Giving Brother A Better Girl, A Mind Control Story

----------------------------------

	In a world of heroes and villains and adventures etc there's a great demand of news and journalism. Winston was attending classes at a college to get into this field. Some days he felt like he almost wished he hadn't, since the days with gym class wore him out. It was a dangerous job he was planning to get so being able to run back from falling debris and other such things was important. He still hated the fitness classes though. 
	Walking into his apartment he flopped down on the couch. He grabbed the remote from the side table and searched the channels for something good. Unthinkable Wickedness the Mad Scientist in training came into the room and glanced down at the civilian. “Welcome home bro. Another tough day of exercise I see.” 
	The worn out feline nodded his head. “I'm going to bake us up some cookies. If you want any snacks before they're done just let me know.” She went back out of the room into the kitchen. “My request is that you don't use them for any experiments on me.” “Of course not! I wouldn't do that to you on a day you're so worn out. Not only would that be mean... but it'd get better results if I waited for a day you were rested.” This got a chuckle out of him.
	Winston and Kable (her nickname for when her full title wasn't needed, or she was amongst people that didn't know of her evil status) got along great. She was technically evil but generally she was actually nicer than the average person. 
	Stretching out the inspiring journalist sat up on the couch feeling some energy returning. “Scarlett's coming over later tonight to pick me up for a date. So I won't be sticking around for dinner.” Kable had to pause for a second to not slam the oven door shut in anger hearing her brother's announcement. She had never liked Winston's decision to date that girl but tried not to make a scene over it. 
	“I'll make enough so you can have some leftovers if the date doesn't go well.” Closing the oven door on the cookie tray and setting a timer as she spoke out to her brother. It felt to her that she said that a little too hopefully. Hope that he'd finally have a bad enough date to dump Scarlett. 
	They'd had bad dates before but not enough that they split up. While he put the blame on himself most of the time for that happening his sister could tell that it was the bitch's fault. Thankfully he didn't seem to notice the passive aggressiveness towards his girlfriend in her comment. 

	Hours later Unthinkable Wickedness was at her work desk trying to work on something. Every time she attempted to decide on what to continue on her mind drifted to her brother out on his date. He's gone out with other people in the past but this one bugged her more. She was inconsiderate, mean, and whenever there was an issue she managed to put all the blame on him. Kable got more pissed by the minute thinking about how much that bitch needed an attitude adjustment. 
	“Attitude Adjustment!”
	The inspirational choice of words was enough to get her working on a new machine. Why hadn't she thought of this before? She could fix her brother's problems without a messy breakup. Kable had made behavioral modification devices before so this time she just needed one of a slightly higher dosage. Building it was almost child's play for a mad scientist such as herself. A bigger issue came to mind partway through making it, was the question of how to isolate Scarlett from her brother long enough to use it.
	Thoughts swarmed in her head so much she almost didn't notice the sound of the front door. She walked out of her room leaving the machine to be finished later. “Welcome home Winston. How was it?” Her brother looked over to her in a fake sort of expression, trying to seem ok when obviously he had a crappy night. “It was... we got all the way through dinner.” 
	Awkwardness filled the room to the point where neither of them wanted to speak next. Time lingered as they moved around the room slowly waiting for a response from the other but also trying to escape the situation. Sister trying not to explode in a rage of questions fearing he'd hate her for it, and brother trying not to pour his heart out so he wouldn't look like a wuss.
	Both of them ended up back in their rooms after what seemed like hours. Kable worked into the night on the machine and the plan to get alone with Scarlett to use it. She was glad she had thought up the mind control solution. Because after seeing her brother like that yet again she knew that if she hadn't, she probably would have resorted to more violent solutions. Solutions that would have made her brother unforgivably mad at her.

	Scarlett knocked on the door several days after that disastrous date. Apparently her boyfriend's sister needed help with some sort of college project. As much as that sounded horrible she figured that if she came that his sister would like her some more. Normally Scarlett didn't give a crap about what people thought of her but having a little less hostility from her would be nice. 
	“Hello, come on in. I'm grateful for your assistance.” Kable always came off a little strange.  Today it was the kind of strange that would bring to mind a spider inviting it's prey to it's web. It didn't phase her much since it didn't seem any more dangerous than her other kinds of strange she's seen so far. 
	As Kable closed the door behind her she noticed a strange device on the coffee table before she sat down on the couch. “Well you are my boyfriend's sister. That makes us like, future in-laws.” Hearing that made her twitch uncomfortably but she quickly put back on her kindly face. “Right... anyway my assignment is about hypnosis and we're not allowed to use family members as part of this study, so  I figured if I couldn't use Winston that you'd be the best next thing.”
	It was Scarlett's turn to be visually uncomfortable with what the other person said, and she didn't attempt to hide it. “Hypnosis? I'm not sure about that. I don't want any weird shit going on.” Kable nodded and sat down next to her on the couch.
	“I understand the hesitation. How hypnosis works isn't how most people think. It's all about consent. Using functions of the mind to help someone do stuff they'd do already. You can't make anyone do something they wouldn't normally do. Consent being the central part of hypnosis is why people are able to self-hypnotize.” The information seemed to ease her. “Really? Hypnosis is purely voluntary?” 
	“Oh yes! If you don't want something to happen or be made to do something, hypnosis won't force it upon you. So what do you say?” Scarlett gulped a little still a little nervous but seeing the honesty on her face reassured her enough to nod. “Sure. I'll just say no if it gets too far for me.” 
	There was a shared smile between them as Kable picked up the device and aimed it at her face. Strange visual images poured into the girl's eyes. Being the mad scientist she was Kable couldn't help but start to laugh a little as the device forced her victim past the point of resistance.
	“Everything I said about Hypnosis was true. It's a mental mind trick of consent. Too bad for you that brainwashing and mind control are separate, much more forceful things.”

	Half an hour passed as Unthinkable Wickedness looked at the susceptible to commands Scarlett.  Even with the ability to change her there was this feeling inside that she didn't want this girl to be dating her brother. Was it more than just protective instincts? Full on hatred for the bitch? Maybe. But no, there was a stronger feeling she sensed. Something that she never stopped to think about. 
	Kable's never really had a boyfriend. This was usually explained away with the fact that she was busy with learning or creating or experimenting. Now with time and a reason to think about it she realized most guys didn't interest her anyway. Her brother did though. She loved him. Not just as a sister but as a woman who wanted to be his mate. 
	Drumming her fingers on the device that was keeping Scarlett still she pondered what to do about her newly discovered desire. Simple yet potentially disastrous solutions came to mind, such as giving her a suggestion to break up with her brother. Which would break his heart and make it hard to judge when to make a move before another girl gets him on a rebound. She could ramp up Scar's terrible qualities to the point where he'd be crazy not to dump her ass. The reason she created the mind control device was to avoid him having any more bad dates, so that wasn't a good option. 
	After another ten minutes of not giving her any directions Kable finally decided on a plan of action. “Ok, listen carefully because there's a lot to cover and I don't know how much longer until he gets back from his classes...”

	Winston walked up to his apartment happy since it was a day of much more enjoyable classes. Opening the door he was surprised to see his girlfriend standing in wait on the other side. “Welcome home. It's nice to see you again.” He was even more surprised by the kind greeting. “Nice to see you too Scarlett. What are you doing here? Not that I mind...” Quickly adding the last part not wanting to piss her off and get her out of the good mood. “Just that normally you're not here unannounced and so early.”
	She nodded to him as he moved inside. “I came over to help your sister with something. She said I could stay over and have some cookies while waiting for you to return after we were finished.” He rushed to the kitchen and saw a plate of cookies on the table. “Sis, please tell me you didn't put something weird in the cookies.” Glancing back towards the main room he tried to speak quietly so his girlfriend wouldn't hear him. 
	The mad scientist smiled at him not doing the best at hiding what she did. “There isn't anything in them, well besides normal cookie stuff. I wouldn't experiment on your girlfriend without asking you first.” With that he took a cookie and ate it. Partly to confirm since after all the times she slipped something in without telling him he could tell when it had extra ingredients. Partly because he really wanted one.
	“Well then do you know why she's all... well...” “Nice? Pleasant? Able to say a compliment that isn't backhanded?” Scarlett walked into the kitchen in the middle of the conversation but Winston still nodded his head to the questions.”Well that's because I used a brainwashing device on her.”
	“You just said you wouldn't experiment on her without asking!” Since it was brainwashing he didn't worry about yelling at his sister in front of Scarlett. “It's not experimenting if I know exactly what the outcome will be. That's not enough of an excuse though I get it.” 
	Sighing she sat down trying to find her courage. “I'll even turn her back to normal if you want but I need to say something first. Brother, I love you.” He looked at her for a second and to his girlfriend, then back. “I love you too, we're siblings after al-” “NO! More than that! I mean I want to date you, and get married and have kids and I know that's rushing things a bit but it's a romantic type of love.” 
	If anything proved Scarlett was brainwashed it was her being present for that and not saying a word about it. Pre-mind-controlled Scar was the kind of girl that liked picking a fight enough that she made up reasons. 
	“Wow. That's a lot to take in. I'm really flattered.” He grabbed a cookie, then another, stress eating while the thought rolled around in his mind. “If I say no or something are you just going to brainwash me?”
	She gazed at him with a mixture of hurt and anger. “If I was going to brainwash you into being my boyfriend I'd have done it earlier, or have Scarlett hold you down and do it now. I don't want that, I want to actually be with you.”
	“Well it's nice to hear that.” He looked at his brain washed girlfriend. “Not sure I can give you a real answer without thinking it over a while. Could I have a couple more days with her?” 
	His sister nodded to him and moved to get the device. “You want her back to normal bro?” Winston barely held back an immediate response, managing to say it calmer than it was in his head. “Well you went through the trouble to make her... nicer. Why waste that? We can always turn her back later anyway.”

	It had been nearly two weeks since that afternoon. Unthinkable Wickedness had been waiting while her brother had been going on a test run of dating the nicer version of Scarlett. He hadn't come back to her about a definite answer but it felt if it was this long then that was practically an answer in itself.
	Just as she was thinking of doing something to take her mind off of it he came out from his room. “Hey there sis. I had some questions about the hypno thing you did.” Crap, this was like the opposite of taking her mind off of it. “Brain washing, it wasn't consensual remember? But ya I'll answer whatever.”
	“How far can we push it? Like could we give her new fetishes?” It was hard for her to swallow her jealousy. “It depends how extreme but for the most part it should be as easy as any other commands. What... sort of fetishes did you want?” “I was thinking of making her a voyeur. Getting off on watching others.” “And who were you thinking of her watching?” There was a bit of hopefulness in her voice wanting to be right about where it felt like he was leading.
	“Well, I wanted to beat around the bush more and tease you but I don't have it in me. I was thinking she could watch us.” She leaned over and hugged her brother tight. “I'm so happy to hear that. That means you want to go out with me right?” Winston nodded and hugged back. “Yes, took me a while to admit to myself. I'm not a mad scientist like you so my desires were caged away behind normal social conventions. Now we can be together and really mess with that girl's mind.” 
	Kable smiled and leaned back into her seat. “We don't have to do anything bad to her. It would be easy enough to just send her on her way, don't be vengeful on her just on my account.” “Well if you said that to me a couple days ago I might have agreed... but after I knew you were the one I wanted I spent several days thinking of stuff to do with her.” She smiled at him. “Maybe you're a little more evil than either of us thought.” Winston nodded and soon they were in a several hour conversation about what a couple could do with a brain washed girl.

	Scarlett came over to the sibling's apartment again. Most people might mind their boyfriends getting together with their own sisters. Both of them were so nice though so it didn't bother her, besides Kable had the qualities that attracted him to Scarlett in the first place and more. One day she hoped to have a guy that fit as well together with herself as those two did. 
	None of the guys she tried going out with lasted more than a couple of dates anymore. Her fetishes and desires seemed to scare them off but it was their loss. She was still young and in college so it was fine. That and the siblings allowed her to come over and participate in their love making. 
	When the door was closed behind her she stripped all of her clothes off. Wait, why was she getting naked so fast after getting here? Because she liked getting naked. There wasn't any need to even have that silly question pop into her head. Besides she had a couple to serve, she didn't want to keep them waiting any longer. 
	The three of them went back into one of their bedrooms. Scarlett didn't notice or care who's, she was too busy getting on her knees and rubbing Winston's cock to make sure it was hard and ready. Unfortunately shortly after that all she could do was masturbate and watch the siblings fuck for a while. Usually they liked focusing on each other at the beginning of each session.
	Her tail wagged excitedly as he pulled out of his sister, and then she dove into her crotch face first to lick the cum out. A hand grabbed on her hair and pulled her away from the tasty treat. “Slave, did you forget that you have to ask first if you want to taste my cum?” She whimpered lightly up to her master. “C-can scarl- slave eat your cum out of mistress's pussy?” Relief washed over her when he let go of her hair. “Fine, but you're still getting punished for going for it without permission first.” 
	Slave nodded as she went back to Kable's crotch, getting a rough spanking from Winston as she did. With each smack to the behind she just got wetter and wetter. Even when it was starting to make her sore it just turned her on to the point of practically forgetting her own name.
	It slightly disappointed her that Winst- Master finished spanking her once she swallowed down all the cum. If she had any consciousness of being brainwashed she'd notice how names and thoughts seemed to change and shift when she became horny, or was in the presence of these two. She was blissfully unaware though, just happy that she could indulge with them. 
	In fact, with her new mindset nothing made her happier than when she got fucked up the ass and filled with cum. Or ravaged by mistress's strap-on. Tied up, blindfolded and gagged so she couldn't do anything to stop the two from doing whatever they wanted with her body. Being used as a urinal and drink their pee for them. Generally being a masochistic slut. 

	The two siblings looked over to Scarlett, who had passed out from exhaustion. “So, when do you think we'll let her go?” Kable shrugged a bit and started to redress. “Well I still don't like who she used to be, but I'm getting really used to having a sex slave. If we let her go we'd just need to find another.” She paused in that thought for a second. “Well, I mean we wouldn't have to if you didn't want to bro.” “We could try and find someone that's into this brainwashing junk. I'm sure someone out there has a fetish like that and we could give it to them.”
	They smiled a bit to each other. “Rationalize it however you like, I think you're starting to come over to the dark side. Now let's go to the kitchen and I'll make you some cookies.” He nodded and got on a shirt. “As long as you don't experiment on me with them.” “Oh come on, why would I do that to my own brother? We have a perfectly good genie pig resting on the bed, I'll make her some to test out for when she wakes up.”
