Nightmare Moon expected to find the changeling queen posed seductively on the bed when she next returned. What she did not expect was that the changeling would have taken her shape.

For a long moment she simply stood at stared at the familiar jet black coat, broad ebon wings and long, elegant horn. "What foolishness is this?" she finally said.

"A whim, I suppose. Your form is quite pleasant to take. You are very beautiful, you know."

The Nightmare's eyes narrowed. "I cannot be swayed by simple flattery."

Chrysalis shrugged. "All the same, it is nothing more than the truth. Do you think I would normally lie with a pony who held me prisoner? Indeed, do you think I lie with ordinary ponies at all? You are worthy of me, Queen Nightmare."

Nightmare Moon stalked through the bars, dissolving to smoke in an instant as they slid through her, then reforming a moment later. "I must admit that you look good as me." She grinned at Chrysalis. "Is this some scheme to gain my love, perhaps?"

Chrysalis laughed. "If I could feed on self-admiration I would not have gone hungry these past days. But no. I suppose I could see it working, if somehow you could be unaware of the deception, and direct true admiration towards me. But how would that be possible? Only true emotions provide my food, and you know what I am. You do not love me, not even in this guise."

"Indeed not. But I do desire you, changeling."

"Oh yes." Chrysalis licked her lips. "Come, let me sate your desire. I have taken a page from your own book, see?" She rolled over, revealing the stallion's cock between her legs.

"How unoriginal," sneered Nightmare Moon, but she took a step closer. "You merely copy my own methods."

"And why not, if they're successful methods? I am a changeling, imitation is our greatest skill. Though I might show you a new twist or two. Come. You've said you desire me. Let us sate our desires together." She beckoned to the Nightmare, who climbed into the bed eagerly enough.

Chrysalis wrapped her forelegs around Nightmare Moon and pulled her in for a kiss. Their lips met, twinned as if each kissed a mirror, tongues swiftly twisting together, caressing over sharp fangs, the kiss growing in passion and ferocity the longer they held it. Chrysalis shifted to lie alongside the Nightmare, tangling their legs together, folding her wings over her mirror image.

Nightmare Moon growled softly into the kiss, moving to roll on top of Chrysalis, but Chrysalis resisted, seeking instead to roll over and pin the Nightmare beneath her. They wrestled back and forth for a time, rolling around on the bed, the heated kiss turning into a series of even more heated bites and nips. Chrysalis got on top for a moment, but Nightmare Moon used her mane to help her pin Chrysalis only seconds later, holding the changeling helpless beneath her. Chrysalis could not retaliate in kind, for her mane was merely an imitation of the magical expression of alicorn power that made up Nightmare Moon's umbral mane and tail.

With a grin, Nightmare Moon straddled Chrysalis and rubbed herself against the erect black cock that the disguised changeling sported. She made a humming sound of pleasure as she did so, her eyes half closed. Chrysalis let out a low moan and gave up her struggles.

"Ha ha ha! You are mine now, creature. I shall once again show you a world of pleasure beyond the ken of insects such as you."

"I am not... ohh... oh gods." Chrysalis tried to say something in response, but as Nightmare Moon positioned herself, her pussy rubbing against Chrysalis' cock, the changeling found it almost impossible to speak coherently. Nightmare Moon laughed and continued her assault on the changeling's shaft, spreading her juices liberally along it.

Chrysalis moaned again, almost whimpering. Her ears went flat back, then suddenly she growled and tried to roll Nightmare Moon over. Nightmare let her, but just kept rolling, there was room enough in the big bed, and she once again ended up on top. She kissed Chrysalis hard, forcing her tongue into the changeling's mouth as she pinned her down. They were a strange image, perfect duplicates kissing passionately, twins locked in an erotic embrace.

When she broke off the kiss, Nightmare Moon grinned gloatingly. "I will always win, insect. But don't worry. I'll give you what you want." She rubbed herself on the changeling's ebon black cock again. Chrysalis shivered and whimpered softly, a sound of helpless need. Nightmare Moon laughed and lifted herself up, putting her pussy against the tip of Chrysalis' cock. The changeling lifted her hips, trying to push into Nightmare, and she cooperated willingly enough, feeling the hard length of Chrysalis sinking into her. "Mmm. That is very good. You make a good imitation of me, I must admit." She tipped her head back, savoring the sensations as she took the changeling's cock deep inside her.

Chrysalis moaned softly and squirmed beneath Nightmare Moon. Her jet black wings were flared out and fluttering, her eyes closed as she felt the warmth of the Nightmare's body closing over her. Nightmare Moon lifted back up teasingly, pulling almost entirely off her cock. Chrysalis lifted her hips, pushing up into Nightmare Moon insistently, her hooves coming to rest on the other female's hips, pulling her down. The Nightmare chuckled, a rich, throaty sound, but cooperated once more, letting Chrysalis pull her hard against her.

They settled into a rhythm, Nightmare Moon lifting herself, then letting Chrysalis pull her down, Chrysalis rocking her hips steadily, thrusting up into the mare whose image she had copied. Nightmare Moon bent over and kissed Chrysalis again, their tongues locked together even as their bodies bucked against each other, both seeking fulfillment.

As the Nightmare's motions became faster and more frantic, Chrysalis suddenly rolled her over again, keeping their hips locked together, and pinned Nightmare Moon beneath her. Nightmare Moon hissed up at her and tried to once more keep rolling, reversing things again, but as Chrysalis thrust down into her, pumping hard and deep, Nightmare stopped struggling. It felt so amazing she found she didn't care who was on top. Though when her mirror image once again kissed her, she bit at Chrysalis' tongue, then pushed her own tongue into the changeling's mouth forcefully, wanting to remind her of who was in charge, whoever might be on top. Chrysalis growled into the kiss and thrust harder, pounding into the Nightmare with rough, primal strokes.

Nightmare Moon let out a shameless moan, writhing under Chrysalis. She brought her hind legs up and locked them around the changeling, her front legs also embracing her, pulling her mirror image tight to her, kissing her with frantic passion. Chrysalis responded with equal passion, her tongue twisting with the Nightmare's, her hips pumping, taking her hard and fast. She broke off the kiss after a moment, panting rapidly, and pressed her muzzle against the side of Nightmare's neck. Nightmare Moon lifted her head and nipped at Chrysalis' ear, and Chrysalis responded in kind, nipping and biting at the base of the Nightmare's neck. She shuddered and bit down harder as her peak began to near. Her cock drove into Nightmare Moon with wild abandon, each stroke sinking as deeply as possible, as fast as possible, primal and powerful.

The dark queen answered with equal fervor, her fangs digging into Chrysalis' ear, her hips lifting to her thrusting, her body clenched around the pounding cock, seeking to wring every bit of pleasure from it.

Chrysalis hissed in pain at the bite in her ear, but did not stop. She drove her cock into Nightmare Moon with increasing intensity, until finally, with one last convulsive thrust, she came. Spurts of hot seed flooded the Nightmare's body, and she shuddered, feeling it fill her. She tore her fangs free of Chrysalis' ear in a shower of blood and snarled, "Don't you dare stop!"

Chrysalis snarled back, but obeyed, continuing to thrust hard and fast, while Nightmare clenched tightly around her, tensed, her back arched, her whole body trembling. Then at last she came, crying out in bliss as pleasure crashed over her.

The pleasure ebbed and she went limp. Chrysalis relaxed as well, coming to rest deep within the Nightmare's soaking, semen-slicked folds.

For a long time there was silence as the pair caught their breath and basked in the glow. Neither would admit it out loud, but both had found this night's experience to be intense beyond anything they'd known before. Other lovers seemed to pale before the intensity—the ferocity, even—of their attraction.

At length, Chrysalis rose, pulling her softening cock free of Nightmare Moon below. She stepped from the bed and, in a flash of green fire, returned to her own form. Nightmare Moon stretched luxuriously, watching her with an indulgent smile. Then a small frown crossed her features. "How is it that you have the energy to transform? You should be nearly starving. You've said yourself there is no love for you here."

Chrysalis chuckled. "It took you long enough to notice! Changelings feed on positive emotions. Love is the strongest, and fuels our magic with mighty power. If I had love to feed on I would not be long in this cell, I assure you. But lust, your Majesty, is a positive emotion as well."

"I see." Nightmare Moon rose from the bed, her eyes narrowed. "So all this was a sham to gain the energy of my lust?"

Chrysalis smiled a sly smile. "Perhaps. Yet I meant it when I said that you were a lover worthy of me. And tell me true, Queen Nightmare, Envoy of the Moon, Keeper of the Sun, Ruler of all Equestria, have you ever had a lover more worthy of you than I, Chrysalis, the Queen of the Changelings?"

Nightmare Moon considered this. As she did so, she felt the wetness of their lovemaking oozing down her hind legs, and remembered the primal power that had come from their union. She smiled a sharp-toothed smile. "I suppose it is true. I will not call you my peer, but I will admit that you are more... worthy than other lovers I have had. But do not think to escape, changeling. I will not relax my guard simply because you are a pleasing mate."

Chrysalis snorted. "You relax your guard already, simply by being here in the cell with me. But no, I have no plans to escape. My plot to use Shining Armor and the saccharine Princess of Love to gain power has already failed. I must resign myself to a lesser place than on your throne. But why not enjoy myself while I can? Your lust is delicious, I have seldom tasted its like. And your regard is not unpleasant either."

Nightmare's eyebrows arched up. "My regard?"

"It is a positive emotion as well. You admitted it yourself, you have come to consider me worthy. I will not claim to be your peer, not now. Someday, perhaps I shall be." She gave Nightmare Moon an irreverent wink. "I will not pretend to wish anything less than absolute rule! But for now, why should I not bask in your lust, enjoy your regard, and consider myself fortunate to be the second most powerful being in Equestria?"

Nightmare Moon laughed. "You are bold, Chrysalis."

"Would you respect me if I cowered and cringed before you? I'm sure you've seen plenty of that. Such regard born purely from fear or from sycophantic power seeking is empty, hollow. I have tasted how hollow you were, Queen Nightmare. You were a hungry, empty shell. Do you feel empty now, with my seed within you?"

Nightmare Moon snorted. "I suppose you have a point. The worship of my subjects is enjoyable enough... but I will admit it does pale swiftly, yes. But what are you proposing? It sounds as if you seek some form of alliance?"

"I seek nothing more than I have now, oh Nightmare. I seek to be your lover. To sate myself with your pleasure. To dine upon your regard, and to give you pleasure and respect in return."

"That is all? Forgive me if I fail to believe your... modest ambitions."

Chrysalis laughed. "Oh, I seek also the opportunity to overthrow you, but I must admit that after recent nights, I won't seek it too swiftly. Having you in my dungeon might be pleasant, but I would probably be required to kill you in order to actually take over your kingdom, and that would be quite a shame."

Nightmare Moon stared at her for a moment, then broke down in almost hysterical laughter. When she caught her breath again she said, "So you want to be my lover, while openly admitting you'll cheerfully kill me if given the chance?"

"You seem to want to be my lover while keeping me a prisoner in your dungeon. We are hardly conventional people, Nightmare Moon. We are not going to have a conventional romance."

"Romance! Pah. Romance is for foals with their heads full of fluff. But you are... amusing, shall we say. Ah, to Tartarus with it, why not? Come! You have made a royal mess of us both this night, let us go clean ourselves, and slumber in better luxury than we can have here!" Her mane reached out, wrapping around the changeling, pulling her into shadow. A moment later, Nightmare Moon herself had folded into the same shadow and both were gone, teleported off to her luxurious bathing chamber, where no doubt further erotic interactions would take place as they washed one another.

And in the cell just down the hall, a tired-looking pink alicorn lifted her head and smiled a small, secret smile.
