Stories 18+ My Sister is the Bitch C1
"Robbie, you are grounded!" Ellen snapped at her son. "I can't believe you thought you could get away with something like that."

"Mom! That's not fair!" Robbie protested.

"I told you that if you forgot to take out the garbage for pickup one more time that you'd be grounded for a week. Well, you forgot. What will we do until next week?"

"But Mom, Dani was supposed to wake me," he protested. "She deliberately didn't wake me up."

"Oh, right, asshole," sneered Robbie's sister, Dani.

"Dani, I've told you about your language," Ellen admonished her daughter. "Robbie, you're still grounded and maybe next time you won't rely on anyone except yourself."

"It's not fair," he wailed, leaving the kitchen. "I'll get you!" he whispered threateningly under his breath as he walked by his sister.

"Yawnnnn," Dani said, bringing her hand to her mouth. "I'm so bored."

"You too, get out of here," Ellen told her. "You may be out of school for the day, but I have to go to work and this kitchen's a mess."

"Sure, Mom. Sorry," Dani said, pushing to her feet and leaving the kitchen.

"And don't think that I don't know that you did deliberately shaft your brother," Ellen said just as Dani was about out the door.

"I - I - I don't know what you're talking about, Mom," Dani stammered.

"Of course you do," Ellen said with a laugh. "And if I know your brother, payback is certainly going to be hell."

"I don't know what you're talking about," Dani insisted as she left the room.

But of course she knew exactly what she was talking about, because she had deliberately not woke up her brother, knowing he'd get in trouble. Now she had to worry about him paying her back and the fact that her mother really knew what had happened and she'd have no protection there either. "Oh, well," she thought, "that's life."

Robbie was in his room fuming. Dani was such a brat. Even though she was old enough to know better, she still pissed him off like only a child could. The fact that she was the most beautiful girl in school and all of his friends thought that she was a goddess infuriated him even further. They only saw her with their dicks. If they knew what she was really like they wouldn't think she was so hot. Sure, she was tall at 5'10" and had a long willowy figure with nice full tits, blonde hair down to her waist and bright blue eyes, but beneath all of that was a total fucking bitch.

Well, now she'd gone too far and payback was going to be very very serious, Robbie thought as he picked up his phone to make some phone calls. Just 15 minutes later he had finished and sat back with a smile on his face. Payback was not only going to be incredibly serious, it was going to be almost immediate.

Robbie heard his mother leave for work and then a few minutes later he heard the water running as Dani showered. Grabbing a small computer screwdriver, Robbie went to the bathroom door and quickly unlocked the door. Being as quiet as possible, he opened the door and grabbed Dani's clothes that were on the floor, as well as the towels on the towel rack before exiting and closing the door. He wasn't sure if Dani had seen or heard him or not, but he really didn't care. The only thing she could wear now when she came out of the bathroom would be toilet paper.

Quickly going to his room, Robbie got out his digital cameras, one a video camera and the other for still shots. He mounted the digital camera on its tripod and made sure both cameras had full batteries plus a couple of spares. He didn't want to run out. Going to Dani's room, Robbie put the tripod in the closet, leaving the door cracked enough for the lens to be able to see the room, pointing at Dani's bed. The still camera he just put on the dresser. He then went to the front door and unlocked it before going back upstairs and into Dani's room, where he booted up her computer and opened the file that he knew contained her diary.

Boy, was she stupid, Robbie thought as he read the past week's worth of entries. No password protection or anything. Just a nice big link on the desktop that said Dani's Diary.

Hmm, looks like she sucked Pete's dick a couple of times at school, and she let Brian play with her pussy and tits behind the gymnasium.

She sure likes sex, Robbie thought as he heard the shower stop. Here we go, he thought, sitting patiently and reading.

"Robbie! Goddamnit! Robbie!" Dani shouted from the bathroom. "You fucker!" she screamed. "I'm going to kill you!!!"

Robbie smiled to himself as he pictured her rage, then he heard the bathroom door slamming open and Dani stomping down the hall.

"I am going to kill that fucking asshole," she fumed out loud as she made her way down the hallway, naked as a jaybird.

Opening the door to her bedroom, she stormed inside, slamming the door before she realized that the object of her anger and loathing was sitting at her desk using her computer.

"What the fuck do you think you're doing?" she shouted at him.

"Getting ready to hit the ENTER key," Robbie replied, holding a finger very obviously above the key.

"So what!" Dani screamed at him. "I hate you!!!"

"Maybe you should ask me what's going to happen when I hit the ENTER key," Robbie suggested with a smile on his face, his eyes not failing to take in her nakedness.

Totally forgetting that she was standing completely naked in front of her brother, Dani asked him, "So what's going to happen when you hit the stupid key?"

"Oh, it'll only send your diary to everyone in your email address book, plus mine, plus the email list from school," Robbie said, letting his finger rest on the key.

"Oh My God!" Dani exclaimed, her face blanching white. "You wouldn't dare!"

"Actually, I would," Robbie said, letting his finger slide back and forth on the key.

"Robbie, please don't do that," Dani pleaded, real fear in her eyes.

"Why shouldn't I?" he asked. "The way you fuck with me, always trying to get me in trouble. I never do anything to you! You are such an incredible bitch to me!"

"Robbie, if you do that you'll ruin my life," Dani pleaded. "That's going too far."

"I don't know," Robbie said. "Seems to me like you're the one that likes going too far," he said with a smile and a leer at her nakedness.

"That's not fair," Dani said, blushing all over her body.

Robbie saw her nipples suddenly get hard, twisting into gnarled pink nubs that stood out proudly from her tits. Now Dani tried to cover herself with her hands, though she made no move towards the towels or clothes on her bed, just 10 feet away.

"What do you want?" she asked. "I'll tell Mom the truth, that I really did deliberately not wake you up to take out the trash," she offered. "Then she'll un-ground you."

"No, I don't think that's going to be nearly enough," Robbie said. "You need to be taught a lesson that will last you the rest of your life."

"Robbie, don't. Please don't," Dani pleaded. "I'll do anything, anything you say, just please don't send that."

Robbie was pleased to see that there were tears forming in the corners of her eyes. Served her right, he thought, resolving to be tough and go through with his plan.

"Anything, huh? That covers a lot of territory," he said.

"Anything, Robbie, anything. I mean it," Dani pleaded earnestly, feeling a slight chance of hope.

Now was the moment Robbie had thought about for two years now. He had Dani so totally in his power that she'd have to do anything he wanted if she didn't want her life completely ruined.

"Then I want you to be my slave for life," Robbie said with a completely straight face.

"You what?" Dani asked, her mouth hanging open in disbelief.

"You heard me, I want you to be my slave for life," Robbie repeated, looking her straight in the eyes.

"You've got to be joking! No! Of course not!" she expostulated, glaring at him.

"No problem," Robbie said, turning the computer chair around to face the screen once more. "I'll just send this and leave you alone......until everyone reads it, that is."

"Robbie! Stop!!! Please, don't do that!" Dani begged. "Please!"

"To you, whenever there's nobody else around, you will call me Master Robbie," Robbie told her. "The next words out of your mouth will determine whether I hit this key or not," he said, his finger poised over the keyboard.

Dani just stared at him. She couldn't believe this was happening to her. She had the perfect life. She was beautiful. Everyone wanted her. Everyone. She was always in charge. She decided what happened. And with whom. Whose dick she sucked, who fucked her, who sucked her. And she spent hours every day writing in her diary, every single detail, every single time. Even the thought that even one person had seen it, read it, made her sick to her stomach. But what if everyone who knew her read it. She'd never ever be able to show her face in town again. Her life would be ruined.

But be Robbie's slave! Oh, god, how could she!!! She just hated him so much. She didn't know why she hated him, but she hated him anyway. He was always just that much better than her. It didn't matter that she got straight A's, was captain of the cheerleaders, captain of the girls' volleyball team, Robbie had never gotten anything but an A. He'd been the quarterback of the football team since his first year and had won two state championships. He was 6'4" and always had girls hanging all over him. And he was nice to everyone. And she just hated him!!!

But now he had her. If she said no, she'd have to leave town right now. Period. But what did he mean by slave? Do his laundry? Run errands? Be nice to him instead of a bitch? How bad could it be? After all, everyone thinks he's such a nice guy, he wouldn't do anything mean to her. Would he?

For life? FOR LIFE??? What could he possibly mean? After school they'd go to college, probably meet someone and get married, have a family, move on. Maybe this is just his way to get me to leave him alone and stop being so mean.

"Robbie, please...." Dani froze at the look on his face as she began to speak and his finger moved closer to the keyboard.

Oh, god, he's serious. If I don't say what he wants to hear he'll push the key. Ohgod ohgod ohgod ohgod, what am I going to do!!! I feel sick.

"Master Robbie," Dani practically whispered.

Robbie relaxed a bit, lifting his finger from the keyboard. "Yes?"

"Master Robbie, I want to be your slave," Dani choked out.

"I can't hear you," Robbie said.

"Master Robbie, I want to be your slave," Dani said in a stronger voice, her eyes still on the floor, unable to look at him.

"And?" Robbie asked.

Dani didn't understand what he wanted. And? What did that mean. She was afraid to look at him. She was so ashamed of herself. Then she had an idea.

"For life," she said softly.

"I can't hear you," Robbie said softly. "Speak up and look at me when you talk to me."

Dani's knees were shaking as she looked up at her brother sitting in front of her computer. He had a completely neutral expression on his face as he watched her stand there, naked and basically helpless.

"Master Robbie, I want to be your slave for life," Dani managed to say, keeping her eyes on his the whole time.

"And do you know what a slave is?" Robbie asked.

"Y-y-yes.....no.....I don't know," Dani finally said.

"That means I own you. Totally. I tell you to do something, you do it without any further thought. Period. I tell you to not do something, you don't do it. Period. Forever. Do you understand that?" he asked.

Dani stared at him. She couldn't believe what she was hearing. This was like backwards time travel. A slave! What was she getting herself into?

"Yes," Dani said, "M-m-master," she finished, seeing his eyes narrow.

"Fine," Robbie said, turning to the computer. "Come stand over here," he told her.

Dani quickly walked over and stood slightly behind her brother as he sat at the computer. Looking at the screen she saw that it was indeed an email with the file name of her diary as an attachment, only it wasn't addressed to all of the people he had said, it was only addressed to him.

Robbie pressed the ENTER key, sending the email, and Dani gasped.

"Why did you do that?" she demanded. "You said you wouldn't!"

"Don't you ever talk to me like that again," Robbie told her, turning to look at her. "You are a slave. Slaves don't question anything about their masters. Do you understand?"

"Yes, Master," Dani hissed after a moment's pause.

"But to make you feel better, I sent myself a copy of your diary. Now if you delete yours, which I now forbid you to do, I'll still have a copy. Which I can send to whomever, whenever I want. Which I will do if you're not the perfect slave......forever."

"Oh, god," Dani moaned, putting her face in her hands.

"You don't have to call me that, Master will do," Robbie said, laughing.

"It's not funny," Dani said, adding, "Master," after he glared at her.

Robbie stood up then, putting him front to front in physical contact with his naked sister. Dani gasped and started to step back, but Robbie grabbed her by one arm to stop her, his other hand moving to cup and hold one of her tits, squeezing it and then pinching the nipple between his fingers before releasing her.

"Robbie!" Dani exclaimed.

Robbie glared at her.

"M-m-master," Dani stammered, unable to get her mind used to the change. "I'm your sister."

"You're my slave," Robbie corrected her. "Anything else is just incidental now."

"R-r....Master," Dani began, "that's.............illegal," she finally said.

"Anytime you want to stop being my slave, all you have to do is say I AM FREE three times and you'll be free. But then I'll feel free to do what I want with your diary. As long as you're my slave, you and I are the only ones who will ever see your diary. As soon as you decide you want to be free, that can change," he told her. "So it is really up to you. Whatever happens is going to happen of your own free will, by your decision and agreement. So you need to make up your mind," he told her.

Dani just stared at him, not six inches separating them, he dressed and she totally naked, brother and sister.

"Yes, Master," was all she said.

Robbie nodded, seeing that she had finally accepted her new situation. He then slowly pushed his shorts down to the floor, standing naked but for his t-shirt in front of his shocked sister. He then sat back down in the chair in front of the computer and picked up his still camera, looked through it at his sister and snapped a shot.

"W-w-what are you doing, Master?" she asked.

"You're so beautiful, I just had to have a picture of you," Robbie told her. "I'll email I to you so you can put it in your diary."

"M-my diary?" she asked.

"Yes, your diary. I really like the way you write. You really pay attention to the small details. I want you to continue your diary, just like you always have, only now you'll have something more, something new to put in it. And I'll take pictures for you so you can include them. That'll make your diary really special."

"Oh!" was all she managed.

"Now I want you to beg me to let you suck my dick," Robbie told her.

"Master!" Dani said, her eyes wide.

"And it better be very very believable," Robbie told her. "If anyone is listening to us, I want them to believe you are really begging. Right now!"

"Oh, oh, oh, Master, I - I - I......oh, Master, I....can I......Master, please let me suck your cock," Dani finally managed to get out.

"What was that?" Robbie asked, watching her through the camera.

"Master, please, let me suck your cock," Dani said.

"I don't know," Robbie replied. "I'm not sure I'm in the mood,"

"Oh, Master, please. Please let me suck your cock." Dani said, this time with some feeling in her voice.

"Do you really want to?" Robbie asked.

"Oh, Master, yes, I really want to. I want to suck your cock. I want to taste your...." Dani said before catching herself and stopping.

"Yes? You want to taste what?" Robbie asked.

"Master, I want to taste your cum," Dani said in a small voice.

"You like cum, Slave?" Robbie asked.

"Yes, Master," Dani replied, blushing.

"Then suck my dick until I cum in your mouth," Robbie told his sister.

"Yes, Master," Dani said, sinking to her knees in front of him.

For the first time Dani really looked at her brother's cock and with a shock realized that he had a really nice one. Even mostly soft it was at least 6" long and very thick. With Robbie watching her through the camera, Dani reached out and took her brother's cock into her hand for the first time. Almost immediately it began to grow harder in her hand as she instinctively began to jerk him, helping him get hard. In just a matter of seconds it was rock hard and at least 10" long and thicker than any cock she had ever seen. She couldn't believe that it more than filled both of her hands.

Robbie was taking pictures the whole time as Dani knelt between his legs and began to play with his dick. The look on her face when she saw him hard was a great picture, as was the one when she first leaned forward and tasted the slit of his dick with the tip of her tongue. Then she was swirling her tongue all around the head of his cock, licking up and down his shaft, sucking on his balls, until she finally locked her lips around the head of his cock and began lowering her mouth onto him, initially taking almost 6" into her mouth before sliding back and doing it again.

Dani fucked her face with her brother's huge cock like this for several minutes, frequently stopping to swirl her tongue around the head and into the slit before going back down on him. Finally she took him into her mouth until the head of his cock was pressing at the entrance to her throat. As big as he was, Dani was somehow able to get her throat to relax enough for her to force herself down on his cock, pushing it into her throat until her face was pressed up against his belly.

She instinctively gulped and Robbie groaned, feeling her throat flex around his cock. Then she drew back until just the tip of her tongue was resting in the slit of his cock before sliding back down again, once more taking him into her throat. Dani felt her pussy getting wet as she sucked her brother's huge cock. It tasted so good and filled her mouth like no cock had ever done before. 

Even though she was young, Dani had already given over 100 blowjobs. She kept count. She had fucked 7 different guys, two of them more than once. And she had let two of them fuck her in the ass, also more than once. And now she was sucking the biggest, most beautiful cock she had ever seen and it belonged to the brother that she had hated more than life itself up until this minute. And now she was on her knees sucking him off in her own bedroom and loving it.

Robbie felt his balls begin to churn and knew that he was close to cumming. He also knew that he wasn't ready to cum yet. Reaching down he lifted his sister's face from his dick.

"Just a second," he told her. "I want better light for the cum shot. When I'm ready I just want you to open your mouth and stick out your tongue," Robbie instructed her.

"Yes, Master," Dani gasped, her eyes wide with excitement. She couldn't wait to taste her brother's cum.

Robbie adjusted the chair so that he was facing the door and Dani scooted over to continue kneeling between his legs, his cock sticking straight up in the air. They heard the sound of a car horn going off in the distance.

"Okay, keep going," he told her.

Eagerly Dani grabbed her brother's cock and began licking and sucking on him again and in no time had him buried deep in her throat. Robbie groaned as he continued to take pictures. Just as he felt his balls beginning to tighten again Robbie saw the door to Dani's bedroom slowly open. What little noise it made was more than covered up by the sounds of Dani sucking his dick.

Two of Robbie's best friends from school, fellow football players, were standing in the door looking at Dani's naked back as she knelt between Robbie's legs sucking his cock. They couldn't actually see anything, but it was obvious to them what was going on. They stood there silently until Robbie groaned and put his hand on Dani's head.

"That's it, I'm cumming now," he said, holding the camera with one hand and continuing to snap pictures, while with the other hand he held his cock, jerking it as the head lay on Dani's outstretched tongue. He groaned loudly as the first shot of cum spurted from his dick all the way into his sister's open mouth. His cock kept spurting cum, covering her tongue and dripping down the sides of her mouth and her chin. When he finally stopped cumming, Dani's tongue was covered in a pool of cum and her whole face below her nose too.

"Now suck it and swallow all of it," Robbie told her.

Not needing any encouragement at this point, Dani went completely back down on her brother's cock, taking him directly into her throat and sucking hard on him with her whole mouth. Robbie groaned and continued taking pictures as his friends stood by the door with big grins on their faces. Finally Dani stopped sucking on him and sat up, his cock still hard and gripped firmly in her hand.

"Let me help," Robbie said, taking his cock in his hand and wiping the cum from his sister's face with it, then offering it to her open mouth where she sucked it off.

"That was great," Robbie sighed, sitting back in his seat. "You really know how to suck dick."

"Yes, Master," Dani said with a smile.

"I'll bet you'd like to suck some more, wouldn't you? Eat some more cum, wouldn't you?" Robbie asked.

"Oh, yes, Master," Dani said, a big smile on her face.

"Then I think that's just what you'll do," Robbie said, getting to his feet, his cock slapping her in the face. "John and Brett are here to help you make yourself happy," he told her, looking over at them.

Dani gasped and looked over her shoulder and saw John and Brett standing there, big grins on their faces.

"Robbie!!" Dani began before stopping when she saw the look on his face.

"Try to make them both cum at the same time," he told her. "And remember, this is what you want, so you better act like it."

Dani stared at him for a moment before turning to look at John and Brett, both of whom she knew but had never been out with.

"Why don't you guys undress and sit on the edge of the bed," Robbie suggested.

It didn't take them long to strip and sit on the bed, their cocks dangling in front of them. John's cock was as big as Robbie's and jet black, like the rest of him, while Brett's cock wasn't as long, but it was even thicker around. Robbie stood behind Dani, his semi-hard cock poking her in the back.

"Make it really good, Slave," he whispered into her ear. "I want to see cum all over your face and filling your mouth," he said, reaching down to caress her ass cheek.

"Yes, Master," she whispered back to him, dropping to her knees.

"Mmmm, I just love sucking cocks," Dani said, taking them both in her hands. "And I'll bet you two are going to cum buckets too, aren't you?" she asked, leaning forward to lick first one, then the other cock.

Robbie was very busy with the camera taking pictures as his sister began to suck off his two friends. Just like she had done with him, she licked each of them all over before sucking them into her mouth, then her throat. They were both groaning in no time, Dani's talented mouth bringing them quickly to the point of no return.

"Oh, god, I'm gonna cum," Brett moaned while his cock was buried in Dani's throat.

Dani pulled off of him, turning again to John and swallowing his cock, continuing to pump Brett's cock with her hand. She quickly had John at the point of orgasm too and left him, returning to suck on Brett once more. After just a few seconds he was groaning as he began to lose control of his balls. Jerking Brett's cock furiously with her hand, Dani began sucking John's cock once more, taking him all the way into her throat as the first of Brett's cum shot from his cock into her face. Turning from John, Dani opened her mouth and aimed Brett's cum onto her tongue, even as she pumped John. Then John began spurting cum onto Dani's face and the two of them were covering her. She held both of their cocks to her mouth, trying to suck them both at the same time as they continued to spurt cum. She had to swallow twice as her mouth filled up before finally sucking first one, then the other, getting the last of their cum before scooping up the cum from her face and licking it off of her fingers.

"God, that was great!" Brett said, staring at Dani. "I never dreamed anyone as beautiful as you would be sucking my dick."

Dani just kept swallowing, trying to get all of the sticky, salty cum out of her mouth. She had never eaten so much cum before and her mouth was all clammy.

"Here, suck me for a bit while they get dressed," Robbie ordered Dani.

Dani stared at him for a moment before turning on her knees and taking his cock in her hand, opening her mouth and swallowing him. Brett and John slowly dressed, not wanting to miss the sight of the most beautiful girl in the world sucking her brother's cock.

"See you guys later," Robbie said when they had finished dressing, his cock buried in his sister's mouth. "Thanks for stopping by."

"No sweat, Robbie," John said. "Anytime, anytime at all."

"Yeah, me too," Brett chimed in. "I'm in heaven."

Dani was totally involved in sucking her brother's cock when they left. Her mind was spinning. The taste of cum filled her world, just like her brother's cock filled her mouth and throat. She hated him, she really did. But she loved his cock even more than she hated him, she realized, sucking even harder.

Then Dani felt her brother grab her hair and slowly pull her up and away from his cock. She felt a momentary panic. She wanted, no, needed another mouthful of his cum. Without saying a word, Robbie led his sister by the hair over to her bed where he positioned her so that she was on her hands and knees, her ass and pussy pointed right at the closet.

"So, Slave, what do you want?" Robbie asked, rubbing his sister's ass cheeks.

"Oh, Master, I want to suck your cock. I want you to cum in my mouth again," Dani moaned in reply.

"I see," Robbie said, letting one hand slide between Dani's ass cheeks, his finger sliding over her puckered asshole and between her pussy lips, feeling how drenched with juices she was.

"Maybe I will let you suck my cock again," he said, now rubbing his cock up and down her slit, feeling the heat emanating from her as the head of his cock quickly became slick with her juices.

"Oh, Master," Dani moaned, feeling more excited than she had ever felt in her whole life. 

"Oh, Maaassstterrrrr," she groaned as Robbie slid his entire cock into her in one steady push, stretching her young pussy to its maximum as he buried himself deep in his sister.

Robbie couldn't believe how hot and tight and wet his sister's pussy felt. It was like magic. He had certainly fucked his share of girls, being so popular and girls wanting to be with, especially seen with, somebody popular. So getting pussy was not that new to Robbie. But the feeling of his sister's pussy was blowing his mind. It was like it was alive, writhing on his cock as he steadily fucked her.

Dani was moaning, her face in her arms as she knelt on the bed, her ass up in the air, her pussy impaled on her brother's big cock. This was the best fuck she had had yet, she thought as her pussy stretched to accommodate her brother's pounding cock. She gasped when Robbie suddenly pulled his cock from her pussy and spun her around to sit on the edge of the bed, his rock-hard cock glistening with her pussy juices in her face.

"Suck it now, Slave," Robbie told her, grabbing her hair and pulling her face towards his cock.

But Dani needed no encouragement any more. She couldn't wait to get her mouth wrapped around her brother's cock again. As she felt him slide onto her tongue to the back of her throat, Dani tasted herself for the first time. She had never sucked any of the boys who had fucked her after they had fucked. This was the first time. And it was a strange but wonderful taste. She closed her lips around his shaft and sucked with her whole mouth, letting her tongue slide all over him, tasting her juices.

Then Robbie gently began fucking her mouth, sliding his cock in and out, stopping at the back of her throat and then sliding back out to where just her lips and tongue were in contact with the head. And then he pushed against her throat and Dani swallowed, taking his cock down into her throat until the whole thing was buried. She sucked with her mouth and continually gulped with her throat, milking him.

Robbie groaned and pulled Dani's hair so that her face was tilted upwards as he slid his cock from her throat and mouth.

"Open your mouth and stick out your tongue," he told her.

Just as Dani's tongue slid out of her mouth Robbie exploded, cum shooting into her mouth and then covering her tongue. He slid his still spurting cock into her mouth and Dani wrapped her cum-covered lips around his shaft and began sucking on him, drinking and swallowing his cum, probing the slit it was shooting from with the tip of her tongue, driving him out of his mind. Dani sucked him and licked him until there was no more cum for her before stopping, her lips swollen, her face smeared with cum as she looked up at him.

"Thank you, Master," she said, a sly smile on her face.

Robbie stared at his sister, not believing what he was seeing. She was actually enjoying this. He could probably give her back the diary and she would still let him do whatever he wanted. But that would be stupid. His mind was awash with the possibilities open to him if Dani would indeed be his slave.

Turning and walking to the closet, Robbie opened the doors completely, revealing the video camera mounted on the tripod. He turned it off and took it from the closet. Dani sat with a stunned look on her face. It was one thing to have done what she had done for the past couple of hours, but to think that it had all been video taped was entirely different.

"W-what is that, Master?" she asked in a small voice.

"I knew you'd want a permanent memory of your conversion from free woman to slave, so I taped it for you. All of it."

"But what if someone sees it, Master?" she asked.

"Nobody would be able to see it unless I let them see it," Robbie replied. "And why would I want to do something like that?"

He really had her now, Dani thought to herself as she stared at him. Even though she would now happily and willingly play this game with him, without a doubt she was completely and totally in his power now.......and forever, as long as he had her diary and the video....oh, god, and all of those pictures he took with the camera.

"Yes, Master," Dani said softly, dropping her head in resignation.

"Bring my clothes," Robbie commanded, picking up the camera from the desk before heading for the door.

Dani started to reach for something to put on when Robbie interrupted her.

"You don't need clothes. In fact, when it's only you and me in the house, you are to be naked. All the time. Understand?"

"Yes, Master," Dani replied, gathering his clothes from the floor and getting to her feet and following him down the hall to his bedroom.

"I want you to go work on your diary now," Robbie told her. "I'll send you the pictures and you can use whichever ones you want. You can even include video clips when I edit them. When you're finished, you are to email me your diary. Every time you write in it, when you're finished, you are to email me your diary. Do you understand?"

"Yes, Master," Dani replied.

"Now throat me one more time and go work on your diary," Robbie told her.

"Yes, Master!" Dani said, a smile on her face as she dropped to her knees and grabbed his cock in her hand. "Yes, Master," she said as she opened her mouth and engulfed him, quickly getting his entire cock in her mouth and sucking on him.

"That's good," Robbie said, pulling his cock from her mouth to her obvious disappointment. "You can go now."

"Yes, Master," Dani said, getting to her feet and leaving the room.

Robbie flopped down in his computer chair and let out a long sigh, not knowing that Dani had paused outside of his door and listened for a moment before continuing to her own room.

That was absolutely incredible, Robbie thought to himself as he extracted the memory stick from his camera and inserted it into his memory stick reader to copy the picture files he had just made to his computer. It was so easy, he thought as he copied the pictures to a new folder, all 48 of them. And she totally loved it, he thought as he then sent them with an email to Dani. DSL sure is great, he thought as he remembered how it felt to cum in her mouth that first time, seeing her face covered with his cum, watching her swallow it all.

Oh My God, Dani thought as she went back to her room, closing the door behind herself. I can't believe what just happened. I was a total slut, she thought. And with my own brother. Oh, god, and I sucked his two friends too. Oh, when he pushed his cock into my pussy I thought I was going to die it felt so good, she remembered. God, my face is still covered with cum, she realized as she felt the dried stuff caked all over her cheeks and chin. There was even some on her breasts that had dripped from her chin. And she had dried pussy juice all over her inner thighs.

Dani sat down at her computer and opened her diary. But she couldn't type anything. It's different now, she thought. Now I know someone else is reading. How can I possibly be so open, so honest when I know he's reading everything. She tentatively started typing and when she finally stopped, an hour had gone by. She emailed it to her brother and then went to take a shower.

"Where are you going, Slave?" she heard as she passed Robbie's room.

"M-master, to take a shower," Dani replied.

"Did you do your diary?" he asked.

"Yes, Master. I just emailed it to you."

"Wait right there, I'll read it," Robbie told her.

"Master, I need to take a shower. Mom's going to be home soon and I'm covered with dried cum," she said, a smile creasing her face.

"Go ahead, then," Robbie told her. "I'll read it while you're in the shower."

"Thank you, Master," Dani said in a dramatic voice, laughing as she went down the hall.

Robbie smiled to himself as he checked his email. This was just perfect! There was absolutely no nastiness or resentment or anger from Dani about anything. Now she was behaving like the perfect sister, albeit his sex-slave sister. Robbie opened the diary entry Dani had sent and quickly read it, then sat back in his seat in disgust, waiting for Dani to finish her shower. Ten minutes later he heard the bathroom door open and Dani coming down the hall.

"Come in here," he commanded.

"Yes, Master," Dani replied, entering his room, a towel wrapped around her.

"What's that?" Robbie asked, nodding towards her.

"Master?"

"I told you that you are to be naked whenever we are alone in this house. What part of that do you not understand?" Robbie asked as Dani stared at him wild-eyed. "This is not a game. You are my slave. You might like it sometimes, but my slave you are. Do you understand that?"

"Yes, Master," Dani said, letting the towel fall to the floor.

"Now come over here," Robbie told her.

Dani quickly moved over and stood next to him.

"What is this crap?" Robbie asked, indicating the open diary entry.

"Master, my diary," Dani replied.

"Bullshit," Robbie said. "You write much better than this. This is flat, not descriptive, no mention of how you felt when everything happened. Not your usual way of writing. This is not acceptable."

"Master, it's so hard to write like that when I know you're reading it. It was supposed to be a private place where I could be honest with myself. I never intended anyone else to read it," Dani told him.

"That's all changed now. You are to write the same and I will read it. And I told you to use pictures. Everywhere you describe something and there's a picture of it, use a picture. I want it to be as visual as well as descriptive."

"Yes, Master," Dani sighed, realizing that this might not be that much fun.

Standing up, Robbie leaned over and sucked one of Dani's delectable nipples into his mouth, his hands coming up to caress and squeeze her breasts.

"Oh, Master," Dani sighed, one hand resting softly on the back of his head as he suckled her.

"What am I doing?" Robbie asked, stopping for a moment.

"You're sucking my tit, Master," Dani replied, wishing he would continue.

"No, describe it for your diary. Say it for your diary while I'm doing it," Robbie instructed, once more sucking her now hardened nipple into his mouth.

"Oh, Master is sucking my tit," Dani began as Robbie gently bit down on her nipple, causing her to gasp.

"Mmm, he's biting my hard nipple. I can feel his tongue teasing the tip of my nipple and his hand is squeezing me. It feels so nice. Ahhh, now he's doing it to the other one," Dani sighed. "Oh, he bit my nipple hard and it hurt a little and now it's so hard and he's just sucking and chewing on it," Dani described. "And my pussy is getting so wet and I want his cock so bad," Dani panted.

"That's better," Robbie said, standing up and looking at her. Her nipples were both rock-hard and standing out a half an inch from her full tits. He could see moisture glistening on her pussy lips, which he realized for the first time were absolutely hairless. Her whole slit was clearly visible. She must have shaved when she took a shower.

"Turn around," Robbie told her, sitting down.

Dani turned her back to her brother, standing astradle his legs. She knew he could easily and clearly see her freshly shaved pussy and she wondered what he was going to do to her.

Robbie glanced at the clock. Their mother was due home from work at any moment and then he'd have to behave.....at least for a while. But for the moment...

Dani gasped when she felt her brother's hands on her ass cheeks, squeezing them and then pulling them apart, spreading her ass and pussy open to his gaze. Then she felt him pulling her downwards with one hand on her hip, so she began to squat down, squealing with surprise and delight when she felt his cock sliding between her pussy lips. She continued sitting down until she felt his entire cock ensconced deep in her pussy, filling her. She felt Robbie's hands reach up and wrap around her, grabbing her tits and pulling on her hard nipples as she began to bob up and down on his cock.

"Kids, I'm home," they suddenly heard from downstairs as Ellen arrived home from work.

Dani instinctively tried to jump up off of her brother's cock, but Robbie grabbed her tits firmly in his hands, holding her firmly on his cock.

"Answer her," he told her. "Now."

"Uh, up here, mom," Dani managed as Robbie resumed fucking her.

"Okay," they heard, then her footsteps on the stairs.

Dani stared in horror at the open door, feeling her brother's cock sliding in and out of her pussy. Then Robbie released her and she bolted for the door and down the hall into her own room, just as her mother got to the top of the stairs. She stopped at the entrance to Robbie's room and noticed that he was sitting at his computer with a towel around his waist.

"Hi, Robbie," she said. "Everything okay?"

"Hi, Mom," he replied. "Yeah, fine. I've been working and I'm going to take a shower now," he told her, getting to his feet.

"I'm going to change myself," Ellen told her son, noticing that his towel was tenting quite a bit in front. "I wonder just what kind of studying he was doing?" Ellen wondered as she went to Dani's room, knocking and opening the door all in one motion.

"Hi, Dani," she greeted her daughter. "Everything okay?"

"Oh, hi, Mom," Dani greeted her mother, turning from the mirror of her vanity where she had been brushing her hair in her robe.

"Did you behave with your brother today?" she asked.

"Yes, Mom, we were fine. I'm sorry I've been such a bitch. I'll try to be better," she offered.

"That would be nice, dear," Ellen said, turning to leave.

Well, at least it seems there was peace here today, Ellen thought to herself as she went into her room where she quickly undressed and stepped into the shower. Maybe they're finally growing up. That was quiet a blow-up this morning, worse than usual, she remembered.

She finished with her shower and dried off, then went into her bedroom to dress. Stopping to bend over and pick up her clothes she had just dropped on the floor, she sensed or heard something and stood up, turning around. To her surprise she noticed that she hadn't closed the door completely and that it was 6-8 inches open and that Robbie was just moving away from her room towards his own across the hall. If he had been standing in her doorway he would have seen her come out of the shower naked and then a clear view of her ass and pussy when she bent over to pick up her clothes.

Oh, god, just what I need, she thought as she pulled on running shorts and a t-shirt and glanced at the mirror as she was leaving the room. What am I thinking, she thought as she looked at herself in the mirror.

Ellen had always been a beautiful woman, having been homecoming queen in high school before going to college and meeting and marrying Joe. As she looked at herself in the mirror now, she saw that her 36D breasts were almost completely visible through the t-shirt, which also seemed to be a size or two too small. She had large nipples and they were sticking out prominently through the t-shirt. At 5'10" tall, she still had nice long legs without an ounce of excess fat on them, due to the constant aerobics classes she took each evening.

Oh, you're just being silly, she told herself as she left her room. She always dressed very casually around the house and there was no reason to change that now. Joe would be home in about 30 minutes, so she had to get dinner ready, she thought to herself as she went to the kitchen, forgetting about what might have been just a few minutes earlier.

Wow, what a body! Robbie had never seen his mother naked before, though the way she usually dressed around the house left very little to the imagination. But actually getting to see the parts that were usually left to the imagination was something else indeed. Actually seeing her naked tits with the huge nipples was different than seeing them through a t-shirt or the tiny bikini she wore when she sunbathed. But it was when she had bent over to pick up her clothes and he had seen her pussy that he had almost stopped breathing. She had the fattest pussy he had ever seen, with her inner pussy lips sticking out almost an inch from between the fat, puffy outer ones, and her clit had bulged at the top of her slit. He wasn't sure if she had noticed him at her door or not as he moved away, but his cock was still rock-hard from the sight.

The dinner was uneventful except insofar as Robbie and Dani did not exchange even one unpleasant or unfriendly word. Robbie couldn't stop himself from taking surreptitious glances at his mother's tits. Now that he had seeing them, he couldn't stop picturing them, especially the big hard nipples. After dinner Robbie opted to watch television with his parents while Dani excused herself, saying that she needed to work on her diary.

"You sure spend a lot of time with your diary," Ellen said to her daughter.

"I just know when I'm older it will be so much fun to be able to read and remember and re-live all the things I did when I was young," Dani said. "So if I want to get all of the details, it takes time."

"How come you don't keep a diary?" Ellen asked Robbie.

"I'd never leave the evidence written down like that," Robbie replied with a laugh.

The movie they were watching ended at 11:00 and they all got to their feet, stretching.

"Well, goodnight, Robbie," Ellen said to her son, putting a hand on his shoulder as she leaned over to kiss him goodnight on the cheek.

"Goodnight, Mom," Robbie replied, trying not to blush as he felt one of his mother's breasts lightly rub against his arm as she kissed him.

"You and your sister have the whole week off from school, don't you?" Joe asked his son.

"Yes," Robbie replied.

"It's a shame that you have to spend the entire week being grounded," Joe said, "but I think this will teach you a lesson that we will not have to revisit in the future."

"I think I can practically guarantee that," Robbie said as he went to his room.

Robbie went to his room and did a video capture of the day's activities and began to edit it, making sure it reflected exactly what he wanted it to, his sister begging him for sex and then begging his friends too. It was incredible footage, as good as any he had ever seen, and he couldn't stop smiling as he finally finished, then emailed it to his sister.

He had heard his parents almost an hour ago going to bed and he now peeked out from his door towards theirs across the hall and saw no light coming from under the door. Tip-toeing across the hall, he put his ear to the door and heard nothing, so he knew they were asleep.

A smile on his face, Robbie went to his sister's door and let himself in without knocking, quietly closing the door behind himself. It was dark and he could see his sister in her bed, a sheet pulled up over her. Quickly removing his shorts, Robbie went to the side of the bed and suddenly grabbed the sheet and pulled it off of Dani, revealing her in a t-shirt and panties, suddenly jerk awake.

"R-r-robbie!" she exclaimed in surprise. "What are you doing?" she asked, suddenly noticing his hard cock standing out in front of him and pointing at her.

"Slave," he said, emphasizing the title, "suck my cock. I want to cum."

"M-m-master," Dani stammered, struggling to come awake. "What about mom and dad? They'll hear."

"No they won't," Robbie told her. "They're asleep. And I didn't ask for a discussion. Suck it now!"

Dani sighed and sat up, reaching for her brother's rock-hard cock.

"Wait," Robbie told her. "Take off your clothes first. In fact, you are to sleep naked from now on. There's no excuse for you to wear any clothes when you go to bed. That way when I want a blowjob or to fuck you or whatever, I won't have to wait for you to get undressed."

Silently Dani removed her t-shirt and panties before reaching once again for her brother's cock. Once she had her hand wrapped around it, she couldn't wait to get her lips wrapped around it. It was just the most magnificent cock in the world to her and somehow she was able to ignore who it was attached to.

Robbie watched with satisfaction as his sister sucked his cock, loving it when she went totally down on him, taking his entire cock deep into her throat. He felt his balls begin to churn and wasn't yet ready to cum, so he pulled his cock from her mouth, leaving her gasping.

"Lay back," he commanded, stroking himself.

Dani lay back on her bed, automatically bringing her knees up to her chest and spreading them, opening her pussy wide to her brother. Robbie rubbed his cock up and down Dani's wet slit a few times before finally sliding into her hot tight hole. He fucked her for about a minute before his balls once more started churning. Pulling his cock from her pussy, he pulled her into a sitting position and stuck it in her face.

Dani opened her mouth and sucked on him again, this time tasting her own pussy once more on his shaft. She had decided that it was a good taste and made it all the better. Almost immediately Robbie started cumming, shooting cum into her mouth which she quickly gulped down, continuing to suck on him, trying to get all of it. When he finished cumming, Dani stopped, sitting up and wiping her mouth with the back of her hand as she continued to swallow his cum.

"When you get up in the morning, you come suck me off before you go to the bathroom," Robbie instructed her. "Every day. Do you understand?"

"Yes, Master," Dani replied as she looked up at him.

Robbie picked up his clothes as he left his sister's room, a big smile on his face as he walked naked to his room next door, dropping his clothes on the floor and collapsing on his bed, sprawled on his back.

He awoke the next morning to the incredible sensation of a hot wet tongue on his quickly growing cock. Opening his eyes he saw his sister kneeling next to his bed, one hand wrapped around his cock while she began to suck him off. He ran his fingers through her hair as she took all of him into her mouth, sucking and milking him with her mouth and throat.

"Climb up here and let me suck your pussy, Slave," Robbie said to her.

Without releasing his cock, Dani swung herself up onto the bed, settling her soaked pussy right on her brother's face. Robbie stuck his tongue up into her sweet hole, drinking her juices as she continued to suck his cock.

Dani was squirming around on his face as he sucked her pussy, holding her clit between his lips and teasing it with his tongue. Robbie felt his balls churning as Dani continued to suck him and he knew that he wasn't far from cumming. Just as he felt his balls begin to spasm and cum start to shoot through his cock into his sister's mouth, Robbie jammed three fingers deep into Dani's pussy, causing her to begin to have an orgasm at the same time she was struggling to swallow all of the cum he was pumping into her mouth. When she had finished sucking the last drop of cum from his cock, Dani rolled over onto her hands and knees on the floor next to his bed.

"Was that what you had in mind, Master?" Dani asked, licking her lips as she stared at him.

"That's exactly what I had in mind," Robbie told her, sitting up, his less than hard cock dangling in front of him. "You can go get ready for school now," he told her.

"Thank you, Master," Dani said, getting to her feet.

"Don't forget, I want to read your diary every day," Robbie admonished as she walked to the door, her naked ass swaying enticingly from side to side.

Robbie sat on the edge of his bed shaking his head in wonder as Dani left the room for the bathroom. He heard his parents' door open just as the bathroom door closed and smiled to himself at the reaction Dani leaving his room naked would cause. Then realizing that his door was wide open and that his parents would be able to see in, he jumped up to close the door, his hand grabbing it just as his mother stepped out of her room.

They both froze for a moment, Ellen staring at her son's cock hanging down in front of him half hard still. Then Robbie shut the door, his face burning at the thought of his mother catching him like that.

Oh my god!!! Ellen thought as she went to the kitchen. I cannot believe what a cock my son has. Even half hard he was bigger than his father. How am I going to face him now? That was so embarrassing.

Joe came into the kitchen and took the proffered cup of coffee from Ellen, kissing her on the cheek as he thanked her. She tried to tear her mind from the sight of Robbie's cock as she began to put breakfast on the table. Dani came in wearing a mid-thigh length bathrobe, a smile on her face and a bounce to her step, kissing first her mother, then her father before sitting down at the table.

"My, aren't you in a good mood!" Ellen commented.

"And why not?" Dani retorted.

"And why not indeed!" Ellen agreed, shaking her head.

You just never know with kids, she thought. Then Robbie entered the room and she froze, for only a few seconds, but she froze, her eyes locked with his before he averted his eyes and sat down at the table between Dani and Joe.

"Morning," he said, filling his plate.

"So, you think you and your sister can manage another whole day without killing each other?" Joe asked.

"We'll find a way," Robbie replied. "Maybe I'll just make her my slave for life and then there'll be no more problems."

Dani choked on her food as Joe and Ellen laughed and Robbie sat there with a straight face.

"I can't imagine Dani as anyone's slave," Ellen said. "Way too much spirit. Maybe the other way around," she said.

"What do you mean?" Dani asked.

"Just that you're more likely to make Robbie your slave than the other way around."

"Now that's an idea," Dani said with a smile.

"I'll see you all later," Joe said, getting to his feet. "Maybe if you two can actually show us that you're getting along, we'll cut the grounding short so you can enjoy part of your vacation week.

"No problem," Robbie said.

"Yeah," Dani agreed, nodding.

"Joe, you forgot your bag," Ellen shouted, grabbing it off the counter and hurrying after him.

As soon as she was out of the room Robbie reached over and pulled Dani's robe open, then slid his hand down between her legs and jammed two fingers into her pussy.

"Oh, god," Dani gasped in shock.

Hearing the car door close, Robbie removed his hand, bringing his fingers to his mouth where he sucked on them as Ellen re-entered the room. Dani hastily tried to shut her robe but didn't wholly succeed, one of her breasts almost completely visible.

"Well, I'm going to get ready for work," Ellen said, her eyes suddenly registering the fact that Dani's breast was exposed and that her bathrobe wasn't quite covering the rest of her either.

She saw Dani arrange her robe and everything was as it should be, but Ellen couldn't help thinking about it as she went to her room to shower and get dressed for work.

Robbie got to his feet and pulled his cock out, grabbing Dani by the hair and pulling her face to him. He watched with satisfaction as she opened her mouth and sucked his cock.

Ellen had undressed and was getting ready to step into the shower when she suddenly gasped. Quickly opening the door and stepping into the hall, she called out, "Robbie, Dani, I forgot to turn off the stove. Will you please do it?" Then realizing that she was totally naked, she ran back into her room and into the bathroom where she got in the shower.

When Robbie and Dani heard their mother call out, Dani had automatically tried to stop sucking her brother's cock while Robbie had gripped her hair even tighter, holding her face against his stomach, his cock down her throat as he replied, "I got it, mom."

Dani stopped struggling against her brother and he eased his cock from her throat. Gasping for breath she licked the head of his cock, sticking the tip of her tongue into his pee slit while her hands cupped his balls and stroked his shaft.

"Stand up!" Robbie ordered.

Flustered, Dani released his cock and stood up in front of him.

"Take off your robe!" Robbie ordered.

"But Mom..." Dani began, then stopped when she saw the look on his face and shrugged out of her robe, standing naked in front of him in the kitchen.

"Turn around," Robbie ordered, getting to his feet. "And bend over and grab your ankles."

Dani did as she was told, presenting her ass and pussy to her brother. She felt his hands on her hips, then his cock pressing into her pussy.

"Oh, god," she groaned as her brother's cock filled her pussy.

"Nice tight pussy, Slave," Robbie said, pumping his cock in and out of his sister's pussy.

"Y-y-yes, Master," Dani gasped, struggling to keep her balance and wondering how they would ever be able to explain this if their mother were to walk in on them.

"I'm going to cum on your face, Slave," Robbie informed her.

"Yes, Master," Dani gasped.

Robbie fucked her hard, slamming his cock into her. Then he suddenly pulled his cock out of her pussy and spun her around onto her knees in front of him. Grabbing his cock in his hand and stroking it, long thick ropes of cum began to shoot from the end into Dani's face, spurt after spurt dripping from her eyebrows and nose and covering her cheeks and mouth, dripping from her chin onto her chest.

"Leave all of the cum right where it is," Robbie instructed, pressing his cock into her mouth so that she could suck him dry. "You can clean up in your room."

"Yes, Master," she said from around his cock.

"Let's go," he said, pulling her to her feet, picking up her robe.

She reached for the robe, but he held it from her, guiding her by the arm to the hallway to their rooms. Dani felt her knees shake as she thought of being caught like this, naked, her face covered with her brother's cum.

As they approached their parents' door, Dani was surprised and frightened to see that it was wide open. Ellen had not closed it when she had dashed back in after calling to them. Just as they got to the opening, Ellen emerged from her bathroom, her arms above her head toweling her hair. They all three froze, staring at each other, Robbie's eyes locked on his mother's nakedness, her huge tits suddenly sprouting large hard nipples, and her pussy, the lips smooth and shaved, her fat clit sticking out from between them.

Ellen couldn't breath. She thought she was caught in some kind of a nightmare. She was standing naked in front of her children, her arms above her head, posing for them. But her children, something was wrong. Robbie's cock was sticking out in front of him, glistening, huge, and he was holding Dani's robe in his hand. And Dani, she was next to him, naked, her face covered with cum, which she saw was dripping from her upper lip into her wide-open mouth.

Robbie handed Dani her robe and gave her a nudge, snapping her out of the frozen trance she was in. Dani grabbed the robe and dashed into her room, shaking with fear and embarrassment as she shut the door behind her, leaning against it. She felt cum dripping from her eyebrow and she instinctively reached up and wiped it away, automatically licking it from her hand before she realized what she was doing. She groaned as the taste of it made her pussy ooze wetness and she continued wiping the cum from her face into her mouth as she stumbled over to the bed and sat down, wondering what was going to happen next.

After Dani had left, Robbie just stood there, staring at his mother as she remained frozen with shock, staring at his cock. As he reached down and wrapped a hand around it, Ellen came to her senses, lowering her arms and slowly walking over to the door, gently closing it in her son's face.

"What was happening?" Ellen wondered. What she had just seen was so bizarre as to defy her ability to believe it. Hardly aware of what she was doing, Ellen managed to dress for work, even as her mind roiled in turmoil. It was with great trepidation that she finally opened the door again to leave, letting a big sigh of relief escape her lips as she realized she had been dreading finding Robbie still standing there, his incredible cock in his hand.

And that's what bothered her the most, the fact that she couldn't get the image of that beautiful cock out of her mind. She had never had a sexual thought about Robbie, or Dani for that matter, yet here she was confronted with the most blatant evidence of perverted sexuality between her two children. Her mind flashed back to the image of Dani standing with her mouth open in shock, cum dripping from her upper lip into her mouth. But what she most remembered was Dani reflexively swallowing and then licking her lips. Her face had been just covered with cum. And it was very obvious that it had to have been Robbie's.

Stepping out of her room, she couldn't help noticing that Robbie's door was wide open. She couldn't just leave and pretend that nothing had happened. She looked into Robbie's room and saw him sitting at his computer, his back to her.

"Robbie," Ellen managed finally after clearing her throat, "I think we need to have a talk later when I get home from work." (next Chap 2)
