Kelly dropped her open mouth on her younger sister's pouting fruits and moved her lips on the taut points in a gentle, sucking motion. She went from one to the other like a butterfly. Lilly loved it. It was different than when her dad did it -- sort of lighter and softer. That made her think of him again for a different reason. She knew he'd be in there before long, at least that's what he had told her. She didn't understand just why it was but he'd told her to just go along with whatever he did and she was all set to do just that.
Maybe he wants to just watch Kelly and me naked together, she thought to herself.
But she couldn't keep her mind on things like that -- not with her big sister's mouth going to work on her the way it was! Kelly licked her hard little nipples till they felt nearly ready to burst and Lilly began twisting around.
"Getting a little warm in a certain place, sweety?" she teased, applying friction on her pussy with the hairy mound of her own cunt. She grinned conspiratorially and said, "Don't worry, I know just how you feel. This little pussy of yours is needing some love awful bad about now, isn't it?"
She started to draw her mouth down the flat expanse of Lilly's tummy toward her damp, smooth-skinned organs but Lilly stopped her.
"Wait, Kelly," she entreated. "Please. Can I just... can I..." -- her face was red with embarrassment but she finally got the words out -- "can I just see what it feels like to have yours in my mouth for a sec? Jeez, they look so big and yummy."
She raised her mouth and Kelly gladly scooted up to where she could secure a nice mouthful. She supported herself on her elbows and let Lilly lick the fat tips of her tits, swinging the firm flesh back and forth to let her get a taste of each one. The kid gobbled them up like a pro. Seeing her little sis so ravenous for a tit in her mouth sent a pulse of passion through the hot meat of her busy cunt.
"Oh wow, sweety," she gasped, her nipples red and tingling, "you're too much, you know it? You're going to make me cream off! Lemmee fix you up too."
First she remained in position over Lilly's body, removing her tits and swinging them slowly over her face as she ground her cunt flesh into the hairless swell of Lilly's little pussy. Then gradually she scooted backwards till she was able use her hands at the same time. Now her knockers were out of reach of Lilly's mouth, but the sweet heat she was pouring onto her pussy was well worth it. With one hand she alternately tweaked Lilly's nipples, all the while rubbing her own hairy snatch against it. The two girls were both getting so excited they were sweating all up and down the lengths of their warm bodies.
"Whew," breathed Lilly, "I didn't even know girls could... ungh... do each other like this but you're... ungh... ahhh... you're gonna make me come if you keep... oh."
"That's just what I intend to do," Kelly broke in. "And I'll be right in there with you getting myself off too. Seeing you get so darned hot makes me the same way, you know. You've got a real cute little shape, sweety... you're lucky to be using all that good stuff up the way it should be, too -- I was a lot older than you before I ever got my cookies any other way except by my own hand."
Kelly suddenly turned onto her side and scissored Lilly's legs between hers, hunching slowly and rhythmically. Now their tits were meshed and their cunts were rubbing together like mounds of soft leather. Kelly fingered the sweet, moist surfaces of her little sister's pussy too, working her hand in unobtrusively between their sliding young pussies. She searched for the kid's clit and began stroking it delicately with her thumb and forefinger.
"How's that make your little love button feel, sweety, huh?" she rasped. Her voice was thick with passion and the sound of it in Lilly's ears seemed naughty and dirty to her, yet also supremely exciting.
But Lilly's ears weren't the only ones hearing Kelly's impassioned words. Curt had been crouching outside the door with his ear plastered to it for several minutes. He had meant to rush in on them before things got this far along but the stimulation of listening to his two daughters naked together made him hold off. He couldn't see them but their love noises and the words they exchanged from time to time were more than enough to raise a stiff hard-on.
He even had his cock in his hand and was frigging it a little in spite of himself. He knew it was stupid to get wound up in a sex trap of his own at a time like this but eavesdropping on the pair had got him so horny he couldn't help it. Finally he got control of himself.
"God damn it," he hissed between his teeth, "I got to quit this shit and get on with my plan to run in on them and then get Karol down here to see what her sweet little daughters are doing."
Just as he was stuffing his cock back into his robe he heard a series of little squeals. One of them was obviously in the midst of her climax. He waited only a few seconds, then burst into the room.
Lilly was lying on her side with her legs snuggled between her sister's and her shiny little cunt rubbing against Kelly's a mile a minute. Her mouth was open and her eyes were closed tight. The expression on her face would have been enough alone for him to tell that the kid was getting her jollies. Kelly was humping to beat the band and jiggling one hand in the kid's twat and the other in her own.
At the sound of him bursting into the room she jerked her head and a look of terror crossed her face. That was quickly replaced by an expression of stormy anger. Lilly was already into her climax so she wasn't as bothered by Curt's sudden presence as Kelly, who had not quite hit the top yet. Worse still, she was at that maddening point where the interruption made her so frustrated it almost actually pained her.
"Well isn't this a pretty sight?" he snidely growled. "A man comes down to the kitchen to get a drink and finds his grown daughter just flat-out raping her little kid sister!"
Lilly's ass was still in the throes of quick, wrenching spasms from her orgasm. As he spoke, she jerked her eyes open and saw him. She was so ashamed at having him see her that way -- even though she knew he was going to visit sometime -- that her face turned bright red. The worst part was that she had to keep pumping her ass several strokes after she knew he was there -- she just couldn't help herself.
"What th..." Kelly began, furious at his invasion and made even angrier by his accusation.
But he broke in. "You slut, you," he exclaimed. "Putting your filthy hands on an innocent kid that age and making her let you do what you want with her poor, naked little body. I think your mother's gonna have to see this!"
And he turned and bolted up the stairs, leaving the girls speechless. Lilly had been warned to go along with him and do whatever he said, so she wasn't about to say anything to Kelly about the real facts. Kelly was sputtering.
"Hummmmph!" she cried, her eyes flashing. "Bringing Mom down here, huh? Well, just let him bring her -- there just might be a surprise or two before this is over!"
Lilly was very puzzled by that. It seemed obvious to her that their mom would be just as outraged at the scene as their dad had appeared. She cocked her head and started to ask a question but Kelly shushed her and tossed her nighty and panties to her and said she better get into them. Then she started putting her own back on. Before either one of the girls were through, Curt came dashing back with their mother in tow. He flung open the door and bellowed, "There she is, Karol. Just like I told you she was. It's a hell of a thing for you to have to see, but I thought you ought to. Can you imagine a girl stooping to that level -- taking advantage of her own kid sister and making her strip naked and get in bed with her? Honey, our little Lilly's barely old enough to be out of diapers and yet look what Kelly's forced her into!"
