A visit from a Nightmare

-Canterlot Castle-

Celestia was sleeping peacefully, dreaming one of her favorite dreams. In it she had once again defeated Nightmare Moon and gained her loving sister back. Yes, she knew it was actually of a memory than a dream, but none the less she enjoyed every time she had this moment. It was, in a roundabout away, like a personal redemption song for her. However something soon struck her as odd, instead of the Element Bearers coming over to them, they seemed frozen in place, and she instantly knew that cause of it.

"Come to relive the moment that once again reunited us dear sister?" Celestia said with a warm smile, but something seemed off as the temperature around her suddenly dropped and the landscape shifted to Luna's realm, the dreamscape.

"Actually no Tia," The Princess of the Night said as she trotted up to Celestia, a dream orb being held in her magic. "I have come to ask thee a few questions regarding one Bon Bon..."

The moment Luna said the name Celestia's coat somehow managed to turn a few shades whiter as she gulped. Neither Twilight, or herself, had taken into consideration their new pet would be traumatized by what the prospect of what will happen to her. She and Twilight just wanted to have some "fun" with her, nothing that would put the Earth Pony's health in danger. For the slightest of moments, a mere blink in the eyes of the universe, Celestia felt bad for forcing Bon Bon into this situation. That feeling was quickly replaced by fear and trying to save her tail.

"Now Luna," Celestia said calmly. "seeing as you are over dreams, you probably see plenty of fantasies involving me, you, Twilight, and Cadance. After all, who wouldn't want to do it with a princess?"

Luna blushed and had to look away, slightly coughing to regain her composure before relooking Celestia in the eyes. "As true as that may be, I take special priority when it comes to nightmares, and this dear sister was a nightmare..."

Luna then hoofed the dream bubble, which was none other than Bon Bon's, over to Celestia. What the Solar Diarch saw not only horrified her, but for some strange reason amused her. Granted, most of the things in the captured nightmare she and Twilight would never even attempt, but other things gave her new ideas to try. A few, however, made even her frosting-clad stomach want to curl.

"Why I would never-..." Celestia said with a stammer but she was cut off by a voice appearing behind her.

"Oh you would Mol Celly Ti'la Sol..." The voice from behind the alabaster alicorn said, making both Diarchs spin around to see who said it. When they looked their jaws dropped, there before them was a pony who Celestia thought she had banished away for good...her own personal demon, Daybreaker.

"That is a lie Daybreaker and you know it!" Celestia said a little irritated. "You are nothing but evil personified into a admitting-hot form of me. Just as I banished Nightmare Moon I sur-"

"You never beat me Daydream..." Nightmare Moon said appearing, for some unexplainable reason, out of Daybreaker's tail. "Both times it was the Elements of Harmony that vanquished me...you did nothing!"

"That maybe true, but she cared enough to free me from you Nightmare," Luna said with a snarl. "and I forgave her a long time ago..."

Nightmare Moon chuckled. "Such flattery will get you two nowhere, for me and my sister will soon be the ones in control. You both have many "pet peeves" towards each other, keep in mind I am speaking from experience here. The best way to settle them, of course, is to "get rough in the sack" as it were. That is what me and Daybreaker did and it has made a huge difference, after all..."

"Princest is wincest." Daybreaker said nuzzling her own younger sister, who gave a small purr.

Celestia just stared and Luna's jaw dropped so much she could swallow a whole pineapple. "So you are suggesting me and Tia..."

Nightmare Moon nodded. "Indeed we are Luna...although I prefer pet names. Like for example, mine is Novi and Daybreaker here is Corona. You two can keep it simple with "Tia" and "Lulu" since you seem to call each other that a lot. Me and Corona both know you each have fantasized it, after all, we are you..."

"Of course they have darlings..." Another voice, one that made the four alicorns stare in puzzlement, suddenly said from above them. Their heads snapped up so fast it was a wonder they each didn't get whiplash, and there was Rarity, although she looked slightly different. She was taller, nearly as tall as Luna, with a horn that was similar to Nightmare Moon's. Her coat was midnight black, her mane and tail longer and more stylish with a white stripe complimenting the light purple. Her cutie mark had changed as well, with white stars surrounding the three diamonds.

"How the buck..." Celestia said rubbing her forehead, clearly confused and dealing with a headache.

"Quite simple," Nightmare Rarity said as she descended down to them. "everypony has an angel of darkness in them, I just so happen to be Rarity's. Va'lor is my name and domming is my game," She then looked at the Nightmare Sisters, a small smirk on her muzzle making the others shiver. "and you two will make lovely additions as my pets. As for your normal selves, they will have to be...broken first..."

Before Celestia and Luna could react, a bridle and bit had been clamped onto them. They both struggled, desperate to break free, but the reins attached to the bridle morphed and merged together into a thick leather strap that ran down their backs and wrapped around their docks. The tension then increased, flagging their tails up revealing their nether regions for all to see. The strap split and wrapped around their barrels, pinning their wings in place against their sides. The last piece, an elaborate diamond studded inhibitor ring, then appeared on their horns. The whole sequence happened in less than two seconds and left them defenseless and fully at the mercy of the Nightmare unicorn. Due to not being able to channel her magic any longer, Luna lost control of Bon Bon's dream bubble. It clattered to the floor of the dreamscape, then brightly glowed before pulling all five of them into it.

The alicorns, each sporting Va'lor's horn and wing inhibitors, observed their surroundings and saw an elaborate set up tailor made for lovely bondage activities. The ropes then glowed a deep violet and turned into vines, ensnaring the group as Va'lor crackled in laughter.

"Now then dearies," Va'lor said deeply kissing Corona, breaking the kiss only to speak. "This is a lovely environment for you to pledge your alligiance to me. I do have to thank you Lulu for such a lovely gift, how did you create this wonderful playland for me?"

Luna stammered in embarrassment, and Celestia turned her gaze downward before speaking. The bit in her muzzle hampered her speech, and made it slightly uncomfortable, but her words were clear enough to be understood. "This is all my fault...you see, Twilight and myself are in a relationship. Both of us had been keeping it secret to save the trouble of dealing with the pesky press or the stuck up nobles. Bon Bon "dropped in" on us having a clop session and, in a panic, knocked her out. We then took her to the bedroom and after she came to, we eventually had her agree to being our pet. I had no idea the poor mare would be so traumatized to the point she would have a nightmare..."

Luna sighed, she felt the same discomfort as her sister when she spoke as well. "It is also my fault dear sister, I bribed her to spy on you. I am sorry for betraying you in such a low manner, but I was starting to get concerned. You had become so distant lately and I was paranoid of having a repeat of 1,000 years ago. I hope you can forgive me."

"Lulu, yes I am hurt by your betrayal, but in hindsight I really cant blame you for feeling that way." Celestia looked into the eyes of her sister and saw a storm brewing of raw emotion. "We will discuss this in better detail later, but right now we have bigger problems on our hooves."

"Bigger indeed Tia," Va'lor giggled as a flash appeared between her legs, a 10' cock appearing when the glow subsided. "now each of you will submit to your new mistress."

Corona gulped through her bit. "You're a madmare!"

Va'lor caressed Corona's cheek with a hoof before nibbling down the Solar Demon's neck, electing a small moan from her prisoner as a response. "You say that now Corona," She then moved behind her target, pushing up using her forehooves to give her enough leverage so her tip pressed against Corona's flower. "but that won't be your viewpoint for long. By the time I am finished with you, you will have more than one mass ejection and will be begging for more."

Time seemed to stand still as Va'lor slowly pushed her length into the bound mare. Corona could no longer say her protests due to succumbing to the pleasure she was feeling. As Luna watched the scene unfold, she started to look for any means to escape, and soon found her answer, not to far from them was a whipping post. "I am sorry sister...but I have to get us out of here... Va'lor!" Luna yelled at the mare, making the thrusts stop as Va'lor looked back with a mixture of confusion and aggravation. "I will willingly submit myself to you, but in return you set the others free. All this is my fault and I need to be punished like a bad pet. Mistress Va'lor, please tie me up to that whipping post and punish me as you wish, just please let my sister and the other two go..."

Silence fell upon the group, Va'lor pulling out of Corona and prancing across the vines to get muzzle to muzzle to Luna. "You are in no position to plead and beg..." She said pulling the bit out and giving Luna full speaking ability. "You surely must offer more than that for me to agree."

Luna knew she only had one chance, she had to use the ace up her hoof. "If you do this Mistress Va'lor, I will free you from the dream realm."

"Then what is the point in freeing them if I will eventually recapture them?"

"Don't shepherds look for their lost sheep?" Luna retorted back. "Think of it as a game."

Va'lor paused to give it some thought. "Alright, but on one condition, the inhibitors stay in place and only I can remove them."

"We have a deal Mistress." Luna said holding up her hoof.

Va'lor bumped it with her own hoof then had the vines drop Corona, Novi, and Celestia. Corona and Novi tried pulling Tia away but she would not budge. "What are you doing Lulu? I have lost you once because of my own foolishness, I will be damned to Tartarus if I lose you because of your own!"

"In that case..." Luna looked at Tia with a small smile as she was lead then hooked up to the whipping post. "I guess you are damned to Tartarus then, Novi and Corona will get you out of here. Until next time dear sister..."

"Lulu no!!!" Celestia tried to make a move to get to Luna, but Novi and Corona held her back as Va'lor landed the first strike on the navy mare's back. If the whip cracking was thunder, then the strike was lightning. The strike made Luna shudder in pain, blood starting to stain her coat as the strikes came harder and in shorter increments. Luna's shrieks were too much for Celestia and she finally caved as her will shattered. No longer resisting, the tattered Princess of the Sun allowed herself to be carried away by the Nightmare sisters, a feeling in each of their guts knowing that it was either fight and submit...

...or work together and survive
