Chapter 6

Robyn's parents were returning the next day so we had to say good-bye. She made a point to come up to the apartment early that morning for a quick fuck. She came up alone, telling Michelle she didn't want to share me.

As soon as I'd closed the door she dropped her jeans and panties on the floor and we had a quick, hard fuck on the carpet. Over the next hour we tried a few new positions, taking our time and having some nice orgasms. It was better than morning coffee.

Afterward, we held each other for a little while and vowed to get together again before I left town. I hoped we could.

Michelle stopped by again in the afternoon wearing what was fast becoming her favorite outfit: short skirt, summer top, no bra, no panties. I must admit it was my favorite outfit for her to wear, too. We talked about the fun we'd had with Robyn and how we were going to miss her during our afternoon sex sessions. Michelle said she had a couple more friends that she thought might be interested in our little group; she'd talk to them.

Then she began to tell me about their little adventure after they had left my apartment the previous afternoon. Tom had gone off to meet some friends but had returned later in the evening. Michelle's mom was gone again for the night, so the girls took a shower together and put on long T-shirts but nothing else. They enjoyed the relaxed, sexy feeling of freedom they felt when wearing very little clothing.

Michelle said that they decided to sit up and watch a movie they had found under the bed in Tom's room, a porno movie. Michelle knew that her brother had several of them, and had enjoyed watching them when she was home alone.

When Tom came home, he found the two thirteen-year-old girls sitting on the floor watching the movie. He was angry at first, but thought, 'What the hell', and decided to join them. Besides, he could see the bottom curve of their cute bare bottoms and the jiggling of their round breasts underneath the T-shirts and he licked his lips, anticipating the fun that he knew was to come. Joining in the game, he went into his bedroom and put on a pair of gym shorts, the kind he usually wore when he went to bed. But, he decided not to wear his underwear, and his cock and balls hung unencumbered down the loose leg of his gym shorts, almost exposed. Dressed this way, he went in and sat down next to the two young girls on the floor.

The movie was constant sex and the kids began to get excited. Right away Tom's cock started getting hard, and the junior high school girls could see it get long and large and the tip begin to appear through the leg of his shorts. Tom didn't seem to mind. In fact, the thought of his cock being exposed to the sight of his little sister and her friend made him even more aroused.

The girls gazed down at the boy's lap at the dark reddened tip as it slowly appeared through the leg of his gym shorts. They giggled at the sight, but it made them horny, too.

Michelle was laying on her stomach beside her brother, head on her hands, watching the television screen. Her T-shirt had crept up her ass so that the bottom of her shapely, naked behind was exposed and her legs were spread apart slightly. Glancing down, Tom enjoyed a glimpse of the silky, light brown pussy fur that peaked out between her thighs. As the three kids watched the sexy movie, Tom thought dirty thoughts about little his sister and how eagerly she had performed oral sex on him earlier that afternoon. Maybe she was willing to do even more.

Boldly, he put his hand lightly on the back of his little sister's leg and caressed the warm, soft skin just behind her knee. When she didn't say anything, he moved his hand higher up her leg until, at last, he slid it up into her slit from behind. The boy gently rubbed the top edge of his hand back and forth between the lips of her pussy and felt the wetness begin to flow. Playing with her cunt felt so good and made his cock so hard; he couldn't believe his little sister was letting him do this to her, and waited for her to stop him. He was surprised at her reaction.

"Mmmm... yeah, play with my pussy," said Michelle, looking back at him with a horny grin and wiggling her ass, "that feels good."

The always horny little thirteen-year-old girl moved her legs apart a little more to make things easier for him and went back to watching the movie. Everything seemed more exciting now that her older brother was sitting next to her on the floor fingering her hot little cunt.

Tom just couldn't resist the way this whole thing was heading and, after a minute of manipulating the outer folds of her cunt with his finger tips, he slipped his middle finger deep down into her wet hole. Slowly, the fifteen-year-old boy began to move it in and out, tenderly finger-fucking his little sister from behind as she lay on her stomach beside him. He looked down with undisguised lust at her small, shapely ass as, with each penetration, he buried his finger up to his hand completely inside her.

He could feel the soft, rubbery tightness of her little cunt opening grip his probing finger as he slipped the shaft in and out. His breathing was faster, his own sexual arousal increasing as he looked down and watched what he was doing, adoring the sight and feel of his fingers exciting his sister's wet pussy. He was becoming so aroused by this forbidden sex play that his cock felt like hot iron as about half of his shaft poked out through the loosed leg of his gym shorts.

Exploring even more, he pulled his moistened finger out of her pussy and began to run the slippery shaft up over her asshole, stimulating her other intimate pleasure point before poking his finger back into her cunt. He wanted to find out how far his sister would let him go, so he thought he'd try something that one of his eighth grade girlfriends had liked him to do to her. After several passes over her asshole he timidly, but firmly, pushed the tip of his middle finger past the puckered opening and into her butt. It penetrated up to the first knuckle.

"Mmmm... yeah, push it into my ass - I like that," Michelle sighed, wriggling her behind at the increased sensations of pleasure.

He felt his thirteen-year-old sister push back against his finger, trying to get more up her asshole and inside her. He stroked his finger back and forth several times, the tight entrance to her butt gripping the small shaft as it slipped about half way in and out. God, this is incredible, he thought I can't believe my little sister is letting me do this to her - and she likes it!

It was really exciting knowing he was finger-fucking his little sister in the ass, but his hard, throbbing cock ached to find a more accessible hole. He figured he'd try her butt hole again another time; maybe with something other than his finger.

Pulling his finger out of her ass, he inserted two fingers into her pussy, stretching the entrance and moving them slowly in and out, just enjoying the feel of the soft, warm, wetness of her cunt opening. Her oily juices completely coated his fingers and hand now, the smell of her sex was heavy in the air.

The kids continued to watch the sex movie, Tom casually fingering his little sister's cunt, his stiff cock pulsing and pushing out through the loose leg of his shorts. Robyn had watched with rapt interest the brother and sister so obviously enjoying their sex play and decided it was her turn to have some fun, too. She laid her hand in Tom's lap, grasped the exposed cock head between her little fingers, and slid her hand up and down the length of his smooth prick, even into his shorts.

She was sitting cross legged next to the boy and, as she jacked Tom off, the horny little girl slipped her other hand up underneath her short T-shirt. Now, she could really enjoy herself as she plunged her middle finger in and out of her exposed cunt. Her slit felt so warm and wet from watching the sexual happenings, both live and on the screen.

The kids were becoming more and more turned on by the sexy movie and the sexual stimulation they were doing to each other. Tom was constantly sliding his first two fingers into his sister's pussy hole from behind, joyfully finger-fucking her. Sometimes, for fun, he would split his fingers apart and enter her pussy and asshole at the same time, pushing both deeply up inside the horny thirteen-year-old girl.

Michelle really liked the sensation of her brother's fingers moving in and out of her cunt and butt hole. That wonderfully warm, heavy sensation began to grow deep in her loins, and she ground her furry pelvis down into the carpet, wiggling her cute behind and stimulating her clit, adding more sensations to the ones that were building so hotly between her legs.

Robyn was finding it a little difficult to jack off Tom. His cock wasn't very slippery so her hand didn't move very well over the smooth surface. But, she knew what to do to make it better and got on her knees beside the boy, bent down, and pushed the leg of his shorts up, exposing more of the boy's delightful and inviting sex shaft. She leaned over his lap and covered his cock with her wet mouth, licking over and around the sculpted red tip several times before closing her mouth over the tip and engulfing the head.

Tom stretched his legs out, quick to give the sexy junior high school girl better access to his shaft as waves of pleasure rolled over him. Robyn slid her hands into the open legs of his shorts and gently massaged his balls. Her fingers gently stroked the hairy sac between them as her mouth moved slowly up and down his length, wetting him with her warm, sucking mouth. Now, her hand could easily slid up and down his slippery prick, and the dark-complexioned girl eagerly mouthed the teenage boy while jacking him off at the same time. She wanted to make him shoot, to feel the pleasure and power of making the boy cry out in that pleasure nearly as intense as pain. God, it was so dirty... so fun...

Tom groaned out loud, the feeling of his sister's horny little friend's tongue swirling around his cock nearly overwhelmed him. Robyn was on her knees beside him, her head moving slowly up and down, as she wantonly licked and sucked at his erection. Her smooth, round, inviting little butt was naked as her T-shirt slid down her back and bunched down around her shoulders. Tom reached over the young girl's back, wanting to use his other hand to slip his fingers in and out of Robyn's pussy from behind and play with the folds of her hot little pussy.

Feeling his probing fingers move up and down through the crack of her ass, she turned slightly toward him and separated her knees, excitedly opening her thighs so he could reach her drooling sex slit more easily. He found the wet, slippery opening to her cunt and plunged the middle finger of his left hand in and out of her tight, wet fuck hole. Both of his hands were busy now, arousing and exciting the two sexy little junior high school girls at the same time.

The three kids had forgotten the sex scenes in the movie they'd been watching. They were creating their own sex scene, bringing pleasure and enjoying each other's responsive young bodies.

Tom's probing fingers continued to stimulate his little sister's cunt and ass. The delicious warmth of her brother's attention was beginning to build more and more in her loins, and she needed, wanted more of him. She turned her head and looked back at him.

"God, I'm horny. Wanna me fuck me? I'll let ya..."

The boy shouldn't have been shocked or surprised by his little sister's request, but he still was. Fingering her sweet little-girl pussy or sharing oral sex was one thing, but taking that last forbidden step was another. Sure, he'd been admiring her developing body for a quite while, often watching the young girl as she moved around the apartment in her pajamas, his cock hardening at the sight of her growing breasts and rounding hips and ass. Watching her always made him horny, but he usually found an outlet for his pent-up sexual tensions: a willing girl friend or just getting himself off in the privacy of his own bedroom.

But his secret dream was about to come true: his nubile little sister wanted him to commit the ultimate act of incest; she was asking him to fuck her. And right now he wasn't about to refuse, though his sister's friend was certainly making him feel really good by licking and sucking on his cock.

Somewhat reluctantly, Tom pulled himself away from Robyn's sweet, adoring mouth, stood up and went into his bedroom. After a minute he returned, a condom sheathing his throbbing erection.

Michelle excitedly watched her brother walk towards her, his wonderful cock thrusting out from his loins. The erect shaft swayed slightly from side to side as he moved.

"Do me like this... from behind," she told him as she lay on the floor wiggling her shapely little behind in wonderful anticipation of the pleasures to come.

He knelt over the back of his sister's hips as she lay on her stomach, and put one knee on either side of her ass. Pushing his cock down with his right hand through the crack of her ass, the young boy felt the tip slip through his little sister's slit and find the moist, slippery opening to her sex. As he felt the warm tightness of her pussy lips surround the sensitive tip of his cock he thrust forward with his hips and entered the sexy thirteen-year-old girl from behind.

Her tight, little-girl cunt was already very wet and oily from his probing fingers and his cock slipped easily and completely into her. Tom sat still for a minute, perched on the backs of her thighs, the roundness of his little sister's ass feeling warm and sexy against the crease of his thighs as he sat mounted on her. Both of the kids enjoyed the feeling of penetration, the sex especially nice because of the relationship between the two.

The grip of her cunt around his shaft felt so good that the boy just couldn't stay still. After just a minute of enjoying the delicious sensation of being inside his little sister's pussy, he leaned forward and supported himself with his hands on the floor on either side of her body. In this position, on his hands and knees, he rocked slowly back and forth, mounted on her from behind, his cock slipping in and out of his little sister's warm, wet pussy. She was really tight, like Robyn, but the fact that it was his own sister made the fucking so much more exciting.

Michelle lay underneath him on her stomach with a big, lusty grin on her face, her slender legs spread slightly allowing his slow thrusts to deeply penetrate her. His boyish cock felt so good as it rubbed over her sensitive clit each time it slipped in and out of her. She could feel his loins bump up against her ass as he pushed his prick deep inside her, the thickness filling that empty place that begged to be filled between her thighs. God, she thought, this feels so good! I hope Tom'll want to fuck me a lot.

The movie was showing an orgy sex scene with a large group of people, and the kids watched as they themselves were being physically, sexually aroused. Tom and Michelle both gazed lustily at the screen even as Tom's cock moved slowly, deeply in and out of his sister's horny pussy. Robyn was kneeling on the floor next to the couple, her fingers busy up her own wet snatch, more interested in watching the live sex show in front of her then what was happening on the TV screen.

Tom slowly fucked his sister, both of the kids loving the sensations of sex, especially the intimacy and danger of sex with each other. The wet, sucking sound of his prick moving in his sister's sodden pussy was an additional turn on.

"You fuck so good, brother," Michelle sighed, laying her head down on her hands as she enjoyed the sex. "I wish we'd started to do this sooner. God, your cock feels sooo... good."

"I'll fuck you anytime you want," he answered his little sister, his breathing faster as his arousal grew, "just let me know. God, I love fucking you..."

Tom began to move faster, his cock slippery with wetness, the sensation of his sister's tight cunt around his prick feeling unbelievably good. He'd wanted to make this last as long as possible, but was finding the urge to cum inside his sexy little sister almost overwhelming, especially when she talked so wicked, so dirty. Losing control he stroked into her faster, harder as his climax quickly began to build in his balls. All he could think about now, all he wanted to do, was feel that wonderful, indescribable sense of pleasure and release as he climaxed inside the young girl.

Michelle was beginning her low moan, unable to be quiet through the barrage of sexual sensations building between her legs as her brother fucked her from behind, each delicious stroke of his cock coming harder and faster. She could feel her own orgasm begin to build and knew he was going to make her cum.

Tom's balls swung back and forth with his thrusting motion, becoming wet with his sister's juices each time they collided with her slit, and Michelle's great little ass added more warm tightness around his cock.

"God, I can't believe I'm fucking my little sister... , " he groaned, thrusting harder. "You feel so good... so fucking good..."

Tom was grunting above her, each penetration harder than the last as his own climax neared. His sister was so tight, so wet, he just couldn't hold back any longer. His final thrust buried his cock deep inside her as the spasms of his orgasm sent waves of pleasure over him making him grunt with the sudden hard explosion of his prick. He pushed his loins hard up against her ass wringing every ounce of sexual pleasure he could get from his climax, his back arching and a low, throaty groan exploding from his mouth as his sex cream exploded from his shaft. Five, six, seven times he could feel each spurt of his cock inside it's protective sleeve, each spasm of his now shrinking prick jolting him with waves of pleasure, even as his orgasm began to subside.
