The following day found the entire family out by the pool. It was a hot day and they had long ago discarded their bathing suits. As they skinny-dipped, they found excuses to brush up against each other, fondling a tit here, a cock there.
Their watery sexual play turned them all on and, gradually, they began kissing and hugging each other, breaking off into natural pairs.
Soon, Aunt Laura and her son, Gary, wandered off into the house where they could be more comfortable in one of the bedrooms. Next, Uncle Richard and his niece, Karen, walked off into the grove of trees near the pool.
That left just Holly and her brother, Jeff. The girl giggled self-consciously and blushed as she saw her brother looking at her meaningfully.
"Hey, look, Holly!" the teen said. "Karen and Uncle Rich must really be going at it!"
"What do you mean?"
"Well, look! You can see the bushes shaking like crazy!"
Holly looked and saw that her brother was right. She blushed again and they both laughed.
Jeff swam over to his sister and stroked her big tits through the cool, green water of the pool. "Hey, what are we waiting for, Sis?"
"What do you wean?" she asked coyly, even though she knew exactly what he meant.
Jeff laughed. "Oh, come on, cut the crap. I saw you and Uncle Rich out here the other day."
Holly gasped. "You did?"
"Yeah, I did. So don't play the virgin with me. I know that he popped your sweet little cherry. And you remember what you told me, don't you?"
"What did I tell you?"
"That once he fucked you, it would be my turn!" Jeff made a grab for the girl but, laughing delightedly, she swam quickly away and clambered out of the pool.
Jeff chased her and caught up with her on the lawn right about where their uncle had fucked her. He tackled her, sending her sprawling onto the ground. He threw his body on top of hers and pressed his mouth against hers.
Moaning with desire, the girl no longer fought her brother. She returned his kiss, fucking his tongue with hers, their saliva mingling.
"Mmmmm, Jeff," she murmured as they broke their kiss.
"So, what's it to be?" Jeff asked, stroking her tits.
"What's what to be?" she asked, confused.
"You're not gonna make me wait any longer. I've been hot for your body for a long time now. I'm gonna fuck you, just like you promised."
"Oooh, Jeff…" The girl was growing more and more excited with his every word.
"So…" he continued, "the only question remaining is how we should do it. How do you wanna fuck?"
"Can we fuck with me on top, Jeffy?" she asked shyly.
The teen grinned broadly. "You sure as fuckin' hell can, baby!" he laughed, rubbing her big tits harder as he felt his big cock harden in anticipation.
Jeff lay down on his back and his little sister eagerly squatted over his hard, muscular body, her little juicy cunt mere inches from his throbbing nine-inch hard-on. Sighing happily, she reached down and grabbed his big prick with both hands while slowly lowering herself over him.
The beautiful blonde fitted the large, throbbing cockhead right up against her hot, tight cuntslit, spreading her knees wide at the same time.
Jeff moaned and stared up at his lovely sister as though he were mesmerized. God, but his sexy little sister was such a turn-on, he could hardly stand it! He saw her eyes glaze over with a hot, lewd look of fuck-lust as she worked his wide cockhead more firmly between her cuntlips. Her pussy held his prick so tightly he had all he could do not to shoot off right then and there!
Suddenly, with a broad grin at her brother, Holly jammed her small, tight cunt down hard on Jeff's big, throbbing cock. He jerked with shock and lust as he felt his prick plunging deeply into the girl's wet cunthole.
Holly threw her head back and groaned. She had never felt anything so delicious in all her life as her brother's big cock completely filling her pussyhole with nine rigid inches of hot cock-meat.
She sank farther down on his stiff cock until her swollen pussylips were crushing the base of his cock. At last, she had her brother's cock all the way in her pussy!
"That's it, baby! Now, fuck me! Fuck your big brother, Holly!" Jeff yelled.
"Ohhh, yesss, Jeffy, I'll fuck you! I have to fuck you! I'll fuck your brains out till you pour your sweet cum up my pussyhole!" Holly shouted, her lust-glazed eyes rolling back in her head. Her pussy felt so exquisitely full with her brother's nine beautiful inches of hot, throbbing prick. She had never felt so good or hot or excited in her life!
"Mmmmmmm, your cock is the best ever, Jeffy! It feels soooo good in my cunt! I just love it!" the girl groaned.
She continued to work her cunt up and down her brother's big cock-shaft. She raised herself almost completely off his cock, then she lowered herself again until it was completely buried in her hot quivering pussy. Over and over, she fucked herself with her big brother's prick, feeling her orgasm growing.
Her pussy gushed out a flood of hot pussyjuice which oozed out her flowing cunt and trickled down her legs. Her brother's cock was slick with her fuck-juices as she continued to pump his big prick in and out of her tight pussyhole.
"Ohhh, yeah, baby, you're doin' great!" Jeff yelled as he reached up and pinched her big, throbbing nipples, making them even harder and more pointy.
By now, Holly was humping up and down on Jeff's cock like a smoothly oiled fucking machine. As she fucked her cunt downward, Jeff lifted his ass up off the ground and slammed his crotch against hers.
Holly clenched and unclenched her cunt muscles as hard as she could, hugging her brother's prick to her cunt tightly, thrilling them both more and more.
"Oh, Jeff, fuck me, fuck me!" Holly cried, rapidly shoving his huge cock in and out of her twitching pussyhole.
"Yeah, Holly! Fuck my cock! Ram that hot little pussy of yours over my prick!" Jeff yelled, humping his ass even higher off the ground, grinding his crotch against hers harder and harder with each fuck-thrust.
His cock twitched and burned inside his little sister's hot pussymeat, about to come. Her cunt slammed up and down on his cock, fucking him over and over, more and more brutally with each cunt-thrust of her crotch.
The teen's balls began to tighten and he groaned aloud, jerking his ass off the ground savagely, digging his fingers into the girl's tits as he humped back against her fucking thrusts.
With each downward fuck-thrust of her tight cunt, he shoved his bursting prickshaft up into her pussy. Finally his hot cum blasted into her wet pussy, spurting into her tight little pussyhole in thick, creamy spasms.
Holly all but lost her mind when she felt her brother's scalding blasts of jism deep inside her cunt. It was better than she had expected, and she loved it.
And it made her come hard. Her stiff clit pulsed hotly against her brother's spurting cock, which was still pistoning inside her pussy as she came. Gallons of hot pussyjuice poured from her cunt and flooded his cock, mingling with his thick cum.
As Holly and Jeff continued to come, they pressed their lips together and mashed their tongues against each other, tongue-fucking each other's mouth over and over. The air around them was filled with the musky odor of cum and pussyjuice, just turning the two teenagers on all the more, prolonging their orgasms.
The instant the girl's climax ended, she slipped her juicy cunt off Jeff's jerking cock and, throwing herself down across his thighs, she eagerly sucked his prick into her mouth, licking all the cum from his still-hard cock.
"Oh yes, baby! Suck it! Suck my cock!" Jeff called out, still humping his ass off the ground, this time feeding his cock to her hungry mouth.
Moaning with excitement, the blonde ran her hot, wet mouth over his entire prick while he squirmed around on the ground, trying not to come again too fast. She sucked his cock in as hard and far as she could, nibbling on the sides of the pulsating cock-meat.
"Suck harder, cunt! Suck me till I come!" Jeff ordered.
His words turned the girl on all the more and she sucked more and more of her brother's prick down her throat. While she sucked him off, he ran his hands all over her beautiful, lily-white ass and as much of her titflesh as he could reach.
Holly felt Jeff's prick strike the back of her throat, and she began to deep-throat him. She swallowed hard, feeling his satiny cockhead slide easily down her throat. She sucked and sucked and swallowed hard, forcing even more of hot throbbing cock down her throat. She couldn't wait to feel his cum filling her mouth and shooting into her hungry belly.
When she had swallowed so much of her brother's cock that her nose was pressing against his nuts and her mouth was brushing his curly prick hairs, she began to tense, then relax her throat muscles, giving Jeff the best head possible.
"Ohhhhhh, Holly! That feels terrific! So good! What a great little sucking mouth you have! Feels almost as hot as your cunt!" Jeff cried, still rubbing her ass and tits as he continued to hump his ass off the ground.
Holly continued to suck hard on her big brother's cock, deep-throating him expertly. She clenched and unclenched her strong throat muscles around his big prick. She loved the feel of his wandering hands on her trembling ass and heaving tits. It just excited her more, making her suck him off even harder and faster.
Jeff's prick twitched and jerked and he knew he was about to come. He could feel his sister's throat muscles working brutally on his savagely pumping shaft, trying to milk the cream from his cock.
Holly was making loud wet, slurping sounds as she sucked on her brother's cock, and the noise turned them both on more than they would have thought possible. And knowing that, while Holly sucked her brother off, their uncle was fucking their sister, and their aunt was fucking their cousin, just made them hotter and hotter.
"Suck it, baby!" Jeff cried, half out of his mind with lust. "Suck that cock!"
Holly felt her brother's prick jerk violently and she continued to work her throat muscles around it, clenching, then unclenching, urging him silently to come.
As Holly continued to suck his cock, she swirled her tongue around it as her head bobbed up and down, faster and faster as both of the teens neared their orgasms.
Jeff groaned a long mournful sound and moved his hips frantically, humping his ass up more and more violently from the ground, needing to come. He couldn't wait to pump his huge load of cum into his horny little sister's waiting mouth.
"Ohhhhhh, Holly… Holly…" he chanted as she cupped his heavy, churning balls, rotating them in her palm.
She was sucking her brother's big cock faster and faster now, feeling it bounce off the roof of her mouth, stabbing into her throat deeper and deeper as it sought more depth and heat. His grunts and groans and squeals of joy were music to her ears as her pussy oozed out more and more of her hot cream.
"Ohhhhh, Holly, that's soooo fuckin' good! Suck me off, Holly! Make me come! Suck meeeee!" he shouted, his handsome face contorted with passion and lust as he strained for release.
He fucked his sister's mouth, pumping his prick hard and fast in and out of her mouth. The girl was overcome with a hot, raging lust as her brother's prick swelled even bigger in her eagerly sucking mouth. Her hot cuntjuice overflowed her pussy and began trickling down her legs. She longed to feel her brother's cum filling her entire mouth.
"I'm almost there, Holly! Suck me haaard! Eat me, Holly!" the teen yelled.
His cock thrust upward, pushing her mouth down tighter over his aching prick. She sucked harder and deeper on his cock-shaft as he moaned over and over. She massaged the teen's balls and bit the fleshy part of his aching prick.
"Ohhhhh, that's soooo great!" Jeff yelled as he dug his fingers into her hair, pushing her mouth down even farther over his cock. His entire body tensed as his prick exploded in his little sister's mouth. "Coooommmmiiiiinnnnggg!"
The long-awaited white cum exploded from his cockhead, shooting in a gusher into the girl's sucking mouth. Another thick, hot gusher of jism shot down her throat and splashed into her belly, filling Holly with a thrilling pleasure as her own orgasm began.
Spurt after spurt of jism shot into her mouth, slid warmly down her throat, and spilled into her tummy. At the same time her pussy spasmed in orgasm, sending wave after wave of raw, hot, forbidden ecstasy washing over the girl.
She tore herself away from her brother's jerking prick and threw herself back onto the ground, her hands clawing at her pussy as she continued to come.
Jeff grinned, watching her, and stuck two fingers of his right hand up her aching cunthole. He could feel her pussy muscles immediately clasping themselves around his fingers and his cock stiffened again with desire.
"Just think," Jeff panted, still fingerfucking his sister's orgasming pussy, "if we've already had this much fun with Aunt Laura and Uncle Rich as chaperones, just think what lies ahead for us, Sis!"
Her brother's words intensified her orgasm to such an extent that the girl fixed her eyes on him for a second, moaned loudly, and passed out, a smile of fulfillment on her beautiful face.
