"Princess Luna."
Luna awakened immediately with a gasp, opening her eyes wide, shocked from the experience of hearing another voice. She looked to her side, her eyes reflecting both her drowsiness and her fear. She gained sight of her big sister, head held high and wings spread wide, looking down upon her.
"It has been a thousand years since I have seen you like this."
Hatred seeped from her voice, but only enough to be detectable by Luna and Luna alone.
"Time to put our differences behind us. We were meant to rule together, little sister."
"Sister?" Three ponies behind Princess Celestia all said in unison.
"Will you accept my friendship?" Celestia veiled her anger by standing and giving a smile. Luna closed her eyes, trying to think of the best thing to say to attempt to regain at least a slight amount of satisfaction from her sister. Looking up quickly, she made her choice. Pouncing up to her, she spoke quickly.
"I'm so sorry! I missed you so much, big sister." She let her tears slip past her closed eyes, pelting one or two onto her sister's shoulder. She also felt small pecks on her back. She thought her sister was crying as well, but the tears weren't fully wet. They were crafted with Magic.
"I've missed you too."

After the celebration of her return in Ponyville and Canterlot, the two Princesses were in the great hall, alone. "Sister..." Luna said cautiously and quietly, not wanting to do anything to disturb Celestia's mind.
"Yes, Luna?" She replied, no tone in her voice at all, no emotion at all.
"Are you.. are you still..." Luna gulped, fearing the answer.
"Still mad at you for turning into a power-crazed, vengeful-for-no-reason monster? Mad at you for trying to kill me just to take over the throne and have your night last as long as you wished, just so you could be loved by everypony like me?! Oh, sister..."
Princess Celestia towered over her younger sister, talking in a harsh tone. "You still have one punishment I have planned for hundreds of years for you to receive. One last trial for you to endure before I even think about forgiving you. This is my castle, my throne and my rule."
"Sister, why?! I've endured unbearable loneliness for a thousand years for you! What else do you expect me to do?!" Luna poured the words out faster than she expected, and she immediately regretted her action, even if it was just to help defend herself.
"Oh, this isn't going to be too bad, not as bad as what I could do to you instead, but still, you will experience pain, just like the pain you put me through, but oh so different. Ponies all across my kingdom worship me. I am not about to lose the love these ponies give me because you came back.
"And I am not going to let you get any free love or affection, when you first came back, you still tried to kill the ponies under my rule."
"That was Nightmare Moon, not-"
"I DON'T CARE. You and Nightmare Moon are the same. You both desire popularity, love and power. I will not allow you anything until you've endured your last trial. Do you understand that?" Peering down at her younger sister, Celestia silently demanded an answer.
Speaking from pure fear, she accepted. "Y-yes, sister Celestia." Laying down and shaking in a defensive position, Princess Luna closed her eyes and lowered her head down to the ground. "B-but.. it's you..." She barely uttered out her beginning words, praying that her sister didn't hear her.
"It's me? What's me?" She demanded harshly, staring holes into her younger sister's body, if it was possible.
"It's you that's.. IT'S YOU THAT DESIRES LOVE AND POWER!" She shouted, standing on her hooves fiercely, preparing herself for anything her sister sent her.
"How DARE you! You return after being gone for so long just to tell me I'm selfish?! What is wrong with you?!" Celestia, out of anger, fired a magic bolt to her sisters head, the impact causing a slightly bloodied nose and a knock-out.

When Luna awoke, she slowly opened her eyes. She tried to raise her hooves and rub them, to try to help convince that what she last remembered was a dream, but her hooves were blocked by something. She tried to pull her head back, but something also blocked that.
She leaned forward from where she was now standing, trying to get a view of herself. Her sight was blocked by two wooden planks locked together with a circle large enough for her neck, but not any other part of her body in the trap. She looked up, fear in her eyes, and saw a large blade.
"AAAAAHHHH!" She screamed in fear and panic, trying frantically to get free from the immobile head prison. "SISTER! HELP!" She screamed frantically yet again, pleading for release from the old execution block. She caught sight of a bright, flowing mane, just before her sister walked in.
"Luna, calm down. This is part of your punishment plans."
"Plans?! You sick person!" She retorted harshly. In response, Celestia lit her horn and cast a small lightning spell onto the shoulder of Princess Luna. "AGH!" She screamed in pain, trying to crawl away from her entrapment to no avail. She started to charge her horn with magic, but was cancelled by Celestia sending a small bolt to her horn.
"I would advise against using magic, if I were you. If you use the slightest bit more magic, the blade above your neck is going to fall down, slicing your head off and killing you. If you wish to live through this and be accepted by me, you must endure what I plan for you.
"I've planned for you to have the company of the largest stallion in the entire Royal Army. Guard, step in here now, please." Celestia asked kindly. A moment later, a smirking Royal Guard stepped from the shadows beside Princess Luna.
"Hello, my Princess." The guard spoke harshly, making Luna cringe.
"Luna," Princess Celestia spoke. "I would like you to meet Cosmic Longsword. He's going to be the one to deliver your punishment." Luna looked to the guard with fear and nervousness, afraid of what was going to happen to her after Celestia left.
And unfortunately for her, Celestia left without a single other word.
"So..." The guard spoke softly. "Ready for your first session?" Luna refused to answer as long as she could, making sure to analyze every detail of the stallion. He had a bright blue mane, poking out above his head because of his helmet. His coat was as white as Celestia's. His armor covered his Cutie Mark.
The only thing that truly threw her off was his size. He wasn't even as big as Big Macintosh.
"I'm going to take that as a 'yes' then." He said happily, walking over to behind her, out of her sight. It scared her and made her nervous beyond all comprehension to be locked in position, unable to look behind her, unable to protect her hind quarters from showing everything. The only true protection she had was her tail.
To her greatest fear, her tail was moved to the side by a hoof. She felt warm breathing on her flanks. 'No, no, no. This can't be real. This can't be-' "AH!" Luna screamed from surprise, making her jump from her thoughts. She received a long lick on her mare-hood.
"Surprised you, didn't I?" He said deeply and proudly. Princess Luna was about to charge magic to release herself, but then she remembered about the blade above her head. With her unable to cast magic and look up fast enough to stop the blade, she had to endure, else she would kill herself.
Gladly, the stallion backed off and released her tail, letting her pin it between her legs, protecting her as much as she could. She saw the guard step into her view, and she received the greatest shock so far. His erection was hanging down freely, and the sheer size of it scared her witless.
"No, no, no, no, no. You can't be.. that's not possible! Tha-MMPH" She was forced into silence by the object being forced into her mouth suddenly. It was only the tip of it, yet it still was hard to hold. She feared that if he was any wider, he would break her jaw.
Reluctantly, all she could to was stand there and take what she received, as she was immobile because of the ring around her neck. She opened her eyes and gained view of his body, but not his face. Her head was being forcefully pounded into the wooden planks, paining the back of her head.
Thankfully, he stopped and pulled out, allowing Luna to gasp in breath. In her increasing fear, he walked towards her hind quarters once more. "I suppose..." He said slowly, leaving Luna wondering in nervous anticipation for what he was going to say. "I could tell you some comforting news.
"Princess Celestia used a spell on your mare parts to make sure that they didn't rip apart." She felt a long, thick warmth touch her left flank. "To be honest, I'm comparing sizes, and your behind isn't much larger than my tool of awesomeness." He pulled it away for only a moment. "You'd better be thankful."
He slammed an inch inside of Luna's swollen and soaking mare-hood, forcing it to the width of his pride. She felt pain beyond comprehension, as she closed her eyes and yelled out pathetically. He just kept pushing further and further inside, making her pain spread throughout her body.
Crying, she felt as if she was still going to rip apart, despite the supposed spell. Her pain clouded everything for only a moment longer before he pulled out. Her pain then started again as he pushed inside repeatedly. The pain slowly washed away, and her breathing steadily increased.
The less pain she experienced, the more pleasure she felt. The more pleasure she felt, the more pain she experienced. It was a vicious cycle of pain and pleasure, making her brain and her body miserable yet overjoyed. Not caring, she stuck her tongue out and yelled louder, drooling a large amount.
She was getting the bucking of her lifetime, by an erection she thought had too big a size to exist, but she could tell the difference between magic and reality, and it was anything but magic. She reached orgasm, yelling louder still as he kept relentlessly pounding into her.
He smiled and enjoyed himself fully, having the pleasure of rutting the Princess of the Night like this. Still smiling, he spoke. "I'm going to cum, and I'm doing it inside of you." Just as he finished his own speaking, he gave his final thrust and released spray after spray of semen deep inside of the Princess.
Frantically, just as he finished speaking, Luna tried desperately to reach up with her front hoof and free herself so she could move away, denying him of his prize, but she was forced to take everything as it was given to her. Breathing heavily, relaxing as much as she could, she laid down in defeat.
Gladly, when she laid down, he popped out of her swollen and bruised hind-quarters. She opened her eyes when she heard a specific voice.
"I see you've finished, and passed. I heard you from across the castle, you know. Cosmic Longsword, did the spell hold?"
"Yes, Princess."
"Good." She replied, casting magic from her horn. Luna looked in fear for a fraction of a second before closing her eyes and tensing her neck. "Sister, it's fine." Luna opened her eyes to see the blade safely floating in-front of her head. Sighing and slumping in relief, she closed her eyes again.
Feeling magic once more, she was able to slide her head from her position that she held for so long. She laid down completely for the first time in what felt like hours, making her relax everything so well that she had fallen asleep.

Waking several hours later on a soft surface, Princess Luna opened her eyes slowly. Reaching up with her hooves, she gladly rubbed them, relieving them of excess water and awakening them. Wiping the water from her eyelids, she opened her eyes once more.
To her relief, she was in her old bedchamber. It was very dark, however, so dark that she couldn't see past the edge of her bed. Slight fear radiating through her, she tried to crawl off the bed and get to the light source under her door. Thankfully, she reached it with no difficulty.
She opened the door, allowing light to spread throughout her bedchamber. To her horror, spiders crawled all over her floor, all around her bed and their webs were found in every crevice of the room. Screaming and running, she ran away from her room in search of her sister.
"SPIDERS! Celestia!" Princess Luna slammed her sisters bedchamber doors wide open, ready to start explaining the situation. "Celestia, spiders are all ov-..." She stopped her rambling forcefully, gaining clear view of the sight in-front of her. Celestia was laying on her back, facing the door.
"Oh, hello, sister." She looked up just when her sister did. "Cosmic Longsword and I were just..." Celestia looked back to her sister again. "Talking about you." Princess Luna was shocked beyond comprehension at the sight her eyes forced her to see.
"He needed to be bribed to be quiet about what we-.. about what I made you go through, and his only affordable wish was this." Princess Celestia ordered him to continue, and he did without hesitation. Princess Luna closed the doors and started to run back to her bedchamber.
Deciding to wait until the spiders were cleared out, she walked to the throne room. She explored every inch of the room, spending quite a large amount of time there. Celestia walked into the throne room with Cosmic Longsword, ordering him to return to his normal duties. Celestia gained view of Princess Luna.
"Sister." She said with a sad sigh. "Please, come here. I wish to explain myself." Princess Luna walked to her older sister slowly and cautiously, unsure of what was going to happen next. "Luna, sister, I wish for your forgiveness. What I've made you go through was uncalled for and torturous.
"As the Princess of Equestria, I should know to act better than that. I put you through a thousand years of pain just to bring you back to my anger and more punishment." Tears pelted the floor below Celestia's head. "Please, forgive me for what I have done."
Luna shook her head. "With such unjust actions you placed upon me, sister..." She raised her sister's head and made her look into her eyes. "I suppose.. with one condition."
