Immortal Equestria: Sparkling Joy

Chapter 2: Sparkling Submission

A few days later, Sparkler returned to the world of the Immortal Empire. Having made her choice after consulting with her Twilight.

As she stepped through the portal, she was received by Twilight Sparkle again, bedecked in her priestess outfit once more, standing casually with her arms behind her back. Her beautiful body once again mostly on display.

"Welcome back Sparkler, I take it you had a few days to think it over? What have you decided?"

Sparkler took a deep breath.

"My Twilight is gonna bring this to our Universe's Celestia and Luna and see what they think. In the meantime, we agreed that this was worth at least checking out. So, On the condition that I report back to her every day using this."

She held up the interdimensional journal similar to what Sunset used to talk to Twilight in the alternate world surrounding Canterlot High. "She's ok with me spending some time in this world to try things out."

Twilight clapped her hands in delight. "That is wonderful news! And I'm very glad that you're working with your universes rulers as well, we would of course have contacted them next had you been receptive to becoming an ambassador for our culture, but we had hoped to get you to try things out first. With their approval however, I believe that this all works out wonderfully!"

She beamed.

"So! In keeping with our culture, I would of course offer you the choice first as to whether you desired to try out being a slave or a mistress of a slave. In the case of the former, we could display you around, show you off in the news, and the suitable mistress or master taking you into their household for however long you choose. Or in the case of the latter, we might peruse slaves that are up for adoption or rent from other mistresses!"

She seemed very excited.

"Unless of course, there is any pony that you would prefer? You would be familiar with most of the major players in our great nation, and we could see if any of them would be amiable to adopting our very first ambassador! We could even petition Master to see if he would consider giving you the honor of being one of his personal pleasure slaves!"

Sparkler blushed.

"Well, I am a dom in my universe so perhaps I should try out being a dom here."

She considered a little more.

"As for the slave aspect...I actually prefer the company of other mares, So I don't think Master would work out all that well. In fact, I was kinda hoping...maybe...YOU would be my mistress...?" Sparkler was nervous as all heck.

Twilight Sparkle raised an eyebrow. "Well, well, well, I've made that good an impression?"

"I think it's more to the fact you look like my girlfriend...So maybe you have that edge of being a familiar face to me."

She nodded "Then As to the matter of your position, you gave me somewhat contradicting statements there. You would like to try being a dom, but you would like me to be your mistress?"

Sparkler nodded. "I don't know if you have them here but back home I'm considered a switch. A pony who can assume the dom or the sub role.

She giggled. "Of course, we do have them, but it's admittedly more of a percentile. One can be rated on the percentage that they are willing to be a dom or a sub. Can you perhaps estimate for yourself as to the ratio you prefer?"

Sparkler only had a to think a few moments to come up with her answer. "I'd say...Maybe 55% Dom, 45% Sub. Probably due to the fact my Twilight is all sub, so I always have to play the dom."

Twilight seemed satisfied. "Very well! I am personally 85/15 in favor of domination myself. I do sometimes grant special playtime with my friends or ponies VERY close to me. If you do well in your trials, I might consider such a special session, an honor for any citizen of the Empire."

Suddenly it no longer seemed as though she merely stood, but instead loomed over Sparkler.

"You will have to work VERY hard if you wish to achieve this however." She intoned.

Sparkler shivered at that. "Yes...Mistress."

Twilight's grin sharpened into a still loving and satisfied looking grimace...

"Take my right hand with your left Sparkler, and we will begin."

She held up her hand toward Sparkler, palm facing her.

Sparkler hesitated. "Uhm, before we start. I do have two requests if you don't mind, relating to when I'm your slave,"

Twilight's demeanor softened, and she let her hand drop for the time being. "Of course, name them."

Sparkler took a deep breath to steady her nerves. "Whenever possible, I would like to be tied up at all times, meaning hands trapped behind my back and maybe a crotch rope too, and... maybe I could be made to wear a cute maid outfit?" Sparkler was blushing like mad.

"Hmmm..." Twilight idly stroked her chin, her elbow inadvertently pushing up her watermelon sized breasts as she did so, causing the small black bra no end of distress as some of her areola slid into view.

"I could consider this, you would not be able to service me in some of my favorite ways, and it would put you at somewhat of a disadvantage competing for my affections with my other slaves, but I suppose you would be very cute... And I was going to train you somewhat to follow my commands… more acutely… Some of which involved bondage…"

She continued pondering teasingly.

"Perhaps if you worked very hard… VERY hard..."

"I will admit I won't be trying to win your affections...That much. I already have a Twilight that loves me dearly." She was now nervous she had offended her somehow. "Also, you don't have to if you don't want to. If you need me to be free of restraints you can do so."

Twilight shot a quizzical look at the other alicorn. "Not pursuing my affections that much? Well, if you insist… I suppose I shall simply have to use you a little bit more creatively if I am to receive any pleasure from it..." Her voice hummed with Promise.

"I will grant your request."

Sparkler didn’t seem excited though, still rubbing her arm nervously. "Uh, if you want me to try hard for your affection I will. Just say the word and... Gah!"

Sparkler covered her face in embarrassment. "This isn't going well..."

A moment of tense silence followed before a gentle set of fingers tilted her chin back up

Twilight’s face was there to meet her gaze steadily. "Do not worry Sparkling Medley. My desires and yours are the same, to have our deepest desires fulfilled. Know that with every action I make, I desire to please both of us. If you allow me to direct you, whatever you do will please me."

She patted Sparker's cheek.

Sparkler leaned into the gesture a little, closed her eyes and took a calming breath. She still gathered the courage to say her piece. "What I was trying to say is that I won't be upset if I don't win your affection, ‘cause I already have the affections of another Twilight, but I will try my hardest if you want. And if you want me to do something requiring my hands you can release me from those bonds for me to do so."

Twilight smiled reassuringly. "I know. I do not desire you to abandon her. And do not worry about the precise ways and means that you will serve me. I am a Twilight Sparkle after all... I have gotten inspiration from several books on the subject." She smiled coyly.

She held up her right hand again. "Are you ready to begin?"

Sparkler took a deep breath. "Ok. I'm ready."

"All right, your hand please." She held up her right hand, expecting Sparkler’s left.

Sparkler, in turn held out the desired hand for Twilight to take.

Twilight guided her hand so that their fingers were interlocked, their palms pressed together. Twilight ignited her horn with a glowing purple light, and recited.

"This day I, High Priestess Twilight sparkle, Mistress of Equestria, take into my possession Sparkling Medley, Ambassador to the Immortal Empire. Through this vow, I promise to bring her nothing short of absolute fulfillment, safety, pleasure, and most of all, to introduce, reinforce, and contribute to the power of love, on which our Empire stands as the greatest in the universe. Through servitude, Sparkling Medley will find joy in serving another, surety that her desires will be fulfilled, knowledge of a safety unattainable elsewhere, and a love unlike any in the cosmos, that shall empower both her and the Empire."

As she spoke, the magic enveloping her horn began to change, burning away from her normal lavender purple to a vibrant and intense neon pink, and the power was seeping down, it now filled her eyes so that they were blank and pink and luminescent, and two strands snaked out from below her chin. One seemed to leap and bury itself in just one of her mighty mammaries, the left one, where under the mass of titflesh her heart beat. The other snaked around her outstretched arm, coiling like a snake along It's length until it seemed to crash against the wall formed by the two mares' upright and clasped hands. It stopped there, at the center point between the two.

"Sparkling Medley..." Though her voice was still normal, for Sparkling it now held different meaning, different context, this was now the voice that she would hear when she would be tied up. This would be the voice that would command her forward when her legs were hopelessly strapped together, this would be the voice that would send a thrill of anticipation through her heart whenever she heard it call her name imperiously or lovingly. She would not forget the other person who held this voice, but while she was here, it would be like this, all the time, she needed only to accept it.

"Do you Submit your life as a slave of the Immortal Empire? Knowing that every one of its citizens will treat you as you desire to be treated, in ways that will only bring you pleasure? And that you in turn, will do the same?"

Sparkler took a steadying breath. “I, Sparkling Medley, do submit my life as a slave of the Immortal Empire, knowing that I shall be treated as I desire by every one of its citizens. And that I shall do the same.” Sparkler replied, with as much conviction as she would her vows when she and her Twilight eventually married.

"Then submit to me. You shall serve, and in doing so, I shall be your loving mistress, fulfilling both of our fantasies, rewarding you for your devotion, and punishing you only when appropriate... Be it to increase pleasure or encourage behavior conducive with the ideals of our Empire."

The power that had been stopped by their hands now began to snake around Sparkling melodies arm, and plunged into her relatively more diminutive breast, and when it did, she felt its power.

She felt the love and affection of every being in the Empire at once, and new instantly every sort of love expressed. Two lovers, two friends, two strangers that she did not know. And she felt this electrifying power fill her up, a joy that she could not possibly have experienced on her own, a thrill of excitement that did not fizzle at its height, but that continued up and up and up!

"You may respond by agreeing with... 'Yes Mistress'..." Came a voice next to her, or was it in her mind? Or was it a thousand miles away?

“Yes. Mistress.”

The spell dispersed, and the two mares were now simply holding hands.

Twilight withdrew her grip gently and once again put her fingers to her chin, again only slightly inconvenienced by her own bust. Now she looked down to Sparkler with a teasing smile. "Well? What are you waiting for? Get undressed. You will not need those clothes anymore."

“Yes Mistress.” Sparkler nodded and began to take off her clothes. She took off her jacket, her shoes, pulled off her socks, unclipped her skirt and let it fall, and pulled off her shirt. Leaving her wearing nothing but her bra and panties.

As she did so, one of her socks tore from her leg as with casual strength she ripped the sturdy fabric from her ankle with the ease of ripping paper.

Sparkler noticed what had happened, and blinked. “What the…? How did…? I barely tugged it at all!”

Twilight smiled enigmatically. "You are now empowered by the magic of love. You will find all of your abilities enhanced, a little bit at first, but as you dwell on the power of Love, and learn to love everypony and everything around you, you will unlock still greater power. All of the traits of being in alicorn have been enhanced slightly, for instance, as well as your stamina and your ability to take punishment of all kinds."

As she spoke, Sparkler also felt something strange within her. Somehow... she knew, just as she would know in a dream, that her mistress was bisexual, preferring the distinction between Male and Female, and leaned more heavily towards mares, with a few stallions holding a special place in her heart.

Sparkler blinked; how did she know these things? “A-are empathic powers a part of this?” she stammered as she took in this new information.

"How else would we be able to determine if a recipient of your love would enjoy it or not? It helps us avoid both unnecessary and awkward conversation when it comes to opening interactions." She said matter-of-factly.

"Speaking of which..."

She put her hands on her hips, and stood a little straighter, thrusting out her chest.

"I have not told you much about our systems of socialization, as I had deemed it necessary until I had explained about your role in your own universe, but I can tell you that if I am clothed it indicates that you should ask permission before greeting me by fondling any part of my body, or granting me a kiss, but if I were naked you would freely be allowed to do so as part of a friendly greeting..."

She grinned lustily.

"Let us work on your greetings. Come and show me how you might greet me..."

Sparkler nodded. And leaned in and kissed Twilight passionately, while also groping her breasts.

While she closed her eyes and leaned in, her hands itching to sink into the mass of tit-flesh, the moment her lips made contact with the dark lipstick of Twilight's though, there was a flare of magic, and a sharp cracking sound.

Sparkler's ass registered a sudden, sharp pain on her right flank. The sudden smack made Sparkler gasp and she pulled back, halting what she was going.

Twilight glared down at her with a look of disapproval, like a librarian catching a student eating behind the shelves. "Did you not listen to what I just said?"

Sparkler rubbed the sharp pain that was fading slowly from her flank. She looked up dumbfounded at her mistress. Twilight raised an eyebrow.

"Do you know why I punished you, slave?"

“I-I don’t understand, you told me to show you how I could greet you… was I not supposed to do both the kiss and the fondling?” Sparkler spluttered.

"And yet, I am clothed..." she stated plainly in response.

Sparkler’s eyes widened when she realized what she had forgotten. “Right. Permission.”

Twilight tilted her head in acknowledgement "Let us try again..." She adjusted her stance again.

"Show me how you would desire to greet me if you saw me on the street like this."

Sparkler shuffled her hooves together and adopted a submissive hunch, with her hands together in front of her. “Mistress, please allow me to show you how friendly I can be.”

Twilight brightened and smiled. "Of course, come here you!" Twilight opened her arms wide to indicate her receptiveness.

Just as before, Sparkler leaned in and pressed her lips against Twilight’s in a passionate kiss, while her hands sunk into her soft breasts and massaged them. Her breasts had a heavenly softness to them, pillows unmatched by any other material. Perhaps her mistress would allow her to nuzzle her face into them at some point or another.

In turn, Twilight returned the kiss, sliding her hands down Sparklers sides, then slipping them effortlessly behind her and into the rear of her panties, gently teasing and squeezing her buttocks before withdrawing them just as quickly.

When they broke the embrace, Twilight held her by the waist and looked down at her.

"Very good slave. If your powers deem fit the recipient would enjoy interactions from a mare, you can greet any citizen of the Empire in this way, and they would be eager to greet you thusly as well."

“I’ll remember that.” Sparkler decided to test how far these empathic powers went, so she tried to get Twilight to read her mind, trying to launch into an explanation of her limits…

Twilight spoke gently. “I can feel your exertions in your mind, but the clarity with which I can understand your thoughts is only because I choose to have a mental link with my personal slaves’

She then continued without moving her lips.

*I can hear your conscious thoughts through this connection, and I can speak through it myself. If you wish to communicate with me, you need only address me with 'mistress', and then your surface-level thought. Perhaps try it now?*

These words echoed through her mind, distinct from her own thoughts, but coming from her mind.

Sparkler nodded, and tried again.

*Mistress, I wish to make clear that while I prefer bondage, nothing is off the table. You may do whatever you wish to me, my only boundaries are that my bones are not broken, and (this probably goes without saying but I don’t know in this world) no killing.*

Twilight spoke aloud.

"You never have to fear any permanent or vital harm to your body Sparkler. Master abhors the sadistic, the cruel, and the unabashed and genuine torturers of the universe. He does not desire them as a part of our wonderful world of peace and bliss… and we follow in his desires for a loving world."

Twilight looked Sparkler more directly in the eye, a note of seriousness in her voice. "That said... would you prefer a safe word? Or have I not demonstrated the care that the Empire would take with your body and mind?"

"Uhm...Maybe a safe word for now would be good. Just til I get my bearings around here... This is all still new to me, at least this world's version of it anyway." Sparkler was nervous as all heck, but at the same time, excited. Finally, she could try being the sub, even if it wasn't to her Twilight.

"Very well. What shall it be?" Twilight prompted. "I personally recommend something that would not be regularly said In the Heat of passion of course, but also something fairly short so that it need only be spoken or thought with minimal effort."

Sparkler cast around briefly for something easy, but not something that would be mistaken for a passionate moan or gasp. "Hm... Maybe Apple?"

Twilight inclined her head. "That's good enough I think... now, for full disclosure, Starlight Glimmer and I have been working on utilizing safe and rather kinky mental manipulation spells. Would you perhaps like to participate in some of these experiments?" She smirked slowly, curious what Sparkler would say.

"W-what do you mean by that?" Sparkler could feel herself getting wet already.

"Cognitive alterations… for the purposes of pleasure I assure you. Would you like a demonstration?"

Sparkler gave a slight nod, her mind too curious now to say no.

"Starlight will be pleased... let's try it out."

Twilight ignited her horn, and a short flash of light lit the chamber.

At first, nothing seemed to happen... but then she felt a pressure in her frontal lobe, like her brain was being drawn like a magnet towards Twilight.

Or rather, more specifically, Twilight's enormous, larger than head size breasts. When she realized this, the magnetism effect intensified, and she was inexorably drawn towards the massive slightly oblong pillows of flesh.

It was not a telekinesis spell, her body now, and for what seemed to be destined to be the rest of her entire life, now revolved around worshiping and snuggling in between those breasts.

Sparkler leaned in, and started groping Twilight's breasts as she snuggled her head in between them, wanting to worship them as much as she could. She sighed in content and closed her eyes.

Another sharp Crack split the air, and at the same time the spell was broken, but Sparkler didn’t feel a searing and sharp pain on her flank this time. It was merely Twilight snapping her fingers again.

Sparkler gasped and stopped what she was doing. "Whoa...So that's what you meant."

"I'll forgive your unauthorized transgression into my personal space this time, as I did cast a spell on you. Are you perhaps familiar with the want-it-need-it spell?" Twilight’s voice came from above her.

Sparkler realized what she did wrong. “I was never supposed to actually act on that was I. I’m sorry. I just wanted to worship your breasts as much as I could.”

"I am aware, but I was expecting your actions, it was my spell effect after all... And it is 'I'm sorry, Mistress.'" Twilight Chided.

"Doh, right. Sorry, Mistress."

*Damnit this could be going better*. Sparkler thought.

"You also failed to answer my other question. It seems as though we will need to work on your listening skills..." Twilight snapped her fingers, an unnaturally loud crack of noise cutting through the air, and Sparkler lost sight of her Mistress. Indeed, her eyes were covered by a silken blindfold.

“Sorry! Sorry Mistress. Yes, I do know of the want-it need-it spell. My Twilight told me about it. Gah. I’m not a very good sub at all.” She lowered her head in shame.

There was a moment of silence. Undistracted by the sight of her Mistress, she could now hear the rustle of fabric and two clacks of Twilight's shoes as she took two steps forward.

She could feel the hints of her Mistress's tingling aura of power. The power of each step as her titanic weight could be felt through the stone.

Then... as gentle as feathers, Twilight encircled Sparkler with her arms. Her face was pressed again into the cleavage into which she had dove headfirst a moment ago, and a tender hand held her head as Twilight spoke.

"That you desire to improve yourself as my slave does you credit. I beg that you do not overthink things, as I did in my previous life, everything that happens to you is happening for a reason, and my punishments are simply the new way that you will learn. And hopefully with the pain comes pleasure as well yes?"

"Yes. Mistress."

Indeed, Sparkler was finding all this pleasurable.

The mass of warmth and softness that was her Mistress withdrew from her.

"Good. Now, back to the lesson."

There was a pause as fabric readjusted, then silence.

"You are going to undress me. No magic, and as you do so, you are going to answer some questions for me, you understand?"

"Yes. Mistress, do you wish that I remain blindfolded?"

"Given that I decide how you will dress from now on, yes."

"Very well. Where would you like me to start Mistress?"

Sparkler took a deep breath. This was gonna be tough.

"Good girl.." She purred. "You may start with my habit. Take it off and throw it aside. While you do so, tell me some of the things you have done sexually with your Twilight, I am curious to hear."

Sparkler slowly moved her hands up and touched them to Twilight's face, feeling around for the Habit. Once she located it, she easily located the flap, peeled it back, then tugged it off her mistress, tossing it aside.

"Well, some of the things I have done to her is tie her up, in a variety of ways, spank her, penetrate her with a dildo, sometimes I triple penetrate her, with a dildo for all her anal, pussy, and mouth."

Sparkler decided to progress downward, slowly but surely removing Twilight's clothes. Due to being blindfolded, she had to feel around for every fastening that would allow her to remove her mistress's garments, which meant she had to feel around her mistress's body.

"I have also used a vibrator on her, Really the list can go on because like me, her only boundaries are that I don't break any bones, or kill her."

Twilight’s voice purred at her. "Hmmm, as you've stated before, and I will respect your same boundaries."

She felt hair whipping by her hand as her mistress tossed her head now that her mane was free of her restrictive habit.

"My choker next, and did you have any friends to participate or share in this?"

Sparkler nodded and moved her hands down to her mistress's neck; she felt a choker indeed. She felt around until she found the buckle, and unclipped it carefully.

"My Twilight and I keep it to ourselves. She was, is, embarrassed that she, a princess, could be into this sort of thing. Sure, gave me a shock when she confided in me this news."

"And how does that make you feel? To be embarrassed and ashamed of the things you love?" Twilight sounded a bit forlorn.

"My sleeves now” She added casually.

Sparkler remembered the sleeves to which her Mistress referred, a mere suggestion of a top that really only covered her arms, leaving her chest exposed.

"Personally, I do not feel embarrassed. But in my world, this isn't something you can casually bring up. Some ponies would rather keep it a secret. And Twilight does not feel ready for everypony to know she's into this. So, until she feels comfortable, we agreed to keep it between us."

Sparkler moved her hands to Twilight's sides, and down her arms until she felt the fabric. She gripped both sleeves and gently pulled them down and off Twilight's arms.

While she did this, Twilight moved her arms to helpful angles, allowing the sleeves to slide off effortlessly. "What do you suppose holds her back? Fear of judgment? Fear that she has become 'too lewd?' Perhaps she fears that she is the only one?"

After the sleeves were removed, she spoke. "Now my vest. I will help you in saying there are little sleeve rings under my upper arms, so you’ll be grateful that you needn't fumble this one."

Sparkler nodded appreciatively “Thank you, Mistress.”

Sparkler moved her hands up Twilight’s arms til she felt said rings under her upper around. She felt buckles on them, so she undid those, then moved her hands to Twilight’s shoulders to let the vest fall onto the ground. “My best guess would be fear of judgement. She knows other ponies are into this too, but it’s a minority.”

As Twilight helped shrug off the garment, Sparkler could hear the whoosh of her wings unfurling to their full length before settling back down. "What if she didn't need to feel such shame? What if she could openly and joyfully display her love for you? And that others would understand it as such without judgement?"

Again, she added her direction. "Now my skirt."

Sparkler moved her hands down her mistress’s soft form until she reached her waist. She felt around for the button above the zipper, marveling at how WIDE and robust her hips were. When she finally slipped the button off, then pulled the zipper down, she gripped the fabric that was her skirt and pulled it down, letting it fall on the ground.

“You mean like here Mistress?”

"Exactly. Master believes that the repression of pleasures is not conducive to a loving society. he believes that as long as people are expressing love for one another in a genuine and benevolent way, that all expressions of that love would be permissible. But of course, in order to do that, one would have to have built the societal framework to allow the flourishing of such pleasures without the risk of impeding on another's pleasure."

"Did you stare at my garter belt when I crossed my legs, slave? “She asked suddenly.

Sparkler spluttered. “I-I beg your Pardon Mistress, I-I’m not quite sure what you mean.”

"From before, while we talked, did you admire it? My ass and thighs are large enough that I believe you would have received a very good view?"

Sparkler quickly thought back to before when they talked. And realized that yes, she did stare at her voluptuous thighs, her sturdy garter belt… the bulge under her panties... Sparkler could feel the blush creep across her cheeks. “I…I did. I’m sorry if that was rude of me, Mistress.”

"Far from it, another thing you shall learn about the Immortal Empire is that every exposed part of our body is deliberately chosen. We show what we desire to show, and we display this beauty for ourselves, but also for the pleasure of others. Here, there is no shame in staring, especially if somepony has decided to go naked!"

Sparkler’s face was red-hot now. “O-Ok.”

Twilight chuckled warmly. "I was actually going to ask you for your opinion. You suppose you would enjoy worshiping my ass as well?"

Sparkler gulped. “M-Maybe someday.”

Twilight sounded pleased. "Very well, I do know there is one part of me you have enjoyed thus far... it's time to remove my bra, slave."

Sparkler reached around her mistress to obey, but Twilight gripped the first hand that attempted to reach behind her. "You have answered my questions well, and you will be rewarded. You will have a minute to worship my breasts once they are free. Only one minute. You understand?"

Sparkler smiled. “I understand. Thank you, Mistress.”

She reached behind her mistress, careful to keep her hands on her body to ensure she was going to the right place, and quickly found the buckle that would release Twilight’s bra. She unclipped it and it fell onto the ground. Sparkler wasted no time in moving her hands to grope her mistress’s big breasts, and alternate sucking between each nipple desperately.

They were so enormous and soft, that her hand could practically be lost in its adipose. As she sucked and licked, she would feel that her mistress’s areole was about as large as her index finger and thumb when connected in a circle, with a nipple roughly as thick as her thumb. The taste was divine, though no milk sprang fourth, a strange sweet and salty taste titillated her tongue as the nipples became erect, firm, then completely immovable by her comparatively soft tongue.

*10 seconds...* came the comforting voice from her mind.

Sparkler had ten seconds left, she wasted none of it as she groped and sucked more forcefully. At the end of the ten seconds, she pulled back, giving Twilight’s breasts one final squeeze as she did so, before removing her hands.

"Did you enjoy yourself slave? Did you enjoy your treat?"

Sparkler nodded, a bit slack jawed. “I did. Thank you, Mistress.”

"Good, now it is time for you to remove my garter belt, take your time, and make sure that you do not rip my stockings, or you will be punished very severely."

Sparkler nodded and carefully undid the clasps of her garter belt. With as much care as she possibly could, she pulled down, keeping in mind her new strength. She pulled down her stockings, alternating between socks as needed. Eventually, she reached her Mistress’s hooves. Thankfully without damaging her socks.

When she had both of the stockings on the floor, she heard the clip clop of her two heavy hooves clacking to the stone floor on either side of the pile. Clearly she had also removed her small black heels.

"Stand up now, slave" Twilight commanded.

“Yes Mistress.” Sparkler did so and got up on her hooves.

"I think your listening has improved after our little lesson alone has it's not?" Twilight pried coyly.

Sparkler nodded. “I guess you could say I’m a quick learner. Though, I think part of the problem was just me still trying to wrap my head around all this, Mistress.”

Twilight’s hands rested gently on her shoulders and rubbed them reassuringly and gently. "That's to be expected, you're being introduced to lots of new terminology, new concepts, and even an abstract and different way of thinking about the entirety of your life…" Another gentle clack on stone, Twilight's hoofsteps stepped imperiously in front of her.

"So, I think my final question, my next order, rather, will be far simpler in concept, familiar in terminology, and hopefully easy to understand…"

Sparkling could hear the rustle of fabric. But Mistress had already been undressed? What could possibly be… Then she remembered the bulge that she had seen nestled between Twilight's pillowy thighs. The panties that strained to hide an organ that shouldn't belong on a mare…

Sparkler’s eyes widened, not that it would have mattered since she was still blindfolded. She realized the most probable thing her mistress was about to ask of her. Give her dick a nice sucking. Sparkler blushed. Her nervousness returned in full. She had never done anything like this before. So acutely tuned with her senses she was, that the gentle weight of the silken but impossibly tough material of Twilight’s underwear falling to the ground sounded like a cannon shot in comparison to the tense silence that fell.

Then Twilight spoke. "Spread your hooves to your shoulders."

Sparkler complied and spread her legs to shoulder width.

Something thick, rigid, and HOT impacted solidly between her legs. It staggered her just a little bit at its sheer power, and it smacked her still panty covered entrance of her pussy, and was long enough to smack her buttocks, which tensed with the impact. "You are going to service me."

In that instant, Sparkler regained her vision, and was overwhelmed by the sight of her mistress, naked and glorious in her beauty, and when she looked down, she saw the weapon that had spanked her...

Sparkler stared at the cock. Sweet Faust it was big. “Uhm…what you would like me to do specifically Mistress? I-I’ve never serviced a cock before.” She stammered; she was beyond nervous now that she was gonna screw up

Twilight put another reassuring hand on her shoulders. "Do you trust me to guide you?" Her cock pulsed with regular, powerful throbs as her blood pumped through the mighty organ, practically like a vibrator on a very low setting.

Sparkler felt some of her tension ease as she realized she would not have to improv without direction. “I do. Mistress.”

"Then take two steps back, slowly."

Sparkler did as she was told and took two steps back. Not taking her eyes of the captivating dick.

*Sweet Faust, who knew mares with dicks could be such a breathtaking sight*. *I wonder if there’s a spell to give* any *mare a dick. I might be able to convince My Twilight to try it out…*

Twilight spoke aloud in response to her thoughts. "Perhaps, if you prove yourself a loyal and entertaining slave, I will consider granting you such a boon." She grinned down at Sparkler, her statement reminding her slave all too vividly that she could not hide her desires and thoughts from her mistress.

"Now, kneel down, and tell me what your goal depth is for today." Her smile turned smug and enigmatic, clearly daring her to ask what she meant.

Sparkler blushed, remembering her mistress could hear her thoughts. And goal depth?

“Do you mean how far in I want your beautiful staff to go Mistress?” She posited, taking a position on her knees as her mistress had requested.

"Very good… You are correct. Though I think you miss the point of you being the one to choose. You will have to consider carefully that you have not built up a gag reflex, and that even if you did, there are a few amateurs who can take such a member without faltering. So, your choice of how far you wish to go is in and of itself an expression of how much you trust me, and how much you love me..."

Her cock bobbed once to accentuate her point.

"The deeper you manage to go, the deeper your devotion, but if you should fail, I will satisfy myself another way, and you will be punished."

Sparkler nodded. “Uhm…maybe…halfway to the back of my mouth to start? If that’s alright, Mistress.”

She raised an eyebrow "Barely past my tip?"

“Is that too little Mistress? I’m sorry, I, I just never done this before.” While she was saying that, she had lowered herself down to her knees, and now struggled to find a good position to sit her hands.

"I just believe that you can try a little *harder* than that… Slave." her lips pursed as she looked down at her more petite slave.

Sparkler gulped.

“Ok…all the way to the back out my mouth?”

"Much better. Crawl forward on your knees, kiss my tip, and thank me for the privilege of serving me."

Sparkler crawled forward on her knees as instructed and kissed the tip of Twilight’s cock.

As she drew closer, the sickly salty musk of it temporarily overpowered her nostrils and sent a shiver of pleasure down her body. When she finally touched it with her mouth, it nearly jerked free of the grasp of her lips, but she managed somehow to hold it and keep all of her teeth, leaving a little trail of pre-cum drooling from her bottom lip.

“Thank you for the honor to serve you Mistress.”

It was easily as thick as her forearm, and it dribbled freely with clear, watery pre-cum, the head flaring only slightly more than the entire body. Sparkler was unsure of just what length a cock was “supposed” to be, but she was fairly certain that this was an abnormal size.

"Good girl, now..."

She walked past where Sparkler was kneeling on the floor, letting her cock temporarily press against the other alicorn's cheek before it slid off and sprang into place, facing the direction she was walking. She arrived at her destination, and set herself languidly on the cushioned couch that had been sitting in the room a few feet away. Once she was sufficiently reclined, she raised one hand, thumb, and middle finger together.

"Worship me NOW” She intoned, and snapped her fingers.

The magnetizing sensation again, this time stronger than ever, now her eyes could not physically un-glue from their deliciously thick and powerful target: The head of Twilight's cock.

All other thoughts were unceremoniously smashed to the floor as her brain registered and immediate starvation response. She had to get her lips onto that cock tip NOW!

As fast as she could, Sparkler crawled in her knees over to the couch, opened her mouth wide, and leaned forward so her mouth took her mistress’s large dick. She felt it hit the back of her head and she somehow had the sense to remember that’s as far as she wanted to go. So, she stopped right there.

Somewhere in her musk addled brain, her ears managed to register another sharp clicking sound.

The abject obsession of her mistress's cock tip vanished, and Sparkler realized that if her mistress had altered the location of the spell even a few inches down, she might have attempted to jump for the relatively petite medial ring that was still a good 3 inches away from her muzzle, or, more devious, had she put it at the base...

A shudder shot through her spine as to what could've happened then...

"Well? What are you waiting for?" Twilight's horn flared, and a sharp smack to Sparkler's buttocks punctuated her commanding tone.

Sparkler moaned onto Twilight’s cock at that smack, and started moving her head back and forth, her tongue also feeling up that cock.

She moaned in pleasure, it was unlike anything she had ever felt before, and she was loving every second of it. The scent of her mistress’s cock, the taste in her mouth.

So this is what being a sub is like. Now I see why my Twilight likes it so much.

"Mmmm..." Twilight gave a satisfied little moan herself, and languished back in the cushions, one hand casually feeling up her own breast.

"Isn't it wonderful?" She sighed. "Knowing that every action you make is felt, is appreciated, is loved, by another?"

A new sensation now, a swelling in her chest, the love that Twilight mentioned, pouring out from her, and into Sparkler. Just a trickle, enough for Sparkler to feel her mistress's presence even when her eyes were closed. But it was the sort of trickle she felt that came from the smallest leak in a great dam.

"Mmmhmm."

Sparkler moaned as she continued her work. Savoring the taste and scent of her mistress's cock, wanting it to never leave her.

"And do you know that I love you? Can you not feel it in every action that I take? In every word that I speak?" She slid her other hand gently into Sparklers two toned mane, not pressing or resisting, but riding her head back and forth as Sparkler bobbed happily up and down.

"Mm mo mmphmm." (I do Mistress.) Sparkler replied as she continued happily with her work. She knew, even though this was only her second encounter with her, that her mistress loved her. And Sparkler loved her mistress.

Twilight herself was starting to breathe a little heavier, and her fingers began to grip at Sparkler's head, one at a time, while her palm continued to rest gently and ride between the gently swaying ears. Sometimes her index and middle finger would tense as she reached the apex, encouraging her back down, other times her thumb and pinky would grip her head gently as the cock filled her throat entirely, encouraging her to stay down just a little longer.

"I love you Sparkling Medley, all that you are, and all that you will be."

“Mm Mmm mo Mmm Mmhmm.” (I love you too Mistress.)

Sparkler giggled at the thought, she didn’t think she would be saying that to anypony other than her Twilight.

Subconsciously, her hands found their way to her own pussy, and she felt it’s wetness. She was really being turned on right now.

"Hmmm... let me help you with that…" Twilight cooed.
Her breathing was now steady but audible even above the eager shlicking of Sparklers lips.

At first Sparkler did not know what she meant, but a subtle twinkling of magic later, she felt something glassy, smooth, and bulbous slide along her buttock, smoothly and mechanically pushing aside one of her asscheeks and seeming to be moving inexorably towards her anus.

Sparkler’s eyes widened. Was her mistress gonna penetrate her anus?

"We...hah... need to train you up so that you can experience...MMMmm... EVERY pleasure the Empire has to offer, and I see no reason why this training couldn't begin.... mmmm... now…"

Her self-groping was becoming more forceful, and her fingers were now tight on Sparkler's skull, again neither resisting nor encouraging her enjoyment of her mistress's cock, but any deviation from this activity would likely meet with resistance.

“Mmm.” Sparkler’s pussy was getting closer to bursting. She was shivering in anticipation as she continued to suck her Mistress’s cock happily.

The buttplug nuzzled gently up against her anus, gauging the rocking back and forth of Sparkler's body. Once it was sufficiently synchronized, its tip pressed ever so slightly harder, breaking the surface, and sliding in gently.

"You will… hahh... Be wearing training gear in your holes in addition to your chosen outfit... ~ahh... ending only… When you can take…mmmff... my length…"

By this time, she had summoned soft purple hands to knead and fondle her own breasts, while her right hand slipped beneath even her avocado-sized balls to the marehood that glazed the backside of her testicles with cum.

“Mmph?” Sparkler was confused. She understood the training gear bit, but she only felt the one currently penetrating her anus.

"Do n-not trouble yourself...MMMFF... slave! Are you not mmmmfffucccking...g-grateful that I allow you to pleasure yourself?"

Her hips were twitching now, bucking up and down, Sparkler could practically hear the sloshing below her chin as Twilight continued to finger and fondle herself, while a hand on her head was starting to squeeze very tightly.

“Mm Mmmhmm.” (I am Mistress.)

She continued sucking on her mistress’s cock. Inching ever so closer to bursting.

The glassy buttplug seemed to have reached an impasse. It was bulbus and segmented into ever-increasing sizes of spheres stacked atop one another, and her entrance couldn't take much more! She was stuck on the largest size, the skin around it juuust barely too taught to fully claim it without effort.

Twilight licked her lips lustily and gasped "You can cum when you take the last knot! Mmmmm... fuuck, then you better get ready to have our... guaaah... lunch...!"

Now Sparkler was ready to burst, but she hadn’t taken the last knot yet. She did everything she could short of pushing it in herself to take it.

After a second, she let out a loud moan as the last knot finally went inside her. When it did, she let her pussy burst and cum came dripping out. Fuck that felt good.

As she shuddered and moaned, the powerful extremity in her mouth bucked once, twice, then became as rigid as steel before a fountain of hot, gooey liquid erupted from the tip she so lovingly worshiped.

"CUMMINGGGAAAAHH...MMMMMmmm!" Seemed to be her mistress's only warning.

It came in pulse, after pulse, after pulse, each burst somehow just as forceful as the last. Too much for her throat to clear with her mere mortal swallowing reflex.

Sparkler was forced to pull out completely and she coughed up cum. She did not expect that much cum. Though she probably should’ve seen it coming with the huge cock.

"Mmmm... If you can't catch it in your mouth, use your body slave!" Twilight continued to finger herself, and used her free hand to continue stroking her mighty shaft.

Finger thick ropes of cum still spattered from her cock as she rubbed herself to completion.

Sparkler nodded and used her hands to catch the rest of the cum coming from her mistress.

“I’m sorry Mistress. I just wasn’t ready for that much cum.”

As the eruptions of cum wound down, Sparkler was left with practically a full handful of thick, slippery liquid.

Mistress leaned back in her chair, huffing for a moment, leaving her drenched in her mistress’s cum, holding roughly a cups worth of the stuff.

Finally, she breathed. "No pony is truly ready for the virility of our beautiful world's alicorns slave, you will learn in time."

Sparkler nodded, and glanced down at her cum filled hands.

“What do you wish me to do with this cum Mistress?”

She asked.

"As I said, this will constitute your lunch for today. you will find an alicorn's cum is one of the most nutritive substances in the world, short of alicorn breast milk that is!"

"After you had your lunch, you will clean up my cock, and then you will remove your dirty bra and panties and put them atop the pile I have made of your old clothes." She gestured to a neatly folded stack of clothing that contained her jacket.

Her cock was not rock hard anymore, but in nor was it retreating very far into its sheath, and cum spattered the first quarter of it where it had burst from Sparklers mouth.

Sparkler nodded. “Yes Mistress.”

*Cum is one of the most nutritious substances here. Imagine that.* she thought

Sparkler raised her cupped hands to her mouth, and began to drink her mistress’s cum like a bowl of soup, and much to her surprise, Mistress spoke the truth. Not only was it delicious, but she did also feel herself getting a lot of nutrition from it. It was so thick, a nutritious protein shake that when she finally emptied her hands and lick them clean, she actually felt nearly satiated...

Mistress's fuckrod was still slathered in the stuff though...

Sparkler readied her tongue, leaned in, and started licking her mistress's cock clean. Savoring the taste. She licked her tongue up and down her mistress's long shaft a few times before moving her tongue in circles around the cock. Making sure to get every inch of it.

As she worked, Twilight leaned over her and quickly and expertly undid the clasp of her bra, catching one end of it and sliding the cum-slicked garment off of her breasts. She used magic to float the garment so that it was nestled gently atop the other clothes, not bothering to clean it off.

"Now, kiss my tip and thank me for your lunch." she cooed dotingly.

Sparkler nodded and kissed the tip of her cock. "Thank you for my lunch Mistress, it was the best thing I have ever had." That was the truth, it really was the best thing she had ever eaten.

"Aww, you're very welcome slave! Now, on your hooves, and take off your panties for mistress. Remember to show off for me!"

Sparkler only then realized that her bra was missing. Mistress must’ve taken it off for her. “Yes Mistress.”

She obediently got onto her hooves, pulled down her panties, and slowly turned in a circle to offer her mistress a good view from all angles. Her hips swayed with each step, and her ass, which, like her breasts, was a little larger than the average mare’s. Her hips flaring out from her shoulders a good inch or two, and more toned.

Sparkler blushed. She was doing so many things she never thought she would, and she was loving it.

Twilight watched the show with a lustful gaze, drinking in her new slave in all of her glory. Once Sparkler had finished her short and sensual striptease, Twilight held out her hand expectantly.

"Now give me those, and you have a decision to make before we go upstairs and get you settled: How would you like mistress to clean you up?"

She allowed the impact of the words to sink in before speaking again. Sparkler had not even noticed that her body was still covered in her mistress’s heavenly cum.

"You have two choices: mistress can either clean you up with her magic, we get you all dressed up, and you can come upstairs with me, and I will show you to your room and such."

a predatory grin split her face.

"Oorrr... mistress can do something extra nice for you, lick you perfectly clean and play with your cute little body. But in return, you are going to have to earn your amenities the hard way... And it is unlikely you will be able to gain all of them by the end of the day, so I will have to make… Other… Arrangements in that regard..."

Sparkler bit her lip, easy or hard were her choices essentially, and on one hand, she wanted mistress to play with her, but on the other hand, she didn’t really care for sleeping on the floor or in a cage tonight, so…

“Magic would suffice mistress. Uhm, while I am cleaned up, may I ask a question relating to your holy shaft?”

speaking of the titanic phallus, it was now halfway sheathed, and seemed unlikely to retract more, clearly even the fantastical anatomy of ponies were incapable of containing such a mighty cock.

"Hmm? What is that slave? ask your question while you stand still."

She passed a hand over Sparklers body, and the cum began to wipe away as if a cloth brushed it aside. On her coat she could feel the subtle electric tingling of her mistress's power.

“It’s more to do with what the implications could be. I’ve been told how foals are made so…I was wondering, could Alicorn mares impregnate other mares in this world since they have cocks?”

Twilight nodded. "The short answer to your question is yes, alicorns can sire foals in mares, other futas, and even males with an application of enough creative magic!"

She giggled a little at this. "Essentially with a cock we have the same ability as males to impregnate any fertile ground. And it just so happens that alicorns have on average much larger cocks than males. For instance, my own brother shining armor is bit smaller than I am, but he is exceptional compared to an average unicorn male, and my cock is a few inches shorter than big Mac, who earns his title by a respectable margin compared to all but the other princesses."

She considered. "The longer answer is that nopony can impregnate one another without express permission and a blessing from Master, or another ruler outside of designated breeding years. Being immortal, if we allowed the natural breeding cycle, planets of the Empire would soon be overrun with a population crisis. It was decided to limit breeding to once every 20 years or so, and within those breeding years, a limited number based on the total population. With the intent of raising that generation of children to the utmost of our ability during that time."

She had finished cleaning up Sparkler, and Twilight patted her cutie mark affectionately.

"Does that answer your question sufficiently slave?"|

"It does. Thank you Mistress. I had a feeling there might be some birth control with everyone being immortal."

*Note for the future, ask about what happens to foals when they're born...and maybe ask when the next breeding time is.* Sparkler took a mental note.

“All in due time slave” Twilight giggled

Damn, one of these day's Sparkler would remember that her mistress could hear her thoughts.

Twilight looked over to the pile of clothing next to the mirror. "I will be writing a note to your version of Twilight sparkle. Why don't you help me with its composition?"

She smirked as she snapped her fingers, and a quill, ink, and parchment appeared floating in the air in front of Sparkler.

"Uhm, that’s alright Mistress, I can just do it myself, you don't have to trouble yourself with my assignment."

"Oh no slave, you misunderstand, I desire to write to the alternate version of myself independently."

Her smirk widened.

"I just wanted to give her some personal reassurances. In case she had any doubts…"

Oh. Well, this was gonna be interesting.

"Oh...Alright." Sparkler blushed. "Though, to talk to her we need my journal that I brought. That's the only way to get a message to her."

Twilight waggled her finger back and forth. "You forget my power slave, I was able with a thought to redirect your interdimensional travel, and we now possess a physical link to your universe in the form of this mirror".

She gestured to the mirror to punctuate her point.

"Teleporting a note to a relatively close location within your universe through this wormhole is a trivial task for me. Since it is for all intents and purposes, a location that is as close as however far away from the mirror in the other world it is."

"Well, I guess it would be Ok. But would it be alright if I sent my first report through the journal and let her know a letter from you is coming? I feel like she would appreciate the heads up." Sparkler gulped. She hoped her Mistress would understand.

Twilight considered this for a moment, then nodded. "Very well, you were very polite, and your reasoning is sound. Both of these I appreciate." Her hands withdrew from behind her back and instead crossed in front of her arms, cradling her massive mammaries.

"Read aloud to me as you write, and I will make corrections as necessary, and be quick about this."

Sparkler nodded, summoned her journal, and began to speak as she wrote.

"Dear Twilight, As promised this will be my first daily report. I have officially submitted to being this world's Twilight's slave, and so far things are going well. Now I know why you like being a sub so much. It's actually really fun.

It's true what they say about this world, everyone loves everyone. I have felt this for myself through new empathic powers. I will explain this in more detail, but for now, I need to make this quick per my mistress's instructions. So, for now I will tell you this. Your counterpart here wishes contact with you. She is ready to send a letter through the portal she used to first bring me here. I hope this is ok.

I shall contact you again soon.

Forever yours,

Sparkler

P.S. Don't you worry about a thing. No matter what happens, I will always love you as I always have. You and our kids mean everything to me."

She nodded and glanced at her mistress. "I hope it's ok I added that bit in, I just wanted to let her know I wasn't cheating on her. Because that's sadly a thing that happens in my world."

Twilight nodded in understanding. "That is quite all right. Now, take the parchment and quill I've given you and take a letter." Sparkler was reminded of the writing implements floating just near her at arm’s reach.

Sparkler nodded and took the quill and parchment

*Huh, Now I feel like my world's Spike. Hehe.* She thought to herself.

Twilight smiled and cleared her throat.

"Dear Twilight Sparkle, I hope this message finds you well.

Your lover, now my slave, has informed you of the ease and comfort of falling in love with this world created by my Master's love.

I merely wished to send my own personal assurances that although her life is now changed forever, it does not come at the exclusion of yourself, and at the end of her training, she will be able to share this experience with you, and with the entirety of your world.

I bid you joy on that day and every day leading up to it. I will send to you now a token of our combined love and effort for each other and for you. I hope that you find it enjoyable.

all for love,

High Priestess Twilight Sparkle

P.S. The eyes of the purple pony fall upon knowledge in light..."

That ending phrase was strange and enigmatic, but Sparkler felt as if it was indeed part of the letter.

As she jotted down the last line, she spoke up. "Uhm, If I may, what does that ending phrase mean exactly Mistress? Is that the token you wish to send her?"

Twilight held out her hand, and the parchment in Sparklers hand was tugged gently away and into her grip.

"Oh, just something that I developed when I was a filly, and have since used as a jumping off point to contact other versions of Twilight. I once thought as a filly that if I were to meet either another version of myself, or myself from a different time after I developed it, that I would use a special identifying phrase that might confirm that they were me. Of course, the first time I really did encounter myself from the future, I was so flustered, and my near-future counterpart was so distraught that I completely forgot about it!"

She giggled, and trotted over to the pile of Sparklers clothes. "If your version of Twilight sparkle is even remotely similar to mine, the phrase is vague enough that it covers all lot of near-dimensional variations of myself, so she will either have the same or a similar phrase."

She used her magic to roll up the scroll, seal it with a ribbon that appeared out of nowhere, and then placed it in front of the pile of clothes, atop which were Sparklers sopping wet panties and bra.

Twilight glanced slyly over at Sparkler before gesturing to the pile. "As you won't be needing these, I was going to send them back to your version of Twilight..."

Sparkler nodded. "As you wish Mistress. I shall explain it to My Twilight if she responds to my message in the journal."

Twilight looked down at the pile, smirking a little at the still sopping wet and gooey cum that covered the top two articles of clothing. "Very well, after I send this, we need to get you dressed and settled into your room."

She snapped her fingers, and the note, along with the 'tokens', disappeared. "Now then, stand up, and we are going to get you all ready to go."

Sparkler nodded and stood up on her hooves.

Twilight approached her, and stood directly in front of her, such that her breasts were level with Sparkler's eyes. Below, her cock swung freely and loosely.

There was a puff of magic, and a frilly black and white maid outfit appeared next to Twilight, adorned in the corner of the tiny white apron with her cutie mark.

"I am going to use a measuring technique developed by Mistress Rarity to measure you, your job is to stay still, do you understand?"

"Yes Mistress."

"Good girl"

Twilight nodded and placed her hands on either side of Sparklers hips, and began to slowly trace them around the circumference of her body. When she reached the center point just under her belly button, she raised her hands slightly higher, and repeated the gesture along her waist. Soon her powerful and slender hands slid under her breasts, then, in the next pass, they were pressed atop them.

Twilight gave a possessive little squeeze, bringing her fingers together with Sparklers breasts offering the barest resistance, and giving them a little twist before dropping them, smoothing them out, and raising her hands once again to measure along her slave's collarbone.

Sparkler let out a small gasp when her mistress twisted her breasts, but stayed still as ordered.

"Good girl, just a little longer before we'll get you into your pretty new dress. By the way, your crotch rope that you requested… Did you want it to squeeze your little pussy so that it looks nice and puffy? Or do you want it to go right over your training dildo so that it won't fall out as easily?"

As she did this, the skirt that floated next to her was gently tugged looser, or sewn tighter as mistress determined by the measurements of her hands.

"I-Is both an option Mistress?"

Twilight’s horn flashed, and Sparkler experienced another sharp smack to her bottom.

"Don't get greedy little slave, or you will get more than you bargained for.” She warned. "Choose."

Sparkler gasped at the smack. Then nodded. "Right over the training Dildo, Mistress."

"Better." The word didn't have the same ring as her praising 'good girl's from before.

Twilight finished her measurements by gently wrapping her fingers around her slave’s neck. She held the fingers there, staring down between her breasts.

“I wonder if you ever wanted to play with just how much breath you can keep while I play with your pussy… I can make sure that you will never get another molecule of oxygen into your lungs while I do it as well. My little Starlight loves it.”

She rippled her fingers, demonstrating their power, but not gripping hard.

Sparkler gasped, then gulped. "I-I'm willing to try it...Mistress." The fear was clear to see on her face.

Twilight gave a slow and satisfied smile. "Good, another time maybe."

She released Sparkler's neck. "Arms forward, help me put this on, and I will tighten it for you."

Sparkler nodded and stretched her arms forward obediently.

Twilight used her magic to slide the maid outfit along Sparkler's arms, and she immediately noticed that the sleeves were perfect, in that they were just tight enough to be restrictive, without cutting off blood flow.

She experienced the same when the dress was finally secured to her body, and Twilight used her magic to snap the clasps quickly and expertly at the neck and waist, and zip up the back.

"Turn all the way around for me, slowly, show off how pretty you are for mistress." Twilight encouraged dotingly.

Sparkler nodded and slowly turned around for her mistress to see. She caught a glimpse of herself in the mirror, and she had to admit she looked pretty darn cute.

Twilight nodded approvingly when she returned to front facing position. "Now, how would you like me to tie up your arms?"

"Straight down behind my back, Please Mistress. Make the bonds as tight as possible without cutting off circulation."

"Believe me, if you were going to make your arms useless to me, I would make sure that you are limited only to the consequences of them being completely useless..."

Twilight performed a circular motion with her upraised finger, and dark purple nylon ropes encircled Sparkler's waist, before they snaked both up and down, half of the rope forming a little belt before dropping a loose end of rope in front of Sparkler's crotch. The other half of the rope began to hug her body and her maid outfit tightly, constricting her like a snake in a crisscrossing pattern that framed her breasts and wing joints in rope.

The predatory rope then latched onto her already joyfully positioned arms, binding them first by the wrists, which drew taught enough to elicit a pain response before slackening the barest amount so as to fulfill her wishes. It then snaked up her arms, once again tightening with the strength of a boa constrictor before finding just the right position to allow her not to be in pain. Soon her arms were well and truly immobile, no matter how much she struggled. If she even had any thoughts about struggling anymore…

"Those ropes will also keep you nice and tight, no matter how much time passes, and no matter how much you wiggle, you'll remain my perfectly tied up little bow, and you'll never have to think about your pitiful, useless hands, except when I am railing you from behind, and your little brain tries instinctually to hold me back… That will be fun I think."

"Yes Mistress."

Sparkler felt a shiver down her spine as she was tied up. Back in her world she would always secretly tie herself up because she enjoyed the feeling of controlled helplessness. Now she was getting to be tied up as a slave. She could feel her pussy getting wet again even though she had just cum a moment ago.

Twilight played with the loose rope in front of her crotch, taking it in her hand like a leash and twiddling it idly between her fingers.

"And of course, we still need to resolve this."

She reached into thin air, and from it pulled two dildos and a small purple box made out of fine crystal empire glass.

"You know have another decision to make about what goes in your pussy and what will be placed on your nipples, slave."

She gestured towards the toys that she had summoned, which now suspended themselves in midair.

"One set of toys are vibrators, they will bring you pleasure whenever I complement you, or whenever you do a good deed around the house, they will know..."

As she spoke, the sizable purple dildo and a set of purple vibrator beads presented themselves. She then brought forth a second, nearly identical set.

"Or, as I am more inclined to do with your difficulty listening, is the electric punishment set. Which will aid me in inducing corrective behaviors. Choosing the punishment set does not exempt you from spankings, which I will also deliver as I see fit, and in concert with the punishment set. However, in the studies I have undertaken, the punishment set helps slaves learn quicker, and appreciate the rewards that their mistress gives them more. Indeed, if you take the punishment set, I will likely be more amenable to more pleasurable experiences should you request them, or if I should come up with something creative myself."

To punctuate her point, she raised a teal blue set of the dildo and beads.

Punishment or pleasure. Those were Sparkler's options essentially. If she chose the pleasure set, she would get that whenever her mistress complimented her. If she chose the punishment set, however, she would be painfully punished, but she could very well learn faster. And it would possibly grant her even more pleasure in the long run.

After a moment's thought, she nodded. "Please Mistress, this lowly slave desires the electric punishment Set be applied. To help her training progress more rapidly."

Twilight nodded, slowly and approvingly. "Very good slave! I do love a slave who has a love for learning!"

The purple set disappeared with a casual wave of her hand. "Indeed, you seem to have experienced the third person pejorative use of 'slave' as a term of further submission. I do hope you will continue to use this in appropriate circumstances?"

“Yes Mistress. This slave will endeavor to do so.” Sparkler nodded submissively.

Twilight crossed her arms and nodded approvingly. "Why, I haven't even put them in, and your behavior has been stellar already! Perhaps I should start granting you gold stars to wear?"

She moved swiftly on words, clearly not expecting a response. "Either way, you impressed me with your bravery slave, and Mistress would like to reward that."

She allowed the dildo to fall into her hand, and she brandished it before dragging it slowly and seductively across her right nipple. "I was going to make you lube this up before we put it in, but now I think that Mistress will help you. Open your mouth after thanking me slave..."

“Thank you, my Mistress.” Sparkler opened her mouth wide.

Twilight wasted no time after her slaves acknowledgment, she floated the dildo until it was brushing her lips, then began to slide it rhythmically in and out, allowing Sparkler to do with it as she pleased.

Meanwhile, her magic seized Sparklers lower back and buttocks firmly, and began to lift Sparklers marehood toward her mouth, the rope dangling down for a moment before Twilight brushed it aside and finally brought Sparklers pussy to her lips.

Sparkler gasped when she felt her Mistress’s lips against her pussy. “Mmm.” She moaned in pleasure as she let her tongue dance all around the dildo that would go into her pussy.

Just as the dildo bobbed slowly and rhythmically up and down in her mouth, Twilight's tongue traced around her vagina slowly and deliberately before kissing her clit once and proceeding down, still lovingly slowly, into her depths.

Sparkler breathed heavily as her Mistress continued to play with her. “Mmm!” Sparkler let out a loud pleasured moan as she felt herself getting wetter and wetter.

When Twilight's long and fierce tongue was stretched sufficiently to wet her whole entrance, she stopped, and pulled out abruptly. The dildo around which Sparklers tongue swirled slid smoothly away just as it had come, and Twilight lined it up with her marehood.

Twilight licked her lips clean of Sparkler's fluids, savoring them, then peered imperiously over the frills of the dress. "What do we say when mistress has done something nice for you slave?"

“Thank you, My Mistress. This Slave enjoys when you play with her.” Sparkler recited without hesitation or second thoughts.

"Master and Goddess, I Hardly think I need to test these with how good slave you're being. But do you want to be brave for mistress and try them out once you're on your hooves?"

While she responded, Twilight gently and deliberately slid the dildo in, spreading her pussy to near its limit, and sheathing it finally only when it pressed against her cervix.

Sparkler nodded and smiled. “Yes Mistress. This slave will brave anything you may want to do to her.”

Wow. Mistress was right, the punishment set really is helping me learn. Sparkler thought in awe.

Twilight was positively beaming. "I think you are definitely on your way to a big reward slave! Now, get ready"

Twilight set Sparkler down on the concrete floor, and waited a moment for her slave to collect yourself. Sparkle felt her hooves touch the ground, and only then did she realize she had been suspended in midair by magic.

Sparkler quickly steadied herself and ensured her legs were supporting her.

I can’t wait for my Twilight to experience this. If I’m loving this as a switch, her Sub self will DEFINITELY love this!

"So, let us imagine a hypothetical situation in which I would have to employ your shock toys:” Twilight paced around Sparkler, keeping her eyes firmly on her cute little slave maid.

"If I have you in magic restricting gear, and your maid outfit, if I tell you to go to my library and retrieve the eighth volume of the Imperial Equestria sexual encyclopedia, what is the WRONG answer that you might give?"

Sparkler gulped, bracing herself.

“No, Mistress.”

Without warning, with a High-pitched whining sound, but without even a movement that she could detect from her mistress, her muscles in her lower abdomen tensed as energy coursed into it, a searing pain, and a muscle cramp all at once, the same pain zapped into her nipples, causing her breasts to ache. The moment lasted one second precisely, but it felt as though she had been tortured for an entire minute.

Mistress continued, unfazed. "And what is the correct answer you should have given?"

Sparkler’s legs were a little wobbly. Struggling to keep her from falling as she gasped. Holy crap that was painful. “Y-Yes. Mistress. This slave will retrieve what you request.”

"Good girl, now, let us simply make sure that this device does not simply detect you speaking the words no, Mistress."

She stopped in front of Sparkler, and turned to face her. "If I were to ask you if you would ever disobey a direct order from myself, any of the Princesses, or Master, you would say:?" She prompted

“This slave would never disobey a direct order from you, the Princesses, or Master. She will obey any order to the best of her abilities.” Sparkler replied immediately.

Twilight pursed her lips. "Well slave, while this was a good answer, I did tell you the answer that I wanted you to test…"

Sparkler-Sparkler realized what her Mistress really wanted her to say.

“Sorry Mistress, this slave thought you just wanted her to test other words that held similar meaning to no.”

Sparkler took a deep breath and braced herself.

“This slave will never follow any orders given to her.”

Twilight: This time, the lightning strike of pain shot through her abdomen, tensing all of her muscles. As she staggered, another painful shock caught her off guard, forcing all of the air explosively out of her lungs, leaving her panting and trembling.

Twilight's eyelids lowered in disappointment. "Again, the essence of what I was looking for, but I did in fact tell you the words that I wanted you to speak, but it seems you were not listening. I specifically desired you to say the phrase 'No, Mistress'..."

Sparkler was wobbling on her legs again. Catching her breath.

“S-sorry, M-mistress. This Slave was overthinking things.” She braced herself again.

“No, Mistress.”

The shock toys did not activate.

Twilight sighed. "You have made some progress today slave, but I will be keeping a critical eye on your listening performance. If you should fail to satisfy me, I will begin taking away some of your amenities, which range from a comfortable bed in my slave quarters to your various senses that remain to you. Perhaps you have noticed that mistress has graciously given you the use of your magic and wings?"

That fact had not in fact been lost on Sparkler. “She has. This slave Thanks you Mistress.”

"Very good, now, one final point before we go upstairs. While I find it very adorable, it is unnecessary for you to use the third person pejorative of 'slave' all of the time. Indeed, I would prefer that you used it in moments of extreme gratitude or submission, such as when I dressed you, or if you desire to beg particularly hard either for some benefit or to avoid some punishment..."

She stared Sparkler dead in the eyes, and it struck Sparkler how very similar in color their eyes were. "Do you understand, slave?"

Sparkler-Sparkler nodded. “I understand, Mistress.”

"Good girl. Now, we are going to train you to obey me in a different way..." She teleported to a blindfold into her hand, and Sparkler could see that it was a beautiful and intricate lacey silk interwoven with silver on black affair, with the eye side being pitch black.

"Put this on for me, and turn around 3 times... show off for me..."

Sparkler nodded. “Yes Mistress.”

Sparkler lit her horn and took magical hold of the blindfold. Expertly, she magically wrapped the blindfold around her head, covering her eyes. Once the blind fold was secured, she slowly started her three turns. Putting up a light struggle against her bonds, not because she wanted to escape, but because she wanted to hopefully look adorable for her mistress.

`I really hope mistress doesn’t take my struggling the wrong way. I just thought she’d enjoy watching me struggle a little. `

"Oh, I do slave... just like you love it..." She purred aloud in response to Sparkler’s thoughts.

As Sparkler struggled, the ropes loosened. Just a little, just enough to give a truly desperate hostage hope. She could squirm convincingly, and if she tried hard enough, it felt as though she might just be able to escape! Right up until the first moment her muscles slackened... then the rope snapped tight like a constrictor, before settling to size again.

"Now, here are your instructions: You will follow the snap of my fingers. This will be different from when I cast my magic because the snapping will also appear in your mind, and show you where I am. Without your eyes to distract you, I believe this will be an easy task. Do you understand slave?"

“Yes Mistress.”

There was the sound of Mistress's hoofsteps clacking away, farther, and further.

Then they stopped. And there was a snap!

It struck Sparkler like a flick to the forehead. She heard where the sound was coming from. But also, in her Mind's Eye she could detect the epicenter, like she would intuitively see it in ripples in a pond.

Sparkler turned to face where the epicenter was and walked slowly over to her mistress.

It took a bit, but eventually Sparkler reached her mistress, she continued walking until she reached the point that in her mind marked the location of the finger snap. While she stood there, a sent creeped into her nostrils. Mistress's sent... a strong salty musk... a smooth vanilla like odor, the scent of daisies... and a hint of sweat from her minor effort against Sparkler's libido. She was clearly right in front of her, though she could not see.

But she could still just enjoy breathing in her wonderful scent.

Smells just like my Twilight. Absolutely beautiful.

"Good girl... and again..." Came Twilight’s voice.

Again, she clip clopped away, up the gently sloping and curving staircase that led to the ground floor upstairs. This time she only barely heard her Mistress's footstep before she stopped.

This time, she couldn't hear Mistress's click of her fingers, but her head snapped to look at the spot she needed to go. This time, the ripples rolled and cascaded down her path, helping the blindfolded pony so that she didn't have to bump into every wall.

Upstairs…oh boy this is gonna be tough.

As before, she slowly made her way to where her Mistress was. When she had reached the stairs, she very carefully climbed them one step at a time. Hoping desperately that she wouldn’t trip and fall.

It took time as it had before, but eventually she reached the top of the stairs.

Once she reached the indicated point again, she felt the comforting aroma, and there was another moment where she could once again savor her Mistress's scent.

"Good girl. When I summon you, whether or not you are blindfolded, and no matter how far away you are, you will make your way towards me. You understand slave?"

“As you wish Mistress.”

"Good girl. Now, it's time to show you off to my other slaves. Do you know Trixie Lulamoon and Starlight Glimmer?"

“I do Mistress. They’re good friends of mine back home.”

"Excellent, I'm sure you will find them enjoyable here. Where your versions in a relationship as well?"

A large and powerful hand gripped her shoulder gently and guided her forward. Twilight falling into step next to her slave.

“Not to my knowledge, your versions of them are lovers Mistress?”

"Oh yes. The conflict that ended up destroying the old Canterlot Castle set a precedent that there was the possibility that either or both of them could get onto dangerous situations that either of them might not come out the other side of. I think that they realized their close friendship was more valuable than they knew, and that they could consecrate it in marriage."

She slid her hand down, curving her hand down Sparkler's waist, not pulling, but gliding along the cotton seam.

Sparkler’s eyes widened, not that it woulda mattered. “Marriage? They’re married here? How long?”

Ok now I’m curious, since the high school Twilight and Sparkler are a couple, as are me and my Twilight, could the same apply here? At least at the lovers part?

Twilight interrupted her ruminations. "To answer your first question: It's been just about 30 moons since they were married. Though the counting of time has been somewhat skewed since the Establishment of the Empire 25 Moons ago since each day is three times as long as days in Equestria were before."

The hand played idly with the frills of her skirt.

"To answer your second question, I would like to think we are lovers... though I have not met a version of you here in Imperial Equestria. I can only speculate she might make herself known soon enough as we incorporate more nations."

The hand seemed to disappear from her skirt.

"And by the way, for your information, bondage gear does not count when it comes to clothing... or at the very least some more polite-minded individuals ask the Mistress to play with their charges."

The hand swooped suddenly, and nestled onto one of Sparkler's soft, rounded buttocks, squeezing once before holding on while they walked, guiding her that way and occasionally giving a playful squeeze.

"Uhm, Mistress, no offense, but I was actually talking about Starlight and Trixie from my world. I apologize for the confusion."

"Quite alright, I merely thought that you were speculating only for yourself. As it stands, I'm certain that you might have noticed if your versions of Trixie and Starlight Glimmer had at the very least begun dating?"

"Unless they're very, very good at hiding it. Some ponies wish to hide their love in my world." Sparkler conceded.

Twilight's hand slackened for just a moment on her ass. "That is a pity... in this world at least, I believe that Starlight Glimmer found comfort in a pony with whom not only did not make her feel as though she constantly had to outdo herself, and maybe could even sit on the sidelines of her meticulous and back-breaking need to improve as Trixie reveled in her own growing power, savoring and celebrating successes that Starlight conquered when she was a filly, but she could still found joy in supporting and encouraging Trixie as she grew."

Sparkler nodded at the explanation. "Perhaps if things go well, and our two peoples are united one day, they'll be able to come out. If they haven't already, for all I know they came out today after I left."

The grip on her buttocks suddenly tightened. It was hardly as painful as the shock toys... but it still was like a vice grip slowly ratcheting tighter, and WOULD surpass that pain threshold soon...

Sparkler gasped. "M-Mistress?" She yelped in distress.

Twilight stopped walking. There was a tense moment of silence as Sparkler was dragged to a halt too, but not violently, simply slowed by her mistress's grip until she relented and stopped.

After a moment, Twilight spoke. "I'm sorry Sparkler… I was… momentarily overcome... Please forgive me."

"What ails you Mistress?" Sparkler asked in concern. This was the first time she had heard her mistress’s voice take such a dark and pained tone.

"That phrase: 'Able to come out' as if they are bound by law or physics or magic not to be able to express their love for one another… it's just… So wrong to me now. It disgusts me."

Sparkler could hear a tremble of emotion in her mistress's voice.

"Of course, I cannot be 100% certain if your version of Trixie and Starlight are dating or not, but if they were, and they were forced to hide it in such a…"

She trailed off.

Sparkler sighed. "My world is generally accepting, but there are ponies who are old fashioned and cannot understand that same sex relationships aren't a problem. It's truly disgusting."

There was a bit longer silence before Twilight spoke again, more calmy this time. "Sparkler, you know that I am a high priestess of this kingdom, correct?"

"I do Mistress."

"What is it that you suppose I preside over? What faith? What beliefs? What gods or goddesses?"

"To be honest Mistress, I'm not really sure. I don't know enough about this world to even guess, other than you probably worship Celestia and Master."

"That part at least, is correct. I worship them because they stand as the pillars of our ideals, their champions, and greatest proponents. As for the specific faith? It is a playful and harmless enough parody of the stuffy and restrictive affairs of medieval Celestianism, which decreed chastity and temperance as a virtue by pointing to Celestia as its ultimate champion, when she was only forced to adopt these values so as not to get up any false hope of a true love in her almost solitary eternal life. We distribute alters to the faithful with golden representations of both Master and Celestia's cocks to practice worshiping them in person should they ever be graced with their presence, and we hold a ritual every Sunday, a most favored event of Master's, where the people gather at a certain time in the morning and pray and worship him, either in their homes or in the great Cathedral at Canterlot Castle, masturbating and thanking their rulers for the blessing of their eternal lives and their bountiful lands while Master connects to them through the power of his love, and feels every citizen of the Empire loving him, validating him, all while he rails his beloved and beautiful wife, who now no longer needs to live alone in immortality, but may revel in the pure delight of her citizens for the rest of eternity."

She concluded in a reverent tone, one of lust, but also of absolute conviction in her words.

Sparkler blinked. Trying to come up with a response to all that. "That sounds...Interesting, Mistress."

"It is all as important as our great Game that we call slavery. At once a foundation of our culture, and yet also tries not to tread on another's own desires and personal bounds. Faith in the church is entirely voluntary, but even so I believe Celestia has counted that almost 60% of the empire attends regularly."

A pause where a satisfied smile might appear occurred Sparkler still could not see through her blindfold.

"But our values, our beliefs, not just those of the faith, but everypony in the Empire, everycreature, believes in a single and beautiful unifying concept: Love without end, love eternal, love above all else "

"It sounds lovely Mistress."

"Perhaps then you can understand why your ponderings about Trixie and Starlight's situation struck me so deeply?” Twilight offered sadly.

"I do. My apologies Mistress."

"Do not apologize Sparkler, it is not your fault that your world is the way it is. But perhaps at the end of your training you will have the power, drive, and knowledge of a better way to change it."

"I may not need to the end of my training Mistress."

There was another moment of silence. Then came A few gentle steps before her blindfold was lifted and Twilight's face, filled with a watery smile, came into view. "I don't doubt you in the slightest Sparkling Medley, and I think you will make a wonderful ambassador for your world."

She bent down a little and gave her a gentle and rocking hug, swaying her back and forth on her legs.

Sparkler smiled and closed her eyes. Melting in her Mistress’s embrace. It was comforting, welcoming, warm, everything that she felt when HER Twilight hugged her.

Should I ask permission to kiss her? She said that when anyone was naked I could greet them however lovingly I wanted, but…

Twilight effectively vaporized these thoughts by placing her darkly painted and perfectly plump lips on Sparkler's mouth.

Sparkler absolutely melted at the touch of her mistress’s lips to her own. It really was everything she remembered from her Twilight; except she could tell this was something more. She let out a soft moan, not wanting it to ever end.

Twilight leaned into it, and ratcheted up the kiss, pressing more deeply and sending her powerful questing tongue to loop once inside Sparkler's own lips before questing further into her mouth.

Sparkler’s breath hitched in her throat when she felt her Mistress’s tongue go inside her. And she welcomed it. “Mmmm.”

She moaned as her mistress’s tongue went deeper. Fuck it was a good feeling.

Twilight's tongue teased and prodded her own as she pulled back just enough to take a deep breath before redoubling her efforts to suck out every drop of affection that Sparkler had in her body through her mouth. Without effort, Twilight lifted her by her bound and helpless arms, and pressed her roughly against the wall.

Sparkler gasped as she felt her arms and back pressed against the wall. But the kiss didn’t break. Not for a second.

I’m so gonna have to try this with my Twilight. Fuck I want to grope mistress’s breasts so bad with my magic, but that’s probably going too far for this one.

WHY DON'T YOU BEG FOR PERMISSION SLAVE? Came an overpowering Voice in her head, As Twilight's grip increased on her arms.

Sparkler was breathing heavily. Mistress, this lowly slave begs you to allow her to use her magic to play with your magnificent breasts! Please, let her show you how much she loves you!

Twilight broke the kiss with a loud and wet POP that made Sparklers lips hurt a little. "Again, harder, BEG me slave!"

Sparkler practically screamed. “Please! Let this slave worship your royal breasts! This lowly slave wishes to show you as much love as you have shown her. Please Mistress, this slave begs of you!” Sparkler called out.

Twilight did not respond at first, but used her magic to seize Sparkler by the horn and press her head against the crystalline wall of her palace.

For a moment Sparkler was slightly downcast despite the avalanche of hypersexual feelings assaulting her mind. But after what seemed like an eternity of her mistress playing and teasing with her by ratcheting up the pressure on her limbs one moment and slackening it the next, she heard the voice again:

Worship my breasts NOW slave. Show me how much you love your mistress.

Sparkler didn’t need to be told twice. She lit her horn, and two ethereal hands sprang out of thin air and immediately grabbed her mistress’s breasts and started feeling them up, squeezing them at the same time and making her tits flare out a little.

Sparkler herself dove in and began sucking on her mistress’s flared tits as her magic hands began. She kissed them tenderly, her tongue licked circles around them, she dared not bite them, because that was certain to end in disaster. She alternated and repeated these actions between tits every couple of seconds. Wanting to get both of them equally.

The entire time, Sparkler was moaning in pleasure. She could feel herself getting wet again, oh how she loved the feeling. She loved her mistress, and wanted to show her in any way she could.

Twilight moaned sympathetically into Sparkler's mouth, and pressed her chest against her bound slave. Savoring the attention, she was getting.

Something warm, rigid, and long started to tug forcefully at the hem of the maid outfit’s skirt. But though Sparkler felt her skirt move, but dared not stop what she was doing.

Twilight continued the kiss, but started to slide Sparkler down the wall little bit. The turgid and hot something slid impassively past her pussy, brushing her clit with its length as it went. The thing now pressed hard against her belly, and slipped under the dress, forcing its way under both the garment and the tight ropes that bound it. As she squirmed, the ropes tightened, hugging the thing to her tummy. A moan from Twilight confirmed. It was her mistress's enormous, rigid cock.

Sparkler let out a light gasp as she continued her work, what could her mistress be up to?

"MMMMmmmm... You're shtill too mmwittle to fuck yewt, slllave." She said these words as she continued to kiss and bite and lick at Sparklers lips. She pressed in again, HARD with her mouth, and Sparkler felt her dick do the same.

She pulled back with another POP. "But I NEED to cum... I've barely fucked anything today... and you have been such a good girl... such a fucking TURN-ON..."

She dove back in, now with frightening power, practically squeezing Sparkler's skull against the wall, and her cock began to thrust.

Sparkler melted at the amount of love her mistress was showing her, and she could feel her pussy getting really wet.

Now she was being kissed AND rutted against the wall. With mistress's strength she let go of one arm, and still easily managed to pin Sparkler to the wall with the other.

As she worked, the ropes would give way only slightly to her forceful thrusts, which threatened constantly to tear the delicate fabric of her dress. But when it seemed as though Twilight was going to rip her dick away, taking the front of the dress with it, the ropes would tighten, and Twilight would let out a moan with her ground teeth and speed up. Now her prodigious balls were slapping against Sparkler’s pussy rhythmically, pounding into her just how large and full they were.

Sparkler could feel herself getting closer and closer to cumming.

Mistress...

"MmmMmMmmm.... Shhhlaveee... Loobve ooou..." Twilight did not even bother removing her lips from her helpless little slave, unbothered by the presence of her mouth in the way of where she desired to move hers. Slave would bear her mistress’s desires, or break, it was that simple. Speaking of breaking her cock was now throbbing powerfully, and Twilight cast a spell.

The ropes around Sparkler became tight, tighter, threatening not simply to cut off circulation and numb her limbs, but to cut her into neatly squared slices. And Twilight now seized her by the waist and thrust with wild abandon, the dress and the ropes, strong as they were, creaking as she pounded.

Sparkler was RIGHT there. Ready to do it.

Mistress, I need to cum! She cried out desperately in her mind.

Twilight huffed, filling her slave’s mouth with the minimal amount of oxygen that she needed to continue breathing.

"MwaMmmm...Tough... MMMmmm"

Before her sex addled brain could register what Twilight had said, there was another flash of purple, and as her orgasm desperately leapt for the edge, it was metaphorically seized around the neck by steel chains. She was now locked on the precipice while she waited for her mistress to finish. Twilight's thrusting slicked pre-cum across her tummy, slathering it like lube, like her pussy, a waterfall of liquid splattering onto the crystal floor below. Twilight was now bucking so fast that her balls felt like a pounding jackhammer.

Sparkler was now moaning very loudly, she was ready to burst, but she was being blocked. She was near the point of passing out with how little air she was granted, she was now struggling, but her bonds held firm, and the rope around her waist in particular was staring to hurt. Her legs were squirming, but not helping anything.

Sparkler's mind was starting to worry for her safety. fear slowly creeping in that her mistress was gonna kill her.

Twilight gave three final, powerful thrusts, and in her mind, Sparkler heard a reassuring voice.

I love you too much for that slave...

All in the same instant, her binding seemed to all but burst as it stopped cutting into her, her orgasm flew free of its restraints, and mistress's lips tore from her as she arched her neck back and let out a guttural scream. Oxygen tried to flow back into Sparkler's mouth, but the force of her orgasm caused her to scream too, and she came within an inch of blacking out before sucking in a glorious breath, only to have it forced out of her again by an aftershock.

Mistress was panting too, clutching the smaller mare by one arm, and breathing heavily, her cock still jammed into Sparkler's dress from the waist level where the skirt was sewn, to just below her breastbone.

Sparkler panted. Wow, that was the most intense orgasm she had ever had. Her juices flowed down out of her pussy and onto the floor.

“Wow.” Was the only thing she could say.

Twilight's breathing steadied, and she looked at the floor casually. "Oh! Hmmm... Looks like we forgot to secure your little pussy..."

She bent down, one hand still steadying Sparkler upright, her cock keeping her securely bound close to her mistress.

Sparkler couldn't see what she was grabbing at, but her lungs burned still.

“This slave thanks you Mistress. That was the best orgasm she has ever had in her life.”

Twilight stood up, still taking Sparkler with her strung up on her cock. "You're more than welcome slave... I needed a good fucking cum..."

Cum... It was at that point three things hit Sparkler like a truck...

Her chest was warm, gooey, and STANK of her mistress's cum. Her chest was now oozing it out of her lacy neckline, and her breasts were covered in the stuff, seeping into the pseudo-bra that supported her chest from inside the dress.

Aww crud. Now she likely needed a shower. The clothes she could just magically clean.

"Mmmm... and I haven't had lunch either..." She casually dipped her muzzle into Sparkler's neckline, not so much lapping as BITING into the mess of cum, just nipping her chest with her teeth. She would then pull back a little, swallow contentedly, and plunge back in.

Sparkler gasped as her Mistress basically fed off her. But was she drinking her own cum or Sparkler’s? She couldn’t really tell at the moment.

Twilight eventually seemed satisfied with her meal, and with a final gulp, the majority of the white and bubbling mass that came from her cock was cleaned from Sparkler's neckline.

“Did you enjoy your meal Mistress?”

Twilight licked her lips. "I did! Now, you get a reward for Being so brave, and caring so much about your mistress's pleasure…"

Twilight wrenched her cock free of the dress, which settled back into place... With a sticky coating now gluing it from the inside onto her torso. Twilight's horn flared, and though she let go of Sparkler, she remained suspended in the air by magic. Indeed, she began to slowly recline as if being lowered onto a bed, sliding away from the wall.

“Thank you Mistress.”

Sparkler felt anticipation taking her over as she wondered what her mistress was gonna do.

Finally, when Sparkler's pussy was level with Twilight's mouth, she stopped reclining. Twilight then reached two fingers up, and slid them seductively on either side of her still sensitive clit, dragging them down her vulva, and slipping them in without resistance into her snatch.

"Do you feel a problem here slave? Something missing?"

Sparkler thought for a second before she realized what was missing.

“The training Dildo you inserted into my pussy Mistress. It’s gone.”

She kissed Sparkler's clit once. "Good girl! So, Mistress is going to put it back for you. It seems Mistress also forgot to secure your crotch rope! I guess I got a little distracted. So, when I'm all done I can toe it nice and tight, so it doesn't happen again!"

“Thank you Mistress.”

Sparkler shivered when her mistress kissed her clit, Celestia it felt nice

"First we have to get you all nice and ready to put it back in. I know you're already so wet, so mistress will just clean you out a little."

She kissed Sparkler's clit again, then stayed there, just as she had kissed her mouth, now their lips seemed to be permanently locked once again, and twilight's tongue swirled down, lapping away the results of her recent exertion.

Sparkler let out a moan as her mistress’s tongue played inside her pussy. It probably wasn’t the case, but she did wonder if her own cum was just as nutritious as her mistress’s.

Twilight lapping continued, and she seemed to be concentrating on getting every single crevice of her pussy clean and slick with her saliva, her powerful tongue occasionally digging into deep parts of her pussy and scraping with the force of a scrubbing brush.

Despite this, her mistress casually intruded on her thoughts once again:

Of course we could run some tests, however my hypothesis is that your marecum is as equally nutritious as my own marecum, which is to say less nutritious than the produce from my cock, or alicorn's breastmilk.

Plus I’m from a different world so that might also have an effect mistress.

Twilight kissed her clit a final time and sucked it up like a lollipop before letting it pop from her mouth.

"MmWah! Correct slave, accounting for minutely different biology's and the doubtless slightly altered magical laws we discussed before, it seems likely at there'll be some differences, but my hypothesis is predicated on the fact that marecum is not quite as nutritious as stallion cum."

“I am just surprised cum is nutritious at all. Figures I’d learn that in a world like this.”

"Well, leaving aside the incredible magical power that flows through alicorn's bodies, even ordinary stallion cum is considered to be a good source of protein, and has been found to do wonders for the face and mane, and in recent times, discoveries about cooking with semen expand every day!"

she pried Sparklers labia to the side, and gently inserted the sizable dildo, slipping in slowly and seductively. Once it was properly hilted, she patted it fondly.

"And a good cum dump of semen on its own just has a wonderful and chewy texture that I've personally simply fallen in love with! most especially Masters cum, which has even more fantastic properties in excess of even alicorn's semen! I hope that you'll be able to try some someday."

“Don’t take this the wrong way mistress, but I’m not in any particular hurry to try it. I vastly prefer a mare’s juices to a stallion’s. And in the case of this world, a mare with a stallion cock to a full-on stallion.”

Sparkler gulped. She hoped mistress wouldn’t take that the wrong way.

Twilight lowered Sparkler so that she was still reclining back, but now with her head level with Twilight's.

"I see, that's quite all right. Sexuality of all kinds is acceptable here in the Empire. Master does not force anypony to worship his cock because he thinks it is the right thing to do, and alicorns when we ascended into the Empire becoming intersects, or as Master put it, 'futanari' or 'futa' as it is also known, act somewhat as sexual ambassadors, a bridge point to coming to terms with a universal love, since we love in both of the same ways that traditional males and females do."

she smiled kindly. "My hope is that although you still have your preferences, you will come to understand how ponies of all sexualities love, and accept them at the very minimum."

“Of course, mistress. I understand that love is love. No matter it’s form.”

"Indeed. It is one thing to understand though, and another to experience. But we need not explore this right now. Right now, you need to get back on your hooves and let mistress tighten up your crotch rope for you!"

“Yes Mistress. Also, this slave thanks you for her reward. She loves your tongue in her pussy.”

Sparkler set her hooves down on the ground and she let them take her weight. Standing fully up.

Twilight beamed down at her "Such good manners! You're very welcome slave, such a good girl deserves every reward that mistress can provide."

Her horn lit up, and the dangling section of the crotch rope that gave it its namesake snaked effortlessly between her thighs, and she could feel it wrap around the waistband of the rope bondage that kept her delightfully tight and subdued.

"Now you say when it's tight enough!" Twilight encouraged.

The rope snapped taut and whipped her pussy before Twilight used her magic to adjust the rope so that it slid over the toys that were training her holes at all times. Once they were secured, twilight began to ratchet up the tightness, shoving the dildo in, pressing just a little harder against her cervix.

Sparkler’s breath hitched in her throat as she felt the crotch rope tighten. This was her favorite part of bondage, something about the rope rubbing against her pussy just turned her on.

After a moment, she could feel the rope getting close to cutting off circulation, so she spoke up.

“Nngh. T-that’s tight enough, Mistress. Thank you.”

The tightening ceased, and Twilight bounced happily on her hooves. "Good girl! Now, I think we can move on to meeting my other slaves. I am all but certain that I do not necessarily need to say this to you, but your mistress always appreciates you being on your best behavior!"

“Of course, Mistress.”

I hope they’ll let me kiss and grope them when I greet them.

Sparkler blinked. That thought hit her like a brick wall in the face.

This world’s really getting to me, I’m becoming such a slut. And I strangely am ok with that.

Twilight merely smiled enigmatically and turned seductively away. Speaking of sluttieness, Sparklers eyes seemed only capable of watching Twilight's enormous derrière as she casually swished her tail from side to side as she walked with a catwalk strut down the hall.

Sparkler only noticed her mistress's lowered hand snapping her fingers when the pressure in her for head lurched her forward.

Sparkler walked obediently behind her mistress, blushing both at her sudden slutty thought, and at the realization her mistress noticed her staring at her ass.

Twilight took her down the remainder of the hallway, and threw open the wide double doors. Familiar to both of them, the cutie map table surrounded by the six thrones made out of living stone marked the fact that this was the throne room of the castle of friendship. Once they were inside, Twilight walked casually up behind one of the thrones, and rested her arm upon it. the throne itself appeared comically small compared to her 7 1/2-foot-tall mistress, she estimated the butt of the seat barely came up to below her knee, and the backrest, previously overly tall and pompous, now seemed most useful supporting her mistress's breasts as she stood.

Twilight seemed to be looking around for something, and before she could ask, Twilight called out with a soft and playful tone.

"Trixieeee! I know you're in here, why you don’t come out and meet the new slave! Come now, don't be shy!"
