"My king! Nightmare Moon and Celestia approach!" The guard declared, out of breath

The king rose quickly in his seat. Zebranica was his. He would not back down against any threat. "The rest of you hide. I shall face these beasts." He growled. But a moment later a glow enveloped his guards, throwing them to the side. Were they unconscious? Dead? There was no time to check as Nightmare Moon herself came from the very shadows themselves. The threatening armor clad mare that had been on a tear through the world. Conquering any in her path and destroying all others. Nightmare moon. The mare who had declared the night would last forever and that the world would be hers.

"Such a pain. I would really rather have dealt with this a bit quieter." She said with a sigh as she stepped over one of the bodies. The door at the entrance of the hall gently opened. The pet of the Nightmare and the first pony to break under her power.

The former Princess Celestia gently stepped through, shutting the door just as gently. She herself was wearing a thin dress. Through which one could see her body. Wide hips, large, pillow like breasts which sported a chain connecting her nipples and a cock larger than most stallions hanging between her legs. Her face however had a disturbingly calm expression, despite the blood and ashes on her cheek. "The rest are taken care of Moony" She said with a giggle as she tried to levitate something through the door she'd shut. A thud was heard and she turned around with another giggle "Whoops." She opened the door and pulled a beautiful zebra mare through it. Ashes covered much of the mare's body. What had once been her personal guards. "And I found her."

The king's eyes widened. He had heard tales of what the Nightmare would do to ponies. Especially beautiful mares and his queen was the most beautiful of the land. "You monsters" He growled but Nightmare didn't even turn to him.

"You silly foal. You got someone on your cheek" She said as she walked up and brushed it off for her before leaning down and taking a handful of the queen's mane.

Ignoring the screaming mare who was being lifted into the air, Celestia blushed "Oh, thank you Moony."

Her back turned, the King hoped that she wouldn't notice him rushing. He didn't shout. He didn't cry out. he simply rushed.

Tia looked past Nightmare and giggled at the sight. It was only then that he realized just how hopeless his attempt was. Nightmare reached behind herself, her hand wrapping around his neck, bruising his throat as he ran into it.

"Oh, Moony. He wants a front row seat!" She said as Nightmare lifted up the Queen to face him. A cut on her forehead causing her to keep and eye shut.

"I think he does." Moon said with a giggle as her tail wrapped around him. the ethereal darkness prevented any movement of his own. As if she were in her own room she began the intricate process of undressing from her armor as she spoke again "You go first." She said simply

"Of course Moony" She said as Nightmare dropped the queen to the ground roughly. Celestia picked her up quickly after. Her still creepily calm smile on her face as she ripped the clothes off of her. "It's rare that Moony lets me go first." She commented with a giggle before turning them and making sure that the King would have a full show.

"Unhand me you monster! Beast! Evil!" She screamed, trying to beat at Celestia who didn't even flinch as she lifted her dress and with no decorum, forced herself into the queen. The queen's scream echoed through the castle. But thanks to Tia there were no more guards to rush to her protection.

The king shouted his empty threats, his anger but Nightmare just hummed to herself as she forced him to watch Celestia rape his wife. She didn't care for his words. Her goal was domination. Breaking them down until they were something useful. "Make sure to mark her outside. Her womb is mine" Nightmare said over her shoulder as the last of her armor came off. Celestia was big. But Nightmare moon's cock was as much of a monster as she was.

"My womb will never be yours! I shall never bear your foal! You fucking MONSTER!" the queen screamed before gasping as a moan escaped. She couldn't help it. Celestia had hit the right spot. the one that her husband had never been able to quite find.

"It will." Moon said simply as if it was fact. "Now. Let's see here" She said as her tail pulled away from his crotch. "Oh my~ you like watching this?" She teased as she pressed against his erection. It bounced at her poke as her fangs gleamed in the light. Her grin terrifying. "You like watching your wife be taken against her will?" She asked as she gently stroked him

"No! Never!" He shouted, trying to look away, only for the tail to force his head back to watch

"Really? Hmm. Because I see different" She said as with a loud moan Celestia pulled out, her pure white, hot cum landing on the Queen's body. "Pet. Tend to him. But don't let it end quickly" She ordered as she walked over to the queen

"Yes Moony" She said with a giggle as she stood, walking over to the king as her cock continued to dribble cum. She kneeled and took his cock into her mouth, moaning as her tongue flicked over it's tip.

Nightmare pet Celestia as she passed and picked up the Queen. "You. Are mine" She said as she grabbed the queen's hips and slammed her down, forcing her onto the massive shaft, spearing into her and causing an obvious bulge on her body as it traveled up. The Queen screamed in both pain and pleasure. Her mind shut down as an orgasm rocked her body. Nightmare would ruin her. Ruin her for anyone.

Nightmare's magic encased her mind as she moved her hips. She didn't want her to JUST break. She had to break the right way. "Take it. You may be a queen but you are MY WHORE" She declared as she pulled back, only to spear herself deeper. She was pleased to hear nothing but a garbled moan

the king could taste blood as he bit his lip, trying to ignore the pleasure that he was receiving. The former princess taking his length with ease as he was forced to watch this.

Nightmare looked back at him with a smirk "I've heard that you were so, so proud of what's in my sister's throat" She said as she began simply using his wife like a sex toy, allowing time for her magic to work. "But I'm sure that she could never go back to you anymore" She chuckled and slapped her mostly unresponsive toy "I'll be the only one who can please her. In fact. Do you even need to please anyone anymore?" She asked before looking down at Tia and nodding "Finish him."

What the king felt next was beyond his wildest dreams. He couldn't describe what was happening. Suction, tongue, lips. All of it somehow working together and within moments he couldn't hold back anymore. He came while Nightmare cackled.

"Congratulations! You came while watching me take your wife" She teased before humming as she watched Celestia's cheeks bulge with his cum "Spit his dirty seed out. Only I deserve to fill you." She ordered which was quickly followed with Celestia spitting any and all of the cum onto the floor.

She grinned as she looked over his defeated expression "Delicious." She said before groaning in pleasure. Her toy bulged out with cum, her last scream echoing before morphing into a whorish moan. It was done. She grinned as her cutiemark appeared on the queen's belly, proving that her heir would grow inside. She pulled the mare up by her neck before throwing her to the ground and facing the king.

"Hmm...no. No, I don't think you will be needing it anymore" She said with a smirk as her magic enveloped his cock "I think I'll some to my pet." She said as he began to shrink. He stared in horror but was too exhausted to do anything more.

Tia moaned as her cock grew in size, as did Nightmare's already frightening size. It didn't take long for his cock to disappear from his body. His entire size stolen by the empress of the night. "There. Now. Since you don't have anything, I can think of something else for you to do." She said with a hum

"Do what you want monster. You have already destroyed me" He said, looking at the floor.

She shrugged as her tail let go of him. He fell to the floor and didn't move. He knew it wouldn't matter. as his body was enveloped by magic he just sat. If he was killed, changed, then so be it.

Nightmare grinned as she watched his body change. Become more feminine. She wanted another heir. It would be entertaining down the line to have siblings fight over who will come and worship her in Canterlot.

She pushed his - her back to the floor as her cock dripped onto her face "You'll be the same as her. But I'm going to enjoy doing this the slow way" She said with a grin as she backed up and aimed. "Long Live the Night" She declared before once again capturing another nation. It wouldn't be long until it was all hers. All of it and everyone in it.

This one was a lot darker. Clearly I don't endorse anything. I was just in a mood to write dark
