Kimberly Keats sat cross-legged on the family sofa, headphones in ears, bobbing her head as she listened to some catchy music. Her hair, jet black with green dye on the curly ends, bounced adorably along with the beat. Her younger brother, Ben, sat down next to her and turned on the TV. For a moment, her head bobbing stopped as her brother's arm brushed against hers. She jerked her arm away, and he looked confused.

"Sorry, I didn't mean to startle you." He said sincerely. After a brief pause and a look of worry, "Hey, are you okay?"

Kim gave her head a small shake, looked her brother in the eyes, and said in perhaps too normal of a voice. "Of course I am, just a little jumpy." She forced a giggle.

That seemed to be enough, he nodded and moved to grab the remote. Their parents had gone all out last Black Friday, and their living room now featured a complete surround sound system and a huge 4k TV. For a moment, a split second, Kim could have sworn she saw spirals as the TV turned on, but it was only the default blue screen. She fought to keep her eyes from crossing at the thought of the mesmerizing spirals, but then jumped as the start-up sound of Ben's game console starting boomed through all the speakers.

"Sorry!" Ben quickly moved to lower the volume.

"It's okay, I'm okay, really!" Kim assured her brother.

She quickly glanced down at his crotch, and immediately looked away. "Don't think about it," she thought to herself. "That's Lexie talking. Not you." Her thoughts then dwelled on her former Sister, her Master, and what she had done to her. How Kim was kidnapped and brainwashed into wanting to serve her brother, that Jake was her brother, and what she needed to do with him.

Her real brother had begun to play a game, a new shooter that had just come out, and Kim couldn't help staring at him as his brown eyes were locked to the screen. Like her, he wore black framed glasses, and his hair was curly on the ends but cut much shorter. He was taller than her by about five inches, and she couldn't help but think about him holding her down, looming over her with his lanky yet strong body, thrusting his giant brotherly cock inside of her.

She had to excuse herself and run to the bathroom. She locked herself in and proceeded to furiously rub herself, thinking about her little brother. She had thought about his cock every night since her first night back home, when he had walked out of the shower, his cock naked and erect. It was in her dreams, her nightmares, and her daydreams. His cock tortured her mind every moment of every day, and it was difficult to think about anything else. Some nights she legitimately considering slinking into his bedroom while he slept, and attempting to suck his cock, hoping he wouldn't wake. She just wanted to taste it, just once.

It wasn't just that it was a nice cock, it was that it was her brother's cock. Her incestuous lust was so strong, no other person, no matter how attractive, could catch her attention. They weren't her little brother. They weren't her family. The only other man she even briefly considered since she got home was her father, but it just wasn't the same.

"Damn you, Lexie." Kim breathed out as she began to reach orgasm. The spirals briefly appeared in the back of her mind, always following her, always haunting her. Lexie often appeared in her dreams, encouraging her incestuous urges with the most beautiful and seductive voice in the world. "You exist to be bred by your brother."

Kim desperately tried not to moan as pleasure flowed throughout her body, her breathing growing heavy and difficult. She imagined her brother cumming deep inside her, and her belly expanding...

"No!" Kim tried to catch her breath. She brought herself up to the sink and splashed cold water on her face, trying to calm down. She stared into her beautiful green eyes. Her face had cleared up entirely since she adopted a new skin care routine, a routine she had researched and attempted to try to attract her brother. She tried to tell herself that wasn't the reason why she did that, but it was. What if she... accidentally let Ben see her naked body, like she saw his cock? Maybe he'd get so turned on his massive cock would be visible under his pants. They'd have to fuck, it was only natural. She took off her top, and examined her large, perfect breasts. Surely he wouldn't resist them...

"No!" Kim yelled again as she shook her head, then without thinking ran to the bathroom door. As she opened the door, she was immediately greeted by Ben, hand up ready to knock.

"Woah, I'm so sorry, I was just worried about you..." He shielded his eyes from his sister's boobs.

This was it, this was the moment she was thinking of. He wouldn't resist. He couldn't resist. She had to do it.

"I'm fine, Ben..." Kim grabbed her brother's hands and took them down. She gazed into his beautiful brown eyes and he met hers, growing very uncomfortable.

"Kim... what are you-"

It was an instinct, a need, an impulse she couldn't stop. She kissed him, right on the lips. She held herself there, her eyes closed, his eyes wide in shock. It lasted for what must have been only a couple seconds. For her it felt like an eternity, but also not enough.

"Kim, what the actual fuck!" Ben broke away from the incestuous act and wiped his mouth off. Kim was on the verge of tears as she realized what she had done, or perhaps the worst part, that it didn't work. "I'm your brother!" He sounded horrified and disgusted.

"Ben, I..." She stammered out but he had already stormed back to the living room, returning to his game.

"Why? Why did I do that?" She felt hopeless. She had probably just ruined her relationship with her little brother forever. All because of impulses left over from Lexie's programming that she just couldn't let go.

She held the tears back, and turned to look at herself in the mirror. "I know what I have to do." She said to her reflection. "I have to fix this."

***

It had been seven months since Kimberly had escaped Lexie and Jake's brainwashing, after Jake had what one might call a change of heart. At least she thought she had escaped. After returning home to her family, it quickly became clear that she woke up from her reverse programming too early, and had suffered every night as a result. She was mostly herself again, but it felt like much of the programming remained. Far too much. Part of her secretly relished it, but a bigger part of her wished she had somehow known back then to let Jake's merciful program finish fixing her.

After she had overpowered the evil siblings, she destroyed all of the equipment they used to brainwash her as well as two other unfortunate girls, but she couldn't bring herself to destroy the computer hard drive that had the brainwashing program. She took it for herself, unsure what to do with it, but now she knew it was the only chance she had of truly being free.

She shook with fear as she dug the hard drive out of the bottom of her underwear drawer. She knew it was incredibly dangerous. Jake had only improved the power of the brainwashing program as time went on. Once she heard him mention how long and difficult it was to truly break Lexie's mind, a mind since revealed to be more sick and twisted than her brother's, but now everything had been tweaked. The spirals were far more powerful, they twisted your sight, your concentration, and your mind almost instantly. Commands hammered your head from all directions, many clear, and many more too quiet to register with your conscious mind. It was cruelly efficient. Seemingly possible to fight, but in Kim's experience, never for long.

She had already modified the program once before, taking Jake's programming meant to bring her and the other slaves back to normal, and adding one more line before using it on him, "You'll never want to fuck your sister again." All she had to do was find that same file, and play it for herself. Let her experience the reprogramming until she was truly normal again.

Would she ever truly be back to normal again? Did Cindy or Susanne truly return to normal? Were they pregnant with their brother's seed, like Kim had dreamed about every day for the last seven months? She had no way to contact them, and no way to know.

She couldn't dwell on these thoughts. She navigated past Jake's tool to create the programming, and to the folders for the already generated videos, and found many, most made by Jake and some by Lexie. Her hands shook at the thought of clicking on the wrong one, of subjecting herself to one of Lexie's "lessons" on accident. Part of her wanted it to happen. Part of her wanted to show her brother the lessons. He always had an interest in optical illusions, surely he'd love to see the beautiful, irresistible spirals... Kim shook her head. More thoughts she couldn't dwell on.

A file was labelled, "kimbreed.mp4" and it didn't take much of an imagination to figure out what that was. She hovered her mouse over it, she smiled. She could almost hear her Sister whispering to her, telling her to click on the video. The truth was, every day she was brainwashed was pure joy. Life had become so much simpler. She desperately wanted it back. To experience the endless pleasure of being Lexie's sister slave.

"Hey... Kim..." Ben walked into the bedroom without knocking.

"Fuck..." She muttered as she desperately tried to close out the files before her little brother could see. Her whole body shook, and she hit the mute key without noticing.

"What was that?" Ben peered through his glasses at my laptop screen.

"Just a project..." Technically she wasn't lying. "Um... listen I don't know what came over me."

"Kim, I just wanted you to know... I love you." Kim's heart fluttered. "I love you as a sister." Her heart sank.

"I love you as a brother..." Is what she wanted to say before she came to her senses.

"That really wasn't meant to be anything..." She lied.

"You trying to shove your tongue-"

"I'm just nervous about something! Please, I didn't mean anything by it!" Kim pleaded.

Ben shook his head. "Anyway, I wanted you to know that I care about you and I hope your okay. I've noticed how anxious you've been since you flunked out. I understand your having a difficult time, and I'm not mad. Just remember you can talk to me about what's bothering you, okay?"

Kim shook her head, trying to be casual but coming off like a lunatic. "Mmhm!" She smiled.

"Okay, if you need me, I'll be in the living room." He turned to leave the room.

"Okay, thank you!" Kim said, cheerily.

She waited several moments after he left, then closed the door and locked it shut. Her breathing grew heavy and her anxiety raised. She needed to find the right file, the one that would return her back to normal. Then she needed to let herself watch the spirals, one last time. Her relationship with her brother wasn't ruined. It will be awkward to remember, but she could go back to a normal life, all she needed was to remove the last of Lexie's twisted programming.

She heard a soft meow, and a keyboard clacking.

"Get the fuck off of there!" Kim yelled as she ran to grab her cat, Lucy, and pried her off the keyboard. After dropping her to the floor, she sighed in relief, she didn't hear a programming video running. She was safe. "You could have done something really bad, you bitch." Kim laughed, nervous, and returned her eyes to the computer screen.

Her gaze met spirals, and they were locked. "No..." she muttered. "No... which video is this?" She moved to sit down in front of the computer, but her eyes couldn't unlock from the spirals. She felt them cross inward. "No..." She muttered again as she reached blindly for the keyboard.

Her keyboard had four hotkeys, small and close together in the top middle. One to play and pause a video, surrounded by two that controlled the volume. The mute key was on the far left. Unable to look away, she fumbled around the keyboard until she found the key she was sure would pause the video and stop the spirals from moving. She pressed the key with desperation. "Please," she breathed out, "stop..."

She gasped as the voice of Lexie pierced her mind. She had pressed the volume up button, not the pause button. "NO!" She screamed.

"You love your brother. You neeeeeed your brother." Lexie's bewitching voice purred. "The swirls are so beautiful... You need to watch the screen." That was only what she could consciously hear, no doubt she was already being barraged by quiet commands only her subconscious to comprehend.

"I'm not listening to you, Lexie, never again!" Kim growled as she tried as hard as she could to divert her eyes from the spirals. She managed to do it, but only for a second before she glanced back and was instantly relocked.

"You want this to happen. You need this to happen." Lexie's voice pierced Kimberly's thoughts. Her thoughts were that of her Master's. Her Sister was her Master.

"No... no I don't want this..." Kim could feel pleasure, the type of pleasure she could only receive through getting mind fucked, begin to slowly pass through her body in waves. She moved her hand back to find the pause button.

"Sit comfortably, relax, listen to my voice." Kim found the pause button, and summoned all of her will to press it as she laid back into her chair, eyes completely crossed inward and unable to process any visual information except for the warping spirals. "You need to hear your sister's voice..."

She could have sworn she had found the pause button, but when she pressed her finger down she only made the volume louder. Her left hand, free from the keyboard, reached down to her pussy. It was wet.

"You love your brother, Kim. You need your brother. You need his seed."

"Yes, Sister." Kim's mouth began to hang open as she rubbed her clit. A drop of drool fell.

"You'd do anything for your brother, anything at all."

"Yes, Sister..." Kim droned out. The drool began to fill her mouth and gargle her voice.

"You'd do anything for me, you give yourself to me, your body and soul..." Lexie's voice almost felt like it was the very pleasure that waved through Kim's body. It was so seductive, so beautiful, so captivating...

Lucy jumped back up on the keyboard, meowing as she hit the pause key, and Kim broke away from the spell.

"No! No Lexie, I'm not your slave anymore!" Kim yelled out through her piling drool.

Lucy purred and pushed her head on Lexie's outstretched arm, the one that had turned up the volume.

"You need to get out of her right now!" Kim picked the cat back up and brought her to the door, letting her out before shutting it again. Her eyes crossed inward as she returned her left hand to her clit, and she let herself fall to the floor.

"Body and soul. I give myself to you, Sister. I give myself to you..." Kim moaned out as the pleasure returned. She knew it wouldn't stop until she reached orgasm, so she let it happen. "Forever and ever, Sister, my body and soul belong to you. I'll never escape you, never." The orgasm came, and Kim stifled her moan as the intense, burning pleasure shot through her, the pleasure of being mindfucked by the spirals.

She brought herself to her feet, and walked back over to the computer. As soon as she sat back down she closed whatever file she had accidentally played so she could resume the search for the file that would allow her freedom. She saw what video had accidentally played, it was called "noescape." Kim laughed. "That's what you think, bitch."

Finally she found a file called, "freedom." It had to be it, every other file name was about slavery, incest, and breeding, maybe followed by some extra letters or numbers. Kim breathed in a deep breath, and let it out slowly. This was it, this would bring her back to normal. She could love her little brother as a big sister truly should. She could stop dreaming about him every night and pursue other romantic relationships, proper ones. All she needed to do was watch the spirals one last time. She double checked that the door was locked, got out her best headphones, and sat down to watch her final lesson. Jake's voice would soon wash over her, and it would be words of freedom, of living a normal life, of having a normal brain.

Kim swore every expletive she knew under her breath when she immediately heard Lexie's voice instead. She reflexively pressed the pause button, but not before Lexie's first words came to her ears. "Don't stop."

"No..." Kim could feel her hand still hovering over the pause button. "No this isn't what I wanted..." She could almost hear Lexie giggling in her head. She wanted so badly to press play, to never stop, to take in every seductive word and let it wash her troubles away. She thought about how good the pleasure was simply from listening to the recordings. Simply giving herself to the spirals made her feel so good, let alone pleasing her brother and Sister.

"Don't stop..." Kim whispered. "Don't... stop... can't... stop..." Kim's eyes crossed inward as her finger hovered over the button. "I want this..." Kim breathed out as her left hand returned to her pussy yet again. Her eyes widened in shock at what she was saying. "No... I don't want this. I need this to end... I need... I need..." Her thoughts went to her brother's cock. How she dreamed about it every day. How desperately she needed it every day. Soon he'd be going off to college himself, and she'd lose any chance she had to have his cock inside of her. Their parents were gone for a week. She had kissed him and shown him her beautiful large breasts. If she was going to have her brother's cock, it was now or never. "I need my brother's cock..." She whispered in desperation as she rubbed her still soaking pussy for her brother. "I need my brother's cock..." She said again. "I need... my Sister... to guide me..."

In a moment of weakness, Kim felt her finger press the button. She regretted it immediately, but only for a split second, before the spirals and audio pierced her mind once again, and she fell into ecstasy as her mind was fucked once more.

"You can never stop listening to my voice, you will never truly be free. You need your brother's cock." Lexie's most prominent voice echoed above thousands of other commands. Kim's eyes crossed completely inward.

"Yes, Sister."

"You will do anything to get your brother's cock."

"Yes, Sister."

"You won't let him escape."

"I won't let him escape." Kim began to drool. Lexie's command referred to Jake, but Kim's broken mind only perceived it to be about her real brother. She couldn't let him escape. She couldn't let him leave her and go to college. Not without her.

"If he tries to escape, you will show him the spirals."

"Yes, Sister I will show him the spirals."

"You need him."

"I need him."

"You love him."

"I love him."

"You're crazy for him."

"I'm so crazy for him..."

"Your brother will be yours forever, and ever and ever and ever..."

"Please Sister, give me my brother. Let him be mine forever and ever and ever and ever..." As the rest of the hour long video continued, Kim wouldn't stop repeating those last two words, even as she took in everything else. She was completely fixated on them. She needed her brother. She was crazy in love with him. She needed to have him, forever and ever.

***

The lesson finished, and Kim knew what she had to do. That night, she took the bathroom mirror, her closet mirror, and her parents large bedroom mirror and carried them all down to the living room, positioning them carefully both to the left and right sides of the room, as well as one behind the sofa. She took out a USB containing a new video she had made herself, and inserted it into the game console, shaking with excitement as she did so. The trap was set.

It was two in the morning. The same time she had first seen her brother's sexy cock. She knew now what needed to be done, and couldn't believe it took her seven months to realize it.
Her brother was awake and jerking off. She could hear him through his bedroom door, and she thought about her mouth around his cock. He'd be so much happier if he simply stopped worrying about their incestuous connections. They'd both be so much happier. This was for the best.

"Ben, please, I need to show you something, it's really important!" She cried through the door.

Ben jumped, "Kim, uh I'll be right there!" He didn't finish. His cum was saved for his big sister and he didn't even know it.

"Please hurry. I'm not okay... meet me in the living room." Before he could ask another question, she left.

***

Ben couldn't see anything in the darkness, all the lights in the living room were turned off, and the light switch was inconveniently on the other side of the room. "Kim, are you here? What's wrong? Are you okay?"

"No, I'm not... But I will be!" Kim giggled.

"Wha-" The 4k TV turned on, the light filled the room as the spirals bounced off of all four of the mirrors. Ben was right in the middle, no matter which way he turned, he saw the spirals in at least some portion of his eyes. In the light of the spirals, he saw Kimberly sitting on the sofa, completely naked, legs open, her pussy on full display. She giggled as her eyes crossed, falling prey to the spirals herself.

"Listen to your sister's voice, Ben." Kim's voice boomed through the surround sound speakers, seeming to circle around him just as the spirals did.

"I can't..." Ben closed his eyes and brought his hands to his head as it began to ache.

"You can't think. Neither of you can think. There is only one thing. One thing both of you can feel. Pleasure." Kim let out a moan as she began to rub her pussy, waiting eagerly for her brother to see it. For now, his eyes reopened and he couldn't stop looking at the most perplexing optical illusion he had even seen. It fascinated him. He couldn't look away, and his cock hardened as pleasure shot through his body in a way he never felt before.

"Brothers exist to serve their sisters." This time it was Lexie's voice. It was the second most beautiful voice Ben had ever heard. The most beautiful voice, was his big sister's.

"No... stop..."

"Brothers need to eat their sister's pussy."

"I..." Ben spun around to turn away from the omnipresent spirals, and his gaze was only able to be taken by his big sister's pussy. He watched her play with it and wiggle her body back and forth, back and forth. He felt his eyes start to cross.

"Sisters need to please their brothers." Kim's voice purred through the speakers.

"Sisters need to please their brothers..." Kim droned back.

"Brothers and sisters belong together." Kim's voice pierced Ben's mind.

"Together?" Ben asked in a daze as he slowly moved closer to his sister.

"Brothers and sisters are meant to fuck each other."

"What... no... I..." Ben kept trying to fight it, but fell to his knees and started crawling towards his sister's pussy, not taking his eyes off of it.

"Your brother's cock will be the best thing you have ever tasted."

"My brother's cock will be the best thing I have ever tasted..." Kim droned. Her tongue began to hang as she thought about the taste of her brother's cock. Drool streamed down it on to her stomach.

"Kim... please... what are you..."

"Your sister's pussy will be the best thing you have ever tasted." Kim's voice echoed in circles around the room, spiraling around his mind and piercing every corner.

"Kim... don't do thi-" He kept slowly crawling to his sister's pussy, unable to avert his eyes.

"Your sister's pussy will be the best thing you have ever tasted." The programming repeated, louder.

"Kim, I'll never..."

"YOUR SISTER'S PUSSY WILL BE THE BEST THING YOU HAVE EVER TASTED." The speakers boomed out the command a third time, so loud Ben yelled out in pain as he tried, and failed, to resist the programming.

Drool fell from his mouth, and he began to speak in a hazy, dreamy voice. "My sister's pussy will be the best thing I have ever-"

As soon as Ben was close enough, Kim grabbed his head and shoved it between her legs. His tongue shot out instantly, tasting her, as his eyes shot first to his sister's beautiful green eyes, then to the spirals reflecting off the mirror behind her. As he tasted the most incredible taste he had ever tasted, his eyes crossed completely inward.

"By eating your sister's pussy, you pledge yourself to her."

Ben murmured something in acknowledgement as his eyes began to swivel. He drooled for his sister's pussy so much it fell in heaps of incestuous juices, and his huge cock was so erect it was about to burst out of his pants.

"You understand now, don't you? Both of you. You need each other. Forever and ever."

"Forever and ever..." Kim moaned out as her brother licked at her in a frenzy. He mumbled in agreement, but didn't stop drinking.

"Brothers belong to their sisters. Sisters belong to their brothers. You love each other. You need each other. All brothers should fuck their sisters, all sisters should fuck their brothers. It's wonderful. It's natural. It's the way it was meant to be."

Kim began to climax, and her whole body shook violently. She began to scream. It was powerful, intense, somehow even stronger than when she had fucked her "Brother" Jake. She quickly realized why. It was stronger because now it was her real brother, her true soulmate.

"Brothers and sisters, by nature, are soulmates. Brothers and sisters love each other. Even if they don't think they do, they always did. Mad, deep, crazy love. Reserved only for their sibling. No other love is stronger than brotherly and sisterly love."

Ben moaned in pleasure as he drank his sister's juices. She shoved his face further in between her legs and felt his tongue go ever deeper inside her.

"Feel each other, love each other. Show your sibling how much you love them. Rub your sister's pussy. Jerk your brother's cock." Kim's voice pierced her own mind, finally enforcing what she truly wanted to hear in all these past painful months. There was no turning back now, there never would be again. She was happily brainwashing herself, and brainwashing her little brother. They would both be happily mindfucked, forever and ever.

Kim finally relinquished Ben's head from her pussy and he immediately crawled over her naked body to sit beside her on the sofa, his drool and her fluids spilling out of his mouth. His eyes began to literally spin in the same direction as the spirals as he unzipped his pants and dropped them down. Kim's eyes snapped back into focus the moment she saw her brother's huge, beautiful cock. It was so much better than Jake's had ever been, and it belonged to her real brother.

"Let it happen. Feel each other. You belong together. You'll be happy together. Soooooo happy. You belong together. You belong together." Kim's voice breathed out seductively, bouncing around the room.

"We belong together." Ben and Kim droned out their mantra in perfect unison as Ben reached down to rub his sister's pussy, and Kim finally got to put her hand around her little brother's huge cock, stroking it in rhythm with the beats of the subconscious programing. It was there, it was always there, subtly preparing Ben for the final, most important pieces of programming. "We belong together. We belong together. We belong together." They droned.

"Sisters and brothers are soul mates." Kim's began to spin again.

"We are soul mates." The incestuous pair droned as their eyes swiveled faster and faster. The mirrors, the audio, the effect was potentially more powerful than even Lexie's virtual reality headset had been. "We are soul mates. We are soul mates."

"Sisters and brothers cum for each other."

"We cum for each other." Both siblings' speech became garbled under a pile of drool. Ben began to shake and breath heavily, but didn't stop. Some of his drool fell onto his cock, lubricating it for his sister's hand. "We cum for each other. We cum for each other. We cum for each other!" Ben yelled out his mantra as cum spurted high into the air, getting all over himself, the couch, and his sister's arm.

"Sisters can't waste a drop of their brother's cum." Kim took this command to heart immediately, her eyes returned to normal as she began to lick and slurp at every last drop of her brother's cum. Seven months. She waited seven long, torturous months for this moment, and she savored every last drop. Frenzied, she even began licking the sofa where some of it had spilled.

"By drinking your brother's cum, you pledge yourself to him."

"I pledge myself to my brother."

"Body and soul." Kim's voice purred.

"Body and soul." Kim droned.

"Belly and womb." Kim's voice moaned.

"Belly and womb." Kim droned.

Ben stirred at these words, only a bit. "Belly and... what?" The most important part of the programming was about to begin.

"Brothers and sisters fuck each other every day. Every brother and sister exists to breed. You can't resist it. You can't fight it. You need to fuck. Let it happen. Siblings need to breed."

Ben jumped, and spat out his spit. "No, no no no this isn't happening, this is a dream!" He looked to his sister, beautiful green eyes spinning in opposite directions, tongue hanging out, drool pooling on her chest as she wobbled. He grabbed her arms and shook her, "Kim, wake up! Stop this!" He was free only for a moment before his eyes were forced back to the spirals. The subconscious programming prepared him for this. He couldn't look away. Not until the lesson was complete. He needed to breed with his sister.

"Brothers and sisters were always meant to breed."

"No..." He barely managed to whisper.

"Brothers need to cum deep inside of their sisters."

"No!" A pained last yell that fell to a monotone before he had closed his mouth.

"Siblings need to fuck. You love your sibling. You need to show your love. Give your sibling a baby."

"I... love my sister..." Ben's eyes crossed. He couldn't look away. The spirals assaulted him from all directions. His last pieces of free will tried to fight the abhorrent programming, but it wouldn't stop. It was so much easier to give in. To breed his sister.

"You will breed your sibling."

"We will breed." The two droned. Jake climbed on top of his dazed and mind fucked sister, her tongue hanging out. He slipped his cock slowly into her soaking pussy, and had difficulty fitting it in. Slowly, he began to pump. "Yes, Sister..." Ben said. "We will breed."

"You will breed your sibling." Repeated again and again, it assaulted both of their minds as much as it could. It overlapped itself, repeating and repeating and repeating, at varying levels of volume from inaudible to all but the subconscious mind to blaring so loud that the neighbors might have heard it. Few other sentences were uttered at this point. "You love your sibling. Brothers and sisters must breed. Don't stop. Breed."

"We will breed. We will breed. We will breed." They started chanting in unison as Ben pumped his unprotected, raw cock harder and harder. "We will breed. We will breed." Pleasure unlike any Ben had ever experienced, stronger than he had ever had before, filled his entire body at the thought of breeding his sister. Of filling her womb with their perfect baby. Kim felt the same, unimaginable pleasure as her real brother was preparing to fuck a real incestuous child into her. The pleasure alone was enough to drive someone insane. It wouldn't stop until Ben came inside of her. It was pure ecstasy, but ecstasy that needed to end. It was just too much.

"We will breed! We will breed! WE WILL BREED! WE WILL BREED! WE WILL BREED!" They started screaming in pure pleasure. Ben struggled to bring another load so soon after his first one. They kept going. He kept pumping his cock faster and faster. The slap of his swinging balls was inaudible over their screaming and the intensity of the brainwashing program.

"Sisters exist to be bred by their brothers. Brothers exist to breed their sisters. Brotherly and sisterly love is true love. Show that love and breed! Breed! Breed!" Every sentence and word of the programming grew louder and louder. "Breed! Breed! You need to! Have a perfect baby!" The siblings were covered in their own drool, their tongues both hanging out, their eyes both spinning in different directions.

"Tell your sibling you love them! Cum for them! Tell them you love them!"

"I LOVE YOU!" They both screamed in unison as their eyes finally stopped swiveling and locked onto each other's gaze. Ben couldn't possibly look away from his sister's beautiful green eyes. He didn't want to. "I love you, sis! I love you so FUCKING MUCH OH MY FUCKING GOD!" He felt it, the orgasm. The load of cum that would hopefully get his sister pregnant.

"I LOVE YOU, BROTHER! I LOVE YOU BROTHER I LOVE YOU I LOVE YOU I LOVE YOU-"

"I LOVE YOU, SISTER! I LOVE YOU SISTER! I... I..." Ben shook like he was having a seizure. He came. His massive cock shot his massive load as far into his sister's pussy as it could. He grabbed her hanging tongue with his mouth and sucked on it. Their eyes didn't break contact. Kim giggled like a maniac.

"Very good. If you ever doubt yourselves, repeat this lesson. You are your sibling's soul mate, forever. This is why brothers and sisters exist. To love. To breed." The video ended.

Ben hugged his sister tightly, kissing and licking at her hanging tongue. Her pussy dripped with his incestuous seed. There was no going back. Not this time. No morning after pill, no reprogramming to be back to normal. Kim had just brainwashed herself, and she couldn't be happier.

"I love you, Kim. I love you so fucking much." Ben gasped out between heavy breathes and sloppy kisses.

"This is what I've wanted, brother... this is what I've wanted for seven months. I've wanted you so fucking badly. Now we'll be together forever..." Kim breathed out returning the kisses. "Take me with you. Breed me as many times as you can. Watch my belly get bigger and bigger with our precious child." As they kissed, dark thoughts clouded Kim's mind. Thoughts that were partly her own, partly left over from Lexie's programming, and partly an unintentional misunderstanding of how she had worded her own brainwashing.

Every brother and every sister existed to love each other, every one of them needed to breed.

"Brother... when our children are old enough, they'll need to love each other like we love each other. We'll need to show them the spirals."

Ben shook his head as his last remaining resistance to the taboo of incest fought one last time. "No... thats..."

"Wonderful! Don't you want them to have the same love that we do?" Kim kissed him again.

"Yes, Sister." Ben mindlessly agreed as his eyes crossed. They will have as many sons and daughters as they could. When they were all at least eighteen, they would get mind fucked just as he had been. They would love each other just like they did. He would watch as his incestuous offspring bred like they were always meant to. He would command them to breed, and their only response would be, "Yes, Daddy."

"Everyone should love their sibling like this, everyone..." They continued to kiss. Ben rubbed his sister's body all over as she returned to stroking his cock. "All our friends. Our mom and dad. Everyone in town. Everyone in the world! They need to know this love."

"Yes, Sister." Ben moaned in continued pleasure, unable to stop thinking about brainwashing his incestuous offspring.

"I'll make a new brainwashing program. Even more powerful. We'll share it with everyone we can, won't we?" Pleasure shot through Kim just thinking about watching her best friend and her brother, brainwashed to breed with each other. Or even better, Ben's girlfriend. She and her brother were twins.

"Yes, Sister. Everyone." Ben moaned out. "Siblings exist to breed. Brotherly love, sisterly love, is the only love worthy of creating children. We'll brainwash every single person on this planet if we have to. We'll show the world the truth!"

"Oh, yes brother... I can't wait... every sister will be pregnant with their brother's child. Every one." Kim had yet another orgasm

After that night she got to work attempting to create a brainwashing program more powerful than ever. It had to be powerful enough to overtake people's will, even if it was just on a phone screen. If she could pull it off right, she could create a viral sensation, the sensation of falling in love with and breeding with your sibling. First, she would need to test it, and her first target was Ben's girlfriend, Charlotte. Kim would have her brother all to herself, and Charlotte will discover pleasure unlike she had ever known, fucking her own twin brother.

Kim knew she made the right choice. She loved being brainwashed. She knew everyone else would love it just as much as she did. She would find a way to do it easily, no matter what it took. Even if it was something as simple as a writing and sharing a perverted story, if she could find a way to brainwash her readers into obediently breeding their siblings, she would.

She smiled as she imagined the readers of her hypothetically hypnotizing storyline being brainwashed along with her. They would have been getting brainwashed without even knowing it, shocked by the perverted turns the story had taken, but unable to stop. They wouldn't want to stop. She happily muttered mantras for the readers in her head, and rubbed her pussy as she did so.

"Brothers and sisters, by nature, are soulmates. Brothers and sisters love each other. Even if they don't think they do, they always did. Mad, deep, crazy love. Reserved only for their sibling. No other love is stronger than brotherly and sisterly love."

"You love your sibling. You will fuck your sibling. You will show your sibling this story and brainwash them just as you've been brainwashed. You will always keep reading. You will always come back. You will fuck your sibling. Sisters and brothers need to fuck. Brothers and sisters were meant to breed. You have to pleasure yourself as your read this. Thinking about your sibling. Thinking about breeding them. You know you want to. You know you have to. It's all you can think about. Repeat this paragraph until you've cum for your sibling, think about breeding them as you cum. You are such a good reader. You love being brainwashed. You'll keep reading. You'll take in the programming just like the characters do. You will fuck your sibling. You need to breed your sibling. Your sister, or your brother, you can't stop thinking about them. You know which one you've always wanted. Breed them for me. Show them this story. Breed them. Repeat this paragraph until you're mindless and obedient. Docile and happy. Don't stop until you cum for me. You will breed your sibling."

Kim giggled, what a silly thought. Spirals would definitely be better.
