Let Sleeper Dogs Lie

Let Sleeper Dogs Lie

by neorenamon

Rarity lay panting on her own bed.  Even though she managed to break free but a moment earlier, she was all but helpless under the magically enhanced orgasm.  She was sure her bosom was now at least as large as Celestia's, and she didn't even want to think about her butt right then.  Her sheets were in dire need of changing until she remembered that her Nightmare counterpart stole her horn and stuck it in her own nightstand.  The cruelest irony was even though she could get the horn back at any time, she couldn't restore it without already having her horn restored.

There was one other option, but she wasn't truly desperate enough to resort to the blackest magic she had access to.  Well, at least until her Nightmare counterpart recovered her chest and found that magic trinket herself.  With her enormous and hard nipples, she knew no one would ever mistake her for her old self.  In fact, without her horn, she was sure most would mistake her for an evil Earth pony instead of a unicorn.  A small favor indeed.

She sat up and gingerly touched her throbbing nipples.  They so longed to be caressed that she could hardly stand not to.  She could hardly think straight until she gave them some attention, but knew in the back of her mind that if she went too far, there would surely be another massive orgasm and yet another breast expansion.  It would well leave her with the biggest breasts that the world had ever seen... on a pony.

But the need was for her to fondle herself was so great, it took every shred of remaining willpower for her to make herself stop.  At least she could now think about her next action with a... minimum of distractions.  While she wanted to take the horn and run after Nightmare Rarity, she knew the sight of her would cause a panic wherever she tried to go.  With Royal Guards in town on behalf of Princess Twilight, she was sure she would be quickly on her way to a Canterlot cell.

On the other hand, Celestia or Luna could use their magic to restore her horn.  But she would have to find a way to at least bypass if not outright defeat one of their Nightmare counterparts... and without her horn!  It seemed that most of her solutions to fix her removed horn only worked well... with her horn!

She shook her head hard, and tried to think of other things.  There was magical things she owned that were not kept in that chest.  Things that her Nightmare counterpart wouldn't think of as dangerous to her.  She looked at her closet, and remembered the secret closet she kept behind it.  That was where she was going to find some assistance to save Celestia and/or Luna.

All but falling out of bed, she managed to stand as she wondered just how long it took Celestia to get used to having so much of her center of gravity ahead of her like that.  She would have to ask her about that sometime.  One shaky step at a time, she made her way to the outer closet door.  She threw the door open and made her way past her regular clothes as she searched for the hidden level in the back.

It took several minutes of searching and ignoring the sensations she felt every time a nipple brushed against one of her silky garments, but there was the satisfying click as the secret door popped back and slid out of her way.  Then she saw them.  Her most special genuine black leather Dominatrix gear.

The first thing she put of was the wide girdle.  While it made her waist thinner, it also made her boobs and ass look just a little bigger.  But it also enhanced her strength and stamina, and that was more important at the moment.  In fact, the tighter she secured it, the better she felt.

After that came a pair of fingerless black silk gloves.  It served the dual purpose of both increasing her spanking power, and making sure her palms were padded enough not to injure them in the process.  In fact, she wouldn't have been surprised if she could use her hands to punch through a cinder block wall.

Next came a black leather choker with silver studs that she strapped about her neck.  It altered her voice, making it sound both louder and more commanding.  There was a few other minor effects that she had never dared to try before as she never had a need to.

Lastly, she took out a pair of punishing tools:  A black riding crop and a black cat-o-nine-tails.  Each was made to inflict the maximum amount of pain with the minimum amount of physical harm.  She was as ready as she was ever going to be to rescue Celestia or Luna from their Nightmare counterpart.

As she stomped towards her door, she also realized she was really in the mood to inflict some pain on somepony...

...

Luna struggled and squirmed in vain to get away, but her counterpart was giving her no peace.  She was getting fisted in her pussy, and already had two orgasms from that rough treatment.  Her eyes were tightly closed because she couldn't stand to look at her own fangy and smug grin any more.

'You know I can force you to see me in your mind's eye, right?' she asked in her head, 'But we suppose that's besides the point.  We should do you a great big favor by returning you to your Nightmare Moon state.  With our combined power, we could overthrow both Celestias and rule an Eternal Night over ALL of Equestria.  Your secret wish would come true.  All we have to do is make sure those blasted Elements of Harmony cannot be used against us.  I suppose Discord might prove to be troublesome... if we couldn't just wrap him about our little pinkies with our huge... dark charms.'

'**NO!  We must NEVER become *HER** again!*'

'Your mind may say NO, but your body is saying YES!  Deep down, we both know that the feeling of being Nightmare Moon was the BIGGEST TURN ON YOU'VE EVER FELT!'

The whites of her eyes turned black as strange green 'flames' began to leak from them.  Luna could see them even with her eyes closed.  Nightmare Luna made sure of that.

'I'll just... help you along in the right direction.'

She could feel the black magic flooding her mind, dampening her will to resist even as she rallied all of her will that she had left inside of her.

'Just relax and go with it, my precious.  It will all be over before you know it.'

'NEVER!!'

'Be that way then.  Perhaps the pain will make you even hornier than you are now.'

At least the fist was pulled out of her vagina.  She could here the sucking sound as even more of her juices were splattered about the couch and her inner thighs.  But something was not feeling right with her body and her mind.

'BLAST!!' thought Nightmare Luna angrily, 'Somepony else has already asserted their control over you, and it's too powerful and complex for me to undo right now!'  She laughed evilly as she continued, '**It looks like you already serve another Master!'

'YOU LIE!!'

'It seems you serve and don't even realize it!  How delightful!  I can hardly wait to twist that control over to US!'

'Monster!!'

'Oh deny it all you like!' she hissed, 'I couldn't make this up even if I wanted to!'  Her evil laugh was loud enough to make her ears hurt.  'But to take control of you, I may well have to confront the one who put it there in the first place.  I have this feeling that whoever they might be, they are a distance away, and living some place under the ground.  It does seems appropriate that they should be hiding in a hole.'

Luna's mind recoiled in horror as she realized SHE was the dog's sleeper agent the whole time!  That SHE was somehow twisting the nobles to act against Equestria!  It was almost too shameful to even contemplate!

'Let me turn you back into Nightmare Moon!' she hissed, 'As her, you need never feel guilt or shame ever again!  I can make all those horrible feelings you are experiencing right now go away forever!'

...

Nightmare Celestia was surely enjoying herself.  After slapping and tightening the largest clamps she could find on Celestia's sensitive nipples, she placed similar clamps all the way down her netherlips, closing her pussy in the process.  Then she took obscene pleasure in taking a crop and striking her upside down flanks until they were bright red and searing hot in pain.

'I will so enjoy breaking you before I take over Equestria!' she hissed, 'You shall soon submit to me even more than you submit to Rarity!  VERY SOON!'

'NEVER!!' she replied.

'Delude yourself if you must, but you know deep down that I alone am your perfect Master.  Miss Rarity is a pathetic wannabe compared to me.'

'If you can think that, then you don't know how Rarity feels about me at all!'

'What?!  Do you seriously think that stuck-up tramp actually *loves you?!***'

'She only dominates me because that's what I *want** her to do!*'

'Truly sad...' sighed Nightmare Celestia, 'I shall surely never be as weak as you!'

'Do you really think you could come from me, and NOT get my faults?!'

'YES!!'

'Then you are truly the deluded one!' thought Celestia smugly.  That merely got her 'rewarded' with more stinging strikes against her painful flanks.

"LEAVE MY BITCH ALONE!" howled a voice in Nightmare Celestia's ear as something struck her hard across her jaw.  The force of the blow sent her spinning away from Celestia.

'Great!' she thought, 'Another minor nightmare to bother me!'

"I am no minor nightmare!" she hissed, "I AM YOUR WORST NIGHTMARE!"

'You've come to save me, Mistress!' thought Celestia.

She looked at Celestia before glaring at Nightmare Celestia, and howled, "HOW DARE YOU TREAT MY SUBMISSIVE SO SHAMEFULLY!!  YOU WILL PAY FOR THIS!!"

'WAIT!  Are you the *real Rarity?!**' thought N C, 'I must say I love the new look!  Nightmare Rarity has surely outdone herself this time!*'

But Rarity simply looked at Celestia and said, "Give your Mistress a moment, and I will set you free.  NO PONY gets to dominate you but ME.  I promise you this... my love."

'I cannot wait,' thought Celestia.

"Actually, I don't think you have a choice about that."

'Oh, I think I'm gonna puke!' thought N C.
