Twilight giggled madly as the group of foals before her turned around, only to be confronted by none other than Nightmare Moon.

“What’s this?!” she shouted, her fangs bared in a maniacal grin. “Look at you! So many delicious morsels, so little time!” She spread her wings and cackled wickedly as the colts and fillies shrieked, cantering past her in a panic, even as a few screams were broken by laughter.

The dark queen turned to watch them as they went, wings still swept wide, and shouted, “Run if you wish, but you’ll never escape me forever!”

Bringing a hoof to her mouth, Twilight attempted to stifle her laughter. “I don’t know, Nightmare Moon. I think all that candy you’ve been eating is slowing you down.”

“That truly never gets old for you, does it?” grumbled the dark queen, turning to reveal a deadpan that was nothing short of spectacular.

Twilight shook her head. “Nope.”

Moon smiled wryly before shrugging. “Fair enough. I suppose this never gets old for me.” A blinding light ensconced the imposing alicorn, fading after a few seconds to reveal ex-princess Luna. “Was that the last group?”

Twilight nodded. “Yes. Everypony should be gathered in the palace square. The Nightmare Night Ceremony is ready for you to conclude whenever you’re ready.”

“Whenever I’m ready, is it?” replied Luna, raising a playful eyebrow. “In that case, I believe I’ll carry on until it’s time to raise the sun.” Before Twilight could respond, she raised a hoof, smirking. “But of course, I wouldn’t wish to disrupt any plans that you and your wife may or may not have.”

Twilight’s eyes widened as her cheeks ignited crimson. “We, um. . . You know about that, huh?” She forced a grin through the embarrassment. “I’m guessing my dreams must have shown you some things. . .”

“One might say that,” she declared slyly. “Dear Rarity reached out to me some time back and requested that I prevent you from remembering any dreams that might be tied to her plans for this evening. She was quite dedicated to ensuring that the surprise remained a surprise.”

The lunar alicorn bit her lip playfully. “I admit that I may have enjoyed a few, but ultimately chose to respect your privacy as a couple, and so only have broad ideas of what you may be in store for. Either way,” she bowed slightly to the princess, “it would ill become me to keep either of you waiting. I’d best see to the ceremony’s end.”

Still flustered, Twilight returned the bow. “I-I suppose so. Er, happy Nightmare Night, Luna. As always, thank you for coming here and lending your particular brand of fun to the celebration!”

“And happy Nightmare Night to you, Twilight,” she responded, spreading her wings wide. “Thank you for allowing me to participate. It never ceases to be fun delighting and frightening others.” With that, she rose into the air and banked toward the castle courtyard. “Fare thee well, Princess Twilight! Enjoy your night! Sister and I will see you two weeks hence for our usual tea time!”

“Goodbye, Luna!” she shouted after her. “I’ll see you then!” She watched the former ruler disappear behind a turret before turning back toward the palace’s main door. Butterflies began to gather in her stomach as she lit her horn and pulled it open. It was beginning to sink in that, finally, after almost two months of wondering, she’d finally find out what Rarity had in store for her.

For the most part, she was excited that she’d finally learn the secret. She knew that, in the beginning, she could usually remember at least some details of what happened when Rarity had guided her into trance, but it hadn’t taken more than a couple weeks before even those vague impressions faded. She only knew for sure that, whenever she woke up, she felt wonderful, and more often than not, very wet and deeply satisfied.

There were, however, a few niggling slivers of doubt. Now that it loomed before her, Rarity’s warnings about what the Trick could entail seemed a lot more serious. Additionally, the gaps in her memory from each session, while expected, were also disconcerting, and more than once she’d wondered why she wasn’t more curious about her hypnotic escapades. She’d speculated a few times, but each time had found herself suddenly distracted, and hadn’t noticed that her mind had moved on until later. It was always possible that Rarity had given her a suggestion not to think about it, but such a command seemed excessive, even for the perfectionistic unicorn.

Her thoughts carried her into the castle and along the route to her chambers, each step sending another jitter of anticipation down her spine. In what felt like no time at all, she stood outside her chamber doors. She took a deep breath, hoping to calm both the tension in her legs and the heat in her nethers, and lit her horn, pushing the doors open.

“Wow.”

Twilight hadn’t expected much that didn’t come from her hypno-enhanced imagination, but her wife really had gone the extra mile to make the whole thing intimate. There were rose-petals everywhere, and the entire room basked in the warm light of dozens of candles. The scents of jasmine and sandalwood colored the air, along with a subtle, musty hint of old books.

For a moment, any worries Twilight felt were forgotten, replaced with warmth and gratitude for the mare who so loved her as to make the scene before her happen. If she’d worked so hard just to set the right mood, then surely she’d put even more effort into making her fantasies just as wonderful.

An especially dense layer of roses formed a path leading into the hallway. Twilight followed the trailer of fallen petals, beaming through the shivers that were beginning to tiptoe along her limbs, until she arrived in the bedroom.

Rarity lay waiting for her, stretched languidly across satin sheets. Her expression was one of some divine seductress, a mare who could tempt gods with her sensual charms and knew it. Twilight felt her heart melt and her loins burn as she stared into those eyes, and her anticipation skyrocketed as Rarity pat the bed beside her and purred, “What are you waiting for, Twilight? Join me.”

Twilight did as requested, taking in the room as she went. It had received similar treatment to the rest of her chambers, along with the addition of a few black ribbons and streamers overhead that both felt appropriate to the holiday and contrasted with the red. “Wow, Rarity,” she said as she climbed onto the bed and laid down beside her wife. “This all looks amazing.” She pressed down into a long kiss, which Rarity punctuated with a hoof on her cheek. “You didn’t have to do all this, though. I mean, won’t I mostly be living in a fantasy anyway?”

“Oh, it’s nothing,” replied the unicorn modestly. “The work for our fantasy was already done, and it’s hardly fair to you, since you don’t remember any of it. I wanted to make sure you knew that, although I was the one who wanted this, I care about you too.”

Twilight hummed in amusement before going in for another kiss. Rarity met her diagonally this time, placing a hoof on the alicorn’s jaw to encourage her forward. As the kiss deepened, Twilight felt a warm, familiar tongue against her lips, gently asking for entry. She granted it with a breathy moan.

Some meaningless measure of time passed before the two came up for air. “I never forgot you cared, Rarity,” panted the princess. “You’d never let something like that happen. Still, it’s always wonderful to see what you can do when you give it your all.” She kissed the base of her wife’s horn. “You really are amazing, honey.”

Rarity smiled graciously. “What can I say? I have a good reason to strive for amazing.” She raised a hoof as Twilight moved in for another kiss. “Before we go any further, darling, I’d like to share a more traditional treat with you.” Her horn lit, and a silver tray with two small ovals of what looked like chocolate made their way to the bed. She gave Twilight a rather smokey look as she lifted one of the candies to her lips, took it between her teeth, and raised an eyebrow in invitation.

Twilight needed no further asking, leaning down and pressing into the deepest kiss yet. The orb seemed to melt on contact, adding a bittersweet flavor and creamy accent to the pleasure of a passionate kiss. It was a moment of blissful decadence, of dancing tongues and the taste of rich chocolate blending with the more familiar flavor of her wife’s mouth.

Twilight was panting heavily by the time they separated, though Rarity seemed surprisingly composed. “Happy Nightmare Night, my love.”

The princess hummed happily as she nuzzled into the smaller mare, trying to make as much contact as physically possible. “Happy Nightmare Night.”

Rarity pressed in for a moment, favoring Twilight with a kiss on the shoulder before leaning away and twisting herself off of the bed. “Now,” she said, turning to face Twilight and looking toward the tray meaningfully. The alicorn looked down and noticed that, in the spot where the first chocolate had been, sat two small paper cards, each marked with the symbol of Nightmare Moon. “Are you ready, darling?” Her breath hitched on the last syllable. It seemed even her composure was starting to crack.

For all of her earlier trepidation, somehow Twilight did feel ready. She was still aflutter from the kisses and anticipation, but it almost felt as if she were about to exercised and had somehow stretched instantly. She nodded. “If you are.”

Rarity smiled a smile that Twilight wasn’t sure she’d ever really seen before. Certainly the unicorn could look wantonly hungry when she wanted to, but the grin gleaming on her wife’s face felt almost. . . predatory. “Then it’s time to cast the die, Twilight. Trick, or Treat?”

This was the moment. Two months of buildup, of missing memories and hypnotic suggestions had all led up to this. Twilight’s entire body tingled with nerves and arousal, and her hoof was trembling as she tentatively reached down and tapped card on her right.

Rarity panted as her horn glowed, lifting the card up toward her eyes. She stared at the paper for a brief moment before her grin went from predatory to something almost feral. She looked up at her wife as though sizing up a meal and flipped the card over, her voice and the ornate writing registering in Twilight’s mind at the same instant.

“Trick!”

All at once, the world around Twilight began to shift. Everything in sight seemed to expand or contort. Most of the candles went out, and those that didn’t suddenly blazed with a blindingly bright shade of blue. The greatest change by far, however, was Rarity herself.

The unicorn immediately began to grow, her limbs becoming limber and supple as she sprouted up taller than Twilight. Her mane billowed forth like a living thing, expanding and darkening as it began to flow in the still air. She shadows seemed to rise around her, weaving themselves across her coat like strands of umbral silk. By far the worst, though was her eyes. The warmth in them gave way to a cold that demanded obedience even as if promised untold pleasures, emanating from diamond edged, catlike pupils.

The Nightmare of Rarity’s past stared down at the shocked alicorn, her grin lazy and utterly confident. “Hello, Twilight,” she purred, her voice a sultry mockery of the original. “It’s been some time, hasn’t it?” She nodded to the alicorn’s royal finery, sat in its usual spot in the corner. “You’ve moved up in the world since the last time we spoke.” She let out a rich, musical chuckle. “That’s good. You’ll be that much more useful as the ruler of Equestria.”

Twilight’s horn blazed to life, and a dome of purple sprung up around the intruder. “What is this?!” she bellowed, springing to her hooves. “We drove you out! We helped Rarity beat you! How’d you come back?!”

The Nightmare openly laughed. “Come now, Twilight, surely a mare of your brilliance knows better than that. Our friends’ love helped Rarity grow stronger than her doubts, but those doubts didn’t simply disappear, and neither did I. All I needed was for her faith in herself to be shaken again, and the feelings inspired by this little “trick or treat” experiment did nicely.” She raised a hoof grandly. “It’s a whole new me, more powerful and beautiful than ever!”

Twilight’s horn crackled, and the entire room shook as she stomped down. “That’s enough! Let her go, now!”

Rarity tsked. “Temper, temper, Twilight. You really should work on that aggression. You wouldn’t want it clouding your head.”

Twilight’s eyes went saucer wide and she began to shake her head as an undefinable fuzzy feeling invaded her mind. Her barrier flickered and faded away, and a sputtering horn was her only reward for trying to manifest another, at least until the mental buzz destroyed her focus again.

“You. . .” she stammered, unable to so much as form a coherent sentence, “what’s. . . did. . .”

Even the Nightmare’s sympathy was haughty as she stepped forward, still half grinning. “Sorry, darling, but I’d rather not fight you. Neither of us would be happy if you managed to injure this body, and I prefer not to break my toys.” She smirked. “Break them in, on the other hoof. . .”

“What’s. . . Rarity. . . where?!”

The lithe unicorn rolled her eyes. “Ugh. That halting speech simply won’t do,” she huffed before leaning down and pressing her horn against Twilight’s. There was a spark, and an odd heaviness settled into her head. “There,” she said with an approving smirk. “Now we can talk with clear heads.”

The buzzing faded, and Twilight immediately reached for her magic. Panic jolted down her spine when it proved to slippery to grasp and shape, but not surprise. Without her magic, she had no idea how she’d get out of this. “Let Rarity go!” she demanded. “Take me instead!”

The Nightmare actually seemed a bit taken aback by her offer. She looked away, her features tight, and cleared her throat a few times. When she turned back, her grin was a bit shaky. “That’s a very sweet offer, princess. It means a great deal to her. However, I’m afraid I’ll have to decline it on the grounds that you’re already mine.”

There was a dry click as Twilight swallowed, a terrible suspicion blooming in her mind. “What’s that supposed to mean?”

Rarity raised an incredulous eyebrow. “I think you know the answer to that question, Twilight. You just don’t want to say it because it frightens you.

The princess shook her head rapidly. “But hypnosis doesn’t work like that!”

“Normally that’s true,” replied Nightmare matter of factly. “However, I’ve had nearly two months to mold you, darling. That’s hardly a normal amount of hypnosis.” Her eyes went to the ceiling and a mischievous hoof rose to her chin. “I may have also added a little of my own magic to the process.” She winked. “It just wouldn’t be me without that personal touch.”

Twilight began to hyperventilate. She couldn’t help it. She was potentially enslaved to a Nightmare that had possessed her wife. There had to be a solution, but she couldn’t see one. “I. . . we need. . . the Elements. . .but they won’t work on you!”

Rarity’s demeanor changed in an instant. Her expression cooled, and her horn lit, summoning a very familiar gem from somewhere. “Calm, Twilight,” she said, her voice low and soothing at the crystal began to sway before the alicorn’s eyes. “Calm, relaxed, peaceful. . .”

The reaction was automatic; Twilight’s body immediately sagged in relaxation. Her eyes glazed over as they locked on to the crystal, and though she fought it, she couldn’t stop a wave a calm from sweeping over her, gently pushing away her hysteria. Wide as the disconnect was between the situation and her new tranquility, she couldn’t deny that she felt better.

“I know this is a frightening situation, darling,” Rarity continued, bringing the crystal to a gently spinning stop, “but it doesn’t need to be. You can keep fighting me if you really want to, but you’ve already lost, and I promise, there’s such pleasure in store. . . if you surrender.”

A spark of defiance lit itself in the ether of Twilight’s relaxation. “No. . . You have Rarity. . . I’ll never surrender to you.”

The Nightmare chuckled under her breath. “Oh, silly Twilight, I’m helping Rarity. It benefits me, of course, but she never would have accepted her desires at all if I hadn’t pushed her. Thanks to me, she’s finally surrendered to what she truly wants.” She leaned in, her warm breath tickling Twilight’s ear before she planted a kiss just behind it, right in the spot that the alicorn loved the most. “Why not surrender with her?”

Twilight clenched her teeth, trying to push against the weight of the calm. “No. . . I won’t. Not to you.”

Rarity hummed in amusement. “Yes you will, darling. I was just hoping to make it easier, but,” she shrugged, “c’est la vie.” Her horn flickered, and the crystal zoomed off somewhere. “Now, if you’d be a good little ponyquin for me, we can get started.”

The alicorn’s eyes narrowed as an oddly comfortable numbness crept into her body. She attempted to shake her limbs out, only to find that the weren’t obeying her. Her earlier sense of panic returned quickly as she tried in vain to make her body move, the sole exception being her eyes and mouth. “What’s going on now?!”

Her captor giggled. “Oh, a little post-hypnotic suggestion I left you with. It’s just one of many, but this was one of Rarity’s favorites.” Her horn glimmered, and Twilight felt one of her wings stretching out, her muscles yielding easily to the magical touch. “She’s spent hours posing you, playing with your frozen body. She loves it. I do wish she’d let you remember it at least a few times, though,” she added as she began to walk around the frozen alicorn, seemingly admiring her. “You were always so wet by the time she was done.”

Twilight gasped as a sudden, powerful spike of pleasure lanced through her, making her entire body heat up in an instant.

“Of course, she’d end up rather wet herself by the time she was done. Toying with you like this drives her simply wild. Whenever she plays this particular game, messes follow. The floor gets wet, the pillows get wet, and oh, how the sheets get wet.”

The alicorn yelped at each use of the word, each rush of pleasure more powerful than the last. She wanted to hate what was happening. It was entirely, heinously wrong, and yet somehow it didn’t disturb her. Each surge of bliss seemed strangely familiar, and though it shouldn’t, that familiarity eased away what should have felt like a violation.

Her embarrassment as she felt a droplet of arousal began its way down her leg was still just as keen, though, especially when Nightmare’s nostrils flared and her grin widened. “See? Doesn’t that feel wonderful?” She tilted her head meaningfully. “What you’re feeling now is just a sample of the pleasure I can give you.” She walked out of sight, and soon after Twilight gasped as a hoof settled on her tingling mound. It was familiar in all the right ways. “Are you sure you don’t want to surrender?”

The word ‘surrender’ snapped Twilight back to her senses. What was she thinking? She couldn’t possibly be enjoying this. . . could she?

“No!” she shouted defiantly. “I won’t surrender anything to you!”

Nightmare chuckled richly from behind her, and Twilight whimpered as the hoof began to move in a slow, delicious circle. “Hmmm. . . I’m not convinced, Twilight. What’s more,” she began planting slow, sensual kisses along the alicorn’s rear, “I don’t think you’re convinced, either.”

Twilight bit back a moan as the hoof grazed her clit. She wasn’t sure if it was her inability to move or more hypnotic trickery at play, but she felt far more sensitive than usual. Her wife was no novice with her hooves, but she’d never made her knees weak with nothing but a little rub. She clenched her jaw. “Then you don’t know me.”

Nightmare snorted. “Of course I know you, darling. I know everything about you.” Magic chimed, and Twilight’s felt her body yield as her head was pushed down, her back arched, and her hind legs were pushed apart. “For example, I know this is the position you take when you fantasize about your brother.” Twilight’s cheeks burned red hot, but the unicorn continued. “I also know why, and I think it’s a pity.”

In spite of the situation, confusion managed to break through the chaotic tapestry of Twilight’s other emotions. “W-What? What does that-”

“Even in a fantasy, you don’t like to face him,” interrupted the unicorn, as she re-entered Twilight’s field of vision. “Even when it isn’t real, you can’t look at him, because that would make it too real, and you’re afraid of what you’d see.”

“What’s. . . What does that have to do with anything? Why even bring that up?!”

Rarity stooped down, bringing her face to Twilight’s level. She looked. . . troubled? “It’s just one more thing I think you should surrender to. Nothing’s wrong with a fantasy. You’re right, though. Forget I said it.”

Twilight blinked rapidly, her brow furrowing. Had Nightmare said something? She wasn’t sure. She screwed her eyes shut. This was no time to lose focus.

“Do you really have to leave me in this humiliating position?” she hissed.

Nightmare smirked as her eyes flickered upward. “And stop admiring those fabulous flanks of yours, darling? Or your perfectly presented, wonderfully wet marehood?” As Twilight groaned and shuddered, she let out a false sigh. “I suppose we could move on, if you really want to.”

Before Twilight could respond, she felt herself rise into the air and drift over to the bed, where she was gently placed on her back. The magic spread her wings and hind legs, tucked her forelegs to her chest, and, strangest of all, pulled a pillow under her head.

Rarity climbed up as well, looming over her, casting a shadow that seemed to sparkle. She lay sideways, letting her eyes rove over the alicorn’s frozen form. “So beautiful. . . so helpless. . .” she rolled to bring her face to Twilight’s, grinning lazily, “and all mine.”

She began kissing her way down Twilight’s body, starting with her cheek, then jaw, then down her neck. Every kiss left a pleasant, lingering burn, and Twilight found herself wishing she could squirm. The inability to move was maddening, and worse, she wasn’t completely sure she disliked it.

The feeling only intensified as Rarity continued her work, the feeling morphing into a ticklish tingle as she pressed her lips to the alicorn’s navel. Her body began to shiver again when the dark mare paused at her teats, lavishing each one with tingling kisses and gentle nips. Once again, she wanted to feel disgust, but the familiarity of the movements stopped it from happening.

Now quivering, Twilight waited helplessly as the unicorn’s full lips drifted over her lower ones. Rarity blew gently, earning a squeal, before murmuring. “My, my, Twilight. How wet you are.” She paused for the second, louder squeal, and said, “I bet somepony wants to cum, even though she hasn’t serviced me at all.” She was so close that Twilight could feel her hum. “I suppose I could indulge you. After all, I am generous. . .”

The moment the lips made contact, diamond glimmers sparkled across Twilight’s vision. The tension that had been slowly gathering through her body coiled all at once, and with the rest of her body frozen, it all went to one place.

Twilight screamed in ecstasy as the orgasm tore threw her, setting every nerve alight with pleasure. Her nether lips spasmed, and a jet of pure arousal splattered directly into the Nightmare’s face.

Twilight shook for what felt like days before the delicious tension finally subsided. As she closed her eyes, settling into the afterglow, a much beloved voice whispered in her ear.

“Good girl, Twilight,” Rarity cooed. “It feels so wonderful to let the pleasure take you. Ride it down, down, down. Let the pleasure pull you deeper and deeper into blissful submission. Sink closer and closer, helpless but happy, toward surrender. It’s so much better than resisting.”

Twilight furrowed her brow as her eyes opened. The room had shifted again. Everything seemed dreamy and insubstantial, and faint, tiny points of light had formed along the walls. The only thing that seemed solid was the unicorn’s dripping face smiling down at her. She giggled wantonly. “Somepony was certainly ready.” She rose to her hooves. “Seems we have that in common.” She turned, and Twilight’s eyes widened. Nightmare was soaked.

The dark mare looked back at her, grinning expectantly. “I gave you a taste of the pleasure in store for you. Now I think it’s time you tasted something else.”

Twilight’s eyes widened as her mouth went dry. Her nostrils flared, drinking in the scent of aroused mare. Right in front of her sat Nightmare’s pristine, glistening marehood, and she needed it.

The fact that she could move again was barely noted as she fumbled to get her hooves beneath her. The slight thrill of panic as she realized what she was doing was likewise swept aside. She was thirsty, and she was horny, and the pink peeking from within those midnight lips was just too enticing.

As she lurched forward, she suddenly found herself stopped by an aura of blue around her barrel. She struggled against it dumbly, stretching her neck forward and sticking out her tongue. She was so, so close to tasting it!

Rarity let out a sultry giggle. “Now, now, Twilight. I know you’re eager, but I never said you could have it just like that.”

Twilgiht whined, straining against the spell. “But I-”

“Lay back down, and I may reconsider. If you want to taste this pussy, it will have to be on my terms.”

The alicorn smacked her lips at the word, squirming in vain for another few seconds before groaning and throwing herself backwards.

Rarity turned, admiring the sight for a moment. “Good girl.” She stalked forward, stepping over Twilight with teasing confidence. “Now. . . how bad do you want it?”

Twilight flung her head back in frustration. “Please just let me eat you out! I need it!”

The unicorn’s smile grew strained, and she couldn’t hide the shudder that made her entire body shake. “V-Very well, darling. I’ll be generous.” Stepping forward with deliberate slowness, she moved until her sopping marehood was directly over Twilight’s head, and lowered it at an agonizing pace.

The sight of her prize within reach proved too much for Twilight. Without prompting, her hooves shot up, wrapping around the dark mare’s hips, and unceremoniously pulling those ebony petals directly onto her muzzle.

Sweet relief flooded Twilight’s body as she pushed her tongue out, driving it as deeply into the glistening snatch as it would go. She supposed the squeal from overhead was nice, too, but it paled compared to the satisfaction she felt as the musky- sweet flavor of passion filled her senses. It was like food after starving, or sleep after exhaustion. It just felt right.

The feeling only intensified as the Nightmare began to grind against her, letting her lap up even more of the flower’s divine nectar. Above her, she could hear the unicorn gasping for breath, trying to say something that must not have been important, because she couldn’t seem to get the words out. It grew higher and higher, and the grinding became erratic. Twilight opened wide, surprised that such a reward had come so fast, but too happy to care.

Nightmare Rarity cried out in ecstasy, her body seizing with pleasure as a rush of marecum met Twilight’s tongue. The alicorn licked greedily, determined to savor every last drop, which only seemed to encourage more. She felt the body above her spasm, and a hoof fell on her cheek with a desperate, “Stop-stop-stop-stop-stop!”

As quickly as it had come, Twilight’s strange thirst vanished, though the satisfaction it had brought lingered. She lay back, smiling contently at a marehood well serviced and a reward well earned.

The mare above her panted for a long moment, her face concealed by her undulating mass of mane. When eventually she brushed it aside, Twilight saw her satisfaction mirrored.

“Good girl, darling. Very good indeed.” She brushed a hoof along Twilight’s lips, which the alicorn began sucking with a hum. “You feel so wonderful right now, don’t you? Now you see what happens when you surrender.”

Twilight giggled dully, letting the hoof go with a final lick. “I. . .” she suddenly frowned, “surrender?”

Realization crashed against Twilight’s contentment like a runaway wagon. “What am I doing!” she shrieked, trying to squirm away from the Nightmare’s soaked groin. “What am I doing!” She managed to get her hooves under her, heedless of her captor’s protests, and began pulling herself loose. “Have to get the Elements! Has to be a way to-”

The gem dropped into her view, spinning slowing, glimmering in the dim light. “Calm, Twilight,” seemed to fill the whole world, and her panic drained away as surely as the tension in her muscles. “Calm.” A soothing, familiar hoof began to stroke her neck, which grew instantly heavy. “Now turn, and look into my eyes.”

Twilight’s body moved of its own accord. Those icy blue eyes stared into her, every bit as captivating as the crystal. Oddly, though, they seemed more concerned than anything. “Why are you still resisting, Twilight? As you can see, I already have you. You’re mine. Why keep fighting?”

“B-Because,” Twilight answered weakly, “I have to save Rarity from you. . . have to save Equestria from you.”

Nightmare gave her a pitying look. “Darling, you can’t even save yourself, much less Equestria. You can, however, still be with Rarity.”

Against the weight of trance, Twilight’s eyebrows managed to come together.

“Rarity surrendered to me already, Twilight. It’s why I’m here. Join her in surrender, and you can still be together.”

The alicorn shook her head sluggishly. “Can’t.”

Something glimmered behind the Nightmare’s eyes, and she grinned slightly. “Then I propose a deal, princess. I will release Rarity if you can resist surrendering with her. However,” she licked her lips, “I won’t hold back.”

Twilight did her best to glare. “Deal.”

The unicorn smirked. “Fabulous. Now,” her horn lit, and Twilight was flipped onto her back yet again. This time, however, she couldn’t help but notice that felt strangely comfortable. “Let’s finish this.”

She looked away, and for the first time Twilight noticed how drastically their surroundings had changed. The room had ceased to exist. All that remained was the bed, and an endless expanse of purple darkness and glinting gems. She blinked in surprise at the sight, and the Nightmare took advantage of her distraction by grabbing hold of her horn and pulling her muzzle directly into her marehood.

“Give in, Twilight. Give in to me. Accept you place, and surrender.”

Twilight squealed into the velvety flesh, trying to turn away, but Nightmare’s hold was solid. She looked up defiantly, only to feel her thoughts grow hazy as their eyes met. She closed them quickly, but the damage was done as the word “surrender” began quietly repeating in her head.

“Lick, Twilight,” she ordered smokily. “Take in my taste. Breathe in my scent. Bask in my warmth. It’s all you want.”

Twilight did as she was told. She couldn’t stop herself, and as her tongue slid against Rarity’s slick marehood, she wasn’t sure she should want to. It felt right. So right. So good.

The alicorn felt fear and excitement rise in her stomach as her hooves slipped downward on their own power and began to play with her mound.That felt right, too.

“Feel my power, Twilight. Feel it compel you. Feel it pleasure you. Only surrender will let you fully embrace it.”

Twilight shook like a leaf. Her entire body buzzed with blissful energy, and she felt dizzy as the scent of the Nightmare’s arousal filled her nostrils. Her own hooves had betrayed her, pulling her open and teasing at her clit, and every helpless lick sent a red hot bolt of ecstasy racing through her. Through it all, the voice in her head repeated its relentless mantra. “Surrender, surrender, surrender.”

Was this what it meant to surrender? The ecstasy, the feeling of belonging, of rightness? If this was what Rarity had given in to, she couldn’t be blamed. With each passing second, Twilight felt her resistance fading, and with it, her certainty that she wanted to resist at all.

With the rest of her running on autopilot, Twilight’s eyes drifted upward, where she found Rarity’s waiting for them. The princess’ world fell away, narrowing to those two sapphire points, and a ragged, moaning voice panted, “You’re mine, Twilight. We both know it. Say it. Say you surrender, and pleasure like nothing you’ve ever known awaits.” The eyes grimaced, and Twilight felt her body beginning to seize with ecstatic tension. “Say it! I want to hear it!”

Some small, far away part of Twilight knew she could say no, but she didn’t want to. This was her place, and she knew it.

“I surrender.”

The world exploded into a kaleidoscopic comet burst of pure ecstasy. Twilight’s vision was filled with stars, and though she couldn’t hear, her body sang a symphony of bliss unbound. Lightning danced through every nerve, she was suffocating under the weight of her own pleasure, but she didn’t care. She didn’t want it to stop.

Slowly, very slowly, Twilight felt her senses returning. She was dazed, but she could feel something snuggled into her chest. It was panting weakly, whatever it was, and she was fairly certain it was telling her something, but she couldn’t quite understand. The only words that seemed to make sense were, “Come back to me.”

Her ears perked up, and she groaned, trying to focus on her hearing. The effort paid off for precisely one word.

“Sleep.”

Author's Note

Rarity doesn’t mess around when it comes to her couples recreation, does she? It’s gonna be a hell of a ten year anniversary. Of course, one has to wonder how Twilight’s gonna feel once she’s back to normal.

As always, thanks in advance for pointing out any spelling/grammar issues, and thank you for reading!
