That night

Young Billy Richards lay in bed stroking his erect, healthy young cock, his mind alive with visions of his mother masturbating outside the Jordans' cabin window.

Like most boys, Billy jerked off a lot. In fact, Billy would often beat his meat once or twice a day. And again, like most boys, he used all sorts of ways to get his cock hard, and to reach that lovely, bursting moment of self-induced orgasm.

Sometimes he used pictures--he especially liked the ones that showed two or more chicks sucking each other off--and sometimes he used books, and sometimes he just let his mind play, whipping his root while he fantasized about fucking the shit out of some fox he knew at school, or had seen on the street, or in a movie. Sometimes he even got himself off thinking about his sister, Debby, although there hadn't been much need to do that lately.

At least, there hadn't been much need to fantasize.

Because about six months earlier, the relationship between Billy and Debby had taken a new turn. It had all started one cold wintry evening when Billy had walked into her bedroom without knocking ...

Sixteen-year-old Debby Richards was just in the first stages of blooming womanhood. She had a little ways to go before her titties would reach the full firmness of her mother's, but her teenager's ass was already well-rounded and fine and it was more than obvious that, before long, she was going to be one gorgeous piece of woman.

She wasn't gorgeous yet; cute was more the word that seemed to best describe her, with her mother's facial features and her long, brown hair. But it was a sexy cute. The kind of cute that made middle-aged men turn and watch as she walked briskly by on her way to school; looks aimed at that twitching ass under a short skirt, or the perky bounce of those lovely, still-blossoming boobs. Many a man's mouth had watered--and no doubt many a man's and many a boy's dick had gotten hard--at the sight of little Debby Richards, because little Debby was a fox. A stone fox.

A stone fox who, though she had lost her cherry in the back of a station wagon at a drive-in movie one night, and though she still, on very rare occasions, went "all the way" with high school dates that she particularly liked, retained a virginal innocence that had, for a long while, kept most people, including her mom and brother, totally fooled.

But all of that, at least as far as Billy was concerned, changed on that fateful night when, forgetting to knock, he stepped into her bedroom to ask to borrow a pencil for some homework he was doing.

Nikki had been out with some friends that night and the house was quiet, but it was still early and Billy had no reason to suspect that his sister would be asleep yet. Without a father, and with their mom gone working most of the time, the two children had grown quite close, closer than most kids, in fact, and they were almost as much friends as brother and sister. And so it was without a second thought that, with a cheerful smile on his lips, Billy opened the door to Debby's bedroom and began speaking before he was even all the way in.

"Hey, Sis," he started. "The lead in my pencil just broke and I was wondering if--"

And that was as far as he got. The smile disappeared from his face and the sight that met his eyes temporarily froze him in his tracks.

And what a sight it was!

Little Debby--virginal, Sixteen-year-old Debby--lay stretched out across her bed, masturbating ... and loving every second of it! The scent of her aroused, horny young cunt filled the room.

She was wearing a baby doll nightie of filmy, lacy cotton that stopped just above the panties. Only she wasn't wearing the panties now. They were in a tangled ball on the floor alongside the bed. With one hand she was reaching under the top of the nightie, playing with her nipples, and with her other hand she was wiggling her middle finger in and out of her dripping twat. Even from where Billy stood he could see that the fingers of her jerk-off hand were wet and slick with cum.

An open paperback book, a porno novel, lay on the bed beside her, but she wasn't paying attention to that now. She had passed that stage; she'd obviously been going at it for quite a while. Her eyes were clamped shut, her breath was coming in gasping, little-girl moans, and her hips were rotating and rising and falling in time to the finger diddling away at her clit.

"Ohhhhh..." she was moaning. "Mmmmmmmmm ... that's sooooo nice ... mmmmmmmm..."

Billy couldn't believe his eyes.

"D-Debby--" he blurted, his hand still holding onto the doorknob.
Her eyes jarred open. Her hand stopped diddling.

"Billy!" she gasped. "Ohhhh--"

They remained there like that for another moment, both of them trying to get a grasp on the situation, both of their minds reeling.

"Wh-what are you doing?" Billy asked dumbly.

She couldn't answer right away. "I-I--" she began, and then she gave a whimper. "Oh, my god--"

Billy closed the door and leaned back against it, and a little smile played at his lips. He was over the shock of discovering Debby, and his mind was quick to grasp what a painful experience this could be for her if he didn't handle it just right.

He stepped forward, still smiling. "It's okay, Sis," he said softly. "I-I understand what you were doing."

"Oh, Billy--"

He sat down on the bed next to her and touched her in a brotherly fashion on the shoulder.

"Heck," he added with a chuckle. "I do the same thing myself, all the time."

Debby had taken her hands from her pussy and boobs and had propped herself up on an arm to look at him. She was recovering from the shock of being discovered.

"R-really?" she asked falteringly.

"Sure," Billy said. "Gee, Sis, it's ... it's something everybody does, only ... only they just don't talk about it, know what I mean?"

"And ... and you do it too?"

"I said everybody, didn't I?" He reached over and looked at the book. "And what's this my little Sis is reading? SWAPPING WITH MOTHER, eh?"

His grin grew wider as he read the title. "You wouldn't have the hots for our mother, would you?"

"Oh, Billy, no," she blushed. "Don't tease me. It was ... it was just given to me by one of the girls in my gym class at school. I ... I just started reading it and ... I just ... I just had to do something..."

Billy paged through the book. It did indeed seem to be an especially "hot" piece of porno writing. On nearly every page, it seemed, there were descriptions of hot thrusting cocks and wet horny pussy and swirling tongues and sweating, moaning bodies.

All of a sudden, Billy realized that Debby was giggling.

"Huh, what's that?" he said, looking up from the pages of the book.

"There," Debby said. "You see, you've got no right to tease me about that book. Look what happened to you when you started reading it!"

Billy looked in the direction of Debby's gaze, and he felt like blushing himself. Underneath the crotch of his tight jeans was the clear impression of a hard-on. But not a full-fledged hard-on just yet. It was just coming to life as he looked. It had been caused by one of the scenes he had glanced at in the book, and it was throbbing, growing, even as they watched it.

"I-I guess that proves my point," Billy said after some initial embarrassment. "See, the book turns me on too. Nothing wrong with that."

"I-I guess not," replied Debby.

"Heck, Sis, that's what happens to me all the time when I read these things. There's nothing wrong with it at all. Uhh, you, uh, wouldn't mind if I borrowed this book for a while, would you? To take back to my room..."

Their eyes connected and now it was Debby's turn to shoot him a slight grin.

"And what is my big brother going to do with the book when he gets alone?" she asked.

"Why ... just what you were doing, of course," he said with a laugh.

The atmosphere of the room was completely relaxed now. Debby felt that she was one lucky girl to have a brother as together as Billy. He always seemed to know how to handle situations.

"All right, Billy," she said softly. "I'll give you the book ... in the morning." She smiled. "After I've had my jollies with it."

"Fair enough, Sis," he said, standing, feeling that the conversation was over. "And ... I'm sorry I barged in on you like that. I'll be a little more thoughtful in the future, I promise you."

"Thanks, Billy. I love you."

"I love you, Sis. Good night."

He turned and started for the door when a new thought hit him. It came to him completely by surprise, and he paused with his hand once again on the doorknob, not quite sure whether or not it would be cool to bring it up.

Debby sensed his hesitation.

"Billy ... is something wrong?"

He turned slowly. "No, Deb. It's just that ... well, I had this idea, but ... no, no it's too kinky. I'm sorry, I shouldn't have said anything. I'll just--"

"Well you've got my interest up now, silly," she said. "What is it? Let's hear it."

"Well, uh ... I was just thinking. Y'know, we're both pretty, uh, pretty excited right now..."

"Boy, I'll say..."

"And, uh, we're probably both going to be ... uh, doing the same thing, right?"

"Yes..."

He closed the door and came back into the room to sit beside her on the bed once again.

"Well, I was just thinking," he said slowly. "Do you ... do you think it would be too weird if we ... if we did it together ... if we made ourselves cum while we ... while we watched each other do it?"

Debby couldn't say why, but the instant she heard the suggestion, the nipples on her little titties grew hard all over again and she felt the walls of her small, tight pussy grow damp with new juices.

"Oh, Billy..."

"Let's do it," he pressed. "Sis, I feel like we're really close now, after tonight. And, after all, sex is to be enjoyed, isn't it? And it's not like we're doing something really kinky. Heck, we don't even have to touch each other. I just ... I just think it would be really a turn-on to watch each other get ourselves off."

"It ... it does sound exciting," Debby admitted in a small voice.

Billy saw that he was close to talking her into it, and he continued in his most convincing voice. And it was easy for him to sound convincing. Shit, right then he would have given anything to see his baby sister once more sprawled out across her bed, fingering her lovely pussy.

"Seeing you like that before really turned me on," he said truthfully. "It turned me on even more than the book you were reading. And maybe ... maybe watching me will turn you on just as much. Gee, Deb, it really sounds nice to me. I-I don't see what harm can come of it."

"And I don't either," Debby said, making up her mind. Her eyes drifted back to the impression of his now totally hard cock. "Ohh, Billy, it looks so big ... so strong. You're right, I do get excited just thinking about watching you play with it. Can I ... can I see it now?"

"If I can see what you've got?"

She nodded, but even as she spoke she was unable to take her eyes from the bulge.

"It's a deal," she said. "Mmm, Billy, I'm so excited. Let's do it right now. We've ... we've got to be careful so we're not caught by mom..."

"We'll be careful," Billy said. "Yeah, let's do it now. You're not the only one who's steamed up, Debby. Jeez, did you look foxy when I walked in and saw you. I can't wait to watch you again!"

Together, they slipped out of their clothes: Debby once again out of her short, filmy nightie and Billy from his shirt and shoes and socks and his tight jeans.

Debby gasped when he finally slid the jeans down his legs and stretched out sideways across the bed beside her, so that both of their legs were hanging over the edge and only the flesh of their arms was touching. Billy's hard young prick stood at full attention, pointing directly at the ceiling, and Debby stared at it with wide eyes.

"Goodness," she said in a voice that was half a moan. "It's so big ... and strong-looking. Billy, it's ... it's lovely ... and you're so ... so excited!"

"What about you?" he grinned. "Look at those beautiful titties of yours..."

Young and smallish as they were, Debby's tits were indeed works of art, and as they were flattened now because she was lying down, the nipples were especially noticeable. They were coral-colored, erect and terribly excited.

Billy couldn't help himself. He reached over and ran his hand up his sister's warm outside thigh. Her smooth white flesh seemed to quiver with excitement under his touch. The tips of his fingers moved over her hips, up along her warm, flat stomach, up over her ribcage, and at last came to a stop, after the maddeningly slow journey, just beneath one of the Sixteen-year- olds jugs. He traced the tips of one of his fingers across a nipple.

"So nice," he sighed. "Debby, you're soooo nice!"

Debby closed her eyes and moaned. "Ohhhhhhhhhhh, Billy ... that feels so good ..."

Billy just couldn't stop then. He rolled onto his side and brought his lips near her ear. His cock and balls ached, he was so horny. He rested his free hand on her warm, quivering young thigh, and his hand at her boob began feeling her more strongly. He worked his palm in a circular motion over the excited nipple.

"Ohh, Debby," he groaned. "I need you, Sis. We need each other ..."

Debby started to moan again, but then came to her senses. With a startled gesture, she brought her hand up and slipped her fingers gently yet firmly around her brother's wrist.

"Billy ... wait ... no," she said falteringly. "We can't ... we can't do that ..."

With a sigh, Billy moved his hand from her thigh and pulled his face back from her sweet-smelling hair.

"You're right," he said. "I'm sorry. I'm ... I'm just so goddamn horny!"

Her breathing was coming so fast that Billy could hardly discern her words. Her hips seemed to be rotating with a life of their own and a thin coating of tangy-smelling sweat covered her body. She had spread her legs as far apart as they would go and one of her hands dropped down to the bush surrounding her cunt.

"Billy ... Billy," she moaned. "I'm so excited too ... I'M ... I've got to make myself cum right now. When you played with my titties, ohh, it felt so good ... ohhhhh ... mmmmmm ..."

She had already begun screwing her cunt with her middle fingers. Billy felt a dribble of juice seep from the piss-slit of his prick and drool down the length of his shaft to sparkle in his pubic hair.

"Cum on Debbie....cum for me"
"Ohhh, Billy--"

Debby was a "good girl." She'd never heard "dirty talk" before from a boy or a man. But now, seeing her brother's immense hard-on, feeling her own pussy juices gushing from her teenage twat as she diddled herself frantically, and remembering the lovely touch of her brother's fingers on her nipples ... the words he spoke, and the horny way he spoke them, were almost more than her senses could stand. Her whole body began to shudder with delightful sexual quivering, and she was ready to do anything for him to help him feel the thrills she was experiencing.

"Oh, yes ... yes, Billy ..." she panted.

She was still holding him by the wrist. She brought his hand down toward her hot mouth now and her tongue licked out, covering his palm with her spit. Her spit was thick and hot from her excitement.

"Thanks, baby," he groaned. "Oh, thank you ..."

Then he took his hand and began sliding it up and down his horny prick. In an instant the shaft was slick and shiny with his sister's saliva. He felt his ass cheeks tighten as he played with himself faster and faster, all the while his eyes drinking in the beauty of his kid sister, lying there beside him, holding and playing with one of her titties while she lay there moaning and writhing and twisting against him, fingering her cunt while her eyes were locked to what he was doing!

The bedsprings creaked beneath them as both of their hands moved faster and faster. Debby had her feet up on the edge of the bed now, her hips bumping and jerking like some topless-bottomless go-go dancer. She was moaning, her climax coming on faster, faster, and faster.

"Ohhhhh!" cried Debby at last. "Ohhhh, I'm there ... I'm cumming ... oh oh oh oh oh ..."

Her fingers stopped for just a second. Her whole body seemed to lift off the bed and just hold like that as the unbelievable strength of her orgasm hit her with all the **** it had.

"AAAAAAHHHHMMMMMM!" she squealed. "OHHHHH ... I'M CUUUMMMMIIIIIINNNNNGGGG ... OHHHHHHH ... AAAAAAGGGHHHHHMMMMM!!"

It was like a bomb going off. Billy had never seen anything like it. She writhed and bucked and twisted on the bed like a soul possessed, all the while fingering her cunt and tit, squeezing and pinching them in her pleasure.

It was all Billy needed to send him over the edge as well.
"OHHHHHH ... OHHHHH ... ME TOOOOOO ..." he groaned. "OH DEBBY ... OH, SIS ... I'M SHOOTING MY CUM!"

As he gripped his cock with his wet, slippery hand, Billy's load exploded from his dick as if fired from a cannon. It was thicker and hotter than usual, and there was more of it than usual too. As he continued to stroke himself, creamy jets of sperm arced out into the air, landing on the bedspread, on his legs, and on Debby's smooth, tanned legs as well.

The moment of supreme lust seemed to last forever as both children continued to diddle themselves long after the actual moment of orgasm had passed, in an attempt to milk every drop of pleasure from the experience that they could ...

Yes, that had been the first time, and that was why Billy had lately not been fantasizing about Debby as often as he used to when he masturbated.

There had been many other times as well, as if the brother and sister had discovered a new toy which, in a manner of speaking, they had. And as the months passed, the sexual intimacy between the two children had increased. While they had never actually balled, they had managed to invent a number of variations on their side-by-side diddling adventures.

Sometimes one of the kids would read to the other from a porn book, read a particularly hot scene, while the other masturbated to a climax.

But the most enjoyable game of all was when brother helped sister get off, or vice versa. At times like these, one of the children would lie on the bed and the other would masturbate the other to climax, but that wasn't all. While Debby was pumping on Billy's hard young shaft, she would paint fantasies for him in the most vivid descriptions she knew, or sometimes she would relate to him her own sexual fantasies. And of course, Billy would do the same for her, whispering hotly into her ear the things she liked to hear while he pumped his fingers furiously in and out of that hot little cunt that never seemed to be able to get enough.

Yes, this was the sex life the two Richards children had been sharing for the past six months or so, and they both found it to be quite a satisfying one. There seemed to be no reason for either child to imagine that anything would change, simply because they had moved from Milwaukee for the summer.

No reason at all ...

"Billy, are you at it again?"

At the sound of his sister's voice from across the bedroom, Billy temporarily discontinued the mental vision he'd been holding of his mother getting her rocks off. He stopped stroking his pecker and looked across the room.

Not that he could see anything. It was pitch black. The nights up here in Door County weren't like they were down in the city. Up here there were no street lamps or headlights driving by every few minutes. There was nothing but total stillness, and it was so dark that you couldn't see a hand before your face.

Billy and Debby had been asked by their mom before coming up here if it would be all right with them if they shared a bedroom. The cabin that served as the office and their living quarters was small, much smaller than they were used to, and had only a tiny front room which also contained the desk for guests to register, and two small bedrooms, one on each side of the front room.

Naturally, the kids had not minded at all. In fact, they were more than happy to adapt. It made their sex games that much easier to play!

Debby was in her own bed across the room, and Billy had thought she was asleep when he'd started toying with his cock. Shit, sometimes it was still fun to do it the old way. Getting yourself jacked off by someone else was a trip, but when you did it yourself, you could time it just so. And besides, this time he wasn't sure if he should confide in his sister what he was thinking, the way he usually did. He wasn't sure it would be night to tell Debby what he had seen Mom doing to herself that afternoon behind the cabin.

But he hadn't counted on his sister's keen ears, and when the slick sound of his damp palm sliding up and down his erect shaft had reached her ears, she must have known immediately what was going on.

"J-just having a little fun, Sis." he answered softly, with a chuckle.

"Is Mom asleep?"

"I think so. All the lights seem to be off."

"Do you want any company over there?"

The way Debby asked the question, Billy could tell that she expected a yes answer but, with his hand still around his dick, he took a moment to reply.

"I-I don't know, Sis," he said finally.

"Uh, okay ... nothing's wrong. I ... just feel like getting my own self off tonight, y'know?"

"Sure, Billy," she said. "Sure."

There was silence for a moment after that, and then the rustle of material from Debby's side of the room, and Billy knew what was happening. In another instant the smell of aroused cunt drifted across to him, and he knew that Debby was beating herself off too.

Aww shit, he finally thought to himself. What the hell! He knew his kid sister well enough to know that she had a kinky streak a mile wide. There was no doubt that Debby would really get turned on if he told her what he had seen that day. What would be the harm, really?

No, he decided, he was just being selfish in keeping a turn- on like this to himself.

"Heck, Sis," he said at last, keeping his voice at a low whisper. "Light a candle and come on over here. I got some things to tell you that'll give you the cum of a lifetime!"
