Let Sleeper Dogs Lie

Let Sleeper Dogs Lie

by neorenamon

Luna was only half paying attention as Nightmare Luna glared over her.  If she couldn't remember what she did as a sleeper agent, then she had no idea how to find all of the ponies she had influenced in Canterlot.  Even knowing that, she didn't know when she would be activated again, who pulled her strings, or what triggered the switch inside her head.  It seems her Nightmare counterpart was at least right about one thing: She was going to have to go back to the Diamond Dog's mine-fortress and make the Shaman release her from his insidious control.  Perhaps then she could remember all the ponies she had turned, and could act to fix them all.

'ARE YOU IGNORING US?!' thought N L hotly.

She had almost forgotten that she was laying on top of her bound and defenseless body even as she was shoving her whole hand up into Luna's vagina.  Their breasts were mashed against each other tightly.

'We are trying our best to,' she thought back.

'Now you are just upsetting us,' came the retort, 'and you don't want to see us upset!'

'It begs the question,' thought Luna, 'What more can you do to us?'

'We are so glad you asked!  It seemed like we were going to have to force a solution on you without you being prepared first!'

'In order to apply a solution, there must first be a problem.'

'And that problem... *IS YOU!!**' she hissed, 'While we cannot seem to completely control you as we wished, we CAN make you more agreeable to us!*'

Luna saw her horn and her eyes glowing with dark green energy as her rope muzzle was undone, but her mouth was forced wide open before she could utter a thing.  Then N L forced a full throated kiss on her, sealing their mouths together tightly.  She felt a twinge of panic as something magical was being forced down her throat.  Tingling sensations ran down her throat to her stomach, and then spread outwards towards the extremes of her body.

She squirmed and struggled as her vision became fuzzy.  Then it went completely black.  She seemed to be floating in a vast black void, but soon she could see the twinkling of stars emerging from the dark.  Then something seemed to rise into her view from someplace beneath her.  It was the moon - a blood red moon.  Across it's face was an image of a mare's head and neck that she hoped she would never have to see again:  Nightmare Moon.

'Did you miss us?' she asked.

'Like Hoof Rot,' she replied.

'Oh, that sarcastic sense of humor,' she snorted, 'That is one thing that we surely did not miss.'

'The Elements of Harmony destroyed you!'

She laughed as she said, 'Do you think that pure evil can actually be destroyed?!'

'We hoped so.'

'Even you know by now that I wasn't fully purged from you system,' she replied, 'and did you ever stop for one moment to ask yourself what happened to the dark crystal fragments that were left behind after you were... saved?'

'Big sister assured us that they were all destroyed!'

She laughed even louder.  'FOAL!  She lied to you!  How can you dispose of something that wasn't even there?!  The shards returned to the darkness as soon as you were out of the room!  Celestia told you that nonsense just to make you feel better about yourself and what you had wrought!'

'NO!!'

'YES!!It was only a matter of time before somepony figured out how to rejoin the darkness inside you with the power that was left behind that day!'

'WE WILL NOT COME BACK TO YOU!!'

'YOU HAVE NO CHOICE!'

A sharp pain across her muzzle suddenly brought her back, staring into the eyes of Nightmare Luna.

'Do you dare ignore us again?!' she asked madly.

'No, I was having a pleasant chat in my own mind with Nightmare Moon.'

'EXCELLENT!' she replied, 'Then she is coming back!  Even now, the physical part of her return is well underway!'

Luna realized that unless the world was shrinking, she had grown a bit in every way.  The way she was taller back when she was Nightmare Moon.

'BIG SISTER AND THE OTHERS SHALL SURELY PURIFY US ONCE MORE!'

'Once the Elements of Harmony have been dealt with, you will be once of us... *FOREVER!***'

Luna's vision changed slowly as her mind was filled with thoughts she had long hoped she was over.  She remembered the rage and jealousy about how big sister was always loved and respected more than her.  How her nights were never truly loved and revered as much as Celestia's precious days.  She remembered how Celestia merely pretended to love her even while she kept the full weight of her oppressive hoof on her throat.

She cried as she thought desperately in the back of her mind, 'No... not her again... We were wrong to think things like that about my big sister... wrong to think such things about Equestria and the ponies within... *I WAS WRONG!***'

But all she could hear was Nightmare Luna gloating, 'Welcome back, Nightmare Moon!'

...

Meanwhile, the altered Rarity was fighting to save Celestia from Nightmare Celestia.  She was all but in her face as she hit her over and over again with both the crop and the cat-o-nine-tails.  But the harder she hit, the more N C just laughed in her face.

'Do you really think that mere pain will stop the likes of us?!' she thought, 'Without you horn and your magic, you are truly a pathetic thing to behold!'

But Rarity simply turned the hand holding the crop sideways and buried her fist into Nightmare Celestia's stomach.  She gasp and nearly doubled over as she was pushed back.

"I knew you would not be affected by pain much," she replied, "It was merely a ruse to keep you close enough until I could do that to you!  Not so smug now, are you hag?!"

'We will make you suffer for that!'

"Promises promises!" she hissed back.

N C pointed her finger at Rarity as a blood red jet of flame shot from it at her.  But the flames moved so slowly, and her aim was so high, that she easily ducked underneath.

"Your aim stinks!" she snapped.

'Oh no,' she replied, 'I'm going to hit *EXACTLY** what I was aiming at!*'

Rarity turned just in time to see the bolt of flame going right at Celestia's bare crotch (as she was still hanging upside down by her hooves).  Moving with speed she had never felt before, she ducked under the bolt, and stood up with her back to it as she embraced Celestia's hips.  A blood curdling scream came from her lips as her whole back burned.  It even felt like most of her mane was burned away as well.

'Exactly what I thought you'd do, you simpering weakling!'

"I'm so sorry," she sobbed, "Your Mistress has failed you..."

'NO!' thought Celestia, 'Don't die for me!  I cannot bear the guilt of another death on my hands!'

'Don't you worry about a thing,' hissed N C, 'I promise I'll take good care of her once you're dead and gone!'

"I promise I'll see you in Tartarus first, bitch!" she snarled as her eyes glowed sickly green.

'What trick is this?!' she asked, 'You have no horn!  How can you have any magic?!'

The crop and the cat-o-nine-tails merged and were reforged into a golden glaive.

'You aren't even a complete pony!!" she hissed, "If it weren't for Celestia's defenselessness and your vile willingness to hurt her to get at me, I wouldn't have had to resort to THIS!!"

With a single stroke, she cut N C in half from her head to her crotch.

'You haven't seen the last of us!' she hissed as she burst into flame, and then faded as a cloud of black smoke.

The glaive clattered to the floor as she raced to embrace Celestia's hips again.

"Are you alright?!" she asked.  But then she realized with Nightmare Celestia gone, she couldn't hear Celestia's thoughts any more.  Just the panicked mumbles against her bound muzzle.  She leaned down to retrieve the glaive with one hand as she kept her grip on Celestia with the other.  Then she supported her full weight as she used the glaive to slash the chains above her hooves.

Gently lowering her to the floor, she used the tip of the glaive to cut away the ropes binding her.  She was kneeling by her submissive's side as she did so.

"Mistress?!" she asked as she sat up, "Where is your horn?!"

"Nightmare Rarity removed it with her powers," she replied, "I left it in my room for safe...  MMMPPPHHH!"

Celestia was so relieved to embrace her Mistress again that she went right to a deep kiss.  She was holding Rarity in a death grip even as she tried to protest.  Their massive breasts were mashed against each other in the process.  Rarity found that she was becoming aroused again, and that surely wasn't good.  Yet she just couldn't break the kiss, or get Celestia's tongue out of her mouth... or perhaps she just didn't want that tongue to go away.  With one arm about her back holding her up, Celestia leaned into Rarity even as her hand reached down to Rarity's mareslit.  By the time she even thought to close her knees, Celestia's fingers had already began probing her hot wet vagina.

Rarity was scared about what would happen if she should climax again, and yet her body was aching to feel it again no matter what the consequences may turn out to be.
