Laura and Marty agreed that she would sneak through the house and into his room late that night. Laura's room was too close to his parents' room. She and Marty would still have to worry about his sister, Jolene, but Marty's room seemed a safer place than Laura's.
Laura waited until well after midnight. Marty's sister and his parents had all gone to bed over an hour before. Laura had a wild urge to go naked as she crept through the house, but she decided to wear her robe. That way, if someone spotted her, she could casually offer some believable excuse. If she were naked, no excuse would be believable.
Creeping out of her room, she held her breath and listened before she started gliding, slowly and silently, through the big L-shaped house. The house was dark except for shafts of moonlight that came in through windows where the curtains had not been closed. She tingled in anticipation of having Marty's huge cock in her again.
Still, as she approached Jolene's room, Laura slowed down and paused to listen between each step. Jolene's door was cracked open only about an inch and there was no sign of light inside, but Laura thought it best to be cautious. Hell, suppose Jolene had somehow heard something and was peeping out through that one-inch crack?
Laura was almost even with Jolene's door when she heard a low gasp. Stopping cold, Laura stared at the door, expecting that it would be jerked open and that Jolene would burst out.
But nothing happened. Nothing, that is, except that another low gasp came from inside the room. And Laura realized then that neither gasp had come from near the door. She also realized that they had not sounded quite like gasps of surprise.
They had sounded more like gasps of pleasure.
Laura wondered what was going on in there. Surely Marty was not in there sticking his prick into Jolene. Perhaps the girl had sneaked a boyfriend into the house.
Another low gasp came from inside the room, then a soft moan.
Possessed by her curiosity about everything sexual, Laura crept up to the door and silently and very slowly pushed it open another two inches. She could see Jolene's double bed, bathed in shafts of moonlight streaming in through the bedroom's windows.
Naked, Jolene was on the bed. She was lying on her back, her shapely legs spread wide and bent sharply at the knees. Slowly, she pulled a massive dildo almost all the way out of her young cunt, and then, holding the handle that was attached to the base, she fucked all of the rubber prick back into her pussy as she arched her back and ass up off the bed. She gave that low gasp again, then twisted the dildo around in her cunt, and she moaned.
Laura could barely hear the sensual sounds.
As she watched Jolene sink back down onto the bed and then repeat the entire sequence of lewd motions several times, Laura's nipples, clit, and cunt lips swelled with lust. And she was struck by a surprising thought. She had had sex with four nephews. So why not a niece, too? And Laura had never had sex with a female. She wondered what it would be like.
Laura eased away from Jolene's door and on to the end of the hall to Marty's room. His door was open a few inches and she opened it wider, slipped inside, and quietly closed it.
Marty grabbed her from behind, one hand across her mouth, his other arm around her waist. He pulled her against him and she didn't struggle or make any noise. Untying her robe, he began rubbing her dripping pussy lips.
"I've always wanted to grab somebody that way in the dark," Marty whispered with a chuckle. He took his hand away from her mouth. "But I had to make sure you wouldn't yell."
"It was fun, but only because I knew it had to be you," Laura whispered. "How would you like to stick that great big prick of yours into your sister?"
Marty gasped. "Are you serious?"
"Yes." Hurriedly, she told him what she had seen, and what she wanted them to do. Through her robe, she felt Marty's immense cock stiffening against her ass.
"Let's do it!" he whispered. He took her robe off, leaving her naked. He was already naked.
They crept out of his room and down the hall to Jolene's door. By the time they got there, Marty's prick was rock hard. They peeped into the room.
The gorgeous teenaged blonde was still on her bed, and the long thick dildo was still in her cunt. She was moving a bit faster as she fucked herself, but the pattern of her movements was still the same. In the moonlight, the dildo and her cunt lips were glistening with pussy juice, and more juice rolled out of her cunt every time she rammed the rubber prick into herself.
The hand that wasn't working the dildo had been clutching and twisting the bedcovers, but now she moved that hand to her huge tits and started kneading them. She wrenched one of her tits each time she fucked the dildo into her juicy cunt.
"Jesus!" Marty breathed as his sister slammed the dildo into her pussy.
There was no danger that Jolene had heard him. Laura had only scarcely heard him, and her ear was just inches from his mouth. He began squeezing and rubbing Laura's tits softly and Laura began caressing his stiff cock while they stood and watched Jolene knead and wrench her own tits and fuck her own cunt with the dildo that was glistening with her abundant pussy juice.
Bit by bit, Jolene moved faster and her gasps and moans got louder. For a few seconds she let go of her tits and yanked at the bedspread. After stuffing a wad of the bedspread into her mouth, apparently to stifle her sounds, she started kneading and wrenching her tits again as she fucked the rubber prick in and out of her cunt. But the sounds of her gasps and moans kept getting louder.
"Now!" Laura whispered, in a voice as quiet as Marty had spoken in several minutes before.
The two of them dropped to their knees. Very slowly, Laura pushed the door farther open. It moved soundlessly.
Jolene's sounds and motions were becoming increasingly frantic as she fucked herself. Laura and Marty hardly breathed as they slowly crawled into the room on their hands and knees. What little noise they made was covered by Jolene's louder noises. When they were almost halfway to the bed, they stood up.
Then they sprang.
Jolene saw them in the moonlight before they reached her, and her eyes widened in surprise and fear, but they moved too quickly for her to cry out. Laura leaped onto the bed and clamped a hand over Jolene's mouth. As Marty dived onto the bed and grabbed for Jolene's legs, the girl pressed her legs tightly together and rolled onto her side as if she were trying to escape.
"Easy, Jolene!" Laura whispered soothingly. "You've been having fun. We just want to help you."
"Mm-mmm!" Jolene moaned in protest.
But at his sister's feet, Marty came up to his knees. His colossal hard prick pointed straight at her, and it jumped slightly with its steady throbbing. Jolene gazed fixedly at his cock.
"Wouldn't you like to have some of this, little sister?" Marty breathed. Slowly, he stroked his colossal cock. Keeping one hand over Jolene's mouth, Laura gently kneaded the girl's massive tits with her other hand.
Jolene kept gazing at her brother's prick as he stroked it. And very slowly she rolled onto her back. Even more slowly, almost as if it were against her will, she spread her legs wide. Her already-fast breathing quickened.
"Mmmm!" she moaned, but this time it was a moan of lust.
"Good girl," Laura whispered. She kissed and licked one of Jolene's turgid brown nipples.
Marty smiled and moved forward on his knees, between his sister's widely parted legs. Jolene took the dildo out of her cunt and tossed the rubber prick aside. But her feverish gaze never left her brother's prick. Her thighs and belly quivered. Laura took her hand off the young blonde's mouth.
"Like a dog!" Jolene whispered urgently. "Fuck me like a dog, big brother! Maybe that way I'll be able to take your whole cock! God, you're so fucking big!"
"Any way you want it, baby," Marty said with a grin as he proudly stroked his iron-hard prick.
Jolene pulled her legs up, rolled over, and came up onto her hands and knees. "Hurry, Marty, I need it!" she panted.
"I'm hurrying!" Marty answered as he fitted his bulging cockhead between her slippery pussy lips.
Laura watched from the side as he grasped his sister's hips and began fucking his massive prick slowly into the girl's tight cunt.
"Ooooo! You're stretching the shit out of me – but I love it!" Jolene moaned. "Give me all your prick, Marty!"
"Honey," Marty whispered as he kept pushing his cock into her burning pussy, "nobody can take…"
"Bullshit!" Laura snapped, reaching down to massage one of the girl's hanging tits. "I took your whole damned prick this morning, and I don't imagine you've forgotten! Maybe your slut of a little sister can take it all, too. Keep pushing it in! Fill her pussy with your huge prick!"
"Yyeess, fill me with it!" Jolene whined, and to help him fill her with cockmeat, she started shoving her hips slowly backward.
Laura kept massaging one of Jolene's tits and watching more and more of Marty's cock disappear into the girl's cunt. When all but two or three inches of his great prick was inside her pussy, the slow pace became even slower, and Laura knew that the inner end of Jolene's young pussy was being stretched now.
"Uunngghh! Push!" Jolene grunted, gritting her teeth. "I can take it! I know I can!"
Laura grasped Jolene's other tit and began kneading both of the blonde's heavy tits. And Jolene shoved her hips back hard and suddenly finished fucking her red-hot cunt onto her brother's pulsating prick.
"All riiight!" Laura cried, pumping her niece's tits wildly. "You did it, Jolene!"
"I almost split myself open, too!" Jolene breathed. "Jesus, what a prick! Keep it all the way in me for a minute, Marty, so I can get used to it!" And then she snapped her pussy around his cock.
"Christ!" Marty gasped. "She's just like you, Aunt Laura! Another snapping pussy!"
"Good for her!" Laura whispered.
She let go of Jolene's tits, went over and closed the door, and came back and climbed onto the bed again. Marty had moved his hands to Jolene's tits and was squeezing her tits deeply. Spreading her legs extra wide, Laura lay down with her loins almost under Jolene's head.
"Ever sucked a cunt before?" Laura asked, and she worked her crotch muscles and made her wet cunt gape open.
"What a gorgeous sight!" Jolene squealed, dropping onto her elbows to bring her head down to her aunt's sultry pussy. "No, I've never sucked a cunt – but I'm about to suck one!" She pressed her mouth against Laura's slick pussy lips and fucked her tongue as far as it would go into Laura's snug cunt.
"Aaahhh! That's it, honey!" Laura moaned delightedly.
As she took hold of Jolene's head, the blonde's tongue began writhing around in her pussy and fucking and out at the same time. Pleasure flooded through Laura, and she kept moaning happily.
"Now fuck me, big brother! Fuck the shit out of me!" Jolene cried.
She pulled her hips forward as Marty drew his hips back. He stopped when only about an inch of his great cocklance was still in her cunt.
Kneading her tits even more deeply, he fucked his prick all the way back into his sister's sweet cunt. Although his fuck-thrust was slow, it was considerably faster than his previous fuck-thrust had been. Jolene had pushed herself back to meet him, and now she snapped her pussy around his cock again and wiggled her hips gleefully.
"Ooohhh, I love your great big prick, you sister-fucking bastard!" the girl cried.
"He's also an aunt-fucking bastard!" Laura chuckled. Then she sighed and moaned as Jolene's tongue began fucking in and out of her searing pussy again.
Marty and Jolene were pumping their hips slowly but steadily, creating sensual pleasure as his cock fucked in and out of the girl's sopping cunt. Jolene began working her loin muscles almost constantly, snapping her pussy lightly at his fucking prick. Marty started rotating his hips to put more action on his cock's fuck-strokes, and Jolene began grinding her hips in the opposite direction.
"Mmmm! Ooooo!" the blonde groaned.
She dragged her tongue from the bottom to the top of Laura's pussy lips repeatedly, lapping up some of Laura's flowing cunt juice. After smacking her lips obscenely, the girl started darting her hot tongue at Laura's distended clit.
"Aahh! Aaaiiiii! Yyeess, do me!" Laura whimpered.
She writhed with joy as Jolene's tongue kept jabbing her clit. Jolene's hands were between Laura's spread thighs, and the blonde began rubbing Laura's cunt lips with her fingers. Then she began whipping her tongue back and forth across Laura's clit and at the same time she fucked two fingers into Laura's seething pussy. She found Laura's G-spot immediately and started massaging it, and Laura's writhing got stronger as her pleasure rocketed.
"Oooh, Goddamn, yyeeesss, you're doing it just right!" Laura wailed. "I'm gonna turn, baby!"
"You and me both, Auntie! Aannhh, ooohhhh!" Jolene cried.
Laura's cunt quaked with orgasm, and pussy juice gushed out inside her. She wriggled madly, and her hands jumped to her mountainous tits and started squeezing them convulsively.
When Jolene shoved her pussy back to meet her brother's next cock-thrust, she was cumming, too, and as Marty drew his cock back, she held her hips where they were and waggled them feverishly, wiggling her twitching cunt around on his retreating prick. And since she didn't move her hips forward, not as much of his prick slid out of her as before, and when he fucked into her again, she was already waiting for him and was still waggling her hips in delight.
"Aawwnnhh, Jesus, my little sister's running wild and so's my big auntie!" Marty crowed as he kept fucking his cock in and out of Jolene's sweet pussy, revolving his lean hips as he pumped them.
The excitement of the two sluts seemed to be contagious, and the boy started squeezing his sister's tits faster and fucking his huge prick in her cunt faster.
"Aaahhh, uunngghh!" Jolene whimpered, and she began pumping and grinding her hips again, in time with her brother's fuck-strokes.
At the same time, she speeded up the two fingers she had inside her aunt's white-hot cunt, rubbing Laura's G-spot faster but rubbing it delicately, letting her fingers skate along on the super-sensitive flesh. The blonde's fiery tongue was still whipping from side to side across Laura's clit, but now the girl changed the pattern and added some up-and-down swipes with her tongue across the turgid clit.
"Uunnhh! Ohhh, yyeess, dear sweet unholy God!" Laura babbled as her lewd bliss became even more intense. "Uuunnnhhh, yyyeeeesss!"
Another orgasm began chopping through the woman's voluptuous body, and she bounced up and down with each shaking contraction of her juicy pussy. She clawed at her enormous tits and stretched them straight up as far as she could and then pounded them back down with her fists and groaned deliriously with the pain-pleasure.
"Aannhh! Aaannnhhh! Cumming!" Laura cried.
"Ooohh, sheeit, Sis, you're really to our auntie!" Marty raved.
"And you're doin' it to me, big brother!" Jolene squealed. "Aaaiiieeeee! I'm makin' it!"
Her pussy was convulsing again but she kept working her hips this time, moving them even faster. Marty kept pace with her fuck-strokes, and since he was still fucking his whole cock into her sweltering cunt on every thrust, his cockhead was slapping hard against the inner end of her cunt flow.
"Uunngghh, uunngghh, oohh, damn, fuck me, brother!" Jolene grunted. She swirled her tongue around and around madly, all over Laura's straining clit, and kept rapidly but lightly rubbing the G-spot inside Laura's overheated cunt.
"Aaaaggghhh!" Laura wailed. "I'm gonna cum again!" She clenched her tits insanely and squirmed and bounced like a crazy woman as her orgasm jolted through her.
"Aaaaiiiiii! We're still right together, Auntie, because I'm gonna cum again, too!" Jolene howled. And as she stepped up the pace of her pumping and grinding hips, Marty kept matching her stroke for vigorous stroke, fucking his awesome prick into her sizzling cunt.
"Hell, yes, and I'm joining the club!" he cried as his prick heaved. "Take my jism, little sister!" And his cum began spurting into Jolene's hot cunt.
