As she had done every morning of her reign, Princess Celestia raised the sun at the appropriate hour. Her joy in this task magnified with her sister at her side, who lowered the moon in concert with the sun rising. With deep satisfaction Celestia felt the solar body start on its measured course and with a soft smile turned to Luna.

“I’m going to miss that,” Celestia said, to her sister and the group of friends and hangers-on who had come to watch. One delicate eyebrow rose as she noticed that one of her friends was wearing a close silver collar with a chain leash that was held firmly in Luna’s grasp. Luna watched Celestia’s gaze travel from Valiente’s collar, along the shimmering leash, to herself, and began to blush furiously.

“Valiente had an idea… that is she… I,” Luna sputtered trying to explain.

“Please forgive our Mistress, Princess Celestia,” Rarity said, her cultured and professional voice proclaiming that she was the one in charge of the body she shared with her mind sister. “Valiente came up with an idea to help reduce the stresses of the ownership bond between herself and Twilight. Last night, with my approval, she enacted the plan.”

“Did it work?” Twilight Sparkle asked, coming around her mentor with hesitant steps. The smaller purple alicorn looked at Luna for a moment, then away quickly expecting the power of the ownership bond to drive her to her hooves once more.

“Twilight?” Celestia asked, looking at her former pupil with concern. “How are you feeling?”

“I think,” Twilight said, still standing, “I think I’m okay. I think it worked!” Celestia and Twilight shared a happy hug as the others looked on. Mouse, the loyal Moon Dog, was breathing a particularly deep sigh of relief.

“Yes, and all it took was me being rutted to the point where I can barely stand,” Rarity murmured to no one in particular.

Oh, don’t be like that, Valiente said, her laughter bubbling out of the cage that held her in its thrall. You loved it as much as I did. Our Mistress was so strong, so masterfull…

“So vigorous you mean,” Rarity said, rolling her eyes. “My legs are as stiff as starched cotton and my plot is so sore I can’t even sit properly.”

“What in tarnation?” Applejack exclaimed, and Rarity realized she had spoken the last sentence aloud.

“Oh dear,” Rarity said, blushing. “That was supposed to be my inside voice. I’m so sorry everypony.” Everypony on the balcony chucked at Rarity’s embarrassment.

“Rarity,” Luna said, in mock severity as she drew the leash taut. “A good chattel knows when to… damn.”

Rarity looked over her shoulder to see that Twilight Sparkle was again prostrating herself to Luna. Forelegs flat to the ground, haunches high, marehood exposed, and tail flagging, in the classic pose of a slavemare offering herself for whatever use her owner deemed fit. A deep sigh came from Luna.

“It was a good try, Rarity,” Luna said, waving Mouse in and facing Twilight directly. “Rise, Twilight. You have done nothing wrong.”

“Sorry Princess Luna,” Twilight said, getting back up with Mouse's assistance. “As soon as I heard that tone of voice, there was nothing I could do.”

“Think nothing of it, Twilight,” Luna said. Whatever else Luna was going to say was drowned out by the sound of a trumpet from a lookout stationed up at the top of one of the Canterlot Castle’s towers.

“Oh, that big meany pants Chrysalis is here,” Pinkie Pie said, pulling out a telescope herself from somewhere and looking to the horizon. “Wow, she’s got a whooooole lot of changelings with her too.”

“Luna, we haven’t much time, come here,” Celestia said, and when Luna complied she touched her horn to that of her sister and ignited her magic. “I, Celestia, Sol Invictus and Princess of Equestria do hereby pass my title, power and authority to my sister, Luna, Noctis Regina Filia, and Princess of Equestria. She is to hold these powers in trust for me until she deems it safe for me to take up my mantle again.”

“I, Luna, Noctis Regina Filia, accept this charge and vow to discharge the responsibility given to the best of my ability,” Luna said, in pronouncement, and in that moment the Princess of the Night seemed to become more than she had been before. Celestia stepped back and bowed her head to her sister, who fairly radiated power.

“With permission, Your Majesty,” Celestia said, keeping her words formal. “I shall withdraw so that I may keep my appointment with the changeling queen.”

“Light go with you,” Luna said, hugging her sister. Celestia turned, paused, and then hurried away with a couple of guards trying to keep up with her.

“What the hay just happened?” Rainbow Dash asked, looking askance. “Should we go after her?”

“No,” Luna said, and her voice held an extra depth to it that none of them had heard before. “She goes to prepare herself for her seven days as Chrysalis’ plaything. It will likely not be easy for her, and there are good odds that Chrysalis will break my sister. Which is why she invested me with her titles and power.”

“What does that mean?” Fluttershy asked, shy curiosity flaring.

“It means that for at least the next seven days Equestria is a monarchy instead of a diarchy,” Twilight Sparkle said. “Instead of two princesses, we have one.”

“How long do you think we are going to have to wait, Rosin?” Chrysalis asked her general. “Think we’re going to have to try to invade again?”

“A head-on assault, against a prepared position like Canterlot?” the battle scarred veteran said. “It would be a slaughter for the ages.”

“That’s the spirit!” Chrysalis said, thumping her battle commander on the back.

“No, Your Majesty,” Rosin said, stepping back to where he had been standing before the blow. “It would be our slaughter. Bards would sing of the insanity of the Changelings for a thousand years.”

“Nothing like being remembered, eh?” Chrysalis asked rhetorically, a broad smile on her face. Rosin looked at his queen and wondered if she had gone mad at long last.

“Being remembered would be a fine thing, your Majesty,” Rosin said, trying not to look like he was backing away from his queen. “But being remembered and being alive at the same time is a better thing.”

“Are all the decoy troops in place?” Chrysalis asked, watching the distant battlements for any sign of movement.

“Yes, my Queen,” Rosin said, nodding. “As far as anypony can tell we have 30,000 troops with us.”

“And we actually have?” Chrysalis asked, cocking an eyebrow at him.

“A little over 3,000,” Rosin said, with a grimace.

“It will be enough, to deter any pursuit,” Chrysalis said, scoffing at the bit of sweat she saw on her general’s shell. “It WILL be enough. Celestia is a mare of her word, after all. She will be here and then we are going to get to know each other very well indeed. “

“You’re right, my Queen,” Rosin said, peering through a telescope. “There appears to be movement at the front gate.”

“Of course I’m right,” Chrysalis said. “I’m always right. Have the crates holding Celestia’s tack brought up. We have to make sure the princess is dressed for the occasion.”

“You didn’t have to come with me, Twilight,” Celestia said, as the great gates of Canterlot closed behind them. “One of the others, or even one of the guards could have come with me.”

“I wanted to come,” Twilight said, as the two alicorns made their way toward the waiting horde. “Besides, I know Mi… your sister, can’t come and as her prop— friend I should come in her place.”

“I’m sorry I ever sent you on that mission to the Badlands,” Celestia said, laying an ivory wing over her former student. “You paid the price for a mistake I made, and you’re still paying it.”

“To save a friend, it was a price worth paying,” Twilight said, a half-smile on her lips. “And being owned isn’t all that bad a thing, especially when the owner is someone like your sister.”

“Luna is a good pony, thanks to you,” Celestia said, as the road began to rise to the small hill where Chrysalis waited with her troops. “I know she’ll do right by you.”

“Thank you, Princess,” Twilight said, hugging her mentor. “And it really is getting better. Every time another pony gives me a copy of their memories of me, it’s like I get a little bit of myself back.”

“In that case,” Celestia said, stopping a full hundred yards from where Chrysalis waited. “I was going to wait to do this until I got back, but I think now is the time."

Celestia lit her horn, and every changeling on the nearby ridge grabbed for their weapons, but the solar alicorn did not send her power at any of them. Instead, a band of shimmering golden light stretched out and wrapped itself around the neck of the lavender alicorn, compressing and tightening until it lay full against the collar fused around Twilight’s throat. Another row of engraving appeared on the steel band, this one so thick with details as to be almost a solid line. Memories started to flood into Twilight’s mind. Her magic running wild at her initial exam, meetings with the Princess, her studies, her becoming an alicorn. Each memory filled with love, pride and the joy in seeing a young pony come into her own.

Then, a more sinister memory demanded attention. Twilight was suddenly bombarded by a series of images. A guarded and hidden vault, ponies sworn to secrecy, weapons and plans waiting in place for the dreaded day they might be used. Most of all, a particular vault containing a pair of works of master craftsponyship. Two exquisite bridles that were deadly weapons against the two mightiest ponies of all.

In Twilight’s minds eye she saw one of the bridles rise up and hover before her. Dyed white unicorn hide, set with sunstones, and of breathtaking beauty. The bridle was not only made to capture the wearer, but to enhance their allure as well. Across the brow band of the bridle, in gold thread, were the words “Conquered Sun.” Twilight remembered now. This was one of the memories she had made sure she had removed from herself. Celestia had kept the bridle so that there would always be a way to stop her if she ran amok, and it was as dangerous to Celestia as it was lovely.

“Yes Twilight,” Celestia said, softly. “Remember. If she manages to change me, you know what to do.”

“Princess Celestia… “Twilight said, her voice trailing off. She knew Celestia was right. A good ruler protected her subjects from all dangers, including herself.

“Just go,” Celestia said, hugging Twilight one more time. “Go, and know that I love you, my ever faithful Twilight.” The two shared the embrace for a few more seconds, before Celestia broke it off and began to step resolutely forward.

“I love you too… Celestia,” Twilight said, under her breath as she followed the command she had been given and turned back toward Canterlot.

“Hello Celestia,” Chrysalis said, a minute later as the white alicorn came up to stand before her. “Or should I call you ‘Toy’?”

“I’m here to honour our agreement, Chrysalis,” Celestia said, frowning. “As part of that, you can name me whatever you like. For the next seven days.”

“I’m a little disappointed that you came alone,” Chrysalis said, smirking as she motioned her changelings in to surround the white alicorn. “I was so looking forward to tasting Double Snack again.”

“You are never getting close to Rarity again, not if I ever have anything to say about it,” Celestia declared, and then sighed as she saw the changelings closing on her with ropes, straps and chains. “How do you want me?”

“Writhing at my hooves,” Chrysalis said, before shouting, “NOW!”

At the command of their queen the changelings leaped upon the ivory alicorn, who could have made them pay dearly for their affront had she chosen combat. Straps were cinched down, ropes knotted and chains locked in place, as with a flurry of motion Celestia was borne down to the ground and reduced to being a helpless prisoner.

“Up you get, Toy,” Chrysalis said, pulling Celestia back up with a leash. “Let’s see what you look like.”

Celestia stood, and Chrysalis loosened off the leash enough to let her captive breathe. The body of the white alicorn was now crisscrossed with gleaming, black rubber straps that had been cinched down tight enough to dig into Celestia's flesh.

Down the line of her back ran a broad anchoring strap from which ran other lines that looped down and around her barrel. One behind her forelegs, one in front of her hips and another tight against her belly. All three were anchored to another strap that ran down from her throat and along her underside, before rising up between her thighs and cleaving her sex in two before attaching to a collar for her tail that held it high and upright.

Attached to the straps was a shining web of fine chains, that draped over Celestia’s body like a blanket. The chains were festooned with bells, so that even the slightest twitch was a symphony of sound, and their tiny links seemed to grab at the individual hairs on Celestia’s coat, like a thousand tiny paws that grabbed and pulled at her. The last touches were the golden hobbles that were locked to her hooves and chained together to limit her stride to a walk.

“What, no bridle Chrysalis?” Celestia asked, mocking the changeling who was her acknowledged owner for the next week. “Nothing to block my magic?”

“No need, just yet” Chrysalis laughed in reply. “All this is just for the benefit of your subjects watching from the castle walls, and besides, I know that your word binds you tighter than any rope or chain ever could. Now hold still, there are still a few items left to add to your tack.”

From a box, Chrysalis pulled out a pair of large, thick cylinders. They were black in colour and covered with small nubs, and the green glow of changeling magic pulsed from their bases. Celestia’s eyes widened as she saw the size of the dildos.

“Really, Chrysalis?” Celestia asked, trying and failing to keep a slight quaver from her voice. “Did you have to start with this sort of thing right away?”

“What and deny myself the pleasure?” Chrysalis asked, as she caressed the perfect folds of her alicorn. The changeling seemed to know just where to touch Celestia, her touch sliding along the inner lips, gently rubbing the soft nub at their apex, and dipping deep to just along the entrance to the alicorn’s dampening passage.

Celestia tried to hold back the flush of warmth she felt, but she knew there was no point in attempting to stop the sensations the changeling was stoking in her. Freed from the restraints of order and discipline Celestia’s pussy winked itself around the dark hoof in it.

“I’m so glad you’re enjoying yourself, Toy,” Chrysalis purred, and then pulling aside the anchor strap slid home the first dildo down through Celestia’s entire passage. As the tip of the device bumped up against her cervix, Chrysalis’ new toy filled the small valley with the whinney of her pleasure.

“Where… did you get something like that?” Celestia gasped, quivering around the shaft filling her.

“How soon we forget, my Toy,” Chrysalis said, rubbing the second shaft around the base of the first and lubricating it with the juices that were beginning to flow. “I had you in a pod. I know all your measurements. Inside and out.” Chrysalis touched the base of the dildo with her magic and it flared to life inside Celestia, who sucked in a snorting breath.

“I can feel it rubbing and pushing against me inside,” Celestia gasped out, stomping a hoof and setting her chains and bells ringing. “What is it doing to me?”

“What is it doing to me… Mistress?” Chrysalis reminded Celestia, touching the tip of the second shaft to her rosebud. “Remember your oath.”

“What is it doing to me, Mistress?” Celestia asked again, and she looked back to see what Chrysalis was about to do with the second shaft. “Please Mistress, that won’t fit. Not with the other one there.”

“All your measurements,” Chrysalis repeated, and slowly worked the now well lubricated dildo in past the royal rosebud, sinking its nubbed surface deep into Celestia. The now twinned shafts rubbed the narrow wall of flesh between them, and Celestia came in a flash of light and a thunderous whinney of pleasure that echoed off of Mount Canter itself. A moment later there was a “pop” of air and a furious pink alicorn materialized twenty feet above the unfolding scene.

“Stop that, right now Chrysalis!” Princess Cadance roared, her entire body aglow with her fury and power. ”Or I swear, all that will be left of you is a burn mark on the ground.”

“Hello again, Mine,” Chrysalis said, unperturbed. “Come to kneel before me again, have you? You can be a matched set with Toy here.”

“Let her go, now!” Cadance demanded, shooting a blast of magic to scorch the earth in front of Chrysalis. “I mean it!”

“I believe you mean it. One moment, please,” Chrysalis said, stepping around to lift up Celestia’s chin and looking her in the face. “Is this how you intend to keep your promise to me, Toy?” Celestia, still panting in recovery from her orgasm, shook her head free from Chrysalis to look up at Cadance.

“... Gave my word, Cadance,” the white alicorn panted out. “Whatever she wants to do… seven days.”

“But, she’s… “ Cadance said, magic and fury dissipating as her words trailed off, and those present could barely hear her say, “She’s doing to you what she did to me.”

“Indeed I am. I still remember our time together in the Crystal Caves under Canterlot with great fondness,” Chrysalis said, a smirk of pure desire coming to her face. “I am not without some mercy, Mine. Kneel before me again, Cadance. Take on the name ‘Mine’ again for five days, and I will take two days off of Toy’s time with me.”

“Don’t, Cadance,” Celestia said, bringing herself back under control. “Luna and Twilight need you. I can handle anything she can do to me.”

“I’m sure you think you can, my lovely Toy,” Chrysalis purred, stroking the side of Celestia’s muzzle. “I look forward to seeing if you can’t. Well, Cadance, what will it be? Submissive pleasure kneeling before me again, going back to boring Canterlot to help your sister-in-law, or making Celestia into an oath breaker?”

Cadance looked back and forth between the two, and she could see that Chrysalis was enjoying her indecision. Gritting her teeth she said, “Fine, I’ll go. But if Celestia comes back in any way less than how she left you will answer to me.”

“Boring,” Chrysalis said, her voice mocking. “If all you are going to do is make idle threats than you can keep your mouth shut. Although, you can certainly stick around to watch. Who knows, you might learn something.” Cadance disappeared with a “pop” of imploding air as she teleported back to Canterlot.

“A shame, I have a nice chariot to harness you to later, Toy, and a pair of alicorns would have been nice,” Chrysalis said, smiling. “I still have all her old tack too. Oh well, let’s be on our way.”

Putting actions to words she clipped a lead rope to Celestia’s harness and gave a tug to urge her new possession forward. Celestia took two steps forward and stopped, gasping as the muscles in her belly and hips flexed themselves against the intruders.

“What are those things doing in me, and why can’t I push them out?” Celestia said, looking at Chrysalis in accusation. “What are you doing to me?”

“For now, making you feel,” Chrysalis said, pouring her words like honey into the alicorn’s ear. “Making you endure the sensation of a couple of hard cocks, buried deep inside of you. Stroking you, rubbing you, twisting away as they penetrate all your defenses. No matter what you do, they’ll keep driving you into a frenzy of pleasure with every step you take. Until all you can think about is the need to cum, and cum again, as those cocks learn what drives you mad.”

“What are you planning, Chrysalis?” Celestia said, shuddering as the nubs on the magical rods in her reached out to lick at the velvet walls around them.

“For now, I’m planning on seeing how many orgasms I can draw out of you,” Chrysalis said, tugging on the lead. “Now, let’s get going, we have quite a ways to go yet.”

It was one of the most tortuous walks of Celestia’s long life. With every step she took, she was aware of her filled sex and ass. That would have been enough on its own to drive a mare wild, but as Chrysalis had said, the magical shafts she had jammed into Celestia were more than a just pair of simple dildos.

Every step she took they would slide back and forth, alternating in depth and speed. The nubs would vibrate, sometimes moving on their own to lick out at Celestia’s most delicate spots. Trying to walk with her core being kept on the near edge of orgasm was torture as her body kept trying to clench around and milk the dildos. So, when something actually splashed against her inner walls she exploded into helpless orgasm.

“Enjoyed that did you?” Chrysalis asked, holding Celestia close. “That was only the first one.”

“How?” Celestia garbled out, before steadying herself. “How did it do that? How did it know to do that?””

“That’s the beauty of these little devices,” Chrysalis laughed, slackening off the lead a touch. “As they learn what drives you wild, they can keep you on edge or they can give you the most mind-blowing orgasm of your life. Given enough time, I’ll be able to use them to make you cum at any moment with just a touch of my magic. Now, come along, Toy. We still have quite aways to go.”

Celestia got to her hooves and started walking again behind the changeling who held her leash. As they travelled on, a pattern began to develop. Celestia would walk for awhile, the driving shafts slowly building her up to a sexual peak, and then they would shove her over the edge, into another shuddering orgasm.

The gap between orgasms began to grow shorter and shorter, proving the truth of Chrysalis’ words that the magical constructs were learning what made Tia tick. After apparent hours of walking, with bursts of orgasms that sent her crashing down to the ground, Celestia suffered a climax from which she just could not get up from. She lay, helpless on the ground as spasms and shudders coursed along the length of her body. To her surprise, Chrysalis sat on the ground beside her, pillowing Celestia head in her own lap.

“Water,” Celestia croaked, futilely trying to bring calm to her body. “Please.”

“As soon as something else is done, Toy,” Chrysalis said, locking eyes with the drones who were closest to them. “Restrain her.” Changelings ran to do her bidding, fastening Celestia hooves together and holding her down.

“What are you do—urk,” Celestia said, as a bit was driven to her mouth, trapping her tongue beneath a rounded metal plate coming off it.

“That will be enough talking from you, Toy,” Chrysalis said, buckling the strap of the gag tight. Then a drone passed something to Chrysalis that made Celestia buck and thrash. If Celestia was fresh, she could have bucked the changelings off of her. If her mind hadn’t been mazed from countless orgasms she could have brought forth her magic and destroyed her foes in an instant of fire and destruction. Chrysalis had planned well though, and Celestia was unable to stop a bridle from being looped over her head and down onto her horn.

Celestia could feel the moment the magic blocking sheath attached to the bridle settled over her horn and cut off her connection to magic. The straps were tightened down, and Celestia heard the snaps of locks sliding home, locking the controlling device to her. Celestia thought Chrysalis was done until a needle pointed knife appeared in Chrysalis’ hoof. Stabbing quickly, Chrysalis punctured her own carapace drawing forth a trickle of ichor.

Celestia then felt a stinging sensation as the knife cut a line on her neck, and she could feel a trickle of her blood run down to one of the bridle straps. Chrysalis pressed her oozing hoof to the wound and said, “From this day forth I am your Mistress. From this day, until the day I free you or I pass the bond to another. I name thee, Toy, bound to Chrysalis, Queen of the Changelings.”

By the Light, Celestia thought, as she remembered the report that gave the words of Raarg, when he had bound Rarity to himself. I’ve been bridled.
