My Sister, The Bitch

byTryAnything©

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.
