"Sleep-over" Julie was waiting for her friend to come over to spend the night. She had lots to tell her. Last week when Julie had slept over at her friends house, and they had talked about boys and sex. Of course, this was the young girls favorite topic. Boys, sex and their own budding bodies. At 12 years old, they were just starting to develop a real interest in boys, as well as tits. "Don't you wonder what a boy's thing looks like?" Julie asked her friend, Suzie. "I know what it looks like" said Suzie. "I've seen pictures of them in books." "Not pictures, but what a real one looks like." said Julie. "Well, I haven't actually seen a real one." giggled Suzie. "Do you think it would be different?" "I don't know, but I would sure like to find out." said Julie. "Let's find out," cried Suzie. "Lets see if we can peek at our brothers when they have their clothes off." Their brothers were 16 for Suzie's brother, John, and 15 for Julie's brother, Steve. But because of the way their birthdays fell, the 2 boys weren't so far apart in age, and were in the same grade in school, and friends with each other. "Do you really think we should?" asked Julie. "You want to know what one looks like. Are you trying to chicken out?" Suzie asked. "Well, no. How can we do it?" asked Julie. "I'm going to try at peek at John when he's in the bathroom." said Suzie. "Maybe I can see something." And so the girls agreed. Each would try to peek at her brother and try to get a look at his cock. Julie had tried peeking in the bathroom when her brother, Steve, was in there, but she had not been able to. There was no keyhole, and she was too timid to try the door, afraid she would be noticed. That would be just too embarrassing, trying to explain why she was opening the bathroom door when her brother was in there. There was no way she could explain that to her parents! Then, on night, her mother had picked her up from drama practice at school and she noticed the light was on in her brothers room. After a quick snack, she told her mother she was going to her room to do her homework. She quickly finished the little she had to do, then snuck to the kitchen and out the back door. She went around to her brothers window, but it was too high, she couldn't see in. She looked around and saw the tree she used to climb when she was younger. It was right in line with window, but she never noticed when she was 7, besides, she never climbed the tree at night. She quickly climbed up to a convenient branch, and had an almost perfect view of her brothers bed. She had barely gotten into position when the light went out as her brother left the room. She quickly climbed down and snuck back into the house. The next Friday night, her parents went out leaving her and her brother alone. They watched TV for awhile, then her brother said he was going to read in his room. Julie waited for a few minutes, then quietly went out the kitchen door and back up into the tree. Bingo! Her brother was laying oh his bed reading a magazine. She watched for awhile, seeing him adjust the crotch of his pants a couple of times. Then, he unzipped his pants and took out his cock. Julie almost lost her grip on the branch, as the excitement raced through her body. She didn't know what kind of book he had, but it must be good! His cock was hard and sticking straight up. He started rubbing it as he leafed through the book. He suddenly put the book down and got up. Julie thought that would be it for the night, but before she could move, he came back with a towel. He laid back down on his bed and started reading and rubbing again. As Julie watched, he slowly rubbed his cock, increasing the speed of his rubbing. Soon, he was working it pretty fast. She saw him start to buck his hips, then suddenly his cock started jerking and she saw something squirt out, onto the towel he had laid on his stomach. After a minute, he began cleaning himself up and Julie climbed down from the tree and quickly went back into the house. Back in her room, she thought about what she had seen. Her little body was trembling slightly with the excitement of it. She wondered what had squirted out of her brothers cock when he rubbed, then realized that it must be the stuff her mother was talking about when she told Julie a little about sex. "It must be the sperm," thought Julie. Suddenly, a lot of what she had been learning about sex made more sense! Wait until Suzie came over, did she have something to tell her now. Julie had trouble getting to sleep that night. Her little slit between her legs seemed to itch. She put her hand down there and began to rub her little developing mons. She thought about what she saw with her brother and soon her belly was quivering and twitching. She kept rubbing, finally sticking a little finger up into her hot, slippery hole. That did it, her pussy exploded, sending waves of pleasure up and down her young body. She collapsed into her bed and was soon asleep. The next night Suzie came to spend the night and Julie wasted no time in telling her all about watching her brother. She described what his cock looked like, how he rubbed it, and most of all, how it squirted. The girls giggled and talked in Julie's room, their little bare pussies getting warm and tickley from all the talk. They soon began getting ready for bed, and as they did so they started comparing their small, forming breasts. They had taken everything but their panties off. So far, neither girl had much more than large mosquito bites, topped with small, pink, berry nipples. They measured each other around their tits, hoping to have grown some and wanting to see who was larger. Julie had a half inch more than Suzie, but Suzie said it was just her chest, not her tits and she was right. Neither had what could be called a handful, even for their small hands. They were soon kissing each other, trying to figure out what it would be like to be kissed by a boy. This soon lead to kissing each others little tits, tweaking the little pink nipples, making them into hard little points. They were soon feeling each others fledgeling little pussies, rubbing, then inserting a small finger inside each other and then themselves, comparing how each other felt. Then Suzie scooted down on the bed, sliding Julie's panties off and kissing her virgin lips. Julie quivered, almost fainting from the feeling, and it just kept getting better and better and better. It didn't take long before she had a small climax. Suzie insisted that Julie do that to her, so she could see how it felt. Julie didn't hesitate, she went straight for her friends hips, pulliing her tiny wet panties down, exposing her hot, slick little slit, kissing, licking, and driving her friend into throes of passion. Suzie couldn't resist her friends tongue, cumming all over it and her face. "If that's what it feels like to have sex, I can hardly wait," said Suzie. "That was really wonderful." After a few minutes rest, the girls were soon talking about boys and sex, trying to decide who was the best looking boy in their school, and who they might convince to fuck them. Suzie, slipping on a thin pink t-shirt for a nightgown, said she was going to the bathroom. She went down the hall, but instead of going to the bathroom door, she opened the door of Steve's bedroom. She was holding up her t-shirt a little, just so her pink slit could just be seen under the hem. As she walked in, she gave a little gasp and said she came in the wrong door by mistake, she was going to the bathroom. Steve was in his bed, reading the book he was reading when his sister was peeking in his window. His hard, big cock in his hand. Steve just froze for a minute, scared, not knowing what was going on at first. Then he saw Suzie didn't seem upset, in fact was staring at his cock with a funny look on her cute, young face. He stuttered, trying to think of an explanation for his condition as he tried to get a better look at the folds of flesh between her legs, just peeking out from under the t-shirt. Suzie seemed to recover, and asked Steve if the magazine had something in it that made him hard like that. Steve said that, yes, it did. Suzie asked if she could see what it was. Being very horny, and not that dumb, Steve told her to come over and sit on the bed and she could see what he was looking at. Suzie walked over slowly, finally sitting on the edge of the bed pulling the hem of her t-shirt down a bit to cover her sweet little twat. Steve showed her the pictures, starting from the front with a beautiful bikini clad model with a handsome young man in jogging shorts and tank top. Flipping to the next page, the model had removed the top of her bikini and the guy was playing with her tits. The next picture showed the guy kissing the models tits, paying lots of attention to her nipples. Steve asked Julie what she thought of it so far. Julie said she hoped her tits would be that pretty when they grew. Steve said he bet her tits would be just as nice. Maybe if he could see them he could guess if they would be as nice as the models. Suzie smiled and got up on her knees on the bed, carefully spreading them a little and lifted her t-shirt up above her navel. She gave a little gasp and dropped her shirt, saying that she had forgotten that she didn't have any panties on. Steve quickly said that it was OK, it she were completely naked he would have a better idea of what she would look like. Suzie giggled a little, and pulled off the shirt. Steve just stared at her sweet, forming, young body, rapidly glancing between her tits and her hairless little slit. For all his apparent knowledge to the young girl, he had never seen a completely naked girl so close before. Suzie asked what he thought of her titties and Steve gulped and said he wasn't quite sure yet. Maybe if he felt them it would help. Suzie agreed and Steve began caressing the girls tits. He squeezed, tweaked and rubbed them, then suddenly bent over and kissed one hard pink nipple. Julie gasped and then moaned and collasped back on the bed. Steve kept kissing both the warm, budding breasts, slowly working down to her smooth flat belly. Down he kissed, until he reached the top of her little slit. He gently spread her slim thighs with one hand, Suzie cooperating by opening her legs at the slightest pressure. As soon as her legs were spread enough, Steve put his face between her young thighs and kissed her slit. Suzie's body shuddered at the touch of his lips to the folds of her little pussy. Soon Steve's tongue was licking up and down the slit, darting between the lips into her tight, virgin hole and her tender little clit, which was standing up begging for all the attention it could get. Suzie moaned and sighed, squirming her little hips to encourage the tongue giving her so much pleasure. Steve's cock was as hard and throbbing as it had ever been. Steve knew that he would have to do something soon, or he would cum all over his bed and the cute little girl on it. He suddenly moved up, kissing Julie's tits again, then her mouth. Suzie groaned at the loss of attention to her boiling hot pussy, but the tongue in her mouth prevented her from saying anything. Then she felt a hard, hot pole hit her love lips. It slid up onto her belly, then back down between her legs, finally parting the slippery lips of her yearning pussy. It found the hot hole, and entered. One inch went in, backed out, then in again. Soon she gave a start as it hit her hymen with a pinch of pain. Then it passed through he hymen, and she felt her pussy open to the big, hard intruder. The pain ended almost as soon as it began, leaving her feeling stuffed as Steve pushed his cock half way in, only to pull it back out. Another push and it was all in, feeling like it came clear up to her throat, making her wonder how she could still breathe. They fucked and fucked, and Suzie came once, then again as she felt Steve's hard cock throb inside her, squirting her tender love hole with hot cum. They separated, and Suzie forced herself to get up, saying she had to get back before Julie came looking for her. Steve nodded, saying they could do it again later. Julie, however, hadn't waited long at all. She left the bedroom to find her friend just a couple of minutes after Suzie left. She had watched through the partly open door of her brother's room as he and Suzie fucked. When they finished, Julie dashed back to her room, trying to act calm when Suzie got back. The two girls soon went to sleep, or at least Suzie did, well satisfied after her first fuck with Steve. Julie was still very horny and couldn't sleep. She waited until she was sure her friend was asleep, then got up in the dark room and quietly left. She went down to her brother's room, tiptoed in without any lights, and softly climbed into the bed. She then gently held her brother's cock, squeezing it until he woke up. Pretending to be Suzie, she asked her bother is he wanted another fuck. Of course Steve wasn't about to pass up a chance to get into the sweet young girl's hot little hole again. He started kissing and fondling the girl beside him, kneading the young tits, caressing the delicate little pussy, getting her excited and juicy, her hips automatically heaving and thrusting. He got between her legs, slipping his cock into her dripping hole. A little push and he bumped into her cherry. "What's this?" asked Steve, turning on his bed lamp and finding his little sister under him. "What are you doing here?" he hissed. "Please Steve, I'm so hot and horny. I watched you and Suzie fuck and I just needed to be fucked, too. Please, don't be mad." Julie cried. "Won't you fuck me? Please? I can't even sleep." As a answer, Steve shoved his hard dick into his sister's horny hole, fucking into her. He pumped in and out, driving his sister wild with pleasure. she moaned and begged him to fuck her harder, harder, until she came all over his hot, pulsing cock, her hips gyrating uncontrollably against his cock. This pushed Steve over the edge and he filled his sisters no longer virgin cunt with squirt after squirt of cum. It overflowed her pussy, running down her round, tight ass cheeks and soaking into the sheets. The next morning, Suzie told her friend that she had snuck into her brother's room and gotten him to fuck her. She described the whole thing, including how it felt when his hard cock pumped her excited twat full of cum. At this, Julie couldn't resist and told Suzie how she watched, then went to her brother's room herself, pretending to be Suzie, her brother finding out it was his sister, but fucking her anyway. Suzie was shocked and excited. Her friend had fucked her own brother! How could she? But Suzie knew how she could, as her own pussy vibrated and dripped at the thought of a brother fucking his sister.
