Chapter 4

Not long after Judy had crept to her brother's room, Cindy opened her bedroom door and looked carefully up and down the hall. Seeing and hearing nobody, the petite brunette teenager sneaked quietly out of her room and into the room where her brother Donny was sleeping. She found him sitting in bed reading a girlie magazine. Donny reddened and quickly slipped the magazine under his mattress.

"Cindy, what are you doing here?" he demand- ed. "You should be asleep by now."

"Oh, don't be such a sourpuss," Cindy said as she approached the bed. "I just got lonely, that's all. I wanted somebody to talk to."

"Oh, all right," Donny said, "what do you want to talk about, Sis?"

Cindy grinned and crawled into bed beside him. "I wanted to talk about what we did today," she said. "Wasn't it fun?"

"Yeah, it was fun," Donny said dryly, "but you didn't have to crawl into my bed to tell me that."

"It's cold," Cindy said. "Anyhow, don't you think Judy and Jimmy are really okay?"

"I sure do," Donny sighed. "Man, that Judy really turns me on."

"What about me?" Cindy pouted. "Don't I turn you on?"

"Are you kidding?" Donny laughed. "You're just my sister."

Cindy bit her lip, stifling an angry reply. She felt really horny and was hoping her brother would help her out, but he didn't seem to regard her as anything but his kid sister, not worth his attention. Well, she'd just have to be persistent-and use a few tricks to get his attention. Without warning she tugged off her nightgown and tossed it on the floor.

Donny gawked. He'd been so wrapped up in his cousin Judy that afternoon, he hadn't really looked at his sister, even though he'd never seen her naked before. Now he looked. She was uncovered from the waist up, and he ogled her cute little apple-size tits and dainty rosy-red nipples. He had to admit that she had very nice tits. He felt a horny stirring in his balls-then reminded himself that a guy wasn't supposed to feel that way about his own sister.

"What'd you do that for?" he said uneasily. "You just said you were cold."

"I wanted you to see my tits," Cindy said frankly. "Don't you think they're just as nice as Judy's?"

"Uh, yeah, sure," Donny said, "I guess so." "Wouldn't you like to play with them?" she said.

"Aw, come on, Sis, cut it out," Donny said. "I'm your brother, for chrissake."

"That doesn't matter," Cindy purred. "It'll still feel nice."

She seized Donny's hands and clamped them down around her pert naked tits. Donny felt the silky little globes pushing against his palms. They were firm, hot and throbbing, really fun to touch. Cindy let go of his hands, and he kept them there, unable to resist the temptation. Reading that girlie magazine had gotten him pretty excited.

"There," Cindy cooed, "isn't that nice?"

Donny didn't answer. At that very moment his sister's nipples were going stiff against his palms, pushing lustily outward and throbbing powerfully. He sighed and squeezed her tits, and her small red nipples got completely hard and pointed. He squeezed again, and Cindy gave a little moan of lusty excitement.

"Ummmmm, Donny, that feels nice," she sighed.

She reached out and started unbuttoning his pajama top. Donny fondled and molded her pretty little tits, getting more aroused by the second. Judy and Jimmy had made out together, by their own admission, even though they were brother and sister. Maybe it wasn't so wrong after all. And they sure as hell had to do something for entertainment, being stuck on this damned island for the whole summer.

Cindy drew off Donny's pajama top and admired his lean, tan, hairless chest. She'd always thought her brother was sexy, and this afternoon, when she'd seen him naked for the very first time, she'd wanted very much to touch him. Now was her chance. She ran her hot little hands over his shoulders and chest, and he sighed and squeezed her tits harder. That felt very good to Cindy. The pleasure seemed to seep right down her body and into her pussy.

"You liked all that stuff you were doing with Judy, didn't you?" she said huskily.

"I sure did," Donny sighed. "Man, that was the most fun I've ever had."

"Well, you and I can do it, too, Donny," she said. "We can have fun, just like Jimmy and Judy do."

Donny saw no reason to resist. Nobody would ever know what they did. Their parents were far away, and Captain and Mrs. Cooper were sound asleep in their room upstairs. Today's games with Jimmy and Judy had whetted his appetite for discovering more about sex. He slipped the bedclothes down, uncovering himself and his sister. He still had his pajama bottoms on, but Cindy was completely naked.

He stared at the base of her belly, that cute little puff of springy brown curls. He just couldn't get over how different girls looked, how pretty. He reached down and petted the warm soft fur of her muff, and Cindy sighed happily and let her legs fall open. Donny ogled the moist red flesh of her gash and its delicate fringe of brown curls.

"Go ahead, Donny," she said eagerly, "touch my pussy."

Donny slid his hand lower, cupping her searing hot slit. Cindy felt instant excitement, and her pussy began to puff up and get even hotter. Her virgin cunt began to dribble warm sticky juice into her brother's palm. Donny smeared the syrupy stuff all over her tender red gash, and pleasure rippled through her belly. She remembered all the delicious things Jimmy had done to her that afternoon, and she wriggled with lusty impatience.

"Play with my clit, Donny," she sighed, "please."

Donny moved down to kneel between her eagerly spread legs and get a better look at her glistening red gash. He parted the furry lips of her muff and exposed her clit, a tiny red bud of flesh that seemed to throb before his eyes. He pressed a fingertip to the hot little lump and started to rub it, and Cindy moaned hoarsely with pleasure and creamed all over his finger.

"Ahhhh, yeah, that's it, big brother," she sighed. "Rub my clit just like that. Ohhhh, it feels so good." She let her legs fall open all the way and just lay there moaning and shivering with pleasure as her brother frigged her horny little clit. She'd never thought to touch herself or play with herself there before, and she hadn't realized how terrific it would feel. Her excitement mounted rapidly as Donny's stiff finger jerked back and forth over her hungry wet joy button.

"Ummmm, so fuckin' good," Cindy sighed.

"You're not supposed to swear," Donny said out of habit. "Mom and Dad wouldn't-"

"To hell with Mom and Dad," Cindy moaned. "They dumped us here, and we can do whatever we want."

Donny realized she was right. This summer vacation could be a blessing in disguise, leaving them alone with each other to find out all about sex. And of course they'd have Judy and Jimmy, who seemed ready for any naughty adventure. Donny grinned as he briskly frigged his sister's throbbing wet clit. No, indeed, it wouldn't be so bad being marooned on this island after all.

He watched Cindy's gleaming red slit as he rubbed her joy button. The wet flesh was puffing up, getting all swollen and taut, and her tiny cunt mouth was leaking a steady stream of thick shiny juice. Beneath his frigging finger her clit was getting its own tiny erection, growing plump and stiff and hotly throbbing. Cindy whined with pleasure and jerked her slim hips to the rhythm of his finger, obviously going out of her mind with excitement.

"Ahhhh, Donny, you're getting me so damned hot," she moaned. "Rub my clit, yes. Keep doing it. I wanta come so bad."

"Don't worry, Sis," Donny said hoarsely, "I'll make you come."

Cindy remembered the afternoon and her very first orgasm. She hadn't dreamed it was possible to get such a blast of pleasure from her very own body, and she was eager to feel it again. She whined and ground her swollen clit against her brother's jerking finger, and she felt the pleasure building in her pussy till she could hardly stand it. Her hips jerked helplessly in a fucking motion, faster and faster, and then suddenly the pleasure exploded deep in her virgin cunt.

"Ohhhhh, Donny, I'm coming," she shrieked.

Donny saw her slim curvy body start to rock and writhe. He felt his finger scalded with her helplessly gushing pussy cream. Her excitement infected him, and he rubbed hard and fast on her squirting clit, intensifying her climax. Her pretty little tits wobbled like jello, and her face was twisted in a grimace of ecstasy as she groaned and came.

Donny was so excited by the sight of his sister climaxing that his cock went stiff as a board, sharply tenting his pajamas. At last Cindy sighed and went still, looking up at him with glazed and grateful eyes. Donny grinned and slid his finger lower in her scorching juice-soaked slit. He found the tiny hollow of her cunt mouth and swirled his fingertip around and around in the juicy tight opening.

"Eeeeeee," Cindy squealed, "oh, yeah, play with me. Put your finger in me."

Donny teased her for a few moments, just rimming the mouth of her tugging cunt, while Cindy writhed and whined in mounting lust. She'd just come like a bomb, but already she was horny again, thanks to her brother's naughty finger play. She felt her little twat mouth gripping his fingertip and pulling at it as if to draw it in deeper. She needed something long and stiff in her cunt. She didn't know why, but that felt so good.

"Please, Donny," she gasped, "put your finger in farther. I want it all the way up my cunt."

Grinning, Donny slowly eased his stiff middle finger into his kid sister's exquisitely tight virgin twat. As he stuffed it into her, she whined with excitement and creamed heavily, soaking his advancing finger. He pushed it in clear to the last knuckle, and she jerked her thirsty little pussy up and down the stiff impalement, helplessly fucking his finger.

Donny shivered with lust as he felt his sister's tight teenage cunt all around his deeply lodged finger. Her box was so deliciously snug, hot and juicy. He couldn't help thinking how great it would feel to shove his cock in there. His eager young prick, already rock hard, swelled up even fatter, and it drooled a big glob of hot juice. In his excitement, Donny began jerking his finger in Cindy's cunt, making cock-like motions.

"Uhhhhh," Cindy moaned, "shit, yes, frig meeee."

Totally inexperienced, Cindy couldn't explain why this finger play felt the best of all. It had been terrific fun when Donny rubbed her clit, but this was even better. Each time his stiff middle finger lunged deep into her juicy little fuck hole, she groaned with pleasure. She loved the feeling of having her cunt stuffed and reamed. Instinctively she jerked her hips in time to his strokes, thrusting her pussy up to take his finger as deep as she could.

"Ooooo, Donny it's so good," she whined. "Frig my cunt, don't stop, I love it."

Donny was just about out of his mind with horniness as he felt her scorching wet pussy hole tugging and sucking at his jerking finger. Christ, it would be terrific to have his swollen eager cock in that juicy clinging tube! But maybe that would be going too far, he thought reluctantly. After all, she was his kid sister, and he was supposed to watch out for her welfare, not bust her cherry.

Still he couldn't get the thought out of his mind as he finger fucked her into a gasping frenzy of pleasure. He was still a teenager, after all, and that was pretty late for being a virgin. His cock felt ready to burst, it was so swollen. Sighing with horny frustration, he pumped his juice soaked finger deep into Cindy's flaming-hot box. She stiffened, gasped, and then went into powerful convulsions.

"Ahhhh, I'm coming again," she screeched. "Oooooo, it's so fuckin' good!"

Her spasming cunt closed like a vise around his finger, tugging and squeezing, and Donny almost shot his load as he imagined how that gripping hot tube would feel around his dick. Well, even if he couldn't fuck her, she could get him off. It had been wild fun when Judy gave him that hand job. No reason why his sexy kid sister couldn't jack him off, too.

Her climax had hardly ended when Donny said urgently, "Sis, jack me off, quick. I'm so horny I can't stand it."

"Sure, Donny," Cindy said eagerly.

She'd been aching for a chance to see and touch her brother's prick. Now Donny flopped onto his back, and she quickly tugged off his pajama bottoms. Then she just had to pause and gawk. His cock looked huge. Standing straight up from his belly, the thick six inch rod weaved heavily, blue veins standing out on the pale flesh. The head of his cock was a big red knob that leaked bright bubbles of juice. Cindy shivered with excitement.

"Hurry, Sis," Donny whined. "Don't just look at it-play with it."

Cindy giggled and reached for his cock. Now the tables were turned. She was in charge and could drive her big brother into a horny frenzy, just like he'd done with her. She wrapped her fingers firmly around the hot throbbing pole of his cock and began to pump. The silky skinned meat lurched in her fist and dribbled hot juice over her fingers. Donny gasped and moaned as she briskly jacked his cock.

"Jesus, yeah," he cried, "just right. Fuck, that's good."

"You're not supposed to swear," Cindy teased. "Mom and Dad wouldn't like it."

"Fuck that," Donny laughed.

His sister's fist was hot and tight around his achingly swollen cock, and she was pumping fast, squeezing and releasing the bloated hot meat.

Somehow it was a lot more exciting to have a girl jacking him off than to do it himself. Donny sighed blissfully and eagerly waited for a much-needed orgasm. But just as he was about to come, Cindy let go of his cock.

"Shit," Donny moaned. "Why'd you quit, Sis? Dammit, I was just about to get off."

Cindy's brown eyes were hot and horny. "Listen, Donny," she panted, "I was just thinking. Instead of doing it this way, why don't we fuck? I'm just dying to know what it's like."

Donny groaned. This was going to be a helluva decision. He knew he shouldn't fuck his own sister, especially when she was a teenage virgin. But on the other hand, he was dying to get rid of his own cherry, and Cindy seemed so eager and willing. Nobody would ever know. Why not grab the chance? Donny felt his resistance melting rapidly.

"Come on, Donny, please!" Cindy cried.

She rolled onto her back and opened her legs wide, showing him her achingly swollen pussy. In spite of two delicious orgasms, she was still hotly horny. She only knew that she needed something big and hard in her cunt, that she hadn't gotten enough of that sensation yet. Donny's frigging finger had felt so good, but wouldn't his thick hard cock feel even better?

Donny swallowed hard as he stared at his sister's gleaming wet slit. He saw her tiny recessed cunt mouth opening and closing greedily, as if aching for the deep thrust of his cock. His balls felt ready to explode with their hot load. He just couldn't pass up this chance to fuck a girl for the very first time, even if she was his sister. He moaned and crawled between her legs.

"Oh, yeah, Donny, do it to me," Cindy panted. "Stick your cock in me."

Shivering with excitement, Donny touched the hard swollen head of his dick to his sister's gasping little cunt mouth. The flesh was wet and scorching hot, and the first touch was electric. He damned near came. Moaning, he popped his fat red cock head into the mushy hollow of her twat mouth, and he felt his prick gripped and squeezed by her powerful young cunt.

"More," she panted, "put it into me more."

Donny caught his breath and began to glide his bloated prick slowly into her frantically tugging fuck hole. He wanted to savor the moment of losing his cherry. Very gradually he felt his cock enveloped in steaming-hot slick flesh. Her cunt was very tight, squeezing and gripping his dick. Underneath him Cindy was shivering violently.

"Oh, my gosh," she gasped, "your cock's so big."

As Donny slowly eased his bloated steel-hard prick into her virgin cunt, she felt stuffed breathless. She was glad he was going slow, otherwise it would surely have hurt. As it was, the fit was so tight and her tiny cunt so hugely stretched that she was afraid she'd be split in half. Still she wasn't going to chicken out, not now. She just had to know what fucking was like.

"Ahhhhhh, Christ," Donny whined, "so fuckin' good. Your cunt's so tight, Sis, so damned hot."

Cindy didn't say anything. She was still wondering whether she was scared or excited. Donny's slowly impaling prick was sliding over her greedy little clit, and that felt very nice, but she still feared his thick cock would tear her tiny cunt. He grunted and pushed again, and his swollen hairless balls came to rest against her slit. The thick hard base of his cock stretched her dainty pussylips almost to bursting.

"Awwwww, Jesus, I'm all the way in," Donny groaned. "It's so friggin' good. How does it feel to you, Sis?"

"I-I don't know," Cindy said in a scared little voice. "Your cock's so big, Donny, I'm afraid it'll hurt me."

"Naw," Donny said soothingly, "I wouldn't hurt you. I'll go slow and easy, okay? If it starts to hurt, I'll stop."

He sure as hell hoped it wouldn't hurt, because he didn't want to stop, ever. He began to move his cock in her, fucking a scalding slick pussy for the first time, and he felt a powerful urge to ram it to her, to slam his achingly bloated meat into her as hard and fast as he could. But he managed to control himself, not wanting to hurt her. Cindy quivered beneath him, her hard little nipples jabbing his chest.

"How's that?" Donny panted. "Feel okay?"

"I guess so," Cindy whimpered.

She still wasn't sure, for with each slow deep shove of his cock, her tiny cunt was stuffed so tight she could hardly breathe. But she wasn't giving up now. They were actually fucking now, and that idea excited her. Gradually, as his stiff cock raked back and forth over her horny little clit, it began to feel good. His thick shaft tugged at her cunt lips, sending shivers of pleasure through her pussy. She relaxed and began to cream around his cock.

"Ummmmm, Donny, it feels nice now," she sighed. "Yeah, you can fuck me faster if you want."

"Far out," Donny moaned.

He instantly speeded up his fucking, cramming his bloated throbbing prick fast and deep in her boiling little box. That was the way he really wanted to fuck her, pulling out all stops. Cindy gasped and squealed with the first rough thrusts, but then he felt her hot cream oozing around his cock again. The flow of syrupy juice got heavier and heavier as he fucked into her, and then she was moving her hips in time to his strokes and digging her nails into his shoulders.

"Ahhhhhhh, Donny, now it's really feeling good," she moaned. "Yeah, big brother, fuck it to me."

"You bet I will," Donny grinned.

He started slamming his eager young prick into her as hard and fast as he wanted, their bellies smacking loudly together with each deep thrust. Cindy gurgled with pleasure and humped right along with him, her aroused cunt expanding to take his thick meat. She creamed helplessly, and his plunging cock reamed the juice out of her tiny box. She felt the scalding stuff dribbling down her ass crack and puddling on the sheet beneath her. His fucking was feeling better and better to her.

"How is it now, Sis?" he panted. "Am I fucking you too hard?"

"Nooooo," Cindy whined. "Oh, Donny, I love it, I love to fuck. Your big cock feels so damned good in me. Don't stop. Fuck me crazy."

Donny slipped his hands under her churning little ass and pulled her tight against him so he could fuck into her as deep as he wanted. His knobby cock head began to batter her womb, but she didn't protest. She clung to him, clawing his shoulders, and she frantically humped her gushing pussy up and down the rigid thick pole of his cock. Her gripping cunt seemed to get hotter by the second.

"Ohhhhh, Donny, you're driving me wild," Cindy moaned. "I love your fucking, big brother, I love it!"

"I love fucking you, too, Sis," Donny panted. "Awwww, shit, it's good."

It was better than either of them had dreamed. All that finger play, alone or with their cousins, had been fun, but it was nothing compared to this. They knew they'd never go back to those kiddy games, not after they'd discovered fucking. Brother and sister groaned with pleasure and jerked their bodies in identical rhythm as they eagerly fucked at each other. The bed began to creak and groan.

"AHHHHH, FUCK, SHIT, AHHHHHH!" Cindy wailed. "I'm gonna come, Donny, yeah, yeah, NOW!"

As her convulsing cunt closed hard around his cock, Donny yelped, "I'm coming, too, Sis. Take Cindy felt the scalding spray of her brother's jizz deep in her gripping pussy, and it seemed to make her orgasm even more intense. The two kids whined and howled and jerked together till Donny's cock went limp and exhausted. He rolled off her with a deep sigh.

"Fantastic," he panted.

Cindy grinned wickedly. "You won't try to turn me down next time?" she said.

"No way," Donny laughed. "I'm hooked. How about you?"

"Definitely hooked," Cindy giggled. "From now on I'm a fuck junkie."
