Let Sleeper Dogs Lie

"Welcome back, *Nightmare Moon*," hissed Nightmare Luna into her ear.

Luna smiled in spite of the gag.

'The Eternal Night beckons us!' she thought back, 'Let us make it come true!'

'Such pleasant thoughts,' she replied, 'but first, let us take care of your big sister.  She shall surely attempt to punish you once more for simply fulfilling your destiny.  We can no longer allow her to stand in OUR way.'

'YES!  Her interference can no longer be tolerated!'

'As soon as she had been dealt with, then we can surely make our dreams realized!' thought Nightmare Luna as her horn glowed, and Nightmare Moon's body floated off the sofa.

'We can surely walk on our own!'

'And deny you all of that pleasure?' she thought back, 'We are sure that keeping you like that a while longer will surely make you appreciate it all the more when we... deal with Princess Celestia.'

'So you do not trust us yet.'

N L paused before she replied, 'We suppose that is the best way to put it.  What you do to you big sister will tell us just how much that we may trust you.'

'Then we shall surely show you that we can be trusted to take care of our meddling big sister!'

'And we look forward to when you fully embrace and join the sisterhood of the Nightmares.'

'Do you think that Nightmare Celestia will allow us to have our Eternal Night?'

'We think she shall be quite satisfied as we shall allow her a number of Solar Eclipses each year,' she replied, 'and if she feels that is not enough... we can deal with her just fine.  We are sure that Nightmare Rarity will take our side over hers.  With three of us against her, *we shall surely get our own way*.'

'That would bring us great joy!' replied Nightmare Moon.

'We simply need to take care of the Elements of Harmony,' she replied, 'and then NONE can stand against US!'

Just then, the room lit up as a small bonfire appeared, and when that faded, they saw Nightmare Celestia scowling at them.

'Oh, did little Celestia give you troubles?' asked N L.

'Certainly not!' she replied as her scowl deepened, 'That... that... blasted Rarity did!'

'I though that Nightmare Rarity dealt with her already.'

'OBVIOUSLY NOT!' she snarled, 'Even without her horn, she was able to summon a weapon that surely would have killed me by cutting my entire body in half in not for my Nightmare powers!'

'Power without her horn,' mused N L, 'How interesting.  We must surely discover how she does this.'

'She *MUST** have a black magic relic hidden around here somewhere,' she replied, 'and I'm sure that Nightmare Rarity is already searching around for it.*'

'Are you worried that she won't share this power with the rest of you?' asked Nightmare Moon.

'Since that is exactly what I would most likely do until a Nightmare Hierarchy has been established amongst us.'

'It's the most sensible thing to do,' agreed N C.

'Then it is agreed that we should not attack Rarity unless we must,' she thought, 'and even then attack her as a group.  That is the best way to make sure she cannot prevail.'

'What if Rarity runs to Canterlot for help?' asked Nightmare Moon.

'Oh, the way she looks now,' gloated N C, 'even showing her face in public would most likely get her shipped off to a Canterlot dungeon cell before anypony would bother to take her word for ANYTHING.'

'In that case,' replied N L, 'I'm sure that Nightmare Rarity made SURE that she cannot alter her looks to get her back to anything resembling... normalcy.'

'Considering how judgemental these ponies can be, I dare say NOPONY WILL!'

...

Rarity moaned and moaned into Celestia's mouth as she was laid back almost against the floor, but she had a mouthful of Celestia tongue on one hand, and a pussy full of Celestia's hand on the other.  Even though she feared what would happen to her if she should climax again, the spell placed on her by Nightmare Rarity made her all too horny to care about it.  The juices that oozed about Celestia's fingers was a sure sign of both how aroused she was, and how much of a puddle was forming underneath her.  Yet in the tender embrace from her number one sub, both of their great pairs of boobs were mashed against each other tightly.

It was only a matter of minutes before she climaxed hard again, and she couldn't wait to feel the magically magnified orgasm as it ripped through her body.  The last one she felt was almost enough to make her pass out from bliss, and she wasn't sure at all if she could stay conscious through this one.

But Celestia was so desperate to please her Mistress that Rarity had to wonder just how often she was even breathing let alone paying attention to anything going on around them.  It took all of her focus just to keep even a loose one-handed grip on the golden glaive in case the Nightmares should choose to attack them.

Then the new most powerful orgasm she had ever felt in her life hit her like a mega-tsunami from a distant land.  Her consciousness fluttered as every nerve and brain cell seemed overwhelmed with erotic energy, and she could feel another expansion of her breasts even mashed against Celestia's as they were.  She just knew that they were now basically the largest breasts on a mare ANYWHERE in Equestria.  Her booty felt just a bit larger as well.  She couldn't help but wonder if it was the curse on her, or just plain coincidence, that Celestia was cumming with her at the same time.

But the night-skinned Rarity could only lay her head back and take long gasping breaths as Celestia finally withdrew her tongue from Rarity's mouth and ended the kiss.

"Oh Mistress," panted Celestia, "I could swear I felt that orgasm radiating from your body into my own."

"And our breasts just got larger," replied Rarity, "A curse placed on me courtesy of Nightmare Rarity.  Unless you want your Mistress to never walk upright again, I suggest you refrain from pleasuring me for the foreseeable future."

Celestia sighed heavily as she nibbled at Rarity's neck.

"Uhhh..." she moaned softly, "I feel... so weak...  Must get back to room to..."

Without saying more, she found herself swept up in Celestia's arms even as they raced back towards Rarity's room.  It only seemed like seconds before they were barging in, and Rarity was being deposited on her own bed.

"The drawer... night stand..."

Celestia almost threw the drawer across the room in her hurry to retrieve Rarity's horn.  She could see her pristine white horn in Celestia's hand as it was moved to be placed against her forehead.

"I swear it shall be reunited with my Mistress in just a moment!"

A strange tingling feeling swept from her forehead across her entire body.

"It... it's... done, Mistress Rarity."

"What's wrong, my love?" she asked as Celestia placed a silver mirror in her hand.

Looking at her horn, she realized it had changed from her beautiful white to a black darker than her new hide.

"It's not your fault," she replied, "I... had a feeling... that this was bound to happen...  It will make it all the more precious when I'm return to my former divine beauty."

"What was that *black magic** you used before?*"

"I'm truly sorry you had to see me using that," she replied, "and when this is all over, I swear all shall be explained.  I can only swear to you that I've used that power... only when there's the most dire need to."  Pausing, she added, "But right now, your Mistress... is so tired... worn out from magically enhanced orgasms..."  The golden glaive clattered to the floor from her hand over the side of the bed.

"Rest well, Mistress...  rest easy, my love... I shall defend you to the last drop of my blood!" she declared as she tucked Rarity under the sheets, and then picked up the glaive.  She sat at Rarity's side even as she watched the door.
