Equestria Changed

“You failed me yet again,” Celestia said to her student who was rather distressed by these words. “All the lessons. All the training, and you can’t banish the Nightmare.”

Twilight prostrate herself before her tutor, hoping against hope she could make up for it. But still, her mind was reeling. Her entrance was so sudden, just as how she quickly told her how miserably the spell had failed.

“I-I’m sorry Princess! I-I swear! I’ll do better! I will banish her! If I just look through the Royal Archives, I could probably cross-reference the different titles on reformation to find the most suitable solutio-”

The solar diarch lifted her hoof, making the little purple mare go quiet in trepidation.

“No. You already disappointed me twice. I will have another scholar perform this task. Obviously I overestimated your skills greatly. You will remain here for an indefinite amount of time to self-study and reflect on your shortcomings. You are not allowed to return home as I hardly can reward you by seeing your family while I’m refused to see mine.”

The cowering mare looked up, tears welling in her eyes, “P-Princess?”

Celestia sighed and turned away, moving to the door without saying another word.

She instantly assigned high-ranking scholars to look for a solution to the Nightmare situation. After all, she had her school for gifted unicorns that had many qualified personnel graduate each year. So many other ponies just as promising as Twilight, if not more. She had all the resources at her hooves, including a large library with many spell books to boot. Spell books that could only be found there as well as various books about possessions as well.

This alone made her confident that she would solve the problem within a month and have Nightmare finally eradicated from the face of Equus.

She already had another spell ready, powering her horn and pushing it onto the foul creature.

“No talk this time?” she mocked her, but Celestia ignored it this time, instead focusing on her spell work. It was a more complicated spell than the last, leading her to believe that this scholar was less sloppy in her endeavors than her student. She certainly expected that. After all, she offered a grand reward for whoever managed to pick the right spell.

Then she fired. Another wall of light hitting her possessed sister like last time as the intricate magic washed over her, trying to strip the dark magic from her. It certainly was a good angle. Attacking the parasite directly, plucking it from her like a filthy tick.

She heard the monster scream, giving her some courage as she pulled more into it. So much so that she was exhausted yet again after a full two minutes of upholding it.

Then the magic vanished and Celestia looked up hopefully.

A hope that was quickly crushed as the Nightmare groaned in her position on the wall.

“That hurt! Do me a favor and punch the idiot that suggested that spell. Seriously. I think I will feel that in the morning,” the dark mare complained, something that only agitated the Princess more as she clenched her teeth. Nightmare noticed that, smirking, “What? Feeling agitated about the fact you hurt your little sister? Strange. I remembered that you didn’t care all that much about her. Otherwise we wouldn’t be in this situation, don’t you think?”

Celestia wanted to hit her, wanted to tear into her, but she knew better than that. Instead she calmly counted to ten in her head before turning around and leaving, not wasting her breath on this dark creature.

“Failures happen. Not every spell can work against her. This is a unique case after all,” she said in a shallow way to comfort herself. There were many more spells and she was sure one would work.

Celestia lit her horn, envisioning the mind suppressing spell. A spell that surely would subdue Nightmare and make sure she could destroy the weakened form of the dark mare adequately after she reunited with her sister. It was the ninth spell by now, but certainly promising.

She concentrated on her spell work, guiding her magic and letting it wash over the dark mare. It almost was becoming a daily habit by now. A habit the princess could certainly do without. She didn’t need Nightmare’s snide comments to each failed spell, or even her petty insults or mocking jabs.

All she wanted was her sister.

Her horn powered down again as she looked at her work. This time there was a change as the mare shrunk lightly and reverted to her sister’s self, hanging there limply.

“Luna?” Celestia questioned cautiously.

The mare lifted her head, lightly squinting her eyes, “Tia, is that you?”

“Yes...Yes it is,” she said slowly moving closer.

“Can you move a bit closer still? It is so hard to see you in this damp cell.”

The white mare did so, slowly approaching but staying out of reach, making the smaller mare smile.

“What? Are you afraid of your own sister now? You really shouldn’t be and instead help me down.” she wondered and the taller alicorn had to hold herself back. Not to storm in and give her a hug like she so desperately wanted to as she still had her doubts. Doubts she had to voice, despite her clear wishes to do otherwise.

“I’m sorry. But there is still the chance that you are Nightmare and trying to trick me. I can’t risk it. Not even for you.”

“Such a callous and calculated reply. I am deeply disappointed with you Celestia,” Luna huffed before turning back to Nightmare, making the Princess of the Sun glare. It wasn’t unexpected, but still it hurt to have this monster trying to toy with her heart like this. So she simply glared as Nightmare grinned. “What? No more words today? You certainly get ruder every time. Not even trying to hold a conversation with me. A bit more than a week has passed after all.”

“I don’t need to talk with a dead mare. You will die within a month.”

However. Things turned out differently. In the end a full month passed without the Nightmare being eradicated. This was followed by another quickly. Even the Grand Galloping Gala was passing by, without any positive outlook whatsoever.

Despite Celestia sicking all of her resources on the pursuit to find a solution to this Nightmare mess, nothing worked out.

Every spell, another failure. A few times she thought it was working, but that of course was just the Nightmare playing more tricks on her like the sick twisted being she was.

So the white alicorn’s hope diminished with every following day. She felt restless.

Something that also reflected in her sleep as she tossed and turned, like she did right now.

Her cheeks were glowing, her breath ragged as a particularly juicy dream was haunting her sleeping mind.

Her wings were tense and wide spread, only hindering her movements in her sleep.

In her mind an old memory was dug up. A shameful memory. She tried to suppress it but in a dream that meant nothing seemingly. It all started harmless enough. The strongest heat she ever experienced was forcing her to stay in her chambers for the day. She would have to weather it. To endure it like the dignified ruler she was. Then Luna visited. She seemed worried about her state, or at least that is what she thought about it at the time. In truth she was just nervous for what she was about to do. She pressed her blue lips into hers, kissing her and completely blindsiding her. Normally she would have pushed her sister off and gave her a very stern talking to. But heat-struck as she was she didn’t really stop her. Instead she stumbled back and fell with her back on the bed. It left her exposed and vulnerable for what was her sister about to do.

Seconds later she felt the hot breath of her own sister on her marehood before her tongue lapped at it, making the Princess of the Sun whinny in surprise and pleasure alike. And Luna continued. After the first lick, her sense of holding back seemed to break as she got more eager at it, dragging her tongue right up to where her clit was winking. Celestia tried to stop her, trying to voice her complaints about this forbidden act and reprimand her for it, but the expertise of her tongue was making it difficult for her. Of course she still managed some half-baked “Stop it” and “Don’t’s”, but it hardly deterred her.

Then the tongue pierced her, shoving itself deeply into her. It was feeling as incredible as much as it was scandalous. Her tongue seemed to swipe along every speck of her wet cavern, making the once so dignified ruler a shuddering mess. It didn’t take long for her to cum, spraying her shame directly into her younger sisters face who drank it up fervently until she was satisfied. Celestia herself was too dazed to do anything. Or to notice the embarrassed squeak, the slight scuffling and what seemed like a small panicked discussion near her, before the noises stopped after a while and the door closed, announcing Luna’s departure as she laid in her own shame.

Celestia then gasped, her back arching as she awoke with a start. The pristine white mare felt tense, sweaty, and heated. Her arousal was at an all-time high in that moment. It felt just like the heat back then. Uncontrollable.

“J-Just what is this sorcery?” Celestia panted, her hooves gripping the bed sheets tightly as her marehood felt like it was on fire.

She tried to ignore it. Tried to wait for this heat to cool down but as the minutes ticked by it didn’t change one bit. It only seemed to get worse.

The princess let out a snort of frustration before she laid her hoof on her squishy pussy, edging it into it. She bit her lip, suppressing a relieved groan at the pleasant stimulation. Then she started to move. Rubbing her bare hoof up and down the winking entrance.

She hit her clit while doing this, moaning loudly as a large spike of pleasure shot up her spine. She couldn’t hold it back. Not anymore.

Her hoof instantly picked up pace in her shameful ministrations, the short fur of it tickling along her pink walls blissfully. Her mouth was wide open, letting the sounds of her lust reverberate around her room.

She then remembered the guards posted in front of her doors. Her cheeks glowed as she tried to use her horn for a sound dampening spell, but she never got the matrix quite right as her arousal was distracting her too much from this task.

After a few more tries she abandoned this precaution and simply concentrated on the issue at hoof. But not before using her levitation magic to float over a pillow to her muzzle to moan into. At least her concentration wasn’t disturbed enough to allow her this.

For the next few minutes she proceeded like this. Her hoof was pressed hereby more and more into the squishy mound of her marehood. Each time she hit her clit, she practically screamed into her pillow as she neared her own edge more and more.

Then finally after what felt like an eternity for the pleasure tortured mare, she came.

Her hoof pushed deep against her fleshy pussy lips as she quivered. A string of juices gushed from her pussy and onto her bed, ruining her sheets. High-pitched ecstatic cries escaped her muzzle, most hardly could be muffled by the pillow with how loud she was being. Her entire body was tensing as the relief along with a large wave of bliss washed over her mind. By the end of it she slumped back, laying in her bed panting exhaustedly.

The pillow fell away from her muzzle.

“J-Just what was that? I have never felt that heated since that day. This cannot be normal. This dream cannot...be…” Celestia said, a slow understanding dawned on her, “Dream,” she repeated before her muzzle turned into a snarl. “That bitch!”

Her rage gave her all the energy she needed to quickly stand up. Her magic floated over her regalia, quickly donning the horseshoes, breastplate and crown.

Then after a quick glance in the mirror to make sure she was well-dressed, she made her horn glow to open the doors to her room and trotted out.

Out of the corner of her eyes she could see the two guards that were placed at her door. They seemed flushed and there was something under their...barrels.

The Princess quickly avoided her eyes, fighting another blush as she growled.

“You two, follow me,” she ordered to which the guards flinched, before they saluted. They then walked alongside her uncomfortably.

The Princesses gaze was determined as she walked in the direction of the dungeons.
