Trying New Things

Gleaming Shield slumped back on her bed, her unfamiliarly heavy chest heaving as the sweat began to cool on her body. The bed creaked and moved just a little as Cadance crawled up from between Gleaming's legs and lay down next to her.

Cadance luxuriantly licked her sodden fingers clean. “So, dear, how was your very first time as a mare?”

When Cadance had said they might try a few new things in bed during their trip to Canterlot, Gleaming – Shining at the time – had thought she might be talking about a new position, or maybe some scented candles or something. Gleaming still couldn't breathe quite as well as she wanted to after that mind-shattering orgasm she'd just gotten from her wife's tongue, but she had to spare the breath to say, “I... I can't believe I let you do that to me...”

Grinning at Gleaming wryly, Cadance traced her fingers up her wife's smooth-furred belly, up and over her impressive white tits. “I can believe it. You are a bit of a slut sometimes, you know.”

The sound of that word made Gleaming's breath pause for a fraction of a second ... which Cadance must have felt through her fingers.

She'd always been very good at reading Gleaming's emotions. Cadance wasn't the Princess of Love for nothing. She pinched one of Gleaming's nipples playfully. “If I didn't know any better, I might think you liked it just then, when I called you my little ... slut.”

Gleaming tried to hide it, but she knew the slight twitch that ran through her body must have betrayed her to her perceptive wife.

Cadance smiled and licked her lips. “I'll just have to save that little tidbit away for later.” She came in closer and whispered in Gleaming's ear, “Who knows when information like that might come in handy?”

Already far beyond her comfort zone, Gleaming decided that she needed to change the subject and soon ... before her wife came up with any more ideas. “So, are you excited for the start of the big summit with the other three princesses tomorrow? I know I'm looking forward to meeting some of my old guard buddies – I haven't seen them since we moved to the Crystal Empire.”

“The summit? Sure, it will be nice to catch up with my aunties for a little while, but it's mostly just an excuse to come here to Canterlot and meet with Twilight for a few days.”

Mostly recovered from her first female orgasm now, Gleaming sat up a little bit. “Twilight...? Couldn't we have just gone to Ponyville? Or, she'd be welcome to come stay in the Crystal Palace anytime.”

“It's not for anything that we'd want ponies guessing about. If ponies knew that either of us had traveled so far just to speak to the other, it might lead to the kind of speculation that would end up being scandalous.”

Gleaming thought for a moment. “I know there aren't any scandal-worthy intrigues between the Crystal Empire and the town of Ponyville ... so she must be coming for personal advice ... and you are the Princess of Love, so...”

Cadance shushed her with a finger against her lips. The finger still carried a bit of flavor from Gleaming's pussy, but Cadance held it there nonetheless. “If you ever want me to reverse the spell and make you a stallion again, you won't finish that sentence. State secrets are at stake.”

Looking in her eye, Gleaming saw that she was entirely serious... Too serious. She laughed a little, and Cadance burst out into a fit of giggles as well.

“So,” gleaming finally managed to get out, “our little bookworm is finally seeking out romance from somewhere other than a cheap novel... And she came to you for help?”

Cadance ran her fingers through her mane. “Of course. I'm the foremost expert on matters of love, aren't I?”

“But this is Twilight we're talking about...” Just for the hell of it, because nopony could stop her, Gleaming reached out and fondled one of her own breasts. They were a little bit bigger than Cadance's, and having them touched felt very interesting ... but she couldn’t get too distracted with that. “It was only a few years ago that Twiley managed to make any real friends... Do you really think you'll be able to get through to her?”

A quite un-princess-like snort came from Cadance's muzzle, where it rested against the crook of Gleaming's neck. “When I first met you, you never would have looked at a mare twice unless she'd been issued to you by your guard unit.” She kissed Gleaming on the cheek. “I got through to you, didn't I?”

Gleaming shrugged, then looked down across her own body. It was fun to look at ... but as she looked down between her legs, she couldn’t help but feel that something very crucial was very much absent. Maybe it was just from the unfamiliarity, but every time she looked down there and didn't see what she was expecting, it sent a little shiver through her. “Speaking of things that were issued to me,” she said, “could we maybe reverse the spell now?”

“Aw, is my little slut tired already?”

Something inside Gleaming's lower belly tingled when she heard her wife say that ... but she was ready to change back, temptation or no temptation. “I would just be more comfortable, you know, for sleeping.” She touched her own boobs again, as if to point out how awkward they'd be to sleep with ... but really, she just wanted to touch them, one last time, before they went away.

The look Cadance gave her made it clear that she wasn't buying that explanation in the slightest, but she didn't argue. “Alright,” she said, getting up on her knees on the bed, looming over Gleaming. Her body was truly amazing, and worth taking a moment to gawk at as she prepared. “One gender reversing spell reversal, coming right up.” Her horn glowed brightly, the tendrils of magic arcing down toward Gleaming's body...

Where they bounced right off of her, flinging themselves back into Cadance's horn. The magical impact knocked Cadance flat onto her back.

Gleaming rushed over to her. “Are you okay?”

Shaking the stars out of her eyes, Cadance propped herself up, then waved away Gleaming's helping hands. “I'm fine, I'm fine... But it looks like reversing the spell isn't as simple as just casting it a second time... I may have to figure out something different.”

“Figure out something different?” Gleaming stumbled backward and fell back onto the bed. “W-what's that supposed to mean? Change me back!”

Cadance sighed as she propped herself back up on the bed, rubbing her forehead near the base of her horn. “Take it easy on me, okay? It's my first time with this. I'm sure I'll figure it out soon.”

As Gleaming Shield got up and began pacing worriedly around the guest bedroom with her arms crossed in front of her bountiful chest, Cadance went back to the spell book she'd borrowed from Twilight, almost burying her nose in it to avoid her spouse's distracting pacing back and forth across the room.

Gleaming herself was thankful that her wife was taking this seriously enough to not even bother getting dressed before searching for a solution. Sadly, she was a bit too distracted with worries about her own body to take any enjoyment from seeing Cadance sitting there in the nude.

Eventually, though, Cadance looked up from her book. Gleaming stopped pacing immediately and faced her. “Did you find something?”

“I did ... but you're not going to like it.”

“Tell me!”

Cadance sighed. “Okay. It looks like the spell can't be reversed by any outside force ... it has to keep going until it runs out of energy and reverses all on its own.”

“And how long does that take?”

Looking back into her book, Cadance ran her finger down along the pertinent section of the page. “Well, it depends on your age and weight, the phase of the moon and how many days there are until the next equinox, and then I have to account for the fact that I'm an alicorn, not a unicorn like this book was written for, so the initial energy of the spell would have been higher...”

“How long?” Gleaming took a desperate step forward, coming closer to Cadance, even though she had no idea what she'd do if she got there.

“Just a moment, dear. Calm down.” Cadance tapped her fingers together and stared off into space, mentally calculating.

'Calm down'? Gleaming's legs twitched, and she would have paced again if she could have done so without looking away from Cadance for even a moment. Come on! How was she supposed to be calm in a situation like this?

“About two days and six hours,” Cadance finally said, closing the book and setting it aside.

“Two days?” Gleaming's mouth gaped open, her eyes cringing in disbelief.

Cadance nodded slowly. “And six hours.”

“Ugh!” Gleaming threw herself down onto the bed, face first. “I can't do this! I can't stay cooped up in this room for two whole days with nothing to do!” Her voice was muffled by the sheets, but clear enough to understand.

Though she did take a moment to admire the view of Gleaming's taut little ass, Cadance was by her wife's side in no time, rubbing her shoulder comfortingly. “Well,” she said, “maybe you don't have to stay in here.”

Gleaming twisted her neck around and shot Cadance a baleful look. “I can't show myself in public like this! I'll never be able to live it down!”

“Don't be ridiculous. All you need is some work on your mane and a little makeup, and nopony would ever recognize you. Think about it. If you saw some mare around town that looked vaguely like one of your friends in the guard, you wouldn't assume it was him, turned into a mare, now would you? At most, you'd assume that she was his sister or something.”

For a long moment, Gleaming looked up at Cadance, deep in thought. “Maybe...” She glanced away, then looked back. “I could take a little 'vacation' back to my old guard unit ... as a new recruit. That might be interesting.”

Cadance smiled and shook her head. “Oh you... You have such a weird idea of what a 'vacation' is. But I don't see why that wouldn’t work, if that's what you want to do. Any new recruit with a letter of recommendation from the Princess of the Crystal Empire and the former Captain of the Royal Guard should have no problem getting placement with the Canterlot Palace unit. Everypony knows that they're mostly just ceremonial.”

“Hey!” Gleaming pouted.

“Oh, shush. You know it's true.”

Gleaming rolled her eyes. “How am I going to get a letter of recommendation from my former self, anyway?”

Giving her a playful slap on the rump, Cadance laughed a little. “Getting turned into a mare didn't change your handwriting, did it? Are you going to tell me that you can't replicate that special flair on your signature without holding your penis in your other hand?”

“Oh.” Gleaming blinked at her. “Right.”

Getting up from the bed, Cadance pulled Gleaming along by the hand behind her. “Come on. It's time to give you a makeover!”

* * *

Gleaming stood in front of the full-body mirror in the suite's bathroom, still quite nude. The first thing Cadance had done was to primp Gleaming's mane into a completely different style. Gone were the spiky ruffles Shining Armor had once sported. Now, Gleaming Shield had a flowingly smooth manestyle that, while still fairly short for a mare, actually did look really nice.

Just now, Cadance was down on her knees beside Gleaming's right flank, putting the finishing touches on Gleaming's new cutie mark with deft strokes of her waterproof makeup brushes. On her left flank, Gleaming already had the finished design: a black beetle that utilized the shield design as the bug's shell and the stars above it as the bug's eyes. It really was quite skillful, though Gleaming wasn't sure she liked the idea of having a beetle for a cutie mark. And maybe it wasn't necessary to disguise her cutie mark at all, since her new guard uniform ought to cover it up anyway ... but it was better to be safe than sorry.

Letting her flank get so much detailed attention from Cadance was nothing to complain about, either. The skilful little brush strokes reminded gleaming of the way Cadance's fingers had stroked her needy little mare pussy...

“There,” Cadance said abruptly. “All done!”

Gleaming looked down, and indeed, the beetle on the right side now matched the one on the left perfectly. No small feat for freehand artwork done on fur! It was too bad Cadance would have to stop touching her flank now, though...

Cadance appraised Gleaming's body and tapped her chin thoughtfully. “Now all we need is some clothes for you...” She grinned. “I know just the thing!”

Gleaming didn't much care for the look on Cadance's face, but she couldn’t argue – she did need clothes, clothes that would fit her as a mare.

The first thing Cadance pulled out after dragging Gleaming back into the bedroom with her was a lacy red bra. She held it out to Gleaming with a self-satisfied smile.

Gleaming had seen Cadance wearing this one in the past, and knew that the red looked really good on her, but she still wasn't sure about it herself. “You're sure I really need one?” she asked.

With a roll of her eyes, Cadance pointed to Gleaming's chest with her free hand. “With a bust like that? Yes, you definitely need one. Here, take it.”

Though she did take it when offered, Gleaming ended up just holding it there in front of her. She was actually not terribly sure what was the right way to put it on, and she wished she'd paid more attention to other mares – especially her wife – when they put their bras back on. She looked up at Cadance with a bit of a pleading expression. “A little help?”

“No, dear. You'll need to figure out how to do it for yourself if you're going to live as a mare for a couple days. Go on, give it a try. It isn't complicated.”

It seemed plenty complicated to Gleaming. She fumbled with the straps, trying to worm her arms through them; she held the cups up to her breasts, then started over again and again because the cups would fall off before she could get the straps on; and she cursed at the infernal contraption when she somehow popped one of the shoulder straps completely off ... but she did finally get it in place. Her breasts bulged out between the cups – hers were a bit bigger than Cadance's, apparently, and they didn't quite fit this bra. But the biggest problem Gleaming had was with the clasps in the back. No matter what she tried, nothing seemed to work.

When Cadance giggled at her, she looked over at the pink alicorn dourly. “Oh come on. You know it's my first time with this ... and I'm more used to taking these off ... how the heck does anypony ever get them on?”

Thankfully for her, Cadance took mercy on her and snapped the clasps behind Gleaming's back with a bit of her magic. But then she held up the next bit: a tiny, lace-embellished red thong.

Gleaming stared at it. “Really?”

“I just want to see how sexy you'll look in it.” Cadance gave her a quick kiss. “And besides, it will be covered up by your guard uniform the whole time, so nopony else will see it. Go ahead.”

With a sigh, Gleaming took the tiny lace panties from Cadance's hand. She recognized these, too. They had played a part in quite a few of her idle fantasies back when she'd been male, back when her wife had been the one wearing them, back when things were a lot less confusing.

Once she had those on, Cadance gratuitously grabbed her ass. “Mmm,” she moaned into Gleaming's ear. “Oh yes, that's very nice.”

Despite herself, Gleaming felt her body responding to the attention ... and her wife's still-nude body in front of her was quite the temptation. And there was no real reason she shouldn't indulge again. One nice benefit of this female body was the lack of refractory time.

But, no... The two of them couldn’t spend all day here in the bedroom. Well, Gleaming might be able to get away with it, but Cadance had public appearances to make, private meetings with Twilight Sparkle to arrange...

So it was all for the best when Cadance decided she was done groping and instead fired up her horn, teleporting in a female guard uniform from ... who knew where. Gleaming hoped that her wife hadn't left some poor guardspony mare suddenly naked in the hallway somewhere.

The guard uniform turned out to be a bit too small for Gleaming. No matter how much she tugged on it, prodded it, adjusted its laces, she still worried about the way it pushed up on her breasts, showing off more cleavage than necessary. And the plated skirt was just a little bit too short for her comfort.

Cadance paced around her, checking her out with a critical – but quite appreciative – eye. “You should probably avoid bending over, if you can.”

With a slight wince, Gleaming brushed down the edges of the lightly armored skirt again.

“Or do bend over,” Cadance whispered closely into her ear, “as long as I can see you when you do it.” She gave Gleaming a quick little grope under the skirt, squeezing her thong-clad ass cheek.

Gleaming held her legs tightly together and stood nervously straight as her wife moved back to see her from a different angle. She'd never quite realized just how revealing the female guard uniforms were. She felt entirely exposed ... and while even the male version of the armor didn't provide all that much protection, she surely hoped that no combat situations arose while she was wearing this. Even if she somehow managed to avoid any injuries, there was no way she'd be able to stop everyone nearby from getting an eyeful.

“Oh don't look so dour.” Cadance laughed, then came in close to give Gleaming a playful kiss on the cheek. “There's nothing to worry about. Just go out in Canterlot and have some fun, okay?”

Little did either of them know at the time, but Gleaming was going to have quite a bit more 'fun' in Canterlot than anyone anticipated.

* * *

First Lieutenant Steel Sabre frowned a little as he perused Gleaming Shield's application paperwork, laid neatly out on the large wooden desk in front of him. “This is all highly irregular.”

Gleaming stood rigidly at attention in front of the desk. The Lieutenant had never given the 'at ease' command. So she barely dared move a muscle. “My apologies, Sir. But everything should be in order.”

“Yes, yes...” He glanced over the paperwork again, his eyes coming to rest on the letter of recommendation and its shiny royal seal. “It seems we will have to make a small exception to our normal routines.”

“Thank you, Sir!”

His frown deepened at this show of enthusiasm. Gleaming knew that it was just short of what could be written up as breaking military bearing. When the Lieutenant spoke again, it was with a hint of venomous pleasure: “Luckily, the female guards' morning training regimen is just now beginning. I do think Captain Everwatch will appreciate the opportunity to put you through your paces and see what you have to offer the Royal Guard. Of course, you'll need to hurry. I hear she's particularly harsh on fresh recruits who show up late.” He grinned evilly. “Be sure to stop by Supply and pick up a training uniform. But don't take too long!”

* * *

Gleaming had rushed her brand new uniform vouchers to the supply desk, in a hurry to get to training on time. She had no desire to be that recruit – showing up late and unannounced. She sure knew how she would treat a fresh recruit back in her days as Guard Captain.

Unfortunately, the rush had meant she didn't check the sizes of what she'd been issued. And she really should have.

She stood and stared at it now – a simple white T-shirt and a pair of running shorts that would be skimpy enough even if they were the right size. But as it was now, they were at least two sizes too small. Could she even fit in these?

Glancing up at the clock on the locker room wall, she knew she didn't have time to go back to supply and argue about getting different sizes. She had to try.

It still felt weird being in the mares' locker room. She'd opened the door and nearly walked into the stallion's room automatically before stopping herself at the last moment. Luckily, nopony had been there to see that screw-up. And it helped that there was no one else in the mare's locker room, either. They must all be forming up for training already. It meant that Gleaming was probably already late ... but at least nopony was watching as she began to undress.

She carefully stowed her guard uniform in an empty locker; she just had to trust that none of the other guards would take it, since she didn't have a lock yet. She also didn't have any kind of sports bra like she'd usually seen the female guards wearing on exercises in the past. The lacy red number Cadance had given her would have to suffice ... hopefully it wouldn't show too easily through the white T-shirt.

Unfortunately, it did. When she finally managed to stretch the thin, breathable fabric over her chest, she could easily see the slanted red cups of the bra, and even a hint of the lacy fringe around it ... but it would have to do. At least it was better than the alternative – her nipples showing through. The shorts were an even tighter fit; Gleaming had to struggle and strain to get them up over her now-wider hips. And when they were in place, she was actually glad she was wearing a tiny thong ... because anything that covered more might have actually ended up slipping out from under the shorts' skimpy coverage. As it was, nearly half of her painted-on cutie mark was visible on either flank, where the shorts had slight cuts on either side.

When she looked at herself in the mirror, she thought she looked more like a porn parody of a guardspony than an actual guard recruit. But it would have to do. She had so little time!

* * *

Gleaming skidded to a stop at the tail of the exercise formation just in time to be quite obviously, seriously late.

“Halt!” Captain Everwatch yelled out. “It looks like we'll have to do the warm-ups over again because somepony had better things to do until now.” She marched down the line of sweating mares as they all slightly groaned at the idea of having to do their workouts over again. When she came up next to Gleaming, she paused for a moment, looking scornfully.

As Gleaming felt the Captain's gaze go up and down her, she trembled slightly, sure that her lacy red bra was easy to see underneath.

The Captain shook her head slowly, her tight-cut black mane not moving an inch. “You see? This is why I don't like taking recruits from the other princesses' guard cadres.” She sneered. “No discipline.”

Now Gleaming also felt the eyes of her fellow guardsponies on her back. It was almost enough to get her breaking into a sweat. She wasn't a bad guard! She'd been the best! That's why she'd become Captain herself, back in the days before she married Cadance ... back before she'd even been a she. Things seemed so much less confusing back then.

“What's your name, Private?”

“Shi—” Gleaming caught herself just in time. “Gleaming Shield, Ma'am.”

“And who was your previous commanding officer, Private Shy Gleaming Shield? I'd like to have a talk with them – about the quality of their troops. You're supposedly the best they had to offer, aren't you? That's awfully pathetic, if you ask me. So who'd you report to in the Crystal Empire? Topaz Lance? Obsidian? Old Diamond Slice? He'd be the kind to have such lax troops, I'm sure.”

Gleaming hesitated for just a moment. She hadn't prepared that much backstory, actually ... and she wasn't sure she was familiar enough with any of those to satisfy any further questions the Captain had. If she said something wrong, it might blow her cover. She needed a commanding officer she knew well enough to pass. Of course! Someone she knew better than anyone! “I reported directly to Shining Armor, Ma'am.”

That actually got the Captain to take a surprised step back. “A private, reporting directly to Prince Shining Armor? What kind of command structure is that? What games are they playing in the Empire? Don't answer that.” She executed a perfect turn on her heels, beginning to stroll back up to the head of the formation. “Private Gleaming Shield, I'll expect you an hour early for tomorrow's training exercises, where I'll be giving you a personal workout, to make up for the time you've lost today. Someone under Shining Armor's command should have no problem keeping up with our most intense workouts.” She reached the head of the formation and turned to face them. “For now, the rest of you lot have been slacking off for long enough. Back to the start – a hundred jumping jacks, on my count. One! Two! Three! ...”

Gleaming let herself be carried along by the familiar routine of the workout. Well, as much as she could, anyway. While she might have wanted to let herself drift off into the routine of it all, there were a few new distractions...

The first thing she noticed, before the Captain even reached the count of five, was that the view had changed substantially. Instead of watching a bunch of sweaty, stinky stallions, she was looking at the backsides of dozens of sweaty, sexy mares. All of them were highly trained guards, muscular and firm ... but there was still a substantial amount of jiggle to see every time they did jumping jacks in unison. And while most of their shorts weren't as tight-fitting as Gleaming's own ... they still didn't leave much to the imagination.

But more than that, Gleaming's own body was betraying her. Everything was just so sensitive. Was it because she'd been magically changed into this body, with hardly any time to get used to it? Or did mares just always feel like this? She felt the bra rubbing ever so slightly against her hardening nipples with every move, the rippling heft of her own breasts with every bounce, the bunching and sliding of her lace-covered silk panties every time she opened and closed her legs.

Was she...? With the next few jumping jacks – “Forty-two! Forty-three! Forty-four!” – she felt a slight wetness in her panties as they moved against her.

Oh Goddess, she was getting turned on from this. No! She had to stop it! She felt sure the other mares would know. They'd see a flush on her face, see a wet spot begin to seep through between her legs ... they'd see something. And then they'd know that their new recruit was some kind of pervert or something. She had to stop it!

But she just couldn't. Even though she knew she shouldn't be looking at mares other than her wife, she couldn’t help but see all the well-toned guardsponies in front of her, bouncing up and down. And she just couldn’t get used to the way her own body kept reminding her of sex – practically begging her to touch herself – at every movement. It was like she was under Cadance's love spell somehow ... but the pony she'd been magically attracted to was her own new body.

She moaned slightly – so quietly she was sure nopony else would hear – as the count reached “Sixty-eight!” This was going to be a long exercise session ... and if she couldn't figure out how to reign in her own arousal, tomorrow's personal session with Captain Everwatch was going to be unbearably taxing.

* * *

Once Gleaming had followed the crowd of sweaty mares back into the locker room and found her uniform again – thankfully untouched – she nearly just whipped her clothes off by habit, she was so exhausted. Having to do workouts was one thing ... but having to do workouts with these two big things on her chest and while so unbearably turned on ... it was a much bigger strain than she was accustomed to for an ordinary morning.

Before she pulled her shirt all the way up, though, she caught sight of another guard mare – a deep grey unicorn mare with an electric blue mane – doing the same: casually pulling her shirt over her head. With one practiced motion, she'd pulled her tight sports bra off at the same time, exposing her comparatively modest bust to Gleaming as if it were nothing at all, then leaning down to peel off her shorts.

It took Gleaming a moment to realize that it was nothing special. Another pair of guardsponies walked past her, absolutely naked except for towels hung over their shoulders, casually chatting about some noble they'd been getting annoyed by on their last shift and hoping that he wouldn't come back for this shift. The mares were simply undressing and heading to the showers ... just as she had so many times back with the stallions, back when she had been just one of the guys.

But now that she was aware of it, she hesitated to pull her shirt the rest of the way up and over her head. What if the other ponies saw her?

Focus, she told herself. It doesn't mean anything. We're all mares here, and most of them probably don't even want to look ... no more than I wanted to look at other stallions back when I was one. It's okay to get undressed. And there's nothing sexual about it, she admonished her unruly body. So don't get all wet and horny!

With her resolution made, she pulled the shirt the rest of the way off, and then the shorts as well. She was just about to reach for the clasp of her bra when a hand slapped her gently on the back. “Hey, nice bra, newbie!” A few mares around this section of lockers laughed.

“It's because, well, um...” Gleaming could feel her cheeks heating ... she knew she must have been blushing hard.

The mare who'd touched her back still had her hand there ... the skin-on-skin contact tingled slightly in a way that Gleaming couldn't ignore. But the mare didn't seem to think anything of it. She laughed along with the others. “Hey, don't sweat it. Nopony's going to blame you for showing up late – the Captain usually finds some excuse to screw around with us anyway. We've all been there. Let me guess: long night on the town with some studly guy, then you end up in bed with him all the way until sunrise. Then all the sudden, you have to rush and get dressed and show up bright and early for guard duty! So you throw on whatever you had lying around for your big date night.” She reached down and pulled one of the straps of Gleaming's thong, letting it snap back with an audible pop. “Am I right?”

Gleaming hugged her arms against herself, as if by hiding just a small part of her body, she could completely disappear. “Um ... something like that, sure.”

She laughed again. “Well come on, then. Last one in gets a cold shower!”

Huh. That was a recurring joke in the stallions' locker room, too. And it was no joke or challenge, rather a running criticism of the locker room's chronically inadequate water heater. It was interesting to see that even after all this time since she'd climbed her way up the ranks, even after all the times the castle staff said they were going to upgrade it ... there still wasn't enough hot water to go around.

At least a cold shower would give her a valid excuse for her hardened nipples jutting out so profoundly.

Still, there was no point in delaying things. After taking a deep breath, she unclasped her bra and shrugged it off, pulled her panties down, and stuffed everything into her locker. She was grateful to pick up a towel from the bin and wrap it around at least some of her body... Because no matter how she tried to rationalize it to herself, no matter the unwritten rule of locker rooms being 'thou shalt not stare', no matter how casual everypony else seemed to be about it, she was sure she could still feel everypony's eyes on her as she briskly walked toward the showers. She had to stop herself from running. That would only attract more attention.

When she reached the showers and hung her towel on one of the many hooks, she couldn’t help but stare. This was a utilitarian guardspony shower, just like in the stallions' locker room. And that meant the showers were just a bunch of shower heads sticking out at intervals from the wall in a huge tiled room. And that room was currently full of alluringly fit mares rubbing their own bodies with suds, rinsing themselves off in the hot cascading water, or just chatting with each other as they waited for a shower head to open up.

Gleaming had to wait along with the others who hadn't been able to get in yet. There were only about a dozen shower heads and at least forty mares in this group, so of course some of them would have to wait ... and she'd hardly been the fastest to get here.

So all she could do was watch ... while trying to pretend she wasn't watching. How could she not look at this plethora of sexy, toned mares bathing themselves? It would take more self-control than she could muster. The best she could do was to try and not be too obvious about it ... and try to keep her fingers away from her own slit as it began to drip slightly, begging to be massaged into orgasm as she watched all the beautiful bodies in front of her.

An Afternoon with Twilight Sparkle

If she had been asked back when she was a male guard, she would have said that the boredom of standing watch was one of the worst things about the job. Today, though...

Today, a little boredom was something that Gleaming sorely missed – something she could truly appreciate. So far, it had just been a perfectly normal guard shift, with nothing notable happening. Her report paperwork at the end of the day would be full of 'On duty – nothing to report' entries every hour, on the hour.

She'd been assigned to stand watch over the entrance to the visiting dignitaries' wing of the palace. As she stared down the hallway and watched nothing continue to happen, she wondered whether Cadance might have had something to do with her assignment here. After all, she and Twiley were the only two 'visiting dignitaries' currently in residence. Had Cadance gotten her placed here so that she could toy with Gleaming? It was a possibility. Cadance seemed awfully amused at Gleaming's predicament... It was a little irksome. This was a serious problem. Cadance wouldn't be giggling behind her spouse's back if she had been the one gender-flipped!

The sound of footsteps approaching from behind made Gleaming flinch – was she really that on-edge? This unfamiliar and oversensitive body had her rattled!

When she turned to see who it was, though, she recognized her sister immediately. “Twilight!” she said, smiling. “It's so good to see you!”

Twilight paused, looking at Gleaming askance and with a raised eyebrow.

It took a moment – an embarrassingly long moment – for Gleaming to realize that Twilight hadn't recognized her. If Gleaming had spoken like that to any of the other princesses, she'd be getting reprimanded right now. And even though Twilight was obviously rather lax when it came to official greetings, Gleaming realized with a sinking feeling in her stomach that she'd quite nearly just blown her cover. “Er, um...” She cleared her throat. “I mean, good afternoon, Princess Sparkle.” Giving her best military composure a workout, she stared straight ahead at the empty hallway, showing no expression or emotion whatsoever.

Was it the effort of adjusting to this new body that was making her mess up so easily? She'd never once had a slip-up like that in her days as a guard. With a renewed effort of will, she forced herself to stay focused on the task at hand.

“Oh, okay...” Twilight began walking again, passing by Gleaming on her way out. “Good afternoon to you, too, um... What was your name?”

“Gleaming Shield, Ma'am.”

She nodded politely before continuing on her way. “Good afternoon, Gleaming Shield. It was nice to meet you.”

Just as Gleaming breathed a slight sigh of relief, though, Twilight paused in mid-stride again. She turned back and looked at gleaming, absently rubbing her lower lip with one finger as she gave Gleaming an appraising look.

Gleaming gulped – without showing it, of course. Uh-oh... What was it going to be now?

Instead of continuing down the hall, Twilight came back toward Gleaming. “Say, um... I haven't seen you around the palace before. Are you a new recruit?”

“Yes, Ma'am.” Gleaming nodded cautiously, dreading where this might be going. If she was going to be subject to Twilight's full scrutiny, she might have to start rushing out the made-up details as fast as she could, and she'd better not make a single mistake or contradiction. “I just started today, actually.”

Her eyebrows rose. “They allow fresh recruits to guard such important guests?”

“I transferred in, from the Crystal Empire.”

“Oh! You must have come here with Cadance!”

Gleaming nodded again. “Yes, Ma'am. I traveled along with Princess Cadance.”

“That's funny... You don't look like a crystal pony.” Twilight came closer ... a bit too close, examining Gleaming carefully.

“I moved to the Crystal Empire from, uh...” She couldn't say Canterlot – that was too close to the truth! Twilight might guess who she really was! “From Hoofington. I've been serving in the Crystal Empire guard for years now, but I wanted to transfer back to, um ... be closer to my family.” Well, that was kind of true – Gleaming was very close to one of her family members right now, as it happened. She tried to give a warm, but professional smile. Friendly, but not inappropriate for a guard addressing a princess.

“You must have so many interesting stories from the Crystal Empire...” Twilight leaned against the wall next to Gleaming. It looked like she wasn't going anywhere anytime soon.

“It's, um ... not that interesting, Ma'am. Very little has happened since the Crystalling.” Gleaming tried to ignore the feeling of her unaccustomed clothes rubbing against her ... why did it have to be so distracting? And why was it making her have inappropriate thoughts about her sister? She had to keep those kinds of thoughts out of her head no matter what.

“Oh come on...” Twilight leaned in even closer ... to the point where it was definitely unprofessional. What was she doing? What was going on? She reached a hand up as if to toy with Gleaming's hair, but then lowered it at the last moment, flinching away as if uncertain of herself. “I'm sure you have something to tell me about. Maybe after your shift? When do you get off?”

“I don't get off until sex.” Gleaming's eyes opened wide and she slapped her hands up to cover her mouth. “I mean six! I don't get off until six!” As a little bit of silence stretched between them, Gleaming stood with her very best poker face, despite the heat she felt rushing to her cheeks.

Twilight's own eyes widened a little, and she grinned. She finally broke the awkward bit of silence with, “You know, Gleaming Shield, I can't quite put my finger on why, but I keep feeling like I really have a connection with you...” She wiggled her eyelashes suggestively.

And that's when it hit Gleaming. Of course! Cadance had been giving Twilight lessons on love, right? Twilight must be trying to pick up dates! It all made sense now! It was almost a relief – Twilight wasn't catching on to her disguise; she was just trying to set up some kind of a date with a guard she liked.

As easy as it would have been to simply tell Twilight that she was happily married, Gleaming was curious what kinds of things her wife had been teaching. Just how would Twilight go about trying to pick up the new palace guard, anyway? Wouldn't it be worthwhile to find out? Maybe it would even help Cadance's lessons with Twilight if Gleaming could report back and tell her wife how Twilight had done... The way Twilight looked, with her sleek purple dress and low-cut V of cleavage showing definitely had nothing to do with it. Nothing at all.

“Please,” Gleaming said with a deliberate coquettish lilt and a fluttering of her own eyelashes. “I shouldn't.”

“Oh come on, what's the matter?” Twilight was in the chase now, definitely. She was already giving Gleaming some very alluring bedroom eyes ... and was she wearing more makeup than normal? It was giving Gleaming some very ... uncomfortable feelings about being hit on by her sister. But it wouldn't hurt to continue the experiment just a little longer ... right?

“But I'm just a guard, and you're ... you're a princess.”

“Who cares?” Oh, the way Twilight brushed that serious objection away so flippantly actually did make Gleaming's heart pitter-patter a little. She gave a cute little smile and batted her eyelashes again. “I don't know about you, but I'm definitely willing to make an exception for a mare as—” she looked Gleaming up and down “—exceptional as you.”

Gleaming tried to tamp down the rising heat inside her, but it wasn't entirely successful. It wasn't just the flattery, it was something about her sister's gaze that told her that Twilight really meant it.

“Why don't you take a little break?” Twilight whispered, barely loud enough to hear. “We could get to know each other a little.”

This was starting to go too far, Gleaming was sure. Why was it so hard to breathe? She ... she shouldn't be feeling this way with her sister! As she nervously shifted her legs a little, she felt a bit of wetness in the red lace panties her wife had put on her. Oh Goddess, was she getting wet at the thought of ... doing that with her sister? She gulped, entirely failing to hide it from Twilight. “I can't until I get off – I mean until my shift ends!” Ugh! Why did she keep saying things like that? Was this just a Gleaming thing? She'd never done things like that before, and certainly not with her sister.

Twilight's eyes went wide when she heard that. She even blushed a little herself. But then she moved in to close the deal, edging up so close to Gleaming that their breasts nearly touched. “My, my ... you don't look so good.”

Gleaming could barely breathe. When she spoke, it came out as a kind of a squeak. “I... I'm fine.”

“Maybe you should get off before six ... several times.” Twilight gave her a very knowing look.

The heat was rolling over Gleaming in sultry waves. Where did Twilight learn to be so ... assertive? Why was it making Gleaming so hot and tingly? Was Cadance really that great of a teacher?

“Just look at you... You're red and sweating, and your breathing is so rapid...” Twilight leaned in even closer; her hot breath on Gleaming's neck didn't make things any easier. “... and if your nipples get any harder, I think they're going to poke through that armored breastplate.”

A shiver ran down Gleaming's back. It was true. It was so true... How did she know?

“I'm afraid I'm going to have to invoke my authority as a princess and order you away from your post – for your own good. You obviously need to be relieved, for your own health. Why don't you come back with me to my suite? We'll get that restrictive armor off you and give you a nice, thorough checkup. I'm sure you'll be felling really amazingly good in no time...”

“I can't,” Gleaming objected. “I'm—”

But Twilight was already taking Gleaming's hand and beginning to lead her back down the hall. Gleaming resisted the gentle tug at first. She could have stood her ground and stayed right where she was. She should have. But she didn't. That gentle pull was somehow irresistible ... or was it the way Twilight's legs moved in that silky purple dress?

As much as Gleaming wanted to pretend she didn't feel that way about her own sister, there was no denying it at this point. By the time they reached the end of the short hallway and made it to the door of Twilight's suite, Gleaming couldn't tell if her breath was coming short because of lust or because of panic. She really shouldn't be doing this!

Twilight opened the door, stepped just inside it, and gave Gleaming a sultry look that felt like it could have melted the armor right off of her. That gentle hand tugged her onward again, oh so softly...

But this time, Gleaming stood her ground. Somehow, she knew this was her last stand. If she went in there, if she was alone with Twilight ... there would be no going back from that. There would be no way she could resist. Cadance had told Gleaming to 'have some fun', but did that mean she had permission for this kind of fun? Cadance couldn't possibly have meant that ... could she? It was tempting – oh so tempting – to think that she did have permission.

If Twilight had simply pulled Gleaming's hand harder, that would have been possible to resist. But no... Instead, she gently caressed Gleaming's palm with her fingertips, all the while giving her that look – that 'I know you want me' look. It was pushing all of the right buttons, making Gleaming's whole body tingle with suppressed desire.

Gleaming took a step forward, into Twilight's suite.

Once she was in, Twilight quickly shut the door behind her ... and that knowing look was replaced by a sexy, gleeful grin. Twilight darted forward; Gleaming pressed her back against the closed door, trying to retreat. But that was just what Twilight wanted – she pinned Gleaming against the sturdy wooden door by pressing with her entire body. Gleaming's legs felt weak as she saw her sister's tits pressing against her breastplate, as she felt her sister's hands exploring up and down her body, as she saw her sister's face come closer and closer with a heated look that could only mean one thing...

When the kiss came, Gleaming melted into it willingly. She might have fallen if Twilight wasn't pressing her against the door with her body. Twilight's lips just lightly touched hers in the beginning, but that changed at the sound of the first slight moan Gleaming let out. It seemed to invigorate Twilight, to urge her on. She pressed her lips more firmly to Gleaming's, letting her feel the soft heat and the desire. When Gleaming finally began returning the kiss a little, Twilight took the initiative again, plunging her tongue into Gleaming's mouth without any sense of asking permission. She was taking what she wanted from Gleaming ... and why was that making Gleaming so incredibly aroused? She couldn't stop herself from moaning more deeply and sucking on Twilight's tongue like she was trying to fellate it.

The two of them separated for a moment, a thin strand connecting their mouths before it snapped. Now, when Twilight grinned at her, she seemed to know not only that Gleaming wanted her, but also the way Gleaming wanted her. She pulled Gleaming away from the door and sent her toward the suite's bedroom. “Get in my bed, now,” she ordered, her horn beginning to glow.

Twilight's magic curled around Gleaming's clothes as she stumbled toward the bedroom in a cloud of lust. By the time she made it to the door, most of the lacings had already been undone, and much of her armor was floating next to her rather than remaining attached. Her skirt unbuckled and the padded undershirt beneath the armor slipped forcefully over Gleaming's shoulders. A touch of magic pushed her, and her legs hit the edge of the bed. She fell down on it just as her armor and clothing were tossed in a heap in the corner of the room. Twilight had left her with only the lacy red bra and skimpy panties.

And Twilight herself loomed over her, eying her appreciatively, still fully clothed. “Aren't those lovely,” she said. “Do you wear things like that every day, or were you hoping some visiting dignitary would come and whisk you away?”

For some reason, Gleaming felt it necessary to cover herself with her hands as well as she could, blushing hard. She realized that Cadance had probably dressed her like this knowing that something might happen. But she couldn’t possibly have intended for it to happen with her sister!

Twilight reached down and grazed a finger across Gleaming's bare thighs. “Oh come on, now ... don't hide yourself. It's obvious you were hoping someone would see you like this.”

Gleaming twitched and gasped at the sound of Twilight's voice. Why did it affect her like that?

“Now ... why don't we get those off of you?” Twilight's horn glowed again, brightening the dim room.

Before Gleaming knew what was happening, the clasp of her bra magically unfastened. Her tightly confined breasts immediately came free, bouncing outward a little. And Gleaming could see the slight gleam in Twilight's eyes as she saw that. Maybe it was time to play a little? Gleaming held her hands over the cups of the bra, holding it in place and looking up at Twilight with her best impression of an innocent little virgin. “You... You want me to take it off?”

“No...” Twilight edged in closer, leaning over the bed and reaching out a finger to hook around the small strap between the two cups. “I'm taking it off.” She pulled, and with a little assistance from her magic around the other straps, the whole thing slipped out of Gleaming's grasp, leaving her exposed as her arms were forced out and together to slip the straps off.

She would have rushed to cover herself with her hands again, but Twilight beat her to it, grabbing huge handfuls of her tits with both hands, squeezing them, rubbing their nipples, and pushing them up and together on Gleaming's chest.

Gleaming couldn't help herself. She moaned as Twilight toyed with her bare breasts; she could barely keep herself from begging for more as Twilight pushed her down on the bed, ending up straddling her mostly-nude body. The skirt of Twilight's gown bunched up over her thighs, and Gleaming couldn't help but stare down at the glimpses she got of that between her sister's eagerly-working arms. “Twilight,” she said, ignoring any protocol of proper address, “I can't, I'm—”

Twilight leaned down and kissed her again, deeply and wetly. The objections were cleaned right off of Gleaming's lips before they could make their way out, and Gleaming finally gave in. She reached up above herself, touching Twilight through the gown – the wide swell of her hips, the long sleek curves of her sides, the alluringly plush swelling of her breasts. Gleaming couldn’t feel much through Twilight's gown and bra, but the sheer size of Twilight's endowments surprised her. She'd seen Twilight naked once before, long ago, when they were growing up together. It had just been a mistake, walking in on her in the shower, and she'd only gotten a small glimpse of her sister's breasts back then before quickly ducking out. A lot of shouting and weeks of awkward glances between the two of them had followed, but for some reason, that image had stuck firmly in Gleaming's head right up until this very day. Twilight's breasts were much bigger now... Was that just because she'd grown up since then, or did becoming an alicorn have something to do with it?

Gleaming began fumbling for the tiny zipper on Twilight's gown, suddenly desperate to see her sister naked again, but she didn't manage to pull it down far enough.

Twilight was moving, sliding down Gleaming's body and beginning to lavish Gleaming's tits with her mouth and tongue. Gleaming's fingers trembled and jittered in place at the feeling, taking away any hope she had of unzipping the gown before Twilight continued on sliding down, planting kisses on the bottom of Gleaming's chest, down her toned stomach ... all the way until Twilight's lips met the upper hem of Gleaming's tiny red thong.

And that hem wasn't very high – the panties were cut very salaciously low, barely coming high enough to hide the shallow cleft between Gleaming's pussy lips. She could feel her sister's breath down there, heating her through the soaked-through fabric.

For a brief moment, everything in the universe seemed to hang in perfect suspension, absolutely balanced on the needle point of Gleaming's unspeakable desire for her sister. But then everything came down in an avalanche of debauched lust as Gleaming felt her sister's fingertips slowly trace right down the middle of the soaked red panties.

Gleaming's hips bucked involuntarily when Twilight's finger touched her clit through the thin, silky fabric, but Twilight's hand matched her motion perfectly, staying exactly where she could just barely touch. It was an incredibly skillful touch ... one exactly like Cadance had done earlier, during Gleaming's first time as a mare. Wait... Cadance had been teaching Twilight! Did Cadance teach her this? How would that even happen?

All thoughts of it were driven out of Gleaming's mind when she felt her panties being pulled to the side. No – this couldn't really be happening, could it? Was she really going to let this happen ... with her sister?

Yes. The first touch of Twilight's gentle fingertips on Gleaming's pussy was enough to blow away any thought of stopping this. Why was she so sensitive down there? Even just a little touch on her outer lips was enough to drive her wild with desire, enough to make her legs spasm and shake against the bed.

And it only became more intense from there. Her sister's clever little fingers seemed to be able to touch her anywhere and everywhere at once, teasing her into ever-greater heights of lustful desire. Gleaming thought she might explode on the spot when she felt one of Twilight's fingers slowly begin to slide up inside her, squeezing into the tight opening of her pussy and finding a cozy home inside as it began to wiggle back and forth, touching just the right spots.

Gleaming arched her back and moaned deeply, the distractingly massive tits on her chest heaving up and down with every desperate breath. She clutched at them with both hands; the feeling of having them squeezed just fed back into and intertwined with the pleasure her sister was giving her down between her legs. She could hardly hold it in any longer – she knew it was coming soon. She was just so sensitive – it was like this new body of hers was totally fresh and still on a virgin's hair-trigger.

But then, Twilight slipped one finger out ... then the other. When had she put in another finger? How had the sensations been so intense that Gleaming didn't even notice that?

Twilight's wet fingers instead pulled at the thin waistband of Gleaming's panties, tugging them downward. Gleaming raised her hips a little, helping them slide down her legs and letting Twilight pull them completely off. They were Gleaming's very last scrap of clothing, and losing them left her completely exposed, completely bare in front of her sister. She should have felt shame, should have felt fear or maybe even disgust... But instead, she just felt desire, the burning need to have her sister touch her again, to finally bring her to an incestuous orgasm.

Twilight tossed the panties up on the pillow near Gleaming's head and settled down onto the covers between Gleaming's outstretched legs. She looked up into Gleaming's face over the twin bulges of her tis, and she smiled slightly. “Do you want it?” she asked, her lips so close to Gleaming's pussy that she could feel the heat of Twilight's breath as she spoke.

“Mm-hm!” Gleaming looked down at her and nodded eagerly.

“What do you want?” The teasing tone in Twilight's voice was clear.

Gleaming couldn’t wait that long. “No! Please! I need it – please just do it now!”

“You need it? ... Tell me, just what is it you want from me, and why you want it.”

“Lick me!” Gleaming said desperately. “Please just lick me, Twilight! I need it so badly!”

“Lick you? Lick you where?”

Why did she have to be like this? It was just like when Cadance had done it – had Cadance already taught her this? They'd only been doing lessons for one day! How had they already gotten to this point? And why did her sister have to tease her like this? Why couldn’t she just do it?

“Gleaming Shield,” Twilight said, her breath tickling Gleaming's clit. “Just tell me exactly what you want and why you want it ... and you'll get it. Be a good little slut.”

Gleaming snapped. She couldn't hold it in any longer. “Please please please lick my pussy, Twilight! I'm a slut – I'm a slut for you! Just please put your tongue in my slutty little cunt!”

Twilight smiled up at her from between her legs. “All you had to do was ask.” She winked and then wholeheartedly plunged her muzzle down onto Gleaming's needy pussy.

The contact shot through Gleaming like a lightning bolt, frying her from the inside out with an intense surge of much-needed pleasure. Her pussy had needed this so much that it had felt almost sore as Twilight waited and teased her. But now... Now, now her whole world revolved around her sister's tongue lapping away at her pussy lips and dipping inside to twirl around like magic. Gleaming's hands danced over her whole body which wanted to be touched everywhere at once.

Without taking her mouth fully away from Gleaming's pussy, Twilight pulled back just far enough to speak clearly, her lips still tickling Gleaming's pussy as they moved. “Is that what you wanted, my little slut?”

“Yes! Yes!” Gleaming cried out in return. “Give me everything you— Aaah!”

Twilight had gone right back to it before Gleaming could even finish what she was saying ... and the moment her sister's full attentions were returned, Gleaming didn't want to say anything else. She couldn’t if she'd tried.

It didn't long after that. When Twilight's tongue moved up to her clit, somehow cupping it and rubbing every part of it at once, Gleaming came explosively, her whole body jittering in place as her juices spurted out and marked her sister's face. It seemed to go on and on, longer than any of her orgasms as a male had ever lasted ... and even when it finally began to calm down, a quick insertion of Twilight's finger set her off all over again, turning what would have been a mild aftershock into a desperate finger-squeezing, leg-clenching, and breast-grabbing crescendo.

When the throes of her orgasm finally left her, Gleaming collapsed limply to the bed, struggling just to breathe without passing out. She could barely lift a finger.

So when Twilight brought out some rope from who knows where and tugged Gleaming squarely into the center of the bed, Gleaming didn't even think of resisting. The most she could have managed would have been a feebly questioning moan, anyway.

As Gleaming slowly began to catch her breath and recover, Twilight quickly and efficiently bound up the knots, securing each of Gleaming's arms and legs to the corner bedposts.

By the time Gleaming felt like herself again – as much as she could in this new, hypersensitive body – she found Twilight kneeling over her, tightening the last of the knots on her wrist. It occurred to her that maybe she didn't want to be tied down and put completely at her surprisingly kinky sister's mercy. Her arms and legs were far too securely fastened to do anything with, but she still had her magic. She lit up her horn, beginning to work at the knots. Maybe she'd let herself be tied up someday, but it was definitely something they'd need to talk about and discuss before—

Twilight leaned down and ran her tongue up Gleaming's shimmering horn. The intricate magical patterns warped and dissipated in a shower of sparks as her sister's delicate tongue wrapped halfway around her horn's spirals. And as Gleaming reeled from the slight magical backlash, she felt a small metal ring sliding in place. An inhibitor ring. She could already feel it absorbing what was left of her knot-untying spell, and she knew enough about restraints from her time as a guard to know that even at her best, she probably didn't have enough magical power to overload and shatter any decently-forged inhibitor ring. She was stuck. Why did Twilight even have one of those?

“Can't have you leaving just yet, now can I?” Twilight got up on her knees next to Gleaming, smiling down smugly ... which somehow managed to be incredibly cute. “I haven't had my fun yet!”

With a seemingly effortless flap of her wings, Twilight picked herself up off the bed and stood next to it, where Gleaming could clearly see if she turned her head to the side.

And as soon as Twilight saw that Gleaming was looking at her, she finished what Gleaming had started and unzipped her gown the rest of the way. She didn't just whip it off, though. Instead, she held the now-loose cloth against herself, beginning to dance and sway her hips to some music that nopony else could hear.

Gleaming's eyes went wide. She'd never seen her sister move like that ... and it was beginning to give her a needful feeling in her pussy all over again.

Twilight slowly – oh so slowly – let the gown fall from her shoulders, down her chest, sliding it back and forth against her body as she let it go down. At first Gleaming could only get a few glimpses here and there of Twilight's shockingly bright-pink bra ... but those glimpses grew and built up just like Gleaming's resurgent arousal. Eventually, she could almost always see the generous curves of Twilight's tits cupped in the pink bra ... and more and more, she could see much of Twilight's trim belly exposed bit by bit.

By the time Gleaming caught her first sight of Twilight's matchingly pink panties, she felt like she was ready to burst, already desperate for more ... anything more, as long as it could quench the burning fire growing inside her pussy.

But Twilight wasn't done with her striptease yet, not even when she let the gown fall down her legs and rumple onto the floor. She kept on dancing, putting even more of a swing into her hips now, and coyly letting one of her bra straps fall down her shoulder. Then the other. Without the support, her bra threatened to slip down; it released minutely, letting just a little more of Twilight's breasts slip out of them. Gleaming caught sight of just a little sliver of color that had to be the very upper edge of a nipple.

Suddenly, Twilight paused, freezing in place except for her hands, which came together at the joint between the two bra cups. Giving Gleaming a sly little smile as she did, she twitched her fingers, and the two cups separated ... now the only thing that held them against her breasts were her own hands.

Gleaming's eyes went wide ... and not only at the way those violet boobs moved when they were nearly free from their confinement. She resolved to get herself a bra like that – it would be so much easier to put on...

Any such mundane thoughts were blasted out of Gleaming's head though, when Twilight pulled the remnants of the bra off of herself and let it fall to the ground, spreading her hands apart high over her head as she began to dance again. Those tits! If Gleaming wasn't careful, she was sure that she'd start drooling at the sight of them. They were every bit a match for Gleaming's own ... perhaps a tiny bit smaller, but very nicely rounded and firm-looking. They jiggled and moved a little as Twilight danced, but only a little.

For the first time, Gleaming struggled physically against her restraints. She wanted to touch them! But they were maddeningly out of reach. Was it something about the color, the shape ... or was it simply that they belonged to Gleaming's sister? Why did she want them so much more than her wife's all of the sudden?

The only thing that was able to pull Gleaming's attention away from those bountiful purple breasts was when Twilight tucked each of her thumbs under the front of her neon pink panties, folding the little triangle of fabric forward towards Gleaming and exposing – little by little – the way her belly smoothly curved down and inward, narrowing ... narrowing...

Twilight stopped just when a tiny bit of the cleft between her pussy lips was showing. She paused there, watching Gleaming's eyes. And when she saw the desperation there, she must have known that she'd teased enough, because she flicked her panties the rest of the way down, letting them slide to the floor.

And there, framed by a lovely bit of thigh gap, Gleaming saw her sister's pussy for the very first time. Twilight had been covering it with her hands during the shower incident. Without even thinking about it, Gleaming licked her lips. Twilight's pussy was just so pert and smooth... Yesterday, she would have shuddered at the thought, but now she knew that she'd never be complete unless she could have that. She needed that, and she couldn’t wait for Twilight to come sit on her face, shoving that perfect pussy against her mouth and claiming Gleaming with her drizzling juices...

But Twilight didn't come over to the bed, didn't swing her leg over Gleaming, and didn't drop her pussy down on Gleaming's face. Instead she turned and rummaged around inside a set of drawers next to the bed. It gave Gleaming a fantastic view of her sister's ass and the sweet little pussy lips bulging out between her curvaceous ass cheeks ... but what was she doing over there? Why wasn't she coming to the bed?

A moment later, when Twilight turned around, Gleaming saw it: a rubber horse cock every bit as big as a real stallion's, and already semi-flared at the tip. On the other end was a smaller protuberance and a collection of straps.

“A certain friend of mine taught me that it's important to set up a safe word, both verbal and non-verbal.” She gently inserted the smaller end of the strap-on into her own pussy, spreading the pretty little lips apart a little as it slid inside. “So if at any time it becomes too much for you”— she buckled the straps around her waist and legs —“just say the word 'epistemology' or nod your head up and down three times.”

Gleaming took one more look at that huge rubber cock as Twilight came around and got into place between her legs, then began nodding frantically. “Ephis— Eppistimololly... Uh, Episte—”

Twilight came closer, leaning over Gleaming's body and letting the rubber cock slide up against Gleaming's belly. “Already?” she asked. “Come on – you're a royal guard! I know you can't scare off that easily.” She gave a sultry look, straight into Gleaming's eyes. “And I can tell you want it. You're my perfect little slut now, and you know you want my cock inside you. You know how good it will make you feel.”

Trembling in place, Gleaming nodded once.

“Now, do you really want me to quit, or do you want me to give you all the fucking your debauched little heart desires?”

Gleaming hesitated, her eyes glancing up and down between the tip of the big rubber cock, her sister's lovely boobs hanging down over her own, and her sister's knowing gaze. Twilight's eyes told her that Twilight already knew what the choice would be.

So did Gleaming, for that matter. Squeezing her eyes shut, she blurted out, “Yes, do it! Shove your big cock inside my slutty little pussy!”

That was all Twilight needed. Sliding back down Gleaming's spread-eagled body, she lined the tip of her strap-on up against Gleaming's pussy and immediately shoved it inside.

If Gleaming hadn't been so soaking, sopping wet, it probably would have hurt ... but the broad tip of Twilight's rubber cock glided easily inside, spreading Gleaming's pussy lips open wider than they'd ever been before as if it was nothing. Twilight gave another thrust, and a huge portion of the shaft slid inside, swelling Gleaming from the inside out in a way she'd never experienced before in her life.

Gleaming wanted to reach up and grab her sister, to hold her close and clench her legs around Twilight’s back, but the ropes kept her exactly in place as Twilight hilted her strap-on. The two of them paused for a moment, desperately breathing as they both came to terms with the other's body.

Twilight recovered long before Gleaming did, though. She moved her hips in long, rocking motions that thrust the false cock deep inside Gleaming every time, rippling its rubber veins over Gleaming's inner walls with its every motion. And as things slickened even more, Twilight grew bolder, pounding into Gleaming's pussy recklessly, slamming their hips together with a clapping jolt over and over again.

Gleaming hit her next orgasm before she was even aware that she was building up toward it. Her body spasmed as much as it could between the ropes, milking Twilight's rubber cock as it continued pushing inside her over and over. Twilight obviously knew Gleaming was getting off – the pitch of Gleaming's moans made that obvious enough – but she kept on going, not stopping for a moment, which only made the orgasm extend longer and longer.

And even when Gleaming finally went limp, Twilight only increased her pace, beginning to breathe heavily herself as her tits swung back and forth above Gleaming's chest.

Gleaming never had a chance to recover from her orgasm. Instead of decreasing and dissipating, her pleasure only grew and grew, until it washed over her in overwhelming proportions. She couldn’t stop the sounds coming from her mouth now – a mixture of raucous screams, deep moans, and cries of “Yes! Yes! Fuck your slut! Fuck me, Twilight!”

“Oh no you don't,” Twilight said. “You don't get to talk. That's not what you're here for.” With her magic – and without pausing in her intense rhythm – she levitated Gleaming's panties and stuffed them into Gleaming's mouth, mid-scream. Gleaming let out a muffled yelp of surprise, then another deep, reverberating moan as she felt Twilight wrapping a strand of ... something between her lips and around the back of her head. It turned the panties into an effective gag.

“How do you like the taste of your own pussy?”

Gleaming tried to say that it was too much for her to handle, that Twilight was going too fast and too hard for her ... but it just came out as a mumbled mess.

“Yes...” Twilight's punishing pace grew even more intense. “You like it, don't you?” Even as beads of sweat started appearing on her brow, she managed to spare the energy to roughly grope Gleaming's tits, her fingers pressing deep into the soft flesh before moving up to pinch Gleaming's nipples almost cruelly hard. All the while, her thrusts grew more frantic, her face redder, until she, too was moaning and beginning to tremble.

“I'm going to get you assigned to my personal guard,” Twilight said, slamming her cock home inside Gleaming's pussy. “It's going to be your new permanent assignment, and I'm going to keep you very close.”

“Mmm...” Gleaming strained against the ropes, wishing she could get even closer right now.

Encouraged by Gleaming's reaction, Twilight continued, “Let's see you keep your bearing and stand at attention with a remote-controlled vibrator deep, deep inside your slutty little cunt. I'm going to set you up for an inspection and turn it up to the maximum just as your commanding officer comes up to you.”

“Mmm!”

“And maybe, if you're really good, I'll put one up your ass as well!”

“Mmm!”

Twilight somehow became even more rough with her thrusting, making Gleaming's pussy sparkle with shimmers of pleasure all over. With each rough slap of flesh against flesh, she let out another syllable. “And I'll make a lit-tle alt-er-at-ion to your un-i-form: a coll-ar that says 'Prin-cess Twi-light's Per-son-al...” She gave one final, brutal push. “... Slut.”

At that very moment, Gleaming came again, her pussy clenching down hard on Twilight's strap-on, her whole body roiling with the reverberations of Twilight's words and Twilight's wonderful rubber cock filling her nearly to the point of bursting.

Twilight tried to keep going, but the way Gleaming's pussy was squeezing down on the strap-on must have made the other end of it move differently inside her, because after just a couple more thrusts, she stopped in place, her own body jittering and her chest heaving as her own orgasm hit. Her body collapsed against Gleaming's, and she squeezed the other mare tightly against her as both of their bodies convulsed against and – in a way – within each other. Twilight's muzzle tucked tightly into the crook of Gleaming's neck, her breaths blowing hotly against the base of Gleaming's mane.

It was all perfect ... or nearly perfect. Gleaming was desperate to wrap her arms around her sister and squeeze her tight as both of their orgasms began to fade and calm, but the ropes held her fast, preventing her half of that incestuous embrace.

When Twilight – trembling and weakened – finally pulled her strap-on out of Gleaming and untied the ropes with a flick of her magic, it was all she could do to roll off to the side and breathe.

Gleaming finally got that embrace she wanted, rolling over in turn – barely even bothering to remove the panty-gag from her mouth – and pressing herself close against her sister. Their warm breasts mashed against each other, but she pulled her sister in tight anyway, desperate to feel close. For a moment, she almost admitted to Twilight who she really was ... but no. That might ruin the moment, and the last thing she wanted to do was ruin this beautiful moment.

Eventually, Gleaming ended up with her back toward Twilight, letting her younger sister be the bigger spoon between them and reveling in the way Twilight's sleepy hands wandered over her body, exploring every detail. The strap-on, which neither of them had the energy to remove, was wedged tightly – and a little wetly – against Gleaming's tail.

Twilight's wandering hand finally came to rest with a couple of her fingers dipped into Gleaming's warm, wet pussy, where they stayed. Twilight had fallen asleep with her fingers still inside ... and Gleaming didn't last much longer before drifting off herself.

An Impromptu Royal Summit

It had been several days, the all-princess summit was almost over, and Twilight still hadn't been able to find that very special guard mare she'd taken into her bed. She'd searched practically everywhere. She'd even asked discreetly around at the Royal Guard's headquarters. They confirmed that they'd had a guard named Gleaming Shield ... but only for one day. Gleaming had been permanently stricken off the roster when she disappeared on her first day and then failed to show up for duty on her second day with no explanation. She hadn't been seen since.

Twilight hadn't seen Gleaming at all since falling asleep by her side. It had felt so good to fall into that afternoon nap with somepony she felt so inexplicably comfortable and familiar with ... but when she'd woken up, she had found her bed empty, and no sign of the guard mare who'd been there with her. If it weren't for the confirmation from the Royal Guard, she might be tempted to think that she imagined the whole thing.

She stood in front of the door to Cadance's guest suite in the palace. It wasn't time yet for their daily unofficial teaching session – one of the last remaining ones before Cadance returned to the Crystal Empire – but Twilight knew Cadance would be in there ... and even though she'd at first wanted to keep her brief affair with Gleaming Shield private to just the two of them, it was obviously time to seek some expert help. Cadance had promised Twilight that she could come any time to ask for advice about love and relationships, and this was something Twilight definitely needed advice about. Cadance would just have to find out about it. Breathing one deep breath in preparation, Twilight knocked on the suite's door.

It took a moment, but soon enough, Cadance opened the door. “Oh, it's you,” she said. “Please, come in! I wasn't expecting you until later in the evening...”

Twilight followed her inside, finding a castle suite almost identical to her own. Shining armor was at the other side of the room. For some reason, he blushed and looked away when he saw Twilight's face.

“So, Twilight,” Cadance said as she guided her to a plush chair nearby, “What brings you here so early? It must be something important, right?”

Twilight leaned in close and whispered, “I need a little help with, um... It's kind of about those private meetings we've been having.” She glanced over at Shining Armor meaningfully.

Cadance definitely caught her glance, but instead of politely suggesting that Shining leave the room, she just smiled and shrugged a little. “He knows. Don't worry, though. He's been sworn to absolute secrecy with an oath of honor ... and you know about him and honor.”

Smiling, Twilight nodded. That was true enough ... but could she really say this in front of her own brother? She really needed Cadance's advice, but Cadance might not yet understand just how intimate of a subject they were about to broach. As far as Cadance knew, all their love-lessons were purely theoretical at the moment ... except for the demonstrations, of course. But that didn't count. It was just for educational purposes.

Cadance reached out and put a gentle hand on Twilight's shoulder. “Don't worry, Twilight. Remember the breathing exercise I taught you?” She demonstrated quickly, taking a deep breath along with the arm motion of casting your worries away. “You can tell me anything, and there won't be any judgment whatsoever. I'm here for you.”

Twilight took a deep breath, just like Cadance recommended. It was surprising, really, just how much she'd been learning from her old foalsitter and now sister-in-law lately. Okay, time to spill it. “I've... I've met a mare.”

Cadance's eyes widened, and she drew closer, her interest piqued.

“And she was wonderful! We went... I took her back to my suite, and... And we did it, Cadance! Just like you taught me! I was assertive, and I made sure she knew what I wanted, and she just let me do it! She really did! And oh, Cadance, what a mare! She acted all shy and reluctant at first, but I could tell that she was getting turned on – I could practically smell it. And ... and I just took her back to my room, undressed her, and took her! It was amazing! Just the taste of her ... it was electrifying, and somehow familiar at the same time!”

Shining Armor coughed suddenly, turning away and trying to pay extra attention to the old magazine he'd taken up reading when the conversation began.

“Oh, Cadance,” Twilight gushed, “she was so gorgeous! I did it everything just like you taught me, and she—”

“You did everything I taught you?” Cadance's eyebrows rose.

“Oh yes.” Twilight continued in a whisper too soft for Shining Armor to possibly hear, “I tied her up and licked her, and she came all over my face! And I used that little you-know-what we got at the boutique store! It was so good! It almost felt like I was doing her with a real cock – in fact, I've actually been doing a lot of research since then, and I think I've found a spell that could—”

“That's all wonderful,” Cadance said, cutting her off before she could go on a tangent about magical research, “but let's stay focused on the matter at hand. What did you need help with?”

“Oh, right. Um... I'm sure she really liked being with me, and she knows I really liked being with her. I wanted to take her out on dates and really get to know her – you know, everything! And she definitely had a good time...”

Cadance gave her a sidelong look. “But...”

“But when I woke up, the bed was empty. She'd just left while I slept! Without even saying goodbye!”

“Ah, I see. Sometimes ponies get a case of cold feet and are afraid of even the slightest kind of long-term commitment. But I'm sure if you just go to her and tell her how you feel, she'll—”

“That's just it! I can't find her anywhere! I've looked and looked, and it's just impossible.” Twilight slumped down onto the nearby couch, resting her head on her hands.

“Oh... Oh dear.” Cadance came over and sat next to her on the couch, holding her arm on Twilight's shoulders to comfort her. “I can't let new love like this go unrequited! Tell me, what did she look like? I swear I'll do everything in my power to help you find her.”

Unseen by either of the mares, Shining Armor winced and buried his face even deeper in his magazine.

“She was one of the palace guards,” Twilight said. “A unicorn with white fur and a blue mane.” She looked off into the middle distance and held her hands out as if feeling a couple somethings. “And her boobs, Cadance. Oh, Goddess, they were so amazing! I've never seen anypony like her before!”

At the sound of the white fur and blue mane, though, Cadance's eyebrows had risen slightly again. “Just a moment... Tell me, what was her name?”

Twilight sighed wistfully. “Gleaming Shield.”

Shining Armor coughed loudly, and his magazine ruffled as he tried to hide under it.

After sparing her husband a very wry glance, Cadance smiled all-too-knowingly, as if that name was the most interesting news she'd ever heard. But she still held Twilight's shoulder just like an old friend should. “Tell me, Twilight, why did you first decide to pursue this Gleaming Shield? The palace guard is hardly the first place any royal pony should look for a partner ... though I know the example I've set myself in that regard isn't exactly ideal. Still, what did you see in her that made you like her so much? Before you got her into the bedroom, that is.”

“It was just something about her...” Twilight paused for a long moment. “Well, to be honest ... first of all, there was just this unplaceable, subconscious sense of familiarity. From the very first time I saw her, for some reason, I felt like I could trust her with anything and she wouldn't let me down. Not just in the way a normal guard is trustworthy – it felt almost as comfortable as being around somepony I'd known my whole life.”

Cadance's knowing grin grew positively mirthful.

“And of course, she was just so plain hot. I've seen a lot of guards in guard uniforms around, of course, but Gleaming... The way that uniform fits her is just so ... ugh.” Twilight looked up at Cadance wistfully. “And then there's the way she acted once she started getting turned on... She was so nervous, trying to hide it, and there was something almost boyish about her, but in a way that was just so pretty and cute!”

Without losing her grin in the slightest, Cadance turned to face Shining Armor. “So, Shiny, what do you think of your sister's story? It's pretty interesting, isn't it?”

For a moment, he peeked up above the edge of his magazine, blushing fiercely, before snapping it up to hide his face again. Why was he acting like that, Twilight wondered. And why would Cadance – the world-renowned expert on love – need to ask her husband's opinion about it?

“Well?” Cadance asked with just a hint of sharpness in her voice.

Slowly, Shining Armor lowered the magazine, using it to cover his lap instead. “That really sounds like a wonderful mare you've found, Twilight. I'm very happy for you.”

“And maybe you'd like to tell Twilight where she can find Gleaming Shield again?”

Shining gulped. “Well, um ... you see, uh... The truth of the matter is, um...”

“Shining?” Twilight said. “Are you okay? What's wrong?”

“Too late!” Cadance giggled as if it was no big deal, even though Shining Armor was clearly distraught about it. She sidled up next to Twilight. “I'll show her.” With a wry little smile, Cadance looked over at her husband. “Oh Shining... Twilight would like to see Gleaming Shield again...” Her horn began to glow.

Shining held his hands up in front of himself. “No! Don't you dare! I'll—”

But it was too late. Before he could reflexively put up an energy shield, Cadance's spell hit him ... and in a momentary flash, he became a she.

Gleaming gasped, and as her now ill-fitting clothes began to slough off of her, she grabbed herself, holding the formal jacket and pants tightly against herself in an effort to keep them from falling off.

Twilight's eyes went wide. “G-gleaming? You're...” Her mouth dropped open, and words failed her.

“Cadance!” Gleaming danced nervously in place. “Ugh! I just changed back, and now I'm Gleaming again already!”

Cadance rose up and started slowly toward Gleaming. “Oh, I think you won’t mind too much. What was it that you said about that little clit-sucking technique of mine? That it was better than anything you'd ever had?”

But she was stopped in her advance toward Gleaming by Twilight grabbing her wrist. “Cadance,” she said. “How can you just tell me all this? It's ... it's...”

“It's nothing to be concerned about.” Cadance came back and wrapped an arm around Twilight. “It's perfectly natural to feel an attraction to your family sometimes, especially when you see them in an unfamiliar, sexy body. Believe me, as the Princess of Love, I've seen it all. And more than that, I've seen enough relationships soured by secrets to know that both in romantic relationships and family relationships, it's often better in the long term if secrets are out in the open. And—” she smiled and winked “—if it means I get to tease Gleaming a little bit, that just makes it all the more fun.”

“No no no no.” Twilight shook her head vigorously – a little too vigorously. She had to stop for a moment and calm herself before she gave herself a headache that way. “That's not possible. Gleaming Shield is a mare. Believe me, I got plenty close enough to be sure of that, and no illusion spell could change the way she felt and smelled ... and tasted.”

“It wasn't an illusion spell, Twilight. It's a very old spell, one I dug up in the Crystal Empire archives. It actually changes a pony temporarily, either from a mare to a stallion or a stallion to a mare. We had been playing around with it a little bit, just to try something new in the bedroom. The problem is ... well, I didn't notice at first that the spell can't simply be re-cast in order to reverse its effects. You have to wait for it to wear off naturally. And of course Shining couldn't just go out like that, as Gleaming Shield. So I made him a little bit of a disguise to go out in. You know, so she wouldn’t go stir-crazy in this room.”

Twilight stared at Cadance. No. There was no way this could be true, no way that Gleaming could have been her brother ... or her sister? How did that even work?

“Only...” She glanced over at Gleaming, who was slowly trying to edge her way out of the room without being noticed. “I didn't expect Gleaming to go so crazy outside, either. Sleeping with your own sister, Dear? Twilight didn't know, but you did. I'd been wondering why you were keeping yourself cooped up in here after making such a big deal about cabin fever earlier... Now your little change of heart makes a lot more sense. What do you have to say for yourself?”

Gleaming froze. “I, um... I didn't mean to. She was just so...”

Cadance smiled. “I suppose that means my training techniques are working well. Have to look on the bright side, don't we?” She looked back over at Twilight.

But Twilight herself was still a few steps back in the conversation. “No no no. There's no way I slept with my own brother. Or sister. Or whatever. I don't believe it. It's just not possible. This has to be some kind of elaborate prank...” She looked around, a bit of crazed desperation in her eyes. “Gleaming? Gleaming, you're waiting behind the curtain or something, aren't you? Ready to come out as soon as I actually believe I slept with Shining Armor. Okay, very funny. But you can come out now.”

Twilight – in a bit of a daze – allowed Cadance to lead her closer to Gleaming.

“There’s only one Gleaming, and she’s right here. Why don't the two of you get reacquainted? I see she’s already well on her way to losing those pesky clothes of hers...”

At the sound of that, Gleaming clutched her clothes against herself all the tighter. But Cadance didn't let her stay like that for long. She slid around behind Gleaming, caressing her husband-now-wife's back and shoulders sensuously as she did ... and when Cadance's hands slipped around Gleaming's waist, running up her sides and over her breasts, Gleaming was too overcome with the sensations running through her extra-sensitive body to do anything about it. Pop. Cadance unbuttoned the top button of Gleaming's red formal suit. Pop. And another one. She worked her way down, keeping Gleaming in rapturous passivity by squeezing a breast in one hand while her other hand busily went down the front, popping loose button after gold-plated button.

Twilight stared, barely able to keep herself from drooling ... both at the sight of Gleaming's emerging cleavage, and because she'd been struck dumb by the thought that Gleaming Shield was Shining Armor. It still wasn't quite sinking in.

Once Cadance had unfastened the final button, she let the suit fall open a little, making it blatantly obvious – from the lack of any strap across the bottom of her cleavage – that Gleaming wasn't wearing any kind of bra. Of course she wasn't – just moments ago, she'd been a stallion! She'd been Twilight's brother! But now ... she was Twilight's sister? And despite herself, Twilight couldn’t help but still want her, despite knowing that.

When Cadance stopped squeezing Gleaming's breasts, though, Gleaming seemed to snap out of the ecstasy-induced haze she'd been swept up in. She breathed heavily and snapped her hands back to either side of her suit. That motion wrapped herself back up tightly, taking away that tantalizing glimpse of white in between.

Instead of using her hands this time, though, Cadance used her voice. “Why are you trying to cover yourself up, darling?” she whispered into Gleaming's ear. “It's obvious your sister has seen your body before – all of it.” She toyed with Gleaming's mane as she moved in even closer. “And I know you enjoyed submitting to your sister, enjoyed being tied up by her and fucked by her.”

Gleaming moaned slightly, barely audible.

“Take it off,” Cadance whispered hotly into her wife's ear, her breath visibly tickling the delicate hairs there. “Show your sister what you want her to touch. I know you want to. She knows you want to. And you know you want to. Do it.”

Shuddering slightly, Gleaming altered her grip on the fabric. And now, instead of holding it closely against herself, she pulled it slowly open, stretching her shoulders back to let the suit fall off behind her.

Twilight's wings sprung out the moment Gleaming's fantastic breasts were exposed, and she blushed hard, her face heating up ... but she didn't look away, not even for a moment.

Cadance held both of Gleaming's breasts up, twiddling her fingers over Gleaming's nipples as she did. Accompanied by the music of Gleaming's growing moans, she said, “Come on, Twilight. Why don't you come over here and give it a try? You must be missing these sweet titties of hers... Come on, touch her.”

Slowly, Twilight came forward. Without even thinking about it, she held her hands up in front of her, already raised palm-up and ready as she stared entranced at the slight ways Gleaming's breasts moved under Cadance's hands. And then, as if she'd just drifted through the bit of intervening time, she was there. She pressed her hands forward, feeling Cadance's fingers for a moment as they slipped out of the way ... then it was just the sweet velvety fur and underlying soft springiness of Gleaming's boobs. A tingle ran up and down Twilight's body. Oh, these felt so nice! She had been missing them ... and it didn't even truly enter into her mind just whose boobs she was touching.

That is, until Gleaming said, “Oh, Twiley ... that feels amazing!”

Suddenly, the idea rushed into Twilight. This was – at least used to be – her brother, Shining Armor! And Gleaming was married to Cadance as well! This was wrong on so many levels. And yet, she couldn't pull her hands away from those fantastic pure-white tits. Even fully realizing whose tits they were, Twilight couldn't stop touching them. They were just that good.

And whatever inhibitions Twilight had left began to melt away as she noticed Cadance's hands sliding down Gleaming's belly. “My wife's tits are incredible, aren't they?” Cadance reached Gleaming's belt buckle and unhooked it. “But the real treasure is down here, isn't it, Gleaming?”

Gleaming moaned even more as her wife unzipped her dress pants, just happening to run a couple fingers up underneath Gleaming's underwear at the same time. Gleaming pressed her chest out toward Twilight and her ass toward Cadance at the same time.

When Cadance ventured a hand down even lower, making Gleaming breathe in strained panting breaths, and then brought it up to her lips and licked a finger clean, she smiled at Twilight. “I think she really likes you, Twilight. She's already soaked down there ... want a taste?” She held up a different finger – one dripping with something clear and clinging, even though it hadn't been in her mouth.

Twilight's own mouth opened before she realized what she was doing ... but when Cadance's finger came close enough, she didn't hesitate. She looked into Gleaming's eyes as she sucked Gleaming's juices off of Cadance's finger. The look Gleaming gave her – of awe-struck lust and the final release of all inhibition – was priceless ... and the flavor wasn't bad, either.

“Why don't you help me with these pants?” Cadance said, already taking her hand back and grabbing at Gleaming's waist.

As if she wasn't even in control of her own actions, Twilight's hands reluctantly left Gleaming's breasts unattended and instead met Cadance's. She helped her sister-in-law shimmy the unforgivingly tight dress pants – and the underwear beneath them – down Gleaming's legs. Twilight knelt down to pull the pants off of Gleaming's legs, which Gleaming helpfully lifted her feet for, and that left her with quite a view when she looked up.

There it was, right in front of her – Gleaming's glistening-wet pussy. Twilight licked her lips ... and after a moment's thought, she leaned forward and licked Gleaming's lips as well. Twilight could feel the jolt that ran through Gleaming's body the moment her tongue made contact. And even though Gleaming didn't move or react in any other way, Twilight knew that her efforts were worth it. Gleaming's hormones and sensitivity must have been going crazy in this unfamiliar body, because she couldn't move at all, couldn’t even manage a moan. She just stood and trembled as her wife held her up from behind.

“Such a slutty little girl,” Cadance said softly, well above Twilight's head. It was obviously meant just for Gleaming's ears, but she could hear it as well. “Just how easily did you knowingly fall for your own sister? And now look – you want her again, don't you?”

“Mmmm!” was all Gleaming could manage as Twilight's tongue delved deeper, her lips pressing against Gleaming's soft and supple pussy.

Cadance laughed slightly, even as she grabbed Gleaming's breasts and slid her hands all over them. “I should have known you well enough to know that you'd like a little rough treatment as a mare. But you know what? I have begun to guess, these nights I've spent with you. And I got something for you.” A tiny pale blue flash of teleportation lit up the room for an instant.

Both Twilight and Gleaming took a moment to see what Cadance had brought.

A collar hung in the air in front of Gleaming, right in front of her face where she could easily read it.

“Tell your sister what the inscription says, darling. She can't read it from down there.”

“It just says...” Gleaming gulped. “Slut.”

“That's right. And it's the perfect accessory for my little Gleaming.” Cadance snapped it in place around Gleaming's neck. “Oh yes ... very nice. I wonder if there's a spell I could use to make it permanently attached. I'd love to see you trying to cover it up for official functions later ... always worrying if some dignitary or other is going to notice it and read it.”

She moaned at the sound of that ... or maybe because Twilight had slipped a couple fingers into the slick warmth of Gleaming's pussy.

Twilight herself bit her lips slightly at the sight of that collar on Gleaming's neck. Even though it was Cadance's idea and Cadance's collar, she really liked the looks of Gleaming wearing that ... even if it was a way for Cadance to lay even more claim to her.

“Do you like your brother as a mare, Twilight?” Cadance smiled down at her.

After planting a long, slow lick right over Gleaming's clit, Twilight looked up at her. “Uh-huh.”

“You still have a little time left for little old me, though, don’t you?”

“Of course. I always will!” Smiling back slightly, she nodded, reaffirming what she'd just said.

Cadance came around behind Twilight instead of Gleaming, lifting Twilight up and slowly unzipping her dress with one hand while her other was already busy groping. “Why don't we share her for a while?” she whispered into Twilight's ear. Something – either the idea or just the sound of the words – sent shivers through Twilight, and by way of answer, she reached out and played with Gleaming's tits again, teasing the wonderfully soft mounds between her hands, even as Cadance managed to slip her dress off, leaving Twilight in only her panties and bra.

At that point, even Gleaming started getting into things, returning a bit of the groping by running her hands up and down Twilight's smooth belly, until one ventured higher to squeeze the cups of Twilight's bra and one ventured lower to rub her through her panties. The two of them only became more enthralled with each other as Cadance slipped Twilight's undergarments off of her. Twilight moaned at the lovely feeling of being touched all over by both of them, and Gleaming came in for a kiss that quickly absorbed both of them completely.

“Ahem,” Cadance said from beside the two of them. “Aren't you two forgetting somepony?” With one quick motion, she unzipped her own gown and let it drop to the floor, revealing that she was completely nude underneath it.

Twilight gaped at her, right along with Gleaming. Both of them had seen Cadance nude before of course, but ... wow. She was still a truly magnificent sight with her big proud nipples even pinker than her breasts and her wide, luscious hips.

With all three of them naked, the threesome began in earnest.

Cadance stole Twilight away first, dragging her over to a couch where the two of them made out frantically, finally letting loose a passion that neither one of them had felt free to express during their training times. Twilight nearly cried out when Cadance's delicate fingers began probing her pussy – Princess of Love or not, where had Cadance even learned to have such a masterful touch?

As Twilight began to return the favor – as best as she could – Cadance instead withdrew her expert touch. She beckoned Gleaming over with the curl of a very wet finger.

“Gleaming,” Cadance said, “You are now my obedient slut and you will do exactly as you're told. Do you understand?”

Gleaming glanced for a moment at her sister's body – her exposed breasts, her dripping pussy, her finger still inside Gleaming's wife – and Gleaming nodded fervently. She was far too horny now to turn back. She needed this ... more than anything, she wanted to be with her sister again. She wanted her sister to tie her up and fuck her again, to use her however she saw fit. And besides ... wasn't it her duty as a wife ... or something?

“Good. Come over in front of the couch – yes, between her legs – and get down on your knees.”

With unbelieving, mechanical movements, Gleaming did as she was told, kneeling between her sister's outstretched legs. Twilight's pussy spread open pinkly right in front of Gleaming.

Cadance grasped Gleaming's horn, making her gasp. And she pulled Gleaming downward, all the way down until the tip of her muzzle bumped wetly against Twilight's pussy. “Lick your sister,” Cadance said. “Start with the outer lips, then do exactly as I say.”

Somewhere above Gleaming's head, Twilight moaned out sharply when Gleaming's tongue made its first contact, even though she'd barely touched her sister's pussy at all, only the outermost edge of her lips.

“Now slide your tongue slowly up, barely touching her.”

Gleaming did as she was told, and when the tip of her tongue was just barely touching Twilight's clit, Cadance told her to lick again, just a little more deeply ... and she did. Every instruction seemed to trigger Twilight even more. Somehow, Cadance knew exactly how to treat Twilight to make her writhe and cry out in passion ... Gleaming decided not to think about how Cadance had come to know her sister-in-law so intimately.

But as Twilight became more and more distracted, her fingers stopped working inside Cadance. Her whole body had basically stopped working, a slave to the pleasure Cadance was giving her, using Gleaming as her tool of choice.

It was soon to be Gleaming's turn to be distracted, though, because once Cadance was no longer being taken care of next to Twilight, she came around behind Gleaming instead. Her words of instruction still came: “Now take your tongue out of her pussy and suck on her clit a little. Yes, just like that. Not too hard, but make her feel it.” But now Gleaming also felt her wife's fingers caressing Gleaming's pussy lips as they bulged slightly out from between her bent legs. Cadance's long middle finger glided easily between Gleaming's lips, her fingers on either side caressing outside of them.

And if ever for a moment Gleaming was overcome by the sensation, Cadance would use her other hand to shove Gleaming back into Twilight's pussy, along with admonishments like, “You can't please your sister with your tongue hanging out in the middle of nowhere like that – get back to it!”

Even when Gleaming was dutifully eating out her sister, Cadance would lean up next to her ear – fingers still working inside her – and whisper things like “How does your sister's pussy taste? Oh right – I already know! It's wonderful isn't it?” and “Just how long have you been waiting to do this, Gleaming?”

Soon, though, Gleaming couldn't quite hear her wife's teasing voice – Twilight gripped her smooth, supple ... but nonetheless powerful thighs around Gleaming's head, holding her there more and more tightly, until it became pointless for Cadance to hold Gleaming in place. As Twilight's voice approached more and more of a fever pitch, Gleaming lost any ability to pay attention to anything else. She was so enthralled by the growingly intense squeezing of Twilight's thighs – not to mention her pussy – that Gleaming barely noticed when Cadance stopped tending to her.

That just let Gleaming give Twilight all the more attention. And although she'd been spending a lot of time with Cadance lately, nopony had spent more time with Twilight than Gleaming. Even though none of that before had been sexual – except that one time, recently – Gleaming still knew her sister better than anypony else. She found that by teasing lightly with her tongue, she could drive Twilight to higher and higher peaks of pleasure, quickly driving her to a point where she screamed out, holding onto Gleaming's horn like it was the handle of a sex toy.

Gleaming eagerly lapped up her sister's juices as the orgasm engulfed her pretty purple body. A shudder of anticipation ran through Gleaming, too, knowing she'd probably be in a state of mindless bliss like that herself before long. And if she was lucky, it would be Twilight who would get her that way.

When Twilight's legs finally released her, Gleaming looked up ... only to see her wife standing over her with a strap-on dangling from her fingertips.

“Twilight isn't the only one who can play dirty,” Cadance said. “And I think it's time I reclaimed my wife's pussy, don't you?”

Gleaming's eyes stayed fixed on the rubber dong. A small part of her wondered where Cadance had gotten it. A bigger part of her was fixated on where Cadance would soon be putting it.

Cadance grinned down at her. “Oh, once you feel this, I bet you'll never want to go back to being male. Then I'm going to have that lovely little pussy of yours every night from now on.”

As Cadance began to wrap the straps of her new toy around her waist, though, Twilight regained at least most of her lucidity. She ran her fingers through Gleaming's hair, then held a finger up, pausing Cadance's efforts. “Actually, Cadance, I think I have a better idea. I was trying to tell you earlier – I've been doing some magical research, and I think I have a spell that will fit this situation very nicely.”

Cadance let the strap-on drop to the floor. “Really? No ... you can't truly be implying ... that, can you?”

With a grin, Twilight let her magic flow. A surprisingly anticlimactic flash came from her horn, and a very real horse cock with matching balls sprouted from between her legs. Of course, that meant Gleaming got a faceful of her sister's balls. It was startling for a moment ... but only for a moment. After that, she made a conscious decision that she was going to be okay with it and gave a tentative lick along the cleft between them.

“Mmm... That feels really nice.” Twilight stroked her new cock and grinned up at Cadance while Gleaming licked her below. “They don't call me the Princess of Friendship – and Magic – for nothing.” Her smile grew into a bit of a smirk. “Want one?”

Cadance glanced down at Gleaming's ass, still upturned toward her. “Do I ever!” She grinned. “Do it! And promise you'll teach me the spell later!”

Twilight nodded, and with another flash of her horn, it was done.

Occupied as she was with her sister's nice, smooth balls, Gleaming couldn't get a good look at what her wife had just grown. But she felt it, the warm, broad tip of it rubbing up and down between her ass cheeks, just barely kissing her pussy from time to time ... but even that was enough to get it soaked and slippery.

But that was just in time for Twilight to lay her long, purple cock over Gleaming's face. The implication was clear – Twilight wanted Gleaming's mouth ... but Gleaming wasn't sure she was ready for that. A little bit of licking the big, smooth balls was one thing ... but taking that huge, somehow feminine, cock inside her mouth? She wasn't sure about that, despite how sure she was about taking her wife's cock inside her pussy.

Despite Gleaming's best efforts, though, Cadance wouldn't let her shove herself down on it.

“We both know you're a raging slut for your little sister,” Cadance said, still teasing Gleaming. “Don't waste our time pretending that you don't want her cock in your mouth.”

Gleaming gulped, then backed up a little, Twilight's cock dragging against her cheek, until she faced the head of it square-on. Still, though, she didn't open her mouth and take it inside, even as she held it steady in front of herself. It was just so thick, meaty, and warm ... could she really do this?

Cadance nudged her forward, to the point where Gleaming's lips touched the tip of Twilight's cock. “Do it,” she said. “If you want my cock inside you, you've got to earn it!”

Closing her eyes to pretend she wasn't doing exactly what she was doing, Gleaming stuck her tongue out, intending to lick up across the broad, flat tip of her sister's cock. But ... she couldn’t. She just couldn’t make herself do it.

Cadance was ready to help, though. Reaching far over Gleaming’s back, she grabbed a handful of Gleaming’s mane and pushed her down. Her outstretched tongue was planted against the warm, meaty surface of Twilight’s cock ... and it was done -- Gleaming had her very first taste.

“Mmm,” Twilight hummed. “That feels nice.” It was so strange, hearing that familiar voice while doing something so strange and new.

Cadance rubbed her own cock up and down Gleaming's slick pussy lips, but she didn't let it slip inside, not yet. “Go on. Earn it.”

First taking a deep breath to prepare herself, Gleaming held her sister's cock with one hand, then slid her tongue up and down Twilight's entire length, lavishing herself on that dark purple cock. After the first couple moments, it no longer felt so strange. Something inside her just clicked, and suddenly that thick shaft between her hand and her mouth didn't feel weird and gross anymore – it felt amazing. The skin of it was so soft, and yet with a heavy, firm warmth that made it almost seem to glow from the inside. Maybe it was magical, or maybe she'd just never realized how much she liked cock before.

Her eyes open and loving every moment now, Gleaming lick-lick-licked herself back up toward the head of Twilight's cock, teasing her sister a little now with short little licks and kisses and rubbing that lovely shaft all over her face ... until she reached the very tip again.

The moment she did, she felt Cadance's cock line up against her pussy, no longer sliding along the outside, but now ready to press in, already spreading her pussy lips apart a little, even though it wasn't quite inside just yet.

Gleaming closed her eyes again and opened her mouth wide, stretching her lips around the tip of her sister's cock. And just as she let it slip fully into her mouth, Cadance pressed from behind. That pushed her deeper on Twilight, but more importantly, that pushed Cadance's warm cock into Gleaming's pussy. She moaned around Twilight's cock, shuddering slightly as she felt the first real cock inside her she'd ever had. With thick, warm cocks in both ends, she felt like she was melting into a puddle of sex, and she loved it.

Her grip faltered on Twilight's cock, her hand slipping free and coming to rest on Twilight's thigh.

She didn't get to enjoy the feeling of her sister's nice smooth leg for long, though. Magic took hold of both her arms – whose magic, she didn't know or really even care – and pulled them together behind her back. Something wrapped around her wrists back there, holding them perfectly in place. At the same moment, a horn ring fitted over her horn, snapping down with a ringing clink. Gleaming was helplessly restrained now, and there was nothing she could do but accept it when Cadance gave a long, hard push from behind.

Cadance gripped Gleaming's ass tightly as she slid more and more of her cock inside. “Ooh, that feels amazing,” she said. “No wonder stallions like it so much... And for a pussy that's never had a cock inside it before, you're so wet – I can just slip right in.” As she said that, she gave a firm final push that sank her cock all the way into Gleaming's pussy, her hips pressing against Gleaming's ass and pushing her forward ... straight onto Twilight's cock.

Gleaming's eyes bulged as she felt her sister's cock sliding down her throat. She could feel every inch of that shaft from her lips, her tongue, and deeper and deeper, pushing in and gliding against the sides of her throat. There wasn't even time to think about any kind of a gag reflex; it was like Twilight's cock just spread her open from the inside out, even as Cadance's stayed hilted and twitching deep inside Gleaming's pussy.

“Oh wow...” Twilight ran her fingers through Gleaming's mane. “That's wonderful. Keep doing it – you're being such a good slut for me.”

Did she think Gleaming was doing it on purpose?

Cadance pushed even more from behind, leaning over Gleaming's back to whisper in her ear, “Take your sister's cock all the way inside, my slutty little wife. I'm not pulling back until I see tears dripping.” She nudged Gleaming forward again, forcing a little bit more of Twilight's cock inside.

Gleaming's neck bulged obscenely, and she couldn't even pause for a breath as Twilight's medial ring bumped past her lips and over her tongue. She whimpered a little, staring up at Twilight's face, her eyes begging for just a little respite, even though the pleasure was by far overwhelming any discomfort.

But Twilight must have interpreted those begging eyes very differently, because she grabbed Gleamings horn and used it to pull Gleaming even further down, all the way until Gleaming's lips kissed against Twilight's sheath. And even then, Twilight didn't let go. She used Gleaming's horn to thrust up and down, abusing Gleaming's throat like some disposable sex toy.

The collar choked Gleaming, squeezing her throat even tighter around Twilight's thick, warm cock. Even as the heat of it seemed to radiate out through her, Gleaming began to sputter and choke – it was just too much! But neither Cadance nor Twilight pulled out of her. They both pressed in deeply, giving tiny little thrusts that barely pulled out at all before pressing back in as deep as they could go again ... and it only became more difficult as Twilight's cock began to flare, the tip of it swelling wide inside Gleaming's throat.

“Ungh!” Twilight gave one last push, burying herself in her sister's maw. “It's too good!” Her flare blossomed out even wider, sealing the tip of her cock against the inside of Gleaming's throat. The leather strap of the collar creaked as it was stretched, but it didn't break. It kept Gleaming's throat tight around her sister's cock as the length of the shaft began to pulse with long, thick gushes of cum headed straight down Gleaming's throat.

Tears did well up in Gleaming's eyes, and true to her word, Cadance pulled back a little, beginning to thrust shallowly and quickly inside Gleaming's pussy. But Twilight didn't let Gleaming pull back – she held Gleaming's horn tight as she trembled in place, the twin bulges of her balls pressed against Gleaming's chin as her cock throbbed again and again.

For Gleaming, there was no thought of swallowing – it wasn't necessary. Twilight pumped her load of cum down so powerfully that it flowed all on its own. All Gleaming had to do was to sit there and endure it as her stomach was pumped full of her sister's magical spunk. Or maybe ... enjoy it? A shudder ran through Gleaming's body, all the way from her strained throat, down her back, and down until it made her pussy squeeze around Cadance's cock a little extra. There was no way she could fool herself. She was enjoying this!

As Twilight's orgasm began to fade, Cadance shifted her grip upwards a little to Gleaming's hips and used that grip to pull her back, plunging all the way in.

Gleaming moaned around Twilight's softening cock as it slipped up through her throat. Her wife's cock felt so massive, so hot inside her. And Cadance kept giving it to her, harder and deeper, even as Twilight pulled the rest of her cock out.

Twilight laid her now-limp, but still long and heavy, cock right on top of Gleaming's face, smearing her with remnants of cum and gooey saliva from deep inside Gleaming's throat. But then Twilight's horn glowed again. For a moment, Twilight's cock vanished. Everything that had been stuck to it immediately fell down onto Gleaming's face, splattering down and leaving an indelible mark – a scent that would claim Gleaming as Twilight's from then on ... provided Cadance didn't have anything to say about that.

Of course, Cadance did have something to say ... or rather, something to do. She slammed her cock deeply inside Gleaming's pussy again and again, harder and more fervently every time. And even as Cadance's cock moved so quickly inside her, Gleaming could feel her wife's flare growing. Cadance was getting close now...

Twilight renewed her spell, bringing a brand-new and refreshed cock into being in front of Gleaming's face. Since Gleaming already had her mouth open and tongue hanging out, Twilight simply ran her already-hard cock along Gleaming's tongue ... and Gleaming soon took up the task, licking her sister's cock again.

Before Gleaming could go back to fully taking Twilight's cock in her mouth again, though, Cadance completely lost control. Her thrusts lost all rhythm, her grip around Gleaming's hips spasmed, and a moment later she slid her cock as deep inside Gleaming as it could possibly go.

The idea that she might actually get pregnant from this only entered Gleaming's mind as she felt her wife's flare spreading open the entrance to her womb.

At that point, though, she didn't even care. She let her eyes drift closed and her tongue lie motionless against Twilight's cock as she felt the thick spurts of warmth begin to fill her deep inside. It was an entirely new feeling, quickly overwhelming everything she'd felt before, and the way Cadance's pulsing throbs stretched and moved her inner walls was quickly driving her toward... toward...

Gleaming's whole body arched backward as she cried out, her pussy spasming around her wife's cock, driven to orgasm by the strong pulses of heat shooting into her. Every pulse seemed to reverberate through Gleaming's whole body, bouncing back and forth through her and making her shake and jitter as Cadance dumped her load inside.

“Hmm...” Twilight ran her fingers through Gleaming's mane as Cadance pulled out, trailing a stream of sticky cum behind in Gleaming's still-spasming pussy. “Cadance, do you think it's possible for this combination of spells to get Gleaming pregnant?”

Cadance shrugged, wiping her cock on Gleaming's ass. “I don't know... But there's only one way to find out.” She leaned up close to Gleaming's ear. “And if you do get pregnant, I'm going to keep you as a mare at least until you give birth. You're going to be my little broodmare.”

Gleaming moaned, both from her wife's words and from the last few pulses of her own orgasm.

Twilight stroked her fresh-and-ready cock in front of Gleaming's face. “Honestly, that's kind of a turn-on. I think I want to try that pussy for myself. Is that okay, Cadance?”

Cadance nodded.

Magic gripped Gleaming again, spinning her around to face her wife. Twilight rubbed Gleaming's ass, her pussy, and after a few moments ventured a couple fingers inside Gleaming. When she took her fingers back out, they were coated in a mix of Gleaming's juices and Cadance's cum. “Such a nice pussy,” Twilight said. “From now on, I'm going to take it whenever I want – your pussy will never have to go empty again.”

Gleaming heard that, but it didn't register very well. What held most of her attention was the huge pink cock hanging in front of her face. It was the first time she'd seen her wife's cock.

Cadance took hold of her own cock and waved it in front of Gleaming's face. “I think I could use a little clean-up, dear.”

Even as Twilight finger-fucked Gleaming's pussy, Gleaming dutifully leaned forward and planted a long, slow lick up the dripping length of Cadance's cock. The taste of Cadance's cum and her own juices flooded her mouth; it was even muskier than what little bit Twilight had dribbled onto her tongue on the way out. But it did something inside Gleaming. Her tail rose even higher over her back, and without thinking about it, she went back up to the tip of her wife's cock and took it into her mouth. She could feel it beginning to harden again as she slipped it willingly down her throat, and she looked up at her wife with the most grateful, lusty look she'd ever given.

As she looked up at her wife with her wife's cock deep in her mouth, though, Gleaming's eyes suddenly opened wide. She'd felt the tip of Twilight's cock rubbing up against her pussy.

Twilight slid just barely inside, her thick tip easily plopping in, and she spanked Gleaming's ass, making a resounding clap that echoed through Cadance's guest suite.

Gleaming moaned. She could feel that red hand print on her ass, each and every finger of it. She moaned even more – she couldn't help herself – as Twilight pushed into her. That long, slightly curved purple cock nestled right into Gleaming's pussy as if that's where it was always meant to be, filling her perfectly.

As Twilight started fucking her in earnest, Gleaming took it upon herself to worship her wife's quickly hardening cock. When Cadance grew fully hard again and her shaft thickened fully, it became too much to bear. Gleaming had to pull her mouth off of it or she wouldn’t be able to breathe at all. Cadance's cock was a fair bit bigger than Twilight's, or at least thicker, if maybe not quite so long. But that didn't stop Gleaming from slathering her lips and tongue all over it, letting the rhythm of Twilight's thrusts from behind dictate the way she moved back and forth across the curve of her wife's thick pink cock.

Just as Twilight's thrusts became a bit more labored, a bit less under control, Cadance leaned over Gleaming's back and set a hand on Twilight's shoulder. “Twilight,” she said, “I know how special Gleaming is to you. And since her anal virginity is special as well, I'd like for you to have it.”

Gleaming's eyes went wide, and she paused her efforts on her wife's cock for a moment. Her what now? Was Cadance just doing this to make sure any pregnancy would be hers?

Twilight gripped Cadance's hand. “Aww... Thank you!” In one long motion, she pulled her cock out of Gleaming's pussy and lined it up just a bit higher.

“Here, let me get her ready. I have a special 'Princess of Love' spell just for this occasion...” Cadance's horn glowed, and the next moment, Gleaming felt the tingle of magic shoot up her ass: cleaning her, freshening her, and leaving her all slippery inside.

Gleaming looked up at both of them. “Um, ladies, maybe we should—”

Cadance shoved the tip of her cock in Gleaming's mouth. “Not now, Honey.”

With her mouth now full, Gleaming couldn't do anything to protest the pressure she felt building around her asshole.

It increased and increased, until Gleaming thought she'd split in two, and then pop, Twilight's cock slid inside her, where nothing had ever gone before. Gleaming's eyes shot open wide, and she moaned loudly around the tip of Cadance's cock.

And that was just the tip. There was more to come – much more. But Twilight's relatively slender cock just slid in so perfectly, so easily. Every little nudge forward just slipped right in without protest. After a little while, Gleaming even began willingly working over her wife's cock again, coming to terms with the ever-increasing pressure from behind.

Until Twilight reached her medial ring. While it had been only noticeable enough to give an extra bit of pleasure when it went into Gleaming's pussy, the thick bulge of Twilight's medial ring felt far more substantial where it was trying to go now. Gleaming couldn't help but give little panting breaths every time Twilight tried to push it in.

“Keep going,” Cadance said. “I love the sounds she makes when you do that.”

With one extra-strong thrust, Twilight popped her medial ring through Gleaming's asshole as well, easily sliding the rest of the way in until she was fully hilted, her balls kissing against Gleaming's soaked pussy.

Gleaming pressed her wife's cock against her face, holding on for dear life as Twilight tried out a few experimental thrusts. “Wow ... she's so tight,” her sister said, spanking her ass again and making her moan against the cock between her lips.

Every time Twilight's balls bumped against Gleaming's pussy, a little shudder went through her. Her mind was swimming in a sea of sex now, the sensations overwhelming her and nearly making her forget where she even was. As much as she was trying to pleasure her wife through a bit of fellatio, she was also leaning on that firm, strong cock as kind of an anchor to keep her from drifting away to completely mindless abandon.

“It's kind of a shame for her pussy to go empty, though, don't you think?” Twilight pulled on Gleaming's tail a little, accentuating her point.

Cadance pulled her cock away from Gleaming's mouth. “I think I might be able to help with that, if you could just... Yes, just like that.”

Twilight reached underneath Gleaming and pulled her up. With the assistance of a little magic, she ended up held in the air in front of Twilight, with Twilight standing up behind her, still buried deep inside her ass. Gleaming's legs were stretched wide and held high in front of her, leaving her whole body exposed to Cadance, who stood up in front of her, coming closer.

Cadance pressed herself against the front of Gleaming's body, but didn't slip inside her just yet. She let her warm pink cock smush between their two bellies as she reached up and wiped a bit of something gooey from Gleaming's cheek with her thumb. Pressing her thumb into Gleaming's mouth to get it cleaned off, she grabbed one of Gleaming's tits with the other hand. “How's it taste, Gleaming? Are you ready to get another load from your wife?”

Gleaming nodded slightly, Cadance's thumb still in her mouth.

Pulling her thumb out of Gleaming's mouth, Cadance used that hand and a long stretch of her hips to line her tip back up with Gleaming's pussy. “I am so getting you pregnant.” With one savage thrust, she pressed her entire cock back inside, once more claiming Gleaming for herself, even as a bit of her previous cream pie leaked out around the base of her cock.

Twilight's magic released Gleaming now, and she fell downward just a little, sliding down on both of the cocks inside her until each of them were as deep as they could possibly go. It was a much tighter fit this time, stretching more than anything Gleaming had ever attempted before. She couldn’t even begin to imagine how it would feel once—

Twilight was the first to move, with just little rocking motions of her hips. Gleaming could feel every last contour of her cock inside ... and apparently, so could Cadance.

“Oh wow,” Cadance said. “I can feel you inside, Twilight – that's your medial ring, isn't it?”

Twilight gave an extra-hard, jabbing thrust. “Come on. I need all the help I can get if we're going to leave this slut a drooling mess.”

Once Cadance began moving inside her as well, Gleaming found herself rocking back and forth between the two alicorns. Every motion forward pressed her deeper on her wife's cock and let Twilight pull out a little, and every motion backward did the reverse, plunging her all the way down on Twilight's lengthy cock while letting Cadance get ready for another push. There was no respite, no lull in the pleasure coursing through her; she let her tongue loll and bleated out moans almost as continuous as the unending stimulation she was getting from both sides. Even her breasts tingled as they rubbed against Cadance's, and her hands – still bound behind her back – rubbed up and down on Twilight's smooth belly fur.

Things only became more intense for her as she felt them – both of them – beginning to flare deep inside her ass and her pussy.

“Are you ready, Gleaming?” Cadance said between strained breaths. “This one's getting you pregnant for sure. Then you'll be my broodmare forever.”

Twilight's lips tickled the side of Gleaming's ear as she whispered from behind, “Cadance might get this one, but I'm giving you your next baby – and in the meantime, I'm going to fill your slutty ass until you can’t hold another drop.”

Gleaming couldn't hold back any longer. She came, and came hard. Her pussy and her ass convulsed around the two pillars of horse cock inside her. Those twin shafts – for a bright and beautiful moment – defined her entire existence. Nothing else mattered but the heat and the firm, undulating pressure she felt from both in front and behind. Wave after wave of orgasmic pleasure washed through her, wiping her mind blank.

Just as Gleaming's orgasm began to subside, both Twilight's and Cadance's rushed in to take its place ... or perhaps to renew it, because the feeling of both cocks inside her throbbing and pulsing in their staccato rhythm threw Gleaming into another wild spiral of orgasmic bliss. Her head spun and her whole body burned like fire. There was just so much! Even after she was completely full and every spurt from Cadance or Twilight just spilled out onto the floor, both of them kept going, as if they each had a limitless supply.

Of course, they didn't. Eventually, they were only draining their last few spurts into her ... but they both stayed hilted all the way inside her, making sure every drop went as deep as possible.

Cadance pulled out first, stepping out of the way just in time to avoid a small deluge of cum. Twilight then lifted Gleaming off of her cock, Gleaming's tight asshole pulling on her and stretching out her length just slightly before letting go with another splatter of cum onto Gleaming's thighs and the floor.

Twilight's magic gently lowered Gleaming down to the ground ... where she immediately collapsed into the small puddle of cum. She was little more than a quivering puddle herself.

Still, when her arms were magically untied, Gleaming got up to her knees and opened her mouth. With one hand, she held her own tits up toward them, and with the other she touched her own belly. Her body hadn't been lying – her belly felt full now, as if she'd just eaten a huge feast. In a way, she had.

Cadance and Twilight easily took the hint, stepping up to her and presenting their now-hanging cocks for cleaning.

Gleaming couldn't take the time to take either of them entirely in her mouth. Instead, as the two alicorns held their cocks close together, Gleaming licked her way up and down both of them at the same time, licking up all the precious traces of cum and ... other things. As Gleaming paid the dripping tip of Cadance's cock a little extra attention, Twilight wiped the tip of her own on Gleaming's tits, laying a few little beads of additional whiteness across the huge white bulges. And all the while, a slow flow of cum streamed from Gleaming's pussy and asshole, straight into the puddle on the floor, though some of it managed to stain the fur on her thighs.

Somehow, without any words between the three of them, all three knew just what to do. Cadance and Twilight carried Gleaming to the bedroom, laying her on the bed and then lying down next to her on either side for some well-deserved cuddling and relaxation. Twilight's horn flashed, and both alicorns' cocks vanished, replaced by their more familiar pussies. Cadance didn't cancel the gender-flipping spell, though. Of course; she couldn't. And even in her impaired state, Gleaming was doubting whether or not Cadance even wanted to.

Gleaming had been completely wiped out and was ready to drift off into a well-earned nap, but Cadance and Twilight both seemed to be a little more active in their cuddling. Their hands wandered – not only over Gleaming's body, but each other's as well.

“Do you think we could do this again sometime?” Twilight asked. It wasn't clear who she was speaking to.

Cadance smiled and grabbed a couple nice handfuls of Gleaming's tits. “I'll tell you what... You teach me that endowment spell, and I'll teach you the gender-flipping spell. Then we'll both be able to have Gleaming anytime we want.”

“Mmm...” Twilight reached down and cupped Gleaming's leaky pussy. “I can't wait to fill you up in the morning.”

Gleaming scrunched down, as if trying do disappear into the softness of the bed. “Don't I get a say in any of this?”

“No, no you don't.” Cadance grinned knowingly at Gleaming. “Because we both know you like it that way.”

“Mm-hm,” Twilight added as she nuzzled Gleaming's mane.

“But I—”

Before Gleaming could even start her very reasonable argument, Cadance levitated up the strap-on she'd been about to use earlier. She unceremoniously shoved it into Gleaming's mouth and down her throat, fastening the straps of it backwards around Gleaming's head so she couldn’t spit it out. She raised her hands toward the straps, but for some reason her fingers just fumbled along the latches ... more magic.

Gleaming's throat bulged out slightly, but Cadance came up close, putting her cheek next to her wife's nose. “Ah, yes, good,” she said after waiting quietly for a moment. “You can still breathe. Let’s just give you a touch of magic to be sure.”

The strap-on wasn't as thick as either of their cocks had been, and after the ramming Gleaming's throat had already gotten, she found it actually wasn't too difficult to keep it in there, but when Cadance’s spell washed over her, she could breathe almost as easily as if there was nothing at all. Why couldn't they have done that earlier?

Cadance smiled at her work. “There. Now, maybe if you wake me up very nicely, I'll let you be a stallion again for a day or two.” She looked over Gleaming's tits at Twilight. “In the meantime, Twilight, I wouldn’t want poor Gleaming's pussy to be empty the whole time. I think that lovely cock of yours will always have a welcome home right...” She slipped a finger inside Gleaming's pussy. “... here.”

Twilight's horn flashed, and she rolled Gleaming onto her side, facing toward her, and the moment Cadance pulled her finger out, Twilight's again-renewed cock slid perfectly inside.

None of them moved much, though. Gleaming was already drifting off, no longer able to keep awake, and the other two weren't much better off. Gleaming was simply able to fall into sleep with the comforting, warm presences of her wife and her sister not only cuddling all around her, but inside her as well. Everything was just as it should be. The last thing she felt before falling asleep was both Twilight and Cadance kissing each side of her cheeks as they groped her one last time.
