Her bed was cold and Vinyl gave a soft sigh. She and Octavia so rarely got to spend a morning cuddling, each of them had their music careers, different as they were. Her hoof reached out, the mare knew better than to use her magic while still half asleep, grabbing her headphones and slipping them on. A gentle tap on the side and her body relaxed into a heavy beat.

Rolling from her bed, Vinyl landed on her hooves and, feeling a little more awake now she was moving, she reached out with her magic and brought her shades over. The bright morning light dulled to a level her sensitive eyes could deal with, she started to move. To the beat of course.

Morning was the slowest time for the star DJ, she made a breakfast of shredded cabbage pancakes, dumping honey on them and devouring one of her favorite meals. She was waiting for it, the note. Tavi always left her a note somewhere and it was always fun to find.

Vinyl worked through breakfast, downed the last of her juice and grinned, it was time to hunt for the note. Not on her keyboard, not on her speaker kit. Then, looking around the oddly bisected house, she spotted something that made her frown. Octavia's cello. She trotted over and squinted at it, using her magic to search it over. No note and worse, where would Tavi be off to without her cello?

Noise outside got Vinyl's attention and she smiled, maybe she ducked out to get something and got distracted. Trotting to the door she opened it and looked out into the bright morning. She could see a whole lot of ponies on the edge of town, and there, among them, was Octavia.

Vinyl's world picked up and her smile grew again until she watched her love, her wife, climb on a train with all the strange ponies. "Tavi…" Vinyl started to run, her hooves pounding as she charged after the love of her life. It didn't feel right and worse, the train was moving! She made it to the station just as the train started to really move and the white unicorn halted in place, glaring at the train. Her headphones had fallen to her neck in the mad dash, the music not matching her emotions anymore.

"Another load off to that commune in the woods. Oddest thing that, but who am I to judge!" The pony in the ticket booth was speaking loud enough for Vinyl to hear and she spun around and trotted to them.

"Where is it going?" The unicorn studied the map at the ticket booth, trying to work out all the places the train could go to from this direction.

The older pony looked at Vinyl. "If'n you want to go along, you could just wait until the afternoon, they have another train scheduled then, coming in from Los Pegasus."

"One ticket please." Vinyl shot her best smile, she would get to the bottom of this. But the old pony just shook his head.

"Sorry, the train is booked, there are no tickets for it. You could ask Miss Dew when they stop here, I am sure she would be happy to take one more. She always is."

Celestia worked the careful spell over her food and smiled when it returned clear. Her sister was plotting something and she knew it. The fun little spell she had put together, the Eggscelent Day, had made her giggle for hours.

"I can't believe you would do that to Luna." Twisty, however, hadn't been enthused about the prank. "I don't want either of you to think of laying eggs as punishment."

Celestia couldn't stop herself reaching a wing out to hug the mare. Her heart twisted a little with the tone in her lover's voice. "I didn't mean it as punishment, I actually worked in a little bit of the trick you use on me, but as a spell. Each egg she laid felt better and better."

Twisty perked up a little at that, her smile returning. "Still, why not just get me to go and fill her with eggs again?"

The alicorn snorted and scooped up some of the delicious-looking cheesecake. "Because that prank is done and… wait, you are ready to lay more?" Celestia had a little bit of shock at that.

"Not yet, but soon. Would you like them again?" Twisty nuzzled the wing wrapped against her side, giving the feathers a little preening with her delicate teeth.

Celestia sighed. It had been far too long since a lover had preened her wing. She extended it a little further and enjoyed her cake in silence. It was easy to close her eyes, relax and let the wonderful changeling continue. Something nibbled at her mind, even as Twisty did her wing, and at last her head lifted and she looked at the changeling. "When did you learn to preen wings?"

There was a little shock, her wing was now inky black and Celestia could see a spell unfolding on herself, it was part disguise spell and part shield. She tried to stop it but real power surged in it and the shielding part seemed particularly tuned for her own magic. Luna was laying where Twisty had been. "What's the matter, sister, don't like the idea of becoming Nightmare Moon?"

The spell rolled from Celestia's wing across to its twin and also down onto her body. It wasn't actually changing her, but as she watched her fur and feathers, mane and tail were changed to look like the dread creature her sister had been. "I am so going to get you back for this." Celestia felt the weight of a helmet settle onto her head and more, her teeth now feeling pointed and sharp. "How real is this illusion and how long will it stick?"

"It is real enough for ponies to feel your fangs." Luna giggled as her sister was completely remade into the dark queen with… a little extra.

Celestia shifted and adjusted herself, she felt odd. Peeking down to her belly revealed why. "A stallion? Really?" Luna was too lost to laughing by this point and Celestia decided something. "Well, former pawn of darkness, you let Nightmare Moon in once…" The disguised alicorn of the sun leaped and landed on the startled Luna's back.

Luna felt a moment of panic and she tried to get up, but Tia had her forelimbs trapped against the ground and, in her haste, she had lifted her plot only. A terror seized Luna, a terror and a forbidden delight. She shouldn't want this but, in all honesty, hadn't she really sown this seed? The feel of the powerful, Dark Queen's body pressing down against her made her shudder, in one way it was very kinky to have her own dark past come back to her like this, in another it was astoundingly kinky for her sister to mount her.

"You have wanted this, haven't you, little Lulu?" Celestia pushed forward, her body was not quite sure of the angle and she struck the mare's perineum. The black shaft was oozing already, trying to prepare a mare for breeding, the slick lube made the length slide up to Luna's tail-hole. "This will do. After all, we wouldn't want a real foal out of this, or would we?"

The slimy-wet shaft pushed at Luna's plot, the pressure growing by the second before Celestia pushed inside, the hefty bell-end stretching Luna's pucker and working inside. Luna lifted her voice in a loud moan. Her sister was doing something the Princess of Dreams had only ever fantasized about before. She was dripping with lust now and tried to push up and back, only to find Celestia, or Nightmare Moon, had braced her shoulders down and was in full control. The normally white flanks tensed and drove forward and down, getting a happy sigh from both of them. Luna could feel the big pole, spewing a constant stream now, making the passage slick and ready for more.

Celestia drew back a little, hearing a whimper from her sister. "You want it all?" Luna nodded. "Tell me, tell me you want all of this in your hot rear." Luna shied from the words for a moment. "Tell me or I will stay just like this all day."

It broke into a part of Luna she never thought would find light, not the light her sister bore. "We want you, Tia, we want you inside us and we want you around us… Please fill us… me." Luna was panting, her eyes wide at the words she had spoken. She felt a kiss on her cheek, then a fanged nibble at one ear.

"You woke this in me, sister-mine." Celestia whispered into the panting and shocked Luna's ear, giving the pinned alicorn a moment to remember that dream before she shoved forward, shoving the heavy, magic-given pony-penis all the way down that clutching colon, her thighs pressing tight against Luna's plot. "Sister… mine…" Celestia got the words out in a huff, this was getting a little too exciting to think too clearly and so, like many stallions before her, Celestia started to pull back and shove home again.

Luna closed her eyes, smiling widely as she felt the tension drain from her mind, seemingly into her rump. The friction was well smoothed, but it stirred her body. With her pulse beating a million miles a second, Luna gave a loud moan as she lost herself early to the pleasure, her mound untouched but clutching and gripping at nothing.

Celestia almost lost her pace, she felt the already tight passage gripping and squeezing at her, and the moan the accompanied it told her all too well that Luna had already found her pleasure. Knowing the prankster was trapped in the grip of pleasure, Celestia lined her new fangs up at Luna's ear-tip and bit down.

The slight pain did nothing to detract from the pleasure in Luna's body, her lust-wracked brain took in the new information and decided it must be pleasure too. The world was huge and tiny, dense and sparse. Everything narrowed down to her tail-hole and then spread out again to encompass her whole body. Luna's tongue lolled out and she felt her most wonderful sister keep up the pace, fighting past the tight grip she was putting on the big shaft.

"The question… is my little… Lulu… can I get… another… from you?" Celestia was pumping in long, broad strokes, driving her swelling pony pecker deep into the other alicorn's rear. Luna's orgasm did nothing to boost the lubrication in her rump but it wasn't needed, Celestia was leaking enough for the both of them. The smell of excited mare, of her excited sister, was welcome to Celestia, her nostrils flaring at the scent of arousal leaking from the empty mound below her pistoning shaft.

Luna was in bliss, she shuffled her back legs a little to try and make sure she wouldn't lose her position and this earned a harder than normal shove from Celestia. Something was building, she could feel it. There was magic and pleasure both rising in both of them and Luna, right then, didn't care about what the power would do.

Celestia felt it too, her excitement at the impending climax and final claiming of her sister only made her more frantic, more firm in her thrusting and bucking. Her crescendo started and her body seemed to evolve the humping into something almost elemental in its force. An ache started in her balls, the balls she hadn't ever had before, it was an emptiness at first, a need for something. Then the need was met and she felt the ache of emptiness shift and grow into fullness. Then her world exploded, her horn too.

Light filled the room, viciously bright to the Princess of the Night, but Luna's own horn lit, darkness spreading out into the light, twisting with it and blending with it. Luna felt the first hot spray, deep in her rear and lost herself to pleasure for a second time.

The magic wrapped around them, it banished the Nightmare Moon enchantment but strengthened the one that 'enhanced' Celestia so she could finish. Wings spread wide, Celestia's voice rose to meet her sister's, the pair moaning and calling to their elements and each other, the power in the room intensified as each was locked into their orgasm, Celestia pumping more and more hot seed into her sister and Luna clutching and milking at the organ, her body on fire with the need for more of the scalding heat of both her sister's issue and her magic.

The pleasure wouldn't last at that level forever and slowly, with many more little jolts of pleasure, both mares slowly came down from their high. Luna's body slumped all the way down to the floor and Celestia followed, her length still lodged deep in the dark plot.

An odd sound met their ears and Luna twitched her pierced ear as she and Celestia both turned to see Twisty, clopping her applause. "Finally, and I must say, Celestia, that really suits you. Me next!" The changeling raised a hoof and giggled.
