned and platinum-haired and radiantly healthy.
Stacy giggled. "Hey," she said to her brother, "did you notice Uncle Bill had a hard-on?"
Mark snorted and turned to look at her.
"Naw," he said, "I didn't. But then I was digging Aunt Karen. Man, what a pair of jugs."
Stacy sighed. "Wouldn't it be far out if we could get it on with them?"
"Forget it," said Mark. "They're so fuckin' middle-class and uptight. No, we gotta find our fun somewhere else, baby sister."
"Like where?" said Stacy. "There's no kids around her. Just old people."
"Well, I'm gonna sneak out tonight and explore," said Mark. "You wanta come along?"
"Yeah," said Stacy. "I'm dying for some action. As soon as they go to bed…"
Having agreed on their plan, brother and sister resumed the pleasant innocent expressions they always used around their aunt and uncle. They'd learned to con adults a long time ago.
CHAPTER TWO
That night after their aunt and uncle had gone to bed, Mark and Stacy sneaked out of the house, looking for fun. Although the brother and sister liked their new adoptive parents, life with the Jordans was too tame for them.
Their father had died long ago, while they were still babies. Their busy working mother had never had time to supervise their activities. Early on, the mischievous teenager had invented this game of sneaking out late at night and finding unusual forms of entertainment.
"What are you going to do, Mark?" his sister asked when they were a safe distance from the house.
"Prowl a little," said Mark. "Look in a few windows. You wanta come along?"
"No, I don't think so," said Stacy. "I'd rather see what's happening at the movies. I'll meet you back at the house."
"Right on," said Mark. "Happy hunting."
The blond brother and sister had a code all their own. Their unspoken mission was to get it on with somebody. Both were very horny after a week with the Jordans and no action.
They parted, Stacy heading south toward the local movie house, Mark going north into the plush suburban neighborhood near the Jordans'. He had no worries about his little sister's safety. He and Stacy had been through many hairy adventures together, and she knew how to take care of herself.
Mark slipped across someone's lawn and into an alley. He strolled along silently in his sneakers, glancing in windows. He spotted a few uncurtained bedroom windows and observed some women undressing, some couples making love nothing special to Mark. He was an experienced peeper and rather particular about what he chose to watch.
Finally he found what he was looking for – an exceptionally attractive woman alone who had neglected to pull the shades in her bedroom.
Mark walked silently into the woman's yard and got very close to her bedroom window, knowing she couldn't see him while the lights were on. Hell, you could practically press your nose against the glass and they still wouldn't notice you. The ones who left their curtains open somehow never expected to be watched.
