As usual, it was Kelly's bountiful sex urge that got things rolling. A look passed between the four of them and there were a few lowered eyelids and nervous smiles, then off came the robes and they stood before their children in their underwear. Karol reached for the light switch and threw the room into total darkness.
"We're all friends, aren't we?" she laughed. "So it won't matter who happens to run into who in the dark, will it? Let's just feel around in the dark and see what happens."
"We're friends okay," responded Curt. "Not to mention being relatives too!"
There was a sound of soft clothes moving over naked skin. The girls knew that their mom and dad must have taken off their underwear. Lilly was quick to follow suit.
"Kelly, you still got your panties on!" she chirped. "No fair!"
"That's okay," chimed in Karol. "I think there's plenty of help around if she wants it."
"Oooo!" cried Kelly. "Sounds yummy!"
"Lie down on the bed if you can find it, honey," said Curt. "We'll all help you get 'em off."
"And we'll all help you get yourself off, too, dear," Karol told her. "Lilly said you weren't quite finished a while ago. We'll take care of that little bit of unfinished business."
It was incredibly dark in the room, more than they had realized it would be. This added more fun to the proceedings.
"Speaking of unfinished business," Karol continued, "whose perky little tit could this be I've got my hand on? Anybody got any ideas who a pair of 'unfinished' boobies might belong to?"
Lilly giggled and pressed against her mom to let her get a better feel. "Not me!" she exclaimed. "I can't think of anybody like that." She giggled. "Maybe you've got hold of Daddy!"
"If she does," came Kelly's voice from somewhere near the bed, "she doesn't have the best part. I've got that in my hand. Right, Dad?"
Curt felt his cock swell under the warm pressure of her hand on his cock. "I'd call that the best part, I think," he agreed.
"Mommy, how come we never did this before?" asked Lilly, hugging her face to her mother's fully packed tits. "This is groovy!"
"This?" joked Karol, reaching for a firm handful of her child's hard little ass. "Or this?" she went on, tweaking Lilly's taut nipples with the other hand.
"Whew... all of it," said Lilly, warming to her mom's intimate touch. "Ummmm, never mind which part I was talking about... just keep doing what you're doing now!"
"What are you doing to that innocent child?" mocked Curt from the bed where he lay with Kelly.
"She doesn't seem to very innocent to me," Karol called back. "Not from the way she's treating my tits."
Lilly had escalated from merely rubbing her face between them and was now energetically sucking the ends of them, her mouth going back and forth like she had experienced from Curt.
A slapping sound emerged from the bed. It wasn't very rapid yet, but there was no question what was causing it.
"Listen to that, will you?" said Karol. "I think maybe Kelly and your dad are doing something naughty over there. Here, honey, let me put my hands over your ears. You're too young to listen to things like that. It might give you funny ideas."
She wrapped her arms tightly around her daughter and playfully pressed her palms over her ears, then let her hands fall over the angular slopes of the girl's shoulders and hip bones. The kid was still going to town on Karol's tits and she was starting to get damned hot from it. She sat on the couch and directed Lilly through the darkness with her. Now maybe there would be room to take proper care of the daughter who was being so very attentive to her mother's comfort and pleasure.
Lilly eagerly slid alongside her on the couch and felt her mom's fingers gently stroke her ass and upper thighs, settling finally in the moist hollow of her pubescent groin. With her other hand she sensually teased her taut-tipped little nipples.
Kelly was getting similar treatment from her dad. But instead of using only his hands on her, he was employing his mouth as well. He had one hand gripping the cheek of her muscular ass, while the other hand, with his mouth, took care of her two juicy tits.
"Oh Dad," she panted, "go ahead and fuck me, will you? Stick it in good and deep."
He climbed on top and sank the shaft of his rock-hard machine into the depths of her hungry cunt. Karol and Lilly could hear more than just fingers going slap slap slap now -- they could quite easily make out the wet, sexy sound of her fat boobs striking his chest and the long lengths of her legs splatting against his.
"Mommy, are they... are they really screwing now?" asked Lilly. "Has he got it in her and everything?"
"They sure are, honey," replied Karol. "But you're a big girl now -- 'screwing' is for kids. What they're doing is fucking, my darling daughter, plain and simple. Fucking!"
"Wish we could see 'em," whispered Lilly.
"Poor baby," cooed Karol. "Isn't Mommy's little girl getting enough love? If you're having to think about how it would be to see them going at it, I'd better get you on your back and give you a nice, hot little work-out. I bet that cute little cunt of yours is just dying for something inside it."
"Oh Mommy, it really is!" exclaimed Lilly. "Just feel and see how juicy it's getting!"
Karol already had her spreadeagled and was tenderly playing with the delicate lips of her hairless little snatch. "I'm gonna do better than just feel it, sweety," Karol assured her.
She pushed her face down the porcelain-smooth columns of her slender thighs and nuzzled her nose and mouth against her young daughter's fresh, tender sex-flesh.
"Ooooo!" cried Lilly, loving the feel of her mother's practiced lips and tongue.
Curt and Kelly were heaving and grunting like a couple of pigs snouting for truffles. They gave a loud wheeze and then Kelly began making funny noises in the back of her throat.
"Listen, Mommy," directed Lilly, "Kelly's getting her cookies off! Oh wow, it makes my cunny hot as heck to know Dad's over there fucking my big sis while you're eating me out!"
Karol was now getting a cunt full of love juice in her own hot hole. Wonder if the kid'll give her Mom a mouth job, Karol thought feverishly to herself. She shifted around so that her snatch was directly over Lilly's face, never for one moment taking her lips away from the youngster's sweating slit.
To her delight, Lilly frigged her by hand for a few seconds, then went right on into the wet hole with her tongue. She didn't even have to be coaxed. Oh shit, Karol thought, it's so sweet to have her little mouth on me I'm about to pop my cork any second now.
Lilly was opening and closing her legs against her mom's ears, savoring every second of the wonderful tongue job. She felt her pussy quiver and knew she was darned close to coming off. She opened her mouth to let out a little cry of pleasure, but pussy juice from Karol's steaming cunt promptly filled it. She gulped it, smacked her lips, then pushed her tongue back inside for more. Her tight little slit was on fire now and her ass was shaking like crazy.
Karol hit it first, jerking her cunt in wild abandon against the hungry lips of her pussy-sucking daughter. She gave a long moan, keeping her mouth tightly plastered to Lilly's cunt, and the kid could feel the vibrations from her voice all the way up to her tautly-bouncing titties. She began whimpering. Karol frantically massaged her titties and kept her tongue moving like a butterfly. Lilly gave a sharp yelp, jammed her ass back and forth in one last burst of energy, and came off with a wet, heated thrill that left her breathless.
As the two lay recuperating from their torrid session, they became aware of Kelly and Curt close by. They had magazines in their hands and were fanning their hot, sweaty bodies for them.
