While helping Twilight with an experiment, Rainbow accidentally gained the power to control ponies' minds. But that's not a problem. There's nothing wrong with being hypnotised by her. It's perfectly normal to be Mistress Rainbow's sex slaves.

Twilight, in need of an assistant for a delicate magical experiment, enlists the help of Rainbow Dash. With a little apprehension, true, the pegasus isn't exactly well-known for being fit for a laboratory, but what's the worst that could happen? Rainbow Dash gaining hypnotic powers and turning her friends into her mindwarped sex slaves? ...that's not a bad thing though, right?

Contains: hypnosis, masturbation, triple penetration, chanting, altered personalities, use of hypnotic triggers, some induced animal-like behaviour, induced arousal, no concern whatsoever for consent, harem, lesbian sex, hoof licking, oral sex, sex toys, some minor bondage

A commission for superfun.

On the importance of picking the right partner when experimenting with unidentified magic

"Now I just need to close the magic circuit and..."

"...and?"

"Um." Twilight brought a hoof to her chin, frowning. "I don't get it. It should be working, so why..." She glanced around. "Rainbow!"

"What?" the pegasus asked.

"You're standing in the middle of the circuit!" Twilight waved a wing at the mare. "Oh, I knew I should have waited for Starlight to come back before doing this."

Rainbow looked down to the ground, where the lines of glowing chalk passed right below her body, the light interrupted by her presence. "Oops. Sorry about that." She stepped to the side.

Twilight grunted, staring at her experiment. "Oh, great, now where did the magic go? Oh, Starlight will send me to the moon herself if she finds out I lost it!"

"So, huh, what exactly is this thing about?" Rainbow asked, stepping forward.

Twilight groaned. "Well, we found this thing," she explained, lifting up an ancient-looking necklace decorated with spiral patterns from one end of the circuit. "It has, or at least had, some kind of spell infused into it. We weren't sure of what it did, so I decided to extract the spell itself to study it. Until somepony decided to sit in the middle of the circuit, that is."

"Huh. So did the spell go inside me or something?"

Twilight rolled her eyes. "Rainbow, that's not how..." She paused. "Actually... Do you feel any different?"

"Not really?"

"Hold on, let me get a good look at you." The alicorn walked up to Rainbow and began to inspect her, grabbing her and running her eyes over her body.

"Hey, wait!" Rainbow complained, trying to wriggle away from Twilight's grasp only to be caught in her magic and immobilised by it.

"Just hold still for a minute." Twilight brought Rainbow to be face to face with her. Noticing something, she began to ask, puzzled, "Have your eyes always been like... like... I..."

"Twilight?"

The glow of the alicorn's magic faded away, and Twilight stood there, her gaze empty and her breath calm.

"Are you alright?" Rainbow asked, getting a better look at the mare.

"I'm perfectly fine, Mistress. I eagerly await your command, Mistress," Twilight calmly breathed out.

Rainbow stepped back, smirking. "Ah! Very funny, Twilight, but you should leave the pranks to me and Pinkie."

Twilight stood motionless.

The pegasus coughed. "Twilight?"

"Yes, Mistress?"

Rainbow gave a small, awkward chuckle. "Wow, you're, huh, really pushing with this thing, aren't you?" She took a couple of steps around Twilight, then, carefully, lifted a hoof to prod her on the side. She pushed in, then pulled it back. No reaction. She swallowed. "So, like... How does this Mistress thing work exactly?"

"Once under your control, I will obey any of your commands. I will remain in this state until you choose so. Any order you might give me that involves lasting consequences will still be in effect once I am awakened from this state."

Rainbow swallowed again, as a blush began to spread across her face. "Anything I say?"

"Anything you say, Mistress."

The pegasus bit her lip. "Well... Ah, roll on your back," she tried after a moment of hesitation.

Silently, Twilight lowered herself, then rolled to the side until she was lying face-up on the floor.

Rainbow's breathing quickened, as she awkwardly fidgeted with her hooves. "And you said I can make you do anything?"

"Yes, Mistress."

Frowning in thought, Rainbow paced back and forth. "Twilight?" she called, snapping to a halt. "Teleport a book here. Doesn't matter which one."

Twilight did as instructed, a large volume on alchemy appearing in a flash of her magic.

"Okay. Now light a small, contained fire on the floor."

With a zap of her horn, the alicorn did as she'd been asked.

Rainbow took a deep breath. "Twilight, drop the book into the fire."

Twilight did.

Rainbow barely managed to catch the falling book and put out the fire with a push of her wings. She stood there for a moment, panting, watching Twilight's body on the ground, as the reality of her situation set in. She was hers, completely. Her eyes wandered to Twilight's exposed nethers. She shouldn't, she really shouldn't. But she could always make her forget about it, no?

She stepped forward, and stood in front of Twilight's body. Twilight was her doll. Her plaything. Twilight Sparkle, the mare she'd been attracted to since she'd first met her, the mare who'd only gotten more sexy once she'd grown a pair of wings. Not that Rainbow wasn't somewhat attracted to every mare she met, but Twilight had always held a certain allure. She'd fantasised about having sex with her on more than one occasion, and now there she was, her will completely in her hooves. It was wrong, but how much could it hurt to just watch? Hesitantly, she spoke, "Masturbate for me, Twilight."

Mechanically, Twilight began to massage her marehood with her hoof.

Rainbow felt an odd mix of sensations. Surprise, for one, she had expected the alicorn to use magic. Beyond that, she felt a bit of shame for using her friend like that, but at the same time, some part of her enjoyed the idea. Having Twilight completely at her mercy. There was something that could be improved about it though. "What are you thinking about?"

"Nothing in particular, Mistress," Twilight replied, still rubbing her moist nethers as her breathing quickened slightly.

Made sense. She hadn't instructed her on anything specific. Time to fix that. She had found herself enjoying the control she held over the mare, now to see if there was something more to it inside her. Bringing a hoof to her own set of lower lips, Rainbow began, "I want you to think about me. I want you to think about how I have hypnotised you right now. It makes you so horny to think about that. You love the idea of being under my control."

Twilight's movements grew faster, a blush spreading across her face. "I love being under your control, Mistress."

Rainbow's breath began to quicken, arousal dripping from her sex, as a fire heated up in her chest. It felt so good, she couldn't help herself, she couldn't control her own words. She wanted more, more of it. "You're mine, Twilight. You're my slave. You're my toy. You love being mine, you love knowing that I made you mine. It makes you dripping wet, it makes you impossibly aroused to think about how I control everything you are. You love me, you worship me, you are shuddering with pleasure at the idea of me playing with your mind!"

The alicorn moaned, as juices gushed from her folds. "Oh, yes, yes Mistress, I love being your slave, yes!"

Rainbow bit her lip and came, watching Twilight's body convulse in orgasm. As she calmed down, her breath coming in slow pants, she softly said to the still-masturbating mare, "You can stop now." Lying there for a moment, she thought about what she'd just done. How excitingly wrong it had felt, how she wanted to do it again. Maybe she would, one day. But for the time being, that was enough. Getting up, she said, "wake up, Twilight."

Focus returned to the alicorn's eyes, and she slowly got back to her hooves, glaring at the pegasus. "What the fuck have you done!" she moaned out, a line of drool escaping her mouth.

Rainbow jumped back. She'd forgotten about wiping Twilight's memory, clearly. Whoops.

"Seriously, Rainbow!" Twilight continued. "You accidentally hypnotise me, and the first- Well, second, the first was trying to make me burn a book and I think it says a lot that I'm not ranting about that instead- Anyway the first thing you do is make me masturbate for you? And make me horny when I think about how you've changed me, how you've made me your, your toy, your-Oh fuck!" One of her hooves darted to her nethers, where she began to furiously masturbate again.

Rainbow looked at her. The other commands about being aroused hadn't left her either. She should have felt shame at her actions. She should have felt sorry for her friend. But as she looked at Twilight masturbating in front of her, powerless to resist her own urges, the only thing she could think of was how much she wanted more of it. And, she decided, she would get it, very soon. She just needed to do a couple of tests with her powers first. How fortunate that Twilight was there to help with her experiment then.

Applejack diligently kissed Mistress Rainbow's hooves, like the inferior mare she was. The pegasus had proven time and time again how she was the stronger, faster, and all around better of the two, and it was only natural for her to serve as her slave. She was glad she was granted the privilege of touching Rainbow's perfect body. Next to her sat Twilight, eagerly lapping at Rainbow's pussy.

Rainbow gave a lustful yawn. "Fluttershy, routine three," she commanded.

The yellow pegasus, who had been massaging Rainbow's back only a second before, flew in the middle of the room and began to pose and dance, exposing her dripping nethers to her Mistress.

Rainbow smiled, then turned her gaze to Rarity. The unicorn stood motionless in a corner of the room, her eyes covered by a blindfold, her legs tied together by black straps that also covered her back, her horn glowing as she fucked herself with a dildo in each of her three holes. "Chant number one," Rainbow said.

The dildo occupying Rarity's mouth left it with a pop, and the white mare began to recite, "I am a dumb cow. I live only to be fucked. My only purpose is to be a set of holes for others to enjoy. I exist to obey my Mistress' will. I am a dumb cow..."

The blue pegasus smirked. Sitting on her crystal throne, she surveyed her slaves, all thoughtlessly playing their parts, while one of her hooves stroked Pinkie's back, the earth pony resting in her lap and purring like a cat. "Pinkie, dog," she said after a moment.

Pinkie jumped off from her lap and began to pant, her tongue lolling out of her mouth, looking at Rainbow with large adoring eyes as her sex leaked a puddle of arousal on the floor.

Delighted with herself, Rainbow began to give a series of commands to the mare. "Sit. Roll over. Jump."

Pinkie obeyed her every order without fail.

"Good girl," Rainbow finally said, satisfied, and the pink pony immediately came, loudly moaning. Biting her lip, the pegasus moved to push Twilight's head against her folds, a shiver of pleasure running down her spine. "Girls, scene five. Pinkie, you keep cumming there, okay?"

Her only answer was a yelp of pleasure, as the mare's slowly dying climax was relit and she began to shudder and convulse in never-ending orgasmic release.

Twilight remained in her place, diligently sucking on and pleasuring Rainbow's sex, while Applejack and Fluttershy left their positions and stood at the centre of the room. Rarity, having inserted the third dildo back into her mouth, undid her bindings and moved to rest between them, lying on the ground to take her place as the plaything the two would fuck on. The earth pony and the pegasus then positioned themselves over her, Fluttershy slowly sliding Rarity's horn in her sex while Applejack straddled the unicorn's backside and gripped her purple tail. The two began to grind their nethers back and forth, Applejack matting Rarity's back while Fluttershy soiled the unicorn's face with her juices, and both chanted, in perfect unison, "I am a mindless fucktoy. I live to obey Mistress Rainbow. I love being her mindfucked slavecunt doll. I am a mindless..."

Rainbow's breath grew ragged. Pressing Twilight's eager and worshipful mouth harder against her folds, listening to Applejack and Fluttershy's incessant chant of obedience and to the incoherent moans of Pinkie's unending orgasm, staring at Rarity's blindfolded face as she fucked her throat with the toy grasped in her magic, her heartbeat became faster and faster. They were hers, all hers, her toys, her fuckdolls. With a loud moan, she came, spraying her arousal over the alicorn's face. Tired, she laid back in her throne, catching her breath as the others continued on with their routines. Then, her eyes fell on the clock on the wall. With a small groan, she said, "Everypony, wake up."

Twilight found herself staring at Rainbow's sex. Nonchalantly, she pulled herself back and stood up, as the others did the same and Rarity removed the toys she'd been fucking herself with. Mistress had clearly wanted to play with them. Rainbow's actions were horrible and immoral, and they made all of them dripping wet. No matter how against the idea of the pegasus' control over them they should have been, they had been conditioned to love it, and to love the way they'd been conditioned to love it.

"Well, see you tomorrow, slaves," Rainbow said, leaving the room, as all the other mares shuddered with arousal at her words while beginning to clean themselves and the mess they'd made.
