A nimbus of magic coated the key and spun it, locking the door shut behind Rainbow Dash. Twilight had begun to be more careful with that after Applejack had almost caught her. Though she wouldn't have been too bothered if the orange mare found out, would she? In fact, wasn't she hoping it would happen? Oh, she would just have to put Applejack under her spell if that did happen. And then, well... She was a strong-willed mare, but would she resist the temptation of doing to Applejack what she was already doing to Rainbow? She was a rather good-looking mare after all. Strong, well built... And she would totally have some rope available, Twilight had been wanting to try out something like-
The purple princess shook her head, forcing herself outside of her own fantasies. There would be a time for those, but now wasn't it. Now was the time to focus on the things in front of her. Specifically, the thoughtless, mesmerised pegasus standing in front of the door, her eyes glazed over and following Twilight's every movement.
It never got old. No matter how many times she saw it, it always sent that same shiver down her spine. It was always so good. The sight of Rainbow Dash, her friend, member of the Wonderbolts, standing there, motionless as she waited for her command. Ready to serve. Ready to please. Twilight's breathing grew a little rougher, and she had to stop her hoof from sliding down her body, her tail raising by itself just a bit.
She regained her composure and walked up to the pegasus, lifting her chin with a wing and staring at her unfocused eyes. Her orders had worked perfectly. "Come to my room tomorrow at sunset, act normal and if anyone asks say you're going there to ask me to lend you a book. Once you have entered my room you will enter your trance," she'd instructed Rainbow at the end of their session the day before. She wondered how much she could use that to play around. She'd seen what she could do to Rainbow, if it all worked the same with lingering commands, then...
The vivid image of Rainbow, in the middle of a Wonderbolts show, suddenly having an orgasm as she was flying through the air flashed through her mind, incredibly alluring despite the knowledge that it wouldn't be worth it. Having her masturbate in the locker room afterwards, though...
Twilight shook her head. It wasn't the time to think about what she could do in the future, she reminded herself once more, as the feathers at the tip of her wing slid inside the pegasus' mouth and she instinctively began to suck on them. That never got old either. She removed her wing from Rainbow's mouth, releasing her head, and wiped her feathers on the blue mare's cheek.
"So who are you, and why are you here?" she asked to her pegasus friend. She knew what the answer would be, of course, but it just felt so good to hear it.
"I am your slave, Mistress Twilight, your mind-wiped sexual plaything. I am here to please you and obey your every command. My mind and my body are yours to use however you wish." Rainbow's tone was flat, almost mechanical.
Twilight closed her eyes for a moment and hummed, as a shiver of arousal ran through her body. "That's right, pet, that's right." She gently pushed Rainbow forward with a wing, and walked up to her behind. "That's right. You're mine." Her tone grew huskier, more breathy. "All mine. Say it for me, pet."
"I am yours," Rainbow droned in response, "all yours."
"That's right." Twilight's horn glowed, and Rainbow's tail was lifted up in a cloud of magic. "You're my slut, my pretty little mind-fucked doll." A red ribbon, once used to hold a book closed, flew up towards Twilight at a gesture of her horn. "Say you are, slut." The ribbon wound around Rainbow's body.
"I'm your slut, your mind-fucked doll," Rainbow monotonously said.
The ribbon was tied around Rainbow's tail with a bow, holding it in place. "You are. And who made you that way?"
"You did, Mistress."
Twilight hummed in satisfaction, admiring her work with the ribbon and the way it left Rainbow completely exposed. She took a deep breath, taking time to appreciate the way she could smell the pegasus' arousal. "Are you horny, slave?" she asked.
"Yes Mistress."
"Oh? And why is that?" A devious smile formed on Twilight's lips.
"You made it like that, Mistress. You ordered me to become aroused whenever I'm with you in this state. You know I can't disobey you, Mistress."
"And why aren't you showing it more clearly?" Twilight almost had to stop herself from giggling.
"You forbade me to."
Twilight only barely managed not to laugh. It wasn't the first time she'd done something like that, but that didn't make it any less entertaining. "You're allowed to show your arousal," she said, holding a hoof over Rainbow's cutie mark.
The pegasus' breathing grew faster and deeper, a rush of blood colouring her cheeks as a small line of drool started to flow out from her panting mouth. She looked at the ground, curving her back. Her legs began to twitch in excitement and her wings jerkily opened up, lifting themselves from her body.
Twilight massaged Rainbow's ass, smiling. "You're allowed to beg me, slave."
"Please-" the voice came hoarse out of Rainbow's throat, "Please Mistress. Use me, Mistress, please! I-I-" a loud moan forced itself out of the pegasus' mouth as Twilight moved her hoof closer to the inside of her thighs "-I can't take it any more, please, I need you, fuck me, ple-"
"Stop."
Rainbow went silent, the only sound in the room that of her ragged breathing.
"Stop showing your arousal."
Rainbow's breathing went back to normal, and her slightly arched back straightened, her eyes now pointed straight ahead.
Twilight chuckled, and ducked forward just a moment, giving a lick to Rainbow's still dripping pussy. "You're very nice when you're like this, you know?"
"Like a proper toy should be. Unmoving, waiting for your command. I am your doll, Mistress."
Twilight looked back at Rainbow's face. She lifted a hoof and pushed the pegasus' head to the side, then removed it and watched her slowly go back to her original position. She smiled. The conditioning was working flawlessly. "What are you?" she asked again.
"Your hypnotised sex toy, your doll for you to play with, Mistress."
Perfect. A wooden ruler floated up, enveloped in the glow of Twilight's magic, and levitated just behind Rainbow's ass. Then it struck her. One, two, three, four, five times, then it went back on the table, leaving five red lines on the pegasus' behind, arranged in the shape of a stylised star. "You're allowed to feel that, and react," Twilight said, walking towards her bed.
A loud scream of mingled pleasure and pain came from Rainbow's lips.
Twilight reached her bed and kneeled down, then removed a section of the floor beneath it with her magic and took out an object with a white piece of cloth wrapped around. She turned back towards Rainbow and beckoned her forward with a gesture of her wing, then removed the cloth to reveal a glass dildo floating in her magic.
At a gesture of the alicorn's wing, Rainbow dash walked forward, and as Twilight gently pressed down on her head she lowered it and lifted up her haunches, spreading her legs to present herself. It was all so natural to her. Her Mistress had ordered her to act that way, and all she had to do was obey those commands. It felt good to obey her orders. It felt so fulfilling, like it was the only purpose of her life. She didn't need a reason to obey, the act itself of obeying Twilight was her reward.
"You're allowed to react." Twilight walked up behind her, and began to teasingly rub the tip of her dildo up and down Rainbow's dripping slit. "Do you like that, you slut?" she asked.
Rainbow moaned. "Yes, Mistress!" she cried out. She was Twilight's slut, she got horny when her Mistress took control of her mind and body, she loved being deprived of her freedom and made to obey her every whim. She loved to be used, to be Twilight's eager slave. There was nothing else in the world that mattered more than Twilight to her, nothing better than doing what she said.
Twilight moaned as one of her hooves made its way between her legs and she began to slowly rub herself. "Do you want more?" she asked to her slave, as the dildo held in her magic kept teasing at the pegasus' pussy.
"Yes Mistress!" Rainbow moaned again. "Please, Mistress," she added in a softer, panting tone.
The dildo slowed down to a halt. "What if I don't want to give you more?" The dildo floated away from Rainbow's nethers, and Twilight briefly licked the tip before talking again. "Do you want to feel good, slave?"
"Yes," Rainbow practically begged, her hips twitching as she just barely held off from trying to push them back on the dildo.
Twilight positioned the toy at just a hair's distance from Rainbow's entrance, making sure the blue mare knew it was there, just barely out of reach. "You can push back if you want. There'll be no consequences. But..."
Rainbow's breathing quickened, but she waited for Twilight to finish.
Twilight smirked. "But that's not what I want you to do."
Rainbow Dash moaned, but remained still.
"You want it so bad, don't you?" Twilight moved her face closer to the pegasus' sex, her breath hot on her exposed skin. "You want me to keep going, right? You want me to put this toy inside of you, and push, and thrust, and fuck your pussy, and keep fucking it until your legs give out and you start to scream as you cum your useless little brains out. Isn't that what you want, fucktoy?"
Rainbow's moan was almost growl-like, coming from somewhere in the back of her throat. "Yes," she slurred out, drool dripping down her chin at the images her Mistress was putting in her mind.
"So come on, Slave. Do it." Twilight watched Rainbow's body as it shook and trembled, the pegasus' induced lust and desire battling her absolute devotion to her Owner's will.
Rainbow's body was damp and covered in sweat, her breathing ragged. Her eyes half lidded, her legs shaking, drool dripping down her neck and her own arousal flowing down her thighs. She was barely aware of the world around her at that point, Twilight's breath on her sex and the commands inside her building up her arousal to the boiling point, her body ready to explode in climax and her mind filled with nothing but the thought of the pleasure she could so easily attain, just by pushing back a little. But she didn't move. She was a good slave, and she didn't want to disappoint her Mistress.
Somewhere inside her, the part of Twilight that still objected to her actions was snuffed out, at least for the rest of the night, completely overwhelmed by the one that loved the power she held over the pegasus. It wasn't just the sex, it wasn't just seeing her do what she told her. It was knowing that she didn't have a choice. She was hers, completely hers, and everything she requested Rainbow would obey, without the slightest possibility of the contrary. She owned her, her body, her mind, it was all her property, and she loved it.
Rainbow Dash kept panting, still dripping from both pairs of lips.
Twilight began to maniacally cackle internally. "If I told you that our session is over, and that you aren't allowed to cum until the next one, what would you do?"
"I would leave your house, and refrain from masturbating until you told me I was allowed to cum again," Rainbow managed between moans.
"But you want to cum, right?" Twilight asked, walking forward at Rainbow's side.
Rainbow nodded, her mouth still half opened.
"Then why don't you just push back, and let go?" Twilight passed Rainbow and turned around, staring in her eyes.
Rainbow tried to look up at her Mistress, her eyes still unfocused. "Because..." She moaned. "Because what Mistress wants is..." Another moan. "What Mistress wants is mo-more important than what I wa-a-ah... I-I..."
Twilight smiled. "Good pet," she whispered before cutting off the pegasus with a kiss. Her magic pushed the dildo forward and deep inside Rainbow's pussy.
The pegasus screamed inside Twilight's mouth. Her eyes rolled back, her wings shot out, and her pussy twitched around the toy, sending spurts of her arousal flying behind her. Her mind went blank for a few seconds, and electric rush of pleasure coursing through her whole body, then the peak of her orgasm passed and she melted into the alicorn's kiss, basking in the soft afterglow of her climax.
Twilight pulled back from the kiss, with the pegasus almost falling once she did, and she closed Rainbow's mouth with a hoof. Her magic removed the dildo from Rainbow's pussy and left it on the ground.
Rainbow Dash smiled, her eyes focusing on her Mistress' face.
Twilight smiled back. "You're a good slave, Rainbow. And good slaves get rewards. On your back, and stop reacting."
Rainbow Dash immediately dropped on the ground and rolled onto her back. "What's my reward, Mistress?" she asked, her voice moving back to a more monotone one but still coloured by the residual arousal of her recent orgasm.
Twilight walked up to her, then turned around and positioned her hind legs on either side of her head. "You'll get to pleasure your Mistress. If you're good, you might get to make her cum. Aren't you happy, slave?"
"I am, Mis-"
Rainbow was cut away by Twilight lowering her backside and pressing her wet pussy over her face, barely leaving her room to breathe. Immediately, she grabbed Twilight's hind legs with her front hooves and began to lap at her sex, working her tongue on her pussy lips first and then flicking on the inside, before finally finding her clit and focusing on it.
"Right there, slave," Twilight said, shifting forward a bit, "right there. Yeah, keep going. You're my bitch. My slave. I own you. You're mine, all mine. Oh, yes!" She bucked her hips forward, pressing harder on Rainbow's face. "Yes, yes! Your thoughts don't matter. You don't have a choice. You belong to me. Yes!" She threw her head back, her wings stretching open, more and more arousal flowing from her nethers into Rainbow's mouth. "My words are your thoughts. You obey my every command. My pleasure is more important than yours. You only exist to serve me. You're-Oh, oh yes! Keep going! Yes! Yes! I-I'm-I-"
"Twilight?"
Twilight froze.
"Twilight? Is everything alright?" Starlight's voice asked from outside the door.
"I-Ah!" Twilight bit her tongue. "I... Yeah! E-Everything's fine!"
Rainbow kept licking and flicking at her Owner's sex, still holding her there. She hadn't been ordered to stop or release her, and Twilight was in no position to do it now.
"Are you sure?" Starlight asked, unconvinced.
"Yes!" Twilight somehow managed to block a moan in her throat before it left it. "I mean-Yes! Yes! N-Now go a-way... please. I-Ye-Yes! Everything's A-Ah-Alright!" Twilight shut her mouth, moaning inside it.
"...Whatever." Starlight walked away.
"Ah-ah-release me!"
Rainbow let go of Twilight's legs, and the alicorn quickly got up, her pussy still twitching and on the verge of orgasm. She stood there, panting, for a few seconds.
"Mistress?" Rainbow looked up.
Twilight looked down at her.
"When are you going to take Starlight as your slave?"
The thought of that was enough to send Twilight over the edge. She howled and fell to the ground, and then laid there panting as her orgasm washed over her. After a few minutes she got up, wiping some sweat from her brow, and removed a strand of her mane from her eyes, looking down at the pegasus who was still lying on her back. "You can go now," she said between heavy breaths.
"...then there's Starlight, Vinyl, Cheerilee... Applejack looks really pretty, and I bet Rainbow would love being with her. Trixie, that's for sure, and Spitfire as well. And then, well..." Twilight blushed a little. "I was thinking... Celestia would be nice." She looked away and fiddled with her mane.
"That sounds great, my pet." Luna ran a hoof over Twilight's wings. "When do you think you'll start taking more of them?"
"I was thinking next week. I'll probably go after Rarity first, I'm going to need outfits like yours after all."
Luna smiled. "Good. Remember what I told you?"
"Hypnotise my slaves so that they're loyal to you above me when they're with you. Forget about it when I'm not hypnotised by you. Forget that I'm your mind-fucked slut when I'm not with you, and remember it only when you tell me to. Make sure no one finds out you hypnotised me and are using me to gather more slaves," Twilight recited.
"Very well." Luna got up and grabbed a riding crop in her magic, shining black like the outfit she wore. "Now get here, slave, there's more training to do."
Author's Note
No one will write 5k+ words about this, but I felt like I needed to get it out of my system. And if you happen to see this (you know who you are, you marvelous person) know that it was only worked on on top of my daily quota.
