As Denise waited the next day for her brother to return home, she became hornier by the minute. Every second felt like an hour, and every minute was killing her. At the time where Adam was usually supposed to be home, her pussy had soaked her panties to the point where she took them off, and could actually see them dripping on the floor.
She refused to masturbate, even though ever fibre in her body screamed to be relieved.

After waiting for an hour since Adam was due to be home, Denise grabbed her phone and called him. He picked up after a few rings, where Denise was surprised to hear Amanda on the other end. “Hello Denise, what do you want?” she asked.
Denise felt irritated. Not only that Adam was with Amanda, but that he wouldn’t even answer his phone.

“Is Adam around? I need to ask him about something,” she asked, trying to sound normal. She could hear Amanda say some quiet words on the other end, and the low voice of Adam could be heard as an answer.
“No, he says he does not want to talk right now. He says you can talk tomorrow when he gets home.”

Upon hearing this, Denise felt frustration, anger, fear and surprise, all at the same time. She could not wait that long. Not only because she was way too horny, or that she despised the idea of Adam spending the night with Amanda, but also because her ovulation might be over by them, which would ruin a lot of the fun in her plan.
“Tell him that I have something I need to talk to him about when he has the time. I have a video that I need to upload, and I was hoping he could help me with it. But if he is too busy, then I guess I will have to figure it out on my own,” she told Amanda, hoping Adam would catch the hint, and then hung up.

20 minutes later, she heard the front door slam. “DENISE!” Adam’s voice left no doubt that he was seriously pissed off. Denise heard him rushing up the stairs, and then her door practically flew off its hinges.
Adam walked over to her in 2 large steps. “What the fuck is your problem? What the hell is wrong with you?!” he yelled. “I was finally spending a few happy hours with my girlfriend, and then you have to ruin it again, just because you’re jealous as fuck!”

Denise brushed some hair behind her ear. “I don’t know what you are talking about. I just wanted to ask for your help to upload this,” she said, and pointed at her screen. Adam looked closer, and he frowned. “You wanted to upload a video of yourself shopping with Amelia?” he asked her.
She nodded, as she gave him a devious little smile. “What did you think I meant?” she asked him.

Adam turned around, and headed out the door. “Where are you going?” she asked loudly. “I am taking a cold swim to keep me from strangling my sister!” he yelled out from downstairs.

After a few minutes, she heard a splash. She walked over to her window, and spotted Adam in the pool, as he began swimming laps from one end to the other very quickly.
She had put on a new pair of panties before Adam came home, but as she observed the clear outlines of Adam’s muscles, she began soaking those as well.

She stripped naked, while keeping a close eye on Adam, and quickly put on a sexy red bikini instead. She then walked down to the pool, where she sat down in one of the pool chairs. Adam seemed to be intent on ignoring her, and kept swimming without even giving her a single look.
Wanting to at least get some amusement out of the situation, Denise decided to test how long Adam could ignore her.

She slowly began running her hands all over herself. Her nipples became hard as diamonds, and were clearly outlined against the tight fabric. She pulled the fabric to the side, exposing her breasts, and began running her fingers all over herself. She thrust a hand down her thong, and slowly guided a finger inside her soaking tunnel.
She let out a moan, which made Adam turn his head towards her for a moment, before continuing with his laps.

Denise had felt an orgasm nearing after only a few seconds. Determined that Adam was going to be the one to get her off, she pulled out her finger again. She looked around. Their yard was surrounded by a high wall, and she knew there was nobody who could see them, so she decided to tease Adam a bit more.

She quickly pulled her bikini top over her head. She then undid the strings at the side of her bottom, and let it drop to the ground.
Completely naked, she dove into the pool, where Adam was still refusing to acknowledge her.

She joined Adam for a few laps, taking note in the way he refused to look at her.

After a few minutes, she ‘accidently’ bumped into him, so that her breasts were pressed up against his chest. “Oh, sorry,” she giggled. Adam didn’t seem to react. A few moments later, she bumped into him again, and this time he acknowledged her.
“Stop that!” he snapped.

“Stop what? I am just taking a swim, and I got water in my eye. I can’t see where I am going,” she argued, with the most innocent voice she could procure. Adam grabbed her by the shoulders. “Then allow me to show you out of the way!” he told her, and threw her to the side.
Denise smashed into the side of the pool, her head crashing hard into the tiles. She then floated motionless on the water. Adam rushed over to her, clearly frightened. “Denise? DENISE?!”

She didn’t respond. Adam grabbed her naked limp body, and carried her out of the pool. He put her carefully down on dry land. “Denise. Come on, say something!” he pleaded. No response. He placed his hands on her chest, right between her wet beasts, and began to push down in quick thrusts.
After a few thrusts, he leaned down and pressed her lips against hers, as he began blowing air into her lungs. As he did so, Denise suddenly wrapped her arms around his neck, and pushed her tongue inside his mouth.

Adam pulled away quickly, as she giggled. “My hero,” she said with a wide smile. Adam seemed slightly in shock. “It was all an act wasn’t it? You were never hurt by that!” he said.
Denise got up and laughed. “Maybe. In any rate it was your own fault for tossing me in the first place,” he said.

He turned around, picked up his things, and headed back towards the house. “Hey, why are you leaving? It’s boring to be out here all alone!” she yelled, as she pouted slightly. Adam didn’t pay her any attention
She became slightly angered. Climbing out of the pool, she put her bikini back on, and walked inside the house, where she found Adam in the kitchen, pouring himself a glass of water.

“I’ll take one, I am thirsty as hell,” she said cheerfully. Adam put down his glass on the table with such force that it splintered, flooding the table and floor with water.
“Why can’t you just leave me alone Denise?” he snapped at her.

Denise took a step back. “Whoa. A bit irritated today aren’t we?” she asked him. “Really? I wonder why…..” he said, as he threw the remains of the glass in the trash can.

Denise noticed that he had gotten a small cut on his hand, which was now bleeding quite a bit. “Look Adam, I know that you might not like me very much right now,” she started, but before she was able to say anything more, Adam walked over to her and grabbed her throat with his right hand. She could feel the incredible power in his finger as he began squeezing.

“Might not like you very much? I can’t think of any bigger understatement in the world right now. I am watching my life go to hell, because my own flesh and blood is jealous. My sister, whom I helped and loved all my life, is trying to ruin my life, and the life of my girlfriend. Why? Because she doesn’t like my girlfriend, even though she is one of the nicest people on the planet, and because I dared to claim that she herself was not perfect in every way. I wonder how that would anger anyone,” he said slowly.

As he kept squeezing, Denise began struggling to breathe.

He seemed to notice, and released his hold on her throat. He then walked closer to her, as she started backing away. She hit a wall, and found herself cornered. Adam placed a hand on both sides of her shoulders, and lowered his face towards hers, until their noses were only a couple of inches away from each other.

“Denise, I will only say this one time, so listen closely. I am done with your fucking stunts. If not because it would put me in jail, I would beat the shit out of you right now. You act as if this is a game. What you don’t realise, is that people can only be controlled for so long. What are you going to do when you suddenly lose control?” he asked her.

Denise’s heart was pounding in her chest. She was terrified of Adam’s apparent rage, and knew she was in real danger of getting hurt.
Oddly enough, she also felt herself getting excited at her brother’s display of power over her.
Adam backed away from her, turned around, and then began walking away.

Denise swallowed a load of saliva. “I will make you a deal,” she said, slightly surprised at how calm her voice sounded. Adam turned around, his eyes filled with disdain.

“I will let you alone after today. I won’t show anybody the videos I made, and I will delete those that I took of you and Amanda. I also promise that I will stop being so harsh towards Amanda when she visits,” she told him.

Adam crossed his arms. “And what is the price for this sudden kindness?” he asked. Denise caught his gaze. “You fuck me one last time. I want to feel your dick buried inside of my pussy again. And this time, you are going to make me believe that you enjoy it.” He shook his head, and turned around. “I have no interest in having sex with you again Denise,” he said.

Before he was able to take a step more, Denise stopped him. “You know, these marks you left on my neck would be a pretty viable reason to call the police for domestic violence,” she said.
He turned around, and now he was smiling.
“There. That is the real you: The one who tries to control others when things aren’t going your way. Amanda tried to make me see the real you for such a long time, and I kept arguing that there was something good inside of you. That all of your attitude was just a sort of outer coating, hiding a nice and kind person inside,” he said.

A single tear ran down his chin. “I never knew my own sister. I was blind all my life, and now I am paying for it.”

They stood still, looking each other in the eyes for a while.

“If I do this, I want your word Denise: I want your word that you are going to delete the video of Amanda. You are going to delete the videos of us having sex, and you better make sure your friends never mention it. Also, you never try to blackmail me again,” Adam slowly said.

Denise threw her hair back behind her shoulder. “You have yourself a deal. I won’t delete the videos of us having sex though, but I promise that I will be the only one watching them. As I said; I made them for my own pleasure. And I want a last one of our session today. As a consolation, I will start treating Amanda better,” she said.

Adam looked at her. “There is also another thing: If you really end up getting pregnant…..” he said, pointing a finger towards her stomach. “You will not tell anyone that I am the father. Ever! You will never ask me for anything. I won’t help you raise it, I won’t love it, and I might choke it, if I get left alone with it. It will be your own headache.”

Denise shrugged. “I didn’t plan on telling the entire world if my own brother knocked me up,” she said. Adam shook his head. “I don’t understand how somebody with that much common sense, can end up thinking up a plan like this one. I really think you should get some professional help Denise. I am saying this for your own sake, as well as other people.”
Denise just shook her head. “I can handle my own problems little brother.”

Adam took a few steps towards her again, and grabbed her throat again, although not choking her this time. “I will make you a promise: If you break your word, then I will break your neck before you ever have a chance to react,” he said.
He let her go again. Denise rubbed her throat, which was still slightly sore from the first choking. “That won’t happen.”

Adam sighed. “Alright, tell how you want this to go down.”

Denise pointed towards the pool. “We are going to lie down next to the pool, and you are going to fuck my brains out. And like I said: Part of the deal is that you have to try your best to make me believe that you want this. Convince me that you desire me.”
She suddenly got a devious smile. “And do your best to knock me up.”

Adam frowned again, studying her face for a long time. “I don’t get it Denise. What is it you are trying to gain from this?” he asked her. She just shook her head slowly, making her long hair whirl around. “You wouldn’t understand even if I told you,” she said.
He sighed. “Well, if that is what you really want, then I guess I better try to put as much of my DNA inside of you as possible. That way, the child will at least have a slight chance of not becoming insane like its mother.”

Denise laughed at his words. “I don’t care what your reasons are, as long as your baby is kicking inside my belly within the hour. Now, go get a blanket and some pillows, I will go fetch the camera,” she said. They met up outside a few minutes later.

Denise set up the camera and then looked up at Adam. “Alright, make me believe that you want to fuck me,” she told him, and started the camera. She walked over to him, where he pulled her towards him, and began kissing her.

He began caressing her backside, as he pushed his tongue between her lips. As their tongues swirled around, he lowered his hands, and grabbed her ass. He squeezed her tightly. Denise was pleasantly surprised at well he was playing the role.
Adam’s hands crept back up her backside, and he began slowly untying her top. Denise felt her heart pounding hard when the strings became loose. As her breasts sprung free, he leaned down and began licking and sucking her nipples. His tongue was teasing her, as it circled her nipple. She began moaning loudly.

“Shhhh. Keep it down! I don’t want the neighbours coming out to investigate the noise,” he said quietly. His hands began to run down her sides, until they ended up resting at her hips. He undid the knots holding her bikini bottom together, and pulled it slowly away from her body. He then threw it in the pool, where it floated calmly on the surface of the water.

He pushed her gently down onto the blanket, where he made her lie on her back. “Spread your legs,” he ordered her. Denise did as she was told, and could smell her own arousal immediately. Adam got onto his knees, and then buried his head between her thighs. He began eating her out. Denise had never felt so aroused in her life. She tried to avoid yelling out in pleasure, as Adam’s trained tongue swept across her wet pussy lips. “Fuck. This is amazing!” she shrieked.

Denise felt like heaven. Nothing mattered, except the wonderful feeling of Adam’s tongue sweeping across her pussy. She would not have allowed him to stop. Not for anything in the world! She suddenly began shaking and contracting, as Adam pushed her into her climax.

She was sweating and panting when her pleasure finally subsided. Adam stood up, and pulled down his swimming trunks.

Denise was surprised to see that his cock was already completely hard. “I think it is time to put a baby inside that tight little pussy. That is what you want so badly isn’t it? To feel my cum filling you up, impregnating you with my offspring?” he asked, as he dropped to his knees between her thighs.
Denise was breathing rapidly. Her pussy was screaming for Adam’s cock. “Yes, that is what I want. Please, give it to me!” she said.

When he didn’t put it in, she became desperate. “Put it in me!” she said. He just laughed at her. “Beg me!” Denise was on the edge of losing her mind. “Please Adam. Put your cock inside of me. Tear my little pussy up with your fucking huge cock, and breed me like the little whore I am!” she pleaded.

Adam smiled, and thrust his cock forward, burying himself inside her in one single move. At the surprise of this sudden impalement, Denise grabbed a pillow and screamed into it. “Fuck. FUUUCK! It is splitting me wide open!” she exclaimed through the pillow.

Adam fucked her like a beast. He worked his cock like a piston, slamming it mercilessly inside her willing pussy at an incredible rate.
Throwing the pillow to the side, Denise began panting harder. “Fuck Adam. I love your cock!”

After a while, Adam began to slow down a bit. “I can feel my stomach tingling. You know what that means don’t you?” he panted. Denise wrapped her legs tightly around his hips, knowing fully well what it meant. “It means that your pussy is about to be flooded in fresh cum. There is a little baby on the way!” he grunted.

“Yes! Oh god yes! I want your baby inside of me Adam. I need you to breed me. I want my belly swelling with my own niece or nephew!” she panted heavily. Adam began increasing his pace again.

“Here it comes. You are about to become a mommy, you fucking crazy bitch!” he groaned, as he began shooting his cum inside of her. Denise began thrashing and bucking underneath him, as she was overpowered by the strongest orgasm in her life.

“OH GOD! DO IT! Knock me up! Put a little baby inside of me!” she exclaimed loudly, no longer giving a dam if anybody heard them, as she pulled him further inside of her with her strong legs. Adam kept shooting his cum inside of her for another 10 or 20 seconds, and then pulled out.

He turned off the camera, and began putting his trunks back on. Denise raised herself up on her elbows. “I must say I am impressed Adam. You really made me believe it. What is your secret?” she asked him.
He closed his eyes. “I imagined Amanda instead of you. This is how I usually do things with her. Minus the pregnancy part of course, but I just imagined how much I would like to have children with her, so it wasn’t all too hard,” he said quietly.

Denise knew that she should feel angry for Adam thinking about another during the whole thing, but she couldn’t. It was not fair of her, and she had already stretched her luck long enough. “You really love her huh?” she asked quietly. He didn’t answer.

She kept lying on the blanket for about 15 minutes, knowing that Adam’s cum was probably fertilising one of her eggs already.

Afterwards, she got up, grabbed the camera, and walked into the house, without bothering to get dressed. Adam followed her to her room. She fired up her laptop, and found the video of Amanda’s confession. She made sure that Adam watched her delete them, and empty the recycle bin.

She then handed him her phone, and allowed him to delete the files in there as well. Finally, she retrieved the USB drive, which held the last copy, and told Adam he could do what he wanted with it. Adam looked at the drive in his hand. “This is the last one?” he asked.

Denise nodded. “I promise. I will have a talk with Amelia and Carmen tomorrow, and let them know to keep their mouths shut about what happened. I will not bother you anymore, don’t worry,” she said.

Adam put the drive in his pocket. “You better make sure the videos of our….. physical interactions, remains for your eyes only,” he said. She nodded again. “You can trust that it will be so. If not, you can snap my neck.”
“And the promise you made about Amanda?” he asked.

Denise shuddered. “I promise that I will do my best to be nice towards her. That is the best thing I can give you,” she said. Adam seemed content. He made motion to leave, when she grabbed his hand.
“One last thing,” she said. She looked him deeply into his eyes. “Did you truly feel something for me as we had sex right now? Even for a second?”

Adam looked out of the window. “I felt you being sincere about wanting my child. I can’t say I know why, and it doesn’t change the way I feel about it. But it still made me feel proud in some weird way. You wanted something from me, which you never wanted from anyone else.” Denise began to feel a happy, but then noticed that Adam’s eyes were full of tears. “But none of it changes the fact that you are lying, manipulating, power-hungry bitch. I would wish…..that this never had happened,” he said, and left the room.

3 months later, Denise was again studying herself in the mirror. She had kept her word, and not tried to blackmail Adam again since their last encounter, and there had been a distance between them ever since.
Denise had managed to convince Amelia and Carmen to keep their knowledge to themselves. Carmen had taken a pregnancy test, and it turned out Adam had not managed to impregnate her.

He mostly used his time with Amanda away from the house, but Denise had tried her best to be friendly to her, the few times she had been there. It had been painfully obvious that Amanda was not accepting her behaviour as honest, which Denise could not blame her. Even though she had been fully aware that Adam would be not be able to forgive her actions, Denise found herself missing her brother.

As she looked in the mirror though, a little bulge in her belly was a clear proof of how close they had once been.
She began masturbating. One hand was working her pussy, while the other was running over the lump containing Adam’s child.

“You really are inside of me aren’t you?” she asked quietly. “I can feel you in there. You are kicking me, fighting me already. It won’t help you. Your daddy tried to fight me, and he lost. That is why you are in there right now. In a few months you are going to stretch my pussy to its limits, just like your daddy did,” she said.

She began shaking with an orgasm, and collapsed on the bed. “He even claimed that he didn’t want me. But you and I know better, don’t we?” Denise mumbled to herself, before falling asleep with one hand on her stomach, and a little smile on her face.
