Luna walked through the halls of Canterlot. Alone.

She thought it wise, what with the nation still learning of her return, and she was still unsure how they would come to react if they found out Nightmare Moon, the ancient evil, was not only 'cleansed' of her evil and expected to live among them, but was also to eventually take the reigns of Equestria alongside her sister again. True, she had gotten an almost inexplicably warm welcome in that Ponyville town, but she hadn't lain waste to it, not like the castle she was in now.

Thinking of such damages, she came upon the very same halls, still littered with some debris, but all broken weapons and scattered soldiers removed. She closed her eyes and began to think of the night before. All the screaming. The crying of troops and civilians alike. The spectacular beating she applied to the Captain. That Cadenza pony whom she had squealing in her grasp. That wondrous stallion that gave her the first proper rutting in eons...

Her eyes snapped open, and she immediately clutched her head with her hooves in shame, something she did increasingly as of late. That stallion! Her own sister's husband! How could she do such a thing?! She had forgiven her for trying usurp the crown and shroud the land in eternal night, but what would she say if she coerced and laid down with her beloved!? Surely, she thought as she clopped down the corridor, he will say something if I do not speak to him. I must find him quickly! With that goal in mind, she raced down the hall, in search of the Sun's Stud.

Blueblood awoke groggily in his bed. He wondered what had become of the madmare he had been forced to rut the night before. Though, if the sky was any indication, her idea of 'an Eternal Night' proved as unlikely as he'd thought. He hoped intensely that her other plan of making him her stud failed just as hard.

He was able to drag himself out of bed, and spotted his bedside table. There was a vase full of flowers, with a small card that said:

Rest easy and get well soon, little brother!
-Cady

Oh, his dear sister was alright. There was good news. Perhaps he would go downstairs and see if he could get any information on what that animal wanted. Or he could stay in his room and have a drink. Nah, he would go downstairs.

He opened the door to his room to see a light blue shape streak across his path. It immediately stopped before it rounded a corner, and looked behind itself. It was a mare. A rather young mare. With wings and a horn. Blueblood had never been made aware of an alicorn besides his aunt and sister, so he was rightly surprised. In fact, the only other one he'd ever seen was the one that attacked him last night.

But he didn't have much time to process the information, as she froze at his sight, before shrinking down to a submissive stance. He did however notice the sad little sparkle in her eyes that were such an appealing shade of teal....

"Um, I...hello, sir." she said, being careful not to make eye contact with him.

"Hello?" he offered, "who might you be?"

She gulped, and tried to raise her head a little. "I'm Luna. My name is....Luna."

Beautiful name. the prince thought. "And, was there something you needed, Luna?" he said, walking up to her, causing her to shrink back even more.

"I...well, I..." she stammered. Blueblood just looked at her squirm uncomfortably, unable to get out whatever information she needed to communicate. She flushed and fidgeted and rattled her little black regalia pieces. He soon grew tired of waiting.

"Look, miss," he said, catching her attention and finally drawing her gaze directly to him, "You could have just sent me a letter if my presence is this difficult for-"

"I'M SORRY!" she finally blurted out. The outburst silenced Blueblood, who could only watch on as more apologies streamed from her deeply saddened face. "I'm sorry for what I did to you! I couldn't control my urges, and I shouldn't have forced myself on you! And I swear, if what I've done affected your relationship with Celestia at all,"

She suddenly found herself silenced as Blueblood thrust a hoof forward, holding her muzzle.

"Just hold on a second! What are you going on about? When did you force anything of yours on my person?" he asked, removing his hoof. The prince was no stranger to being sought after by suitors. With his sister spoken for and his Aunt a star no one dared touch without being prompted, ponies more often than not, aimed for him when seeking some Royal Loving. He'd gone so far as to compile a list of the mares (and horrifyingly, stallions) that tried to entice him, and he knew he would have remembered a cute little alicorn this emotional.

She took a few breaths. "I...I am the one who attacked you last night, and I am eternally sorry for the transgression, sir. I truly, truly am." There were a few tears forming at the corners of her eyes, and she looked forlornly at him, waiting for a response.

Blueblood just stood there, staring at her. Then he grimaced horribly. "That was you!?" he asked, backing up a little. This adorable little lady was the same black furred marauder from the night before!? "What happened to you?"

"I was...cleansed of my darkness, sir. By the Elements of Harmony." Blueblood had no idea what those were. All he knew was that Nightmare Moon was back, right in front of him. Tiny, blue, and begging forgiveness. The reality, when it hit him, set the gears in his head turning.

"Well, that's all well and good, miss," he started, and Luna seemed to get some hope in her before he continued with, "but, who will cleanse me?" Her face fell. "Who will remove the memories? Of being scared nearly to death as my home was ravaged by screams and explosions? Of having dear, sweet Cadance kidnapped? Or how about beating and bloodying our brave, selfless guards?"

Every part he dredged up made Luna hold her head lower and lower, until her head was touching the floor and some tears flowed down her face slowly. "And at the end of it all...taken advantage of by the mare responsible for it all." He put great dramatics on this last line, speaking of it in a grave tone and putting his hoof to his head in mocking swoon. "Oh, I don't know how I could ever sleep again, Luna!"

Looking at him from her prone state on the floor, the blue alicorn drew herself up, seeming to come to decision. She turned around and lifted her tail, exposing her blue vagina. Caught completely off-guard, Blueblood just stared at the sight, feeling a tingle in his groin as he did so. Regaining composure, he asked, "M-Miss Luna, what are you doing?"

She turned her head to him, no longer crying, but giving a small smile. "I want you to use me, sir. Use me like I used you. Surely, that would make some amends for the personal crime against yoooooOOUU!" she squealed, as she felt a sudden dampness at her nethers. Blueblood gave her a few rough laps before drawing back and licking his lips. Still cool. But now it was sweet.

He stepped aside from the door to his room, tapping her rear to direct her inside. "Please, do come in, dear. And by the way, it isn't 'Sir,'" he told her as she walked in. "It's Blueblood."

The room was immaculate, as was befitting of royalty. He led him past his expansive wardrobe, modest bookshelf, and strange, padlocked cabinet and made a beeline for the prince's bed. It was king sized, with ocean blue sheets, and Luna could feel how incredibly soft it was when Blueblood nudged her onto it. It was almost cloud soft.

The prince scuttled onto the bed himself. He was very eager to start, as his erection that had bobbing and throbbing since they entered the room was any indication. He turned to her with a very smug smile and angled his length at her head. She gulped nervously. It seemed bigger than before.

"Go ahead, dear," he purred. "earn your keep."

She took the length in her hooves, it twitched at her touch, like an excited animal. Rubbing it with her hooves, she took her time feeling its hardness and warmth. This elicited a small groan from the prince. She brought the member to her chest, adding her furred stomach to the sensations.

"Ohh, yes." the prince moaned, his back leg shaking a little. Encouraged, she scooted closer to him, so that her thighs came close to his own. She continued to hoof the prince's erect phallus and slowly brought her body forward, burying the majority of his penis tightly between their bodies. This excited Blueblood further, who began to thrust into the space between them. As he did, clear pre leaked from him, and the thrusting smeared the stickiness all over her chest. A few particular hard ones got his member to poke her lips. Looking up to see an approving nod from the prince, she obediently opened her mouth.

Blueblood immediately dove his head inside, getting a muffled yelp from Luna. He moaned as he used the soft, cool wetness of her mouth, which Luna helped along with a flick or lap of her warm tongue every other movement. He began to thrust faster, his orgasm building fast. He attempted to tug out of Luna's mouth, but felt resistance. He looked down to see that she had held fast to him and was actively suckling his member. It felt nice, but he had no intention of finishing there.

With a sharp tug, he came free of her mouth, to which she whined in protest. But before she could return it, Blueblood held her off with a hoof, using his other to quickly finish himself off. He directed his length at Luna's face, and came. A few white ropes of seed landed on her face. Luckily, she closed her eyes before they hit, letting them land harmlessly in her eyelids. She opened her eyes again, wincing at some of the wetness on her face that she wiped away with a hoof. She gave it a lick afterwards, and did not find it terrible.

"Huff...Alright....now turn around." the prince ordered. Luna did as she told, lifting her rear and tail expectantly. Blueblood took some time to admire it. Petite, tight, getting wet, and the dark portions of her strange cutie mark actually met in the middle of it. Cute.

He moved his body over Luna's body, but did not penetrate her. Rather, he straddled her, sandwiching her body between his own and his penis. His throbbed harder as he rapidly rubbed her with his member, slathering him with her secretions. Humping her like this, her arousal grew, and the moisture from her entrance increased. She fidgeted from the friction, and began to mewl.

"Ohhh please, Sir Blueblood, ah! I beg thee, take your pleasure and tease me no longer!"

She was right, he decided. No reason to stall his gratification. He stepped back, allowing his member to jerk up and align with her hole properly. Prodding her slightly, he finally slid inside her, working himself halfway in. Luna moaned a little at the feeling.

He gave a few shallow shoves, and thought about how her insides felt now. They were no longer a biting blizzard of pain. There was a coldness, but it was relaxed, a subdued kind of cold. And there was an underlying warmth buried in there. The whole thing was like a patch of snow, hiding the heart of a scared, fluttering little bird.

Harshly, he shoved himself the rest of the way in, hitting the entrance to her womb. This got Luna to let out a yelp of surprise. But Blueblood ignored her and set to work, slowly fucking her and building into a rhythm with his thrusts.

Luna panted, loving the way he worked her over. It had escaped her entirely that this was meant as an act of penance on her part. She just enjoyed being rutted by her sister's stallion. Feeling him put more weight on her head, she looked to see he was in her hair, sniffing it deeply. Smiling, she stealthily bent her forelegs, letting her front half rest on the bed. Then she moved her hooves under her, to the marehood currently being steadily pleasured. But before she could help herself, the powerful pounding stopped.

Blueblood lifted himself off her back. Hooking a leg under one of her own, he flipped her onto her back. Luna's surprise was such that she was almost overwhelmed when he bent over he and did her faster than before. She began to moan and writhe with his newfound energy, and her orgasm built up fast.

The prince, meanwhile, felt some strange things of his own. To have an alicorn, a kind of pony powerful simply by virtue of existing, a pony any other pony would kill to be in favor of, let alone rut at their leisure beneath him felt empowering. He felt incredible. Superior. Dominant. He looked down at Luna, her face scrunched, orgasm seconds away. Giving in to his insane impulse, he gave savage growl, and bite down hard on Luna's shoulder.

Her eyes shot open.
"Eyaaaaaaaaahhhh!" Luna screamed in ecstasy as her marehood clamped down on the prince's dick, and she wrapped her legs tightly around his neck. Her fluids gushed in torrents, making an awful mess on his bed.

Blueblood felt it, but hardly reacted, opting to hammer through her cumming to focus on his own. As he came closer and closer, with Luna babbling praise in his ear, she changed. In the prince's haze of arousal and instinct, she changed. Her fur was suddenly white. Her hair had shades of green and pink added to it. And suddenly it was his aunt that he was fucking with abandon.

No! he yelled internally, trying to force the image out of his vision. It worked, and once again it was little Luna that was in tears for his touch. But it did not last long. For soon, she changed again. This time, his sight was flooded with pink, and the hair was decked in purple, yellow and more pink. He could swear an all-too familiar voice was encouraging him, egging him on, telling him what a good, strong stallion he was.

Well, fuck.

Blueblood came. Hard. He thrust inside Luna as far as he was able, his member almost painfully hard. He pumped her full of his thick load, snorting and gritting his teeth like a desperate animal. When his spurts finally ceased, he stood there, breathing heavily, before letting go of Luna's shoulder. The bite wasn't too deep, but there was some blood dripping from it. Exhausted, he languidly pulled out of her, releasing a flood of his seed as he did so, and fell forward, making sure to land beside Luna's heavily worn form.

He lied there, his breathing ragged. Luna managed to scoot over to him, and wrapped his large hooves around her neck. From his position, he could see the bite wound he left.

"It's alright, Sir. Tis not a grievous wound." she assured him. Her horn glowed a soft blue, and the flesh was knitted in seconds, leaving only a few specks of blood and a barely noticeable scar behind. Blueblood settled into his bed, and drifted off, Luna settling into his broad chest. Just before he slipped off, he could hear her musings. "Sleep well, my king...."

Blueblood was the first to wake. It was beginning to get late in the day, the clock showing it was well past noon. No doubt the rest of the family would be wondering where he was. He was surprised Cadance hadn't come knocking. But he could focus on that later.

He slowly left the bed, which he noticed reeked of his and his partner's act. The smell was pungent, but somehow gratifying. Making his way to his bookcase, he searched the tomes for the right book. He found it, with a snake emblazoned on the spine. Taking it down with his magic, he flipped it to the appropriate page, where a key was hidden. Taking it, he strolled leisurely to the padlocked cupboard that occupied on corner of the room. Unlocking it, and tossing the lock side he opened it reveal his private collection. Of alcohol. Celestia preached the virtues of a life without such a vice since before he was born, but she didn't put up the fuss he had expected when she discovered this cupboard for herself. Ales, wines, and spirits from all over Equestria were here, and Blueblood couldn't think of any other way to follow a good rutting.

Skimming the labels, he eventually chose a bottle he acquired from a supplier in Ponyville. A bumpkin town, to be sure, but in this case, good liquor was good liquor, wherever it came from. He took a glass from inside the cupboard as well, getting a second after some thought. Maybe he could stoke that little bird's heart into a real fire.

Pouring both drinks, he moved to take a sip, but was interrupted by a knock at the door. Setting one drink down, he answered it. It was Shining Armor, patched up and in much better condition than before. He opened his mouth to greet him, but scrunched his face up, no doubt at the smell that permeated the room.

"Ugh, hey B. Good to see you're feeling better." he asked, though he was clearly disgusted.
"And you as well, Armor. Tell me, how are things in the rest of the castle?"
"Oh, we're fine out here, the city's calmed down and there were no serious injuries to the guards. But, I came to ask if you've seen Princess Luna?"
"Princess Luna? Oh, well I might have seen her around." he said haughtily, taking a swig of his drink.
"C'mon, B, Celestia wants to know if her sister is alright."

Blueblood spit out his drink just to the side of Shining's head, and coughed harshly before he continued.

"H-Her sister?" he choked.
"Yeah, I was surprised too. I got beat by boss's little sister."
"Oh, i-is that right?" Blueblood responded shakily. The drink is his magic grip wouldn't hold steady, and the drink splashed out of it, while he tried and failed to keep a smug smile.

"Yeah, I even talked it over with her. Turns out she doesn't have any other sisters, so it turns out that she's like, your great-great-great-great-great-grandma!"
Blueblood had a hard time keeping his stomach steady. His grandma. His grandma. He just got done rutting his grandma's brains out! A second time!

"Well, urp, if I see her I'll tell her you're, ugh, looking for her."
"Thanks, B. And please, be nice to her. She's kind of low right know and doesn't need to be given a hard time."

And with that, Shining limped away down the hall. Blueblood slowly closed the door, and held his mouth in his hoof, desperately trying to keep himself together, he then heard the clopping of hooves behind him, and turned to see Luna, with a drink glass floating beside her.

"Mmmm, Sir Blueblood? I hope you don't find this callous of me, but I am curious. Now that you have had me and my sister, whose loins do you prefer?"

I felt the clop wasn't done very well. Thoughts?
