"Hear that, Mitzi?" Gwen called down to her pussy-eating daughter. "Your aunt tits right in. We've got a new one in the family."
"Oh, wow! Will Uncle Ernie be surprised!" Mitzi gleefully predicted from below.
"Natch. It's a surprise party, isn't it?" Gwen bubbled. "And Ruthie getting it on with the rest of us is the last birthday present Ernie could've expected."
"When're we gonna spring it on him?" Mitzi asked.
"We'll leave that to your dad," Gwen said. "Sooner or later Ernie has to notice the rest of us are gone. When he does, your dad knows what to do."
And overhearing this, her belly now full of teenage cum after draining her nephew's cock, Ruthie outspokenly joined the discussion swirling around her.
"Then let's make it something really worth walking in on!" she excitedly suggested, her tongue still thick with Ned's jizz.
Ruthie scooted over to where her niece and sister-in-law were kneeling at Gwen's rear.
"I've always had this crazy fantasy about sticking my tongue into another woman's tight asshole," Ruthie explained. "Especially while somebody else was eating her pussy at the same time. Dreamed about it so many times, but never thought it'd ever come true. Now, though, what used to seem crazy makes soooo much sense that I can't wait to try it for real!"
"Is this real enough for you, Ruthie darling?" Gwen asked over her shoulder, then reached for her plump asscheeks to spread them for her brother's butt-hungry wife.
"Mmmmm, it's everything I dreamed of," Ruthie sighed at the sight of Gwen's hairy, throbbing asshole.
"So let's get our tongues to work," Mitzi called to her aunt from in front. "Mine in Mom's pussy, and yours reaming her where she shits."
"Just watch me dive in!" Ruthie swooned with anticipation, then buried her face between the half-moons of her sister-in-law's bare ass.
Next it was Mitzi's turn, as she got back to feasting on pussy. When her tongue squirmed into the juicy slot, she could feel her aunt's reaming tongue through the thin wall separating her mother's cunt and asshole.
And on the receiving end of the dual slurping, Gwen sighed. "It's fantastic! Feel like I'm getting eaten alive! God, what a way to gooooo!"
But everybody in the bedroom wasn't satisfied. Left out and hard again, the one male member of the family present let it be known that he was impatient to plug back in.
"Hey, what about me?" Ned sounded off.
"Think you can figure that out on your own, stud," his mother replied. "Just pick yourself a fresh spot and go for it."
Immediately sighting a likely target, Ned panted, "Yeah. Now there's a cunt that sure as hell needs every inch of my big prick."
He'd focused on his aunt. As she knelt to eat Gwen's ass, Ruthie's own ass was raised. With her skirt having ridden up around her hips, her cunt flexed invitingly from the rear through her clinging panties, darkening the taut fabric with a moist stain of leaking liquid arousal.
"Man, I can smell that pussy it's so horny for my prick," Ned noted with a whiff, as he lined up behind his aunt with ten inches in readiness to strike.
First he had to do something about the sopping panties. He was in too much of a hurry to take them all the way off, so he hooked a finger under the elastic and tugged their crotch band aside. A jungle of curly hair greeted him. His aunt had a bush that equaled his mother's. And at its center, framed by spread pussy lips was a tunnel of pink that begged to be fucked.
Ned wasted no time in putting it in. The fit was even tighter and juicier than he'd expected. Plus, his aunt immediately began rocking to and fro, providing the classic friction between cock and cunt that fucking's all about.
"Well," Gwen asked now that he'd made it a foursome, "does your auntie's pussy have what it takes?"
"A piece of ass doesn't get any better," Ned enthusiastically answered. "Wonder if Uncle Ernie has any idea how hot she really is."
"The husband's always the last to know. But he'll find out soon enough," chuckled Gwen.
And, sure enough, at this very moment Gwen's prediction was on the verge of coming true, as in the living room Vic Morgan said to his brother-in-law. "Looks like the party's going on without someone else. What do you say, Ernie, why don't we go down the hall and take a look at what we're missing?"
Ernie shrugged without comment, having long since stopped trying to figure out what kind of evening this was supposed to be. A couple of times he'd hinted to his wife's brother that he'd appreciate knowing why Gwen had arranged for his wife to be there, but Vic had changed the subject. So by this point Ernie had given up, simply going through the motions of lasting out what had become a birthday he'd just as soon forget.
Listlessly, he followed his brother-in-law down the hall, then Vic said to him, "There they are. Hear them?"
Ernie abruptly tingled with alertness. Yes, he certainly did hear them. And the sounds were strikingly similar to those with which he'd recently become so very familiar in this house.
"Vic," he said, glancing pointedly toward the noisy bedroom at the end of the hall, "what the hell's going on in there? Ruthie's with them, isn't she?"
"See for yourself," a smirking Vic suggested. They'd reached the door. It was ajar. Vic kicked it open, then stepped aside and let his wife's brother get an eyeful.
"My God!" Ernie blurted in shock. For he was suddenly a witness to a family orgy, with nobody else but his ass-licking, dog fucked wife in the middle of it.
His niece was the first to respond to his shock. Interrupting her pussy-eating, Mitzi spoke for everyone in the family as she sang out. "Happy birthday, Uncle Ernie!"
What could Ernie do? If he didn't join in, he'd be the only one who wasn't part of the orgy. For Vic's stiff cock was out now, and Mitzi was urging her father to fuck her.
Then, because almost wasn't enough, she'd dive right back into the thick of the best thing that had ever happened to any family.
