The Mirror

Canterlot

Royal Library Entrance

"This is so boring!" How long until the switch?" asked the guard at the Library entrance.
"Soon now quit your whining and do your job." older guard answered.

In the distance, somepony was approaching the door with someone behind him.
"Who or what is that?" younger guard asked.
"Expect them to be the hostile defensive position!" ordered an older guard.
Both guards raised their shields and swords.

Twilight stopped in front of the guards who had spears ready.
"Finally next time don't grab me with your magic and run like your life depends on it."
"Shush. This is important. Oh... and hello to you Sunspot, Silver Line. We are coming to do some research it's important could you let us in?" Twilight asked trying to hold her excitement back.

Both guards lowered their weapons and bowed.
"Of course Princess Sparkle. Sunspot open the door." ordered an older guard.
"Yeah yeah... and I thought something would finally happen, but no!" Sunspot mumbled to himself while opening the door.

"Thank you. You two can take the rest of your switch of we're going to be okay." Twilight told to the two guards.
"Thank you, Princess Sparkle." Both of the guards told in unison, bowed, and left.

Spike and Twilight walked through the halls of the library and they noticed the wing which holds all of the known lore and magical items from dragons and dragon lands. There were many books on the table open with bookmarks here and there.
"Seems like Celestia and Luna have been researching your mark. Maybe we should take a peek too." Twilight commented and lead them inside.

Spike decided to look around. There were a tremendous amount of expertly crafted armors and weapons for dragons. While wondering and looking around he arrived at the tall oval-shaped mirror. Its frame was carved from some unknown tree species. On the right side was a dragon with four horns holding a giant sword that looked like a living flame. On the left side was a dragon with four horns but his horns all pointed downwards and he was holding a sword too but it looked like it was made of living magma.
"That dragon on the right side looks familiar but that one on the left side gives me the chills. And those weapons what are they." Spike thought while examining the mirror.
"Twilight! You know what this mirror here is?" Spike yelled so Twilight could hear him.
"That old thing? I don't really know Celestia told she and Luna found it sometime after the war with Sombra. If I remember correctly she told me it was called the Mirror of Blood. Weird name in my opinion. Carvings around it don't have a hint of reference on blood, but hey it was made by dragons and their culture is still a big question mark to us." Twilight answered still going through the pages of books.

Spike decided to look closer and there was text.
"What's this? There is some sort of text in it" Spike said and started to clean the dust from it.
"Well it's old I give it that. I think I can make out what it says"Sanguis inveniet eorum" Huh... Wonder what does that mean?"

Not long after uttering those words the text and mirror started to glow bright red. After the glow faded away in the mirror was a dragon looking like Spike but it was a female. The odd part was an image in the mirror wasn't copying his movement rather he or she, in this case, was looking panicked and beating the mirror with both of her hands and looked like she was screaming.
"What!? Is this some sort of magical trap? Twilight!" Spike yelled while running to get Twilight.

"Did you break something again Spike?" Twilight asked angrily.
"You need to see this!"Spike said and grabbed Twilight's arm and dragged her to the mirror. Upon arriving at the mirror Twilight was dumbfound. Dragoness in the mirror was still pounding the glass from inside.
" How is this possible? That mirror is old, very old who knows how long she has been trapped in there." Twilight commented and started to charge her magic up to scan the mirror. Dragoness in the mirror was crying and by the looks of it screaming.

"I feel the power in this mirror but I can't feel her inside this mirror." Twilight commented while trying her best to pinpoint where the dragoness was.
Spike placed his hand on the mirror and the dragoness mirrored him. It was like their hands were touching but there was a mirror in between them. "Hold on there. Twilight will get you out there." Spike said trying to comfort her. Not knowing if she can hear him.
Image of the dragoness started to ripple "The magic power is starting to diminish." Twilight said. Dragoness gave a small smile while crying and in a blink of an eye disappeared. The mirror was now reflecting Spike and Twilight like a normal mirror.

"What happened?" Spike asked.
"Magic energy that was holding her here was used up. I have a theory either this is some sort of communication device or it is a prison for this dragoness whose image was in it. What did you do to activate it?" Twilight asked.
"I... I don't know Twilight there was a text on it I just read it and then this happened." Spike answered.
"Maybe it was some sort of the spell placed on those letters which activate when read. Please show it to me." Twilight pondered.

"Sure it was right here." Spike pointed at the sword that the dragon on the right side was holding, but there was no text in there. "How it was right there on the sword. How could the text just disappear like that." Spike panicked.
"This can't be a coincidence. First, you being some sort of champion to a dragon god and now this. We need help from the other Princesses if we are to figure this out." Twilight commented.
"This is about dragons and we got former and current dragon-lord as guests here maybe ask them to?" Spike asked.
"Good idea. You write to Lord Ember I'll write to princesses." Twilight answered and they got to their assigned tasks.

Canterlot

Royal Dining Hall

Hour Earlier

"So once more just so I understood. You need Spike's seed for this potion to remove your immortality so you can have foals of your own because your mother made a mistake so long ago casting this spell on you?" Candance asked.
Celestia and Luna just nod. "Yes and hopefully I find somepony as gentle and loving as Spike." Celestia commented.
"Indeed we to see Spike as admirable and hope someday find someone as he is." Luna added.
Cadance narrowed her eyes. "This love energy there is no mistaking it. Both of them have romantic feelings towards Spike just like he does towards them, but they haven't broken out of their shells yet Celestia is more obvious, but Luna is hiding her feelings better." Cadance thought.

"Aunties please no more lies with me. Have you forgotten my special talent already?" Cadance asked.
Both Celestia's and Luna's cheeks burned bright red. "I... eh... we can explain." Celestia stuttered.
Cadance gave reassuring smile. "Auntie you don't have to explain anything to me. It's my job to help people found their special somepony or in this case somedragon." Cadance finished.
"So you don't hate us for having these feelings?" Celestia asked.
"Auntie your my family sure we have our ups and downs but no matter who you choose as your special somepony I won't hate you two. Besides, it may be rare but there are pairs like these. I helped a certain pair here in Canterlot a couple of weeks ago you may even know her, your head maid Cream Heart. And thanks to magic health care we have nowadays it is a very high chance that foals between blood relatives will be born without any problems" Cadance answered.

"So what are you suggesting we should do now Cadance?" Luna asked.
"For now nothing. We need to first resolve this mark situation. After that, you two should have a private talk with him." Cadance answered.
"That's it? That sounds a little too simple and easy." Celestia responded.
"Whose the specialist in love here? When was the last time you two pursued a romantic relationship and not just sex? Love is simple and complex at the same time. Usually, the simplest ways are best to use." Cadance told them.
Celestia and Luna both sighed. "Well we have been out of the game so to speak for a long time, but..." Luna said blushing slightly.
"But you are probably right after all you are alicorn of love. After this situation is sorted out we will talk with Spike." Celestia finished for Luna.

"Now that's out of the way I need to go see how my daughter is wrecking her father's nerves." Cadance said.
Cadance did have a chance to exit the room when a letter appeared in front of the three princessess. It had the insignia of Twilight on it.
"What could Twilight want at this time of the day?" Celestia asked.
"Maybe she already translated the recipe." Luna said.
"Twilight is smart but even she couldn't pull something that large in a couple of hours." Cadance said.

To Princess Celestia

Princess Celestia we need your help at the library in the dragon wing. We were about to get a headstart on our translation task, but while walking we noticed open books in the dragon wing of the library and I decided to see what you had found. Did you know that there is a trial to prove that drake is ready for adulthood? All he has to do is survive long enough in a fight against his father. There is so much information about dragons here, but I'm getting sidetracked again. Spike managed to somehow cast a spell on Mirror of Blood and there was a dragoness in it who seemed like she was trapped in there. Who knows how long she has been in there. We need help figuring this out can you, Princess Luna, and Cadance come to the library?

Your Faithful Student
Twilight Sparkle

Celestia was lost in thought he had always known that the mirror she and Luna found after the fall on Crystal Empire was a magical artifact but never managed to do activate it so to speak. And now Spike had accidentally managed to do so."Luna you remember the mirror we found after the fall of Crystal Empire?" Celestia asked.
"I remember it. Now that think about it the remnants of magic energy it had are similar to what Spike showed during the fight against his darker part." Luna answered.
"Aunties what mirror are you talking about?" Cadance asked her interest getting the better part of her.

"I'm talking about mirror what we found with Luna after our war with Sombra. After the empire vanished in thin air. I, Luna, and other members of our army started a search for survivors. I and Luna found an odd dark red stone slab. It was approximately at the location where Crystal Castle was. There was a figure carved in the slab it looked like a dragon but it was all deformed. There was text over the dragon "Omnes autem ne in chao ". Loosely translated it means."
"All will drown in chaos" said Luna and Celestia nodded
"So Sombra had some connections with Eris?" Cadance asked.
"A sound theory but highly unlikely. We defeated her long before Sombra showed up. And also Eris would have seen Sombra's rule as boring as ours. Sombra wanted what we too wanted order but under his iron grip." Celestia answered.

"The room under the slab looked like some shrine. There were some dead ponies so Sombra either sacrificed them or used them to power blood magic. After some time of searching and going through some mad writings, we found Spike's egg and that mirror. There were also lots of eggshells so I'm sure that Sombra experimented with lots of them and Spike's egg was the only one to survive those horrid experiments." Luna continued the story
"The mirror emitted an odd magic signature it felt familiar yet terrifying our soldiers nicknamed it Mirror of Blood and the name kinda stuck. We really don't know if the mirror has some real name, but the bloodied corpses our soldiers witnessed in the chamber gave them that idea. We tried many different tests to get the mirror to react to magic but nothing we did managed to cause a reaction. So it just was left to royal archives to gather dust." Luna finished

"Indeed, but it seems Spike managed to activate it by either with his presence or casting a spell on it. And According to Twilight, a dragoness appeared in the mirror. Twilight said it was like she was trapped inside the mirror. She has asked our help on the matter to solve the problem." Celestia told them.
"What! Did he manage to activate it? Does he even know anything about the mirror at all? How..." Luna asked bewildered about Spike's latest deed.
"This sounds really important maybe we should leave at once and talk on the way." Cadance interrupted Luna
"I agree with Cadance we should go and see what my son has managed to get himself mixed in." Celestia answered. Luna nodded and the three alicorns left the dining room heading towards the Royal Library.

Guest suites Ember's room.

Ember was crying in her bed holding tight the pillow so no one would hear her sobs.
"Why? Why Draco? A Drake who is something special to me one who I could possibly have a clutch someday already has someone?." Ember was thinking to herself while sobbing.
There was a loud knock at the door to her room and a strong yet concerned voice could be heard behind it.
"Ember my sapphire are you okay? Could I come in?" Torch asked not demanded.

Ember got up from her bed walked to the door and opened it to see concerned Torch and Smolder both standing there.
"Is there a problem?" Ember said trying to sound strong but Torch noticed the change in her tone immediately.
"Smolder could you leave us two alone for a moment. Family business." Torch said.
Smolder nodded. "If you need any help you can always ask for help no matter the problem Ember. Remember you have friends and family that loves you." she said and left father and daughter alone.

Torch closed the door and once it was done Ember leaped into her father's arms crying. "I wondered why you left in such a hurry and wanted to be left alone." Torch said with love and care in his voice.
"Why dad? Why it hurts so much? I'm used to pain on my training but this feels so bad." Ember asked while holding her father close.
"Oh my sweet sapphire. I knew this day would come someday. I hoped that your mother would be up during this moment but her great sleep hasn't ended yet. I'm not good at the matters of the heart. Cynina was always the one with more knowledge about this." Torch told her daughter.
"Spike was special I hoped that someday he would join with me as a mate and help me to guide dragons towards new and better future. It's like the world hates me and demands that I spent my days alone." Ember explained while sobbing.
"Oh... Ember. Do you really love him that much?" Torch asked.
"I do father but it's too late now. I missed my chance." Ember said.

"What if I told you that you'd didn't miss your chance yet?" Torch asked her daughter.
"What do you mean father. He is in a relationship already." Ember said with a small hope returning to her
"Well it's rare nowadays, normally we dragons hoard treasure but there are some who hoard other things." Torch started her explanation.
"What are you getting at father?" Ember asked.
"Well you see back when I was about your age. I to hoarded this type of treasures. I had my own harem of dragonesses. Your mother was one of them. And before you start yelling or anything it was more of adventurous adolescence. I didn't force anyone to be with me they just did and after some time they left on their own way. The only one to stay with me was your mother. We were pretty much in love and during my harem days I spent most of my time with her rather than other girls." Torch explained.

"So you're saying I should join his harem? But what if he just decided to toss me out? I don't want that kind of relationship I want to love him and him to love me back." Ember told her father.
"Ember. Spike may be raised by ponies but he is a great dragon and strong one to even so now thanks to his status as a champion of Draco. I haven't met Dragon with a big heart like his in a very long time. He treats all of his friends as a family. He is already in a relationship with two-element bearers. You should talk to him and not as the dragon-lord Ember but as dragoness Ember. And if you decide to join into his harem I'm certain he loves each of you girls equally and with great passion." Torch told her.
"I... I don't know. He does treat me as a family member even now without me asking anything in return. Perhaps I should talk with him at..." Ember was interrupted as a green ball of fire and a letter dropping from it to the floor with text reading From Spike to Ember on it. Ember picked the letter up opened it and started to read it with his father.

Hey, Ember it's me Spike I'm in a kinda spot right now and need some dragon help from you and your father.
You're maybe wondering why I need dragon help well there was this ancient mirror "Mirror of Blood" Twilight calls it has some draconic carvings in it and I kinda activated it and now I can't seem to reactivate it. So I figured maybe you or Torch know something about it as you know your raised in dragon lands and I was raised by ponies so my knowledge about our kinds culture and history has a pretty big cap on it.

Hope to see you soon here love Spike

PS. After all of this is done and all maybe we could have a walk or lunch or something and talk about stuff you know only if you want of course my Lord.

"Well look at that you can't say destiny doesn't have a hand on this one. There's your way to talk with him alone." Torch said with a wide grin.
Ember was blushing hard. "Dad! We should go and see what they need help on maybe it is important." Ember said and started to fly towards Library.
"Sigh... Young love. Well, I should catch her I'm pretty sure she doesn't know where Royal Library is for that matter I hope it is still in the same place." Torch talked to himself and started to fly after his daughter.
The princesses and dragons met at the door to the library

"Royal Sisters, Princess Cadance. Your both here too. Did Spike send a letter to you too asking for help?" Torch asked.
"Torch, Lord Ember. Good to see you again. And no my son didn't send a letter to me my student did I take it they did send them at the same time. Let's go and see what is this problem of theirs." Celestia answered.

Once they arrived into the wing where all the dragon lore of Canterlot was Twilight was taking notes while studying the mirror with Spike. Once she noticed they had arrived she got up and welcomed them into her temporary lab."Princesses, Lord Ember, Lord Torch good you're here come here we're running some tests but nothing seems to work on it yet." Twilight explained while looking through her notes.

Once they arrived in the room with the mirror Torch looked like he had seen a ghost. Ember noticed this.
"Something wrong father?" Ember asked.
"Where did you get that?" Torch asked.
"Oh this mirror princess Celestia and Luna found it shortly after and Spike here managed to activate it shortly there was a dragoness in the mirror who looked a lot like Spike. Tell me Torch, Ember is this some kind of trap for a dragon?"
"You have no idea what you have in here do you?" Torch asked with a hint of fear in him.
"Torch you know something about this mirror?" Luna asked

"I really don't know all about it. We may have some old books in Dragon Lands about it. I know stories my father told me about it. That is an ancient artifact of dragons called Mirror of Brothers. It was crafted by two brothers. Whose images are crafted on the mirror frames. I thought it was either destroyed or lost to time." Torch explained.
"Who were these two craters and why is it so special?" Celestia asked.
"Sigh... the other you know him as Draco the first dragon he is on the right side holding his sword "Purifier" and his twin brother is a secret we don't like to talk he is a shameful mark in dragon history." Torch continued.
"I always thought that Draco didn't have siblings I haven't found any text of this twin of his." Twilight spoke.
Toch shook his head. "As I said it is a shameful mark in dragon history. His name Exitium he's also known as Dragon God of Destruction on the frame he is holding his sword Devourer. Legend says that the mirror is portal to his realm what is also his prison." Torch finished.

"If it's a door to another realm how did Spike activate it also how is it possible that there was a dragon on the other side of the mirror and not some god." Twilight asked while scripting as fast as she could the information she was getting.
"That was what I'm worried about. Legend says that the mirror works only one way. If you enter you can't come back from Exitium's realm. Why there would be a dragon in his realm?" Torch said.

"Can we do anything for her?" Spike asked worry in his voice.
"Sadly nothing we can do for her yet. And I think we shouldn't do anything there is an ancient prophecy about the return of Exitium. If he is to return to our world we would be engulfed in chaos. And not in a funny little crazy way Eris did back in the day something far worse and deadlier." Torch answered.
"Omnes autem ne in chao" Celestia said.
"Where have you heard that Princess Celestia? That is something The Cult of Chaos uses."
"When we found the mirror it was inside a hidden chamber in crystal empire." Celestia said
"As much as I like to talk about the history of our race maybe we should retire for the rest of the night and talk about this in the morning." Torch said.
"But..." Twilight tried to talk but Celestia interrupted her.
"A wise idea Torch. We'll talk about this in the morning" Celestia said.
Reluctantly Twilight agreed. "Fine but I want to be the first to write bout Exitium pretty please Torch. Come on Spike lets get to sleep." Twilight said.
"I think I'll sleep in my old room if it still is the way it used to be? Is it Mom?" Spike asked
"Yes it is my dear. You still have the key?" Celestia asked and Spike nodded.
After all, was said all of them retired to their bedrooms.

Spike's Room.

After getting to his room locking the door Spike collapsed to his queen-sized bed. Undressing so he was in nothing but boxers. "I do hope mom hasn't found my stash." Spike said to himself while rummaging through random stuff under his bed until he pulled an old Playpony magazine from there.
In the cover was a muscular male pony with five different female ponies in see trough Saddle-Arabia belly dancer outfits that left very little to the imagination. Some of the girls even had sexy piercings on them.
The title of the magazine was "Gror and harem mares" with texts like "Gror teaches them how a mare should obey orders" and other domineering texts.

Little Spike was getting into attention while Spike was reading through the magazine."I'm such a dirty drake, but who wouldn't want multiple mares to do whatever you order them to do." Spike thought to himself and started to move his hand up and down on his shaft. He remembered last evening when Twilight helped her by giving him a handjob. Spike was imagining him and Twilight going at it. His hand moved faster and faster bringing him closer to his release.
"Gods yes take it Twilight." Spike spoke to himself and almost got a heart attack.
"Take what?" asked a voice what was unmistakably Twilight's voice.
Standing next to the bed was Twilight with nothing but his panties on. That majestic DD-cup breast free for the whole world to see.
"Twilight? This isn't what it looks like. Hold on how did you get here?" Spike asked while trying to explain his awkward situation.
"Silly you did you forgot I'm alicorn and also one of the best magic users in Equestria? Also, I haven't been able to get you out of my head after our time together yesterday. I did some research but all I found was dragon mating and it made me think you even more so no help there." Twilight explained.
"Okay... So why your here then?" Spike asked not believing that she was saying what he was thinking.

"I did read that dragon tongue should make mares feel amazing. So I would like to try out this. Could you help me?" Twilight asked.
Spike was dumbfounded he couldn't believe his luck right now. "Sure you should lay down on the bed for this." Spike guided Twilight.
"You sure?" she asked and Spike just nodded. Twilight did as told Spike got down on her.
"Now just trust me Twilight you know I wouldn't do anything to harm you." Spike said and Twilight started to breathe heavily.
Spike separated Twilight's legs and used his claw to cut the panties open. Spike was surprised that Twilight was already soaking wet. "Naughty girl" Spike said with a predatory grin.
Twilight was blushing heavily "I'm sorry Spike." she said.

"Now try not to crush me with your thighs." Spike said and went to work his magic on Twilight's pussy
Spike was lapping around Twilight's marehood and Twilight's breath quickened with each lap Spike did.
After a short time, Spike decided it was time to take it to another level and nipped Twilights erected clitoris.
This caused Twilight to scream and climax. Twilights cum exploded all over Spikes's face. Spike just lapped all the cum she could take while having a predatory grin on his face.

"Gods Spike that felt amazing. Not one of my toys can bring me to this kind of release." She said
Spike couldn't believe Twilight had sex toys."Wait you have sex toys? Where? I thought it was your first dick you saw yesterday." he said
"It's pretty easy to act all innocent if you know what to do." She answered.
Spike smiled. "Oh so you really are a naughty filly. What does my naughty filly want to do now?" He asked. While showing his erect dragonhood to Twilight and masturbating.
Twilight's eyes were mesmerized by Spike's tool. "I would like to... to..." she tried to speak while Spike was rubbing her clitoris making it hard for Twilight to focus and speak.
"You have to speak up Twilight I can't read minds." Spike said grinning and stopped rubbing her.
"Fuck me please Spike!" Twilight almost yelled like her life depended on it.

Spike aligned himself with Twilight's entrance. "Before we do this you know I'm in a relationship with Rarity?" Spike asked.
"I know. Don't worry I have a solution to this. Now come on show me how dragon does it." Twilight answered.
Spike pushed himself inside Twilight vaginal making way to his dragonhood. Twilight was tight but she wasn't virgin tight and there wasn't any blood
"Your not a virgin?" Spike asked
"Technically no. But I haven't been with a stallion unless you count my dildo." Twilight answered.
Nodding Spike continued. Pushing in pulling out repeating this action in and out with a steady and ever-increasing pace each time his dick reached a little further and closer to the entrance of Twilights womb.
"Gods Spike just don't stop please!" Twilight yelled in pure ecstasy.
Spike continued to hammer into her while fondling her amazing tits nipping and sucking on them.
This caused Twilight to orgasm she loved when Spike played with her mammaries she did it to herself too while playing with herself.

Spike could feel his release closing in as much as he would love to see Twilight round and heavy with his child he still had a little amount of sense left in him. "Twily I'm close..."
Twilight wrapped her legs around him pushing Spike back inside. panting heavily she spoke
"Don't worry Spike I'm safe. My heat won't start until next month so please give me all your love" She spoke.
All sense left Spike and instinct took its place ordering him to seed this female pulling once more back and pushing back inside with all his might Spike managed to push his knot in locking them together. Spikes' balls worked overtime releasing all of their sperm inside Twilight's womb. Spike opened his mouth and let out a small roar.
Twilight could feel Spike's sperm inside her womb trying its best to reach her ovaries in hopes to find an egg to fertilize. "Oh sweet Celestia this is so good." She said while holding onto Spike.

Spike's instincts withdrew he looked that he was tied with Twilight. "Well better get comfy Twi were going to be together for a moment." he said.
Twilight gave a warm smile and kiss on his mouth. "That's quite alright Spike. I was planning to sleep in here anyways." She said.
"So what do we do now you know I love Rarity, but I love you too." Spike said.
"Shit this is one bad mess I am" Spike thought to himself.
"Don't you worry your head my special drake. I did some research and I believe I have an answer for this." Twilight answered.
Spike pulled the blanket over them and Twilight grabbed him harder
"Please don't ever leave me." She said pleading
"I won't Twily." Spike said kissing him once more
After that, they drifted into blissful sleep.
