The train from Ponyville arrived just as Celestia was bringing down the sun for the day and as the train came to a stop the group of friends, and their escort all rose from their seats; save Rarity, who didn’t move at all.

Rarity, dear, Valiente said to her sister, why aren’t you getting us up?

I’m sorry, Valiente, Rarity replied, but I’m afraid meeting Mouse shook me rather badly. Could you take over, at least for awhile?”

You aren’t going to hide yourself again, Rarity, Valiente said, firmly. Not after all the trouble we went through before to bring you back.

I just need to settle myself for a bit, Rarity said, trying to assure her other half.

Rarity, Valiente said, warningly. We are not going to move an inch until I’m sure you have no intention of hiding from the world again.

“Fine, Rarity said, and she moved her consciousness to a very particular spot in the mindscape she and Valiente shared. A spot Valiente recognized, as Rarity whisked aside a dust cover to reveal a very sturdy looking, pony sized cage, complete with shackles and collar on chain tethers.

You don’t have to do this, Valiente said, shocked. That cage was meant for me, not you.

How soon we forget, dear, Rarity replied, as she crawled into the cage. The shackles immediately moved, locking themselves onto Rarity’s limbs and throat. This is the cage I would have been trapped in forever, had you not decided to go against what you were meant to do. For one of the very few times in her short life Valiente was utterly speechless.

Now, Rarity said with a slight smile, let me get some rest and pull myself back together. This cage was meant to hold me, no matter how much I struggled, so you can be assured that I’m not going anywhere and that I can’t hide on you. To emphasize her point Rarity jerked a hoof a few times, demonstrating that she was inescapably bound by chains and cage both.

Very well, but only until you are ready to come out again, Valiente said, as she turned her focus outward and took control of their shared body, opening her eyes.

“Rares?” Applejack asked, looking into the face of her friend. “We’re here, ya’ll doing okay there?”

“Just fine, darling Applejack,” Valiente said, reaching up to slide a hoof along the side of the orange mare’s strong face in a gentle caress, and the earth pony responded almost instantly with a furious blush.

“Val,” Applejack said, pushing away the hoof, “you cut that nonsense out. Ah’ve told you before ah’m not the kind of pony that should turn your head.”

“Dear Applejack,” Valiente said, looking up coquettishly, “that is where you are entirely wrong and one day I hope to prove it to you, but now is not the time, is it?”

“Almost everypony’s off the train,” Applejack said, backing up a bit, “and Princess Luna’s waiting for us on the platform, but ah came back when ah noticed you hadn’t left yet.”

“Then we’d best not keep her waiting,” Valiente said, getting up from the seat.

“Where’s Rarity?” Applejack asked as the two walked up the train car’s aisle.

“The encounter with Mouse upset her even more than she let on,” Valiente said. “She asked me to handle things for awhile until she’s feeling better.”

“Okay--” Applejack began to say, before a very loud voice echoed through the wall of the train car from the outside.

“WHO HAS DARED TO PLACE THEIR COLLAR UPON YOU?” Luna’s voice demanded, in full Canterlot Voice volume.

“Oh Criminy,” Applejack said, in a low voice. “Somepony dun put the Princess’s tail in a wringer.”

“Oh dear,” Valiente said, putting two and two together and getting an upset princess. “I think I’m in a bit of trouble. Applejack, whatever happens next, please do not interfere with how my mistress decides to discipline me.”

“Say what?” Applejack said, as Valiente breezed by her and stepped out onto the train platform. Princess Luna was there, a cringing Twilight Sparkle on the ground before her. Nearby stood Mouse, who had placed himself between the two princesses and Pinkie, Fluttershy and Rainbow Dash. Two Moon Dogs also stood behind Luna, obviously guards of some sort as neither of them were interfering in the situation either.

“WHO?” Luna demanded again, fury on her face, her body poised to strike and lash out at whatever target drew her eye.

“Mistress,” Valiente said, in a meek and humble voice. “May I approach?” Luna said nothing, only giving a curt nod. Valiente walked slowly up to where Twilight Sparkle lay on the platform and then fully supplicated herself before Luna.

“Great Princess of the Night,” Valiente began formally, “my Mistress, owner of both my body and souls, I beg thee to not be wroth with thy hoofmaiden Twilight. The collar upon her throat is but a tool to aid your servant in the recovery of her memories. I, and my other half, placed the collar upon her for this purpose and not to usurp your claim on her.”

“I...ah,” Luna said, suddenly blinking and her posture relaxed into one of confusion as Valiente’s words penetrated her anger. Luna’s aggressive stance of a moment ago relaxed and her face began to shift from furious to confused. Valiente seized on that moment of confusion and pressed on.

“Please forgive me, Mistress,” Valiente said, bowing her head until the back of her neck was exposed. “Rarity and I have overstepped ourselves and we throw ourselves on your mercy. Beat us, whip us, chain us as you will, as we have earned your wrath and not gentle Twilight. Let your anger fall upon those responsible, namely myself and Rarity.”

Valiente could not see Luna’s face, bowed as her head was. She could not see Luna’s anger fully shift to confusion then chagrined realization at her loss of control. But Valiente could hear the creak of wood underhoof as Luna stepped close and she tensed herself in anticipation of a blow. Only to feel herself suddenly swept up in a hug along with Twilight, as Luna clasped them both to her chest.

“There is nothing for me to forgive,” Luna said. “Rather, it is I who must beg your forgiveness. I can only plead stress over what will happen with my sister tomorrow. Can you forgive a worried mare who wrongly lashed out at those she cares for?”

“Of course, Princess,” Twilight said, hugging back. “I should have realized this is a hard time for you and written ahead to let you know.”

“It’s okay, everypony!” Pinkie Pie shouted, jumping into the hug. “It’s just the Princess getting rid of the grumpy grumps!”

“Um, yes, as you say Pinkie,” Luna said, extricating herself from the party mare’s grip. “Shall we walk to the castle?” Everypony agreed and the now large group, made their way toward the great castle of Canterlot. Twilight and Valiente made a point of walking to either side of Luna and a pace back of her, and it grieved Luna to see their deference to her. Not as a friend, not as a princess, but once again as their Mistress and their owner. A position she had been uncomfortable with at best, even when they had relied on her for their care.

Why did I react with such anger at seeing that collar on my Twilight? Luna pondered, as she walked along. No, be honest at least with thyself. It was not anger, but unthinking rage that somepony would dare lay claim to them, to take that which is mine. Even when they needed me to hold their reins I never thought of them as mine. Friends yes, companions into danger certainly, but not as my bondmares, not as my owned chattel. Why do I feel like this now? Why did the thought of them being owned by another fill me with such rage? Luna tried to reflect more on her feelings but her thoughts were interrupted as she realized that her and her group were walking through a silent city.

“Where is everypony?” Luna asked in general, looking around. The other ponies all paused and looked around as well. Silence greeted them, and despite the deepening shadows as twilight began to transition to night, not a single light could be seen. As the seconds passed the quiet grew threatening, and the group slowly clustered into a circle around Luna, as much for her protection as to protect her.

Finally, an earth pony walked by, a lantern shining from a ring on a harness she wore. The pony was also armed with a sheathed sword also slung from the equipment harness.

“You there, my little pony,” Luna called. “Why is the city suddenly so quiet, and why do you carry a weapon?” The pony, seeing the Princess, came to a halt several feet away.

“I’m on my way to the vigil,” the mare said simply, as if the answer was obvious.

“What vigil?” Rainbow Dash asked. “What’s going on?”

“Everypony is going to the castle,” the earth mare said firmly. “We want to show Princess Celestia how much we love her and that Chrysalis won’t take her without a fight.”

“Um, lead on, please,” Luna said, and the group followed the pony. Fifteen minutes later they reached the edge of the great courtyard leading to the gates of Canterlot Castle. There, with torches, candles, lanterns and anything else that would shed light, was the assembled populace of the city. Each and everyone of them was armed, even if in some cases it was only with a wooden club. Nopony said anything. Not the crowd, nor the guards at the gate.

Luna, Twilight, Valiente and the others stood at the edge of the crowd, not saying anything or drawing attention to themselves. From somewhere, Mouse and the two guards who had come with Luna produced lights of their own, and passed extras to the rest as they all stood there in silence. Ten minutes later, the expectant crowd seemed to sigh as one, when the gates to the castle opened wide and Princess Celestia appeared in the gateway, dressed informally with neither crown nor peytral and she looked oddly naked without them.

“My dear little ponies,” she began. “Thank you for this. You have truly given me a great gift of your love and affection, but please, do not spoil it with threats of violence. What I do tomorrow is something that I have chosen to do, on behalf of a friend. Please, return to your homes and businesses with my thanks for what you have done tonight. I shall remember it for a long time to come.”

The crowd seemed to give a little sigh at that and as one, the crowd of assembled ponies knelt to the solar diarch in a show of respect. Luna’s group were the only ponies still standing and she slowly began to lead them through the crowd toward her sister. Some ponies looked at her with annoyance as she passed, until they saw who was walking by, and they bowed their head in respect as the lunar princess moved to join her sister.

“‘Tia,” Luna said, as she drew near. “I have brought Twilight and the others with me.”

“Let’s go back inside,” Celestia said to her sister, and then she raised her voice again to the crowd. “We will see each other again in the morning, my little ponies. Again, my thanks to you all. Until the morning, go in peace and friendship.” Celestia then turned and led everypony back inside the gates, which the guards closed behind them.

“Are you alright, sister?” Luna asked, as she followed Celestia back toward the castle proper. “You are without your regalia.”

“I’ve had it put in your room, Lulu,” Celestia said. “There are certain enchantments on them that you may find useful in case I don’t...” Her breath hitched for a moment. “In case I don’t come back from what Chrysalis does to me. I need to be sure...” Celestia managed to say no more as she was tackled and hugged, first by her sister, then by the other six mares present. For a solid couple of minutes the mass hug went on, and finally Celestia, bolstered by the love and friendship of her sister and the others felt able to speak again.

“Thank you for that. I admit to being a little nervous about tomorrow, and...” Celestia broke off, as she noticed Twilight’s collar for the first time. “Luna, you collared Twilight?”

“Not I,” Luna said, gesturing toward the alabaster unicorn in the pile. “Valiente and Rarity did that.”

“Why did you do that, Rarity?” Celestia asked, getting back to her feet and nuzzling Twilight as she did so.

“Rarity is taking a rest for awhile, Your Highness,” Valiente said, bowing her head. “She and I made nothing more than a way for us to give Twilight a copy of our memories of her. A way for her to know the parts of her that she has lost.” Celestia nodded in understanding.

“Valiente, to be honest,” Celestia said, as her horn began to glow in preparation for a spell, “when I first learned of your existence it worried me. I feared you might be some aberrant creation secretly bent on destroying a pony I care for.” Power flowed from Celestia’s horn to wrap around Twilight’s neck, setting the collar on the lavender pony glowing. “But since the moment we first met you have been nothing but a kind and generous pony, if maybe a little more...physical in her generosity than Rarity.”

A new, densely packed line of fresh engraving appeared on Twilight's collar, as Celestia’s memories of Twilight joined the others and she concluded saying, “With this action, you have laid to rest any worries I may still have had, thank you for doing this for Twilight. Now, enough serious talk, let’s go have some dinner.”

The group made their way into the castle proper, where a feast had been lain out in a banquet hall, featuring all of Celestia’s favorite foods and treats. Valiente, Rainbow Dash, Pinkie, Fluttershy and Applejack surged forward toward the food. It had been a long day and all of them were hungry. Only Mouse and Twilight held back with the princesses.

“Mistress, may I go eat?” Twilight asked, addressing Luna and biting her lip anxiously. Celestia shot a surprised look at her sister.

“Please Twilight,” Luna said, ears drooping sadly. “Act as you will, you are a free mare.”

“Mis...Princess,” Twilight said. “We both know that isn’t true. I thought spending some time away from you might weaken the hold you have on me, but it hasn’t. When you got mad at me on the train platform, I...” Twilight trailed off, unable to finish.

“I know, Twilight,” Luna said, and impulsively hugged the lavender alicorn again. “I would do anything to set you free from the dark magic that has bound us together and I am sorry I became angry at you today. You did nothing wrong, I was the one at fault.” Luna noticed Mouse standing protectively nearby and an idea occurred to her.

“Did she accept you as her protector as we had discussed, Mouse?” Luna asked the Moon Dog, who nodded his assent.

“Very well, Mouse,” Luna said. “From now on you are to protect her from me as well. If I begin to act toward Twilight as her owner and not as her friend you are to place yourself between us. To keep both of us safe.” Mouse nodded and slowly drew Twilight away toward the food. The moment they were out of earshot Celestia rounded on her sister.

“Luna, just what in Tartarus was all that about?” Celestia quietly demanded. “Even when she was Tabula Rasa you kept things right between the two of you. Now she can barely move without your permission.”

“It is the bond, sister,” Luna said, hanging her head. “I had thought time would weaken its hold on Twilight and myself, but it has not. It keeps driving down her will anytime she’s around me, and worse, it keeps pushing me to treat her as mine.”

“What do you mean, yours?” Celestia asked, less angry now that it was obvious her sister felt guilty over what was going on.

“Must I spell it out?” Luna said, sadly, looking toward where Twilight’s arrival at the buffet was greeted with smiles and laughter. “I want her, sister. I want her, at my hooves in chains, serving me wine. I want her dressed in silks, prancing before me in offering. I want her in my bed, leashed and collared, shuddering with pleasure as I take her and mark her as my own ”

“Why didn’t you tell me it was that bad sooner?” Celestia asked. “You know I’d be more than willing to help you with this.”

“Until this evening, and Twilight’s return to Canterlot,” Luna said, “I had truly thought it was getting better, but as we have seen, it has not. With Chrysalis coming for you tomorrow there is no time to deal with this, so I will just have to do my best to resist until your return.”

“That’s why you told that Moon Dog to protect Twilight from you,” Celestia said, as she realized how much her sister cared for Twilight. “In case you slip, or break all the way. Somepony to stop you, just in case.” Luna nodded, and Celestia said, “When I return, and am back up to speed, we will find a way to break this curse. I swear it, sister.”

“Thank you,” Luna said, with feeling, then she noticed Valiente staring at them. “We should make our way to the tables now, as someponies are beginning to notice we aren’t with the others.” Together the two alicorns made their way to the others, Celestia with a wing over her sister offering silent comfort and acknowledgement of the struggle Luna was facing.

Dinner and afterward went well as the group of friends talked far into the evening. Twilight and her friends all promised Celestia that they would do their best to help Luna govern in Celestia’s absence, to be there when Celestia came back, and to bring her back by force if necessary. Finally, it came time to rest, as tomorrow promised to be eventful.

“I’m afraid we all need to be off to our beds,” Celestia said, and then turned to Twilight. “Would you like to spend the night with me, my faithful student?” Twilight looked at her former mentor in surprise.

“But, what about Luna?” Twilight asked, ears raised at Celestia's question. “Don’t you want to spend these hours with her?”

“Luna and I have already said everything we need to say to each other,” Celestia said with a smile. “She knows how much I love her and I know that she loves me from crest to cannon.” Luna smiled and blushed a bit. “Tomorrow will be serious but tonight, I would just like some quiet time curled up with a good friend, like many nights before.” It was Twilight’s turn to blush, even as she nuzzled Celestia’s side and her friends all “d’awwed.” Together teacher and former student left the dining room, with Mouse trailing at a respectful distance, and Luna turned to the others.

“I’ve arranged for rooms for all of you in the castle. As well as wake-up calls for breakfast,” Luna said, with a small smile. “The guards can show you the way and I will see you all in the morning.” The others gave her a quick hug and said their goodnight’s to her. Once the others were gone, Luna left and made her way toward the kitchens, for a late pot of tea. Occupied with her thoughts, Luna didn’t notice the alabaster ghost shadowing her until she entered the kitchens themselves.

Tea secured in her magic, Luna made her way back to her rooms and lit a single pair of candles on arrival, preferring soft, gentle light to something more garish. The dim light concealed the length of light chain padlocked around one of the legs of her bed as it curled underneath. Luna took no note of the chain as she climbed onto her bed. In fact, it wasn’t until she took the first sips of tea that she heard the faint “clink” of one link of chain hitting another.

Luna flung her tea one way, while leaping in the other direction out of her bed. She hit the floor, spun and aimed her ignited horn at her bed, “Whoever you are, come out now. Slowly.” The soft sound of links of light chain clinking against each other came from under the bed as Valiente’s muzzle and eyes peeked out from underneath.

“May I come...out all the way, Mistress?” Valiente asked. Her eyes might have been lowered submissively but the words were delivered in a sultry, sensuous tone.

“Valiente,” Luna huffed out. “You scared the wind out of me. Yes, please come...” Luna’s voice trailed off as the alabaster mare belly crawled out from under the bed, revealing that she wore a gold collar locked to her throat, with several feet of golden chain firmly and securely leashing her to the foot of Luna’s bed.

“I listened in on you and Princess Celestia,” Valiente confessed. “I heard you tell her what you want to do to Twilight, what the bond is pushing you to do. It occurred to me that if you could only release those urges, on somepony that trusts you, that maybe the bond would give you some peace at least for awhile.” Luna swallowed as she realized that Valiente knew the dark urges Luna was trying to control and even so, here she was offering herself.

“Valiente, where is the key to the locks on that chain?” Luna asked, drawing a step or two closer, in spite of herself.

“You mean this chain, Mistress?” Valiente asked rhetorically, as she wrapped a few lengths of the chain around her body and strained against the links. The golden links showed off her legs and barrel to good effect, while also demonstrating that she stood no chance of escape.

“Yes, Valiente,” Luna said, now standing over the leashed mare before her. “Where is the key?”

“I flung it out the window,” Valiente said, stepping out of the links wrapped around her and placing a length of the chain in Luna’s hoof. “I’ve been a very bad mare, and my mistress should punish me.”

Luna slowly drew the chain upward, pulling on Valiente’s collar and forcing her to stand on the tips of her hooves. A sense of power and fulfillment filled Luna, as the white mare in her clutches began to move as Luna desired. Still holding the leash tight, Luna drew her nose from the hollow of Valiente’s throat up to the point of her jaw, deeply inhaling the captive mare’s scent as she did.

“You are playing a dangerous game,” Luna growled, letting off the chain and allowing the alabaster mare to stand normally. “Does Rarity know what you are doing, or what you obviously intend?”

“She knows and approves,” Valiente said, as she pivoted in the collar to grind her flank against one of Luna’s legs. “We both know you need to release the rage from your system. To become the savage Alpha mare, even if it is just for tonight. Of all your friends, who love you very much, I am the best suited for this.”

Luna could feel her control fraying as desire warred with loving concern, “If I do this, I won’t be able to hold back. I...I could hurt you, maybe even break you. I don’t think I could stand to hurt you.”

“Mistress, I trust you not to permanently break your toy,” Valiente said, turning to nibble delicately at Luna’s chest fur. “More, Rarity trusts you. She always has trusted you.” Luna felt the heat growing in her, the fire, the burning need to take the mare before her and keep taking her until she submitted to her dominance. Luna fought the desire down, mastering it, but it was like holding a balloon filled to capacity. The slightest bump could make it explode.

“You have my permission to do as you will with me,” Valiente said, turning to face the bed and flagging her tail as she did so. “I am yours, take...eep!” Valiente squeaked as Luna lunged forward and grabbed Valiente’s crest with her teeth. Valiente went limp in the grip of the larger pony as Luna half-carried, half-dragged her onto the bed, the chain leash dragging behind them with a *skirring* sound.

Luna’s vision was fully occupied by her captive, and she opened her jaws allowing Valiente to drop onto the bed covers. She had wanted this mare for so very long. She had desired her, lusted for her and dreamed of her on many a night, when she was curled on a cushion in this very room, and a tingling fire danced along her limbs as at long last, alabaster perfection lay between her hooves.

“You,” Luna growled, standing over her prey, “are mine.”

“Yours,” Valiente agreed, pulling her leash tight, to show she was indeed captive to the dark beauty that was her mistress. Who moved her head forward kissing and biting the line of flesh directly above the collar. Valiente lifted her chin a little, giving Luna better access to her throat, moaning with pleasure as the heat coming from Luna began to ignite a fire within her own belly.

“Yesss,” Valiente hissed in pleasure. This was the fulfillment of what she had been made for. To be controlled, to be taken, to be fully under the dominance of an owner who desired and needed her. Luna flipped Valiente over onto her belly and continued the line of bites and kisses, collaring Valiente again with a line of soft welts.

The fire of need inside of Luna raged out of control, her passion and desire for Valiente sinking into her core. She drew a line down the mare’s back as she inhaled her scent, heading for what she could tell was a molten core within her pony. She pulled firmly back on the leash as she reached the hindquarters, forcing Valiente into a taut bow. Maintaining the pull, Luna dipped her nose into Valiente’s moist, fragrant nethers.

P-please,” Valiente gasped, air nearly cut off from the collar digging into her neck. “Please taste me. Taste how much I want you.” The moist treasure beckoned to Luna and she dragged her tongue along the soft, wet folds, feeling Valiente shudder and gasp as she did so.

“Yes, my little pony,” Luna said, the taste of the well-aroused mare invigorated her. This is what she wanted. To be given her due, her right. To fully possess and use a strong, powerful, beautiful mare in the manner that the strong always took what they desired, and the mare wearing her chains fit all those categories. But yet, it would not do to damage such a possession, and Luna let the leash slacken. Valiente forequarters dropped in gratitude, her chest heaving and drawing in air, as the collar stopped compressing her airway.

Luna slackened the chain all way and pushed the white mare’s head down to the covers, eliciting a small moan from her. Luna slid her hooves slowly back along Valiente’s flanks, scoring lines of fire along the soft barrel until they arrived at the hips, where they dug in and Luna used the purchase to draw Valiente’s slit toward her waiting muzzle.

Soft wetness greeted Luna as she nosed aside the outer folds and she began to lap at the growing moisture. She licked and nibbled all along the folds, and the moans of her collared captive grew louder and more frequent. Luna drove her muzzle forward, parting the inner lips and her tongue began to delve into the revealed slick passage.

“M-Mistress, have mercy on a poor mare,” Valiente begged as her body became wracked by spasms. “Finish me off, please.”

“Whose are you?” Luna demanded, as she lifted her muzzle away from the treasure it had found and she jerked the chain leash.

“Yours, Mistress,” Valiente cried out. “Yours, in all things!”

“What part of you is mine?” Luna asked, her voice becoming low and hungry.

“All of me,” Valiente said, pleading. “My body, minds and souls are yours.”

“Yes,” Luna said, and the hungry growl was back. “Which means for you, there will be no mercy.” Valiente’s despairing wail swiftly turned back to aroused moans as Luna dove back into her tasty meal, tongue delving deep as the moisture flowed from Valiente, thick and fast. Luna continued to lap and nibble and drive her tongue deep, as Valiente’s arousal filled her senses. Then Luna found the pearl of the sensual mare and she latched onto the delicate nub, tonguing and sucking at it as if it were a teat to draw milk from.

Valiente’s moans turned to wordless cries as Luna flogged the nub without mercy. After some minutes, Valiente could stand no more. “Luna!” Valiente cried out, as she came hard, soaking Luna’s muzzle with her wetness, even as her body spasmed over and over again in orgasm. The orgasm went on, rolling through Valiente for almost a full minute and at the end of it she lay gasping for air.

Luna gave her prize some moments to pull her shattered body and mind back together, and she noted that Valiente may have been right. She was able to think more clearly now, but she wasn’t even close to finished yet. To that end, she pulled Valiente’s hindquarters off of the bed, but left her barrel and forequarters supported.

“W-what are you doing to me, Mistress?” Valiente asked, her breathing returning to normal.

“Why preparing you for my pleasure, as you offered,” Luna said, a wicked smile playing on her lips, while a whimper escaped Valiente’s as she realized that her mistress was far from done with her. “Now that you are fully warmed up we can proceed to the main event.” Valiente didn’t try to fight or struggle, she merely bowed her head and to Luna’s surprise, smiled slightly.

“Something amuses you, my pony?” Luna asked, as she cast an old, old spell, and felt its familiar tingle in her loins.

“Just that I am finally going to get something I’ve wanted since the day I came to be,” Valiente said. “Do not be gentle with me, Mistress. Take me with all the fury and power of an alicorn because I need it as much as you need to give it.”

“As you wish,” Luna said, as she reared up, coming down with her forehooves on either side of Valiente’s shoulders, her belly scraping along the submissive mare’s spine, and Valiente felt something begin to poke and prod at her folds.

“Mistress, what do you ha...oh, my,” Valiente said, as she glanced behind her and saw that Luna, her mistress, was now sporting a very impressive stallionhood. A very, very impressive stallionhood that Luna was beginning to slowly push into her.

“Yes, my pony,” Luna said, “I do have one, and I’m going to fill you with it.” The cock was magically lubricated and combined with the juices still dripping from Valiente it encountered almost no resistance to its entry. Even so, Luna paused halfway in to allow her mare a chance to get used to the fullness.

“Oh, stars above,” Valiente moaned. “So good, Mistress. Fill me, breed me.” The words gave Luna an idea and a pair of cords snaked out to snare Valiente’s rear legs to the bedposts and hold them open. At the same time the leash locked to her collar was pulled forward and wrapped around the bed frame to secure it there.

“Since you wish to be bred, bred you shall be,” Luna said, as she slowly began to thrust in and out of her bound captive. To say that Valiente wanted this would be like saying water was wet. She had originally been created from the sexual, sensual, submissive side of Rarity and although the two of them had been through many adventures, those things remained at her core. To be inescapably bound, and taken by a strong, dominant master or mistress was something she desired above all else.

Luna set a steady pace at first, rocking back and forth in a steady rhythm. Slowly, Valiente began to push back against the thrusts, and Luna took this as her cue to drive deeper and deeper with her magical member. The thrusts became deeper and faster, Valiente’s moans and cries of pleasure urging Luna on. At last, Luna hilted fully in the mare beneath her and paused. Valiente, caught off guard by Luna stopping, tried to rock back and forth to give herself the last few iotas of friction she needed to reach her peak. Almost weeping with frustration she burst out, “Just buck me already!”

“So, the servant presumes to command the Mistress,” Luna purred in Valiente’s ear. “Perhaps I should just stop entirely and lock a chastity belt on you.”

“Please no, Mistress,” Valiente begged, almost instantly. “I’m sorry, I’ll be good.”

“You do feel good around me, writhing and shuddering,” Luna said, into Valiente’s ear, even as the submissive mare quivered beneath her. “But as you said, you’ve been very naughty and it is time to punish you. Are you ready to accept your punishment?”

“Yes Mistress,” Valiente said, almost weeping with the need to cum. “Whatever you do, I am yours.”

“Indeed,” Luna said, pulling most of the way out and her horn flared again with magic. “Prepare yourself to be used fully.” Valiente’s only reply was a whimper that changed to a gasp, as she felt something begin to ease its way into her rosebud.

“B-but you are already inside of me...how?” Valiente said, as she tried to look behind her. The collar and leash pulling her head forward prevented her sight of Luna’s second cock, as it breached her anal defences. With excruciating slowness Luna pushed forward until she once again and driven herself in up to the hilt. Or in this case, hilts. Valiente’s mind began to shut down as the incredible fullness of being double penetrated fired every pleasure center the double mare had.

Safe and secured in her mind cage, Rarity briefly considered trying to break free to take control but quickly decided to ride out the storm of pleasure that was tearing through their shared mindscape in the safety of her cage. A storm that rose to an ever higher pitch as Luna began to piston back and forth, rubbing the sensitive wall of flesh that separated the cocks within Valiente’s body, and even Rarity herself was starting to regret not doing this sooner, with their owner and mistress.

Luna could hear the moans and gasps from her mare, as she worked her twin cocks in and out of her captive concubine. Rarely in her long life had Luna felt so alive, with such power, so wanton and wonderful. It was all she had ever wanted and the simple power of possession filled her even as she continued to pound Valiente. Valiente was gone completely to the rut, mindlessly pushing her hips back at Luna in time with each thrust, wordless noises of ecstasy coming from her mouth. Luna could feel Valiente’s internal muscles spasming against the cocks filling both her passages, trying to milk them and Luna tried to resist her own orgasm.

Instinct and dark desire had other plans though and instead of slowing down, Luna gave into those desires and sped up, pounding Valiente’s plot even harder, even faster, and a tingling heaviness began to grow in her. Like the stallions of old she would take this mare who had offered herself to Luna, take her, possess her and breed her as a broodmare for her herd. Need rising to a fever pitch, she grabbed onto Valiente’s shoulders and began to buck the mare under her for all she was worth.

There was no longer any room for thought in either mare, both now were running on pure instinct and the pounding rhythm of flesh on flesh filled the room. For long minutes that rhythm and the sound of gasping breaths were the only sounds. With a final, exultant cry Luna drove forward one last time and hilted deep inside her mare. As she did so both of her cocks exploded together inside of Valiente, filling her with creamy, magical cum. As the tingling magic hit Valiente’s inner walls it triggered her and she came as well, her walls clamping down on the cocks in both her passages and drawing out every drop they could.

The rippling, tugging muscles working on her cocks caused Luna to explode again in a second orgasm and Valiente was filled to overflowing. The captive mare was just starting to come down from her most recent orgasm when the fullness filling every inch of her threw her into another. Completely spent, Luna collapsed to the bed, pulling Valiente down and into her belly. She had just enough presence of mind to loosen the leash and break the ropes holding Valiente’s rear hooves in place. Still intimately connected the two lay on the bed, sweat cooling in the fur of both, and Valiente continued to shudder with aftershocks, pleasantly vibrating around Luna’s slowly collapsing cocks.

“Thank you, Valiente,” Luna whispered into her mare's ear. “That was simply glorious.” Valiente heard the words and she slowly moved back into control as she felt Rarity’s pride and approval at how they had helped their princess and mistress.

“Has Valiente been punished enough, Mistress?” Valiente asked softly.

“Valiente has been wonderful,” Luna said, and Valiente could hear the pleased tiredness in her mistress’ voice. “But it is time to rest, so the last of your punishment is to remain here with me tonight.”

“I couldn’t leave even if I wanted to,” Valiente said with a small giggle, as she snuggled deeper into Luna’s belly fur. “You worked me over quite well, Mistress. I’m likely going to have some difficulty moving come the morning, and I’m still chained to your bed, after all.”

“So you are. Rest now, and know you have my gratitude,” Luna said, extinguishing the candles and closing her eyes.

“One last thing, if I may Mistress?” Valiente asked, even as the soft warmth around her began to drag her toward sleep.

“Mhmm”

“Mistress...exactly how fertile are you?”

Author's Note

And so, we see how all three of our favorite mares have issues pressing in on them. Chrysalis approaches, Moon Dogs are moving into place, and interesting magics are in play.

This is going to be the last update to this story for awhile. Due to life zapping me with mega-bills I have had to engage in some heavy duty commission work and those that pay the bills, get the priority. Once I'm clear of that, all my non-commissioned work will see a bump.

This chapter is brought to you through the assistance of my current patrons:

Thank you, very much. It really is a big help.
